Description

  The present invention provides a storage means for storing registered password information, and a password information determination for determining whether the password information input by the information input means matches the registered password information stored in the storage means. The present invention relates to an authentication apparatus provided with an information processing means for executing processing, and a grid-connected power supply facility including the authentication apparatus.

  The authentication apparatus configured as described above determines whether or not the input password information matches the registered password information stored in the storage means when the password information is input by the information input means. In order to authenticate whether or not the operator who has input the personal identification information by the information input means is a legitimate operator, such an authentication device is conventionally configured as follows. There was a thing.

  That is, apart from the information input means for inputting the password information, a fingerprint reading means for reading a fingerprint of a person's finger operating the information input means is provided, and the input password information does not match the registered password information. If the fingerprint of the operator is read and matches the pre-registered fingerprint, it is determined that the operator is a legitimate operator, and a password that is different from the registered password stored in the storage means is registered. As a state in which it can be input (see, for example, Patent Document 1) (first conventional example).

  Further, as another conventional example, in addition to the information input means for inputting a personal identification number as the personal identification information, an iris state reading means for reading an iris state of a person who operates the information input means is provided. Even if the password information does not match the registered password information, it reads the iris state of the eye of the operator, and when the iris state matches the pre-registered iris information, it is a legitimate operator. There is a configuration in which it is determined that a password that is different from the registered password stored in the storage unit can be input as the registered password, for example (see, for example, Patent Document 2). (Second conventional example).

  In both the first conventional example and the second conventional example, the authentication device as described above is such that the operator forgets the registered password information or the registered password information needs to be changed. In some cases, legitimate operations are performed by reading the fingerprints of the fingers and the iris of the eyes, which are the physical characteristics of the human being to identify the individual, and comparing them with the pre-registered fingerprint and iris information. It is possible to update the registration identification information when it is determined whether the user is a legitimate operator, and to update the personal identification information.

Japanese Patent Laid-Open No. 9-297845 JP-A-9-259197

  The conventional configuration as described above can forget the password information as described above by checking with the fingerprints of the fingers and the iris of the eyes, which are human physical characteristics for identifying the individual. The password information can be updated by confirming that the operator is a legitimate operator. However, in the above-described conventional configuration, the fingerprint reader or iris for reading the fingerprint is used. It is necessary to provide a special device for discriminating physical characteristics such as an iris reader for reading the state, and such a device is complicated and expensive, so that the authentication device is expensive. However, it is not suitable for use in a grid-connected power supply facility or the like, which is a housing equipment installed in a general household.

  Therefore, it can be suitably used in housing equipment installed in a general household as described above, and when the operator forgets the registered password information or when the registered password information needs to be changed. Therefore, an authentication device that can update the registered personal identification number has been desired.

  The object of the present invention can be suitably used in housing equipment and the like installed in a general household, and when the operator forgets the registered password information or when the registered password information needs to be changed. The present invention provides an authentication device capable of updating the registration identification information, and a grid-connected power supply facility including the authentication device.

The authentication device according to the present invention determines whether or not the storage means for storing the registered password information and the registered password information stored in the storage means match the password information input by the information input means. And an information processing means for executing a personal identification information determination process,
The first characteristic configuration is that the information processing unit repeats when the information input unit repeatedly inputs password information that does not match the registered password information in the password information determination process. It is configured to determine whether or not the input content of the password information that does not match the registered password information is in accordance with an update rule, and is repeatedly input by the information input means in the password information determination processing When it is determined that the input content of the password information that does not match the registered password information conforms to the update rules, the input of the password information that does not match the registered password information repeatedly input by the information input means Registration information for obtaining registered password information based on the contents and the update rules, and storing the obtained registered password information as new registered password information in the storage means And it is configured to perform a new process, the information processing means, a switchable to a plurality of types of update rules, each of the set time elapses, to switch to a different update rules until it It is in the point which is comprised.

  According to the first characteristic configuration, when the password information is input by the information input means, the information processing means determines whether or not the input password information is registered password information stored in the storage means. A password information discrimination process is executed. At this time, for example, even if a legitimate operator has forgotten the password information, the input password information is different from the registered password information, so the input password information and the registered password information match. It will be determined that it is not.

