Marine monitoring systems such as buoys, submerged buoys, automatic stations and various parameter monitors generally refer to the measurement of multiple meteorological elements such as wind speed, wind direction, temperature, humidity, air pressure, ocean currents, etc. in a certain sea area. Since the ocean conditions in each sea area change in real time, it is necessary to ensure that the ocean monitoring system can always be in good working condition.

[0003] However, in the existing monitoring technology, it is impossible to supervise and analyze the monitoring status of the monitoring equipment, which leads to an increase in the risk of abnormal monitoring, and it is impossible to verify and supervise the feedback information of the monitoring equipment on the visualization equipment, thereby reducing the reliability and accuracy of the information feedback of the visualization equipment, and at the same time reducing the visual feedback effect of the information, which is not conducive to intuitively understanding the monitoring status of the monitoring equipment, and it is impossible to supervise the visual picture, thereby reducing the visual integrity of the information and the visual monitoring effect;

[0050] See also Figure 1 to Figure 2 As shown, the present invention is a marine water monitoring system based on data visualization, including a visual monitoring platform, a monitoring and evaluation unit, a visual supervision unit, a data verification unit, an information evaluation unit and a display response unit, the visual monitoring platform is connected to the monitoring and evaluation unit in a one-way communication, the monitoring and evaluation unit is connected to the visual supervision unit and the display response unit in a one-way communication, the visual supervision unit is connected to the data verification unit and the information evaluation unit in a one-way communication, and the data verification unit and the information evaluation unit are connected to the display response unit in a one-way communication;

[0051] When the visual monitoring platform generates an operation management instruction, it sends the operation management instruction to the monitoring and evaluation unit. After receiving the operation management instruction, the monitoring and evaluation unit immediately collects the monitoring performance data of the monitoring equipment and performs information effectiveness supervision and evaluation analysis on the monitoring performance data to understand the operation status and information effectiveness of the monitoring equipment, so as to achieve accurate management of the monitoring equipment and improve the effectiveness of the monitoring information. The specific information effectiveness supervision and evaluation analysis process is as follows:

[0052] Set the monitoring cycle and set it as the time threshold. Divide the time threshold into i sub-time periods, where i is a natural number greater than zero. Obtain the monitoring performance data of the monitoring equipment in the target sea area in each sub-time period. The monitoring performance data includes the transmission stability value and the monitoring risk value. The transmission stability value and the monitoring risk value are labeled CWi and JFi respectively. Substitute the transmission stability value CWi and the monitoring risk value JFi into the formula The data risk assessment coefficient of each sub-time period is obtained, where a1 and a2 are the preset proportional factor coefficients of the transmission stability value CWi and the monitoring risk value JFi respectively. The proportional factor coefficient is used to correct the deviation of various parameters in the formula calculation process, so as to make the calculation result more accurate. a3 is the preset correction factor coefficient. a1, a2 and a3 are all greater than zero. Ci is the data risk assessment coefficient of each sub-time period, and then the maximum and minimum values ​​in the data risk assessment coefficient Ci are obtained, and the difference between the maximum and minimum values ​​in the data risk assessment coefficient Ci is set as the data risk span coefficient. The data risk span coefficient is compared and analyzed with the preset data risk span coefficient threshold value stored in the internal input:

[0053] If the ratio between the data risk span coefficient and the preset data risk span coefficient threshold is less than 1, a normal signal is generated and sent to the visual supervision unit;

[0054] If the ratio between the data risk span coefficient and the preset data risk span coefficient threshold is greater than or equal to 1, a risk signal is generated, and the normal signal and the risk signal are sent to the display response unit. After receiving the normal signal and the risk signal, the display response unit immediately marks the monitoring device corresponding to the normal signal as green, and the monitoring device corresponding to the risk signal as red, so as to intuitively understand the monitoring status of each monitoring device, and then timely manage and maintain it to achieve the safety and stability of monitoring;

[0055] In the embodiment of the present invention, the transmission stability value indicates the proportion of the duration corresponding to the preset data transmission amount per unit time of the monitoring device in the sub-time period. It should be noted that the monitoring risk of the monitoring device is understood from the perspective of the data transmission stability of the monitoring device, so as to achieve timely transmission.

