SG-821 vehicle traveling data recorder testing equipment

Vehicle Recorder verification device Introduction I. Overview SG-821 car recorder verification device, Zibo SEG Electronics Co., Ltd. independently developed a non-contact speed sensor speed unit intelligent devices, the system uses 32-bit microcontroller processor with real-time multitasking operating system for a variety of car recorder simulation testing and real tests, instrument complies with GB / T 19056-2012 "car drive recorder" and JJG (Lu) 57-2007 "car tachograph "verification procedures meet the test requirements GB / T21861-2014 is the measurement technology department, public security traffic detection mechanism ideal testing equipment. The system uses a large screen LCD display, character tips, real-time display speed, distance, time and a number of test data, clear and intuitive. The system also comes standard with RS232 port and SD memory card interface, test data (speed, distance, time, etc.) are stored as files on the SD card, users use the system or a laptop can easily handle the data for secondary analysis. The speed minimum resolution of 0.01 km / h. Second, the main test items 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. ? Road test: the process of continuous recording vehicle speed, distance traveled, time and other parameters, for cars with logger speed error and the error of the actual vehicle mileage road test. ? Analog Test: a variety of analog velocity output signal, vehicle traveling data recorder simulation test speed error. Third, the technical performance indicators Power: Built: DC9.6v; External:???
