The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0031] As Figures 1 to 4As shown, according to the first aspect of the embodiment of the application, a drainage control method is applied to a drainage system, the drainage system includes a plurality of water collection nodes 100, each water collection node 100 includes a water storage area, each water storage area has a water inlet 110 and a plurality of drainage outlets 120, each water storage area is provided with a water level detection module 210, a control module 220 and a plurality of 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 correspondingly arranged at the drainage outlet 120, the drainage outlet 120 of one water collection node 100 is connected with 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 with 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 a power grid system, a power plant system or an underground pipe gallery drainage system, etc. 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 a plurality of water inlets 110, the drainage outlet 120 of the upstream water collection node 100 can be connected with the water inlet 110 of the downstream water collection node 100, each water collection node 100 can be connected with a plurality of downstream water collection nodes 100, and the rainwater can also directly flow into the water storage area, and whether the water collection node 100 is drained is determined by whether the switch valve group 300 of the drainage outlet 120 is turned on.

[0033] In the substation, the water storage area can include a water collection well and a park area, the water collection well is opened in the ground of the park area and located below the park area, and the park area is used to accommodate the power transformation equipment. The water level instrument can be arranged in the water collection well, and the electronic water gauge can be arranged on the wall of the park area. The actual water level value of the water storage area is obtained from the detection results of the water level instrument and the electronic water gauge. The control module 220 can include CPU or MCU and its auxiliary circuit. The switch valve group 300 can include at least one water valve, or a plurality of water valves in parallel. In the normal state, each water valve is kept off. The main water valve controls the on-off of the drainage outlet 120. When the main water valve fails, the other water valves control the on-off of the drainage outlet 120 as a bypass. The water valve can be a submersible electric ball valve with a waterproof level of IP68, which supports remote opening and closing and manual emergency operation. The valve has a built-in magnetic positioning structure to ensure accurate closure under high-pressure water flow, and has an anti-lock protection function.

[0034] It can be understood that the water storage area can set a small to large water storage water level threshold, a safe water level threshold and a dangerous water level threshold according to the needs of the water collection node 100 itself, wherein the water storage water level threshold can be used to indicate that the water level of the water storage area reaches the standard of needing to be discharged, and can also receive the upstream drainage, the safe water level threshold can be used to indicate that the water level of the water storage area does not recommend receiving too much upstream drainage, but if it is urgently needed, it can also receive part of the upstream drainage, and the dangerous water level threshold can be used to indicate that the water level of the water storage area has reached a dangerous water level for the equipment in the park, and needs to be drained in time and to prevent external water from entering, otherwise damage will be caused.

[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, and the control module 220 can transmit data with other control modules 220 through a cloud server to realize interconnection. Specifically, the water level data, equipment status and alarm information can be uploaded to the monitoring platform in real time through a 4G / NB-IoT network, and multiple terminals (PC, mobile phone APP) are supported to access.

[0036] A solar panel 230 and a storage battery 240 can be provided at the water collection node 100, the solar panel 230 converts solar energy into electrical energy and stores it in the storage battery 240, and the storage battery 240 supplies power to the control module 220, the water level detection module 210 and the switch valve group 300.

[0037] As shown in FIGS. 1, 2 and 3, the water collection node 100 includes a water level detection module 210, a control module 220 and a switch valve group 300. Figure 3 、 4 The drainage control method includes:

[0038] S410, acquiring monitoring mode setting information, wherein the monitoring mode setting information includes a regular setting instruction and a flood season setting instruction;

[0039] S420, executing a regular monitoring mode or a flood season monitoring mode according to the monitoring mode setting information, S430, in the regular monitoring mode, executing the water detection and drainage step in a cycle triggered by a first monitoring frequency, S440, in the flood season monitoring mode, executing the water detection and drainage step in a cycle triggered by a second monitoring frequency, wherein the first monitoring frequency is less than the second monitoring frequency;

[0040] The water detection and drainage step includes:

[0041] S510, acquiring a current water level value;

[0042] S520, when the current water level value exceeds the water storage water level threshold, controlling 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 issued by the personnel of the monitoring center, and the personnel issues the corresponding monitoring mode setting information for each regional water collection node 100 according to the recent flood prevention situation of each region, which includes the regular setting instruction and the flood season setting instruction, and the control module 220 of each water collection node 100 switches between the regular monitoring mode and the flood season monitoring mode according to the monitoring mode setting information.

[0044] The present drainage control method switches modes according to whether it is in the flood season, and if it is in the flood season, the flood risk increases, so the flood season monitoring mode can be executed according to the flood season setting instruction, in which the water level detection and drainage step is cyclically triggered and executed at a more intensive second monitoring frequency, the frequency of obtaining the actual water level value is increased, and at least one switch valve group 300 is controlled to open in time to drain water when the current water level value exceeds the water storage water level threshold. At regular times, the probability of water level rising is reduced, and at this time, in order to save power, the system can be switched to the regular monitoring mode by the regular setting instruction, in which the water level detection and drainage step is cyclically triggered and executed at a lower second monitoring frequency, saving power while ensuring monitoring of the water level. The present design changes different detection strategies based on different periods to ensure reasonable and orderly drainage and timely response to rising water levels, thereby saving operating costs.

