[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-201331 Summary of the Invention [Problem to be solved by the invention]

[0004] The maintenance operation system of Patent Document 1 does not address the impact of work to inspect the load connected to the power supply device.

[0005] Some power supplies are configured to issue an alarm when unusual operations occur, and in such cases, an alarm may be issued due to, for example, an inspection of a load, such as an emergency facility connected to the power supply, which may be mistakenly interpreted as a serious malfunction of the power supply.

[0006] In one aspect of the present invention, a method for monitoring a power supply is provided that provides notification regarding the status of the power supply. [Means for solving the problem]

[0007] A method for monitoring a power supply device includes a power supply device having a power receiving terminal, an output terminal, and a storage battery that supplies power to the output terminal when normal power is not supplied to the power receiving terminal, and the computer executes a process to acquire information regarding the power receiving state of the power receiving terminal and the discharge state of the storage battery from the power supply device, and to output a first notification if the acquired information indicates that the storage battery is discharging while receiving power at the power receiving terminal.

[Figure 8] FIG. 10 is an explanatory diagram illustrating the configuration of a power supply device monitoring system according to a third embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0010] [Embodiment 1] 1 is an explanatory diagram illustrating the configuration of a power supply device monitoring system 10. The power supply device monitoring system 10 is a system that remotely monitors power supply devices 30 installed in a business establishment 83 that consumes power. The power supply device monitoring system 10 includes an information processing device 20.

[0011] The power supply device 30 is a device that supplies power received by a power receiving facility 85 installed in a business 83 from a power plant 89 via a power transmission network to various loads 86. The loads 86 include a normal load 865 and an emergency load 866.

[0012] The normal load 865 is electrical equipment and devices that are used constantly, such as control equipment and communication equipment for the power receiving equipment 85. The normal load 865 also includes electrical equipment that is turned on and off on a daily basis, such as normal lighting equipment. The emergency load 866 is emergency equipment that operates during a power outage, such as evacuation guide lights and emergency lighting equipment. A monitoring sensor 87 that detects whether the emergency load 866 is operating is installed in the business establishment 83. Details of the monitoring sensor 87 will be described later.

[0013] In this embodiment, all of the loads 86 are devices that operate on DC. The power supply device 30 is a DC uninterruptible power supply that normally converts power received from a power receiving facility 85 into DC and supplies the DC power to the load 86, and when power is not supplied from the power receiving facility 85 due to a power outage or the like, supplies power to the load 86 from a built-in storage battery 33 (see FIG. 3). The configuration of the power supply device 30 will be described later.

[0014] Emergency equipment is inspected periodically to ensure it operates reliably during a power outage. This inspection involves turning on emergency equipment that is normally de-energized and checking that it is functioning properly, such as lighting up.

[0015] There are two methods for inspecting the emergency equipment. The first method is to put the power supply device 30 into a pseudo-power outage state. The second method is to forcibly operate the emergency load 866 using an inspection switch or the like.

[0016] When the inspection is performed using the first method, it is possible to reliably check the operation of the emergency load 866 in the event of a power outage. However, the inspection reduces the amount of electricity stored in the storage battery 33. If a power outage occurs before the storage battery 33 is fully charged after the inspection is completed, there is a risk that the emergency load 866 will not be able to operate for the specified time. Furthermore, there is a risk that the storage battery 33 will deteriorate due to the discharge and charge cycles.

[0017] By performing inspection using the second method, these risks can be avoided. However, because the power supply device 30 is made to operate in a manner different from normal, an alarm may be issued from the power supply device 30 to notify of an abnormality. In response to such an alarm, no action is required, such as checking the situation, ensuring safety, or carrying out recovery work. Details regarding the issuance of an alarm will be described later. The alarm is an example of a second notification in this embodiment.

[0018] At the business establishment 83, maintenance personnel working in a central monitoring room 84 are responsible for maintaining and managing various facilities such as power receiving equipment 85, power supply devices 30, and wiring equipment. When an alarm is issued from various facilities including the power supply devices 30, an alarm notification device installed in the central monitoring room 84 lights up and sounds.

