Description

Description: TECHNICAL FIELD The present invention relates to a date setting device that is connected to a center in a financial institution or the like by a communication line and sets a date sent from the center to an online terminal device or the like.

(Prior Art) A date used in a business executed by an online terminal device such as a financial institution is particularly important because it serves as a basis for interest calculation. Therefore, financial institutions and the like require particularly careful handling of dates. For this reason, the date is not set in each online terminal device, but is obtained from a center managing business.

FIG. 2 is a block diagram showing a configuration of an online terminal device 10 using a conventional date setting device.

The illustrated device includes a memory 22, a date file 23, and a line controller 24 connected to a bus line 20 of a processor 21.

The processor 21 is a device that performs data processing, various controls, and the like.

The memory 22 is a circuit composed of a RAM (random access memory) or the like, and stores data and parameters necessary for executing a program.

The date file 23 includes an external storage device that stores business days sent from the center 31 via the communication line 30 and the line control unit 24.

The line control unit 24 is a circuit that controls data communication with the center 31 via the communication line 30.

Next, the operation of the above-described date setting device will be described. There are two modes of operation of the device described above.

In the first method, the business day is transmitted from the center 31 by turning on the power of the terminal device 10 before starting the business. That is, if today is a business day, today's date is transmitted, and if today is not a business day, no date is transmitted. When the date is transmitted from the center 31, the terminal device 10 is activated and business is started. The transmitted date is stored in the date file 23 of the terminal device 10. This date is used for interest calculation, passbook entry, and the like.

In the second method, the next business day is transmitted from the center 31 at the end of the business. For example, if the next day is a business day, the date of the next day is transmitted. If the next day is a holiday and the next day is a business day, the date of the next day is transmitted. The date sent is
It is stored in the date file 23 of the terminal device 10. Then, when the terminal device 10 is started on the next business day, this date is used for interest calculation, passbook entry, etc.
No. 25089).

(Problems to be solved by the invention) However, the date setting device described above has the following problems.

That is, the first method described above has a problem that if the communication line 30 or the center 31 is down when the terminal device 10 is started, the date cannot be received from the center 31 and business cannot be started. Was.

Further, in the above-described second method, for example, when the terminal device 10 is not activated at the next operating ratio and the terminal device 10 is activated at the next operating ratio, there is a problem that the date is shifted. .

The present invention has been made in view of the above points, and it is an object of the present invention to provide a date setting device that ensures that an accurate date is set at the time of startup.

(Means for Solving the Problems) A date setting device according to the present invention is a date setting device for setting a date on a terminal device connected to a business management center via a communication line. Current date means to obtain, a date file storing a plurality of business days received from the center, and a difference between the number of years when the date of one of the plurality of business days of the date file and the current date data match. An offset value setting unit that sets an offset value; and, when a date obtained by subtracting the offset value from a current date of the current date unit matches one of a plurality of business days in the date file, the date is set to a business day of the terminal device. Date setting means for setting the date of the day.

(Operation) In the device of the present invention, the offset value setting means compares the current date of the current date means, for example, the current date of West History with the corresponding business day date of Japanese History in the date file, Is set as the offset value. That is, the difference between the years of the West History and the Japanese History is set as the offset value.

Then, the date setting means subtracts the offset value from the current date, compares the subtracted historical date with a plurality of business day dates in the date file, and subtracts the historical date. If matches any of the business days, this date is set as the business day date. Therefore, even when a business day cannot be received from the center, the business day date can be set, and the business day date is set only when a business day that matches the current date is present in the date file. Can be prevented from becoming inaccurate. Further, since the business day date is set using the offset value, for example, even when the era is changed, the terminal device can automatically switch to the new era without any change operation.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the date setting device of the present invention.

The device shown in the figure comprises a line control unit 1, a date file 2, a current date means 3, an offset value setting means 4, a date setting means 5, a station opening time control means 6, and a start control means 7, The terminal device 100 having these configurations is connected to the communication line 30.
Is connected to the center 31 via the.

The line control unit 1 includes a known communication control circuit that controls data communication with the center 31 via the communication line 30.

The date file 2 is a non-volatile storage device for storing a plurality of historical business dates sent from the center 31 via the communication line 30 and the line control unit 1, and is composed of a magnetic disk device or the like. That is, when today is a business day, the date file 2 stores not only today's date but also the previous day and business days after the next business day. For example, when storing business days for one week, all business days except holidays from Monday to Friday are stored. The same applies to the case where two or more business days are stored.

