That is, different parking space identification information is assigned to each of the plurality of power feeders 13, and is transmitted from the right transmission unit 94 and the left transmission unit 95 provided in the power supply connector 72 of each power supply 13. The parking space identification information assigned to the power feeder 13 is superimposed on the right signal RS and the left signal LS. That is, if the power feeder 13 is different, the parking space identification information superimposed on the right signal RS and the left signal LS is different, but the parking space identification information superimposed on the right signal RS and the left signal LS in the same power feeder 13 are different. The overlapping parking space identification information is the same. Thereby, even when the right signal RS is simultaneously transmitted from the right transmission unit 94 provided in the power supply connector 72 of the plurality of power feeders 13, the receiver 12 is based on the parking space identification information superimposed on the right signal RS. Thus, it can be recognized whether the received right signal RS is transmitted from the right transmission unit 94 provided in the power supply connector 72 of any power supply 13. The same applies to the case where the left signal LS is simultaneously transmitted from the left transmitter 95 provided in the power connector 72 of the plurality of power feeders 13.

  The attitude sensor 96 is a sensor that detects the attitude of the power supply connector 72 when the power supply connector 72 is connected to the power supply port 201 of the vehicle. The attitude sensor 96 is used to check whether or not the power supply connector 72 connected to the power supply port 201 of the vehicle has a power supply connection attitude. As shown in FIG. 5A, the posture sensor 96 is provided inside the connection body portion 91 or the handle portion 92 of the power feeding connector 72. As the posture sensor 96, for example, an acceleration sensor or a detector (for example, a small sphere) that moves by gravity or buoyancy can be used.

  The power supply connection sensor 97 is a sensor that detects whether or not the power supply connector 72 is connected to the power supply port of the vehicle. The power supply connection sensor 97 is provided, for example, in the socket portion 93 or the like. Further, a display lamp 98 is provided on the outer surface of the power supply connector 72. The display lamp 98 is turned on during power supply and turned off when it is not.

  The power feeding cable 73 is a cable that connects the power feeder main body 71 and the power feeding connector 72. When power feeding is not performed and the power feeding connector 72 is attached to the power feeding connector storage unit 84 of the power feeder main body 71, the power feeding cable 73 is wound around a cable reel provided in the cable storage unit 85. On the other hand, when supplying power, the user holds the power supply connector 72 and pulls it lightly, whereby the cable reel is rotated by the force and the power supply cable 73 is pulled out. When the power supply connector 72 is connected to the power supply port provided on the side surface of the vehicle, the amount of pulling out of the power supply cable 73 increases. On the other hand, when the power feeding connector 72 is connected to the power feeding port provided on the front side or the rear side of the vehicle, the amount of the power feeding cable 73 drawn out is small.

(Power supply connector position detection and power supply conditions)
In FIG. 4, the power feeder 13 installed to supply power to the vehicle 200 parked in the one parking space 3 is arranged at a position corresponding to the one parking space 3 on the back side of the one parking space 3. Has been. Further, the receiver 12 that mainly detects the position of the power feeding connector 72 of the power feeder 13 is arranged at a position sandwiching the one parking space 3 where the vehicle 200 is parked, that is, the one It is the receiver 12 arrange | positioned at the right side toward the back side from the near side of the parking space 3 and the receiver 12 arrange | positioned at the left side from the near side of the said one parking space 3 toward the back side. The vehicle 200 is parked in the one parking space 3, and the power supply port of the vehicle 200 supplies power to the vehicle 13 that is installed to supply power to the vehicle parked in the one parking space 3. A connector 72 is connected, and the power supply connector 72 is in a power supply connection posture. Since the power supply port of the vehicle 200 opens in the right direction from the near side to the back side of the one parking space 3, the power supply connector 72 connected to the power supply port is connected to the one parking space 3. It is located on the right side from the front side to the back side.

  When power supply is started in such a state, the right signal RS is transmitted from the right transmission unit 94 provided in the power supply connector 72 connected to the power supply port, and the left signal LS is transmitted from the left transmission unit 95. The right signal RS is transmitted in the right direction toward the power supply port. On the other hand, the left signal LS is transmitted in the left direction toward the power supply port. As a result, the range in which the right signal RS is propagated with sufficient strength is the range surrounded by the one-dot chain line in FIG. 4, and the range in which the left signal LS is propagated with sufficient strength is enclosed by the broken line in FIG. Range. In this case, the receiver 12 arranged on the right side from the near side to the far side of the one parking space 3 receives the right signal RS. In addition, the receiver 12 may receive the left signal LS reflected on some object. As a result, in the receiver 12, the reception strength of the right signal RS is greater than the reception strength of the left signal LS. On the other hand, the receiver 12 arranged immediately on the left side from the near side to the far side of the one parking space 3 may receive the right signal RS and the left signal LS reflected by any object, Even if they are received, their reception strength is extremely small, so it can be said that neither the right signal RS nor the left signal LS is substantially received.

