Abstract

The present application discloses an ultrasonic data transmission method, device, system, terminal equipment and medium. The method is applied to the transmitting end, and the transmitting end includes at least two ultrasonic signal transmitting arrays. The method includes separately determining the corresponding ultrasonic signal transmitting array. For the single-frequency ultrasonic coded signal of the information to be transmitted, different ultrasonic signal transmitting arrays correspond to different ultrasonic codes of the information to be transmitted; at least two corresponding single-frequency ultrasonic signals are transmitted to the receiving end in a focused manner through the at least two ultrasonic signal transmitting arrays The coded signal, wherein, different ultrasonic signal transmitting arrays have different frequency bands of transmitting frequencies. Since different ultrasonic signal transmitting arrays correspond to different ultrasonic encoding methods of the information to be transmitted, it increases the difficulty of cracking and strengthens the security of information protection. At the same time, when the receiving end receives at least two signals transmitted by ultrasonic signal transmitting arrays, the Decoding is performed to avoid the influence of interference signals and improve the accuracy of communication results.

Description

technical field [0001] The present application generally relates to the technical field of communication, and specifically relates to an ultrasonic data transmission method, device, system, terminal equipment and medium. Background technique [0002] There are various ways of information transmission, which are mainly divided into two categories: wired communication and wireless communication. Specifically, wired communication refers to the use of tangible media such as metal wires or optical fibers to transmit information, while wireless communication refers to long-distance transmission and communication between multiple nodes without conductors or cables, such as ultrasonic communication. , infrared communication, Bluetooth communication and Wi-Fi communication, etc. Among them, after the ultrasonic communication encodes the information to be transmitted, it is transmitted through the ultrasonic array and the subsequent decoding completes the data transmission. [0003]...
