Description

Technology Field

[0001] The present invention relates to a submersible pump operating system, and more specifically, to a submersible pump operating system capable of controlling the timing of operation of a submersible pump by predicting the water level. Background Technology

[0003] Recently, localized torrential rains caused by climate change (abnormal weather) have been occurring frequently, and flood damage in urban and rural areas due to these heavy rains is increasing every year.

[0004] Therefore, various measures to prepare for flood damage are being actively sought.

[0005] In particular, active research and development is being conducted on submersible pump operation systems that control the timing of pump operation by predicting water levels.

[0007] A conventional submersible pump operating system comprises a water level sensor installed within a sump to detect the water level, a pump control device that analyzes water level information received from the water level sensor to control the timing of the pump's operation, and a pump installed within the sump to perform drainage operations according to the control of the pump control device. By predicting the amount of water inflow from the water level detection information received through the water level sensor and intelligently controlling the timing of the pump's operation according to the predicted amount of water inflow, the number of pump operations is minimized, thereby extending the lifespan of the pump.

[0008] Such an underwater pump operating system is disclosed in Registered Patent Publication No. 10-2719585.

[0010] However, the above submersible pump operation system has a problem in that, since it controls the timing of pump operation based solely on the prediction of water inflow, there is a high possibility of flooding or inundation occurring due to a sudden rise in water level if the prediction of water inflow deviates even slightly due to various variables.

[0011] This ultimately results in a decrease in the functionality and usability of the submersible pump operating system. The problem to be solved

[0013] The present invention was devised to solve the above problems and provides a submersible pump operating system capable of actively responding even when the amount of water inflow deviates from the predicted range. means of solving the problem

[0015] The technical feature of the submersible pump operating system according to the present invention for solving the above problem is that it comprises: a submersible pump unit installed in a sump; a water level sensing unit that measures the water level in the sump; a pump operation prediction unit that predicts the operating time of the submersible pump unit in real time in conjunction with the water level sensing unit; and a pump operating unit that operates the submersible pump unit in advance of the operating time predicted by the pump operation prediction unit. Effects of the invention

[0017] The submersible pump operating system according to the present invention operates the submersible pump unit ahead of the operating time predicted by the pump operating unit and the pump operating prediction unit, thereby actively responding to the situation even if the water inflow exceeds the predicted range, and preventing floods or inundation.

[0018] As a result, it is possible to respond more efficiently to disaster situations, such as torrential rain. Brief explanation of the drawing

FIG. 2 is a graph showing the predicted water level curve and the operating water level curve of the submersible pump operating system according to the present invention. FIG. 3 is a block diagram illustrating a control method of an underwater pump operating system according to the present invention. Specific details for implementing the invention

[0021] Below, the underwater pump operating system according to the present invention will be described in detail with reference to the attached drawings.

[0023] As illustrated in FIGS. 1 and 2, the underwater pump operation system according to the present invention comprises: an underwater pump unit (10); a water level sensing unit (20); a pump operation prediction unit (30) that generates a predicted water level curve in conjunction with the water level sensing unit (20); and a pump operation unit (40) that generates an operation water level curve in conjunction with the pump operation prediction unit (30).

[0025] The submersible pump unit (10) is stably installed in a collection well (W) into which water (rainwater or sewage) flows.

[0026] This submersible pump unit (10) is composed of a first pump (12), a second pump (12), and a third pump (16), and the first, second, and third pumps (12, 14, 16) are operated sequentially by the pump operation unit (40). That is, the first pump (12) is operated according to an operating water level curve that precedes the predicted water level curve by a certain time (tα), the second pump (14) is operated according to an operating water level curve that precedes the predicted water level curve regenerated by reflecting the actual water level changed by the operation of the first pump (12) by a certain time (tα), and the third pump (16) is operated according to an operating water level curve that precedes the predicted water level curve regenerated by reflecting the actual water level changed by the operation of the second pump (14) by a certain time (tα).

