BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply device for backing up a power supply of various transaction devices such as an automatic cash dispenser and an automatic money changer used in financial business.

[0002]

2. Description of the Related Art Conventionally, various types of transaction processing apparatuses including an automatic cash transaction processing apparatus used in a financial business are designed so that even if a power failure occurs during a transaction, the apparatus does not immediately stop processing operations. There is a means for connecting an uninterruptible power supply so that backup power is supplied from the uninterruptible power supply.

On the other hand, the above-mentioned transaction processing apparatus is, for example,
During operation during business hours, the main power supply unit is controlled to be ON and the power is turned on, so that the main power supply unit is placed in an operation state where trading can be performed at any time, and after the business hours, the main power supply unit is controlled to be OFF and the power is turned off. However, in the next business hours, when there is an operation command from the center or a higher-level device, the main power supply unit is controlled to be ON and put into a standby state in which the main power supply unit is put into an operation state.

In the standby state described above, the transaction processing apparatus is supplied with standby power from a main power supply to a power control circuit for controlling ON / OFF of the main power supply. It is configured to perform ON control.

That is, even if the transaction processing device is placed in a standby state and the power for driving the device is controlled to be OFF, the power supply control circuit portion includes a power supply portion to which standby power is supplied from the main power supply portion. There is.

[0006] In such a standby state of the transaction processing apparatus,
For example, an installation corner in which the transaction processing apparatus is installed or a breaker including the installation corner is usually shut off for a long time for a work such as maintenance and inspection of another apparatus, or the transaction is not performed. When the outlet of the processing device is unexpectedly disconnected and the normal power supply is cut off, the normal power supply of the transaction processing device in the standby state is in a power failure state during the cutoff time. As a result, the backup power supply (starts up) is supplied to the above-described power supply control circuit portion due to the power failure.

However, since the transaction processing device is on standby and the power supply to the power supply control circuit is not required, the supply of the backup power is useless, and even if it is not necessary, the uninterruptible power supply is provided. There is a problem that the capacity of the power supply is output and the life thereof is shortened.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide a power supply device that can eliminate useless backup power supply and prevent a reduction in capacity and life of an uninterruptible power supply.

[0012]

According to the present invention, when the normal power supply whose drive device is controlled to be OFF during standby is blackout, the normal power supply is not restored even if the timer means measures a predetermined time, no operation is performed. Since the supply of the backup power supply of the power failure power supply is stopped by the stopping means, useless supply of the backup power supply can be eliminated, and a reduction in the capacity and life of the uninterruptible power supply can be prevented.

[0013] Further, in a period in which a power failure of the normal power supply is likely to occur, or in summer, when lightning frequently occurs and the power failure occurrence rate of the normal power supply is high, or in a place or area where the power failure frequently occurs, the timer time is set. By coping with the situation, for example, by setting it to be long, reliable backup can be performed against a power failure of the normal power supply during standby, and reliability can be improved.

The main control unit 20 includes a power supply control unit 20a, to which an operation command and a standby command are directly input from a center. When an operation command is input from the center, the power supply device 19 is turned on and the power supply device 19 is driven, and when a standby command is input from the center, the power supply device 19 is controlled to be off.
The power supply 19 is brought into a stop state. The power supply 1
When the power supply 9 is in a stop state, the power supply to each set unit is cut off. However, the power supply control unit 20a and the transmission / reception circuit 28 described later are operated so that an operation command and a standby command are input from the center side. Standby power is supplied from the power supply device 19.

The CRT / touch panel control unit 22 controls the display control and input operation of the CRT 11 which also serves as a touch panel, the attendant panel control unit 23 controls the display control and input operation of the attendant panel 18, and the bill processing unit 24 includes 15, the coin processing unit 25 is connected to the coin entrance 14 to control the coin receiving and dispensing processes, and the card slip processing unit 26 is connected to the coin slot 14. Connected to the insertion slot 13,

The passbook processing unit 27 is connected to the passbook insertion slot 12 and transmits transaction data to the inserted passbook. The recording process is controlled, and the transmission / reception circuit 28 transmits / receives data to / from the center.

