Definitions
- the invention relates to a warning device for motorists with a transmission device which is set up to transmit at several different frequencies stored in a frequency memory of at least one radio frequency range.
- warning devices are their relatively high inertia. In the best case, it takes several minutes for a ghost driver message to reach the endangered driver, as soon as a ghost driver is recognized, since the message must first reach a radio station, which then emits a warning.
- a warning device of the type mentioned is apparent from DE 40 05 445 AI.
- an accident vehicle is to repeat an announcement on the three to five frequencies with the strongest reception.
- a pilot tone is used here
- the cyclic announcement on several frequencies leads to delays of the order of one minute if, for example, only the last frequency within the cycle is received. This means, for example, that the warning of a ghost driver is hardly possible, since he has already covered a long distance within the stated time and is therefore also outside the transmission range or may already have caused an accident.
- EP 0 942 402 A2 describes an emergency warning device for emergency vehicles which, in addition to acoustic and / or optical warning signals, emits a warning on a frequency in a radio band. This is done on a single fixed frequency, e.g. B. at the upper or lower end of the FM radio range, provided that the receiver is then tuned to this frequency.
- an RF stage For receptions with two RF input parts, which are de facto required, an RF stage must have an automatic station search.
- the disclosed facility therefore not only sets special ahead of the road users, but is also characterized by additional delay times due to the coordination process.
- warning direction for emitting warning messages is simultaneously formed on several different frequencies via at least one antenna.
- the principle on which the invention is based is based on the fact that motorists who are in a certain danger zone have switched on a radio receiver in the majority of cases, in Central Europe usually in the FM radio field. Since according to the invention warning messages on several, for. B. 20 frequencies are emitted at the same time, it is possible to de facto reach every driver who listens to the radio or at least has his device switched on, provided, of course, that on the one hand the locally relevant frequencies are selected and the transmission power is sufficient to in in a narrowly limited area to displace the radio station set in each case in terms of HF.
- At least one memory is provided for acoustic warning messages.
- acoustic warning messages For example . the text “Warning you have used the wrong driveway and will be ghost drivers” or “acute ice danger” etc. could be stored on a memory so that the warning is understandable without further considerations.
- At least one sensor is provided for generating a trigger signal, which thereby results in no further delays, e.g. B. by operating personnel, a warning can be initiated.
- Sensors that come into question here are known, for example inductive loops in the road, temperature sensors, smoke gas sensors etc.
- the transmission device has a plurality of carrier generators with modulators assigned to them, and the modulated carriers are fed to a common HF output stage.
- a stationary, scanning monitoring receiver with at least one antenna which scans the at least one radio frequency range at predeterminable time intervals and supplies detected and predeterminable criteria of radio transmitters to the frequency memory of the transmission device for storage for storage , Since it is not known which transmitter the driver to be warned has just tuned in, this measure achieves an extremely high probability of actually reaching the driver. It is particularly appropriate here if the specifiable criteria include a minimum field strength on the at least one antenna. Certain RDS identifiers can also expediently be assigned to the frequencies.
- the flexibility and economy of the warning device can be further increased if the monitoring receiver in the non-scanning state monitors a predefinable frequency of a transmitter with an RDS function for messages, and forwards received messages to the transmitter device and / or to controlled display devices.
- the transmitter In order to reach drivers who have turned their radio down or are listening to a tape or CD, it is advisable for the transmitter to emit a hit fic announcement bit based on the RDS system.
- the transmitting device In order to increase the effectiveness of the warnings, it may be useful if the transmitting device emits an alarm bit based on the RDS system.
- FIG. 3 shows the transmission device with its modulators in a block diagram.
- a transmission device TRX which can radiate via an antenna SAN, is equipped with a frequency memory FME, an output stage HFE, a modulator block MOD and a frequency memory FME for a number of frequencies, for example in the FM radio band, that in is generally between 76 and 108 MHz.
- the frequency memory FME can specify the frequency here either from a scanning receiver UWE or from another, e.g. B. also get manually operated input ENG.
- An antenna EAN is assigned to the receiver UWE, but the transmitter TRX and receiver UWE can have a common antenna when observing generally known precautions.
- An audio signal s s from a voice memory SSP and / or a further, in particular digital signal Sd from another source QEL can be fed to the modulator block MOD.
- the invention also provides that the transmitter TRX is started on the basis of a trigger signal s a , which can originate from a sensor SES, which, for. B. is triggered by ghost driver cars.
- a trigger signal s a can also come from another source SOV, in the simplest case a manually operated switch.
- the scanning receiver UWE is followed by a spectrum analyzer SAL, which here scans the entire FM range, ignoring transmitters or their frequencies whose reception field strength is below the minimum field strength required for normal radio reception. After one or more runs, a spectrum of occupancy of the possible frequencies that is representative of the receiver location is obtained. The frequencies determined, twenty in the example described, are then stored in the frequency memory FME.
- the modulator block MOD in this embodiment contains twenty carrier generators PO1 ... P20, which, for. B. are built on a PLL basis and their frequencies are determined via a frequency signal f from the frequency memory FME.
- the generators POl ... P20 are each followed by individual modulators M01 ... M20, the outputs of which are fed to the common RF power output stage HFE via a coupling network KOP.
- the signals s s , s a are supplied to the individual modulators M01 ... M20.
- the senor SES In the area of a motorway entrance there is on the one hand the sensor SES - it can of course also be several sensors that also work according to different principles - and on the other hand a warning system connected to it, consisting of the monitoring receiver UWE and the transmitter TRX. Vehicles driving against the motorway trigger the SES sensor, so that the HFE power amplifier is started and a warning message is broadcast simultaneously from the SSP voice memory on twenty radio frequencies.
- the warning device is set up in the vicinity of the sensor SES and the transmitting antenna SAN can be formed, for example, by a correspondingly insulated and measured section of a guardrail.
- the transmit power of the output stage HFE is dimensioned such that the signal is strong enough in a range of a few hundred meters to displace other transmitters in the receiver of a motor vehicle.
- the "beginning" ghost driver can be warned via his car radio and be advised that he is about to become a ghost driver. It is understandable that if possible an antenna will be used for the transmitter which has less omnidirectional characteristics, but that in Question coming road covers as accurately and as far as possible.
- monitoring receiver UWE Since the monitoring receiver UWE is constantly in operation, control can also be carried out via RDS from a center in order to send out other information, such as. B. enable traffic jams.
- the monitoring receiver USW is programmed so that it only receives one radio program in the idle phase. Since the RDS can also be used for paging and is also used, other pre-stored messages or displays, such as controlled traffic signs, can also be issued or displayed.
- the traffic announcement bit TA already mentioned can expediently also be emitted in order to, for example, B. to switch from CD to radio, and further an alarm bit AB, which to trigger other functions, for. B. can be used to emit a loud sound.
- the invention preferably uses a stationary warning device on e.g. B. places endangered by ghost drivers that the warning device could be used with many advantages but also in police vehicles etc. as well as in traffic helicopters to be able to address drivers in emergencies.
