The lobby intercom 12 may be provided with an authentication terminal for authenticating a resident with a card key or the like, or may be provided near the authentication terminal. In that case, the electric lock of the lobby door or the dwelling door can be unlocked only by authentication.

  The alarm monitoring panel (administrator room unit) 13 includes a touch panel that constitutes a display operation unit, a handset that constitutes a call unit, an alarm lamp that constitutes an abnormality notifying unit, a speaker (not shown), and the like.

  The control device 14 is a device that controls signal transmission between the dwelling unit intercom 11 and the lobby intercom 12 or the alarm monitoring panel 13, and the dwelling unit intercom 11, the lobby intercom 12, and the alarm monitoring panel 13 are connected to this device. Yes.

  The authentication device 15 is a device that authenticates a resident based on, for example, information of a card key read by a resident authentication terminal (not shown) attached to the lobby intercom 12. The resident authentication is used for controlling the electric locks of the lobby door and the dwelling door.

  The charging system 2 is a system for charging an electric vehicle 3 that is generally called an EV. The charging system 2 is installed in a parking lot away from a residential building, a parking lot in a basement of a residential building, and the like. And a state monitoring means 23 for determining the empty state of the charging station 21. Each of the charging stations 21 is provided with a charging plug 22, a display operation panel (not shown) and the like in the parking space of the electric vehicle 3. The display operation unit may include a means for authenticating the dweller.

  The charging system 2 is connected to the control device 14 of the intercom system 1 by a serial cable based on, for example, EIA-232-D / E. However, there is no particular limitation on the connection form, and for example, a connection may be made with a parallel cable or a LAN cable.

  With reference to FIG. 3, the configuration of the intercom system 1 will be described with respect to functional blocks according to the present invention.

  The control device 14 includes a charging information receiving unit 14a that receives charging information from the charging system 2, and a charging information distributing unit 14b that specifies the address and distributes the charging information received by the charging information receiving unit 14a to the dwelling unit intercom 11. It has. As shown in the figure, a storage unit 14c that accumulates charging information in a time series as a log may be further provided.

  The dwelling unit intercom 11 includes a charging information display unit including a touch panel 11b, a speaker 11f, an audio output unit that outputs the charging information by voice, and a message lamp 11d that indicates the presence or absence of the charging information.

  Next, the basic operation of the intercom system 1 will be described. The dwelling unit intercom 11 and the control device 14 are connected by an intercom line 16 where signal transmission is performed by designating a destination and a source address. The protocol is not particularly limited, but for example, TCP / IP may be used. The signal transmission between the control device 14 and the lobby intercom 12 or the alarm monitoring panel 13 is the same. Note that a general twisted pair cable may be used for the signal line of the intercom line 16, but a dedicated cable may be used. Further, a cable in which a call signal, a call control signal, and a power source are separately wired or a multiplexed cable may be used.

  The basic functions and operations of the intercom system 1 are the same as those in the prior art. That is, when a calling operation specifying a dwelling unit number is performed on the lobby intercom 12, the control unit 14 calls the dwelling unit interphone 11 of the specified dwelling unit. When the call key 11e is operated with the called dwelling unit intercom 11, the control device 14 configures an exclusive audio channel between the lobby intercom 12 and the dwelling unit intercom 11, so that the visitor and the dweller can communicate with each other. Allow calls. Thereafter, when the call key 11e is operated again or when a predetermined time has elapsed, the audio channel is released. Note that there may be a plurality of lobby interphones 12, and even in this case, the audio channel is exclusively controlled.

  Furthermore, if the intercom system 1 is a television system, the video camera provided on the lobby intercom 12 side and the dwelling unit intercom 11 to be called from the time when the call operation is performed on the lobby intercom 12 until the call channel is released. An exclusive video channel is configured between the two. If it does in this way, it can respond, monitoring the visitor's picture with dwelling intercom 11.

  Also, the function and operation as an alarm monitoring system are the same as in the prior art. That is, when the security sensor detects an abnormality, the dwelling unit intercom 11 displays an alarm screen on the touch panel 11b and outputs an alarm message from the speaker 11f. Further, the dwelling unit intercom 11 notifies the alarm monitoring panel 13 of the occurrence of the abnormality. Upon receiving the notification, the alarm monitoring panel 13 outputs an alarm, and outputs an evacuation message or the like from the dwelling unit interphone 11 that has notified the occurrence of an abnormality or the neighboring dwelling unit intercom 11 according to the operation of the manager. In addition, the occurrence of abnormalities can be transferred to disaster prevention centers.

