Description

Technical Field

[0001] The invention belongs to the technical field of ocean monitoring, and in particular relates to a buoy positioning monitoring and early warning system. Background Art

[0002] Ocean observation is crucial for understanding climate change, protecting marine ecosystems, warning of natural disasters, monitoring marine pollution and ensuring shipping safety. Among the many marine observation devices, buoys are a widely used key device, which are usually divided into drifting buoys and anchored buoys. Drifting buoys are devices that drift with the current in an unfixed position. They can drift freely in a specific sea area and collect various marine data. Since drifting buoys do not have a fixed position, their position needs to be monitored to ensure that they are within the target observation sea area; accurate positioning information is required for recovery, otherwise these devices may not be accurately found and recovered.

[0003] Existing buoy systems usually integrate longitude and latitude information into observation data, and the positioning monitoring and early warning function design lacks automation. In actual operation, many steps rely on manual data acquisition and comparison with the target observation sea area to determine whether the buoy is in the target sea area. This not only increases the workload, but also fails to guarantee the real-time nature of the data. In addition, when faced with situations such as ship collisions and wind and wave impacts that may cause the buoy to deviate from the predetermined position, the existing system lacks a more efficient alarm mechanism, making it difficult to notify operators in a timely manner. Summary of the invention

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention and implement it, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the scope of protection of the present invention.

[0016] Example The present invention provides a buoy positioning monitoring and early warning system, such as Figure 1 As shown in the figure, it includes an onboard system and a shore-based early warning system. Through the collaborative work of the two, the real-time monitoring and abnormal warning of the position and status of the ocean buoy can be realized. The offshore buoy is equipped with advanced hardware modules, which can communicate with satellites in two directions to obtain the real-time position coordinates of the buoy. This system not only improves the real-time nature of the buoy data, but also ensures the reliability of data transmission. When the buoy position changes, the satellite will transmit the positioning information in the form of an email to the mailbox bound to the buoy through the cloud server.

[0017] The device onboard system consists of multiple modules, the specific structure is as follows Figure 2 As shown. The Iridium module includes the Iridium antenna module and the Iridium processing module. The Iridium antenna module is responsible for sending and receiving satellite signals to ensure stable communication between the buoy and the shore-based early warning system. The Iridium processing module communicates closely with the main control board, which is the main control module, and is responsible for receiving and sending various data and positioning information. With the help of the satellite network, this module ensures that the data collected by the buoy can be transmitted to the shore-based early warning system in real time and efficiently, thereby supporting global monitoring and research needs.

[0018] The functions of the main control board software cover multiple key modules, including encoding and decoding module, data storage module, timeout retransmission module, time synchronization module and expansion interface module. The encoding and decoding module is responsible for decoding the received command information and packaging the buoy's positioning information and the data collected by the sensor into a protocol format for sending. It improves the degree of automation of data processing and ensures the accuracy and timeliness of information transmission. In the case of poor signal quality, the timeout retransmission module will temporarily store the data to be sent and retransmit it when the conditions improve to ensure the integrity and reliability of the data. It avoids data loss caused by signal interruption and ensures the continuity of buoy monitoring. The data storage module uses SD mode to access data in the SD card. The module can still record key data when data transmission is not smooth. It is convenient for subsequent upload to ensure that data will not be lost due to temporary communication failures. The time synchronization module performs pulse synchronization through the onboard crystal oscillator to ensure the time consistency of each module within the system. Accurately mark the time of the collected data and events, thereby improving the accuracy of subsequent data analysis and processing. The expansion interface module reserves multiple RS232 protocol serial ports to support the mounting of different observation equipment. This flexible design allows users to easily expand system functions according to their needs and connect a variety of sensors or other devices, greatly enhancing the adaptability and scalability of the device. Through the close collaboration of these modules, the onboard system of the device provides comprehensive and reliable support for real-time monitoring and data processing of ocean buoys, ensuring that it can operate efficiently in various environments.

[0019] The shore-based early warning system includes an initialization module, a setting module, a judgment module and an alarm module.

[0020] The initialization module first initializes the unique identifier of the Iridium antenna module. The module identifier of each different ocean observation device is unique, ensuring that the system can accurately identify and manage each device. After completing the identifier setting, the system will perform a handshake authentication.

[0021] After authentication, the setting module allows the user to set the target observation area. According to the actual mission requirements, the operator can flexibly adjust the boundaries and range of the observation area to adapt to different monitoring requirements and environmental conditions. The system then logs in to the mailbox bound to the Iridium module through the IMAP protocol. The login process requires confirmation of all relevant settings, including the correct email address and connection parameters. If the login is unsuccessful, the system will prompt to check whether the onboard Iridium identification is correct and ensure that the identification is consistent with the server record to avoid communication failure due to recognition errors; if the login is successful, the system downloads the data from the mailbox, parses the data, and automatically detects whether the buoy is within the target observation area. Monitor the dynamic state of the buoy in real time.

[0022] After decoding the acquired positioning data, the system will quickly analyze whether the buoy is located in the preset target observation area by comparing the real-time positioning data with the preset activity range. The judgment module also has the ability to analyze based on historical data, and predict the drift trajectory of the buoy according to the positioning information obtained in the previous times. This prediction function helps staff understand the possible drift direction and speed of the buoy through past positioning data and environmental factors, thereby providing a basis for formulating response strategies. Once the system detects that the buoy has drifted out of the target area, the alarm module will be activated immediately. This mechanism can send alarm notifications to relevant personnel in a timely manner through multiple channels, such as through email, fax or other user-defined communication methods, to ensure that the information can be quickly conveyed to those who need it. This real-time alarm notification mechanism can not only help staff to understand the abnormal status of the buoy in a timely manner, but also prompt them to take necessary countermeasures quickly to reduce potential risks and losses. The flow chart of the shore-based early warning system is as follows Figure 3 shown.

[0023] It should be noted that the above-described specific implementations can enable those skilled in the art to more fully understand the invention, but do not limit the invention in any way. Simple changes or equivalent replacements of the technical solutions that can be obviously obtained by those skilled in the art within the technical scope disclosed in the present invention all belong to the protection scope of the present invention.
