Definitions
- the invention relates to a method and a device for the selection of digitally coded traffic reports the output in a recipient.
- Radio data system an additional and inaudible transmission of digital data parallel to Broadcast programs in a data channel.
- Specifications of the radio data system for FM radio are among others in the publication Tech. 3244-E, March 1984 of the European Runfunk Union (EBU).
- Radio receivers with suitable RDS decoders can transmitted data in addition to radio reception with the Record and decode the same receiver.
- For the Data transmission is 32 groups of 104 bits each provided, each of the transmitted groups one each certain service is assigned.
- Group 8a is for Time for the transmission of digitally coded Traffic announcements provided.
- the object of the present invention is to make a selection of the traffic reports to be output enable if the user has no selection criteria can be entered. Even if the user Entering selection criteria, the number of output Traffic reports can be confusing. This is for example possible if the user is very general Enter selection criteria or if extremely many Traffic obstructions exist and are reported. For in this case, the method according to the invention is intended reasonable further selection of the output Enable traffic reports.
- This object is achieved in the method according to the invention solved in that received traffic reports a Significant degree of the respective traffic obstruction Priority is assigned and that depending on the Number of traffic reports to be output Traffic announcements can be selected according to priority. It is preferably provided that with increasing Number of traffic reports received is a priority the relevant selection threshold raised for the output becomes.
- the traffic information stored in the receiver's memory are generally valid for a limited time. Either they are through one in the traffic announcement contained time specification invalid or by a corresponding Revoke traffic report (traffic jam has cleared). For the purposes of the method according to the invention are preferred the number of valid ones in memory Traffic reports decisive.
- An advantage of the method according to the invention is that a Not many drivers of motor vehicles Traffic announcements is irritated if he is at the appropriate Traffic situation no or an unsuitable selection criterion has entered. For example, a Motor vehicle driver on a short distance trip Freeway used from one junction to the next, hardly therefore a selection of traffic reports on his Set the receiver. With the help of the invention In such a case, the procedure will also include the number of issued traffic reports restricted, however important traffic reports are still issued, for example, notices of wrong-way drivers or on Full closures.
- Another development of the method according to the invention is that with less than a first number of received traffic reports traffic reports of all Priorities are given and that with a number received traffic reports larger than a second Number is, at least all traffic reports with the highest priority.
- This development can preferably be designed in this way be that with a number of received Traffic reports between the first and the second Number is, with increasing number with low priority starting with an increasing number of traffic reports is issued. It can be provided that the number of the traffic reports issued between the first and the second number is kept constant. With the latter is a maximum amount to the user, so to speak Traffic announcements guaranteed, on which a suitable text in the instruction manual of the recipient.
- received traffic reports can be assigned to one of six priorities.
- the method according to the invention can also be used with a different number of priorities.
- An advantageous embodiment of the invention is that there is also an area selection is carried out and that those traffic reports are issued by the priority and by the Area selection are selected.
- a selection based on priority is omitted if an area selection is activated.
- FIG. 3 Before going into the flow diagrams in FIGS. 1 and 2 first becomes the receiver shown in FIG. 3 explained. This is shown as a block diagram, which does not mean, however, that he is on a realization with Help from individual circuits corresponding to the blocks is limited. Rather, the recipient is in particular advantageously with the help of highly integrated Circuits possible. Digital Signal processors are used, which with suitable Programming the shown in the block diagrams Perform functions.
- Fig. 3 shows some to explain the invention required modules of a radio receiver and in dashed framed part especially for the Existing modules.
- the ones to be received Signals are sent to a receiving part 2 via an antenna 1 fed to the output of which an RDS decoder 3 is connected is.
- a Operating unit 4 serves a microcomputer 5. This is about a frequency adjuster 6 with a control input of the Receiving part 2 and with a control input one Audio amplifier 7 connected to the desired station and the playback parameters, such as volume, treble and Depth increase, etc.
- a speaker 8 is connected to an exit of the Audio amplifier 7, a speaker 8 is connected.
- the microcomputer 5 is also connected to a clock 9, from which data can be called up, which the date and represent the time.
- TMC traffic information processing
- a Speech synthesis device 14 which decoded at 15 Traffic reports converted into voice signals and the Audio amplifier 7 fed. Additionally or alternatively can also be an optical output by characters or other symbols can be made. Traffic announcements and Administrative data records are stored in the memory 13. Read-only memories 16 and 17 contain a location list and an event list.
- the following shows a section of the event list stored in the read-only memory 17, which contains, in addition to the information according to the aforementioned standard proposal, the priority assigned to the respective event in a column P.
- the information according to the proposed standard is a text in column T that is written in the respective national language and in the code column the code to be transmitted in each case.
- the columns N, Q, T, D, U and C are of no importance for the method according to the invention and are therefore not explained further. T code N Q T D U C. P ...
- Traffic obstruction 1 D 1 U 1 2nd traffic jam 101 D 1 U 1 4th 1 km traffic jam 102 D 1 U 1 3rd 2 km traffic jam 103 D 1 U 1 3rd 3 km traffic jam 129 D 1 U 1 3rd 4 km traffic jam 104 D 1 U 1 3rd 6 km traffic jam 105 D 1 U 1 4th 10 km traffic jam 106 D 1 U 1 4th blocked 489 L 1 U 5 5 Connection lane closed 478 L 1 U 5 5 5 Parallel lane blocked 479 L 1 U 5 4th right-hand lane blocked 480 L 1 U 5 4th left lane blocked 481 L 1 U 5 4th Fast Lane blocked 482 L 1 U 5 4th Long-distance lane blocked 483 L 1 U 5 4th Local traffic lane blocked 484 L 1 U 5 3rd Accident, road closed 240 1 D 1 U 5 5 ...
