【摘要】：本课题源于一个实际科研项目。该项目主要是研制液压元件/传动部件综合性能试验系统。试验内容包括典型液压阀、液压泵、液压马达、液压缸和专用传动部件的动、静态性能试验。该试验系统结合了液压传动、自动控制、信号检测、数据库设计、工控机和PLC系统等多项技术。本课题负责人机交互设计与数据库设计。对于试验系统来说,人机界面设计和数据库设计是整个项目中的重要一环,其意义关系到整个项目的质量,一定要做好这项工作。本论文首先介绍了目前常用人机交互与数据库软件设计平台的方法,并选择适合本试验的方法；其次,人机交互设计与数据库设计都是以试验规程为出发点。在这里以液压缸试验规程为例详细说明人机交互界面和数据库的设计依据。依据试验规程,用WinCC完成了人机界面设计。其中包括登录界面、主界面(用于选择试验)、各试验单元界面。人机交互实现的功能有用户管理功能、试验系统动态显示、试验数据的处理、试验数据的存储。WinCC与PLC之间的通讯是人机交互的基础,通讯方式是设置相应的过程变量。在数据库设计中,本文以Access为软件平台,根据试验需要建立相应的Access表。在数据库设计中,本文利用VB6.0访问数据库的方法,采用VB中的控件实现WinCC中报表打印、历史数据查询和系统管理功能。完成人机交互与数据库设计后,在试验室内对系统进行了调试,初步验证了上述设计的可行性。
[Abstract]:This subject originates from a practical scientific research project. The project is mainly to develop hydraulic components / transmission components comprehensive performance test system. Test contents include dynamic and static performance tests of typical hydraulic valves, hydraulic pumps, hydraulic motors, hydraulic cylinders and special transmission components. The test system combines hydraulic transmission, automatic control, signal detection, database design, industrial control computer and PLC system. This subject is responsible for the design of human-computer interaction and database. For the test system, the design of man-machine interface and database is an important part of the whole project, and its significance is related to the quality of the whole project. Firstly, this paper introduces the methods of human-computer interaction and database software design platform, and selects the method suitable for the experiment. Secondly, the human-computer interaction design and database design are based on the test rules. The design basis of man-machine interface and database is explained in detail by taking hydraulic cylinder test procedure as an example. According to the test rules, the man-machine interface is designed with WinCC. These include login interface, main interface (for selecting test), each test unit interface. The functions of man-machine interaction are user management, dynamic display of test system, processing of test data, communication between WinCC and PLC is the basis of man-machine interaction, and the communication mode is to set corresponding process variables. In the database design, this paper takes Access as the software platform and establishes the corresponding Access table according to the need of experiment. In the design of database, this paper uses VB6.0 to access the database, and adopts the control of VB to realize the functions of report printing, historical data query and system management in WinCC. After completing the design of human-computer interaction and database, the system was debugged in the laboratory, and the feasibility of the above design was preliminarily verified.
