  Note that the type, shape, and quantity of the power plug insertion port, the type and quantity of power supplied to the power plug insertion port, and the number of plug receptacles are not limited to those of the first embodiment. For example, the power supplied to the power plug outlet may be a single layer 200V. The power plug outlet may be dedicated to an electric vehicle.

  Next, the anti-theft device 15 will be described. As shown in FIG. 7, the anti-theft device 15 includes electromagnetic relays 35 and 37, an anti-theft control device 39, a DC power supply 41, and connection terminals 43, 45 and 47 that lock the power supply line 25.

  The electromagnetic relay 35 turns on / off the power supply to the plug receiver 29c. When a DC power is supplied to the coil 35a and the coil 35a is excited, the mechanical contact 35b is closed and relaying is performed. Similarly, the electromagnetic relay 37 turns on / off the power supply to the plug receiver 29d. When the DC power is supplied to the coil 37a and the coil 37a is excited, the mechanical contact 37b is closed and relayed.

The electric circuit switch may be an SSR (solid state relay), a program relay, or the like. Although not shown, a protection circuit is provided for preventing the mechanical contact 35b and the mechanical contact 37b from being seized.

  The electromagnetic relay 35 described above is disposed in the middle of the feeder line 25a, and the electromagnetic relay 37 is disposed in the middle of the feeder line 25b. The power supply line 25a and the power supply line 25b constitute the individual electric circuit of the present invention. Incidentally, since the power supply line 25c can supply power to both the plug receptacles 29c and 29d, it is not an individual electric circuit of the present invention.

  The anti-theft control device 39 includes a CPU 49, a memory 51, power supply separation circuits 53 and 55, drivers 57 and 59, and a timer circuit 61. The CPU 49 outputs a command signal for operating / stopping the drivers 57 and 59 based on the authentication result of the identification information of the RFID tag read by the RFID read / write device 73 described later. The memory 51 stores a control program for controlling the electromagnetic relay 35 to prevent power theft.

  Of the above-described antitheft control device 39, the electronic circuit portion for preventing theft and the program for preventing theft constitute the theft prevention control means of the present invention. In addition, the electronic circuit portion for authenticating the identification information and the program for authenticating the identification information in the anti-theft control device 39 constitute the identification information authentication means of the present invention. The power theft prevention control means includes a power supply means, a power supply stop means, a power supply function, and a power supply stop function, as will be apparent from the control procedure described later.

The driver 59 excites the coil 37 a of the electromagnetic relay 35 based on the excitation signal from the power supply separation circuit 53. The electromagnetic relays 35 and 37 and the anti-theft control device 39 are connected to a DC power source 41.

  The outlet 13 includes a blade detection sensor 63 that detects the blade of the plug P1, and a blade detection sensor 65 that detects the blade of the grounded plug P2. The blade detection sensors 63 and 65 constitute an example of the blade detection means of the present invention. In the first embodiment, a photoelectric sensor is used as the blade detection unit. However, a capacitive sensor, a proximity sensor system, a limit switch, or the like may be used.

  The method of detecting the blade of the plug P1 and the blade of the plug P2 with the grounding electrode is a method of detecting indirectly, in addition to the method of directly detecting the blade of the plug P1 and the blade of the plug P2 with the grounding electrode. Also good. As an example of the indirectly detecting method, a movable part (not shown) is provided in the outlet 13, and when the plug P1 and the plug P2 with the ground electrode are inserted, the blade of the plug P1 and the blade of the plug P2 with the ground electrode are inserted. There is a method in which the movable part is movable, and there is a method of detecting the movable part with a sensor.

  Further, as shown in FIG. 2, the above-described anti-theft device 15 is provided with a setting changing means 67, and appropriately changes a key input allowable time T1, a plug set allowable time T2, and a power supply allowable time T3 described later. It is configured to be able to.

  In the first embodiment, the outlet 13 is installed outdoors, and the electromagnetic relays 35 and 37 are installed indoors. Further, since the power supply lines 25a and 25b drawn into the outlet 13 are directly drawn in from the indoor side, as long as power supply is stopped, power is not stolen from the electric path from the power source to the plug receptacles 29c and 29d. Further, the power supply line from the power source to the electromagnetic relays 35 and 37 may be stolen from the power supply line from the power source to the electromagnetic relays 35 and 37, as in the case where the power supply line is wired so as to be visible to a person who wants to steal power. Has no sides.

  As shown in FIG. 7, commercial power is supplied to the outlet device 11 described above via a breaker 69 and a thermal overcurrent relay 71. The single-phase AC 100V power output from the thermal overcurrent relay 71 is supplied to the plug receivers 29c and 29d via the electromagnetic relays 35 and 37 and the terminal block 29. On the other hand, a single-phase AC 100V power source output from the thermal overcurrent relay 71 is branched at the connection terminal 43 and connected to the DC power source 41 described above. The breaker 69 and the thermal overcurrent relay 71 described above are not included in the outlet device 11 of the present invention.

  Next, the input device 17 will be described. As shown in FIGS. 7 and 8, the input device 17 includes an RFID read / write device 75 that reads identification information of an RFID (Radio Frequency IDentification) tag 73 and an operation unit 77.

  The RFID tag 73 is a passive tag that operates using electromagnetic waves from the RFID read / write device 75 as an energy source by an electromagnetic induction method, and incorporates a processor portion with or without a processor, an EEPROM, an SRAM, or the like as a storage device. An IC chip 73a and a coil 73b formed of a conductive wire are provided. The RFID tag 73 is disposed on the mobile phone T. The arrangement mentioned here is a concept including built-in, mounting, fixing, and sticking. In addition to the mobile phone T, the RFID tag 73 may be disposed on a movable structure such as a car key, a card, a portable information terminal, a clock, and a stuffed toy, for example.

  The RFID read / write device 75 has a predetermined communication range (operation space) with respect to the RFID tag 73, and the RFID tag 73 disposed on the mobile phone T is brought close to the communication range, A device that reads and writes information (for example, identification information), and includes a microcomputer that controls an interface with the anti-theft control device 39, a control unit 75a that includes a dedicated IC that communicates with an RFID tag, and an antenna 75b. ing. The RFID read / write device 75 constitutes identification information reading means of the present invention. In the first embodiment, only one RFID read / write device 75 is used for the plurality of plug receivers 29c and 29d. After the identification information of the RFID tag 73 is read and authenticated within the communication range, the RFID tag 73 is placed outside the communication range.

  The RFID read / write device 75 and the RFID tag 77 are well-known techniques, and the identification information reading procedure is omitted. The reading of the identification information may be so-called mutual authentication from the viewpoint of security. The RFID tag 73 may function regardless of whether the cellular phone T is turned on. The RFID tag 73 sets a password by pressing a numeric key of the mobile phone T while the screen of the mobile phone T is displayed, and the entered password matches a predetermined password stored in the mobile phone T in advance. Only it may function.

