Embodiment 1

[0051] A schematic diagram of the broad area message transmission method provided by the present invention is figure 1 Show, including:

[0052] Step 1: Message sender checks whether the message receiver is online through the pre -deployed message management / distribution service;

[0053] Step 2: When the message receiver is online, the message sender sends the message to the message receiver in real time;

[0054] Step 3: Otherwise, the message sender sends a message to the message receiver after the message management / distribution service caches through the message management / distribution service;

[0055] Among them, message senders include devices or applications that need to send messages in the main station or sub -station, and message receivers include devices or applications that need to receive messages on the main station or sub -station.

[0056] Specifically, the wide -area message transmission architecture provided by the present invention consists of message manageme...

Embodiment 2

[0120] Based on the same invention idea, the present invention also provides a wide -area message transmission system for the main station. Because the principles of these equipment solve the technical problem are similar to the wide area message transmission method of the main child station, the duplicate is not repeatedly described.

[0121] The basic structure of the system is like Image 6 It includes: message sender, message receiver and message management / distribution service;

[0122] Message senders are used to query whether the message receiver is online through message management / distribution service. When the message receiver sends a message to the message receiver in real time, or send messages to the message management / distribution service when the message receiver is not online. Cache;

[0123] Message receiver, used to receive messages sent by message sender or message management / distribution service;

[0124] Message management / distribution service is used to store ...

Abstract

The present invention provides a wide area message transmission method and system for a main substation, including: a message sender queries whether a message receiver is online through a pre-deployed message management / distribution service; when the message receiver is online, the message sender sends the message to the message in real time. The receiver sends a message; otherwise, the message sender delays sending a message to the message receiver after buffering the message through the message management / distribution service; where the message sender includes the device or application that needs to send a message and is set on the master station or the slave station , the message receiver includes the device or application set in the master station or the slave station that needs to receive the message. The method and system mainly solve the problem of message transmission and interaction in a wide area such as substations and control master stations, and use an agent mechanism to build a message management / distribution service to realize maintenance-free access of message senders and message receivers, so as to achieve wide-ranging Domain-wide messaging.

Description

Technical field [0001] The present invention is the field of power automation technology, which involves a wide area message transmission method and system of the main child station. Background technique [0002] With the development of computer and network technology, the grid scheduling automation system has become more and more popular, and the coverage is continuously improved. However, with the continuous expansion of the system, more and more services to the power grid and the services provided. A large number of equipment and services require manual configuration, access and later maintenance requires a large number of personnel and time, and the difficulty of integration management has continued to increase. In order to cope with the growth of future equipment and service geometric types, you can learn from the "plug -and -play" theory in the computer field to realize the access to the power grid scheduling automation system of the power grid device, that is, plugging in ...