  Next, a cooperative operation between the intercom system 1 and the charging system 2 which is a feature of the present invention will be described. In short, the intercom 11 receives the predetermined operation for confirming the charging, and then the charging unit 2 requests the charging information from the charging system 2 via the charging information distribution unit 14b and the charging information receiving unit 14a. When the charging information is returned from, charging information of the dweller's electric vehicle 3 is notified. By notifying such charging information, the dweller can easily check the state of charge of the electric vehicle 3 by the charging system 2 at a remote location while in the dwelling unit.

  Here, the charging information request signal transmitted from the charging information receiving unit 14a to the charging system 2 includes dwelling unit information for identifying the requesting dwelling unit. The dwelling unit information may be a dwelling unit number. If the charging system 2 is configured to require resident identification information, the resident unit number may be replaced with the resident identification information by referring to the authentication device 15 or the like. Alternatively, the dwelling unit intercom 11 may transmit a request signal to which the resident identification information is added.

  Also, protocol conversion is necessary for communication with the charging system 2. That is, the procedure for converting the request signal received from the dwelling unit intercom 11 into a format accepted by the charging system 2 may be performed by either the charging information distribution unit 14b or the charging information reception unit 14a.

  The charging system 2 may be configured to periodically collect event information from each of the charging stations 21 or may be configured to collect event information from each of the charging stations 21 every time a charging information request signal is received from the charging information receiving unit 14a. Good. In any configuration, when the charging information request signal is received from the charging information receiving unit 14a, the electric vehicle 3 of the dwelling unit is determined based on the dwelling unit information included in the request signal from the collected event information. Search related items and send back as charging information. The event referred to here indicates a state change such as charging start, charging completion, charging error, and attachment / detachment of the charging plug 22.

  Therefore, the charging information returned by the charging system 2 includes an event type for specifying an event, but also includes dwelling unit information and date / time information when the event occurs (or event information is collected). The necessary dwelling unit information can be easily obtained by using the authentication device 15 provided in the interphone system 1 without separately preparing an authentication device on the charging system 2 side.

  The format and protocol of the charging information are not particularly limited. For example, a predetermined number of bits may be assigned to each of event information, dwelling unit information, and date / time information, and the information may be coded as character string information.

  When the charging information receiving unit 14a provided in the control device 14 receives the charging information returned from the charging system 2, the charging information receiving unit 14a transfers the charging information to the charging information distributing unit 14b. The charging information distribution unit 14b decodes the charging information, confirms the dwelling unit information included therein, converts the protocol, adds the address of the dwelling unit intercom 11 of the request signal transmission source, and outputs it to the interphone line 16 To do. If the charging information is saved as a log at this time, it can be used to isolate the cause when the system does not operate normally. Further, even when the stored contents of the dwelling unit intercom 11 are lost due to a power failure or the like, it is also possible to recover the storage part related to the charging state of the dwelling unit intercom 11 from the log and continue to notify the charging state.

  After receiving the charging information request signal, the dwelling unit intercom 11 receives the charging information designated by its own address, decodes the content, and performs notification corresponding to the event type included in the charging information. .

  In the flowchart of FIG. 4, general signal transmission between the charging system 2 and the intercom system 1 is described in time series.

  According to this flowchart, at time T1, the dwelling unit intercom 11 receives an operation of the menu key 11c and transmits a request signal for charging information to the charging information distribution unit 14b. The request signal is transmitted to the charging system 2 via the charging information distribution unit 14b and the charging information reception unit 14a.

  At time T2, the charging system 2 searches the charging station 21 based on the received request signal, and returns charging information related to the electric vehicle 3 of the dwelling unit. The returned charging information is transmitted to the dwelling intercom 11 that transmitted the request signal via the charging information receiving unit 14a and the charging information distributing unit 14b. The charging information distribution unit 14b in the middle of the route records charging information as a log.

  At time T3, the dwelling unit intercom 11 notifies the received charging information.

  Hereinafter, according to FIG. 5A to FIG. 5D, a charging information notification example will be specifically described.

  FIG. 5A is an example of a notification screen when the electric vehicle 3 is not connected. This notification screen is displayed in response to the inquiry when the electric vehicle 3 is not connected, and the date and time of confirmation and a message “EV not connected” are arranged.

