Embodiment 1
[0021] Target positioning system based on WiFi probe, such as figure 1 Shown: It includes multiple mobile terminals, multiple WiFi probes and multiple detection terminals. The WiFi probe detects the mobile terminal and sends connection data. The mobile terminal can be an existing mobile terminal or tablet terminal, etc. The mobile terminal passes the WiFi protocol. Wireless communication with WiFi probes, WiFi probes are located on different floors, the detection end corresponds to the WiFi probe one by one, that is, each WiFi probe is equipped with a detection end, and when the detection end is located on the bottom floor or the top floor, the initial floor information.
[0022] The detection end includes a detection module, a communication module and a processing module. The detection module obtains the connection data of the corresponding WiFi probe and the vertically upward adjacent floors and sends it to the processing module. The detection module can be electrically conn...

The invention relates to the technical field of indoor position management, in particular to a WiFi probe-based target positioning system, which comprises a plurality of mobile terminals, a pluralityof WiFi probes and a plurality of detection terminals, and is characterized in that the WiFi probes detect the mobile terminals and send connection data, the detection terminals are in one-to-one correspondence with the WiFi probes, and each detection terminal comprises a detection module and a processing module; the detection module obtains the connection data of the corresponding WiFi probe andthe vertically upward adjacent floor and sends the connection data to the processing module, the processing module identifies azimuth angle information in the connection data, and the processing module identifies the WiFi probe of the adjacent floor in the vertical direction according to the azimuth angle information; and the processing module identifies the strength information of the mobile terminal in the connection data of the WiFi probe of the adjacent floor, judges the floor position of the WiFi probe according to the received initial floor information when the strength information is greater than the preset strength, and judges the position information of the mobile terminal according to the strength information and the floor position. According to the invention, the positioning accuracy of the target in the vertical direction in the high-rise building can be improved.
Description
technical field [0001] The invention relates to the technical field of indoor position management, in particular to a target positioning system based on WiFi probes. Background technique [0002] Positioning is to record and track the real-time position of the target. At present, the most commonly used is GPS (Global Positioning System), which can accurately locate the target. However, with the acceleration of urbanization, the number of high-rise buildings has also increased. The positioning effect and accuracy of GPS positioning are very poor when the target enters the room. For users who want to locate indoor targets, it is almost impossible to locate the target through GPS positioning. [0003] In order to solve the existing problems of indoor GPS positioning, the publication number CN109769208A discloses a method for realizing indoor positioning and navigation inside a station, including a) setting a station map area, drawing an electronic map of the station, and storin...
