Design of Test System for Motorcycle Speedometer

A kind of motorcycle speedometer test system is introduced. Based on industrial computer, plug-in data acquisition card, photoelectric encoder, frequency converter and roller test bench, real-time acquisition of motorcycle actual speed is realized and according to GB7258-2004, motorcycle speedometer is evaluated to supply a basis for safe operation and speedometer calibration. During the test process of speedometer, the operator can control motorcycle speed at any stable value with a speed regulation box and complete the test without any other auxiliary staff. Compared with the instruments used in real road test of speedometer, this test system not only simplifies the operating process, but also makes the test result more accurate and reasonable.
