Description

A shopping guide method and system based on indoor and outdoor positioning

technical field

The invention relates to the technical field of indoor and outdoor positioning, in particular to a method and system for guiding commodity shopping based on indoor and outdoor positioning.

Background technique

With the gradual maturity of indoor positioning technology, some large indoor places (such as airports, shopping malls, exhibition halls, etc.) have provided indoor positioning and navigation software, generally in the form of APP software, and users can locate themselves in real time after downloading through smart terminals. It can also quickly query the designated location in the venue for navigation, helping users reach their destination quickly.

Indoor positioning technology is very different from outdoor positioning technology. The outdoor positioning technology uses the GNSS module, which needs to receive more than 4 satellite positioning signals, and uses the pseudo-range positioning method of the signal arrival time to realize the 3D positioning of the terminal; while the current indoor positioning technology in the public domain generally uses WLAN positioning technology, through the Wi-Fi module Or bluetooth module, receive the WLAN signal of more than 3 APs, adopt three sides or realize 2D or 2.5D (distinguish floor) positioning. When the user transitions from outdoor to indoor to complete the switching of indoor and outdoor positioning systems, due to problems such as incomplete indoor map information, it takes a long time to search and download through the wireless communication network, which will lead to poor user experience.

However, the current indoor navigation technology generally only points out the specific store location to the user. After the user arrives indoors, he still does not know which store the product he wants to buy is located, causing the user to spend more time searching for the product.

Contents of the invention

Based on the above situation, the present invention proposes a commodity shopping guide method based on indoor and outdoor positioning. One or more wireless hotspot APs (base stations) are installed at the entrance of the outdoor (outside the shopping mall) and periodically send detection signals outward. If it is detected that a user terminal (that is, a mobile terminal) enters the radiation range of the base station, a connection is established with the user terminal. After the mobile terminal obtains the required product information, it requests the wireless hotspot AP to download the indoor map, so that the user can cache the indoor map in advance and obtain the store location corresponding to the corresponding product information. After entering the room, the outdoor positioning system can be combined with the map for positioning and shopping guide, which improves the user experience.

A commodity shopping guide method based on indoor and outdoor positioning includes the steps of: setting a wireless hotspot at an outdoor preset position, detecting whether there is a mobile terminal within the radiation range of the wireless hotspot; if so, requesting to establish a connection with the mobile terminal; obtaining the commodity input by the user information and send the indoor map to the mobile terminal; obtain the corresponding store location information in the indoor map through the commodity information.

Further, the outdoor coordinate information of the mobile terminal is obtained according to the outdoor positioning technology, and then the indoor coordinate information of the mobile terminal is obtained according to the wireless hotspots set at the different preset positions, and the outdoor coordinates are compared with the indoor coordinate information. Coordinates are matched.

Further, after receiving the indoor map package, the mobile terminal switches the outdoor positioning technology to the indoor positioning technology, and uses the indoor coordinates corresponding to the outdoor coordinates as the starting point of the indoor map.

The present invention also provides a commodity shopping guide system based on indoor and outdoor positioning, which is characterized in that it includes: a wireless detection connection module and a mobile terminal; the wireless hotspot is connected to the mobile terminal through a wireless signal; the mobile terminal includes a data processing module , a data storage module, and a display interaction module; the wireless detection connection module is to set a wireless hotspot at an outdoor preset position, and is used to detect whether there is a mobile terminal within the radiation range of the wireless hotspot, and if so, request to establish a connection with the mobile terminal; obtain the user The input commodity information and send the indoor map to the mobile terminal; the display interaction module is used to obtain the commodity information input by the user and display the indoor map information in the data storage module; the data processing module is used to obtain the described commodity information through the user input The corresponding store location information in the indoor map; the data storage module is used to receive the indoor map sent by the wireless detection connection module.

Compared with the prior art, the present invention is simple to operate, can cache indoor maps in advance, and obtain the store location corresponding to the corresponding product information, and can directly locate and guide the shopping with the outdoor positioning system combined with the map after entering the room, which improves the user experience .

Detailed ways

The solution of the present invention will be described in detail below in combination with the preferred embodiments thereof.

As shown in Figure 1, the method in this embodiment includes steps:

S101: Set up a wireless hotspot at an outdoor preset location, and detect whether there is a mobile terminal within the radiation range of the wireless hotspot; if so, go to S102.

