[0026] The present invention will be described in detail below with reference to the drawings. In describing the specific embodiments below, various specific details have been included to explain the invention more specifically and to aid in understanding. However, a reader with sufficient knowledge in the art to understand the invention will recognize that it can be used without these various specific details. In some cases, it is noted in advance that commonly known parts that are not significantly related to the invention have been omitted to prevent confusion in describing the invention.

[0027] FIG. 1 is a drawing for explaining a relay pump station operating system according to one embodiment of the present invention, and FIG. 5 is a drawing for explaining the operation of elements constituting an embedded eco-friendly relay pump station operating system according to one embodiment of the present invention.

[0028] Referring to FIGS. 1 and FIGS. 5, a relay pump station operating system according to one embodiment of the present invention may include a central control unit (100), a relay pump station (200), and a relay pump station monitoring control panel (300).

[0029] A relay pumping station (200: A, B, C, D, E) (the drawing number of the relay pumping station is designated as '200' unless there is no practical benefit in distinguishing it) stores sewage in a storage tank (201), and when the sewage stored in the storage tank (201) reaches a standard water level or higher, it pumps the sewage and discharges it to a sewage treatment plant. Here, the discharged sewage can be transported through a pipe (L), and a flow meter (not shown) for measuring the flow rate of the sewage may be installed in the pipe (L).

[0030] In this embodiment, the relay pump station (200) may receive sewage directly from a sewage source or receive sewage from another relay pump station (200). For example, relay pump station (200)(A), relay pump station (200)(B), relay pump station (200)(E), and relay pump station (200)(D) receive sewage directly from a sewage source, and relay pump station (200)(C) receives and stores sewage from other relay pump stations (200) (relay pump station (200)(E), and relay pump station (200)(D)).

[0031] The relay pump station monitoring control panel (300: a, b, c, d, e) (the drawing number of the relay pump station monitoring control panel is designated as '300' unless there is no practical benefit in distinguishing it) monitors the relay pump station (200), determines whether it is normal based on the monitoring results, and transmits the determination result to the central control unit (100). In addition, if the relay pump station monitoring control panel (300) determines that the sewage relay pump station (200) is not normal, it transmits information that can identify the location of the sewage relay pump station (200) to a terminal—an engineer terminal (500)—held by the engineer in charge of the sewage relay pump station (200). The engineer terminal (500) may be a device such as, for example, a desktop computer, a laptop, a smartphone, or a PDA.

[0032] According to the present embodiment, the relay pump station monitoring control panel (300) monitors the condition of the relay pump station (200) to determine whether the relay pump station (200) is functioning normally, and determines whether it is functioning normally based on the monitoring results. The subjects of monitoring are, for example, the load applied to the motor (203) that pumps sewage, the level of sewage stored in the storage tank (201), and the operating status of the components used for operating the relay pump station (200).

[0033] Additionally, the relay pump station monitoring control panel (300) calculates the cumulative amount of sewage discharged to the sewage treatment plant—the cumulative sewage treatment amount—and transmits it to the central control unit (100). For example, the relay pump station monitoring control panel (300) periodically (daily, weekly, monthly, quarterly, or annually) calculates the cumulative sewage treatment amount and transmits it to the central control unit (100).

[0034] In one embodiment, the relay pump station monitoring control panel (300) can determine whether there is a sewage leak in the pipe (L) connected to each relay pump station (200) and transmit information regarding the leak status to the central control unit (100) or the manager of each relay pump station monitoring control panel (300).

[0035] In this regard, as an example, FIG. 1 illustrates one or more leak detection devices (250) connected to a pipe connected to a relay pump station (200) (B). Generally, a manhole is installed in the ground where the path of the pipe (L) bends, and a worker buries the pipe by connecting the bending pipes using a connecting member inside the manhole. However, leaks frequently occur at the connection point due to problems such as incorrect connection of the connecting member or twisting of the connection part.

[0036] In one embodiment of the present invention, one or more leak detection devices (250) are installed in the manhole area where the pipe bends. For example, a leak probe can be installed by burying it around the manhole area at a depth of approximately 2 to 3 meters from the ground. As shown in FIG. 1, the leak detection device (250) can be connected to a relay pump station monitoring control panel (300) via wired and / or wireless connection, and can transmit measurement values ​​regarding leak detection to the relay pump station monitoring control panel (300).

[0037] The leak detection device (250) is generally equipped with a sensor that measures moisture (water), but in an alternative embodiment, it may measure other components to accurately detect sewage. For example, the leak detection device (250) may be equipped with one or more sensors that detect components such as phosphorus, nitrogen, sodium, and organic compounds, and by detecting these components, it can accurately determine whether there is a leak in the sewage pipe (L).

