Description

Technical Field

[0001] The present invention relates to the technical field of ocean surveying and mapping, and in particular to an ocean surveying and mapping data collection and processing system and a processing method. Background Art

[0002] At present, for ships sailing on the sea, the complex marine meteorological environment and changes in waters will have an impact on the ships. For example, strong winds and waves on the sea surface may affect the navigation operation of the ship, increasing the complexity of ship driving; thick fog on the sea surface will cause visibility to decrease, which will have a certain impact on the navigation and communication of the ship; new reefs and islands in the ocean will affect the navigation of ships that have passed through in the past. Existing ocean mapping buoys, unmanned mapping ships, integrated mapping ships, etc. will further map the hydrological information of the ocean, which can speed up the update of ocean mapping data.

[0003] With the full coverage of Beidou satellites, some existing marine surveying and mapping equipment usually use Beidou short messages to transmit data in order to improve the processing of marine surveying and mapping data, and then summarize and process it at the back end. However, when there are many surveying and mapping equipment in a certain time and area, sometimes there will be queue congestion. Especially when there are integrated surveying and mapping ships near surveying and mapping buoys and other equipment, it is not possible to use the integrated surveying and mapping ships to process the surveying and mapping information. Summary of the invention

[0004] To this end, the present invention provides a marine surveying and mapping data collection and processing system and processing method to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A marine surveying and mapping data collection and processing system, including front-end surveying and mapping equipment for collecting marine surveying and mapping information, relay surveying and mapping buoys capable of pre-processing surveying and mapping information, integrated surveying and mapping ships capable of processing surveying and mapping information, shore-based radar stations for receiving information, satellites, and data centers capable of storing and processing surveying and mapping information;

[0007] The front-end surveying and mapping equipment includes several unmanned surveying and mapping ships, unmanned submersibles and ocean surveying and mapping buoys distributed on the ocean; the unmanned surveying and mapping ships can directly transmit information to the integrated surveying and mapping ships; they can also transmit information to shore-based radar stations via satellites; when approaching an ocean surveying and mapping buoy, the unmanned surveying and mapping ship can transmit its own surveying and mapping data to the ocean surveying and mapping buoy; the ocean surveying and mapping buoy can survey and collect ocean information of the current longitude and latitude area;

[0008] Relay mapping buoys are similar to ocean mapping buoys in that they can collect information about the current sea area. Relay mapping buoys are also equipped with information processing systems.

[0009] The integrated surveying and mapping ship can directly receive data information from various surveying and mapping equipment in the nearby sea area, including information pre-processed by relay surveying and mapping buoys, and directly process the data through the equipment on board; when the integrated surveying and mapping ship is close to the shore-based radar station, the information is directly transmitted to the shore-based radar station and then to the data center for storage; when it is far away from the shore and in the deep sea, it is directly uploaded to the data center through satellite communication; generally, for the sake of efficiency, it is directly transmitted to the data center through satellite communication;

[0010] The shore-based radar station is used to receive and transmit information from surveying and mapping equipment, and can also send information;

[0011] The data center can store the information processed by the comprehensive surveying and mapping ship and update it to the database. It can also process the surveying and mapping information of each surveying and mapping equipment and save and update the processed information to the database.

[0012] Furthermore: the unmanned submersible is deployed by the integrated surveying and mapping ship, and the unmanned submersible can directly transmit information to the back end via satellite. At the same time, the unmanned submersible can transmit information to the integrated surveying and mapping ship in the initial stage, and when the integrated surveying and mapping ship is far away, the data is transmitted via satellite.

[0013] Furthermore: when the ocean surveying buoy receives information transmitted by the unmanned surveying ship, it packages the information together and transmits it to the relay surveying buoy. The information processing system of the relay surveying buoy pre-processes the information of the ocean surveying buoy and the unmanned surveying ship; the relay surveying buoy transmits the pre-processed data to the shore-based radar station via satellite communication; in addition, when there is an integrated surveying ship near the relay surveying buoy, the pre-processed information is transmitted to the integrated surveying ship.

[0014] Furthermore: the information processing system includes a data receiving and storage module, a data analysis module and a data preprocessing module; the data receiving and storage module is used to receive and store data information from the unmanned surveying ship and the ocean surveying buoy; the data analysis module compares and analyzes the data from the unmanned surveying ship with the data from the ocean surveying buoy to analyze key hydrological elements.

