Open building automation and control network protocol conversion device and method

Abstract

The invention discloses a device and a method which are applicable to mutual conversion between building automation and control network internet protocol (BACnet IP) equipment and BACnet Ethernet network equipment. The device comprises an Ethernet network interface unit, a control unit and a working power supply, wherein the working power supply is connected with the network interface unit and the control unit respectively and provides working power for the network interface unit and the control unit; the control unit analyzes and re-encapsulates a BACnet IP message and a BACnet Ethernet message; and the network interface unit is connected with the control unit and is used for receiving message data transmitted by the control unit and forwarding the message data to the Ethernet network. The device is convenient to use, is low in energy consumption, and can be applied to network equipment which utilizes a BACnet Ethernet communication protocol as a main communication protocol to convert the protocol into a BACnet IP communication protocol; thus, greater application and development values are brought to BACnet Ethernet communication protocol equipment.

Description

technical field [0001] The invention relates to an open BACnet conversion device and a conversion method, which can be applied to network equipment with the BACnet Ethernet communication protocol as the main communication protocol, and converted into the BACnet IP communication protocol, thereby bringing more benefits to the BACnet Ethernet communication protocol equipment. Great application and development value. Background technique [0002] Since the first intelligent building appeared in the 1980s, intelligent buildings have developed rapidly in countries all over the world. After more than 20 years of practice and exploration, the functions of intelligent buildings have been continuously supplemented and improved, and the technology has been continuously updated and matured. With the development of modern information technology, the intelligent building system will continue to adopt the latest technology for system integration. The building automation network protocol...

Problems solved by technology

[0004] Although the byte message of the ISO8802 Ethernet protocol is short and the communication efficiency is high, the realization on the computer software requires a separate driver to support it, which brings great inconvenience to the application of BACnet Ethernet network equipment, that is, it must Use the supporting software of BACnet Ethernet network equipment, or master the more complex drive technology of Ethernet protocol

And even if the driver technology is mastered, because the software developed based on this driver technology must have this driver file when running, it also brings great restrictions on the reproducibility and applicability of the software.
