The present invention relates to an automatic control system for a power-saving smart rotary vibration damper.

In more detail, the present invention is to enable operation and control of the vibration damper based on the amount of water flowing into the water treatment facility (water level), the amount of change in the output current of the water channel, the concentration of suspended matter, and the like.

The present invention also compares the water level before passing through the screen and the water level after passing through the screen so that the vibration damper can be operated and controlled according to the comparison result.

INDUSTRIAL APPLICABILITY The present invention is applicable to a waterway such as a drainage pumping station, a waterworks intake station, a waterway for a related use, a sewage treatment plant, or a dam.

In general, in waterways such as drainage pumping stations, water intake stations, waterways, sewage treatment plants, or dams, a dust eliminator is installed to filter floating matter (collectively referred to as dust, foreign matter, or household waste) with a screen. .

A drainage pump for pumping water is installed in a drainage treatment plant or water intake plant, and a flat iron comb-tooth screen is installed in the inflow channel to filter floating substances such as filth or garbage to prevent pump failure, Floating matter caught on the screen is removed by pulling it up using a scraper that moves up and down along the front of the screen.

Here, the scraper raises the floating object caught in front of the screen from the lower part of the screen, moves it to the lower part of the screen spaced apart from the screen, and repeats the operation of lifting the floating object by contacting it in close contact with the front of the screen. However, the rotary method is used in which the scraper moves along the front of the screen to remove floating matter and then moves to the lower part of the screen through the rear of the screen.

As a specific prior art for a vibration damper, there is Republic of Korea Registered Utility Model No. 20-0442471.

Although most of the dirt is located near the water surface, the above technique mechanically repeats the operation of lowering and raising the beam to an unnecessary depth, thereby reducing the efficiency of vibration suppression work and shortening the life of the machine, and the guide installed across the waterway It was devised to improve the problem that effective vibration isolation cannot be achieved when vibration isolation work is required only in some sections of the waterway section by mechanically moving the entire section of the waterway along the rail. By detecting the water level and lowering the beam to an appropriate position to lift the dirt, the efficiency of the vibration removal operation is maximized, unnecessary load is not applied to the vibration damper, and the point where the vibration removal operation is to be performed on the waterway is notified to the control unit in advance. It is set so that the vibration suppression work can be done only at the set point.

However, the above technology detects the water level with a water level sensor and lowers the beam to the appropriate position to lift the dirt so that efficient vibration removal work is possible. could not be

In addition, the Republic of Korea Patent No. 10-1074826 installs a foreign substance draining port that lifts up foreign substances caught in the gap between the screens in the rake, but inclined to push the foreign substances toward the front side of the screen at the part where the foreign substances come into contact with the foreign substance extraction port When a load is applied to the drive motor while the foreign material outlet contacts the foreign matter caught between the screens, the driving motor that drives the chain rotates forward and reverse in a predetermined section by the control unit A rotary damper for drainage channels is disclosed that allows foreign matter caught between screens to be pushed out in front of the screen while repeatedly in contact by repeating the process several times.

However, the above technology also did not become a technology capable of reducing power and extending the lifespan by efficient operation of the vibration damper according to the water level.

[First embodiment]

1 is a block diagram of an automatic control system for a power-saving smart rotary vibration damper according to a first embodiment of the present invention. 2 is a flow chart for controlling a vibration damper according to the first embodiment of the present invention.

As shown in FIG. 1, the power-saving smart rotary vibration damper automatic control system according to the first embodiment of the present invention includes a water level sensor 10 that detects the level (inflow amount) of fluid flowing in the water channel 1 in which the vibration damper is installed; , a water level value generating unit 20 that generates a water level value based on the detected value of the water level sensor 10, and receiving the water level value generated by the water level value generating unit 20 to operate and control the vibration damper 40 The controller 30 may be configured.

