Description

  The present invention relates to a control device that controls power recovery, a power recovery control system, and a program.

  An emergency earthquake bulletin has been provided by the Japan Meteorological Agency since 2007. The Earthquake Early Warning reports the expected seismic intensity and expected arrival time in each location as early as possible based on information detected by a seismometer near the epicenter. The earthquake early warning is not only broadcast on television and radio, but is also notified to the user of the desired mobile phone using the broadcast function of the mobile phone. It is also possible to obtain information related to the earthquake early warning via the Internet.

  Emergency earthquake alerts are useful for preparing for earthquakes and for taking measures to prevent secondary disasters such as fires. However, even if you see an earthquake early warning, you may not be able to take all the steps you need to do before the earthquake arrives. For example, if the wiring breaker is removed immediately when an earthquake is detected, evacuation becomes difficult at night.

  In Patent Document 1, even if an earthquake is detected, an electric circuit is secured to help evacuate until the electric power company stops transmission, and if the electric power company re-transmits power (restores power) after power transmission is stopped (power failure), immediately A technique for tripping a circuit breaker for wiring is disclosed.

  The current-carrying prevention device described in Patent Document 1 includes a seismic sensor, a storage means for storing the state when the seismic sensor senses an earthquake and the power circuit is interrupted, and the power circuit is restored. When the storage means is storing the above state, it comprises a trip circuit that outputs a trip signal to the circuit breaker.

Japanese Patent Application Laid-Open No. 9-289831

  However, in the technique described in Patent Document 1, in order to operate an electric device, it is necessary for the user to operate the wiring breaker to release the interruption of the power supply. Therefore, there is a problem that it takes time for the user and reduces the convenience for the user.

  In addition, when the user goes out when a power failure occurs, or when the user does not notice that the user has recovered from the power failure, the user cannot operate the circuit breaker. For this reason, the technique described in Patent Document 1 has a problem in that all electric devices may remain stopped for a long time, even though power is restored, thereby reducing user convenience.

  The present invention has been made in view of such circumstances. When a power failure due to a disaster occurs and the power failure ends, the convenience of the user can be improved while ensuring safety. An object is to provide a possible control device.

The control device according to the present invention includes:
Branch path information storage means for storing branch path information indicating whether or not the branch path to which the electrical device can be connected may be conducted to the power source path at the time of power recovery;
Cause flag information storage means for storing cause flag information indicating whether the cause of the power failure is a disaster;
A power path sensor for generating a signal indicating a state of energization in the power path;
Based on a signal generated by the power supply path sensor, power recovery determination means for determining whether power has been recovered,
Even if it is determined that the power has been restored by the power restoration judging means, and the cause flag information indicates that the cause of the power failure is a disaster, the branch path information may be connected to the power supply path at the time of power restoration. When indicated as good, the branch path is connected to the power supply path, and when the branch path information indicates that the power supply path should not be connected when power is restored, the branch path is not connected to the power supply path. Power recovery control means for controlling

  According to the present invention, when a power failure occurs due to a disaster and the power is restored after that, when the branch information indicates that the power path may be conducted at the time of power restoration, the branch path is conducted to the power path. . Thereby, after power recovery, when an electrical device that is safe to operate is connected to the branch path, the branch path can be conducted to the power source path to operate the electrical device.

  Further, according to the present invention, when a power failure occurs due to a disaster and the power is restored after that, when the branch information indicates that the power path should not be connected when the power is restored, the branch path is connected to the power path. Do not conduct. As a result, electric devices other than those that are safe to operate even after power recovery can be kept stopped.

  As described above, according to the present invention, it is possible to operate only a safe electrical device after power recovery even if it is operated. Therefore, after a power failure due to a disaster occurs, when the power failure ends, it is possible to improve convenience for the user while ensuring safety.

The power recovery control system 1 is a system installed in a building such as a house or an office building, and controls power supply to an energization path in the building when power is recovered. The power recovery means that the power supply is restored after the power supply from the power supply is stopped (power failure).

  As shown in the figure, the power recovery control system 1 includes a distribution board 2 and a control device 3.

The third electric device 7 is a lamp as a notification means for notifying the user of power recovery.

  The distribution board 2 includes a main breaker 15, a first branch breaker 16, a second branch breaker 17, a third branch breaker 18, and a breaker control unit 19. The main breaker 15 is electrically connected to the power supply path 11, and the first to third branch breakers 16 to 18 are electrically connected to the first to third branch paths 12 to 14, respectively. The main breaker 15 and each of the first to third branch breakers 16 to 18 are electrically connected inside the distribution board 2 via the first to third connection paths 20 to 22 that are electrically disconnected. doing.

  Each of the breakers 15 to 18 is connected to the power supply path 11, the branch paths 12 to 14, or the connection paths 20 to 22 connected to the breakers 15 to 18 under the control of the breaker control unit 19. (State) switching mechanism.

  Specifically, in the case of the main breaker 15, between the power supply path 11 and all the connection paths 20 to 22, an electrically connected state (connected state) and an electrically disconnected state (blocked state) Can be switched. In each case of the first to third branch breakers 16 to 18, the connection state and the cutoff state are respectively set between the first to third connection paths 20 to 22 and the first to third branch paths 12 to 14. Can be switched.

  It is as follows when the conduction | electrical_connection state between the power supply path 11 and the 1st-3rd branch paths 12-14 is arranged according to the state of each breaker 15-18.

  When the main breaker 15 is in the cut-off state, all of the power supply path 11 and the first to third branch paths 12 to 14 are not conductive (electrically connected). When the main breaker 15 is in the connected state, and when the first branch breaker 16 is in the connected state, the power supply path 11 and the first branch path 12 are electrically connected, and the first branch breaker 16 is in the disconnected state The power supply path 11 and the first branch path 12 do not conduct. When main trunk breaker 15 is in a connected state, when second branch breaker 17 is in a connected state, power supply path 11 and second branch path 13 are conducted, and second branch breaker 17 is in a disconnected state. The power supply path 11 and the second branch path 13 are not electrically connected. When main trunk breaker 15 is in a connected state, when third branch breaker 18 is in a connected state, power supply path 11 and third branch path 14 are electrically connected, and third branch breaker 18 is in a disconnected state. The power supply path 11 and the third branch path 14 are not electrically connected.

The storage unit 32 storing the device information 35 corresponds to a device information storage unit. The storage unit 32 storing the branch path information 36 corresponds to a branch path information storage unit. The storage unit 32 storing the normal continuity information 37 corresponds to the sympathetic continuity information storage unit.

