Abstract

The invention provides a rescuer indoor cooperated positioning device and a method. A system comprises at least three inertial navigation positioning devices, a plurality of single chip microcomputers, a plurality of ZigBee wireless sensor network nodes, a plurality of GPRS modules, and a remote server. The inertial navigation positioning devices are separately disposed on at least three rescuers. All the rescuers are provided with one of the single chip microcomputers, one of the ZigBee wireless sensor network nodes and one of the GPRS modules. The inertial navigation positioning devices are carried by some of the rescuers, thus achieving indoor positioning. A real-time positioning network is formed through a ZigBee wireless sensor network, and position data is provided for other rescuers not carrying the inertial navigation positioning devices in a rescuing site. When a rescuer can verify the position of himself or herself, the position information can be corrected and the precision of a dynamic positioning network can be corrected. A headquarter can know the positions and distribution of the rescuers on the site in real time, and the rescuers can known the position information of themselves and their teammates, thus increasing the disaster rescuing efficiency so as to guarantee human safety.

Description

technical field [0001] The invention relates to the fields of indoor positioning, wireless sensor networks and disaster rescue, and in particular to an indoor collaborative positioning device and method for rescuers. Background technique [0002] In disaster rescue activities, the rescuers who charge on the front line are often in danger, and their life safety is difficult to be effectively guaranteed. Rescuers cannot understand information such as the location of themselves and their team members indoors, and cannot provide mutual support in a timely and effective manner when a critical situation occurs, which can easily lead to casualties. At the same time, the commanders and on-site personnel cannot grasp the implementation status of the rescuers, and cannot immediately make correct judgments and reasonable commands on the situation faced by the rescuers, which seriously affects the command efficiency. Therefore, it is very necessary to locate the rescuers indoors and le...
