Technical Field

[0001] The present invention relates to the field of water area monitoring, and in particular to a reservoir basin monitoring method and system based on dual satellite and 5G communication links. Background Art

[0002] With the intensification of global warming, the occurrence probability of severe weather such as heavy rain and typhoons has gradually increased. In order to cope with the occurrence of floods and artificially adjust rivers, building reservoirs on river basins has become an important means of flood control. Reservoirs play the role of artificial water storage in the dry season and interception regulation in the rainy season. Existing reservoir operations are usually adjusted according to the real-time runoff situation of the basin. However, the above method has a certain time lag, cannot comprehensively and predictively monitor and regulate the reservoir basin, reduces the timeliness and accuracy of monitoring the reservoir basin, and cannot provide a reliable basis for adjusting the operation state of the reservoir. Summary of the Invention

[0069] Please refer to Figure 1 As shown, a reservoir basin monitoring method based on a dual-link of satellite and 5G communication provided by an embodiment of the present application. The reservoir basin monitoring method based on the dual-link of satellite and 5G communication includes:

[0070] Based on the location information of the reservoir, access the satellite link of the remote sensing satellite that remotely photographs the reservoir, so as to obtain the remote sensing satellite image of the area where the reservoir is located; analyze the remote sensing satellite image to determine the runoff state data and river distribution state data of the basin where the reservoir is located;

[0073] Beneficial effects of the above embodiments. The reservoir basin monitoring method based on the dual satellite and 5G communication links connects to the satellite link of the remote sensing satellite that remotely senses and photographs the reservoir based on the location information of the reservoir, obtains the remote sensing satellite image of the area where the reservoir is located, and analyzes therefrom the runoff state data and river distribution state data of the basin where the reservoir is located to globally identify the water flow state of the reservoir basin; based on the runoff state data and river distribution state data, predicts the flow change trend information of the basin where the reservoir is located, and sends control instructions to several corresponding ground monitoring base stations through the 5G communication link to obtain the respective dynamic images of different sub-regions of the basin, realizing the directional monitoring of abnormal areas in the reservoir basin and providing an accurate basis for determining the generation of basin flood peaks; also integrally analyzes the dynamic images of all sub-regions of the basin to obtain the flood peak state and movement information of the basin where the reservoir is located, and combines with the building structure state information of the reservoir to adjust the working state of the reservoir, ensuring that the reservoir can effectively perform water flow scheduling on the basin, improving the safety of the reservoir basin and the reliability of reservoir operation.

[0074] In another embodiment, based on the location information of the reservoir, access the satellite link of the remote sensing satellite that remotely senses and photographs the reservoir, so as to obtain the remote sensing satellite image of the area where the reservoir is located; analyze the remote sensing satellite image to determine the runoff state data and river distribution state data of the basin where the reservoir is located, including:

[0075] Compare the geographical location coordinate information of the reservoir with the remote sensing shooting ground area range information of all remote sensing satellites under the remote sensing satellite group, and screen all remote sensing satellites that can remotely sense and photograph the reservoir; based on the network address information of all the screened remote sensing satellites, access the satellite links corresponding to all the screened remote sensing satellites, so as to obtain the remote sensing satellite image of the area where the reservoir is located;

[0076] Perform dynamic spectral analysis and picture contour recognition on the remote sensing satellite image respectively to obtain the runoff flow state data and river channel distribution state data of the basin where the reservoir is located; wherein, the runoff flow state data includes the flow distribution data of each river in the basin where the reservoir is located along the water flow direction; the river channel distribution state data includes the distribution position data of all river channels in the basin where the reservoir is located and the connection relationship data between them.

