This application claims the priority of the Chinese patent application filed on February 13, 2020 with the application number 202020165624.X and the utility model titled "positioning circuit board, guide rail for mounting electronic price tag, and electronic price tag", all of which The content is incorporated in this application by reference.

Technical field

This application relates to the field of new retail technology, in particular to positioning circuit boards, guide rails for installing electronic price tags, and electronic price tags.

Background technique

In order to facilitate consumer users to purchase commodity objects, service providers usually set up a large number of shelves in physical stores opened offline, place commodity objects on the shelves, and display them for consumer users to view.

Taking a physical store under the "new retail" business model as an example, there are very strict requirements for the display of merchandise objects. Not only is the store required to place merchandise objects in a pre-designed display method, but also the display method is dynamically updated on a regular basis Adjustments, each adjustment may involve the repositioning of merchandise objects.

Specifically, when the display processing of the product objects is required, the display operation server can obtain the display mode information (for example, the display mode information can be embodied as the effect diagram of the product object display), generate the display task and send it to the display operation client to display It can be viewed by the workers associated with the display job client so that the workers can place the merchandise objects according to the display mode information, and after completing the display of the merchandise objects, submit the task completion information to the display job server through the display work client.

In the actual operation process, there may be the problem of random placement of merchandise objects. For this reason, the display operation server can also generate inspection tasks according to the display mode information, and send them to the inspection operation client to facilitate the association of the inspection operation client. According to the display information, the inspection personnel check the task performance of the inspection operators. Specifically, if the placement accuracy rate of the merchandise object exceeds the preset value (for example, the preset value is 98%), the inspector can submit the correct placement inspection result information to the display operation server through the inspection operation client. ; Otherwise, you can obtain information about the wrongly placed product objects (for example, the product objects placed on the first floor of shelf 1 do not match the renderings), and submit them to the display operation server, so that the display operation server can place them The relevant information of the wrong commodity objects is sent to the display client, prompting the operator to correct the placement of these commodity objects, and finally conform to the preset display method.

Such a manual inspection plan will consume a lot of labor and time costs, especially when the number of merchandise objects provided by the store is large (for large physical stores, usually tens of thousands of merchandise objects can be provided), the inspection efficiency In addition, the inspection effect is completely dependent on the inspection personnel, and human factors have a greater impact on the inspection results.

Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of this application.

Considering that after the merchandise object is placed, it needs to be bound with the electronic price tag, and the relevant information of the corresponding merchandise object is displayed through the electronic price tag, this embodiment of the application provides a guide rail that can be used to mark the installation position of the electronic price tag, The guide rail can provide at least one installation position, each installation position is provided with a corresponding positioning detection circuit, and each positioning detection circuit corresponds to a different detection voltage value. In this way, after the electronic price tag is installed on the guide rail, if it is located at an installation position where position calibration can be performed, the positioning contact of the electronic price tag can be electrically connected with the positioning detection circuit set at the installation position to obtain the first voltage value information Submit to the cloud server. In this way, the cloud server can determine the target installation location information associated with the first voltage value information according to the pre-obtained association relationship between the installation location information and the voltage value information, and then obtain the electronic price tag association according to the installation location of the electronic price tag Based on the placement position of the commodity object, the execution result of the display task associated with the operator is automatically verified.

As an example, the electronic price tag can be a passive electronic price tag, and the guide rail can correspond to an active guide rail. After the electronic price tag is installed on the guide rail, the electronic price tag can be powered by the guide rail.

The implementation scheme of the electronic price tag and guide rail in this example will be explained below with reference to the schematic diagrams shown in Figures 1 to 3.

In this example, the guide rail may include a guide rail body and a positioning circuit board. Wherein, the guide rail body includes a guide rail groove opened in the extending direction of the guide rail, and the positioning circuit board can be installed in the guide rail groove. As an example, the positioning circuit board can be fixed in the guide groove by integral molding; or, under the condition that the shape of the positioning circuit board matches the shape of the opening of the guide groove, the positioning circuit board can be detachably installed In the guide groove.