[0019] Depending on the business establishment 83, the inspection of emergency equipment may be outsourced to an external inspection company by a department different from the central monitoring room 84. In large business establishments 83, there may be a large number of maintenance personnel working in the central monitoring room 84, and they may be divided into multiple departments. In such cases, the maintenance personnel who notice the alarm may not be aware that an inspection of emergency equipment is being carried out.

[0020] Normally, when maintenance personnel notice an alarm, they quickly take measures to ensure safety, etc. However, maintenance personnel who are unaware that an emergency equipment inspection is being carried out take time to realize that the alarm was triggered as a result of the emergency equipment inspection, and therefore end up wasting time on unnecessary tasks.

[0021] In addition to the above-mentioned alarm, power supply device monitoring system 10 of this embodiment sends a notification regarding the status of power supply device 30 to relevant parties such as maintenance personnel, for example to their smartphones. The sent notification is an example of the first notification of this embodiment. The first notification prevents an increase in the workload of maintenance personnel due to an alarm issued as a result of inspecting load 86.

[0022] Instead of a smartphone, an information device such as a general-purpose tablet, laptop, or wearable terminal may be used. Instead of a smartphone, dedicated hardware prepared for the power supply monitoring system 10 may be used. In the following explanation, an example will be taken in which the mobile device carried by each of the parties involved is a smartphone.

[0023] Operators at the remote monitoring center 82, engineers who rush from the remote monitoring center 82 to the business premises 83 in the event of an emergency, and maintenance personnel working in the central monitoring room 84 and other relevant parties use smartphones to receive notifications from the power supply monitoring system 10 and exchange information with each other.

[0024] The information processing device 20 is located in a remote monitoring center 82 that remotely monitors power supply devices 30 installed in multiple business locations 83. The information processing device 20 includes a control unit 21, a main memory device 22, an auxiliary memory device 23, a communication unit 24, a display unit 25, an input unit 26, and a bus. The control unit 21 is an arithmetic and control device that executes the program of this embodiment. The control unit 21 uses one or more central processing units (CPUs), graphics processing units (GPUs), multi-core CPUs, or the like. The control unit 21 is connected to each hardware unit that constitutes the information processing device 20 via the bus.

[0025] The main memory device 22 is a storage device such as an SRAM (Static Random Access Memory), a DRAM (Dynamic Random Access Memory), a flash memory, etc. The main memory device 22 temporarily stores information required during processing performed by the control unit 21 and programs currently being executed by the control unit 21.

[0026] The auxiliary storage device 23 is a storage device such as an SRAM, a flash memory, a hard disk, or a magnetic tape. The auxiliary storage device 23 stores programs to be executed by the control unit 21 and various data required for executing the programs. The communication unit 24 is an interface for communication between the information processing device 20 and the network N.

[0027] Display unit 25 is, for example, a liquid crystal display panel or an organic EL (electro-luminescence) panel, etc. Input unit 26 is, for example, a keyboard, a mouse, a pen tablet, etc. Display unit 25 and input unit 26 may be stacked to form a touch panel.

[0028] The information processing device 20 is a general-purpose personal computer, a tablet, a mainframe computer, a virtual machine running on a mainframe computer, or a quantum computer. The information processing device 20 may be configured with hardware such as multiple personal computers or mainframe computers that perform distributed processing. The information processing device 20 may be configured with a cloud computing system. The information processing device 20 may be configured with hardware such as multiple personal computers or mainframe computers that operate in cooperation with each other.

[0029] Fig. 2 is an explanatory diagram illustrating the normal state of the power supply device 30. As described above, the power supply device 30 of this embodiment is a DC uninterruptible power supply that supplies DC power to the load 86. The configuration of the power supply device 30 will be described using Fig. 2.

