Definitions

  • the disclosure relates to a method and a system for recording position data, in particular in a toll system.
  • a known method for collecting tolls is based on a satellite-supported system.
  • a toll road network is divided into several sections, with each section being assigned a tariff that determines the amount of the toll.
  • the mapping of the toll road network to the sections forms part of the operating data of the toll system and is stored in a control center.
  • the position of the vehicle is determined at regular time intervals while driving with the aid of a global navigation satellite system (GNSS).
  • GNSS global navigation satellite system
  • the determined positions are recorded in a so-called lane file.
  • the lane file has a certain capacity.
  • the lane file is transmitted to the control center when the lane file is completely filled with positions. If the complete lane file cannot be sent immediately, for example because of a faulty or non-existent mobile phone connection between the on-board device and the control center, it is saved in the on-board device for later transmission.
  • the lane data is evaluated in the control center and the toll to be paid is calculated.
  • the position data requires a lot of local storage space in the vehicle device and generates a high transmission volume when the data is transmitted to the control center.
  • the document EP 3 136 351 A1 describes a vehicle device (on-board unit) which determines position data of a vehicle, stores it and transmits it to a control center.
  • the position data includes a first position as longitude and latitude. Subsequent positions are transmitted as deviations from the first position (so-called delta positions) in order to reduce the size of the data to be transmitted.
  • the task is to provide improved technologies for recording position data in a toll system.
  • the data quality should be high, but the amount of data generated should be as small as possible.
  • a method according to claim 1 and a data processing device according to claim 8 are disclosed. Further embodiments are subject of dependent claims.
  • the method can be performed by a processor.
  • the positional data may be stored in a memory communicatively coupled to the processor.
  • the memory can be, for example, a data carrier such as a hard disk or a flash memory.
  • the data processing device can be designed as an on-board device in a toll system.
  • the position data can be recorded with a sensor unit, for example with a GNSS receiver.
  • the sensor unit can be arranged in the vehicle device or coupled to the vehicle device.
  • the vehicle device can be assigned to a vehicle, for example arranged or installed in the vehicle.
  • the first position data item which has no relation to a previous position data item, is saved in full and is also referred to as the full data set. If the difference is smaller than the threshold value, the second position data item is stored as the difference to the first position data item and is also referred to as a difference data record. Storing the difference in position data reduces the required storage space. The comparison with the previously recorded first position date ensures that the position data is consistent and of high quality.
  • the second position datum is stored completely (as a full record) if the difference between the second position datum and the first position datum is not less than the threshold; that is, the difference is greater than or equal to the threshold. In this case there is no saving of disk space, but data quality remains high.
  • the method can be carried out as a continuous method, with multiple position data being recorded one after the other at a time interval, e.g. B. while driving.
  • Each position datum n (n is a natural number) can be compared to the position datum n ⁇ 1 recorded immediately before. If the difference is less than the threshold, the position datum n is saved as a difference record. If the difference is not less than the threshold, the position datum n is stored as a full record. Ideally, only the first position data at the start of the journey is saved as a full data set and all subsequent position data are saved as difference data sets.
  • the position data can be recorded at a time interval from one another.
  • the time interval can be 1 s, 2 s or 5 s, for example.
  • the position data in particular the first position datum and the second position datum, can include one or more parameters. Provision can be made for a difference to be formed for each parameter of the position data (e.g. the first position datum and the second position datum), with each difference being compared with an associated threshold value and with the difference data record being stored if each difference is smaller as the associated threshold.
  • each parameter may have its own associated threshold set. If one of the differences is not smaller than the associated threshold value, the (second) position datum is saved as a full data set.
  • the position data may include at least one of the following parameters: longitude, latitude, elevation, direction, distance traveled during the time between acquiring the position data (e.g., 1 s, 2 s, or 5 s), speed, and any combination thereof.
  • the position data includes longitude, latitude, direction and distance. If the method is performed using an on-board unit, the longitude and latitude correspond to the position of the vehicle, the direction corresponds to the direction of travel of the vehicle, and the speed is the speed of the vehicle.
  • the system includes a vehicle device 1 and a central data processing device 10.
  • vehicle device 1 is also referred to as an OBU (OBU—on-board unit).
  • OBU on-board unit
  • the central data processing device 10 is also referred to as the control center.
  • the vehicle device 1 has a processor 2 , a memory 3 , a GNSS receiver 4 (eg GPS—global positioning system) and a communication unit 5 .
  • the vehicle device 1 is assigned to a vehicle; it is installed in the vehicle or arranged detachably in the vehicle.
  • the processor 1 is set up, steps of the method disclosed in the present application to carry out, among other things, detecting a first position datum with the GNSS receiver 4, storing the first position datum in the memory 3, detecting a second position datum with the GNSS receiver 4, forming a difference between the second position datum and the first position datum , comparing the difference with a predetermined threshold value and, if the difference is smaller than the threshold value, storing the difference between the two position data as a difference data record in the memory 3.
  • the steps are explained in more detail below in connection with embodiments of the method.
