Problems solved by technology

[0002] In some industrial or military applications, it is necessary to transmit information through the enclosure of sealed metal cabins or containers (such as spacecraft, hyperbaric oxygen chambers, nuclear reactors, etc.), which are limited by the shielding effect of the metal enclosures of these cabins and containers. Traditional wireless communication technologies that use electromagnetic waves as information carriers cannot be used
At present, the most common and direct method is to punch holes in the outer shell of these metal cabins or containers for wired communication, which will destroy the structural integrity of the metal shell, thereby inevitably reducing its safety factor and increasing maintenance costs.

Embodiment 1

[0026] See figure 1 and figure 2 , a wireless communication device, including at least one ultrasonic channel, each of which includes a first transducer 2 arranged on one side of a metal barrier 1 and a first signal processing circuit connected to the first transducer 2 , the second transducer 3 arranged on the other side of the metal barrier and the second signal processing circuit connected to the second transducer 3 . Both the first transducer 2 and the second transducer 3 use electromagnetic sound transducers, and the transducers are in direct contact with the metal barrier, or do not contact so that there is an air gap between the transducer and the metal barrier, correspondingly Compared with the system using piezoelectric transducers, the use of electromagnetic acoustic transducers does not require good coupling between the transducer and the metal barrier, reducing the installation process, and at the same time realizing quick disassembly and reducing costs.

Abstract

The invention discloses a wireless communication device. The wireless communication device comprises at least one ultrasonic channel, and each ultrasonic channel comprises a first transducer arrangedon one side of a metal barrier, a first signal processing circuit connected with the first transducer, a second transducer arranged on the other side of the metal barrier and a second signal processing circuit connected with the second transducer. According to the wireless communication device, ultrasonic waves which are not in the auditory range of human ears are adopted as information conversionmedia to penetrate through the metal barrier to be used for information transmission, and high-speed and error-free information transmission is achieved under the condition that the integrity of themetal barrier is not damaged. According to the wireless communication device, the electromagnetic acoustic transducer is adopted, non-contact ultrasonic transmitting and receiving with a metal barrierare achieved, the installation procedures of the wireless communication device are reduced, meanwhile, rapid disassembling is achieved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of ultrasonic transmission, in particular to a wireless communication device. Background technique [0002] In some industrial or military applications, it is necessary to transmit information through the enclosure of sealed metal cabins or containers (such as spacecraft, hyperbaric oxygen chambers, nuclear reactors, etc.), which are limited by the shielding effect of the metal enclosures of these cabins and containers. Due to limitations, traditional wireless communication technologies that use electromagnetic waves as information carriers cannot be used. The most common and direct method at present is to punch holes in the shells of these metal cabins or containers for wired communication, which destroys the structural integrity of the metal shells, thereby inevitably reducing its safety factor and increasing maintenance costs. Contents of the invention [0003] The purpose of the present invention is to provide ...