The water level sensor 10 may be used as long as it can continuously sense the level of the fluid in real time. For example, when the water level sensor 10 emits ultrasonic waves to the surface of the fluid flowing in the water channel 1, it may be an ultrasonic sensor that detects the water level by receiving ultrasonic waves reflected back from the water surface.

The water level sensor 10 may be installed in a plurality at predetermined intervals in the water channel 1 to detect the water level in a wider area.

Also, the water level sensor 10 may be replaced with a pressure sensor installed at the lower end of the water channel 1 . In this case, the level of the fluid flowing in the water channel 1 may be continuously detected based on the pressure value sensed by the pressure sensor.

The water level sensor 10 may be connected to the water level generating unit 20 . The water level sensor 10 may be provided on the same circuit board as the level value generator 20 or may be separated. Alternatively, the water level sensor 10 may be configured to be able to send and receive only a detection signal without being physically or directly connected to the water level generating unit 20 .

The control unit 30 is a configuration for controlling the operation of the vibration damper, and the distance data from the installation position of the water level sensor 10 to the inner bottom surface of the water channel 1 and distance data when the water channel 1 is at full water level, etc. It can be programmed to analyze the water level flowing in the water channel 1 while being stored and managed in the memory 90 .

When programmed in this way, it is possible to analyze how high the water level is from the total height of the water channel 1 by calculating the distance based on the signal reflected from the water surface after being emitted from the water level sensor 10 .

The control unit 30 also stores the intensity (strength) data of the signal emitted from the water level sensor 10 returning from the bottom of the water channel 1 and the intensity data when the water channel 1 is at full water level. It can be programmed to analyze the water level flowing in the conduit 1 while storing and managing at 90 .

If programmed in this way, it is possible to analyze how high the water level is from the total height of the waterway by calculating the intensity of the signal that is reflected from the water surface after being emitted from the water level sensor 10 .

The control unit 30 may also be programmed to analyze how high the water level is from the total height of the waterway only by the distance calculated based on the signal that is reflected from the water surface after being emitted from the water level sensor 10 and returned.

The controller programming described above is illustrative only, and not limited thereto.

The operation of controlling the operation of the vibration damper based on the level of the fluid flowing in the water channel 1 may be performed as shown in FIG. 2 .

First, when a fluid flows in the flow path 1 ( S10 ), ultrasonic waves are emitted from the water level sensor 10 to the water surface.

Next, when the water level sensor 10 detects a signal reflected back from the water surface, the detected signal is input to the water level value generating unit 20 and generated as a water level value (S20).

Next, after the water level value is input to the control unit 30 and processed, the vibration damper operation is controlled under the conditions set for each water level (S30).

As the conditions set for each water level in the above, for example, when the water level is 0.1 meter (10 centimeters) or less, that is, when there is almost no fluid flow (inflow amount) in the flow path 1, operation is stopped, Low Level Water, that is, the water channel Low speed operation when the water level is about 1/3 of the height, medium speed operation when the water level is about 1/2 the height of the middle level water, and high speed operation when the high level water is full (in case of heavy rain, etc.) operation can be classified.

However, it is not necessarily limited only to these conditions.

In addition, when the water level is above a certain level, an emergency alarm and an emergency message may be generated through the alarm unit 70 and the display unit 80 as a danger detection alarm stage.

Meanwhile, as shown in FIG. 3 as another embodiment of the first embodiment of the present invention, the water level sensor 10 may be configured.

As shown in FIG. 3 , the water level sensor according to another embodiment may be installed such that two of the water level sensor 10 and the water level sensor 15 are inclined at a predetermined angle to each other. The water level sensor 10 may be for emitting ultrasonic waves, and the water level sensor 15 may be for receiving reflected ultrasonic waves.

When the water level sensors 10 and 15 are installed in this way, the signal emitted from the water level sensor 10 does not collide with the floating object 5 that may be located on the water surface, but directly hits the water surface and is reflected, and then enters the water level sensor 15 Therefore, the water level can be accurately detected.

