Elevator monitoring instrument for elevators will be applied with elevator controlling system together to make the elevator be governed effectively before earthquake coming or during earthquake striking. Before earthquake coming, earthquake monitoring instrument for elevators can detect earthquake wave in advance, then it will output alarm contactor that will be adopted by elevator controlling system. According to the contactor information, elevator control system makes the elevator stop and open the door at the nearest floor and release the passengers. In this way, maximum passengers will be survived and elevator can be protected from damage.
