Due to numerous communication protocols and incompatibility with each other, power equipment or monitoring systems cannot be directly interconnected with each other. Protocol converter is the key technology to realize the interconnection of different devices or systems. IEC61850 protocol converter is a device to realize protocol conversion.

        The protocol converter usually realizes the conversion of communication interface and communication protocol. The protocol converter should be connected with different devices, and the communication interface should match them. 61850 protocol converter requires a network port to connect with the monitoring computer, an RS485 or RS232 and other communication interfaces to connect with the intelligent equipment. If you want to connect more devices, the protocol converter needs to configure more interfaces.

        The protocol converter is like a transportation hub. The data of different devices need to be collected into the protocol converter and then transmitted to other devices through the protocol converter. Therefore, the key of system design is to understand the communication protocols of various devices, and realize the mutual conversion algorithm between different protocols on this basis.

        61850 protocol converter is generally used as an embedded device, and users rarely operate it. Therefore, generally only a simple man-machine interface is designed, that is, the status indicator, which tells the user the operation status of the equipment through different indicators.
