However, other types of detectors (for example, a resistance type ammeter that detects a voltage drop) are commercially available. The form which detects the electric current value or electric power value supplied to a storage battery from a power supply may be sufficient.

  Furthermore, in this embodiment, the case where the personal authentication information is ID information stored in the IC card will be described.

Is, for example, 1500A. That is, the parking lot shown in FIG. 3 has a space where 32 vehicles can be parked, but the number of vehicles that can be charged simultaneously is 10. Accordingly, when the storage battery of 10 vehicles is being charged at the same time and the user who desires charging succeeds in personal authentication and selects and inputs an empty partition number, the server device 1 Power supply is not permitted. In this case, for example, a standby screen indicating that charging cannot be started because the number of vehicles that can be charged simultaneously is exceeded is displayed on the LCD 216 of the authentication control device 2.

-Functional configuration of power supply control system 100-
FIG. 6 is a block diagram illustrating an example of a functional configuration of the power supply control system 100 illustrated in FIG. 1. The server device 1 includes a CPU, ROM, RAM, HDD (Hard disk drive), and the like. The CPU reads and executes a control program or the like stored in a ROM or the like. The ROM is a memory that stores a control program and the like in advance. The RAM is a memory used as a working memory, a temporary storage memory, or the like. The HDD is a memory that stores various information such as ID information used for personal authentication.

  Here, the server device 1 reads out a control program stored in the ROM and executes it by the CPU, whereby the power reception unit 101, the full charge determination unit 102, the interruption determination unit 103, the interruption instruction unit 104, and the number of charges calculated Unit 105, charging power calculation unit 106, authentication unit 107, permission determination unit 108, and permission instruction unit 109.

  Here, the relay controller 3 functions as the communication control unit 301, the opening / closing unit 302, and the detection unit 303 by reading out a control program stored in the ROM 312 and executing it by the CPU 311.

  The communication control unit 301 is a functional unit that controls information communicated via the first communication port 3a and the second communication port 3b. The function of the communication control unit 301 formed in the CPU 311 of the relay controller 3k (k = 1, 2,..., N) will be specifically described.

When the communication control unit 301 receives instruction information (permission instruction information, interruption instruction information) that is transmitted from the server device 1 and is input via the authentication control device 2 to switch power supply or interruption from the first communication port 3a. Is a functional unit that determines whether or not the IP address included in the instruction information matches the IP address assigned to the relay controller 3k. The communication control unit 301 corresponds to a part of “communication control means” described in the claims. When the IP address included in the instruction information matches the IP address assigned to the relay controller 3k, the relay 4k is controlled to open / close via the opening / closing unit 302 according to the instruction information. On the other hand, if the IP address included in the instruction information does not match the IP address assigned to the relay controller 3k, the instruction information is sent from the second communication port 3b to the lower relay controller 3 (k + 1).

  Furthermore, when the power value information is input from the lower relay controller 3 (k + 1) via the second communication port 3b, the communication control unit 301 transmits the input power value information from the first communication port 3a. And sent to the upper relay controller 3 (k-1) or the authentication control device 2.

  FIG. 7 is an explanatory diagram showing a route through which instruction information (permission instruction information, blocking instruction information) from the server device 1 is transmitted to the relay 4 in the wiring diagram shown in FIG. Here, a route through which the instruction information from the server device 1 is transmitted to the relay 43 will be described with reference to FIG. In addition, the path | route through which the instruction information from the server apparatus 1 is transmitted to the relay 43 is shown with an arrow indicating a transmission direction with a thick line in FIG.

  First, the instruction information from the server device 1 is received by the authentication control device 2 via the Internet 8. The received instruction information is transmitted from the authentication control device 2 to the first communication port 31 a of the relay controller 31. The communication control unit 301 of the relay controller 31 determines that the IP address given to the instruction information received via the first communication port 32a does not match the IP address given in advance to the relay controller 31, and the relay controller The data is transmitted from the second communication port 31 b of 31 to the first communication port 32 a of the relay controller 32.

  Next, the communication control unit 301 of the relay controller 32 determines that the IP address assigned to the instruction information received via the first communication port 32a does not match the IP address assigned in advance to the relay controller 32. Then, the data is transmitted from the second communication port 32 b of the relay controller 32 to the first communication port 33 a of the relay controller 33.

