[0028] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0029] It should be noted that although the device schematics illustrate functional module divisions and the flowcharts illustrate logical sequences, in certain circumstances, the steps shown or described may be performed in a sequence that differs from the module divisions in the device or the sequence in the flowcharts. The terms "first," "second," and so on, in the specification, claims, and drawings, are used to distinguish similar items and are not necessarily used to describe a specific sequence or precedence.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0031] like Figures 1 to 4As shown, a drainage control method according to an embodiment of the first aspect of the present invention is applied to a drainage system, wherein the drainage system includes multiple water collection nodes 100, each water collection node 100 includes a water storage area, each water storage area has a water inlet 110 and several drains 120, each water storage area is provided with a water level detection module 210, a control module 220 and several switch valve groups 300, the water level detection module 210 is used to detect the current water level value of the water storage area, the switch valve group 300 is arranged one-to-one at the drain 120, and the drain 120 of one water collection node 100 is connected to the water inlet 110 of another water collection node 100 through the switch valve group 300 and the pipeline, and the control module 220 is connected to the water level detection module 210 and the switch valve group 300 respectively.

[0032] It should be noted that the drainage system can be applied to the substation system, power plant system or underground pipeline drainage system in the power grid. Taking the power grid system as an example, each water collection node 100 can include each substation, each power plant, each water storage tank, etc. Each water collection node 100 can be regarded as a water storage area. Each water storage area has multiple water inlets 110. The drain outlet 120 of the upstream water collection node 100 can be connected to the water inlet 110 of the downstream water collection node 100. Each water collection node 100 can be connected to multiple downstream water collection nodes 100. Rainwater can also flow directly into the water storage area. Whether the water collection node 100 is drained is determined by whether the switch valve group 300 of the drain outlet 120 is turned on.

[0033] In a substation, the water storage area may include a water collection well and a park. The water collection well is opened in the ground of the park and is located below the park. The park is used to house substation equipment. A submersible water level meter can be installed in the water collection well, and an electronic water gauge can be installed on the wall of the park. The actual water level value of the water storage area is determined by the detection results of the submersible water level meter and the electronic water gauge. The control module 220 may include a CPU or MCU and its associated circuits. The switch valve group 300 may include at least one water valve or multiple water valves arranged in parallel. Under normal conditions, each water valve remains closed. The main water valve controls the opening and closing of the drain outlet 120. In the event of a main water valve failure, the other water valves act as bypasses to control the opening and closing of the drain outlet 120. The water valve can be a submersible electric ball valve with a waterproof rating of IP68, which supports remote opening and closing and manual emergency operation. The valve has a built-in magnetic positioning structure to ensure precise closure under the impact of high-pressure water flow and also has anti-lock protection function.

[0034] It can be understood that the water storage area can set water storage level thresholds, safety water level thresholds and dangerous water level thresholds from small to large according to the needs of its own water collection node 100. Among them, the water storage level threshold can be used to indicate that the water level in the current water storage area has reached the standard required for discharge, and it can also receive drainage from upstream. The safety water level threshold can be used to indicate that the water level in the current water storage area is not recommended to receive too much upstream drainage, but if it is urgently needed, it can also receive part of the upstream drainage. The dangerous water level threshold can be used to indicate that the water level in the current water storage area has reached a water level that is dangerous to the equipment in the park, and it is necessary to drain the water in time and prevent external water from entering, otherwise it will cause damage.

[0035] In addition, the control module 220 of each water collection node 100 can be provided with a network port or a wireless transmission module. The control module 220 transmits data with other control modules 220 through the cloud server to achieve interconnection. Specifically, water level data, equipment status and alarm information can be uploaded to the monitoring platform in real time through the 4G / NB-IoT network, supporting access from multiple terminals (PC, mobile phone APP).

[0036] A solar panel 230 and a battery 240 may be provided at the water collection node 100 . The solar panel 230 converts solar energy into electrical energy and stores it in the battery 240 . The battery 240 then powers the control module 220 , the water level detection module 210 , and the switch valve assembly 300 .

[0037] Among them, Figure 3 、 4 As shown, the drainage control method includes:

[0038] S410, obtaining monitoring mode setting information, wherein the monitoring mode setting information includes a normal period setting instruction and a flood season setting instruction;

[0039] S420: Execute a normal monitoring mode or a flood season monitoring mode according to the monitoring mode setting information; S430: In the normal monitoring mode, cyclically trigger and execute a water detection and discharge step at a first monitoring frequency; S440: In the flood season monitoring mode, cyclically trigger and execute a water detection and discharge step at a second monitoring frequency, wherein the first monitoring frequency is less than the second monitoring frequency;

[0040] The water detection and discharge step comprises:

[0041] S510, obtaining the current water level value;

[0042] S520: When the current water level exceeds the water level threshold, control at least one switch valve group 300 to open to drain water.

