Fluid drain pump control system using IoT

The present invention relates to a fluid drainage pump control apparatus using the Internet of Things, and more particularly, to detect a state in which a fluid flowing into a water tank, a water supply tank, a sewage tank, and the like reaches a predetermined level without leakage current and uses an IoT. It automatically notifies the designated management means at the remote site, and monitors the operation status of the drainage device including the water level detection sensor and the drain motor under the control of the remote management means, and operates without standby power consumption by controlling the remote site connected to the IoT. The present invention relates to a fluid drainage pump control apparatus using the Internet of Things, in which water level adjustment is precisely and automatically controlled.

Fluid, such as water, is a material that transfers electricity well because of its relatively good electrical conductivity.As a fluid is an amorphous material, a container such as a container or a container is required for storage, and a container means for storing or storing in a large quantity is a water tank, a collection tank, a water supply tank. Etc.

The water supply and drainage control device for introducing or discharging fluid into a reservoir, a collection tank, a water supply tank, etc. is composed of an electric circuit, and when a leakage current flows from the electric circuit and flows into the fluid, there is a risk of safety accident due to an electric shock of the worker or user. Various sensors for monitoring the water level, pumps for moving fluids, and electronic circuits including control circuits may malfunction due to leakage currents.

There is a detection method that measures (levels) the level of the fluid flowing into the reservoir, the sump, or the water supply tank, so that electricity flows through the fluid, and the level is measured when the leaked electrical signal is detected through the detection terminal. .

Conventional technology that partially solves the necessity of adjusting the level of the fluid, according to the Republic of Korea Patent Registration No. 10-0459385 (2004.11.22.), There is a "water tank level control device".

On the other hand, the fluid level detection method according to the prior art has a relatively simple circuit configuration for measuring the water level, is inexpensive, and is relatively used due to the stability of the operation. Since there is a possibility of an accident, it is necessary to monitor the leakage current and control the leakage to not exceed the allowable amount.

Generally, a plurality of water level detection sensors, a drainage pump for discharging fluid, a control circuit for analyzing the water level and controlling the operation of the pump, a lamp, an air conditioning unit, etc., in order to maintain a constant level of the water tank, the sump tank, and the water supply tank These various devices or facilities require the supply of operating power, and use an outlet such as a power strip to supply the operating power to each device.

Hereinafter, a device for storing and discharging fluid at a constant level, such as a reservoir, a sump, and a water tank, will be described as a 'storage tank'.

The water level detection sensor, drain pump, control circuit, and heating and cooling device connected to the outlet require supply of standby power for rapid operation when a control signal is applied, and operate quickly in an emergency by supplying standby power. Although there is an advantage in that the power can be unnecessary or wasted in normal times.

As a conventional technique that solves some of the problems of the conventional method, the Korean Patent Registration No. 10-1205712 (2012. 11. 22.) includes a "self-standby power cut-off outlet and its own standby power cut-off method."

1 is a functional configuration diagram of an apparatus for detecting a water level detection of a reservoir as a leakage current according to an embodiment of the prior art, and FIG. 2 is an apparatus for shutting off standby power of an outlet according to an embodiment of the prior art. It is a functional block diagram explaining.

According to FIG. 1, since the water pipe 25 operates the water pipe valve 33 according to a control signal of the water level sensing circuit, water is supplied to or stopped in the water tank 13, and the water level is detected inside the water tank 13. In order to do this, the water level detection sensor 31 including the first to fifth electrodes E1 to E5 is installed. The first to fifth electrodes E1 to E5 constituting the water level sensor 31 flow a leakage current into the reservoir 13 by the water level detection circuit.

The capacity of the fluid (water) flowing into the reservoir 13 is measured according to which of the first to fifth electrodes E1 to E5 detects the leakage current flowing through the water level sensor 31. Is analyzed by the water level detection circuit to control the water pipe valve 33 in the on (ON) or off (OFF) state.

However, the prior art as described above has a problem that the leakage current flowing into the reservoir 13 through the water level sensor 31 may threaten the safety of the person or worker using the reservoir.

