Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0022] Such as figure 1 and figure 2 As shown, the present invention provides a Beidou / GPS multi-frequency point antenna for deep-sea smart buoys, which is composed of a multi-frequency point Beidou / GPS antenna 1, an antenna feeder and a pressure-resistant casing. The pressure-resistant shell includes a threading pipe 2, a flange 3, and a radome 4. The radome 4 is located on the top of the pressure-resistant shell and is sealed and connected to one side of the flange 3. The multi-frequency Beidou / GPS ...

Abstract

The invention provides a Beidou/GPS multi-frequency-point antenna for a deep sea intelligent buoy. The Beidou/GPS multi-frequency-point antenna for a deep sea intelligent buoy includes a multi-frequency-point Beidou/GPS antenna, an antenna feed line and a pressure hull, wherein the pressure hull comprises a threading pipe, a flange and a radome; the radome is located at the top of the pressure hull and is sealedly connected to one side of the flange; the multi-frequency-point Beidou/GPS antenna is arranged in the radome; the threading pipe is sealedly connected to the other side of the flange;and the antenna feed line penetrates the threading pipe to connect the multi-frequency-point Beidou/GPS antenna and a Beidou module in a buoy compartment. The Beidou/GPS multi-frequency-point antennafor a deep sea intelligent buoy can ensure that the intelligent buoy can work in an underwater environment with a water depth of 4000 meters, and the Beidou/GPS multi-frequency-point antenna can effectively transmit or receive electromagnetic wave signals of four frequency bands of a Beidou first generation S/L, a Beidou second generation B1 and a GPS L1 after the deep sea intelligent buoy floatson the water surface, and can provide guarantee for deep sea intelligent buoy satellite positioning and implementation of a communication function.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a Beidou / GPS multi-frequency point antenna used for deep-sea intelligent buoys. Background technique [0002] Smart buoys for the global deep ocean can break through the limitations of existing ocean observation technology, realize observation of oceans deeper than 2,000 meters, expand the temporal and spatial coverage and monitoring scale of ocean observation, realize ocean three-dimensional detection, and can carry physical, chemical, biological Various sensors such as sensors can achieve high-precision, low-drift deep-sea long-term observations, and have important applications in marine environmental monitoring, oceanographic research, ocean formation, and marine disaster forecasting. After the smart buoy completes the observation of the ocean profile, the acquired ocean data needs to be uploaded to the shore station in time for storage and analysis. In deep s...
