Embodiment 1
[0025] Internet positioning system based on IoT perception, such as figure 1 As shown, it includes a radio frequency identification electronic label unit 1, an Internet of Things locator 2, and a GIS server 3;
[0026] The radio frequency identification electronic tag unit 1 includes more than one radio frequency identification electronic tag 11, and the radio frequency identification electronic tag 11 periodically transmits a wireless broadcast signal with a radio frequency identification code;
[0027] The Internet of Things locator 2 includes a radio frequency reader 21 and a gateway 22;
[0028] The radio frequency reader 21 is used to receive the wireless broadcast signal transmitted by the radio frequency identification electronic tag 11, and the gateway 22 and the GIS server unit 3 perform data transmission through wireless wifi or mobile communication technology 2G\3G\4G network. The present invention is suitable for occasions where GPS cannot be positioned accurately...
Embodiment 2
[0033] The Internet positioning method based on Internet of Things perception includes the above-mentioned Internet-based positioning system. After receiving the data sent by the Internet of Things locator 2, the GIS server 3 performs positioning by the following methods:
[0034] ①. Assign a location to each IoT locator (2) X i (Xi, i=1, … n), and assign a globally unique RFID fixed ID to each RFID tag (11);
[0035] ②, RSSI sorting: The signal of the radio frequency identification tag (11) received by the IoT locator (2) within the selected area is the signal RSSIi (RSSIi, i=1, ... n), sorted according to the signal strength;
[0036] ③. Path planning: plan the positioning path according to the actual road strength passed by the radio frequency identification tag unit (1), filter the radio frequency identification tag unit (1) received by the IoT locator (2) according to the actual path; judge the received signal Whether the radio frequency identification electronic tag (11)...