2, an outlet including an AC input unit 110, an AC output unit 160, a relay switch 140, a control unit 150, an AC / DC conversion unit 120, and a micro switch 130. Safety is ensured by cutting off standby power.

For example, the AC input unit 110 of the outlet inputs commercial power and supplies it to the AC output unit 160 via the relay switch 140, and the relay switch 140 operates by a control signal of the controller 150. The controller 150 operates when the operating power is supplied from the AC / DC converter 120, and the AC / DC converter 120 operates when a signal of the micro switch 130 is input.

In addition, the micro switch 130 is a physical switch installed in the insertion hole of the outlet, is installed on the side wall of the insertion hole to detect whether the plug is inserted, and when the plug is inserted to the operation signal to the AC / DC converter 120 Output configuration.

However, since the outlet according to FIG. 2 is configured to physically detect an inserted state of the plug to continue or cut off the supply of standby power, there is a problem in that standby power of a device that is always physically connected to the outlet cannot be blocked.

Therefore, there is a need to develop a technique for monitoring leakage current and blocking standby power from unnecessary waste in detecting and adjusting the water level in the reservoir.

However, this is not intended to limit the present invention to specific embodiments, it should be understood to include all transformations, equivalents, and substitutes included in the spirit and scope of the present invention. In the following description of the present invention, if it is determined that the detailed description of the related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

In the following description, detection and measurement will be used in the same sense, and will be described as appropriate in the context.

According to Article 27 (Electrical Wire and Insulation Performance of Electric Cable Line) of Article 27 of the Electrical Equipment Technical Standard, which is set by the Korea Electric Association, The insulation resistance should not exceed the leakage current of the supply voltage to 1/2000 of the maximum supply current 'has been proposed a standard of leakage current value that should be managed at all times. Let's apply.

3 to 5, the present invention includes an outlet part 1000, a water level detection part 2000, a drain pump part 3000, a reservoir 4000, and a reservoir management headquarter 5000.

At this time, the outlet unit 1000 is input to the commercial power (AC), while monitoring the leakage current flowing through the connected equipment to cut off the standby power and is connected to the IoT by the wireless LAN.

In particular, the outlet part 1000 may be similar to a general power strip, and a plug insertion part into which a plug provided in each device is inserted is formed, and the plug insertion part is not shown in the drawing. Here, the load may be described as a load stage, and the load (load stage) will be described as being connected to equipment operating by supplying commercial power.

In general, the Internet of Things (IoT) is a configuration in which a sensor (device) is connected to an end device of the Internet, and a concept of obtaining information detected by each remotely connected sensor or remotely controlling the sensor. It means a system configuration that is one step higher than the existing Internet.

In addition, commercial power is generally an AC power source and commercially supplied and corresponds to a direct current (DC) power supply.

In addition, as shown in FIG. 4, the outlet unit 1000 includes a commercial power supply unit 1010, a water level monitoring controller 1020, a current consumption detector 1030, a wireless LAN communication unit 1040, and a database (DB: database portion 1050.

In addition, the outlet part 1000 is connected to the first non-contact metal sensor 2030, the second non-contact metal sensor 2040 and the drain pump part 3000, respectively, a lamp, a heating and cooling device, a ventilation device not shown in the drawing Naturally, it can be connected to a boiler or the like.

In addition, the commercial power supply unit 1010 inputs the commercial power of the AC and the switching (switching) processing for supplying the output of the commercial power on or off in the off (off) state by the corresponding control signal do.

That is, the commercial power supply unit 1010 supplies or blocks commercial power to the load side according to the corresponding control signal of the water level monitoring controller 1020.

The water level monitoring controller 1020 includes a commercial power supply unit 1010, a current consumption detector 1030, a wireless LAN communication unit 1040, a database unit 1050, a first non-contact metal sensor 2030, and a second non-contact metal sensor 2040. ), The drain pump unit 3000, and connected to each of the functional units constituting the fluid drainage pump control apparatus 900 using the Internet of Things, and outputs the corresponding control signal to control and monitor the respective operating state.