  As shown in FIG. 8, the operation unit 77 includes a start button 77a, a setting completion button 77b, a stop button 77c, and a power supply lamp 77d. The start button 77a is a button for turning on power to the anti-theft control device 39 and starting control. The setting completion button 77b is used when the plug set of the plug P1 and the grounding electrode plug P2 (the action of selecting the power plug to be inserted and inserting the power plug) is completed within the plug set allowable time T2 described later. This button is pressed when it is desired to start an anti-theft control described later without waiting for the time T2. The stop button 77c is a button to be pressed in an emergency or when it is desired to stop using the outlet. The power supply lamp 77d is a lamp that informs the operator of the control state by color. The concept of the plug set (the action of selecting the power plug to be inserted and inserting the power plug) includes the case where the power plug is not inserted into any of the plug receptacles.

  Next, the identification information input allowable time T1, the plug set allowable time T2, the power supply allowable time T3, and the control reference point will be described.

  The identification information input allowable time T1 is an allowable time for the RFID read / write device 75 to read identification information. The plug set allowable time T2 is an allowable time until the anti-theft control is performed. The power supply allowable time T3 is an allowable time for power supply.

  The control reference point is a point that is used as a reference for performing anti-theft control that does not supply power even when a power plug is newly inserted after the control reference point. In the first embodiment, the plug set allowable time T2 ends. This is the control reference point. Details will be described in a control procedure described later.

If the antitheft control is specifically described, the following controls (1) to (3) can be performed.
(1) At the control reference point, power is supplied to the plug receptacle into which the power plug is inserted. However, when the power plug inserted in the plug receptacle is removed, the electromagnetic relay is controlled so as to stop the power supply.
(2) At the control reference point, the electromagnetic relay is controlled so that power is not supplied to the plug receptacle to which the power plug is not inserted.
(3) After the control reference point, the electromagnetic relay is controlled so that power is not supplied even if a new power plug is inserted.

  Next, the control procedure of the first embodiment will be described. FIG. 9 to FIG. 11 show an example of the control procedure of the outlet device 11 in the first embodiment.

  In step S10, the start button 77a of the operation unit 77 is pressed. The power supply lamp 17d is lit red.

  In step S20, identification information input allowable time T1, plug set allowable time T2, and power supply allowable time T3 are initialized. The timer circuit 61 starts timing.

  In step S30, it is determined whether or not the identification information input allowable time T1 has elapsed. If the identification information input allowable time T1 has elapsed, the process proceeds to step S210. If the identification information input allowable time T1 has not elapsed, the process proceeds to step S40.

  In step S40, the mobile phone T in which the RFID tag 73 is built is placed within the communication range (operation range) of the RFID read / write device 75, and an authentication operation is performed. After the operation, the process proceeds to step S50.

  In step S50, whether or not the identification information is authenticated is determined. If the identification information is authenticated, the process proceeds to step S60. If the identification information is not authenticated, the process proceeds to step S210.

  In step S60, the power supply lamp 17d is lit in green. It progresses to step S70 after control. When the identification information is authenticated and the power supply lamp 17d is lit in green, the mobile phone T on which the FID tag 73 is placed is placed outside the communication range (operation range) of the RFID read / write device 75.

  In step S70, it is determined whether the plug set allowable time T2 has elapsed. If it is within the plug set allowable time T2, the process proceeds to step S70. When the plug set allowable time T2 has elapsed, the process proceeds to step S80. Within the plug set allowable time T2, the plug P1 that requires power supply and the plug P2 with a ground electrode are inserted into the plug receivers 29c and 29d. Even if the plug set allowable time T2 has not elapsed after step S60, when the plug set is completed and the setting completion button 77b of the operation unit 77 is pressed, an interrupt process is immediately performed, and step 80 is performed. Proceed to

  In step S80, it is detected whether or not the plug P1 is inserted into the plug receiver 29c. If the blade detection sensor 63 detects the blade of the plug P1, the process proceeds to step S90. If the blade detection sensor 63 cannot detect the blade of the plug P1, the process proceeds to step S100.

  In step S90, the electromagnetic relay 35 is turned on. The CPU 49 outputs a command signal for exciting the coil 35 a of the electromagnetic relay 35, and excites the coil 35 a via the power supply separation circuit 53 and the driver 57. Usually, before execution of step S80, the coil 35a is in a non-excited state, and the coil 35a is controlled from a non-excited state to an excited state. At that time, the mechanical contact 35b is closed and power is supplied to the plug receiver 29c. After processing, the process proceeds to step S110.

  In step S100, the electromagnetic relay 35 is turned off. The CPU 49 outputs a command signal for bringing the coil 35 a of the electromagnetic relay 35 into a non-excited state, and puts the coil 35 a into a non-excited state via the power supply separation circuit 53 and the driver 57. Usually, before the execution of step S80, the coil 35a is in a non-excited state, so that the non-excited state of the coil 35a is maintained. Since the mechanical contact 35b is kept open, power is not supplied to the plug receiver 29c. After processing, the process proceeds to step S110.

  In step S110, it is detected whether or not the grounded electrode plug P2 is inserted into the plug receiver 29d. If the blade detection sensor 65 detects the blade of the plug P1, the process proceeds to step S120. If the blade detection sensor 65 cannot detect the blade of the plug P2 with the ground electrode, the process proceeds to step S130.

  In step S120, the electromagnetic relay 37 is turned on. The CPU 49 outputs a command signal for exciting the coil 37 a of the electromagnetic relay 37 and excites the coil 37 a via the power supply separation circuit 55 and the driver 59. Usually, before execution of step S110, the coil 37a is in a non-excited state, and the coil 37a is controlled from a non-excited state to an excited state. At that time, the mechanical contact 37b is closed and power is supplied to the plug receiver 29d. After processing, the process proceeds to step S140.

  In step S130, the electromagnetic relay 37 is turned off. The CPU 49 outputs a command signal for deactivating the coil 37a of the electromagnetic relay 37, and deenergizes the coil 37a via the power supply separation circuit 55 and the driver 59. Usually, before the execution of step S110, the coil 37a is in a non-excited state, so that the non-excited state of the coil 37a is maintained. Since the mechanical contact 37b is kept open, no power is supplied to the plug receiver 29d. After processing, the process proceeds to step S140.

  In step S140, it is determined whether or not the allowable power supply time T3 has elapsed. When the power supply allowable time T3 has elapsed, the process proceeds to step S210. If the power supply allowable time T3 has not elapsed, the process proceeds to step S150.

  In step S150, the power supply lamp 17d is lit red. After processing, the process proceeds to step S160.

  In step S160, it is detected whether or not the plug P1 and the ground electrode plug P2 are inserted. If neither the blade of the plug P1 nor the blade of the ground electrode plug P2 is detected, the process proceeds to step S210. When any one or more of the blade of the plug P1 and the blade of the plug P2 with the ground electrode is detected, the process proceeds to step S170.

  In step S170, it is detected whether or not the plug P1 is inserted. If the plug P1 is not detected, the process proceeds to step S180. If the plug P1 is detected, the process proceeds to step S190.

