The first level sensor 300 is an apparatus for measuring the height of water stored in the fluid reservoir 10, and may be an ultrasonic sensor or a radar sensor.

3 is a transparent perspective view of the fluid reservoir in which the first level sensor is installed;

3, when the first level sensor 300 according to an embodiment of the present invention is a radar sensor, the operation principle will be described. The microwave pulse signal emitted from the first level sensor 300 is applied to the fluid surface The microwave pulse signal generates a microwave pulse signal reflected by the fluid surface due to the encounter of another medium (air → water) and receives the signal by the antenna. The microwave pulse signal reflected from the antenna installed on the tank is detected and the distance from the fluid surface is measured, and the expression "distance = velocity × time" is used.

The second water level sensor 400 includes a plurality of magnetic sensors for sensing the intensity of the magnetic force to sense a signal, and in particular, the magnetic sensor may be a hall sensor.

4 is a conceptual diagram for explaining the operation principle of the Hall sensor.

As shown in FIG. 4, the Hall sensor is connected to both the Hall element (n-type semiconductor) and the terminals of the Hall element for supplying current. When a magnetic field is vertically applied to a terminal for supplying a current, holes and electrons contained in the Hall element are separated at both ends to form a predetermined voltage, that is, a Hall voltage (V _H ). Current flows through the Hall voltage, and the hall sensor detects the amount of current flowing by the Hall voltage to sense the intensity of the applied magnetic field.

The second level sensor 400 according to an embodiment of the present invention includes a plurality of magnetic sensors. As shown in FIG. 2, the plurality of magnetic sensors are spaced apart from each other by a predetermined distance in the longitudinal direction of the sensor support member 420 And is fixedly installed. The second water level sensor 400 is fixed to the outer surface of the upper surface of the fluid reservoir 10 by the sensor supporting member 420 included in the second water level sensor 400 and the second water level sensor 400 is included The sensor support member 420 may have a length equal to the height of the fluid reservoir 10 and the second water level sensor 400 may sense the low water level, A second magnetic sensor 440, a second magnetic sensor 450 and a third magnetic sensor 460.

The magnet 810 to apply a magnetic field to the first magnetic sensor 440, the second magnetic sensor 450 and the third magnetic sensor 460 included in the second water level sensor 400 is a magnet supporting member 800, and one side of the magnet support member 800 is attached to the buoyant body 600 located on the surface of the fluid. In particular, the magnet support member 800 protrudes from the upper surface of the fluid reservoir 10 through the opening 820 formed in the upper surface of the fluid reservoir 10 and is freely movable in accordance with the height of the fluid surface in the fluid reservoir 10 Up and down movement becomes possible. The sensor supporting member 420 and the magnet supporting member 800 may be made of a metal material such as aluminum or a plastic material which is not corroded by the liquid.

The buoyant body 600 may be made of Styrofoam and is fixed to the upper and lower surfaces of the inside of the fluid reservoir 10 and fixed by a buoyant body support member 700 that induces up and down movement of the buoyant body 10 .

As a result, the height of the fluid carried in the fluid reservoir 10 increases according to the amount of fluid flowing through the inlet 100 of the fluid reservoir 10, and the buoyant body 600 also rises along the surface of the fluid. When the buoyant body 600 rises, the magnet support member 800 also ascends, and the magnet 810 formed on the upper side of the magnet support member 800 is separated from the first magnetic sensor 440 included in the second water level sensor 400 And applies a magnetic field signal to the second magnetic sensor 450 or the third magnetic sensor 460.

When the fluid flows through the inlet port at a predetermined height, the magnetic field formed at the lower portion of the plotter 112 does not apply a magnetic field to the inlet sensor 110 and no signal is input to the inlet sensor 110. If the fluid does not flow into the inlet port 100, the magnetic substance 116 formed at the lower portion of the plotter 112 applies a magnetic field signal to the inlet sensor 110 so that the inlet port 100 It is possible to judge that no fluid is flowing into the fluid passage.

The inlet blocking device 120 may be provided in the inlet 100 and may be physically located in the inlet 100 if the fluid is no longer flowing, And functions to block the inlet 100 so that the fluid does not enter the fluid reservoir 10. The inlet port blocking device 120 may be rotated and fixed at a predetermined angle by the opening and closing means 122 attached to the outside of the inlet port 100 in the same shape as the inner end surface of the inlet port 100 to block the inlet port 100 .

The fluid storage control device 900 receives a signal sensed from the first water level sensor 300 and the second water level sensor 400 to generate a radio signal for controlling the water intake motor and outputs a signal from the intake sensor 110 And controls the inlet port blocking device 120. Further, when a failure of the first level sensor 300, the second level sensor 400, or the inlet sensor 110 is detected, an alarm signal is sent to the alarm device.

The transmitting device 920 transmits signals generated from the fluid storage control device 900 to an external device via the wireless network. Generally, signals for controlling the intake motor control device are transmitted.

The components of the fluid reservoir according to one embodiment of the present invention have been described above.

When the fluid flows, the fluid level in the fluid reservoir 10 rises, and the first water level sensor 300 senses the water level through ultrasonic waves, microwaves, and the like. The second water level sensor 400 also ascends the float body 600 together with the fluid level and rises along with the magnet support member 800 attached to the buoyant body 600 and the magnet support member 800 A magnetic field is applied to the second magnetic sensor 450 and the third magnetic sensor 460 by a continuous rise after a magnetic field is applied to the first magnetic sensor 440, A hole voltage is formed by a magnetic field applied to the sensor to make a current flow, and the presence or absence of a current or the intensity of a current is detected to determine the fluid level in the fluid reservoir 10.

However, as described above, when the ultrasonic sensor or the radar sensor used as the first level sensor 300 malfunctions or fails, a signal that can stop the operation of the water intake motor is not transmitted, and the water level in the fluid reservoir 10 Continues to rise and floods through the cover of the fluid reservoir shown in FIG. Fluid overflowing the fluid reservoir (10) can cause rice or other fields to flood and cause further damage. However, if the first level sensor 300 malfunctions or fails, the fluid reservoir 10 according to the present invention senses the full water level and transmits a signal to the fluid reservoir control device 900, The control device 900 transmits a signal for controlling the intake motor via the transmission device 920. [

Further, if a state in which the control of the intake motor is impossible due to the remote reception failure or the failure of the reception device occurs despite the transmission of the signal for controlling the intake motor of the fluid storage control apparatus 900, The plotter 112 continues to rise, and the inlet sensor 110 can not sense the signal by the magnetic body 116.

The fluid reservoir control device 900 includes a timer (not shown) so that when the fluid continues to flow through the inlet 100 within a predetermined time period despite the transmission of a signal to stop the intake motor 110) to operate the inlet shut-off device 120 to mechanically shut off the inlet 100.
