Based on the hardware structure, the invention provides various embodiments of the water level early warning method.

The invention provides a water level early warning method. Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the water level early warning method according to the present invention, in this embodiment, the water level early warning method according to the present invention is applied to the terminal device, and the water level early warning method according to the present invention includes:

step S10, acquiring a first real-time distance between a horizontal plane and electrical equipment of the photovoltaic power station;

the method comprises the steps that in the process of flood early warning of the photovoltaic power station, the terminal equipment is used for constructing a first real-time distance between any electric equipment forming the photovoltaic power station by acquiring a horizontal plane distance.

It should be noted that, in the present embodiment, the electrical equipment of the photovoltaic power station includes, but is not limited to, a photovoltaic panel and a junction box, wherein the junction box is generally installed at a middle position of the photovoltaic panel. In addition, in the photovoltaic power station, a plurality of distance sensors are installed on each electrical equipment for constructing and forming the photovoltaic power station, and the distance sensors can acquire and calibrate the real-time distance between a horizontal plane and the lowest edge of the electrical equipment in real time.

Further, in a possible embodiment, the step S10 may include:

step S101, acquiring first real-time distances from the horizontal plane to the electrical equipment, which are acquired by the distance sensors in real time.

The method comprises the steps that communication connection is established between terminal equipment and distance sensors installed on each electrical equipment for constructing a photovoltaic power station in advance, therefore, the distance sensors respectively acquire first real-time distances between a horizontal plane and the lowest edge of the electrical equipment in real time according to set real-time distances, then the acquired first real-time distances are reported to the terminal equipment through the communication connection in real time, and the terminal equipment receives the first real-time distances to acquire the first real-time distances.

Further, in another possible embodiment, after step S101, the water level early warning method of the present invention may further include:

step S102, storing each real-time distance into a preset database in a related manner according to the time when each distance sensor acquires each real-time distance in real time.

It should be noted that, in this embodiment, the preset database may be a dedicated storage space opened in a built-in local storage space for the terminal device, or the preset database may also be a dedicated storage space opened in an external entity storage space or a cloud storage space for the terminal device.

After receiving the first real-time distances reported by the distance sensors, the terminal device stores the first real-time distances in the special storage space by taking the time as an index condition according to the time when the distance sensors synchronously report and acquire the first real-time distances. Therefore, in the process that the terminal equipment carries out flood early warning on a horizontal plane through a photovoltaic power station built by piling, the time which is short from the current time can be used as an index, and therefore the first real-time distance acquired by each distance sensor at the time in real time is acquired in the storage space.

Step S20, predicting a first rising speed of the horizontal plane by a trend prediction algorithm by using the first real-time distance;

after the terminal equipment obtains the first real-time distance between the horizontal plane and the electrical equipment, the first rising speed of the horizontal plane is accurately predicted by calling a predetermined trend prediction algorithm and using the first real-time distance in combination with the trend prediction algorithm.

It should be noted that, in this embodiment, the trend prediction algorithm is an algorithm for predicting the future of the current phenomenon by calculating an exponential smoothing value and matching with a certain time series prediction model, and the calculation principle of the algorithm is that the exponential smoothing value in any stage is a weighted average of the actual observed value in the present stage and the exponential smoothing value in the previous stage.

Specifically, for example, considering that the water level where actual flood occurs has waves, and the rising height of the water level is not in proportion to the time, the water level early warning method specifically uses cubic exponential smoothing in a trend prediction algorithm to perform trend prediction, wherein a calculation formula of the cubic exponential smoothing is as follows:

thus, the first real-time distance is used in combination with the trend prediction algorithm to predict the water level height value Y of the water level at the future T period according to the first rising speed_t+TComprises the following steps:

Y_t+T＝A_t+B_tT+C_tT²。

among them, in the above-mentioned case,

it should be noted that, in this embodiment, since the first real-time distance is used in combination with the trend prediction algorithm to predict the water level according to the first rising speed, the water level height value in the future T period is Y_t+TThe first rising speed obtained by reverse calculation is: y is_t+T/T。

And step S30, issuing early warning information according to the first rising speed and a preset water level early warning value.

And the terminal equipment uses the first real-time distance by combining a trend prediction algorithm, accurately predicts and obtains the first rising speed of the horizontal plane, and then judges and issues corresponding early warning information based on the first rising speed and a preset water level early warning value.

It should be noted that, in this embodiment, the water level early warning value is a preset maximum water level early warning value that ensures that each electrical device of the photovoltaic power station is not submerged by water or damaged due to wetting. It should be understood that, based on different design requirements of practical applications, in different practical application scenarios, the maximum water level warning value for ensuring that each electrical device is not submerged or soaked by water to be damaged may be different, and therefore, the water level warning method of the present invention is not limited to a specific size of the water level warning value.