  • the memory 3 is set up to store position data. With the GNSS receiver 4, the position of the vehicle device 1 and thus also the position of the associated vehicle is determined. In the embodiment shown, the GNSS receiver 4 is integrated into the vehicle device 1 . It can also be designed separately from the vehicle device 1 and coupled to the vehicle device 1 (not shown).
  • the communication unit 5 is set up to exchange signals and/or data with the control center 10 .
  • Vehicle device 1 can also include a DSRC communication module (DSRC—dedicated short range communication) and/or sensors for determining direction and/or speed (not shown).
  • DSRC DSRC—dedicated short range communication
  • the vehicle device 1 can furthermore have a user interface, for example comprising one or more buttons, a display device and/or an acoustic output element (e.g. piezo beeper).
  • the control center 10 has a processor 11 , a memory 12 and a communication unit 13 .
  • the processor 11 is set up to receive position data from a vehicle device 1 and to calculate a toll fee using the position data.
  • the memory 12 is set up to store received position data.
  • the communication unit 13 is set up to exchange signals and/or data with the vehicle device 1 .
  • a communication connection for the bidirectional exchange of signals and/or data between the communication unit 5 of the vehicle device 1 and the communication unit 13 of the control center 10 can be established, for example, with a mobile radio connection (e.g. 2G, 3G, 4G or 5G).
  • the communication connection can be encrypted.
  • FIG. 1 shows a first embodiment of the method that is carried out with the vehicle device 1 .
  • a first position datum is recorded with the GNSS receiver 4 .
  • the first position data is stored in the memory 3 (step 110).
  • the recorded position data is saved completely (as a full data set).
  • a second position datum is recorded with the GNSS receiver 4 (step 120).
  • a difference between the second position datum and the first position datum is formed with the processor 2 (step 130).
  • the difference is compared to a predetermined threshold (step 140). If the difference is smaller than the threshold value, the difference of the two position data (as difference data) is stored in the memory 3 (step 150).
  • a second embodiment of the method is in 3 shown. Steps 100 through 150 correspond to those associated with FIG 2 described process steps. If the difference between the second position datum and the first position datum is not less than the threshold value (i.e. greater than or equal to the threshold value), the second position datum is stored completely (as a full data set) in the memory 3 (step 160).
  • the method is performed continuously while a vehicle is in motion. This is in 4 shown.
  • a position datum is recorded (step 300) and then a difference is formed from a position datum recorded directly beforehand (step 310).
  • the difference is compared to a threshold (step 320). If the difference is smaller than the threshold, the difference (difference record) is stored in memory 3 (step 330). If the difference is not smaller than the threshold value, the position data is completely stored (as a full record) in the memory 3 (step 340). The steps are repeated until the ride is over.
  • the position data is recorded and evaluated at regular intervals of 1 s.
  • a full data record has a size of 17 bytes.
  • the position data includes the longitude, the latitude, the direction and the distance travelled. Longitude and latitude are each given in 0.001 s.
  • the direction is given as an angular measure in 0.1° and corresponds to the deviation from the cardinal point north.
  • a value of 0.0° corresponds to north, 90.0° to east, 180.0° to south and 270.0° to west.
  • the distance indicates the distance covered since the last recording, i.e. the route that was driven in the last second.
  • the time at which the position coded in the respective data record was determined is also saved for each position data item.
  • a difference data record has a size of 6 bytes. It includes the difference to a previous data set, where the previous data set can be a full data set or a difference data set.
  • the differential record includes the change in longitude from the previous position datum. The first bit indicates whether the longitude has increased (0) or decreased (1). The remaining eleven bits contain the absolute amount of the change in width (in 0.001 s). Similarly, the change in latitude compared to the previous position date is saved. Again, the first bit indicates whether latitude has increased (0) or decreased (1). The remaining eleven bits contain the absolute amount of the change in width (in 0.001 s).
  • a difference in direction indicates the change in the direction of travel compared to one second ago. The first bit indicates whether the direction of travel has turned clockwise (0) or counterclockwise (1). The remaining eight bits contain the absolute amount of the change in direction (in 0.1°). Finally, the difference data record also includes the difference distance, which indicates the change in the distance covered in the last second.
  • the size of the difference data set compared to the full data set corresponds to a compression of about 35%. Especially on longer trips, where several thousand position data are determined (3600 data sets per hour), the storage capacity required in the vehicle device and the data volume to be transmitted to the control center are greatly reduced, whereby the check ensures that the position data is consistent and a have high quality.
  • the full data set and the difference data set can also contain the speed of the vehicle.
  • the speed can be determined from the position data or provided by a speedometer of the vehicle.
  • the change in speed can also be taken into account when deciding whether a full data set or a difference data set should be stored.
  • FIGs 5 and 6 show examples of lane files in which the position data is recorded during a journey.
  • the ideal case is shown.
  • a full data set 200 is recorded at the start of the journey.
  • the respective difference from the previous position data item is less than the threshold value, and this position data is stored as difference data sets 201 .
  • FIG. 6 shows a case in which the difference in the position data does not meet the requirements while driving, ie the difference is not smaller than the threshold value.
  • full data records 210, 220 are written while driving, to which some differential data records 211, 221 then follow.
  • the specific design of the lane file always depends on the outcome of the comparison of the difference between a current position datum and a position datum recorded directly beforehand.
