DTMF remote audio unlocking system and method

Abstract

The invention discloses a DTMF remote audio unlocking system. The system utilizes wireless communication transmitted DTMF audio information to carry out remote control of an electronic lock. The system comprises an electronic lock, wherein opening and closing of the electronic lock are controlled by reception and comparison of a DTMF audio cipher and the electronic lock at least comprises a pick-up element for receiving the DTMF audio information, a decoding module, wherein the decoding module is used for deciphering and decoding the audio information received by the pick-up element so that concrete digital code information is obtained, and a mobile phone as a remote control terminal, wherein the remote control terminal at least comprises a cipher sending module for carrying out wireless output or loudspeaking playing on the DTMF audio cipher information. The electronic lock is used in the express delivery industry, realizes express item reception at any time by remote control, has timeliness and improves delivery efficiency.
