Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention uses computer technology to capture data representing the time of arrival and departure for personal identification.
This invention relates to a working time aggregation device that automatically uses an IC card.

[Conventional technology]

BACKGROUND ART In factories, offices, etc., the use of time recorders has been widely used as a method for recording when employees come to work and when they leave work, and making it possible to aggregate data regarding working hours.

However, with this time recorder method, the data representing the arrival and departure dates and times of employees, etc. is simply printed and recorded on the time card assigned to each individual, so the data recorded on the time card can be read and used to calculate work hours, etc. In order to do this, it is necessary to read the data printed and recorded on each time card, but this data reading process is difficult to automate and requires a lot of labor and time if done manually. In addition, there was a problem that errors were unavoidable in the data import process, and reliability was poor.

Therefore, in order to deal with the problems of this method using a time recorder, a time card that can store data in a form that can be read by a data reader using magnetic or optical means is used. Personal identification code data set for each individual such as an employee is recorded in the time card, and when this time card is inserted into a designated data reading device (equivalent to a time recorder) at the time of coming to work and leaving work, the code data is recorded. The system reads the information to identify the individual, stores the date and time information at that point in a storage device (memory) such as a magnetic disk, and then uses a data processing device to perform arithmetic processing at the end of the month or other aggregation time, making it easy to tally working hours. A system based on this method was proposed and put into practical use, and examples of this method can be found in JP-A-54-46619 and JP-A-55.
It can be found in the publication No.-124885.

In addition, such conventional technologies include one in which the date and time of arrival and departure are printed on a time card on which personal identification code data is recorded, similar to the conventional time recorder system;
Both are known, though they are not.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the date and time data of the time of arrival and departure, which is necessary for compiling working hours, is all sourced from data stored in the storage device such as the above-mentioned magnetic disk. If an error occurs in the data read from the device, it is difficult to confirm the fact immediately, and with the above-mentioned method that does not print on the time card, there is a risk that all the data will be lost. There was a problem.

An object of the present invention is to immediately check whether or not there is an error in data read from a storage device when calculating working hours, and to enable working hours to be calculated even when data cannot be read. An object of the present invention is to provide a time counting device.

[Means to solve the problem]

The above purpose is to store the date and time data of arrival and departure times using an identification card similar to a time card on which personal identification code data is recorded.
This is achieved by storing the same date and time data on the identification card, and when calculating working hours, collating the data read from both the storage device and the identification card. Ru.

[Effect]

Since the date and time data necessary to tally working hours remains on both the storage device and the personal identification card, it is possible to check for errors by comparing these data, and even if one of the data is lost. , it becomes possible to aggregate working hours.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The working time aggregation device according to the present invention will be described in detail below with reference to illustrated embodiments.

First, an identification card used in place of a time card in an embodiment of the present invention will be explained with reference to FIGS. 1, 2, and 3.

This card is called an IC card, and as is clear from the cross-sectional view in Figure 2, a recess 3 is formed in a part of the card base 2 made of a suitable type of paper or plastic. prescribed in
It accommodates an IC module 4 equipped with an electronic circuit such as an LSI (Large Scale Integrated Circuit), and has contact terminals 5 provided on the outer surface of the IC module 4.As is clear from FIG. Appropriate characters and figures 6 drawn with ink or the like are applied to the surface of the card base 2, and the card base 2 is covered with a protective layer 7 made of a transparent plastic material. Note that the entire IC card is represented by 1.

The electronic circuit using LSI etc. installed in the IC module 4 is, for example, as shown in Fig. 3.
CPU (Central Processing Unit)
40, ROM (Read Only Memory) 41,
It consists of an EEPROM (Electrically Erasable and Programmable ROM) 42, and through each terminal piece 5 ₁ to 5 ₆ of the contact terminal 5,
It is configured to be connectable to a data processing section to be described later.

Therefore, after this IC card 1 is set in a predetermined data processing section and electrical connection is made via the contact terminals 5, data can be exchanged with the data processing section. It is possible to read the identification code data written in the EEPROM 42 and to write the date and time data of the time of coming to work and leaving the work to the EEPROM 42.

Next, FIG. 4 shows an embodiment of the working time aggregation device according to the present invention, in which 10 represents the entire data processing unit corresponding to a time recorder, 11 is an I/O (data input/output device), 12 is a CPU, 13 is RAM (random access memory) for storing transaction data, and 14 is for storing programs.
ROM, 15 is an electronic clock, 16 is an external storage device such as a magnetic disk, 17 is a printing device,
The IC card 1, contact terminals 5, etc. are as explained in FIGS. 1 to 3.

I/O 11 is equipped with a mechanism to accept IC card 1 in the same way as a conventional time recorder, and
The IC card 1 is configured to be connected via the contact terminal 5 when the card 1 is set in a predetermined position, and it is possible to detect that the IC card 1 is set in a predetermined position and to transfer data for this IC card 1. Functions are provided to perform input and output.

The CPU 12, together with the RAM 13 and ROM 14, operates as a computer that processes data and performs calculations.

The electronic clock 15 always generates time data (date and time data) including the current date by counting clock signals and the like.

The storage device 16 functions as a common external memory for all the IC cards 1, and stores date and time data for each IC card individually, such as the date and time of arrival and departure, and It is configured to also store aggregated results and the like.

The printing device 17 functions to print out the total work time results for each individual.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

Now, when employees come to work or leave work,
Assume that the IC card 1 is inserted into a predetermined slot of the I/O 11.