The power supply unit 19 comprises a main power supply unit 29 and an uninterruptible power supply unit 30. The main power supply unit 29 has a connector 31 for a commercial power supply, is connected to the commercial power supply, and switches this commercial power supply to a switching circuit. 32, this normal DC power supply is used as a normally used DC power supply (normal DC power supply).
0, and a normally used 100 V power supply (usually 1
This power is supplied to the sub-control units 22 and 23 and the processing units 24 to 27 as a normal power supply, and the power supply control unit 2 of the main control unit 20 is used as a standby power supply.
0a and a DC power supply to the transmission / reception circuit 28. The standby power supply is configured to output even when the power supply 19 is turned off.

An uninterruptible power supply 30 is connected to the main power supply unit 29, and the device 30 charges a commercial power supply supplied from the main power supply unit 29, and is charged when the commercial power supply is cut off. Power is supplied to the main power supply unit 29 as a backup power supply, and the main power supply unit 29 supplies the D signal charged as a backup DC power to the main control unit 20 via the switching circuit 32.
A C power is supplied, and a charged 100 V power is supplied as a backup AC 100 V power to the card slip processing unit 26 and the passbook processing unit 27. Although backup power can be supplied to the other sub-control units 22 and 23 and the respective processing units 24 and 25, power is supplied to the minimum necessary processing units.

FIG. 3 shows the power supply 19 described above. The main power supply 29 has a main breaker 33. When the main breaker 33 is turned on, the commercial power supply is switched to the switching circuit 32 and the uninterruptible power supply 30. The switching circuit 32 normally supplies AC to each of the sub-control units 22 and 23 and each of the processing units 24-27.
It supplies 100V power and also supplies power to a DC power circuit 34. The power circuit 34 normally supplies DC power to the main control unit 20, and further supplies standby power to the power control unit 20a and the transmission / reception circuit. 28.

The control circuit 35 includes the above-described circuit 32,
34, the setting state of the signal setting switch 36, that is, the ON / OFF state and the uninterruptible power supply 30
Is output to the main control unit 20.

Further, the main control unit 2
When a power ON command signal based on the operation command is input from the power control unit 20a, the switching circuit 32 and the power circuit 34 are turned ON to supply power to each unit, and power OFF based on the standby command. When the command signal is inputted, the switching circuit 32 and the power supply circuit 34 are turned off to cut off the power supply to each part, but only the standby power is supplied and utilized.

The above-mentioned signal setting switch 36 determines whether or not the backup is performed by the uninterruptible power supply 30 or not.
0 is a setting switch for notifying O.
When set to N, it indicates that there is a backup of the uninterruptible power supply 30, and when set to OFF, it indicates that there is no backup of the uninterruptible power supply 30.

The uninterruptible power supply 30 has connectors 37 and 3
The battery 41 charges the commercial power supply, the controller 42 controls the charging process and the output cutoff process of the battery 41, and connects to the battery 41. When a failure occurs, the failure signal is output, and the operation switch 43 switches the uninterruptible power supply 30 between an operation state and a non-operation state. Also,
The above-mentioned failures include abnormal charging of the battery 41 (charging error when charging is not performed) and a decrease in capacity.

Further, the control unit 42 stops the output of the battery 41 when the commercial power supply is cut off for a long time while the power supply unit 19 is turned off based on the standby command from the center and is in standby. It has a control function. That is, while the power supply 19 is controlled to be OFF based on the standby command, the uninterruptible power supply 30 outputs the power of the battery 41 when the commercial power supply is interrupted.

In this case, during standby, the power to each unit is cut off from the power supply 19, but standby power is supplied and it is alive. Therefore, due to the above-described power failure of the commercial power supply, the battery 41 outputs power to back up the standby power supply.

