Abstract

Apparatus for recording data related to the vehicle and to the driver. The data related to the vehicle are transmitted by an appropriate transmitter and the values are reported by means of a RAM memory into a data cassette (3) by an electronic microprocessor system (MC, RAM, ROM). The data related to the driver, particularly the informations concerning the time groups corresponding to the driving duration planning, are also recorded into the data cassette (3) by the setting of graduated switches (8, 9). But these informations are also recorded on a data card (7) which is also plugged in. Another graduated switch (10) enables to visualize the data contained in the data card (7) on a digital display (11) which may be alternatively used to display the time and date by means of a functional watch unit (UD). It is possible to use a mobile computing instrument (15) in order to archive, during road traffic checks, the content of the data card (7).

1 data acquisition device for vehicles

The invention relates to a data acquisition device for acquiring vehicle and driver-related data in a motor vehicle.

For example, a device is described in ÜS-A 4 188 618, in which the device of several sensors, for example for the speed, for the speed and for the

_ _Q IELD fuel, detected values with arbitrarily be input with the aid of certain switches Verarbeitungs¬ information in a microprocessor in a certain way processed and then stored in a data cartridge wer¬ containing the inter alia, a semiconductor memory.

_ - ^• The data cartridge may be the data collection device taken and entered directly into a reader in a computer wer¬ to, or the data may also be using a trag¬ cash evaluator at different locations can be read and be storable and dispensable.

20th

The known device essentially detects vehicle-related

Data that is removed from the device after some time, for example a week, by transferring the contents of the cassette to the computer, storing it or printing it in an archivable form.

However, when using such a device, it is also important not only to record the vehicle-related data, but also driver-related data, for example the time group data, which result from the EC Working Time Regulation for drivers. 1 In this context, it is also known from DE-Bl 1276 951 to additionally label two 5 driver-related diagram disks for a tachograph in addition to the main diagram disk, which records the vehicle-related data, such as speed and distance registrations the vehicle-related diagram disc are arranged such that the vehicle-related diagram disc contains only this data, while the two driver-related diagram discs only carry the working time data. When evaluating the

_ _Q thus recorded vehicle and fahrerbezoge¬ nen data results in the difficulty of the assignment of the data recorded on the driver-related disks, the data that has been registered on the vehicle-related Frisbee ,, because naturally every three slices

• _j -g can be evaluated separately. In particular, it is disadvantageous that with this form of recording it is not possible to assign the vehicle-related data to a specific driver without further ado. ^"It is also not possible with this form of recording to

Compress 2 _Q tεn in some form, as well

Recordings, for example beyond a day, cannot be made. In addition, the evaluation of the driver-related data in relation to violations of the working time regulation is of course a relatively high

25 hen effort in the evaluation device entails.

In principle, it would be conceivable to also record driver-related data with a device of the first-mentioned type in accordance with OS-A 4 188 618, which would then be readily related to the vehicle-related data. For the drivers, however, this form of recording would have the major disadvantage that it would only take a detour

O Pi could get knowledge of their own data via the computer, since these are only contained in the cassette and can only be made visible to the driver after evaluation by the computer.

In order to solve the problems associated with this, in particular to improve the acceptance of such a data acquisition device by the drivers of the motor vehicles, it is expedient to assign the driver a separate data carrier which can serve him as evidence of his own work and whose data he can make visible to himself. The police can also make the data recorded here more easily recognizable during occasional road traffic checks.

The invention is based on a data acquisition device for acquiring vehicle and driver-related data in a motor vehicle, consisting of a microprocessor system with live memory and system memory, at least part of the live memory being arranged in a plug-in cassette which can be removed for evaluation. and is characterized in that the device is equipped, in addition to the cassette, with an additional insertion opening for a driver's pass in the form of a data card, in such a way that the system memory controls data transfers between the live memory and the data card.

