Description

Technical Field

[0001] The present invention relates to the technical field of uninhabited island early warning, and in particular to an early warning system and method for abnormal landing on uninhabited islands and reefs. Background Art

[0002] Uninhabited islands refer to islands that are not registered as places of residence for household registration. These islands are not owned by any individual or collective, but by the state. The characteristic of uninhabited islands is that they are not registered as places of residence for household registration, so there is no permanent population. These islands may be uninhabited due to their remote geographical location, harsh environment or other reasons. Nevertheless, uninhabited islands do not mean that they can be invaded or destroyed at will, because they are also protected and managed by national laws.

[0003] In addition, uninhabited islands are rich in natural resources, including but not limited to marine resources, animal and plant resources, etc., which are also protected and managed. It is illegal for individuals or groups to enter uninhabited islands without permission to carry out development or sabotage activities, which may not only pose a threat to personal safety, but also cause irreversible damage to the country's marine resources and environment.

[0004] Therefore, achieving all-round early warning of abnormal landings on uninhabited islands and reefs is of great significance to the protection of marine resources and the environment of uninhabited islands. Summary of the invention

[0005] The purpose of the present invention is to provide an early warning system and method for abnormal landing on uninhabited islands and reefs. By collecting information from offshore buoys, seabed sonar, and island and reef drone remote sensing data, comprehensive information collection is carried out, and the obtained images and location information are transmitted to the intelligent system of the emergency response command center. According to the information pushed by the early warning system, the on-site situation is analyzed and emergency response instructions are issued. At the same time, by establishing a drone base on the islands and reefs, it is ensured that after detecting illegal landing of ships or personnel, they are verified and expelled as soon as possible, thereby strengthening the monitoring of the safety of uninhabited islands and reefs and preventing illegal invasions.

[0034] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] The specific implementation of the present invention is further described in detail below in conjunction with the drawings and examples.

[0036] The embodiment of the present invention provides an early warning system for abnormal landing on uninhabited islands and reefs, such as Figure 1 As shown, the system includes a Beidou satellite module 100, a marine buoy module 200, a seabed sonar module 300, an island and reef monitoring module 400, a drone remote sensing module 500 and an intelligent monitoring and early warning system 600.

[0037] Among them, Beidou satellite module 1 is a satellite navigation and positioning system that mainly provides positioning, navigation and timing services, and has short message communication capabilities. It consists of a constellation of multiple satellites, and achieves high-precision position determination and time synchronization through the interaction of satellite signals with ground receiving equipment. The main functions of the Beidou satellite system used in this system are positioning and short message communication functions.

[0038] Figure 2 This is a workflow diagram of an early warning system for abnormal landings on uninhabited islands and reefs. Figure 2 As shown, the connection relationship and corresponding functions among the Beidou satellite module 100, the offshore buoy module 200, the seabed sonar module 300, the island and reef monitoring module 400, the UAV remote sensing module 500 and the intelligent monitoring and early warning system 600 will be specifically introduced.

[0039] The offshore buoy module 200 is communicatively connected to the Beidou satellite module 100. The offshore buoy module 2 is set on the sea surface and is used to identify the target object and send a first warning signal to the Beidou satellite module after identifying the target object; wherein the first warning signal includes the first position of the target object.

[0040] In this embodiment, the target object is a ship, a frogman, a small boat, etc. The marine buoy module 2 includes a plurality of bidirectional microwave buoys, which are arranged in a ring around uninhabited islands and reefs. Two adjacent bidirectional microwave buoys dive alternately, and the spaced bidirectional microwave buoys are connected by microwave high frequency. If the connection is interrupted, it is determined that the two bidirectional microwave buoys with interrupted connection have targets.