  As described above, in the receiver 12 arranged on the right side from the near side to the far side of the one parking space 3, the reception strength of the right signal RS is larger than the reception strength of the left signal LS, and the one parking When the receiver 12 arranged on the left side from the near side of the space 3 to the far side does not substantially receive the right signal RS and the left signal LS, as shown in FIG. The power feeding connector 72 of the power feeder 13 installed to feed power to the vehicle 200 parked in the space 3 is in a normal state connected to the power feeding port of the vehicle 200 parked in the one parking space 3. It can be judged.

  On the other hand, when the power supply port is installed on the left side of the vehicle body 200, the receiver 12 that mainly detects the position of the power supply connector 72 of the power supply 13 is similar to the above in which the vehicle 200 is parked. It is arranged at a position sandwiching one parking space 3. The vehicle 200 is parked in the one parking space 3, and the power supply port of the vehicle 200 supplies power to the vehicle 13 that is installed to supply power to the vehicle parked in the one parking space 3. A connector 72 is connected, and the power supply connector 72 is in a power supply connection posture. Since the power supply port of the vehicle 200 is opened in the left direction from the front side to the back side of the one parking space 3, the power supply connector 72 connected to the power supply port is connected to the one parking space 3. It is located on the left side from the near side to the far side.

  When power supply is started in such a state, the right signal RS is transmitted from the right transmission unit 94 provided in the power supply connector 72 connected to the power supply port, and the left signal LS is transmitted from the left transmission unit 95. The right signal RS is transmitted in the right direction toward the power supply port, and the left signal LS is transmitted in the left direction toward the power supply port. As a result, the range in which the right signal RS is propagated with sufficient strength is close to the front of the vehicle body 200 (the front side of the one parking space 3) as in the range surrounded by the dotted line in FIG. The range in which is propagated with sufficient strength is close to the rear of the vehicle body 200 (from the front side to the back side of the one parking space 3), similarly to the range surrounded by the one-dot chain line in FIG. In this case, the receiver 12 arranged on the left side from the near side to the far side of the one parking space 3 receives the left signal LS. In addition, the receiver 12 may receive the right signal RS reflected by some object. As a result, in the receiver 12, the reception strength of the left signal LS is greater than the reception strength of the right signal RS. On the other hand, the receiver 12 arranged on the right side from the near side to the far side of the one parking space 3 may receive the left signal LS and the right signal RS reflected on any object, Even if they are received, their reception strength is extremely small. Therefore, it can be said that neither the left signal LS nor the right signal RS is substantially received.

  As described above, in the receiver 12 disposed immediately on the left side from the near side to the far side of the one parking space 3, the reception intensity of the left signal LS is larger than the reception intensity of the right signal RS, and the one parking area When the receiver 12 disposed on the right side from the near side of the space 3 toward the back side substantially receives neither the left signal LS nor the right signal RS, the vehicle 200 parked in the one parking space 3 It can be determined that the power supply connector 72 of the power supply device 13 installed to supply power to the vehicle is in a normal state connected to the power supply port of the vehicle 200 parked in the one parking space 3.

In contrast, for example, when the power supply connector 72 of the power supply 13 installed to supply power to the vehicle 200 parked in one parking space 3 is connected to the vehicle body 300 adjacent to the vehicle body 200 shown in FIG. The combination of the receivers 12 to be received and the difference in reception intensity between the right signal RS and the left signal LS (difference in parking space identification information) is installed to supply power to the vehicle 200 parked in the one parking space 3. It can be determined that the power supply connector 72 of the power supply device 13 connected is connected to the power supply port of the vehicle 300 parked in the other parking space 3 adjacent to the right.

  As described above, the parking management system 1 determines whether or not the connection of the power supply connector 72 to the vehicle power supply port is normal by detecting the position of the power supply connector 72 connected to the power supply port of the vehicle. In this detection / judgment process, the two receivers 12 arranged on the right side and the right side from the front side to the back side of the one parking space 3 correspond to the one parking space 3. For the right signal RS and the left signal LS transmitted from the right transmission unit 94 and the left transmission unit 95 provided in the power supply connector 72 of the power supply 13 arranged at the position, the above detection or determination of the reception intensity is performed. This is based on the parking space identification information superimposed on the right signal RS and the left signal LS. The right signal RS and the left signal LS are transmitted to the right transmission unit 94 provided on the other power feeding connector 72 and the left signal LS. This is realized by discriminating from other right signals RS and other left signals LS transmitted from the transmitter 95. Further, the receiver 12 identifies the right signal RS and the left signal LS based on the difference between the frequency of the right signal RS and the frequency of the left signal LS.