  In step S180, the electromagnetic relay 35 is turned off. The CPU 49 outputs a command signal for making the coil 35 a in a non-excited state, and puts the coil 35 a in a non-excited state via the power supply separation circuit 53 and the driver 57. If the coil 35a is in a non-excited state before execution of step S170, the non-excited state of the coil 35a is maintained. Since the mechanical contact 35b is kept open, power is not supplied to the plug receiver 29c. Before the execution of step S170, when the coil 35a is in the excited state, the coil 35a is controlled from the excited state to the non-excited state. At that time, the mechanical contact 35b is opened and the power supply to the plug receiver 29c is stopped. After processing, the process proceeds to step S190. Thereafter, power supply to the plug receptacle 29c is stopped until the control is completed.

  In step S190, it is detected whether or not the grounding electrode plug P2 is inserted. If the blade of the ground electrode plug P2 is not detected, the process proceeds to step S200. When the blade of the ground electrode plug P2 is detected, the process proceeds to step S140.

  In step S200, the electromagnetic relay 37 is turned off. The CPU 49 outputs a command signal for making the coil 37 a in a non-excited state, and puts the coil 37 a in a non-excited state via the power supply separation circuit 55 and the driver 59. If the coil 37a is in a non-excited state before execution of step S190, the non-excited state of the coil 37a is maintained. Since the mechanical contact 37b is kept open, no power is supplied to the plug receiver 29d. If the coil 37a is in an excited state before the execution of step S190, the coil 37a is controlled from the excited state to the non-excited state. At that time, the mechanical contact 37b is opened and the power supply to the plug receiver 29d is stopped. After processing, the process proceeds to step S140. Thereafter, power supply to the plug receiver 29d is stopped until the control is completed.

  In step S210, the electromagnetic relay 35 and the electromagnetic relay 37 are turned off. Further, the power supply lamp 77d is turned off. The CPU 49 outputs a command signal for bringing the coil 35 a into a non-excited state, and puts the coil 35 a of the electromagnetic relay 35 into a non-excited state via the power supply separation circuit 53 and the driver 57. Similarly, the CPU 49 outputs a command signal for setting the coil 37a in a non-excited state, and sets the coil 37a of the electromagnetic relay 37 in a non-excited state via the power supply separation circuit 55 and the driver 59. Normally, when the execution of step S210 is started, the coils 35a and 37a are in the non-excited state, so the non-excited state is maintained. Since the mechanical contacts 35b and 37b are kept open, power is not supplied to the plug receivers 29c and 29d. Note that branch control is performed from step S30, step S50, and step S140, and when step 210 is reached, the electromagnetic relay 35 and the electromagnetic relay 37 are controlled to immediately stop power feeding. After processing, the process proceeds to step S220.

  In step S220, the control ends. When the stop button 77c is pressed, interrupt control is performed, the electromagnetic relay 35 and the electromagnetic relay 37 are controlled, and power supply is immediately stopped.

According to the above control procedure, theft can be prevented as follows.
(1) If the identification information is not authenticated, power is not supplied to the plug receptacles 29c and 29d.
(2) When the control reference point is reached, power is supplied to the plug receivers 29c and 29d in accordance with the insertion status of the plug P1 and the plug P2 with ground electrode. Specifically, among the blade detection sensors 63 and 65, when the blade detection sensor 63 detects the blade of the plug P1, and the blade detection sensor 65 cannot detect the blade of the plug P2 with the ground electrode, the anti-theft control means However, the coil 35a of the electromagnetic relay 35 can be brought into an excited state and can be controlled to supply power only to the plug receiver 29c. Of the blade detection sensors 63 and 65, when the blade detection sensor 65 detects the blade of the plug P2 with the grounding electrode and the blade detection sensor 63 cannot detect the blade of the plug P1, the anti-theft control means controls the electromagnetic relay 37. It is possible to control so that the coil 37a is energized and power is supplied only to the plug receptacle 29d. When the blade detection sensors 63 and 65 detect the blade of the plug P1 and the blade of the plug P2 with the ground electrode, respectively, the anti-theft control means puts the coil 35a of the electromagnetic relay 35 and the coil 37a of the electromagnetic relay 37 into an excited state. Thus, it is possible to control to supply power to both the plug receivers 29c and 29d. When the blade detection sensors 63 and 65 cannot detect the blade of the plug P1 and the blade of the plug P2 with the ground electrode, respectively, the anti-theft control means de-energizes the coil 35a of the electromagnetic relay 35 and the coil 37a of the electromagnetic relay 37. Thus, it is possible to control not to supply power to both plug receptacles 29c and 29d.
(3) When the plug set allowable time T2 elapses, the excitation state or the non-excitation state of the coil 35a and the coil 37a is maintained. When the blade detection sensor 63 detects the blade of the plug P1 and cannot detect the blade of the plug P1, the coil 35a of the electromagnetic relay 35 is brought into a non-excited state assuming that the plug P1 has been removed. The power supply to the plug receiver 29c can be stopped. Further, when the blade detection sensor 65 detects the blade of the plug P2 with the ground electrode and becomes unable to detect the blade of the plug P2 with the ground electrode, it is assumed that the plug P2 with the ground electrode is removed and the electromagnetic relay The coil 37a of 37 can be de-energized, and thereafter the power supply to the plug receiver 29d can be stopped.
(4) After the plug set allowable time T2 has elapsed, control is performed so that power is not supplied even if the plug P1 is newly inserted into the power plug insertion port 29a. Moreover, even if the plug P2 with the ground electrode is inserted into the power plug insertion port 29b, control is performed so that power is not supplied.
(5) When the plug set allowable time T2 has elapsed, if neither the plug P1 nor the plug P2 with the ground electrode is inserted, the coil 35a of the electromagnetic relay 35 and the coil 37a of the electromagnetic relay 37 are de-energized, and thereafter The power supply to the plug receiver 29c can be stopped.

  According to the above configuration, even if the RFID tag 73 is placed outside the communication range after the identification information of the RFID tag 73 has been read and authenticated within the communication range, the anti-theft means will detect the blade detection sensors 63 and 65. Based on the detection results of the blades of the plug P1 and the plug P2 with the ground electrode, the electromagnetic relays 35 and 37 can be individually controlled to prevent theft. That is, the RFID tag 73 functions as a temporary electronic key, and it is not necessary to always read the identification information stored in the RFID tag 73 by the identification information reading unit. Therefore, it is possible to eliminate the possibility that the IC card is stolen during charging and the IC card is copied or the identification information is stolen. In addition, since there is no need to attach an RFID to the power plug, the possibility of a person attempting to steal power to remove the power plug or remove the RFID tag and place the RFID tag in the proximity of the RFID read / write device to eliminate the power it can.

  As a result, it is possible to provide an outlet device with a high anti-theft effect.

(Second Embodiment)
In the first embodiment, the RFID read / write device 75 and the anti-theft control device 39 are connected by wire, but the RFID read / write device 75 and the anti-theft control device 39 are connected. It may be connected wirelessly. In the following description, the start button 77a, the setting completion button 77b, the stop button 77c, and the power supply lamp 77d described in FIG. 8 are collectively referred to as a button / lamp group 77A.

