The invention provides an indoor object positioning system and a method thereof. A radio frequency identification reading tag is configured on a tracked object; an ultra-wideband tag is configured on each wireless radio frequency reader; a plurality of wireless radio frequency readers and a plurality of ultra-wideband positioning devices are configured in an indoor environment; the ultra-wideband positioning devices position the wireless radio frequency readers in the indoor environment according to the ultra-wideband tags; after a control center obtains the positioning of each wireless radio frequency reader in the indoor environment by each ultra-wideband positioning device, when each wireless radio frequency reader reads a first unique identifier, the tracked object is subjected to same tracking on the basis of the positioning of each wireless radio frequency reader in the indoor environment, and therefore, an indoor object positioning technical efficiency that positioning accuracy is improved and the indoor object still can be positioned although the indoor object is shaded can be achieved.
Description
technical field [0001] The present invention relates to a positioning system and its method, in particular to a positioning system and its method for indoor objects using radio frequency and ultra-wideband technology. Background technique [0002] Traditional indoor object positioning systems mainly use the following methods: [0003] One is a positioning technology based on the RSSI (Received Signal Strength Indication, RSSI) principle, which can use Zigbee, BlueTooth, etc. of 2.4G technology. [0004] One is a time-of-flight based positioning technology, usually using a UWB (Ultra-wideband, UWB) based positioning model. [0005] The anti-occlusion based on 2.4G RSSI is better than UWB, but the positioning accuracy is poor. The UWB-based solution is vulnerable to occlusion, and has a high cost and a large volume. [0006] To sum up, it can be seen that the existing indoor object positioning methods have long existed in the existing indoor object positioning accuracy and ...