  The cause flag information 34 is information indicating a state of a flag (cause flag) indicating whether or not the cause of the power failure is an earthquake. In the present embodiment, “1” is set in the cause flag when the cause of the power failure is an earthquake, and “0” is set in the cause flag when the cause of the power failure is not an earthquake.

In the present embodiment, for example, it is not possible when the electric device generates heat, and it is possible when the heat is not generated.

  The term “generates heat” as used herein means that a fire may be caused when an electrical device is activated, such as when the combustible material scattered or dropped by an earthquake comes close to the electrical device, and the combustible material is burned. It generates a high degree of heat. For example, electric stoves, dryers, and the like are electric devices that generate heat, and refrigerators, lamps, and the like are electric devices that do not generate heat.

  The device information 35 shown in FIG. 3 indicates that for an electrical device that generates a harmonic of N1 (Hz), since the electrical device generates heat, it should not be allowed to conduct at the time of power recovery (impossible). . In addition, the device information 35 shown in the figure may be turned on when power is restored because the electrical device that generates harmonics of N2 (Hz) does not generate heat. It shows that.

  The branch path information 36 is information indicating whether or not each of the first to third branch paths 12 to 14 may be brought into conduction with the power path 11 at the time of power recovery.

The conduction permission / denial information 41 is information indicating whether or not to permit conduction between the power supply path 11 and each of the branch paths 12 to 14 after power is restored.

  The normal conduction information 37 is information indicating the state of each of the branch breakers 16 to 18 before a power failure occurs, that is, during normal times. Since the main breaker 15 is normally connected, the normal conduction information 37 is also information indicating whether or not each of the branch paths 12 to 14 is normally connected to the power supply path 11.

  The normal conduction information 37 according to the present embodiment includes breaker ID information 42 and state information 43, as shown in FIG. In the normal conduction information 37, the breaker ID information 42 and the state information 43 are associated with each of the first to third branch breakers 16-18.

The state information 43 is information indicating the states of the branch breakers 15 to 17 at the normal time. The normal conduction information 37 shown in FIG. 5 indicates that all of the first to third branch breakers 16 to 18 are in the connected state at the normal time.

  Note that the branch breakers to be controlled by the control device 3 may be the branch breakers 16 to 18 that are normally connected.

  The processing / control unit 33a includes a processing unit that executes various types of processing and a control unit that controls each unit included in the control device 3, and includes one or a plurality of processors. The processing / control unit 33a includes functions 44 to 71 as shown in FIGS. The function provided in the control unit 33 is realized by appropriately combining the function of the processor itself constituting the control unit 33 and the function provided in the processor by executing a software program (not shown) held in the storage unit 32. The

  The earthquake prediction determination unit 44 determines whether an earthquake at the installation location of the power recovery control system 1 is predicted based on the earthquake information acquired by the communication I / F unit 28. Specifically, when the communication I / F unit 28 acquires earthquake information, the earthquake prediction determination unit 44 acquires and analyzes it. As a result of the analysis, when the installation location is included in the predicted earthquake area, the earthquake prediction determination unit 44 determines that an earthquake at the installation location is predicted.

  When the cause flag setting unit 45a determines that an earthquake at the installation location is predicted and it is determined that a power failure has occurred, the cause flag setting unit 45a determines the elapsed time from a predetermined time after the communication I / F unit 28 acquires the earthquake information. Based on this, the cause flag information 34 is updated so that the cause flag is set to “1”.

  As shown in FIG. 7, the cause flag setting unit 45 a includes a flag setting unit 46 a, a timer unit 47 a, a progress determination unit 48 a, and a flag clear unit 49.

  The flag setting unit 46a updates the cause flag information 34 so that the cause flag is set to “1” when the earthquake prediction determination unit 44 determines that an earthquake at the installation location is predicted.

  When the communication I / F unit 28 acquires earthquake information, the time measuring unit 47a measures an elapsed time from a time point that is appropriately determined thereafter.

  The progress determination unit 48a determines whether or not the elapsed time measured by the time measuring unit 47a exceeds the threshold value T1. The threshold value T1 is set in advance and held in the storage unit 32.

  The flag clear unit 49 updates the cause flag information 34 so that the cause flag is set to “0”. The flag clear unit 49 according to the present embodiment updates the cause flag information 34 so that the cause flag is set to “0” when it is determined that the elapsed time measured by the time measuring unit 47a exceeds the threshold value T1. To do.

  The branch path information update unit 50 updates the branch path information 36 based on the signal acquired from the branch path sensor 31. As shown in FIG. 8, the branch path information update unit 50 includes a signal acquisition unit 51, an operation determination unit 52, a frequency identification unit 53, an extraction unit 54, a device energization determination unit 55, and a branch path information generation unit. 56 and a storage unit 57.

  The signal acquisition unit 51 acquires a signal indicating the energization state of each of the branch paths 12 to 14 from the branch path sensor 31.

  The operation determination unit 52 is based on the signal acquired by the signal acquisition unit 51, and whether the first to third electric devices 5 to 7 connected to the first to third branch paths 12 to 14 are operating. Judge whether or not. The operation determination unit 52 determines each of the first to third branch paths 12 to 14 and generates information indicating each determination result.

  Specifically, for example, when determining the first branch path 12, the operation determination unit 52 determines whether the first electricity connected to the first branch path 12 when a current of a certain level or more flows through the first branch path 12. It is determined that the device 5 is operating. The operation determination unit 52 indicates that the first electrical device 5 connected to the first branch path 12 is operating when the current does not flow through the first branch path 12 or when the flowing current is less than a certain level. Judge that it is not. That is, in order to determine that the first electric device 5 is not operating, the first electric device 5 is connected to the first branch path 12 in addition to the case where the first electric device 5 is connected to the first branch path 12 but is not operating. The case where it is not done is also included. The operation determination unit 52 similarly determines the second and third branch paths 13 and 14.

  The frequency specifying unit 53 specifies the harmonic frequency in each of the branch paths 12 to 14 to which the first to third electric devices 5 to 7 determined to be operating by the operation determining unit 52 are connected. The frequency specifying unit 53 acquires and analyzes the signal acquired from the branch path sensor 31, thereby specifying the harmonic frequency in each of the branch paths 12 to 14.

  The extracting unit 54 refers to the device information 35 and extracts the device energization availability information 39 associated with the frequency information 38 when there is frequency information 38 indicating the frequency specified by the frequency specifying unit 53.

