Industrial production in automatic control, in order to ensure production safety, or to product quality, temperature, pressure, flow, composition, speed, and so were some important control parameters, usually the need for automatic detection and monitoring in accordance with the results of the corresponding control. The automatic monitoring system, often with the limits of inspection, and automatic alarm system to alert operators of attention, if necessary, take urgent measures. Temperature is the object of industrial production was the main parameters of control. This paper describes the Vicat Jiangsu Fiber Co., Ltd. - Dafeng 35,000 tons of viscose fiber project in a drying system of temperature control system. The textile and chemical fiber in a drying system of temperature control system, mainly through GGD electrical control cabinet, and Zhejiang in the control of the DCS distributed control system, the scene of the thermocouple and to complete the electromagnetic valve, and a drying system to maintain the temperature To a certain extent, to meet production requirements. Key words viscose fiber temperature control GGD electrical control DCS distributed control system
