  FIG. 3 is an explanatory diagram of an operation of requesting power supply by the communication terminal 32 at the installation location of the outlet 11 and the DC outlet 12 in the first embodiment. At the place where the outlet 11 or the DC outlet 12 is installed, a remote operation preventing device 53 is provided in the vicinity of the outlet 11 or the DC outlet 12. The remote operation preventing device 53 is provided with a display device 54 for displaying a variable identification mark for identifying the outlet 11 or the DC outlet 12, and the display device 54 identifies the outlet 11 or the DC outlet 12. A variable identification mark 56 is displayed. FIG. 3 shows a case where the variable identification mark 56 is a QR code. As described above, the variable identification mark 56 is updated by the identification mark update unit 55 of the center server 31 and updated and displayed by the control unit 21 every time the outlet 11 or the DC outlet 12 is used.

  When the user wants to use the outlet 11 or the DC outlet 12 at the installation location, the user reads the variable identification mark 56 by the communication terminal 32 and transmits it to the center server 31. The center server 31 inputs a variable identification mark 56 to the outlet identifying unit 36. The outlet identifying unit 36 identifies the outlet 11 and the DC outlet 12 to be supplied with current based on the variable identification mark 56 and determines whether or not it is the latest identification mark transmitted by the identification mark updating unit 55. If it is an identification mark, it is determined that there is information on energization.

  Further, the current supply command output unit 37 of the center server 31 confirms whether or not there is authentication by the user in the power supply request from the communication terminal 32, and when the confirmation is made, the outlet identified by the outlet identifying unit 36 is confirmed. 11 and a current supply command to the current control unit 14 corresponding to the DC outlet 12. As a result, power is supplied to the outlet 11 and the DC outlet 12.

  FIG. 4 is a flowchart showing the operation of Example 1 of the public power supply system according to the embodiment of the present invention. First, the user goes to the installation location of the outlet 11 or the DC outlet 12 that he / she wants to use, and reads the variable identification mark 56 displayed on the display device of the remote control preventing device 53 at the installation location by the communication terminal 32 (S1). . The center server 31 determines whether there is information that can be energized based on the variable identification mark 56 transmitted from the communication terminal 32 (S2). This is determined based on whether or not the variable identification mark 56 is the latest identification mark. When the variable identification mark 56 is the latest identification mark, it is determined that there is information indicating that energization is possible (S2). Then, the center server 31 updates the identification mark (S3) and transmits a new identification mark to the control unit 21 of the current control unit 14. As a result, the control unit 21 of the current control unit 14 displays the updated identification mark on the display device 54 of the remote operation preventing device 53.

  When the user inputs the login password (S4), the center server 31 identifies the installation location of the outlet 11 and the DC outlet 12 to be supplied with current based on the variable identification mark 56 (S5). It is confirmed whether there is authentication based on the login password (S6). If authentication cannot be confirmed, the process ends.

  On the other hand, when the authentication is confirmed, the center server 31 displays a use confirmation screen on the communication terminal 32 (S7), and confirms whether or not the user intends to use the outlet 11 or the DC outlet 12. Perform (S8). If there is no usage confirmation from the user, the process ends. If there is a usage confirmation, the center server 31 displays a usage agreement screen on the communication terminal 32 (S9), and the user agrees to the agreement. Whether or not (S10).

  When the user agrees to the rules, the center server 31 outputs a current supply command to the current control unit 14 (S11). This is because it is already determined in step S2 that there is information indicating that power can be supplied. When receiving the current supply command, the current control unit 14 starts energization (S12), starts the timer 26, and starts counting the timer 26 (S13). Thereby, the usage time of the outlet 11 or the DC outlet 12 is measured.

  Next, the current control unit 14 determines whether or not the leakage has occurred by the leakage detectors 16a and 16b (S14). If the leakage has occurred, the leakage detectors 16a and 16b open the switches 18a and 18b to open the outlet 11 or The current supply to the DC outlet 12 is cut off, and the leakage detection information is stored in the leakage detection history storage unit 22 (S15), and the user information (power consumption, usage time, usage fee) up to that point is tabulated. (S16), and the process ends.

