Development of Low-pressure Control System Based on PIC16F877 Microprocessor / 医疗卫生装备

Objective To introduce an equipment of low-pressure control which is based on PIC16F877 microprocessor. The design flow and implementation methods are described. Methods The speed of motor was controlled to reach the set pressure value by PWM and the control requirements were achieved through human-computer interface. Results The setting value was quickly reached. Conclusion This device has interactive control and meets the requirements.