[0027] To explain this more specifically, the first pump (12) is operated at an operating time (t1') on the operating water level curve that is a certain time (tα) ahead of the operating time (t1) on the predicted water level curve, and is also operated at an operating water level (h1') on the operating water level curve that is a certain water level lower than the operating water level (h1) on the predicted water level curve; the second pump (14) is operated at an operating time (t2') on the operating water level curve that is a certain time (tα) ahead of the operating time (t2) on the predicted water level curve regenerated by the operation of the first pump (12), and is also operated at an operating water level (h2') on the operating water level curve that is a certain water level lower than the operating water level (h2) on the predicted water level curve; and the third pump (16) is operated on an operating water level curve that is a certain time (tα) ahead of the operating time (t3) on the predicted water level curve regenerated by the operation of the second pump (14). It is operated at the operating time (t3') and also at the operating level (h3') on the operating level curve, which is a certain level lower than the operating level (h3) on the predicted level curve.

[0028] Meanwhile, the number of installed submersible pump units (10) can be appropriately changed as needed.

[0030] The water level sensing unit (20) is for measuring the water level in the sump (W) in real time, and through this water level sensing unit (20), it is possible to accurately check the change in the water level in the sump (W).

[0031] Meanwhile, various types of known water level sensing units (20) can be selectively applied.

[0033] The pump operation prediction unit (30) generates a predicted water level curve that can predict the water level change over time within the sump (W) by reflecting the water level measured by the water level sensing unit (10), and plays the role of predicting the operation time of the submersible pump unit (10) in real time.

[0034] These predicted water level curves are generated by an artificial intelligence (AI)-based water level prediction system.

[0035] That is, the predicted water level curve is generated by an algorithm that is repeatedly learned based on the actual water level value measured by the water level sensing unit (20) and the predicted water level value predicted by the simulator for generating learning data. At this time, the main parameters of the simulator include water level, water level noise (large noise and small noise), danger level (HWL), pump stop level (LWL), pump operating level, pump volume, and discharge volume, and in particular, the water level noise is intended to reflect the actual water level situation.

[0036] And the operating time of the submersible pump unit (10) is changed in real time according to the change in slope (water level) of the predicted water level curve generated by the pump operation prediction unit (30). For example, if the change in slope of the predicted water level curve is large, the amount of water (rainwater or sewage) inflow is rapidly increasing, and in this case, in order to respond to the rapid change in water level, the operating time (operating time and operating water level) of the submersible pump unit (10) is changed in real time and operated earlier than the previously set time.

[0038] The pump operation unit (40) plays the role of operating the underwater pump unit (10) ahead of the operating time predicted by the pump operation prediction unit (30).

[0039] This pump operating unit (40) generates an operating water level curve that precedes the predicted water level curve generated by the pump operating prediction unit (30) by a certain time (tα), and operates the underwater pump unit (10) according to this operating water level curve.

[0040] Accordingly, even if the amount of water (rainwater or sewage) flowing into the catch basin (W) deviates from the predicted range based on the predicted water level curve, it is possible to actively respond to this and efficiently prevent floods or inundation, thereby enabling simple and efficient response to disaster situations such as the occurrence of torrential rain.

[0042] The control method of the submersible pump operating system described above is explained below with reference to Fig. 3.

[0043] ① Water level measurement step (S1); a step of measuring the water level in the sump (W) through the water level sensing unit (20).

[0044] ② Pump operation prediction step (S2); a step of generating a predicted water level curve that can predict the change in water level in the sump (W) by reflecting the water level measured by the water level sensing unit (20) through the pump operation prediction unit (30), and predicting the timing of operation of the submersible pump unit (10) in real time according to this predicted water level curve.

[0045] ③ Pump operation step (S3); a step of generating an operation level curve that precedes the predicted water level curve generated in the pump operation prediction unit (30) through the pump operation unit (40) by a certain time (tα), and actually operating the submersible pump unit (10) in real time according to this operation level curve.

[0046] By sequentially following the above steps, the operation system of the submersible pump can be easily controlled. Explanation of the symbols
