In general, domestic sewage or factory wastewater contains a lot of substances such as phosphorus and nitrogen, and in the water of rivers and seas into which such domestic sewage or factory wastewater flows, nutrients such as phosphates and nitrates increase, leading to eutrophication. do. When such eutrophication occurs, the plankton that feeds on it suddenly increases, causing algal blooms, and the amount of dissolved oxygen decreases, which causes the death of aquatic organisms.

As a method to prevent water from rotting due to the propagation of plankton as described above, in order to increase the amount of dissolved oxygen in the water and to forcibly convect deep water with a relatively low temperature into the surface water to lower the temperature of the surface water, dams or water sources An aeration device is installed in the ground, and this aeration device increases oxygen in the water by blowing air into the water, and at the same time turns the water in the deep water to prevent the water quality from dropping.

As such conventional devices, a relatively large water wheel method and a centralized large-capacity fixed aeration device are operated. Recently, a miniaturized water wheel type aeration device has been used.

Republic of Korea Patent Publication No. 10-2006-0005136 is a representative example. It is fixedly installed in the aeration tank to supply oxygen but to generate a vortex to improve the oxygen dissolution rate. Since the device is fixedly installed inside the aeration tank, if its maintenance is required, it is possible to drain the water inside the aeration tank and then rain, which causes considerable inconvenience in maintenance.

In addition, the existing aeration apparatus has disadvantages in that it is not possible to determine the contamination level of the water by a manual operation method, and it is impossible to manage dissolved oxygen according to the amount of water inflow.

10 is a block diagram of a remotely operated aeration system according to an embodiment of the present invention.

Referring to FIG. 10, the remote operation aeration apparatus and the system of the present invention include a GPS satellite 1, a sensor unit 2, a server 4, a smart controller 5, a manager terminal 3, and an aeration device ( 6) may be included.

First, the GPS satellite 1 may determine the real-time location of the aeration device 6 and transmit a location signal to the server 4 .

In addition, it includes one or more of a flow measurement sensor, a turbidity sensor, a temperature sensor, an oxygen measurement sensor, and the like, but is not limited thereto.

The flow measurement sensor is a sensor that measures the flow rate flowing into the water. In order to secure the amount of dissolved oxygen required according to the level of pollution in the water, it detects the flow rate flowing into the water. The rotation speed of the impeller 66 can be controlled.

The turbidity sensor is a sensor that measures the degree of turbidity of water, and it can be determined that the more cloudy the turbidity, the more severe the water pollution.

The sources of turbidity are divided into inflow factors of organic and inorganic substances due to natural and man-made causes. Examples of natural factors include floods, microorganisms grown in water, erosion of rocks, etc., and artificial factors include domestic sewage, industrial wastewater, landfill leachate, etc. There is this.

The temperature sensor is a sensor for measuring the temperature of water, and since the amount of dissolved oxygen decreases when the temperature of the water increases, it is possible to determine the degree of pollution in the water.

The oxygen measuring sensor is a sensor that measures the amount of dissolved oxygen, and it can be determined that the lower the amount of dissolved oxygen, the more severe the water pollution. Since fish and shellfish or aerobic microorganisms breathe through oxygen dissolved in water, when the amount of dissolved oxygen is low, fish and shellfish die, and aerobic microorganisms stop proliferation or growth activity.

Also, plants use dissolved oxygen mainly for root respiration, and when dissolved oxygen is low, growth is slowed or stopped. Accordingly, as the amount of dissolved oxygen decreases when there is more organic matter in water, dissolved oxygen can measure the degree of contamination in water.

At this time, the water quality information collected by the sensor unit 2 is transmitted to the server 4 and can be divided into judgment information through the server 4, and the judgment information is poor water quality, normal water quality, depending on the degree of water pollution. and good water quality information.

In addition, when movement information is input to the manager terminal 3 , the manager terminal 3 may transmit it to the smart controller 5 through the server 4 to cause the aeration device 6 to move.

The server 4 may transmit the control information to the smart controller 5 by receiving the location information from the GPS satellite 1, receiving the water quality information from the sensor unit 2, and generating control information.

In addition, the server 4 generates determination information based on the location information received from the GPS satellite 1 and the water quality information received from the sensor unit 2 , and transmits it to the manager terminal 3 , the manager terminal 3 . to input operational information.

In addition, the server 4 may receive the operation information from the manager terminal 3 and transmit it to the smart controller 5 .

The smart controller 5 receives control information and operation information from the server 4 to control the motor of the aeration device 6 , and by controlling the rotation speed of the motor 62 , the air in the aeration device 6 is The inflow can be adjusted.

Accordingly, the aeration device 6 can be automatically operated through the server 4 and the smart controller 5 based on the location information received from the GPS satellite 1 and the water quality information collected from the sensor unit 2 , , it is possible to remotely operate the operation information input from the manager terminal 3 through the server 4 and the smart controller 5, so that water quality can be improved.
