Abstract

The invention discloses an existence detection method and device. The existence detection method is used for dynamically detecting the existence state of larger moving subjects (e.g. people and automobiles) in a control deploying space. According to the method, the Doppler effect is utilized and the peak value and frequency of received signals are analyzed to judge existence of the larger moving subjects in the control deploying space through a microwave induction detection device, and the detection result is outputted in different signals so that a load is controlled to correspondingly respond to the detection result finally. The beneficial effects of application of the existence detection method and device are that the novel dynamic detection method and device for space existence are provided, and micro-movement of the moving subjects after entering the space can be effectively detected by the method; besides, the Doppler effect is utilized by the detection method so that no material can deliberately avoid detection; and the detection device comprises a Doppler probe and a microprocessor so that the detection device is low in cost and low in the requirement for software and hardware.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an existence detection method and device. Background technique [0002] Whether people or other moving objects enter a certain space, and whether to exit the space after entering is a problem that needs to be solved urgently in the fields of security and energy saving. At present, the existing light control, sound control and other motion sensors and infrared temperature measurement methods cannot solve the problem of ineffective detection caused by people or moving objects not moving or micro-moving after entering the detection space, and using special materials to reduce human infrared radiation. The problem. [0003] Of course, the above-mentioned dynamic detection problem can be easily solved by using the existing video surveillance or image recognition technology, but the video surveillance or image recognition technology has very high requirements on software and hardw...