[0041] Specifically, a buoy is a marine monitoring device that uses the principle of its own gravity and buoyancy balance to float on the water surface and maintain stability. In this embodiment, a two-way microwave buoy is set on the outermost side of the uninhabited island reef, and an alternating dive is implemented. When the two-way microwave buoy sinks into the sea, the marine environmental parameters can be monitored; when the two-way microwave buoy floats up, the surrounding sea surface environment can be monitored. The buoys are connected by microwaves at high frequency. Once the linkage is interrupted, it means that an object has entered, and an early warning signal is generated at the same time. If the ship continues to approach the island or releases frogmen or small boats, the emergency response plan for abnormal landing is activated; if not, it ends.

[0042] The seabed sonar module 300 is communicatively connected to the Beidou satellite module 100. The seabed sonar module 300 is disposed on the seabed between the offshore buoy module 200 and the uninhabited islands and reefs. The module is used to identify the target object and send a second warning signal to the Beidou satellite module 1 after identifying the target object. The second warning signal includes the second position of the target object.

[0043] Sonar is an electronic device that uses sound waves in the water to detect, locate and communicate with underwater targets. It is the most widely used and important type of device in hydroacoustics. In this embodiment, the submarine sonar module 300 can be a submarine sonar sensor, wherein the submarine sonar sensor uses active sonar. A submarine sonar module 300 is set between the uninhabited island reef and the offshore buoy module 200 to monitor the movement trajectory of the frogman or the small boat and track it continuously. The detected location information is transmitted back through the Beidou short message and judged by the intelligent monitoring and early warning system.

[0044] The island and reef monitoring module 400 is connected to the Beidou satellite module 100 for communication. The island and reef monitoring module 400 is arranged on the island and reef, and is used to collect image data and transmit the image data to the Beidou satellite module 100.

[0045] In this embodiment, the island and reef monitoring module 400 monitors the process of specific activities or events by collecting, storing and analyzing data. For example, a 360-degree high-definition, no-dead-angle, two-way voice call intelligent monitoring device is used as the island and reef monitoring module 400. A monitoring system is reasonably deployed on the islands and reefs, and air safety monitoring is undertaken. If an unmanned aerial vehicle is detected to have arrived at the island or reef, the data is transmitted back to the emergency response command center through the Beidou communication satellite system, and the early warning system dispatches a base drone for verification and forceful expulsion. At the same time, the sea surface within 100m around the island is monitored, and the monitoring data is transmitted back to the emergency response command center, and the intelligent system determines the landing position of the boat or personnel. The intelligent system issues instructions, and voice warnings and expulsions are carried out through the island and reef monitoring system; if invalid, the intelligent monitoring and early warning system 600 activates the drone remote sensing module 500 to verify and forcefully expel.

[0046] The drone remote sensing module 500 is provided with an image acquisition unit.

[0047] Remote sensing is distant perception, and remote sensing data includes satellite images, aerial images, point cloud data (airborne, drone, etc. data) and radar data. Remote sensing data can image a large area and obtain the overall appearance of a certain area, including coordinates, spatial distribution, morphological changes, etc. In this embodiment, the remote sensing data used by the unmanned island reef abnormal landing warning system is mainly drone remote sensing data.

[0048] The main functions of the drone remote sensing module include:

[0049] Function 1: Monitoring of abnormal landing behavior: verify, identify and track the maritime vessels that continue to approach the islands and reefs through the location coordinates in the early warning information. The base station's ship automatic identification system data are connected to my country's ship automatic identification system (Automatic Identification System, AIS) shore-based system, including the ship's identity, location, size and sailing direction.

[0050] Function 2: Conduct large-scale, high-precision, and high-efficiency dynamic monitoring of uninhabited islands and reefs with abnormal landing warning systems. After the drone remote sensing module receives the warning information, the drone quickly arrives at the scene based on the location information to obtain on-site videos and images.

[0051] The drone remote sensing module 500 is set to be multiple, wherein each drone remote sensing module 500 can be implemented as a drone with the function of collecting remote control data. A drone group can be formed by setting multiple drone remote sensing modules 500, and each drone remote sensing module 500 is dispatched according to different situations to achieve different functions. For example, when the drone remote sensing module 500 does not receive the control command of the intelligent monitoring and early warning system, the drone remote sensing module 500 automatically navigates within the set area, uses the ship automatic identification system to identify the identity, location, size and navigation direction of the ship in the set area, and collects image data in the set area through the image acquisition unit.

