Description

  The present invention relates to a power usage permission / refusal determination system. Specifically, the present invention relates to a power usage permission determination system that determines whether power is permitted or not by controlling a switching device that switches whether power supply is installed indoors.

  In general, there are a method of stopping power supply at the end of a power use contract at the time of moving home, a method of disconnecting a watt hour meter, and a method of turning off an indoor breaker. Of the two methods, the method of turning off the indoor breaker is the mainstream from the viewpoints of convenience for the next power consumer and ease of construction by the contractor.

  If the indoor breaker is turned off due to the termination of the power usage contract, the next power consumer will be able to use power by turning the indoor breaker on. it can. However, since the power consumer can use the power by simply turning the indoor breaker “on”, the power consumer can use the power without permission from the power company. There was a problem that it could be used.

  Therefore, in the past, an energy use authentication system has been proposed in which an authentication procedure related to an energy use contract is performed between an energy supplier (electric power consumer, etc.) and an energy supplier (electric power supplier, for example, an electric power company). (Patent Document 1).

  The authentication system proposed in Patent Document 1 is provided at an energy supply destination, and an energy supply source (such as an indoor breaker) for supplying energy from the energy supply source to the energy supply destination, and an energy supply provided at the energy supply destination And a management server that manages an energy usage contract for each energy supply destination provided in the energy supply source. In this authentication system, when authentication information or the like is input to the authentication device, the management server authenticates the validity of the input authentication information, and an energy supply destination is transmitted by a signal transmitted by the management server according to the authentication result. Control the energy source.

JP 2006-172396 A

  However, the authentication system proposed in Patent Document 1 requires that an energy supply destination and an energy supply source are connected via a network. Therefore, when starting to use electric power at the energy supply destination, if it is not possible to connect to the energy supply source via the network due to a network device failure, etc., the authentication procedure between the energy supply destination and the energy supply source cannot be performed, There is a problem that the energy supplier cannot use electric power.

  Therefore, an object of the present invention is to provide a power usage permission / rejection determination system capable of determining power usage permission / rejection without a power consumer and a power supply source being connected via a network.

A code is stored, and the permission control means permits the switching by the switching device when the collation matches, and when the collation does not match and when the authentication code is not stored in the storage means The present invention relates to a power use permission / rejection determination system characterized in that the switching by the switching device is not permitted.

  According to the configuration of (1), the setting device arranged near or inside the watt hour meter provided outdoors accepts the setting of the authentication code by the authentication code setting means, and the authentication code setting means by the transmission means The authentication code received by is transmitted to the receiving means of the switching control device. On the other hand, the switching control device arranged on the distribution board provided indoors receives the authentication code from the transmission means of the setting device by the receiving means, and stores the authentication code received by the receiving means by the storage means. . Then, the switching control device accepts the input of the authentication code by the input means, collates the authentication code input to the input means by the verification means and the authentication code stored in the storage means, and by the permission control means, If the verification matches, the switching device is allowed to switch the power supply from the power supply source, and if the verification does not match or the authentication code is not stored in the storage means, the switching device is allowed to switch. First, it controls whether or not switching is performed by the switching device.

  By doing in this way, the switching apparatus by an authentication code can be controlled by the setting apparatus provided outdoors and the switching control apparatus provided indoors. For this reason, it is possible to determine whether or not to use power without connecting the power consumer and the power supply source via the network.

  Hereinafter, a preferred embodiment of the power usage permission / inhibition determination system 1 of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an overall configuration of a power use permission / rejection determination system 1 according to an embodiment of the present invention. The power use permission / refusal determination system 1 controls a switching device that switches whether power supply from a power supply source (for example, a power company) is permitted, and determines whether or not a consumer uses power. The power use permission / refusal determination system 1 includes a watt-hour meter 200 provided in the outdoor 5, a setting device 20 disposed in the watt-hour meter 200 in the outdoor 5, a distribution board 100 provided in the indoor 6, The switching control device 10 disposed on the distribution board 100 in the indoor 6 and the breaker 101 as the switching device disposed on the distribution board 100 in the indoor 6 are provided. The setting device 20 may be disposed in the vicinity of the watt-hour meter 200.

