Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The present invention will be further described with reference to the following examples.

Examples

A central signal management apparatus of the present embodiment, referring to fig. 1, includes a housing; the signal collector comprises a plurality of wiring terminals, and each wiring terminal is used for collecting an equipment signal; the central processing unit is internally provided with a plurality of signal channels which correspond to the wiring terminals one by one and used for processing equipment signals; the display establishes communication connection with the central processing unit and displays the processing information of the equipment signal; the warning indicator at least comprises a high-pitch device and a low-pitch device, and the high-pitch device and the low-pitch device are connected to the output end of the central processing unit through the driving circuit.

The signal collector is mainly used for sending signals including position signals, accident signals, forecast signals and the like to primary and secondary equipment in the transformer substation and inputting the signals to the central processing unit by adopting an independent channel.

Referring to fig. 2 and 3, a configuration interface is formed inside the display for displaying and monitoring the signal and status of each device, and the system parameter setting, the signal channel name setting, the signal channel status setting, the history viewing and the history clearing can be seen on the main interface of the display. The system parameter setting mainly comprises setting baud rate, time and other information; the signal channel name setting means that corresponding names are set correspondingly for all the connected channels; the signal channel state setting is a high-low sound alarm setting, a channel for receiving the advance notice signal is set to be high sound, and a channel for receiving the accident signal is set to be low sound; viewing and clearing the history is to view all past alarm records and clear all past alarm records that occurred.

Each page of the alarm display interface can watch the alarm information of 8 channels at most, and more alarm information can be watched through the previous page and the next page switching interface. Each alarm message will display a channel number and a corresponding channel name. The method is convenient for operators on duty to quickly search and confirm the abnormal occurrence point.

Wherein, signal collector, central processing unit are fixed to be set up in the casing, and display and attention device are fixed on the surface of casing, wholly are a main part.
