And performing position display on the equipment end of the user terminal by using the obtained search result of the text information input by the book equipment and simultaneously associating the WIFI information of the nearest access point with the equipment information of the corresponding keyword. And adding latest access point information in the retrieval of the WIFI section of the user, thereby realizing the position information of the nearest department of the user equipment and improving the management and use efficiency of the equipment. For example, when a user queries a mobile B-mode ultrasound device, the user directly uses the access information of the B-mode ultrasound device as an assistant, and then may obtain the movement trajectory information of the mobile device according to the access log movement information of the device, and perform display in a display graph of a WiFI access point of a hospital.

In the access information of the network management equipment, access clock information is introduced for inquiry so as to ensure the deduplication and positioning processing of the managed medical equipment and record the accessed clock information. Therefore, the information of the wireless access point time needs to perform a synchronization process.

In order to realize synchronization of time access time information and guarantee conflict and error of information of time of each WIFI access point, clock synchronization needs to be realized for each WIFI access point, and clock synchronization between subnet positioning monitoring management devices (namely, each WIFI access point) in a subnet is as follows: the subnet master node periodically broadcasts local clock information to WIFI access nodes of other subnets of the subnet where the subnet is located, the information of the WIFI access nodes of the other subnets can be only stored in the subnet master node, and clock distance adjusting information of the WIFI access nodes of the other subnets is added into a broadcast packet sent by the subnet master node, so that the WIFI access nodes of the other subnets can conveniently adjust synchronous clock deviation. And the WIFI access nodes of other subnets monitor the clock synchronization information of the master node and adjust the deviation of the latest received clock information according to the known physical distance between the WIFI access nodes and the master node of the current subnet, so that all the positioning monitoring nodes in the same subnet have a synchronous clock.

And the MAC address of the target medical equipment to be positioned is recorded into a remote server, and is broadcasted and sent to all positioning monitoring nodes in the Wi-Fi Internet of things through various levels of subnets. And the positioning monitoring node locally maintains an MAC address table of the target equipment to be positioned and periodically updates the list through the subnet master node.

Optionally, only one WIFI access point serving as a subnet gateway, that is, a master node, is provided in one subnet, and one gateway may manage multiple controllers. One controller controls a plurality of passive RFID readers or intelligent devices in a wired connection mode; a passive RFID reader-writer controls a plurality of single antennas, array antennas, sensors and acousto-optic equipment through a read-write module. Therefore, a background management system in the server controls a plurality of subnet gateways, one subnet gateway controls a plurality of controllers, one controller controls a plurality of reader-writer/intelligent equipment, and one reader-writer controls a plurality of antennas and sensors, so that an internet of things system which can be expanded infinitely but can be managed limitedly is formed step by step.

Alternatively, when many reader/smartdevices support ethernet communications and support standard command control modes, these passive RFID readers and smartdevices may not access the subnet gateway indirectly through a controller or other edge middleware, but rather directly connect to the subnet gateway. They are controlled by the subnet gateway through instructions.