  If there is no leakage, the control unit 21 determines whether the supply current to the outlet 11 or the DC outlet 12 exceeds the overcurrent set value (S17). The unit 21 opens the switches 18a and 18b to cut off the current supply to the outlet 11 and the DC outlet 12, and stores the overcurrent detection information in the overcurrent detection history storage unit 24 (S18). User information (power consumption, usage time, usage fee) is tabulated and stored (S16), and the process is terminated.

  If the current is not exceeded, the use of the power supply is continued (S19), and the control unit 21 determines whether or not the use is finished (S20). If the use is finished, the user information up to that point (power consumption, use The time and usage charges are tabulated and stored (S16), and the process is terminated. When the use of the outlet 11 or the DC outlet 12 is not finished, it is determined whether or not the usage time measured by the timer 26 is equal to or greater than the limit value stored in the usage time limit value storage unit 25 (S21). If it is not a limit, the process returns to step S14. If it is a time limit, the user information (power consumption, usage time, usage fee) up to that point is totalized and stored (S16), and the process is terminated. Whether or not the use is finished is determined, for example, by whether or not a termination command is output from the communication terminal 32 or whether or not the supply currents Ia and Ib to the outlet 11 and the DC outlet 12 have become zero over a predetermined time. To do.

  Here, the leakage detection history information such as the leakage occurrence date and time stored in the leakage detection history storage unit 22 and the overcurrent detection such as the overcurrent detection date and overcurrent value stored in the overcurrent detection history storage unit 24 are detected. The history information is transmitted to the center server 31 in response to a request from the center server 31 and is managed by the center server 31.

  In the above description, the usage time limit value storage unit 25 for setting the usage time limit value of the outlet 11 and the DC outlet 12 and the usage time of the outlet 11 and the DC outlet 12 are set in the usage time limit value storage unit 25. Although the timer 26 for turning off the current supplied to the outlet 11 or the DC outlet 12 is provided in the current control unit 14 when the limit value is reached, it may be provided in the center server 31. In this case, when the count value of the timer 26 reaches the limit value set in the use time limit value storage unit 25, the center server 31 notifies the control unit 21 of the current control unit 14 to that effect. Become.

  The use time limit value set in the use time limit value storage unit 25 may be set in advance as a fixed value, or the center server 31 may restrict the use time to the user from the center server 31 to the communication terminal 32. The limit value designated by the user from the communication terminal 32 may be set by inquiring about the value.

  As described above, according to the first embodiment, when the outlet 11 or the DC outlet 12 is installed in a predetermined public place in advance and the user requests the power supply from the communication terminal 32 to the outlet 11 or the DC outlet 12, The center server 31 outputs a current supply command to the current control unit 14 when receiving information indicating that energization is possible using the remote operation preventing device 53 installed near the outlet 11 or the DC outlet 12. Therefore, the current supply command is output after the operation at the place where the outlet 11 and the DC outlet 12 are installed, and the outlet 11 and the DC outlet 12 are operated remotely from the outlet 11 and the DC outlet 12. Can be prevented from being energized. As a result, the user can use power without operating in a public place that is not in the consumer, and convenience is improved.

  The center server 31 transmits information on the installation location of the outlet 11 or the DC outlet 12 to the communication terminal 32 when a user requests a search for the installation location of the outlet 11 or the DC outlet 12 from the communication terminal 32. Therefore, the user can easily grasp the installation location of the outlet 11 and the DC outlet 12, and convenience is improved. The center server 31 provides detailed information on the use of the outlets 11 and the DC outlets 12 for each installation location in addition to the information on the installation locations of the outlets 11 and the DC outlets 12. The convenience of use of the outlet 12 is further improved.

  When the usage time of the outlet reaches the limit value, the current control unit 14 turns off the current supplied to the outlet 11 and the DC outlet 12, so that the outlet user mistakenly connected the electric device for a long time. Even if it is left as it is, it can be automatically turned off and safety is improved.