  The device energization determination unit 55 determines the frequency indicated by the frequency information 38 associated with the device energization availability information 39 based on the device energization availability information 39 extracted by the extraction unit 54. ˜14, it is determined whether or not the electric devices 5-7 connected to the branch paths 12-14 may be energized.

  Specifically, when the device energization availability information 39 extracted by the extraction unit 54 indicates that energization is not possible, the device energization determination unit 55 displays the frequency indicated by the frequency information 38 associated with the device energization availability information 39 as a frequency specifying unit. It is determined that energization is impossible for the branch path identified by 53. In addition, when the device energization availability information 39 extracted by the extraction unit 54 indicates that energization is possible, the device energization determination unit 55 indicates the frequency indicated by the frequency information 38 associated with the device energization availability information 39. It is determined that energization is possible for the identified branch path.

  The branch path information generation unit 56 acquires information indicating the determination result of the device energization determination unit 55, and generates the branch path information 36 based on the acquired information.

  Specifically, the branch path information generation unit 56 applies the branch paths 12 to 14 to which the electrical devices 5 to 7 are determined to be energized by the device energization determination unit 55 when the power is restored. The continuity permission / inhibition information 41 indicating that continuity is permitted (permission) is generated. The branch path information generating unit 56 generates conduction permission / denial information 41 indicating that the other branch paths 12 to 14 should not be conducted at power recovery (not permitted). Then, the branch path information generation unit 56 generates the branch path information 36 in which the generated conduction permission / rejection information 41 is associated with the branch path ID information 40 of the corresponding branch paths 12 to 14.

  The storage unit 57 acquires the branch path information 36 generated by the branch path information generation unit 56 and stores the acquired branch path information 36 in the storage unit 32.

Returning to FIG.
The power failure determination unit 58 acquires a signal generated by the power supply path sensor 30 and determines whether or not a power failure has occurred based on the signal. For example, the power failure determination unit 58 calculates the power supplied from the power supply path 11 based on a signal from the power supply path sensor 30. The power failure determination unit 58 determines that a power failure has occurred when the calculated power is less than the threshold, and determines that a power failure has not occurred when the calculated power is equal to or greater than the threshold.

  The power supply control unit 59 switches the power supply of the control device 3 from the power supply path 11 to the standby power supply 29 when the power failure determination unit 58 determines that a power failure has occurred.

  When the power recovery preparation unit 60 determines that a power failure has occurred and the cause flag indicated by the cause flag information 34 is “1”, the breaker control is performed so that the main breaker 15 is turned off. A signal is transmitted to the unit 19 via the communication line 24. As a result, the main breaker 15 is controlled to be cut off via the breaker control unit 19. That is, the power recovery preparation unit 60 controls the first to third branch paths 12 to 14 not to be brought into conduction with the power supply path 11 through the breaker control unit 19.

  The power recovery determination unit 61 determines whether power has been recovered based on a signal acquired from the power supply path sensor 30. For example, when the power recovery determination unit 61 acquires a signal indicating the energization state of the power supply path 11 from the power supply path sensor 30 after the power failure determination unit 58 determines that a power failure has occurred, The power supplied from the path 11 is calculated. The power recovery determination unit 61 determines that power has been recovered when the calculated power is equal to or greater than the threshold, and determines that power has not been recovered when the calculated power is less than the threshold.

  The power recovery control unit 62 controls energization of each of the branch paths 12 to 14 at the time of power recovery. As shown in FIG. 6, the power recovery control unit 62 includes a mode determination unit 63, a normal mode unit 64, and an earthquake mode unit 65.

  The mode determination unit 63 refers to the cause flag information 34 at the time of power recovery, and determines the normal mode when the cause flag is “0”, and determines the earthquake mode when the cause flag is “1”.

  The normal mode unit 64 controls the states of the breakers 15 to 18 in the normal mode when the mode determination unit 63 determines the normal mode. Specifically, the normal mode unit 64 sets the main breaker 15 in the connected state when the mode determination unit 63 determines that the normal mode is set. At the same time, the normal mode unit 64 refers to the normal conduction information 37 and puts the branch breakers 16 to 18 that are normally in a conduction state into a connected state.

  The earthquake mode unit 65 controls the state of each of the breakers 15 to 18 in the earthquake mode, that is, to safely energize the branch paths 12 to 14 when the mode determination unit 63 determines that the mode is the earthquake mode. To do.

  As shown in FIG. 9, the earthquake mode unit 65 includes a full block unit 66, a main breaker connection unit 67, a notification control unit 68, a presence / absence determination unit 69, a partial connection (partial recovery) unit 70, and a full connection. (Total recovery) unit 71.

  All blocking unit 66 transmits a signal to breaker control unit 19 via communication line 24 so that all of first to third branch breakers 16 to 18 are blocked. As a result, the entire blocking unit 66 controls the first to third branch breakers 16 to 18 to be in a blocking state via the breaker control unit 19. In other words, the total blocking unit 66 controls the first to third branch paths 12 to 14 not to conduct to the power supply path 11 via the breaker control unit 19.

  The main breaker connection unit 67 transmits a signal to the breaker control unit 19 via the communication line 24 so that the main breaker 15 is connected. Thus, the main breaker connection unit 67 controls the main breaker 15 to be in a connected state via the breaker control unit 19. In other words, the main breaker connection unit 67 controls the main breaker 15 via the breaker control unit 19 to release the control for not conducting all of the first to third branch paths 12 to 14 to the power supply path 11 at once. To control. Accordingly, it is possible to control so that all of the first to third connection paths 20 to 22 are collectively conducted to the power supply path 11.

  The notification control unit 68 controls the lamp 7 to be lit in order to notify the user that power has been restored. At this time, it is desirable that the notification control unit 68 performs control so that all the lights 7 in the building are turned on. As a result, the user can be surely notified that power has been restored.

  For example, the notification control unit 68 causes the breaker control unit 19 to connect the third branch breaker 18 via the communication line 24, thereby causing the third branch path 14 to be connected to the third connection path 22. At the same time, the notification control unit 68 switches the light switch 72 (see FIG. 1) so that the light 7 is turned on in ON / OFF.

  The presence / absence determining unit 69 determines whether there is a person in the building where the power recovery control system 1 is installed. Specifically, the presence / absence determination unit 69 receives the operation information based on the user's operation after the power recovery determination unit 61 determines that the power recovery has been performed, and then the inside / outside of the building where the power recovery control system 1 is installed. It is judged that there are people in.