  As shown in FIG. 12, the input device 17 includes an RFID read / write device 75 and an operation unit 77A, and also includes a microprocessor 79, a transmission module 81, and a reception module 83. On the other hand, a reception module 85 and a transmission module 87 are provided on the anti-theft control device 39 side.

  The transmission module 81 described above has a modulation / transmission function, and the reception module 83 has a reception / demodulation function, and wireless communication is performed between them.

When the mobile phone T incorporating the RFID tag 73 is brought close to the RFID read / write device 75, the RFID read / write device 75 reads the identification information of the RFID tag 73 and performs authentication. The recognition result of the identification information is transmitted in the order of the microprocessor 79, the transmission module 81, and the reception module 83, and is output to the anti-theft control device 39. The recognition result of the identification information may be directly transmitted to the transmission module 81. In addition, a signal for turning on and off the power supply lamp 77 d is transmitted from the anti-theft power control device 39 to the microprocessor 79 via the transmission module 87 and the reception module 83.

(Third embodiment)
In the first embodiment and the second embodiment, the electromagnetic relays are individually controlled based on the plug insertion state, but a plug receiver that supplies power or a plug receiver that does not supply power may be manually selected. FIG. 13 is an apparatus configuration diagram according to the third embodiment, and FIG. 14 is an external view of an input device according to the third embodiment.

  As shown in FIG. 14, the RFID read / write device 75 is provided with selection buttons 77e and 77f. Each time the selection button 77e is pressed, an energization signal and a cutoff signal are alternately output via the interface. At this time, the flag L = 1 is stored in the memory 51 shown in FIG. 13 when the energization signal is output, and the flag L = 0 is stored when the cutoff signal is output. Further, every time the selection button 77f is pressed, an energization signal and a cutoff signal are alternately output via the interface. At this time, the flag R = 1 is stored in the memory 51 when the energization signal is output, and the flag R = 0 is stored in the memory 51 when the cutoff signal is output. The CPU 49 outputs a command signal for turning on or off the selection lamps 77g and 77h based on the values of the flag L and the flag R. The selection buttons 77e and 77f described above are valid until the plug set allowable time T2 ends after the identification information is authenticated. When the plug set allowable time T2 ends, based on the values of the flag L and the flag R, control is performed so that power is not supplied to the plug receiver that is not supplied with power. Detailed control procedures are omitted.

(Fourth embodiment)
In the first to third embodiments, the case where the outlet device is provided with a plurality of plug receptacles has been described. However, the outlet device may be provided with one plug receptacle. FIG. 15 shows an apparatus configuration diagram. Note that the mounting configuration of the outlet 13, the anti-theft device 15, and the input device 17 is configured in the same manner as in the first embodiment.

  Next, the control procedure of the fourth embodiment will be described. FIG. 16 and FIG. 17 show an example of the control procedure of the outlet device 11 in the fourth embodiment.

  The control from step S10 to step S100 is the same control as step S10 to step S130 of the control procedure described in the first embodiment. As in the first embodiment, the time when the plug set allowable time T2 ends is set as a control reference point. However, when the identification information input allowable time T1 has elapsed in step S30, if the identification information is not authenticated in step S50, the process proceeds to step S140.

  In step S110, it is determined whether or not the allowable power supply time T3 has elapsed. If the power supply allowable time T3 has elapsed, the process proceeds to step S140. If the power supply allowable time T3 has not elapsed, the process proceeds to step S120.

  In step S120, the power supply lamp 77d is lit red. After the processing, the process proceeds to step S130.

  In step S130, it is detected whether or not the plug P1 is inserted. If the blade detection sensor 63 cannot detect the blade of the plug P1, the process proceeds to step S140. If the blade of the plug P1 is detected, the process proceeds to step S110.

  In step S140, the electromagnetic relay 35 is turned off. The CPU 49 outputs a command signal for making the coil 35 a in a non-excited state, and puts the coil 35 a in a non-excited state via the power supply separation circuit 53 and the driver 57. Before step S130, if the coil 35a is in a non-excited state, the non-excited state of the coil 35a is maintained. Since the mechanical contact 35b is kept open, power is not supplied to the plug receiver 29c. Before the execution of step S130, when the coil 35a is in the excited state, the coil 35a is controlled from the excited state to the non-excited state. At that time, the mechanical contact 35b is opened and the power supply to the plug receiver 29c is stopped. After processing, the process proceeds to step S150.

  In step S150, the control ends.

According to the above control procedure, theft can be prevented as follows.
(1) If the identification information is not authenticated, power is not supplied to the plug receiver 29c.
(2) When the control reference point is reached and the blade detection sensor 63 detects the blade of the plug P1, the anti-theft control means energizes the coil 35a of the electromagnetic relay 35 and supplies power to the plug receiver 29c. Can be controlled. If the blade detection sensor 63 cannot detect the blade of the plug P1, the anti-theft control means can control the coil 35a of the electromagnetic relay 35 to be in a non-excited state so as not to supply power to the plug receiver 29c.
(3) When the plug set allowable time T2 elapses, the coil 35a is maintained in an excited state or a non-excited state. When the blade detection sensor 63 detects the blade of the plug P1 and cannot detect the blade of the plug P1, the coil 35a of the electromagnetic relay 35 is brought into a non-excited state assuming that the plug P1 has been removed. The power supply to the plug receiver 29c can be stopped.
(4) After the plug set allowable time T2 has elapsed, control is performed so that power is not supplied even if the plug P1 is newly inserted into the power plug insertion port 29a.
(5) When the plug set allowable time T2 has elapsed, if the plug P1 is not inserted, the coil 35a of the electromagnetic relay 35 can be brought into a non-excited state, and thereafter power supply to the plug receiver 29c can be stopped.

  According to the above configuration, even if the RFID tag 73 is placed outside the communication range after the identification information of the RFID tag 73 is read and authenticated within the communication range, the anti-theft means is plugged by the blade detection sensor 63. Based on the detection result of the blade of P1, the electromagnetic relay 35 can be controlled to prevent theft. That is, the RFID tag 73 functions as a temporary electronic key, and it is not necessary to always read the identification information stored in the RFID tag 73 by the identification information reading unit. Therefore, it is possible to eliminate the possibility that the IC card is stolen during charging and the IC card is copied or the identification information is stolen. In addition, since there is no need to attach an RFID to the power plug, the possibility of a person attempting to steal power to remove the power plug or remove the RFID tag and place the RFID tag in the proximity of the RFID read / write device to eliminate the power it can.

  As a result, it is possible to provide an outlet device with a high anti-theft effect.

(Fifth embodiment)

As explained earlier, the control reference point is a reference point for performing anti-theft control that does not supply power even when a power plug is newly inserted after the control reference point. , Can be set freely.

  For example, in the flowchart of FIG. 10 described in the first embodiment, step S70 may be deleted, and when the power supply lamp 77d is lit in green in step S60, the control reference point may be used. In this case, the configuration of the outlet device may be the same as the structure described in the first embodiment, but performs an authentication operation (an action of bringing the mobile phone T on which the RFID tag 73 is arranged close to the RFID read / write device 75). It is necessary to insert the plug into the plug insertion port before.