The information processing means is repeatedly input by the information input means when the information input means repeatedly inputs password information that does not match the registered password information in the password information determination process . It is determined whether or not the input content of the password information that does not match the registered password information conforms to the update rules. In other words, even when password information different from the registered password information is entered, if the password information that does not match the registered password information is repeatedly input in accordance with the update rules, the input contents are in accordance with the update rules. It will be determined.

If it is determined that the input content of the password information that does not match the registered password information conforms to the update rules, the information processing means executes the registered information update process. That is, the information processing means obtains the registered password information based on the input contents of the password information that is repeatedly input by the information input means and does not match the registered password information and the update rules, and newly determines the obtained registered password information. It is stored in the storage means as the registered password information.

  And when such an authentication device is used for a home equipment installed in a general home and is provided to authenticate whether or not the operator is an authorized user of the home equipment In this case, if it is determined that the entered personal identification information and the registered personal identification information do not match, the operator makes an inquiry to the management center managed by the installation operator who installs the household equipment. .

  Therefore, the management center managed by the installation company confirms whether the operator who has inquired is an authorized user based on information such as name and date of birth. If it is confirmed that the user is an authorized person, the update rules in the authentication device are informed so that the operator repeatedly enters the password information in a state in accordance with the update rules. Information can be stored in the storage means. In the case where it is used for housing equipment installed in a general household, it is possible to ensure the reliability of authentication in this way.

  Therefore, it can be suitably used in household equipment installed in general households, and when the operator forgets the registered password information or when the registered password information needs to be changed, An authentication device that can update the registered identification information can be provided.

In addition, since the information processing means can be switched to a plurality of types of update rules, when a predetermined condition is satisfied from a state where one of the plurality of types of update rules is set, If you switch to an update rule that is different from the update rule that was previously set, the reliability during authentication will be improved compared to the update rule that is always fixed in the same state. Can do.

  The predetermined condition is, for example, a configuration in which switching is automatically made to an update rule every time a set time elapses, or a switching command is sent from a management device communicably connected to the authentication device via communication means. The structure etc. which command can be considered.

In particular, according to the first feature configuration, every time the set time elapses, the rule is automatically switched to a different update rule. As the set time, various times such as one month, one week, and one day can be set. Therefore, since the update rule automatically switches over time, for example, compared to a configuration in which a switching command is instructed by an artificial input operation, the update rule is accurately updated without forgetting the operation. Therefore, the reliability as the authentication device can be further improved.

The second characteristic configuration of the present invention, in addition to the first feature configuration, the storage means is configured to store the registered personal identification information in association with the operator identification information, said information processing means, said In the personal identification information discrimination process, based on the operator identification information and the personal identification information input by the information input unit, the input personal identification information is stored in the storage unit and corresponds to the operator identification information. It is configured to determine whether or not the registered personal identification information matches.

According to the second feature configuration, the registered password information is stored in the storage means in a state associated with the operator identification information. When performing authentication, the operator adds the password information to the password information by the information input means. Thus, operator identification information is input. The information processing means is stored in the input password information and the storage means based on the operator identification information and the password information input by the information input means in the password information determination process; It is determined whether or not the registered personal identification information corresponding to the operator identification information matches.

  As a result, for example, even when there are a plurality of operators who operate the information input unit, if different operator identification information is set for each of the plurality of operators, a plurality of operators are stored in the storage unit. A plurality of registered password information is stored in a state associated with the operator identification information. When a plurality of operators operate the information input means, the operator identification information set for the user and the personal identification information are input. Then, the information processing means determines whether or not the input password information matches the registered password information stored in the storage means and corresponding to the operator identification information. It is possible to authenticate whether or not the user is a legitimate operator.

  Therefore, even when there are a plurality of operators who operate the information input means, it is possible to perform the authentication effectively, and the operator stores the password information that the operator can easily remember as the registered password information. There is also an advantage that it is possible to make the password information as difficult to forget as possible.