Referring to the schematic diagram shown in FIG. 1, the positioning circuit board in this example may include: a circuit board body; Low-voltage contact wire 20 (for example, the low-voltage contact wire may be a ground wire); a power supply, the high-voltage output terminal of the power supply is connected to the high-voltage contact wire, and the low-voltage output terminal of the power supply is connected to the low-voltage contact wire; and, At least one positioning detection circuit 30 is arranged at intervals along the extension direction of the high-voltage contact line, the positioning detection circuit is connected in series between the high-voltage contact line and the low-voltage contact line, and each positioning detection circuit corresponds to a different detection circuit. Voltage value.

Specifically, the positioning detection circuit may further include at least one positioning detection sub-circuit connected in series (only a solution including one positioning detection sub-circuit is shown in FIG. 1), and the positioning detection sub-circuit may include a voltage dividing contact line. 31. The first resistor 32 and the second resistor 33. Wherein, the voltage dividing contact wire is arranged between the high voltage contact wire and the low voltage contact wire; one end of the first resistor is electrically connected to the voltage dividing contact wire, and the other end forms the input terminal of the positioning detection sub-circuit (In the example shown in Figure 1, the input terminal is electrically connected to the high-voltage contact line); one end of the second resistor is electrically connected to the voltage dividing contact line, and the other end forms the output terminal of the positioning detection sub-circuit (at In the example shown in Figure 1, the output terminal is electrically connected to the low-voltage contact line).

Preferably, for ease of operation, the length of the partial pressure contact line can be set slightly longer, usually not exceeding the length of the electronic price tag. In this way, it is convenient for operators to operate, as long as the positioning contact of the electronic price tag is electrically connected to any point of the voltage dividing contact line; it can also prevent the adjacent electronic price tag card from being installed on a positioning detection circuit, resulting in installation The location information is determined to be wrong.

Preferably, the positioning detection circuit can be slidably connected to the high-voltage contact wire and the low-voltage contact wire. In the actual application process, the operator can flexibly adjust the position of the positioning detection circuit according to the position of the commodity object to make it correspond to the position of the commodity object. In this way, when the electronic price tag card is installed in the position of the positioning detection circuit, There can be a one-to-one correspondence with the commodity object, which is convenient for consumers to view the relevant information of the commodity object bound to the electronic price tag.

As an example, the positioning circuit board in this example may further include: a first sliding rail, the high-voltage contact line is arranged in the track of the first sliding rail; a second sliding rail, the low-voltage contact line is arranged in the track Within the track of the second slide rail; and, a sub-circuit board corresponding to the positioning detection circuit one-to-one, the sub-circuit board includes a first terminal slidably engaged with the first slide rail and a The second sliding rail is slidably engaged with the second terminal, and the positioning detection circuit is slidably connected to the high-voltage contact line through the first terminal and slidably connected to the low-voltage contact line through the second terminal.

During use, a set of jumper pins can be short-circuited through the jumper cap 50, and different shelf layers can be marked accordingly. Take the schematic diagram shown in Figure 2 as an example. For the guide rail installed on the first shelf, _{the jumper pin corresponding to R row1} can be shorted by the jumper cap; for the guide rail installed on the second shelf, Jumper caps can be used _{to short-circuit} the jumper pins corresponding to R row2; for the rails installed on the third shelf, the jumper pins corresponding _{to R row3 can be short-circuited through the jumper caps.} In this way, even if the resistance values of the positioning detection circuits in the three rails are exactly the same, by selecting a third resistor with different resistance values, the voltage values of the positioning detection circuits at the same subdivision position can be distinguished. In other words, the voltage value can be used to determine which rail the electronic price tag is located at and at which subdivision position of the rail.

Referring to the schematic diagram shown in FIG. 3, the electronic price tag in this example may include: an electronic price tag body including a first surface and a second surface correspondingly provided; a display screen provided on the first surface; and, Two power contacts 61, 63 and at least one positioning contact 62 are arranged on the second surface, the power contacts and the positioning contacts are arranged along the height direction of the body; a controller and a communication module, The controller is used to obtain the voltage value information collected by the positioning contact, and submit the voltage value information to the cloud server through the communication module.

Understandably, if the positioning detection circuit includes at least two positioning detection sub-circuits connected in series, the electronic price tag may be provided with at least two positioning contacts correspondingly, and the at least two positioning contacts may be connected to at least two positioning detection sub-circuits respectively. The voltage dividing contact line in the circuit is electrically connected. Each locating contact can separately collect voltage value information at the voltage dividing contact line of its respective electrical connection, and uniquely identify an installation location by combining at least two voltage value information.