[0045] In some embodiments of the present application, the drainage control method further comprises:

[0046] Obtaining weather forecast information, the weather forecast information being used to represent the severity of the weather;

[0047] According to the weather forecast information, a frequency correction parameter is analyzed, wherein the higher the severity of the weather, the larger the frequency correction parameter;

[0048] The first correction monitoring frequency is obtained by multiplying the frequency correction parameter and the first monitoring frequency, the water level detection and drainage step is cyclically triggered and executed at the first correction monitoring frequency in the regular monitoring mode, and the second correction monitoring frequency is obtained by multiplying the frequency correction parameter and the second monitoring frequency, the water level detection and drainage step is cyclically triggered and executed at the second correction monitoring frequency in the flood season monitoring mode.

[0049] In the drainage process, the weather has a greater impact on the rising 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 severity of the weather and the frequency correction parameter, there is a corresponding frequency correction parameter 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 sunny, 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 multiplied by the first monitoring frequency to correct the detection trigger frequency in the normal period monitoring mode, and the frequency correction parameter is also multiplied by the second monitoring frequency to correct the monitoring trigger frequency in the flood period 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, and the corrected first correction monitoring frequency is triggered twice every five minutes. Similarly, if the first monitoring frequency is triggered once every minute, when it rains heavily, the frequency correction parameter is 2, and the corrected second correction monitoring frequency is triggered twice every minute.

[0051] In some embodiments of the present application, the water storage area has multiple drainage outlets 120, each drainage outlet 120 is connected to other water collection nodes 100, and before the control switch valve group 300 is opened for drainage, it further includes:

[0052] Listening to whether each connected water collection node 100 outputs early warning information, wherein the early warning information is used to represent that the current water level value of the water collection node 100 exceeds the safe water level threshold;

[0053] For the selected water collection node 100 that does not output early warning information, control all switch valve groups 300 connected to the selected water collection node 100 to open for drainage.

[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 interconnection of each control module 220, the control module 220 of the water collection node 100 located upstream listens to whether the control module 220 of the water collection node 100 located downstream outputs early warning information. When the water collection node 100 located downstream outputs early warning information, it proves that the current water level value of the water collection node 100 located downstream exceeds the safe water level threshold. The water collection node 100 located upstream can preferentially select other water collection nodes 100 located upstream for drainage, thereby reducing the waterlogging pressure of each water collection node 100.

[0055] In some embodiments of the present application, in the listening to whether each connected water collection node 100 outputs early warning information, if all connected water collection nodes 100 output early warning information, an alarm information is output.

[0056] It can be understood that when all connected water collection nodes 100 output early warning information, it proves that each water collection node 100 located downstream is in a waterlogging stress state. At this time, early warning information needs to be output to inform the staff of the specific situation, and the staff controls which switch valve groups 300 to open. Specifically, the early warning information can be a buzzing sound, a voice broadcast sound, a warning light, a screen pop-up window, a short message push, etc.

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

[0058] In some embodiments of the present application, in the process of controlling all the selected switch valve groups 300 of the catchment nodes 100 to open for drainage, the following steps are included:

[0059] Continuously monitoring the early warning information of the catchment nodes 100 being drained;

[0060] When any one of the catchment nodes 100 being drained outputs early warning information, the switch valve group 300 of the catchment node 100 outputting the early warning information is controlled to close.

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

[0062] In some embodiments of the present application, in the process of selecting the catchment nodes 100 not outputting early warning information, the following steps are included:

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

[0064] Calculating the opening valve value of the switch valve group 300 corresponding to the catchment node 100 according to the water storage difference value;

[0065] Controlling the switch valve group 300 of the catchment node 100 to open for drainage according to the opening valve value.

[0066] It can be understood that, according to the water storage difference value, the water accumulation pressure of the catchment node 100 can be reflected. The smaller the water storage difference value is, the greater the water accumulation pressure is. Conversely, the greater the water storage difference value is, the more water can be accommodated. Obtaining the water storage difference value of each selected catchment node 100, the opening valve value of the switch valve group 300 corresponding to the water inlet 110 of the catchment node 100 with a larger water storage difference value can be larger, while the opening valve value of the switch valve group 300 corresponding to the water inlet 110 of the catchment node 100 with a smaller water storage difference value can be smaller. The water of the upstream catchment node 100 is reasonably diverted to each downstream catchment node 100.

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

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

[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, where the total opening extreme value is the threshold value when the switch valve group 300 is fully open.

[0070] It should be noted that the per-unit value of the water level difference is a reference value and can be set by the staff. It can be set according to the water level value. Specifically, the water level threshold, safe water level threshold, and dangerous water level threshold can all be used as the per-unit value of the water level difference for calculation. The water level difference is divided by the per-unit value of the water level difference to obtain the conversion ratio. Then, the opening threshold of the switch valve group 300 is obtained by multiplying the conversion ratio and the total opening extreme value. Alternatively, the opening threshold of the switch valve group 300 can be obtained by using the conversion ratio and the total opening extreme value according to a linear relationship function.

[0071] According to a second aspect of the present invention, a power plant drainage system includes multiple water collection nodes 100, each water collection node 100 including a water storage area, each water storage area having an inlet 110 and a plurality of outlets 120, each water storage area being provided with a water level detection module 210, a control module 220 and a plurality of switch valve groups 300, the water level detection module 210 being used to detect the current water level value of the water storage area, the switch valve groups 300 being correspondingly provided at the outlets 120, the outlets 120 of one water collection node 100 being connected to the inlet 110 of another water collection node 100 through the switch valve groups 300 and pipes, the control module 220 being connected to the water level detection module 210 and the switch valve groups 300 respectively to execute the drainage control method disclosed in any of the above embodiments.