That is, as shown in FIG. 1, when the water level sensor 10 is installed and ultrasonic waves are emitted to the water surface, it receives a signal that collides with the floating object 5 that can be located on the surface of the water surface and returns a signal, and by processing this signal, the floating object 5 It is possible to prevent an error in analyzing the upper surface of the surface as the water level.

On the other hand, the float 5 may be included in the lower side of the fluid, protrude above the water surface or may be located adjacent to the water surface. will be.

Of course, when there are very many floating objects 5 located on the water surface, even if the water level sensors 10 and 15 are installed obliquely at a predetermined angle, there is a high probability that the signal path is disturbed, but compared to the configuration shown in FIG. It will be more efficient.

In addition, the above-described configuration is useful under the assumption that more floats 5 may be included at medium and high water levels than at the lowest or full water level described above. It is possible to avoid errors in the analysis.

[Second embodiment]

4 is a block diagram of an automatic control system for a power-saving smart rotary vibration damper according to a second embodiment of the present invention.

In FIG. 4 , the water level generating unit 20 , the control unit 30 , and the vibration damper 40 shown in FIG. 1 are omitted.

Referring to FIG. 4 , the water level sensor 10 and the water level sensor 16 are installed with the screen 19 interposed therebetween. The fluid flowing into the water channel 1 passes through the screen 19 . For example, contaminants that may obstruct the flow of the fluid may be caught on the screen 19 . Therefore, there may be a difference between the water level before passing through the screen 19 and the water level passing through the screen 19 .

Therefore, in the second embodiment, the control unit 30 stores the distance data from the installation positions of the water level sensors 10 and 16 to the inner bottom surface of the water channel 1 and the distance data when the water channel 1 is at full water level in the memory ( It can be programmed to analyze the water level flowing in the water channels 1 on both sides with the screen 19 interposed therebetween while being stored and managed in 90 .

The control unit 30 also stores and manages the intensity (strength) data of the signal emitted from the water level sensor 10 returning from the water surface and the intensity data when the water channel 1 is at full water level in the memory 90. It can be programmed to analyze the water level flowing in the water channels 1 on both sides with the screen 19 in between.

As a result of comparing the water level h1 before passing through the screen 19 and the water level h2 after passing through the screen 19, if there is little difference, the vibration damper is operating normally and the screen 19 is It is judged that there is no contaminant enough to obstruct the flow of the fluid.

In this case, the control unit 30 may determine that the vibration damper is operating normally.

On the other hand, when the water level h2 after passing through the screen 19 is lower than the water level h1 before passing through the screen 19, it can be determined that the vibration damper is not operating normally, and at the same time, the screen It is judged that contaminants enough to obstruct the flow of fluid are hung in (19).

In this case, the control unit 30 may control the alarm unit 70 and the display unit 80 to generate an emergency alarm and an emergency message.

[Third embodiment]

5 is a block diagram of an automatic control system for a power-saving smart rotary vibration damper according to a third embodiment of the present invention. 6 is a control flow diagram of a vibration damper according to a third embodiment of the present invention.

The third embodiment of the present invention is to control the operation of the vibration damper according to the output current value of the water channel (1).

As shown in FIG. 5, in the third embodiment, the output current Ie is generated by a circuit composed of an input resistance Ri, an output resistance Re, and a transistor, and the control unit 30 controls the reference current and the output current. By comparison, the vibration damper operation is controlled according to the comparison result.

The operation of controlling the operation of the vibration damper according to the output current value of the water channel 1 may be performed as shown in FIG. 6 .

First, when the fluid flows in the flow path 1, an output current is generated (S10).

Next, the output current is sensed by the sensing unit (S20).

Next, the sensed output current is input to the control unit 30 and processed, and then the vibration damper operation is controlled under conditions set for each output current (S30).

As the conditions set for each output current in the above, for example, low-speed operation when Ie < N.C., high-speed operation when Ie > N.C., and economy operation when Ie ± 5% = N.C. Can be set.

