Abstract

The invention discloses a wireless positioning monitoring system and method based on a UWB technology. The system comprises a single base station; an antenna array; a radio frequency module, a monitoring service station, and a label which are connected with the antenna array; an acquisition module and a display screen connected with the label; the acquisition module comprises a far infrared metering module, an air volume and wind speed sensor, a methane gas sensor, and a PM2.5 dust sensor; the antenna array, the monitoring service station and the label are respectively connected with the single base station. A single base station synchronization header is used for time synchronization of the label with the time before positioning the single base station; the single base station with an antenna is used for measuring the distance and angle between the label and the single base station through a TOA positioning technology and an AOA positioning technology, thereby obtaining a three-dimensional position of the label; the detected information is transmitted to the monitoring service station via the acquisition module through the single base station; if the information value of a dangerous linkage source exceeds a normal range value, the system performs an alarm. The wireless positioning monitoring system and method based on the UWB technology in the invention have the advantages oflow power consumption, anti-interference, low complexity, high transmission efficiency and accurate positioning.

Description

technical field [0001] The invention relates to the technical field of UWB positioning monitoring, in particular to a wireless positioning monitoring system and method based on UWB technology. Background technique [0002] With the continuous deepening of the research and application of the Internet of Things, wireless communication technology will develop rapidly and play an important role in different application scenarios of the Internet of Things, and the demand for spatial positioning will become more and more extensive and urgent. Global Positioning System (GPS), as a relatively mature positioning technology, has been widely used in engineering survey, navigation, logistics, etc., and it is mainly used for clock synchronization and fault diagnosis in power systems. Some power stations use GPS satellite and WLAN positioning technology. Although these technologies are mature, GPS has disadvantages such as high cost, low positioning accuracy, easy to be blocked and unable...
