摘　　要：本文介绍了一种基于LonWorks总线的智能安全防范报警节点的工作原理、硬件电路和软件实现。这种节点采用Host-Based结构,以MC68332 为主处理器,以神经元芯片3150为通信协处理器,具有烟火感探测、煤气泄漏探测和防盗报警的功能。它连接到LonWorks网络上,一旦发生盗情、火灾、煤气泄漏,能立即发出警笛声．同时将警情通过LonWorks总线传递到其它LonWorks节点和监控中心。To introduce a kind of safety annunciator based on LonWorks, including its functional pdnciple, hardware circuit and software design, This kind of annunciator is composed of two chips, the one is the neuron chip 3150 as the communication processor,and the other is the MC68332 as the host chip,which enhances greatly the control and process capability of the annunciator. The node not only has alarm function but also can communicate with supervisor or other instruments based on LonWorks.
