The block diagram which shows roughly the structure of an automatic ticket vending machine as an example of the station service apparatus which concerns on embodiment. The flowchart explaining operation | movement of the automatic ticket vending machine which concerns on embodiment.

Hereinafter, station equipment according to an embodiment will be described with reference to the drawings.
FIG. 1 schematically shows the configuration of an automatic ticket vending machine as an example of a station service device according to the present embodiment. The automatic ticket vending machine 10 according to the present embodiment is roughly divided into a ticket vending machine unit 20 and a battery power supply unit 30. The ticket vending machine unit 20 accepts a fee based on a user's operation and issues a mechanical unit 21 such as a ticketing unit that issues a desired boarding ticket, a control unit 22 that controls the mechanical unit 21, and an AC ( AC power supply unit (AC voltage) and a direct current (DC) operation power source (DC voltage) are supplied to the control unit 22.

  The power supply unit 23 rectifies and stabilizes the AC voltage (for example, AC 100 volts) supplied from the battery power supply unit 30 to generate an operation power supply of a predetermined DC voltage and supplies it to the control unit 22. Then, based on the AC voltage supplied from the battery power supply unit 30, an operation power supply having a predetermined AC voltage is generated and supplied to the mechanical unit 21.

  The battery power supply unit 30 is connected to a commercial AC power supply 50 and operates with an accumulator 31 that is detachably installed and an AC voltage (for example, AC 100 volts) supplied from the commercial AC power supply 50 to charge the storage battery 31. A charging circuit 32 mainly composed of a converter that connects to the charging circuit 32 and the commercial AC power supply 50, a switch 33 that turns on and off the supply of the commercial AC power supply 50 to the charging circuit 32, and an output voltage of the storage battery 31 Is converted to a predetermined AC voltage (for example, AC 100 volts) and supplied to the power supply unit 23 as an operating power supply, and when the output voltage of the storage battery 31 is equal to or lower than a predetermined value set in advance, a voltage detection unit 35 that detects that , A timer 36 for setting a time zone for turning off the switch 33, a detection result of the voltage detector 35, and a setting of the timer It turns on the switch 33 based on the contents, and a switch control unit 37 to turn off control.

  The timer 36 sets a time zone when the switch 33 is turned off, and sets an off time zone such as “12 o'clock to 15 o'clock” or “8 o'clock to 17 o'clock” at the peak of the daytime power demand. .

  For example, the switch control unit 37 sets the switch 33 to an off state when the current time is an off time set by the timer 36, and sets the switch 33 to an on state otherwise. Further, when the switch control unit 37 detects that the output voltage of the storage battery 31 has become equal to or lower than the specified value when the switch 33 is in the off state, the switch control unit 37 transmits the detection signal to the control unit 22. By displaying on the attendant panel of the control unit 22, the attendant is notified that the output voltage of the storage battery 31 has become equal to or lower than the specified value, and the switch 33 is set to the ON state.

  The storage battery 31 may be fixedly installed in the battery power supply unit 30 or may be installed detachably. When the storage battery 31 is detachable, for example, the storage battery 31 used by the installer of the automatic ticket vending machine 10 can be selected and installed later.

  The voltage detection unit 35 may be provided outside the storage battery 31 or may be provided inside the storage battery 31. Further, the timer 36 may be integrated with the switch control unit 37 or may be integrated with the control unit 22. Further, the control unit 22 may have functions of the timer 36 and the switch control unit 37.

  Next, the operation of the automatic ticket vending machine 10 according to this embodiment will be described with reference to the flowchart shown in FIG. 2 in such a configuration.

  First, the timer 36 sets a time zone for turning off the switch 33 (a time zone for turning off the power supply from the commercial AC power supply 50). For example, when suppressing power during the daytime when power demand peaks, an off time zone is set such as “12:00 to 15:00” or “8 to 17:00”.

  The switch control unit 37 determines whether or not the current time is in the off time zone set by the timer 36 (step S1). If the current time is not in the off time zone, the switch control unit 37 sets the switch 33 to the on state, and the commercial AC power supply 50 is supplied to the charging circuit 32 (step S2).

  The charging circuit 32 operates by the alternating voltage supplied from the commercial alternating current power supply 50, and charges the storage battery 31 (step S3). The inverter 34 converts the output voltage of the storage battery 31 into a predetermined AC voltage (for example, AC 100 volts), and supplies it to the power supply unit 23 as an operating power supply (step S4).

  As described above, when the current time is not the off-time zone, it is possible to supply the operation power to the ticket vending machine unit 20 while charging the storage battery 31 and to operate the ticket vending machine unit 20.

  In step S1, when the current time is in the off time zone, the switch control unit 37 sets the switch 33 to the off state and cuts off the supply of the commercial AC power supply 50 to the charging circuit 32 (step S5). The charging circuit 32 stops charging the storage battery 31 (step S6).

  In this case, even if the charging of the storage battery 31 is stopped, the inverter 34 converts the output voltage of the storage battery 31 into a predetermined AC voltage and supplies it to the power supply unit 23 as an operating power supply.

  As described above, when the current time is in the off-time zone, the supply of the commercial AC power supply 50 is cut (stopped), and the operation power is supplied from the storage battery 31 charged at night or the like to the ticket vending machine unit 20. 20 can be operated.

  Next, the switch control unit 37 determines whether or not the voltage detection unit 35 has detected that the output voltage of the storage battery 31 has become a specified value or less (step S7), and the output voltage of the storage battery 31 has a specified value or less. When it is not detected that the battery has become, the process proceeds to step S4, and the power supply from the storage battery 31 is continued.

In step S7, when it is detected that the output voltage of the storage battery 31 has become equal to or less than the specified value, the switch control unit 37 sends the detection signal to the control unit 22 so that the output voltage of the storage battery 31 is set to the specified value. The fact that it has become below is notified (step S8).
Next, the switch control unit 37 proceeds to step S4 to set the switch 33 to the ON state, and thereafter repeats the same operation as described above.

  Thus, when the switch 33 is in the OFF state, when the voltage detection unit 35 detects that the output voltage of the storage battery 31 has become equal to or less than the specified value, it notifies the attendant and turns the switch 33 on forcibly. In this state, the supply of the commercial AC power supply 50 is resumed.

  According to the automatic ticket vending machine 10 of at least one embodiment described above, since it is operated by using the power charged in the storage battery 31 at night or the like at the daytime power peak, the operation is performed at the daytime power demand peak. A power saving effect equivalent to stopping is obtained. Therefore, it is possible to operate the automatic ticket vending machine 10 that has been stopped for power saving purposes.

  In addition, although the said embodiment demonstrated the case where the storage battery 31 may be installed in the battery power supply part 30 fixedly or may be installed detachably, it is not restricted to this, For example, the storage battery 31 is provided. The same applies to the case where the automatic ticket vending machine 10 is fixedly installed or detachable.

  Moreover, although the said embodiment demonstrated the case where the station service apparatus was the automatic ticket vending machine 10, it is not restricted to this, For example, the case of an automatic ticket gate and a monitoring board is applicable similarly.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
