Abstract

Technology Field
[0001] The present invention relates to a system and method for controlling the operation of a flood prevention pump. Specifically, the present invention relates to a drainage system related to a flood prevention water tank (e.g., an underground water tank or rainwater tank in a building, a water tank installed in a location adjacent to an underground roadway, etc.) installed in a place with a high risk of flooding in various facilities (e.g., apartments, underground parking lots, buildings, underpasses, tunnels, roads, basin areas, low-lying areas, etc.).
[0002] In the event of an emergency situation such as an accident involving a water supply or drainage tank, or natural disasters such as floods or river overflows, water fills up in a water tank or general water tank buried in a place with a high risk of flooding. The present invention relates to a method for efficiently determining the operation and shutdown schedule of a pump related to drainage equipped in a water tank by taking into account the speed at which the water fills up.
[0003] The drainage management system according to the present invention can be mounted and / or installed in a general drainage system, a sewage system, a rainwater system, a landscaping drainage system, a permanent drainage system, a special drainage system, and other drainage systems. Background Technology
[0004] Recently, due to environmental pollution and abnormal climate conditions, damage caused by localized heavy rainfall is increasing domestically. In particular, flooding of underpasses, underground parking lots, and tunnels resulting from localized heavy rain is causing casualties and property damage. To prevent such damage, there is a growing need for a flood monitoring system capable of monitoring flood-risk areas (e.g., apartments, buildings, underground parking lots, underpasses, tunnels, roads, basin areas, low-lying areas, etc.) and taking measures to block the entry of people, equipment, and vehicles.
[0005] In the case of flood monitoring systems for such facilities, a configuration for detecting or measuring the water level inside the facility may be essential. Conventionally, electrically conductive (electrode rod type) water level detectors were used to measure water levels in underpasses, but this has the disadvantage of only being able to detect whether the water level has reached a predetermined point, rather than measuring the water level itself.
[0006] Furthermore, conventional systems have the disadvantage of being unable to respond quickly to sudden flooding caused by factors such as torrential rain. Conventional systems detect the water level in a tank, and when the water rises to a certain level, a sensor activates to sequentially operate drainage pumps. However, this configuration alone has the disadvantage that it is difficult to prevent flooding when early activation of pumps is required to prepare for a rapid rise in water levels.
[0007] In this regard, Korean Registered Patent Publication No. 10-2654391 (June 22, 2022) serves as background technology. The problem to be solved
[0008] The objective of the present invention to solve the above-mentioned problems is to provide a system and a method for controlling the operation of a flood prevention pump. means of solving the problem
[0009] To achieve the above-mentioned problem, the present specification discloses a system for controlling the operation of a flood prevention pump. A system for managing a flood prevention drainage pump according to embodiments (hereinafter referred to as the "drainage pump management system") may be characterized by comprising: a water level measuring unit that periodically measures the water level of water accumulated in a water tank; a calculation unit that calculates the volumetric velocity of water accumulated in the water tank based on the periodically measured water level and determines the operation schedule of each of a plurality of pumps connected to the water tank based on the calculated volumetric velocity; and a pump control unit that operates or stops the operation of the plurality of pumps according to the operation schedule of each of the determined plurality of pumps.
[0010] Furthermore, the operation unit according to the embodiments may select at least one of the plurality of pumps based on the calculated volumetric velocity, and the pump control unit may be characterized by selecting at least one of the selected pumps.
[0011] Furthermore, the operation unit according to the embodiments may be characterized by selecting at least one of the plurality of pumps based on the drainage speed of each of the plurality of pumps.
[0012] In addition, the operation unit according to the embodiments may be characterized by selecting such that the sum of the drainage speeds of the at least one pump is greater than the calculated volumetric speed.

[0014] Furthermore, the operation unit according to the embodiments may calculate the operating duration of the at least one pump based on the calculated volumetric velocity and the drainage velocity of the selected at least one pump, and the pump control unit may operate the at least one pump during the operating duration.
[0015] Meanwhile, the operation unit according to the embodiments may be characterized by selecting at least one of the plurality of pumps by further considering the drainage speeds of the plurality of pumps.
[0016] Additionally, the operation unit according to the embodiments may be characterized by selecting the first pump when the drainage speed of the first pump is greater than or equal to the volumetric speed, and selecting the second pump when the drainage speed of the first pump is less than the volumetric speed, such that the sum of the drainage speed of the first pump and the drainage speed of the second pump is greater than or equal to the volumetric speed.
