Overview
The pest detection system for stored grain is affected by various factors, and its insect density is constantly changing, making it difficult to predict using models. However, using an acoustic automatic monitoring system can greatly simplify the problem. The principle is to use modern digital filtering technology to separate the frequency range of the sound emitted by insects from other sounds
Product Details
The pest detection system for stored grain is affected by various factors, and its insect density is constantly changing, making it difficult to predict using models. However, using an acoustic automatic monitoring system can greatly simplify the problem. The principle is to use modern digital filtering technology to separate the frequency range of the sound emitted by insects from other sounds. The percentage of sound intervals produced by insects is related to the number of insects, and the number of intervals is related to the number of insect species. The sensor used is a sound sensitive component. The experimental results show that this method can effectively identify hidden pests in grain, thus achieving automatic identification and detection of pests in stored grain and various grain procurement purposes.
Main performance indicators: 1 Tested insect species: 3-10 species; 2. Measurement time: 30 seconds; 3. Environmental temperature: -10-45 ℃; 4. Measurement points: 1-256; 5. Frequency range: 20Hz-16kHz.