Or, as another example, the electronic price tag may be an active electronic price tag, and the guide rail may correspond to a passive guide rail, that is, a power supply is provided in the electronic price tag.

The implementation scheme of the electronic price tag and guide rail in this example will be explained below with reference to the schematic diagrams shown in Figure 4 and Figure 5.

Referring to the schematic diagram shown in FIG. 4, the positioning circuit board installed in the guide groove may include: a circuit board body; a low-voltage contact wire 70 arranged on one side surface of the circuit board body; and, spaced apart along the extension direction of the low-voltage contact wire At least one positioning detection circuit 80, and each positioning detection circuit corresponds to a different detection voltage value; the positioning detection circuit includes a voltage dividing contact line 81 and a fourth resistor 82, and one end of the fourth resistor is connected to the voltage dividing contact line It is electrically connected, and the other end is electrically connected to the low-voltage contact wire.

For the parts that are not described in detail in the example of the active electronic price tag, please refer to the introduction above, and will not be repeated here.

The electronic price tag provided in the embodiments of the present application only has a certain number of contacts on the second surface, which has a small impact on the volume of the electronic price tag body. For the guide rail provided in the embodiments of the present application, the thickness of the positioning circuit board installed in the guide groove is small, and the volume changes little compared with the traditional guide rail; in addition, the circuit board is only equipped with simple resistors except for related wires. , The maintenance cost is lower in the later period. During use, after installing the electronic price tag into the rail slot, you can slide left and right to ensure that the electronic price tag is fixed at the mounting position provided by the rail, so that the contact point of the electronic price tag is electrically connected to the positioning detection circuit , The operation is simple and convenient.

The following takes the four-story shelf shown in FIG. 6 as an example to explain the implementation process of determining the placement position information of the commodity object in the embodiment of the present application.

First, the cloud server can obtain the identification information of the electronic price tag associated with the commodity object under the physical store.

When the staff associated with the physical store performs the display task, after determining the placement position of the commodity object, the commodity object and the electronic price tag can be bound, and the electronic price tag can be fixed in the position corresponding to the placement position of the commodity object In this way, consumer users can view the relevant information of the corresponding commodity object through the electronic price tag.

The shelf shown in Figure 6 can include 4 layers. On the beam corresponding to each layer, a guide rail for fixing the electronic price tag can be installed. After placing the commodity object on the layer, the electronic price tag card can be installed In the guide rail corresponding to the position of the commodity object, see the position relationship between the commodity object placed on the shelf and the associated electronic price tag as shown in FIG. 6 for details.

In the actual operation process, the operator can establish the association relationship between the commodity object and the electronic price tag through the price tag management device, and request the cloud server to deliver the relevant information of the commodity object to the associated electronic price tag for information display. The following takes the commodity object 1 in the physical store 1 as an example to illustrate the implementation process of binding an electronic price tag.

The operator in the physical store 1 can scan the barcode of the commodity object 1 and the barcode of the electronic price tag 131 through the price tag management device, and obtain the identification information of the two and submit it to the cloud server. Correspondingly, the cloud server can deliver the relevant information of the commodity object 1 (for example, commodity information, price information, inventory information, etc.) to the AP (Access Point, wireless access point) deployed in the physical store 1, and pass the AP The related information of the commodity object 1 is forwarded to the electronic price tag 131, and then the information is displayed on the display screen of the electronic price tag 131. In this way, the consumer user can view the relevant information of the commodity object 1 through the electronic price tag 131.

Similarly, it is also possible to bind the commodity object 2 and the electronic price tag 132, to bind the commodity object 3 and the electronic price tag 133, to bind the commodity object 4 and the electronic price tag 121, and to bind the commodity object 4 and the electronic price tag 121. 5 and the electronic price tag 122 perform binding processing, and perform the binding processing on the commodity object 6 and the electronic price tag 123.

In the above example, the cloud server can obtain the association relationship between the commodity object and the electronic price tag shown in Table 1 below.

Table 1

Secondly, the cloud server can obtain the voltage value information associated with at least one installation position that can be provided by the guide rail provided on the shelf, and the positioning detection circuit is provided at the installation position.

