[0002] In recent years, with the development of offshore wind power technology, my country's offshore wind power installed capacity has increased day by day. However, at present, offshore wind power projects are still concentrated in the water depth of about 60 meters offshore. The offshore mobile platform is a major basic facility for the installation and maintenance of offshore wind power, and is the base for offshore production operations and life.

[0003] On the one hand, when the offshore mobile platform goes out to sea for production operations, it needs to face a very harsh natural environment, and various unexpected situations, especially those that affect the safety of the platform, are constantly encountered. However, due to the weak or even no signal in the offshore environment, the land monitoring center cannot grasp the platform operation status in real time, effectively, and systematically; on the other hand, when the offshore mobile platform is docked on the shore for repairs, the platform will be unattended for a long time. Utility Model Content

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, unless otherwise clearly specified and limited, "connection", "fixation" and the like should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, or it can be an electrical connection or a network connection, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1 As shown, a safety monitoring system based on an offshore mobile platform comprises a sensor measuring instrument 1, an offshore data processing device 2, a Beidou short message sending device 3 installed on the offshore mobile platform, and a Beidou short message receiving device 4, a land data processing device 5, a data server 6 and a data monitoring center 7 installed on land, wherein the input end of the offshore data processing device 2 is connected to the sensor measuring instrument 1, the output end of the offshore data processing device 2 is connected to the input end of the Beidou short message sending device 3, the output end of the Beidou short message sending device 3 is network-connected to the input end of the Beidou short message receiving device 4, the output end of the Beidou short message receiving device 4 is connected to the input end of the land data processing device 5, the output end of the land data processing device 5 is connected to the input end of the data server 6, and the output end of the data server 6 is connected to the data monitoring center 7.

[0021] The sensor measuring instrument 1 is used to measure the relevant physical quantities, visual images, etc. of the operating status of the offshore mobile platform, and send the measured raw data to the offshore data processing device 2. The sensor measuring instrument 1 can be a strain sensor, a tilt acceleration sensor, a low-power camera, a serial port camera, a smoke sensor, etc., based on one or more combinations of communication protocols such as RS485 / RS232 / switch quantity, etc.

[0022] The offshore data processing device 2 is used to receive the raw data sent by the sensor measuring instrument 1, and perform sampling analysis and edge computing on the raw data, convert the measured raw data according to the specific format required by the data server 6, and package and send it to the Beidou short message sending device 3. The Beidou short message sending device 3 will send the parsed data to the Beidou short message receiving device 4 in a transparent manner.

[0023] After receiving the data from the Beidou short message sending device 3, the Beidou short message receiving device 4 transmits the data to the land data processing device 5, which processes the data and sends the data to the data server 6 through the 4G wireless network in accordance with the MQTT protocol. The data monitoring center 7 obtains data from the data server 6 by subscription and displays it on the front end.

[0024] After receiving the sensor data, the data monitoring center 7 displays it visually through curves, columns and other graphics, and compares it with the safety value. If an early warning is triggered, it is finally determined whether there is a safety risk by manually comparing photos.

[0025] As an optional embodiment, for some areas where 4G signals exist, such as near a dock during a rest period at the shore, some sensor measuring instruments 1 can send data directly to the data server 6 through the 4G network in addition to sending data through the Beidou satellite.

[0026] As an optional embodiment, the system further includes a storage battery 8 and a wind-solar complementary power supply module 9, and the storage battery and the wind-solar complementary power supply module are respectively connected to the sensor measuring instrument 1.

[0027] The wind-solar complementary power supply module 9 generates electricity using wind energy and solar energy. At night or when the solar panels and wind turbines cannot provide sufficient power, the battery 8 outputs power to the system, which can ensure 24-hour power supply without the need for external power supply.

[0028] The data transmitted in the above system is mainly divided into three categories: one is equipment status information, such as battery voltage, solar panel voltage, 4G signal, sensor status, etc.; the second is various physical quantity data, which depends on various sensors, and can be stress, tilt, acceleration, speed and other physical quantities; the third is image data in JPEG, DDS and other formats. Because the Beidou short message communication rate is limited, the data sent at a single time does not exceed 78 bytes. Class I and Class II data will be sent directly. As for the third type of image data, because the data volume is large, the offshore data processing device 2 will split the image into multiple data packets and send them to the Beidou short message sending device 3 in batches. The land data processing device 5 will then integrate and restore the image data.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
