The current problems encountered by the exhibition hall:
With the rise of LBS (location-based services) and subsequent applications in all aspects of life and travel, the new experience brought by LBS is obvious, fresh, three-dimensional, and spatial, which makes travel changes bit by bit. It is vivid and vivid. The exhibition hall also wants to take the ride of LBS and become an intelligent and vivid exhibition hall. Therefore, the exhibition hall urgently needs to know the real-time location information of customers, and guide customers on this basis.
However, the conventional LBS services are all outdoors, and they are GPS-based outdoor positioning. Indoors, GPS does not work. How to perform accurate real-time positioning in the exhibition hall?
solution
Suzhou Youpin Technology’s Wi-Fi-based real-time positioning system can completely improve the current situation of the exhibition hall and provide intelligent guide services based on Wi-Fi real-time positioning. We use the existing Wi-Fi system in the exhibition hall to achieve real-time positioning without the need for additional network deployment. The navigation service system consists of Wi-Fi handheld terminals (PDAs, smart phones, etc.), wireless local area network, positioning server and content server.
After receiving the signal, the wireless locator (AP) transmits the signal to the positioning server. The location server judges the location of the person based on the strength of the signal, and displays the specific location through the electronic map. The content server obtains the location information of the relevant person from the location server, and combines it with nearby booths to push booth information or provide customers with target navigation information .
System composition
The Wi-Fi positioning and navigation system is composed as follows:
1) Wi-Fi Handheld Terminal (Handheld Terminal)
The handheld terminal can be a PDA or a smart phone, and the APP of the exhibition hall can be downloaded and installed on the terminal.
2) Wireless LAN
The wireless local area network is composed of APs. AP is divided into communication AP and positioning AP. Communication AP provides data transmission function, which can cover every point. Huawei AP is used here in Wuhan. Our system is fully compatible with the original equipment.
3) Locating Server
The positioning server contains a positioning engine that can calculate the position based on the signal.
4) Content Server
The content server supports information content related to the exhibits and user information
Realize the function
1) Real-time monitoring
• The icon displayed on the map corresponds to the real-time position of the PDA terminal;
• Real-time monitoring of the PDA terminal, and display the current location of the handheld PDA on the map;
• After clicking the icon, the detailed information of the PDA can be displayed;
• The designated PDA terminal can be tracked, and the map will automatically switch with the movement of the PDA;
2) Track playback
• Replay the customer’s trajectory in the exhibition hall;
• Judge the length of time a customer stays at a certain booth and determine the customer’s focus;
3) Navigation function
• The location of the user can be displayed through the positioning function of the PDA device, and the user can locate a certain type of booth, the specific location of a certain booth through the PDA query function, and provide services through route guidance;
4) Information promotion
• When the locator locates the user to a certain booth, the content server sends the relevant booth information to the user’s PDA through the WIFI network to achieve the purpose of pushing information at a fixed point;
Advantages of WiFi real-time positioning system
1) Wireless local area network is very popular, cheap, easy to build and manage; wireless local area network can also be used for other purposes such as wireless Internet access, voice, video, etc.;
2) Real-time personnel positioning, you can find the location of a person at any time, and the path passed in a certain period of time, and display the line trajectory;
3) High positioning accuracy, up to 3-5m (depending on the specific environment), accurately grasp the location of personnel;
4) Ultra-low power consumption, if the power saving mode is adopted, the battery life can be up to 1 year, the label battery can be replaced, and the rechargeable battery can also be used, which is safe to the human body and has no radiation damage;
5) The visual terminal platform displays the location and movement track of the personnel in the form of an electronic map, and can also display the temperature alarm information of the surrounding environment, which is convenient for environmental monitoring and safety precautions.
Wireless broadband has strong scalability. The bandwidth of the Wi-Fi wireless network has reached several hundred megabytes, which can realize multiple functions such as voice, video, positioning, and wireless sensing. Moreover, the network has strong compatibility, supporting WiFi mobile phones/interphones, notebooks/tablets, etc., providing a basic wireless network for the prison to realize mobile office and mobile security, avoiding repeated investment in the future.
At present, the “WiFi real-time positioning system” has been operating stably in an exhibition hall in Wuhan, and its practicability and innovation have been highly affirmed by colleagues and users in the industry!
