Problems solved by technology

Common GPS navigation, Beidou navigation, etc. are all satellite navigation. Beidou / GNSS satellite positioning navigation is characterized by supporting BDS / GPS / GLONASS multi-system joint positioning, faster positioning response speed and stronger anti-interference ability, but the positioning accuracy is poor ( 5-10 meters), cannot achieve high-precision positioning (high-precision positioning requirements: 10cm-50cm)
[0004] In the existing technology, both establishing UWB positioning technology alone and using satellite positioning technology alone can solve the personnel positioning needs in the factory environment of chemical enterprises, but there are some defects: for example, independent UWB positioning relies on the layout of multiple base stations, so it requires high cost Base station layout costs, and some chemical enterprise factories have explosion-proof requirements, and UWB base stations also need to meet explosion-proof requirements, which increases the cost and difficulty of a large number of follow-up maintenance work
In addition, the use of satellite positioning technology alone cannot meet the requirements of high-precision positioning of personnel in chemical enterprises.

Abstract

The invention discloses a safety positioning system and method for personnel in an region in the technical field of personnel safety positioning. The system comprises a fusion positioning system which is used for carrying out the precise positioning of personnel in a chemical plant region; and/or the access control system is used for carrying out identity recognition on the personnel entering the access control entrance and exit of the chemical plant region; and/or the safety management system is used for carrying out comparison processing according to information transmitted by the fusion positioning system and the access control system and carrying out safety supervision on personnel in a chemical plant region, and the fusion positioning system is in butt joint with the access control system through fusion of a satellite positioning technology and a UWB positioning technology. The optimal personnel safety positioning system in the chemical plant region is realized.

Description

technical field [0001] The invention relates to personnel safety positioning technology in a specific area, and more particularly relates to a personnel safety positioning system and a positioning method in an area based on satellite positioning and UWB positioning fusion technology. Background technique [0002] In a certain area, the precise positioning of personnel, and the positioning system is required to be simple and low-cost has always been a disturbing problem. Especially in the production process of chemical enterprises, the positioning of staff has become a major focus and difficulty in personnel safety management. There are more and more demands for personnel positioning in the whole enterprise factory area and in multiple spaces. With the continuous improvement of the demand for fewer people and the continuous improvement of safety requirements, the demand for real-time positioning of personnel on site, query of inspection records, and precise positioning of pe...
