1. the signal input system of a vehicle-mounted multimedia advertisement recreational interactive equipment, comprise taximeter (200), taxicar engine ignition inductor (300), chaufeur remote control switch (400), it is characterized in that:

  • also comprise signal input module (100), described signal input module (100) comprises surge protection and signal filter circuit (10), signal conversion and amplifying circuit (20), analog/digital conversion circuit (30), communication interface circuit (40);

    The conversion of described signal and amplifying circuit (20) are connected with surge protection and signal filter circuit (10), analog/digital conversion circuit (30) respectively;

    Described communication interface circuit (40) is connected with analog/digital conversion circuit (30), central process unit (50) respectively;

    Described taximeter (200), taxicar engine ignition inductor (300), chaufeur remote control switch (400) are all connected with surge protection and signal filter circuit (10) respectively;

    The data that central process unit (50) obtains after calculating all can be preserved in memory;

    Described taximeter (200) and described taxicar engine ignition inductor (300) send start signal by described signal input module (100) to described central process unit (50), and then described central process unit (50) starts the power-supply system of vehicle-mounted multimedia advertisement recreational interactive equipment;

    Described taximeter (200) is also for sending closing signal by described signal input module (100) to described central process unit (50), and then described central process unit (50) closes the power-supply system of vehicle-mounted multimedia advertisement recreational interactive equipment.
