摘要： A wireless telemonitoring system was designed aimed at the agro-enviromental data acquisition accounting for the agricultural characteristics of remote sites such as distance from developed communities, multiple environmental factors, mutable conditions disturbed by natural disasters, and so forth. An environmental data acquisition system, WITSYMOR V1.0, was developed, which could be connected with most of common sensors, for measuring temperature and relative humidity, soil moisture, CO(2), air pressure, PAR, total solar radiation, soil pH and EC, etc. The kernel techniques of the system were to realize a seamless connection between a wireless mobile network (GPRS/CDMA) and the Internet using TCP/IP software programming to relay the data from the former to the latter. The data were acquired in real time and transmitted to the central database servers from the remote agricultural sites, where they could be browsed, applied and downloaded by authorized users at anytime and anywhere. At present, it has been set up in some agricultural stations, horticultural greenhouses, methane-gas pools, as well as in animal shelters. The results show that the system is stable, and it is very adaptive to monitoring various agricultural environmental factors in remote sites.