[0030] The power supply device 30 includes a rectifier 32, a storage battery 33, a sensor 34, a breaker 35, a power receiving terminal 311, a normal output terminal 315, an emergency output terminal 316, and a communication device 39. The sensor 34 includes an AC input sensor 341, a rectifier output sensor 342, and a storage battery output sensor 343. The breaker 35 includes an AC input breaker 351, a rectifier output breaker 352, a normal load input breaker 355, and an emergency load input breaker 356. For convenience in illustrating the state of the breaker 35, the breaker 35 is represented by the symbol for a single-pole, single-throw switch.

[0031] The communication device 39 is, for example, a network interface card. The communication device 39 is an interface that performs communication between the power supply device 30 and the network N.

[0032] The power receiving terminal 311 is connected to a commercial power supply via a power receiving facility 85. The normal output terminal 315 is connected to a normal load 865. The emergency output terminal 316 is connected to an emergency load 866.

[0033] Between the power receiving terminal 311 and the normal output terminal 315, an AC input breaker 351, a rectifier 32, a rectifier output breaker 352, and a normal load input breaker 355 are arranged in this order from the power receiving terminal 311 side. Between the rectifier output breaker 352 and the normal load input breaker 355, a battery connection point 361 to which the positive electrode of the storage battery 33 is connected is arranged.

[0034] A load branch point 365 disposed between the battery connection point 361 and the normal load input breaker 355 is connected to the emergency output terminal 316 via an emergency load input breaker 356. As shown in Fig. 2, the emergency load input breaker 356 is normally in the OFF state. In the event of a power outage, a control circuit (not shown) automatically switches the emergency load input breaker 356 to the ON state.

[0035] The power supply device 30 does not have to be equipped with the normal load input breaker 355 and the normal output terminal 315. To a power supply device 30 that does not have the normal load input breaker 355 and the normal output terminal 315, only the emergency load 866 is connected.

[0036] The AC input sensor 341 detects the state of power reception from the power receiving terminal 311, specifically, whether or not AC power is being input from the power receiving terminal 311. The AC input sensor 341 may measure the AC current and AC voltage between the power receiving terminal 311 and the AC input breaker 351.

[0037] The rectifier output sensor 342 measures the rectifier output current and rectifier output voltage output from the rectifier 32. The storage battery output sensor 343 measures the discharge state of the storage battery 33, specifically, the storage battery output current and storage battery output voltage output from the storage battery 33. Detailed wiring of each sensor 34 is not shown in the drawings.

[0038] When the storage battery output current flows from the positive electrode of the storage battery 33 toward the storage battery connection point 361, the operating state of the storage battery 33 is discharging. When the storage battery output current flows from the storage battery connection point 361 toward the positive electrode of the storage battery 33, the operating state of the storage battery 33 is charging. Therefore, the control unit 21 can obtain the operating state of the storage battery 33 by obtaining the output from the storage battery output sensor 343.

[0039] The data measured by each sensor 34 is transmitted to the information processing device 20 via the communication device 39 and the network N. Each sensor 34 and the communication device 39 are connected by wire or short-range wireless communication.

[0040] Each sensor 34 may be a so-called IoT device having a communication function, and each may transmit data directly to the information processing device 20 via the network N. For example, TCP / IP (Transmission Control Protocol / Internet Protocol) may be used as the communication protocol between the sensor 34 and the information processing device 20.

[0041] The breaker 35 has three states: on state, off state, and trip state. The on state is a state in which current passes through. The off state is a state in which current is cut off. The breaker 35 is equipped with a switch that the user uses to switch between the on state and the off state. The trip state is a state in which the breaker 35 automatically switches to cut off the current when an excessive current flows through the breaker 35 in the on state. In the following description, the automatic switching of the breaker 35 to the trip state may be referred to as tripping.

[0042] After tripping, the breaker 35 is in a state between the on and off states. The tripped breaker 35 remains in the tripped state until the user manually switches it to the on or off state. The user cannot switch the breaker 35 to the tripped state through normal operation.