The third characteristic configuration of the present invention is a grid-connected power plant equipped with the power generation capable of generating device the power consumed by the interconnection to and facilities to the commercial power system, according to claim 1 or 2 The information processing unit is provided with an identification determination timing for identifying whether the user of the facility is a new user who newly operates the power supply facility. Prior to the password information determination process, an input prompting process for prompting the user to input the password information is executed. In the password information determination process, the password information input by the information input means is When it is determined that the information does not match the registered personal identification information, a guidance information output process for outputting procedure guidance information for guiding that the grid connection procedure of the power generator is performed is executed.

According to the third characteristic configuration, the information processing unit is at an identification determination timing for identifying whether or not the user of the facility is a new user who newly operates the power supply facility. An input prompting process for prompting the user of the facility to input the personal identification information is executed, and then the personal identification information determination process is executed. In other words, since the user of the facility is prompted to input the password information by the input prompting process, the information input means tries to input the password information. At that time, if the user is a new user who operates the power supply facility, Since the registered password registered in the means is not known, a different password is entered. When the information processing means determines that the personal identification information input by the information input means does not match the registered personal identification information, guidance information for outputting procedure guidance information for guiding that the grid connection procedure of the power generator is performed. Execute output processing.

  In other words, the grid-connected power supply system configured as described above is connected to a commercial power system managed by an electric power company, for example, to meet the demand for power required for a residence in a general household as the facility. On the other hand, it is configured to be used in a power supply state in which both power supply by the power generator and power supply by the commercial power system can be performed (such a state is referred to as an operation state by grid connection), When such a power supply facility is installed in the facility and operated in the operating state by the grid connection, the power supply facility is operated by the grid connection based on an application from a user who uses the power supply facility. It is necessary to carry out grid interconnection procedures to obtain permission from the electric power company for operation in the state.

  Not only when the power supply equipment is newly installed, but also when the user changes his or her home after moving, etc., and the user changes, the new user can connect the power supply equipment to the grid connection. When operating in an operating state, it is necessary to newly perform the grid interconnection procedure with an electric power company. However, since it is generally not well known about the operation by grid interconnection as described above, the new user does not recognize that it is necessary to perform such grid interconnection procedure There are many.

  Therefore, when it is determined that the password information input by the information input means does not match the registered password information by using the authentication device, the procedure guide information for guiding that the grid connection procedure of the power generator is performed is output as information. By outputting by means, it is possible to prompt a new user to perform the grid connection procedure.

According to a fourth feature configuration of the present invention, in addition to the third feature configuration, an operation management unit that manages the operation of the power generation device includes: a determination result of the password information determination process by the information processing unit; and a registration information update process. Based on the processing result, when the entered personal identification information and the registered personal identification information coincide with each other and when new registration personal identification information is stored in the storage means, the operation start command is instructed thereafter. When the operation of the power generation apparatus is executed and the input personal identification information and the registered personal identification information do not match, the power generation apparatus is maintained in the operation stop state thereafter.

According to the fourth feature configuration, the operation management means for managing the operation of the power generation device has determined that the password information and the registered password information input by the password information determination processing by the information processing means match. And when the said registration information update process is performed and new registration password information is memorize | stored in the memory | storage means, if an operation start command is instruct | indicated after that, operation | movement of an electric power generating device will be performed. Thus, and when the personal identification information entered with the registered personal identification information is determined to match the personal identification information judging processing, the new registration personal identification information the registration information update processing is performed is stored in the storage means In such a case, since the grid interconnection procedure as described above has been completed, the operation of the power generator can be executed.

  On the other hand, when the password information input by the information input means does not match the registered password information, the facility user is a new user who newly operates the power supply equipment, and the grid interconnection as described above Since the procedure is not performed, the power generation apparatus is maintained in the operation stop state thereafter. Therefore, it is possible to prevent the new user from operating the power supply facility in the operation state by the grid interconnection without performing the grid interconnection procedure.

Is registered in the memory 34 as new registered password information.