[0015] Further: When the data analysis module performs analysis, the specific steps are as follows:

[0016] (1) Filter the information to see if there is any equipment failure. If there is, all the information about the equipment is discarded;

[0017] (2) Classify and filter the information based on the location data; discard the information with large location differences;

[0018] (3) According to the time information, the information at different times in the same area is classified, and then the subsequent wind speed, air temperature, water temperature and air pressure are compared. If the data difference is within a given range, the data of the previous time is discarded and the data of the most recent time is retained; if the difference of wind speed, air temperature, water temperature and air pressure is large, all data information is retained;

[0019] (4) The retained data is classified again based on time and location information.

[0020] Furthermore: the data preprocessing module can preprocess the information classified by the data analysis module, and for those with numerical differences within a given range or no differences, at the same time, the surveying and mapping information of equipment belonging to different locations but the same area is preprocessed, and only the surveying and mapping information of the surveying and mapping equipment at the center of the area is sent; for those with large differences, all are sent, and the information to be sent is transmitted in the format of Beidou short messages, in which the content of the telegram is the key hydrological elements.

[0021] The present invention also discloses a method for collecting and processing marine surveying and mapping data, which is characterized by comprising the following specific steps:

[0022] S1. The ocean surveying buoy transmits the surveying data to the shore-based radar station via satellite communication; if there is an ocean surveying buoy near the unmanned surveying ship, the nearby data will be transmitted to the nearby ocean surveying buoy first;

[0023] S2. The ocean surveying buoy transmits the data of the unmanned surveying ship and itself to the relay surveying buoy, and the relay surveying buoy pre-processes the data of the unmanned surveying ship;

[0024] S3. The relay mapping buoy transmits the pre-processed data to the shore-based radar station via satellite communication;

[0025] S4. When there is an integrated surveying ship near the relay surveying buoy, the relay surveying buoy transmits the pre-processed data to the integrated surveying ship, which processes the data of the unmanned underwater vehicle carried by itself and the data of the relay surveying buoy to obtain the integrated data, and then transmits it directly to the shore-based radar station via satellite;

[0026] S5. The shore-based radar station processes the received data and transmits the processed data to the data center. The integrated surveying and mapping ship can connect to the data center and obtain the relevant required data, so that the marine surveying and mapping data can be updated in real time.

[0027] Further: Before the unmanned surveying vessel approaches an ocean surveying buoy or a relay surveying buoy, it will transmit data via satellite communications.

[0028] Furthermore: The relay mapping buoy mainly analyzes, classifies, discards and stores the collected data, screens out and discards useless information first, and reduces the amount of data transmission while ensuring data reliability.

[0029] The present invention has the following advantages: the relay surveying buoy can pre-process the information collected by the unmanned surveying ship and the ocean surveying buoy, reducing the amount of data transmitted through satellite communication; at the same time, the information of the front-end surveying equipment can be preferentially collected on the nearby comprehensive surveying ship for data processing, thereby improving the timeliness of data processing.

[0034] The following is an explanation of the implementation of the present invention by specific specific examples. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. It should be understood that these embodiments are only to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field can make some non-essential improvements and adjustments to the present invention based on the contents of the above invention; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1 As shown, a marine surveying and mapping data collection and processing system in an embodiment of the first aspect of the present invention includes a front-end surveying and mapping equipment for collecting marine surveying and mapping information, a relay surveying and mapping buoy that can pre-process the surveying and mapping information, an integrated surveying and mapping ship that can process the surveying and mapping information, a shore-based radar station that receives the information, a satellite, and a data center that can store and process the surveying and mapping information.

[0036] The front-end surveying and mapping equipment includes several unmanned surveying and mapping ships, unmanned submersibles and ocean surveying and mapping buoys distributed in the ocean. The unmanned surveying and mapping ships include unmanned surveying and mapping ships released from shore bases and unmanned surveying and mapping ships released from integrated surveying and mapping ships.

[0037] The unmanned surveying ship can directly transmit information to the integrated surveying ship; the unmanned surveying ship is also equipped with a satellite equipment user terminal, which can transmit information to the shore-based radar station via satellite; in addition, the unmanned surveying ship stores the latest location data information of the ocean surveying buoy. When approaching the ocean surveying buoy within a certain range, the unmanned surveying ship can transmit its own mapping data to the ocean surveying buoy; for example, it can be set to transmit information to the ocean surveying buoy when it is 10 nautical miles away from the ocean surveying buoy.

[0038] The unmanned submersible is deployed by the integrated surveying and mapping ship. The unmanned submersible can directly transmit information to the back end via satellite. At the same time, the unmanned submersible can transmit information to the integrated surveying and mapping ship in the initial stage. When the integrated surveying and mapping ship is far away, the data will be transmitted via satellite.

[0039] The ocean surveying buoy can survey and collect ocean information of the current longitude and latitude area. The ocean surveying buoy here can be a single-point moored buoy or a three-point anchored moored buoy.