When using an additional data card according to the invention for the data cassette, the data can be transmitted by the driver himself by actuating the corresponding operating elements to a digital display provided for this purpose in the recording device, so that the driver himself has control over which working hours he has ¬ were drawn and which violations of the working time schedule are to blame for him during the past period. Like the known tachographs, the recording device according to the invention is equipped with time group switches which allow the driver to inform the device of the service he has just performed, so that the time group or type of work in life is also stored on the driver-related data card can be saved. So that the data can be recorded in the correct time and date-related form, the device is provided with a clock and date module which allows the time-related recording of the time groups.

In addition to the time group switches, a further multi-step switch is provided, with the aid of which the information can be called up from the data card onto the display.

Since there are always difficulties in accommodating such devices in the dashboard of the motor vehicle, it makes sense to display the necessary display of the dynamic, vehicle-related data with the aid of analog display media arranged separately in the dashboard.

The data card itself can be one of the known magnetic cards. However, it can also be a data card in which a semiconductor module with a correspondingly large memory is welded in. The data card itself is locked in the recording device as long as no other setting of the time group switches is made, in particular as long as no switchover to another driver is made.

The basic principle is that the data card should only contain information recorded twice, ie information that is recorded both in the cassette and on the card. For road traffic control can either use the internal display of the detection device. If there are violations, it is sufficient if a small, mobile reading device is available which is only able to read the data from the data card without any evaluations or the like being carried out. This mobile recording device can be provided with a display medium and / or with a corresponding printer.

The invention will now be explained in more detail with reference to the accompanying drawings. In these drawings shows

FIG. 1 is a front view of the data acquisition device,

FIG. 2 is a schematic circuit diagram of the electrical components of the detection device,

FIG. 3 shows the evaluation device for the data cards,

FIG. 4 shows the evaluation device for the data cartridge.

FIG. 1 shows a front view of the data acquisition device 1. The device has an insertion opening 2, into which a data cartridge 3 can be inserted. This data cassette 3 is used in a manner specified by a system memory to record both vehicle-related and driver-related data. The cassette is secured by a lock 4, so that only authorized persons can use a key 5, see FIG. 2, the cassette 3 can be removed. On the front of the device 1 there is also a plug-in opening 6 for a driver, in the form of a data card 7, which can be inserted into the plug-in opening 6 and is held in this plug-in opening _ will, as will be described in detail later. The device is also provided with two time group or work type switches 8 and 9, which are designed as rotary switches and which allow a specific 5 work time group to be set for each driver, such as work time at the wheel sonstige, other work time 0 and rest time J—. , For each driver, the corresponding working time group can be set by setting the step switches 8 and 9 accordingly. By a mechanical

2.0 Locking is achieved so that both drivers can not simultaneously adjust to work at the wheel. Another multi-stage switch 10 has a larger number of adjustment options. It is used not only to enter vehicle-related data, such as "driving with a trailer", "driving without a trailer", but it is also used to store the data recorded on the data card 7 one after the other Visualize display medium 11, which allows eight digits to be displayed simultaneously. In normal operation, this display medium becomes the time and

2 _Q display the date. Only if the driver wants to make the data on the data card 7 visible, will he correspondingly call up the various data groups from the data card 7 by setting the multi-stage switch 10 accordingly.

As far as the electronic components are concerned, the data acquisition device 1 consists of a microprocessor MC, which also has a live memory RAM, and a system memory ROM, which can also be in the form of a so-called EPROM. The data of the live memory RAM are backed up by a battery B. Another live memory RAM is arranged in the data cartridge 3. The data is also backed up here by a battery B_. In addition, the data acquisition device has a UD block that records the time and delivers the date, via external switches US, which are accessible from the recess 2 for the oil cassette 3, the time and the date can be adjusted as soon as there is no data cassette 3 in the recess 2. A driver module AT serves to multiplex the display 11 and to amplify the data to be displayed which is output by the microprocessor MC.

The various modules are connected to one another via an address bus A and a data bus D. They are also connected to three interfaces SE, SA and SG. The interface SS is used to scan various status inputs, including switches 3, 9 and 10, in order to determine which of these switches are closed in which position. The interface SG is used to connect the dynamic sensors, such as a pulse generator for the speed 12, a pulse generator 13 for the speed and a pulse generator 14 for example for fuel consumption. Via this interface, the transmitters 12 to 14 are queried sequentially by the microprocessor MC in order to determine whether there are any pulses to be processed.

