Description

  The present invention particularly relates to an elevator crime prevention device that prevents an article in a building with an elevator from being illegally taken out.

  As a shoplifting prevention device for preventing so-called shoplifting for illegally taking out a product displayed in a store, for example, a technique disclosed in Patent Document 1 is disclosed.

  The technology described in Patent Document 1 configures a security gate by disposing a transmitter that transmits radio waves and a receiver that receives radio waves emitted from the transmitters at a predetermined interval, and the security gate is configured. A gate is installed in the vicinity of the store entrance and exit, and a resonance tag for unauthorized take-out discrimination that resonates with the radio wave is attached to a product in the store. That is, when the receiver detects a change in the received radio wave due to the product with the resonance tag passing through the security gate, the store clerk is notified by sounding a buzzer.

  Note that the above-described notification is not performed even if the accounting-processed product passes through the security gate because the clerk removes the resonance tag from the product during the predetermined accounting process.

Also, in some stores where elevators are installed, security gates are installed in the vicinity of elevator hall entrances to prevent items with resonant tags from being taken out to other floors by elevators.
JP 2003-109130 A

  In the technique described in Patent Document 1, it is only informed to the store clerk that a product with a resonance tag has passed the security gate, and cooperation or interlocking with the elevator is not taken into consideration. For this reason, shoplifters may escape to other floors using elevators, particularly in stores where elevators are installed.

  The present invention has been made in view of the above-described problems, and provides an elevator crime prevention device that prevents an article with a tag for unauthorized take-out determination from being illegally taken to another floor using the elevator. It is an object.

  The invention according to claim 1 is attached to an elevator having a car driven by a car driving means, an opening / closing door that is opened and closed by a door driving means, and opens and closes an entrance between the car and the landing. The detection means has a detection area in at least one of the vicinity of the elevator entrance and in the car, and includes detection means for detecting the presence of an unauthorized take-out discrimination tag attached to the article, wherein the detection means detects the presence of the tag. When detected, the movement of the passenger carrying the tagged item by the elevator is prevented by controlling at least one of the door opening / closing door driving means and the car driving means by the door driving means. Yes.

  Therefore, according to at least the first aspect of the present invention, even if a passenger carrying the tagged item moves to another floor by an elevator, the movement is prevented, and the passenger uses the elevator. Moving to another floor is prevented.

  More preferably, when the detection means is attached to the car as described in claim 2, it is not necessary to provide the detection means on each floor.

  Specifically, as described in claim 3, the detection means detects the presence of the tag in a car directly or indirectly, and when the passenger gets on and off, the detection means When the presence of the tag in the car is detected, the movement of the passenger carrying the tagged item by the elevator can be prevented by prohibiting the driving of the car by the car driving means.

  Specifically, as described in claim 4, when the detection means detects the presence of the tag in the car when passengers get on and off, the door drive means prohibits the door from being closed. The driving of the car by the car driving means is indirectly prohibited.

  Alternatively, as described in claim 5, when the detection means detects the presence of the tag in the car at the time of passenger getting on and off, the door drive means closes the door to close the elevator door. If the door drive means prohibits the door door from being opened, the passenger carrying the tagged item can stay in the car.

  More preferably, as described in claim 6, when the detection means detects the presence of the tag in the car when the passenger gets on and off, the detection means detects the presence of the tag in the car. When the elevator doorway is in the fully closed state with the same operation as when the door is not detected, the doorway can be fully closed without being recognized by the passengers carrying the tagged items. The escape of the passenger can be prevented.

  According to a seventh aspect of the present invention, the detection means has a detection area at the landing, and the detection means detects the presence of the tag at the landing of the floor where the car is stopped when passengers get on and off. When detected, if the door door is driven to close by the door drive means, the passenger with the above-mentioned tag is fully closed before entering the car, and the passenger is prevented from moving by the elevator. Can do.

