The automobile four wheel positioning instrument is used to detect the positioning parameters of vehicle wheels, and the design parameters are compared with the original plant to guide the user to the wheel positioning parameters.
To meet the requirements of the original design, to achieve the ideal performance of the car, that is, the control of light, stable and reliable, and reduce the bias of tire wear precision measuring instrument.
The main products on the market or CCD as the core technology products. CCD car four wheel positioning instrument is a data acquisition part of the four measuring probes. Coordinate measuring probe sensor (CCD) respectively induction relative to the measuring probe of the infrared emission tube light, via the wireless transmitter is transmitted to the cabinet in the wireless receiver, through the PC COM port transmission to the host computer, operation and processing. Due to CCD sensor which reflects the relationship between its own and corresponding measuring probe of the infrared emission tube, while the measurement probe by four wheel clamp and automobile wheel rim connected, so by 8 CCD sensor can measure the four rims in relation to each other, so as to determine the wheel alignment parameters; eight CCD sensors to form a closed quadrilateral, realize the vehicle four wheel alignment measurement. In practical application, 8 CCD sensors on 4 measuring probes are equipped with an optical filter to eliminate the interference of visible light on the image of the infrared emission diode.
The data processing part is the host of the four wheel positioning device, which mainly comprises a computer system, a power supply system and an interface system. Its role is realize user of four-wheel positioning instrument instructions. On sensor image data acquisition, processing, and with the original design parameters is displayed together, and to guide the user to adjust the wheel of the car, and finally print out the corresponding statements.
