UWB-based system and method for positioning external personnel of key area

Abstract

The invention discloses a UWB-based system for positioning the external personnel of a key area. The system comprises visitor registration equipment, a positioning label, a plurality of positioning cells, a positioning resolving module and an information management module. The visitor registration equipment is used for carrying out identity verification on an external person and inputting the information of the external person. The positioning label is worn on the external person, and is used for generating and sending a UWB pulse signal with self equipment information. The positioning cells are arranged in the key area, and comprise four UWB positioning base stations. The four UWB positioning base stations are used for receiving UWB pulse signals sent by the positioning label, and sendingthe time and base station position information of the received UWB pulse signals of the positioning label to the positioning resolving module. The positioning resolving module is used for resolving data sent by the four UWB positioning base stations of one positioning cell to obtain positioning coordinates of the positioning label. The information management module is used for giving an alarm according to the positioning coordinates provided by the positioning resolving module.

Description

technical field [0001] The present invention relates to the field of UWB positioning, in particular to a UWB-based system and method for positioning foreign personnel in key areas. Background technique [0002] With the development of wireless communication technology, the world in the 21st century will soon enter the era of wireless interconnection from the network era. Emerging wireless network technologies, such as WiFi, WiMax, ZigBee, Ad hoc, BlueTooth and UltraWideBand (UWB, ultra-wideband), have been widely used in all aspects of public life such as offices, homes, factories, parks, etc. Wireless network-based positioning technology The application has more broad prospects for development. [0003] In addition to the application of global positioning system (GPS) in navigation and outdoor environment positioning, people do not know much about applications such as indoor positioning, outdoor precise positioning in parks, and short-distance positioning. The future tren...

Problems solved by technology

[0013] According to the research and on-site investigation and analysis of various parks, it is found that many parks currently have backward management informatization methods, and information sharing among business departments cannot be realized, forming information islands

Lacking the support of the business management system, the complexity of the management process and the low efficiency make the management system unable to be implemented, resulting in many management loopholes

For example: whether the foreign visitors have left the park cannot be checked, whether the foreign visitors are in the correct access area cannot be automatically judged, foreign visitors may break into unauthorized buildings or indoor key sensitive areas, etc.
