Description

The present invention relates to a device for recording and evaluating time and / or operating data according to the preamble of claim 1.

For example, such a device is used for detection and evaluating time data from employees, such as Presence or working hours in a company, or by Manufacturing times for machines or for recording and evaluating of operating data, such as quantities, dimensions, weights, distances and the like, or from employees of a company or Machinery.

Time registration devices with a time-controlled printing unit for recording time information in the lines of a stamp card (so-called time clocks) have been known for a long time. These are characterized in that three main elements must be present for the acquisition and evaluation of the time data according to the block diagram of FIG. 1A, namely

1. a registration unit, for example the so-called time clock,

2. a storage unit, for example the so-called stamp card, and

3. an evaluation unit, for example an EDP system or a pocket calculator.

With the conventional stamp card, the evaluation usually manually e.g. by typing the data into one Calculator carried out. Recently, too Known facilities where electronic document readers Read times saved on the stamp card and in a evaluate electronic data processing system.

Instead of the conventional stamp card are now also Chip card-based stamp cards available on the market, where the stamped times are in an electronic Chip card can be saved. These stamp cards on However, chip card bases differ in principle not from the known conventional stamp cards because the three main elements of the registration unit, Storage unit and evaluation unit at different locations are provided.

The stamp cards have the advantage that each one Stamping process, i.e. e.g. every single COMES or GOES stamp is registered and therefore every stamp is transparent, but they have that Disadvantage that the evaluation by the necessary transfer the data in the evaluation unit cumbersome and expensive becomes.

The initialization and evaluation of the paper or Electronic stamp card can be done manually or with the help devices or a microprocessor.

To simplify the evaluation, there are also facilities known that a cumulation of the Make values, e.g. with the help of pulse counters, which in Time recording device are integrated and that too can be switched under program control, so that e.g. just Times within a certain predetermined time interval be counted. In this way e.g. Attendances not counted outside of flexitime. These devices again have the disadvantage that the individual stamps are not traceable and therefore incorrect cancellations are not can be corrected safely and reliably.

In order to have both an automatic accumulation of the recorded data also save each individual process systems are currently being developed according to the block diagram of Figure 1B applied by using a registration unit Mark the integrated clipboard and calculator. This Registration unit is wired to a central computer connected. The captured data are either immediately after recording or at fixed time intervals at the central Transfer the computer and save and evaluate it there. This Separation into a decentralized registration unit with Buffer and a central storage and Evaluation unit has the advantage that possible False cancellations are traceable. This happens with a lot long delay, e.g. then when the employee is his receives monthly time evaluation, so that even in these cases not necessarily a correct memory of the actual process exists. Another disadvantage is that extensive wiring of the Company premises is required and the use of a such a system is technically very complex. With this System that requires a PDA network made expensive wiring and elaborate BDE terminals are provided, what for smaller companies is too expensive. Due to lack of mobility is a Evaluation only possible in the control center, so that additional Personnel is required. In addition, there is no transparency given individual stamps for the user.

FR-A-2,689,275 discloses a device having the features of the preamble of claim 1.

A system is also known from EP-A-0 564 064 an identification card with memory and microchip is used on which application restrictions are saved will. The identification card is briefly marked with a stationary terminal based on a microprocessor connected. The application restrictions are checked and possibly times on the identification card cached. The terminal is with a host computer networked on which the actual processing logic is based located. A display can be made on the terminal. Also in this known system it is therefore assumed that the Real-time clock is permanently installed in a stationary device, the processing is done on a host computer and a BDE network must be available.

EP-A-0 128 123 describes a handheld device for recording, Storage and transmission of data known in the data are saved, which are read with an infrared reader and saved along with the time of recording will. Although here a microprocessor in the handheld device as Application is specified, it is nevertheless assumed that the actual evaluation of the recorded data and the assigned times in a separate, stationary installed host computer takes place in which the recorded data be transmitted. As a result, the evaluation remains reserved to a separate person and cannot be accepted by the Be made personally. The evaluation takes place continue to be cumbersome by additional required third parties, so that the user there is no transparency about his work.

