Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The protocol conversion function in this embodiment connects the terminal equipment through the RS-485 serial port, collects the power information, status information, etc. of the terminal equipment and converts it into an IEC61850 protocol protocol and connects with the monitoring system through the Ethernet port; connects the monitoring system through the Ethernet port, It consists of remote control information such as power on and off, remote adjustment information such as analog parameters, and converts it into TCP Modbus protocol. Control terminal equipment through RS-485 serial port, such as figure 2 shown. Specific steps are as follows:

[0018] 1. Firstly, according to the user's needs and in accordance with the IEC61850 modeling standard, carry out IEC61850 modeling on the corresponding function points, and automatically fo...

Abstract

The invention relates to a configurable conversion method for an IEC61850 protocol and a TCPModbus protocol and belongs to the technical field of protocol conversion. The configurable conversion method includes that a configurable conversion scheme is introduced to conversion of the IEC61850 protocol and the TCPModbus protocol, corresponding function points are subjected to modeling according to the IEC61850 modeling standard, and a dot mark table corresponding to models is automatically formed; relation mapping tables of dot marks in the IEC61850 dot mark table and dot marks in the TCPModbus protocol are configured, and a protocol conversion task and a 61850 task are configured by respectively utilizing the relation mapping tables and model configuration files; communication of a monitoring system and terminal equipment is realized according to the configured files. If the protocols are changed, only device models and the corresponding relation mapping tables are needed to be modified, the 61850 task and the protocol conversion task are reconfigured, program modification is not needed, workload is greatly lowered, efficiency is improved, and risk brought by the program modification is avoided.

Description

technical field [0001] The invention relates to a configurable conversion method of the IEC61850 protocol and the TCPModbus protocol, and belongs to the technical field of protocol conversion. Background technique [0002] Communication technology is the key technology for the automatic operation of smart substations. The unification and compatibility of communication protocols is conducive to the realization of interchangeability and interoperability of equipment in the substation system. In the substation communication network system, the protocol converter is generally used to convert the communication protocol, and the serial interface such as RS232 / 485 is used for data communication with terminal equipment such as relay protection and measurement and control devices. The communication protocol standard specified by the user is sent to the monitoring system. With the improvement of substation intelligence level, the communication protocol converter used in the substatio...