  Then, the communication control unit 301 of the relay controller 33 determines that the IP address given to the instruction information received via the first communication port 33a matches the IP address given in advance to the relay controller 33, and opens / closes The relay 43 is ON / OFF controlled based on the instruction information via the unit 302 (see FIG. 6).

  When the permission instruction information is received from the server device 1 in this way, the IP address included in the received permission instruction information matches the IP address previously assigned to the outlet 6 (relay controller 3). In addition, since the supply of power to the storage battery is permitted via the relay 4, the power supplied to the storage batteries of a plurality of vehicles can be controlled with a simple configuration.

  That is, the relay controller 3 that controls the supply and interruption of power for each outlet 6 has a function of determining whether or not the IP addresses match (corresponding to the function of the communication control unit 301), and the relay 4 Since a function for instructing the supply and cut-off of power (corresponding to the function of the opening / closing unit 302) may be provided, a device for controlling the supply and cut-off of power for each outlet 6 (here, the relay controller 3) is simplified It can be set as a simple structure.

Further, since the identification information given to the relay controller 3 is IP address information, more appropriate identification information can be set in the relay controller 3. That is, the communication device such as the server device 1 can easily transmit various information such as permission instruction information to the relay controller 3 via the network such as the Internet 8 by using the IP address information. .

  In the present embodiment, a case where the identification information given to the relay controller 3 is an IP address will be described, but the identification information given to the relay controller 3 may be other identification information. For example, when the identification information given to the relay controller 3 is address information indicating the position of the relay controller 3, appropriate identification information can be set in the relay controller 3. That is, a communication device such as the server device 1 easily transmits various information such as permission instruction information to the relay controller 3 via a network such as a LAN (Local Area Network) by using address information. be able to.

  Further, the communication control unit 301 of the relay controller 3k (k = 1, 2,..., N) arranges from the first communication port 3ka on the upstream side that is the side close to the authentication control device 2 or the authentication control device 2. Permit instruction information (or block instruction information) is received from one relay controller 3 (k-1) that has been received, and the IP address information included in the received permit instruction information (or block instruction information) is relay controller. It is determined whether the IP address information set in advance for 3k matches. When it is determined that they do not match, the relay controller 3k of the relay controller 3k has one relay controller 3 (k + 1) arranged on the downstream side that is the side away from the authentication control device 2 from the second communication port 3b. The permission instruction information (or blocking instruction information) is output to. Therefore, the permission instruction information (or blocking instruction information) output by the server device 1 (specifically, the permission instruction unit 109) to one relay controller 31 arranged at a position closest to the authentication control device 2 Is transmitted to the relay controller 3k (k = 2, 3,..., N), the server device 1 (specifically, the permission instruction unit 109 or the cutoff instruction unit 104) The permission instruction information (or blocking instruction information) can be transmitted to the relay controller 3k (k = 1, 2,..., N) with a simple configuration.

  Further, since each relay controller 3k (k = 1, 2,..., N) has the same function, the relay controller 3 (in addition to the second communication port 3b of the relay controller 3n disposed on the most downstream side). By connecting the first communication port 3a of (n + 1), a relay controller can be easily added.

  In the present embodiment, the relay controller 3k communicates with the authentication control device 2 or one relay controller 3 (k-1) arranged on the upstream side and one relay controller 3 (k + 1) arranged on the downstream side. Although the case where it can connect is demonstrated, even if the authentication control apparatus 2 and each relay controller 3k (k = 1, 2, ..., n) are connected so that communication is possible via a hub etc. Good. In this case, the communication time between the authentication control device 2 and each relay controller 3k is shortened.

  FIG. 8 is an explanatory diagram showing a path through which power value information generated based on the detection result of CT53 is transmitted to the server apparatus 1 in the wiring diagram shown in FIG. Here, a path through which power value information generated based on the detection result of CT53 is transmitted to server apparatus 1 will be described with reference to FIG. In addition, the path | route through which the information (or signal) from CT53 is transmitted to the server apparatus 1 is shown with the arrow which shows a transmission direction with a thick line in FIG.

First, the current value supplied to the storage battery mounted on the vehicle via the outlet 63 is detected by the CT 53, and a signal indicating the detected current value is input to the relay controller 33. And the detection part 303 of the relay controller 33 calculates an electric power value based on the electric current value signal from CT53. Then, the communication control unit 301 of the relay controller 33 adds the IP address information of the relay controller 33 to the calculated power value information, and the second communication port of the relay controller 32 from the first communication port 32a of the relay controller 33. To 32b.

