Study On The Torsion-Angle Of Firearms Torsion Spring Measure And Control System

The passage introduces overall structure of torsion - angle of firearms automaton measurement system of firearms., the system hardware is regarded the micro processing control chip with AT89C52 and includes that stepper motor and stepper motor controller, light electricity code device and digital display, grating number are apparent table and torsion sensor and transmitter and the keyboard, LCD, A/D, I/O and serial port component. the torsion is measured in the reed sports course, namely measures the reed power - angle curve.
