摘　　要：目的将基于蓝牙技术的个人区域网与基于BACnet的小区内部局域网相连接,使家庭中的各种设备通过安全的无线链路连接到CPU上,进行个人控制与小区内部物业管理系统的信息交换.方法建构系统组网模型,采用精简的TCP/IP协议包,在BACnet协议栈与蓝牙协议栈之间建立一条无缝链路.研究其算法实现步骤、协议软件连接以及系统硬件构成.结果利用无线网关和外部网络连接构成的智能化家居网络,可提供集中和异地的数据通信,使信息在家庭内部和外部之间充分流通和共享,避免了传统网络在家庭中错综复杂的布线方式,解决了蓝牙技术不能远距离传输的问题.结论基于蓝牙技术的个人区域网使智能家居网络系统具有更加广泛的灵活性和可扩展性,适用于住宅小区网络系统应用.PAN based on Bluetooth technology can be connected with community's intranet based on BACnet protocol to make the equipment in our houses link to CPU through a safe wireless link and exchange the information between personal control and community managing system.Condensed TCP/IP protocol package is adopted to build a model of system combination network.This model could build a non-split link between the BACnet protocol and Bluetooth protocol.What has been investigated includes not only the approach of the arithmetics but also the link of the protocol software and the composing of the system's hardware.The intelligent home network utilizes the link between the wireless net gate and the outer network.It could offer concentrated and outer data communication that makes the data circulated and shared between the inner and outer part of the family.The virtue of this solution is that it avoids the complex method of laying wires in traditional network and it resolves the Bluetooth technology's shortcomings of being unable to be long-distantly transmitted.The authors therefore draw the conclusion that PAN based on Bluetooth technology makes the intelligent home network system more flexible and more expandable,and thus applicable to the community's intranet system.
