Problems solved by technology
[0003] The existing underwater robot antenna tower integration design is to arrange multiple functional antennas independently in one antenna tower. In fact, each module still uses independent antennas, which takes up a lot of space
And each antenna has a corresponding receiving module, which has many components, large volume, high power consumption and high cost
Not suitable for underwater robots that require higher space and energy efficiency

Embodiment Construction
[0021] The present invention will be described in detail below with reference to the accompanying drawings for better understanding of the present patent.
[0022] The invention includes the multi-band antenna design unit of GPS / BD positioning, BD short message, UHF and WIFI, the design of the position indicating device, and the structure design of wave transmission, transparency and pressure resistance. The integrated design method includes: the multi-band antenna design unit includes: the first radiation part GPS / BD antenna L1 frequency point, B1 frequency point as positioning, S frequency point as BD short message. The second radiation part UHF antenna frequency point is 460MHz, and the bandwidth can be increased by but not limited to increasing the parasitic slot coupling of the feeding point. The third radiation part, WIFI, uses a 5.8GHZ antenna for isolation from the S frequency point. The increase in gain has little effect on the length of the antenna, increases the mai...

The invention relates to a multi-band antenna integration device for an underwater vehicle and a data acquisition method of the multi-band antenna integration device. The multi-band antenna integration device comprises a multi-band antenna design unit, a position indicating device design unit and a structure design unit, a multi-band antenna design unit and a position indicating device design unit are arranged in the structure design unit; and the position indicating device design unit is arranged below the multi-band antenna design unit. According to the invention, the first radiation part and the second radiation part are connected together through the feeder line to form two branches of the multi-band antenna, and compared with a multi-branch antenna, the interference influence is small. According to the position indicating device design unit, a plurality of LEDs connected in series are adopted to form an annular circuit, multi-directional display can be achieved, the position indicating device design unit is arranged below the first radiation part, and radiation of the first radiation part on the sky is not affected.
Description
technical field [0001] The invention relates to the field of underwater robots, in particular to a multi-band antenna integrated device and method for position indication, communication and positioning for underwater robots. Background technique [0002] With the development of underwater robots, the work of returning, salvaging and data transmission of underwater robots has become more and more important. Antennas and position indication functions are undoubtedly important equipment for underwater robots to return home and salvage. GPS positioning, Beidou positioning, radio, and wireless network data transmission all require antennas. Therefore, in order to meet the increasingly high functional integration requirements of underwater robots, it is necessary to carry out reasonable integrated design of various functional antennas. [0003] The existing integrated design of the antenna tower of the underwater robot is to independently arrange multiple functional antennas in o...
