Embodiment

[0031] Such as figure 1 As shown, a mobile wireless positioning method of the present invention includes:

[0032] 1) Place three or more wireless positioning piles 2 (generally 4, such as figure 1 shown), and form a wireless communication network with the computer or handheld device 1 in the command center; that is, to enable normal communication between the wireless positioning post 2 and the computer or handheld device 1 in the command center;

[0033] 2) The wireless positioning post 2 obtains its own geographical location information through its GPS module. After the wireless positioning post 2 adds the geographical location information to the wireless positioning post 2's marking information, it sends it to the computer in the command center through its first wireless module. Or on the handheld device 1, the computer of the command center or the positioning tracking software of the handheld device 1 determine the scope of the delimited area through the position informat...

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 invention relates to the field of wireless positioning, in particular to a mobile wireless positioning method and system. Background technique [0002] When a disaster occurs, the emergency scene 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 the rescuers. The position of emergency personnel at a dangerous scene is very important to emergency command personnel. By obtaining the location information of emergency personnel, it can help on-site commanders to command better, reduce the probability of casualties of emergency personnel, and at the same time command personnel in dangerous areas 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 underground personnel; at least two positioning auxiliary stations for positioning the positi...
