Body temperature measurement has very important meaning in clinic diagnosis and treatment. Due to traditional artificial measurement style has mangy disadvantages such as long measurement time, and low measurement precision, etc, which is hard to automatically and accurately monitor patient body temperature in real time. Aiming to this problem, paper introduces a kind of body temperature distributed monitor system. Multi-temperature sensors DS18B20 were connected to realize body temperature signal collection, SCM AT89C52 processes measurement signal and drives field display and alarming equipment work. By nRF905 wireless transceiver chip, system completes signal wireless transmission from work slave station to work central station, and connects upper PC through USB adapter PDIUSBD12, which the distributed clinic patient body temperature concentration monitor system is carried out. Our experiments show that system wireless communication is better, and temperature measure error is less than plusmn0.1degC, which matches clinic medical requirement well. Due to system adopts modularization design, which can be transplant into other field, such as greenhouse environment intelligent monitor, etc.
