Description

The present invention relates to a transaction device and a monitoring method.

A building in which a transaction device such as an ATM (Automated Teller Machine) is installed may be inundated due to a natural disaster such as a typhoon or a tsunami. In the transaction apparatus, the control unit is often located near the bottom surface because of the configuration of various units such as a bill processing unit and a card processing unit. For this reason, if the building in which the ATM is installed is flooded, damage such as data loss may occur early. On the other hand, it has been proposed to store the transaction information stored only in the own device in a backup storage unit above the ATM device.

However, a short circuit due to water immersion may occur inside the ATM, an abnormal current may flow, and an unexpected power failure may occur. For this reason, the data in the backup storage unit may be destroyed, resulting in data loss.

One aspect is to provide a transaction device and a monitoring method capable of preventing data loss.

In one aspect, the transaction device includes an acquisition unit, a determination unit, a detection unit, and a control unit. The acquisition unit acquires the detected water level from a water level sensor that detects the water level from the floor surface. The determination unit determines whether the acquired water level is less than a first predetermined value, or whether the acquired rising rate of the water level is a second predetermined value or more. As a result of the determination, the detection unit determines that the acquired water level is equal to or higher than the first predetermined value, or determines that the acquired rising rate of the water level is equal to or higher than the second predetermined value. First, it is detected that the water is flooded. The control unit shuts down the operating system when the detection unit detects that the water is flooded.

Data loss can be prevented.

The water level sensor 18 measures the water level from the floor where the ATM 1 is installed. The water level sensor 18 can measure the time change of the water level by various methods such as a capacitance method and a resistance method. The water level sensor 18 outputs the measured water level h to the control unit 20.

The power board 19 is a power supply unit that supplies power to the ATM 1. The power board 19 supplies power to each unit and each unit of the ATM 1. For example, the power board 19 supplies an operating system (hereinafter, also referred to as OS) power supply and a standby (hereinafter, also referred to as STB) power supply to the control unit 20.

The control unit 20 controls the operation of the entire ATM 1. The control unit 20 includes an SSD/HDD (Solid State Drive/Hard Disk Drive) 21a, a RAM (Random Access Memory) 22, a CPU (Central Processing Unit) 23, a communication control unit 24, an input/output interface 25, and It has a graphic processing unit 26, a water immersion detection unit 27, and an OS power supply monitoring unit 29. In addition, the control unit 20 executes a flood control process. In this case, it is assumed that the input of the flood detection signal from the flood detection unit 27 to the control unit 20 is an input to the process of the flood control process executed by the control unit 20.

The SSD/HDD 21a is an example of the storage unit 21. The SSD/HDD 21a stores transaction information and journal data such as logs relating to the operation of the ATM 1. In addition, the SSD/HDD 21a stores programs and information used for processing in the control unit 20.

The RAM 22 is an example of a main storage device. As the RAM 22, for example, DDR4 SDRAM (Double-Data-Rate 4 Synchronous Dynamic Random Access Memory) can be used. In the RAM 22, the programs stored in the SSD/HDD 21a are read and expanded by the CPU 23, so that the CPU 23 executes various processes.

The CPU 23 is an example of a central processing unit. The CPU 23 executes various programs by executing the programs stored in the SSD/HDD 21a by using the RAM 22 as a work area.

The inundation detection unit 27 acquires the water level detected by the water level sensor 18 and detects inundation due to a natural disaster (hereinafter, also referred to as flood damage) such as a typhoon or a tsunami. When the inundation detection unit 27 detects inundation due to water damage, it outputs an inundation detection signal to the power supply control unit 30.

The external recording medium 28 is a recording medium for backing up journal data and the like. The external recording medium 28 has, for example, a drive of an optical medium such as a DVD or a BD (Blu-ray (registered trademark) Disc) and a corresponding optical medium.

The OS power supply monitoring unit 29 monitors the state of the OS operating in the control unit 20. When detecting that the OS has been shut down, the OS power supply monitoring unit 29 outputs an OS disconnection signal to the power supply control unit 30.