[0038] Although the leak detection device (250) is illustrated only for the relay pump station (200)(B) in FIG. 1, those skilled in the art will understand that a leak detection device (250) can be installed on the pipe (L) connected thereto for each relay pump station (200), and can be configured so that a measurement signal is transmitted to each relay pump station monitoring and control panel (300) that manages each relay pump station (200).

[0039] The central control unit (100) transmits the setting information of the relay pump station operating system and the engineer information to the relay pump station monitoring control panel (300). The setting information of the relay pump station operating system includes the number of motors (203) installed in the relay pump station (200) and the type of sensors. The engineer information may be the contact information (e.g., a smartphone phone number) of an engineer who manages and repairs the corresponding relay pump station (200). When there is a change in the setting information of the relay pump station operating system and the engineer information, the central control unit (100) transmits the changed information to the relay pump station (200). For example, if there is a change in the setting information or engineer information of the relay pump station (200)(A), the central control unit (100) transmits it to the relay pump station monitoring control panel (300)(a).

[0040] The central control unit (100) also receives monitoring results and judgment results, as well as the amount of sewage leakage treatment, from the remote monitoring control panel of each relay pumping station (200). The central control unit (100) can determine whether there is sewage leakage based on the amount of sewage leakage treatment received from the remote monitoring control panel of each relay pumping station and reflect this in the establishment of an operation plan for the relay pumping station (200).

[0041] To determine whether there is a leak, the central control unit (100) receives the cumulative sewage treatment volume from each relay pumping station (200) and receives the measurement results from a flow meter (not shown) installed in the pipe (L) through which the sewage travels to measure the flow rate of the sewage. The central control unit (100) can determine whether there is a sewage leak in real time and periodically by comparing the total flow rate of sewage flowing into the sewage treatment plant (measured by the flow meter (not shown)) with the sum of the cumulative sewage treatment volumes received from the relay pumping stations (200). For example, the central control unit (100) can determine whether there is a sewage leak in real time by comparing the total flow rate of sewage flowing into the sewage treatment plant (measured by the flow meter) with the sum of the cumulative sewage treatment volumes received from the relay pumping stations (200) on a weekly, monthly, or yearly basis.

[0042] In addition, the central control unit (100) can determine whether to add a new relay pumping station (200) based on the accumulated sewage processing volume received from the relay pumping stations (200).

[0043] Below, the relay pump station (200), the relay pump station monitoring and control panel (300), and the central control unit (100) will be described in more detail with reference to other drawings.

[0044] FIG. 2 is a drawing for explaining a relay pump station (200) according to one embodiment of the present invention.

[0045] Referring to FIG. 2, a relay pump station (200) according to one embodiment of the present invention may include a storage tank (201) for storing sewage, a motor (203) for pumping sewage stored in the storage tank (201), and water level measuring sensors (205, 207). Operation control and monitoring of the relay pump station (200) according to one embodiment of the present invention are performed by a remote pump station monitoring and control panel.

[0046] In this embodiment, one or more motors (203) may be installed, and when multiple motors (203) are installed, they operate alternately with each other. The relay pump station monitoring control panel (300) controls the multiple motors (203) to operate alternately. For example, the relay pump station monitoring control panel (300) can control the alternating supply of power to the motors (203).

[0047] Although not illustrated in FIG. 2, a device such as a power meter for measuring power (or current) supplied to the motor (203) is provided in the relay pump station (200), and the measurement result of such power meter is provided to the relay pump station monitoring control panel (300).

[0048] In this embodiment, the result sensed by the water level measuring sensor (205, 207) is provided to the relay pump station monitoring control panel (300), and the water level measuring sensor (205, 207) may be a contact-type water level measuring sensor (207) and a non-contact-type water level measuring sensor (205).

[0049] Examples of water level measuring sensors (205, 207) may include an ultrasonic sensor (205) and a roly-poly sensor (207). The ultrasonic sensor (205) is an example of a non-contact water level measuring sensor (205) configured to emit ultrasonic waves toward the bottom of the storage tank (201) and receive ultrasonic waves reflected from the bottom. The roly-poly sensor (207) (often called a 'roly-poly level switch' or 'roly-poly level sensor') is an example of a contact water level measuring sensor (207) configured such that a float moves up and down due to buoyancy, and the water level is measured by mechanically and / or electrically recognizing this movement. In this embodiment, a plurality of roly-poly sensors (207) are installed at each predetermined height (e.g., HH, H, L, LL) of the storage tank (201). Since the ultrasonic sensor (205) and the roly-poly sensor (207) used in this embodiment are widely known devices, a detailed description will be omitted.

