Definitions

• Figure 5 shows a block diagram describing the functional components of another element of the anti-theft system for motorcycles according to the present invention.
• the continuous exchange of information between autonomous control unit 10 and peripheral anti-theft device is regulated by a communication protocol model shown below, that also allows performing a signalling related to the removal of the peripheral anti-theft device, and in particular of the disk-blocking device from the disk- brake, activating, once having untriggered the autonomous control unit 10 with the ciphered key 60, the piezoelectric horn of the mechanical anti-theft device 20 intermittently.
• the autonomous control unit 10 After having ended the stay period, the autonomous control unit 10 will be untriggered by means of the ciphered key 60, removed from the vehicle and afterwards turned off with the suitable key 50; similarly, the portable alarm receiver 30 will be turned off through its respective turning-off key 40.
• the transfers that the communication protocol must perform are: allowing to associate the peripheral anti-theft device to the autonomous control unit 10; this operation is necessary and must be performed within the first time that one wishes to couple the peripheral anti-theft device to the autonomous control unit 10.
• This transfer is started by a PDU of the BEGIN type, that allows storing, both in the autonomous control unit 10 and in the peripheral anti-theft device, the mutual serial references (note that the serial reference of the autonomous control unit 10 is given by the 12-bit digital word that points out the respective associated portable alarm receiver 30; the serial reference of the peripheral anti-theft device, always formed of a 12-bit digitale word, is present inside its own control means mentioned below and is inserted when making the device 20); locating, during a triggering step of the autonomous control unit 10, the presence of the associated peripheral anti-theft device.
• the lock-picking action provides for a physical approaching of the thief to the mechanical anti-theft device 20; since the person is forced to handle the mechanical anti- theft device 20 during its theft action, the proximity sensor detects the presence of the subject due to the interruption of the ultrasound cone generated by the projector, thereby triggering the alarm cycle.
• the signal demodulation is preferably given to a Aurel model of the RX-4MM5 type that performs a superheterodyne demodulation of a digital signal of the 0OK type with a carrier signal at the frequency of 433.92 MHz.
• the thereby obtained demodulated signal is sent to an integrated circuit of the HT6030 type; this electronic component is a decoder that serially receives a digital word and associates it with a 12-position dip-switch (note that the positions assumed by the switches of the dip-switch of the portable alarm receiver 30 must be equal to those assumed by the localised dip-switch inside the autonomous control unit 10) .
• peripheral anti-theft device able to verify the correct exchange of information between peripheral anti-theft device and autonomous control unit 10: this would allow recognising the time in which the autonomous control unit 10 stops its correct operation due to the insufficient electric potential of rechargeable batteries, allowing the chance of timely signalling the vehicle owner, through the use of the portable alarm receiver 30, about the forced untriggering of the alarm system 1;
