The Measuring System Of Torsion

The relation of torsion-angle is one of the most important static parameters of the gun.The paper introduces the design and components of the measuring system. At89c52 is used as a microprocessor in the system. The other components include step motor and step motor controller, photoelectric coder, torsion sensor, liquid crystal displayer (LCD), keyboard and serial port. The systematic parameters are stored in At24c64 produced by Atmel. The chip is a kind of serial E2PROM by I2 C, and the timing characteristics are simulated by software.The Visual C is adopted in the programming process. The measuring system has a good man-machine interlace, and is convenient to operate. The relating curve graph can be displayed in the dynamic way. The parameters set by the operator can be memori/ed automatically. The acquiring data can be exchanged with the main computer.
