Description

Embodiments of the present invention relate to payment devices , programs and logging methods .

Conventionally, in stores such as supermarkets, a payment device for performing payment processing has been used. The payment device has a function of recording the occurrence of usage status and errors as a log. The log is divided into a plurality of levels according to the level of detail of the information to be recorded, and generally, the higher the level, the more detailed information is set to be recorded. For example, when a trouble occurs, a more detailed log is recorded by setting it to a high level in order to investigate the cause of the trouble.

In this way, the administrator of the payment device has changed the setting to record a more detailed log each time a trouble occurs. In addition, since the administrator has a heavy burden on the CPU and the storage medium for recording more detailed logs, the administrator has returned to the low level setting when the investigation of the cause of the trouble is completed. However, the administrator has to change the setting every time a trouble occurs in the payment device, which is complicated.

An object to be solved by the present invention is to provide a payment device, a program, and a logging method capable of changing the event of logging.

The payment device of the embodiment includes a recording means and a changing means. The recording means records an event that has occurred in its own device as a log based on one of the log recording levels divided into a plurality of stages so that the types of events to be recorded are gradually increased. The changing means includes the condition of the log recording level to be changed when an abnormality is detected, the log recording level after the change, and the processing in which the abnormality is detected for each type of abnormality related to the operation of the own device. When an abnormality that has occurred in the own device is detected based on the level change condition table that defines the log recording level after the processing is completed , and the current log recording level satisfies the above conditions. , The log recording level of the log recorded by the recording means is changed to the changed log recording level corresponding to the detected abnormality. Before type recording means, said changing means on the condition that changed the logging level by having detected the abnormality occurring in the own device, and records the log of the abnormality in the logging level after the change. The changing means changes to the log recording level after the processing corresponding to the abnormality is completed, on condition that the processing for detecting the abnormality is completed.

The payment device 1 includes a printing unit 113 (see FIG. 2) that prints payment-related information, sales reports, and the like on the above-mentioned receipt paper inside the main body 11. The payment device 1 issues the printed receipt paper from the receipt issuing port 17 provided between the main body 11 and the upper surface panel 13.

Next, the hardware configuration of the payment device 1 will be described.

FIG. 2 is a block diagram showing an example of the hardware configuration of the payment device 1. The payment device 1 includes a control unit 100 for controlling each unit. The control unit 100 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, and a RAM (Random Access Memory) 103. The CPU 101 connects the ROM 102 and the RAM 103 via a bus line 104 such as an address bus and a data bus. The CPU 101 expands the program stored in the ROM 102 and the storage unit 105 into the RAM 103. The CPU 101 controls the payment device 1 by operating according to the program expanded in the RAM 103.

The control unit 100 connects the storage unit 105, the controller 106, and the communication interface 107 via the bus line 104.

The storage unit 105 is a non-volatile memory such as a flash memory that retains storage information even when the power supply is cut off. The storage unit 105 stores the control program 108, the log recording level table 109, the level change condition table 110, the initial value information 111, and the log recording setting information 112.

The control program 108 is a program for exerting the functions provided in the operating system and the payment device 1. The control program 108 includes a program that exerts a characteristic function according to the present embodiment.

FIG. 3 is an explanatory diagram showing an example of the data structure of the log recording level table 109. The log recording level table 109 is an information table divided into a plurality of stages so that the types of events to be recorded in the log are gradually increased. The log recording level table 109 stores the log recording level and the recording event in association with each other. The log recording level is a level value when the level is divided into a plurality of stages so that the types of events to be recorded are gradually increased. The recorded event is the content of the event to be recorded in the log.

