AI Technical Summary

Problems solved by technology

During double-point synthesis, it may happen that the change of the switch is not fully in place, or the switch may have changed multiple times, resulting in redundant "intermediate states" during double-point synthesis, or when double-point synthesis Loss of intermediate definite states ("closed" or "open") transitions

Abstract

The invention discloses a double-point synthesizer, and aims to achieve the goal that the telemechanical apparatus does not lose the clear state of the switch or transmit excessive transient intermediate state when synthesizing a double-point signal. The synthesizer is provided with a real-time data processing module, a real-time data base and a double-point synthesizing module, wherein a change event processing module is arranged between the real-time data processing module and the double-point synthesizing module; a change event queue arranged in the change event processing module stores a dynamic process of switch nodes change as a change event record; and the double-point synthesizing modules extracts the change event record in the change event queue to synthesize a dynamic position signal of the switch. Compared with the prior art, the real-time data processing module in the invention detects the real-time state of the signal, updates the static signal condition in the real-time data base when the signal changes, adds the changed signal dynamic state to the change event processing module; and the double-point synthesizing module synthesizes the change dynamic signal in the extraction process. The invention has the advantages of no loss and no excessive transmission.

Description

technical field [0001] The invention relates to a power system communication device, in particular to a telecontrol device for substation communication. technical background [0002] In the substation monitoring system, the remote control device is responsible for collecting the data of all acquisition and measurement and control units in the substation, and uploading them to the remote dispatching system (including provincial dispatching, ground dispatching, etc.). With two-position switch position signals, it is very important for telecontrol devices to accurately reflect the status information of these signals. Ordinary open-in nodes have only two states: "closed" and "open", and this signal is called a single-point signal. The switch position is composed of two open-in nodes, one is "closing" and the other is "jumping". Through the pairwise combination of these two single-point signals, the actual situation of the switch is fully described: "closed", " Disconnected", "...
