1. A multi-function alarm system for vehicle comprising a host unit (12) and at least one extension unit (11), wherein the host unit (12) at least comprises:

  • a central processing unit (CPU) (34);

    an acceleration sensor (39);

    an acceleration processor CPU(38);

    an RF transceiver (31);

    a power supply regulator (37); and

    an output unit (32, 33);

    further wherein the acceleration sensor (39) is connected to the CPU (34) through the acceleration processor CPU (38), the input end of the power supply regulator (37) is connected to the power supply controlled by the key of the vehicle while the output end of the same is connected to the CPU (34), and the RF transceiver (31) is also connected to the CPU (34) for receiving instructions and communicating with the at least one extension unit (11);

    wherein the at least one extension unit (11) at least comprises;

    a central processing unit (CPU) (24);

    a sound wave sensor (23);

    a transmission module (25); and

    power supply means (26, 27);

    further wherein the sound wave sensor (23) is connected to the CPU (24) for transmitting detection signals to the CPU (24) under the control of the CPU (24), the power supply means (26, 27) is connected to the CPU (24) for supplying power to the at least one extension unit, and the transmission module (25) is connected to the CPU (24) for transmitting the detected data to the host unit (12); and

    wherein detection of tires, devices and high deceleration are performed during the run of a vehicle, and when abnormal conditions, if any, are detected, the at least one extension unit transfers relevant data to the host unit which then analyzes and processes data from the acceleration processor and sends out warning messages.
