| Abstract:—Industrial automation control has been widely used in the chemical production process. The rapid development of wireless communication technology can realize the wireless transmission of data signals between instruments. In this paper, the wireless transmission module was applied to the distributed control system (DCS) of chemical production to realize the design of chemical wireless distributed control system and also applied to the glycine production process control system. Besides, some switch control in the process flow of the distillation tower control equipment was simulated and tested to achieve the expected results. The result shows that the real-time database includes graphic display, data report, historical report, and historical database data, which are interconnected with the communication management module; through the wireless DCS, the management protocol is used to realize the freedom of communication between all connected devices, and the operation and production process control of the chemical wireless DCS is not affected by the system device failure. |