[0050] FIG. 3 is a drawing for explaining a relay pump station monitoring control panel (300) according to one embodiment of the present invention.

[0051] Referring to FIG. 3, the relay pump station monitoring control panel (300) may include a remote monitoring controller (400), a case (not shown) for storing the remote monitoring controller (400), a power meter (not shown), and a cable (not shown) for receiving power. Meanwhile, FIG. 3 illustrates an exemplary appearance of the relay pump station monitoring control panel (300) and an exemplary appearance of the remote monitoring controller (400) for easy understanding of the present invention, and those skilled in the art to which the present invention belongs will easily understand that the devices thus illustrated are exemplary.

[0052] The relay pump station monitoring control panel (300) can transmit and receive data with an engineer terminal (500) and a central control unit (100) through a communication network. Here, the term 'communication network' refers to any facility that supports the transmission and reception of data via wired and / or wireless means—including any programs, machines, electrical and electronic devices, base stations, and communication cables that support communication—and such a communication network supports the mutual transmission and reception of data via wired and / or wireless means to a wide area network (WAN), a metropolitan area network (MAN), a local area network (LAN), and / or a personal network (PAN).

[0053] According to the present embodiment, the remote monitoring controller (400) is configured as an embedded eco-friendly type, and when an engineer installs the remote monitoring controller (400) in the relay pump station monitoring control panel (300), the installation can be completed by simply setting the operating mode with a simple device such as a DIP switch and connecting the power cable without the need to install a separate program.

[0054] According to the present embodiment, the remote monitoring controller (400) monitors and controls the operation of the relay pump station (200), monitors the load measurement result—the result of measuring the load applied to the motor (203) installed in the storage tank (201) for pumping sewage, and can determine whether the relay pump station (200) is functioning normally using the load measurement result. For example, the remote monitoring controller (400) can determine that the relay pump station (200) is not functioning normally if the load applied to the motor (302) deviates from the normal range. As a specific example, in such a situation, the remote monitoring controller (400) can determine that the pipe (P) is clogged.

[0055] According to another embodiment, the remote monitoring controller (400) monitors and controls the operation of the relay pump station (200), monitors the water level measurement result measured by one or more water level measurement sensors (205, 207) installed in the storage tank (201) and the load measurement result measured by the load applied to the motor (203) installed in the storage tank (201) for pumping sewage, and can determine whether the relay pump station (200) is functioning normally by using both the water level measurement result and the load measurement result. For example, if the load applied to the motor (203) falls within the normal range but the sewage level does not fluctuate, the remote monitoring controller (400) can determine that the motor (203) is broken, the pipe (e.g., P in FIG. 2) is clogged, or the pipe (P) is damaged. For another example, when the load on the motor (203) is within the normal range and the sewage level does not fluctuate, if there are two motors (203), the remote monitoring controller (400) operates the other motor as well. Afterwards, if the sewage level drops, the remote monitoring controller (400) can determine that the first motor (203) has failed. Meanwhile, if the sewage level does not fluctuate even after operating both motors, the remote monitoring controller (400) can determine that the pipe (P) is clogged or damaged.

[0056] The remote monitoring controller (400) transmits the monitoring results (including water level measurement results) of the relay pump station (200) and the results of determining whether the relay pump station (200) is functioning normally to the central control unit (100).

[0057] When the remote monitoring controller (400) determines that the relay pump station (200) is not normal, it transmits information that can determine the location of the relay pump station (200) to a terminal - engineer terminal (500) - held by an engineer in charge of the relay pump station (200) that is determined to be not normal.

[0058] The remote monitoring controller (400) can determine whether the relay pump station (200) is functioning normally by referring to both the water level measurement result and the load measurement result. For example, if the load measurement result indicates that the load applied to the motor (203) is normal, and the water level measurement result indicates that the change in the water level of the sewage stored in the storage tank (201) is not normal, the remote monitoring controller (400) determines that the relay pump station (200) is not functioning normally.

[0059] As another example, if the sensing result of the contact-type water level measuring sensor (207) and the sensing result of the non-contact-type water level measuring sensor (205) are different from each other, the remote monitoring controller (400) can determine whether the contact-type water level measuring sensor (207) and the non-contact-type water level measuring sensor (205) are normal using the load measurement result.

