Novel fireground fire protection single soldier positioning system

Abstract

The invention discloses a novel fireground fire protection single soldier positioning system which comprises a handheld terminal unit, a first monitoring unit, a second monitoring unit, a third monitoring unit and a monitoring terminal unit; the handheld terminal unit regularly sends terminal positioning information to the first monitoring unit, the second monitoring unit and the third monitoring unit respectively, calculation is conducted on the received terminal positioning information by the first monitoring unit, the second monitoring unit and the third monitoring unit, the distance between the first monitoring unit and the handheld terminal unit, the distance between the second monitoring unit and the handheld terminal unit and the distance between the third monitoring unit and the handheld terminal unit are obtained, the first monitoring unit, the second monitoring unit and the third monitoring unit send the respective position information and the respective calculation results to the monitoring terminal unit, and the position of the handheld terminal unit is finally precisely calculated out by the monitoring terminal unit. The system is easy to obtain and reliable in transmission; an active positioning mode is adopted, so that arranging base station equipment in the fireground in advance is not needed, and flexible deployment is achieved; the system is suitable for wirelessly positioning fire protection soldiers under emergency.

Description

technical field [0001] The invention relates to an individual soldier positioning system, in particular to a novel fire-fighting individual soldier positioning system, which is suitable for providing fire fighters with individual soldier positioning services in the fire scene in an emergency situation. Background technique [0002] Urban firefighters often encounter some sudden dangerous situations during fire fighting and rescue operations, so how to accurately judge the specific location of firefighters in the fire scene is very important. Most of the existing positioning algorithms assume that the firefighters are stationary or the GPS points arranged in advance are positioned. Since the places where urban fires occur are mostly located indoors or are blocked by other buildings, satellite positioning methods such as GPS and Beidou cannot However, positioning methods like RFID or ZigBee need to deploy mobile forwarding equipment or positioning base stations in the fire sce...

Problems solved by technology

Most of the existing positioning algorithms assume that the firefighters are stationary or the GPS points arranged in advance are positioned. Since the places where urban fires occur are mostly located indoors or are blocked by other buildings, satellite positioning methods such as GPS and Beidou cannot However, positioning methods like RFID or ZigBee need to deploy mobile transponders or positioning base stations in the fire scene, and require special hardware support, so the feasibility is limited.
