Transmission Speed

Complex control system bears a heavy task, different field equipment have different requirements in reaction time, transmission speed, real time of fieldbus. Considering the characteristics of industrial Ethernet and fieldbus, mixed fieldbus was combined with Ethernet network; CAN - Ethernet gateway of CAN fieldbus was designed as example which can achieve the interconnection between upper and lower of the control system; the enterprise information network and control network got unified. Further, the system could integrate with internet to make it more practical.

Abstract In order to improve the refrigeration control efficiency and reduce the temperature fluctuation in the cold storage. In this paper, the refrigeration control system of the parallel unit of the cold storage is designed based on the upper and lower computers. The lower computer uses PLC to monitor the field parameters and control the execution of the field equipment. The upper computer uses HMI to realize the real-time monitoring, parameter display and alarm function during the operation of the cold storage, and uses the slide valve to adjust the energy of the compressor. The results show that the control system runs reliably and meets the control requirements of large cold storage.

Research And Design

Herein, a novel fuzzy PID temperature control system was proposed based on the technological process and control requirement of the crystal annealing furnace. Simultaneously, the electric control system was also designed with SIEMENS S7-300 PLC as the master controller. The results indicated that the system has the merit of rapid response time, low temperature fluctuation and all of the test items could meet the requirement of the actual utilization.
