Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029]In order not to add additional hardware, use software to achieve relative positioning between smart devices, so that the relative positioning is universal, and devices from different manufacturers can achieve interoperability and compatibility, and based on this to explore innovative applications of smart devices, this paper The embodiment of the invention proposes a sound (preferably ultrasound) based relative direction recognition scheme between smart devices, without adding additional hardware, software can be used to realize the relative direction recognition between two smart devices, and the positioning result is accurate and reliable.

[0030] First of all, an intelligent device refers to any device, device or machine with computing power.

Abstract

The invention provides an access controller, an access control method and a computer readable storage medium. The access controller comprises a first sound detection module; a second sound detection module; a processor which is configured to enable the first sound detection module to detect a first sound signal which is sent by the intelligent equipment and directly reaches the first sound detection module, and enable the second sound detection module to detect a second sound signal which is sent by the intelligent equipment and directly reaches the second sound detection module, wherein the first sound signal and the second sound signal are sent by the intelligent equipment at the same time; determining the time difference between the receiving moment of the first sound signal and the receiving moment of the second sound signal; determining a relative angle between the access controller and the intelligent equipment based on the distance between the first sound detection module and the second sound detection module and the time difference; and when it is determined that the relative angle is within a preset angle range, sending an unlocking instruction to the entrance guard. Intelligent unlocking based on the relative angle is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of access control, and more specifically, to an access control controller, an access control method, and a computer-readable storage medium. Background technique [0002] Sound waves are the propagation form of the mechanical vibration state (or energy) of objects. Ultrasound refers to a vibration frequency greater than 20,000 Hz, and its vibration frequency (frequency) per second is very high, exceeding the general upper limit of human hearing (20,000 Hz). People call this inaudible sound wave ultrasonic. Because of its high frequency, it has many characteristics: firstly, it has high power, and its energy is much larger than ordinary sound waves; secondly, because of its high frequency, short wavelength, not serious diffraction, and good orientation, sound waves are commonly used in industry and medicine. Ultrasound detection is performed. Ultrasound and audible sound are essent...