The power supply control unit 30 controls the connection of the power supply panel 19 to an external power supply line based on the flood detection signal and the OS disconnection signal.

Next, the functional configuration relating to the water immersion detection will be described with reference to FIG. As shown in FIG. 4, the water level sensor 18, the power supply panel 19, the external recording medium 28, and the power supply control unit 30 are connected to the control unit 20 of the ATM 1. The power board 19 is also connected to the power control unit 30. The water immersion detection unit 27 of the control unit 20 includes an acquisition unit 271, a determination unit 272, and a detection unit 273.

The acquisition unit 271 acquires the water level h detected by the water level sensor 18. The acquisition unit 271 acquires the water level h detected by the water level sensor 18 for each water level reading cycle Δt (for example, 5 seconds). The acquisition unit 271 outputs the acquired water level h to the determination unit 272.

Here, the water level and the rising speed of the water level will be described with reference to FIGS. 5 and 6. FIG. 5 is a diagram showing an example of the water level. As shown in FIG. 5, in the case of flooding from the lower part of the ATM 1, it is required to detect the water level and the rising speed of the water level before the water level reaches the power board 19. In the example of FIG. 5, the water level sensor 18 detects the water level h and outputs it to the control unit 20. When it is determined that the water level h is equal to or higher than the first predetermined value, the control unit 20 detects the inundation and executes the inundation countermeasure process.

FIG. 6 is a diagram showing an example of calculation of the rising speed of the water level. As shown in FIG. 6, the rising rate RS of the water level h is based on the difference Δh between the water level h at the time t detected by the water level sensor 18 and the water level h′ at the time t′ after the read cycle Δt from the time t. Can be calculated. When it is determined that the rising speed RS is equal to or higher than the second predetermined value, the control unit 20 detects the inundation and executes the inundation countermeasure process.

Returning to the description of FIG. 4, the determination unit 272 determines whether or not the water level h is input from the acquisition unit. That is, the determination unit 272 determines whether or not the water level h is detected at the time t. When determining unit 272 determines that water level h is not detected at time t, determination unit 272 continues to wait for input of water level h. When determining that the water level h is detected at the time t, the determination unit 272 determines whether the water level h is less than the first predetermined value H1. When it is determined that the water level h is not less than the first predetermined value H1, that is, the water level h is not less than the first predetermined value H1, the determination unit 272 outputs the inundation information to the detection unit 273.

When it is determined that the water level h is less than the first predetermined value H1, the determination unit 272 determines whether or not the water level h′ is detected at the time t′ after the read cycle Δt from the time t. When it is determined that the water level h′ is not detected at the time t′, the determination unit 272 determines that the detection of the water level h is temporary and waits for the input of the water level h.

When determining that the water level h'is detected at the time t', the determination unit 272 determines whether the water level h'is less than the first predetermined value H1. When the determination unit 272 determines that the water level h′ is not less than the first predetermined value H1, that is, is equal to or more than the first predetermined value H1, it outputs the flooding information to the detection unit 273.

When determining that the water level h′ is less than the first predetermined value H1, the determination unit 272 determines whether the water level h′ exceeds the water level h. When it is determined that the water level h′ is equal to or lower than the water level h, the determination unit 272 determines that the water level h has not risen and waits for the input of the water level h.

When determining that the water level h′ exceeds the water level h, the determination unit 272 calculates the rising rate RS of the water level h. The rising speed RS can be calculated by the following equation (1).

RS=(h'-h)/(t'-t) (1)

The determination unit 272 determines whether or not the calculated rising speed RS is equal to or higher than a predetermined rising speed S. When it is determined that the rising speed RS is less than the predetermined rising speed S, the determination unit 272 determines that the rising speed RS of the water level h is not so high and waits for the input of the water level h. The rising speed S is an example of the second predetermined value.

When determining that the rising speed RS is equal to or higher than the predetermined rising speed S, the determining unit 272 outputs the flooding information to the detecting unit 273.

