Description

Title: Device for recording and evaluating time and / or operating data

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 recording and evaluating time data of employees, such as presence or working time in a company, or manufacturing times of machines, or for recording and evaluating operating data, such as quantities, dimensions, weights, distances and the like., Or employed employees of a company or machine

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 for the acquisition and evaluation of the time data in accordance with 1A three main elements must be present, namely

1. a registration unit, e.g. the so-called time clock,

2. a storage unit, e.g. the so-called stamp card, and

3. an evaluation unit, e.g. a computer system or a calculator.

With the conventional stamp card, the evaluation is usually done manually, e.g. by typing the data into a calculator. Recently, devices are also known in which electronic document readers read the times stored on the stamp card and evaluate them in an electronic data processing system.

Instead of the conventional stamp card, chip card-based stamp cards are now also available on the market, in which the stamped times are stored in an electronic chip card. In principle, however, these stamp cards based on chip cards do not differ from the known conventional stamp cards, because here too the three main elements of the detection unit, storage unit and evaluation unit are provided at different locations.

The stamp cards have the advantage that each individual stamping process, i.e. e.g. every single COM- or GO stamp is registered and thus each stamp is transparently traceable, but they have the disadvantage that the evaluation is complicated and time-consuming due to the necessary transfer of the data to the evaluation unit.

The initialization and evaluation of the paper or electronic stamp card can be done manually or with the help of devices or a microprocessor. In order to simplify the evaluation, devices are also known which already accumulate the values during the acquisition, for example with the aid of pulse counters, which are integrated in the time recording device and which can also be switched under program control, so that, for example, only times within a certain predetermined amount Time interval are counted. In this way, for example, attendances outside the flextime framework are not counted. These devices in turn have the disadvantage that the individual stamps cannot be traced and therefore incorrect stamps cannot be corrected reliably and reliably.

In order to be able to carry out both an automatic accumulation of the recorded data and a storage of each individual process, systems according to the block diagram of FIG. 1B are currently used, which are characterized by a recording unit with an integrated buffer and computer. This registration unit is connected to a central computer via cable. The recorded data are transmitted to the central computer either immediately after acquisition or at fixed time intervals and stored and evaluated there. This separation into a decentralized registration unit with a buffer and a central storage and evaluation unit has the advantage that any incorrect stamping can be traced. This happens with a very long delay, for example when the employee receives his monthly time evaluation, so that even in these cases there is no longer any correct memory of the actual process. Another disadvantage is that extensive cabling of the company premises is required and the use of such a system is technically very complex. With this system, which requires a BDE network, expensive cabling and complex BDE terminals have to be provided, which is too expensive for smaller companies. Due to lack of mobility is a Evaluation only possible in the central office, so that additional staff is required. In addition, there is no transparency of the individual stamps for the user.

A system is also known from EP-A-0 564 064, in which an identification card with memory and microchip is used, on which application restrictions are stored. The identification card is briefly connected to a stationary, microprocessor-based terminal. The application restrictions are checked and times are temporarily stored on the identification card. The terminal is networked with a host computer on which the actual processing logic is located. A display can be made on the terminal. In this known system, too, it is therefore assumed that the real-time clock is permanently installed in a stationary device, that the processing takes place on a host computer and that a PDA network is required.

From EP-A-0 128 123 a hand-held device for recording, storing and transmitting data is known, in which data are stored which are read with an infrared reader and stored together with the time of recording. Although a microprocessor in the hand-held device is given as an application here, it is nevertheless assumed that the actual evaluation of the recorded data and the assigned times takes place in a separate, stationary host computer, into which the recorded data are transmitted. As a result, the evaluation remains reserved for a separate person and cannot be carried out personally by the user. The evaluation is still carried out in a cumbersome manner by additionally required third parties, so that here too the user lacks transparency about his work. From CH 673 164 A5 a device for recording and evaluating the time and / or operating date with a plurality of portable devices that can be carried, each of which can be assigned to a carrier person by means of an identification code and with at least one recording device, is known. Each terminal has a manual data input device, a buffer for data and a data display and a connection to a recording device, which functions as an interface to a central computer or as a terminal of this central computer. The terminal is connected to the central computer via data lines. Only a buffer is provided in the recording device and no independent intelligence for evaluating the data, this is done exclusively on the central computer. If data are to be recorded at different locations, the recording devices must be connected to one another and also to the central computer. With this system, cabling of the company premises is also a prerequisite for use.