  Further, in the parking management system 1, the position of the power supply connector 72 connected to the power supply port of the vehicle is transmitted in the right direction toward the power supply port in the right direction and in the left direction toward the power supply port. Although detection is performed using the left signal LS, this detection is based on the premise that the power supply connector 72 connected to the power supply port of the vehicle is in the power supply connection posture. As in this embodiment, the connection body 91 and the handle 92 of the power supply connector 72 rotate freely with respect to the socket 93 connected to the power supply port, and the power is naturally supplied by the weight of the handle 92 and the power supply cable 73. In the case of the configuration in the connection posture, the connection body portion 91 and the handle portion 92 can be rotated 180 degrees against gravity while the socket portion 93 is connected to the power supply port. Thus, when the power feeding connector 72 is rotated 180 degrees from the power feeding connection posture, the arrangement relationship between the right transmission unit 94 and the left transmission unit 95 with respect to the receiver 12 is reversed, and the right signal RS and the left signal LS are replaced with each other. End up. As a result, the power supply condition can be satisfied even in an unauthorized connection state. However, in the parking management system 1, when such a connection of the power supply connector 72 is connected in an unauthorized direction, the posture sensor 96 prevents unauthorized power supply.

(Power supply device)
As shown in FIGS. 1, 2, and 4, the power supply device 15 is disposed at a substantially intermediate position between the plurality of parking spaces 3. The power supply device 15 has a relatively tall casing 51, and a power pole (not shown) is installed beside it, and a power line 52 connected to a general commercial power supply source outside the parking lot is drawn from the upper side. It is. A display lamp 53 is provided on the front surface of the casing 51 to indicate whether or not it is operating (power is being supplied to the power feeder 13). Further, the power supply device 15 is connected to the fee settlement machine 11 via the embedded wiring 16. Further, a plurality of embedded power supply lines 17 are wired from the power supply device 15 to each power supply 13. As shown in FIG. 3, the power supply device 15 includes an external communication unit 54 that performs serial communication with the fee settlement machine 11, and further includes a control unit 55 and a power distribution unit 56. The buried power supply lines 17 to the power feeders 13 are radiated as many as the number of power feeders 13. The embedded power supply line 17 from the power distribution unit 56 also includes a power supply line and a control line. Power is supplied to the power supply unit 82 of each power supply 13 and the power supply state of each power supply 13 is changed to a power supply device. It can also be monitored on the 15 side.

(Operation of parking fee adjustment machine and flap board)
FIG. 6 shows the operation of the charge settlement machine 11 in the parking management system.

<Main operation>
In FIG. 6, when a vehicle enters the empty parking space 3, the vehicle sensor 7 embedded in the parking space 3 detects that fact and turns ON (step S 1: Y). Starts measuring the parking time. If the vehicle has not entered the empty parking space 3, the routine is continuously monitored (step S1: N). Subsequently, the fee settlement machine 11 transmits a power storage lock release command to the receiver 12 corresponding to the parking space 3. Thereby, the lock release control signal is transmitted from the receiver 12 that has received the lock release command to the lock control unit 88, and the lock of the power supply connector 72 is released (step S2). As a result, the user can remove the power supply connector 72 from the power supply connector storage unit 84. Subsequently, the fee settlement machine 11 determines whether or not the warehousing service time has elapsed since the start of the parking time measurement (step S3). The warehousing service time, after entering the parking space 3, takes into account that there is a vehicle leaving the parking space 3 in a very short time, and waits without starting the flap plate 6 after starting the parking time measurement The waiting time as the warehousing service time is set to about 3 to 5 minutes, for example.