CH 673 164 A5 is a device for recording and Evaluation of time and / or operating date with a number portable terminal devices, each of which by means of a Identification code is to be assigned to a carrier and with known at least one detection device. Each points Terminal a manual data entry device, a Buffer for data and a data display and one Connection to a data acquisition device, which acts as an interface a central computer or as a terminal of this central Calculator acts. The terminal is with the central computer connected via data lines. There is only one in the registration device Buffer provided and no independent Intelligence to evaluate the data, this is done exclusively on the central computer. If data is available different locations are to be recorded, the Registration devices with each other and also with the central one Computer connected. So this is one with this system too Cabling of the company premises is a prerequisite for one Commitment.

DE 39 23 524 A1 describes a method for detecting and Evaluation of work, free time and / or absenteeism from Employees known that using a electronic device, which in its construction everyone corresponds to any computer or computer, can be carried out should. There is more in this document on type and structure the facility not described. In other words, it can here any portable or permanently installed Computers. This method has the disadvantage that there is no evidence of where the data is located were recorded. If the computer is installed permanently, so the data must be at the place of origin e.g. by manual Recordings cached and later in the computer be entered. If a portable computer is used, so only have the recorded times and other dates low evidential value, since it has not been proven that this were actually recorded at the intended location. A clear evidence of the actual data acquisition on the In this case, the specified location would also require that a computer with each location intended for data collection a device described here is permanently installed and the different computers are networked together when one and the same person in different places data which should be evaluated together.

In summary, it can therefore be said that all are currently Common system for recording and evaluating time and / or Operational data if it is electronic work, networking via data lines or at least fixed, separate from the detection Require evaluation devices.

This means that all currently known systems for Recording time and operating data is either very time-consuming regarding the evaluation and / or very complex regarding the technology to be used. It is for these reasons in all currently used systems Acquisition of time and / or operating data around systems which the presence of several different devices require, with at least one device stationary is installed and the data intended for evaluation transported back and forth between the different systems have to be what is elaborate and prone to errors is. These systems require a fixed one Registration unit and also a locally fixed one Evaluation unit, only the storage unit being mobile can be. Using the example of the on the central computer via cable or This is a recording terminal connected by radio Storage unit also fixed locally, only that In this case, the identification card can be used as a mobile device.

The acquisition of time and operating data is therefore with the currently known systems complex and / or inflexible. For a large group of users, such as small businesses, e.g. Craftsmen, or such large companies, whose employees e.g. flexible on assembly, in the field, in sales, etc. there must currently be none in practice reasonably usable solutions. The same applies if e.g. project or order related expenses (Working hours, production hours, material consumption) or Similar things need to be covered, taking these expenses can occur at very different locations and therefore access to a data entry terminal is not always possible is possible, as e.g. when using a craftsman Local customers.

The object of the present invention is therefore a Device for recording and evaluating time and / or To create operating data of the type mentioned that the Advantages of the currently known systems combined and their Avoids disadvantages, i.e. with which the detection and Evaluation of time and / or operating data not only in can be carried out in a simple manner at distant locations but with one for the user comprehensible and reportable evaluation at any time is possible.

This task is carried out in a facility of the type mentioned solved by the features specified in claim 1.

With the measures according to the invention is thus a device created that can be realized technically with little effort and is inexpensive for the user. It is simple and without large learning effort applicable to the user. The data collected are always transparent and comparable to the user Way in which they were received. Evaluations can be carried out independently by the user will. The facility is both stationary and mobile applicable. The data can be according to one embodiment be transferred to a central office or a central computer. The evaluations can also be done both centrally and decentrally be made. In addition to COMING and GO additional information, such as project information, Cost centers, cost units etc. decentrally via keyboard can be entered. According to a further embodiment such information can be accessed directly via interfaces of provided devices, such as measuring devices, e.g. scales, Counter, or the like to be transferable.

