Problems solved by technology

Generally speaking, the background monitoring system has the function of switching and calling the fixed value area of ​​each protection device independently, but there are few functions that can switch the fixed value area of ​​multiple devices sequentially and in batches. In actual engineering applications, this The simple single-device control method is far from meeting the actual needs, and more and more applications need to connect multiple devices together for sequential control (or more complex logic control)

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] (1) Object-based program-controlled data definition and structure design.

[0028] A well-designed data organization method can provide better support for the sequential switching of the program-controlled function modules in the fixed value area, and as the basic interface of the program-controlled function, the logical design of the data organization also enhances the scalability of the program-controlled function. The data organization design of the program-controlled function data organization based on the sequential switching of the fixed value area includes the design of the object type (only the attribute definitions related to this application are given, and the format is: object->attribute) and the design of the hierarchical relationship between types.

Abstract

The invention discloses an object-based fixed value area sequential switching program control method. The actual use of the method in engineering greatly improves operation efficiency and effectiveness. The basic unit of a SCADA monitoring system platform data organization is object. The data and relations between the data in the system are distributed in various object types of cases in the form of objects or object attributes. Each object case is numbered by a unique ObjectId. In combination with a graphic tool, the platform system displays data to a user in the form complying with the actual topological structure, thereby greatly improving the data management capability of a large SCADA system.

Description

technical field [0001] The invention relates to the SCADA distributed platform automation industrial control industry, in particular to an object-based fixed value area sequence switching program control method. Background technique [0002] In the integrated power monitoring system, many protection, measurement and control devices are used. The data of the protection device is generally uploaded to the background monitoring system through the 104 protocol, and the background monitoring system can also send control commands to the protection device through the 104 protocol. Generally speaking, the background monitoring system has the function of switching and calling the fixed value area of ​​each protection device independently, but there are few functions that can switch the fixed value area of ​​multiple devices sequentially and in batches. In actual engineering applications, this The simple single-device control method is far from meeting the actual needs, and more and m...