  Furthermore, the information processing means 100 precedes the personal identification information determination process as the identification determination timing for identifying whether or not the facility user is a new user who newly operates the equipment. The password prompting process for prompting the user to input the password information is executed, and the password information input by the information input means matches the registered password information in the password information determination process. When it is determined not to do so, it is configured to execute guide information output processing for outputting procedure guide information for guiding that the grid connection procedure of the power generator is performed.

Hereinafter, a specific configuration of the authentication device H will be described.
As shown in FIG. 2, a remote control device R1 for providing various commands to the operation control unit 7 by human operation is provided. The remote control device R1 includes a plurality of operation keys and the operation keys. The information input operation unit J that can input numeric information and the like, and various information such as information when operating the operation keys and other instruction information are displayed and output in a state that the user can visually recognize. An information display unit G as information output means is provided, so that the operator can input a personal identification number. A non-volatile memory 34 for storing a registered password is provided based on a command from the operation control unit 7.

  The information processing means 100 is configured using the configuration of control processing in the operation control unit 7. That is, the operation control unit 7 is configured to execute the password information determination process and the registration information update process as described above based on information input from the information input operation unit J. If it is determined that the entered personal identification number does not match the registered personal identification number stored in the memory 34, the procedure display information for guiding the system interconnection procedure of the cogeneration apparatus 3 is output at the information display unit G. It is configured to let you.

  In addition, the operation control unit 7 determines whether the input password information matches the registered password information based on the determination result of the password information determination process and the processing result of the registered information update process, and new registered password information. Is stored in the memory 34, the operation of the combined heat and power supply device 3 is executed when an operation start command is issued thereafter, and when the input password information and the registered password information do not coincide with each other, the thermoelectric The co-feeder 3 is configured to be kept in an operation stop state.

  Therefore, in this embodiment, the authentication device H is configured by the information input operation unit J, the memory 34, and the information processing means 100 configured by the operation control unit 7.

Next, specific control processing of the operation control unit 7 will be described with reference to a flowchart.
That is, as shown in FIG. 3, when the power supply is turned on and the power supply is started (step 1), the operation control unit 7 stores a registered personal identification number for identifying the user in the memory 34 at that time. If not, processing for setting a registered password is executed. That is, setting instruction information for setting the user's personal identification number is output to the information display unit G (steps 2 and 3). Specifically, a message “Please register your PIN” is displayed on the information display part G. The user inputs his / her personal identification number such as a 2-digit number from the information input operation unit J, for example.

  When it is determined that the password has been input and the confirmation key or the like has been operated and the input has been completed, the input password is written and stored in the memory 34 as a registered password (steps 4 and 5). Moreover, the operation | movement which produces electric power in the cogeneration apparatus 3 is permitted, and the said system can be drive | operated (step 6). In this way, if the registered password is not stored in the memory 34, the power supply equipment is initially installed, so the password corresponding to the user is registered and stored in the memory 34. Therefore, the system can be operated.

  Thereafter, it is determined whether or not a set time (24 hours) or more has elapsed since a power failure state in which the power supply from the commercial power system 9 stops (step 7). When the power outage time becomes longer than the set time (24 hours), it is assumed that the facility user has reached the identification determination timing for identifying whether or not the user is a new user who operates the equipment. The power generation operation by the co-feeder 3 is stopped so that the system cannot be used (step 8), and input prompting processing for outputting input prompting information for prompting the user to input a personal identification number from the information display unit G is executed. (Step 9). Specifically, a message “Please enter your PIN” is displayed on the information display part G.

  As a result, the user inputs his / her personal identification number from the information input operation unit J, and determines whether or not the inputted personal identification number matches the registered personal identification number stored in the memory 34 ( Step 11). If the input password and the registered password match at that time, the operation of generating power in the combined heat and power supply device 3 is permitted to enable the system to operate (step 6). When it is determined in step 11 that the entered password does not match the registered password, it is considered that the resident has been changed in the household and the user has changed. Guidance information output processing for display output at G is executed (step 12). Specifically, a message “Procedure is necessary for power generation. Please contact us” is displayed on the information display unit G.

