The present invention relates to reservoir management, and more particularly, to a wireless integrated system for reservoir management.

Most of the reservoirs currently operating in Korea are managed depending on the five senses. The number of human physical resources we waste is beyond imagination. According to the Reservoir Management Enforcement Act, the building and public with a total floor area of 5,000 m ² or more under the provisions of Article 58 (1) of the Building Act are intended for reservoirs installed in the following buildings or facilities that use a large amount of tap water prescribed in Article 24 of the Water Act. Sanitation is more than the total floor area to use public facilities by 26 or more provisions of 3,000m ² office buildings, total floor area of 2,000m ² or more complex buildings, 1,000-seat theater auditorium, total floor area of 2,000m ² or more schools, wedding venue, more than 1,000 spectators In accordance with the provisions of Article 21 of the Water Act, and Article 6 of the Rules on Cleaning and Hygiene Management of Water Facilities, the manager or owner of a multi-family house or a large building must inspect the water tank sanitation more than once a month. In addition, water tank cleaning is to be carried out at least twice a year. Violation of this law will result in imprisonment of not more than two years or fines of not more than 5 million won under the provisions of Article 61 of the Water Act. However, the current situation is insignificantly following the demands of the administrative office on which this legal basis is based. In this situation, the need for an efficient system is gradually rising. Especially in the case of reservoirs operated in rural areas, the seriousness is increasing. If the human resources are gradually being reduced due to the avoidance of farming villages of young people, the management of the tank would be neglected if the responsibility for the management of the tank is passed on to the elderly people who remain in the rural areas. The first problem among the various problems caused by this is pollution of water resources. The Republic of Korea is currently a water shortage country defined by the United Nations. Until now, anyone has been using water easily without any problems, but now we must enter water management. Therefore, there is an urgent need for a system for efficiently managing the reservoir.

It is therefore an object of the present invention to provide a method for solving the above problems of the prior art.

A specific object of the present invention is to provide a system for reducing waste of human resources and managing the reservoir accurately and in real time.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the reservoir integrated wireless management system according to the present invention makes it easy to grasp the state of the reservoir in real time by managing the reservoir system and managing the reservoir in real time, and to respond quickly in case of an accident. In addition, it is possible to automatically detect the low water level and the full water level by the system, and the error rate is minimized because it is managed by a system other than humans, and it is possible to optimally manage the ratio of the water tank and the disinfectant, and to automatically control all the low water levels in the future. It is possible to develop.

In addition, the present invention provides the ease of securing a stable water resources. In other words, the reservoir is installed in farming and fishing villages that are not supported by a water supply system through a certain number of buildings or drainage in order to build a stable distribution system and solve drinking water problems in an emergency. Article 6 of the Rules on Cleaning and Hygiene Management of Water Facilities specifies that the reservoir should be cleaned once in June and the sanitary condition should be checked at least once a month according to separate standards. However, since the reservoirs located in the farming and fishing villages are integratedly managed by each town or village, it is impossible to periodically inspect the reservoirs. In this place, it is possible to check the current state of the reservoirs distributed in each area in one place and maintain the optimal state by establishing the integrated reservoir wireless integrated management system. You can respond flexibly. In addition, due to the climate of Korea, rainfall is concentrated during the rainy season, which may contribute to the drought that has been experienced in late spring or winter.

Finally, the present invention enables efficient human management. In other words, the way in which a person directly checks the state of a reservoir as in the past has been the idea of a backward country in terms of human resource management efficiency. What this system implements is a computer-based integrated management system that can reduce the waste of human resources, and through this, it is possible to organize the organisms of the upper and lower upper organs precisely. For example, a ward or city hall can manage all the reservoirs in a jurisdiction with just one computer monitor, making it easy to sit and handle what a person had to run. This will not only save a lot of human resources, but will also achieve higher efficiency than previous methods due to an accurate real-time management system.
