Abstract
As the industry and the society developing, the temperature becomes more and
more important and a lot of products are sensitive to temperature. However,
temperaturemeasuring apparatus in the market now only can check and measure
the temperature of one point, at the same time, the temperature information is not
real time and the precision is low. It takes a great of troubles for the
industry-controllers to make decision .In this situation, design and implement
one applicable system which can watch measure and control the temperature and
the measuring results is real time and the precision is great is more essential. In
order to meeting this application, this paper talk about The Multiple-Point’s
temperature Measuring System.
This system based on single chip computer, can inspect and control multiple
temperatures in real time. As a kind of high-accuracy digital net temperature
sensor，DS18 B20 can be used building a sensor net easily. It can also make the
net simple and reliable with it's special 1-wire interface .This paper introduces the
application of DS18B20 with single chip processor.