At present, in public places, such as railway stations, airports, parking lots, shopping malls, coffee shops, museums, libraries and other places, the demand for indoor navigation applications is also increasing day by day. Since Wi-Fi modules and Bluetooth modules have become the standard configuration of smart phones, Wi-Fi positioning and Bluetooth positioning have become the best choice for indoor positioning technology. However, these public places generally only install corresponding signal transmission devices indoors, so that users can only perform positioning when they enter the room. In this embodiment, a signal transmitting device (such as a Wi-Fi wireless hotspot, Bluetooth iBeacon) is installed outdoors in a corresponding public place, and the signal transmitting device is used to detect whether the mobile terminal is within its radiation range.

S102: Request to establish a connection with the mobile terminal; acquire commodity information input by the user and send an indoor map to the mobile terminal.

As shown in Figure 2, when the wireless hotspot detects the mobile terminal, it will request to establish a connection with it. After receiving the request, the user may determine whether to connect to the wireless hotspot and receive data; or the user may set the mobile terminal to automatically connect to the wireless hotspot and receive data. At this time, if the user is going to enter the indoor (such as a shopping mall) for shopping, he can accept the connection request and input the information of the product he wants to buy, and request to download the indoor map of the place. The mobile terminal will detect whether the current indoor map data has been entered, and if so, it can directly call the map package data. If not, request the wireless hotspot to download the indoor map package data. Through such an operation, users can download indoor maps in advance when they are close to indoors (such as shopping malls), and do not need to enter indoors to download maps.

In addition, users often use positioning technologies such as GPS and Beidou outdoors. When the user enters the room, the indoor positioning technology is used, and the switching between the two positioning technologies requires a data preparation process, so that the user will obviously feel the time delay. And adopting the method of the present invention to pre-download the map package can enable the user to use the indoor map data before entering the room.

Since some users may just pass through the outdoor area and are not ready to enter the room, at this time it is necessary to judge whether they are ready to enter the room based on the user's historical trajectory. Therefore, outdoor APs are generally installed at the entrance to the room, such as the entrance of a shopping mall or a garage. If the user can receive signals from more than two wireless hotspot APs at the same time when entering the room, the current location of the mobile terminal can be calculated by knowing the distance between the two APs and the distance between the two APs and the mobile terminal in advance. Of course, if three or more APs are set at different preset positions, the accuracy of locating the mobile terminal can be enhanced.

As shown in Figure 3, what this embodiment adopts is that the second wireless hotspot AP2 is indoors, which is more conducive to judging whether the mobile terminal enters the room; during implementation, some wireless hotspots can be set outdoors. If multiple APs are set at the location, the scope of indoor positioning can be greatly extended to outdoors. When the mobile terminal enters the first wireless hotspot AP1 and the second wireless hotspot AP2, the distances between the mobile terminal and AP1 and between the mobile terminal and AP2 can be known according to the radiation intensity and the time information of sending and receiving, and AP1 and AP2 pass through the first preset position and the second preset position to find the distance between them. Through this method, it can be obtained that the mobile terminal is at point A outdoors and at point B indoors. Due to the indoor coordinates of point B, when the mobile terminal does not enter the room, it can be automatically screened out by the algorithm.

Similarly, according to the wireless hotspots at three different preset positions, the position of the mobile terminal when it enters the room can be calculated more accurately.

After that, the system can judge whether to enter the room by using the current location of the terminal and the matching situation of the electronic map. For example, when a user moves from outdoors to indoors, after the user's location passes the entrance, the outdoor positioning technology can be switched to the indoor positioning technology, and after obtaining the indoor coordinate information of the mobile terminal, the outdoor coordinate information and the indoor coordinate information are matched and compared. to display.

As a more optimal implementation example, after the mobile terminal receives the indoor map package, it can switch the outdoor positioning technology to the indoor positioning technology, obtain the outdoor coordinate information of the mobile terminal according to the outdoor positioning technology, and then according to the different preset positions The set wireless hotspot obtains the indoor coordinate information of the mobile terminal, and associates the outdoor coordinates with the indoor coordinates (that is, one-to-one correspondence between the indoor coordinate system and the outdoor coordinate system adopted by it). And use the indoor coordinates corresponding to the outdoor coordinates as the starting point of the indoor map. Since the user agrees to download the map and input keyword information, it can be concluded that the user will definitely enter the place, and at this time, there is no need to make a room entry judgment.

S103: Obtain corresponding store location information in the indoor map through the commodity information input by the user.

Indoor electronic maps generally include the name and location information of the indoor store. At present, it is difficult for most customers to know what the store is selling simply by the name of the store. They often go to the actual store to see whether they have their own desired commodity. This will cause users to waste a lot of time looking for stores. In this embodiment, the shop (or office) in the indoor map contains the product information (service content) it sells. When the user enters the product information through the mobile terminal, the indoor map can search for the shop that sells the product, and obtain these The name and location information of the store is displayed by calling the indoor map. At the same time, a navigation route can be generated to guide the user to the store.
