    1477232 Radio signalling THOMSON-CSF 22 Oct 1974 [23 Oct 1973] 45714/74 Heading H4L An automatic radio transmitter arrangement, carried by an object such as a vehicle, includes a distress signal generator which operates in response to abnormal behaviour of the object. The generator includes a transistor 1 whose collector is connected to an LC oscillatory circuit 3, 4 and whose emitter is connected to a feedback inductor winding 5. The oscillatory circuit is coupled inductively to a transmitting antenna 10. The arrangement includes an incorporated supply source 2, a relay contact 11 for connecting the supply to the oscillatory circuit and an input circuit 20, 21, 16 connected to receive trigger signals from separate devices which generate the trigger signals in response to the abnormal behaviour, e.g. accelleration or deformation of the object. As shown in Fig. 1 the oscillator 1, 3, 5 is modulated by a multivibrator 6 co-operating with RC circuit 7, 8, so that bursts of R.F. varying in frequency are transmitted when the relay contact 11 is closed. This enables the distress signal to be picked up by both amplitude and frequency modulation receivers. When closed the contact 11 connects the transmitter circuit to both the battery 2 incorporated in the arrangement and to the vehicle battery via resistor 13 and protective diode 12. It is operated by a relay coil 18 in the event of a voltage appearing at an input 16 or on the lead 43 as a result of the operation of switching devices responding to abnormal acceleration or deceleration or to deformation of the vehicle body, for example. In one arrangement a conductive mass in the form of a grooved pulley is held by a pair of springs in an opening in a metal plate, attached to a vehicle, abnormal movement of the vehicle cuasing a contact to be made and a voltage applied to terminal 16. A deformation detector consisting of a fine wire in a breakable insulating sheath may be positioned along the coachwork and arranged to supply a voltage to input 21 of NAND gate 19 which receives the same voltage on input 20 via a sturdy protected cable so that if the input to 21 is interrupted the lead 43 is energized.

    专利说明:

    Fla FIG. 1 shows a diagram of a transmitter; in fig. 2,3n4 - various elements of the shock sensor; in fig. 5 and FIG. 6 shows embodiments of the strain gauge.
    The transmitter includes a transistor 1, a power source 2, an oscillating circuit composed of inductance 3 and capacitor 4, feedback inductance 5, multivibrator 6, coupling resistor 7 and coupling capacitor 8, coupling coil 9 and antenna 10. Power supply 2 connected to the device through the contact 11 of the relay 12. A resistor 13 and a diode 14 of the load blocking circuit are also connected in series to the power supply.
    Diodes 15, 16 and an OR 17 element are provided for communication with emergency sensors.
    The impact sensor contains a metal mass of 18 e as a roller with a neck 19, which is held by elastic elements 20 and 21. The roller is equipped with a finger 22. In the device, the roller is inserted into a plate 23 with a hole 24 and fingers 25 and 26. A finger 22 is inserted between fingers 25 and 26 .
    The strain gauge contains a conductive filament 27 coated with a sheath-28 of thermosetting material.
    Conductor 27 is connected in the device through the element OR 17.
    The device works as follows
    In the event of an accident in the form of an impact, the mass 18 moves and closes with the plate 23 or the finger 22 closes with the fingers 25 and 26.
    In the event of an accident in the form of a deformation, the thread 27 is broken.
    The signal from any sensor triggers relay 12 and the voltage from Power Source 2 is fed to a G-generator, which emits distress signals to antenna 10.