  When the warehousing service time has elapsed (step S3: Y), the fee adjustment machine 11 controls the flap device 5 provided in the parking space 3 to raise (stand) the flap plate 6 (step S4). Then, it waits for a user to settle about the vehicle parked in the said parking space 3 (step S5). When payment by the user is completed (step S5: Y), the fee adjustment machine 11 controls the flap device 5 provided in the parking space 3 to lower (fall down) the flap plate 6 (step S6). . Subsequently, when the vehicle leaves the parking space 3, the vehicle sensor 7 embedded in the parking space 3 detects that fact and turns OFF (step S7: Y). If the power supply connector 72 is not locked to the power supply connector storage unit 84 by the lock control unit 88 at this time, the fee settlement machine 11 transmits a lock command to the receiver 12 corresponding to the parking space 3. Thus, a lock control signal is transmitted from the receiver 12 that has received the lock command to the lock control unit 88, and the power supply connector 72 is locked to the power supply connector storage unit 84 (step S8). As a result, the process ends, but immediately after that, the process starts again from step S1.

  Further, the fee settlement machine 11 does not remove the power supply connector 72 of the power supply 13 corresponding to the parking space 3 from the power supply connector storage unit 84 before the warehousing service time elapses (step S3: N) ( Step S10: N) When the vehicle sensor 7 is turned off and it is detected that the vehicle has left the parking space 3 (Step S11: N), a lock command is transmitted to the receiver 12. Thereby, the power feeding connector 72 is locked (step S12). As a result, the process ends, but immediately after that, the process starts again from step S1.

<Exit time limit operation (continuous reuse)>
On the other hand, it is detected that the vehicle has left the parking space 3 without turning off the vehicle sensor 7 even though the settlement is finished (step S5) and the flap plate 6 is lowered (step S6). If the delivery limit time has elapsed in the absence (step S7: N) state (step S9: Y), the process returns to step S4, and the fee settlement machine 11 raises the flap plate 6 again. In consideration of the fact that it is necessary to charge again when the vehicle has been parked for a long time after the completion of the payment, the delivery limit time is lowered once and then raised again. For example, about 5 to 10 minutes. If the process returns to step S4 in this routine, parking time measurement is started for recharging.

<Operation only for parking use>
The main operation is a mere parking operation without power supply or a warehousing operation before elapse of the warehousing service time, although the power supply connector 72 is unlocked in step S2. Therefore, the operation of locking the power supply connector 72 to the power supply connector storage unit 84 in step S8 is performed when the power supply connector is not removed from the power supply connector storage unit 84 after a predetermined time has elapsed since the lock of the power supply connector 72 was released. May lock in order to prevent unauthorized use by vehicles parked in other parking spaces 3.

<Power supply detection operation>
The user removes the power feeding connector 72 of the power feeder 13 corresponding to the parking space 3 from the power feeding connector storage unit 84 before the warehousing service time elapses after the parking time measurement is started in step S2. When connected to the power supply port, the power supply connection sensor 97 provided in the power supply connector 72 detects that fact and is turned on (step S10: Y). 3 is controlled to raise the flap plate 6 (step S4). In addition, when the user removes the power supply connector 72 from the power supply connector storage unit 84 and connects it to the power supply port of the vehicle after the warehousing service time has elapsed and before payment, the power supply connector 72 is provided. The power supply connection sensor 97 detects that fact and turns on (step S13: Y), and the process proceeds to step S14.

<Power supply control operation>
When the power feeding connection sensor 97 detects that the power feeding connector 72 of the power feeding machine 13 corresponding to the parking space 3 is connected to the power feeding port of the vehicle (step S13: Y), the power feeding connected to the power feeding port of the vehicle. The position of the connector 72 is detected to determine whether or not the connection of the power feeding connector 72 is normal. That is, first, the receiver 12 that detects the position of the power supply connector 72 in response to the detection of the power supply connection sensor 97 performs the right transmission unit 94 and the left transmission provided in the power supply connector 72 via the power supply control unit 67. The unit 95 is controlled to transmit the right signal RS and the left signal LS from the right transmitter 94 and the left transmitter 95, respectively (step S14). Then, the receiver 12 measures the reception intensity of the right signal RS and the left signal LS received by the receiving unit 65, and determines whether or not the above-described power supply condition is satisfied. Further, the receiver 12 receives the detection result of the attitude sensor 96 provided in the power supply connector 72, and determines whether or not the power supply connector 72 is in the power supply connection attitude based on the detection result (step). S15). When the power supply condition is satisfied and the power supply connector 72 is in the power supply connection posture (step S15: Y), the receiver 12 controls the right transmitter 94 and the left transmitter 95 to control the right. After the transmission of the signal RS and the left signal LS is stopped (step S16), the power supply unit 82 of the power supply 13 is controlled to enable power supply, and at the same time, the receiver 12 sends a power supply request to the fee settlement machine 11. Output (step S17). Note that although it is not necessary to stop the transmission of the right signal RS and the left signal LS in step S16, energy consumption can be suppressed by stopping the transmission, and the position of the power feeding connector 72 in another parking space 3 can be detected. Noise reduction in processing can be achieved. Instead of stopping completely, the transmission stop and transmission may be repeated at regular intervals.

