Problems solved by technology

However, due to the limited bandwidth of ultrasonic waves that can be emitted by a single ultrasonic sensor, there are usually only a limited number of frequency types of ultrasonic waves that can be emitted by a single ultrasonic sensor. As a result, common ultrasonic communication methods can only transmit several different data, which is difficult Meet the data transmission needs when there are too many types of data

Embodiment Construction

[0040] 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 part 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.

[0041] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a hexadecimal encoding and decoding method and device of ultrasonic communication. The hexadecimal encoding method of the ultrasonic communication comprises the following steps: S11, converting acquired to-be-transmitted data to a hexadecimal code; S12, performing encoding modulation on the hexadecimal code obtained through conversion according to a preset ultrasonic communication encoding / decoding format, thereby generating an external sent ultrasonic signal data waveform, wherein the ultrasonic communication encoding / decoding format is as follows: 16 encoding sequences are correspondingly set for 16 hexadecimal metadata, each encoding sequence is composed of N ultrasonic signals sent in order, the frequencies of the N ultrasonic signals are mutually different, andthe first ultrasonic signals of the different hexadecimal metadata are same data head signal, and the last N-1 ultrasonic signals of different hexadecimal metadata are N-1 content signal in differentarrangement orders. Through the technical scheme disclosed by the invention, a data transmission need when the data category is too many can be satisfied.

Description

technical field [0001] The invention relates to the field of ultrasonic communication, in particular to a hexadecimal encoding and decoding method and device for ultrasonic communication. Background technique [0002] For common ultrasonic communication methods, different data are usually transmitted through single-segment ultrasonic signals of different frequencies. However, due to the limited bandwidth of ultrasonic waves that can be emitted by a single ultrasonic sensor, there are usually only a limited number of frequency types of ultrasonic waves that can be emitted by a single ultrasonic sensor. As a result, common ultrasonic communication methods can only transmit several different data, which is difficult Meet the data transmission needs when there are too many types of data. Contents of the invention [0003] The main purpose of the present invention is to propose a hexadecimal encoding method for ultrasonic communication, aiming to realize the hexadecimal encodi...
