Video and diagnosing control system of medium voltage switch with embedded (MS-VDCS), and operation method

Abstract

The invention relates to the technical field of electric power control, in particular to a video and diagnosing control system of medium voltage switch with embedded (MS-VDCS). The system comprises a DCS (distributed control system) workstation, a DCS switch and a medium voltage switch control loop, and is characterized by further comprising a DCS embedded visual system and a diagnostic system; the DCS embedded visual system comprises a visual system switch and a plurality of cameras; the diagnostic system comprises a first DCS controller, a DCS communication card, a diagnosis management host, a diagnosis communication switch and a field testing system which are sequentially and electrically connected; the field testing system comprises a front-end measuring host and a plurality of front-end detecting elements; the system also comprises a remote control system; the remote control system comprises a DCS server, a second DCS controller and a DCS input / output (I / O) card. The invention also discloses a medium voltage switch state switching operation method. The system and the method have the beneficial effects that the field operation video and working state of the medium voltage switch control loop can be directly seen in the DCS workstation, and can be controlled; the system is stable in configuration and lower in cost.

Description

technical field [0001] The invention relates to the technical field of electric power intelligent control, in particular to a medium-voltage switch DCS remote visual stop and diagnosis system, and also relates to an operation method of the system. Background technique [0002] Process industry CIMS is a complex integrated automation system, which deals with all production activities of the entire enterprise. As an effective tool and means of realization, DCS completes important basic control and real-time production data collection, dynamic Monitoring and other functions. Compared with management computers, DCS can provide more reliable production process data, making the optimization decision made by CIMS system more reliable. [0003] From a functional point of view, the production automation system, dynamic monitoring system and online quality control in the process industry CIMS can all be realized by DCS. From the hierarchical structure of process industry CIMS, DCS i...

Problems solved by technology

[0005] Now the DCS equipment at home and abroad is very mature, but the DCS equipment adopts the protocol forms such as switch quantity, analog quantity, Profibus, FF, HART, etc. The form is too single, and it is still impossible to access the video and audio signals of the production site; and there are DCS Compatibility between the system and other non-system software is not conducive to the development and use of video and audio software; in addition, the use of conventional video and audio software requires the development of corresponding software interfaces for the DCS system, which affects the stability of the DCS system and makes it difficult to redevelop the software Very large; in order to ensure the control speed of the entire DCS system, the video and audio signals cannot be transmitted through the DCS internal network. In the overall network architecture, a switch of more than 10 Gigabit is required, and the cost is relatively high; in addition, if the video and audio signals are not transmitted If it is integrated into the DCS system, it needs to be operated separately, and linkage cannot be realized; especially for medium voltage switchgear