[0017] Furthermore, the operating duration of at least one pump may be characterized by being calculated by dividing the sum of the drainage speeds of the selected at least one pump by the volumetric speed. Effects of the invention
[0018] As such, the drainage management system (11) according to the embodiments monitors the rate of increase of water in a water tank in real time in a flood risk area and efficiently controls the operation of the pump based on the monitoring results to prevent flooding.
[0019] The system according to the embodiments enables efficient use of the drainage pump by controlling the drainage pump (10d-1, 10d-2) so as not to repeatedly operate or stop operating it.
[0020] The system according to the embodiments can immediately detect the volumetric velocity of water in a tank to induce a response such as rapid drainage, and helps to efficiently perform an initial response by promptly notifying additional drainage work when flooding is determined to be dangerous.
[0021] In addition, the drainage management system according to the embodiments analyzes changes in water level and water volume velocity in real time, and by utilizing an artificial intelligence model, enables flexible prevention of flooding even in non-linear and sudden situations.
[0022] Furthermore, the drainage management system according to the embodiments can improve the reliability and efficiency of the drainage system by continuously monitoring the performance of the drainage pump and correcting the difference between the actual drainage performance and the maximum drainage performance.

[0029] The present invention relates to a system and method for controlling the operation of a flood prevention actuator (e.g., a pump). Specifically, the present invention relates to a drainage system related to a flood prevention water tank (e.g., an underground water tank in a building, a water tank installed in a location adjacent to an underground road, etc.) installed in a place with a high risk of flooding in various facilities (e.g., apartments, buildings, underground parking lots, underpasses, tunnels, roads, basin areas, low-lying areas, etc.).
[0030] In the event of emergencies such as accidents involving water supply and drainage tanks, or natural disasters like floods or river overflows, water may fill up in tanks or general tanks buried in locations at high risk of flooding; in some cases, sewage or rainwater may fill up due to errors in sumps or other components of permanent drainage systems.
[0031] In this case, the present invention relates to a method for efficiently determining the operation and shutdown schedule of a pump related to drainage provided in a water tank by taking into account the rate at which water rises. The drainage management system according to the present invention may be mounted and / or installed in a general drainage system, a sewage system, a rainwater system, a landscaping drainage system, a permanent drainage system, a special drainage system, and other drainage systems.
[0032] FIG. 1 is a diagram showing the structure of a drainage management system according to embodiments.
[0033] Referring to FIG. 1, a drainage management system (11) for preventing flooding monitors the water level, volume velocity, volume amount, etc. of water being volumemed based on one or more sensors (10a, 10b, 10c, etc.) provided in a water tank (10), and controls a plurality of drainage pumps (10d) provided in the water tank (10). The drainage management system (11) communicates with the water tank (10) installed in a place with a high risk of flooding, periodically monitors the condition of the water tank, and controls the operation and stoppage of the drainage pumps.
[0034] The drainage management system (11) includes a water level measuring unit (110a) that receives data from an ultrasonic sensor (10a) that periodically measures the water level and volume velocity of the water tank (10), a level sensor unit (110b) that receives data from one or more water level sensors (10b) that respond according to the water level of the water filling the water tank (10), and a pump control unit (110c) that controls each of the plurality of pumps (10c) provided in the water tank (10) to operate or stop operation. The drainage management system (11) further includes a calculation unit (111) that determines the operation schedule of the plurality of pumps (10c) in real time based on the water level and volume velocity of the water tank (10) and the volume degree (volume level), and a communication unit (112) that notifies the manager's terminal device of whether the plurality of pumps (10c) are operating and the operation schedule, and receives operation commands for the plurality of pumps (10c) from the manager's terminal device.
[0035] The drainage management system (11) according to the embodiments may be mounted and / or installed in various drainage systems. For example, the drainage management system (11) according to the embodiments may be mounted and / or installed in a general drainage system, a sewage system, a rainwater system, a landscaping drainage system, a permanent drainage system, a special drainage system, other drainage systems (not limited thereto), etc.
[0036] The water tank (10) is a space where water accumulates and includes an ultrasonic sensor (10a), a level sensor (10b), and one or more drainage pumps (10c). The water tank (10) may be a flood prevention water tank buried underground in a place with a high risk of flooding in various facilities (e.g., apartments, buildings, underground parking lots, underground roads, tunnels, roads, basin areas, low-lying areas, etc.) (e.g., an underground water tank or rainwater tank of a building, a water tank installed in a location adjacent to an underground road, etc.) or a general water tank, and may also refer to a water tank, sump, etc. equipped in the drainage system as described above. When water accumulates in a building, underground road, tunnel, road, basin area, low-lying area, etc. due to an accident involving water supply or drainage tank, or due to a flood or river overflow, water moves to the water tank (10) through one or more pipes and accumulates in the water tank (10). The accumulated water is removed through multiple drainage pumps (10c).
