The main function of the whole system is that it pretend the automative fromstealing throught the vibration testing.When there is no vibration it keeps the early warningstats.When there is vibration it give an alarm. The whole system consists of three part of electrical circuit:the vibration test electricalcircuit, the control electrical circuit of the microcomputer and the the alarm electricalcircuit .The main function of the vibration test electrical circuit is that test whether there isvibration or not.When there is no vibration it output lower level.When there is vibration itoutput a digital pulse signal and send it to the control electrical circuit of the microcomputer.The control electrical circuit of the microcomputer is the core of the whole system.It take overthe signal sending from the vibration test electrical circuit and then deal it with theprogramme and control the alarm electrical circuit.When the signal it take over is the lowerlevel it keeps the alarm electrical circuit off.When the signal is the digital pulse one it turn thealarm electrical circuit on.The alarm electrical circuit consists of the voice alarm electricalcircuit and the light one. First the thesis explain the project I can take,then it introduce the function o
