  Hereinafter, as an example of a mode for carrying out the present invention, an embodiment relating to a power control system suitable for implementation in an apartment house such as an apartment will be described with reference to the accompanying drawings.

  FIG. 1 shows a configuration of a power control system employing the present invention. The power control system of the present invention is a so-called micro (smart) grid (or smart house) power network installed in an apartment house such as a condominium, a commercial AC power source (not shown), power generation means (solar cell panel 801), It consists of power supply / reception elements such as a storage battery 701 and chargers (303, 304) of electric vehicles (5001, 5002).

  Furthermore, the collective housing in which the power control system of the present invention is installed is provided with a so-called delivery box (delivery locker) used for delivery of deliverables, and an article collection device 100 configured as a mailbox and the like. The functions of the central control device 200 constituting the electric control unit are integrated into the control unit 2001 that controls the receipt of the articles of the article collection apparatus 100. That is, the control unit 2001 of the article receiving device 100 also serves as the central control device 200 constituting the power supply / reception control unit of the power control system. Below, this control part comprised by the control part 2001 of the goods receipt apparatus 100 is referred to as the central control apparatus 200.

  The central control device 200 is a predetermined communication for communicating with a CPU as a main control unit, a ROM storing a program to be described later, a RAM used as a work area, other blocks of the system, and an external management server (not shown). It consists of a system interface (for example, IEEE 802.3 network interface, serial interface, etc.), a time measuring means such as a real time clock (RTC) for measuring the current time, and an HDD (hard disk drive) for storing database information described later. The Central controller 200 operates with a commercial AC power supply during normal times, but operates as long as the power supply from solar panel 801 or storage battery 701 continues to be supplied even when the commercial AC power supply fails, for example. Configure it to be possible.

  By adopting such a configuration, it is possible to integrate and combine multiple control units that perform intelligent control necessary for multi-dwelling units, so that power supply and reception control of electric power control systems, charging of electric vehicles, and receipt of goods can be achieved at a small installation cost. It is possible to provide high value-added services by linking device control.

  The power control system of FIG. 1 includes the following power supply / reception elements.

  In FIG. 1, reference numeral 801 denotes a solar cell panel, which is installed on the roof of an apartment house or the like, and generates DC power by solar energy. The converter 802 is, for example, a DC-DC converter, and converts the output voltage of the solar battery panel into a voltage that can be supplied to another DC load (for example, the storage battery 701 described below) through the main line of the system. Converter 802 may be a DC-AC converter or the like as necessary. In addition, when selling power to an electric power company, a purchased wattmeter from the commercial AC power supply (not shown) side, a reverse power wattmeter to measure surplus power from solar power generation, etc. (Not shown) is further installed. A configuration in which a wind power generator or the like is provided instead of (or in addition to) the solar cell panel 801 may be used.

  Reference numeral 701 denotes a storage battery, which is a storage battery of a predetermined format such as a lead battery, and can be charged by the output of the solar battery panel 801 (or the power of a commercial AC power supply as required). Since the solar cell panel 801 is a power generation unit capable of generating power only during the sunshine hours, a power storage unit such as the storage battery 701 is required when used for lighting a lighting fixture described later at night.

  Reference numeral 500 denotes a power load of a common part of the apartment house (hereinafter, common part load). Here, an entrance illumination 501 (for convenience, entrance illumination is used here, but this illumination means or illumination of a hall, a common passage, a staircase, etc.) The automatic door 502 and the elevator 503 are illustrated, but other common part loads such as a water pump may be included. Driving control of the entrance lighting 501, the automatic door 502, and the elevator 503 is controlled via the control units 601 to 603, respectively.

  The control units 601 to 603 can control power supply to the entrance lighting 501, the automatic door 502, and the elevator 503, respectively, and can detect a power meter (or ammeter) and a power supply state (supply power or current value) to each load. The control device 200 can grasp the driving state of each shared unit load via these control units 601 to 603.

  Further, in this system, a sunshine sensor or a human sensor is arranged at a predetermined position in the apartment house (not shown), and the central controller 200 determines whether, for example, the entrance lighting 501 is not lit unnecessarily. can do.

  The shared portion load 500 is basically driven by the output of the solar cell panel 801 or the output of the storage battery 701 (or the battery of the electric vehicle 5001, 5002,..., If necessary), and the solar cell panel 801 or storage battery 701. The central controller 200 performs control so that the commercial AC power supply is used when the output of the power supply is insufficient.