  The communication control unit 301 of the relay controller 32 transmits the power value information received from the second communication port 32b from the first communication port 32a. The communication control unit 301 of the relay controller 31 transmits the power value information received from the second communication port 31b to the authentication control device 2 from the first communication port 31a. The authentication control device 2 transmits the power value information received from the relay controller 31 to the server device 1 (here, the current receiving unit 101) via the Internet 8. In this way, the power value information generated based on the detection result of the CT 53 is transmitted to the server device 1 via the relay controller 33, the relay controller 32, the relay controller 31, and the authentication control device 2 in order. .

  Returning to FIG. 6 again, the functional configuration of the power supply control system 100 will be described. The opening / closing unit 302 of the relay controller 3 is based on instruction information (permission instruction information, blocking instruction information) received from the server device 1 (here, the permission instruction unit 109 and the blocking instruction unit 104) via the communication control unit 301. This is a functional unit that turns the relay 4 on and off. The opening / closing part 302 corresponds to “switching control means” described in the claims. Specifically, the instruction information (permission instruction information, blocking instruction information) from the server device 1 is transmitted to the communication controller of the relay controller 3 via the Internet 8, the authentication control device 2, and the upstream relay controller 3. 301 is transmitted to the opening / closing unit 302 (see FIG. 7).

  The detection unit 303 calculates a power value based on the current value signal detected by the CT 5, assigns IP address information corresponding to the relay controller 3 to the calculated power value information, and the server device 1 (here Then, it is a functional unit that outputs to the power receiving unit 101). Here, the detection unit 303 corresponds to a part of the power detection means described in the claims. Specifically, the power value information from the detection unit 303 of the relay controller 3 is transmitted to the power reception unit 101 of the server device 1 via the upstream relay controller 3, the authentication control device 2, and the Internet 8. (See FIG. 8).

  The power reception unit 101 is a functional unit that receives power value information from the detection unit 303 of the relay controller 3. The power receiving unit 101 corresponds to a part of the power detection unit described in the claims.

  The full charge determination unit 102 is a functional unit that determines whether or not a storage battery mounted on a vehicle that is fed from each outlet 6 is in a fully charged state. The full charge determination unit 102 corresponds to a part of the “blocking determination unit” described in the claims. Specifically, the full charge determination unit 102 determines whether or not the battery is fully charged based on the power value information from the detection unit 303 of the relay controller 3 received by the power reception unit 101. For example, the full charge determination unit 102 has a state in which the power value from the detection unit 303 of the relay controller 3 is equal to or lower than a preset power threshold (eg, 3 W) is greater than or equal to a preset time threshold (eg, 10 seconds). When it continues, it determines with it being a full charge state.

  The shut-off determination unit 103 is a functional unit that determines, for each relay controller 3, whether or not a shut-off condition that is a condition for shutting off a preset power supply is satisfied. The blocking determination unit 103 corresponds to a part of the “blocking determination unit” described in the claims. Here, the interruption determination unit 103 determines whether or not the full charge determination unit 102 determines that the battery is in the fully charged state for each relay controller 3 that is permitted to supply power by the permission determination unit 108.

The shut-off instruction unit 104 is given IP address information corresponding to the relay controller 3 determined to satisfy the shut-off condition by the shut-off determining unit 103, and sends the shut-off instruction information, which is instruction information for shutting off power supply, to the Internet. 8 and a functional unit that transmits to the relay controller 3 via the authentication control device 2. The shut-off instruction unit 104 corresponds to “shut-off instruction means” described in the claims.

  In this way, the interruption condition, which is a condition for cutting off the supply of electric power, is a condition that the storage battery mounted on the vehicle being fed from each outlet 6 is in a fully charged state, so the storage battery is in a fully charged state. In this case, the power supplied to the vehicle storage battery can be cut off. Therefore, when the storage battery is fully charged, the power supplied to the storage battery of the vehicle is cut off, so that it is possible to supply power to the storage battery of another vehicle. A plurality of outlets 6 arranged can be used effectively.

  In the present embodiment, the case where the interruption condition, which is a condition for cutting off the supply of electric power, is a condition that the storage battery mounted on the vehicle fed from each outlet 6 is in a fully charged state will be described. The condition may include other conditions. For example, the blocking condition may include a condition that the plug is disconnected from the outlet 6 due to some circumstances (for example, a child's mischief or strong wind). In this case, the plurality of outlets 6 provided in the power supply control system 100 can be used more effectively.

