Capacitance counting module for insect pest detection and insect pest detection device and method

Abstract

The invention discloses a capacitance counting module for insect pest detection, an insect pest detection device and an insect pest detection method. The module comprises a base, a porous fairing, a capacitance plate, a shell and a processing unit, wherein the base is provided with an inner interlayer and an outer interlayer which are concentric, the outer interlayer is located outside the inner interlayer, and the area between the inner interlayer and the outer interlayer is communicated with the outside. The porous fairing is arranged in a manner of gradually shrinking from bottom to top andis arranged on the inner interlayer; the inner capacitor plate is adjacent to the inner interlayer, and the outer capacitor plate is adjacent to the outer interlayer and faces the inner capacitor plate to form a capacitor plate pair; partition plates are arranged on the base to equally divide the area between the inner interlayer and the outer interlayer and separate the adjacent capacitor platepairs, and every two partition plates and the capacitor plate pair between the two partition plates jointly define a capacitor detection area. The processing unit is connected with each capacitor plate pair and is used for detecting the capacitance value of each capacitor plate pair in real time, judging whether pests exist in each detection area or not and obtaining a pest counting result. According to the invention, pest detection and counting can be reliably and accurately realized.

Description

technical field [0001] The invention relates to the technical field of pest detection in digital agriculture, in particular to a capacitance counting module, a pest detection device and a method for pest detection. Background technique [0002] Agricultural informatization is to infiltrate modern information technology into agricultural production, consumption and other links. Digitization, automation and intelligence are the future development trends of agriculture. In agricultural production, insect pests are an important factor affecting crops, so it is necessary to take insect pests as the key monitoring object and count the situation of pastoral insect pests. [0003] The traditional method of counting pests mainly uses manpower. Farmers go to the field to count pests. The cost is high, the workload is heavy, and it takes a long time. It is limited by manpower and weather. This method is only suitable for small-scale agriculture. Pest monitoring in large and widely dis...

Problems solved by technology

[0003] The traditional counting of insect pests mainly uses manpower. Farmers go to the field to count insect pests, which is costly, heavy workload, and time-consuming. Limited by manpower and weather, this method is only suitable for small-scale agriculture. Pest monitoring in large and widely distributed areas, applying Internet of Things technology to pest monitoring, sustainable and efficient pest monitoring

Among the commonly used pest counting methods, voltage and current pulses are applied to pest counting, but this method has disadvantages such as high energy consumption, great environmental impact, and fire risk.

There is also the use of insect pest image counting, and the counting is realized through pest image recognition, but there are disadvantages such as complex mechanism, camera surface is easily dirty, photographing is easily affected by light conditions, resulting in false detection, and frequent maintenance is required.

Visible, these methods all have weak point, therefore be necessary to work out new pest counting technique