(Sixth embodiment)
In the first to fifth embodiments, the case where the outlet device of the present invention is used for outdoor use has been described, but it may be used for indoor use.

The attachment / detachment detection sensor 93 constitutes a covering member detection sensor of the present invention. As the attachment / detachment detection sensor 93, a reflective photoelectric sensor is used, and constitutes an example of the covering member detection sensor of the present invention. The covering member detection sensor is not limited to the reflective photoelectric sensor. For example, a transmissive photoelectric sensor, a limit switch, a capacitive sensor, or the like may be used.

(Eighth embodiment)
In the first to seventh embodiments, the blade of the power plug is detected, but the bottom surface of the power plug may be detected. As shown in FIG. 18, a bottom surface detection sensor 95 that detects the bottom surface of the plug P1 and a bottom surface detection sensor 97 that detects the bottom surface of the plug P2 with a ground electrode are provided in the outlet main body 89.

For example, a proximity sensor or a reflective laser sensor may be used. In the outlet 13, when the seating surface of the plug P1 and the plug P2 with grounding electrode is defined as a boundary surface, the plug side is defined as the plug area, and the outlet side is defined as the outlet area, the above-described bottom detection sensor 95, bottom detection sensor 97 may be placed in the outlet area.

(Ninth embodiment)
As illustrated in FIGS. 19 to 21, the outlet may be formed such that the seating surface (bottom surface) of the power plug is the bottom of the groove 99. In this case, the groove 99 functions as a power failure failure. For example, when the detectable distance of the bottom surface detection sensor 95 is a dimension L1 (distance from the bottom of the groove 99, not shown) and the height of the groove 99 is a dimension L2, the groove 99 is L2> L1. If the height is formed, a person who intends to steal power inserts a predetermined member into the gap between the seating surface (bottom surface) of the power plug and the outlet, and maintains the detection state of the bottom surface detection sensor 95, and the power plug P This is because it becomes difficult to replace and steal power.

  The RFID read / write device 75 has a predetermined communication range (operation space) with respect to the RFID tag 73, and the RFID tag 73 disposed on the mobile phone T is brought close to the communication range, A device that reads and writes information (for example, identification information), and includes a microcomputer that controls an interface with the anti-theft control device 39, a control unit 75a that includes a dedicated IC that communicates with an RFID tag, and an antenna 75b. ing. The RFID read / write device 75 constitutes identification information reading means of the present invention. In the first embodiment, only one RFID read / write device 75 is used for the plurality of plug receivers 29c and 29d. After the identification information of the RFID tag 73 is read and authenticated within the communication range, the RFID tag 73 is placed outside the communication range.

The RFID read / write device 75 and the RFID tag 73 are well-known technologies, and the identification information reading procedure is omitted. The reading of the identification information may be so-called mutual authentication from the viewpoint of security. The RFID tag 73 may function regardless of whether the cellular phone T is turned on. The RFID tag 73 sets a password by pressing a numeric key of the mobile phone T while the screen of the mobile phone T is displayed, and the entered password matches a predetermined password stored in the mobile phone T in advance. Only it may function.

  As shown in FIG. 8, the operation unit 77 includes a start button 77a, a setting completion button 77b, a stop button 77c, and a power supply lamp 77d. The start button 77a is a button for turning on power to the anti-theft control device 39 and starting control. The setting completion button 77b is used when the plug set of the plug P1 and the grounding electrode plug P2 (the action of selecting the power plug to be inserted and inserting the power plug) is completed within the plug set allowable time T2 described later. This button is pressed when it is desired to start an anti-theft control described later without waiting for the time T2. The stop button 77c is a button to be pressed in an emergency or when it is desired to stop using the outlet. The power supply lamp 77d is a lamp that informs the operator of the control state by color. The concept of the plug set (the action of selecting the power plug to be inserted and inserting the power plug) includes the case where the power plug is not inserted into any of the plug receptacles.

Next, the identification information input allowable time T1, the plug set allowable time T2, and the power supply allowable time T3 will be described.

  The identification information input allowable time T1 is an allowable time for the RFID read / write device 75 to read identification information. The plug set allowable time T2 is an allowable time until the anti-theft control is performed. The power supply allowable time T3 is an allowable time for power supply.

  Next, the control procedure of the first embodiment will be described. FIG. 9 to FIG. 11 show an example of the control procedure of the outlet device 11 in the first embodiment.

  In step S10, the start button 77a of the operation unit 77 is pressed. The power supply lamp 17d is lit red.

  In step S20, identification information input allowable time T1, plug set allowable time T2, and power supply allowable time T3 are initialized. The timer circuit 61 starts timing.

  In step S30, it is determined whether or not the identification information input allowable time T1 has elapsed. If the identification information input allowable time T1 has elapsed, the process proceeds to step S210. If the identification information input allowable time T1 has not elapsed, the process proceeds to step S40.

  In step S40, the mobile phone T in which the RFID tag 73 is built is placed within the communication range (operation range) of the RFID read / write device 75, and an authentication operation is performed. After the operation, the process proceeds to step S50.

  In step S50, whether or not the identification information is authenticated is determined. If the identification information is authenticated, the process proceeds to step S60. If the identification information is not authenticated, the process proceeds to step S210.

  In step S60, the power supply lamp 17d is lit in green. It progresses to step S70 after control. When the identification information is authenticated and the power supply lamp 17d is lit in green, the mobile phone T on which the FID tag 73 is placed is placed outside the communication range (operation range) of the RFID read / write device 75.

  In step S70, it is determined whether the plug set allowable time T2 has elapsed. If it is within the plug set allowable time T2, the process proceeds to step S70. When the plug set allowable time T2 has elapsed, the process proceeds to step S80. Within the plug set allowable time T2, the plug P1 that requires power supply and the plug P2 with a ground electrode are inserted into the plug receivers 29c and 29d. Even if the plug set allowable time T2 has not elapsed after step S60, when the plug set is completed and the setting completion button 77b of the operation unit 77 is pressed, an interrupt process is immediately performed, and step 80 is performed. Proceed to

  In step S80, it is detected whether or not the plug P1 is inserted into the plug receiver 29c. If the blade detection sensor 63 detects the blade of the plug P1, the process proceeds to step S90. If the blade detection sensor 63 cannot detect the blade of the plug P1, the process proceeds to step S100.

  In step S90, the electromagnetic relay 35 is turned on. The CPU 49 outputs a command signal for exciting the coil 35 a of the electromagnetic relay 35, and excites the coil 35 a via the power supply separation circuit 53 and the driver 57. Usually, before execution of step S80, the coil 35a is in a non-excited state, and the coil 35a is controlled from a non-excited state to an excited state. At that time, the mechanical contact 35b is closed and power is supplied to the plug receiver 29c. After processing, the process proceeds to step S110.

  In step S100, the electromagnetic relay 35 is turned off. The CPU 49 outputs a command signal for bringing the coil 35 a of the electromagnetic relay 35 into a non-excited state, and puts the coil 35 a into a non-excited state via the power supply separation circuit 53 and the driver 57. Usually, before the execution of step S80, the coil 35a is in a non-excited state, so that the non-excited state of the coil 35a is maintained. Since the mechanical contact 35b is kept open, power is not supplied to the plug receiver 29c. After processing, the process proceeds to step S110.

