FIELD: electricity.SUBSTANCE: signalling device comprises a transmitting and a receiving devices. A synchroniser of a transmitting device is coupled with a rotor. The first output of the synchroniser is connected to the first input of the pulse generator, the output of which is connected to the input of the power amplifier. The output of the power amplifier is connected to the input of the optical radiator, emitting via the transmitting optical system, and a polariser in direction of the reflecting surface of the rotor blade. The optical radiator is coupled via an analyser and an optical system of the receiving device with a photodetector. The output of the photodetector is connected to the first input of the amplifier, the output of which is connected to the input of the threshold device. The output of the threshold device is connected to the first input of the first and to the first input of the second counters-decoders. The first input of the first and the second input of the second counters-decoders are connected accordingly with the second and third outputs of the synchroniser. The fourth output of the synchroniser is connected with the third input of the first and the third input of the second counters-decoders. The fifth output of the synchroniser is connected to the second input of the pulse generator. The input of amplifier strobing is connected with the first output of the synchroniser. N outputs of the first and M outputs of the second counters-decoders are connected accordingly to N and M inputs of an indicator of icing availability, comprising N first and M second elements of indication, where N and M - integer numbers above zero.EFFECT: higher information value of a signalling device.3 dwg |
