Definitions

  • the invention relates to the field of siren control.
  • the wireless control of the sirens takes place via a signal which is transmitted as amplitude modulation of a 57 kHz subcarrier in an FM radio transmitter signal and can be received with any radio tuner.
  • the remote control transmitter is set with a radio tuner 27.
  • a reproduction amplifier 28 is connected to the radio tuner and to this a loudspeaker 29.
  • an output of the IF stage of the radio tuner 27 is connected to a 57 kHz filter (26), to the output of which a radio data signal decoder 25 is connected for demodulating the control signal from the subcarrier amplitude, which decoder 25 has an amplitude demodulator, a bit clock regenerator and a block decoder 12 includes.
  • the amplitude demodulator supplies the bit stream for the block decoder 12.
  • the block decoder 12 has a 16 bit wide signal output. Furthermore, a block clock bus 14 and a block number bus 15 are connected to corresponding further outputs of the block decoder 12. These two bus lines control four clock gates 24, 22, 17, 7, of which the clock gate 24 assigned to the first block clock supplies the reset pulse for all memories and flip-flops in the device, while a further clock gate 22 assigned to the second block clock takes over signals in controls three flip-flops 19, 20, 21 and the other two clock gates 17 and 7 assigned to the third and fourth block clocks cause signals to be taken into and out of the memories of the device.
  • the control signal for the first flip-flop 20 provides the lowest significant bit (LSB) output in the 16-bit wide signal output of the block decoder 12, the control signal for the second flip-flop 21 the output of the block decoder, which is adjacent to the LSB output, and that Control signal for the third flip-flop 19 an AND circuit, which is connected on the input side to the most significant bit (MSB) output and its four adjacent bit outputs of the block decoder 12.
  • LSB lowest significant bit
  • MSB most significant bit
  • the 16 signal outputs of the block decoder 12 are connected to the signal inputs of a 16-bit-wide buffer store 11 for the encrypted siren address.
  • the signal transfer is triggered via gate 17.
  • one half of the signal outputs of the block decoder which also includes the MSB output, is connected to the signal inputs of an 8-bit-wide memory 13 for the keyword.
  • the signal transfer to this buffer 4 is controlled by the clock gate 7.
  • the 16 outputs of the buffer memory 11 and the 8 outputs of the memory 13 are connected to a corresponding number of signal inputs of an address decoder circuit 10, the 16-bit wide output of which is connected to the corresponding 16-bit wide signal input of a comparison circuit 8.
  • the second information for the comparison circuit is provided by an address memory 9, in which the predetermined 16-bit address of the connected siren is permanently stored.
  • a takeover gate 5 in the takeover input of the final memory 3 is prepared for the block clock pulse from the clock gate 7 via the delay circuit 6 via the coincidence output of the comparison circuit.
  • the signal inputs of this 8-bit-wide final memory 3 take over the information about the siren program to be triggered from the buffer memory 4 when the address of the connected siren program unit 1 is recognized in the received signal in the comparison circuit.
  • the command stored in the final memory 3 now determines the Sequence of switching the siren on and off.
  • a reset pulse is returned from program unit 1 to the reset input of final memory 3.
  • a digital converter 2 is to be inserted between the final memory 3 and the program unit 1, which converts the received 8-bit-wide digital signal into an assigned control signal of the program unit 1.
  • the first data block of each sample contains the identifier of the transmitter.
  • the clock pulse assigned to the first block of the radio data signal for siren control triggers the reset of the flip-flops 19, 20 and 21 and all buffers via the clock gate 24.
  • the flip-flops 19, 20, 21 are set via the clock gate 22 when the block decoder 12 has signals ready at the outputs to which flip-flops are connected.
  • the signals of this third block present at the block decoder outputs are transferred to the buffer memory 11 via the clock gate 17 if the flip-flop 21 has not been set in the preceding clock.
  • the signals at one half of the outputs of the block decoder 12, which also include the MSB output, are taken over as a keyword in the buffer memory 13 and the signals at the other Outputs of the block decoder as the triggering siren program in the buffer memory 4.
  • the content of the buffer store 4, which is designated as a siren program command is transferred to the final store 3 and thus the siren sequence is triggered.
  • the buffers and flip-flops are then reset with the first block of the next group.
  • the final memory 3 receives a reset pulse only when the program unit 1 indicates the end of the triggered siren switching sequence.
  • a switch 30 for the loud switching is provided in front of the LF reproduction amplifier 28, the control input of which is connected to the output of the takeover gate 5.
  • the 16 signal outputs of the block decoder 12 are connected to two intermediate memories 11 and 31 each having 16-bit-wide inputs.
  • the buffer store 11 records the information present in the third block cycle at the outputs of the block decoder
  • the buffer store 31 stores the data present in the fourth block cycle at the outputs of the block decoder 12.
  • the takeover input of the buffer store 31 is connected to the output of the clock gate 7.
  • the memory 13 is in turn connected to a timer 32.
  • This timer 32 e.g. B. a radio clock, calls in the memory 13 for one time unit an assigned keyword stored there.
  • both the siren address and the one to be triggered Decrypt the siren program from the 32-bit data word contained in the buffers 11 and 31.
  • the address word is compared with the address of the siren contained in the address memory 9, while the command for the siren program to be triggered is transferred to the buffer memory 4, which for this purpose is connected on the input side to six outputs of the decoder circuit 10.
