Abstracts: This design is product line counter, this system with the single chip computer and photoconductive transducer for core. When the product line have product delivering, this system can record the total amount of the current product automatically, and display manifestation data with LED, and saving this data at the same time in the hard dish of computer. In addition, product line manager can press the keyboard to control the system, so manager can manage expediently.
There are products are transmitted constantly in product line, in the middle of two products have big distance. Counter system makes use of photoconductive transducer transform products that had passed product line to the same quantity of the pulse signals, and deliver these signals to single chip computer. When the single chip computer receives a pulse signal, the counter the add 1. At the same time with the hardware and the software, system can manifestation data with save the data, or complete the other function.