The water level monitoring control unit 1020 outputs the current supply unit 1030, the first non-contact metal sensor 2030, the second non-contact metal sensor 2040, the drain pump unit 3000 while the commercial power supply unit 1010 outputs Each of the supplied and consumed maximum current and minimum current values are detected and recorded and stored in the allocated area of the database unit, and the additional detected updated values are recorded and stored.

At this time, the water level monitoring controller 1020 generates a corresponding alarm (warning) signal when the detected minimum current value is analyzed as a value exceeding 2 multiples of the corresponding minimum current value stored in the database unit 1050, and the wireless LAN communication unit ( Via 1040, access to the reservoir management headquarters 400 located at a remote location and transmits the alarm situation.

The water level monitoring controller 1020 analyzes the detected current value, and when it is determined that the minimum current value exceeds 1/2000 of the corresponding maximum current value, the commercial power supply unit 1010 supplies the power supply at a specified first time period. The control signal is output and monitored to repeat the off state and the on state.

In this case, the water level monitoring controller 1020 generates an alarm (warning) signal corresponding to the minimum current value exceeding a multiple of 1/2000 of the maximum current value, and the reservoir located at a remote location via the wireless LAN communication unit 1040. Access to the management headquarters 400 and transmits the alarm status notification.

In addition, the first time can be set to any value selected from the range of 10 minutes to 30 minutes, it is relatively preferable to set to 15 minutes can be added or subtracted as necessary.

On the other hand, repeating the off (on) state and the on (on) state of the power supply at a set first time period to the fluid drainage pump control apparatus 900 using the Internet of Things while minimizing the damage caused by leakage current or standby voltage This is to ensure normal operation without failures.

In other words, if the leakage current of a value larger than the allowed range continues to flow, there may be a failure, operation error, or safety accident, and even if the standby voltage is continuously consumed, the power consumption may be greatly reduced. The entire cycle is normally operated normally, and the alarm signal is periodically generated to repeatedly notify the reservoir management headquarters 5000, thereby urging to solve the problem.

Meanwhile, the water level monitoring controller 1020 generates an alarm signal and continues the process of supplying and shutting off the operation power at a first time period for a second time, and is not restored during the second time or the water tank management headquarters. If a corresponding control signal, such as ignored or restored from 5000, is not input, the commercial power supply unit 1010 is controlled to control and monitor the power not to be output.

However, when the corresponding control signal is input from the water tank management headquarters 5000, the alarm signal generation and output are omitted and operate normally.

At this time, the last detected (measured) values may be stored in the update area in the allocated area of the database unit 1050, respectively.

The current consumption detector 1030 detects (measures) a current value consumed by a device or a load terminal in which a plug is inserted into a plug insertion portion provided in the outlet portion 1000 according to a corresponding control signal of the water level monitoring controller 1020. It is applied to the water level monitoring control unit 1020.

The water level monitoring controller 1020 may detect the minimum current, the maximum current, and the standby power consumed by the equipment connected to the load through the current consumption detector 1030, respectively.

Since a technique for detecting the minimum current, the maximum current, and the standby power consumed by the corresponding load (load end, equipment) connected to the current consumption detector 1030 is generally known, a detailed description thereof will be omitted.

In addition, one outlet portion 1000 may form a plurality of plug insertion portions similar to a general power strip, and in this case, a commercial power supply portion 1010 and a current consumption detection portion 1030 having a number corresponding to the number of the plug insertion portions formed. Each can be configured.

The wireless LAN communication unit 1040 is connected to the wireless LAN by the corresponding control signal of the water level monitoring and control unit 1020 and connected to the Internet of Things (IoT) and includes operation information, fault detection signal, alarm signal, remote control signal, data, and the like. Transmit and receive communication signals.

The wireless LAN communication unit 1040 is provided with any one or any one or more of the functional unit selected from the function of performing Wi-Fi, Bluetooth, beacon, near field communication (NFC), Zigbee, infrared communication, similar to the reservoir management headquarters 5000, One or more selected ones of the corresponding functional units provided as described above are simultaneously driven, and a communication signal is transmitted and received through the driven functional units.

The wireless LAN communication unit 1040 writes an input communication signal in a unit standardized frame and transmits the received communication signal to the water tank management headquarters 5000 or receives it from the water tank management headquarters 5000.

