Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0053] A safety control method for a catenary isolating switch monitoring system. The final blocking state is identified based on the blocking combination relationship. The blocking combination relationship is realized through a configuration table format. The configuration table includes source entry attributes and target entry attributes. The source attributes include blocking equipment numbers, The opening and closing points of the lock and the opening and closing positions of the switch points, the target entry attribute remote control equipment number, remote control switch number and group number; the group number indicates the logical relationship of the target entry;

Abstract

The present invention provides a safety control method and system for a catenary isolating switch monitoring system. The digital communication remote control locking function avoids the possibility of misoperation of the catenary isolating switch due to unsatisfied on-site operation conditions. The locking function of remote control is introduced by the centralized monitoring device on the centralized monitoring screen, and whether there is a locking signal is identified through the combination of opening and closing points of the locking. The centralized monitoring device sends the state of the virtual locking remote signal point to the isolation switch RTU (Remote Terminal Unit) through the GOOSE network, and dispatches the unlocking signal to be sent directly, so that the remote RTU is not controlled by the locking signal, which greatly reduces the risk of misoperation Probability, the centralized monitoring device, scheduling, and integrated self-background are all in parallel positions, and they all communicate directly with the isolating switch RTU, and the isolating switch RTU adopts a direct control RTU device. The solution to reduce fault points can effectively prevent the isolating switch from refusing to operate and remote signaling False positives.

Description

technical field [0001] The invention relates to the field of a catenary electric isolating switch monitoring system in the railway industry, in particular to a safety control method and system for a catenary isolating switch monitoring system. The invention supports GOOSE input and output functions, and realizes digital communication locking and screen control functions through the IEC61850 protocol. Background technique [0002] The catenary isolating switch is one of the important electrical equipment of the electrified railway power supply system, mainly used for catenary fault removal, segmental power outage maintenance, segmental power outage operation and changing power supply operation mode, etc. In order to make the catenary isolating switch operate reliably and ensure the safety of electrified railway operation, it is very necessary to incorporate some important catenary isolating switches into the telecontrol monitoring system. At present, the remote control of ca...
