Th-2005b biochemical process control system developed by Tianhui company is composed of industrial control computer and I / O module. It adopts 10.4-12 inch high standard liquid crystal touch screen as man-machine interface. It has rich display contents, simple and convenient operation. One controller can control multiple fermentation tanks at the same time, and can not be equipped with upper computer.
The TH-2005C type biochemical process control system developed by Tian Hui company has independent control module. The parameters of temperature, pH, dissolved oxygen, rotational speed, air flow and tank pressure are controlled by fuzzy PID intelligent controller with self setting function. The control of foam and feeding is controlled by time sequence. Each independent parameter can be connected to the upper computer through process bus.
Th-plc fermentation control system, the control components are mainly composed of PLC, CPU, I / O board and operating computer (or human-computer interface), with the characteristics of centralized management and decentralized control. The control calculation and fermentation data collection are completed by PLC controller, and the whole fermentation process is monitored in real time by operating computer (or man-machine interface), and the data are sorted and recorded. PLC is the first choice of process control system for small and medium-sized fermentation system because of its high reliability and cost performance.
Th-dcs biochemical process distributed control system is composed of lower computer and upper computer, which has the characteristics of centralized management and decentralized control. The control calculation and fermentation data collection are completed by the lower computer, while the upper computer monitors the whole fermentation process in real time, records, analyzes and prints the report forms. Due to the decentralized control, if the upper computer fails, it will not affect the control and data acquisition of the lower computer, and there is no problem of fault diffusion between the lower computer and the lower computer, which greatly reduces the probability of system collapse due to local fault.