The frame is composed of 40 words in total including a 2 word overhead area field, a 30 word signal area field, a 4 word spare area field, and a 4 word error checking area field.

At this time, in the overhead area, the start position of the data, the sequence number of a series of frames, the number of bits in all the data described, the date, the time, the sender address, the receiver address, the sender, the receiver, and the like are described.

In addition, when the communication signal to be transmitted and received cannot be written in the signal area of 30 words, it is operated by writing in a series of frames in the following order.

Here, one word is composed of 10 bytes and one byte is composed of 10 bits. Words, bytes, and bits are units of digital signals.

The transmission and reception of a corresponding communication signal in each standardized frame unit can protect the information from unnecessary noise and illegal hacking while encrypting and decrypting.

That is, the WLAN communication unit 1040 encrypts the frame unit when the communication signal to be transmitted is input, and extracts the necessary communication signal by decrypting the communication signal when the frame unit is received.

On the other hand, in the water tank management headquarters 5000, such encryption and decryption are generated in the same way.

The database unit 1050 generates a corresponding minimum current and a maximum current, operation information, a fault detection signal, a remote control signal, and the like detected from each functional unit by a corresponding control signal of the water level monitoring controller 1020, respectively. Record with time information, save and update.

On the other hand, as shown in Figure 3, the water level detection unit 2000 is connected to the bottom surface of the outlet portion 1000 and is installed in the reservoir 4000 is in a non-contact state of the water level by the fluid introduced into the reservoir 4000 Is detected and notified to the outlet unit 1000.

At this time, the depth measuring cylinder portion 2010 is installed in the reservoir 4000, the inside of the hollow cylindrical shape and the upper end portion is formed in connection with the lower end portion of the outlet portion 1000, the lower end is opened.

The buoy means 2020 floats on the water surface of the fluid introduced into the water reservoir 4000 in the depth measurement cylinder part 2010 and moves vertically in the vertical direction, and includes a metal body 2022 inside the center and the entire outer surface. It is configured to be surrounded by a coating material 2024 that seals the metal body 2022 from being oxidized while generating buoyancy in the fluid.

The metal body 2022 is a metal that reacts to magnetism, and the coating material 2024 should seal the outer circumferential surface of the metal body 2022 and make it easy to float while performing a sealing function for inhibiting oxidation of the metal body 2022.

To this end, the coating material 2024 is 2.5% by weight of zirconia powder, 4.5% by weight of octamethylcyclotetrasiloxane, 2.5% by weight of potassium silicate, 2.5% by weight of attapulgite, polybutene (Polybutene) 1.5 wt%, 2.5 wt% DMAP (dimethylaminopyridine) dissolved in toluene and the remaining polychloroprene (polychloroprene).

At this time, the zirconia powder is added to enhance the adhesion stability while enhancing the anti-oxidation function of the metal body, and since the octamethylcyclotetrasiloxane is a waterproof organic material, the specific surface area of the zirconia powder is reduced so that moisture is not absorbed. The potassium silicate is added to maintain the buoyancy increase effect by moisture proof while inhibiting foreign matter adhesion as a mineral, and the attapulgite is elastic and strengthens the elasticity between the components. It is added to increase the binding force to improve buoyancy, the polybutene (Polybutene) is added to enhance the discoloration resistance and durability, the DMAP (dimethylaminopyridine) dissolved in toluene inhibits high thermal expansion while promoting the curing reaction Vine between compositions It is added to enhance the dingability, the polychloroprene has excellent durability, ozone resistance, chemical resistance, good elasticity and is used as a base material for buoyancy improvement.

In addition, the first non-contact metal sensor 2030 is installed on the upper portion of the outer circumferential surface of the depth measuring cylinder portion 2010 to detect the state where the buoy means 2020 are close and notify the level monitoring control unit 1020 of the outlet portion 1000. do.

It is relatively preferable that the first non-contact metal sensor 2030 and the water level monitoring controller 1020 are wirelessly connected in an RFID manner.

