Embodiment Construction

[0018] The invention discloses an object-oriented data exchange protocol DLT698.45 method for realizing real-time image transmission, comprising the following steps:

[0019] A. The trigger event is reported to the master station, and the location where the trigger event occurs is captured and stored in real time;

[0020] B. The image data is named according to the time sequence;

[0021] C. Encapsulate the image data packet and transmit the encapsulated image data packet to the concentrator;

[0022] The encapsulated image data packet includes the position of the image data corresponding to the capture device, the size of the image data, and the capture time sequence information, and the image data corresponds to the position of the capture device and the capture time sequence information in a one-to-one correspondence;

[0023] D. The concentrator reads the image data packet information according to the DLT698.45 protocol format; specifically: the concentrator defines each...

Abstract

The invention discloses a method for realizing real-time image transmission for an object-oriented data exchange protocol DLT698.45. The method comprises: firstly, reporting a triggering event to a main station; capturing and storing image data in real time at a trigger event occurrence position, naming the image data according to a time sequence, packaging an image data packet, transmitting the packaged image data packet to a concentrator, and finally, reading the information of the image data packet by the concentrator according to a DLT698.45 protocol format. According to the invention, theimage data transmission of the monitoring website can be clearly and completely realized in real time, the transmission data volume is reduced, and the stability and reliability of the whole data transmission process are ensured.

Description

technical field [0001] The invention relates to the technical field of power grid monitoring data transmission, in particular to an object-oriented data exchange protocol DLT698.45 for realizing real-time transmission of images. Background technique [0002] The monitoring of abnormal events in the power system involves all aspects, and now mostly adopts real-time monitoring or trigger monitoring. Among them, trigger monitoring is to set the trigger time threshold. Once a trigger event occurs, the network monitoring equipment will capture and transmit data. Since my country's power distribution network has the characteristics of many nodes, many branch lines, and many components, it is extremely difficult to accurately and timely realize the monitoring of each equipment network in each station area, and among them, for the capture There are many problems in the existing transmission method of image data because of the unclear network information and the large amount of data ...
