ABSTRACT
This paper presents a kind of message conversion method between wired/wireless hybrid network, aiming at meeting the encapsulation and transmission application requirements of Building Automation and Control network (BACnet) protocol messages in ZigBee network. It also proposes a kind of compatible frame structure and addressing method which is specific to wired/wireless network hybrid transmission. It discusses a design of BACnet/ZigBee wireless temperature sensor node from the point of software and hardware, and completes node software and hardware design of BACnet/ZigBee wireless temperature sensor by the embedded system Lm3s6911+, and bidirectional parsing, encapsulating, addressing, sending and receiving process between ZigBee messages and BACnet Ethernet messages are realized. This solution also can extend the current transmission and application range of BACnet messages, and provide an effective way to wired/wireless network hybrid transmission of building automation data.
