Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time recorder system in which a plurality of time recorder terminals are communicatively connected to a data collector (eg, a personal computer). BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time clock system having a leaving / checking order check function capable of notifying a designation error such as leaving the office.

[0002]

2. Description of the Related Art As a prior art of a time clock system having a leaving / checking order check function, for example, Japanese Utility Model Application Laid-Open No.
There are a time recorder with a leaving / sequence check function disclosed in Japanese Patent Application Laid-Open No. 82766/1990 and a time and attendance management device disclosed in Japanese Patent Application Laid-Open No. 5-35950.

[0003] In the former, time and attendance data composed of an employee's code read from a card and an entry / exit classification specified by a keyboard is temporarily written in a temporary storage memory, and after a predetermined time elapses, the data is stored in the memory. Each time a card is entered while it is stored in a personal file, the last entry / exit category corresponding to the corresponding employee code in the personal file is compared with the entry / exit category specified on the keyboard this time, and the entry / exit category is entered. It is a mechanism to determine whether the order is correct.

[0004] In the latter, the work file / work file is stored in the host computer, and when the attendance data is input at the terminal, it is immediately transmitted to the host computer by communication. After searching for the employee's previous attendance / departure status, comparing it with the designated work / departure category this time, the system returns the result of whether or not the input order is correct to the terminal via communication. ing.

[0005] In a company or a factory having a large number of employees, a plurality of time clock terminals are arranged close to each other at one place to eliminate congestion at the time of commuting or leaving the work. Nevertheless, there is still a situation in which an employee line is formed in front of the time clock terminal when going to work or leaving work.

In such a situation, when checking the input order such as going to work or leaving the work, the employee does not necessarily perform both the entering and leaving work with one and the same time clock terminal. With the former system described in the above technology, the correct order check cannot be performed. In other words, if the attendance data is entered at the left terminal, the data does not exist in the memory of the right terminal. An "error" will result.

The above-mentioned problem does not occur in the latter system described in the above-mentioned prior art, but the latter system has a problem in the speed of the input operation. That is, the time required for a series of operations of inputting the attendance data → sending → checking at the host computer → replying the result → displaying the result is usually about 0.5 to 1.5 seconds. If an employee leaves immediately after the job, there is a risk that the result of the input sequence checked by the host computer will not be transmitted to the employee.

[0008] In addition, if the above-mentioned error display occurs at the same time as the card insertion operation of the employee who comes next, it is said that the employee who entered the card immediately after, instead of the employee who left, is an error. It can be misleading. In short, the employee who left the place immediately after inserting the card is an error, but because of the slow response, it is misunderstood that the employee who inserted the card next is an error.

However, after inserting the card into the employee,
If you give an operation instruction to wait two seconds and check before leaving the time clock terminal, it is obvious that employees will complain and you will be increasingly congested when you go to work or leave work There is also a problem that leads to.

As a means for solving the above problems, the former system is basically used. For example, the data collector transfers the attendance data transmitted from the left time clock terminal to the right time clock terminal. There is a method of giving it. The right time clock terminal stores the attendance data of the left time clock terminal transferred from the data collector in a personal file on its own memory. The attendance data input to the right time clock terminal is also transferred to the left time clock terminal via the data collector. In this way, the time data entered by the employee exists on both the left time clock terminal and the right time clock terminal, so that the correct input order check can be performed, but a new problem arises here. I do.

[0011]

The data collector is connected to dozens of time recorder terminals connected to each other by communication.
Since a total of hundreds or thousands of attendance data are collected each day, the time required for the communication processing is enormous. On the data collector side, various processes related to work management, such as time calculation, must be speeded up from the time data collected,
In some cases, information such as working hours and paid vacations must be created for each individual and transmitted to each time recorder terminal so that employees can check the information on the screen of the time recorder terminal. Alternatively, data collectors (such as personal computers) are not dedicated to employment management,
It may be used to create documents in word processors.

In such a situation, if the data collector processes the attendance data transfer between the time clock terminals, the load on the data collector increases, resulting in a trouble in business.

Accordingly, a technical problem of the present invention is to make it possible for a plurality of time clock terminals to promptly and correctly operate an input order check for clock-in and clock-out.
An object of the present invention is to provide a time recorder system with a leaving / ordering check function which prevents a load on a data collector (a personal computer or the like).