[0037] An ultrasonic sensor unit (10a) provided in a water tank (10) measures the volume of water and the volume velocity of the water. The ultrasonic sensor unit (10a) emits ultrasonic waves into the water accumulated in the water tank (10) and detects the signal reflected back to measure the water level accumulated in the water tank (10). The measured water level information is transmitted to the water level measuring unit (110a) of the drainage management system (11).
[0038] A level sensor unit (110b) provided in a water tank (10) detects the volumetric water level of the water being filled. The water tank (10) may have one or more level sensor units (110b) at different heights. When water in the water tank (10) rises to a first height, the first level sensor unit (110b) provided at the first height moves upward due to buoyancy. In response to this upward movement, an electrical or analog signal is generated, and the generated signal is transmitted to the level sensor unit (110b) of the drainage management system (11).
[0039] For example, as shown in FIG. 1, the water tank (10) may be equipped with a level sensor unit (110b) at a first height corresponding to 25% of the water tank (10), a second height corresponding to 50%, a third height corresponding to 75%, and a fourth height corresponding to 100%. If the water in the water tank (10) rises to 60%, which is above the second height, the level sensor units (110b) equipped at the first and second heights move upward due to buoyancy, and as a result, the electrical signal generated by the level sensor units (110b) equipped at the first and second heights is transmitted to the level sensor unit (110b).
[0040] A drainage pump (10c) is provided inside or outside the water tank (10) to remove (move to the outside) the accumulated water. The water tank (10) may be equipped with a plurality of drainage pumps (10c), and a drainage management system (11) may drive some or all of them to control the speed at which water inside the water tank (10) is drained to the outside.
[0041] The calculation unit (111) of the drainage management system (11) receives electrical signals (or data) from the ultrasonic sensor unit (110a) and the level sensor unit (110b) provided in the water tank (10) as described above, and calculates and analyzes the volumetric velocity and volumetric amount of water based on these. The pump control unit (110c) of the drainage management system (11) starts or stops the operation of a plurality of drainage pumps (10d) provided in the water tank (10) based on the analyzed results.
[0042] That is, referring to the embodiment illustrated in FIG. 1, when the water level inside the water tank (10) increases above a certain level, the calculation unit (111) analyzes the data measured by the water level measuring unit (110a) and the level sensor unit (10b) and selects and operates a suitable pump among a plurality of drainage pumps (10d). For example, if the rate of increase of water exceeds the drainage rate of one pump, the calculation unit (111) operates one or more additional pumps to efficiently discharge water.
[0043] The water level measuring unit (110a) of the drainage management system (11) periodically measures the water level of the water tank (10) through an ultrasonic sensor, and the measured data is transmitted to the drainage pump management system (11). The level sensor unit (10b) detects each water level section of the water tank (10) and determines whether the water has reached a set level. The pump control unit (110c) operates or stops a plurality of drainage pumps (10d) according to the operation schedule determined by the drainage pump management system (11).
[0044] The drainage pump management system (11) includes a calculation unit (111) and a communication unit (112). The calculation unit (111) calculates the volumetric velocity of water based on data received from a water level measuring unit (110a) and a level sensor unit (10b), and determines an operation schedule for a plurality of drainage pumps (10d).
[0045] At this time, the calculation unit (111) can minimize the risk of flooding by generating an emergency warning when the rate of increase of water exceeds the maximum drainage rate of specific drainage pumps (10c) and increasing the number of pump operations.
[0046] Furthermore, the calculation unit (111) can send an emergency warning to the manager's terminal device to induce the manager to urgently perform additional drainage work when the rate of increase of water exceeds the sum of the drainage rates of all drainage pumps (10c).
[0047] The communication unit (112) is responsible for data communication between the drainage pump management system (11) and the manager's terminal device, and transmits an alarm when an emergency occurs so that the manager can respond in real time.
[0048] Meanwhile, the rate at which water fills the tank and the change in the water level may be irregular. In light rain conditions, when the rate of increase in water is not high and the increase in the water level is not significant, the rate at which water flows into the tank (10) may be constant, and the change in the water level of the tank (10) may increase linearly. However, in emergency situations (e.g., sudden heavy rain, flooding caused by failure to control the water level of a nearby dam, or other drainage systems malfunctioning or becoming inoperable), the water level of the tank (10) may change abruptly. In such emergency situations, the water level of the tank (10) may not increase linearly, and failure to predict such changes in the rate of increase may lead to a major accident.