  The charging number calculation unit 105 is a functional unit that calculates a charging number NA that is the number of relay controllers 3 that are being charged when a charging request is received by the authentication unit 107. The number-of-charge calculation unit 105 corresponds to a “number-of-charge calculation unit” described in the claims. Specifically, the number-of-charges calculation unit 105 is formed in the “charging address storage unit” that is a storage unit that is formed in the HDD of the server device 1 and stores IP address information corresponding to the outlet number being charged. The charging number NA is obtained by counting the number of stored IP address information. The charged number calculation unit 105 also obtains the charged number NA even when the supply of power from the relay controller 3 is cut off by the cut-off determining unit 103.

  The charging power calculation unit 106 is a functional unit that calculates the charging power WA that is the sum of the power values received by the power reception unit 101 when the authentication unit 107 receives a charging request. The charging power calculation unit 106 corresponds to “charging power calculation means” described in the claims. Specifically, the charging power calculation unit 106 calculates the charging power WA by, for example, calculating the sum of the power values of the power value information including the IP address information stored in the “charging address storage unit”. The charging power calculation unit 106 also obtains the charging power WA when the interruption determination unit 103 interrupts the supply of power from the relay controller 3.

  The authentication unit 107 includes a personal authentication process that is a process for determining whether or not a user who wants to charge a storage battery mounted on a vehicle is a user registered in the server device 1, and an outlet that the user desires to use. It is a functional unit that performs an outlet selection process that is a process of determining whether or not a number can be selected. The authentication unit 107 corresponds to a part of “request receiving means” described in the claims.

  The authentication unit 107 receives user ID information stored in an IC card or the like from the authentication control device 2 as a personal authentication process, and the received user ID information is registered in advance and registered users recorded in the HDD or the like. It is determined whether or not it matches any of the ID information. That is, it is determined whether or not the user ID information received from the authentication control device 2 is registered in the server device 1.

When it is determined that the user ID information is registered in the server device 1, the authentication unit 107 performs an outlet selection process. That is, the authentication unit 107 accepts the outlet number information from the authentication control device 2 as the outlet selection process, and determines whether or not the accepted outlet number can be selected. Note that the authentication unit 107 determines that the accepted outlet number can be selected when the following conditions A and B are satisfied, for example.

Condition A: The section corresponding to the accepted outlet number is not in use. Condition B: No reservation is made for another user in the section corresponding to the accepted outlet number. When it is determined that the number can be selected, it is a functional unit that determines whether or not a supply permission condition that is a condition for permitting a predetermined power supply is satisfied. The permission determination unit 108 corresponds to “permission determination means” described in the claims.

  Specifically, the permission determination unit 108 determines whether the supply permission depends on whether the charging number NA obtained by the charging number calculation unit 105 is equal to or less than a preset number threshold Nth (for example, 10). Determine whether the condition is met. Further, it is determined whether or not the supply permission condition is satisfied, depending on whether or not the charging power WA obtained by the charging power calculation unit 106 is equal to or less than a preset power threshold Wth (for example, 300 kW). Here, the permission determination unit 108 supplies power when the charging number NA is equal to or smaller than the number threshold Nth (here, 10) and the charging power WA is equal to or smaller than the power threshold Wth (here, 300 kW). It is determined that the permission condition is satisfied.

  When the authentication unit 107 determines that the outlet number can be selected and the permission determination unit 108 determines that the supply permission condition is satisfied, the permission instruction unit 109 loads the vehicle on the vehicle corresponding to the outlet number. Charging of the stored storage battery is started. The permission determination unit 108 stores the IP address information assigned to the relay controller 3 corresponding to the outlet number in the HDD or the like of the server device 1 and corresponding to the outlet number being charged. The data is recorded in a storage unit (for example, “charging address storage unit” not shown). On the other hand, when the authentication unit 107 determines that the outlet number can be selected, and the permission determination unit 108 determines that the supply permission condition is not satisfied, the permission determination unit 108 determines that the relay controller corresponding to the outlet number. 3 is formed in the HDD of the server apparatus 1 and stores the IP address information corresponding to the outlet number waiting for charging (for example, “charging waiting address storing unit” not shown). ).