[0043] In Fig. 2, AC input breaker 351, rectifier output breaker 352, and normal load input breaker 355 are all in the ON state. As described above, emergency load input breaker 356 is in the OFF state. AC power is applied from power receiving equipment 85 to power receiving terminal 311. The AC power is converted to DC power by rectifier 32. The DC power is applied to normal load 865 via normal output terminal 315. As a result, current flows from power receiving terminal 311 to normal output terminal 315, as shown by the thick arrow in Fig. 2.

[0044] 2, a relatively small rectifier 32 is selected that is large enough to cause an overload condition when power is supplied to both the normal load 865 and the emergency load 866. By using such a rectifier 32, it is possible to reduce the size and cost of the power supply device 30.

[0045] If the storage battery 33 is not fully charged, a charging current also flows to the storage battery 33 via the storage battery connection point 361. If the storage battery 33 is fully charged, no current flows between the storage battery 33 and the storage battery connection point 361. Since the emergency load input breaker 356 is in the OFF state, no current flows to the emergency load 866 either.

[0046] 3 is an explanatory diagram illustrating the state of the power supply device 30 during a power outage. For example, if a problem occurs in the power distribution equipment between the power plant 89 and the power receiving equipment 85, or if a problem occurs in the power receiving equipment 85, a power outage occurs and AC power is not supplied to the power receiving terminal 311. As described above, if a power outage occurs, the emergency load input breaker 356 is automatically switched to the ON state by a control circuit (not shown).

[0047] In the event of a power outage, power is automatically supplied from the storage battery 33 to the normal output terminal 315 and the emergency output terminal 316 via the storage battery connection point 361. The power supply path during a power outage is indicated by a thick arrow. When the power outage is resolved, a control circuit (not shown) automatically switches the emergency load input breaker 356 to the OFF state. The power supply path automatically returns to the state described using Figure 2. Furthermore, charging of the storage battery 33 is also performed.

[0048] The capacity of the storage battery 33 is set so that even if the power outage is prolonged, there is sufficient margin for evacuation guidance, etc. Maintenance personnel and the person in charge of managing the regular load 865 may safely stop the regular load 865 according to a predetermined work procedure, or may switch the regular load 865 to a power saving mode, thereby extending the operable time of the emergency load 866.

[0049] 1, the explanation will be continued. The control unit 21 obtains information regarding whether the emergency load 866 is operating or not via the monitoring sensor 87. The monitoring sensor 87 is, for example, a power consumption sensor attached to the emergency load 866. If the emergency load 866 is an evacuation guide light or an emergency lighting facility, the monitoring sensor 87 may be a brightness sensor arranged near the emergency load 866.

[0050] The monitoring sensor 87 may be a sensor that detects whether or not power is being supplied from the emergency output terminal 316 to the emergency load 866. The monitoring sensor 87 may be an ammeter that measures the current flowing from the emergency output terminal 316 to the emergency load 866. The monitoring sensor 87 transmits data to the information processing device 20 via the network N, similar to the sensor 34 described above.

[0051] FIG. 4 is a state transition diagram illustrating the operation of the power supply device 30. In the following description, the state of the power supply device 30 during normal operation described using FIG. 2 will be referred to as the normal power supply mode, and the state of the power supply device 30 during a power outage described using FIG. 3 will be referred to as the power outage power supply mode. When a power outage occurs, the power supply device 30 transitions from the normal power supply mode to the power outage power supply mode. When the power outage ends and power is restored, the power supply device 30 transitions from the power outage power supply mode to the normal power supply mode.

[0052] The dashed line indicates the state transition when the emergency load 866 is inspected using the second method described above. The inspection begins when a maintenance person operates an inspection switch or the like to forcibly operate the emergency load 866. The emergency load 866 operates in addition to the normal load 865. The maintenance person inspects whether each emergency load 866 is operating correctly.