Further advantageous configurations result from the Subclaims.

For example, in the identification card Scope in which data is recorded will. Information can also be stored in the storage unit be filed, which is an identification of the operator enable. This identification is expediently carried out by briefly connecting an identification transmitter with the identification card. On the other hand, it is also possible identification by entering a key, through a code plug, through a via the input unit the specified sequence of keystrokes (Password entry).

It is also expediently possible to use the keyboard Numeric and / or alphanumeric information entered can be what certain people, certain Activities, certain cost allocations, certain machines, represent local conditions and similar characteristics, to which the institution assigned summary evaluations and can create detailed individual evaluations.

If an output printer is connected to the device, you can on this summary evaluations or detailed Individual evaluations are printed out, and accordingly the programs stored in the program memory and the over Keyboard entered control codes.

Is present according to a preferred embodiment In addition to the interface, the invention provides an input / output interface Data from external devices such as machines, measuring devices and Like. Entered in digitized form and this according to the instructions stored in the program memory with the rest of the information available in the facility be linked.

Furthermore, data and Programs from a connected separate computer in the Facility to be transferred. In a corresponding way also vice versa from the facility to a connected one separate computer data are transmitted. It can be useful if this transmission in periodic preprogrammable intervals and / or when a defined event takes place.

According to a further exemplary embodiment, they are present Invention via the input / output interface control pulses switch with this external devices, such as. Controlled machines, doors, measuring devices or the like and for Defined actions can be initiated.

The storage unit for programs and Data is temporarily removed from the system so that it loaded and queried separately with programs and / or data can be.

The device or the mobile can expediently Identification card via the input / output interface can be connected to external devices for a short time a certain place are permanently installed, so that the User his presence or activity on a particular Can document location and at a specific time.

The input / output interface can also be used for Time synchronization can be used by an external clock.

Simple "intelligent" and uses non-networked terminals such as those that are optical or electromagnetic, such as via Barcode readers, infrared readers and the like can be read. According to a further exemplary embodiment The present invention with the mobile identification card a sensor, especially a touch sensor. Semiconductor memories can also be used as the terminal device in which a globally unique Identification code is permanently programmed. Alternatively, you can the code can also be set by program.

Further details of the invention are as follows Description can be found in which the invention using the in Figures 2 and 3 illustrated embodiment is described and explained. Figures 2 and 3 each a block diagram of a device according to one preferred embodiment of the present invention or one used in the device according to Figure 2 intelligent mobile identification card.

According to Figure 3 contains the contained in the device 10 mobile identification card 11 with a computing unit Processing logic in the form of a microprocessor 12, the part an evaluation unit and that as a further part of the Evaluation unit a memory unit 13 with electronic Program and data storage in which programs or data be saved, is assigned. They are in the programs Conditions under which data is accepted how these are stored and evaluated. Of the Data storage contains information about the person or Identification card 11, from which data is stored, such as e.g. Personnel number and / or name of the employee, Device number, machine number, cost center, cost unit, Order number, project number and / or similar information. This Information is entered using an input unit 14 integrated keyboard or keypad can be typed in but also via the input / output interface 16 from external Devices or a connected separate computer be dubbed.

Furthermore, the mobile identification card 11 has one Interface 15, via which it is in the form of a terminal 23 a non-networked identification transmitter can communicate. The formation of a component of the identification card 11 forming interface 15 depends on the structure of the Identification transmitter 23 and preferably provides one Reading device.

The mobile identification card also includes one Real-time clock 17, in the date and time always up to date Will be provided. The real-time clock can optionally via Radio synchronized. From this real time clock 17 picks up the microprocessor 12 if necessary the current date and the current time. In addition, the mobile contains Identification card 11 a display unit 18 with which the Process and evaluations currently activated on the card the processing of the data are displayed.

The mobile identification card 11 is thus one "intelligent" card that is not just the storage unit but also the evaluation unit in by the microprocessor unites.