As described above, the guide rail in the embodiment of the present application may include at least one installation position, and each installation position may be provided with a corresponding positioning detection circuit, and each positioning detection circuit corresponds to a different voltage value. In this way, the electronic price tag is fixed After the guide rail, the voltage value corresponding to the location detection circuit at its location can be obtained and submitted to the cloud server, and the cloud server determines the specific installation location of the electronic price tag based on this.

For a single-layer shelf, a guide rail for installing an electronic price tag can be correspondingly configured, and the installation location information saved by the cloud server can include the identification information of the subdivided positions that the guide rail can provide. That is, the cloud server can determine where the electronic price tag is located on the guide rail based on the voltage value information.

For a shelf that includes at least two layers, at least two guide rails for installing electronic price tags can be correspondingly configured, and the installation position information saved by the cloud server can include the identification information of the shelf layer where the guide rail is located and the details that the guide rail can provide. Identification information of the sub-location. That is, the cloud server can determine which rail the electronic price tag is located on according to the voltage value information (in this example, the rail can be identified by the shelf layer where the rail is located, that is, the identification information of the shelf layer where the rail is located can be used as the identity information of the rail), And where the electronic price tag is located on the guide rail. Taking the schematic diagram shown in FIG. 6 as an example, the association relationship between the installation location information and the voltage value information stored in the cloud server can be shown in Table 2 below.

Table 2

Then, the electronic price tag can obtain the first voltage value information at its installation location and send it to the cloud server.

As described above, after the electronic price tag is fixed in the installation position provided by the guide rail, the positioning contact of the electronic price tag can be electrically connected with the positioning detection circuit set at the installation location, and the positioning contact can collect the installation location of the electronic price tag The first voltage value information of is transmitted to the processor, and then the first voltage value information is sent to the cloud server via the communication module.

As an example, the processor may periodically submit information to the cloud server through the communication module; or, may submit the information after obtaining an instruction issued by the cloud server for verifying the execution result of the display task. For example, the cloud server may issue instruction information to the electronic price sign when it is determined that the display task is completed.

In the embodiments of the present application, if the electronic price tag does not have remote communication capabilities, the command issued by the cloud server can be obtained through the AP, and the first voltage value information and the identification information of the electronic price tag can be submitted to the cloud server through the AP. As an example, if the communication module in the electronic price tag is a Bluetooth module, the processor may perform wireless communication with the AP through the Bluetooth module.

Finally, the cloud server can determine the target installation location information associated with the first voltage value information according to the association relationship between the installation location information and the voltage value information.

Specifically, after the cloud server obtains the information submitted by the electronic price tag, it can determine the target installation location of the electronic price tag according to the association relationship shown in Table 2, and can establish the relationship between the identification information of the electronic price tag and the target installation location information. connection relation.

Taking the electronic price tag 132 as an example, after the cloud server obtains the information submitted by the electronic price tag 132, according to the association relationship shown in Table 2, it can be determined that the electronic price tag 132 is located in the second subdivision of the guide rail set on the third shelf. Location; for the electronic price tag 122, after the cloud server obtains the information submitted by the electronic price tag 122, it can determine that the electronic price tag 122 is located at the second subdivision position of the guide rail set on the second shelf.

Understandably, the voltage value corresponding to the positioning detection circuit in Table 2 is usually a theoretical value. For example, for a 12V power supply, the voltage value 4 corresponding to the positioning detection circuit at the subdivision position 1 can be 3V, and the subdivision position The voltage value 5 corresponding to the location detection circuit at 2 can be 6V, and the voltage value 6 corresponding to the location detection circuit at the subdivision location 3 can be 9V. If the first voltage value obtained by the cloud server is 6V, it can be determined that the electronic price tag is located at the second subdivision position of the guide rail set on the third shelf.

In the actual application process, the actual measurement value of each positioning detection circuit may deviate from the theoretical value (for example, the first voltage value obtained by the cloud server is 6.5V, which does not match the voltage value information associated with the installation location) In order to ensure the accuracy of determining the target installation location information according to the first voltage value information, the embodiments of the present application may provide the following preferred solutions:

The electronic price tag can obtain the second voltage value information and submit it to the cloud server, where the second voltage value information may be the power supply voltage value of the electronic price tag. For passive electronic price tags, after the electronic price tags are fixed on the guide rails, the power contacts of the electronic price tags electrically connected to the high-voltage contact line can obtain the second voltage value information; for active electronic price tags, you can Obtain the output voltage of the power supply directly and use this as the second voltage value information.

