Automated production line has been used more and more widely in our daily life. The function of automatic production line has great influence on production efficiency. Therefore, the function of automatic production line must be improved, and the operation of automatic production line can be ensured. The traditional automatic production line system adopts the relay logic control circuit, which is easy to malfunction, inconvenient to maintain, short service life and large space occupation, and is being phased out gradually. This design uses SIEMENS S7-200 single chip microcomputer as the control unit, and uses software to realize the automatic control of the automobile carpet heating line. Carpet heating line has complete temperature test system, fault alarm system, automatic heating system and safety loop system. The reliability of automobile carpet heating system is greatly improved. The control system of automobile carpet heating system is simple, the outer circuit is simplified, and the control function can be easily changed. The utility model improves the safety of the operation of the automobile carpet heating system and is easy to overhaul. Therefore, it is with excellent temperature debugging function, automatic heating function, high efficiency and good energy-saving effect and wide application range, thereby significantly improve the heating quality and performance of the car carpet, control c
