For the issue of high temperature of crew compartment in armored car, semiconductor temperature control system based on AT90CAN32 was designed . The system uses AT90CAN32 SCM as Controller Unit , using multiple DS18B20 temperature sensor to constitute a distributed refrigeration nodes, using the existing CAN bus resources to control temperature for each refrigeration nodes in armored car. Neural network PID algorithm was applied in parameter tuning. Adjusting PWM wave pulse width to control the working state of semiconductor refrigeration piece . At an expected temperature , the cooling experiments were conducted and the test results were obtained. Experimental results show that a stable and reliable system can achieve the expected cooling performance.
