Problems solved by technology

[0005] The present invention aims at the large range of mobile base station positioning area in the prior art, and the accuracy is relatively poor. It can only locate near a certain base station, which is related to the deployment density of mobile base stations. The positioning accuracy is generally more than 50 meters; GPS cannot effectively locate the height, and the positioning accuracy is relatively low. Inferior disadvantages, providing a mobile terminal positioning technology based on Internet of Things perception technology

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)...

Abstract

The invention discloses a positioning system and method based on mobile internet technology and internet of things technology based on an internet positioning method based on internet of things sensing. The internet positioning system based on internet of things sensing comprises radio frequency identification tag units (1), an internet of things locator(2), and a GIS server(3); the positioning method comprises the following steps: determining radio frequency identification tags (11) in a region, and distributing a global unique radio frequency identification code ID for each radio frequency identification tag (11), wherein each radio frequency identification tag unit (1) is received by a plurality of internet of things locators (2) Xi(Xi, i=1,...n), ranking RSSI numerical values of the radio frequency identification tag (11) signals RSSIi(RSSIi, i=1,...n) received in the region range; and determining whether to bind the internet of things location. Based on the internet of things positioning technology, the internet of things locator is used for receiving and sending the signal of the radio frequency identification electronic tag; the personnel can be effectively positioned and monitored in real time, and the positioning method has features of being accurate, convenient and fast in positioning.

Description

technical field [0001] The present invention relates to the radio frequency identification technology of the Internet of Things and the Internet positioning technology, and in particular to an Internet positioning system and method based on the perception of the Internet of Things. Background technique [0002] At present, RFID technology is the abbreviation of Radio Frequency Identification, that is, radio frequency identification technology, which is a technology that uses radio frequency signals to realize non-contact information transmission through space electromagnetic coupling and achieve object identification through the transmitted information. RFID technology has been widely used in personnel location monitoring. The use of RFID technology can effectively monitor the real-time positioning of personnel, providing a certain degree of personnel security. [0003] At present, the positioning technology based on mobile terminals on the market mainly adopts the mobile b...
