Definitions

  • the present invention relates to a method for prioritized Processing information according to the generic term of claim 1.
  • EP 0 797 818 B1 describes a method for radio communication between central and peripheral units especially for a traffic management system specified that the one hand a bidirectional communication between the aforementioned Units possible and on the other hand one at close range direct communication between individual peripheral units such as. Buses with each other or between a bus and a fixed unit, e.g. Traffic light system allowed. Thereby can use the scarce resource frequency optimally become.
  • EP 0 952 565 A2 describes a vehicle communication system and describes a method for the dynamic allocation of channels, that by means of distributed base stations communication between a large number of vehicles and enabled with a central station.
  • the present invention is therefore based on the object specify a method that while maintaining the known Infrastructure especially for a traffic control system allows to process information without priority that the throughput of information is affected.
  • Figure 1 shows at least one central unit 10 in the Function of a control center of a traffic engineering system and peripheral units 11 and 12 which each have a bus - in following short called bus - are assigned. Furthermore, one further peripheral unit 15 as a display unit at a bus stop shown.
  • the communication between the central unit 10 and the peripheral units 11, 12 and 15 takes place in the multiplex method in which a time slot is assigned to each peripheral unit.
  • a time slot can be provided which, as a so-called broadcast channel, is jointly accessible to all communication participants, ie to all peripheral units 11, 12 and 15 and to the at least one central unit 10.
  • the central unit transmits 10 information units INF1 to the peripheral units.
  • Such information units INF1 are also known as telegrams.
  • the structure of such an information unit INF1 can be seen, for example, in Table 1 below.
  • Surname Contents, examples .. DESCRIPTOR Describes the structure of the information unit INFO11 Display content part 1 INFO12 Display content part 2 KEYCODE1 Key code 1 KEYCODE2 Key code 2 ..
  • the structure of the first information unit INF1 is specified in the DESCRIPTOR field, in particular which fields are contained therein and information about the length of this information unit.
  • Table 1 it is assumed that based on the reported location information of a bus 11, such an information unit INF1 is transmitted to a display unit 15.
  • the display contents are contained in the fields INFO11 and possibly also in a further field INFO12, for example in the field INFO11 there is the character string "31;15.32;Schlieren".
  • the character ";” stands as a separator that separates the content.
  • This display content is shown on the display unit 15 itself in accordance with Table 2: line Departure direction 31 15:32 Schlieren
  • the central unit 10 Also from the central unit 10 is e.g. due to the reported location information of a bus an information unit INF1 with a structure comparable to Table 1 transmitted and buffered in an on-board computer of the bus.
  • the information unit contains INF1 to a bus the identical key code KEYCODE1 which was transmitted to a display unit and the course number in a field COURSE.
  • the key code KEYCODE1 be formed from the vehicle number.
  • a second information unit INF2 is transmitted as shown in Table 3: Surname Contents, examples KEYCODE2 vehicle number COMMAND2 Action, command, e.g. delete ..
  • the instruction are given Delete line in the display unit.
  • the control part of the display unit 15 when receiving the second Information unit INF2 found that the transmitted in it Key code KEYCODE2 with the previously transmitted Key code KEYCODE1 is identical, is from the control section the contents of the COMMAND2 field are executed. This is possible due to the assignment of KEYCODE1 to INFO11, which is in accordance with the transmission of the first information unit INF1 has resulted.
  • the second information unit INF2 can be one have a fixed structure or as in the case of the first information unit INF1 a variable structure. If available of a variable structure is also a DESCRIPTOR2 field intended.
  • the unidirectional communication relationship shown in Fig. 1 can also be bidirectional.
  • FIG. 2 shows a system overview in which the implementation of the inventive method explained in more detail becomes.
  • a bus stop 26 has at least one display unit 25 on which the upcoming departures represented by buses.
  • a bus 21 is at the stop 26 arrived.
  • At least one control center becomes an operator station 20 and a computer system 23 are formed as well as from radio transmission equipment including at least one antenna mast 24, which is a zone of a Local operator operated by radio. It is believed, that a first information unit INF1 already transmitted and the key code KEYCODE1 contained therein was temporarily stored in the on-board computer. The chauffeur locks the doors immediately before departure.
  • the key code KEYCODE1 including one Command COMMAND2 into a second information unit INF2 pack - cf. see table 3 - and about one provided Time slot of the radio transmission interface.
  • This information unit INF2 is from the control part of the Display unit 25 received and it is compared whether A key code KEYCODE1 has already been saved beforehand and matches the key code KEYCODE2 transmitted. If equality is found, the display "31 15.32 Schlieren "due to the content of the field COMMAND2 deleted.
  • the method according to the invention can also be used at the entrance of a bus can be used in a stop.
  • This will the instruction "flashing" is provided in the field COMMAND2.
  • this content of the field COMMAND2 causes the Departure time "15.32" in the representation according to Figure 2 is hidden and the line and destination (destination) is shown flashing.
  • the first information unit INF1 can also in Key code KEYCODE1 or additionally provided that an indication of the validity or lifespan of the Key codes is included. For example, that the Key code for single use or use of a certain command COMMAND2 is used up and at a second transmission by means of a second one Information unit INF2 in the receiving peripheral Unity no longer has an effect.
  • the method according to the invention is not based on communication limited between a bus 21 and a display unit 25.
  • a particularly advantageous application is decentralized Connection protection by the control center only is initiated, namely by transmitting a first information unit INF1 to the two buses in which Usually a feeder and a pickup vehicle.
  • the two buses can secure the connection in the bus stop area directly via second information units INF2 communicate to ensure a connection for the passengers.
  • the chauffeur can do so by a corresponding Display on an operating device assigned to the on-board computer get supported.
  • Another application of the method according to the invention is the entry of buses into a depot; possible actions are instruction for special vehicle maintenance or loading data into the on-board computer using a mass storage device.
  • the radio transmission of the second information unit INF2 are distances in the bus stop area in the On the order of a few meters to about 100 m.
  • Procedure can be provided for this transfer e.g. in a braodcast channel and doing it to reduce the transmission power as much as a minimum Receiving field strength in the above-mentioned stop area is ensured.
  • a different frequency can also be used and at most additionally on a standardized for such purposes Transmission procedures are used.
  • the application of the method according to the invention is not limited to limited communication for the public transport sector. This procedure can be used wherever a direct temporary communication between peripheral units is necessary, but this communication if possible without one direct control by a central unit should. For example, with the Process a temporary communication between individuals Terminal devices of a cellular trunked radio system realized become.
