BACnet是专门针对楼字自动化并被广泛采用的有线通信技术.相对无线通信而言,BACnet存在安装不便、可扩展性差等缺点.简要介绍了目前热门的ZigBee无线通信技术,分析了无线技术在智能楼宇空调系统中应用的可能性；在此基础上,提出使用ZigBee无线通信技术,并重点设计了将无线ZigBee与BACnet有线通信互联的方案.实践表明,该方案能对现场温湿度信号进行采集与传输.最后,对无线技术发展前景作了展望.%BACnet is wired communication technology widely used in building automation system ( BAS) , but compared with the wireless communication technology, BACnet is inconvenient to install and hard to expand. The popular ZigBee wireless communication technology is introduced briefly, and the application possibility of wireless technology in smart building air-conditioning system is analyzed. Based on that, the application of ZigBee wireless communication technology is proposed, and the proposal of interconnecting the wireless ZigjBee wilh BACnet wired communication is designed emphatically. Practice shows that it can collect and transfer the field temperature and humidity signal. Finally, the development of wireless technology is prospected according to the actual situation.
