The LPT Data Acquisition Card Design of the Front-Wheel Vehicle Positioning Test Equipment Based on the I2C Bus

This paper describes the acquisition system hardware and software to achieve methods, not changes in hardware equipment, printing equipment from the existing population data collection methods. Systems designed with advanced I²C bus (smart internal bus) technology, the data collected by the existence of large-capacity memory, in the spare time to deal with good data sent through the serial port to the PC, PC to multiple devices data acquisition and processing system. The application of the system, the existing car manufacturing industry in the early part of the testing equipment data collection network has provided technical support.