  In this way, when a charging request indicating that charging of the storage battery mounted on the vehicle is desired is received from the user, the charging number NA, which is the number of relay controllers 3 corresponding to the outlet number being charged, is obtained. In accordance with whether or not the charging number NA is equal to or less than a preset number threshold value Nth, it is determined whether or not a supply permission condition that is a condition for permitting power supply is satisfied. It is possible to appropriately determine whether or not power supply is permitted.

  In addition, when the supply of power to the outlet 6 is interrupted by the relay controller 3, the charging number NA is obtained. Therefore, it is possible to effectively use the plurality of outlets 6 provided in the power supply control system 100. it can.

That is, when a charge request indicating that the user wants to charge the storage battery mounted on the vehicle is accepted and the charged number NA is larger than the number threshold value Nth, it is determined that the supply permission condition is not satisfied, and the vehicle It is not possible to start charging the storage battery installed in the. Thereafter, when the supply of power is interrupted by the relay controller 3, the charged number NA is obtained. Therefore, it is determined that the obtained charged number NA is equal to or less than the number threshold value Nth, and the storage battery mounted on the vehicle is supplied to the storage battery. Since charging can be started, a plurality of outlets 6 arranged in the power supply control system 100 can be used effectively.

  Furthermore, when a charge request indicating that the user wants to charge the storage battery mounted on the vehicle is received from the user, a charging power WA that is the sum of the power values supplied from each commercial power source to each storage battery is obtained, Depending on whether or not the charging power WA is equal to or less than the power threshold Wth, it is determined whether or not a supply permission condition that is a condition for permitting the supply of power is satisfied. can do.

  In addition, when the supply of power to the outlet 6 is interrupted by the relay controller 3, the charging power WA that is the sum of the power values supplied from each commercial power source to each storage battery is obtained. A plurality of outlets 6 arranged in 100 can be used effectively.

  That is, when a charge request for charging a storage battery mounted on a vehicle is received from a user and the charging power WA is greater than the power threshold Wth, it is determined that the supply permission condition is not satisfied, and the vehicle It is not possible to start charging the storage battery installed in the. After that, when the supply to the outlet 6 is interrupted by the relay controller 3, the charging power WA is obtained. Therefore, it is determined that the obtained charging power WA is equal to or less than the power threshold value Wth, and the storage battery mounted on the vehicle Since there is a high possibility that charging can be started, the plurality of outlets 100 arranged in the power supply control system 100 can be used effectively.

  In the present embodiment, a case will be described in which the permission determination unit 108 determines whether to permit power supply based on the charge number NA and the charge power WA. However, the permission determination unit 108 determines whether the charge number NA Or the form which determines whether supply of electric power is permitted based on charging electric power WA may be sufficient. In this case, the process is simplified.

  Whether permission determination unit 108 permits (or in addition to) charging power WA to supply power based on charging current AM that is the sum of current values supplied from each commercial power source to each storage battery. The form which determines whether or not may be sufficient.

  In step S115, a power supply permission / refusal determination process (see FIG. 14) for determining whether or not power supply to the outlet 6 corresponding to the outlet number received in step S109 is permitted. In step S117, the permission instructing unit 109 determines whether the determination result in step S115 is permission to supply power to the outlet 6 or not. If YES in step S115 (when power supply to outlet 6 is permitted), the process proceeds to step S119. If NO in step S115 (when power supply to outlet 6 is rejected), the process proceeds to step S123 in FIG.

  In step S119, the permission instruction unit 109 reads the IP address information corresponding to the outlet number received in step S109 from the “address storage unit” formed in the HDD or the like. In step S121 (corresponding to step T15 in FIG. 9), the permission instruction unit 109 gives the IP address information read in step S121 to the outlet 6 corresponding to the outlet number received in step S109.

Then, the process proceeds to step S129 in FIG.

  In step S123 of the flowchart illustrated in FIG. 13, the permission determination unit 108 increments the “waiting number”, which is the number of vehicles waiting to be charged, by “1”. In step S <b> 125, the permission determination unit 108 transmits instruction information to the authentication control device 2 to display information indicating that charging is waiting to be started (waiting). Next, in step S127, the permission determination unit 108 associates the outlet number received in step S109 and the IP address information corresponding to the outlet number, and records them in the “charging waiting address storage unit”.

