Definitions

  • the invention relates to the devices defined in the preamble of claim 1 for reproducing warning messages in warning systems which are equipped with radio receivers.
  • the radio transmitter and radio receiver it is known to use the radio transmitter and radio receiver to reproduce traffic reports for the general public.
  • the traffic announcement is read by a speaker in the studio of the radio station.
  • a special announcement identifier of 125 Hz is additionally broadcast over a 57 kHz subcarrier during their duration.
  • the radio receivers are able to automatically increase the volume of the playback of the traffic announcement during such an announcement. Reading out the traffic announcement requires a great deal of time because the verbal formulation of each announcement is characterized by a high level of redundancy of the information.
  • the required airtime may not be available. This is the case, for example, if different instructions are to be transmitted in a short time via the same transmitter or the same transmitter chain to a larger number of groups of people to be warned on the radio path.
  • the invention was therefore based on the object of reducing the reception time for a warning message.
  • Figure 1 shows a block diagram
  • the device for receiving and reproducing warning messages is connected to an FM radio receiver, which uses an antenna 1 to receive the carrier of the transmitter which is tuned by means of the tuner 2.
  • the signals modulated onto the carrier are separated from the carrier in IF stage 3.
  • the usual MPX signal, which includes all information, is available at the output of IF stage 3.
  • a 57 kHz filter 4 extracts the signal components in the vicinity of the 57 kHz subcarrier frequency from the MPX signal.
  • Parallel to the input of the filter 4 is the input of the usual LF stage 7, which processes the normal program contribution of the transmitter and makes it audible via the loudspeaker 8.
  • a 57 kHz auxiliary carrier can be removed from the filter output, the amplitude of which is modulated.
  • This 57 kHz subcarrier is supplied, inter alia, to an RDS demodulator 5 connected to the filter.
  • the demodulator 5 continuously feeds an RDS block decoder 6 with pulses.
  • the block clock itself can be removed at the beginning b o and the block number at the output b n .
  • 16-bit wide memories 9, 10 are connected in parallel.
  • the 16-bit wide output of the pre-memory 9 is connected on the one hand to the 16-bit wide input of a buffer 11, on the other hand to the 16-bit wide input of a recoder 12, the 3-bit wide output of which is connected to the 3-bit wide input c 1 - c 3 of a first coincidence circuit 13 is led.
  • the 16 bit wide data output of the second pre-memory 10 is connected to the inputs of a second coincidence circuit 14, to the further inputs of which a 16 bit wide address memory 15 is connected, in which the address of the alarm system is permanently stored.
  • the 1-bit wide output of the second coincidence circuit 14 is connected on the one hand to a wake-up tone generator 16 and on the other hand to the first control input of a takeover gate circuit 17, the output line of which is connected to the takeover input of the buffer store 11.
  • a second control input of the takeover gate circuit 17 is controlled by a clock gate 23 via a timing element 18 and a first release gate 19.
  • a third control input of the takeover gate circuit 17 is connected to the 1-bit output of the first coincidence circuit 13.
  • the three further data inputs d 1 - d 3 of the first coincidence circuit 13 are connected to the outputs of three control flip-flops 24, 25, 26, each of which contains the data from the data outputs a 2 adjacent to the LSB (lowest significant bit) output, a3 and a4 of the block decoder 6 take over when their takeover input is driven by the clock gate 21.
  • the take-over input of the pre-memory 9 is controlled by the clock gate 23 via the first release gate 19, and to take over the data into the pre-memory 10 from the clock gate 22 via a second release gate 27, after which the Clock gate 20 has caused the reset of all control flip-flops in the device and the two pre-memories 9, 10.
  • the second inputs of the two enable gates 19 and 27 are connected to an enable bus 28, which is connected to the output of an undore gate 29, which in turn is controlled by three further control flip-flops 30, 31, 32.
  • the control flip-flop 32 is connected on the input side via a second AND circuit 33 to the first five, the MSB (Most Significant Bit) comprising data outputs a15 - a11 of the block decoder, while the further control flip-flop 31 is connected to the LSB data output a0 and the control flip-flop 30 is connected to this directly adjacent data output a1 of the block decoder 6.
  • the clock gates 20 to 23 are connected on the input side to the block clock output b o of the block decoder 6 and on the other hand to the block number output b n of the block decoder 6.
  • the FM radio receiver receives an endless stream of digital data via the 57 kHz subcarrier when tuned to an RDS transmitter. This data is used on the one hand to synchronize the receiver with the transmitter, to a certain extent to correct errors that have occurred in the transmission path from the transmitter to the receiver, and finally to transmit control signals for the radio receiver and for peripheral devices connected to it .
  • a library with memories 35 for defined warning messages forms the peripheral device to be controlled.
  • control signals for peripheral devices are transmitted in group 9 of the RDS signal and are repeated continuously in the endless data stream at a predetermined time interval.
  • the control signals of group 9 like the signals of the other groups, are divided into four successive blocks.
  • One of the clock gates 20 to 23 is assigned to one of these blocks.
  • the control flip-flops 24 - 26, 30 - 32 are made to take over the bits at the assigned data outputs of the block decoder 6 via the clock gate 21, which belongs to the second block. If in the second block the control flip-flop 32 detects the signal for the group 9, its output signal prepares the first undtor 29 to transmit the clock pulse from the clock gate 22, which belongs to the third block, as a takeover pulse via the release gate 27 to the Forward memory 10 and forward the clock pulse from the clock gate 23, which belongs to the fourth block, via the release gate 19 on the one hand as a take-over pulse to the preliminary memory 9 and on the other hand via the timing element 18 and the transfer gate 17 to the buffer memory 11.
  • the state of all outputs a0 - a15 of the block decoder 6 during the third block in the latch 10 is transferred.
  • the combination of the assigned outputs represents the device address. If this corresponds to the device address stored in the address memory 15, a control signal is produced at the output of the coincidence circuit 14, which triggers a wake-up tone via the wake-up tone generator 16 and, on the other hand, pre-unlocks the transfer gate 17.
  • the loudspeaker 8 of the radio can be used to reproduce the alarm tone via an OR circuit 38, but this is not a mandatory measure.
  • the takeover pulse from the clock gate 23 By the takeover pulse from the clock gate 23, the state of all outputs a0 - a15 of the block decoder 6 during the fourth block in the buffer 9 is transferred.
  • this information is used to calculate a 3-bit keyword in a recoder 12. Does this keyword match the output signal of the control flip-flops 24, 25 and 26, which is generated by the clock pulse from the clock gate 21 assigned to the second block have been set, then the coincidence circuit 13 also enables the second input in the takeover gate 17, so that the takeover pulse delayed by the timing element 18, which is assigned to the fourth block, the information contained in the pre-memory 9 , transfers to the buffer memory 11.
  • the output of the buffer memory 11 forms the interface to the peripheral device in which the memory 35 forms a library for the defined warning message.
  • a call unit 34 selects the warning message determined on the basis of the occupied outputs of the buffer memory 11, which then z. B. is output via the display 36.
  • the buffer 11 is deleted by the call unit 34 via the reset line.
  • the loudspeaker 8 of the radio can be used again for the speech reproduction via the OR circuit 38.
  • the time required for the warning message to be output via the speech processor can be used by means of the invention to initiate the output of other pre-stored warning messages in other systems of the same structure.
  • the object on which the invention is based is thus completely achieved.
