Problems solved by technology

This kind of processing method seems simple and clear, but it has the disadvantages of low efficiency, low real-time performance, and the inability to realize concurrent processing of receiving and sending. Therefore, a more efficient and concurrent processing method is urgently needed.

Embodiment 2

[0035] Embodiment two, message error processing, for the message that corresponding error code has been defined on MMS agreement, program adopts and obtains corresponding return error, adopts the mode of processing in different ways according to error;

[0036] Errors mainly include some basic errors when establishing a connection with the server. There are two steps to deal with. First, there is a PING program in the program. If the PING works, it means that the network is normal, otherwise the network is not normal. Second, process it in the function of parsing the message. If it is an error message, discard the frame. If the parsing is not completed, flush the frame. Third, according to the result of PING, if the PING is successful, it will be disconnected. Open the connection, and then re-establish the connection. If the PING fails, it will call the police and inform the user that the network may be interrupted, but the program still connects to the server regularly, and th...

Abstract

The invention discloses an IEC61850 design method based on electric power monitoring. It is based on the messages sent by various MMS message servers, correctly encodes and decodes the MMS protocol, and then encodes and decodes the MMS messages. The whole system The design process includes the following steps: a. Process of parsing messages; b. MMS software design; c. Message response process; d. The entire IEC61850 dynamic library data stream communication scheme, which is an asynchronous communication method, analyzes and processes messages and Sending the message and responding at the same time, after receiving the server message, respond to the message, analyze all kinds of messages when parsing the message, get the analysis result, and finally store the obtained structure. The present invention extracts data while checking, and its storage method adopts a storage method in which dynamic storage space, agreed data type, server data and redundant data backup are stored at the same time, an efficient and safe message error processing scheme, and further improves the safety and security of the system reliability.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a design method for developing IEC61850 for power monitoring. technical background [0002] The currently widely used power monitoring IEC61850 based on the power communication MMS protocol has many defects in its design structure and processing process. A commonly used method is to use a synchronous method, sending and receiving share a thread, first check whether there is a command to send, and take a command from the sending queue, map it to the MMS command, send it to the command receiver, and then enter the waiting command In the process of the receiver's reply, the command is processed after receiving the reply, and then checks whether there is a command to be sent, and enters a cycle of sending and receiving. This processing method seems simple and clear, but it has the disadvantages of low efficiency, low real-time performance, and the inability to realize concurrent process...
