Solar Wireless Intelligent Online Hydrological Monitoring System

Water environment monitor is an important component of environmental monitoring system. In this paper, the authors discuss that the solar energy technology, the wireless GPRS network transmission technology, VPN agent technology, sensor technology and information security technology could be employed in the field of hydrology intelligent on-line monitoring to solve the on-site monitoring of power supply, and expanded the scope of monitoring and capacity. Through the VPN Proxy Server to provide guidance for on-site data collection and achieve "the collection, processing, and application" integrated treatment, and then to meet the needs of the systematic monitoring of ecological environment, geology, soils and climate. This system uses an embedded Linux system deployment, and security certification technology.