[0060] For example, when the result measured by the contact water level measuring sensor (207) indicates that the water level is not changing, the result measured by the non-contact water level measuring sensor (205) indicates that the water level is changing, and the load measurement result indicates that the motor (203) is performing a pumping operation, the remote monitoring controller (400) determines that the contact water level measuring sensor (207) is not normal.

[0061] The remote monitoring controller (400) can operate in a setting mode or a monitoring mode. The setting mode is a mode that supports an administrator or engineer in setting the operation of the remote monitoring controller (400), and the monitoring mode is a mode in which the remote monitoring controller (400) monitors, determines whether there is an abnormality in the relay pumping station (200) based on the monitoring results, and calculates the accumulated sewage processing volume.

[0062] For example, the setting mode is a mode that supports setting at least one of a water level measurement setting, a motor (203) quantity setting, and a motor (203) operation setting. Here, the water level measurement setting is a selection of whether to use all different types of water level measurement sensors (205, 207) when different types of water level measurement sensors (205, 207) are installed in the storage tank (201) - sensor parallel use - or to use only one type among the different types of water level measurement sensors (205, 207) - sensor exclusive use -.

[0063] The motor (203) quantity setting is to set the number of pumps installed in the relay pump station (200).

[0064] When multiple motors (203) are installed in a relay pump station (200), such multiple motors (203) operate alternately, and the operation setting of the motors (203) is to set an alternating cycle.

[0065] The remote monitoring controller (400) may be equipped with a device such as a ‘DIP switch’ to support a setting mode. An administrator or engineer can perform a water level measurement setting, a motor (203) quantity setting, and a motor (203) operation setting by changing the position of the switch in the ‘DIP switch’. The remote monitoring controller (400) is configured to recognize the position of such a DIP switch (not shown) electrically, electronically, and / or mechanically, and performs a monitoring mode based on such settings.

[0066] When the setting mode is completed, the remote monitoring controller (400) operates in monitoring mode. In monitoring mode, as described above, monitoring operations, judgment operations, and calculation of the accumulated sewage throughput are performed. In monitoring mode, when the remote monitoring controller (400) receives setting information and engineer information of the relay pump station operating system from the central control unit (100), it stores and manages the data in a device capable of storing data.

[0067] According to one embodiment, the remote monitoring controller (400) may be configured to include a microprocessor (401), a memory device (403), an input / output interface (405), and a network interface (407) as illustrated in FIG. 3 for the operation described above. Although not illustrated, the remote monitoring controller (400) may further include a Global Positioning System (GPS) receiver. The Global Positioning System (GPS) receiver can receive signals transmitted from GPS satellites to determine its position relative to the satellites.

[0068] The microprocessor (401) executes programs to perform a configuration mode and a monitoring mode. The programs here may be stored inside the microprocessor (401) or in a memory device (403), and may be one or more programs for the operation of the operating system, the configuration mode, and the monitoring mode. The operating system (OS) may operatively connect other hardware, firmware, or application programs (e.g., management programs).

[0069] The network interface (407) is a module made of hardware for communicating with the outside, and may be, for example, a communication LAN card for short-range and / or long-range communication.

[0070] The memory device (403) is a recording medium that can record programs and be read by a computer, and may be, for example, volatile memory, permanent, virtual memory, HDD, or SSD, and may store setting information of the relay pump station operating system, engineer information, monitoring results, judgment results, accumulated sewage throughput, etc.

[0071] The input / output interface (405) may be hardware capable of receiving and displaying setting information from a user. For example, the input / output interface (405) may be a DIP switch or a liquid crystal display capable of displaying data. Additionally, the components described above are operatively connected to each other. Meanwhile, descriptions or drawings of the components mentioned above are described or illustrated to the extent necessary for the purpose of explaining the present invention.

[0072] FIG. 4 is a drawing for explaining a remote monitoring controller (400) according to one embodiment of the present invention.

[0073] Referring to FIG. 4, a remote monitoring controller (400) according to one embodiment of the present invention may include a judgment unit (402), a storage unit (404), an input / output unit (406), and a communication unit (408). Meanwhile, although not illustrated, the remote monitoring controller (400) may further include a location information acquisition unit (not illustrated) capable of acquiring location information of itself (400).

[0074] The judgment unit (402), storage unit (404), input / output unit (406), communication unit (408), and location information acquisition unit (not shown) represent functional blocks composed of hardware and software. That is, FIG. 3 describes the remote monitoring controller (400) in terms of hardware, and FIG. 4 describes the remote monitoring controller (400) in terms of function as an example, and it will be understood that the remote monitoring controller (400) of FIG. 3 and the remote monitoring controller (400) of FIG. 4 are the same device.

