DESIGN OF PRODUCT COUNTING SYSTEM BASED ON STC89C52

Product measurement is an important link in production. This project is mainly applied to production line output statistics, output arrangement and visual management of production progress in the manufacturing industry.The system takes STC89C52 as the main controller and the Opposite infrared sensor as the detection unit to automatically detect the actual quantity of products on the production line and display data such as time, temperature, actual output, and planned output. The system has strong anti-interference ability, selectable counting modes, and supports infrared remote control and RS485 communication methods, and can provide dynamic data to the computer management system. Experimental results show that the system runs stably and meets the design requirements, and can provide an important basis for process control in the manufacturing field.
