【摘要】液压实验台是液压传动课程中十分重要的实验设备,该设备对于本科生的教学实验、科研人员的实验研究具有重大的作用与意义。
摘要计算机自动控制液压综合实验台测控系统是液压试验的辅助工具。根据液压试验系统设计了测控模块的总体方案,包括电控系统和数据采集与转换。
在电控模块的设计中,根据液压系统中需要控制的电气元件,设计了电动机的启停控制电路、液压系统中手动与自动转换控制电路、叶片泵的起保停电路等;在数据采集与转换模块的设计中,根据数据转换类型的不同,设计了相对应的采集与传输方式。以实验室环境为前提对电气元件进行了选型。依据元器件的尺寸与相互之间的连接方式,设计了控制台面板布置图和外形图。
在软件的设计中,依据实验要求设计了软件框架与程序框图。并利用C#语言编制了测控软件,实现了对液压系统的控制。根据测控软件安装与调试时需要注意的事项,详细编制了安装的步骤与调试的方法。26158

Hydraulic comprehensive test bench measurement and control system design of the computer automatic control
[Abstract]Hydraulic experiment platform is a very important experiment equipment in the hydraulic transmission course,it plays an important role for the teaching of undergraduate and experiment.
Computer measurement and control system is an auxiliary tools in the system of hydraulic automatic control.According to the overall scheme of the hydraulic experiment system,measurement and control module is designed, including the system of electronic control and data acquisition or conversion.
In the design of electronic control module, according to hydraulic system,the motor control,the manual and automatic switching control of hydraulic system,the vane pump,s control are designed. In the design of data acquisition and conversion module, according to different types of data conversion, I design collection and transmission mode .On the premise of the lab environment, electrical components are selected .According to the size of components and the connection between each other, the console panel layout and appearance is also designed.
In the design of software, according to the experiment requirement,I design the diagram of the software framework and procedure ,compile the measurement and control software by C# language , realizing the control of the hydraulic system.According to the measurement and control software installation and debugging matters, I designed the steps of installation and the methods of debugging carefully and we need to pay attention to it.
