Person safety composite positioning system and positioning method

Abstract

The invention relates to a person safety composite positioning system and a positioning method. The positioning system comprises a physical sign sensing device, a carrying device and a commanding device, wherein the physical sign sensing device is provided with a physical sign sensor and a physical sign sensing-end Bluetooth circuit; the carrying device is provided with a carrying-end Bluetooth circuit, a three-axis gyroscope, a three-axis acceleration sensor, an air pressure sensor, a temperature and humidity sensor, a satellite circuit, a sound and light alarm, a voice communication circuit, a camera, a carrying-end data transmission circuit and a core processing circuit matched with the physical sign sensing-end Bluetooth circuit; and the commanding device is provided with a commanding-end data transmission circuit matched with the carrying-end data transmission circuit and a commanding platform for processing the transmitted data to form person positioning, person state monitoring and person commanding signals. The positioning method adopts the positioning system for positioning.

Description

technical field [0001] The invention relates to the technical field of positioning systems, in particular to a personnel safety composite positioning system and a positioning method. Background technique [0002] With the needs of information technology and the safety of personnel themselves, people's demand for their own positioning is becoming stronger and stronger, especially when they act collectively, the acquisition of each person's location and status information is the prerequisite for effective command, especially in disaster relief activities Among them, the rescuers rushing to the front line are often in danger, and the positioning needs of rescuers are even more urgent. [0003] The current command system is composed of multiple explosion-proof handheld radios. In the actual use process, the location and status of rescuers can be determined through calls. However, this command system cannot solve the problems of personnel positioning, status monitoring and comman...

AI Technical Summary

Problems solved by technology

[0003] The current command system is composed of multiple explosion-proof handheld radios. In the actual use process, the location and status of rescuers can be determined through calls. However, this command system cannot solve the problems of personnel positioning, status monitoring and command when personnel act collectively.

During the rescue process, rescuers cannot know the location of themselves and their team members, and cannot provide timely and effective support to each other in a critical situation, which can easily lead to casualties

At the same time, commanders and on-site personnel cannot grasp the real-time location and situation of rescuers, and cannot immediately make correct judgments and reasonable commands on the situation faced by rescuers, which seriously affects the command efficiency.
