Abstract

The invention discloses a wireless sensor communication device embedded in metal and a communication method thereof. In some metal structures, it is not required to have any gaps and wireless sensors need to be embedded in the structure. Communication and power supply for these wireless sensors is difficult. The invention relates to a wireless sensor communication device embedded in metal, which includes a dual-purpose circuit for charging and transmission and a dual-purpose circuit for power supply and collection. The dual-purpose circuit for power supply and acquisition includes a signal generator, a first resonant amplifier, a first ultrasonic transceiver and a signal acquisition module. The charging and transmission dual-purpose circuit includes a second ultrasonic transceiver, a first data selector, a second data selector, a rectification adjustment module, an anti-reverse diode, a battery, a controller, a NAND trigger, a third data selector, a modulus Conversion module and data return module. The invention communicates and transmits power with a wireless sensor completely embedded in solid metal through ultrasonic waves, and overcomes the Faraday shielding effect of the metal.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic sensors and wireless communication, and in particular relates to a wireless sensor communication device embedded in metal and a communication method thereof. Background technique [0002] In recent years, there has been increasing research on developing structural health monitoring (SHM) systems to provide structural integrity and damage prediction information for aging civil infrastructure, industrial machinery. Such SHM systems typically employ wireless sensor networks distributed at different locations within the structure to monitor structural properties such as strain, acceleration, acoustic properties, temperature, and electrical impedance. [0003] In some special applications (such as armor plate, ship hull, aircraft fuselage or nuclear waste container), the structure itself is required to have no gaps, which will not cause structural weakness or leakage, so it is necessary to embed wir...