[0053] As described above, a relatively small rectifier 32 is selected for the rectifier 32, so that it will be in an overload state if it supplies power to both the normal load 865 and the emergency load 866. When the rectifier 32 is in an overload state, the power supply device 30 transitions to an overload power supply mode, which will be described later. When inspection is completed and the maintenance personnel stops the emergency load 866, the power supply device 30 transitions to the normal power supply mode.

[0054] When inspecting emergency load 866 using the first method described above, that is, the method of putting power supply device 30 into a pseudo-power outage state, for example, maintenance personnel manually turn off both or either one of AC input breaker 351 and rectifier output breaker 352. The maintenance personnel may also disconnect power receiving equipment 85 from power receiving terminal 311.

[0055] Since the power supply from the rectifier 32 is stopped, power is supplied to the normal load 865 and the emergency load 866 from the storage battery 33, similar to the power supply mode during a power outage described using Fig. 3. Maintenance personnel check whether each emergency load 866 is operating correctly.

[0056] 5 is an explanatory diagram illustrating the state of the power supply device 30 during inspection using the second method. The emergency load input breaker 356 is manually switched to the ON state. Power is supplied to both the normal load 865 and the emergency load 866. To prevent the rectifier 32 from being overloaded, the storage battery 33 supplies the shortfall in power.

[0057] 5, current flows from both the rectifier 32 and the storage battery 33 to both the normal load 865 and the emergency load 866. Therefore, the rectifier output sensor 342 detects that DC power is being output from the rectifier 32, and the storage battery output sensor 343 detects that the storage battery 33 is being discharged.

[0058] The state of the power supply device 30 is different from the normal power supply mode described using Fig. 2 and the power failure power supply mode described using Fig. 3. Therefore, the power supply device 30 issues an alarm indicating that an abnormal discharge has occurred in the power supply device 30. The alarm is transmitted by wire from an alarm issuing device (not shown) to the central monitoring room 84, and causes an alarm notification device installed in the central monitoring room 84 to light up and sound.

[0059] The alarm may be notified to maintenance personnel or the like by any means, such as an in-house announcement, SMS (Short Message Service), email, a call to a smartphone using an automated voice, or a pop-up notification on the smartphone screen. It is desirable that the smartphone is set to vibrate or sound when it receives a notification to alert the maintenance personnel or the like.

[0060] For example, if a regular load 865 in use breaks down and a short circuit occurs, the current flowing through the regular load 865 increases, causing the rectifier 32 to enter an overload state, and the shortage of power is supplied from the storage battery 33. The same applies if a regular load 865 is added without confirmation by the central monitoring room 84.

[0061] If such a situation occurs, maintenance personnel must quickly disconnect the problematic regular load 865 from power supply device 30 and take measures to restore the system to normal. Therefore, the alarm indicating that abnormal discharge has occurred in power supply device 30 is necessary for the safe operation of business establishment 83, and it is not appropriate to stop issuing this alarm.

[0062] In view of the above circumstances, the control unit 21 of this embodiment transmits a first notification via a smartphone to relevant parties who are to receive the alarm when the rectifier 32 enters an overload state due to inspection of the emergency load 866. The first notification includes information that the alarm issued by the power supply device 30 is due to inspection of the emergency load 866, or that no abnormality has occurred in the power supply device 30.

[0063] As described above, the power supply device monitoring system 10 prevents an increase in the workload of maintenance personnel due to an alarm issued by the power supply device 30 resulting from inspection work on the emergency load 866.

[0064] Fig. 6 is a flowchart illustrating the flow of program processing. The flowchart in Fig. 6 is a flowchart of a monitoring program for power supply device 30 that is started by control unit 21 when storage battery output sensor 343 detects that the storage battery 33 is discharging.

[0065] The control unit 21 may start the program shown in Fig. 7 when the discharge time from the storage battery 33 exceeds a predetermined threshold, such as several minutes. The control unit 21 may start the program shown in Fig. 7 when an alarm is issued from the power supply device 30.

