A mobile wireless positioning method and system

Abstract

The invention discloses a mobile wireless positioning method and a mobile wireless positioning system. The method comprises the following steps that rescue personnel fixedly arrange three or more than three wireless positioning piles around an accident area in case of disaster, and switch on a power supply, and a computer or handheld equipment of a command center acquires the position of each wireless positioning pile and distances between every two positioning piles in a wireless communication way, and divides the range of the accident area; when personnel wearing position trackers enter the divided area, each wireless positioning pile can receive microwave signals transmitted by the position trackers, calculate distances between the position trackers and the wireless positioning pile, and transmit distance information to the computer or the handheld equipment of the command center; and the computer or the handheld equipment of the command center calculates the relative positions and the movement trajectories of the position trackers in the divided area according to the information. The wireless positioning piles can be used for simultaneously tracking a plurality of position trackers with different serial numbers, and transmitting the distance information to the command center in a classification way, so that the scheduling accuracy of the command center can be ensured.

Description

technical field [0001] The present invention relates to the field of wireless positioning, in particular to a movable wireless positioning method and system. Background technique [0002] When a disaster occurs, the scene of danger is usually in an unknown and uncertain area, and it is impossible to set a fixed positioning system in advance to locate the position of rescue personnel. The location of the rescue personnel at the dangerous scene is very important to the rescue commander. By obtaining the location information of the rescue personnel, it can help the on-site commander to better command, reduce the probability of casualties of the rescue personnel, and command the personnel in the dangerous area at the same time. escape. [0003] Chinese utility model application 201220616901.X discloses a positioning device for underground personnel in a mine, which includes: a positioning card placed on the body of the underground personnel; at least two positioning auxiliary s...
