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.
  • a device which overcomes these disadvantages by providing a programmable electrical memory, a clock which addresses the content of the memory, a pulse generator, the input of which is supplied with the content of the memory Amplifier, which is connected to the output of the pulse generator and which drives an emitting diode, and has a blocking device which controls the clock generator and blocks the transmitter after sending a message.
  • This known device offers a large number of possible combinations, but has the disadvantage that the blocking device is triggered by opening the switch which causes the code message to be sent. This makes it necessary to keep the switch pressed until the end of each program. An accidental opening of the switch also leads to the sudden termination of the transmission process.
  • the object of the invention is to improve the blocking device of a code message infrared transmitter so that the blocking device is independent of a switching operation and only effective at the end of each transmission process.
  • the blocking device has a gate, the input of which is connected to an RC time constant element, which is loaded by a sequence of bits of the high-level state "1" sent at the end of each message so that the gate is binary Value changes.
  • 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.
  • 8 memory bits are used to define a sent byte.
  • the byte sent contains a synchronization bit and data bits 0 or 1.
  • all bits of the last sent byte (which comprises 8 bits) are set to 1, which means that the capacity C ( Figure 2) of the blocking device is sufficiently charged 6 allows the voltage at the input of the connection point IC to tilt and block the oscillator 1 2nd causes.
  • the system can only transmit again after the supply has been interrupted or after the capacity C has been discharged.
