A substation information push system

technical field

The invention belongs to the field of intelligent substation information service management, and in particular relates to a substation information push system.

Background technique

With the development of network technology, real-time feedback of smart substation operation information to relevant units has attracted more and more attention from relevant departments. During the operation of the substation, in fact, the relevant units have been disconnected from the substation. If the device fails or trips, this situation can only be handled manually by the staff of the monitoring master station, and the relevant units are organized to analyze the reasons. How to know the operation status of the devices you care about in the substation in real time requires a mechanism to push the operation information of the devices in the substation to relevant departments in a real-time, accurate and targeted manner through push service technology.

In order to solve the above technical problems, the substation information push system of the present invention includes an information processing module, an information push module and a network sniffing module configured according to the substation communication protocol. Send the information, and store the obtained information into the original message buffer of the system; the information processing module is used to filter and classify the information stored in the original message buffer of the system according to the message type and the message protocol feature word and format conversion and adding to the corresponding push queue; the information push module is used to read information from each push queue according to the information subscription list customized by different clients, and push it to the corresponding client.

The system also includes a client connection detection and maintenance module for establishing and maintaining a long connection with the client.

The system also includes a push information customization and display module, which is used to prompt the user to log in or use the logged-in account to actively try to connect to the server. For users who successfully connect to the server, modify and update the user-customized information subscription list and highlight the period when the user is not online Substation information pushed by the system.

The information pushing module adopts multi-thread technology when pushing information to each client.

The system also includes a historical push information database for storing information that has been pushed to all target clients.

The message type is an event type, and the message protocol feature word is a device address, an IED name or a data set.

Beneficial effects of the present invention: the present invention captures the protocol message by starting the network message sniffer, and the information processing module performs operations such as filtering, classifying and processing conversion of the message, and enters different message types according to the information type and message protocol feature word The queue is managed, and then pushed to the client through the information push module, which realizes the timely feedback of substation operation information and establishes a more complete substation service management system.

The present invention uses multi-thread technology, each thread processes a receiving queue, and sends data to the corresponding client through the long connection data transmission channel, and the client performs display and analysis after receiving the information.

The present invention is based on network message sniffing and active push technology of long-connection service information, and pushes relevant device information to corresponding clients in a real-time, accurate and targeted manner through the substation service system for the information concerned by manufacturers or relevant departments. It provides a means for manufacturers and operation and maintenance departments to keep abreast of the operating status of the device.

detailed description

The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the information push system of this embodiment includes a network sniffing module, an information processing module, and an information push module, wherein the network sniffing module is used for real-time acquisition of information sent by devices in the substation to the monitoring master station , and store the obtained information into the original message buffer of the system; the information processing module is used to filter, classify and format-convert the information stored in the original message buffer of the system according to the message type and message protocol signature, and then add it to the The corresponding push queue; the information push module is used to read information from each push queue according to the information subscription list customized by different clients, and push it to the corresponding client.

The functions of each module in the above-mentioned embodiment system are described in detail below:

1) Protocol message network sniffing module: This system is connected to the network message mirroring port of the substation network switch. The type and signature word, real-time sniff the network packets sent to the mirror port of the switch. If the substation uses the IEC61850 protocol for communication, then start the 61850 network message sniffing module; if it uses the network IEC60870-5-103 protocol, IEC60870-5-104 protocol for communication, then start the message sniffing module of the network 103 or 104, according to the The communication protocol configures the sniffing module corresponding to the protocol, filters out the original target message that needs to be pushed, and adds it to the system original message buffer.

2) Push information processing module: The push information processing module regularly queries the original message buffer, and takes out the substation communication protocol message from the original message buffer, according to the message type and message protocol feature words, such as event type and device address , IED name, data set and other key fields to filter and classify information, process and convert it into the target format message to be pushed and add it to the corresponding push queue.

3) Information push module: According to the information subscription lists customized by different clients, multi-threading technology is used to read push information from relevant push queues, push to all clients who subscribe to the information, and update push records.

In order to facilitate the storage and query of historical push information, the system can also set up a historical push information database. For the information that has been pushed to all target clients, the system transfers the information to the historical push information database.

The system can also set a client connection detection and maintenance module to establish and maintain a long connection with the client. Through this module, the system periodically sends keepalive messages. If the link is detected to be interrupted, the original socket link is released, and Synchronously update the online connection client list.

As shown in Figure 3, the system can also set a push information customization and display module to realize the target push information customization and display. After the client is started, it will prompt the user to log in or actively try to connect to the server using the logged-in account. After the connection is successful, Modify and update the user-customized subscription information list and highlight the substation operation information pushed by the system when the user is not online.

The present invention is based on network message sniffing and active push technology of long-connection service information, and pushes relevant device information to corresponding clients in a real-time, accurate and targeted manner through the substation service system for the information concerned by manufacturers or relevant departments. It provides a means for manufacturers and operation and maintenance departments to keep abreast of the operating status of the device.