  In the present embodiment, the presence / absence determining unit 69 operates information indicating that the lamp switch 72 has been operated, for example, to turn off one of the lamps within a predetermined time after the notification controller 68 turns on the lamp 7. When it is accepted, it is determined that there are people in the building. When the operation information is not received within a predetermined time after the light is turned on, the presence / absence determining unit 69 determines that there is no person in the building.

  The presence / absence determination unit 69 may determine whether at least one of the lamps is turned off based on a signal acquired from the branch path sensor 31. In this case, the presence / absence determining unit 69 may determine whether or not there is a person in the building using, as operation information, information indicating that the extinction is generated as a result of the determination.

  The partial connection unit 70 indicates the branch paths 12 to 14 indicated by the branch path ID information 40 associated with the conduction permission / denial information 41 indicating that the branch path information 36 may be conducted (denoted to be allowed to conduct). The first to third connection paths 20 to 22 are conducted.

  Specifically, the partial connection unit 70 refers to the branch path information 36 and extracts the branch path ID information 40 associated with the conduction permission / inhibition information 41 indicating that the branch connection information 36 may be conducted. And the partial connection part 70 is connected to the breaker control part 19 via the communication line 24 so that the branch breakers 16-18 to which the branch paths 12-14 indicated by the extracted branch path ID information 40 are connected are connected. Send a signal. As a result, the partial connection unit 70 is connected via the breaker control unit 19 so that the branch breakers 16 to 18 connected to the branch paths 12 to 14 that are indicated to be conductive in the branch path information 36 are connected. Control. That is, the partial connection unit 70 controls the branch paths 12 to 14 indicated to be conductive in the branch path information 36 via the breaker control unit 19 to be connected to the connection paths 20 to 22.

  All connection units 71 transmit a signal to breaker control unit 19 via communication line 24 so that all branch breakers 16 to 18 are connected when presence / absence determination unit 69 determines that there is a person. To do. Thereby, all the connection parts 71 control via the breaker control part 19 so that all the branch breakers 16-18 may be in a connection state. That is, all the connection parts 71 are made to make all the branch paths 12-14 shown to be able to be made conductive in the branch path information 36 via the breaker control part 19 collectively to the connection paths 20-22. ,Control.

  Processing executed by the control device 3 having the configuration described so far will be described with reference to the drawings.

  FIG. 10 is a flowchart showing processing executed by the control device 3 according to the first embodiment of the present invention.

  When the communication I / F unit 28 acquires the earthquake information, the earthquake prediction determination unit 44 acquires the earthquake information, and whether the installation location of the power recovery control system 1 is included in the area where the occurrence of the earthquake is predicted. It is determined whether or not (step S101). When it is determined that the area where the occurrence of the earthquake is predicted does not include the installation location of the power recovery control system 1 (step S101; No), the earthquake prediction determination unit 44 again determines that the communication I / F unit 28 has the earthquake. Wait until information is obtained.

  When it is determined that the installation location of the power recovery control system 1 is included in the area where the occurrence of the earthquake is predicted (step S101; Yes), the flag setting unit 46a sets “1” in the cause flag. Thus, the cause flag information 34 is updated (step S102a).

  The branch path information update unit 50 updates the branch path information 36 (step S103).

  FIG. 11 is a flowchart showing details of the branch path information update process (step S103).

  The signal acquisition unit 51 acquires a signal indicating the energization state of each of the branch paths 12 to 14 from the branch path sensor 31 (step S1031).

  Each processing unit 52 to 56 included in the branch path information update unit 50 refers to the signal acquired from the branch path sensor 31 by the signal acquisition unit 51 and performs the following processing (steps S1033 to S1038) for each branch path 12 to 14. ) Is repeated (loop A; step S1032).

  Each process (steps S1033 to S1038) in the loop A (step S1032) will be described using the first branch path 12 as an example.

  The operation determination unit 52 determines whether or not the first electrical device 5 connected to the first branch path 12 is operating based on the signal acquired from the branch path sensor 31 (step S1033).

  When it is determined that the first electrical device 5 is in operation (step S1033; Yes), the frequency specifying unit 53 determines the harmonics of the current flowing through the first branch 12 based on the signal acquired from the branch sensor 31. The wave generation pattern is identified by comparing it with the matching pattern. (Step S1034).

  The extraction unit 55 refers to the device information 35 and determines whether or not the device information 35 includes frequency information 38 indicating the frequency specified in the frequency specifying process (step S1034) (step S1035).

  When the extraction unit 55 determines that the device information 35 is included (step S1035; Yes), the device energization determination unit 55 extracts the device energization propriety information 39 associated with the frequency information 38. The device energization availability information 39 is referred to. Thus, the device energization determining unit 55 determines whether or not the first electric device 5 determined to be operating can be energized, and generates information indicating the determination result (step S1036).

  When it is determined that energization is allowed (step S1036; No), the branch path information generation unit 56 associates the branch permission information 41 indicating “permitted” with the branch path ID information 40 indicating the first branch path 12. The branch path information 36 is generated (step S1037).

  When it is determined that the electrical device is not operating (step S1033; No), when it is determined that there is no frequency information (step S1035; No), and when it is determined that the power supply should not be performed (step S1036). Yes), the branch path information generation unit 56 generates the branch path information 36 in which the branch path ID information 40 indicating the first branch path 12 is associated with the conduction permission / inhibition information 41 indicating “not permitted” (step S1038). .

  Similarly, the processing units 52 to 56 included in the branch path information update unit 50 execute the above-described processing (steps S1033 to S1038) for the second and third branch paths 13 and 14 (loop A; step S1032). ).

  The storage unit 57 stores the branch path information 36 of each of the branch paths 12 to 14 generated by the branch path information generation unit 56 in the storage unit 32 (step S1039).

Refer to FIG. 10 again.
The timer unit 47a starts measuring time (step S104a). The progress determination unit 48a determines whether or not the elapsed time measured by the time measuring unit 47a is equal to or less than the threshold T1 (step S105a).

  When it is determined that the elapsed time is not less than or equal to the threshold T1 (step S105a; No), the cause flag clear unit 44 updates the cause flag information 34 so as to set “0” in the cause flag (step S106).

  When it is determined that the elapsed time is equal to or less than the threshold value T1 (step S105a; Yes), the power failure determination unit 58 acquires a signal indicating the energization state in the power supply path 11 from the power supply path sensor 30, and uses the acquired signal as the acquired signal. Based on this, it is determined whether or not a power failure has occurred (step S107).

  When it is determined that a power failure has not occurred (step S107; No), the elapsed time determination process (step S105a) is continued.