[0043] It should be noted that the monitoring mode setting information is usually released by the personnel of the monitoring center. The staff will release corresponding monitoring mode setting information for the water collection nodes 100 in each region based on the recent flood prevention situation in each region, including regular setting instructions and flood season setting instructions. The control module 220 of each water collection node 100 switches between regular monitoring mode and flood season monitoring mode according to the monitoring mode setting information.

[0044] This drainage control method switches modes according to whether it is in the flood season. If it is in the flood season, the risk of flooding increases, and the flood season monitoring mode can be executed according to the flood season setting instruction. In the flood season monitoring mode, the water detection and discharge steps are triggered cyclically with a more intensive second monitoring frequency to increase the frequency of obtaining the actual water level value, and when the current water level value exceeds the water storage level threshold, at least one switch valve group 300 is controlled to open and drain water in time. During normal times, the probability of water level rise is reduced. At this time, in order to save electricity, the system can be switched to the regular monitoring mode through the regular setting instruction. In the regular monitoring mode, the water detection and discharge steps are triggered cyclically with a lower second monitoring frequency, which saves electricity while also ensuring water level monitoring. This design changes different detection strategies based on different periods to ensure reasonable and orderly drainage, take timely countermeasures to rising water levels, and save operating costs.

[0045] In some embodiments of the present invention, the drainage control method further includes:

[0046] Obtain weather forecast information, which is used to characterize the severity of the weather;

[0047] Analyze the frequency correction parameter based on the weather forecast information, wherein the more severe the weather is, the larger the frequency correction parameter is;

[0048] The frequency correction parameter is multiplied by the first monitoring frequency to obtain the first corrected monitoring frequency. In the normal monitoring mode, the first corrected monitoring frequency is used to cyclically trigger the execution of the water detection and discharge step. Moreover, the frequency correction parameter is multiplied by the second monitoring frequency to obtain the second corrected monitoring frequency. In the flood season monitoring mode, the second corrected monitoring frequency is used to cyclically trigger the execution of the water detection and discharge step.

[0049] During the drainage process, the weather will have a greater impact on the rise of the water level. Therefore, the staff can set the severity level according to the weather forecast information to represent the severity of the weather. In the database or the preset processing model of the weather severity and the frequency correction parameter, the corresponding frequency correction parameter is paired according to the severity of the weather. The control module 220 analyzes the frequency correction parameter according to the weather forecast information. For example, when the weather is clear, the frequency correction parameter is 1, when the weather is light rain, the frequency correction parameter is 1.2, when the weather is moderate rain, the frequency correction parameter is 1.5, and when the weather is heavy rain, the frequency correction parameter is 2.

[0050] The frequency correction parameter is then multiplied by the first monitoring frequency to correct the detection trigger frequency in the normal monitoring mode. The frequency correction parameter is also multiplied by the second monitoring frequency to correct the monitoring trigger frequency in the flood season monitoring mode. For example, if the first monitoring frequency is triggered once every five minutes, when it rains heavily, the frequency correction parameter is 2, then the corrected first corrected monitoring frequency is triggered twice every five minutes. Similarly, if the first monitoring frequency is triggered once per minute, when it rains heavily, the frequency correction parameter is 2, then the corrected second corrected monitoring frequency is triggered twice per minute.

[0051] In some embodiments of the present invention, the water storage area has multiple drain outlets 120, and each drain outlet 120 is connected to another water collection node 100. Before controlling the switch valve group 300 to open for drainage, the following steps are further included:

[0052] Monitor each connected water collection node 100 to see if it outputs warning information, where the warning information indicates that the current water level of the water collection node 100 exceeds the safety water level threshold;

[0053] The water collection node 100 that has not outputted the warning information is selected, and all the switch valve groups 300 for connecting to the selected water collection node 100 are controlled to open to drain water.

[0054] It can be understood that the water collection node 100 located upstream can be connected to multiple water collection nodes 100 located downstream, and the control modules 220 are interconnected. The control module 220 of the upstream water collection node 100 monitors whether the control module 220 of the downstream water collection node 100 outputs early warning information. When the downstream water collection node 100 outputs early warning information, it proves that the current water level value of the downstream water collection node 100 exceeds the safe water level threshold. The upstream water collection node 100 can give priority to other upstream water collection nodes 100 for discharge, thereby alleviating the water accumulation pressure of each water collection node 100.

