摘要:
Nowadays, the intelligent building integration system includes different subsystems. Different subsystems use different communication protocols. Due to different types of intelligent devices in the same subsystem, the communication protocols used are also different, such as Modbus / TCP protocol, BACnet / IP protocol and various private protocols. Faced with the parsing of many kinds of communication protocols, if we write the parsing software for each protocol separately, the workload is large and the later maintenance is complex. Therefore, without the need to write a separate parsing program for each protocol, how to analyze multiple communication protocols is still an issue for intelligent building integration systems. Aiming at this problem, this paper combines database technology and protocol parsing technology, and uses the TCP protocol-based Socket technology to achieve mutual communication between networks. In this paper, a multi-protocol parsing and configuration system is proposed. A general-purpose protocol parsing component is designed to parse the received data packets according to the protocol data format configured in the database. © 2020 IEEE.