[0075] In FIG. 4, the judgment unit (402) monitors the water level measurement result—water level measurement result—measured by one or more water level measurement sensors (205, 207) installed in the storage tank (201) and the load measurement result—load measurement result—measured by the motor (203) installed in the storage tank (201) for pumping sewage, and determines whether the relay pumping station (200) is functioning normally by using both the water level measurement result and the load measurement result. The water level measurement sensors (205, 207) and the power meter are operatively connected to the judgment unit (402). For example, the remote monitoring controller (400) and the water level measurement sensors (205, 207) may be connected via wired or wireless connection so that the sensing result of the water level measurement sensors (205, 207) is provided to the judgment unit (402). The remote monitoring controller (400) and the power meter can be connected via wired or wireless connection so that the measurement results of the power meter are also provided to the judgment unit (402).

[0076] The judgment unit (402) determines whether the relay pump station (200) is normal by referring to both the water level measurement result and the load measurement result. For example, if the load measurement result indicates that the load applied to the motor (203) is normal, but the water level measurement result indicates that the change in the water level of the sewage stored in the storage tank (201) is not normal, the judgment unit (402) determines that the relay pump station (200) is not normal.

[0077] As another example, if the sensing result of the contact-type water level measuring sensor (207) and the sensing result of the non-contact-type water level measuring sensor (205) are different from each other, the judgment unit (402) can determine whether the contact-type water level measuring sensor (207) and the non-contact-type water level measuring sensor (205) are normal using the load measurement result.

[0078] For a specific example, when the result measured by the contact water level measuring sensor (207) indicates that the water level is not changing, the result measured by the non-contact water level measuring sensor (205) indicates that the water level is changing, and the load measurement result indicates that the motor (203) is performing a normal pumping operation, the judgment unit (402) determines that the contact water level measuring sensor (207) is not normal.

[0079] The judgment unit (402) performs operations in the monitoring mode. It monitors the relay pumping station (200), determines whether there is an abnormality in the relay pumping station (200) based on the monitoring results, and calculates the accumulated sewage treatment volume.

[0080] The communication unit (408) and the remote monitoring controller (400) transmit the monitoring results (including water level measurement results) of the relay pump station (200) and the results of determining whether the relay pump station (200) is functioning normally to the central control unit (100).

[0081] In addition, when the communication unit (408) determines by the judgment unit (402) that the relay pump station (200) is not normal, it transmits information that can identify the location of the relay pump station (200) to the terminal - engineer terminal (500) - held by the engineer in charge of the relay pump station (200) that is determined not normal. Meanwhile, the contact information of the engineer terminal (500) (e.g., a smartphone phone number) or the information that can identify the location of the relay pump station (200) may be stored in the storage unit (404).

[0082] The input / output unit (406) can receive commands or data from an engineer or manager. For example, the input / output unit (406) supports a user in inputting a setting mode. As described above, the input / output unit (406) may include an input device such as a DIP switch and an output device such as a liquid crystal display.

[0083] The input / output unit (406) performs operations in the setting mode. For example, the input / output unit (406) supports setting at least one of a water level measurement setting, a motor (203) quantity setting, and a motor (203) operation setting. For a detailed description of these settings, please refer to FIG. 3.

[0084] As described above, the input / output unit (406) may include components such as a 'DIP switch' to support the setting mode. The judgment unit (402) performs the operation according to the setting mode set through the input / output unit (406).

[0085] FIG. 6 is a diagram illustrating a method for operating a relay pumping station according to one embodiment, and illustrates an exemplary method for determining whether there is an abnormality in the motor, water level sensor, and piping of the relay pumping station (200) at the relay pumping station monitoring and control panel (300). In one embodiment, this method for determining the abnormality can be performed in a remote monitoring controller (400) within the relay pumping station monitoring and control panel (300), and, for example, can be performed in a judgment unit (402) of the remote monitoring controller (400).

[0086] In addition, the method of FIG. 6 assumes that one motor (203a or 203b) and one water level sensor (205 or 207) are installed in the relay pump station (200), but it is of course applicable even when two motors (203a, 203b) or two water level sensors (205, 207) are installed depending on the specific embodiment.

[0087] Referring to FIG. 6, first, the judgment unit (402) can determine whether the motor (203) is faulty in step (S110). For example, the judgment unit (402) can measure the power consumption of the motor (203) and determine that the motor (203) is faulty if the power consumption is higher or lower than a preset normal range.

