Abstract

The paper has briefly introduced the design method and the working principle of strip cutting machine. System is provided with LCD display, motor show, a deferred action sets, numerical memory, test strips full State, set the length of processing and control functions. System is with STC89C52RC single-chip as the core, adopting CS1621 LCD, matrix press, Hall-effect magnetic sensor, switch, alarm circuit, EEPROM memory and speed-regulating motors and other parts of the hardware circuit have completed its length, set the length and the volume display and adjustment of the motor speed, While I have cmpleted all the peripheral hardware of the control system circuit , schematic and PCB design contained , written system software sequence range, finally I have completed the online debugging, making the system meet design requirements.

Key words: Single-chip Microcontroller ; Strip cutting machine; motor speed matrix keys;
