摘要
介绍了 LonWorks 温度测量节点的设计。该设计选用数字温度传感器 DS18B20 作为温度传感器,8051 单片机为控制器,3510Neuron 芯片作通讯处理器,FTT-10A 为收发器,采用键盘显示器接口芯片 8279 完成键盘输入和显示功能,设置温度报警界限值;同时用 Neuron C 编写设计了 3150 接受数据的程序流程,用结构简单的单总线数字式温度传感器 DS18B20 与 LonWorks 温度测量节点的硬件设计,实现了低成本,高可靠性的温度测量。
Introduces the design of a LonWorks temperature measurement nodes. This design uses DS18B20 as the sensor , adopts 8051 one-chip computers as the controller, makes 3510 Neuron chip communication processor, applies FTT- 10A as transceiver and adopts keyboard display interface 8279 to finish keyboard in put and display function and set up the warning demarcation line value of temperature; at the same time, 3150 procedure of receiveing the data is written and designed with Neuron C. The combination of design of simple structure single digital temperature sensor DS18B20 of bus and the hardware of LonWorks temperature measurement node has realized the low cost and high dependability of temperature measurement.
