Abstract

The invention discloses an underwater non-contact type communicator which comprises a sealing cavity, a wireless network card, a wireless transmission circuit and a battery, wherein the wireless network card, the wireless transmission circuit and the battery are arranged in the sealing cavity; a network card antenna extends into the cavity from a front end cover of the sealing cavity to be connected with the wireless network card, a pressure-resisting antenna protective jacket is sleeved on the network card antenna, and a watertight connector is arranged on a rear end cover of the sealing cavity; the wireless transmission circuit comprises an ARM9 (Advanced RISC (Reduced Instruction-Set Computer) Machine) chip module, a serial communication module, a power supply module, a USB interface module, a JTAG (Joint Test Action Group) interface module and an SD (Secure Digital Memory) card module; the serial communication module, the power supply module, the USB port module, the JTAG port module and the SD card module are connected with the ARM9 chip module; the wireless network card is connected to the USB port module, the serial communication module and the power supply module are both connected with the watertight connector, and the other port of the power supply module is connected with the battery. The underwater non-contact communicator has the advantages of simple structure, reliable work, simple control and capability of realizing high-speed communication between devices in a deep sea high-pressure environment.

Description

Technical field [0001] The invention relates to an underwater non-contact communicator used in deep sea and other underwater environments. Background technique [0002] In the study of deep-sea environment, resources, geology, etc., the realization of communication between underwater equipment is a key technology, which is of great significance. Traditional underwater wireless communication methods include acoustic communication and optical communication. Acoustic communication has a long communication distance, but the transmission rate is slow, and optical communication is easily restricted by underwater conditions, and there is no mature technology yet developed. The radio communication technology has developed very maturely, but due to the rapid attenuation of underwater electromagnetic waves, underwater electromagnetic communication devices have not received much attention. After experimentation, we found that electromagnetic wave communication can be reliably achieved at ...
