Design Of A Temperature And Humidity Control System Based On LabVIEW

Now most of temperature and humidity control system for incubator of infant is built based on intelligent instrument, which function blocks, such as parameter setting, parameter display, instrumentation and command system, and etc, are realized by hardware,. Using this method to build the system exists following disadvantage: interface is intermixture to lead to operation mistake, hardware is wear down to lead to system trouble, the qualities of the measurement and control characteristic are invisible. Moreover, actual incubator of infant does not control humidity independently.Consideration of the referring to problem above, and LabVIEW'S features that it is a state-of-the-art interface, function customization, interactive graphics, temperature and humidity control system for incubator of infant based on LabVIEW is designed here, which adopting 1-wire digital temperature sensor DS18B20 and humidity sensor HS1101 to realize the measurement of temperature and humidity, and adopting multi-sensor technology and data fusion algorithm to realize the fault early warming signal of sensors and data optimization, and designing two sets of...
