Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] At present, the bus system can be divided into two types: open source and non-open source. The open source bus system provides a complete code project, allowing users to understand the detailed communication process, and can facilitate porting and development on different platforms. Non-open source systems provide compiled program modules for developers to develop and use in a specified environment. Specific implementation reference figure 1 , including three processes: 1. Construction of the basic software and hardware operating platform; 2. Design and development of the virtual slave station system; 3. The use of the virtual slave station system, that is, the development of the logic test program.

[0037] Here, taking the open source bus system Ethernet PowerLink as an example, the method of implementing the test for the control system using ...

Abstract

The invention discloses a semi-virtual functional test device and method for a control system. According to the method, in detail, a plurality of virtual slave station nodes are established in a real-time operation system of a computer to replace real slave station nodes and connected with a master station of the system to be tested through bus communication interfaces. Meanwhile, in a general operation system operating on the computer in parallel, and a software programming interface development procedure provided by virtual slave stations is used for achieving monitoring and a performance analysis of bus data and simulating functions of user input or device input, so that full-automatic testing is performed on the control system. Needed hardware is only one computer with the specific communication interface, and the general operation system and the real-time operation system operate on the computer in parallel. The semi-virtual functional test device and method have the advantages of being low in cost, high in testing efficiency and the like, can be suitable for developing, commissioning, functional testing and other testing occasions of the control system, and have good practical value and application prospects.

Description

technical field [0001] The invention relates to a semi-virtual control system function test device and method, which can be applied to the function test occasions of various bus-type control systems. Specifically, it can be used for the testing of the control system during the development process, the acceptance test of the control system when the control system is completed, and other processes. Background technique [0002] The control technology of automation equipment is advancing day by day, and the control system is required to have more and more distributed and reconfigurable functions. Therefore, the bus control system has gradually become the primary consideration system for engineers. At present, the bus control system has been successfully applied in rich and mature fields such as process control and motion control, and the structural characteristics of the master-slave distribution of the bus control system have solved many problems that cannot be solved by the i...