The log recording level table 109 of FIG. 3 shows the recording events from level 1 to level 4. Level 1 logs the date and time when the power of the payment device 1 is turned on or turned off, the date and time when a fatal error occurs, the error code of the fatal error, and the like. The fatal error is an error or the like that the payment device 1 cannot operate. An error code is identification information that can identify an error. In level 2, in addition to the events recorded in the log at level 1, the date and time when a minor error occurs and the error code of the minor error are recorded in the event. Minor errors are non-fatal errors. More specifically, the minor error is a partial error in the function of the payment device 1. For example, minor errors include communication errors in communication, timeout errors indicating that a predetermined period has elapsed, file read / write errors, and the like. At level 3, in addition to the events recorded in the log at level 2, information indicating the content of the process executed at the time of error occurrence, recording of data used in the process, and the like are recorded in the log. At level 4, in addition to the events recorded at level 3, operation records and the like are recorded in the log. In this way, the log recording level table 109 is divided into levels so that the types of events to be recorded gradually increase, and the higher the level, the greater the amount of information to be recorded. Although the log recording level table 109 according to the present embodiment shows up to level 4, the log recording level table 109 may have level 5 or higher.

FIG. 4 is an explanatory diagram showing an example of the data structure of the level change condition table 110. The level change condition table 110 is an information table that stores change conditions for changing the logging level. The level change condition table 110 stores the change condition code, the change condition, and the change content in association with each other. The change condition code is identification information that can identify the change condition that changes the logging level. The change condition is a condition for changing the logging level. For example, the change condition is that an abnormality such as an error that has occurred in the payment device 1 itself has been detected. The content of the change is the content of the change in the logging level when the change conditions are met.

The level change condition table 110 of FIG. 4 shows L001, L002, L003, and L004. The change condition related to L001 is that the error code of the error caused by the operation error is detected. The change content related to L001 is to change the log recording level to level 4 when an operation similar to an operation error is detected in order to record the operation content. The change condition relating to L002 is that an error code of an error due to receiving incorrect data in the communication process is detected. The change content related to L002 is changed to level 3 when the log recording level is level 2 or lower in order to record the data content. Further, the content of the change relating to L002 is to change the log recording level to the level before the change after the communication processing is completed. The change condition of L003 is that an error code indicating a timeout error is detected. Since there is a possibility that another error has occurred, the change content of L003 is changed to level 2 when the log recording level is level 1. The change condition of L004 is that an error code indicating a file reading error is detected. The change contents of L004 are changed to level 3 when the log recording level is level 2 or less when the file read or write process is executed. Further, the change content of L004 changes the log recording level to the level before the change after the read or write process is completed. Although the level change condition table 110 according to the present embodiment shows four change conditions, the level change condition table 110 may have five or more change conditions and change contents.

The initial value information 111 stores a log recording level to be set when it is initialized. Here, the initialization is, for example, an activation process in which the payment device 1 is turned on and activated. The initialization is not limited to the activation process, and may be a process when an operation for initializing the payment device 1 is input. It is assumed that the log recording level level 1 is set in the initial value information 111 according to the present embodiment. However, any logging level can be set in the initial value information 111. Further, the initial value information 111 is not limited to the log recording level, and a specific event may be set.

The log recording setting information 112 is information indicating a setting value of the current log recording level. That is, the log recording setting information 112 is information indicating one log recording level selected from the log recording levels divided into a plurality of stages so that the number of events to be recorded increases stepwise.

The controller 106 connects the display unit 14, the touch panel 15, the card reading unit 16, and the printing unit 113. The controller 106 controls various connected hardware based on a command from the control unit 100.

The printing unit 113 includes a platen roller and a printing head. The platen roller pulls out and conveys the receipt paper stored inside the main body 11 by rotating it. The print head is, for example, a thermal head. The print head prints the details of the product purchased by the customer on the receipt paper conveyed by the platen roller.

The communication interface 107 is an interface for communicating with each device via a network such as the Internet.

Next, the characteristic functions of the payment device 1 will be described. Here, FIG. 5 is a block diagram showing a characteristic functional configuration included in the payment device 1.

The print control unit 1004 controls the print unit 113 to print various information on the receipt paper.

