The industry control computer is as the core of computer distributing scale, use special distributing meter to receive and display signal lamp detected by high accuracy sensor. The datas transmit between the serial port EIA-RS232 of industrial control computer and the serial port RS232 of distributing meter. The industrial control computer can realize fast charging, slow charging, stop charging and turn to another material distributing through weight signal of sensor, realizing fully automatic distributing process. Could be widely used in the control of distributing and mixing process for grain, feed, cement, chemistry, building and food industries.
