Research and Implementation of Digital Two-dimensional Inclination Measurement System

The camber and toe of the four-wheel alignment technology are very important for the smooth operation of the vehicle. A digital two-dimensional angle measuring instrument is designed to measure camber and toe in this paper. The instrument consists of a hand-held terminal and a two-axles inclination sensor. Hand-held terminal is used for data processing. MSP430 is used as the control unit, and the power supply, human-computer interaction, data storage, data communication and other circuits are designed. Inclination sensor is used to measure data. By practical testing, the instrument can accurately measure the four-wheel inclination angle, which is convenient to assist the four-wheel positioning. In the engineering application, it reduces the labor cost and realizes the miniaturization and family of the measuring instrument.
