45、quot;1".As the simple structure, convenient installment, low loss and wide range of temperature test, DS18B20 temperature test sen sors are applied to the fields which n eeds the multipo int temperature test, such as the chemical industry, the grain, the environment supervision and so on. Becau

46、se of the adoption of one bus in the DS18B20 multipointtemperaturetest system, all DS18B20 are hung on one bus, and the n the temperature conversion value of each test point is read by turns. As the conversion value must be read after read in g-p in state for 8 times, and positi onandstore data must

47、 be moved, so time spe nd much in read ing one point of the data system by every time. If the temperature test system is large-scaled, the system loss caused by it is rather much, and then the alternate test speed of the system decreases obviously, which in flue nces the efficie ncy of the multipo i

48、nt temperature test system seriously .In this paper, DS18B20 are hung on some I/O buses by groupi ng DS18B20 eve nly, and the conversion temperature data is obtained by reading the state of DS18B20, the n the system loss decreases and the alternate test speed in creases obviously, which won ' t

49、in flue nee the precisi on and the reliability of the conversion.A set of multipoint temperature test of artificialen vir onment laboratory is achieved in this paper, which in creases the test efficie ncy of the former system.DS18B20 is the sin gle bus digital temperature sen sor from America n Dall
