Abstract

The invention discloses a low-power-consumption radio frequency identification positioning system and a method thereof. Through ingenious design of a piezoelectric sensor technology and a low-power-consumption control circuit, the power consumption of the whole system is reduced to the maximum extent, the system can stably and reliably work for a long time by adopting batteries. Information transmission between the system and server background equipment is in wireless communication through a WIFI module, and finally, the installation of system equipment is wire-free. The invention is especially suitable for wire-free deployment of decorated indoor places, does not need to decorate the decorated indoor environment again, reduces the reconstruction cost to the maximum extent, and shortens the deployment period to the maximum extent. A piezoelectric sensor device is deployed at a key position needing to be positioned indoors, and the specific positions of the piezoelectric sensor device and the key position can be determined in combination with a patent background management platform processing system.

Description

technical field [0001] The invention relates to the technical field of radio frequency positioning, in particular to a low-power radio frequency identification positioning system and a method thereof. Background technique [0002] Indoor is the most closely related place of human life. A large number of human application requirements are related to indoor positioning services, such as the storage location of indoor objects, the location of people, and so on. [0003] At present, mature indoor positioning technologies mainly include Bluetooth, WiFi / WLAN, radio frequency identification (RFID), and ultra-wideband (UWB). Among them, both Bluetooth and WLAN technologies judge the distance based on the value of the received signal strength indicator (RSSI) of electromagnetic waves, and calculate the position through the distance to multiple base stations, so as to achieve the purpose of positioning. This technology has a high cost (at least four Only one base station can be posi...
