Abstract
An emergency control system for use in an elevator system. When an emergency situation arises in an elevator car, an elevator passenger recites a code word. A microphone in the elevator car transforms the vocal signal to an electrical signal, and using a voice-recognition system, the spoken code word is compared with a code word stored in memory. If the spoken code word matches the stored code word, control of the elevator system is switched to an emergency mode. In this mode the elevator car is brought to a predetermined landing and an intercom system providing communication between the elevator car and the guard station is activated. At the predetermined landing, security personnel are available to render assistance to the elevator passenger when the elevator doors open.
