Small and micro animal detector and method for hiding in cabin and biological radar sensor

Abstract

The invention belongs to the technical field of aviation safety detection and discloses a microfauna detector and method used for hiding in a cabin and a biological radar sensor. The microfauna detector used for hiding in the cabin is used for collecting the vital sign information of microfauna. The number of the JC122 biological radar sensors used for detecting the small and micro animals hiddenin the cabin is ten. The microfauna detector comprises a JC122 biological radar sensor, a signal preprocessing and multipath information synthesis module, a signal equalization processing module, a microfauna vital sign information extraction module, an information enhancement module, a wireless data transmission module and PDA software intelligent discrimination equipment, and a lithium ion battery is used for supplying power. A plurality of devices are synchronously detected at one time, so that the working efficiency is improved; meanwhile, the area where the small and micro animals are located in the cabin can be indicated, 2*10 m long-distance vital sign information level omnibearing detection is achieved, and the detection and use requirements of various types of airplanes are met.

Description

technical field [0001] The invention belongs to the technical field of aviation safety detection, and in particular relates to a small and micro animal detector, method and bio-radar sensor used for hiding in a cabin. Background technique [0002] At present, the small and micro animals hidden in the cabin are related to flight safety, invasion of alien species, and epidemic prevention, etc., and are a problem that plagues customs and aviation departments. This problem puts customs and shipping departments under increasing pressure as the process of internationalization accelerates. [0003] Due to the strong timing of the flight of aviation aircraft, it is impossible to ground every aircraft and kill them all on a regular basis. How to kill aircraft with rodent infestation in a targeted manner and avoid unnecessary losses caused by aimless killing. First, it is necessary to identify whether there are "presence" or "no" small animals in the cabin; off. [0004] At present...

AI Technical Summary

Problems solved by technology

[0014] First, the electronic noise of the circuit is at the microvolt level, and the vital sign information at the microvolt level is lost in the electronic noise;

[0015] Second, highly sensitive detection instruments are extremely susceptible to interference from the external environment
