Definitions

  • the invention relates to a method for operating a tachograph and a tachograph.
  • a monitoring device for a road vehicle and an electronic system having such a monitoring device.
  • the monitoring device comprises means for identifying the vehicle to be monitored, means for generating information representing use of the vehicle, means for acquiring information representing a technical function to be checked, means for recording information, means for processing the recorded information and means for providing results of the processing of the recorded information.
  • the monitoring device has a memory which is connectable to an operation center, and has another memory into which the results of the processing of the recorded information are written.
  • an aircraft operation data transmission and retrieval system that includes a flight recorder that receives from sensors in the aircraft Aircraft operational data stores.
  • the aircraft operational data is transmitted by the flight recorder to a processor / modem that formats it.
  • the processor Once the aircraft operational data is processed by the processor, it is transmitted to one or more wireless transmitters that transmit it. Formatting may involve data compression or insertion of error correction codes.
  • Either a ground-based receiver or a satellite receiver receives the transmitted data.
  • a method and system for managing a land-based vehicle are disclosed.
  • At least one usage-related parameter of the vehicle is detected by means of in-vehicle sensors.
  • a transfer process allows transfer of data relating to the parameter to the database.
  • a processing operation allows the transmitted data to be processed in comparison to predetermined data for determining whether actual use of the vehicle is compliant with prescribed usage.
  • the object of the invention is to provide a method for operating a tachograph and a tachograph, which enables a fast output of data.
  • the invention is characterized by a method for operating a tachograph and by a corresponding tachograph.
  • Detected data stored in a first storage area of the tachograph in a predetermined first data format are prepared according to a predetermined preparation rule.
  • the processed data will be in a predetermined second data format, which differs from the predetermined first data format, stored in a second memory area of the tachograph.
  • At least a part of the data previously stored in the second memory area becomes dependent on a request read from an external reading unit with respect to the tachograph.
  • the at least one read part of the data previously stored in the second memory area is output while maintaining the predetermined second data format via a data interface of the tachograph.
  • the processing of the acquired data and the storage of the processed data in the predetermined second data format takes place, in particular, independently of the request of the reading unit and is preferably already completely completed at the time the request is made.
  • the acquired data are already available in the predetermined second data format required for the output and can thus be output particularly fast if these data are retrieved by the request.
  • the output can thus be made without loss of time, which would otherwise result from the processing of the acquired data and for outputting in the second data format.
  • the processing of the recorded data in accordance with the prescribed preparation rule comprises determining at least one cryptographic check value as a function of the acquired data.
  • the cryptographic check value is determined as a signature.
  • the advantage is that the data are so well protected against unauthorized manipulation and thus a particularly high level of security is possible.
  • the second memory area is operated as a first ring memory. This has the advantage that always the most up-to-date data are processed and stored in the given second data format for fast output.
  • the processing of the acquired data of a respective preceding day and the storage in the predetermined second data format in the second memory area are carried out after the detected day change.
  • the advantage is that this makes the data of the respective completed day available for retrieval in the specified second data format. These can be read and output so quickly.
  • the data in the second memory area is highly up-to-date.
  • a tachograph DTCO comprises a computing unit RE and a memory SP ( FIG. 1 ). Furthermore, the tachograph DTCO has a chip card reading unit into which a chip card CK can be inserted. Such a chip card CK rejects, for example, a company that uses the tachograph DTCO in one of its vehicles, or rejects a driver who currently steers the vehicle. However, the chip card CK can also identify a workshop or a control body. Depending on the chip card CK, the access possibilities to data of the tachograph DTCO may be different. For example, garages and control bodies can be granted unlimited access rights. However, the access rights of companies to the data of the DTCO are restricted, for example, to the data of the respective company, so that access to the data of other companies is not possible.
  • the data connection DV can be wired or wireless.
  • the reading unit LE is arranged externally with respect to the tachograph DTCO.
  • the arithmetic unit RE is provided, for example, for controlling functions of the tachograph DTCO. There may also be further arithmetic units for controlling functions of the tachograph DTCO be provided.
  • the functions of the tachograph DTCO comprise data acquisition, tamper-proof storage of the acquired data, and outputting of the acquired data depending on a request A from the reading unit LE.
  • the acquired data include, for example, driving data, for example a driving speed, or a change of the chip card CK or other data that are detected during the operation of the tachograph, for example error messages.
  • the memory SP may comprise a single memory unit or two or more than two individual memory units, for example memory chips.
  • a first memory area SPB1 is provided in the memory SP.
  • the tachograph DTCO is designed to store the data acquired by it in a predetermined first data format DF1 in the first memory area SPB1.
  • the predetermined first data format DF1 is predetermined, for example, by the manufacturer of the tachograph DTCO.
  • the data acquired by the tachograph DTCO and stored in the first memory area SPB1 must be downloaded and archived at predetermined time intervals, for example approximately every three months. Furthermore, the downloading of data may also be required in vehicle inspections carried out by control bodies.
  • the reading unit LE is coupled to the tachograph DTCO.
  • a transmission protocol to be used for transmitting the data is prescribed, for example, by EU Regulation VO (EEC) No. 3821/85 Annex IB and Appendix 7.
  • EU Regulation VO EEC
  • a maximum transfer rate of 115200 bits per second is provided. As a result, it takes about 90 days to transfer the acquired data, whose data sets each have a size GR of about 1774 bytes on average, about 15.4 seconds.
  • the reading unit LE according to the aforementioned EU Regulation requires that the processed data in a predetermined second data format DF2 be output from the tachograph DTCO and transmitted to the reading unit LE.
  • the predetermined second data format DF2 is preferably predetermined by the aforementioned EU regulation and differs from the predetermined first data format DF1.
  • the predetermined second data format DF2 is prescribed by another regulation or in some other way, for example according to regulations of other states or confederations which are not members of the European Union.
  • the preparation of the acquired data and the outputting of the processed data in the predetermined second data format DF2 is time-consuming, so that in practice the downloading of the acquired data may take several minutes.
  • the tachograph DTCO is designed to prepare the data recorded and stored in the first memory area SPB1 in the predetermined first data format DF1 in advance, that is to say before the data of the tachograph DTCO are requested by the reading unit LE through the request A, and to process the prepared data in FIG to store the predetermined second data format DF2 in a second memory area SPB2 of the memory SP. If the reading unit LE sends its request A to the tachograph DTCO, then the data stored in the specified second data format DF2 in the second memory area SPB2 can be sent to the reading unit via the data interface DS of the tachograph DTCO, while maintaining the predetermined second data format DF2 without further processing or conversion LE are spent. The outputting of the data can so can be done at high speed and the data download can be significantly speeded up.
  • the first and the second memory area SPB1, SPB2 may be arranged in the same memory unit or may be arranged in separate memory units of the memory SP.
  • the first and second memory areas SPB1, SPB2 may each extend to two or more than two memory units.
  • a storage capacity of the second storage area SPB2 and preferably also of the first storage area SPB1 is dimensioned such that the recorded data of at least 90 days with average data volume can be simultaneously stored ready for retrieval.

  • the newest index NIdx is updated when a new record is stored in the second memory area SPB2. If the second memory area SPB2 is already so full that the can no longer be stored in the second memory area SPB2 completely new record to be stored, then at least one old record will be overwritten beginning with the oldest record. Accordingly, in this case also the oldest index AIdx is updated so that it points to the access control structure ZS which is assigned to the then oldest record in the second memory area SPB2.
  • the data of one day T93 is stored in the almost completely filled second memory area SPB2. However, the data of the day T93 are so extensive that the data of the days T1 and T2 must be at least partially overwritten.