  Moreover, FIG.5 (b) is an example of the alerting | reporting screen corresponding to charging. On the notification screen, a date and time information included in the charging information, a message “EV charging”, and a progress bar indicating the amount of charge at the date and time displayed on the screen are arranged. Such a progress bar can be easily realized if the charging system 2 returns charging information including the amount of charge of the electric vehicle 3. Of course, this charging information includes information indicating charging as an event type. Here, the charge amount may be a predetermined value such as 20%, 40%, 60%, or 80%.

  However, a configuration in which charging information is not processed when the charging system 2 is being charged is also conceivable. In such a case, charging is performed every time the operation of the menu key 11c is accepted after the dwelling interphone 11 receives the charging information for notifying the start of charging once until receiving the charging information for notifying the completion of charging. The notification screen may be generated. In the notification screen, the date and time of the date and time information included in the charging information notifying the start of charging may be used as a starting point, and the elapsed time from there may be shown as a progress bar. At that time, the date and time when the menu key 11c is operated, that is, the current date and time may be displayed as the date and time. In this way, if the configuration is such that the progress is informed by the progress bar during charging, it is possible to stop the charging and use the electric vehicle 3 without worrying when a certain amount of charging is possible.

  FIG. 5C is an example of a notification screen corresponding to the completion of charging. On the notification screen, a date and time information included in the charging information, a message “EV charging completed”, and a progress bar indicating the amount of charge at the date and time displayed on the screen are arranged. As can be seen from FIGS. 4A to 4C, the progress bar extends toward the right side as charging progresses.

  FIG. 5D is an example of a notification screen corresponding to a charging abnormality. On the notification screen, the date and time of the date and time information included in the charging information and a message “EV charging abnormality” are arranged. The charging abnormality is notified when a voltage abnormality occurs during charging. Note that the display colors of the “EV charge start”, “EV charge in progress”, “EV charge complete”, and “EV charge abnormality” messages may be different so that they can be approximated at a glance. For example, if "EV charging start", "EV charging" is displayed in red, "EV charging completed" is displayed in green, "EV charging abnormal" is displayed in red blinking, etc. The contents of the notification can be understood. Also, the message lamp 11d may have different lighting colors corresponding to the display colors of these messages. Thus, if it is set as the structure which alert | reports a charging abnormality, it will become possible to deal with a failure quickly, such as stopping charging and calling a repairer when a charging abnormality is notified.

  More preferably, the charging system 2 includes a state monitoring unit 23 that monitors the charging station 21, determines the empty state, and outputs empty determination information. In this case, when the charging information distribution unit 14b receives a request for availability information from the dwelling unit interphone 21, the charging information distribution unit 14b receives the availability determination information from the charging system 2, specifies the address of the dwelling unit interphone 11 that has made the inquiry, Distributes vacancy discrimination information. And the dwelling unit intercom 11 is good to set it as the structure which receives the empty determination information and alert | reports the empty state of the charging station 21. FIG.

  The state monitoring unit 23 may detect, for example, an empty state of the charging plug 22 of the charging station 21.

  FIG. 6A and FIG. 6B are examples of notification screens that display the empty information of the charging station 21. FIG. 6A is a screen in the case where there are two vacancies in the charging station 21, and the date and time of the date / time information included in the charging station information and the message “There are two vacant charging stations” are arranged. .

  On the other hand, FIG. 6B shows a screen in the case where there is no space in the charging station 21, where the date and time of the date / time information included in the charging station information and a message “the charging station has no space” are arranged. In this way, the vacant state of the charging station 21 can be determined by a simple operation of the dwelling intercom 11, so that after confirming the vacant state, the user can go to the parking lot to charge his own electric vehicle 3. Convenience is greatly improved.

  Moreover, when the dwelling unit intercom 11 receives a predetermined operation, the dwelling unit intercom 11 transmits a request for automatic vacancy notification of the charging station to the charging information distribution unit 14b, and then automatically notifies the vacancy occurrence information when a vacancy occurs in the charging station. You may do it. In this case, the charging information distribution unit 14 b stores and holds the empty automatic notification request until the empty occurrence information is returned to the dwelling unit intercom 11. It should be noted that an automatic empty notification request may be transmitted by placing an “automatic empty notification” button or the like on the screen when there is no empty, and touching it. As described above, if a mechanism for automatically notifying that the charging station 21 is vacant is used, the convenience is further improved. It should be noted that the automatic availability notification request can be added to a time designation option so that it is automatically notified when a vacancy occurs after a desired time. It is very convenient when you want to.