When the inundation information is input from the determination unit 272, the detection unit 273 detects that the inundation is due to water damage. When the detection unit 273 detects that the water is inundated due to water damage, it outputs an inundation detection signal to the control unit 20 and the power supply control unit 30.

Here, an example of calculation of the rising rate RS of the water level h will be described. First, the read cycle Δt is 5 seconds. It is assumed that the water immersion detection unit 27 detects the water level h=0.5 mm at the time t. It is assumed that the water immersion detection unit 27 detects the water level h'=5.5 mm at time t'after 5 seconds from time t. In this case, the water immersion detection unit 27 calculates the difference Δh between the water levels h at time t and time t′ as Δh=(5.5−0.5)=5 mm based on Δh=(h′−h). To do. Further, since the water immersion detection unit 27 has (t′−t)=Δt, the rising speed RS is calculated as S1=5 mm/5 seconds=1 mm/second.

For example, assuming that the first predetermined value H1=100 mm, the water intrusion detection unit 27 determines that the water level h or the water level h′ is equal to or greater than the first predetermined value H1 regardless of the value of the rising speed RS. The detection signal is output to the control unit 20 and the power supply control unit 30. Further, when the inundation detection unit 27 determines that the calculated ascending speed RS is not less than the predetermined ascending speed S, for example, when the ascending speed S is 1 mm/sec. 20 and the power supply control unit 30.

Further, the time that can be used for the inundation countermeasure process is (150 mm-5.5 mm)/when the height of the current-carrying part, for example, the height from the floor surface to the power board 19 in FIG. 5 is 15 cm. 1 [mm/sec])=144.5 seconds can be calculated.

Next, a flooding detection screen when a flooding detection signal is input to the control unit 20 will be described. FIG. 7 is a diagram showing an example of the water immersion detection screen. When the inundation detection signal is input from the inundation detection unit 27, the control unit 20 displays the inundation detection screen 40 shown in FIG. 7 and executes the shutdown process if the customer waits. If the transaction is in progress, the control unit 20 suspends the transaction, displays the inundation detection screen 40, and executes the shutdown process.

Next, the power supply controller 30 will be described with reference to FIGS. 8 and 9. FIG. 8 is a diagram showing an example of connections between the power supply control unit, the power supply panel, and the control unit. As shown in FIG. 8, the power supply control unit 30 controls the opening/connection (OFF/ON) of the power supply lines L1 and L2 of the power supply panel 19 by using the latch relay 31. The power lines L1 and L2 of the power board 19 are connected to an external power line via a latch relay 31. In addition, the protective ground PE of the power board 19 is directly connected to the external power line without the intermediary of the latch relay 31. The power board 19 supplies the control unit 20 with STB power used during standby and OS power used during operation of the ATM 1. The power supply of the power supply controller 30 is connected to the STB power supply of the power board 19.

The power supply control unit 30 has a power supply control logic 32, and controls the latch relay 31 based on the flood detection signal and the OS disconnection signal input from the control unit 20. The flood detection signal is output when the flood detector 27 of the controller 20 detects flood based on the water level acquired from the water level sensor 18. The OS disconnection signal is output when the OS power monitoring unit 29 in the control unit 20 detects the completion of the OS shutdown.

FIG. 9 is a diagram illustrating an example of the configuration of the power supply control unit. As shown in FIG. 9, the power supply control unit 30 includes a latch relay 31, an AND gate 33, a protection circuit 34, a battery 35, and a switch 36.

The latch relay 31 is a relay that opens/connects (OFF/ON) the power supply lines L1 and L2 of the power supply panel 19. The latch relay 31 is opened when a relay OFF signal is input, and is connected when the switch 36 is pressed. The AND gate 33 outputs a relay OFF signal when both the water immersion detection signal and the OS disconnection signal are "1" (positive logic). The protection circuit 34 is a circuit that protects the AND gate 33 and the like from a high voltage generated when the latch relay 31 is opened. The battery 35 is a power source for controlling the latch relay 31 to make a transition to the connected state when the latch relay 31 is in the open state. The switch 36 is a switch for connecting the battery 35 to the latch relay 31 so that the ATM relay 1 can be powered on when safety is confirmed after the latch relay 31 is opened. The AND gate 33, the protection circuit 34, and the switch 36 are an example of the power supply control logic 32.

