【摘要】 智能精密水压力发生器是重要的控制水压力的仪器。它可以取代常规的室内压力源；可以产生不同频率、不同幅度的动态水压力波形；同时可以根据设定的压力值进行水压力的稳态控制。本文就是根据实际情况，阐述了硕士论文课题工作中开发的水压力发生器的工作基本原理和设计过程中所涉及到的基本知识，并对关键环节进行了详细分析。 本文所述的水压力发生器是以单片机AT89C52为核心部件的工作系统，通过C语言编制的软件程序支持，能够对各种电信号进行处理、运算，继而驱动步进电机执行相应工作，实现对水压力的闭环控制。同时，对电机工作中出现的故障情况也可以做出紧急处理。本文还对单片机与PC机之间进行通讯、实施PC机控制的工作做了一定的研究和探讨。作为水压力发生器的PC机程序，采用Visual Basic语言编写；它能够对单片机发送命令信号，对水压力信号进行接收、显示，从而能够更加直观地观察到系统的工作情况；同时，能够保存数据，并自动进行数据分析处理。从而使整个测控系统更具数字化、智能化。 经过现场实际调试，运行结果表明：系统整体设计合理、性能可靠，实现了预期的设计目标。更多还原

【Abstract】 Intelligent precise water pressure controller is an important instrument of generating and controlling water pressure. It can replace the normal source of water pressure; It can generate dynamic water pressure which have different frequency and different range; It also can be set to generate static water pressure. To satisfy this kind of practical demand, this Master’s degree paper expatiates the basic theories and knowledge in designing the instrument that generate water pressure, which developed in the corresponding research subject. Details are provided at some key points.The MCU AT89C52 is used as a core component in this system. With the help of software programmed in C language, the system drives electromotor to execute relevant work after disposing and calculating each electric signal, and the controller becomes a closed loop system. It can deal with exigency when there is something wrong in this working system. Communications and PC controlling are also discussed in this paper, and certain research has been done. The PC software of this intelligent controller is programmed by Visual Basic language: It can send command signal to MCU and can receive and display the water pressure signal from MCU, so the system’ s working state can be watched more easily; At the same time , It can analyze and save the data automatically. So the whole control system becomes more digital and more intelligent.The debugging and running of the system indicate that the whole design is feasible and reliable, and the presumed functions have been conducted successfully.更多还原