[0049] Accordingly, the drainage management system (11) according to the embodiments may further include an artificial intelligence unit (113) that predicts a function of the future water level of the tank based on the results of analyzing the rate of increase of water in real time.
[0050] The artificial intelligence unit (113) includes one or more artificial intelligence models (or machine learning models), and the machine learning models may include, for example, an artificial neural network (ANN) model that predicts a function representing the water level of the water tank (10) at different times, a decision tree model, and a support vector machine (SVM).
[0051] The artificial intelligence unit (113) receives data on the change in water level over a period calculated backward from the current time by a preset period. The artificial intelligence unit (113) receives the data on the change in water level and can predict a function for the change in water level over a preset period in the future from the current time.
[0052] In this case, the operation unit (111) can determine an operation schedule for a plurality of drainage pumps (10d) based on a water level change function predicted by the artificial intelligence unit (113). For example, the operation unit (111) can predict the estimated time required to reach a predefined water level(s) based on the change function, and can start or stop one or more drainage pumps (10d) in accordance with the calculated estimated time.
[0053] Specifically, the calculation unit (111) can predict the current and future water level increase rate based on the change function. If the current or future water level increase rate exceeds the maximum drainage rate of specific drainage pumps (10c), the calculation unit (111) can generate an emergency warning to increase the number of pump operations to minimize the risk of flooding. Additionally, if the current or future water level increase (water increase) rate exceeds the sum of the drainage rates of all drainage pumps (10c), the calculation unit can transmit an emergency warning to the manager's terminal device to induce the manager to urgently perform additional drainage operations.
[0054] Meanwhile, the calculation unit (111) and / or artificial intelligence unit (113) according to the embodiments may further perform an operation to analyze and correct errors that occur due to abnormal operation of the drainage pump (10d). For example, if a difference of more than a certain threshold occurs between the expected drainage speed and the actual drainage speed of a specific drainage pump (10d), the calculation unit (111) may determine that the performance of the drainage pump has deteriorated and send a maintenance notification to the administrator.
[0055] Additionally, the operation unit (111) can adjust the drainage schedule by further considering the performance degradation of the drainage pump (10d). For example, if the drainage speed of a specific drainage pump (10d) decreases, the operation unit (111) can start an additional drainage pump early, and at the same time, store and record the drainage speed of the drainage pump (10d) with reduced performance in a database unit (not shown) or a storage unit (840), and based on this, decide whether to start or stop the drainage pump in the future. In this way, the drainage management system (11) according to the embodiments monitors the rate of increase of water in a water tank in real time in a flood risk area, and efficiently controls the operation of the pump based on the monitoring results to prevent flooding.
[0056] In addition, the drainage management system (11) according to these embodiments analyzes changes in water level and volumetric velocity of water in real time, and by utilizing an artificial intelligence model, it is possible to flexibly prevent flooding even in non-linear and sudden situations.
[0057] Furthermore, the drainage management system according to the embodiments can improve the reliability and efficiency of the drainage system by continuously monitoring the performance of the drainage pump and correcting the difference between the actual drainage performance and the maximum drainage performance.
[0058] FIG. 2 is a diagram showing a method for managing a drainage pump according to one embodiment.
[0059] Specifically, FIG. 2 is a drawing showing a system and method for managing a drainage pump according to the prior art. In the embodiment shown in FIG. 2, the operation of the drainage pump (10d-1) is controlled based only on the water level of the water tank (10).
[0060] According to the embodiments, the water tank (10) is a space where water accumulates and includes a water level measuring unit (110a), a level sensor unit (110b), and a plurality of drainage pumps (10d-1). The water level measuring unit (110a) monitors the water level inside the water tank (10) through an ultrasonic sensor. The level sensor unit (110b) is a sensor installed at each height of the water tank (10) that detects an electrical signal generated when the water rises to a specific height and transmits it to the system. The drainage pumps (10d-1) discharge the water accumulated inside the water tank (10) to the outside and operate sequentially according to the water level.
[0061] In the system according to the embodiments, when the water level reaches a certain height (e.g., 10-1, 10-2), a predetermined pump (e.g., a first pump) is activated according to the certain height. Subsequently, when the water level rises further (e.g., 10-3), a second pump is additionally activated, and when the water reaches the highest level (10-4), an alarm is sent indicating that an emergency drainage operation must be performed.
