Embodiment Construction
[0056] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0057] figure 1 A system architecture diagram of an embodiment of the present invention is given, wherein multiple positioning terminals LE access the communication network S101 through the wireless link S103 and then establish a communication connection with the positioning management platform S102, and the positioning management platform S102 collects the positioning information reported by each LE. The measurement information is combined with the terminal historical trajectory information in the database and the positioning algorithm to determine and record the current position of each LE; at the same time, the positioning terminal LE and the positioning mark LM automatically form a mesh wireless sensor network through the short-distance wireless link S104, in which The LE at the gateway position collects the status information of each node...