From DE 39 23 524 AI a method for recording and evaluating work, free time and / or absenteeism of employees is known, which should be feasible using an electronic device which corresponds in structure to any computer or computer . Further is not described in this document on the type and structure of the facility. In other words, any portable or permanently installed computer can be used here. This method has the disadvantage that it cannot be proven at which location the data was recorded. If the computer is permanently installed, the data must be temporarily stored at the point of origin, for example by manual writing, and later entered into the computer. If a portable computer is used, the recorded times and other data are also of little evidence, since it has not been proven that these were actually recorded at the intended location. A clear proof of the actual data acquisition at the specified location would also presuppose in this case that a computer with a device described here is permanently installed at each location intended for the data acquisition and the various computers are networked with one another if one and the same person contacts the data from different locations, which must be evaluated together.

Summary is therefore to be determined that all currently used system for the detection and evaluation of time and / or operating data, if they work on an electronic basis, require networking via data lines or at least separate, permanently installed evaluation devices from the detection.

This means that all currently known systems for recording time and operating data are either very complex in terms of evaluation and / or very complex in terms of the technology to be used. For these reasons, all currently commonly used systems for recording time and / or operating data are systems which require the presence of several different devices, at least one device being permanently installed and the data provided for evaluation between the different ones Systems have to be transported back and forth, which is complex and prone to errors. These systems require a locally fixed detection unit and an also locally fixed evaluation unit, whereby only the storage unit can be mobile. Using the example of the acquisition terminal connected to the central computer by cable or by radio, this storage unit is also fixed locally, only the identification card can be used in this case. The acquisition of time and operating data is therefore complex and / or inflexible with the currently known systems. For a large group of users, such as small companies, for example craftsmen, or such large companies, whose employees have to be able to be used flexibly, for example on assembly, in the field, in sales, etc., there are currently no practical solutions that can be used in practice. The same applies if, for example, project or order-related expenses (working hours, production hours, material consumption) or similar things have to be recorded, whereby these expenses can be incurred at very different locations and therefore access to a data entry terminal is not always possible, as is the case, for example, when using the system of a craftsman at the customer's site.

The object of the present invention is therefore to create a device for recording and evaluating time and / or operating data of the type mentioned at the outset, which combines the advantages of the currently known systems and avoids their disadvantages, i.e. , with which the acquisition and evaluation of time and / or operating data can not only be carried out in a simple manner at locations which are at a distance from one another, but also with which an evaluation which can be traced and disclosed to the user is possible at any time.

This object is achieved in a device of the type mentioned by the features specified in claim 1.

With the measures according to the invention, a device is thus created which is technically feasible with little effort and is inexpensive for the user. It is simple and can be used by the user without much learning. The recorded data are always available to the user transparently and in a comparable way as they were recorded. Evaluations can be carried out independently by the user become. The facility can be used both stationary and mobile. According to one embodiment, the data can be transferred to a central office or a central computer. The evaluations can also be carried out both centrally and decentrally. In addition to COMING and GOING, additional information such as project information, cost centers, cost objects, etc. can be entered locally using the keyboard. According to a further exemplary embodiment, such information can be transmitted directly via interfaces of provided devices, such as measuring devices, for example scales, counters, or the like.

Further advantageous embodiments result from the subclaims.

For example, areas of validity are defined in the identification card, in which data is recorded. In addition, information can be stored in the storage unit, which enables the operator to be identified. This identification is expediently carried out by briefly connecting an identification transmitter to the identification card. On the other hand, it is also possible to carry out the identification by entering a key, by means of a code plug, by means of a defined sequence of keyboard entries (password entry) which is carried out via the input unit.

Advantageously, it is also possible that numerical and / or alphanumeric information can be entered on the keyboard, which represent certain people, certain activities, certain cost allocations, certain machines, local conditions and similar characteristics, to which the facility creates summary evaluations and detailed individual evaluations can. If an output printer is connected to the device, summary evaluations or detailed individual evaluations can be printed out on it, in accordance with the programs stored in the program memory and the control codes entered via the keyboard.

If, according to a preferred embodiment of the present invention, an input / output interface is provided, data from external devices, such as machines, measuring devices and the like, can be input in digitized form and this in accordance with the instructions stored in the program memory with the other information available in the device be linked.

Furthermore, data and programs can be transferred from a connected separate computer to the facility via this interface. Correspondingly, data can also be transferred from the device to a connected separate computer. It can be expedient if this transmission takes place at periodic, pre-programmable time intervals and / or when a defined event occurs.

If, according to a further exemplary embodiment of the present invention, control pulses are to be switched via the input / output interface, this can be used to control external devices, such as machines, doors, measuring devices or the like, and to initiate the execution of defined actions.

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

The device or the mobile identification card can expediently be connected via the input / output interface are briefly connected to external devices that are permanently installed at a specific location, so that the user can document his presence or activity at a specific location and at a specific time.

The input / output interface can also be used for time synchronization from an external clock.

Simple "intelligent" and non-networked terminal devices are used for the identification transmitter, such as, for example, those which can be read optically or electromagnetically, such as via barcode readers, infrared readers and the like. According to a further exemplary embodiment of the present invention, the mobile identification card can also be equipped with a sensor, in particular a touch sensor. Semiconductor memories can also be used as the terminal device, in which an identification code that is unique worldwide is permanently programmed. Alternatively, the code can also be set using a program.

