Design of LonWorks temperature measurement node

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.
