Monitoring control system KNIKBIO-B

processindustrialautomatic

The KNIKBIO-S biological fermentation process control system is composed of the host computer, version 2019/2020, fermentation control software, field controller (BIO-S/Siemens pic), sensors and various executive components. The upper computer can use win7 or winlo operating system as the platform. The field controller is based on the German Siemens S7-1200 series programmable controller. It adopts multi-level expansion and has sufficient system A/D conversion channels, D/A/ conversion channels, and switch input and output. The field controller adopts the industrial- grade Siemens man-machine interface, and the fermentation system runs as usual without a host computer. Such a design structure and options better improve the reliability of the system, and will not affect fermentation production due to problems such as viruses or windows operating systems on the upper computer system. The software control system adopts an advanced embedded two-level computer network control structure based on industrial Ethernet. It includes a lower computer controller for field signal acquisition and conversion, an upper computer computer control, and network communication software. All aspects of control Adopt intelligent PID control, stable control, high control accuracy, and parameter self-tuning control algorithm. Man-machine interface The man-machine interface is friendly, and multiple monitoring screens can be switched; and the running status of multiple fermentation tanks can be monitored simultaneously on one display interface.