[0077] The beneficial effects of the above embodiments are as follows. Reservoirs are usually set up downstream of rivers to regulate the water flow of the rivers in their basins, enabling the reservoirs to store water and reduce flood peaks. The river runoff flow in the basin where the reservoir is located directly affects the operation of the reservoir. Since the river network distribution in the basin where the reservoir is located is usually complex and the basin area is large, in order to comprehensively map the rivers in the reservoir basin, remote sensing satellites are used to photograph and identify the reservoir basin. Specifically, first, compare the geographical location coordinate information of the reservoir (such as longitude and latitude information) with the ground area range information of remote sensing photographs of all remote sensing satellites under the remote sensing satellite group to identify which remote sensing satellites can globally photograph the reservoir basin, so as to screen out all remote sensing satellites that can remotely sense and photograph the reservoir basin; then, based on the network address information of all the screened remote sensing satellites, access the satellite links corresponding to all the screened remote sensing satellites. This satellite link can be directly connected to the remote sensing satellite that remotely senses and photographs the reservoir basin, so as to read the remote sensing image of the area where the reservoir is located in the corresponding remote sensing satellite. Also, since when the river runoff in the basin changes, the reflection spectral distribution on the remote sensing image will also change. By dynamically analyzing the spectrum of the remote sensing satellite image, the runoff flow state data of the reservoir basin can be obtained; in addition, by identifying the picture outline of the remote sensing satellite image, the river channel distribution state data of the reservoir basin can be obtained, so as to comprehensively and accurately identify the flow distribution data, distribution location data of each river in the reservoir basin, and the connection relationship data between them (such as the location of the river confluence), providing a reliable basis for predicting the flow change situation in the reservoir basin in the future.

[0078] In another embodiment, based on the runoff state data and the river distribution state data, predict the flow change trend information of the reservoir basin; based on the flow change trend information, send control instructions to corresponding several ground monitoring base stations through a 5G communication link to obtain the dynamic images of different sub-regions of the basin, including:

[0079] Based on the flow distribution data of each river flowing along the water flow direction in the reservoir basin included in the runoff state data and the distribution location data and the connection relationship data between all the river channels in the reservoir basin included in the river distribution state data, construct a water flow state prediction model of the reservoir basin; based on the water flow state prediction model, determine the flow change trend information of the reservoir basin; wherein, the flow change trend information includes the flow change information of each river in the reservoir basin in the future time period.

[0080] Based on the flow rate change trend information, determine all the river channel positions where sudden increases in flow rate may occur in all the rivers under the reservoir, and send control instructions to several ground monitoring base stations adjacent to all the river channel positions through a 5G communication link, so as to obtain the respective dynamic images of the sub-watershed areas associated with all the river channel positions.

[0081] Beneficial effects of the above embodiments: The runoff flow rates of all the rivers under the reservoir in the watershed are not the same, and there are complex and intertwined water flow convergence relationships among all the rivers under the reservoir in the watershed, which have different impacts on the water flow rate changes of all the rivers under the reservoir in the watershed. In order to accurately predict the water flow rate changes of each river under the reservoir in the watershed, based on the flow rate distribution data of each river under the reservoir in the watershed along the water flow direction included in the runoff state data and the distribution position data of all the river channels under the reservoir in the watershed and the connection relationship data among them included in the river distribution state data, construct a water flow state prediction model for the watershed where the reservoir is located, so that the water flow conditions of each river under the reservoir in the watershed can be accurately and continuously predicted. Then, based on the water flow state prediction model, determine the flow rate change information of all the rivers under the reservoir in the watershed in the future time period, providing a reliable basis for subsequent judgment of whether each river will have a sudden increase in water flow rate. Additionally, based on the flow rate change trend information, identify the water flow rate changes of each river under the reservoir in the watershed for the entire river channel. If the increase rate of the water flow rate in a certain section of the river channel exceeds the preset increase rate threshold within a unit time, it is determined that a sudden increase in flow rate event occurs in this section, and control instructions are sent to several ground monitoring base stations adjacent to all the river channel positions where the sudden increase in flow rate event occurs through a 5G communication link, instructing the ground monitoring base stations to take dynamic pictures of the corresponding river channel positions, obtaining the respective dynamic images of the sub-watershed areas associated with all the river channel positions, so as to take close-up pictures of all the river channel positions where the sudden increase in flow rate event occurs and the sub-watershed areas associated with them, providing sufficient basis for subsequent determination of the occurrence of flood peaks in the watershed.

[0082] In another embodiment, the operation quality of sending control instructions through the 5G communication link is monitored in real time, and it is determined whether there is communication abnormality, including:

[0083] Monitor the operation parameters of the 5G communication link during the sending of control instructions in real time; wherein, the operation parameters include communication bandwidth utilization rate, data transmission rate, and the transmit power of user equipment.