Here, Ie is the observed output current, and N.C. is the normal current.

However, it is not limited to these conditions only.

Meanwhile, the third embodiment may be implemented in combination with the first embodiment.

Ultrasound is emitted from the water level sensor 10 to the water surface, and when the water level sensor 10 detects a signal that is reflected and returned from the water surface, this detection signal is input to the water level value generator 20 and is generated as a water level value. , after the water level value is input to the control unit 30 and the operation of controlling the operation of the vibration damper under the conditions set for each water level is performed according to the processed result, when an output current is generated due to the flow of the fluid in the flow path 1, this output A current is input to the control unit and compared with a reference current, and an operation of controlling operation of the vibration damper under conditions set for each output current according to the comparison result may be continuously performed.

In addition, such an operation may be performed by changing its precedence and back.

[Fourth embodiment]

7 is a block diagram of an automatic control system for a power-saving smart rotary vibration damper according to a fourth embodiment of the present invention. 8 is a flow chart for controlling a vibration damper according to a fourth embodiment of the present invention. 9 is an exemplary diagram illustrating the control division of a vibration damper according to a fourth embodiment of the present invention.

According to the fourth embodiment, filth having a higher specific gravity than water may be pushed toward the screen from the bottom of the waterway even if the speed is slow due to, for example, high water pressure and high fluid flow, and has a smaller specific gravity than water or a specific gravity with water Similar floats are implemented with the consideration that they can reach the screen quickly.

In addition, in the fourth embodiment, for example, considering that the lowest water level, low water level, or medium water level, it cannot be determined that the floating matter is less than the high water level or the full water level, and it cannot be determined that there are relatively many floating matters due to the high water level or the full water level. This was implemented so that the operation of the vibration damper could be controlled by combining the water level and concentration.

As shown in FIG. 1, the power-saving smart rotary vibration damper automatic control system according to the fourth embodiment of the present invention includes water level sensors 10 and 15 for detecting the level of fluid flowing in the water channel 1 in which the vibration damper is installed; A water level generating unit 20 for generating a water level value based on the detected values of the water level sensors 10 and 15, and a concentration sensor 50 and 55 for detecting the concentration of suspended matter flowing in the water channel 1 in which the vibration damper is installed ), a concentration value generating unit 60 that generates a concentration value based on the detection values of the concentration sensors 50 and 55, and the water level value generating unit 20 and the concentration value generating unit 60 It may be composed of a control unit 30 that receives the water level value and the concentration value and controls the operation of the vibration damper 40 .

The control unit 30 is programmed to set the distance that light travels according to the concentration, store and manage it in a memory, and control the operation of the vibration damper according to the combination signal of the water level and the concentration.

The water level sensor 10 may be configured for emitting an ultrasonic wave, the water level sensor 15 for receiving an ultrasonic wave, the concentration sensor 50 for emitting light, and the concentration sensor 55 for receiving light.

The fourth embodiment configured as described above is another embodiment of the first embodiment, that is, by adding the concentration sensors 50 and 55 in FIG. 3 , and sensing the level of the fluid flowing in the water channel 1 as in the first embodiment. In addition to removing contaminants, etc., it is possible to more effectively remove contaminants, etc. by sensing the concentration of floating matter flowing in the waterway and controlling the operation of the vibration damper.

The concentration sensor may be, for example, a photosensor. That is, the photosensor 50 that emits light and the photosensor 55 that receives the light reflected from the floating object are configured to calculate the distance that the light reaches from the entire height of the water channel 1, and use this as the water level sensor (10). It is to control the operation of the vibration damper by processing it in combination with the water level value detected in (15).

The concentration sensors 50 and 55 may also be installed to be inclined at a predetermined angle to each other like the water level sensors 10 and 15 so as not to obstruct the light propagation path due to floating objects that may be located on the water surface.

