Omnibearing wireless personnel positioning and tracking system

Abstract

The invention, which relates to the positioning and tracking system field, provides an omnibearing wireless personnel positioning and tracking system. According to the invention, personnel positioning is carried out based on a mode of integration of global positioning system (GPS), location based service (LBS), and wireless radio frequency chip single strength value positioning, thereby meeting the requirement of indoor-outdoor omnibearing positioning and tracking for the personnel. Moreover, the positioning process is in a seamless connection mode, thereby guaranteeing that personnel position information can be obtained rapidly when in need. The system has advantages of low equipment cost, simple construction, flexible system configuration, and convenient usage. Meanwhile, the system can be integrated with other information system services and the application can be expanded.

Description

technical field [0001] The invention relates to the field of positioning and tracking systems, in particular to a positioning and tracking system for omnidirectional wireless personnel. Background technique [0002] In some dangerous working environments, through real-time positioning and tracking of personnel, targeted and targeted measures can be taken in the event of accidents; in hospitals, schools, nursing homes and other service institutions, patients and students Real-time positioning and tracking of service objects such as , the elderly, etc., can provide them with better services and effectively prevent accidents from happening. [0003] At present, there are several methods for wireless personnel location tracking: [0004] (1) The wireless positioning based on GPS (Global Positioning System) is a satellite navigation and positioning system developed by the United States. With this system, users can realize all-weather, continuous, real-time three-dimensional navi...

AI Technical Summary

Problems solved by technology

[0008] (1) Although the GPS positioning and tracking method has high positioning accuracy, it can only be used for outdoor positioning, and indoor positioning and tracking cannot be achieved due to signal occlusion.

[0009] (2) Although the LBS positioning and tracking method can achieve all-round positioning, this positioning method is limited by the deployment density of mobile base stations, and the positioning accuracy is poor

[0010] (3) The positioning accuracy of the positioning tracking method based on the signal strength of the wireless radio frequency chip is between the above two, but this method requires both the transmitting node and the receiving node to participate in the positioning. It is stipulated that it is below 10dBm, and the wireless communication distance can only be within a few hundred meters, so this positioning method can only be applied to short-distance positioning within a certain area

[0011] However, combining the above-mentioned multiple positioning methods to realize a comprehensive wireless personnel positioning system anytime and anywhere has not yet been reported.