Various external output components are supplied with information for the SA interface. For example, a stepper motor MS is driven step by step in order to set an analog display AV for the speed, ie in order to set the pointer Z step by step to the speed driven in accordance with the number of pulses "transmitted via the stepper motor MS." Another output The interface SA is connected to a magnetic head MK, which records and reads the data on the data card 7. For this purpose, the magnetic head MK must be driven back and forth by a motor. if it is supplied with power via the interface outputs SA, it is not particularly shown for the sake of clarity, but an electromagnet EM is also supplied with power via the interface outputs, for example, which has the task of actuating a latch 22 for the data card conditions so that the data card is held in the device under certain circumstances. In addition, the ignition of the vehicle can also be blocked by an electromagnet EM, for example if no data card 7 is inserted into the slot 6, so that the vehicle is not ready to drive if the driver has not correctly inserted his data card. The boundary line of the data acquisition device 1 is drawn in dashed lines at the location of the interface arrangements SE, SA and SG, which is intended to make it clear that the sensors and receivers can both be arranged in the device itself, such as, for. B. 8, 9, 10, EM, MK but also externally, such as. B. 12, 13, 14 and MS.

An NT power supply unit supplies the various units with power. The type of data that is recorded by the data acquisition device 1 can be seen from the following tabular overview, on the basis of which the function of the device is to be described.

The table shows on the left the data that are recorded in the data cartridge 3 and on the right the data that are reproduced on the data cards 7 for driver I and driver II.

As for the vehicle-related data, the data that appear under a) in the table on the left are first written into the live memory RAM of the microprocessor MC, that is, above all, the device no., The vehicle no Personal No. the authorized driver, certain vehicle parameters etc. These data are written into the living memory RAM of the microprocessor MC from a computer via a special cassette. This is information that does not change unless organizational changes are made in the vehicle fleet concerned.

In the live memory RAM of the cassette 3, on the other hand, the data b-e are written down, which are constantly created during the journey. For example, in the left table at b) the recording of the data relating to the working time groups of the drivers begins. As soon as driver I, for example, inserts his data card 7 and sets the tap changer 8, the module UD determines the time and date and writes this information into the data cassette 3.

In addition there is the personnel number. of the corresponding driver.

This number is taken from the driver's data card 7 and is compared with the authorized driver names registered under a). If there is no match, card 7 is rejected. The vehicle can then also not be started because the system program ROM links the information "card 7 inserted" with the release of the engine starting. As soon as the driver switches to another time group, for example to a break, the end is registered for the driving type of work and at the same time the start for the pause type of work. This same information is also written to the data card 7 via the magnetic head MK, controlled by the microprocessor MC. The storage space in the data cassette for the information according to b) is kept in such a way that it is possible for two drivers to record the start and end of all time group information for eight days of the week.

If the corresponding data card 7 for driver I is inserted in the data cassette at the time of recording this data, this information is simultaneously transferred to card 7 via magnetic head MK. The time group information for driver II that arises in parallel is initially only stored in the data cassette. If, for example, a driver change takes place, ie driver II then drives on instead of driver I, the device recognizes this by, for example, driver II now switching his time group switch to the driving mode of operation. At this moment this is recognized by the microprocessor. The electromagnet releases the lock 22 so that the data card 7 can be removed by driver I and driver II can insert his data card. After this card 7 has been inserted, the card is locked again and the time group recordings stored in the data cassette 3 are transferred to the data card 7 by driver II. In addition to recording the time groups for the drivers, the device detects violations of the working time regulations. If e.g. If, for example, a driver sits at the steering wheel for more than four hours, this constitutes a violation of the work schedule. These violations are stored in area d in the data cartridge. This information is also transferred to area d of data cards 7, so that data cards 7 for drivers I and II each contain information a relating to the vehicle and the personnel number. of the driver, in area b contains the data about the set work types for the respective day and in area d the compressed data about violations of the working time regulation, and not only for the respective day, but for the entire recording period of the last eight days .