Further details of the invention can be found in the following description, in which the invention is described and explained in more detail with reference to the exemplary embodiment illustrated in FIGS. 2 and 3. 2 and 3 each show a block diagram of a device according to a preferred exemplary embodiment of the present invention or an intelligent mobile identification card used in the device according to FIG. 2.

According to FIG. 3, the mobile identification card 11 contained in the device 10 contains a computing unit with processing logic in the form of a microprocessor 12, which is part of an evaluation unit and, as a further part of the evaluation unit, a storage unit 13 with electronic program and data memory in which programs or Data is stored, is assigned. They are in the programs Conditions under which data are accepted, how they are stored and evaluated. The data memory contains information about the person or the identification card 11 from which data is stored, such as, for example, the 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 typed in by means of an input unit 14 with an integrated keyboard or keypad, but can also be transferred via the input / output interface 16 from external devices or a connected separate computer.

Furthermore, the mobile identification card 11 has an interface 15, via which it can communicate with a terminal device 23 in the form of a non-networked identification transmitter. The design of the interface 15 forming part of the identification card 11 depends on the structure of the identification transmitter 23 and preferably represents a reading device.

The mobile identification card also contains a real-time clock 17, in which the date and time are always made available at the time. The real-time clock can optionally be synchronized via radio. The microprocessor 12 fetches the current date and the current time from this real-time clock 17 if required. In addition, the mobile identification card 11 contains a display unit 18 with which the process currently activated in the card and evaluations from the processing of the data are displayed.

The mobile identification card 11 is thus an "intelligent" card which not only unites the storage unit but also the evaluation unit through the microprocessor. Furthermore, a power supply 19 is provided in the identification card 11, which power supply can be permanently connected, but is also mobile for mobile use of the card. As a rule, this will be a battery or an accumulator, which is charged again and again when connected to a power supply unit or by solar elements in the event of light or sunlight.

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

Are the simple (dumb) identification transmitter 23 _'which are provided with a certain coding on activities and / or location of the various jobs in the company and also in jobs outside the farm or in transport, such as in the car. 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 now 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 _x , 23 _a , ... 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 is starting work at this location or for this job. The card 11 retrieves the information from the real-time clock 17 from 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 using a

Identification unit 22 is carried out 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 _r , 23 ₂ or 23- for the project or the task and simultaneously presses on the keyboard the 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 with the identification transmitter 23 _{n of} the old project and simultaneously enter a key combination for INTERRUPT or EXIT 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 subsequently enters the absence reason and absence time manually into the device using the keyboard provided for this purpose, again while simultaneously connecting to an identification transmitter 23 provided for such corrections.

It is possible, but not absolutely necessary, that the cards 11, similar to stamp cards, are deposited centrally at the entrance to the company or in the vicinity of the work place, thus giving the other employees an indication of the presence of the employee.

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 certain key combination while connecting to the identification transmitter 23 _n , which then shows the times be, which were recorded in connection with this identification transmitter 23 _n .

Not only are the individual stamps stored in the card, but evaluations can be made from the card at any time, e.g. are created using accumulated values. Statements such as Which attendance times have so far accrued, which times have been spent in the car or for a certain activity or a specific project, which vacation or illness periods have so far accrued, are possible at any time and can be created by the operator by entering a certain key combination themselves, so they require not the query in a 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 INTERRUPTION of the work while simultaneously connecting to the identification transmitter 23 ₃ . If the work is continued externally, for example, at 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 twins his card 11 with 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 travel time accordingly. In turn, a further identification transmitter 23 _{5 is} installed on the construction site, with which it records the actual presence on the construction site in each case by briefly connecting it to its card 11 and possibly additionally enters a code for the type of activity to be carried out. After completing 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 for this purpose and have the document signed by the customer.

The total attendance times of the employees as well as the share of travel times and actual productive working hours can thus be easily and directly determined from the card 11 without a doubt, but can be transferred via the optional interface 16 to a separate computer and transferred to accounting programs, provided that this is desired.

At defined, fixed or variable time intervals, for example once a month or after completion of the work for a specific project, the data stored in the identification card 11 are to be evaluated and the data memory of the storage unit 13 is to be cleared for new entries. In the simple case, the display unit 18 on which the hours worked in the time segment are displayed is sufficient for this. The individual times and the associated cumulative values can, however, also be printed out on an optionally integrated printer 21 or transmitted to an external device, for example a host computer, via the input / output interface. The host computer can also be permanently connected to a device tableau and in cyclical intervals repeatedly ask the devices whether data are available for them and collect them.

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.