  Since the center server 31 aggregates user information (power consumption, usage time, usage fee) for each user, the power consumption, usage time, usage fee can be easily calculated, and accounting can be easily performed. Yes. When there is a user information (usage power consumption, usage time, usage fee) inquiry request from the communication terminal 32 by the user, the center server 31 uses the communication terminal to collect the information on the usage power charge calculated for each user. Therefore, the user can easily grasp user information (power consumption, usage time, usage fee).

  Further, the current control unit 14 monitors the supply current to the outlet 11 and the DC outlet 12, and supplies current to the outlet 11 and the DC outlet 12 so as not to exceed a predetermined overcurrent set value. Electric power can be supplied to the outlet 11 and the DC outlet 12, and it is possible to prevent adverse effects on the distribution line and the host system to which the outlet 11 and the DC outlet 12 are connected. Moreover, since the setting of the overcurrent setting value of the current control unit 14 can be changed from the center server 31, it is possible to easily cope with a change in the capacity of the outlet 11 or the DC outlet 12.

For the operation of the second embodiment shown in FIG. 7, instead of step S2 for operating the operation button, step S2a for displaying a new identification mark and step S2b for inputting a new identification mark are provided.

  In FIG. 10, the user first goes to the installation location of the outlet 11 or the DC outlet 12 that he / she wants to use, and reads the fixed identification mark 59 formed on the remote operation preventing device 53 at the installation location by the communication terminal 32 (S1). ). The fixed identification mark 59 read by the communication terminal 32 is transmitted from the center server 31. When the fixed identification mark 59 is received, the center server 31 sends the fixed identification mark 59 to the communication terminal 32 that has transmitted the fixed identification mark 59. A new identification mark 62 is transmitted. Thereby, the new identification mark 62 is displayed on the communication terminal 32 (S2a). The user causes the reading device 60 of the remote operation preventing device 53 to read the new identification mark 62 received from the center server 31, and inputs the new identification mark to the current control unit 14 (S2b). As a result, information indicating that energization is possible is input to the current control unit 14.

  Next, the user inputs the login password (S3), and the center server 31 identifies the installation location of the outlet 11 and the DC outlet 12 to be supplied with current based on the fixed identification mark 59 (S4), and login. It is confirmed whether there is authentication based on the password (S5). If authentication cannot be confirmed, the process ends. On the other hand, when the authentication is confirmed, the center server 31 displays a use confirmation screen on the communication terminal 32 (S6), and confirms whether or not the user intends to use the outlet 11 or the DC outlet 12. If the use confirmation is not received from the user, the process is terminated. If the use is confirmed, the center server 31 displays a use agreement screen on the communication terminal 32 (S8). It is confirmed whether or not the agreement is agreed (S9). When the user agrees to the terms, the center server 31 outputs a current supply command to the current control unit 14 (S10).

  Then, the current control unit 14 determines whether there is information indicating that energization is possible (S11). This is determined by whether or not a new identification mark 62 is input from the reading device 60 of the remote operation preventing device 53 to the current control unit 14. When a new identification mark 62 is input from the reading device 60 of the remote operation preventing device 53, the control unit 21 of the current control unit 14 validates the current supply command (S12) and starts energization (S13). The current control unit 14 starts energization and activates the timer 26 to start counting of the timer 26 (S14). Thereby, the usage time of the outlet 11 or the DC outlet 12 is measured.

  Next, the current control unit 14 determines whether or not the leakage is generated by the leakage detectors 16a and 16b (S15). If the leakage is generated, the leakage detectors 16a and 16b open the switches 18a and 18b to open the outlet 11 or The current supply to the DC outlet 12 is cut off, and the leakage detection information is stored in the leakage detection history storage unit 22 (S16), and the user information (power consumption, usage time, usage fee) up to that point is tabulated. (S17), and the process ends.

  If there is no leakage, the control unit 21 determines whether the supply current to the outlet 11 and the DC outlet 12 exceeds the overcurrent set value (S18). The unit 21 opens the switches 18a and 18b to cut off the current supply to the outlet 11 and the DC outlet 12, and stores the overcurrent detection information in the overcurrent detection history storage unit 24 (S19). User information (power consumption, usage time, usage fee) is tabulated and stored (S17), and the process ends.

