Provided is an automatic detecting system of an automobile seat heating cushion controller. The automatic detecting system uses an upper industrial control computer as the control core, and uses an interface board as a transferring unit of a controller, and simulates various work scenes through intelligent devices like a programmable power supply, a programmable electronic load and others, and completes the measurement of various work states. Through the control of the software, the system can complete the measuring tasks of normal work state, overvoltage detection, under-voltage detection, over-current detection, temperature saturation detection, and overload detection. After detection, the bar code printing can be automatically completed, and the detection result can be recorded into a system database. Through actual test, the automatic detecting system of the heating cushion controller increases the product detection precision and greatly improves enterprise product detection efficiency.