(ATM operation)
Next, the operation of the ATM 1 of the first embodiment will be described. First, the water immersion detection process will be described. FIG. 10 is a flowchart illustrating an example of the water immersion detection process according to the first embodiment.

The acquisition unit 271 of the water immersion detection unit 27 acquires the water level h detected by the water level sensor 18. The acquisition unit 271 outputs the acquired water level h to the determination unit 272. The determination unit 272 determines whether or not the water level h is detected at the time t (step S1). When the determination unit 272 determines that the water level h is not detected at the time t (step S1: No), the determination of step S1 is repeated.

When it is determined that the water level h is detected at the time t (step S1: Yes), the determination unit 272 determines whether or not the water level h is less than the first predetermined value H1 (step S2). When the determination unit 272 determines that the water level h is not less than the first predetermined value H1 (step S2: No), it outputs the flooding information to the detection unit 273, and proceeds to step S8. When the determination unit 272 determines that the water level h is less than the first predetermined value H1 (step S2: Yes), the determination unit 272 determines whether or not the water level h'is detected at the time t'(step S3). When the determination unit 272 determines that the water level h'is not detected at the time t'(step S3: No), the process returns to step S1.

When determining unit 272 determines that water level h'is detected at time t'(step S3: Yes), it determines whether water level h'is less than first predetermined value H1 (step S4). When the determination unit 272 determines that the water level h′ is not less than the first predetermined value H1 (step S4: No), it outputs the flooding information to the detection unit 273, and proceeds to step S8. When the determination unit 272 determines that the water level h'is less than the first predetermined value H1 (step S4: Yes), it determines whether the water level h'exceeds the water level h (step S5). When the determination unit 272 determines that the water level h′ is equal to or lower than the water level h (step S5: No), the process returns to step S1.

When the determination unit 272 determines that the water level h'exceeds the water level h (step S5: Yes), the rate of increase RS of the water level h is calculated (step S6). The determination unit 272 determines whether the calculated rising speed RS is equal to or higher than the predetermined rising speed S (step S7). When the determination unit 272 determines that the rising speed RS is less than the predetermined rising speed S (step S7: No), the process returns to step S1. When it is determined that the rising speed RS is equal to or higher than the predetermined rising speed S (step S7: Yes), the determining unit 272 outputs the flooding information to the detecting unit 273.

When the inundation information is input from the determination unit 272, the detection unit 273 detects that the inundation is due to water damage. When the detection unit 273 detects that the water is inundated due to water damage, it outputs an inundation detection signal to the control unit 20 and the power supply control unit 30 (step S8). Thereby, the water intrusion detection unit 27 can detect inundation due to water damage. In addition, the water infiltration detection unit 27 can determine whether the water is inundated due to mischief or when the user spills a drink, or the water inundated due to water damage.

Next, the inundation countermeasure process will be described. FIG. 11 is a flowchart illustrating an example of the flooding countermeasure process according to the first embodiment.

When the inundation detection signal is input from the detection unit 273 (step S10), the control unit 20 determines whether the ATM 1 is in a transaction or waiting for a customer (step S11). When it is determined that the customer is waiting for the customer (step S11: waiting for the customer), the control unit 20 switches the screen displayed on the display unit 15a to the flood detection screen (step S12), and proceeds to step S19.

On the other hand, when the control unit 20 determines that the transaction is in progress (step S11: under transaction), the control unit 20 stops the transaction and switches the screen displayed on the display unit 15a to the flood detection screen (step S13). Next, the control unit 20 determines whether or not the card is in the card processing unit 13, that is, in the card reader (step S14). When the control unit 20 determines that the card is inside the card reader (step S14: Yes), the card is ejected (step S15), and the process proceeds to step S16. The control unit 20 returns the passbook in the same manner when it is determined that the passbook is present in the passbook processing unit 14. When the control unit 20 determines that the card is not in the card reader (step S14: No), the process proceeds to step S16.

