SG-820 non-contact multi-function speedometer

SG-820 non-contact multi-function speedometer Introduction I. Overview SG-820 series of non-contact multi-function speedometer, Zibo SEG Electronics Co., Ltd. self-developed high-performance British imports VBOX GPS sensor speed ranging unit, using Latest ARM CORTEX-M3 core 32-bit microcontroller core of the intelligent data processing test equipment, with uCOS II real-time multitasking operating system, using GPS Doppler velocimetry principle for dynamic performance on a variety of vehicle safety performance , steering performance, economic performance testing. The system uses 240 * 128 large-screen LCD display, character tips, real-time display a number of test data, curves, clear and intuitive. Test items using menu-driven operation, easy to use. Sensor coefficient and test parameters automatically stored non-volatile, without re-entering. Ergonomic machine design, easy to control, is an ideal teaching instrument automobile manufacturing industry, the automotive repair industry, automotive testing, research departments and farm machinery inspection departments ideal test equipment and vehicles in the institutions of higher learning. System built-in USB port and SD memory card interface, test results and data files stored on the SD card, to achieve unlimited data storage. Users to use the system or notebook computer can easily handle the data for secondary analysis. The system also comes standard with RS232 interfaces can be connected with an external micro-printer, easily test data and test curve printed. The speed minimum resolution of 0.01 km / h. Features: Based on a new area of ??high-performance GPS satellite positioning system development speed, displacement measurement system. Advantages: relatively non-contact speed sensor has a small size, easy installation, high accuracy, no calibration features. And all-weather test 24 hours, affected by rain, snow and testing environment, wide test range, thus greatly improving the efficiency of the test. Second, the main test items 1, taxi tests: sliding velocity, sliding distance, sliding time 2, the brake test: Brake muzzle velocity, braking distance, braking time, Coordinated Universal Time, maximum deceleration, the average deceleration, MFDD (full The average deceleration issued), the brake pedal force. Three test modes are available: pedal switch is triggered, speed trigger, trigger pedal force. 3, acceleration test: acceleration distance, acceleration time, speed and acceleration at the end of the shift operation is started and ending when the speed, distance and time. Four test modes, can accelerate the speed of one hundred kilometers hundred meters to accelerate, accelerate direct gear shift acceleration test. 4, the speed test: test distance, test time, average speed, minimum speed, maximum speed. Eight kinds of test modes are available: two kinds of start conditions, four kinds of end conditions and flexible combination of various test mode. 5. Road test: continuous recording speed of the vehicle during acceleration, travel distance and other parameters used for road traffic research department for traffic road safety research.
