1. A door lock control system integrated with sensing and audio/image identification (ID) functions, the system comprising:
- an electronic door lock mounted at a door for locking the door;
a central processor connected with an electronic control terminal of the electronic door lock for controlling the on and off of the electronic door lock, built in with an ID checking and controlling program, and connected with an memory;
an RFID card reader connected to an input terminal of the central processor for reading an RFID code of an approaching RFID card and outputting the RFID code to the central processor;
a microphone mounted at a position for receiving voices inside and outside the door and converting them into an electronic signal;
a voice ID unit connected to an output terminal of the microphone and an input terminal of the central processor and built in with multiple reference voice signals for extracting voice features in the electronic signal output from the microphone and comparing with the reference voice signals, determining whether the electronic signal matches any one of the referenced voice signals and outputting a determination result to the central processor;
an image camera disposed at an appropriate position of the door for capturing biological features of a user and outputting the captured image; and
a digital image processor connected to an output terminal of the image camera via an image processing unit and built in with multiple reference images for comparing the captured image with the multiple reference images and outputting a determination result to the central processor.

Abstract
A door lock control system integrated with sensing and audio/image identification functions includes three identification means. First, an RFID card reader obtains the identification code of a user'"'"'s RFID card to perform a first identification check. After the first check is passed, the user is asked to make a voice to be compared with a pre-stored voice for a second identification check. After the second check is passed, an image of the user is taken to be compared with a pre-stored image for a third check. After all the three checks are passed, an electronic door lock is opened.