  If the current is not exceeded, the use of the power supply is continued (S20), and the control unit 21 determines whether or not the use is finished (S21). If the use is finished, the user information up to that point (power consumption, use The time and usage charges are tabulated and stored (S17), and the process is terminated. When the use of the outlet 11 or the DC outlet 12 has not ended, it is determined whether or not the usage time measured by the timer 26 has exceeded the limit value stored in the usage time limit value storage unit 25 (S22). If it is not a limit, the process returns to step S15. If it is a time limit, the user information (power consumption, usage time, usage fee) up to that point is totalized and stored (S17), and the process is terminated. Whether or not the use is finished is determined, for example, by whether or not a termination command is output from the communication terminal 32 or whether or not the supply currents Ia and Ib to the outlet 11 and the DC outlet 12 have become zero over a predetermined time. To do. In the case of Example 3, the same effect as that of Example 2 can be obtained.

  Next, Example 4 of the public power supply system according to the embodiment of the present invention will be described. FIG. 11 is a configuration diagram of Example 4 of the public power supply system according to the embodiment of the present invention. The fourth embodiment is different from the first embodiment shown in FIG. 1 in that a user specifying information reader for reading user specifying information for specifying a user is provided in the vicinity of the outlet 11. When the specific information reader reads the user specific information, the user specific information is input from the current control unit, and when the user specific information is registered as a user, a current supply command is issued to the current control unit. It is designed to output.

  FIG. 11 shows a case where a non-contact IC reader 65 that reads the contents of the non-contact IC 64 is provided near the outlet 11 as the user identification information reader. The non-contact IC reader 65 is connected to the communication port 27 of the current control unit 14, and the center server 31 stores the ID of the non-contact IC 64 registered as a user in the storage device as user registration information 66.

  In the user registration information 43, users who have agreed to the terms of use of the outlet 11 are registered. Therefore, for a user who intends to agree to the terms of use of the outlet 11 from now on, the center server 31 also includes a user registration unit 67 for creating user registration information 66 when the user performs user registration. Have. The same elements as those in FIG. 1 are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 11, the non-contact IC reader 65 is connected to the current control unit 14 and is installed in the vicinity of the outlet 11 and the DC outlet 12. The non-contact IC reader 65 reads the content of the non-contact IC 64 when the non-contact IC 64 carried by the user is held over and outputs it to the communication port 27 of the current control unit 14.

  The non-contact IC 64 is an IC incorporated in a mobile phone Osaifu-Keitai (registered trademark), a Feilca card, etc., and is an IC having information that can identify a user.

  When the communication port 27 of the current control unit 14 inputs the content of the non-contact IC 64 read from the non-contact IC reader 65, the content of the non-contact IC is transmitted to the center server 31 via the Internet 29. The outlet identifying unit 36 of the center server 31 identifies the communication port 27 to which the content of the non-contact IC 64 has been transmitted, and identifies the non-contact IC reader 65. Then, the current supply command output unit 37 of the center server 31 determines whether or not the input ID of the non-contact IC is registered in the user registration information 66, and the ID of the non-contact IC 64 is the user registration information 66. Is registered, the current supply command is output to the current control unit 14 via the Internet 29 or the telephone network 30. Thus, the control unit 21 of the current control unit 14 controls supply of current to the outlet 11 and the DC outlet 12 based on the current supply command.

  FIG. 12 is an explanatory diagram of an operation for requesting power supply by the non-contact IC 64 at the place where the outlet 11 or the DC outlet 12 is installed. A non-contact IC reader 65 is provided near the outlet 11 or the DC outlet 12 at the place where the outlet 11 or the DC outlet 12 is installed.

  When the user wants to use the outlet 11 or the DC outlet 12 at the installation location, the user holds the non-contact IC 64 over the non-contact IC reader 65. The non-contact IC reader 65 reads the content of the non-contact IC 64 held by the user and outputs it to the communication port 27 of the current control unit 14. The communication port 27 of the current control unit 14 transmits the content of the input non-contact IC 64 to the center server 31 via the Internet 29. The outlet identifying unit 36 of the center server 31 identifies the non-contact IC reader 65 by identifying the communication port 27 to which the content of the non-contact IC 64 has been transmitted, and the current supply command output unit 37 of the center server 31 is It is determined whether or not the input ID of the non-contact IC 64 is registered in the user registration information 66. If the ID is registered in the user registration information 66, the current control unit 14 is connected via the Internet 29 or the telephone network 30. Outputs a current supply command.

