Using special high temperature thermocouple, micro-pressure transmitter signal acquisition tunnel kiln temperature and pressure of the measuring point, calculates and processed by imported PLC, temperature controlled by a dedicated software, the parameters collected using traditional PID operation with advanced the fuzzy control theory control; through PLC control inverter wind and automatic transfer device supplementary cast coal combustion, according to the theoretical curve to achieve the purpose of automatic roasting, baking tunnel kiln to achieve standardization management, digitization and automation.

Main Functions:
1. Draw tunnel kiln calcination real time and historical curve;
2. Temperature and pressure abnormal alarm;
3. automatically adjusts air flow by adjusting the frequency converter molestation;
4. Control Automatic cast coal device automatically cast coal;
5. Automatic identification of qualified firing bricks, sound and light alarm for moving out bricks;
6. Record each production run parameters such as temperature, pressure, and number of bricks,etc.
