Description
Technical Field
The invention relates to an IEC103 message analysis method and device based on a multistage classification mode, and belongs to the technical field of power system data transmission.
Background
An IEC103 protocol based on an RS485 communication mode is usually adopted in a 500kV conventional transformer substation interval layer network, and in the process of daily maintenance, maintenance personnel often pay attention to the external problems of the device and ignore the interpretation of network messages in the substation, but the interpretation of the messages is an important means for effectively improving the working efficiency. The message formats displayed by the existing message analysis tools are all original 16-system formats, message information is not sorted, and the readability is poor, which is also a main reason for restricting the maintainers from actively analyzing the messages.
The existing inspection mode has the following problems:
1. readability is poor. The conventional message analysis tool does not analyze or translate the message, only displays the message by the most original 16-system number, and displays a large number of unaligned numbers, so that field maintainers have trouble looking up and key data are easy to miss;
2. the field applicability is not strong, no message classification is carried out, and no reading is carried out on key messages. For field service, there are two general problems,
problem 1 is that the communication of the AB network of the protection device is abnormal or interrupted, and the fault is mainly caused by the communication system between the protection device and the management machine being damaged, so that the fault point is determined to be on the protection side, the communication line or the protection management machine. The existing analysis tool does not carry out message combing, especially when multiple protection devices are in cascade communication, a large number of heartbeat messages and general calling messages can be generated, and a maintainer cannot quickly find a message of a fault device or an access message issued by a main station in the presence of a large number of original messages, so that the maintainer uses less message analysis tools, but message reading is an important means for effectively improving the working efficiency.
Problem 2 is that the master station remote control is unsuccessful. Due to many factors of unsuccessful remote control, for example, it is possible that the command is not successfully issued to the master station, the protection device does not send a remote control confirmation message, and the like. The existing message analysis tool does not highlight the key points, and when a large number of messages are analyzed, the key points of the remote control messages are not highlighted, so that a maintainer cannot quickly look up related information to analyze faults.
The IEC103 message analysis method and device based on the multi-level classification mode are provided, the analyzed result is translated in a Chinese form, the multi-level classification method is used for message analysis, analysis key point analysis is carried out on the remote control message, and the method and device have the advantages of being high in readability, simple to operate and convenient to carry.