The communication control unit 1005 controls the communication interface 107 to communicate with one or more devices connected via a network. That is, the communication control unit 1005 receives input of various information via the network. Further, the communication control unit 1005 outputs various information via the network.

The sales registration unit 1006 controls the sales registration process for registering the product to be sold in the sales data processing. That is, when the operation control unit 1002 receives the product code or the like that can identify the product, the sales registration unit 1006 registers the product with the specified product code as sales. In addition, the sales registration unit 1006 calculates the total price of the products for which sales have been registered for one transaction.

The accounting processing unit 1007 executes the accounting processing of the product to be sold in cooperation with the card reading unit 16. Here, the accounting process is, for example, a process of paying the price of a product or the like by an electronic payment service or the like in one transaction.

The log recording unit 1008 functions as a recording means according to the present embodiment. The log recording unit 1008 records an event that has occurred in the settlement device 1 as a log based on the log recording level set in the log recording setting information 112. More specifically, the log recording unit 1008 generates a log indicating a recording event that has occurred on the condition that a recording event at the log recording level set in the log recording setting information 112 has occurred in the settlement device 1. Then, the log recording unit 1008 stores the generated log in the storage unit 105 or the like.

The log output unit 1009 outputs the log stored in the storage unit 105 or the like by the log recording unit 1008. The log output unit 1009 outputs a log by various methods. For example, the log output unit 1009 outputs a log by causing the communication interface 107 to transmit a log in cooperation with the communication control unit 1005. Further, the log output unit 1009 outputs a log by displaying the log on the display unit 14 in cooperation with the display control unit 1003. Further, the log output unit 1009 outputs a log by causing the print unit 113 to print a log in cooperation with the print control unit 1004.

The setting changing unit 1010 functions as a first changing means according to the present embodiment. The setting change unit 1010 changes the event to be recorded as a log by the log recording unit 1008. That is, the setting change unit 1010 changes the log recording setting information 112.

For example, when the change condition specified in the level change condition table 110 is satisfied, the setting change unit 1010 changes to the log recording level shown in the change contents of the level change condition table 110. For example, the setting change unit 1010 changes the event to be recorded as a log by the log recording unit 1008 to the event corresponding to the detected abnormality on condition that the payment device 1 itself detects an abnormality such as an error. Further, when the change content of the level change condition table 110 stipulates that the log recording level be returned after the processing is completed, the setting change unit 1010 changes to the log recording level before the change. For example, the setting change unit 1010 returns the event to be recorded as a log by the log recording unit 1008 to the event before the change, on condition that the process of detecting the abnormality set in the change content is completed.

Here, the setting change unit 1010 logs the detected event such as an abnormality at the changed log recording level on the condition that the log recording level is changed by detecting an event such as an abnormality that has occurred in the own device. Have the recording unit 1008 record the log. For example, L002 of the level change condition table 110 shown in FIG. 4 indicates that the log recording level is changed to level 3 when an error code indicating an error due to receiving incorrect data in the communication process is detected. ing. Then, level 3 of the log recording level table 109 shown in FIG. 3 is set to record data used in the processing as well. That is, when the setting change unit 1010 changes to level 3 due to an error caused by receiving erroneous data in the communication process, the log recording unit 1008 also records the erroneous data as a log.

The setting change unit 1010 according to the present embodiment determines whether or not the change condition is satisfied based on the log recorded by the log recording unit 1008. For example, the setting change unit 1010 detects an abnormality such as an error from the log recorded by the log recording unit 1008. However, the setting change unit 1010 may determine whether or not the change condition is satisfied by another method, not limited to the detection from the log. For example, when the setting change unit 1010 is provided with a sensor in each part of the payment device 1, it may determine whether or not the change condition is satisfied by the output from the sensor.

