Based on Hilbert transformation, a pest counting system and remote publishing system were designed and established. The system was composed of pest–killing lamp, acquisition card, voltage transformer, PLC, and router, etc. Under operation, the voltage from pest–killing lamp was reduced by voltage transformer, and then collected by acquisition card, which connected with PC by USB. LabVIEW was used to complete the Hilbert process to obtained the instantaneous value. When the instantaneous was less than the set value, modbus instruction was sent to PLC serial port, and PLC will count at receiving corresponding instruction. PLC and MySCADA were introduced to attain remote publishing on mobile phone and computer. Disturbance information of 714 pests were analyzed, and totally 4 terms of 7 disturbance information were listed in the paper. The result showed that the system could precisely identify 7 disturbance area, and display by mobile phone and remote computer.
