UWB technology-based positioning system architecture and positioning method thereof

Abstract

The invention relates to a UWB technology-based positioning system architecture and a positioning method, and the positioning system architecture comprises a UWB positioning tag which is arranged on a target needing to be positioned; several UWB positioning beacons fixedly arranged in a chemical plant area according to a preset rule, wherein each UWB positioning beacon comprises a battery used for supplying power, and the UWB positioning tag and the UWB positioning beacons are in wireless positioning communication through UWB signals so as to obtain position information of the UWB positioning tag relative to the UWB positioning beacons; a communication base station covering the positioning areas of the plurality of UWB positioning beacons and used for wirelessly receiving the position information of the plurality of UWB positioning labels in the coverage areas; and a positioning engine in communication connection with the communication base station and used for receiving the position information of each UWB positioning tag and carrying out position calculation on the position information so as to obtain the position coordinate of each UWB positioning tag. The positioning system architecture provided by the invention does not need wiring and is high in positioning precision.

Description

technical field [0001] The invention relates to the technical field of positioning in chemical plant areas, in particular to a positioning system architecture and a positioning method based on UWB technology. Background technique [0002] In the chemical industry, the production plant area is generally large. In order to ensure safe production and supervision requirements, it is necessary to accurately locate specific equipment or personnel. Usually, a chemical plant is divided into multiple areas according to the safety level. The safety protection level of different areas is different, and the requirements for positioning accuracy and safety regulations are also different. [0003] The existing Bluetooth positioning technology mainly uses a positioning method based on RSSI (Received Signal Strength Indication). The biggest problem is that the indoor environment is complex, and Bluetooth, as a 2.4GHZ high-frequency signal, will be greatly interfered. At the same time, in o...

Problems solved by technology

In this architecture, the positioning base station not only undertakes the positioning communication function, but also undertakes the data return function. Because of the large amount of positioning data and high power consumption, it is necessary to supply power and network through wired methods in practical applications, such as figure 1 The positioning base stations 1-4 shown are all connected to the positioning engine through wired connections, which brings great troubles to engineering applications

For the chemical industry scene, it is not convenient to lay wires in the dangerous area, which seriously hinders the promotion of UWB technology in the chemical industry