[0088] If the motor (203) is faulty (S120_N), the judgment unit (402) can transmit the fact of the motor's failure and the location information of the corresponding relay pump station (200) to the central control unit (100) (S160). Alternatively, the judgment unit (402) may transmit the fact of the motor's failure and the location information of the relay pump station (200) to a terminal (engineer terminal (500)) held by an engineer in charge of the corresponding relay pump station.

[0089] If the motor (203) is determined to be normal (S120_Y), the judgment unit (402) determines whether the water level measuring sensor (205 or 207) is malfunctioning (S130). For example, the expected water level of sewage stored in the storage tank (201) can be calculated based on at least one of the power consumption, operating time, and accumulated sewage processing volume of the motor (203), and the expected water level calculated in this way can be compared with the water level measurement result of the water level measuring sensor to determine whether the water level measuring sensor is malfunctioning.

[0090] If the water level measuring sensor is faulty (S140_N), the judgment unit (402) can transmit the fact of the water level measuring sensor's failure and the location information of the corresponding relay pump station (200) to the central control unit (100) (S160), and alternatively, it can also transmit it to the terminal (50) of the engineer in charge of the corresponding relay pump station.

[0091] If the water level sensor determines that it is normal (S140_Y), the judgment unit (402) determines whether there is an abnormality in the pipe (Pa or Pb) (S150). That is, if steps (S110) through (S140) are performed and it is determined that both the motor and the water level sensor are normal, the presence or absence of an abnormality in the pipe (P) can be determined by periodically or non-periodically monitoring, for example, changes in the water level of the sewage stored in the storage tank (201) and / or the accumulated amount of sewage discharged through the pipe (P) at regular time intervals or at specific events. For example, the pipe (P) may become clogged with foreign matter, or in the case of winter, the pipe (P) may freeze.

[0092] If it is determined that there is an abnormality in the pipe (P) as a result of such periodic or non-periodic monitoring, the judgment unit (402) may transmit the fact of the abnormality in the pipe (P) and the location information of the corresponding relay pump station (200) to the central control unit (100) (S160), and alternatively, it may transmit it to the terminal (50) of the engineer in charge of the corresponding relay pump station.

[0093] FIG. 7 is a drawing illustrating a method of operating a relay pump station according to an alternative embodiment, illustrating an exemplary method of determining whether there is an abnormality in the motor, water level sensor, and piping of the relay pump station (200) at the relay pump station monitoring and control panel (300), and when compared with FIG. 6, FIG. 7 shows a method of determining whether there is an abnormality when two motors (203a, 203b) and two water level sensors (205, 207) are installed.

[0094] Referring to FIG. 7, the judgment unit (402) can determine whether the motor (203) is faulty in step (S210). Specifically, it can first determine whether the currently operating motor (one of 203a or 203b) (hereinafter simply referred to as the "first motor") is faulty, and at this time, for example, the power consumption of the first motor is measured, and if the power consumption is higher or lower than a preset normal range, it can be determined that the first motor is faulty (S211).

[0095] If the first motor is faulty (S212_N), the remote monitoring controller (400) operates the remaining motor (hereinafter referred to as the "second motor") (S213) and determines whether the second motor is faulty. For example, if a change in the sewage level of the storage tank (201) occurs when the second motor is operated (S214_Y), it can be determined that the second motor is normal and the first motor is faulty, and the fact of the first motor's failure and the location information of the corresponding relay pump station (200) can be transmitted to the central control unit (100) and / or the engineer's terminal (50) (S260).

[0096] As another example, when the second motor is operated (S213), the power consumption of the second motor is measured, and if the power consumption is higher or lower than a preset normal range, it is determined that the second motor is faulty. In this case, it is determined that both the first motor and the second motor are faulty, and in step (S260), the fact of the fault of the first motor and the second motor and the location information of the corresponding relay pump station can be transmitted to the central control unit (100) and / or the engineer's terminal (50) (S260).

[0097] If the first motor is normal (S212_Y) or if there is no change in the sewage level even after the second motor is operated (S214_N), it can be considered that there is an abnormality in the water level measuring sensor (205 or 207) or the piping (P), so the process proceeds to step (S230). That is, the judgment unit (402) determines whether the water level measuring sensor (205, 207) is faulty in step (S230). For example, the expected water level of sewage stored in the storage tank (201) can be calculated based on at least one of the power consumption, operating time, and accumulated sewage processing volume of the motor (203), and the expected water level calculated in this way can be compared with the water level measurement result of the water level measuring sensor to determine whether the water level measuring sensor is faulty. At this time, if the sensing result of the contact-type water level measuring sensor (207) and the sensing result of the non-contact-type water level measuring sensor (205) are different from each other, the normal status of the contact-type water level measuring sensor (207) and the non-contact-type water level measuring sensor (205) can be determined by comparing the calculated expected water level with each sensing result.

