Illegal lumbering detection method, device and system based on audio frequency distinguishing

The invention provides an illegal lumbering detection method, device and system based on audio frequency distinguishing. The illegal lumbering detection method can be used for carry out distinguishing detection on illegal lumbering behavior at any time only by collecting field environment sound, has lower technical difficulty and development and use cost, and has higher detection and execution efficiency. Corresponding, the illegal lumbering detection device utilizing the method has the characteristics of low development cost, short period and high efficiency, and is suitable for industrial development and production. At the same time, an illegal lumbering detection system is constructed by virtue of the illegal lumbering detection device with a wireless communication function, thus remote monitoring to illegal lumbering detection is achieved, the position in which the illegal lumbering behavior is judged to happen is determined, and the illegal lumbering behavior is prevented by specifically adopting coping measures. The illegal lumbering detection method, device and system based on audio frequency distinguishing can solve the problems of difficulty in detection of illegal lumbering behavior and high cost in the prior art, and have broad application prospects.
