Abstract:The collection point and time of water sample is an important part of its representation in water quality monitoring and management, especially in the Yellow River basin into sewage outlet supervision work.In order to effectively solve the problem of inaccurate position and incomplete information during the water sampling, a system was designed to collect the real time information of water sampling through the technologies such as GPS precise positioning, QR code storage, FTP server transmission et.al.Through field testing, the results proved that the software could meet the design requirement and with adavantages of portable, accurate, fast, and efficient. The software was practical significant for achieving water quality sampling and remote control.