  Subsequently, when the power supply control unit 67 determines that the battery of the vehicle is fully charged (step S18: Y), or the user removes the power supply connector 72 from the power supply port of the vehicle, and the power supply connection sensor 97 indicates that. When detected (step S25: Y), the receiver 12 controls the power supply unit 82 to output a power supply request stop to the fee settlement machine 11 (step S19).

  On the other hand, when the power supply condition is not satisfied, or when the posture of the power supply connector 72 is not the power supply connection posture (step S15: N), the receiver 12 settles a charge requesting for displaying an error message, for example. To the machine 11. In response to this, the fee settlement machine 11 displays an error message on the display 22 informing that power is not supplied. If the power supply condition is not satisfied, or if the power supply connector 72 is not in the power supply connection position for a predetermined time limit before starting power supply (step S23: Y), the receiver 12 receives the right signal and the left signal. Is stopped (step S24).

  On the other hand, after outputting the power supply request stop in step S19, or after the time limit before starting power supply has elapsed without power supply being started in step S23, the fee settlement machine 11 has confirmed that the power supply connector 72 is mounted on the power supply connector storage unit 84. It is determined whether or not (step S20). Specifically, as described above, based on the detection signal output from the detection switch, the receiver 12 determines whether or not the power supply connector 72 is attached, and transmits the determination result to the fee settlement machine 11. Based on this, the fee settlement machine 11 recognizes whether or not the power feeding connector 72 is attached.

  After the user performs power supply using the power supply connector 72 or when the power supply connector 72 is removed from the power supply connector storage unit 84 but is not supplied with power, the user connects the power supply connector 72 to the power supply connector 72. If the power supply connector 72 is not attached to the storage unit 84 and returned to the original storage position, the parking fee or the power supply fee cannot be settled. When the user attaches the power supply connector 72 to the power supply connector storage unit 84, the fee settlement machine 11 determines that the power supply connector 72 is attached to the power supply connector storage unit 84 (step S20: Y), and receives it. A lock command is transmitted to the machine 12. Thereby, the lock control signal is transmitted from the receiver 12 that has received the lock command to the lock control unit 88, and the power supply connector 72 is locked (step S21). Thereafter, the process proceeds to step S5.

  On the other hand, when the user tries to perform payment without attaching the power supply connector 72 to the power supply connector storage unit 84, the fee settlement machine 11 recognizes that (step S20: N, step S26: Y), For example, an error message such as “The power feeding connector has not been returned” is displayed on the display unit, or the sound is output from the speaker (step S27).

  In each of the steps described above, a part of the operation / determination is performed by the receiver 12, but may be performed collectively by the fee settlement machine 11.

(User's fee settlement machine operation)
FIG. 7 is an explanatory diagram showing an example of the display screen 22a and the operation keys 23 in the display 22 of the fee settlement machine 11 according to the embodiment of the present invention. FIG. 7 illustrates a case where the user directly inputs the power supply mode (rapid / medium / expected). FIG. 7A shows a screen in a standby state. The user selects and operates the operation key 23 from this state. In the following description, the user who parks the vehicle in the parking space 3 connects the power supply connector 72 to the vehicle as described above, and the flap plate 6 has already been operated. It is assumed that the power supply request output has been achieved. At this time, the user does not pay immediately, but the guidance is displayed on the display screen 22a so as to first press the power supply key 23g or input the parking space number using the numeric keypad 23a. Here, it is assumed that the parking space number where the user's own vehicle is parked is first depressed using the numeric keypad 23a.

  FIG. 7 (2) shows the display state of the display screen 22a transitioned to when the number assigned to the numeric keypad 23a is pressed with “2” or “002” corresponding to the parking space number “2”. In this state, as shown in the guidance on the display screen 22a, the user presses one of the operation keys 23 of the settlement key 23b, the reception ticket key 23d, and the power supply key 23g. When the power supply key 23g is pressed before the parking space number in the standby state of FIG. 7 (1), a display without the lower half of the display screen 22a shown in FIG. 7 (2) is output. In the display state, the parking space number may be pressed and input with the numeric keypad 23a.

  Next, in FIG. 7 (3), the screen is changed to a screen for designating the power supply mode, and rapid power supply, medium speed power supply, and sequential power supply can be selected by the number of the numeric keypad 23a. A cancel key 23e is associated with the return operation. When the cancel key 23e is pressed for this return operation, the CPU 28 detects that fact and recognizes that the cancel key 23e is not pressed for canceling the settlement at the time of normal settlement.

