Abstract: In order to solve the problems of low efficiency and high labor intensity in the packaging process of black gadfly larvae, this design takes Mitsubishi FX3U PLC as the control core, and builds a real-time monitoring system of black gadfly larvae packaging production line based on MCGS Pro configuration software. By utilizing multi-sensor modules to collect operational status, real-time tracking and monitoring of feeding, weighing, bagging, bagging, and packaging actions during the packaging process can be achieved, thereby achieving remote monitoring of the production line. The simulation operation results indicate that: the system can realize man-machine interaction, has good real-time performance and high reliability, and will have broad demand space and application prospect in factory packaging production line operation.
