The invention discloses an air inflation and deflation system based on the automatic detection of tire pressure and tire temperature of automobiles. The air inflation and deflation system comprises a wireless power generation coil device, a small-sized air pump, a normally closed solenoid valve, a micro-battery, a wheel-pressure sensor, an infrared temperature sensor, a SCM (single chip microcomputer) main controller, a SCM auxiliary controller and a SCM wireless module, wherein the wireless power generation coil device, the micro-battery and the small-sized air pump are arranged on an automobile rim, the wheel-pressure sensor is arranged on a valve core of a tire, and the infrared temperature sensor is arranged on a frame and is just opposite to the side face of the tire; and the micro-battery supplies power to the tire pressure sensor and the infrared temperature sensor, tire temperature information produced by the infrared temperature sensor is sent to the SCM main controller, tire pressure information of the tire pressure sensor is sent to the SCM auxiliary controller, and the SCM auxiliary controller sends the tire pressure information to the SCM main controller by the SCM wireless module so as to further control the operating of the wireless power generation coil device and then supply power to the small-sized air pump or the normally closed solenoid valve, thereby achieving the purpose of air inflation or deflation.
