Description

Control method of sailing equipment under constant water level with current
Technical Field
The application relates to the field of underwater navigation equipment, for example to a control method of underwater navigation equipment with water level determined along with water flow.
Background
The condition of marine environmental quality is closely related to marine power factors, and in offshore shallow sea areas, periodically fluctuating tide motion is the most important power factor. When the astronomical tidal wave passes from the ocean into the offshore, the nonlinear effect is enhanced significantly as the water depth becomes shallower. This generates, on the one hand, high-frequency harmonics of the astronomical partial tide, which causes asymmetry in the tide level and flow, and, on the other hand, produces a (quasi-) steady flow of zero frequency, i.e. a tidal residual flow.
For substances dissolved or suspended in seawater, including fresh water, nutritive salts, plankton, pollutants, etc., the tidal residual flow can characterize the net transport effect of periodic tidal currents on them. The direction of the tidal residual flow directly determines the direction of transport of the suspended matter by the tide, while the magnitude of the tidal residual flow represents the net transport capacity of the tidal flow. Therefore, the research on the residual tidal current can help people to find the migration rule of pollutants and understand the biogeochemical process in the sea area, thereby playing an important reference role in the site selection of sewage outlets, the formulation of relevant policies and marine management. In an offshore strong tide system, tide asymmetry and tide residual flow are basic kinetic mechanisms of offshore environment problems, and have important practical significance and scientific significance for the research of the problems.

In one aspect of the disclosed embodiments, a method for controlling an underwater navigation apparatus is provided, for example, a method for controlling a level-fixed navigation of an underwater navigation apparatus is provided.
The control method provided by the embodiment of the present disclosure, as shown in fig. 1, includes:
s101, determining the connection state of the tilt switches in the first tilt switch group in the underwater height-fixing component of the underwater navigation equipment,
and S102, controlling the underwater navigation equipment to float up or submerge according to the connection state.
The control method provided by the embodiment of the disclosure can control the floating or submerging of the underwater navigation equipment according to the connection state of the inclination switch in the height-fixing component. Alternatively, the connection state of the tilt switch herein may include both on and off states. For example: when the tilt switch is vertical, the tilt switch is in a connected state and reads 1, and when the tilt switch is tilted, the tilt switch is in a disconnected state and reads 0. The control method of the underwater navigation equipment by adopting the tilt switch can be that when the tilt switch is changed from vertical to tilt, the state of the tilt switch is changed from connection to disconnection, and the reading of the tilt switch is changed from 1 to 0; alternatively, when the tilt switch is changed from tilt to vertical, the state of the tilt switch is changed from off to on, the reading of the tilt switch is changed from 0 to 1, and the embodiment of the present disclosure controls the floating or sinking of the underwater navigation device according to the state of the tilt switch or the change of the state of the tilt switch.

Optionally, in S102, when the connection state of the tilt switches in the first tilt switch group is changed from on to off, the underwater navigation device is controlled to float.
Optionally, the number of the tilt switch sets on the flexible cable in the height determining member may be 1, and the number of the weights on the flexible cable may be 1, and optionally, both the tilt switch sets and the weights are disposed at the free end of the flexible cable. The length of the flexible cable, and the position of the tilt switch assembly on the flexible cable, can be set according to the ride height set by the underwater vehicle. In the control method of the underwater navigation equipment provided by the embodiment of the disclosure, the tilt switch can be a mercury switch. For example, when the set cruising height of the underwater vehicle is higher than 1.5m, the distance from the tilt switch group to the connection end of the flexible cable on the flexible cable is 1.5m when the flexible cable is in a straight state in the fixed height member. The underwater navigation equipment with the height fixing component is in a vertical state in the submergence process, when the underwater navigation equipment submerges to the height of 1.5m, the mercury switch on the flexible cable touches the bottom, the state of the mercury switch changes and is changed into a disconnection state from a connection state, the underwater navigation equipment is judged to submerge to the height of 1.5m, the buoyancy or gravity can be adjusted through the buoyancy driving mechanism of the underwater navigation equipment or a heavy object on the flexible cable, the underwater navigation equipment floats upwards, and the navigation height of the underwater navigation equipment is higher than 1.5 m.
Similarly, the control method provided by the embodiment of the disclosure can control the sailing height of the underwater sailing equipment to be lower than a certain height.
Optionally, in S102, when the connection state of the tilt switches in the first tilt switch group is changed from off to on, the underwater navigation device is controlled to dive.
For example, when the set cruising height of the underwater vehicle is less than 0.5m, the distance from the tilt switch group to the connection end of the flexible cable on the flexible cable is 0.5m when the flexible cable is in a straight state in the fixed height member. The underwater navigation equipment with the height fixing component is in an inclined state in the floating process, when the underwater navigation equipment floats to the height of 0.5m, the state of the inclined mercury switch changes and is changed from a disconnected state to a connected state, the underwater navigation equipment is judged to float to the height of 0.5m, the buoyancy or gravity can be adjusted through a buoyancy driving mechanism of the underwater navigation equipment or a heavy object on a flexible cable, the underwater navigation equipment is made to dive, and then the navigation height of the underwater navigation equipment is made to be lower than 0.5 m.
The control method provided by the embodiment of the disclosure can control the underwater navigation equipment to navigate within a certain height range.
Alternatively, in the aforementioned S102, when the connection state of the tilt switch in the first tilt switch group is changed from on to off, the underwater vehicle is controlled to dive,
determining a connection state of the tilt switches in the second tilt switch group in the underwater elevation member of the underwater navigation device,
when the connection state of the tilt switches in the second tilt switch group is changed from connection to disconnection, the underwater navigation equipment is controlled to float upwards,
and when the connection state of the tilt switches in the first tilt switch group is changed from disconnection to connection, controlling the underwater navigation equipment to dive.

When the underwater navigation equipment with the height-fixing member is submerged, the inclined mercury switch on the height-fixing member is in a vertical state, when the underwater navigation equipment submerges to the height of 1.5m, the first inclined mercury switch on the flexible cable touches the bottom, the state of the inclined switch in the first inclined mercury switch group is changed, the connected state is changed into the disconnected state, the underwater navigation equipment is judged to submerge to the height of 1.5m, the underwater navigation equipment is controlled to submerge continuously, when the underwater navigation equipment dives to the height of 1.0m, the state of the tilt switch in the second tilt switch group changes, the connected state is changed into the disconnected state, the underwater navigation equipment is controlled to float upwards, and when the state of the tilt switch in the first tilt switch group is changed from off to on, judging that the underwater navigation equipment floats to 1.5m, controlling the underwater navigation equipment to submerge, and completing a cycle in a height range.
