Design of the temperature controlled system of the nonwovens line with method of melting spray by microcomputer

The hardware structure and control software of temperature control system on the nonwovens line by MCS-51 single-chip computer were introduced. To improve the precision of the control, the control method of PID added expert control was used. The temperature of seven ways could be controlled at the same time. This system was the better control system with quicker response, lower excess of the requlation and higher precision of steady state. The unique interface between the keyboard and monitor was formed,so that the reset and test could be done anytime without stopping working of the system.
