Provided in an embodiment of the present invention are a positioning method, a device, a system, equipment, and a storage medium. The invention relates to the technical field of spatial positioning. The method comprises the steps of obtaining the sending time of three wireless fidelity (WiFi) probes for sending a detection signal and the receiving time of three wireless fidelity (WiFi) probes for receiving a response signal, the response signal being a signal returned by a WiFi device receiving the detection signal, and calculating the distance between the WiFi equipment and each WiFi probe in the three WiFi probes according to the obtained sending time and receiving time and a preset WiFi signal propagation rate, and determining the positioning position of the WiFi equipment according to the calculated distance and the position information of the three WiFi probes. Therefore, when the scheme provided by the embodiment of the invention is used for positioning, the accuracy of positioning the WiFi equipment can be improved.
Description
technical field [0001] The present invention relates to the technical field of spatial positioning, in particular to a positioning method, device, system, equipment and storage medium. Background technique [0002] A WiFi (Wireless Fidelity, Wireless Fidelity) device is an electronic device capable of WiFi connection, such as a mobile phone, a tablet computer, a notebook computer, and the like. In order to manage WiFi devices and users holding WiFi devices in a certain area, it is usually necessary to locate the WiFi devices in the area. [0003] In the prior art, a positioning device usually uses a WiFi probe to locate a WiFi device. Specifically, the WiFi probe can send a detection signal, and the WiFi probe generally has a certain working range, and the detection signal propagates within the above working range. When the WiFi device enters the above-mentioned working range, it can receive the detection signal and send a response signal to the WiFi probe, and the WiFi pr...