  Further, in FIG. 7 (4), the screen changes to a screen for confirming the power supply fee in accordance with the designation of power supply, and in the case of rapid power supply, it is displayed that it is 1000 yen per 10 minutes. The user presses the registration key 23f assigned as a decision when selecting rapid power feeding, and presses the cancel key 23e when returning. Similarly, although not shown in the drawing, charge guidance such as 800 yen per 10 minutes for medium-speed power supply and 500 yen per 10 minutes for expected power supply is made to allow the user to select whether to decide. In addition, although the charge per hour is used for the power supply function, it is possible to adopt a gradual charge system for the separately supplied power amount Wh. The unit price per unit time can be varied according to the type of power supply (power supply mode).

  Here, the rapid power feeding means that the power feeding is performed preferentially without being influenced by the designation of the power feeding state of the parked vehicle in the other parking space 3 apart from the charging speed such as “fast charging” described in the prior art. For example, if there is a rapid power feeding vehicle first, the power feeding is started after the power feeding of the vehicle is completed. The medium-speed power supply is a condition that if a vehicle for rapid power supply comes later, the power is preferentially supplied, and then power is supplied. Further, the event power supply is a condition that, depending on circumstances, the power supply may be delayed after the power supply of another vehicle. Such designation of priorities is an example, and can be set in consideration of various conditions such as facility installation environment conditions (area, location <city area, department store, etc.) and the number of contractors.

  FIG. 8 is an explanatory diagram of the display screen 22a and the operation keys 23 of the fee settlement machine 11 according to another embodiment of the present invention. FIG. 8 illustrates a case where the user understands (selects) and inputs the power supply mode (rapid / medium speed / result) calculated and presented by the fee settlement machine 11 in consideration of the power supply mode of other vehicles. To do. FIG. 8 (1) shows a screen in a standby state, which is the same as FIG. 7 (1), and the user selects and operates the operation key 23 from this state. The user who parked the vehicle connects the power supply connector 72 to the vehicle, and the flap plate 6 has already been raised and the power supply request output described above has been made. At this time, the user does not pay immediately, but there is a guidance display on the display screen 22a so that the user first presses the power supply key 23g or inputs the parking space number. Is pressed.

  FIG. 8 (2) is the same as FIG. 7 (2) described above, and shows the display state of the display screen 22a transitioned to when “2” or “002” corresponding to the parking space number “2” is pressed. In this state, as shown in the guidance on the display screen 22a, the user presses one of the operation keys 23 of the settlement key 23b, the reception ticket key 23d, and the power supply key 23g. If the power supply key 23g is pressed first in FIG. 8A, the power supply key 23g is pressed before the parking space number in the standby state shown in FIG. The display without the lower half of the display screen 22a shown in FIG. 8 (2) is output, and the parking space number may be pressed and input in the same manner with the numeric keypad 23a.

  Next, in FIG. 8 (3), the screen changes to a screen for specifying the scheduled parking time, and the six-stage scheduled parking time from 1 hour (1h) to 5 hours (5h) or more is obtained using the numeric keypad 23a. It can be specified (selection input). A cancel key 23e is associated with the return operation.

  Further, in FIG. 8 (4), the screen transits to a screen for confirming the power supply mode and the power supply fee with the designation of the scheduled parking time. For example, in FIG. 8 (3), when “1” of the numeric keypad 23a for which the time designation is within 1h is pressed, the fee settlement machine 11 determines that rapid power feeding is necessary from data of other scheduled times described later, and every 10 minutes. Indicates that it is 1000 yen. The user confirms the unit price (power supply mode) on the display screen 22a. If the unit price is acceptable, the user presses the registration key 23f corresponding to the determination. Press 23e.

  In this case, when the planned parking time is short, the control circuit of the power supply unit 82 of the power supply 13 (for example, also used by the lock control unit 88) determines in advance how much power supply time is required for the vehicle and receives the data. Which parking is performed in the CPU 28 of the fee settlement machine 11 based on the scheduled parking time, the time required for power supply, or the amount of power required for power supply, which is transmitted to the price settlement machine 11 via the machine 12 and stored in the memory 29 of the price settlement machine 11 It is determined whether or not power supply should be performed preferentially from space 3.

  By the way, in the said embodiment, although the case where the scheduled parking time of the preset range was selected and input with the operation key 23 was demonstrated, it is comprised so that a planned parking time may be directly input per time unit (for example, 3 hours). You may do it. In addition to the selection input or direct input of the scheduled parking time described above, the planned delivery time is directly input (for example, 17:30) or a certain range (for example, AM / PM (13: 00-17: 00) / Night ( 17-23) · You may select and input at midnight (23-6).