[0056] In the embodiment of the present invention, the monitoring risk value indicates that the value corresponding to the state parameter of the monitoring device is greater than the duration of the overlap corresponding to the preset threshold value, and the state parameter includes the temperature rise rate, the vibration amplitude, etc. It should be noted that the failure risk of the monitoring device is understood from the perspective of the operating performance characteristics of the monitoring device to ensure the normal operation of the monitoring device, thereby helping to ensure the validity of the monitoring data;

[0057] When a normal signal is generated, that is, under the premise that the monitoring equipment is operating normally, the visual supervision unit performs analysis from the visual angle of the monitoring equipment, that is, the visual supervision unit performs information feedback matching supervision analysis to understand whether the actual display of the monitoring equipment in the visualization equipment corresponds to the feedback, so as to improve the visual accuracy and information reliability of the visualization equipment. The specific information feedback matching supervision analysis process is as follows:

[0058] The number and number of monitoring devices marked in red in the visualization device and the number and number of monitoring devices corresponding to the risk signal are actually obtained within the time threshold. If the number of monitoring devices marked in red in the visualization device is the same as the number of monitoring devices corresponding to the risk signal, and the numbers corresponding to the monitoring devices marked in red correspond to the numbers corresponding to the monitoring devices corresponding to the risk signal, a matching instruction is generated;

[0059] The number and number of monitoring devices marked in green in the visualization device and the number and number of monitoring devices corresponding to normal signals within the time threshold are actually obtained. If the number of monitoring devices marked in green in the visualization device is the same as the number of monitoring devices corresponding to normal signals, and the numbers of monitoring devices marked in green correspond to the numbers of monitoring devices corresponding to normal signals, then a corresponding instruction is generated, and the matching instruction and the corresponding instruction are further analyzed:

[0060] If the matching instruction and the corresponding instruction are generated at the same time, a visual standard signal is obtained;

[0061] If the matching instruction and the corresponding instruction are not generated at the same time, a visual deviation signal is obtained, and the visual standard signal and the visual deviation signal are sent to the display response unit through the data verification unit. After receiving the visual standard signal and the visual deviation signal, the display response unit immediately displays the preset warning text corresponding to the visual standard signal and the visual deviation signal, so as to manage and adjust the visualization equipment and the monitoring equipment according to the feedback to ensure the authenticity and accuracy of the visual data in the visualization equipment. Example

[0062] After the visual standard signal is generated, the data changes of the monitoring device in the visualization device are further supervised, that is, the data verification unit collects the transmission data of the monitoring device and performs visual timeliness supervision evaluation and analysis on the transmission data to understand the timeliness of the connection transmission between the visualization device and the monitoring device. The specific visual timeliness supervision evaluation and analysis process is as follows:

[0063] The change time of the monitoring data corresponding to the monitoring device in the visualization device within the time threshold is obtained, and at the same time, the corresponding time when the target monitoring device starts to transmit the monitoring data within the time threshold is obtained, and the difference between the change time of the monitoring data corresponding to the target monitoring device in the visualization device and the corresponding time when the target monitoring device starts to transmit the monitoring data is set as the transmission duration, and m transmission durations within the time threshold are obtained, where m is a natural number greater than zero, and a rectangular coordinate system is established with the number of transmission durations as the X-axis and the transmission duration as the Y-axis, and a transmission duration curve is drawn by drawing points, and the maximum peak value and the minimum trough value in the transmission duration curve are obtained, and the difference between the maximum peak value and the minimum trough value in the transmission duration curve is set as the display deviation coefficient. It should be noted that the display deviation coefficient is a data embodiment that reflects the data flow between the target monitoring device and the visualization device, that is, the transmission timeliness between the target monitoring device and the visualization device is understood from the perspective of transmission, so as to optimize the connection between the target monitoring device and the visualization device, so as to ensure the timeliness and accuracy of the visualization device data display;