  In step S110, it is detected whether or not the grounded electrode plug P2 is inserted into the plug receiver 29d. If the blade detection sensor 65 detects the blade of the plug P1, the process proceeds to step S120. If the blade detection sensor 65 cannot detect the blade of the plug P2 with the ground electrode, the process proceeds to step S130.

  In step S120, the electromagnetic relay 37 is turned on. The CPU 49 outputs a command signal for exciting the coil 37 a of the electromagnetic relay 37 and excites the coil 37 a via the power supply separation circuit 55 and the driver 59. Usually, before execution of step S110, the coil 37a is in a non-excited state, and the coil 37a is controlled from a non-excited state to an excited state. At that time, the mechanical contact 37b is closed and power is supplied to the plug receiver 29d. After processing, the process proceeds to step S140.

  In step S130, the electromagnetic relay 37 is turned off. The CPU 49 outputs a command signal for deactivating the coil 37a of the electromagnetic relay 37, and deenergizes the coil 37a via the power supply separation circuit 55 and the driver 59. Usually, before the execution of step S110, the coil 37a is in a non-excited state, so that the non-excited state of the coil 37a is maintained. Since the mechanical contact 37b is kept open, no power is supplied to the plug receiver 29d. After processing, the process proceeds to step S140.

  In step S140, it is determined whether or not the allowable power supply time T3 has elapsed. When the power supply allowable time T3 has elapsed, the process proceeds to step S210. If the power supply allowable time T3 has not elapsed, the process proceeds to step S150.

  In step S150, the power supply lamp 17d is lit red. After processing, the process proceeds to step S160.

  In step S160, it is detected whether or not the plug P1 and the ground electrode plug P2 are inserted. If neither the blade of the plug P1 nor the blade of the ground electrode plug P2 is detected, the process proceeds to step S210. When any one or more of the blade of the plug P1 and the blade of the plug P2 with the ground electrode is detected, the process proceeds to step S170.

  In step S170, it is detected whether or not the plug P1 is inserted. If the plug P1 is not detected, the process proceeds to step S180. If the plug P1 is detected, the process proceeds to step S190.

  In step S180, the electromagnetic relay 35 is turned off. The CPU 49 outputs a command signal for making the coil 35 a in a non-excited state, and puts the coil 35 a in a non-excited state via the power supply separation circuit 53 and the driver 57. If the coil 35a is in a non-excited state before execution of step S170, the non-excited state of the coil 35a is maintained. Since the mechanical contact 35b is kept open, power is not supplied to the plug receiver 29c. Before the execution of step S170, when the coil 35a is in the excited state, the coil 35a is controlled from the excited state to the non-excited state. At that time, the mechanical contact 35b is opened and the power supply to the plug receiver 29c is stopped. After processing, the process proceeds to step S190. Thereafter, power supply to the plug receptacle 29c is stopped until the control is completed.

  In step S190, it is detected whether or not the grounding electrode plug P2 is inserted. If the blade of the ground electrode plug P2 is not detected, the process proceeds to step S200. When the blade of the ground electrode plug P2 is detected, the process proceeds to step S140.

  In step S200, the electromagnetic relay 37 is turned off. The CPU 49 outputs a command signal for making the coil 37 a in a non-excited state, and puts the coil 37 a in a non-excited state via the power supply separation circuit 55 and the driver 59. If the coil 37a is in a non-excited state before execution of step S190, the non-excited state of the coil 37a is maintained. Since the mechanical contact 37b is kept open, no power is supplied to the plug receiver 29d. If the coil 37a is in an excited state before the execution of step S190, the coil 37a is controlled from the excited state to the non-excited state. At that time, the mechanical contact 37b is opened and the power supply to the plug receiver 29d is stopped. After processing, the process proceeds to step S140. Thereafter, power supply to the plug receiver 29d is stopped until the control is completed.

  In step S210, the electromagnetic relay 35 and the electromagnetic relay 37 are turned off. Further, the power supply lamp 77d is turned off. The CPU 49 outputs a command signal for bringing the coil 35 a into a non-excited state, and puts the coil 35 a of the electromagnetic relay 35 into a non-excited state via the power supply separation circuit 53 and the driver 57. Similarly, the CPU 49 outputs a command signal for setting the coil 37a in a non-excited state, and sets the coil 37a of the electromagnetic relay 37 in a non-excited state via the power supply separation circuit 55 and the driver 59. Normally, when the execution of step S210 is started, the coils 35a and 37a are in the non-excited state, so the non-excited state is maintained. Since the mechanical contacts 35b and 37b are kept open, power is not supplied to the plug receivers 29c and 29d. Note that branch control is performed from step S30, step S50, and step S140, and when step 210 is reached, the electromagnetic relay 35 and the electromagnetic relay 37 are controlled to immediately stop power feeding. After processing, the process proceeds to step S220.

  In step S220, the control ends. When the stop button 77c is pressed, interrupt control is performed, the electromagnetic relay 35 and the electromagnetic relay 37 are controlled, and power supply is immediately stopped.

According to the above control procedure, theft can be prevented as follows.
(1) When the identification information is not authenticated , power is not supplied to the plug receptacles 29c and 29d.
(2) When the control reference point is reached, the identification information is authenticated, and when the plug set allowable time T2 elapses , power is supplied to the plug receivers 29c and 29d according to the insertion status of the plug P1 and the ground electrode plug P2. . Specifically, among the blade detection sensors 63 and 65, when the blade detection sensor 63 detects the blade of the plug P1, and the blade detection sensor 65 cannot detect the blade of the plug P2 with the ground electrode, the anti-theft control means However, the coil 35a of the electromagnetic relay 35 can be brought into an excited state and can be controlled to supply power only to the plug receiver 29c. Of the blade detection sensors 63 and 65, when the blade detection sensor 65 detects the blade of the plug P2 with the grounding electrode and the blade detection sensor 63 cannot detect the blade of the plug P1, the anti-theft control means controls the electromagnetic relay 37. It is possible to control so that the coil 37a is energized and power is supplied only to the plug receptacle 29d. When the blade detection sensors 63 and 65 detect the blade of the plug P1 and the blade of the plug P2 with the ground electrode, respectively, the anti-theft control means puts the coil 35a of the electromagnetic relay 35 and the coil 37a of the electromagnetic relay 37 into an excited state. Thus, it is possible to control to supply power to both the plug receivers 29c and 29d. When the blade detection sensors 63 and 65 cannot detect the blade of the plug P1 and the blade of the plug P2 with the ground electrode, respectively, the anti-theft control means de-energizes the coil 35a of the electromagnetic relay 35 and the coil 37a of the electromagnetic relay 37. Thus, it is possible to control not to supply power to both plug receptacles 29c and 29d.
(3) When the plug set allowable time T2 elapses, the excitation state or the non-excitation state of the coil 35a and the coil 37a is maintained. When the blade detection sensor 63 detects the blade of the plug P1 and cannot detect the blade of the plug P1, the coil 35a of the electromagnetic relay 35 is brought into a non-excited state assuming that the plug P1 has been removed. The power supply to the plug receiver 29c can be stopped. Further, when the blade detection sensor 65 detects the blade of the plug P2 with the ground electrode and becomes unable to detect the blade of the plug P2 with the ground electrode, it is assumed that the plug P2 with the ground electrode is removed and the electromagnetic relay The coil 37a of 37 can be de-energized, and thereafter the power supply to the plug receiver 29d can be stopped.
(4) After the plug set allowable time T2 has elapsed, control is performed so that power is not supplied even if the plug P1 is newly inserted into the power plug insertion port 29a. Moreover, even if the plug P2 with the ground electrode is inserted into the power plug insertion port 29b, control is performed so that power is not supplied.
(5) When the plug set allowable time T2 has elapsed, if neither the plug P1 nor the plug P2 with the ground electrode is inserted, the coil 35a of the electromagnetic relay 35 and the coil 37a of the electromagnetic relay 37 are de-energized, and thereafter The power supply to the plug receiver 29c can be stopped.