  According to the first aspect of the present invention, even if a passenger who has the article with the tag attached tries to move by the elevator, the movement is prevented, so the article with the tag is used by using the elevator. It is possible to prevent illegal taking out to other floors.

  In addition, according to the second aspect of the present invention, there is no need to provide the detection means on each floor, which is advantageous in terms of cost.

  FIG. 1 is a front view showing an elevator car attached to a building having a store as a more specific first embodiment of the present invention. FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1 and 2 show a state where both the car side and landing side doorways are fully opened.

  As shown in FIGS. 1 and 2, a car side entrance 3 and a landing side entrance 4 are formed in the elevator car 1 and the landing 2, respectively. The entrances 3 and 4 are entrance doors, the car side doors 5 and the landings. It is opened and closed by the side door 6.

  The door opening / closing type is a so-called double-opening type, and the door driving device 9 serving as a door driving means drives the car-side door 5 to open and close based on a command from the door control unit 8 in the elevator control device 7. The side door 5 and the landing-side door 6 engaged with the car-side door 5 are opened and closed while being guided by the car-side sill 10 and the landing-side sill 11, respectively.

  As is well known, the car 1 is driven up and down by a hoisting machine 13 as car driving means that operates based on a command from the main control unit 12 in the control device 7. As a matter of course, the hoisting machine 13 is controlled by the main control unit 12 so that the car 1 cannot be driven up and down unless the car side entrance 3 and the landing side entrance 4 are fully closed.

  In addition, a columnar transmitter 14a and a receiver 14b are disposed opposite to each other on the car-side sill 10 with the car-side entrance 3 interposed therebetween, and a security gate 14 serving as a detecting means is configured by the transmitter 14a and the receiver 14b. Yes. The upper ends of the transmitter 14a and the receiver 14b are fixed to the car 1 with brackets 15 respectively.

  While the transmitter 14a has a built-in transmission antenna for transmitting a predetermined radio wave, the receiver 14b has a built-in reception antenna for receiving the radio wave. That is, when a resonance tag for unauthorized take-out discrimination that resonates with the radio wave exists between the transmitter 14a and the receiver 14b, the radio wave received by the receiver 14b changes as the resonance tag resonates with the radio wave. Therefore, the presence of a resonance tag between the transmitter 14a and the receiver 14b is detected with the change in the received radio wave. In other words, the security gate 14 has a detection area at the car-side entrance 3 and the security gate 14 detects the resonance tag passing through the car-side entrance 3 to indirectly detect the presence of the resonance tag in the car 1. To detect automatically. Note that the resonance tag is attached to a product or the like displayed in the store.

  Specifically, based on the received radio wave received by the receiver 14b, the determination processing unit 16 of the control device 7 connected to the receiver 14b determines whether or not there is a resonance tag in the car 1. That is, when the car 1 reaches the landing 2 and opens both the entrances 3 and 4, that is, when passengers get on and off, when the security gate 14 detects the resonance tag, the passenger who owns the product with the resonance tag is Judging that it was on board.

  FIG. 3 is a flowchart showing the processing contents of the control device 7.

  The control device 7 performs the process shown in FIG. 3 every predetermined interruption time when passengers get on and off, and controls the door driving device 9 based on the process.

  Specifically, first, the determination processing unit 16 checks whether or not there is a resonance tag in the car 1 (step S1). Here, when it is determined that the resonance tag exists in the car 1, a command is issued from the determination processing unit 16 to the door control unit 8 and the speaker control unit 17, and the door driving device 9 causes the car-side door 5 to be closed. While prohibiting (step S2), a predetermined sound is output from the speaker 18 (step S3). That is, the passengers who carry the product with the resonance tag by maintaining the fully open state of both the entrances 3 and 4 and indirectly prohibiting the raising and lowering of the car 1 by the hoisting machine 13 and sounding an alarm from the speaker 18 Notify the store clerk that he has boarded the basket 1. Therefore, the movement of the passenger by the elevator is prevented.