  Therefore, when the entered password does not match the registered password, the user contacts the person in charge at the management center in the installation company of the system. Also, at that time, the installation company of the system may be a case where the user who is in contact with the equipment is a new user and cannot register his / her personal identification number, or It is confirmed whether the user has been continuously using the user from the past but has forgotten the password. For example, the person in charge at the management center confirms personal information such as name and date of birth for the person who made the inquiry, and whether the person is a continuous user or a new user It will be confirmed whether or not.

  If it is a new user, then the grid interconnection procedure as described above will be performed. Specifically, the installation company of the system performs the grid interconnection procedure with the power company on behalf of the user.

  On the other hand, if it can be confirmed that the user has been using it continuously, the update rule for updating the security code is notified, so the user can enter the contents in accordance with the update rule. You can enter your PIN with.

  When the password input that does not match the registered password is repeatedly input by the information input operation unit J, the operation control unit 7 determines that the input content of the password that has been repeatedly input is the update rule. It is determined whether or not it complies. In this embodiment, when the same personal identification number is input three times in succession, it is determined that it conforms to the update rules (step 13). For example, when the operator inputs “37” as the personal identification number and operates the confirmation key or the like, if the personal identification number does not match the registered personal identification number, the operator is prompted again to enter the personal identification number. Re-enters “37” as the password and operates the confirmation key and the like. However, since it does not match the registered password, the user is prompted again for the password. When the operator inputs “37” as the personal identification number and operates the confirmation key or the like, it is determined that the same personal identification number is input three times in succession and the input contents comply with the update rules. Will do. Therefore, Step 11 and Step 13 correspond to the password information determination process.

  When it is determined in step 13 that the input content of the personal identification number is an input content complying with the update rules, the registration information update process is executed (step 14). That is, a new registered personal identification number “37” based on the input contents of the personal identification number repeatedly input (the number “37” in the above example) and the update rule (enter the same number three times in the above example). The new registered password is updated and stored in place of the registered password stored in the memory 34. After the registration identification number is updated in this way, the operation in the grid connection state as described above is permitted, and the cogeneration apparatus 3 can be operated (step 6).

  If the operator who entered the security code is a new user, proceed with the grid connection procedure as described above, and set various operating conditions to correspond to the usage form by the new user by the installer. Until the initial setting of the operation state to be completed is completed, the state in which the combined heat and power supply device 3 is stopped is continued. After the initial setting of the operation state is completed, the installation company of the equipment notifies the update rule for updating the registered password, and the password is entered with the input contents in accordance with the update rule. It becomes possible to input a number.

[Second Embodiment]
Next, 2nd Embodiment of this invention is described based on drawing.
In the second embodiment, the other configurations that differ in the processing configuration by the information processing means are the same as those in the first embodiment, so only the different configurations will be described here, and the description of the same configurations will be omitted.

  In this embodiment, the information processing means 100 is configured to be switchable to a plurality of types of update rules, and is configured to switch to a different update rule every time the set time elapses. .

That is, the operation control unit 7 constituting the information processing means 100 is configured to be switchable to a plurality of types of update rules, and executes control as shown in FIG.
Since the processing from step 1 to step 7 and the processing from step 8 to step 12 in FIG. 4 are the same as in the first embodiment, the description thereof will be omitted, but in this embodiment, the set time elapses. Each time the update rule is switched to another one (steps 15 and 16). In step 13, it is determined whether or not the input content to the information input operation unit J conforms to the update rules set at that time.

  In addition, since the installation company of the power supply equipment knows the elapsed time since the installation of the equipment, for example, when a continuation user who has forgotten the security code contacts, it recognizes which update rule is currently in use It can be done. The set time can be set and executed as appropriate, for example, one day or one week (7 days).