The concentration sensors 50 and 55 preferably use a light source emitting any one light selected from visible light, infrared light, ultraviolet light, and laser light.

When the concentration sensors 50 and 55 are installed in this way, the signal emitted from the concentration sensor 50 proceeds into the fluid and then is reflected and incident to the concentration sensor 55, and if a plurality of concentration sensors are installed, a wider It will be possible to effectively measure the concentration of the float for the channel of the area.

The operation of controlling the vibration damper based on the level and concentration of the fluid flowing in the water channel 1 may be performed as shown in FIG. 8 .

First, when the fluid flows in the flow path 1 (S10), the water level sensor 15 detects a signal that is reflected and returns a signal emitted from the water level sensor 10 to the water surface, and this detection signal is transmitted to the water level value generating unit ( 20) and generated as a water level value (S20).

In addition, the concentration sensor 55 detects a signal that is reflected back from the signal emitted from the concentration sensor 50 toward the fluid, and this detection signal is input to the concentration value generating unit 60 and is generated as a concentration value (S25). ).

Next, after these water level and concentration values are input to the control unit 30 and processed, the vibration damper operation is controlled under conditions set for each combination of water level and concentration ( S30 ).

As the conditions set for each water level and concentration in the above, for example, as shown in FIG. 9, when the water level is 0.1 meter or less and the concentration is the set value, the operation is stopped, the water level is 1/3 or less of the channel height, and the concentration is When the water level is lower than the set value, it operates at low speed, when the water level is less than 1/2 of the channel height and the concentration is higher than the set value, it operates at high speed, and when the water level is full and the concentration is lower than the set value, it can be controlled at medium speed.

However, it is not necessarily limited to only these.

On the other hand, as another embodiment of the fourth embodiment, for example, when the signals of the water level sensors 10 and 15 or the concentration sensors 50 and 55 are in error, that is, even though the fluid flows in the water channel 1 in real time In the absence of a signal, the vibration damper operation can be controlled based on any one signal.

That is, when the water level sensor 10, 15 fails, the vibration damper operation is controlled only with the concentration value detected by the concentration sensors 50 and 55, and when the concentration is low, it operates at low speed, and when the concentration is medium, it operates at medium speed. , if the concentration is high, it can be controlled by high-speed operation. However, it is not limited thereto.

In addition, as another embodiment, it may further be configured to control the operation of the vibration damper by processing the output current in combination, further in the process of combining the detection signals of the water level sensor and the concentration sensor.

In this case, the detection value of the water level sensor is the default, and any one of the detection value and the output current of the concentration sensor is selected and processed in combination with the detection value of the water level to control the operation of the vibration damper according to the processing result.

As described above, in the detailed description of the present invention, a preferred embodiment of the present invention has been described, but this is an exemplary description of the preferred embodiment of the present invention and does not limit the present invention. In addition, various modifications and imitations are possible without departing from the scope of the technical idea of the present invention by anyone with ordinary skill in the art to which the present invention pertains.

The vibration damper is divided into operation suspension, low-speed operation, medium-speed operation, and high-speed operation,
In the case of operation control based on the water level sensor detection value, if the detection value by the water level sensor judges that there is little flow of fluid in the waterway, the operation is stopped. When it is judged to be 1/2 of the height, it is operated at medium speed, and when it is judged to be full, it is controlled by high-speed operation.
When the operation is controlled in association with the detection value of the water level sensor and the detection value of the concentration sensor, operation is stopped when the water level is 0.1 meter or less and the concentration is the set value. Low-speed operation when low, high-speed operation when the water level is less than 1/2 of the waterway height and the concentration is higher than the set value, and medium-speed operation when the water level is full and the concentration is lower than the set value. Rotary vibration damper automatic control system.
delete The method according to claim 1,
The water level sensor is an ultrasonic sensor, and is configured to detect the height in the water channel of the fluid introduced into the water channel before and after passing through the screen.