According to the above configuration, even if the RFID tag 73 is placed outside the communication range after the identification information of the RFID tag 73 has been read and authenticated within the communication range, the anti-theft means will detect the blade detection sensors 63 and 65. Based on the detection results of the blades of the plug P1 and the plug P2 with the ground electrode, the electromagnetic relays 35 and 37 can be individually controlled to prevent theft. That is, the RFID tag 73 functions as a temporary electronic key, and it is not necessary to always read the identification information stored in the RFID tag 73 by the identification information reading unit. Therefore, the problem described in Patent Document 1, that is, the possibility that a person who intends to steal power removes the power plug or removes the RFID tag and closes the RFID tag to the RFID read / write device to steal can be eliminated. This outlet device is equipped with all necessary means (blade bottom detecting means, electric circuit switch, RFID tag, identification information reading means, identification information authentication means, anti-theft control means) to prevent theft. Even a power consumer that does not have a special means for preventing theft can be prevented from being stolen.

  As a result, it is possible to provide an outlet device with a high anti-theft effect.

On the other hand, a reception module 85 and a transmission module 87 are provided on the anti-theft control device 39 side.

  The transmission module 81 described above has a modulation / transmission function, and the reception module 83 has a reception / demodulation function, and wireless communication is performed between them. Further, the transmission module 87 has a modulation / transmission function, and the reception module 85 has a reception / demodulation function, and wireless communication is performed between them. When the mobile phone T incorporating the RFID tag 73 is brought close to the RFID read / write device 75, the RFID read / write device 75 reads the identification information of the RFID tag 73 and performs authentication. The recognition result of the identification information is transmitted in the order of the microprocessor 79, the transmission module 81, and the reception module 83, and is output to the anti-theft control device 39. The recognition result of the identification information may be directly transmitted to the transmission module 81. In addition, a signal for turning on and off the power supply lamp 77 d is transmitted from the anti-theft power control device 39 to the microprocessor 79 via the transmission module 87 and the reception module 83.

(Third embodiment)
In the first embodiment and the second embodiment, the electromagnetic relays are individually controlled based on the plug insertion state, but a plug receiver that supplies power or a plug receiver that does not supply power may be manually selected. FIG. 13 is an apparatus configuration diagram according to the third embodiment, and FIG. 14 is an external view of an input device according to the third embodiment.

  As shown in FIG. 14, the RFID read / write device 75 is provided with selection buttons 77e and 77f. Each time the selection button 77e is pressed, an energization signal and a cutoff signal are alternately output via the interface. At this time, the flag L = 1 is stored in the memory 51 shown in FIG. 13 when the energization signal is output, and the flag L = 0 is stored when the cutoff signal is output. Further, every time the selection button 77f is pressed, an energization signal and a cutoff signal are alternately output via the interface. At this time, the flag R = 1 is stored in the memory 51 when the energization signal is output, and the flag R = 0 is stored in the memory 51 when the cutoff signal is output. The CPU 49 outputs a command signal for turning on or off the selection lamps 77g and 77h based on the values of the flag L and the flag R. The selection buttons 77e and 77f described above are valid until the plug set allowable time T2 ends after the identification information is authenticated. When the plug set allowable time T2 ends, based on the values of the flag L and the flag R, control is performed so that power is not supplied to the plug receiver that is not supplied with power. Detailed control procedures are omitted.

(Fourth embodiment)
In the first to third embodiments, the case where the outlet device is provided with a plurality of plug receptacles has been described. However, the outlet device may be provided with one plug receptacle. FIG. 15 shows an apparatus configuration diagram. Note that the mounting configuration of the outlet 13, the anti-theft device 15, and the input device 17 is configured in the same manner as in the first embodiment.

  Next, the control procedure of the fourth embodiment will be described. FIG. 16 and FIG. 17 show an example of the control procedure of the outlet device 11 in the fourth embodiment.

The control from step S10 to step S100 is the same as the control from step S10 to step S130 in the control procedure described in the first embodiment . However, when the identification information input allowable time T1 has elapsed in step S30, if the identification information is not authenticated in step S50, the process proceeds to step S140.

  In step S110, it is determined whether or not the allowable power supply time T3 has elapsed. If the power supply allowable time T3 has elapsed, the process proceeds to step S140. If the power supply allowable time T3 has not elapsed, the process proceeds to step S120.

  In step S120, the power supply lamp 77d is lit red. After the processing, the process proceeds to step S130.

  In step S130, it is detected whether or not the plug P1 is inserted. If the blade detection sensor 63 cannot detect the blade of the plug P1, the process proceeds to step S140. If the blade of the plug P1 is detected, the process proceeds to step S110.

  In step S140, the electromagnetic relay 35 is turned off. The CPU 49 outputs a command signal for making the coil 35 a in a non-excited state, and puts the coil 35 a in a non-excited state via the power supply separation circuit 53 and the driver 57. Before step S130, if the coil 35a is in a non-excited state, the non-excited state of the coil 35a is maintained. Since the mechanical contact 35b is kept open, power is not supplied to the plug receiver 29c. Before the execution of step S130, when the coil 35a is in the excited state, the coil 35a is controlled from the excited state to the non-excited state. At that time, the mechanical contact 35b is opened and the power supply to the plug receiver 29c is stopped. After processing, the process proceeds to step S150.

  In step S150, the control ends.

