Design of Calibrating Apparatus of Motorcycle Road Test Instrument Based on MSP430

Abstract:

At present, there are various types of motorcycles road test devices, but the corresponding calibrating apparatus are lacking in our country. A calibrating apparatus of motorcycle road test device was designed. MSP430 was used as control unit. The timing square wave generated by Timer B outputted by the I/O port was taken as the control signal of the stepping motor, and the control signal drove the stepping motor through the L297 and L298N chips. At the same time, four buttons were used to control the status of the motor, and an AMPIRE-12864 was used to display the real-time data of speed of stepping motor measured by the photoelectric encoder. The system software was implemented by C language under the environment of IAR for MSP430, and the system overall and module simulation were implemented under PROTUES software environment. Finally, the calibrating test was conducted. The results prove this apparatus can obtain the anticipant effect.