[0062] However, in the case where the water inside the tank (10) rises rapidly during heavy rain or sudden flooding, the system according to the present embodiments may not be able to start the pumps early because the existing configuration does not take into account the volumetric velocity of the water. For example, even if the volumetric velocity increases steeply before the water reaches the 10-3 level, the second pump is operated only after the water level is reached. Therefore, the initial response may be delayed in a situation where there is a risk of flooding. Consequently, the system according to the present embodiments provides only a step-by-step pump control method based on the water level and has the disadvantage of not being able to reflect the increase in the volumetric velocity of the water in real time. This limitation is a cause of not being able to effectively prevent flooding in urgent situations such as heavy rain.
[0063] Figure 3 below describes the configuration of a system according to embodiments proposed in the present invention and a method for managing an improved drainage pump.
[0064] FIG. 3 is a diagram showing a method for managing an improved drainage pump according to one embodiment.
[0065] Specifically, FIG. 3 is a diagram illustrating a method for managing an improved drainage pump according to an embodiment of the present invention. The drainage management system according to the embodiment provides the effect of quickly responding to the risk of flooding by controlling the operation of the drainage pump (10d-1) by taking into account not only the water level of the water volume in the tank (10) but also the volume velocity.
[0066] Referring to FIG. 3, the drainage management system according to the embodiment analyzes the volumetric velocity of water rising in the water tank (10) and controls the operation or shutdown of the drainage pumps (10d-1, 10d-2) based on the volumetric velocity.
[0067] For example, when the volumetric velocity of the water filling the tank (10) is low (300a), the drainage management system according to the embodiment may operate only one of the plurality of drainage pumps (10d-1, 10d-2). At this time, the drainage management system calculates the volumetric velocity of the water and the drainage velocity of each drainage pump (10d-1, 10d-2). If the drainage velocity of at least one of the drainage pumps (10d-1, 10d-2) is greater than the volumetric velocity of the water, the corresponding drainage pump (e.g., the first pump) may be operated (300a).
[0068] At this time, the drainage management system can further determine the timing for operating and stopping the corresponding drainage pump (e.g., the first pump). At this time, the drainage management system can determine the water level height for operating the drainage pump by considering the difference between the drainage speed of the corresponding drainage pump and the volumetric speed of the water. At this time, the water level height for operating the drainage pump can be determined in proportion to the difference between the drainage speed of the corresponding drainage pump and the volumetric speed of the water. That is, the drainage management system can operate the corresponding drainage pump when the water in the tank (10) is filled to a certain extent.
[0069] When the water level height for operating the drainage pump is calculated as described above, the drainage management system waits for a response from the nearest level sensor unit (110b) that is greater than the water level height, and when the level sensor unit (110b) responds, the drainage pump can be operated.
[0070] For example, if the drainage speed of the drainage pump increases the volumetric velocity of the water significantly, the water in the tank (10) can be removed quickly even when the drainage pump is operated, so the drainage pump can be operated when the water level is somewhat full (i.e., when the water level height required to operate the pump is high). If the drainage speed of the drainage pump increases the volumetric velocity of the water significantly, it may take a long time to remove the water in the tank (10) quickly even when the drainage pump is operated, so the drainage pump can be operated even when the water level is low (i.e., when the water level required to operate the pump is low).
[0071] Due to this configuration, the system according to the embodiments enables efficient use of the drainage pumps by controlling the drainage pumps (10d-1, 10d-2) so as not to repeatedly operate or stop operating them.
[0072] The drainage management system needs to stop the operation of the drainage pumps (10d-1, 10d-2) when all the water in the tank (10) has been removed after the drainage pumps have been operated. Accordingly, the drainage management system can further determine the time for stopping the operation (or the duration of operation) of the operated drainage pumps. At this time, the duration of operation can be calculated by dividing the volume of water in the tank (10) by the value obtained by subtracting the volumetric velocity of the water from the drainage velocity of the corresponding drainage pump.
[0073] Meanwhile, when the volumetric velocity of the water filling the tank (10) is moderate (300b), the drainage management system according to the embodiment can operate at least two of the plurality of drainage pumps (10d-1, 10d-2). That is, when the volumetric velocity of the water filling the tank (10) exceeds the drainage velocity of all drainage pumps, at least two drainage pumps must be operated to achieve drainage. Accordingly, the drainage management system can calculate the volumetric velocity of the water and the drainage velocity of each drainage pump (10d-1, 10d-2), and then select two or more drainage pumps to derive a drainage velocity that exceeds the volumetric velocity of the water.
