摘　　要：本文对熏洗床的压力控制进行了研究,开发了一个以ADμC812单片机为控制核心的集喷洗压力的测量、处理、显示、自动控制为一体的闭环微机控制系统。采用C51编程语言对控制系统进行程序设计,包括主程序、外洗控制子程序、按键处理子程序等,采用积分分离的PID控制算法实现对喷洗压力的控制,既保持了积分作用,又减小了超调量,提高了压力控制精度。This article focuses on the pressure control of the washing spray therapy apparatus by developing a closed loop computer control system which can measure the washing spray pressure, display and process the data.the ADμC812 was utilized as the core of the automatic control system.the C51 programming language was adopted to design the control system software, including main program, washing control, key - press disposal etc. By using the PID control algorithm with integral separation to control the washing spray pressure, the integral role can be maintained and the overshoot can be reduced simultaneously and the precision of pressure control can be enhanced.

关 键 词：熏洗床 ADΜC812单片机 自动控制 积分分离的PID
