The control system of vehicle inspection plays an important role in the digitalization and standardization of vehicle inspection. The paper is devoted to study the control system of vehicle inspection with centralized and integrated controller hardware. The system is capable of rapidly acquiring values to improve the error in side-slip testing. In addition, the dual-channel A/D converter is applied to balance the brake forces of both sides of braking equipments. The difference between the testing-time is reasonably downed in order to reduce the balance calculation error on the both sides of the braking force. The inspection system proposed in this paper uses a single computer to control the output of multi-view. A graphical user interface is also designed to replace the existing complex decentralized control system. This architecture could reduce the fault rate and increase the stability. Through a single centralized computer architecture, it reduces the number of computers and meets the requirement of energy saving and carbon reduction. The developed system practice in the vehicle inspecting outsourced factory, and complies with the standard of Directorate General of Highways. The sampling rate of side-slip testing obtains seven times per second by using the communications protocol proposed in this paper. Additionally, the hardware architecture proposed in this paper is applied to reduce the asynchronous sampling error and the amount of used computers.
Keywords: vehicle inspection, centralized control, A/D converter.