[0098] If either of the two water level measuring sensors fails (S240_N), the judgment unit (402) can transmit the fact of failure of the water level measuring sensor and the location information of the corresponding relay pump station (200) to the central control unit (100) and / or the engineer's terminal (50) (S160).

[0099] If it is determined that at least one of the two water level measuring sensors is normal (S240_Y), the judgment unit (402) can determine whether there is an abnormality in the pipe (P) (S250). That is, if steps (S210) to (S240) are performed and at least one motor and at least one water level measuring sensor are determined to be normal, in step (S250), the change in the water level of the sewage stored in the storage tank (201) and / or the accumulated amount of sewage discharged through the pipe (P) can be monitored periodically or non-periodically, for example, at a certain time interval or at a specific event, to determine whether there is an abnormality in the pipe (P).

[0100] If it is determined that there is an abnormality in the pipe (P) as a result of such periodic or non-periodic monitoring, the judgment unit (402) can transmit the fact of the abnormality in the pipe (P) and the location information of the corresponding relay pump station (200) to the central control unit (100) and / or the engineer's terminal (50) (S260).

[0101] Now, with reference to FIGS. 8 to 12, an exemplary system and method for managing a relay pump station monitoring and control panel (300) will be described.

[0102] FIG. 8 schematically illustrates a management system of a relay pump station monitoring and control panel (300) according to one embodiment. Referring to FIG. 8, the management system of a relay pump station monitoring and control panel according to one embodiment may include an access control system (110) and a locking device (310), and the access control system (110) and the locking device (310) are operationally connected to each other through a communication network. For example, the access control system (110) can control the locking and unlocking operations of the locking device (310) through a communication network.

[0103] The relay pump station monitoring and control panel (300) may be installed on the ground adjacent to each relay pump station (200) and may be a device having an appearance such as that shown in FIG. 9. In FIG. 9, various equipment such as a remote monitoring controller (400) is installed inside the device of the relay pump station monitoring and control panel (300), and a locking device (310) is installed on the opening and closing door so that an engineer can lock or open the opening and closing door by locking and unlocking the locking device (310).

[0104] FIG. 10 schematically illustrates an exemplary configuration of a locking device (310). Referring to FIG. 10, the locking device (310) may include a communication unit (311), a microcomputer (312), a display unit (313), a mechanical unit (314), and a power supply (315).

[0105] The communication unit (311) is configured to communicate with the access control system (110) via a wired and / or wireless communication network. That is, the communication unit (311) is configured to receive an unlock signal, a lock signal, and an access control phone number from the access control system (110) of the locking device (310).

[0106] When the communication unit (311) receives an access control phone number, the access control phone number is displayed by the display unit (313) in a form that can be visually seen by a person. The display unit (313) can display text so that the access control phone number can be visually seen by a person. When the communication unit (311) receives an access control phone number, the access control phone number is displayed on the display unit (313). For example, FIG. 11 illustrates an example of the display unit (313) displaying an access control phone number.

[0107] The mechanism (314) includes all parts necessary for locking or unlocking. That is, the mechanism (314) is configured to physically lock or open the door of the relay pump station monitoring control panel (300). The mechanism (314) can be implemented as a known digital door lock remote control system.

[0108] The power source (315) supplies the necessary power to each component of the locking device (310). The power source (315) may be implemented as a battery or configured to supply power to each component of the locking device (310) by receiving power from an external power grid.

[0109] The microcomputer (312) refers to a microprocessor computer and is configured to include a central processing unit (CPU), memory, ROM, input / output device, and circuits for the operation of each of these components. The microcomputer (312) performs a corresponding operation when the communication unit (311) receives data such as an unlock signal, a lock signal, and / or an access control phone number. For example, when the communication unit (311) receives an unlock signal, the microcomputer (312) controls the mechanism unit (314) to open the door, and when the communication unit (311) receives a lock signal, the microcomputer (312) controls the mechanism unit (314) to close the door. Additionally, when the communication unit (311) receives an access control phone number, the microcomputer (312) controls the display unit (313) to display the access control phone number.

[0110] Referring again to FIG. 8, an access control system (110) according to one embodiment of the present invention may be installed in a central control unit (100). However, in an alternative embodiment, the access control system (110) may be installed independently of the central control unit (100).

