Process and device for recording and registering machine-evaluated technical and organizational

The invention relates to a method and a device for recording and registering by machine evaluative technical and organizational information when operating vehicles

Tachographs are used to record and register such trip and vehicle information known, their diagrams mainly on sheets of rice or ribbons made of paper with a surface coating draw on a wax base. The stored. Guaranteed information mainly consists of analog diagram recordings that were previously only made using optical reading devices under process-related Losses can be recovered automatically.

There are several disadvantages to this method Simultaneous registration of the various acquired information of the driving condition are several complicated mechanical writing systems required. By the relative low storage density of the data carrier, the area of application is limited. Furthermore is to the machine Evaluation requires considerable technical effort, which is why an exact and complete automatic data recovery at the current state

four technology is difficult and economically hardly justifiable.

Ed a method and some device has been proposed 3UT ₁ Srfassen and registering Eotriebsgroessen, particularly for vehicles, drive to the G ο de-momentum ago. The multi-digit encoded operating values according to the dual code are registered partly continuously partly discreetly in groups of holes or impulses on the data carrier, e.g. a paper tape, and are evaluated via a corresponding device, e.g. a reader with a downstream computer system.

The disadvantage here is the relatively large scope dec technical, in particular mechanical Expenditure of the recording made in the vehicle and partially processing the registered data. This results in an economically unfavorable ratio for the user av; and operating costs for the part located in the vehicle and the stationary evaluation part the plant.

The disadvantage of this Procedure is that it is used exclusively for the registration uiicl machine evaluation of speed, especially for accident investigations,

The purpose of the invention is to cover the parts of the above to avoid the mentioned procedure and taking into account a rational and low-loss machine Recovery and evaluation of the stored information required in the vehicle to keep technical effort as low as possible.

The invention is based on the object of providing a method and a device for recording and registering the technical and organizational information essential for operational control and accounting in the operation of vehicles, taking into account machine evaluability develop «The technical process required for data acquisition and registration in the vehicle 'To limit effort to a minimum · To achieve the highest possible functional reliability and the use of rational production are preferably electronic components and elements to use »

According to the invention, the object was achieved in such a way that a method and a device were developed with which a collection and registration of machine-evaluable technical-organizational Information is made possible · Thereby take over controllable by discontinuous impulses from contactors Pulse shaper the direct input of continuous pulses into a multi-channel magnetic tape memory. In this then take the continuous

Pulse sequences indicate the various clearly evaluable states that correspond to the values of the discontinuous Impulses correspond. In addition, the discontinuous control pulses can also change polarity or cause a defined change in the duty cycle of the continuous pulse train. So is the possibility of registering and checking further information is given, with the relevant information parameters can only assume two different states in relatively long time intervals. For the exchangeable data carrier is also a recording for an information carrier for one-time use Marking with a special signal provided. The marking is triggered as soon as it is inserted into the the magnetic tape storage takes place. This is an identification of the memory is given during the evaluation and the start time of the storage process is precisely marked.

The direct, unencoded information storage of this procedure guarantees with relative low technical and mechanical effort for the magnetic tape memory a high degree of functional reliability. This also automatically sets the process-related information losses and the In some cases, manual data entry is required to reduce the error rates to a minimum.

Another advantage of the invention-based Loeeung is that a combination with ready

existing devices, ζ. B. a traditional one 7-day tachograph, can be done so that both a display and recording with immediate visual evaluability as well as the later machine evaluability of the other data carrier is given, which gives the user optimal use allowed.

To monitor the function of the device a test unit with control circuits is provided, which monitors the rotating elements of the drive of the magnetic tape storage.

The invention is intended to be based on an example of a guide and the accompanying drawings are explained in more detail. It shows

Further positive and negative pulses mark constant sections on track 26 of the magnetic tape of the distance covered.
