Abstract

The invention provides an ultrasonic communication method. The method comprises a first step of setting a plurality of input orders to be corresponding to the cycle number of an original burst wave signal, and setting a functional instruction for controlling a controlled object to be corresponding to the cycle number; a second step of amplifying the original burst wave signal so as to form a burst wave signal, exciting an ultrasonic transmitting transducer by the burst wave signal, then sending out an ultrasonic signal loaded with the burst wave signal by the ultrasonic transmitting transducer, and receiving the ultrasonic signal by an ultrasonic receiving transducer; a third step of converting received ultrasonic signal into a digital signal; a fourth step of amplifying the digital signal, then decoding and calculating the amplified digital signal, so as to obtain the cycle number of the burst wave signal in the digital signal; and a fifth step of correspondingly controlling the controlled object according to the functional instruction corresponding to the cycle number.

Description

technical field [0001] The invention relates to ultrasonic communication technology, in particular to an ultrasonic communication method and a communication device thereof. Background technique [0002] The communication system is an important part of the control of electromechanical and electrical products. With the development of science and technology, especially the development of electronic communication technology, and the improvement of people's requirements for control, the control of the system has undergone rapid changes, and has experienced a leap-forward development from wired to wireless, from artificial to intelligent. Especially in some workplaces that may cause harm to human health and safety, wireless control of electromechanical products has been widely used. Index requirements are getting higher and higher, which has greatly accelerated the development of wireless control systems. [0003] At present, the wireless communication technology mainly includes...
