Title: Radiating cable message transmission system
IPC: H04B5/00
Filed: 1974-10-15
Abstract: 1432554 Radio signalling STANDARD TELEPHONES & CABLES Ltd 15 Oct 1974 44567/74 Heading H4L In a radiating cable system for transmitting messages modulated on a R.F. carrier, e.g. to motor vehicles, means are provided for superimposing control signals on the modulated R.F. carrier wave. A message transmitter 1 supplies the carrier wave modulated with speech signals to the two halves 2a, 2b, of the radiating cable via a hybrid transformer 3. At the end of the portion 2a a sample of the signal is derived via a directional coupler 4, limited at 5 and supplied to a phase detector 6, the other input of the phase detector being supplied by a voltage controlled oscillator 7 via a coupler 8. The phase detector output is filtered to remove the unwanted audio components and used to maintain the oscillator 7 at the same frequency and phase as the carrier wave. The output of oscillator 7 is modulated by a tone outside the speech band from an audio oscillator 10, in a balanced modu ator 9 and the resulting signal is amplified at 11 and fed to the end of the cable via circulator 12. To allow for changes in cable attenuation an automatic modulation depth control is provided by deriving a sample of the signals at the end of the cable via coupler 13 and supplying it to a detector 14. The detected tone signal is selected by a filter 15 and supplied to a comparator 16 receiving also the output of oscillator 10 the output of the comparator providing the modulating signal. More than one audio frequency control tone may be superimposed on the cable signals. Any vehicle entering the signal field at the end of cable portion 2a will first receive the superimposed tone at a greater strength than the message signals and this will actuate vehicle switching to enable the message signals to be received. For a vehicle travelling in the opposite direction its receiver will remain muted until it is outside the signal field.