Further, when the setting change unit 1010 receives the input for changing the log recording level, the setting change unit 1010 sets the log recording level specified in the input in the log recording setting information 112. Here, the input for changing the logging level is accepted by various methods. For example, the operation control unit 1002 and the communication control unit 1005 function as input means for receiving an input for changing the log recording level. More specifically, the operation control unit 1002 accepts an operation of changing the log recording level. Further, the communication control unit 1005 receives information for changing the log recording level. Then, the setting change unit 1010 changes to the log recording level received by the operation control unit 1002 and the communication control unit 1005.

The initial value setting unit 1011 functions as a second changing means according to the present embodiment. The initial value setting unit 1011 changes the log recording level stored in the initial value information 111 to the log recording setting information 112 on condition that a specific event has occurred. For example, the specific event is an activation process that activates the payment device 1 itself. Further, the specific event is an initialization process executed when an operation for initializing the payment device 1 is input.

Here, level 1 of the log recording level is set in the initial value information 111 of the present embodiment. Further, when an abnormality such as an error occurs in the settlement device 1, the log recording level level 2 or higher is set in the log recording setting information 112. That is, the initial value setting unit 1011 sets a log recording level lower than the log recording level changed by the setting change unit 1010 on condition that a specific event such as startup processing has occurred. Therefore, even if an abnormality such as an error occurs in the settlement device 1 and the log recording level is raised, the initial value setting unit 1011 records the initial value information 111 as the log recording setting information by restarting the settlement device 1. Since it is set to 112, the logging level can be lowered. That is, since the initial value setting unit 1011 can reduce the types of events to be recorded by the log recording unit 1008 as compared with those before the change, the burden on the CPU 101, the storage unit 105, and the like can be reduced.

Next, the level change process executed by the payment device 1 will be described. Here, FIG. 6 is a flowchart showing an example of the level change process executed by the payment device 1 of the embodiment.

The activation control unit 1001 of the payment device 1 activates the payment device 1 (step S1).

The log recording unit 1008 of the payment device 1 generates a log of an event generated by executing various processes in step S3 (step S4). The log recording unit 1008 of the payment device 1 stores the generated log in the storage unit 105 or the like (step S5).

The setting change unit 1010 of the payment device 1 determines whether or not the conditions specified in the change conditions of the level change condition table 110 are satisfied based on the log stored in the storage unit 105 or the like (step S6).

On condition that the conditions specified in the change conditions of the level change condition table 110 are satisfied (step S6; Yes), the setting change unit 1010 of the payment device 1 is specified in the change conditions of the level change condition table 110. Change to a level (step S7). Further, when the change condition of the level change condition table 110 stipulates that the level be returned to the level before the change after the processing is completed, the setting change unit 1010 changes the level after the processing is completed. Return to. Then, the payment device 1 shifts to step S3.

On the other hand, on the condition that the condition specified in the change condition of the level change condition table 110 is not satisfied (step S6; No), the initial value setting unit 1011 of the settlement device 1 sets the initial value information 111. Is satisfied or not (step S8).

The payment device 1 proceeds to step S3 on condition that the condition for setting the initial value information 111 is not satisfied (step S8; No). On the other hand, on condition that the condition for setting the initial value information 111 is satisfied (step S8; Yes), the settlement device 1 proceeds to step S2.

Then, the payment device 1 ends the level change process when the power is cut off at any step.

As described above, according to the payment device 1 according to the present embodiment, the log recording unit 1008 indicates the content of the event that occurred when the event of the log recording level set in the log recording setting information 112 occurs. Generate a log. The operation control unit 1002 or the like changes the log generation level of the log recording setting information 112 when the operation control unit 1002 receives an operation or the like for changing the log generation level of the log recording setting information 112. Then, the initial value setting unit 1011 sets the initial value information 111 in the log recording setting information 112 when a specific event such as an activation process for activating the payment device 1 occurs. Therefore, the payment device 1 can change the event of recording the log without the operation of the administrator. That is, since the payment device 1 changes the setting of the target for generating the log without the operation of the administrator, the log recording level is changed even if the administrator forgets to change the log recording level. Can be done.