  The reason why the setting device 20 is arranged in the vicinity of or inside the watt-hour meter 200 is for convenience when the person who supplies the power operates the setting device 20. That is, the power supply person sets the authentication code used by the switching control device 10 that controls the breaker 101 at the setting device 20 when reading the amount of power used recorded in the watt-hour meter 200. can do. In addition, the reason why the switching control device 10 is arranged on the distribution board 100 is that it is arranged near the breaker 101 operated by an electric power consumer (hereinafter simply referred to as a consumer) in order to use electric power. This is because the switching control device 10 can be operated without being confused.

  The switching control device 10 and the setting device 20 are connected via a communication line, and transmit and receive data and signals between them. The switching control device 10 and the breaker 101 are also connected via a communication line, and transmit and receive data and signals between them. As the communication line, for example, a power line using power line carrier communication technology can be used.

  The distribution board 100 is provided in the indoor 6 and is a facility for supplying electricity to each part of the indoor 6. The distribution board 100 includes a breaker 101 that functions as a switch for controlling the supply of electricity to the indoor 6, a switch for operating electrical equipment, a fuse board 102 that integrates instruments, fuses, terminals, and the like. The

  The breaker 101 is an amper breaker provided in the distribution board 100. Breaker 101 is connected to watt-hour meter 200. Electric power is supplied to the breaker 101 via a watt-hour meter 200 connected to a lead-in line (not shown) drawn from a utility pole or the like. An operation handle (not shown) is provided on the front surface of the breaker 101. By setting the operation handle to the “ON” side or the “OFF” side, the electric circuit can be opened and closed to control whether electric power can be supplied to the indoor 6 from the power supply source.

  Specifically, when the operation handle of the breaker 101 is set to the “on” side, the electric circuit is closed and power is supplied to the indoor 6 from the power supply source, and when the operation handle of the breaker 101 is set to the “off” side, the electric circuit is It opens and no power is supplied to the indoor 6 from the power supply source. Hereinafter, setting the operation handle to the “ON” side is referred to as setting the breaker 101 to “ON” or switching to “ON”. Setting the operating handle to the “OFF” side refers to setting the breaker 101 to “OFF” or switching to “OFF”.

  The breaker 101 according to an embodiment of the present invention plays a role of a switch that controls the supply of electricity to the indoor 6 and is controlled by the switching control device 10. Specifically, the switching control device 10 controls the switching of the breaker 101 between “ON” and “OFF”, and when the switching control device 10 permits switching, the breaker 101 can be set to “ON”. .

  The watt-hour meter 200 is provided in the outdoor 5 and measures and records the amount of power used in the indoor 6.

  The setting device 20 is a device that sets an authentication code used in the switching control device 10 that controls the breaker 101. Here, the authentication code is a kind of password for switching between “ON” and “OFF” of the breaker 101, and is composed of alphabets, numbers, symbols, or a mixture thereof. The setting device 20 includes an authentication code setting unit 21 and a transmission unit 22.

  The authentication code setting means 21 accepts the setting of the authentication code or the deletion of the authentication code from the operator of the setting device 20. The authentication code setting means 21 is specifically a keyboard or a numeric keypad, for example. The authentication code is a numeric string when the power supply source is arbitrarily determined and the authentication code setting means 21 is a numeric keypad. Here, erasing the authentication code means erasing the authentication code stored in the storage unit 12 of the switching control device 10. For example, when the authentication code setting unit 21 is a numeric keypad, the authentication code setting unit 21 determines whether the authentication code setting unit 21 has received a predetermined numeric string that is previously input for deleting the authentication code. Accept erasure.

  The transmission unit 22 transmits the authentication code received by the authentication code setting unit 21 to the switching control device 10. Further, the transmission unit 22 transmits the deletion of the authentication code received by the authentication code setting unit 21 to the reception unit 11 of the switching control device 10 as an authentication code deletion signal. Communication between the transmission unit 22 and the reception unit 11 may be wired communication or wireless communication.

  In this way, by setting the authentication code with the setting device 20 installed outdoors 5, the setting of the authentication code used in the switching control device 10 that controls the breaker 101 in the indoor 6 can be made by the person who is the power supply source. Can be easily done.

  The switching control device 10 controls switching of the breaker 101 between “ON” and “OFF”, and manages an authentication code used for the ON / OFF control of the breaker 101. The switching control device 10 includes a receiving unit 11, a storage unit 12, an input unit 13, a verification unit 14, a permission / refusal control unit 15, and an erasing unit 16.

  The reception unit 11 receives the authentication code from the transmission unit 22 of the setting device 20 and passes the authentication code to the storage unit 12. In addition, the erasing signal is received from the transmission unit 22 of the setting device 20, and the erasing signal is transferred to the erasing unit 16.