- the flow diagram according to FIG. 2 represents the essential ones Parts of a program to carry out the first Embodiment of the inventive method in TMC microcomputer 11 (Fig. 3).
- Programs are still more in the TMC microcomputer 11 Programs processed, for example to control the Voice output.
- the program shown in Fig. 1 first waited at 21 whether a selected output of Traffic announcements TM should take place. This can started, for example, by an entry in this regard will. Then at 22 the current one Message counter reading n "frozen". At 23 one Count variable i set to 1, followed by another one at 24 Counter variable j is also set to 1.
- the program branches depending on whether the current message counter reading is less than or equal to the number n j of traffic reports with priority ⁇ j .
- the respective values for n j are specified in a previous initialization (FIG. 5). If this condition is not met, j is incremented at 26 and branch 25 is run through again. This continues until n is equal to or less than n j .
- a selection threshold P of the priority of the traffic reports to be output is then set to 27 at 27.
- the following parts of the program are used to select and output traffic reports whose priority is greater than or equal to the selection threshold P. This is first checked at 28 for each traffic report currently in memory. If applicable, the respective traffic report TM i is output at 29.
- the program shown in Fig. 2 starts like the program 1 first with a query 41 whether an output should be started by traffic reports. After that, at 42 n are frozen and the count variables i and j are each set to 1.
- program part 43 the current one Distribution of the number of traffic reports over the Priorities identified. In the example shown are for example 55 traffic reports with one of the Priorities 1 through 6 exist. 45 of them have one of the Priorities 2 to 6, of which 35 were traffic reports assigned one of the priorities 3 to 6. 25 traffic reports have one of the priorities 4, 5 or 6, 15 Traffic reports one of the priorities 5 or 6 and only 5 Priority 6 traffic reports.
- the count variable j is reset to 1, whereupon the program parts 45 and 46 determine which priorities are to be allowed for the message output. For this purpose, the program branches at 45 depending on whether n k is greater than or equal to n j and whether j is less than 6.
- n j is the value determined in each case at 43. If this condition does not apply, the same check is carried out with a priority increased by 1 at 46. If the condition applies, it is checked at 47 whether n j is greater than n k .
- n j that is to say the number of traffic reports with priority j or higher, which was determined in program parts 45 and 46, but greater than the constant number n k of 20, for example, the difference n D is determined in a program part 48 .
- P j
- more than n k traffic reports would be selected.
- the n D oldest traffic reports are determined at 49.
- i is reset to 1.
- Fig. 4 shows a flow chart for explaining the input a selection criterion by the user, like it for example also in the known selection processes takes place.
- a query is made as to whether a Selection criterion should be entered. Isn't that the case, the program is exited without further effect. If a selection criterion is to be entered, this will be carried out at 62, for example a selection criterion "A7" (Autobahn No. 7) or “Stadt Ober" what to say Should only traffic reports, which a street or a concern geographic area to be spent.
- the selection criterion is activated, that is, it is stored in a memory, so that Selection program has access to the selection criterion and apply it to the selection.
- Fig. 5 shows a program for initialization after the Switch on at 64, then at 65 the message memory is deleted and the message counter n is set to 0.
- n is set to 0.
- n 1 to n 6 are used at 25 in the program according to FIG. 1 as n j .
- a number n k is also specified for use in the program according to FIG. 2, which specifies the maximum number of traffic reports to be output - except for traffic reports with the highest priority.
- Fig. 6 shows a program for reception, for testing and for Storage of traffic reports.
- the branch is 71 Part of a waiting loop that is only exited when one Traffic announcement TM was received (REC). Then branches the program at 72 depending on whether this Traffic announcement already exists in the memory MEM. Is if this is the case, the time stamp of this traffic announcement becomes updated at 73 so that the traffic report a Receives timestamp which corresponds to the time of the respective corresponds to the last reception of the traffic announcement. Thereupon the program returns to the waiting state.
- the traffic report is checked at 74 whether the traffic report can be decoded and output.
- Fig. 7 shows a program for deleting stored ones Traffic reports based on this received information.
- a delete message has been received. If this is not the case, a check is made at 82 as to whether for a Traffic announcement the lifespan DUR has expired. Will If both questions are answered in the negative, the program is repeated at 81. However, if at least one of the conditions is met, it is done at 83 the deletion of the traffic report concerned in the Storage. As is common in information technology, can this by setting a feature in one Table of contents of the memory without the Traffic announcement itself is deleted.
- FIG. 8 shows a program for an additional selection that can be inserted into the programs according to FIGS. 1 and 2 at point 32.
- TM i the respective traffic report TM i whether it meets the respective selection criterion entered by the program according to FIG. 4, for example “A7”. If the traffic report does not meet this criterion, the message counter is decremented at 93, since in the subsequent selection according to the priority, one traffic report is then to be taken into account less.
- the traffic announcement TM i at 92 meets the selection criterion, it is marked separately at 94 in the message memory. Then it is incremented at 95 i, so that the next traffic report can be checked at 92. This continues until it is found at 96 that all n a traffic reports have been checked. Then one of the programs according to FIGS. 1 or 2 is continued at 32, the subsequent method steps being carried out only with the traffic reports marked at 94.
