CTM-8A of non-contact speed tester

I. Overview CTM-8A of non-contact speed tester, Zibo Micro-Electronics Co., Ltd. independently developed high-performance microprocessor as the core of intelligent devices, to test the car dynamic performance, economic performance, handling performance testing. The system uses a liquid crystal 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 40 miniature printer, you can easily test results and test data, dynamic curve print out. And is equipped with a standard RS232 interface, test results can be sent to other computers, but also by the machine control system, complete the test project. Users to use the system or notebook PC easily the secondary analysis of data processing or storage. (Data Format Appendix) system to provide a "comprehensive test" test program, the flexibility to set the start condition and end condition tests, complete a variety of test items free, flexible and efficient. ? Second, the main test items taxi tests: sliding velocity, sliding distance, sliding time brake test: average deceleration brake initial velocity, braking distance, braking time maximum deceleration, the average deceleration, MFDD (fully developed? ) Speed ??Test:?? test distance, test time, average speed (minimum stable speed, the maximum stable speed) acceleration test: acceleration distance, acceleration time, velocity and acceleration at the end of the shift start and end speed, distance, time integrated? Test: two kinds of start conditions the four end conditions, flexible combination into eight test method can perform a variety of road tests. Third, the technical performance of the system power consumption:? Less than 10W (static power 5W) built-in power:? DC9.6v external power supply:? DC12V standard 9-pin RS232 interface?. (3 feet signal output, 2 feet signal input, 5 feet signals). 9600 baud, 8 data bits, 1 stop bit, no parity. ? Dimensions: 220X 200 X 70 mm Weight:?? 1 kg (including internal battery) Operating temperature: 0 ℃ ~ 40 ℃ Humidity:? 30% to 80% of project No. 1 Speed ??Range Resolution Accuracy 0 ~ 250.0 km / h 0.1 km / h 0.5% 2 distance 0 ~ 99999.999 m 1 mm 0.3% 3 times 0 ~ 99999.999 s 1 ms 0.1% 4 Deceleration 0 ~ 9.9 m / s2 0.1 m / s2 1% 5 MFDD 0 ~ 9.99 m / s2 0.01 m / s2 1% km / h: km / h m: m mm: mm s: s ms: millisecond m / s2: m / second squared km: kilometers (km)