The control unit 20 determines whether or not cash remains in the deposit/withdrawal unit (step S16). Here, the deposit/withdrawal unit is the banknote processing unit 16 and the coin processing unit 17. When the control unit 20 determines that the cash remains in the deposit/withdrawal unit (step S16: Yes), the cash is taken in (step S17), and the process proceeds to step S18. When the control unit 20 determines that no cash remains in the deposit/withdrawal unit (step S16: No), the process proceeds to step S18.

The control unit 20 records the transaction information regarding the transaction that was in progress in the storage unit 21 (step S18). The control unit 20 executes a shutdown process (step S19). When detecting that the OS has been shut down, the OS power supply monitoring unit 29 outputs an OS disconnection signal to the power supply control unit 30. As a result, the control unit 20 can shut down the OS when the water immersion is detected. Further, the control unit 20 can protect a unit or the like that is energized during operation.

Next, the power-off process will be described. FIG. 12 is a flowchart illustrating an example of the power shutoff process according to the first embodiment.

The power supply control unit 30 monitors the relay OFF signal which is the output of the AND gate 33 for the inundation detection signal and the OS disconnection signal. The power supply control unit 30 determines whether the relay OFF signal is "0" or "1" (step S20). When the power supply control unit 30 determines that the relay OFF signal is "0" (step S20: "0"), the determination of step S20 is repeated.

When determining that the relay OFF signal is "1" (step S20: "1"), the power supply control unit 30 turns off (opens) the latch relay 31 (step S21). As a result, the power supply control unit 30 also turns off the standby power supply, so that the occurrence of abnormal current can be suppressed and data loss can be prevented. That is, the power supply control unit 30 can protect the entire ATM1 device.

In this way, the ATM 1 acquires the detected water level from the water level sensor that detects the water level from the floor surface. Further, the ATM 1 determines whether the acquired water level is less than the first predetermined value or whether the acquired rising rate of the water level is the second predetermined value or more. In addition, as a result of the determination, the ATM 1 determines that the acquired water level is equal to or higher than a first predetermined value, or the acquired water level rise speed is equal to or higher than a second predetermined value. Detected as being flooded. Further, the ATM 1 shuts down the operating system when the detection unit detects that the water is flooded. As a result, the ATM 1 can prevent data loss.

Further, when the signal indicating the completion of the shutdown of the operating system is input, the power supply control unit 30 of the ATM1 disconnects the latch relay 31 provided on the power supply line of the ATM1 (transaction device). As a result, the ATM 1 can suppress the occurrence of abnormal current and prevent data loss.

In the first embodiment described above, the case where the standby power supply is turned off when the inundation due to water damage is detected has been described, but the journal data and the like may be backed up to the optical medium before the shutdown. Therefore, a second embodiment will be described. In the second embodiment, the same components as those of the ATM 1 of the first embodiment are designated by the same reference numerals, and the description of the duplicated configurations and operations will be omitted.

In the second embodiment, a process is added to the water immersion countermeasure process in the ATM 1 of the first embodiment, so the additional portion will be described. FIG. 13 is a flowchart illustrating an example of the flood control process of the second embodiment.

The control unit 20 executes the next process after switching to the water intrusion detection screen in step S12 or recording the transaction information in step S18. The control unit 20 outputs the journal data and the like stored in the storage unit 21 (SSD/HDD 21a) to the external recording medium 28 and copies it to an optical medium such as a DVD (step S30). When the writing to the optical medium ends, the control unit 20 proceeds to step S19. As a result, the ATM 1 can back up the data, so that the data loss can be further prevented.

As described above, when the detection unit 273 detects the inundation due to water damage, the ATM 1 stores the journal data in the external recording medium and then shuts down the operating system. As a result, the ATM 1 can back up the journal data before shutting down. Therefore, it is possible to further prevent data loss.

