Abstract:View of the current situation of serious water pollution, water quality monitoring means relatively backward status, a software of the multifunctional water quality monitoring based on LabVIEW was designed. The system used a network of communication, accessed to data from cloud networking platform and combined with MATLAB, Access database and Elman neural network technology. The system overview module, the data receiver module, water alarm module, data storage module, record sand query module and prediction module were designed. The function of data receiving, storage, query and forecast was accomplished. The results show that the system is stable and reliable, each function module can run normally, in a word, this software reaches the design standard and realizes the excepted functions.
