To solve the problem of crew compartment temperature control of the armored vehicle, the thesis design a semiconductor temperature control system based on CAN bus. The system uses AT89S51 as a controller and multi DS18B20 sensor composing make up of distributed refrigerant node, the existent CAN bus of armored vehicle also be utilized to control the refrigeration node in vehicle. It also uses an increment PID algorithm to modulate width of pulse so as to control the work estate of the semiconductor cooling piece. Carry through refrigerant experiment for eighty minutes based on an assumed temperature. Experiments results show that the system is stable and reliable, the cooling effect reach to our expectations.
