Description

[0001] INTELLIGENT MONITORING SYSTEM FOR WATER RESOURCE AND METHOD THEROF [0002]

The present invention relates to an environmental monitoring system for water resources management, and more particularly, to an environmental monitoring system for water resource management comprising a stand-alone power supply, a system control device, an airborne robot, a waterborne robot, .

As rivers become drinking water sources for citizens through the purification process, water pollution, environment and ecology should be managed at all times. Rivers are frequently contaminated by food waste, chemicals, and high temperature drainage from surrounding facilities, which may cause discomfort to citizens and may harm citizens' health by pollutants . In addition, if the pollutants are subjected to a more complex purification process at the water purification plant, the cost of water purification increases, and if the purification is not completed, the health of citizens may be threatened. In other words, it inflicts tangible and intangible damage on citizens.

On the other hand, even in the case of rivers with abundant and beautiful ecosystems, the lack of publicity by the government authorities makes it impossible to utilize resources properly. Therefore, it is necessary to enhance self-esteem as citizens of cities that utilize resources, manage rivers as well as environment and ecology by providing continuous and consistent information on rivers. In order to provide such information, it is necessary to build a highly integrated and integrated service system to collect information on the environment and ecology of rivers, and to analyze and display collected information.

In recent years, changes in water and marine environments due to rapid changes in various environmental disasters and weather, and increased pollution of marine and water sources have been the biggest factors threatening the cleanliness of fishery resources and pollution of natural wetlands and migratory birds . Accordingly, real-time observation of the marine environment for continuously monitoring various environmental changes such as marine ecology is urgently required.

Conventional water resource management systems use monitoring and control systems that operate and manage flow meters, pressure gauges, water quality, and other observation equipment on a block-by-block basis. The surveillance control system senses the signals output from the flowmeter and the pressure gauge, and records and stores the measured data in the memory at a predetermined time interval. The stored data is transmitted through a leased line modem, Internet modem or CDMA communication network according to the data transmission request from the supervisory control station or other set conditions. Such a monitoring and control system is operated and managed by an AC power source. However, there is a disadvantage in that power consumption is large due to the characteristics of a system for collecting and transmitting data in real time. In addition, even when data is not collected or transmitted, power consumption is still inefficient in terms of economy. It is necessary to overcome the above disadvantages to minimize the power consumption and to construct an environmentally friendly monitoring and control system.
