Through in chemical, petrochemical and papermaking of hundreds of enterprise (device), promote enterprise's technical renovation, improve the production process control level and product quality, to create the obvious economic benefit. According to the design of the industrial control and intelligent control technology and electronic technology, based on single-chip microcomputer control technology, the design of the experiment of industrial control circuit is simple. With the system hardware platform for reliable performance, stable work, powerful design principle, the overall performance of low power consumption by MPS430 microcontroller as the core. By the sensor, drive, relays and industrial control equipment as the main body. Then, VB programming complete data acquisition, VB program design, complete control own serial chip to send command. Design of serial C programming language application and single-chip microcomputer control procedures, realize the writing of stepping motor chip, dc motor starting, stopping, deceleration, status, circuit breaker relays and continuity of control. Finally, simulation of industrial control way and demonstration debugging. Key Words：MSP430 F149; L297 N;L298 N;Place of honor machine;
