Description

A wave glider air profile viewing instrument

Technical field

The invention relates to the technical field of ocean observation equipment and peripheral supporting facilities, and in particular to a wave glider air profile observation instrument.

Background technique

The wave glider is an unmanned maritime vessel driven by wave energy. It has the function of precise operations in local sea areas. Because its driving force depends entirely on wave energy, and the magnitude of wave energy varies with sea conditions, the wave glider, as a fully passive drive platform, can only operate at a low speed, and its sailing speed is generally 1-3 knots. Compared with traditional fuel or electric ship operations, the operating efficiency of wave gliders is limited due to their speed. At the same time, the wave glider is a small platform, and its load carrying capacity and power supply capacity are also at a disadvantage compared to traditional fuel or electric ships. However, considering that the wave glider is low-cost and can operate unmanned, it is usually considered to launch multiple devices at one time for cluster operations to make up for the lack of efficiency and functionality.

At present, wave glider cluster formations usually use 10-20 units to operate simultaneously, and the maximum operating distance between two units can reach nearly 100km. The hull length of a wave glider is usually 2m-3m, the width is 0.6m-0.7m, and the load capacity is generally 10kg-20kg. Considering the operational stability, the antenna installation height generally does not exceed 2m. Affected by the curvature of the earth and the physical environment of the ocean, the measured effective communication distance between wave gliders through radio stations is about 2km, and the communication distance is difficult to exceed 5km. Another possible communication method is to communicate through satellites. This means that two devices tens of kilometers away need to communicate with satellites hundreds of kilometers away. The real-time, economical, reliable and Bandwidth and many other aspects are greatly restricted.

In addition, in the application process of wave glider cluster, the use of acoustic means to detect underwater navigation platforms is a routine application. However, in the current acoustic detection process, how to effectively distinguish water surface sound sources and underwater sound sources is more difficult for small platforms. There are currently two main solutions. One is to conduct on-site judgment through the camera and infrared lens carried by the wave glider itself. However, due to the curvature of the earth and the power consumption of the equipment, the range of this method is difficult to exceed 5km. This function The distance is far from matching the acoustic detection range, and long-distance water targets cannot be completely ruled out. Another way is to use manned or unmanned aircraft to eliminate the possibility of water targets, thereby determining that the sound source is an underwater target. This method costs a lot of money to fly manned or unmanned aircraft. At the same time, because there is no parking space, the aircraft must take off temporarily from the shore. Its timeliness and endurance also limit this application scenario.