  When it is determined that a power failure has occurred (step S107; Yes), the power supply control unit 59 switches the power supply for operating the control device 3 from the power of the power supply path 11 to the power of the standby power supply 29 (step S108). .

  The power recovery preparation unit 60 refers to the cause flag information 34. At this time, it is determined that the occurrence of an earthquake at the installation location is predicted (step S101: Yes), and it is determined that a power failure has occurred while the elapsed time is equal to or less than the threshold T1 (step S105a; Yes) ( Step S107; Yes). Therefore, “1” is set in the cause flag (step S102a). Since the cause flag indicated by the referenced cause flag information 34 is “1”, the power recovery preparation unit 60 transmits a signal to the breaker control unit 19 via the communication line 24 so that the main breaker 15 is shut off. (Step S109).

  The power recovery determination unit 61 acquires a signal indicating the state of energization in the power supply path 11 from the power supply path sensor 30, and determines whether power has been recovered based on the acquired signal (step S110). When it is determined that the power has not been recovered (step S110; No), the power recovery determination unit 61 continues the power recovery determination process (step S110).

  When it is determined that the power has been restored (step S110; Yes), the power restoration control unit 62 establishes the branch paths 12 to 14 to be electrically connected to the power supply path 11 based on the branch path information 36. Is controlled (step S111). As a result, the power recovery control unit 62 restores the power supply to each of the branch paths 12 to 14 that is safe even when the power supply path 11 is conducted.

  FIG. 12 is a flowchart showing details of the power recovery control process (step S111).

  The mode determination unit 63 refers to the cause flag information 34 at the time of power recovery. When the referred cause flag is “1”, the mode determination unit 63 determines that the mode is the earthquake mode (step S1111; earthquake mode). When the referred cause flag is “0”, the mode determination unit 63 determines that the normal mode is set (step S1111; normal mode).

  In the present embodiment, in the power recovery preparation process (step S109), as described above, the cause flag indicated by the cause flag information 34 is “1”, and the cause flag is not changed thereafter. Therefore, when the power recovery control process (step S111) is executed in the present embodiment, the cause flag indicated by the cause flag information 34 is “1”. Therefore, in the mode determination process (step S1111) of the present embodiment, the mode determination unit 63 determines the earthquake mode (step S1111; earthquake mode).

  When it is determined that the earthquake mode is selected (step S1111; earthquake mode), the all-blocking unit 66 transmits a signal to the breaker control unit 19 via the communication line 24, whereby the first to third branch breakers 16 to 18 are transmitted. Are all cut off (step S1112).

  The master breaker connection unit 67 transmits a signal to the breaker control unit 19 via the communication line 24, thereby bringing the main breaker 15 that is in the cut-off state by executing the main breaker cut-off process (step S109) into the connected state. (Step S1113).

  The notification control unit 68 transmits a signal to the breaker control unit 19 via the communication line 24 to place the third branch breaker 18 in a connected state and turn on the light switch 72 (step S1114). At this time, since the main breaker 15 is connected by the main breaker connection process (step S1113), the light is turned on by setting the third branch breaker 18 to the connected state and turning on the light switch 72.

  The presence / absence determination unit 69 is a building in which the power recovery control system 1 is installed based on whether or not at least one lamp switch 72 is operated within a predetermined time after the notification controller 68 lights the lamp 7. It is determined whether or not there is a person inside (step S1115).

  The presence / absence determination unit 69 determines that there is a person when receiving operation information indicating that at least one lamp switch 72 is operated (step S1115; present). Further, the presence / absence determination unit 69 determines that there is no person when the operation information is not received (step S1115; not).

  When it is determined that there is a person (step S <b> 1115; present), all the connection parts 71 refer to the normal conduction information 37. All connection units 71 transmit signals to breaker control unit 19 via communication line 24 to place all branch breakers 16 to 18 that are normally connected in normal continuity information 47 into a connected state. (Step S1116).

  When it is determined that there is no person (step S1115; not), the partial connection unit 70 refers to the branch path information 36 and the normal conduction information 37. The partial connection unit 70 transmits the signal to the breaker control unit 19 via the communication line 24, thereby causing the branch breakers 16 to 18 of the branch breakers 16 to 18 indicated as being normally connected in the normal conduction information 47. Based on the branch path information 36, the connection state is set (step S1118). At this time, the branch breakers 16 to 18 to be connected are associated with the branch paths 12 to 14 that may be conducted in the branch path information 36, that is, the conduction permission / denial information 41 indicating that the branch breakers 16 to 18 may be conducted. Are the branch paths 12 to 14 indicated by the branch path ID information 40.

  By executing the partial connection process (step S1118), the branch breakers 16 to 18 connected to the branch paths 12 to 14 that are indicated to be conductive in the branch path information 36 are in the connected state. Further, the branch breakers 16 to 18 connected to the branch paths 12 to 4 that are indicated as not to be conducted in the branch path information 36 are cut off. Branch breakers 16-18 wait in that state after the partial connection process (step S1118) is executed. Meanwhile, the presence / absence determination unit 69 continues the presence / absence determination process (step S1115) until it is determined that there is a person by receiving predetermined operation information based on the user's operation (step S1115; present).

  When it is determined that there is a person (step S1115; present), all the connection units 71 connect all of the branch breakers 16 to 18 that are indicated in the normal conduction information 47 as being normally connected as described above. The state is set (step S1116).

  When all connection parts 71 connect all branch breakers 16 to 18 (step S1116), earthquake mode unit 65 ends the power recovery control process (step S111).

  When the normal mode is determined (step S1111; normal mode), the normal mode unit 64 refers to the normal conduction information 37. The normal mode unit 64 transmits a signal to the breaker control unit 19 via the communication line 24, thereby setting all the breakers 15 to 18 that are normally connected in the normal conduction information 47 to the connected state ( Step S1119). As a result, the normal mode unit 64 ends the power recovery control process (step S111).

  Returning to FIG. 10 again, the flag clear unit 49 receives information indicating that from the power recovery control unit 62 that executed the power recovery control process (step S111), and sets “0” in the cause flag (step S112). ). As a result, the processing / control unit 33a ends the processing.

