Hebei Province has a 487 km-long coastline and a developed coastal economy and is an important part of the coordinated development zone of Beijing, Tianjin and Hebei. However, Hebei Province is also one of the provinces most severely affected by various marine disasters, especially the storm surge disaster. The existing marine monitoring facilities are relatively far apart and cannot meet the current needs of disaster prevention and mitigation. In order to enhance the whole society's awareness of marine disaster prevention and to do a good job in prevention and mitigation of storm surge disaster, an intelligent alert tide level monitoring system which integrates real-time tidal monitoring and related meteorological information is designed on the basis of four-color warning tidal level value approved and released by Hebei Province. This system consists of support foundation, power supply module, meteorological and liquid level sensor, data acquisition and forwarding module and terminal management system. The intelligent monitoring sites built in coastal areas based on this system have the characteristics of low cost, small ground area occupied, fast construction speed and convenient for promoting. The establishment of such intelligent monitoring sites can efficiently enhance the capability of marine disaster warning and monitoring in Hebei Province and also provide important data support and decision-making basis for the warning, predicting, preventing and mitigating of marine disasters in Hebei Province.
