Embodiment Construction

[0027] 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.

[0028] 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.

[0029] 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 determine a first relative angle between the access controller and the intelligent equipment at the first position point and a second relative angle between the access controller and the intelligent equipment moving from the first position point to the second position point; when it is determined that the moving track of the intelligent equipment meets thepreset condition based on the first relative angle and the second relative angle, an unlocking instruction is sent to the access. According to the embodiment of the invention, intelligent unlocking based on the change of the relative angle is realized.

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...
