A rfid-based gun position determination system

Abstract

An RFID-based gun position judging system comprises an off-normal detection module, a tracking and positioning module and an information processing module. The off-normal detection module comprises an electronic label sub-module for periodically sending first information, and a positioning card-reader sub-module for receiving the first information sent by the electronic label sub-module. The tracking and positioning module comprises a plurality of tracking card-reader sub-modules for receiving the first information sent by the electronic label sub-module. The information processing module receives second information sent by the positioning card-reader sub-module to judge whether a gun is off normal, and receives fifth information sent by the tracking card-reader sub-modules to judge the moving path and orientation of the off-normal gun. By means of the system, whether a gun is off normal can be rapidly detected, and the off-normal gun can be rapidly tracked and found back, so the system has good technical prospects.

Description

technical field [0001] The invention belongs to the field of RFID applications, in particular to an RFID-based position determination system. Background technique [0002] In recent years, shooting incidents have occurred frequently in various countries, which has brought harm to people's personal safety and social stability. Police guns are a special tool to deter crime. If the police guns are not properly supervised and the police guns are lost, it will bring major security risks to the country and society. solved problem. When the police gun is out of position, how to quickly detect the out-of-position situation at the first time and call the police in time, and how to locate and track the out-of-position gun will play a decisive role in quickly recovering the out-of-position gun. [0003] At present, the relatively mature positioning and tracking technology includes GPS (Global Positioning System) global satellite positioning technology. Through GPS terminals, transmis...

Problems solved by technology

However, there are many difficulties in applying GPS to the out-of-position detection and positioning tracking of guns. First, the out-of-position detection of guns requires a relatively small detection distance range, and the positioning accuracy of GPS positioning technology cannot meet the requirements.

Secondly, using GPS positioning satellite technology to locate and track out-of-position guns needs to directly install GPS terminal devices on police guns, which not only requires the cooperation of corresponding software, but also leads to high costs, and its large size, which will increase the cost of installation in police guns. The size and weight of the gun, the high power consumption, and the need to replace the battery frequently all make it inconvenient to use the gun