Further, in a possible embodiment, in step S30, the step of issuing warning information according to the first rising speed and a preset water level warning value may include:

step S301, calculating a water level risk value according to the first rising speed and preset effective action time;

it should be noted that, in this embodiment, the preset effective action time is an effective time for operation and maintenance staff of the photovoltaic power station to be able to discharge flood water so as to ensure that the electrical equipment is not submerged or wetted and damaged.

After the terminal equipment accurately predicts the first rising speed of the water level by combining a trend prediction algorithm and using the first real-time distance, the terminal equipment calculates and obtains a water level risk value to which the water level may rise after the effective action time by using the first rising speed and the preset effective action time.

Step S302, detecting the water level risk value and the water level early warning value to obtain a detection result, and determining to issue the early warning information according to the detection result.

After calculating a water level risk value which is possibly increased to by the water level after the preset effective action time, the terminal equipment compares the water level risk value with a preset water level early warning value, so that the size between the water level risk value and the water level early warning value is detected to obtain a detection result, and when the detection result shows that the water level risk value is larger than or equal to the water level early warning value, the terminal equipment judges that corresponding early warning information is immediately issued.

Specifically, for example, please refer to the application flow shown in fig. 3, assuming that the current photovoltaic plant performing flood warning is a photovoltaic plant constructed by piling up on a horizontal plane, during the process of performing flood warning on the photovoltaic plant, the terminal device sets a water level warning value H for ensuring that each electrical device, such as a photovoltaic panel, of the photovoltaic plant is not submerged or wetted and damaged, and sets an effective action time T for the operation and maintenance staff of the photovoltaic plant to be able to remove flood to ensure that the photovoltaic panel is not submerged or wetted and damaged. Then, a first real-time distance h' between the horizontal plane and the lowest edge of the photovoltaic panel, which is acquired by the distance sensor in real time, is acquired, and trend prediction is performed by using cubic exponential smoothing in a trend prediction algorithm by combining the first real-time distance and the pre-selected trend prediction algorithm, so as to predict a water level risk value h (a water level value h after the time T shown in fig. 3) to which the horizontal plane may possibly rise after the effective action time T elapses. The terminal equipment compares the water level risk value H with the water level early warning value H to detect the size between the water level risk value H and the water level early warning value H and obtain a detection result, so that the terminal equipment detects that the detection result is that: and H is greater than or equal to H, namely when the water level risk value H is greater than or equal to the water level early warning value H, the flood early warning is judged to be issued immediately.

Further, in another possible embodiment, the detection result of the terminal device detecting the magnitude between the water level risk value H and the water level warning value H is as follows: and H is smaller than H, namely when the water level risk value H is smaller than the water level early warning value H, the flood early warning is judged not to need to be issued.

The embodiment of the invention provides a water level early warning method, which is characterized in that in the process of carrying out flood early warning on a photovoltaic power station through terminal equipment, a first real-time distance between any electrical equipment forming the photovoltaic power station is constructed by acquiring a horizontal plane distance; after the terminal equipment obtains a first real-time distance between a horizontal plane and the electrical equipment, a first rising speed of the horizontal plane is accurately predicted by calling a predetermined trend prediction algorithm and using the first real-time distance in combination with the trend prediction algorithm; and the terminal equipment uses the first real-time distance by combining a trend prediction algorithm, accurately predicts and obtains the first rising speed of the horizontal plane, and then judges and issues corresponding early warning information based on the first rising speed and a preset water level early warning value.

Compared with the traditional mode of predicting the water level based on manual inspection or by combining site data with existing historical data, the method disclosed by the invention can be used for predicting the rising of the water level by acquiring the real-time distance between the horizontal plane and the electrical equipment and combining a trend prediction algorithm, so that the early warning information can be issued in time under the condition that the rising trend of the water level possibly exceeds the highest early warning value of the water level, further the electrical equipment of the photovoltaic power station is effectively prevented from being damaged by water, and the safety of the photovoltaic power station is improved.

Further, in a possible embodiment, the step S20 of predicting the first ascending speed of the horizontal plane by using the first real-time distance through a preset trend prediction algorithm may include:

step S201, calling the trend prediction algorithm, and extracting the minimum distance in the first real-time distances;

after the terminal equipment obtains the first real-time distance between the horizontal plane and the photovoltaic panel, a predetermined trend prediction algorithm is called, and the minimum value is extracted from the first real-time distances corresponding to all the moments and used for predicting the first rising speed of the horizontal plane by combining the minimum distance with the trend prediction algorithm.

Specifically, in this embodiment, the terminal device may determine and extract the minimum distance from the first real-time distances corresponding to the respective times in a traversal manner.

Step S202, the trend prediction algorithm is operated by using the minimum distance so as to predict and obtain a first rising speed of the horizontal plane.

