The invention provides an automobile driver and passenger sitting posture monitoring system which comprises a headrest pressure sensor, a backrest film type pressure sensor array, a cushion film type pressure sensor array, a seat backrest angle sensor, a microprocessor and an upper computer. The headrest pressure sensor transmits a pressure signal to the microprocessor through the voltage division circuit, the signal conditioning circuit and the AD converter in sequence, and the seat backrest angle sensor transmits an angle signal to the microprocessor through the voltage division circuit, the signal conditioning circuit and the AD converter; the backrest film type pressure sensor array and the cushion film type pressure sensor array transmit pressure signals to the microprocessor through a signal conditioning circuit and AD conversion, and the upper computer is connected with the microprocessor. According to the invention, microprocessor control ports are saved, hardware cost and space of a data acquisition system are reduced, the system can be conveniently applied to automobile seat body pressure detection, the detected area is large, measurement is flexible and convenient, and data acquisition precision and speed are improved at the same time.
