CXS-8F car driving recorder calibration device

Overview
The car driving recorder calibration device is an intelligent testing instrument independently developed by Zibo Chuangyu Electronics Co., Ltd. with a non-contact photoelectric sensor as the speed measurement unit. The real-time multi-task operating system is used to test various car driving recorders. Carry out actual vehicle testing.
The system uses a large-screen LCD display with Chinese character prompts to display multiple test data in real time. The curves are clear and intuitive. The instrument complies with the testing requirements of the automobile driving recorder and the automobile driving recorder calibration regulations. It is ideal for the public security traffic inspection agency of the measurement technology department. testing equipment.
The system's built-in micro printer can easily print out test results and test data dynamic curves.
The system is also equipped with a standard interface and memory card interface. Test results and data are stored in the card in the form of files. Users can use the system machine or laptop to easily perform secondary analysis and processing of the data.
This machine provides a level self-test signal output to perform simulated speed detection on the driving recorder.
Two main test items
Vehicle speed test, test distance, test time, average speed, minimum speed, maximum speed.
The road test continuously records the speed, distance, time and other parameters during the driving process of the vehicle. The driving recorder is used for real vehicle road testing of speed error and mileage error.
The simulation test outputs the simulated speed signal to simulate the speed error of the car driving recorder.
Positioning test: Calibrate the longitude and latitude positioning test time of the car driving recorder.