Furthermore, one is in the identification card 11 Power supply 19 is provided, which is stationary can be connected for mobile use of the card but is also mobile. As a rule, this will be one Battery or an accumulator, which in stationary Connection to a power supply again or again Solar elements charged when exposed to light or sunlight becomes.

A common operational application will be, for example, as follows: reference being made to FIG. 2:

Are located at the different jobs in the company and also in jobs outside the farm or in transport, such as in the car, the simple (dumb) identification transmitter _23a which activity and / or location are provided with respect to a particular encoding. These can be very simple passive elements, for example a simple coding plug or a semiconductor memory in which a specific coding is entered. In this latter case, the interface 15 of the card 11 has a component that establishes the electrical connection to the semiconductor memory. However, the identification transmitter 23 can also contain a character string, which is read, for example, via a barcode, magnetic code or infrared reading device of the interface 15 of the card 11 and can also contain further information, for example to identify the activity currently to be carried out. The coding can either be fixed or can be freely modified.

If the employee comes into operation, he briefly connects his identification card 11 to one of the permanently installed, but non-networked and coded simple identification transmitters 23 ₁ , 23 ₂ , ... 23 _n and simultaneously presses on the keyboard or the keypad 14 a corresponding key, which indicates and stores that he is now present and starts work at this location or for this job. The card 11 fetches the information from the real-time clock 17 of the date and time and stores it in connection with the code for COMING and the code of the identification transmitter 23 _n in the memory unit 13 after prior checking as to whether certain requirements are met, i.e. the stamping, for example takes place in the specified flextime frame or in the specified shift sequence, the optional identity check has been successfully completed or a sensible sequence of operations has been followed, e.g. because GOING stamping requires previous COMING stamping. Such tests are carried out using the stored program and additional test criteria that can be entered, such as working time models and the like. A similar procedure is followed when the employee GOES. The optional identity check with the aid of an identification unit 22 takes place either by entering a password or identification code or by pulling an identity card (chip card, bar code card or the like) into a device which is connected via the input / output interface 16.

If the employee takes up work for a specific project or a specific task at his workplace, he briefly connects his card 11 to the identification transmitter 23 ₁ , 23 ₂ or 23 ₃ for the project or the task and simultaneously presses on the keyboard Key combination for COMING or RECORDING THE ACTIVITY. If he ends the work for this project and starts a new task, he registers for the new project and at the same time sets the activity for the old project to INTERRUPT, or he explicitly logs out of the old project by using his card 11 connects to the identification transmitter 23 _{n of} the old project and at the same time enters a key combination for INTERRUPTION or TERMINATION of the old project.

If the employee changes his place of work, for example if he goes to a construction site or visits a customer with the motor vehicle, he takes his mobile identification card 11 with him. At his temporary work place, the employee can make an entry with his card 11 in connection with the identification transmitter 23 ₄ installed there, in the same way as if he were in the company at his regular work place.

If the employee is absent for unforeseen reasons, e.g. in the event of illness, he or a correspondingly authorized employee manually enters the reason for absence and absence time into the device using the keyboard provided for this purpose, again while simultaneously connecting to an identification transmitter 23 _n provided for such corrections.

It is possible, but not essential, that the Cards 11 similar to stamp cards centrally at the entrance of the Company or near the workplace and thus a note to the other employees about the Presence of the employee is given.

As with traditional stamp cards, the individual stamps can be displayed transparently with the card, however, cumulative values can also be displayed, e.g. how many hours the employee was present at the moment about his flextime target or how many hours have already been worked for a specific task or project. This is done, for example, by entering the relevant project or instead by pressing a specific key combination while simultaneously connecting to the identification transmitter 23 _n , which then shows the times which were recorded in connection with this identification transmitter 23 _n .

