Development of host computer software for crop water status monitoring system based on wireless sensor networks

Host computer software for the WSN-CWSM system was developed based on the Microsoft Visual C++ 6.0 and National Instruments LabVIEW 8.6. The designed host computer software was composed of two modules, namely, background management software and data management software. The background management software consisted of four sub-modules: data base, data processing engine, user graphic interface and background component, while the data management software consisted of five sub-modules: parameter setting, data acquisition, data processing, control output and data management. In the host computer software with WSN-CWSM system, standard Internet interface was implemented, correction engine of sensor nodes and data fusion mechanism of sensed data were realized, and all man-machine interfaces were designed as a friendly graphical interface. It was demonstrated by experiments that the designed host computer software possessed many advantages, such as good stability, perfect functionality, convenient man-machine interface, etc., and it could effectively organize and manage all sorts of sensed data as well as system data. At present, the developed host computer software can meet application requirements of the WSN-CWSM system.