[0111] In one embodiment, the access control system (110) may include an access control server (101), a database (DB) storage device (103), and an IP-PBX (105). Here, the DB storage device (103) may include an authority DB that stores data of administrators or engineers who have the authority to access the relay pump station monitoring and control panel (300).

[0112] The access control system (110) controls the opening and closing of the locking device (310) of the relay pump station monitoring and control panel (300). The access control system (110) can store and manage the identification information (ID) of each locking device (310) and the most recently updated access control phone number by matching them.

[0113] When an access user (U1) calls the access management phone number displayed on the display (313) of the locking device (310), the access management system (110) checks whether the access user (U1) has the authority to access the relay pump station monitoring control panel (300) by referring to the caller ID of the access user (U1), and transmits an unlock signal to the locking device (310) only if the access user (U1) has the authority to access. Therefore, the access user (U1) can unlock the locking device (310) simply by calling the access management phone number displayed on the locking device (310) of the relay pump station monitoring control panel (300).

[0114] According to the present embodiment, a different access control phone number is assigned to the locking device (310) of each relay pump station monitoring and control panel (300) installed at each relay pump station (200), and by changing this access control phone number periodically or non-periodically, the person intending to enter must go to a location close to the locking device (310) and call the access control phone number displayed on the locking device (310).

[0115] As illustrated in FIG. 11, since the person entering (U1) can only see the access control phone number displayed on the display (313) of the locking device (310) by looking directly at it, the person who wishes to unlock the locking device (310) must approach close enough to be able to see the locking device (310) visually (i.e., to be able to see the text displayed on the display (313) visually), and this is to prevent the locking device (310) from being unlocked from a position far away from the locking device (310). In other words, this is to ensure that even an authorized person cannot unlock the locking device (310) unless they are in a position close to the locking device (310).

[0116] The access control system (110) stores and manages the phone numbers of people who can access the relay pump station monitoring and control panel (300) in the DB (103). When an access user (U1) who has the authority to access the relay pump station monitoring and control panel (300) calls the access control phone number displayed on the locking device (310), the access control system (110) can identify the caller ID (i.e., the access user's phone number) of the access user (U1). The access control system (110) can determine whether the access user has access authority by checking whether the caller ID of the access user (U1) is a number stored in the authority DB of the DB (103).

[0117] The access control system (110) assigns and manages an access control phone number to each locking device (310) of each relay pump station monitoring and control panel (300), and changes it periodically or non-periodically. When changing it periodically, it can be changed at preset time intervals, such as several hours or tens of hours. When changing it periodically, for example, the access control phone number can be changed whenever an accesser (U1) calls the access control phone number displayed on the display unit (313). The access control system (110) assigns access control phone numbers to each locking device (310) so that they are different and do not overlap.

[0118] FIG. 12 is a diagram illustrating a method of managing a relay pump station monitoring and control panel (300) according to one embodiment.

[0119] The access control system (110) periodically or non-periodically transmits an access control phone number to each locking device (310) of each relay pump station monitoring control panel (300) (S310), and the locking device (310) receives the access control phone number periodically or non-periodically, updates it, and displays it on the display unit (313) (S320). The access control system (110) can store and manage the most recently updated access control phone number for each locking device (310) in the DB (103). In addition, the access control system (110) stores and registers information such as phone numbers of entrants who can access each relay pump station monitoring control panel (300) in the DB (103) (S330).

[0120] A person (U1) who wishes to access the relay pump station monitoring and control panel (300) calls the access management phone number displayed on the display (313) of the locking device (310) (S340), and the access management system (110) identifies the phone number of the person (U1) through, for example, an IP-PBX (105), and can check whether the phone number of the person (U1) is a number stored in the authority DB of the DB (103) (S350).

[0121] The access control system (110) determines whether the person (U1) has access rights based on whether the person (U1) has called the phone number displayed on the display unit (313) of the lock device (310) and whether the person (U1)'s phone number is a number stored in the authority DB, and if it is determined that the person has access rights, the access control system (110) transmits a signal to unlock the lock device (310) (S360).

[0122] When the locking device (310) receives a release signal from the access control system (110), it controls the mechanism (314) to make the door of the locking device (310) openable (S370). Here, the 'state in which the door can be opened' means a state in which an entrant can open the door by hand. If the entrant does not open the door by hand for a predetermined period of time while the locking device (310) is in the 'state in which the door can be opened', the locking device (310) can control the mechanism (314) to close the door again.

[0123] As described above, those skilled in the art to which the present invention pertains will understand that various modifications and variations are possible from the description in this specification. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