  The exclusive unit 508 corresponds to the power load in each occupant's room, but in the system, power can be supplied from the solar cell panel 801 or the storage battery 701 (or the battery of the electric vehicle 5001, 5002,..., If necessary). So that Since each unit exclusive unit 508 is usually provided with a wattmeter (power meter), the control may be more complicated than the common unit load, but the central control device 200 (the control unit 2001 of the article receiving device). Can control power supply / reception based on a resident ID (for example, recorded in an ID card 111 described later).

  For example, when power is supplied from the solar cell panel 801 or the storage battery 701 (or the battery of the electric vehicle 5001, 5002,. Charges can also be made with low-cost electricity charges (however, whether such a service can be provided and how it depends on the management rules of the apartment house).

  For example, a solar cell is controlled by controlling power supply / reception between power supply / reception elements of a power grid using data recorded in association with a resident ID in a database managed by the central control device 200 (control unit 2001 of the article collection device). Electric power can be supplied from the panel 801 or the storage battery 701 (or the batteries of the electric vehicles 5001, 5002,...) As necessary to each private unit 508, for example, different from the power company (for example, cheaper than the power company) Can be charged.

  In addition to those described with respect to the entrance lighting 501, the automatic door 502, and the control units 601 to 603 of the elevator 503, the main part of the main line of the power grid of the apartment house where the present system is installed has a power meter (or ammeter), Detection means such as a human sensor is arranged so that actual power distribution and power demand can be detected. The central control device 200 can detect a change in power distribution and power demand every moment through these detection means, and can switch the power supply / reception route as necessary. For example, in FIG. 1, a solar cell panel 801 is illustrated as a power generation element. However, the output of the solar cell panel 801 and the common unit load 500 (or the dedicated door unit 508, the charger 303, 304 of the electric vehicle, etc.) The state of the power supply output is measured, and if there is surplus power in the output of the solar battery panel 801, the power supply / reception path is switched so that the storage battery 701 can be charged by the solar battery panel 801 (FIG. 3 described later). In addition, line switching means such as a relay or an analog switch is arranged at a necessary position in the power network for such switching of the power supply / reception path.

  In this embodiment, the chargers 303, 304 of the electric vehicles 5001, 5002,... Are also incorporated in the system as power supply / reception elements that the central control device 200 performs power supply / reception control. Charging of the electric vehicles 5001 and 5002 by the chargers 303 and 304 is performed not only by the commercial AC power supply but also by the output of the solar cell panel 801 or the storage battery 701. Further, in this embodiment, when the output of the solar cell panel 801 or the storage battery 701 is insufficient, the battery of the electric vehicles 5001 and 5002 is used to supply power to the common unit load 500 and the dedicated units 508. Can also be done.

  For this purpose, in this embodiment, a bidirectional DC-AC (AC-DC) converter 803 is disposed as a power supply / reception element. The converter 803 converts the DC output of the solar cell panel 801 to the storage battery 701 (or on the main line) into a single-phase (or three-phase) 100 V (or 200 V) AC output required by the chargers 303 and 304.

  Further, some recent electric vehicles are configured to be able to supply the output of the battery to other loads. When the electric vehicles 5001 and 5002 are such vehicle types, the converter 803 includes the electric vehicle 5001, It is also used to convert a direct current (for example, 12V) output from an outlet of 5002 into an alternating current and supply power to another load.

  Here, the configuration of the chargers 303 and 304 of the electric vehicle will be described. The charger 303 is configured as a so-called parent device, and includes a display 3031 including an LCD panel, a card reader 3032, and a keyboard 3033.

In addition, an operation related to the charging service of the resident (or manager) can be performed on the console 103 of the article receiving apparatus 100 described later.

  In order not to use the ID card 111 other than the apartment house where the present system is installed, the ID card 111 stores specific key information indicating that the card is a regular card that can be used in the apartment house. Alternatively, ID information such as a room number can be encrypted and recorded using key information that can be used only in the apartment house.

  Further, since the ID card 111 records the resident ID, it functions as a key for opening and closing the entrance door (not shown, so-called auto-lock controlled entrance door) of the housing complex and the occupant's individual room. It may be configured to double as a card key.

  In this embodiment, the ID card 111 performs authentication necessary for a resident to receive a charging service for charging an electric vehicle (a vehicle owned by the user or a vehicle lent by car sharing). It is also used as a means. That is, in this embodiment, the ID card 111 is also used as a user authentication unit for a charging service provided by the charger 303 (master device) and the charger (slave device) 304.