[0074] For example, when the first drainage pump (10d-1) and the second drainage pump (10d-2) are in operation, the sum of the drainage speeds of the two drainage pumps (10d-1, 10d-2) can be greater than the volumetric speed of water, so both drainage pumps can be operated (300b).
[0075] In this case as well, the drainage management system can further determine the timing for operating and stopping the corresponding drainage pumps (e.g., the first pump and the second pump). At this time, the drainage management system can determine the water level height for operating the drainage pumps by considering the difference between the sum of the drainage speeds of the corresponding drainage pumps and the volumetric speed of the water. At this time, the water level height for operating the drainage pumps can be determined in proportion to the difference between the drainage speed of the corresponding drainage pumps and the volumetric speed of the water. That is, the drainage management system can operate the corresponding drainage pumps when the water in the tank (10) is filled to a certain extent.
[0076] On the other hand, if the volumetric velocity of the water filling the tank (10) is high (300c), the drainage management system according to the embodiment may not reduce the volume of water even if all drainage pumps are operated. That is, if the volumetric velocity of the water filling the tank (10) exceeds the sum of the drainage speeds of all drainage pumps, drainage may not occur even if all drainage pumps are operated. Therefore, in this case, the drainage management system may operate all drainage pumps (10d-1, 10d-2) and at the same time notify the manager's terminal that an emergency drainage operation (additional drainage operation) is required.
[0077] In this case, the drainage management system can preferably immediately activate the corresponding drainage pumps (e.g., the first pump and the second pump). At this time, the drainage management system can calculate the remaining time until the water in the tank (10) is filled to 100% based on the difference between the volumetric velocity of the water and the total drainage velocity (the sum of the drainage velocity of all drainage pumps), and can notify the manager of the remaining time to the terminal device.
[0078] Due to this configuration, the system according to the embodiments can immediately detect the volumetric velocity of water in the tank to induce a response such as rapid drainage, and helps to efficiently perform an initial response by promptly notifying additional drainage work when flooding is determined to be dangerous.
[0079] As described above, the system according to the embodiments compensates for the disadvantages of the prior art and provides the effect of minimizing flood damage in urgent situations such as heavy rain or floods through the early activation and efficient operation of a drainage pump considering volumetric velocity.
[0080] Hereinafter, FIG. 4 describes the operation of a system according to embodiments in the case where two drainage pumps exist in the water tank (10). Also, FIG. 5 describes the operation of a system according to embodiments in the case where n drainage pumps exist in the water tank (10).
[0081] FIG. 4 is a flowchart illustrating an example of the operation of a drainage pump management system according to embodiments.
[0082] Specifically, FIG. 4 shows a flow of operation for determining whether to operate the drainage pumps and providing an emergency drainage operation notification by considering the volumetric velocity of the water when two drainage pumps (10d-1, 10d-2) are provided in the water tank (10).
[0083] Referring to FIG. 4, the drainage pump management system first calculates the volumetric velocity (V) of water flowing into the water tank (10) (400). The volumetric velocity (v) is calculated by the calculation unit (111) based on data received from the water level measuring unit (110a).

The volumetric velocity (v) + If it exceeds, the operation unit (111) determines the simultaneous operation of the first pump (10d-1) and the second pump (10d-2) and at the same time notifies the manager's terminal device that emergency drainage work is required (404c, 407).
[0086] Subsequently, the drainage pump management system [manages] the operating duration of the activated drainage pump ( Calculate ) (405).

[0089] The system according to the embodiments reflects the volumetric velocity of water in real time, enabling the optimal operation of drainage pumps and rapid emergency drainage operations. The system according to the embodiments provides the effect of minimizing flood damage in urgent situations such as heavy rainfall or floods.
[0090] FIG. 5 is a flowchart illustrating another example of the operation of a drainage pump management system according to embodiments.
[0091] Specifically, FIG. 5 shows a flow of operation for determining whether to operate the drainage pumps and providing an emergency drainage operation notification by considering the volumetric velocity of the water when n drainage pumps (10d-1, 10d-2, ..., 10d-n) are provided in a water tank (10).
[0092] Referring to FIG. 5, the drainage pump management system first calculates the volumetric velocity (v) of water flowing into the water tank (10) (500). The calculation unit (111) calculates the volumetric velocity (v) based on data received from the water level measuring unit (110a). Subsequently, the calculation unit (111) calculates the calculated volumetric velocity (v) and the drainage velocity (10d-1, 10d-2, ..., 10d-n) of each drainage pump ( , , ... , By comparing ), it is possible to determine whether at least one of the multiple drainage pumps is operating.
