Abstract: Remote on-line monitoring on water withdrawal is a basic work for fine water resources management. In line with the requirements of water resources management, a remote online monitoring system for water withdrawal based on the internet of things is constructed and analyzed. The system is composed of three levels the layer of equipment perception, the layer of network and the layer of application. The system has major functions including user management, data acquisition, data processing, and network service, etc. Key technologies and complex problems in the design and implementation are illustrated and discussed. The framework, functions, data organization and application result of the system are introduced. The system is stable and reliable, and provides real time, true and reliable water withdrawal data for water resource management.

Key words: the internet of things, remote online monitoring on water withdrawal, WebGIS