After the terminal device extracts the minimum distance in the first real-time distances corresponding to the moments, the terminal device predicts the first rising speed of the horizontal plane by using the minimum distance in combination with the called trend prediction algorithm.

It should be noted that, in this embodiment, the process of the terminal device using the minimum distance to predict the first ascending speed of the horizontal plane in combination with the trend prediction algorithm is the same as the process of predicting using the first implemented distance in step S20, and therefore, the description of the process of using the minimum distance to predict the first ascending speed in combination with the trend prediction algorithm is omitted here.

Further, in a possible embodiment, after the step S202, the water level warning method of the present invention may further include:

step S203, adjusting the first rising speed according to a preset trend correction value to obtain an adjusted first rising speed.

It should be noted that, in the present embodiment, in the process of prediction by combining with the trend prediction algorithm, after the smoothing coefficient is determined, the obtained ascending or descending trend presented by the real-time distance collected by the distance sensor in real time in a period of time will cause the exponential prediction to lag the actual value. Therefore, after the first rising speed is obtained through preliminary prediction, the water level early warning method further adjusts the first rising speed of the trend prediction, namely, the index smooth prediction result is improved by adding the trend correction value, so that the prediction is more accurate.

Specifically, for example, the algorithm formula of the trend prediction algorithm optimized by adding the trend correction value is: adjustment trend prediction (Y)_t+TT_t+T) Smooth prediction (Y)_t+T) + Trend correction (T)_t+T). The terminal device performs trend prediction by using the first real-time distance or the minimum distance in the first real-time distance through a trend prediction algorithm to obtain a value as follows: y is_t+TAnd then the terminal device further uses the formula: t is_t+T＝(1-α)T_t+T-1+α(Y_t+T-Y_t+T-1) To calculate a trend correction, wherein T_t+TThe trend of the Tth period over smoothing, T_t+T-1The trend of the earlier period of the T-th period is smoothed, alpha is a selected trend smoothing coefficient, and Y is_t+TAs to the firstCubic exponential smoothing prediction of T phase, and, Y_t+T-1And (4) carrying out three exponential smoothing prediction on the T-th stage and the last stage. The terminal equipment smoothes the predicted value (Y) by calculating the index after the trend adjustment_t+TT_t+T)＝Y_t+T+T_t+T。

Further, based on the above first embodiment of the water level early warning method of the present invention, a second embodiment of the water level early warning method of the present invention is provided. The main difference between this embodiment and the first embodiment is that, in this embodiment, after issuing the warning information according to the first rising speed and the preset water level warning value in step S30 of the first embodiment, the water level warning method of the present invention may further include:

and step S40, executing early warning operation to avoid the damage of the electrical equipment of the photovoltaic power station.

When the terminal equipment judges and issues the early warning information, corresponding early warning operation is synchronously executed to avoid damage caused by the fact that electrical equipment of the photovoltaic power station is submerged by the rising horizontal plane.

Further, in a possible embodiment, the pre-warning operation includes: and/or starting a preset water pumping system, wherein the step S40 may include:

step S401, when the early warning information is detected to be issued, the inclination angle is adjusted to enable the electrical equipment and the horizontal plane to reach a preset state, and/or a preset water pumping system is controlled to be started, so that the electrical equipment of the photovoltaic power station is prevented from being damaged.

The detection result of the terminal equipment between the detected water level risk value and the detected water level early warning value represents that: the water level risk value is larger than or equal to the water level early warning value, so that when corresponding early warning information is immediately issued, corresponding early warning operation is further executed to adjust the inclination angle of the electrical equipment of the photovoltaic power station to enable the electrical equipment and the horizontal plane to achieve a preset state, and/or a preset water pumping system is synchronously controlled to be started to pump water to achieve flood discharge operation, and therefore the situation that the electrical equipment of the photovoltaic power station is submerged or soaked to cause damage of the photovoltaic power station due to water flooding is avoided.

It should be noted that, in the present embodiment, the predetermined state that the electrical device and the horizontal plane achieve by adjusting the inclination angle includes, but is not limited to: the plane on which the electrical equipment is positioned is parallel to the horizontal plane.

Specifically, for example, referring to the application flow shown in fig. 3, the detection result of the terminal device detecting the magnitude between the water level risk value H and the water level warning value H is as follows: h is greater than or equal to H, namely, the water level risk value H is greater than or equal to the water level early warning value H, so that under the condition that the flood early warning is judged to be issued immediately, once the terminal equipment detects that the flood early warning is judged to be issued, the angle between the electrical equipment in the photovoltaic power station relative to the opposite plane is further controlled and adjusted until the electrical equipment and the horizontal plane are parallel to each other, or a preset water pumping system is started to discharge the flood under synchronous control, and therefore the electrical equipment of the photovoltaic power station is prevented from being damaged due to the fact that the photovoltaic panel is submerged or wetted by water.

