摘 要
 本设计主要由两大部分所组成：镗床液压系统设计和微机控制系统设计。第一章主要介绍液压站的设计。为了满足机床对液压系统的工作要求，液压系统中采用双泵供油、多缸动作互不干扰回路，综合考虑选用液压元件、管件、标准紧固件，及电动机、油箱等。同时在设计此液压站时考虑到结构上的合理布置，以便于安装与维护。绘制液压站装配图时，应用CAD软件进行操作，方便快捷。
 液压站采用了单片机控制，此控制系统体积小、结构合理、工作可靠。本设计选用AT89C51作为主电路芯片，完成硬件线路和软件的编制。硬件电路设计主要介绍复位电路、电源电路、电磁阀驱动电路、显示电路等在电磁阀驱动电路中采用光电隔离技术，并利用达林顿管进行电磁阀功率的放大。在编制软件时采用模块化设计，主要包括主模块和子模块。

 Abstract
 This design is mainly formed by the two greatest parts: the poring machine hydraulic system design and the microcomputer control system design. The first chapter tells us the design of the hydraulic pump station. For satisfying the poring tool to the work request of the hydraulic system, the hydraulic system adopts the double pumps which provide the oil and many urns action with each other that not interfere the back track. The system chooses hydraulic components, tube pieces, standard tight firmware, the electric motor, oil tank and so on under the comprehensive consideration. Meanwhile designing this hydraulic pump station , the system considers the reasonable arrange on the structure for easily stalling and  supporting. When drawing the hydraulic pump station assembling diagram . I apply the software of CAD to carry on the operation. The operation is convenient and fast.
 The system uses the microcomputer control, this control system physical volume is small, the structure is reasonable and the work is credible. This design chooses to be the main electric circuit chip with the AT89C51, completing the hardware circuit and the establishment of the software. The article introduces the reset the electric circuit, the power electric circuit, the electromagnetism valve to drive the electric circuit, the show electric circuit and so on. The electromagnetism valve drive electric circuit utilizes the technique of insulation light. Furthermore, the circuit makes use of Da Lin Dun pipe to carry on the electromagnetism valve power's enlarge. The system adopts the module design while drawing up the software. It includes the main module and the son module.