  As described above, according to the present embodiment, after the power is restored, the branch paths 12 to 14 to which the electrical devices 5 to 7 that do not generate heat that causes a fire even if activated are connected to the power paths. 11 is conducted. Therefore, the electrical devices 5 to 7 can be operated immediately after the power recovery. In addition, even after power recovery, when there is no person, the branch paths 12 to 14 connected to the electrical devices 5 to 7 that generate heat that generates a fire when activated are connected to the power supply path 11. I won't let you. Therefore, even after the power recovery, the electrical devices 5 to 7 that generate such heat can be kept stopped. That is, only the electric devices 5 to 7 that are safe even if activated can be activated immediately after power recovery. Therefore, after a power failure due to an earthquake occurs, when the power failure ends (recovers), it is possible to improve convenience for the user while ensuring safety.

  Moreover, in this embodiment, the earthquake prediction judgment part 44 acquires earthquake information, and when a power failure occurs, it judges whether the cause of a power failure is an earthquake based on the earthquake information. Therefore, it is possible to make a determination based on reliable information without using a sensor for detecting an earthquake.

  Further, in the present embodiment, the branch path information update unit 50 automatically updates the branch path information 36. Moreover, in the 1st-3rd electric equipment 5-7 connected to each branch path 12-14, if there is what fixed the branch paths 12-14 connected like a refrigerator, etc., In some cases, the branch paths 12 to 14 are appropriately changed, such as a stove or a dryer. It is very troublesome for the user to update the branch path information 36 every time the branch paths 12 to 14 connecting the electrical devices 5 to 7 are changed. Therefore, it is possible to save the user from setting the branch path information 36 by the branch path information update unit 50 that automatically updates the branch path information 36.

  Furthermore, in the present embodiment, the branch path information update unit 50 executes the branch path information update process (step S103) after the flag setting process (step S102a). As described above, the branching path information 36 after an earthquake is predicted in the earthquake prediction determination process (step S101), that is, immediately before the occurrence of a power failure can be stored in the storage unit 32. Therefore, the branch path information 36 at the time of power recovery accurately represents the first to third electric devices 5 to 7 connected to the respective branch paths 12 to 14. Therefore, when power is restored, the branch paths 12 to 14 can be more safely conducted.

  Further, in the present embodiment, the branch path information update unit 50 performs branch path information update processing (step S103), that is, a branch to which the electrical devices 12 to 14 that are operating immediately before a power failure occurs are connected. The paths 12 to 14 may be electrically connected to the power supply path 11 at the time of power recovery. Even if it is connected to the branch paths 12 to 14 immediately before the occurrence of a power failure, it is considered that the necessity to enable the electrical devices 12 to 14 that are not operating at that time to operate immediately after power recovery is low. Moreover, even if it is the electric equipments 12-14 which were stopped just before the occurrence of a power failure, there is a danger that the switch is turned on due to a fallen object of an earthquake and the like and is activated to generate heat. Therefore, as in the present embodiment, the convenience to the user is reduced by conducting the power to the branch paths 12 to 14 to which the electrical devices 12 to 14 operating immediately before the power failure occurs are connected at the time of power recovery. Safety can be ensured without this.

  Furthermore, in this embodiment, it is confirmed whether or not there is a person at the installation location. And when there is a person, the branch breakers 16-18 are returned to the normal state. As a result, the user can return the branch breakers 16 to 18 to a normal state only by performing a predetermined operation such as turning off the light switch 72, for example, thus improving the convenience for the user. It becomes possible. In addition, when there is no person, as described above, the branch paths 12 to 14 to which the electrical devices 5 to 7 that do not generate heat even when activated are connected are connected to the power supply path 11. . As a result, it is possible to improve the convenience of the user while ensuring safety even if there are no people.

  Furthermore, in this embodiment, when the branch paths 12 to 14 to which the electrical devices 5 to 7 that do not generate heat after the power recovery are connected are connected to the power supply path 11, the earthquake mode unit 65 Wait until the person returns (step S1115). Then, when it is confirmed that the person has returned (step S1115; Yes), the earthquake mode unit 65 causes all of the branch paths 12 to 14 to conduct to the power supply path 11 (step S1116). Accordingly, it is possible to improve convenience for the user by returning the branch breakers 16 to 18 to the normal state while ensuring safety by confirming that the person has returned.

  Further, in the present embodiment, the power recovery preparation unit 60 executes a main breaker cutoff process (step S109) as preparation for the power recovery control process (step S111) before power recovery. As a result, conduction between all the branch paths 12 to 14 and the power supply path 11 at the time of power recovery can be interrupted, and safety at the time of power recovery can be ensured.

  Further, in the present embodiment, in the power recovery control process (step S111) after the master breaker shut-off process (step S109) is executed, after all the branch breakers 16 to 18 are shut off (step S1112), the master The breaker 15 is brought into a connected state (step S1113). Thereby, it becomes possible to employ | adopt the electric light 7 as a notification means. In addition, since the continuity to the branch paths 16 and 17 other than the third branch path 18 to which the lamp 7 is connected is cut off, it is possible to ensure safety during power recovery.

  Furthermore, in this embodiment, the electric lamp 7 is employ | adopted as a notification means to notify a user of a power recovery. This makes it easier for the user to notice that the power has been restored, rather than adopting the display unit 26, the speaker 27, etc. as the display means, as will be described later. become.

  Further, the presence / absence determination unit 69 determines whether or not there is a person in the building where the power recovery control system 1 is installed by operating the light switch 72. For example, when all the lamps 7 are turned on, the user usually operates the lamp switch 72 to turn off the unnecessary lamps 7. According to the present embodiment, since it is determined whether or not a person is present by an action normally performed by the user to turn off the unnecessary light 7, it is not necessary for the user to memorize a special operation. The burden on the user can be reduced. Therefore, it is possible to improve user convenience.

(Embodiment 2)
In the first embodiment, when earthquake information is acquired and a power failure occurs, it is determined whether the cause of the power failure is an earthquake based on the earthquake information. In Embodiment 2, it is determined whether the cause of a power failure is a disaster based on the power failure time. In this embodiment, a case where a power failure occurs due to an earthquake will be described as an example, but an earthquake is an example of a disaster.

  The configuration of the power recovery control system according to the second embodiment is the same as the configuration of the power recovery control system according to the first embodiment shown in FIG. Therefore, the description regarding the configuration of the power recovery control system according to the present embodiment is omitted here.

  Unlike the processing / control unit 33a according to the first embodiment, the processing / control unit 33b according to the second embodiment does not include the earthquake prediction determination unit 44 (see FIG. 6). The processing / control unit 33b includes a cause flag setting unit 45b having a different configuration in place of the cause flag setting unit 45a included in the processing / control unit 33a. The other elements 50 to 71 (see FIGS. 13, 8 and 9) included in the other processing / control unit 33 b are the same as those of the processing / control unit 33 a. Therefore, in the present embodiment, the cause flag setting unit 45b will be described, and the description of the elements 50 to 71 included in the other processing / control unit 33b will be omitted.