Then, the insertion of this IC card 1 will be
detected by the CPU 12 via O11,
As a result, the CPU 12 starts data communication with the IC card 1. Data communication at this time is possible because the IC card 1 has a built-in microcomputer consisting of a CPU 40, ROM 41, etc.
This can be done in a serial signal input/output format, which allows the terminal piece 5 that constitutes the contact terminal 5 for connection
₁ ~, for example, as shown in Figure 1, 6~8
We are trying to make it possible to reduce the number of items. When the data exchange starts in this way, as shown in FIG.
The identification code data representing the specific individual assigned to the card is read out (S1), the storage device 16 is accessed based on this data, and the validity of the code such as that of an employee is determined (S2).

Next, when the validity of this input code is confirmed, that is, when the judgment result in S2 is YES, the attendance and leaving date and time data at that time is retrieved from the electronic clock 15 (S3), and together with the identification code. It is stored in the storage device 16 (S5). Furthermore, at this time, the attendance and leaving date and time data stored in the storage device 16 is also output to the IC card 1,
The data is written to a predetermined address in the EEPROM 42 (S4). Also, at this time, if it is determined that there is a problem with the validity of IC card 1, that is,
When the result in S2 is NO, the process in S6 is performed and the process ends.

With the above operations, the registration of one time of attendance and leaving information by an employee and the like is completed.

In this way, once the attendance and leaving date and time information has been collected for a predetermined period such as one month, a working time totaling operation is performed.

First, the necessary IC cards 1 are collected on a predetermined counting day, and these cards are set in the I/O 11 one after another. In addition, as the I/O 11 at this time,
It goes without saying that, in addition to the one used for registering when coming to and leaving work, one configured to be convenient for sequentially setting a large number of IC cards 1 one by one may also be used.

The processing at this time is as shown in the flowchart of FIG.
When it is detected that the IC card 1 is set in the EEPROM 42 of the IC card 1, the date and time data recorded for a predetermined period in the EEPROM 42 of the IC card 1 is read out (S11), and the data is processed and the working hours are totaled. Let's do it. Let this tally result be A (S12).

Next, the CPU 12 uses the identification code read from the set IC card 1 to identify the storage device 1.
6 is performed (S13), and the working hours are totaled based on the date and time data stored in the storage device 16. This total result is designated as B (S14).

After that, the CPU 12 collates the tally results A and B (S15), and if they match, the tally result is determined to be correct, and these are stored in the storage device 1 as the final tally result.
(S16), repeats this while determining whether or not it has been completed for all IC cards 1 (S17), and then prints out each IC card in the predetermined order using the printing device 17. (S18, S19).

On the other hand, when the CPU 12 compares the tally results A and B and they show a discrepancy, that is, when the result in S15 is NO, the discrepancy is displayed on an appropriate display (S20), and the discrepancy is displayed. is output as a print (S21).

Therefore, according to this embodiment, the working time tally result is treated as correct only when the data on the IC card 1 and the data on the storage device 16 match, and if they do not match, it is displayed. Also, any discrepancies in the tally results are printed out, so you can always get accurate tally results, and even if the data stored in the storage device 16 is corrupted or contains an error, it will be removed when the working hours are tallied. Since it can be known immediately, based on the aggregate results showing this discrepancy, the data on the IC card 1 side and the storage device can be checked by inquiring the employee or other person to whom the IC card is assigned. It is possible to check which of the data on the 16 side is correct, and it is possible to always obtain the necessary tabulation results reliably.

By the way, in the above embodiment, the EEPROM 42 is used as the data memory in the IC card 1, and as a result, in this embodiment, for example, once the monthly working hours have been tallied, this
The attendance and leaving date and time data stored in the EEPROM 42 can be erased and reused.

Therefore, according to this embodiment, employees, etc.
The IC card assigned to each individual can be used repeatedly each time the counting of working hours is completed, eliminating the disadvantages of conventional time cards such as the need to issue a new card each time the counting is completed. be able to. At this time, the IC card 1
To erase the data stored in EEPROM42,
It goes without saying that this may be performed by the CPU 12 via the I/O 11, or a separate dedicated device may be used.

Note that the present invention is not limited to the embodiments described above, and can be implemented in other embodiments. For example, in the embodiments described above, code list information for determining the validity of the identification code read from the IC card is stored in the storage device 16.
However, it goes without saying that the code list information may be provided in a part of the ROM 14 instead. Further, for example, when a plurality of data processing units 10 corresponding to time recorders are used, the storage device of the central processing unit installed separately may be shared.
It goes without saying that the storage devices of other data processing units may be shared.

Furthermore, the data to be stored in the IC card 1 is not stored sequentially as data on arrival and departure dates, but is stored as data that represents the accumulated working hours totaled by processing the data on arrival and departure each time. Needless to say, the present invention can be implemented using various well-known methods for storage devices, printing devices, data processing methods, etc.

As explained in Fig. 1, the form of the IC card 1 is not limited to a card-like form, but may also be a badge or a tablet-like form.
Needless to say, a storage device such as an IC module may be provided.

In addition, in the above IC card 1, the IC module 4 is equipped with an EEPROM 42, but if repeated use is not required, you can use this instead.
A PROM (programmable ROM) may be used, and in cases where the data storage capacity may be small or where the number of terminal strips 5 ₁ of the contact terminals 5 may be increased, the CPU 40 and ROM 41 may be used. It goes without saying that only PROM or EEPROM may be installed, and these can also be considered as embodiments of the present invention.

〔Effect of the invention〕

According to the present invention, data necessary for totaling working hours is stored in both the storage device on the data processing unit side and the card assigned to each individual such as an employee,
Working hours are now tallied by collating the data stored on both sides.
It eliminates the drawbacks of the conventional technology and is independent of the state of data stored in the storage device on the data processing unit side.
To always reliably obtain a correct working time totaling result and to easily provide a highly reliable working time totaling device at low cost.
