Example Embodiment

[0017] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0018] As shown in Figure 1, the UWB autonomous positioning system for fire rescue includes a shoe-mounted autonomous positioning sensor, a UWB positioning module that communicates with the shoe-mounted autonomous positioning sensor through wireless communication, and a UWB positioning network base station;

[0019] The shoe-mounted autonomous positioning sensor includes an Arduino controller, a sensor connected to the Arduino controller, and a wireless transmitting module connected to the sensor;

[0020] The sensors include accelerometer sensors, gyroscope sensors, magnetic sensors, air pressure sensors and temperature sensors. In the autonomous navigation state, the shoe-mounted autonomous positioning sensor relies on the Arduino controller to control the accelerometer / gyro / magnetometer and air pressure. The data sensed by the sensor chip such as the me...

Abstract

The invention relates to the technical field of indoor autonomous positioning, and especially relates to a UWB autonomous positioning system for rescue in a fire scene. The UWB autonomous positioning system comprises a shoe-borne autonomous positioning sensor, a UWB positioning module connected with the shoe-borne autonomous positioning sensor through wireless communication, and a UWB positioning network base station. Signal transmission is carried out between the shoe-borne autonomous positioning sensor and the UWB positioning module through a micro-strip antenna. Signal transmission is carried out between the UWB positioning network base station and the UWB positioning module through a UWB radar transceiver module. The UWB autonomous positioning system further comprises a background command platform including a PC or server, and the background command platform communicates with the UWB positioning network base station through a WIFI antenna or LAN interface. The requirement for real-time and high-accuracy fire scene rescue personnel autonomous positioning is satisfied, and guarantee is provided for the combat command of commanders outside the fire scene and the safety of fire fighters inside the fire scene.

Description

technical field [0001] The invention relates to the technical field of indoor autonomous positioning, in particular to a UWB autonomous positioning system for fire rescue. Background technique [0002] At present, the application of positioning technology has widely penetrated into various fields of national economy and social development, and outdoor positioning technology has been very mature with the help of global navigation satellite systems (GNSS) such as GPS. However, satellite signals cannot penetrate buildings, and the indoor environment is complex, with serious multipath and non-line-of-sight interference. It is difficult to achieve positioning indoors, and indoors are the most closely related to human life and production. Application requirements. For example, in fire fighting, the nature of the firefighters' work is highly dangerous. They may enter some complex high-rise buildings, and the firefighters' own safety becomes a problem. The multipath effect is seri...