  FIG. 13: is a flowchart which shows operation | movement of Example 4 of the public power supply system which concerns on embodiment of this invention. First, the user goes to the installation location of the outlet 11 or the DC outlet 12 to be used, and holds the non-contact IC 64 over the non-contact IC reader 65 at the installation location (S1). The outlet identifying unit 36 of the center server 31 identifies the installation location of the outlet 11 and the DC outlet 12 to be supplied with current by identifying the non-contact IC reader 65 that has read the contents of the non-contact IC 64 (S2).

  The current supply command output unit 37 of the center server 31 determines whether or not the ID of the non-contact IC 64 read by the non-contact IC reader 65 is registered in the user registration information 66 (S3). If it is not registered in 66, the process is terminated.

  When the ID of the non-contact IC 64 read by the non-contact IC reader 65 is not registered in the user registration information 66, the user registration unit 67 may prompt user registration. For example, a registration screen of user registration information 66 is displayed on the display unit of the non-contact IC reader 65 to prompt user registration.

  On the other hand, if it is determined in step S3 that the user is registered, the current supply command output unit 37 of the center server 31 outputs a current supply command to the current control unit 14 (S4). This is because the registered user is a user who has already agreed to the terms of service of the outlet 11. When receiving the current supply command, the current control unit 14 starts energization (S5), starts the timer 26, and starts counting the timer 26 (S6). Thereby, the usage time of the outlet 11 or the DC outlet 12 is measured.

  The current control unit 14 determines whether or not leakage has occurred by the leakage detectors 16a and 16b (S7). If leakage occurs, the leakage detectors 16a and 16b open the switches 18a and 18b to open the outlet 11 or the DC outlet 12 The leakage current detection information is stored in the leakage detection history storage unit 22 (S8), and the previous user information (power consumption, usage time, usage fee) is tabulated and stored. (S9), the process ends. If there is no leakage, the control unit 21 determines whether the supply current to the outlet 11 or the DC outlet 12 exceeds the overcurrent set value (S10). The unit 21 opens the switches 18a and 18b to cut off the current supply to the outlet 11 and the DC outlet 12, and stores the overcurrent detection information in the overcurrent detection history storage unit 24 (S11). User information (power consumption, usage time, usage fee) is tabulated and stored (S12), and the process is terminated. If the current is not exceeded, use of the power supply is continued (S12).

  Then, the control unit 21 determines whether or not the use is finished (S13), and when the use is finished, the process is finished. When the use of the outlet 11 or the DC outlet 12 has not ended, it is determined whether or not the usage time measured by the timer 26 has exceeded the limit value stored in the usage time limit value storage unit 25 (S14). If it is not a limit, the process returns to step S7, and if it is a time limit, the process is terminated. Whether or not the use has ended is determined, for example, by whether or not the non-contact IC 64 is held over the non-contact IC reader 65 to output an end command, or the supply currents Ia and Ib to the outlet 11 and the DC outlet 12 are determined for a predetermined time. Judgment is made based on whether or not it has become zero.

  According to Example 4 of the embodiment of the present invention, a user can use electric power not only in a communication terminal but also in a non-contact IC or in a public place that is not in a consumer. In this case, since the registered user is a user who has already agreed to the terms of use of the outlet 11, processing for confirming the agreement of the terms of use becomes unnecessary.

  In the above description, the non-contact IC reader 65 for reading the contents of the non-contact IC 64 is provided near the outlet 11 as a user identification information reader near the outlet 11 in the first embodiment shown in FIG. As shown in FIG. 14, a non-contact IC reader 65 that reads the contents of the non-contact IC 64 can be provided in the vicinity of the outlet 11 as a user identification information reader in the second embodiment shown in FIG. is there.