Although the optical medium is used as the backup destination of the journal data and the like in the second embodiment, the SSD provided on the upper part of the ATM1 housing may be used as the backup destination. The embodiment in this case will be described as the third embodiment. To do. In the third embodiment, the same components as those of the ATM1 of the first and second embodiments are designated by the same reference numerals, and the description of the duplicated configurations and operations will be omitted.

FIG. 14 is a diagram illustrating an example of the SSD installation position in the ATM of the third embodiment. The ATM 3 shown in FIG. 14 has an SSD 50 in the upper part of the housing as compared with the ATM 1 of the first and second embodiments.

The SSD 50 is an SSD that is sealed and waterproofed. The SSD 50 corresponds to the external recording medium 28 of the second embodiment, and is connected to the control unit 20 by various interfaces such as a USB (Universal Serial Bus) provided in the input/output interface 25, for example. When the controller 20 of the ATM 3 detects the inundation due to the water damage based on the water level detected by the water level sensor 18, the journal data and the like stored in the storage 21 (SSD/HDD 21a) is input via the input/output interface 25. Copy to SSD50. When the writing to the SSD 50 is completed, the control unit 20 executes a shutdown process. After that, the power supply control unit 30 controls the latch relay 31 to cut off the power supply line of the power supply panel 19.

Note that the storage unit 21 is disposed near the control unit 20 during normal operation and performs cooling by an appropriate air flow, so it is difficult to dispose the storage unit 21 itself in the upper part of the housing. On the other hand, since the SSD 50 operates during backup, there is no problem in operation even if it is sealed.

According to the second and third embodiments, the external recording medium 28 is an optical medium or a solid state drive installed above the ATM 3 (transaction device). As a result, the ATM 1 and 3 can back up the journal data before shutting down. Therefore, it is possible to further prevent data loss.

In the third embodiment, the SSD provided on the upper part of the housing is used as a backup destination, but the storage unit 21 may be waterproofed. An embodiment in this case will be described as a fourth embodiment. .. In the fourth embodiment, the same components as those of the ATM 1 of the first and second embodiments are designated by the same reference numerals, and the description of the duplicated configurations and operations will be omitted.

FIG. 15 is a diagram showing an example of waterproofing processing in the ATM of the fourth embodiment. The storage unit 21b illustrated in FIG. 15 is cooled by an air flow using a ventilation port during a normal operation. The storage unit 21b is arranged in the vicinity of the control unit 20 in the lower part of the housing, similarly to the storage unit 21 of the first embodiment. When the inundation due to water damage is detected, the storage unit 21b performs the waterproofing process by closing the vent hole with the shutter 51. The shutter 51 is provided with packing, for example, and is waterproofed by being pressed against the ventilation port of the storage unit 21b by a spring or the like. Further, instead of the shutter 51, a box whose lower surface is opened is provided above the storage unit 21b, and when the water is detected, the storage unit 21b is covered with the box to ensure air around the storage unit 21b. It may be a structure.

In the fourth embodiment, instead of the process of copying the journal data and the like in the second embodiment to the DVD, a waterproof process is performed on the storage unit 21b, so the changed part will be described. FIG. 16 is a flowchart illustrating an example of the flood control process of the fourth embodiment.

The control unit 20 executes the next process after switching to the water intrusion detection screen in step S12 or recording the transaction information in step S18. The control unit 20 operates the shutter 51 to perform waterproof processing on the storage unit 21b (SSD/HDD) (step S31). When the waterproofing process ends, the control unit 20 proceeds to step S19. As a result, the ATM 1 protects the SSD/HDD of the storage unit 21b from water intrusion, so that data loss can be prevented.

In this way, the ATM 1 performs the waterproof process on the storage unit 21b that stores the journal data when it is detected that the water is flooded. As a result, the SSD/HDD of the storage unit 21b is protected from water infiltration, so that data loss can be prevented.

In each of the above embodiments, the ATM is used as the transaction device, but the present invention is not limited to this. For example, the present invention can be applied to a device such as a vending machine that normally operates unattended and may be flooded due to water damage.
