The invention discloses a novel
alcohol test controller
system for an automobile. The
system comprises the automobile, an
alcohol controller and a single-
chip microcomputer, wherein the
alcohol controller is installed in the right-
hand position of an automobile cab driver, a palm sweat
alcohol content sensor is installed in an automobile
steering wheel and connected with the alcohol controller, the alcohol controller is connected with the single-
chip microcomputer arranged in the alcohol controller through an A / D (analog to digital) conversion circuit, the single-
chip microcomputer is connected with a
relay switch on the automobile, the alcohol controller is connected with an
alarm device, and the alcohol controller is connected with a
microphone. Through the structural design, the
system has the characteristics that the system can judge whether the driver is a drunk driver or not intelligently to guarantee the safety of the driver, the
workload of people such as traffic polices and the like is reduced, the alcohol sensor is high in sensitivity, the controller is small in size and low in
power consumption, a
voltage comparison function is provided, the manufacturing cost is lower than that of an expiration alcohol tester, implementation and use methods are simple and easy to popularize, corrupt practices, for example, replacement of the driver by other people for blowing and the like, are effectively prevented, and the system is high in reliability.
