Abstract

The invention discloses a detection method and device for personnel positioning in a smog scene. The device includes a microprocessor, a smoke sensor, a millimeter-wave radar, an NB-IoT module, and a power supply module; the method is: a millimeter-wave radar The echo signal is mixed with the transmit signal to obtain a beat intermediate frequency signal; the ADC samples the beat intermediate frequency signal to obtain an echo sampling sequence; and through sequential distance processing, static clutter filtering, and CAPON beamforming, CFAR target detection, speed estimation, distance azimuth map and detection point cloud collection; group tracking on point cloud collection, acquisition of target position and trajectory, micro-motion recognition of the target, and output of detection results. The invention integrates the millimeter-wave radar and the smoke sensor to improve the popularity of the millimeter-wave radar; at the same time, the millimeter-wave radar has high precision and anti-interference characteristics to quickly locate the position of the trapped person in the smoke scene and save rescue time.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a detection method and device for personnel positioning in a smoke scene. Background technique [0002] The smoke scene is very complex, with dense smoke and high temperature, most sensors will fail in this scene. Smoke alarm is a fire detection alarm that perceives smoke. When a fire occurs, the probe of the smoke alarm can detect a large amount of smoke generated during the fire, thereby sending out an alarm signal. However, traditional smoke sensors can only detect smoke, but cannot identify and locate people trapped in the smoke. How to quickly locate and track trapped people in the smoke scene after a fire has become the focus of attention. [0003] Traditional positioning techniques include: [0004] 1. Laser radar technology [0005] The laser radar emits a laser beam, and obtains the position and speed of the target by comparing the reflected signal with the ...
