Abstract

One or more embodiments of the invention disclose a multi-mode redundant swing rod control electrical system based on optical fibers. The multi-mode redundant swing rod control electrical system comprises a central control cabinet, a near control cabinet, a remote control cabinet, control software and other electrical elements, wherein the remote control cabinet is connected with the near control cabinet through an optical fiber to realize real-time monitoring and emergency remote control, the central control cabinet comprises a launch console and a relay cabinet connected with the launch console, the near control cabinet is connected with the relay cabinet of the central control cabinet, the other electrical elements comprise an electromagnetic valve, a limit switch and a pressure sensor which are respectively connected with the near control cabinet, and the near control cabinet controls a related controlled object to complete a swing rod action, feeds back a swing rod in-place signal, collects pressure information and uploads system information. According to the invention, the reliability, the maintainability and the interchangeability of the system are improved through a full-system redundancy control technology, an explosion-proof design and a full-isolation access control technology.

Description

technical field [0001] This document relates to the technical field of electrical control, in particular to an optical fiber-based multi-mode redundant pendulum control electrical system. Background technique [0002] At present, the cable swing rod is mainly used to horizontally support some cables and plugs of the control system and the safety system. Designing the electrical system of the cable swing rod can realize the function of swinging the swing rod open, swinging back, and automatically returning the response signal. Therefore, the control electrical system has the following requirements: After the control signal arrives, the cable pendulum can be opened sequentially or at the same time, and the time for the pendulum to turn from horizontal to vertical position is not more than 10s; the emergency remote control pendulum can be realized simultaneously or individually The expansion and swing of the root; for the convenience of observation, it is necessary to design a...