That is, it is relatively preferable that the water level monitoring controller 1020 has a reader configuration of the RFID, and the first non-contact metal sensor 2030 has a tag configuration of the RFID.

In this case, the frequency is 13.56 MHz and passive RF ID method is used, but the communication distance is extended to 50 meters or more.

The RFID method is convenient for waterproofing, installation, operation and maintenance, and the corresponding cost is reduced. On the other hand, it can also be connected by NFC or wired as needed.

The second non-contact metal sensor 2040 is installed at a lower portion of the outer circumferential surface of the depth measuring cylinder part 2010 to detect a state where the buoy means 2020 are in close proximity and notify the level monitoring control unit 1020 of the outlet part 1000.

Since the connection method of the second non-contact metal sensor 2040 and the water level monitoring controller 1020 is the same as the connection method of the first non-contact metal sensor 2030 and the water level monitoring control unit 1020, redundant description thereof will be omitted.

When the first non-contact metal sensor 2030 and the second non-contact metal sensor 2040 are driven in an RFID manner, an antenna through which a radio signal is transmitted and received is greater than the maximum depth on the inner side of the depth measurement cylinder part 2010, respectively. Can be fixed for exposure to high locations.

On the other hand, the outer surface of the depth measuring cylinder portion 2010 may be fixedly installed to be exposed at a position higher than the maximum depth, or may be installed to be exposed in a floating manner, it is very natural that new technology known or expected can be applied.

In addition, the first non-contact metal sensor 2030 and the second non-contact metal sensor 2040 may wirelessly communicate with the outlet part 1000 by using a ray signal or a monochromatic light signal having a specific wavelength which can transmit a signal underwater. It may be.

In addition, the first non-contact metal sensor 2030 and the second non-contact metal sensor 2040 are attached to the outer surface of the depth measuring cylinder portion 2010 and additionally installed a protective film cylinder not shown in detail in the depth measurement The outer surface of the cylindrical portion 2010, the first non-contact metal sensor 2030 and the second non-contact metal sensor 2040 may be sealed to the watertight state and may be configured to transmit and receive a radio wave signal with the outlet portion 1000.

The first non-contact metal sensor 2030 and the second non-contact metal sensor 2040 can be distinguished by an ID, which is a very general technology in an RFID scheme.

The mesh 2050 is installed at the lower end opening of the depth measuring cylinder part 2010 and blocks the inflow of foreign substances while allowing the fluid to flow freely into the depth measuring cylinder part 2010.

In addition, the drain pump unit 3000 is composed of a drain pump 3010 and the drain pipe 3020, the reservoir is connected to the outlet portion 1000, the operating power applied from the outlet portion 1000 and the corresponding control signal (4000) The fluid introduced into the inside is discharged to the outside through the drain pipe 3020 by the driving of the drain pump 3010 which operates as a control signal of the outlet part 1000.

In this case, fluid may be introduced into the reservoir 4000 from the outside through the water supply pipe 3030.

In this case, the drain pump 3010 uses a pump of a vibration pump type that repeats compression-expansion, in particular, without using a pump of a general impeller type.

This implies that the cavitation occurs in the front end of the rotating impeller in the case of the impeller method, and the higher the hydraulic pressure, the lower the suction pressure, and the lower the efficiency. However, FIG. 3 illustrates an impeller drain pump, and the drain pump according to another embodiment of the present invention is as illustrated in FIGS. 6 to 8.

6 to 8, the drain pump 3010 according to another embodiment of the present invention includes a pump housing 3200.

The pump housing 3200 is divided into a lower housing 3210 and an upper housing 3220, and is completely sealed to prevent leakage by adhering an interface surface by an adhesive since it is installed in water after assembly.

At this time, the adhesive is 2.5% by weight of diaryl phthalate, 2.5% by weight of polyisocyanate, 3.5% by weight of cresyl glycid ether, 2.5% by weight of liquefied anhydrous ammonia, 3.5% by weight of SBR (Styrene-Butadiene Rubber), 1.5 wt% of zirconia powder, 3.5 wt% of octamethylcyclotetrasiloxane and polyurethane resin.