  As described above, by using the ID card 111 that is associated with a specific resident 1: 1, the central control device 200 can provide information on the usage behavior of a specific resident's electric vehicle charging service, or Information about the electric vehicle for which the resident is charged can be stored as database information, and a plurality of electric vehicles can be charged efficiently and quickly using the database information.

It is assumed that information indicating whether or not the resident permits the supply of power to another load such as the exclusive unit 508 or the charger 304 connected to another electric vehicle is registered.

  If the main database as described above is prepared, the ID card 111 is presented to the card reader 102 of the console 103 or the card reader 3032 of the charger (base unit) 303, so that the central control device 200 is resident. When the room ID recorded on the ID card 111, which is the ID information of the person, is acquired, the article collection box assigned to the resident, for example, can be obtained by referring to the field ID field 1301 of FIG. 2 using the room ID. The ID (field 1302) and fields of pointers to other related databases (1303, 1304, 1305) can be identified.

  Further, by referring to the pointer storage fields 1303 and 1304, the storage area of the charging / power supply processing database as shown in FIG. 3 is specified, the data stored in the area is extracted and used, and the specific room ID is used. When a new charging service is implemented for a resident, the corresponding data in the charging / power supply processing database can be updated according to the contents.

  Next, the operation of the present system configured as described above will be described with reference to FIGS. 3 to 5 respectively show surplus power control, power supply control, and electric vehicle charge monitoring control performed by the central controller 200. FIG. 3 to 5 are stored in an external storage device (not shown) such as a ROM or an HDD of the central control device 200, for example, and a CPU (not shown) constituting the main control unit of the central control device 200, for example. It is executed by.

  The procedure of FIG. 3 shows the flow of surplus power control executed by the central controller 200. FIG. 3 shows control for monitoring the power generation amount of the solar cell panel 801 and charging the storage battery 701 with the surplus power. In step S201, whether or not there is surplus power available for charging the storage battery 701, for example, the output of the solar panel 801 and the power supply to the common unit load 500, the door exclusive unit 508, the chargers 303 and 304 of the electric vehicle, etc. By measuring the output state, it is determined whether there is surplus power available for charging the storage battery 701. If there is surplus power in the output of the solar cell panel 801, the power supply / reception path is switched using line switching means (not shown) such as a relay or an analog switch so that the solar cell panel 801 can charge the storage battery 701 in step S203. If there is no surplus in the power generation amount of the panel 801, the charging setting of the storage battery 701 is turned off, that is, the power supply path to the storage battery 701 is shut off (step S202).

  Note that FIG. 3 shows only the control related to the solar cell panel 801, but the same control can be performed when power generation means such as a wind power generator is used. Further, the charge amount of the storage battery 701 is monitored, and when there is no surplus in the output of the power generation means such as the solar battery panel 801 and the charge amount of the storage battery 701 is not sufficient, a commercial AC power source (or a cogeneration generator or the like) is used. A control routine for charging the storage battery 701 by a private generator may be incorporated. In this case, the output of the commercial AC power supply (or private generator) is converted into a voltage (AC / DC) by a converter installed in advance as required.

  FIG. 4 shows power feeding control using a sunshine sensor or a human sensor. As described above, in this system, a sunshine sensor or a human sensor is arranged at a predetermined position in the apartment house, and if these outputs are monitored (step S301), whether or not unnecessary power feeding is performed. It can be determined (step S302). For example, whether or not useless power is being supplied depending on the illuminance detected by the sunshine sensor (or the current time detected by the timer, etc.) and the manned / unmanned state detected by the human sensor. It is possible to determine whether or not (for example, whether or not the entrance lighting 501 is turned on unnecessarily).

  If unnecessary power feeding is detected in step S302, the central controller 200 records that fact in a database, and displays it as necessary (for example, a specific place such as the console 103 of the article receiving apparatus 100 or a manager's room). A warning or notification is made using a monitor or display arranged in step S303 (step S303), or power supply to the load is forcibly cut off as necessary. However, regarding whether or not to turn off unnecessary lighting of lighting fixtures or the like, the administrator performs setting registration in advance on the database (FIG. 2) managed by the central control device 200 (for example, using the console 103), It may be desirable to control whether or not to turn off unnecessary lighting according to the set state.

  The central controller 200 not only warns / displays the occurrence of unnecessary power supply as described above, but also sets the power consumption and usage status of each part of the common part of the power grid of the apartment house to each part of the power network ( It is possible to display according to the output of the current meter, etc., and to display advice such as an improvement plan of the power usage method using a display means such as the console 103. About this advice display, for example, when unnecessary power supply is not forcibly turned off, it is recommended to register unnecessary power supply forced OFF control by displaying the monthly cumulative time of unnecessary power supply recorded in the database and its power amount, It is conceivable to display a warning for unnecessary lighting such as lighting.