  FIG. 14 shows a detailed configuration of the cause flag setting unit 45b according to the second embodiment. The cause flag setting unit 45b includes a flag setting unit 46b, a timing unit 47b, a progress determination unit 48b, and a flag clear unit 49, as shown in FIG.

  The flag setting unit 46b updates the cause flag information 34 so that the cause flag is set to “1” when the power failure time exceeds the threshold value T2.

  When the power failure determination unit 58 determines that a power failure has occurred, the timer unit 47b measures the elapsed time after the determination is made, that is, the power failure time.

  The progress determining unit 48b determines whether or not the elapsed time measured by the time measuring unit 47b has exceeded the threshold value T2. The threshold value T2 is preset and held in the storage unit 32.

  Since the flag clear unit 49 is the same as that of the first embodiment, the description thereof is omitted here.

  FIG. 15 is a flowchart illustrating processing executed by the control device 3 according to the second embodiment.

  The branch path information update unit 50 executes a branch information update process (step S103). The power failure determination unit 58 executes a power failure determination process (step S107). When it is determined that no power failure has occurred (step S107; No), the branch path information update unit 50 continues the branch information update process (step S103). Here, the branch information update process (step S103) may be executed at a preset period (for example, every hour) or at a time. When it is determined that a power failure has occurred (step S107; Yes), the power supply control unit 59 executes a power supply switching process (step S108). The power recovery preparation unit 60 executes a main breaker cutoff process (step S109).

  Since the branch path information update process (step S103), the power failure determination process (step S107), the power switch process (step S108), and the main breaker cutoff process (step S109) have been described in the first embodiment, a detailed description will be given here. Omitted.

  The timer unit 47b starts measuring time (step S104b).

  The power recovery determination unit 61 executes a power recovery determination process (step S110). When it is determined that the power has not been recovered (step S110; No), the power recovery determination unit 61 continues the power recovery determination process (step S110). Since the power recovery determination process (step S110) has been described in the first embodiment, a detailed description thereof is omitted here.

  When it is determined that power has been restored (step S110; Yes), the progress determination unit 48b determines whether or not the elapsed time measured by the time measuring unit 47b has exceeded the threshold value T2 (step S105b).

  When it is determined that the elapsed time has exceeded the threshold T2 (step S105b; Yes), the flag setting unit 46b updates the cause flag information 34 so as to set “1” in the cause flag (step S102b).

  When the flag setting process (step S102b) is executed and when it is determined that the elapsed time does not exceed the threshold T2 (step S105b; No), the power recovery control unit 62 performs the power recovery control process (step S111) is executed. The flag clear unit 49 performs a flag clear process (step S112). Since the power recovery control process (step S111) and the flag clear process (step S112) have been described in the first embodiment, detailed description thereof is omitted here.

  As a result, the processing / control unit 33b ends the processing.

  As described above, according to the present embodiment, when a power failure continues longer than the threshold value T2, it is determined that the cause of the power failure is a disaster. Therefore, even if the communication I / F unit 28 is not provided, the cause of the power failure can be determined. Moreover, although the communication I / F unit 28 is provided, the cause of the power failure can be determined even when the earthquake information cannot be acquired for some reason.

  If a user operates an electric device that generates heat that causes a fire at the time of a disaster, and the power failure continues for a long time, the user may forget to turn off the electric device. According to the present embodiment, since the power supply to such an electrical device is interrupted at the time of power recovery after a power failure continues for longer than the threshold T2, it is possible to prevent a fire due to the heat of the electrical device and ensure safety. Is possible. In addition, even when it is determined that the cause of the power failure is a disaster because the power failure lasted longer than the threshold T2, as in the first embodiment, the power supply that does not generate heat that causes a fire is restored. Sometimes power is supplied. For this reason, it is possible to improve the convenience of the user rather than shutting off the power supply to all the electric devices.

  If the power failure is shorter than the threshold T2, it is determined that the cause of the power failure is not a disaster. Therefore, it is possible to improve the convenience for the user without interrupting the power supply to the electric device due to a slight power failure.

  In the present embodiment, the power supply path sensor 30 detects a state of energization in the power supply path 11, and power supplied from the commercial power supply 4 flows through the power supply path 11. Recently, it is rare that the supply of power from the commercial power supply 4 is stopped except in the event of a disaster. However, unlike the embodiment, for example, when power supplied from a distributed power source such as a solar cell provided for each building flows in the power supply path 11, the solar cell has a short-time power outage or a decrease in supply power depending on circumstances such as the weather. Can occur. In such a case, according to the present embodiment, the power supply to the electric device is not interrupted due to a slight power failure, so that the convenience for the user can be improved.

  As mentioned above, although each embodiment of the present invention was described, the present invention is not limited to these embodiments. The present invention includes a combination of the embodiments and a combination of the following modifications. Furthermore, the present invention includes those in which changes or the like are appropriately added.

(Modification 1)
In each embodiment, the case where there are three branch paths and branch breakers has been described as an example, but any number of branch paths and branch breakers may be used. In each embodiment, the case where one branch path 12 to 14 is connected to each branch breaker 16 to 18 has been described as an example. However, a plurality of branch paths are connected to each branch breaker 16 to 18. May be.

  When a plurality of branch paths are connected to one branch breaker 16 to 18, the branch breakers 16 to 18 to which the plurality of branch paths are connected cause conduction between the plurality of branch paths and the connection path. Can be switched at once.

  In this case, for example, when an electrical device that generates heat that causes a fire is not connected to all of the plurality of branch paths, the control device 3 causes the plurality of branch paths to conduct to the power supply path 11 when power is restored. The branch breakers 16 to 18 are controlled as follows. In addition, when there is a branch path to which any one of the plurality of branch paths is connected to an electrical device that generates heat, the control device 3 does not connect the plurality of branch paths to the power supply path 11 when power is restored. Control branch breakers 16-18. Furthermore, when there is a branch path in which it is unclear whether or not an electrical device that generates heat is connected to one of the plurality of branch paths, the control device transfers the plurality of branch paths to the power supply path 11 when power is restored. It is desirable to control the branch breaker so that it does not conduct in order to prevent a fire due to the heat of the electrical equipment.

