DEVICE FOR ANALYSING CONTROL SIGNALS DELIVERED BY MEANS FOR CONTROLLING ITEMS OF SECURITY EQUIPMENT OF A VEHICLE

摘要

An analysis device (DA) equips a vehicle (V) comprising control means (MC1) connected to items of security equipment (ES1-ESJ) with pyrotechnic triggers and arranged to generate control signals intended to activate the pyrotechnic triggers upon receipt of measurement signals. This analysis device (DA) comprises analysis modules (MA1-MAJ) connected to the control means (MC1) instead of the corresponding items of security equipment (ES1-ESJ) and each comprising an input circuit having an electrical resistance identical to that of the corresponding pyrotechnic trigger, an output circuit delivering an output signal simulating the operation of said pyrotechnic trigger upon receipt of an auxiliary signal, and coupling means connected separately to the input circuit and output circuit and producing the auxiliary signal for the latter upon receipt of the control signal by the input circuit.