[0093] First, the calculation unit (111) determines that the volumetric velocity (v) is the drainage velocity (10d-1) of the first pump (10d-1). Determine if it is greater than ) (501). If volume velocity (v) is If it is less than or equal to, the calculation unit (111) determines the independent operation of the first pump (10d-1) (504a). On the other hand, the volumetric velocity (v) If it exceeds, the calculation unit (111) calculates that the volumetric velocity (v) is the sum of the drainage velocity of the first pump (10d-1) and the second pump (10d-2). + It additionally determines whether it exceeds ) (502).
[0094] The volumetric velocity (v) class + If it is in between, the operation unit (111) determines the simultaneous operation of the first pump (10d-1) and the second pump (10d-2) (504b). The volumetric velocity (v) + If it exceeds, the calculation unit (111) determines that the volumetric velocity (v) is the sum of n pump drainage velocity ( + + ... + It repeatedly determines whether it exceeds (503). If the volumetric velocity (v) is less than or equal to the sum of the drainage speeds of n pumps, the calculation unit (111) operates the required number of pumps to discharge water (504c). On the other hand, if the volumetric velocity (v) exceeds the sum of the drainage speeds of all pumps, the calculation unit (111) operates all pumps and simultaneously notifies the manager's terminal device that emergency drainage work is required (504d, 507).
[0095] Subsequently, the drainage pump management system [manages] the operating duration of the activated drainage pump ( Calculate ) (505). Operation duration ( ) is calculated by considering the volume of water in the tank (10) and the drainage speed of each drainage pump, and can be derived based on the difference between the volumetric speed of water and the drainage speed. Afterward, when the operation duration is calculated, the drainage management system operates or stops the operation of the drainage pumps according to the pump operation schedule (506).
[0096] The system according to the embodiment enables a rapid response in situations such as emergency drainage operations by efficiently controlling n pumps by reflecting the volumetric velocity of water in real time. Accordingly, the present invention provides the effect of minimizing flood damage in urgent situations such as torrential rain or floods.
[0097] Meanwhile, the rate at which water fills the tank and the change in the water level may be irregular. In light rain conditions, when the rate of increase in water is not high and the increase in the water level is not significant, the rate at which water flows into the tank (10) may be constant, and the change in the water level of the tank (10) may increase linearly. However, in emergency situations (e.g., sudden heavy rain, flooding caused by failure to control the water level of a nearby dam, or other drainage systems malfunctioning or becoming inoperable), the water level of the tank (10) may change abruptly. In such emergency situations, the water level of the tank (10) may not increase linearly, and failure to predict such changes in the rate of increase may lead to a major accident.
[0098] Accordingly, the drainage management system (11) according to the embodiments may further include an artificial intelligence unit (113) that predicts a function of the future water level of the tank based on the results of analyzing the rate of increase of water in real time.
[0099] In FIG. 6 below, the structure and operation of the artificial intelligence unit (113) provided in the drainage management system (11) according to the embodiments will be described in detail.
[0100] FIG. 6 shows the structure and operation of the artificial intelligence unit according to the embodiments.
[0101] Referring to FIG. 6, the artificial intelligence unit (113) according to the embodiment includes a data preprocessing unit (113a), a learning unit (113b), and an artificial intelligence model (113c). The data preprocessing unit (113a) generates input data for the artificial intelligence model (113c) and refines the hourly water level data and inflow velocity data collected from the water level measurement unit (110a) so that the model can use them for learning and prediction.
[0102] The learning unit (113b) can perform the function of additionally training the artificial intelligence model (113c) based on real-time or pre-trained data. For example, if the pattern of water level change of the water tank (10) during a specific period appears differently from the existing training data, the learning unit (113b) can correct the artificial intelligence model (113c) by reflecting the new data.
[0103] The artificial intelligence model (113c) is a model that predicts changes in the water level of the water tank (10) over time, and may include machine learning algorithms such as an artificial neural network (ANN), a decision tree, and a support vector machine (SVM). The artificial intelligence model (113c) receives water level change data for a period calculated backward from the current time by a preset period, and can derive a function that predicts future water level changes based on this.
[0104] Accordingly, the computation unit (111) can determine the operation schedule of the drainage pumps (10d) based on the water level change function predicted by the artificial intelligence unit (113). For example, the computation unit (111) can predict the expected time to reach a predefined water level(s) from the change function and start or stop one or more drainage pumps (10d) in accordance with the expected time. Additionally, if the current or future rate of increase in water level exceeds the maximum drainage rate of specific drainage pumps (10d), the computation unit (111) can generate an emergency warning to increase the number of pump operations or notify the manager's terminal device to perform emergency drainage operations.
