The principle of communication conversion involves the process of converting one communication protocol or interface to another communication protocol or interface, usually through equipment or middleware. This conversion can cover different physical media, data formats, protocol standards, etc. The following are several common communication conversion principles:
1. Protocol conversion
Protocol conversion is the process of converting one communication protocol to another. For example, converting RS-232 serial communication to TCP/IP network communication, or converting Modbus protocol to BACnet protocol. This conversion usually requires a specially designed device or software that can understand and process the data format and communication rules of different protocols.
Working principle:
Data parsing: Parse valid data from the original protocol.
Format conversion: Convert the data format from the source protocol to the format required by the target protocol.
Protocol semantic mapping: Map the instructions and commands of the source protocol to the equivalent instructions and commands of the target protocol.
Data encapsulation: Encapsulate the data into appropriate data packets or frames according to the requirements of the target protocol.
Communication process control: Perform communication process control according to the protocol requirements, such as confirmation, retransmission, etc.
2. Interface conversion
Interface conversion refers to the process of converting one physical or electrical interface to another. Common examples include:
Serial to Ethernet: Convert RS-232 or RS-485 serial ports to Ethernet interfaces through serial port servers to achieve remote access and control.
Analog signal to digital signal: Convert analog signals collected by sensors to digital signals for easy processing by computers or controllers.
Working principle:
Signal conversion: Convert electrical signals from the specific electrical specifications of the source interface to the electrical specifications of the target interface.
Level matching: Ensure that the signal level and amplitude meet the requirements of the target interface during the conversion process.
Communication protocol conversion: When necessary, convert the communication protocol to meet the data transmission requirements of the target interface.
3. Network layer conversion
Network layer conversion usually involves interconnecting data in different networks, such as forwarding data in a local area network (LAN) to devices on a wide area network (WAN) through a router.
Working principle:
Routing selection: Select the appropriate routing path and gateway based on the address of the target device or network.
Packet encapsulation: Encapsulate the data packet into a format suitable for transmission on the target network.
Routing protocol processing: Execute the routing protocol on the router or gateway device to ensure that the data can be forwarded and exchanged correctly through different networks.
4. Physical media conversion
Physical media conversion involves data transmission between different physical media (such as optical fiber, copper wire, wireless signal, etc.).
Working principle:
Media adaptation: Select the appropriate physical layer transmission technology according to the difference between the source and target media.
Signal modulation and demodulation: For analog signals, modulation and demodulation are performed to adapt to different transmission media.
Media converter: Use a media converter or bridge device to convert data from one physical medium to another, such as optical fiber to copper wire.