[0014]

Means taken by the present invention to solve the above-mentioned technical problems are as follows.

When the personal identification card is inserted after designating the attendance / departure division such as attendance / exit, at least the attendance / departure division is overwritten in the memory with respect to the attendance data created thereby, while the card is overwritten. Each time is inserted, the previous leaving / leaving section of the individual included in the above memory is extracted, and it is determined whether the currently designated leaving / leaving section conforms to the correct input order such as attending / leaving. A time recorder system in which a plurality of slave time recorder terminals are configured to be connected to a data collection machine serving as a master station.

(1) In each of the above time recorder terminals, when time data is transmitted from another time recorder terminal other than the own device to the above data collector, communication interception means for intercepting the time data, Intercepting data storage means for overwriting at least the leaving / withdrawing section in the personal memory with respect to the data. (Claim 1)

(2) The transmission distance between the other time clock terminal and the own device is at least several cm to several meters, and the transmission distance between the own device and the data collector is at least several m to several hundreds. m. (Claim 2)

A parameter registration means for registering an identification code of another time clock terminal in its own setting parameter file is provided, and communication interception is performed only on the time clock terminals registered in this setting parameter file. (Claim 3)

According to the means described in the above (1), when time data is transmitted from a time clock terminal other than the own device to the data collector, it can be intercepted and taken into the own device. As a result, since the attendance class included in the intercepted time data can be stored in the memory of the own device as the previous attendance class of the individual, the attendance class of the time data input by the employee can be stored. It can be stored in its own memory without exception. As a result, with respect to a plurality of time recorder terminals connected to the data collection device and installed close to each other, even if a card is inserted into any of the time recorder terminals, the attendance class specified at this time is to go to work. It is possible to quickly and accurately determine whether or not a correct input order such as leaving the office is appropriate without imposing a load on the data collector.

According to the means of claim 2 described in the above (2), even when a reception error occurs in the own device at the time of interception of a communication, an instruction to retransmit the attendance data is given to the data collection device as the master station. To make it happen. That is, since the communication noise increases as the transmission distance increases, a data collector located several to several hundred times longer than the transmission distance between adjacent time clock terminals causes more reception errors. It is more likely to occur.

Therefore, when a reception error occurs in the data collector, the time recorder terminal (own device) can correctly receive (intercept) the data, but the reverse is not possible. If this occurs, a reception error will always occur in the data collector. When the transmission quality is good and an interception error does not occur between adjacent time clock terminals, the above-mentioned means (1) is sufficient. However, when it is easily affected by communication noise, the above-mentioned means (2) is used. Shall be.

According to the third aspect of the present invention, when there are three or more time clock terminals in total, a time clock terminal installed close to the communication interception terminal is registered in the parameter registration unit. By obtaining the communication address from the identification code of the time recorder terminal, the communication address can be used in analyzing which time recorder terminal is currently communicating with the data collector. It is needless to say that the identification code itself of the time clock terminal may be used as it is as the communication address.

As described above, the above (1) to
By solving the above technical problem by means of (3),
The problem of the conventional technique can be solved.

In the figure, reference numeral 10 denotes a CPU constituting the center of the control unit, 11 denotes a bus connected to the CPU 10, and a ROM 12 storing various system programs, RAM 13 having a personal master file, etc., transmission driver 14 and reception driver 15, interface circuit 16, internal clock 19
Are connected, and the communication line 3 connected to both the drivers 14 and 15 is connected to the data collector 1 described above.

The interface circuit 16 reads personal information from an ID card or the like inserted into the card insertion slot 6 in addition to the display 5, the keyboard 7 and the key lamp 8 described above. A card input device 6T for reading setting information from the like, a sounding device 9 for generating various messages and alarm sounds, and a DIP switch 18 used for setting a terminal number (communication address) of the own device are connected. I have.