Data and programs can also be transmitted from an external host computer into the identification card 11 via the input / output interface 16. This applies here e.g. for time models, shift models, flextime frames or company calendar with indication of the non-working days.

Another typical operational application is the recording 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, either a separate identification card 11 can be used, or a card 11 can be used for several projects, customers, etc. The employee marks the start of the work on the identification card 11 and notes the associated feature, ie the associated project, order or customer number. After completing the work he creates an evaluation of all times to which this characteristic has been 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 stored once on the identification card 11 and is either entered via the integrated keyboard or the keypad of the input unit 14 or via the input / output interface 16 from an external device or host computer. In addition, 11 subsequent records are entered on the card, these are usually the start and end times at which work was started or ended, as well as an identification code of the processing employee or processing machine whose working or operating times are to be monitored. Depending on the design of the recording and processing program stored in the identification card 11, the

However, input / output interface 16 also transmits digitized counter readings which represent quantities, dimensions, weights or similar values, which are then stored and evaluated on the mobile identification card 11.

Depending on the design of the program stored on the card 11, this information is also evaluated as individual information and / or in a condensed form, taking into account a wide variety of links, and displayed on the display unit 18, printed out to the printer 21 or sent to the input / output interface 16 for further processing transferred to a separate computer. After completion of the evaluation, for example at the end of the project, the data stored on the card 11 are deleted and the card 11 can then be used for other projects. When creating an interim settlement, the operator can choose whether to delete the data or to have it stored on the identification card 11 for a cumulative overall evaluation. The operator decides this depending on the data volume and the available storage space, or it is also a question of an overview of the stored data and the authorization level of the user.

Another typical application can e.g. consists in the user having to document his presence in a certain place at a certain time, e.g. is required for maintenance and operating personnel for technical devices and machines, for groups of people who perform security tasks such as night watchmen, gatekeepers, security services etc. These briefly connect the identification card 11 via the input / output interface 16 to permanently installed external devices. The card 11 queries the identification code of the external device at the terminal and stores the code together with the current time. The operator thus receives proof of presence or activity at a specific time at a specific location and this proof can be shown by means of the program stored in card 11. This facility is also suitable for the verification of certain test procedures in quality control.

The mobile identification card 11 can be implemented without the optional units 21 and 22 when appropriately miniaturized electronic components are used in the outer geometric dimensions of a commercially available pocket calculator and thus achieves the geometric size similar to a stamp card. With correspondingly high numbers, it will only be able to be produced slightly above the production costs of a commercially available calculator. In a manner not shown, the inputs can also be made by an operator into the mobile identification card 11 via a touch sensor.

Data and programs can be transferred from a connected separate computer into the system and vice versa via the input / output interface 16. The transmission can take place at periodic, pre-programmable time intervals and / or when a defined event occurs.

The input / output interface 16 can also be used to apply control pulses which control external devices, such as machines, doors, measuring devices and the like, and cause them to run defined actions.

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

The identification card 11 can also receive time synchronization from an external clock via the input / output interface 16, or a radio clock model is used, the real time clock 17 being synchronized by radio from a central reference timer.

According to an exemplary embodiment for an identification transmitter 23 _n , which is not shown in detail, a semiconductor memory chip, for example a so-called “touch memory” from Dallas Semiconductor, is used. Each of these modules has a fixed number that, according to the manufacturer, exists only once worldwide. During the 2- pin contact with the identification card 11, the code is read and the semiconductor memory chip is briefly supplied with current. For this purpose, the control key of the identification card 11 is pressed briefly while it is connected to the semiconductor memory chip at the same time. In this embodiment, the identification card 11 also has:

a microcomputer with built-in RAM a serial EEPROM data memory for storing at least 100 data records (date, time, code of the

Semiconductor memory chips, status such as coming, going, data retrieved, times to the minute) a hardware clock (radio module) with battery backup

Activity codes

The operation of this embodiment is as follows:

1. The device is switched off in the idle state, it takes only little energy from the battery to operate the hardware clock

2. If the device is connected to the semiconductor memory chip and the "Coming" button is pressed at the same time, the semiconductor memory chip is linked with the date, time and the code for COMING and these values are saved.

3. If the device is connected to the semiconductor memory chip and the GO button is pressed at the same time, the The number of the semiconductor memory chip is linked to the date, time and the code for GO and these values are saved. At the same time, the total time that was reported under this semiconductor memory chip is added up and the total time is totaled over all registered semiconductor memory chips.

4. If the device is connected to the semiconductor memory chip and the control button is pressed, the time that has been accumulated under this semiconductor memory chip is displayed, and if the last COMING was reported, the time that has passed since the last COMING message, if so The last time AGAINST was reported was 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 adjust the clock if no COMING message was last entered, i.e. there are no cancellations or the last time GO was canceled.

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. The data can be output from the identification card 11 to an printer via an interface, 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.

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.
