Embodiment 1

[0037] This embodiment relates to a detection device for illegal logging, such as figure 2 As shown, the illegal logging detection device is mainly composed of an audio acquisition amplifier circuit and an illegal logging detection controller. Of course, the device also includes a power supply for the audio acquisition amplifier circuit and the illegal logging detection controller (not shown in the figure). The audio acquisition and amplification circuit is mainly composed of a microphone and an audio operational amplifier circuit, which is used to obtain environmental audio data and perform amplifying processing. The microphone is commercially available. The audio operational amplifier circuit can use the LM358 typical operational amplifier circuit and other common operational amplifier circuits in the field. . The illegal logging detection controller is electrically connected to the audio acquisition and amplification circuit, and is used to collect environmental audio data t...

Embodiment 2

[0058] This embodiment provides a pirated logging detection system, see Figure 5 The system includes a monitoring terminal 1 and a number of illegal logging detection devices 2 distributed in the monitored tree planting area 3. The illegal logging detection device 2 uses the illegal logging detection device described in the first embodiment. The communication between each illegal logging detection device 2 and the monitoring terminal 1 can use the monitoring terminal to monitor the illegal logging behavior in the monitored tree planting area 3. Of course, the communication between the fraud detection device 2 and the monitoring terminal 1 in the system can be established in a wired connection manner. However, considering that for large tree planting areas, there may be situations such as too long cable routing distance, difficult cable routing with variable terrain, and complex wiring prone to failure. The illegal logging detection system of this embodiment adopts the first emb...

Abstract

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.

Description

technical field [0001] The invention relates to the technical fields of signal processing and forestry protection, in particular to a method, device and system for illegal logging detection based on audio discrimination. Background technique [0002] Illegal logging means that the perpetrator violates the Forest Law and other forest protection regulations, without obtaining a forest logging permit, and cuts down the forests and trees owned by the state, collective or others or the forests and forests of the state or collective that he contracted to manage. Behaviors: Although you have a forest harvesting license, you violate the scope specified in the forest harvesting license to harvest forests and forests that are owned by the state, collectives, or other people's own mountains or managed by others. Illegal logging not only violates the interests of forest owners, causes the loss of forestry resources, but also easily causes damage to the ecological environment. [0003] ...
