Abstract: In the industrial production of wire rod, wire diameter measurement is a very important part. In order to improve the efficiency of on-line diameter measurement, it designs an on-line diameter measurement system which based on the ARM, optical system and CCD. Through the ARM processor drivers the CCD and processes deferent signal of the CCD, it implements the high-speed on-line measurement of the wire diameter. The applications of μC/OS-ІІ embedded real-time operating system improve the scalability and stability of the system. The system has many advantages such as fast detection, high reliability, non-contact measurement and so on.