Not only the individual stamps are on the card saved, but it can be removed from the map at any time Evaluations e.g. created about accumulation values will. Statements such as what attendance times so far what times are incurred in the car or for a specific one Activity or a specific project has been spent what periods of vacation or illness have so far accrued, are possible at any time and can be done by the operator by entering a certain key combination itself created, do not need to be consulted in one central department.

Another typical application is, for example, answering the question of which employees, departments, machines, etc., and how long were involved in processing an order. For this purpose, a mobile card 11 is given, for example, to a production order that moves through the company and / or also to external locations. An identification transmitter 23 ₃ , each with a coding, is located at each production site. At the start of work at the relevant production site, the employee briefly connects the card 11 to the identification transmitter 23 ₃ and at the same time presses the key combination for BEGIN the work. When he has finished the work, he presses the key combination for END or INTERRUPT the work while connecting to the identification transmitter 23 ₃ . If the work is continued externally, for example, with a subcontractor, the subcontractor only needs an additional identification transmitter 23 ₃ , and he receives the card 11 for the order together with the material to be processed. This enables him to prove the period in which he was working on the order, and thus has a clear basis for billing.

Another typical application is the activity of a craftsman. If he comes to work in the morning, he connects his card 11 to the identification transmitter 23 _n and presses the key combination for COME. If he ends his work in the evening, he does so accordingly with the key combination for GO. If he drives the car to the construction site, he has an identification transmitter 23 ₄ in the car, with which he records the journey time accordingly. On the construction site, in turn, a further identification transmitter 23 _{5 is} installed, with which it records the actual presence on the construction site by briefly connecting it to its card 11 and possibly also enters a code for the type of activity to be carried out. After completion of the work at the customer, he can show him directly with his card 11 how long he has been working for this customer and, if necessary, print out the individual times and the accumulation values with the optional printer and have the document signed by the customer.

The total attendance times of the employees as well as the Proportion of travel times and actual productive performance Working hours can thus be skipped directly in a simple manner the map 11 can be determined without a doubt, but can via the optional interface 16 to a separate computer are transferred and transferred to accounting programs there if so desired.

At defined, fixed or variable time intervals, e.g. once a month or after completing work for a specific project are those in the identification card 11 evaluate stored data and the data storage of Storage unit 13 is to be cleared for new entries. Therefor in the simple case, the display unit 18 is sufficient on the the hours worked in the time period are displayed. The individual times and the associated cumulative values can, however, also on an optionally integrated printer 21 printed out or via the input / output interface external device, e.g. a host computer will be transferred. Of the Host computers can also permanently use a device panel be connected and in cyclical intervals again and again in the Ask devices if there is data available for them and this pick up.

This requires that the input / output interface 16 be connected to the host computer. If the data are transferred correctly to the host computer or if an appropriate input code on the keyboard of the input unit 14 confirms that the processing has taken place and the data recorded in the identification card are no longer required, they are deleted from it. As additional security against unauthorized deletion, the simultaneous connection to a special identification transmitter 23 _{n can be} prescribed.

Via the input / output interface 16, data and Programs from an external host computer in the Identification card 11 are transmitted. This applies here e.g. for time models, shift models, flextime frames or Company calendar with indication of the days off.

Another typical operational application is capture of project, order or customer-related activities and / or the working hours required for this. For each Project, for each order or for each customer can either a separate identification card 11 can be used, or but it becomes a card 11 for multiple projects, customers, etc. used. The employee marks on the Identification card 11 the start of the work and noted the associated characteristic, i.e. the associated project, Order or customer number. After completing the work he creates an evaluation of all times that this Characteristic was assigned.

This can e.g. look like this:

The identification card receives certain header information such as Customer number or order number or project number and the associated designation. This header information is unique the identification card 11 is filed and is either over the integrated keyboard or the keypad of the Input unit 14 or via the input / output interface 16 entered from an external device or host computer. In addition, 11 subsequent records are entered on the map, these are usually start and end times, at which one Work was started or finished, as well as a Identification code of the processing employee or the Processing machine, its working or operating times should be monitored. Depending on the design of the Identification card 11 stored recording and Processing program can via the Input / output interface 16, however, also digitized Meter readings are transmitted, what quantities, dimensions, weights or represent similar values, which are then on the mobile Identification card 11 can be saved and evaluated.