[0052] The intelligent monitoring and early warning system 600 is communicatively connected with the Beidou satellite module 100 and the UAV remote sensing module 500. The intelligent monitoring and early warning system 600 is used to obtain the first early warning signal, the second early warning signal and the image data transmitted by the Beidou satellite module 100, identify the third position of the target object according to the image data, and control the UAV remote sensing module 500 to reach the first position, the second position and / or the third position of the target object when the first early warning signal, the second early warning signal and / or the third position of the target object are obtained, so as to obtain the on-site video image data of the target object through the UAV remote sensing module 500.

[0053] In this embodiment, the intelligent monitoring and early warning system 600 is a device with data processing and display functions, such as a computer, which can be placed in the abnormal landing emergency response command center. Based on the signal fed by the Beidou satellite module 100 and the existing image processing algorithm, the intelligent monitoring and early warning system 600 can determine the third position and category of the target object, and execute the pre-configured emergency response plan when the target object is identified.

[0054] Specifically, the abnormal landing warning system for uninhabited islands and reefs realizes the intelligent system's marine monitoring decision-making process as follows: If the marine buoy system detects that the ship continues to approach the island or releases frogmen or small boats, the abnormal landing emergency response plan will be activated; if not, it will end. If frogmen and small boats are released near the ship, real-time monitoring will be carried out, and law enforcement vessels will be dispatched immediately for questioning and expulsion. If the released small boats and frogmen continue to approach and are 100m away from the island, their movements will be continuously tracked by the submarine sonar system. The detected location information will be transmitted back to the emergency response command center through the Beidou satellite system.

[0055] The decision-making process of the land and air monitoring of the unmanned island and reef abnormal landing warning system to achieve the intelligent system is as follows: the sea surface within 100m around the island is monitored through the island and reef monitoring system, and the monitoring data is transmitted back to the emergency response command center to immediately identify the landing location of the small boat or personnel. According to the emergency response instructions issued by the intelligent system, the island and reef monitoring system is used to issue voice warnings and expel people; if it is ineffective, the intelligent system will use drones to verify and expel them by force. If an unmanned aerial vehicle is detected to have arrived at the island or reef, the data will be transmitted back to the emergency response command center through the Beidou communication satellite system, and the intelligent system will dispatch a base drone for verification.

[0056] An embodiment of the present invention provides an early warning method for abnormal landing on uninhabited islands and reefs. Based on the above-mentioned early warning system for abnormal landing on uninhabited islands and reefs, the method comprises the following steps:

[0057] S1. If the offshore buoy module detects that the ship continues to approach the island or releases frogmen or small boats, the emergency response plan for abnormal landing will be activated.

[0058] In some embodiments, the emergency response plan includes: if the frogmen and small boats are released and move forward close to the ship, real-time monitoring will be carried out through the drone remote sensing module, and a ship will be dispatched to inquire and expel them; if the released small boats and frogmen continue to approach and reach the coverage area of ​​the seabed sonar module, the seabed sonar module will continue to track the movement trajectory to detect the location information, and at the same time, the real-time detected location information will be transmitted back to the intelligent monitoring and early warning system through the Beidou satellite system.

[0059] In some embodiments, the method further comprises:

[0060] S2. Monitor the sea surface within 100m around the island through the island and reef monitoring system, and transmit the monitoring data back to the intelligent monitoring and early warning system to determine the landing location;

[0061] S3. Based on the emergency response instructions issued by the intelligent monitoring and early warning system, voice warnings and expulsions are carried out through the island and reef monitoring system.

[0062] In some embodiments, when voice warnings and expulsion are ineffective, the drone remote sensing module is enabled to collect video evidence.

[0063] In some embodiments, the method further includes: S4, if an aircraft is detected to have arrived at an island or reef, a drone remote sensing module is dispatched to collect video evidence.

[0064] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
