Non-contact insect charge-measuring system

Abstract

The invention relates to a non-contact insect charge-measuring system which comprises an electric field sensor unit, a control and signal-processing unit, a data storage display and power supply unit and can measure an insect charge signal in a non-contact electric field induction mode. The system can measure the electric field signal of an insect in a natural motion state in normal motion environment without changing the charge distribution of the insect, can truly reflect the charge characteristic of the insect in the natural condition, acquire the low-frequency electromagnetic characteristic data of the insect by analyzing collected data, extract the charge characteristic of the insect, and accurately and effectively trap the insect. The non-contact insect charge-measuring system has long service life and wide application prospects in insect basic theoretical research and the field of pest prevention and control.

Problems solved by technology

[0002] At present, the research on the charging characteristics of insects at home and abroad is to measure the charging characteristics of insects by placing the insects to be tested in the Faraday bucket, making the insects directly contact with the Faraday bucket, and measuring the magnitude of the current generated by the insect charge flowing to the earth through the Faraday bucket. , this measurement method changes the insect's activity environment, changes the charge distribution on the insect, and cannot truly reflect the charging characteristics of the insect in the natural environment

At present, there is no device for measuring insect charge by non-contact measuring the electric field generated by insect charge, and the sensor for measuring quasi-electrostatic field currently used in other fields is a field mill rotary type, which has low measurement accuracy and large error. The grounding brush is used, the service life is short, and the measurement noise is relatively large, so it is not suitable for measuring insect charges.
