| 【摘要】液压支架是煤矿井下综采工作面的关键支护设备，研发新型液压支架试验台测控系统对液压支架性能的提高至关重要。 在分析液压支架试验台的结构功能以及GB25974.1-2010煤矿用液压支架通用技术条件的基础上，使用工控机直接参与控制。分析测控系统的工作流程，根据液压系统对硬件进行选型设计。以模块化软件设计思想为指导思想，分析软件的需求，从而确定软件的构成。32074 在对电气控制部分分析后，我们设计出了电机启停电路控制液压泵，各部分供电电路，增压缸及系统自动转换控制电路。 在硬件总设计方案的基础上对硬件系统进行了开发。首先根据安全性、实时性和可靠性的要求，进行了硬件的选型；然后对电磁阀控制回路进行了设计与实现；分析了系统干扰的来源，并采取了相应的抗干扰措施。 对测控系统软件部分进行了开发，在对试验进行分析后我们首先建立数据库，给出软件构架，利用VB6.0开发人机界面，给出程序框图并编写代码 。 【毕业论文关键词】：液压支架试验台，工控机，测控系统，电气控制 Design on the computer measurement and control system of Hydraulic support test stand 【abstract】Hydraulic support is the key of the coal mine fully mechanized working face support equipment, research and development of new type hydraulic support test rig measurement and control system is very important to the improvement of the performance of the hydraulic support. On the analysis of the structure and function of the hydraulic support test rig and GB25974.1-2010 for coal mine hydraulic support for general technical conditions, on the basis of using industrial computer directly involved in the control. Analysis of the working process of the measurement and control system, according to the selection of hydraulic system for hardware design. The guiding thought of modular software design thought, analysis software requirement, to determine the composition of the software. After analyzing the electrical control part, we designed the control hydraulic pump motor and a power outage road, each part of the power supply circuit, pressure cylinder and automatic conversion control circuit system. On the basis of the total design scheme of hardware for hardware system development. First according to the requirements of safety, real-time and reliability, the hardware selection; Then on the solenoid valve control circuit design and implementation; Interference sources of the system are analyzed, and the corresponding anti-interference measures. Has carried on the development of measurement and control system software part, we first set up after the analysis of test database, software architecture is given, using VB6.0 by use the development the man-machine interface, program block diagram and coding. 【Keywords】Hydraulic support test rig, industrial control, measurement and control system, electric control 目录 第一章 绪论 1 1.1课题背景、目的和意义 1 1.1.1课题的背景 1 1.1.2课题的意义 1 1.2支架试验台测控系统的发展概况。 1 1.2.1液压支架简介 1 1.2.2液压支架试验台测控系统 1 1.3本课题主要研究的内容 3 第二章 液压支架试验台计算机测控系统总体设计 5 2.1概述 5 2.2试验台结构及其参数 5 2.2.1试验台主体结构 5 2.2.2试验台参数 5 2.3液压支架试验标准 6 (责任编辑：qin) |
