Acousto-optic alarm device

Abstract

The invention relates to an acousto-optic alarm device, which is used in the signal prompt alarm of a power dispatching automation system. Various signals are generated by the power dispatching automation system in the transformer substation operating process, and different voice alarms are send out by the power dispatching automation system according to the different signals; and monitoring staffs process the voice alarms after processing the voice alarms. The acousto-optic alarm device comprises an extraction module, a communication server, and an acousto-optic alarm terminal, wherein the extraction module is capable of extracting and sending signals corresponding to the voice alarms responded by the monitoring staffs, the communication server is connected with an extraction module, and is capable of transmitting signals corresponding to the voice alarms not be responded, and the acousto-optic alarm terminal is connected with the communication server, and is capable of sending the alarm signals; and the extraction module is arranged in the power dispatching automation system. As for the voice alarms which are not confirmed by the monitoring staffs in the existing power dispatching automation system, the acousto-optic alarm device provided by the invention can send alarms through a plurality of prompting modes so as to draw attention of the monitoring staffs, thereby processing the abnormal situations in time, reducing the working load of the monitoring staffs, and further ensuring the safe operation of a power grid.

Description

technical field [0001] The invention relates to an acousto-optic alarm device applied in the field of electric power engineering, that is, in an electric power dispatching automation system for signal prompting and alarming. Background technique [0002] With the development of the integration of dispatching and monitoring, the number of substations is also increasing, and the number of signals generated during the operation of substations is also increasing. The existing alarming methods for signals are mainly realized through the alarming service of the regional power grid dispatching automation system. The system alarm processing is used to process the alarm events that attract the attention of dispatchers and operators, including the processing of all alarm events such as changes in the operating status of the power system, future system predictions, equipment monitoring and control, and dispatcher's operation records. According to different needs, the alarm should be d...

Problems solved by technology

However, there is no separate reminder method for unconfirmed alarm signals. You can only check whether there are unconfirmed signals by manually looking through the records in the alarm window, which may cause omission of signals.

In addition, the current alarm is mainly broadcast by voice, which can easily cause noise in the dispatching hall

Moreover, the above-mentioned situation causes the monitoring personnel to be under a lot of pressure to monitor the screen, and the long-time monitoring work makes the monitoring personnel very prone to fatigue

In particular, the continuous voice alarms make the voices in the dispatching monitoring hall very noisy and interfere with each other, which can easily cause problems such as inattention, work errors, and even signal omissions.