This information is also, depending on the design of the Card 11 stored program as individual information and / or in condensed form taking into account different links evaluated and on the Display unit 18 displayed, the printer 21 printed or via the input / output interface 16 for further Transfer processing to a separate computer. After Completion of the evaluation, e.g. at the end of the project, data stored on card 11 is deleted and card 11 can then be used for other projects.

When creating an interim statement, the operator can choose whether to delete the data or for one cumulative overall evaluation on the identification card 11 saved. The operator decides this in Dependence on the data volume and the available Storage space, or it is also a question of overview the stored data and the authorization level of the User.

Another typical application can e.g. consist in that the user to be present in a certain place a certain time, as e.g. at Maintenance and operating personnel for technical devices and Machines is required for groups of people who Perform security tasks such as night watchmen, gatekeepers, Security services etc. These connect the identification card 11 via the input / output interface 16 for a short time installed external devices. Card 11 asks Identification code of the external device at the terminal from and stores the code along with the current time. Of the This gives the operator proof of presence or Activity at a certain time in a certain place and this evidence can be obtained by means of the card 11 stored program can be shown. Also for that Proof of certain examination procedures in the This facility is suitable for quality control.

The mobile identification card 11 can be without optional units 21 and 22 when used accordingly miniaturized electronic components in the outer geometric dimensions of a commercially available Realize pocket calculator and thus achieves that geometric size similar to a stamp card. she is only slightly above if the number of items is high the manufacturing cost of a commercially available calculator to be manufactured.

In a manner not shown, the inputs from one Operator in the mobile identification card 11 also via a Touch sensor done.

Via the input / output interface 16, data and Programs from a connected separate computer in the System and vice versa. The Transmission at periodic, pre-programmable intervals and / or when a defined event occurs.

The input / output interface 16 can also be used to connect Control pulses are used, such as external devices Control machines, doors, measuring devices and the like Initiate the execution of defined actions.

The one provided in the mobile identification card 11 Storage unit 13 with the program memory and data memory can be temporarily removed from the mobile identification card and then loaded separately with programs and / or data or be queried. In the mobile identification card 11 provision is also made for the stored information even in the event of a temporary failure the power supply 19 are retained.

Via the input / output interface 16, the Identification card 11 also a time synchronization of an external clock, or it becomes a radio clock model used, the real time clock 17 from a central Reference timer is synchronized by radio.

• if last was AGAINST, the total time that was accumulated under this semiconductor memory chip.

5. If the control button is pressed briefly twice in succession without being connected to a semiconductor memory chip at the same time, the date, time and the total accumulated time are displayed. If the control button is pressed again, the last COMING or GOING time is displayed with the associated semiconductor memory chip. By repeatedly pressing the control button, the times can be viewed looking backwards.

6. The hardware clock is set directly via radio (radio clock) or via the serial interface via a PC. It should only be possible to set the clock if no COMING message was last entered, ie there were no cancellations or last GO was stamped.

7. The stored data records are read out on a PC. Data records read out are given a corresponding code. Reading is activated by pressing the COMMENU and control buttons simultaneously.

8. The data can be output from the identification card 11 via an interface to a printer, including printing out the cumulative values per semiconductor memory chip and the cumulative values as a whole. Printing is activated by simultaneously pressing the GO and control buttons.

9. The data (all stamp data as well as all accumulated values) in the identification card should be deleted by pressing all 3 keys simultaneously. These buttons have been placed so that accidental deletion is unlikely. Optionally, the deletion can only be carried out if the connection to a special identification transmitter 23 _{n is} established at the same time, so that deletion can only be carried out, for example, by specially authorized employees. Another option is that the deletion can only be carried out by a PC program via the input / output interface 16.