  Then, on the condition that a predetermined time has passed since the presence of the resonance tag in the car 1 is detected in step S1 (step S4), the door-closed drive prohibition state is canceled (step S5), and the speaker 18 Is stopped (step S6), and the normal operation state is restored.

  It should be noted that the crime prevention device does not operate as described above even if the accounting-finished product passes through the security gate 14 by removing the resonance tag from the product during the predetermined accounting process. Alternatively, the store clerk may perform a process of invalidating the function of the resonance tag during a predetermined accounting process.

  Therefore, according to the present embodiment, even if a passenger carrying a product with a resonance tag tries to move by an elevator, the movement is blocked. Can be prevented from being illegally taken to the floor.

  Further, since the security gate 14 is attached to the car 1, it is not necessary to provide the security gate 14 on each floor, which is advantageous in terms of cost compared to the case where the security gate 14 is installed on the hall 2 on each floor.

  4 and 5 are flowcharts showing a modification of the processing content of the control device 7 in the first embodiment.

  In the modified example shown in FIG. 4, when a crime prevention device is activated by detecting the presence of the resonance tag in the car 1 when passengers get on and off, a normal release state is restored by performing a predetermined release operation. (Step S7).

  Here, the release operation may be performed, for example, with an operation panel (not shown) provided in the hall 2, and is released into a cover with a lock among the operation panels (not shown) provided in the car 1. An operation switch may be provided.

  On the other hand, in the modified example shown in FIG. 5, when a passenger is getting on and off, if the crime prevention device is activated by detecting the presence of the resonance tag in the car 1, the resonance tag no longer exists in the car 1. In addition, the normal operation state is restored (step S8).

  In other words, when the passenger gets on and off, the resonance tag passes through the security tag 14, so that it is determined that the passenger carrying the product with the resonance tag is in the car 1, while the resonance tag passes again through the security gate 14. Therefore, it is determined that the passenger has got out of the car 1. In other words, shoplifting does not occur so frequently, so after detecting that the resonant tag has passed through the security gate 14 when passengers get on and off, when the resonant tag first passes through the security gate 14, Since it is very likely that the passenger carrying the product with the resonance tag has got out of the car 1, such a determination is made.

  Therefore, according to the above-described modification, it is possible to more reliably prevent the passenger from moving by the elevator in order to return to the normal driving state on the condition that the passenger cancels the operation or the passenger gets out of the car 1. There is a merit that can be.

  FIG. 6 is a flowchart showing a further modification of the processing content of the control device 7 in the first embodiment as the second embodiment of the present invention.

  In the second embodiment shown in FIG. 6, when the presence of a resonance tag is detected in the car 1 when passengers get on and off (step S1), the resonance tag in the car 1 is the same as in normal times. The car-side door 5 is driven to be closed by the door driving device 9 with the same operation as when the presence of the door is not detected, and the doors 3 and 4 are fully closed (step S9).

  Then, a command is output from the determination processing unit 16 to the main control unit 12, the door control unit 8, and the speaker control unit 17, and the elevator 1 is prohibited from being lifted and lowered by the hoisting machine 13 (step S10), and the door is driven. The opening of the car door 5 by the device 9 is prohibited (step S11), and a predetermined sound is output from the speaker 18 (step S12).

  In other words, while the passenger carrying the product with the resonance tag is in the car 1, the doors 3 and 4 are fully closed, and the car 1 is prevented from moving up and down, thereby preventing the passenger from moving by the elevator. And the passenger is kept in the car 1.

  Then, on the condition that a predetermined time has elapsed since the presence of the resonance tag in the car 1 was detected in step S1 (step S13), the door opening drive prohibition state is canceled and both the entrances 3 and 4 are fully opened. At the same time (steps S14 and S15), the car drive prohibition state is canceled (step S16), and the sound output from the speaker 18 is stopped (step S17), and the normal operation state is restored.