  Next, in step S129 (corresponding to step T16 in FIG. 9), the power reception unit 101 receives power information from each relay controller 3 corresponding to each outlet 6 being charged via the authentication control device 2. . In step S131, the full charge determination unit 102 determines whether or not the storage battery of the vehicle connected to each outlet 6 is in a fully charged state. If YES in step S131, the process proceeds to step S133. If NO in step S133, the process returns to step S101 in FIG.

In step S <b> 133, the full charge determination unit 102 transmits a mail indicating that the battery is fully charged to the user's mobile phone 7. In step S135, the interruption determination unit 103 reads out the IP address information corresponding to the outlet number determined to be fully charged in step S131 from the “charging address storage unit”, and the “charging address storage unit” The outlet number information and the IP address information stored in “” are deleted. Next, in step S137 (corresponding to step T17 in FIG. 9), the blocking instruction unit 104 gives the IP address information read in step S135, and sets the outlet number determined to be fully charged in step S131. Instruction information (shutoff instruction information) for interrupting power supply to the corresponding outlet 6 is generated and transmitted to the relay controller 3 via the authentication control device 2. In step S139, the permission determination unit 108 determines whether the “waiting number” is “1” or more. In the case of YES in step S139 (when the “waiting number” is “1” or more), the process proceeds to step S141. If NO in step S139 (if "Waiting number" is "0"), the process returns to step S101 in FIG.

  In step S141, a power supply permission / inhibition determination process for determining permission / inhibition of power supply to the outlet 6 corresponding to the outlet number stored at the head of the “charging waiting address storage unit” (the oldest stored timing) (see FIG. 14). ) Is executed. In step S143, the permission instruction unit 109 determines whether the determination result in step S141 is permission to supply power to the outlet 6 or not. If YES in step S143 (when power supply to outlet 6 is permitted), the process proceeds to step S145. If NO in step S143 (when power supply to outlet 6 is rejected), the process returns to step S101 in FIG.

  In step S145, the permission instruction unit 109 reads out IP address information corresponding to the outlet number stored at the head of the “charge waiting address storage unit”. In step S147 (corresponding to step T15 in FIG. 9), the IP address information read in step S145 is given by the permission instruction unit 109, and the outlet corresponding to the outlet number for which power supply is permitted in step S143. 6 is generated and transmitted to the relay controller 3 via the authentication control device 2. Further, the permission instruction unit 109 records the outlet number information and the IP address information stored in the “charging waiting address storage unit” in the “charging address storage unit”. The outlet number information and the IP address information recorded in the “charging address storage unit” are deleted from the “charging waiting address storage unit” by the permission instruction unit 109. In step S149, the permission determining unit 108 decrements the “waiting number”, which is the number of vehicles waiting to be charged, by “1”, and the process returns to step S101 in FIG.

  FIG. 14 is a detailed flowchart showing an example of the power supply permission / refusal determination process executed in step S115 of FIG. 12 and step S141 of FIG. First, in step S 151, the number of relay controllers 3 being charged is counted by counting the number of outlet number information (or IP address information) stored in the “charging address storage unit” by the charging number calculation unit 105. A certain charged number NA is required. Next, in step S153, the permission determination unit 108 determines whether or not the charged number NA obtained in step S151 is equal to or less than the number threshold Nth (for example, 10). If YES in step S153, the process proceeds to step S155. If NO in step S153, the process proceeds to step S163.

In step S155, the power receiving unit 101 receives power value information from each relay controller 3 corresponding to the outlet number information (or IP address information) stored in the “charging address storage unit”. In step S157, the charging power calculation unit 106 obtains the charging power WA that is the sum of the power values received in step S155. Next, in step S159, the permission determination unit 108 determines whether or not the charging power WA obtained in step S157 is equal to or less than a power threshold value Wth (for example, 300 kW). If YES in step S159, the process proceeds to step S161. If NO in step S159, the process proceeds to step S163.

  In step S161, the permission determination unit 108 permits the start of power feeding, and the process returns. In step S163, the permission determination unit 108 rejects the start of power supply and returns the process.

  In this way, the relay controller 3 that controls the supply and cut-off of power for each outlet 6 determines whether the IP address information matches, and the power supply to the relay 4 and the relay 4. Since it is only necessary to provide the opening / closing unit 302 for instructing the interruption, the device (relay controller 3) for controlling the supply and interruption of power for each outlet 6 can be configured simply.
