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

Abstract

The invention discloses a hexadecimal encoding and decoding method and device for ultrasonic communication, wherein the hexadecimal encoding method for ultrasonic communication includes the following steps: S11, converting the acquired data to be transmitted into a hexadecimal code ; S12. According to the preset ultrasonic communication encoding and decoding format, the converted hexadecimal code is encoded and modulated to generate the ultrasonic signal data waveform to be sent out; wherein, the ultrasonic communication encoding and decoding format is: corresponding to 16 decimals The hexadecimal metadata sets 16 encoding sequences, and each encoding sequence is composed of N segments of ultrasonic signals sent in sequence. The frequencies of the N segments of ultrasonic signals are different from each other, and the first segment of ultrasonic waves of different hexadecimal metadata The signals are the same data header signal, and the last N-1 segment ultrasonic signals of different hexadecimal metadata are N-1 segment content signals with different arrangement and combination sequences. The technical scheme of the invention can meet the data transmission requirement when there are too many types of data.

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...
