Mitsubishi Q the application of PLC in the tunnel drying oven machine equipment

Abstract: the tunnel oven machine is used for heating of the Q PLC tunnel oven machine Mitsubishi glass Q PLC tunnel oven machine Mitsubishi fiber, system requirement for the temperature control is higher, so the system is to adopt PID temperature control. The whole system working principle is as follows: first of all raw materials through the rail car to the tunnel, the gate began to close, stay gate began to open the valve fully closed steam for heating, because of the glass fiber can't be a thermoforming, 15 heating section step by step, so the whole heating process points per period of temperature to the requirement of temperature is different, in order to system is more reliable, each section of the tunnel is installed the upper and lower two temperature sensors, temperature sensors to detect the Q64RD temperature is converted into electrical signals sent to the temperature of the module, the temperature value to set the PLC data storage of D, the PLC receives two average temperature, the average temperature and temperature set point, and according to the set of PID parameters PID arithmetic, at last, by Q68DAI modules to convert the output of the obtained PID arithmetic control MV into current signal, is used to control the valve opening, so as to achieve the purpose of temperature control, for a total of 15 period of heating, a total of 15 PID loop, so the whole system control principle of each loop is the same.

A total of 12 kinds of tunnel oven machine set, 12 sets of tunnel oven machine through the Ethernet connection into a system, high-speed data transmission through Ethernet can up a machine, reach the upper machine for the purpose of real-time monitoring system.
