Design of steering angle detecting system based on wireless communication

In this study, the detecting device of the steering angle is designed based on the single-chip microcomputer of STC12LE5A60S2 and the wireless communication module of ZICM2410; the hardware structure design and software implementation of the device are proposed. With this detecting device the steering angle can be detected any time which can be shown on the LCD board of the detecting device, and on main controller through the wireless communication; the rules can be modified in the condition of zero drift to ensure a continuous trouble-free operation with high degree of accuracy; the performance detection index is the evidence to judge whether the car is qualified or not. Less cost, greater reliability, flexibility and convenience are the main features of this device.