By the way, during the above-mentioned standby, for example, when a breaker is turned off due to maintenance work and a power failure occurs for a long time, the power supply control unit 20a of the main control unit 20 does not need to be operated. It is not necessary to make a backup, and if the standby power supply is shut off during this time, it is possible to prevent the capacity and the life of the battery 41 from decreasing.

In order to enable such control, a long-term power failure in which the breaker of the above-described example is cut off and a short-term power failure such as a break in commercial power supply due to a lightning strike (normal power failure) are determined. In the case of a normal power failure, standby power is supplied to take advantage of this. Therefore, the timer circuit 44
And a timer setting unit 45.

The timer circuit 44 measures a set time when the backup power is output from the battery 41 during standby,
The timer setting unit 45 arbitrarily sets the time measured by the timer circuit 44. This time setting is, for example, a time of 30 seconds, 1 minute, or the like. This time setting is selected when a power failure of the normal power supply is likely to occur, or a power failure occurrence rate of the normal power supply due to thunder frequently occurring. In summer, when the weather is high, or in a place or area where the occurrence frequently occurs, the set time is set longer to cope with the situation.

In the power supply device 19 having the above-described configuration, the control unit 42 of the uninterruptible power supply device 30 causes the commercial power supply to be shut down for a long time while the power supply device 19 is turned off based on a standby command from the center. Then, a control process for interrupting (stopping) the output of the battery 41 will be described with reference to the flowchart of FIG.

When the power supply device 19 is turned off (standby) based on a standby command from the center, the control circuit 35 of the main power supply unit 29 sends the control signal to the control unit 42 of the uninterruptible power supply 30.
A standby signal indicating standby is input.

The control unit 42 of the uninterruptible power supply 30 receives a waiting signal from the box and determines that the apparatus is on standby, and further determines whether or not the commercial power supply is alive and determines whether or not a power failure has occurred. (Steps n1 and n2).

If a power failure occurs during standby, a backup power supply for the battery 41 is output to back up the standby power supply, and at the same time, the timer circuit 44
Starts counting time (steps n3 and n4), and determines whether or not the power failure has been recovered (recovered) while the timer is counting based on whether or not the commercial power supply is alive (step n).
5, n6).

If it is determined that the power failure has been restored before the timer circuit 44 has timed out, the power failure is a short-time power failure such as interruption due to a lightning strike, so that the timing operation of the timer circuit 44 is reset. Then, the output of the backup power supply by the battery 41 is shut off, and the process returns (steps n7 and n8).

When the timer circuit 44 has timed out in step n5, it is determined that a long-term power failure such as a breaker being dropped due to maintenance work, and the output of the backup power supply by the battery 41 is cut off. Wait for restoration of the power failure (steps n9 and n10).

When the recovery of the power is determined by monitoring the commercial power, the interruption of the battery 41 is released, the standby power is supplied, and the process returns (step n11).

As described above, when the automatic teller machine 10 is turned off during standby, the commercial power supply (normal power supply) is used.
When the commercial power supply does not recover even when the timer circuit 44 measures a predetermined time when the power failure occurs, the supply of the backup power supply of the uninterruptible power supply 30 to the standby power supply is cut off (stopped). Supply can be eliminated, and a reduction in the capacity and life of the uninterruptible power supply can be prevented.

Further, in a period in which a commercial power supply is likely to suffer a power failure, or in a summer season when lightning frequently occurs and a normal power supply has a high rate of power failure, or in a place or area where the power failure frequently occurs, the set time of the timer circuit 44 is set. Is set longer by the timer setting unit 45 to cope with the situation, a reliable backup against a power failure of the commercial power supply during standby can be performed, and the reliability can be improved.

In correspondence between the configuration of the present invention and the above-described embodiment, the driving device of the present invention corresponds to the automatic teller machine 10 of the embodiment, and similarly, the timer means corresponds to the timer circuit 44. The stopping means corresponds to the function of executing the process of step n9 of the control unit 42. However, the present invention can be applied based on the technical idea described in the claims. It is not limited to only.