[0084] Obtain the operation evaluation parameters of the 5G communication link by using the communication bandwidth utilization rate, data transmission rate, and the transmit power of user equipment; wherein, the operation evaluation parameters of the 5G communication link are obtained through the following formula:

[0085]

[0086] Among them, J represents the operation evaluation parameter of the 5G communication link; B represents the current communication bandwidth utilization rate of the 5G communication link; ε represents a preset minimum constant used to prevent the denominator from being zero; P represents the transmission power of the corresponding user equipment of the 5G communication link at present; P0 represents the expected transmission power of the user equipment; δ represents the width of the control distribution; R represents the evaluation parameter corresponding to the data transmission rate; Q represents the signal quality parameter;

[0087] Among them, the evaluation parameter corresponding to the data transmission rate is obtained through the following formula:

[0088]

[0089] Among them, R represents the evaluation parameter corresponding to the data transmission rate; n represents the number of unit times for data transmission of the 5G communication link, and the unit time is 1s; V i represents the data transmission rate corresponding to the i-th unit time; V p represents the average value of the data transmission rates corresponding to n unit times; B i represents the communication bandwidth utilization rate corresponding to the i-th unit time; B p represents the average value of the communication bandwidth utilization rates corresponding to n unit times; Q represents the signal quality parameter, and the signal quality parameter is obtained through the following formula:

[0090]

[0091] Among them, Q represents the signal quality parameter; n represents the number of unit times for data transmission of the 5G communication link, and the unit time is 1s; P i represents the transmission power of the user equipment corresponding to the i-th unit time; P0 represents the expected transmission power of the user equipment; B i represents the communication bandwidth utilization rate corresponding to the i-th unit time; B0 represents the lowest communication bandwidth utilization rate that can meet the communication quality requirements of the 5G communication link;

[0092] Compare the operation evaluation parameter of the 5G communication link with the preset operation evaluation parameter threshold;

[0093] When the operation evaluation parameter of the 5G communication link is lower than the preset operation evaluation parameter threshold, it is determined that there is a communication anomaly during the control instruction sending process of the 5G communication link, and a communication anomaly alarm is given.

[0094] The beneficial effects of the above embodiments are as follows. By continuously monitoring the operating parameters of the 5G communication link during the transmission of control commands (such as communication bandwidth utilization rate, data transmission rate, and transmit power of user equipment), the operating status of the link can be obtained immediately. This real-time monitoring mechanism allows the system to quickly respond to any potential problems, thereby improving the reliability and stability of the communication system. The proposed operating evaluation parameter J is a comprehensive index that takes into account multiple factors such as communication bandwidth utilization rate, data transmission rate, transmit power of user equipment, and signal quality. Through this comprehensive evaluation, a more comprehensive understanding of the overall performance of the 5G communication link can be achieved, rather than just the advantages and disadvantages of a single parameter. By comparing the operating evaluation parameter of the 5G communication link with a preset threshold of the operating evaluation parameter, it is possible to accurately determine whether there is a communication anomaly. This determination method avoids the limitations of judgment based on a single parameter or a simple threshold, improving the accuracy and reliability of anomaly detection. When a communication anomaly is detected, the system will issue a communication anomaly alarm to promptly notify relevant personnel for handling. This prevention and maintenance mechanism helps reduce the occurrence of communication failures, lower maintenance costs, and ensure the continuous and stable operation of the communication system.

[0108] In another embodiment, the remote sensing image acquisition module is used to access the satellite link of the remote sensing satellite that conducts remote sensing photography of the reservoir based on the location information of the reservoir, so as to obtain the remote sensing satellite image of the area where the reservoir is located, including:

[0109] Compare the geographical location coordinate information of the reservoir with the remote sensing photography ground area range information of all remote sensing satellites under the remote sensing satellite group, and screen all remote sensing satellites that can conduct remote sensing photography of the reservoir; based on the network address information of all the screened remote sensing satellites respectively, access the satellite links corresponding to all the screened remote sensing satellites, so as to obtain the remote sensing satellite image of the area where the reservoir is located;

[0110] The remote sensing image analysis module is used to analyze the remote sensing satellite image to determine the runoff state data and river distribution state data of the watershed where the reservoir is located, including:

[0111] Conduct dynamic spectral analysis and picture contour recognition on the remote sensing satellite image respectively to obtain the runoff flow state data and river channel distribution state data of the watershed where the reservoir is located; among them, the runoff flow state data includes the flow distribution data of each river in the watershed where the reservoir is located along the water flow direction; the river channel distribution state data includes the distribution position data of all river channels in the watershed where the reservoir is located and the connection relationship data between them.

