SG-820 vehicle speed monitoring system test device Introduction

SG-820 vehicle speed monitoring system verification device Introduction I. Overview SG-820 vehicle speed monitoring system test device, Zibo SEG Electronics Co., Ltd. independently developed with the latest ARM CORTEX-M3 core 32-bit microcontroller core of the intelligent of test instruments, with uCOS II real-time multitasking operating system for a variety of vehicles on the dynamic performance, safety performance, handling performance tests. 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. The system also comes standard with RS232 interface and USB interface 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 speed minimum resolution of 0.01 km / h. It can be equipped with Bluetooth wireless transmission function. SG-820 as a one-piece design, the standard built-in printer Second, the main test items overspeed test:? With specially designed large-screen LED electronic display, radar speed detection, and a variety of speed detection devices sense coil overspeed detection for examination. ? Brake test: Brake muzzle velocity, braking distance, braking time maximum deceleration, the average deceleration, MFDD (mean fully developed deceleration of) speed test:? Test distance, test time, average speed (in two start conditions, end four conditions combined into eight test method is flexible, can complete a variety of road tests). ?
