Definitions

  • the invention relates to a code message infrared transmitter with a fixed code and a large number of possible combinations.
  • Code message transmitters are used, for example, for the remote control of security systems, particularly in the automotive industry. These transmitters are generally encoded by interrupting certain power supply lines. This mechanical and thus visible coding can easily be read optically and the number of possible combinations is also limited.
  • the present invention has the purpose of eliminating these disadvantages of the known transmitters.
  • the device according to the invention is characterized in that it contains a programmable electronic series memory, the content of which is addressed by a pulse generator, oscillator or clock generator, the content of the memory being fed to a pulse generator which feeds an amplifier, the output of which one emitting diode, while the contents of the memory is also fed to an end-of-message blocking device which monitors the read pulse generator.
  • the code is contained in an electronic programmable memory, i.e. this code cannot be read by optical means.
  • the number of possible combinations only depends on the capacity of the memory used.
  • FIG. 1 is a block diagram of a transmitter according to the invention and - Figure 2 shows a circuit diagram of the transmitter according to Figure 1 for an embodiment.
  • the device contains a memory 1 in a programmable series version, the reading function of which is controlled by the pulses emitted by a reading pulse generator 2, oscillator or clock generator.
  • the content of the memory 1 is fed to a pulse generator 3.
  • the generator 3 feeds an amplifier 4, which feeds an emitting diode 5.
  • the content of the memory 1 is also fed to a device for blocking at the end of the message 6, which monitors the encoder 2.
  • the transmitted bit contains a synchronization bit and a data bit 0 or 1.
  • all bits of the last transmitted bit (which comprises 8 bits) are set to 1, which is sufficient charging the capacitance C ( Figure 2) of the blocking device 6 enables so that the voltage at the input of the connection point IC 1 causes the same to tilt and the blocking of the oscillator 2.
  • the system can only transmit again after the supply has been interrupted or after the capacity C has been discharged.