According to the above control procedure, theft can be prevented as follows.
(1) When the identification information is not authenticated , power is not supplied to the plug receiver 29c.
(2) When the identification information is authenticated, the plug set allowable time T2 has elapsed, and the blade detection sensor 63 detects the blade of the plug P1, the anti-theft control means puts the coil 35a of the electromagnetic relay 35 in an excited state. Thus, the plug receiver 29c can be controlled to supply power. If the blade detection sensor 63 cannot detect the blade of the plug P1, the anti-theft control means can control the coil 35a of the electromagnetic relay 35 to be in a non-excited state so as not to supply power to the plug receiver 29c.
(3) When the plug set allowable time T2 elapses, the coil 35a is maintained in an excited state or a non-excited state. When the blade detection sensor 63 detects the blade of the plug P1 and cannot detect the blade of the plug P1, the coil 35a of the electromagnetic relay 35 is brought into a non-excited state assuming that the plug P1 has been removed. The power supply to the plug receiver 29c can be stopped.
(4) After the plug set allowable time T2 has elapsed, control is performed so that power is not supplied even if the plug P1 is newly inserted into the power plug insertion port 29a.
(5) When the plug set allowable time T2 has elapsed, if the plug P1 is not inserted, the coil 35a of the electromagnetic relay 35 can be brought into a non-excited state, and thereafter power supply to the plug receiver 29c can be stopped.

According to the above configuration, even if the RFID tag 73 is placed outside the communication range after the identification information of the RFID tag 73 is read and authenticated within the communication range, the anti-theft means is plugged by the blade detection sensor 63. Based on the detection result of the blade of P1, the electromagnetic relay 35 can be controlled to prevent theft. That is, the RFID tag 73 functions as a temporary electronic key, and it is not necessary to always read the identification information stored in the RFID tag 73 by the identification information reading unit. Therefore, the problem described in Patent Document 1, that is, the possibility that a person who intends to steal power removes the power plug or removes the RFID tag and closes the RFID tag to the RFID read / write device to steal can be eliminated. This outlet device is equipped with all necessary means (blade bottom detecting means, electric circuit switch, RFID tag, identification information reading means, identification information authentication means, anti-theft control means) to prevent theft. Even a power consumer that does not have a special means for preventing theft can be prevented from being stolen.

  As a result, it is possible to provide an outlet device with a high anti-theft effect.

(Fifth embodiment)
In the first embodiment and the fourth embodiment, the power supply is stopped when the inserted power plug is removed after the plug set allowable time T2 has elapsed. However, the present invention is not limited to this.

For example, step S70 may be deleted in the flowchart of FIG. 10 described in the first embodiment . In this case, the configuration of the outlet device may be the same as the structure described in the first embodiment, but performs an authentication operation (an action of bringing the mobile phone T on which the RFID tag 73 is arranged close to the RFID read / write device 75). It is necessary to insert the plug into the plug insertion port before.

(Sixth embodiment)
In the first to fifth embodiments, the case where the outlet device of the present invention is used for outdoor use has been described, but it may be used for indoor use. FIG. 18 shows a side view when the outlet device of the present invention is used indoors. In this case, it is preferable to provide a cover, a lock or the like on the anti-theft device 15 so that the setting change means 67 cannot be operated, and to prevent the theft easily from the anti-theft device 15.

(Seventh embodiment)
In the first to sixth embodiments, there is a risk that the cover 27 is removed and electric power is stolen from the internal wiring. Therefore, as shown in FIG. 18, an attachment / detachment detection sensor 93 for detecting attachment / detachment of the cover 91 is provided in the outlet body 89, and when the cover 91 is removed, power supply to the plug receptacles 29c, 29d is stopped. May be. The cover 91 constitutes an example of a covering member of the present invention. The attachment / detachment detection sensor 93 constitutes a covering member detection sensor of the present invention. As the attachment / detachment detection sensor 93, a reflective photoelectric sensor is used, and constitutes an example of the covering member detection sensor of the present invention. The covering member detection sensor is not limited to the reflective photoelectric sensor. For example, a transmissive photoelectric sensor, a limit switch, a capacitive sensor, or the like may be used.

(Eighth embodiment)
In the first to seventh embodiments, the blade of the power plug is detected, but the bottom surface of the power plug may be detected. As shown in FIG. 18, a bottom surface detection sensor 95 that detects the bottom surface of the plug P1 and a bottom surface detection sensor 97 that detects the bottom surface of the plug P2 with a ground electrode are provided in the outlet main body 89. The bottom surface detection sensor 95 and the bottom surface detection sensor 97 correspond to the blade detection sensor shown in the first embodiment, and constitute the bottom surface detection means of the present invention.

  The bottom surface detection sensor 95 and the bottom surface detection sensor 97 are reflective photoelectric sensors, but are not limited thereto. For example, a proximity sensor or a reflective laser sensor may be used. In the outlet 13, when the seating surface of the plug P1 and the plug P2 with grounding electrode is defined as a boundary surface, the plug side is defined as the plug area, and the outlet side is defined as the outlet area, the above-described bottom detection sensor 95, bottom detection sensor 97 may be placed in the outlet area.

(Ninth embodiment)
As illustrated in FIGS. 19 to 21, the outlet may be formed such that the seating surface (bottom surface) of the power plug is the bottom of the groove 99. In this case, the groove 99 functions as a power failure failure. For example, when the detectable distance of the bottom surface detection sensor 95 is a dimension L1 (distance from the bottom of the groove 99, not shown) and the height of the groove 99 is a dimension L2, the groove 99 is L2> L1. If the height is formed, a person who intends to steal power inserts a predetermined member into the gap between the seating surface (bottom surface) of the power plug and the outlet, and maintains the detection state of the bottom surface detection sensor 95, and the power plug P This is because it becomes difficult to replace and steal power. The gap t1 between the plug P1 and the groove side surface 99a is preferably small.

  The timing at which the blade detection sensors 63 and 65 (see FIG. 7) described in the first to third embodiments detect the blade of the plug P1 and the blade of the plug P2 is before the identification information is authenticated. It may be. In this case, the plug set is completed within the plug set allowable time T2, and after the setting completion button 77b is pressed, the RFID tag 73 is brought close to the RFID read / write device 75 within a short period of time (for example, within 10 seconds) to obtain the identification information. If authentication is not performed, it may be controlled not to supply power to the power plug receptacles 29c and 29d.

  Similarly, the timing at which the blade detection sensor 63 (see FIG. 15) described in the fourth embodiment detects the blade of the plug P1 may be before the identification information is authenticated. In this case, the plug set is completed within the plug set allowable time T2, the setting completion button 77b is pressed, and then the RFID tag 73 is brought close to the RFID read / write device 75 for a short time (for example, within 10 seconds) for identification. If the information is not authenticated, it may be controlled not to supply power to the power supply plug receptacle 29c.

Further , as in the first embodiment, after the identification information is authenticated , the electromagnetic relays 35 and 37 are not controlled for the first time, but before the identification information is authenticated, the blade of the plug P1 and the grounding plug When the blade of P2 is detected, the plug receptacle that has detected the blade of plug P1 and the blade of plug P2 with ground electrode is energized, and when the identification information is authenticated, the blade of plug P1 and plug of ground electrode P2 You may stop the electric power feeding to the plug receptacles 29c and 29d which cannot detect a blade. In this case, the plug set is completed within the plug set allowable time T2, the setting completion button 77b is pressed, and then the RFID tag 73 is brought close to the RFID read / write device 75 for a short time (for example, within 10 seconds) for identification. If the information is not authenticated, it may be controlled not to supply power to the power plug receptacles 29c and 29d.