Here, the diaryl phthalate is added to improve the adhesion and toughness to increase heat resistance and dimensional stability, including adhesion stability, the polyisocyanate is added to promote curing, the cresyl glycid ether is the interface adhesion The liquefied anhydrous ammonia is added to enhance the waterproofness and adhesion. The SBR (Styrene-Butadiene Rubber) is a synthetic rubber copolymer made of styrene and butadiene, and has good adhesion and wear resistance. And it is added to maintain the aging stability, the zirconia powder is added to enhance the anti-oxidation function of the metal body while improving the adhesion stability, and the specific surface area of the zirconia powder is small because the octamethylcyclotetrasiloxane is a waterproof organic material Moisture is absorbed It is added to maintain the adhesive force by preventing the water.

In addition, a pair of first suction openings 3310 are formed at the front lower side of the lower housing 3210, and a pair of second suction openings 3320 is formed at the front lower side of the upper housing 3220, and the upper portion is A drain port 3330 is formed at an upper side of the housing 3220, and a drain pipe 3020 is connected to the drain hole 3330.

In addition, the lower housing 3210 and the upper housing 3220 may include a pump unit 3400 as illustrated in FIG. 7.

The pump units 3400 are respectively installed and configured to double the pumping capacity by redundancy. However, since the configuration is the same, only one will be described by way of example.

The pump unit 3400 is fixed in a shape that is built in one side of the unit case 3420 of the rectangular box shape, the upper side is open and the first suction port 3310 or the second suction port 3320 And a water suction cylinder 3420 communicating with the nozzle, an injection chamber 3460 separated and fixed to one side of the water suction cylinder 3420, and an injection tube 3480 piped to an upper surface of the injection chamber 3460; And a flexible pumping cylinder 3500 disposed and fixed to both sides of the injection chamber 3460 in a grounded state, and part of which is in communication with the injection chamber 3460, the pumping cylinder 3500 and the injection chamber ( A first check valve 3520 installed at a portion where the 3460 is in communication with each other to discharge water only to the injection chamber 3460, and one end communicates with the water suction tube 3420, and the other end is connected to the pumping cylinder 3500. The connection pipe (3540) piped to communicate with, and is installed on the pipe of the connection pipe (3540) to move the water only to the pumping pipe (3500) The second check valve 3560, one end is fixed on the water suction cylinder (3420) and the length of the elastic piece (3600) fixed to the center of the outer surface of the pumping cylinder 3500, and the elastic piece ( A flow plate 3700 fixed to an end of the 3600, a fixed shaft 3720 fixed to the center of the length of the flow plate 3700, and the rotating rod 3740, the fixed shaft 3720 is eccentrically fixed away from the center ), And a rotary motor 3760 for rotating the rotary rod 3740.

In this case, the coupling relationship between the flow plate 3700, the fixed shaft 3720, and the rotating rod 3740 is well illustrated in FIG. 8.

In addition, the Y-shaped connecting pipe 3800 is connected to the upper end of the injection pipe 3480 to collect the water discharged from each pump unit 3400 installed in the lower housing 3210 and the upper housing 3220 into a drain ( 3330) to be discharged.

That is, the Y-shaped connecting pipe 3800 is connected to the drain 333, and is embedded in the upper housing 3220.

In addition, the connection pipe 3540 is configured as a flexible pipe is configured to ensure the connection stability.

Therefore, when the rotating motor 3760 is rotated, the flow piece 3700 reciprocates from side to side because the fixed shaft 3720 eccentrically fixed to the rotating rod 3740 is displaced within the eccentric range.

The right and left reciprocation of the flow piece 3700 causes the flow of the elastic piece 3600, and thus the elastic pump 3500 is repeatedly pressed by the elastic pump 3600 under pressure. When pressed under pressure, the water inside is discharged through the injection chamber 3460 and the injection pipe 3480 via the first check valve 3520, and when the pressure is released, the water tank 4000 through the connection pipe 3540. Water inside is sucked into the pumping tank 3500.

This process occurs smoothly because two check valves are installed, and the water inside the pumping tank 3500 is injected into the injection chamber 3460, and the water collected in the injection chamber 3460 causes the injection pipe 3480 to flow. It is discharged through the drain pipe 3020.