The current date means 3 is composed of a known electronic timepiece or the like, and outputs the current date data in a western history as a reference time at which the number of years changes continuously. It is well known that such current date means 3 can transmit extremely accurate date data at present, and its accuracy is about 10 seconds per month. Therefore, it is rare for the date to be out of order, and it is sufficient to confirm the date about once a year.

The offset value setting means 4 comprises a processor or the like,
The date of the current date data of the current date means 3 and the date when the date coincides with any of a plurality of business days in the date file 2 are compared, and the difference between the years is set as an offset value. That is, the difference between the Western history and the Japanese history of the current date is the offset value.

The date setting means 5 comprises a processor or the like, and inputs the current date data of the current date means 3 and the offset value of the offset value setting means 4 and subtracts the offset value from the current date data to calculate the sum history current date. If the current date of the Japanese history matches any of the business days in the date file 2, the current date is set as the business day date. Also,
At the start of the next business day, control is performed to shift the business day date in the date file 2 by one day.

The start-up control means 6 comprises a processor or the like, like the date setting means 5, controls the start-up message from the center 31, checks the business day date in the start-up message with the business day date in the date file 2, and It updates the business days in the file 2 and controls the activation control means 7 described later. That is,
The business day date in the date file 2 shifted by the date setting means 5 is updated with the business day date from the center 31, and
If the current date in the date file 2 does not coincide with the business day current date from the center 31, a signal is sent to the activation control means 7 to shut down the system.

The activation control means 7 is constituted by a processor similarly to the date setting means 5 and the like, and activates the terminal device 100 when the business day date is set by the date setting means 5, and when the business day date is not set and when the station is opened. If there is an instruction to shut down the system by means 6, control is exercised so that the terminal device 100 is not activated.

 Next, the operation of the date setting device will be described.

First, when the terminal device 100 is started, in a normal operation, first, the business day date in the date file 2 is shifted by one day, such as current day → previous day, next day → current day. Next, the date setting means 5 subtracts the offset value of the offset value setting means 4 from the western history current date data from the current date means 3 to calculate a sum history current date. The date and date are determined by an algorithm described later, and when these dates match, the date is updated as business day data in the date file 2 in the date file 2. At the same time, an activation signal is sent to the activation control means 7 to activate the terminal device 100.

Thereafter, the center 31 is opened, and the opening time control means 6 receives business day date data for a predetermined number of days as center data. Next, the start-of-station control means 6 compares the received business day date data with the business day date data stored in the date file 2, updates the data in the date file 2 with the center data, and checks the result of the comparison. If the business day dates do not match, a stop instruction signal is sent to the activation control means 7, and the activation control means 7
System down.

FIG. 3 is a diagram showing an algorithm for setting a business date when the terminal device 100 is started up.

In order to avoid the complexity of the operation description, in this embodiment, the number of days for storing business days in the date file 2, that is, the number of days for storing business days decided between the center 31 and the terminal device 100 is assumed to be four days. explain. In addition, of the four columns of the date file, the business day dates of the previous day, the current day, the next day, and the next two days are shown in order from the top.

First, in the case of No. 1, all dates in date file 2 are 0
It is. That is, in this case, this is the state at the first start-up without receiving business day date data from the center 31. Therefore, in this case, since this is the initial setting process, a process different from the normal process is performed, and the current date (November 24, 1988
Day) and an offset value (25), and the business day date in the date file 2 is set to be November 24, 1988.

In the case of No. 1 described above, if there is an input error on the terminal device 100 side, since the business day date in the date file 2 does not match the business day date in the center data, the operation by the station opening control means 6 is performed. The system goes down.

Next, the case of No. 2 is a case where the current date of the Japanese history (current date−offset value) matches the business day date in the date file 2. In this case, for example, the current of the terminal device 100 is temporarily reduced, and the terminal device 100 is restarted during the day. Therefore, the business date data in the date file 2 is not shifted, and the terminal device 100 is started as it is on the business day date of November 24, 1988.

In the case of No. 3, the date of the next business day in the date file 2 is stored (November 25, 1988), and the current date of the Japanese history matches the date of the next business day. Date is not stored. That is, in this case, the business day is not received from the center 31 for one day.

Therefore, the date setting means 5 updates the data in the date file 2 using the current date of the Japanese history as the business day date.