[0055] In some embodiments of the present invention, in the monitoring of whether each docked water collection node 100 outputs warning information, if all docked water collection nodes 100 output warning information, then an alarm message is output.

[0056] It is understandable that when all the connected water collection nodes 100 output warning information, it proves that each downstream water collection node 100 is in a tense state of water accumulation. At this time, it is necessary to output warning information to inform the staff of the specific situation, and the staff will control which switch valve groups 300 to open. Specifically, the warning information can be a beep, voice broadcast sound, warning light, screen pop-up, SMS push, etc.

[0057] In some embodiments of the present invention, the monitoring center obtains data output by the control module 220 of each water collection node 100, and can establish a data presentation chart based on the drainage network topology in the area. The icon information can reflect the water accumulation situation of each water collection node 100, the on-off status of the switch valve group 300 of each water collection node 100, and the drainage flow direction, etc.

[0058] In some embodiments of the present invention, controlling the switch valve groups 300 of all selected water collection nodes 100 to open to drain water includes:

[0059] Continuously monitor the warning information of the drained water collection node 100;

[0060] When any of the drained water collection nodes 100 outputs warning information, the switch valve group 300 connected to the water collection node 100 that outputs the warning information is closed.

[0061] It can be understood that during the drainage process of the upstream water collection node 100, when the current water level value of the originally selected downstream water collection node 100 exceeds the safe water level threshold, the control module 220 can control the shutdown of the switch valve group 300 corresponding to the water collection node 100 to prevent continuous drainage from causing the water accumulation in the water collection node 100 to be higher than the dangerous water level threshold.

[0062] In some embodiments of the present invention, the step of selecting a water collection node 100 that does not output warning information and controlling all the switch valve groups 300 connected to the selected water collection node 100 to open to drain water includes:

[0063] Obtaining a water level difference of each selected water collection node 100 , wherein the water level difference is the difference between a safe water level threshold and a current water level value of the water collection node 100 ;

[0064] Calculate the opening threshold of the switch valve group 300 connected to the water collection node 100 according to the water storage difference;

[0065] The switch valve group 300 of the water collection node 100 is controlled to open according to the opening threshold to drain water.

[0066] It can be understood that the water storage difference can reflect the water accumulation pressure of the water collection node 100. The smaller the water storage difference, the greater the water accumulation pressure. Conversely, the larger the water storage difference, the more water can be accommodated. The water storage difference of each selected water collection node 100 is obtained. For the water collection node 100 with a larger water storage difference, the opening threshold of the switch valve group 300 connected to its water inlet 110 can be larger, and for the water collection node 100 with a smaller water storage difference, the opening threshold of the switch valve group 300 connected to its water inlet 110 can be smaller, so as to reasonably divert the water of the upstream water collection node 100 to each downstream water collection node 100.

[0067] Specifically, the calculation of the opening threshold of the switch valve group 300 connected to the water collection node 100 according to the water storage difference includes:

[0068] The conversion ratio is calculated using the water storage difference and the per-unit water storage difference value;

[0069] The opening threshold of the switch valve group 300 of the water collection node 100 is calculated using the conversion ratio and the total opening extreme value, wherein the total opening extreme value is the threshold when the switch valve group 300 is fully turned on.

[0070] It should be noted that the water storage difference per unit value is a reference value, which can be set by the staff and can be set according to the water storage value. Specifically, the water storage level threshold, the safety water level threshold and the dangerous water level threshold can all be calculated as the water storage difference per unit value. The water storage difference is divided by the water storage difference per unit value to obtain the conversion ratio, and then the product of the conversion ratio and the total opening extreme value is used to obtain the opening threshold value of the switch valve group 300, or the conversion ratio and the total opening extreme value can be used to obtain the opening threshold value of the switch valve group 300 according to a linear relationship function.

[0071] According to the second aspect of the present invention, the power station drainage system includes multiple water collection nodes 100, each water collection node 100 includes a water storage area, each water storage area has a water inlet 110 and several drains 120, each water storage area is provided with a water level detection module 210, a control module 220 and several switch valve groups 300, the water level detection module 210 is used to detect the current water level value of the water storage area, the switch valve group 300 is arranged one-to-one at the drain 120, and the drain 120 of one water collection node 100 is connected to the water inlet 110 of another water collection node 100 through the switch valve group 300 and the pipeline, and the control module 220 is respectively connected to the water level detection module 210 and the switch valve group 300 to execute the drainage control method disclosed in any of the above embodiments.
