This paper aims to solve the problems of the existence of secondary fermentation medium low yield, the poor product identity, the low level of automation, the high energy consumption and many other urgent problems, as well as the complexity of the secondary fermentation medium temperature control inside the tunnel by proposing a computer control system based on PLC, with the computer data acquisition and the real-time control of fermentation process. Fuzzy PID control algorithm is adopted in the system, the fuzzy controller and PID adjustor are realized by PLC, which not only has the agile, reliable peculiarity and the ability of antijamming of a PLC control system, but also improves considerably the intelligence level and the control precision of the control system. The practice results show that the system can effectively control the secondary fermentation medium temperature inside the tunnel, greatly improve the level of automation, and the quality of the products, reduce the labor intensity and the human losses and costs, reduce the energy consumption, with good economic and social benefits.