In the case of No. 4, the date of the next business day in the date file 2 is stored (November 25, 1988), and the current date of Japanese history (November 26, 1988) is the date of the business day (Showa November 63
24th) and the date after the next business day.

This state indicates that although the business day is November 25 as the center data, the terminal device 100 was not activated on November 25. Therefore, the date setting means 5 performs processing to shift the business day date of the date file 2 by two days. The day before the shift after the shift is November 25
November 24, when the terminal device 100 originally started
If the date is the day before the business day, it is only necessary to configure the terminal device 100 to be able to distinguish between the activation date and the non-activation date, and to store only the activation date in the date file 2.

In the case of No. 5, the business day date in date file 2 is stored (November 22, 1988), and the current date of Japanese history (November 23, 1988) is the business day date and business day. This is the case when it is located between the next day's date (November 24, 1988). That is, the date corresponding to the current date does not exist in the date file 2.

In this case, the day when the terminal device 100 is not activated,
The date setting means 5 performs the holiday operation without performing the processing.

No. 6 is a case other than No. 1 to No. 5, and in this case, a date setting error indicates that the terminal device 100 is not activated.

Next, an operation when the business date is received from the center 31 after the terminal device 100 is started will be described.

FIG. 4 is a diagram showing an algorithm when the center 31 is opened.

First, the case of No. 1 is a case where all the business day dates sent from the center 31 are earlier than the business day dates in the date file 2.

Therefore, since such a state cannot usually occur, the station opening control means 6 determines that a center date error has occurred, and the activation control means 7 causes the terminal device 100 to shut down the system.

Next, the case of No. 2 indicates a normal operation. In other words, the business day date in the date file 2 is shifted one day ahead of the date, and there is no date data two days later. Then, new business day date data is sent from the center 31 and the business day date from the center 31 matches the business day date in the date file 2.

Therefore, in this case, the business day date in the date file 2 is updated with the data from the center 31, and the business day date is set to four days.

In the case of No. 2, the era of the Japanese history has changed since November 22. Therefore, the offset value setting means 4 subtracts the business day date (011122) of the updated date file 2 from the current date (881122) from the current date means 3 and updates the offset value to 87. When the date is set, the offset value setting means 4 always calculates the difference in years between the current date of the Christian era of the current date means 3 and the Japanese business day date in the date file 2.

Therefore, even if the era changes, there is no need to perform any operation such as re-input of the set value of the current date means 3, and the business day date is automatically set by the new era.

Further, in the case of No. 3 other than the above Nos. 1 and 2, for example, the business day of the date file 2 does not match the business day of the center data due to a date setting error of the current date means 3, etc. is there.

Therefore, in this case, as a date error on the side of the terminal device 100, the station opening control means 6 instructs the start control means 7 to stop the start, and causes the terminal device 100 to shut down.

As described above, in the above-described embodiment, even if the incorrect current date data is transmitted by the current date means 3 and the terminal device 100 is activated on the incorrect date, the start-time control means 6 sets the center data as the center data. Is performed, and the system is shut down on an incorrect date. Therefore, erroneous operation of the terminal device 100 due to human error or the like can be prevented.

In the above embodiment, the west history time is used as the reference time of the current date means 3. However, the present invention is not limited to this. For example, 1988 is one year of the current date means 3, 1988 → 2 Any reference time may be used as long as the number of years changes continuously every year, such as year.

Further, in the above-described embodiment, the device for setting the date is the terminal device 100. However, this device may be a terminal control device (TC), and in this case, the same effect as in the above-described embodiment can be obtained. .

(Effect of the Invention) According to the date setting means of the present invention described above, a plurality of business days received from the center are stored in the date file, and the date of any of these business days matches the current date of the reference time. The difference between the years of the given date is used as the offset value, and if the date obtained by subtracting the offset value from the current date matches any of multiple business days in the date file, this date is set as the business day date, The following effects are obtained.

That is, even when the center or the communication line goes down and the business day cannot be received from the center, the business day date can be set using the business day in the date file and the current date of the current date means. In addition, even if there is a day when the terminal device has not been activated, an accurate business day date can be set. Further, since the current date is set as the business day date only when the current date matches the business day in the date file, it is possible to prevent the terminal device from starting up on a business day other than the business day. In addition, since the date is set using the offset value, even if there is a change in the era when displaying the business day date in Japanese history, the terminal device does not need to change it at all, and the new era display is accurate Can be performed.
