Passenger control system during a plane flying

Passenger control system during a plane flying, adapted to keep under checking the passengers so as to prevent and in case avoid any action such as hijackments, attempts, etc., wherein the control system includes a plurality of interactive communicating units (9, 10) adapted to communicate reciprocally, of which each first unit (9) is made by an arm-band or collar (11) supported by a related passenger, and has an individual code to identify the passenger wearing thereon, and each second unit (10) is made like a remote unit available by the plane personnel and adapted to store all the codes of all the passengers and to recognize them, said first unit (9) being housed into said arm-band or collar (11) and formed by at least a detector (12) of the emotional condition change, attached to sensor means (12 bis) into contact with the person skin and sensitive to the normal and anomalous person emotional conditions, said first unit (9) being also formed by two receiver-transmitter units (13, 14) preferably of the type TAG or the like, connected to said said detector (12) and said sensor means (12 bis), of which the first receiver-transmitter unit (13) is activated by the person normal emotional conditions, and the second receiver-transmitter unit (14) is activated only by the person anomalous emotional conditions, by releasing an alarm signal with the code of the passenger, which is received and recognized by said second unit (10), and said second unit (10) being formed by control means (19), display means (20) and exciter means (23, 28), these latter being adapted to emit sequentially, through antennas (24), toward the various receiver-transmitter units (13, 14) a plurality of signals with all the stored codes of all the passengers, and these receiver-transmitter units (13, 14) when receiving these emitted signals, through related antennas (16) placed on the plane seats (15) and associated with the corresponding detectors (12), are activated to provide a related response signal, and enabled to transmit a response signal to said control means (19), through said antennas (16, 24), only when the sensor means (12 bis) sensing the anomalous emotional condition of the passenger (s) are activated, in a manner that this response signal provides for recognizing the person referred to and his position, and indicating this situation onto said display means (20).