Generally, when voltage jitter occurs, the fluctuation range of the voltage value of the high-voltage contact line and the voltage value of the divided-voltage contact line are the same, and the two change in proportion. Therefore, it can be based on the first voltage value information and the second voltage value information Determine the target installation location information. Specifically, the proportional value information associated with at least one installation position can be obtained, and the proportional value information is determined by the resistance value of the first resistor and the resistance value of the second resistor in the positioning detection circuit set at the installation position; If the first voltage value information does not match the voltage value information associated with the at least one installation position, a first ratio value is determined according to the first voltage value information and the second voltage value information; according to the at least one installation position The associated ratio value information determines the target installation location information associated with the first ratio value.

Taking the positioning detection circuit at the second subdivided position shown in Figure 1 as an example, the second voltage value is V _in , and the first voltage value V=R ₅ *V _in /(R ₂ +R ₅ ), both The ratio of is only related to _{the resistance values of R 2} and R ₅ , so the following ratio information can be obtained according to the resistance values of the two resistors: R ₅ /(R ₂ +R ₅ ), and establish the ratio information and the second The relationship between subdivision locations. In this way, after the cloud server obtains the first voltage value information and the second voltage value information, it can _{obtain the first ratio value through V/V in} , and determine the second subdivision location as the target installation location based on the above correlation. In this way, the measurement error problem caused by voltage jitter can be eliminated.

In summary, after the cloud server obtains the association relationship between the electronic price tag and the target installation location, it can determine the location information of the commodity object associated with the electronic price tag, and then perform the location information according to the legal display method information. Check, get check result information.

In the embodiment of this application, the legal display method information may be the general display method information configured uniformly for each physical store, which can be applied to all physical stores opened by the service provider; or, it may be a personalized display method configured for different physical stores Corresponding to this, the cloud server can obtain the legal display method information associated with different physical stores, and after determining the identification information of the target physical store to which the electronic price tag belongs, obtain the target legal display method information associated with the target physical store, and The placement position information of the merchandise object is compared, and the verification result information associated with the target physical store is obtained.

The following takes the electronic price tag 132 as an example to illustrate the implementation process of obtaining the verification result information by the cloud server.

The cloud server obtains the relevant information of the electronic price tag 132 associated with the physical store 1, which may specifically include the identification information of the electronic price tag 132 and the target installation location information of the electronic price tag 132 (in the above example, the target installation location information is set At the second subdivision position of the guide rail on the third floor), and at the same time, according to the association relationship shown in Table 1, it can be determined that the product object associated with the electronic price tag 132 is the product object 2, that is, the actual placement of the product object 2. The location is the third shelf, so that it can be compared with the legal display method information to obtain the verification result information.

For the placement position information of the commodity object, in addition to the shelf layer information, it may further include the specific placement position of the commodity object on the shelf layer. For example, in one way, the corresponding storage area can be divided for the shelf deck according to the subdivision position of the electronic price tag. In the above example, the layer 3 can be divided into three placement areas, and the placement position information of the commodity object 2 may be: the second placement area of the third shelf.

Or, in another way, the relative position relationship between the commodity objects can be determined based on the commodity objects placed on the same floor, so as to indicate the specific placement position of the commodity objects. In the above example, according to the relevant information of the electronic price tag 131 and the electronic price tag 133, the product objects adjacent to the left and right of the product object 2 can be determined, and the placement position information of the product object 2 can be: the third shelf, and the The merchandise objects placed on the layers are merchandise object 1, merchandise object 2, and merchandise object 3 in order from left to right.

Specifically, if the placement position information of the commodity object matches the legal display mode information, the correct placement verification result information can be obtained; otherwise, the incorrect placement verification result information can be obtained.

As an example, if in the legal display information, the commodity object placed at the second subdivision position of the third shelf is commodity object 7, then this example can obtain the verification result information of the incorrect placement of the commodity object. Send it to the terminal device associated with the physical store 1 for the operator to view. Preferably, the verification result information may include information about the incorrectly placed product object. For example, if the product object 2 on the third shelf is incorrectly placed, please adjust it to the product object 7. In this way, the operator can follow the verification result information It can quickly locate errors and help improve the efficiency of error correction.