The ROM 12 has a program (working / segment designating means) for designating attending / leaving according to the operation of the keyboard 7, and an ID card for personal identification by designating working / leaving. Is inserted into the card insertion slot 6, the card input device 6T reads the identification code, and the attendance data composed of the identification code and the input / output section and the input time determined by the internal clock 19 are converted into the time code. A program (time data overwriting means) for overwriting an individual file in the RAM 13 for each individual;

A program for judging whether or not there is an incoming / outgoing order check, and a warning display is given on the display 5 when the input order of attendance / exit is inappropriate, and A program (alarm means) for generating an error sound is stored.

Further, in the ROM 12, using the keyboard 7 and the setting card, any one or more identification codes of the other time clock terminals 4A to 4N are registered in the setting parameter file in the RAM 13 of the own device. (Parameter registration means), and when the time data is transmitted from the other time clock terminals 4A to 4N registered in the setting parameter file to the data collector 1, the time data is intercepted (received). A program (communication interception means) for not returning an affirmative / negative response, and a program (interception) for overwriting the intercepted attendance data in the individual master file of the RAM 13 for each individual when there is no reception error. Data storage means).

As described above, the data collection device 1 periodically collects the time data of the time clock terminals 4A to 4N four times a day and files the time data of each person on an individual basis. ing.

FIG. 4 is a communication format of inquiry data transmitted from the data collector 1, FIG. 5 is a communication format of attendance data transmitted from each of the time clock terminals 4A to 4N, and FIG. 6 is a flow of input order of attendance data. This shows an example of a check matrix used when checking (sequence). This check matrix is also stored in the ROM 12.

Next, a processing procedure of interception of time data by the time clock system according to the present invention will be described with reference to a state transition diagram shown in FIG.

From the standby state of step S1, the process proceeds to step S2 by receiving the ENQ shown in FIG. 4, and analyzes the communication address sent from the data collector 1, and if the communication address is its own address. In step S3, the attendance data is read from the data memory 13 in accordance with the data request from the data collector 1.

As a result of the reading in step S3, if there is no attendance data, the process returns to step S1 in the standby state described above, and if there is attendance data, the process proceeds to step S4 to transmit the attendance data to the data collector 1 (personal computer). Then, the process proceeds to step S5 for waiting for a response, and the data collection device 1
If an acknowledgment has been received from
To read the next time data, and if a negative response is received, the process returns to step S4 to repeat the transmission process.

On the other hand, if the communication address is another device address in the second step S2, the flow advances to step S6 to compare this other device address with the other device address registered in the setting parameter file of the RAM 13. If they match, the process proceeds to the next step S7, and if they do not match, the process returns to step S1 in the standby state.

In step S7, the other device (time clock terminal) intercepts the attendance data transmitted to the data collection device 1, and if the reception is normally received, the process proceeds to the next step S8, where a reception error is detected. In this case, the process returns to step S1 in the standby state.

In step S8, the input time of the intercepted time data of the other machine is compared with the input time of the individual's time data stored in the personal master file of the RAM 13, and the input time of the intercepted data is compared. If it is newer, the process proceeds to the next step S9, where the intercepted time data is
The personal master file provided in the AM 13 is overwritten. If the input time of the personal master file is newer, the process returns to the standby state of step S1 and ends.

Next, a description will be given of a processing procedure of a leaving / ordering check by the time clock system according to the present invention with reference to a flowchart shown in FIG.

In the first step S11, any one of the keys 7A, 7B, 7 of the keyboard 7 for going to work, leaving work, going out, and returning.
After pressing C and 7D, proceed to the next step S12 and
When the card is inserted into the insertion slot 6 and the card input device 6T reads the personal identification code, the process proceeds to the next step S13, where R
From the personal master file of the corresponding individual in AM13, the attendance class of the previously stored attendance data is read.

Next, the process proceeds to step S14 to compare the previous read / withdrawal section read out with the current keys 7A to 7D pressed in step S11, and based on the check matrix illustrated in FIG. If the order such as leaving the work is incorrect, the process proceeds to step S15, and a warning is displayed and an error sound is sounded to issue a warning. Then, the process returns to step S11. If the order is proper, the next step is performed. Proceeding to S16, the attendance data including the entry / exit classification, the input time, and the personal identification code is created, and the attendance data is stored in the data memory 1.
After that, the process goes to the next step S17, where the time data is overwritten on the personal master file, and the process returns to the step S11.
