Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] Cell phones and many other devices around have speakers and microphones. These two pieces of hardware can use sound to send and receive data, similar to what a modem does on a telephone line. This can create a silent data channel if the operating system supports sending and receiving at a high enough frequency. Ultrasound is a sound wave with a frequency higher than 20,000 Hz. It has good directionality, strong penetrating ability, and relativ...

Abstract

The invention provides a method and a device for identifying access control identity based on ultrasonic waves. The method comprises the following steps of enabling each user to install an access control APP (application) at a hand-held mobile terminal, and use the ID (identity) to register as the user of the access control APP; generating an encrypting key and a decrypting key; enabling an access control machine to obtain the information of the users, and storing into a local database; when the distance between the hand-held mobile terminal and the access control machine is controlled within the setting range, using an encrypting algorithm and the encrypting key to encrypt the ID to obtain encrypting information, converting the encrypting information into a data frame, converting the data frame into an ultrasonic signal by an ultrasonic digital encoding type, transiting the ultrasonic signal via a loudspeaker, enabling the access control machine to receive the ultrasonic signal and convert the ultrasonic signal into the data frame, demodulating, and decrypting to obtain a plain text; if the plain text is matched with the information of the local database, automatically opening a door. The method and the device for identifying the access control identify based on the ultrasonic waves have the beneficial effects that the safety is higher, the use cost is reduced, and the reliability is higher.

Description

technical field [0001] The invention relates to the field of access control identification, in particular to an ultrasonic-based access control identification method and device. Background technique [0002] With the rapid development of Internet and mobile communication technology, people put forward a higher level of security and intelligent management requirements for modern office and living places. Ordinary door lock systems and manual access management no longer meet the actual needs of modern people. In order to comply with the development of intelligent buildings and intelligent communities, the access control system must also realize a more reliable, safer and more convenient intelligent system. The intelligent access control system comprehensively utilizes sensing technology, digital information processing, computer technology, multimedia technology and network technology to realize the collection, transmission and processing of access control system information. ...