In parallel to the recording of the time group data for the drivers, as is predetermined by the setting of the rotary switches 8 and 9, the vehicle-related data are determined and recorded. For this purpose, the pulse trains, which are generated by the transmitters 12 and 13 for speed and rotational speed and by the transmitter 14 for fuel consumption, are converted in the microprocessor MC in such a way that they can be sensibly recorded in the data cassette. For the speed and the speed z. B. So-called. Speed profiles generated. It is therefore determined for which period of time the vehicle was driven at certain speeds. This makes it possible to determine whether z. 3. one or the other driver has frequently exceeded the maximum speed limit or the like. On the other hand, a speed profile will be a good one the longer the duration of the journey in a certain medium speed range. The fuel consumption will be recorded in such a way that it can be interpreted as a function of the route, in such a way that, for example 10.5 l were consumed on the first 50 km of the journey, 12/9 1 on the second 50 km etc. In addition to the records in accordance with the data cassette, relating to a speed and speed profile and the fuel consumption, the records according to e are also determined and generated, which extend to the speed diagram during the last 1,000. Here, the speed values are recorded depending on the route, in order to be able to extract and evaluate this data in the event of an accident and to determine how the vehicle and driver behaved in the last seconds before the accident.

In the previous description of the mode of operation of the arrangement, it was assumed that the speed and speed sensors are connected, for example, to the data processing device 1 and that the analog value of the ^' speed via the stepper motor MS on the pointer via the microprocessor MC Z is transmitted. Of course, it is also possible, instead of the indirect display AV, to make a direct display, for example using a conventional vortex current tachometer as an analog display and converting the rotary values received at the vortex current tachometer into pulse trains and assigning them in parallel to the data acquisition device. In any case, the separation of display and recording makes it possible to separate them spatially, so that, for example, the speed display is arranged in the driver's field of vision, while the data acquisition device is arranged at a location that is not immediate must be in the driver's field of vision.

It has already been mentioned that instead of the magnetic data card 7 described here, a data card can also be used which has an integrated semiconductor module contains in the form of a memory. In this case, the contacts of the data card 7 in the inserted state could be connected directly to the address and data buses A and D, so that the data would not have to run via the interface SA.

As a special special program, a program is stored in the system memory ROM of the microprocessor MC which permits the information to be called up from the data card 7 on the display 11 when the driver sets the tap changer 10 accordingly. The various information a, b and d of the data card can be transferred to the display by different positions of the multi-stage switch 10, so that the driver can see for himself which time groups or types of work were registered for him on this day and which The device has registered violations of the Working Time Ordinance. The police can also make use of this option for road traffic checks. If there are serious violations, the police can use a simple mobile detection device according to FIG. 3 also carry out archiving of the recorded data.

In FIG. 3 shows a schematic circuit diagram of such a mobile evaluation device for the data cards 7, in FIG. 4 the computer configuration which allows the data cartridge 3 to be evaluated. It is assumed that. the mobile evaluation device 15 is either provided with its own power supply or can be connected to the vehicle police system of the traffic police. For this purpose, this device is either provided with a power supply unit NT or with a battery B3. The data card 7 is inserted into a reader 16 , in which the information on the card 7 can also be read by means of a magnetic read and write head. if fed into a microprocessor MC, which is provided with a system memory ROM and with a live memory RAM. The data can then be transferred from the microprocessor MC or from the live memory RAM to a display AZ, for example in the form of a line display. In addition or as an alternative to this, however, the microprocessor MC can also operate a strip printer DR via a control DC, so that the data which were stored in the data card can also be archived. Such a reading device for the data cards can be implemented with relatively little effort, since this creates an archivable data carrier, and at the same time both the traffic control and the driver are shown via the line display which data has been archived , but there is no evaluation of the data, so that the software effort is low.

The data cartridge 3 itself can be evaluated in a cartridge reading and writing station KS. The data obtained here are transferred to the central processing unit CPU of a computer, from there they can also be transferred to an external memory ES, to a printer DP and to a screen CRT. With the TS keyboard, information can also be entered into the computer. The evaluation device according to FIG. 4 is, of course, in the central office organization of the vehicle fleet in which the data acquisition devices 1 are used.