  Therefore, according to this Embodiment, while the movement of the said passenger by an elevator can be blocked | prevented, the escape of the passenger can be reliably prevented by making the said passenger stay in the cage | basket | car 1. FIG.

  In particular, after the passenger gets on the car 1, the doors 5 and 6 are closed in the same manner as normal and the doors 3 and 4 are fully closed. There is an advantage that both the entrances 3 and 4 are fully closed without being realized, and the passenger can be prevented from getting out of the car 1 during the door closing operation.

  7 and 8 are flowcharts showing a modification of the processing content of the control device 7 in the second embodiment.

  In the modified example shown in FIG. 7, when a crime prevention device is activated by detecting the presence of a resonance tag in the car 1 when passengers get on and off, a normal release state is restored by performing a predetermined release operation. (Step S18).

  As a release operation in this case, for example, an operation panel (not shown) provided in the hall 2 may be used.

  Further, in the modified example shown in FIG. 8, when a crime prevention device is activated by detecting the presence of a resonance tag in the car 1 when passengers get on and off, a predetermined release operation is performed or resonance occurs in the car 1. A normal operation state is restored on the condition that a predetermined time has passed since the presence of the tag was detected (steps S19 and S20).

  Therefore, in the modified example, substantially the same effect as in the second embodiment can be obtained.

  FIG. 9 is a front view showing an elevator car according to a third embodiment of the present invention.

  In the third embodiment shown in FIG. 9, a transmission / reception mat 19 is provided as detection means on the floor surface of a car, instead of the security gate 14 in the first embodiment. The transmission / reception mat 19 has a detection area in the car 1 and wirelessly communicates with an IC tag attached to a product or the like displayed in the store instead of the resonance tag in the first embodiment. The presence of the IC tag in the car is directly detected. The transmission / reception mat 19 is connected to the control device 7 as in the first embodiment.

  And also in this 3rd embodiment, when the IC tag in the car 1 is detected at the time of passenger getting on and off, as in the first embodiment, the passengers who carry the goods with the IC tag. By preventing the movement by the elevator, it is possible to obtain substantially the same effect as in the first embodiment and to directly detect the IC tag in the car 1, so that the IC in the car 1 can be detected. There is an advantage that the presence of the tag can be detected more accurately.

  FIG. 10 is a view showing a fourth embodiment of the present invention, and is a front view showing an elevator car.

  In the fourth embodiment shown in FIG. 10, in place of the transmission / reception mat 19 in the third embodiment, a transmission / reception antenna 20 is provided on the indoor ceiling of the car 1 as detection means. The transmission / reception antenna 20 has a detection area in the vicinity of the landing side entrance 4 of the landing 2 and is connected to the control device 7 as in the first embodiment.

  FIG. 11 is a flowchart showing the control contents of the control device 7 in FIG.

  In the fourth embodiment, when the presence of an IC tag is detected at the hall 2 when passengers get on and off (step S21), the main control unit 12, the door control unit 8 and the speaker control unit 17 are notified from the determination processing unit 16. A command is output, both the entrances 3 and 4 are fully closed (S22), a predetermined sound is output from the speaker 18 (step S23), and the car 1 is moved to the first floor in the traveling direction with the hoisting machine 13. Move (step S24).

  Then, the audio output from the speaker 18 is stopped (step S25), both the entrances 3 and 4 are fully opened (step S26), and the normal operation state is restored.

  That is, when a passenger carrying an article with an IC tag tries to get into the car 1, the car 1 moves by closing both the entrances 3 and 4 before the passenger gets into the car 1, The passenger is prevented from moving by the elevator.

  Therefore, according to the fourth embodiment, by not allowing the passenger to get on the car 1, it is possible to prevent the passenger from moving by the elevator without inconvenience the general passenger on the car 1. .

  In the first to fourth embodiments described above, the present invention is applied to an elevator with a door opening / closing type having two doors, but it goes without saying that the present invention can be applied regardless of the door opening / closing type.
