Indoor positioning and monitoring system based on UWB

Abstract

The invention provides an indoor positioning and monitoring system based on UWB, comprises a remote monitoring and command platform, a movable positioning device arranged outside the fire accident scene, a UWB node arranged on the fire rescue personnel entering the fire accident scene, a physiological condition monitoring module, an environment monitoring module, a data transmission module and analarm module, wherein the remote monitoring and command platform comprises a remote monitoring and command platform, a movable positioning device arranged outside the fire accident scene, a UWB node arranged on the fire rescue personnel entering the fire accident scene, a physiological condition monitoring module, an environment monitoring module, a data transmission module and an alarm module. The invention adopts the movable UWB anchor node, and can quickly establish a spatial positioning system at the scene of a fire accident, so as to carry out real-time positioning on the fire rescue personnel entering the scene of the accident, and has high flexibility and adaptability. Through the data sensed by the sensors, the physiological and environmental conditions of the fire rescue personnelcan be obtained in real time, and the personal safety of the fire rescue personnel can be effectively ensured. Through the remote monitoring and command platform can be seen all fire rescue personnelin the scene of fire accidents in the specific location and physiological and environmental conditions can be effective rescue deployment command and provide the best rescue escape route.

Description

technical field [0001] The present invention relates to the technical field of electronic information and communication, and in particular to a UWB-based indoor positioning and monitoring system that can realize rapid location of a fire accident scene and real-time monitoring of vital signs and environmental conditions of fire rescue personnel entering the accident scene. Background technique [0002] In recent years, casualties of fire rescue personnel have occurred from time to time during the fire rescue process of the fire brigade. Therefore, when a natural disaster (such as a fire) occurs, the rescue work of fire rescue personnel in distress has also become an important part of the rescue process. As we all know, the environment of the fire scene is complex, accompanied by factors such as dense smoke, high temperature, water vapor, flammable and explosive materials, toxic gas and dust, and low oxygen content in the air, which always threaten the life safety of fire resc...

Problems solved by technology

Ultrasonic and radar are a technology that uses the reflected wave of the transmitted signal to determine the position of the target. The main disadvantages are the limited propagation distance and the poor ability to penetrate obstacles.

Infrared positioning and RFID positioning generally use the sensor network to monitor the signal strength of the target to achieve the positioning purpose, which requires placing sensors indoors in advance and establishing a sensor network. For those without a preset sensor network Buildings or buildings that do not meet the placement conditions, the positioning cannot be implemented