[0112] The beneficial effects of the above embodiments are as follows. Reservoirs are usually set up downstream of rivers and are used to regulate the water flow of the rivers in their basins, enabling the reservoirs to store water and reduce flood peaks. The river runoff flow of the river in the reservoir basin directly affects the operation of the reservoir. Since the river network distribution in the reservoir basin is usually complex and the basin area is large, in order to comprehensively map the rivers in the reservoir basin, remote sensing satellites are used to photograph and identify the reservoir basin. Specifically, first, the geographical location coordinate information of the reservoir (such as longitude and latitude information) is compared with the remote sensing photographing ground area range information of all remote sensing satellites under the remote sensing satellite group to identify which remote sensing satellites can globally photograph the reservoir basin, so as to screen out all remote sensing satellites that can remotely sense and photograph the reservoir basin. Then, based on the network address information of all the screened remote sensing satellites, the satellite links corresponding to all the screened remote sensing satellites are accessed. This satellite link can directly connect to the remote sensing satellite that remotely senses and photographs the reservoir basin, so as to read the remote sensing image of the area where the reservoir is located in the corresponding remote sensing satellite. Moreover, since when the river runoff in the basin changes, the reflection spectrum distribution on the remote sensing image will also change. By dynamically analyzing the spectrum of the remote sensing satellite image, the runoff flow state data of the reservoir basin can be obtained. In addition, by identifying the picture contour of the remote sensing satellite image, the river channel distribution state data of the reservoir basin can be obtained, so as to comprehensively and accurately identify the flow distribution data, distribution position data of each river in the reservoir basin, and the connection relationship data between them (such as the location of the river confluence), providing a reliable basis for predicting the flow change situation in the reservoir basin in the future.

[0113] In another embodiment, the basin flow trend prediction module is used to predict the flow change trend information of the reservoir basin based on the runoff state data and the river distribution state data, including:

[0114] Based on the flow distribution data of each river in the reservoir basin along the water flow direction included in the runoff state data and the distribution position data and the connection relationship data between all the river channels in the reservoir basin included in the river distribution state data, a water flow state prediction model of the reservoir basin is constructed; based on the water flow state prediction model, the flow change trend information of the reservoir basin is determined; wherein, the flow change trend information includes the flow change information of each river in the reservoir basin in the future time period.

[0115] The ground monitoring and control module is used to send control commands to corresponding several ground monitoring base stations through a 5G communication link based on the flow change trend information, so as to obtain the dynamic images of different sub-regions of the basin, including:

[0116] Based on the flow rate change trend information, determine all river channel positions where sudden flow rate increases may occur in all rivers under the reservoir, and send control instructions to several ground monitoring base stations adjacent to all river channel positions through a 5G communication link, so as to obtain the respective dynamic images of the sub-watershed areas associated with all river channel positions.

[0117] The beneficial effects of the above embodiments are as follows. The runoff flow rates of all rivers under the reservoir in the basin where the reservoir is located are not the same, and there are complex and intertwined water flow convergence relationships among all rivers under the reservoir in the basin where the reservoir is located, which have different effects on the water flow rate changes of all rivers under the reservoir in the basin where the reservoir is located. In order to accurately predict the water flow rate changes of each river under the reservoir in the basin where the reservoir is located, based on the flow rate distribution data of each river under the reservoir in the basin where the reservoir is located along the water flow direction included in the runoff state data and the distribution position data of all river channels under the reservoir in the basin where the reservoir is located and the connection relationship data among them included in the river distribution state data, construct a water flow state prediction model for the basin where the reservoir is located, so that the water flow conditions of each river under the reservoir in the basin where the reservoir is located can be accurately and continuously predicted. Then, based on the water flow state prediction model, determine the flow rate change information of all rivers under the reservoir in the basin where the reservoir is located in the future time period, providing a reliable basis for subsequent judgment of whether the water flow rate of each river will suddenly increase. Moreover, based on the flow rate change trend information, identify the water flow rate changes of each river under the reservoir in the basin where the reservoir is located throughout the entire river channel. If the increase rate of the water flow rate in a certain section of the river channel exceeds the preset increase rate threshold within a unit time, it is determined that a sudden flow rate increase event occurs in this section, and control instructions are sent to several ground monitoring base stations adjacent to all river channel positions where the sudden flow rate increase event occurs through a 5G communication link, instructing the ground monitoring base stations to perform dynamic shooting on the corresponding river channel positions, obtaining the respective dynamic images of the sub-watershed areas associated with all river channel positions, so as to perform close-range shooting on all river channel positions where the sudden flow rate increase event occurs and the sub-watershed areas associated with them, providing sufficient basis for subsequent determination of the occurrence of flood peaks in the basin.

