Abstract

The invention provides a protocol conversion method and device. The protocol conversion device at least comprises a first communication interface and a second communication interface. The protocol conversion method comprises the following steps: binding corresponding protocol types for the communication interfaces, and selecting corresponding decoding and encoding rules from a preset rule base; receiving source communication protocol data from a first communication interface, judging the protocol type of the source communication protocol data, and decoding the source communication protocol data to generate decoded data; and encoding the decoded data to generate target communication data, and sending out the target communication data through a second communication interface. The method and the device in the invention have the advantages that the types of source communication protocols and target communication protocols are unrestricted, thus realizing data conversion for a plurality of the existing standard protocols and manufacturer custom protocols, and solving the problems such as single product function and worse reusability as a result that only specific protocols can be converted in the prior art.

Description

technical field

[0001] The invention relates to the technical field of communication networks, in particular to a protocol conversion method and device. Background technique

[0002] In the existing communication field, there are many different network communication protocols. Taking the building equipment monitoring system, automatic fire alarm system, safety protection system, energy consumption collection and monitoring system configured in the intelligent building system as examples, due to the composition of the above The manufacturers, production time and application occasions of the various devices of several systems are different, and the communication protocols adopted are also very different. Some devices use Ethernet communication protocols such as Modbus / TCP, Ethernet / IP, BACnet / IP, etc., and some The equipment adopts PROFIBUS, DeviceNet, CANopen, BACnet / MSTP and other fieldbus communication protocols, and some of them adopt private protocols customized by manufa...