(Modification 2)
In the embodiment, the mechanism for switching the conduction state included in each of the breakers 15 to 18 is a relay, but is not limited thereto. For example, the mechanism that switches the conduction state may be configured by a switch that switches between a connection state and a cutoff state by being displaced, and a mechanism that displaces the switch. As a mechanism for displacing the switch, a mechanism that applies a mechanical force to the switch by appropriately combining an urging force, a magnetic force, an electromagnetic force, or the like, such as a solenoid, can be employed. In addition, it is desirable that the mechanism for switching the conduction state has a configuration capable of maintaining the states of the breakers 15 to 18 even during a power failure.

(Modification 3)
In each embodiment, although the control apparatus 3 controlled the breaker provided in the distribution board 2, the object which the control apparatus 3 controls is not restricted to this. An object to be controlled by the control device 3 is a device, device, or the like (conduction switching device) that can switch between a connection state in which the branch path is directly or indirectly connected to the power supply path 11 and a cutoff state in which the branch path is not connected. I just need it.

  As a specific example, the conduction switching device may be provided between each branch breaker and each outlet. In this case, the power supply path is an energization path that is connected to the main breaker from a power supply such as a commercial power supply, as in the embodiment. The branch path is an energization path that electrically connects the conduction switching device and the outlet. The connection path is an energization path that electrically connects the main breaker and the conduction switching device, and includes a branch breaker on the way.

  In this case, the branch breaker may be always in a connected state, or may be controlled in conjunction with the main breaker so that all branch breakers are in the same state as the main breaker.

  Further, the branch breaker may be controlled by the control device depending on whether or not the conduction switching device conducts to an outlet electrically connected to the branch breaker. For example, when the conduction switching device conducts to at least one of the outlets electrically connected to the branch breaker, the control device may control the branch breaker so as to be in a connected state. Further, for example, when all of the outlets electrically connected to the branch breaker by the conduction switching device do not conduct, the control device may control the branch breaker so as to be in a cut-off state.

(Modification 4)
The control device 3 may include an earthquake sensor, and may determine whether the cause of the power failure is an earthquake based on a signal generated by the earthquake sensor. In this case, for example, when a power outage occurs within a predetermined time after the occurrence of the earthquake, it may be determined that the cause of the power outage is an earthquake. Moreover, when the power failure does not occur after the predetermined time has elapsed after the occurrence of the earthquake, it may be determined that the cause of the power failure is not an earthquake.

(Modification 5)
In the embodiment, the case where the power source that provides power via the power path 11 is the commercial power source 4 has been described as an example, but the power source is not limited thereto. For example, the power source may include a distributed power source. In this case, it is preferable to determine that a power failure has occurred when the power supply from the commercial power supply 4 and the distributed power supply is stopped (or has become below a certain level). Further, it may be determined that the power has been restored when the power supply from either the commercial power supply 4 or the distributed power supply is restored.

(Modification 6)
The control device 3 or each of the electric devices 5 to 7 may include a device sensor that generates a signal indicating the state of each of the electric devices 5 to 7. The branch path information update unit 50 may acquire a signal from the device sensor and incorporate the content of the signal into a determination element for generating the conduction permission / rejection information 41. For example, when a signal indicating an abnormality in the electrical devices 5 to 7 is acquired, the branch path information update unit 50 determines the branch path ID information 40 indicating the branch paths 12 to 14 to which the electrical devices 5 to 7 are connected. In addition, the branch path information 36 associated with the conduction permission / denial information 41 that is “not permitted” may be generated. Further, when a signal indicating that the electrical devices 5 to 7 are normal is acquired, the branch path information update unit 50 considers other determination elements such as the appliance energization availability information 39 and the branch path information 36. Should be generated. Specifically, for example, when all of the determinations regarding other determination elements are affirmed, the branch path ID information 40 indicating the branch paths 12 to 14 to which the electrical devices 5 to 7 are connected is set to “permitted”. The branch path information 36 that associates the permission / rejection information 41 may be generated.

(Modification 7)
The timing unit 47a according to the first embodiment starts timing after the branch path information update process (step S103) (see FIG. 10), but the timing of timing by the timing unit 47a is not limited to this. The start time of time measurement by the time measuring unit 47a may be a time point set appropriately after the communication I / F unit 28 acquires earthquake information. As an example of the timing for starting the timing by the timing unit 47a, when the communication I / F unit 28 acquires earthquake information, the earthquake prediction determination process (step S101) determines that an earthquake at the installation location is predicted. , Immediately after the flag setting process (step S102a) is completed.

(Modification 8)
The flag setting process (step S102a) may be executed when appropriately set as long as it is after the earthquake prediction determination process (step S101). Further, the branch path information update process (step S103) may be executed when appropriately set after the communication I / F unit 28 acquires the earthquake information. Further, the order of the flag setting process (step S102a), the branch path information update process (step S103), and the timing start process (step S104a) is not limited to the order described in the first embodiment (see FIG. 10), and is appropriately determined. It may be replaced.

(Modification 9)
In the embodiment, the branch path information 36 is generated and stored (set) by the branch path information update unit 50, but may be set in advance by a user or the like. In this case, the control device 3 may not include the branch path information update unit 50, and the partial connection unit 70 may refer to the preset branch path information 36 and conduct in the branch path information 36. The branch paths 12 to 14 associated with the conduction permission / inhibition information 41 indicating this may be conducted.

(Modification 10)
The branch path information 36 may include operation information in addition to the branch path ID information 40 and the conduction permission / rejection information 41. The operation information is information indicating whether or not each electrical device 5 to 7 connected to each branch path 12 to 14 is operating when a power failure occurs. In this case, the branch path information generation unit 56 may generate the branch path information 36 including the operation information of each of the branch paths 5 to 7 according to the determination result of the operation determination unit 52. The storage unit 57 may store the branch path information 36 generated by the branch path information generation unit 56 in the storage unit 32. In addition, the partial connection unit 70 refers to the branch path information 36, indicates that the conduction permission / denial information 41 may be conducted, and specifies the branch paths 12 to 14 indicating that the operation information is operating. It is good to make it conductive.

(Modification 11)
In the embodiment, the user is notified of the power recovery by turning on the lamp 7, but the notification means is not limited to the lamp 7. For example, the notification control unit 68 may display information indicating that power has been restored on the display unit 26 or may cause the speaker 27 to generate a predetermined sound. In this case, for example, when the presence / absence determination unit 69 acquires information indicating that a predetermined button of the input unit 25 is pressed within a predetermined time after display or sound is generated, Judge that there is.

  And when not using the electric light 7 for a notification means, the detail of a power recovery control process (step S111) may be shown in FIG. 16 instead of what is shown in FIG.
