The detection method of the communication status of iec104 protocol in dispatching automation system

Abstract

The invention relates to a detection method for communication states of an IEC104 protocol of a dispatching automation system. The detection method comprises: (1). in the dispatching automation system, when the IEC104 protocol is used for communication, determining states of IP addresses of an opposite party, automatically selecting an IP address in a normal state to initiate establishment of a TCP / IP link; (2). determining whether a monitor service of a 2404 network port is started for each IP address in the normal state; (3) sending a testing frame message of the IEC104 protocol in each normal TCP / IP network link with a network port number being 2404, and determining, according to a response packet of the opposite party, whether each communication link of the IEC104 protocol is normal; and (4). storing the foregoing states in a database, and the dispatching automation system comprehensively determining, according to the states, an operation state of each IEC104 communication link. The present invention provides a unified and complete system platform for a user, so that the user can comprehensively learn various communication states of the IEC104 protocol on any node of the dispatching automation system, and the system platform is easy to maintain and convenient to operate.

Description

technical field [0001] The invention relates to a method for detecting the communication state of the IEC104 protocol of a dispatching automation system, which is used for a dispatching automation system using the IEC104 protocol communication, automatically judges the communication status of each IEC104 protocol, finds faults in time, and improves the reliability of system data collection, belonging to electric power Scheduling automation technology field. Background technique [0002] At present, it is more and more common to use the IEC104 protocol in the data collection of the dispatching automation system. The IEC104 protocol is a network communication protocol, which has the advantages of fast transmission speed and large data capacity. But what follows is that the data collection network of the dispatching automation system is getting bigger and bigger, and the network is also more and more nodes. The requirements for the network-related knowledge and communication pr...
