Abstract
Virtual instrument(VI)is combines computer science,bus technology,software engeneering with measurement instrumentation techology,employes the computer's powerful digtal process compability to realize main function of instrument.It breakes the mainframe of traditonal instrument and forges a new instrument pattern.
Temperature control in daily life is one of the most common control behavior, it is widely applied to industrial production workshop, small to household room temperature control, will encounter problems. Temperature is an important parameter in the industrial production of industrial production, one plays an important role, for life, it is an important factor in the quality of life.Temperature testing is used extensively, and many kinds of detecting system. The system adopted in the hardware design STC89C52RC MCU and DS18B20 digital temperature sensors downstream machine hardware system with real-time temperature acquisition, enabling the temperature automatically record, analyze, and running, the system has good reliability, expansion, human design and performance of lower production costs. Using the Serial to SCM in the temperature data sent to the upstream machine (personal computer) for further processing and display in LabVIEW.
