Management and control system for fireman locating and tracking

Abstract

The invention belongs to the wireless communication field, in particular to a management and control system for fireman locating and tracking. The management and control system for the fireman locating and tracking comprises a wireless terminal device, a wireless access point, a wireless communication network, a locating server and a management and control system platform, the wireless terminal device is connected with the locating server through the wireless access point of the wireless communication network, and the locating server is connected with the management and control system platform; the wireless access point is used for receiving signals sent by the wireless terminal device and sending the received signals to the locating server to process through the wireless communication network, the position of the wireless terminal device is determined through the locating server, and the device information is sent to the management and control system platform to realize the position management and control for the wireless terminal device.

Description

technical field [0001] The invention belongs to the field of wireless communication, and specifically provides a positioning tracking control system for firefighters. Background technique [0002] When dealing with uncertainties, especially in the indoor space environment of unforeseen structures, the traditional firefighter target positioning and tracking methods either use low-quality perception correction methods, which lead to the loss of perceptual information; or sacrifice the accuracy of the tracking method. Flexibility and practicality; or consume more network energy to reduce the impact of uncertainty. These include pseudolite indoor positioning and Google Maps to quickly form the longitude and latitude values ​​of the 3D geographic coordinate model extension. [0003] These traditional firefighter target positioning and tracking methods cannot truly achieve target positioning and tracking in the complex and changeable indoor space environment of structures with l...

Problems solved by technology

[0003]These traditional firefighter target positioning and tracking methods cannot really achieve target positioning and tracking in the complex and changeable indoor space environment of structures with low visibility and unpredictability

The main problems are: 1. Indoor is the blind area of ​​satellite positioning. Recently, many indoor satellite positioning adopts penetration technology, which is theoretically feasible, but in reality, it is affected by the large drift in the time domain and the difference, so it cannot be positioned correctly for a long time. At the same time, satellite positioning is only It can indicate the position on a plane, and cannot distinguish between upstairs, downstairs, basement, etc.

If it is used as a firefighter's personal equipment, although there is a certain degree of visibility in the usual rehearsal, the time and place of fire accidents and disasters may be uncertain, and the equipment at the preset positioning reference station may be damaged in disaster accidents, etc., its application extremely low value

Many other wireless network target positioning and tracking methods, although some use Google Maps to quickly form a three-dimensional geographic coordinate model, extended longitude and latitude values, and track the three-dimensional movement trajectory of personnel on the spot, etc., but the wireless network target positioning technology has large errors and has It has great limitations, and at the same time, it cannot correctly judge the target positioning height and horizontal line, and cannot distinguish the upstairs, downstairs, basement and other locations, so it cannot really solve the personal positioning and tracking of firefighters in the indoor space environment of unforeseen structures.