  The control unit of the article receiving device detects unnecessary power feeding to a load included in the power grid arranged in the apartment house, records information on occurrence of unnecessary power feeding in the database, and information on occurrence of unnecessary power feeding. Displayed by warning or display means.

  FIG. 5 shows a part related to electric power control except for a known part in the electric vehicle charging control in this system.

  Step S401 in FIG. 5 shows a known electric vehicle charging control. In step S401, the user (resident) sets an operation for setting a charging service performed by presenting the ID card 111 to the charger (master unit) 303 (or the console 103 of the article receiving apparatus 100) (for example, setting the charging time) 3), the database information (fields 1303, 1304, 1305 and database records indicated by these pointers) related to the electric vehicle charging in FIG. 3 is updated. At this time, the control value such as the charging current of the charger 304 and the data such as the (estimated) capacity of the battery of the electric vehicle are recorded in the database every moment. In addition, since a commercial AC power supply is used as the power source for charging the electric vehicle, here, the number of electric vehicles that are charged simultaneously so that the charging current does not exceed the contracted current amount of the housing complex when simultaneously charging a plurality of electric vehicles. The control which restricts is also performed.

  In step S402, it is determined whether or not there is a shortage in power to the common unit load 500, the door exclusive unit 508, the electric vehicle chargers 303 and 304, and the like. As a cause of such an event, it is conceivable that the commercial AC power supply fails (or the power generation amount of the solar cell panel 801 decreases due to conditions such as nighttime or bad weather). Such a situation can be detected by a sensor or the like provided in a required part of the power network as described above.

  In step S402, when such a power shortage condition occurs, charging of the electric vehicle being executed is first stopped. However, if the power shortage still occurs, the battery of the electric vehicle is removed after step S403. Control to supply power as a power source is performed.

  In step S403, an electric vehicle capable of supplying power to other loads (or the charger 304 connected to another electric vehicle) such as the common unit load 500 and the door exclusive unit 508 is searched. As described above, the central control device 200 records data such as the control value such as the charging current of the charger 304 and the (estimated) capacity of the battery of the electric vehicle in the database, and therefore corresponds to each electric vehicle being charged. By referring to the data, it is possible to search which of the electric vehicles whose outlets are connected to the charger 304 is in a state where power can be supplied to other loads.

  Furthermore, in the present embodiment, from the battery of the electric vehicle owned by the resident (or lent by car sharing) to the other registration load in the power control system in the registration information database of each house indicated by the pointer 1305 in FIG. Since the information on whether or not to permit the power supply of the vehicle is registered, the electric vehicle that is in a state where power can be supplied to the other load, the power supply to the other load is already received by the resident. Only vehicles that are licensed by are identified.

  In step S404, it is determined whether or not a vehicle in which power can be supplied to another load as described above and a vehicle for which power supply to the other load is permitted in advance by the resident has been searched. If there is even one vehicle to be operated, the process proceeds to step S405, and other loads such as the common unit load 500 and the door exclusive unit 508 are charged from the electric vehicle satisfying the above conditions (or other vehicles are charged). Power is supplied to the charger 304). At this time, conversion from direct current to alternating current and necessary voltage conversion are performed by the converter 803.

  As described above, even in a situation where power failure of commercial AC power supply or power shortage of power generation means or storage battery overlaps, the license information on power supply to other loads is pre-registered from the electric vehicle registered in the database. Power can be supplied to other loads included in the power supply / reception element in the power network. In the present embodiment, since control data and charging data relating to charging of the electric vehicle are recorded in the database, the occupant concerned with the electric vehicle (which is supplied with electric power to other loads by the control as shown in FIG. 5). ), The charging fee of the electric vehicle can be reduced or exempted at a predetermined rate according to the amount of power supplied or the time of power supply.

  As described above, the power control system of the present embodiment has a configuration in which the control unit of the article receiving device also serves as the power supply / reception control unit of the smart power control system or the control unit of the charging system of the electric vehicle. Therefore, the integration of the control circuit can significantly reduce the manufacturing cost of the system, and the data recorded in relation to the resident ID in the database essential for the control of the article receiving device in the apartment house such as an apartment is utilized. It is possible to optimally control the power supply of the power grid that includes the receipt of goods for postal items and parcels, the charging of electric vehicles, and the electric vehicle and its charger as power supply and reception elements.