  Moreover, in the said embodiment, although the scheduled parking time was input as time required for electric power feeding use, for example, the electric power feeding use which is electric power feeding amount similarly to oil supply amount designation | designated (for example, 2000 yen) by gasoline refueling The time designation (for example, 1 hour) and the scheduled parking time designation (for example, 3 hours) can be directly input (or selectively input) independently.

  In addition, the time required for power supply can be used when using the short-time power supply mode that desires power supply shorter than the set power supply use time and the long-time power supply mode that allows power supply longer than the set power supply use time. Applied. This short-time power supply mode and long-time power supply mode can be used when you want to use the power supply amount as a reference.For example, if you specify the long-time power supply mode, you can continue to park even after the scheduled parking time has passed. As long as the power supply is full, power supply can be continued until full power supply is achieved.

  In this case, the charge settlement machine 11 is set with different power supply usage charge unit rates in the short-time power supply mode and the long-time power supply mode, in addition to the above-described rapid, medium-speed, and sequential power supply modes. For example, in the short-time power supply mode, it is set to the same amount as the rapid power supply mode (for example, 1000 yen per 10 minutes), and in the long-time power supply mode, it is set to the same amount as the medium-speed power supply mode (for example, 800 yen per 10 minutes). ). Therefore, the inventory database shown in FIG. 9 stores data necessary to allow these various modes.

  FIG. 9 is an explanatory diagram of the on-board database according to the embodiment of the present invention, in which the on-board situation corresponding to each of the parking spaces 3 is recorded. This database is stored in the memory 29 of the fee settlement machine 11 and is sequentially rewritten by loading / unloading vehicles and operations on the fee settlement machine 11. The contents of the in-vehicle database include the entry date and time, scheduled parking time, scheduled delivery date and time, power supply amount, power supply mode, power supply unit price, parking unit price, receipt ticket availability, etc. From the scheduled delivery date and time, the fee settlement machine 11 can instantaneously calculate the power supply mode and check the power supply mode on the screen of FIG.

  For users who park and leave the power supply connector 72 and leave without operating the fee settlement machine 11, it is effective to use medium speed charging or automatically select parking time 2 to 3h as a default condition. Yes, as long as the conditions are described separately on a signboard in the parking lot.

  FIG. 10 is a block diagram illustrating the function of the CPU 28 (FIG. 10 (1)) of the fee settlement machine 11 and the function of the control unit 55 (FIG. 10 (2)) of the power supply device 15 according to the embodiment of the present invention. Yes, the above description is illustrated. The functions of the control unit 55 shown here are only functions related to the features of the present invention, and in particular, the overall fee settlement function is omitted in the fee settlement machine 11. For the power supply device 15, there is a case where a method of monitoring the power supply state of the vehicle battery with the power supply connector 72 of the power supply device 13 or a current sensor or a temperature sensor installed inside the battery may be adopted. Any of these parts corresponds to the power supply current state reception unit, the power supply required power amount and the remaining time are calculated, and the power distribution determination unit appropriately determines the switching of power distribution and the combination of power distribution.

  Specifically, as shown in FIG. 10 (1), the CPU 28 of the fee settlement machine 11 accepts the power feeding mode from among the rapid power feeding, the medium speed power feeding, and the sequential power feeding, and receives the power feeding mode. From the sensor state of the power supply connector 72 from the machine 12, the usage state is received by the receiver sensor state receiving unit 44, and the priority of power supply is determined from the power supply mode of the vehicle received first and the power supply mode of the vehicle received later. The power supply instruction output unit 46 determines which power supply connector 72 is supplied with power based on the priority determination result.

  As shown in FIG. 10 (2), the control unit 55 of the power supply device 15 receives the power supply instruction output from the fee settlement machine 11 by the power supply instruction reception unit 47, and the current power supply current state is changed to the power supply current state. After confirming with the reception unit 48, a power distribution destination to be distributed to which power feeder 13 is determined by the power distribution determination unit 49, and a power distribution instruction is output to the power feeder 13 by the power distribution instruction output unit 50.

  As described above, the power supply device 15 according to the embodiment of the present invention can efficiently perform time-sharing with respect to a maximum of eight vehicles even if the power supply device 15 has only the power supply capability for two vehicles at the same time. By supplying power while using the power supply equipment with low power capacity effectively, it is possible to fully use the planned parking time (or scheduled delivery time) together with changing the charge according to the user's needs. The main point is to supply power while using it. For this purpose, a power distribution switching control signal is transmitted from the fee settlement machine 11 to the power supply device 15 so as to finely control power supply switching. In accordance with the control signal, the power supply device 15 supplies power to the desired power feeder 13.