[0064] Compare and analyze the displayed deviation coefficient with the preset display deviation coefficient threshold value stored in the internal storage:

[0065] If the ratio between the display deviation coefficient and the preset display deviation coefficient threshold is less than 1, any signal is generated;

[0066] If the ratio between the display deviation coefficient and the preset display deviation coefficient threshold is greater than or equal to 1, a management signal is generated and sent to the display response unit. After receiving the management signal, the display response unit immediately marks the monitoring device corresponding to the management signal with text as "connection optimization" so as to intuitively understand the timeliness of data transmission of the monitoring device;

[0067] After generating the visual standard signal, the information evaluation unit further analyzes the data information integrity of the monitoring device in the visualization device so as to intuitively understand the data information integrity of the monitoring device, that is, collects the display risk data of the visualization device, and performs visual information integrity supervision evaluation and analysis on the display risk data to understand the visual information risk situation. The specific visual information integrity supervision evaluation and analysis process is as follows:

[0068] The display risk data of the visualization device within the time threshold is obtained. The display risk data includes the screen abnormality value and the screen deviation value. The screen abnormality value and the screen deviation value are compared and analyzed with the preset screen abnormality value threshold and the preset screen deviation value threshold that are recorded and stored internally:

[0069] If the image abnormality value is less than the preset image abnormality value threshold, and the image deviation value is less than the preset image deviation value threshold, no signal is generated;

[0070] If the image abnormal value is greater than or equal to the preset image abnormal value threshold, or the image deviation value is greater than or equal to the preset image deviation value threshold, an abnormal signal is generated and sent to the display response unit. After receiving the abnormal signal, the display response unit immediately displays the preset warning text corresponding to the abnormal signal, that is, the preset warning text corresponding to the abnormal signal is "display management", so as to reduce the risk of missing information of the visualization device, thereby helping to improve the integrity of the monitoring information of the visualization device;

[0071] In the embodiment of the present invention, the screen abnormality value indicates the total duration of abnormal performance of the screen, and the abnormal performance includes jitter, wave, etc. It should be noted that the abnormal performance may include but is not limited to: jitter, wave, it can be understood that this example is only used to illustrate the abnormal performance, in the actual application process, the server can be preset to obtain different abnormal performance;

[0072] In the embodiment of the present invention, the image deviation value represents the product value obtained by multiplying the duration corresponding to the surface loss and the image loss frequency corresponding to the image loss in the image feature video of the visualization device by the set error weight factor. It should be noted that the information integrity risk of the visualization device is understood from the perspective of image loss, so as to improve the integrity of the target sea area monitoring information;

[0073] In summary, the present invention performs information validity supervision, evaluation and analysis on the monitoring performance data of the monitoring equipment to understand the operation status and information validity of the monitoring equipment, so as to achieve accurate management of the monitoring equipment and improve the validity of the monitoring information. Under the premise that the monitoring equipment is normal, information feedback matching supervision and analysis is performed through information feedback to understand whether the actual display status of the monitoring equipment in the visualization device corresponds to the feedback status, so as to improve the visual accuracy and information reliability of the visualization device. Under the matching premise, the transmission data is deeply supervised, evaluated and analyzed for visual timeliness, that is, the transmission timeliness between the target monitoring device and the visualization device is understood from the perspective of transmission, so as to optimize the connection between the target monitoring device and the visualization device, so as to ensure the timeliness and accuracy of the data displayed by the visualization device. At the same time, the data information integrity of the monitoring device in the visualization device is further analyzed, so as to intuitively understand the data information integrity of the monitoring device, that is, the display risk data of the visualization device is collected, and the display risk data is supervised, evaluated and analyzed for visual information integrity, so as to reduce the risk of missing information of the visualization device, thereby helping to improve the monitoring information integrity and visual monitoring effect of the visualization device.

[0074] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0075] The above formulas are obtained by collecting a large amount of data for software simulation and selecting a formula that is close to the actual value. The coefficients in the formula are set by technical personnel in this field according to actual conditions. The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited to this. Any technical personnel familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, make equivalent replacement or change, which should be covered within the protection scope of the present invention.