[0105] Due to this configuration, the drainage management system (11) according to the embodiment can analyze data in real time even in situations of irregular water level changes and determine the optimal operating schedule of the drainage pump to minimize the risk of flooding.
[0106] FIG. 7 shows an artificial intelligence unit according to embodiments predicting a water level change function in real time and an operation unit based on the prediction result.
[0107] Specifically, FIG. 7 is a diagram showing the operation in which an artificial intelligence unit (113) according to an embodiment of the present invention predicts a water level change function in real time, and a calculation unit (111) determines whether to operate a drainage pump (10d) based on the prediction result.
[0108] Referring to FIG. 7, FIG. 7(A), FIG. 7(B), and FIG. 7(C) each show the artificial intelligence unit (113) detecting in real time that the water level increase pattern changes over time, and the operation of the calculation unit (111) according to the detected result.
[0109] Referring to FIG. 7, the vertical axis of the graph represents the water level of the tank (10), and the horizontal axis represents the passage of time. 701 represents a specific reference water level (e.g., a dangerous water level).
[0110] The artificial intelligence unit (113) predicts a future water level change function (70b) based on water level change data prior to the current time.
[0111] FIG. 7(A) illustrates a situation in which the water level of the tank (10) increases linearly based on the current time. At this time, the artificial intelligence unit (113) according to the embodiments can predict a future water level change function (70b) based on the water level change data (70a) up to that point, and the calculation unit (111) can determine whether to operate the drainage pump (10d) or determine the time to operate it based on the predicted function (70b).
[0112] For example, the operation unit (111) according to the embodiments can determine the operation and shutdown schedule of each drainage pump by comparing the volumetric velocity of water and the drainage velocities (or the sum thereof) of each drainage pump at specific points in time in the present and future.
[0113] FIG. 7(B) illustrates a situation where the water level of the tank (10) increases non-linearly based on the current time. At this time, the artificial intelligence unit (113) according to the embodiments can confirm that the water level increase pattern (71a) is gradually accelerating based on the water level change data up to that point, and the computation unit (111) according to the embodiments can predict the future water level change function (70b).
[0114] At this time, the future water level change function (70b) may cross a specific water level (70b), and the point of intersection may be within a preset time range from the current time. In this case, the operation unit (111) according to the embodiments may determine the early operation of the drainage pump (10d).
[0115] FIG. 7(C) illustrates a situation where, based on the current time, the water level of the tank (10) increases non-linearly and additional drainage work is required. The artificial intelligence unit (113) can analyze the water level change data up to that point and detect cases where the water level increase pattern (72a) shows a rapid form.
[0116] If, by the predicted water level change function, the time to reach a specific danger level (701) is within a preset time from the current time (i.e., when an emergency situation is recognized), the operation unit (111) can immediately control the operation of multiple drainage pumps (10d) and notify the manager's terminal device that emergency drainage work is required.
[0117] Meanwhile, referring to FIG. 7, the artificial intelligence unit (113) according to the embodiments can predict multiple future water level change functions (70b). At this time, the artificial intelligence unit (113) can predict a first water level change function assuming a best-case scenario and a second water level change function assuming a worst-case scenario, respectively (70c, 71c).
[0118] Meanwhile, the calculation unit (111) and / or artificial intelligence unit (113) according to the embodiments may further perform an operation to analyze and correct errors that occur due to abnormal operation of the drainage pump (10d). For example, if a difference of more than a certain threshold occurs between the expected drainage speed and the actual drainage speed of a specific drainage pump (10d), the calculation unit (111) may determine that the performance of the drainage pump has deteriorated and send a maintenance notification to the administrator.
[0119] Additionally, the operation unit (111) can adjust the drainage schedule by further considering the performance degradation of the drainage pump (10d). For example, if the drainage speed of a specific drainage pump (10d) decreases, the operation unit (111) can start an additional drainage pump early, and at the same time, store and record the drainage speed of the drainage pump (10d) with reduced performance in a database unit (not shown) or a storage unit (840), and based on this, decide on the operation and shutdown of the drainage pump in the future.
[0120] In this way, the drainage management system according to the embodiments can improve the reliability and efficiency of the drainage system by continuously monitoring the performance of the drainage pump and correcting the difference between the actual drainage performance and the maximum drainage performance.
[0121] In this way, the drainage management system (11) according to an embodiment of the present invention can effectively prevent flood damage by utilizing an artificial intelligence unit (113) to predict future water level changes in real time and determining an optimal drainage pump operation strategy through a computation unit (111).
