Description

Technical Field

[0001] The utility model relates to the technical field of electronic communications, and more particularly to a protocol conversion device. Background Art

[0002] Protocol converters, also known as communication management machines, enable data collection and forwarding, serving as a communication bridge between the plant and the master station. They enable data transmission from within the plant to dispatching systems at all levels or the group's unified monitoring and operation platform, seamlessly integrating with various brands of forward and reverse isolation devices and encryption devices. Protocol converters are primarily used in various automation network communication scenarios to convert communication protocols. Data is communicated with relay protection, fault recorders, electricity meters, DC panels, and other devices via serial interfaces such as RS232 / 422 / 485, as well as Ethernet interfaces. After program processing, data is sent to the monitoring backend or other application systems via the network or serial port according to the user-specified communication protocol standard. They are adaptable to harsh on-site operating conditions and can be widely used in distributed data collection and protocol conversion environments for various automation systems.
