The HRJY-A simple vehicle secondary maintenance inspection system is a handheld intelligent testing system independently developed by Zibo Hairun Electronic Technology Co., Ltd. The system uses an ARM microprocessor as a central control unit, and integrates sensors on the chip to complete the test. Various parameters in the high-speed acquisition test process are used to check the brake safety performance of the car, the luminous intensity of the light and the beam offset position, and the car. The front wheel side slip amount and the vehicle emission performance are integrated in the integrated design, which can realize the single item single-machine printing (57*60 small form), network printing (A4 report form), data saving and data uploading. The inspection system fully responds to the Ministry of Transport's 2016 Decree No. 1 for the inspection of the secondary maintenance of the operating vehicles. Meet GB/T18344, GB18565 and other standards. The system completely subverts the previously completed fixed-point positioning inspection method, which requires no special computer-controlled detection mode for follow-up inspection, which perfectly solves the problem of user detection of insufficient space. The powerful, low-cost test system with no site requirements provides the best service for car repair shops and 4S shops. The inspection system adopts a 320*240 color touch liquid crystal display and prompts Chinese characters. The detection process is clear, intuitive and easy to use. The test project adopts the menu-type operation, and the test results are automatically stored (a total of 256 sets of data can be stored) for later viewing and analysis of the test data. The inspection system is equipped with a standard RS232 interface, a built-in mini-printer, and the test results can be sent to the industrial control computer, controlled by the computer to form an online test system.
The whole machine adopts a portable design, compact appearance, external sensor is equipped with a powerful suction cup, easy to install, suitable for braking effect detection (MFDD) on vehicles with small space, lighting instrument communication using single-wire connection, can control the work of the light meter State, automatically receive the test data of the light meter and can realize the data save and upload. The side slide adopts the displacement sensor. The communication also realizes the single wire connection. During the detection process, the maximum sliding amount of the vehicle through the side slide can be monitored and saved. The filter paper smoke meter communication also achieves single-line connection, and automatic acceptance of the smoke meter test data can save the print upload.
