Automobile theftproof system based on dual central processing units

The utility model discloses an automobile theftproof system based on dual central processing units. The automobile theftproof system comprises a keyless access system, a remote controller, a radio frequency identification (RFID) system, a chip key holder and a starting system comprising a first central processing unit, an oil-electric control module and a starting circuit. The starting system also comprises a second central processing unit connected with the RFID system. Generally, the RFID system is in a rest and zero-power-consumption state. When the valid remote controller can not unlock the oil-electric control module, the second central processing unit can be actuated through short distance contact between chip key holder and the RFID system so as to unlock of the oil-electric control module. The power consumption and error probability can be reduced, and the first central processing unit can perform trouble-free operation for a long time. Even when the first central processing unit is invalid or the rem