[0040] Relay mapping buoys are similar to ocean mapping buoys in that they can collect information about the sea area where they are currently located. At the same time, relay mapping buoys are also equipped with information processing systems.

[0041] When the ocean surveying buoy receives information transmitted by the unmanned surveying ship, it can package the information together and transmit it to the relay surveying buoy. The information processing system of the relay surveying buoy can pre-process the information of the ocean surveying buoy and the unmanned surveying ship; the relay surveying buoy will transmit the pre-processed data to the shore-based radar station via satellite communication; in addition, when there is an integrated surveying ship near the relay surveying buoy, the pre-processed information can also be transmitted to the integrated surveying ship.

[0042] The information processing system is Figure 2 As shown, it includes a data receiving and storage module, a data analysis module and a data preprocessing module; the data receiving and storage module is used to receive and store data information from the unmanned surveying ship and the ocean surveying buoy; the data analysis module can compare and analyze the data from the unmanned surveying ship with the data from the ocean surveying buoy, and analyze key hydrological elements, such as time, location, wind speed, wind direction, temperature, relative humidity, air pressure, water temperature and salinity.

[0043] When the data analysis module is analyzing, the specific steps are as follows: first, screen the information for equipment failure. If there is any, all the information of the device is discarded; second, for information about equipment without failure, classify and screen the information according to the location data; discard information with a large location difference. For example, if the distance difference between the unmanned surveying ship and the ocean surveying buoy exceeds 15 nautical miles, the data under the location information of the unmanned surveying ship will be discarded; third, classify the information at different times in the same area according to the time information, and then compare the subsequent wind speed, air temperature, water temperature and air pressure. If the data difference is within the given range, discard the data of the previous time and retain the data of the most recent time; if the difference in wind speed, air temperature, water temperature and air pressure is large, retain the data information; finally, classify the retained data again according to the time and location information.

[0044] The data preprocessing module can preprocess the information classified by the data analysis module. For the information with numerical difference within a given range or without difference, the equipment surveying and mapping information belonging to different positions but the same area at the same time is preprocessed, and only the surveying and mapping information of the surveying and mapping equipment at the center of the area is sent; for the information with large difference, all the information is sent, and the information to be sent is Figure 4 The Beidou short message format shown is used for transmission, and the content of the message is the key hydrological elements.

[0045] The integrated surveying and mapping ship can directly receive data information from various surveying and mapping equipment in the nearby sea areas, including information pre-processed by relay surveying and mapping buoys, and process the data directly through the equipment on board; when the integrated surveying and mapping ship is close to the shore-based radar station, the information is directly transmitted to the shore-based radar station and then transmitted to the data center for storage; when far away from the shore and in the deep sea, the information is directly uploaded to the data center via satellite communication; generally, for efficiency reasons, the information is directly transmitted to the data center via satellite communication.

[0046] The shore-based radar station is used to receive and transmit information from surveying and mapping equipment, and can send information.

[0047] The data center can store the information processed by the comprehensive surveying and mapping ship and update it in the database. At the same time, it can also process the surveying and mapping information of each surveying and mapping equipment and save and update the processed information in the database.

[0048] like Figure 3 As shown, a method for processing marine surveying and mapping data collection, the specific steps are as follows:

[0049] S1. The ocean surveying buoy transmits the surveying data to the shore-based radar station via satellite communication; if there is an ocean surveying buoy near the unmanned surveying ship, the nearby data will be transmitted to the nearby ocean surveying buoy first.

[0050] In order to reduce the amount of data transmitted, the unmanned surveying vessel will transmit data via satellite communications before approaching the ocean surveying buoy or relay surveying buoy.

[0051] S2. The ocean surveying buoy transmits the data of the unmanned surveying ship and itself to the relay surveying buoy, and the relay surveying buoy can pre-process the data of the unmanned surveying ship.

[0052] The relay mapping buoy mainly analyzes, classifies, discards and stores the collected data, screens out and discards useless information first, and reduces the amount of data transmission while ensuring data reliability.

[0053] S3. The relay mapping buoy transmits the pre-processed data to the shore-based radar station via satellite communication.

[0054] S4. When there is an integrated surveying ship near the relay surveying buoy, the relay surveying buoy will preferentially transmit the pre-processed data to the integrated surveying ship. The integrated surveying ship will conduct integrated processing on the data of its own unmanned submersible and the data of the relay surveying buoy to obtain the integrated data, which will then be directly transmitted to the shore-based radar station via satellite.

[0055] S5. The shore-based radar station processes the received data and transmits the processed data to the data center. The integrated surveying and mapping ship can connect to the data center and obtain the relevant required data, so that the ocean surveying and mapping data can be updated in real time.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