[0118] In another embodiment, the operation quality of the 5G communication link for sending control instructions is monitored in real time, and it is determined whether there is communication abnormality, including:

[0119] Monitor the operation parameters of the 5G communication link during the process of sending control instructions in real time; wherein, the operation parameters include communication bandwidth utilization rate, data transmission rate, and the transmission power of user equipment.

[0120] Obtain the operation evaluation parameters of the 5G communication link by using the communication bandwidth utilization rate, data transmission rate, and the transmission power of user equipment; wherein, the operation evaluation parameters of the 5G communication link are obtained through the following formula:

[0123] Among them, the evaluation parameter corresponding to the data transmission rate is obtained through the following formula:

[0124]

[0125] Among them, R represents the evaluation parameter corresponding to the data transmission rate; n represents the number of unit times for data transmission of the 5G communication link, and the unit time is 1s; V i represents the data transmission rate corresponding to the i-th unit time; V p represents the average value of the data transmission rates corresponding to n unit times; B i represents the communication bandwidth utilization rate corresponding to the i-th unit time; B p represents the average value of the communication bandwidth utilization rates corresponding to n unit times; Q represents the signal quality parameter, and the signal quality parameter is obtained through the following formula:

[0126]

[0127] Among them, Q represents the signal quality parameter; n represents the number of unit times for data transmission of the 5G communication link, and the unit time is 1s; P i represents the transmission power of the user equipment corresponding to the i-th unit time; P0 represents the expected transmission power of the user equipment; B i represents the communication bandwidth utilization rate corresponding to the i-th unit time; B0 represents the lowest communication bandwidth utilization rate that can meet the communication quality requirements of the 5G communication link.

[0128] Compare the operation evaluation parameter of the 5G communication link with a preset operation evaluation parameter threshold.

[0129] When the operation evaluation parameter of the 5G communication link is lower than the preset operation evaluation parameter threshold, it is determined that there is a communication anomaly during the control instruction sending process of the 5G communication link, and a communication anomaly alarm is given.

[0130] The beneficial effects of the above embodiments are as follows. By real-time monitoring of the operating parameters of the 5G communication link during the transmission of control instructions (such as communication bandwidth utilization, data transmission rate, and transmission power of user equipment), the operating state of the link can be immediately obtained. This real-time monitoring mechanism allows the system to quickly respond to any potential problems, thereby improving the reliability and stability of the communication system. The proposed operating evaluation parameter J is a comprehensive index that takes into account multiple factors such as communication bandwidth utilization, data transmission rate, transmission power of user equipment, and signal quality. Through this comprehensive evaluation, a more comprehensive understanding of the overall performance of the 5G communication link can be achieved, rather than just the advantages and disadvantages of a single parameter. By comparing the operating evaluation parameter of the 5G communication link with a preset operating evaluation parameter threshold, it is possible to accurately determine whether there is a communication anomaly. This determination method avoids the limitations of judgment based on a single parameter or a simple threshold, improving the accuracy and reliability of anomaly detection. When a communication anomaly is detected, the system will issue a communication anomaly alarm to promptly notify relevant personnel for handling. This prevention and maintenance mechanism helps reduce the occurrence of communication failures, lower maintenance costs, and ensure the continuous and stable operation of the communication system. Through real-time monitoring and anomaly determination, the system can promptly detect and solve problems in the communication link, thereby ensuring the accurate and timely transmission of control instructions. This is of great significance for improving the user experience and ensuring service quality, especially in application scenarios with high real-time requirements (such as autonomous driving, telemedicine, etc.). This technical solution is not only applicable to the current 5G communication system but can also be adaptively adjusted according to the development of future communication technologies.

Also, based on the flood peak state and movement information, determine the water pressure acting force information on the reservoir when the flood peak arrives at the reservoir, and combine it with the building structure state information of the reservoir to judge whether the reservoir can completely intercept the flood peak while ensuring the safety of its own structure (i.e., completely intercept the flood peak inside the reservoir). If the flood peak can be completely intercepted, control the outlet gate of the reservoir to perform a closing operation so that the reservoir completely intercepts the flood peak and does not discharge flood downstream; if the flood peak cannot be completely intercepted, adjust the opening duration and opening amplitude of the outlet gate of the reservoir based on the flood peak formation time and the flood peak flow rate so that the reservoir can partially intercept the flood peak, thereby achieving the maximum reduction of the flood peak and ensuring the safety of the basin where the reservoir is located.