As a plurality of types of update rules, for example, three types of update rules will be described as an example.
For example, the first rule is the same as that described in the first embodiment, and the second update rule is configured to repeatedly input the same password three times every other time. An example of a rule is to enter the same number three times and then enter a different number three times. When the explanation is added, the second update rule is, for example, “37” → “01” → “37” → “99” → “37”, and repeats the same password three times every other time. The numerical values exemplified by “01”, “99”, etc. that are input in the middle are set to numbers different from the number “37” repeated every other time. At that time, “37” is obtained as a registered password and updated. That is, based on the input contents of the PIN number repeatedly input (the number “37” in the above example) and the update rule (in the above example, the same PIN number is input three times every other time). A new registration code number “37” is obtained.

  The third update rule conforms to the update rule when the input is repeated, for example, “03” → “03” → “03” → “07” → “07” → “07”. The number “3” in the first digit of the three input number “03” is the number of the tenth digit of the registered password, and the number “7” in the first digit of the subsequent three input number “07” is As the number of one's place in the registered password, “37” is used as the registered password. That is, the input contents of the PIN number repeatedly input (in the above example, “03” “07”) and the update rule (in the above example, the same number is input three times, followed by a different number three times) To obtain a new registered personal identification number “37”.

  However, the plurality of update rules are not limited to the three types as described above, but may be two types or four or more types.

[Third Embodiment]
Next, 3rd Embodiment of this invention is described based on drawing.
In the third embodiment, the configuration of the storage unit and the other configuration different in the processing configuration by the information processing unit are the same as those in the first embodiment. Therefore, only the different configuration will be described here, and the same configuration will not be described. Omitted.

  In the third embodiment, the storage unit is configured to store the registered personal identification information in association with operator identification information, and the information processing unit is connected to the information input unit in the personal identification information determination process. Based on the operator identification information and the password information that are input in this manner, it is determined whether or not the input password information matches the registered password information stored in the storage means and corresponding to the operator identification information. It is configured as follows.

  More specifically, there are a plurality of operators as persons who operate the information input operation unit J, and an identification number as an example of operator identification information for each of the plurality of operators, for example, “1 .., “2”, “3”... Are set, and the memory 34 serving as storage means stores different registered password information for each operator in a state managed in association with the identification number. For example, when there are a plurality of families in the home where the power supply facility is installed, the operation identification number and the registered password are stored for each person. Then, based on the identification number input by the information input operation unit J and the password information input by the information input operation unit J, the information processing means 100 obtains the password and registered password information for each operator. It is determined whether or not they match.

  That is, as shown in FIG. 5, the operation control unit 7 constituting the information processing means 100 sets setting instruction information for setting the operator's identification number in addition to the operator's password in step 3. Is output to the information display unit G. That is, a message “Register your identification number” is displayed in addition to the message “Register your PIN” on the information display section G.

  Then, in the input prompting process in step 9, the input of the identification number is prompted in addition to the password. That is, in addition to the message “Please enter your password”, the message “Please enter your identification number” is also displayed on the information display section G. Therefore, the operator inputs his / her identification number (any one of 1, 2, 3,...) And his / her personal identification number in the input process of step 10.

  Then, the operation control unit 7 is input based on the identification number input in the information input operation unit J and the code number input in the information input operation unit J in the determination process of step 11. It is determined whether or not the personal identification number is a registered personal identification number stored in the memory 34 in association with the identification number. In addition, the process of updating the registered password is performed separately for each operator.

[Another embodiment]
Hereinafter, other embodiments are listed.

(1) In the first embodiment, it is exemplified that the same personal identification number is inputted three times consecutively as the update rule, but another update rule is used instead of the update rule. It may be.
For example, as illustrated in the second embodiment, the same password number is repeatedly entered three times every other time, or it is configured to be an update rule, the same number is entered three times, and subsequently, It is good also as a structure which makes it a rule for an update to input a different number 3 times, and various structures other than such a structure are applicable.

(2) In the second embodiment, the information processing means has exemplified the one that changes the update rule every time the set time elapses. However, the present invention is not limited to such a configuration. The information processing means may change the update rule by instructing a switching command from a management device that is communicably connected via various communication means such as the above communication means. For example, a switching command may be instructed by communication from a management device managed by the installation company to an operation control unit in a power supply facility installed in each home.
