A QUANTITATIVE STORED-PRODUCT INSECT MONITORING SYSTEM USING SENSOR OUTPUT ANALOG PROCESSING (SOAP)

摘要

A system is described for automated monitoring of pest insects in stored products. It provides quantitative data indicative of the species of detected insects and is self-calibrating to maintain reliable operation across adverse external conditions, including environmental, biological, and aging. The system employs grain probes with infrared beam optoelectronic sensor units, each having a dedicated electronic circuit with a microcontroller programmed to collect, analyze, store, and transmit data from a signal pulse generated when an insect falls through its infrared beam. These data, transmitted back to a central computer in real-time, can be used to make infestation control decisions in an IPM program without the need for dangerous and labor-intensive scheduled bin entries
