| Abstract: | Since an earthquake instrument system is affected by EMI(Electromagnetic Interference),then it often gives false alarm.A recognition and elimination method based on the theory of FSM(Finite State Machine) is proposed,and has been put to use in the products.The false alarm rate of the system is reduced availably,and the system reliability is simultaneously improved. |