  In the parking management system provided with the power supply device 15, the power feeder 13, the fee settlement machine 11, and the like of the embodiment of the present invention configured as described above, the power feeding connectors 72 are provided by the number of parking spaces 3. In addition, there is no need to wait for the turn to wait for the power supply connector 72 to be free. Also, even if a vehicle that has already been powered is parked as it is, it is reasonable to meet the needs of the user without adopting an unreasonable fee system that penalizes it and forces it to leave. Charges can be set, leading to improved utilization.

  Further, the present invention is further developed so that the power supply completion time is calculated in advance and displayed on the charge settlement machine 11, or the charge is changed depending on the power supply congestion, or the mobile phone of the user in the contract vehicle in which the power supply completion is separately registered. Various applications are possible, such as sending to an e-mail address, copying the on-board database to an external server, checking the power supply status on the Web, or changing the power supply mode from the Web.

  Moreover, in the Example of this invention, although the vehicle parked in the adjacent parking space 3 detects the case where it electrically feeds using the electric power feeding connector 72 for the adjacent parking space 3, the fraud prevention means is taken. The claims of the present invention may be realized without particularly taking this fraud prevention means, and it is sufficient that a separate person is provided or fraud is detected by a surveillance camera.

  Furthermore, in the embodiment of the present invention, in the individual lock type (flap type) parking lot, the case where the power supply usage fee and the parking fee are added together and settled by the fee settlement machine 11 is described. The present invention can be implemented in the same manner even in a parking lot in which a power supply connector 72 is provided for each cage in the parking lot and power is selectively distributed to each.

  In addition, for example, in a gated parking lot, the parking fee is settled by a fee settlement machine 11 installed near the exit, and the power supply fee is set up for a dedicated fee set up near a specific parking space 3 where a power supply facility is installed. Needless to say, this is a technology that can be implemented even in a business form in which a plurality of power supply connectors 72 are distributed and controlled by a small number of fee settlement machines 11 in a system that pays with the machine 11.

  Moreover, in such a gate type parking lot, the flap apparatus 5 is not often installed. For this reason, a parking ticket issuing machine and a vehicle identification device (for example, a license plate reader) are installed near the entrance gate. In addition, a vehicle identification device is also installed in each parking space 3 so that the fee settlement machine 11 can identify a vehicle when performing a designation operation such as a power feeding mode. Further, a fee settlement machine 11 and a vehicle identification device are installed near the exit gate. At this time, in the case of a parking lot provided adjacent to or apart from a building such as the large-scale store described above, a fee settlement machine 11 for performing settlement in advance can also be installed near the entrance of the building.

  In such a gate-type parking lot, an identification number such as a vehicle number plate read by a vehicle identification device installed near the entrance gate is recorded on a parking card issued by a ticketing machine together with a warehousing time, etc. The power supply mode is recorded on the card, and then the power is supplied. The settlement at the fee settlement machine 11 installed near the exit gate or the settlement at the price settlement machine 11 for pre-payment installed near the building entrance is confirmed. If this happens, open the exit gate and allow the shipment.

  In the well-known toll parking lot, by changing the parking unit price per unit time between daytime and nighttime, it is possible to improve nighttime usage efficiency, which is expected to be cheap and long-time use per unit time. There is.

  On the other hand, the unit price of electricity is often changed between the daytime when the usage is large and the night when the usage is low. Therefore, if the parking time of the user who uses parking and power supply is at night, not only the parking fee per unit time but also the power supply fee can be set low, which can contribute to the improvement of the usage service, The utilization efficiency of the parking space 3 can be improved.

  It should be noted that the present invention can be appropriately changed without departing from the spirit or idea of the invention which can be read from the claims and the entire specification, and the vehicle power feeding system and the parking management system accompanied by such a change are also described in this document. It is included in the technical idea of the invention.

  The technology of the present invention can be applied to a parking lot in which a power feeding device is installed in an individual lock type parking lot provided with an exit prevention device for each individual parking space 3, in particular, to other types of parking lots as well as individual lock type parking lots, Furthermore, it is expected to be used also in a power supply fee collection device provided with a power supply device. Moreover, the present invention can be applied to a parking and charging device such as a parking device for an electric motorcycle having a similar form and a charging device for an electrically assisted bicycle.