It should be noted that, in this embodiment, the water pumping system is preset to establish a communication connection with the terminal device in advance. The preset water pumping system is used for a functional system for performing flood discharge operation to reduce the water level. It should be understood that, based on the actual application without design requirements, in different possible embodiments, the terminal device may be connected to a water pumping system for performing a flood discharge function, which may be of different types, and the water level warning method of the present invention is not specifically limited to the specific type and implementation principle of the water pumping system.

Further, in a possible embodiment, in the step S401, the step of adjusting the inclination angle to enable the electrical equipment to reach a predetermined state with the horizontal plane and controlling to activate a preset water pumping system may include:

step S4011, adjusting the inclination angle to enable the electrical equipment and the horizontal plane to reach a preset state;

the detection result of the terminal equipment between the detected water level risk value and the detected water level early warning value represents that: the water level risk value is greater than or equal to the water level early warning value, so that when corresponding early warning information is judged to be issued immediately, corresponding early warning operation is executed to adjust the inclination angle of the electrical equipment of the photovoltaic power station relative to the ground plane, and the electrical equipment and the ground plane reach a preset state.

Step S4012, determining a second rising speed of the horizontal plane when the electrical equipment is in the predetermined state;

when the terminal equipment judges that the corresponding early warning information is issued, the terminal equipment further executes corresponding early warning operation to firstly adjust the inclination angle of the electric equipment relative to the ground plane, so that after the electric equipment and the horizontal plane reach a preset state, the terminal equipment determines the second rising speed of the horizontal plane again when the electric equipment and the horizontal plane reach the preset state.

Further, in a possible embodiment, the step S3041 may include:

step A, acquiring a second real-time distance between the horizontal plane and the electrical equipment when the electrical equipment is in the preset state;

and the terminal equipment adjusts the inclination angle of the electrical equipment relative to the ground plane in response to the early warning operation to enable the electrical equipment and the horizontal plane to reach a preset state, and then obtains a second real-time distance between the horizontal plane and the lowest edge of the electrical equipment through real-time acquisition of each distance sensor installed on the electrical equipment.

It should be noted that, in this embodiment and other embodiments set forth herein, the number of distance sensors mounted on the electrical equipment is at least greater than or equal to 3.

And B, predicting a second rising speed of the horizontal plane by using the second real-time distance through the trend prediction algorithm.

After further obtaining a second real-time distance between the electrical equipment and the lowest edge of the electrical equipment, the terminal equipment still calls a predetermined trend prediction algorithm to use the second real-time distance in combination with the trend prediction algorithm to accurately predict the second rising speed of the horizontal plane at the moment.

It should be noted that, in this embodiment, the process of the terminal device using the second real-time distance to predict the second ascending speed of the horizontal plane in combination with the trend prediction algorithm is the same as the process of using the first implemented distance to predict the second ascending speed in step S20, and therefore, details about the process of using the second real-time distance to predict the second ascending speed in combination with the trend prediction algorithm are not repeated herein.

And S3042, controlling and starting the water pumping system according to the second rising speed and the water level early warning value.

And the terminal equipment uses the second real-time distance by combining with a trend prediction algorithm, accurately predicts and releases corresponding early warning information based on the second rising speed and a preset water level early warning value after the second rising speed of the horizontal plane is obtained, and controls and starts a preset water pumping system to operate to discharge the flood when the early warning information is judged and released, so that the water pumping system is further controlled to discharge the flood on the basis of adjusting the inclination angle of the electrical equipment to avoid the electrical equipment from being submerged or soaked to cause the photovoltaic power station to be damaged.

The water level early warning method provided by the invention is characterized in that in the process of carrying out flood early warning on a photovoltaic power station, a distance sensor is used for measuring and recording the distance between a horizontal plane and the lowest edge of electrical equipment of the photovoltaic power station, a curve graph of the rising height of the horizontal plane and the time is obtained through a trend prediction method, when the water level rises to an early warning range, corresponding early warning operation is carried out to adjust the inclination angle of the electrical equipment of the photovoltaic power station so that the electrical equipment and the horizontal plane reach a preset state, and/or a preset water pumping system is synchronously controlled and started to pump water so as to realize flood discharge operation. The minimum distance between the horizontal plane and the electrical equipment can be effectively determined through more than 3 distance sensors, the rising speed and the residual response time of the water level can be effectively predicted by using a trend prediction method, the cubic exponential smoothing trend prediction is corrected, the prediction accuracy is greatly improved, and the early warning accuracy is improved. When the water level and the rising trend reach the preset values, the inclination angle of the electrical equipment is adjusted and the water pumping system is started, so that the operation safety of the photovoltaic power station can be effectively guaranteed.
