Aiming at the requirements of multi-points of temperature and humidity measurement and long time operation in the process of drug store,multiple microprocessors structure was used to design temperature and humidity monitoring system.The slave computer module of system included temperature and humidity sensors and micropower wireless transmitting modules,and the prob-lems of limitation for sensors placed and wire layout were solved; The personal computer was adopted as the host one,and the soft-ware was developed in the platform of LabVIEW.The host computer obtained data from all sensors through the serial port,and meanwhile it sent the control command to the control microprocessor to control the operation of air conditioner and humidifier;The remote clients visited the host computer via Ethernet to obtain all data and control states.By means of the reliability design of the system’s hardware and software,the reliability problem of uninterrupted work of the system was solved.The results of experiment show that the measurement accuracies of temperature and humidity of the system is 0.01℃ and 0. 05% RH separately,and the measurement points can be extended easily.
