used in automation and process control system. It can not only realize complex logic control, but also complete various sequence and timing functions. It has high reliability, good stability and strong anti-interference ability. The constant temperature vulcanization temperature control system takes PLC as the control core, through the real-time detection of the sensor, through the conversion processing of the temperature transmitter, takes the temperature as the parameter to adjust the speed of the motor and control the opening of the valve to meet the system control requirements. 1 principle of constant temperature vulcanization temperature control system of solid rocket motor see Figure 1 for constant temperature vulcanization temperature control system of solid rocket motor.

After casting, solid rocket motor is required to be vulcanized at a constant temperature of 50 ℃; After the grain is solidified and shaped, it is required to cool to room temperature (20 ℃) at a cooling rate of 0.5 ± 0.2 ℃ per hour. Due to the large height of the engine, the temperature field distribution in the upper, middle and lower parts of the engine is uneven. In order to control the temperature accurately and achieve constant temperature vulcanization, four temperature transmitters are set on the radial section of each part. The temperature transmitter is installed on the insulation layer to detect the temperature signal in real time, and send the temperature signal to
