FIELD: transport.SUBSTANCE: set of inventions relates to equipment intended for protection of crew and passengers in traffic accidents. Interface to receive at least one signal is used, signal amplitude being defined by vehicle storage battery voltage or auxiliary voltage. Besides, control is used to actuate safety means in response to at least one signal. Said interface incorporates at least one circuit to detect said one signal and to generate at least one threshold of switching supply voltage generated in control unit (auxiliary voltage) maintained for preset time interval in self-contained mode at insufficient voltage level or at lost contact. Said threshold can be generated either directly from storage battery voltage (standard mode) or from amplitudes of voltage across the bus.EFFECT: self-contained uninterrupted data transfer via interface.10 cl, 6 dwg |