  The storage unit 12 stores the authentication code in response to the reception unit 11 receiving the authentication code. That is, the storage unit 12 stores the authentication code in response to the delivery of the authentication code from the receiving unit 11. If the storage unit 12 has already stored the authentication code, the stored authentication code is updated to the authentication code passed by the receiving unit 11. The authentication code stored in the storage unit 12 is referred to when collating with the authentication code input to the input unit 13 by the collating unit 14 described later. Further, in response to the reception means 11 receiving the erasure signal, the authentication code stored in the storage means 12 is erased by the erasure means 16 described later.

  The input means 13 accepts an input of an authentication code used for controlling switching of “ON” and “OFF” of the breaker 101 from an operator of the switching control device 10. Specifically, the input means 13 is, for example, a keyboard or a numeric keypad. Here, the operator of the switching control device 10 is a consumer who uses electric power indoors 6. The correct authentication code input to the input means 13 is notified from the power supply source when the consumer makes a power use contract with the power supply source.

  The collation unit 14 collates whether or not the authentication code input by the consumer using the input unit 13 matches the authentication code stored in the storage unit 12. The collated result is transferred to the permission / refusal control means 15.

  Further, the collating unit 14 may count the case where the collation does not match as a result of the collation, and may instruct the input unit 13 not to accept the authentication code input when the collation does not match for a predetermined number of times. .

  The permission / refusal control means 15 controls permission / inhibition of switching between “ON” and “OFF” of the breaker 101 in accordance with the verification result of the verification means 14. Specifically, the permission / refusal control means 15 transmits a signal permitting the breaker 101 to be switched to “ON” to the breaker 101 in response to the result that the matching is matched from the matching means 14. To do. When the breaker 101 receives a signal permitting switching of the breaker 101 to “ON”, the breaker 101 is unlocked and the consumer can set the breaker 101 to “ON”.

  Here, the lock of the breaker 101 is a state in which the customer cannot perform an “on” or “off” operation of the breaker 101. Specifically, it is a state where the operation handle of the breaker 101 cannot be operated, or a state where “ON” and “OFF” of the breaker 101 are not switched even if the operation handle of the breaker 101 is operated. The breaker 101 is locked when the authentication code setting means 21 of the setting device 20 receives the authentication code. Details will be described later.

  On the other hand, the permission / refusal control unit 15 switches the breaker 101 to “ON” when a result indicating that the verification does not match is received from the verification unit 14 or when the authentication code is not stored in the storage unit 12. A signal that does not permit this is transmitted to the breaker 101. The breaker 101 does not release the lock of the breaker 101 when it receives a signal that does not permit switching the breaker 101 to “ON”. The permission / refusal control unit 15 switches the breaker 101 to “ON” when a result indicating that the verification does not match is received from the verification unit 14 or when the authentication code is not stored in the storage unit 12. A signal that does not permit this need not be transmitted to the breaker 101.

  Thus, unless the correct authentication code is input to the input means 13, the consumer cannot turn on the breaker 101. That is, a consumer who does not obtain a correct authentication code without making a power usage contract with a power supply source cannot use power. As a result, unauthorized use of power can be prevented. Furthermore, by preventing unauthorized use of electric power, the trouble of investigating unauthorized use of electric power is eliminated.

  When the erasing signal is received from the receiving unit 11, the erasing unit 16 erases the authentication code stored in the storage unit 12. Further, when the erasing signal is received from the receiving unit 11, the erasing unit 16 switches the breaker 101 to “OFF” and transmits a signal to the breaker 101 to instruct to lock the breaker 101. When the breaker 101 switches the breaker 101 to “OFF” and receives a signal to lock the breaker 101, the breaker 101 turns “OFF” and locks. If the breaker 101 is already “OFF”, only the lock is performed.

  Since the breaker 101 can be locked in this manner, the unauthorized use of power can be prevented without disconnecting the watt hour meter or the like at the end of the power usage contract. Moreover, since the watt hour meter or the like is not disconnected, the construction time at the end of the contract can be shortened.

  Note that the switching control device 10 may be provided with a warning unit, and a warning may be given to the consumer by the warning unit according to the collation result of the collation unit 14. Specifically, the warning unit may give a warning to the consumer to the effect that the result of the verification does not match is received from the verification unit 14. Specifically, the warning means is a speaker, a liquid crystal display, or the like, and notifies the consumer that the authentication code is incorrect by using an error sound or an error message.