[0066] The control unit 21 detects whether AC power is being received from the power receiving terminal 311 based on data received from the AC input sensor 341 (step S501). If it is determined that power is not being received (NO in step S501), the control unit 21 notifies relevant parties via their smartphones that a power outage is occurring (step S502). Thereafter, the control unit 21 ends the process.

[0067] Note that if there is another means for the maintenance personnel to know of the occurrence of a power outage other than the power supply device monitoring system 10, the control unit 21 may end the process without executing step S501. In the event of an emergency such as a power outage, the maintenance personnel can focus on urgently required tasks by limiting the notifications sent to relevant parties from the power supply device monitoring system 10 via smartphones to the bare minimum.

[0068] If it is determined that power is being received (YES in step S501), the control unit 21 determines whether the emergency load 866 is operating based on the data received from the monitoring sensor 87 (step S503). If it is determined that the emergency load 866 is operating (YES in step S503), the control unit 21 transmits a first notification to the relevant person via the smartphone indicating that the alarm issued from the power supply device 30 is due to an inspection of the emergency load 866 or that no abnormality has occurred in the power supply device 30 (step S504). After step S504 is completed, or if it is determined that the emergency load 866 is not operating (NO in step S503), the control unit 21 ends the process.

[0069] In step S501, the control unit 21 may determine whether or not power is being output from the rectifier 32 based on information received from the rectifier output sensor 342. If it is determined that power is being output from the rectifier 32, the control unit 21 proceeds to step S503, and if it is determined that power is not being output from the rectifier 32, the control unit 21 proceeds to step S502.

[0070] [Embodiment 2] This embodiment relates to a power supply device monitoring system 10 that uses a power supply device 30 that does not issue an alarm when current flows from both a rectifier 32 and a storage battery 33 to both a normal load 865 and an emergency load 866, as explained using Fig. 5. Explanations of parts common to the first embodiment will be omitted.

[0071] Fig. 7 is a flowchart illustrating the flow of processing of the program according to embodiment 2. The flowchart in Fig. 7 relates to a monitoring program for power supply device 30, which is activated by control unit 21 when storage battery output sensor 343 detects that the storage battery 33 is discharging.

[0072] The processing from step S501 to step S504 is the same as the processing of the program in embodiment 1 described using Fig. 6, and therefore description thereof will be omitted. If it is determined that the emergency load 866 is not operating (NO in step S503), the control unit 21 transmits a second notification to the relevant person via the smartphone indicating that an abnormal discharge has occurred in the power supply device 30 (step S505). Thereafter, the control unit 21 ends the processing.

[0073] According to this embodiment, it is possible to provide a power supply device monitoring system 10 that transmits the first notification instead of the power supply device 30.

[0074] [Embodiment 3] 8 is an explanatory diagram illustrating the configuration of a power supply device monitoring system 10 according to a third embodiment. This embodiment relates to a form in which the power supply device monitoring system 10 is realized by combining and operating a general-purpose computer 90 and a program 97. Explanations of parts common to the first embodiment will be omitted.

[0075] The computer 90 includes a reading unit 29 in addition to the control unit 21, main memory unit 22, auxiliary memory unit 23, communication unit 24, display unit 25, input unit 26 and bus.

[0076] The program 97 is recorded on a portable recording medium 96. The control unit 21 reads the program 97 via the reading unit 29 and stores it in the auxiliary storage device 23. The control unit 21 may also read the program 97 stored in a semiconductor memory 98, such as a flash memory, implemented in the computer 90. Furthermore, the control unit 21 may download the program 97 from another computer (not shown) connected via the communication unit 24 and a network (not shown) and store it in the auxiliary storage device 23. The program 97 is installed as a control program for the computer 90, and is loaded into the main storage device 22 and executed.

[0077] The power supply monitoring system 10 described in the first embodiment is realized in this manner. The program 97 in this embodiment is an example of a program product. The computer program can be deployed to run on a single computer, or on multiple computers located at one site, or distributed across multiple sites and interconnected by a communications network.
