Abstract:At present, highspeed developing internet of things (IOT) and cloud computing technology provide revolutionary upgrades for industry, farming and living. In the groundwater monitoring system designed in this assay, industrial communication technology can be used to automatically collect data from sensors and form dataset under OPC regulation. The dataset would be quoted and recorded by configuration software deployed at cloud server. The goal of collecting and recording the groundwater monitoring data can be realized. This system can optimize and upgrade the data collecting and transporting technologies, dramatically increases the amount of monitor points that a single server can deal with. So the system has the ability to perform dynamic monitoring for enormous targets to meet the need for groundwater environmental information.