In particular, this operation is because the two pump units 3400 are operated simultaneously, the drainage capacity is improved by that much.

In addition, the reservoir 400 is any one of a shape selected from a polygonal shape including a circle, a square, and the inside is empty and the housing for storing the fluid, such as plastic, wood, stone, concrete, metal, vinyl material, etc. It may be made of any one or any one or more selected from the materials that can be.

In addition, the water tank management headquarters 5000 is connected to the outlet 1000 and the Internet of Things (IoT) method by a wireless LAN, and transmits and receives the communication signal. Reservoir management headquarters 5000 is made of a computer, there may be an administrator to enter the corresponding control command to quickly perform the necessary actions, or may be automatically processed by the program.

On the other hand, the water tank management headquarters 5000 may download and install the water level management app to the outlet part 1000 as the latest version, and transmit and receive mutual communication signals by the operation of the water level management app.

With reference to the accompanying Figure 5 according to an embodiment of the present invention will be described in detail the operating method of the fluid drainage pump control apparatus using the Internet of Things.

The outlet part 1000, the water level detection part 2000, the drain pump part 3000, the reservoir tank 4000, the reservoir management headquarters 5000, the operation method of the fluid drainage pump control device using the IoT It is determined whether the water level management app is installed (S110). This determination can be made by inputting the corresponding control command to operate the water level management app.

App is a kind of application program and is also called an app, and it is generally given a name that can be easily called in an application field because it is developed and used for various applications.

The above application is called water level management app because the application field is water level management, it can be described as an app in the following description.

If it is determined that the app is not installed in the outlet is connected to the reservoir management headquarters in a wireless LAN, the water level management app is downloaded in a streaming manner and stored in the allocated area and installed in the operating state (S120).

The outlet unit detects the minimum current value and the maximum current value from each sensor function or operation function by the app running in an active state, records them in the assigned area, and when a lower minimum current value or a higher maximum current value is detected. Update and record management (S130). At this time, the detected date and time information are linked and recorded together.

The outlet part analyzes the value of the detected minimum current, and if it is determined that a current value corresponding to twice the minimum current value recorded in the previous step is detected (S140), it is determined that the leakage current flows through the WLAN. Notify the reservoir management office with internet access.

Information informed here is a warning (alarm) signal containing the value of the detected current and the result of the analyzed multiple. At the same time, the outlet unit repeats a process of controlling so that an off state of blocking supply of commercial power is set at a first time period and controlling an on state of supplying again (S150).

The outlet unit analyzes the detected minimum current value and the recorded and stored maximum current value, and determines whether the minimum current value exceeds 1/2000 of the maximum current value (S160).

If it is determined that the minimum current value detected by the outlet portion exceeds 1/2000 of the recorded and stored maximum current value, the reservoir management head connected to the IoT is notified via the wireless LAN.

Information informed here is a warning (alarm) signal containing the value of the detected current and the result of the analyzed multiple. At the same time, the outlet unit repeats a process of controlling so that an off state for blocking supply of commercial power is set at a first time period and controlling an on state for supplying again (S170).

The outlet unit repeatedly checks whether a signal for recovering a fault situation in which an alarm signal is generated is input for a second time (S180).

Here, since the first time value and the second time value and meaning have already been described, duplicate descriptions will be omitted.

If it is determined that the signal to be recovered during the second time by the outlet portion is not input, it is set to cut off the supply of commercial power to the corresponding functional unit to prevent the consumption of standby power.

Therefore, the present invention having the above-described configuration prevents a leakage current from flowing into the reservoir while detecting the leakage current inside the reservoir so that the leakage current does not exceed the allowable range. It monitors the standby power of various installed equipments and cuts them out of unnecessary waste, which reduces the power consumption.

On the other hand, the present invention of the configuration as described above is a sensor that detects the water level of the reservoir is not malfunctioned by foreign substances and leakage current, used in a narrow space and deep depths, long life and remotely connected to the IoT to detect the detected obstacle signal It is an advantage that the necessary measures such as cutting off the standby power by automatically transmitting to the quick action is made.
