TECHNICAL FIELD

[0001] The embodiment of the present application relates to the rainfall prediction technical field, and particularly relates to a rainfall intensity statistical analysis method and device, equipment and a storage medium. BACKGROUND

[0002] Due to large-scale development and utilization of underground space and increasing extreme rainfall events in cities, the probability of underground space being flooded by floods gradually increases, and currently many cities have been flooded by underground space due to extreme rainfall events and caused huge property losses. As a semi-closed underground space, the subway has a high risk of waterlogging when heavy rain or flood occurs. Therefore, accurately calculating rainfall intensity is very important for timely drainage, predicting waterlogging risk and preventing flooding.

[0003] The existing method is to obtain the corresponding rainfall intensity through weather forecast information, but the range of weather forecast is wide, and the average rainfall intensity of a city or a region is basically calculated. For subway stations, different subway stations are located in different geographical positions, so the rainfall intensity calculated by the weather forecast method is not accurate.

[0004] In order to accurately calculate the corresponding rainfall intensity of each subway station, the existing method sets a float ball and a liquid level sensor or a transmitter in each corresponding water collecting pit of each subway station to monitor the water level change in real time, and judges the outdoor rainfall intensity through the water level change.

[0091] In order to make the purposes, technical solutions and advantages of the present application clearer, the following further describes specific embodiments of the present application with reference to the drawings. It can be understood that the specific embodiments described herein are merely used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only parts related to the present application are shown in the drawings, but not all. Before discussing the example embodiments in more detail, it should be mentioned that some example embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the operations (or steps) as sequential processes, many of the operations can be implemented in parallel, concurrently or simultaneously. In addition, the order of the operations can be rearranged. The processes can be terminated when the operations are completed, but can also have additional steps not included in the drawings. The processes can correspond to methods, functions, procedures, subroutines, subprograms, etc.

[0092] The rainfall intensity statistical analysis method, device, equipment and storage medium provided by the present application can calculate the corresponding second rainfall intensity value through the existing water pump equipment during rainfall intensity statistical analysis, thereby avoiding the problem of high cost caused by the increase of other equipment in the rainfall intensity statistical process of the subway station, reducing the cost investment of the rainfall intensity statistical analysis of the subway station; based on the irregular shape of the water collecting pit of the subway air shaft, the first rainfall intensity value obtained by calculating and processing the water pump operation data has higher accuracy than the accumulated water amount measured by the existing liquid level sensor, so as to improve the accuracy of rainfall intensity statistical analysis. Compared with the traditional rainfall intensity statistical method, the corresponding rainfall intensity is usually obtained through the information of weather forecast, but the range of weather forecast is wide, and the rainfall intensity of a city or a region is basically statistical. For subway stations, different subway stations are located in different geographical positions, so the rainfall intensity statistical by the weather forecast method is not accurate. In order to accurately predict the corresponding rainfall intensity of each subway station, the existing method sets a water ball and a liquid level sensor in each water collecting pit corresponding to each subway station to monitor the water level change in real time, and judges the outdoor rainfall intensity through the water level change. This method needs to install a set of liquid level sensor related hardware equipment for each water collecting pit of each station, which needs a large cost investment. Based on this, the rainfall intensity statistical analysis method of the present application is provided to solve the problem of high cost investment of the rainfall intensity statistical analysis of the existing subway station.

[0093] Figure 1A flowchart of a rainfall intensity statistical analysis method provided in the embodiment is shown. The rainfall intensity statistical analysis method provided in the embodiment can be executed by a rainfall intensity statistical analysis device. The rainfall intensity statistical analysis device can be implemented by software and / or hardware. The rainfall intensity statistical analysis device can be composed of two or more physical entities, or one physical entity. Generally, the rainfall intensity statistical analysis device can be a terminal device, such as a computer device.

[0094] The following describes a computer device as an example of a subject executing the rainfall intensity statistical analysis method. Referring to Figure 1 The rainfall intensity statistical analysis method is used for an intelligent monitoring terminal of a building. The building is provided with air shafts. Each group of air shafts is provided with a sump pit. Each sump pit is provided with at least one water pump group. The air shafts are open to the air. Each group of air shafts can be one air shaft or multiple air shafts. The rainfall intensity statistical analysis method specifically includes the following steps.

[0095] S101, obtaining water pump operation data corresponding to each group of air shafts and a rain receiving cross-sectional area of the air shafts.

[0096] The water pump operation data can be understood as point information of water pump operation, including water pump name, water pump start time, water pump stop time, sump pit ID, and air shaft ID, etc. It should be noted that generally, each sump pit is provided with two water pumps, one is a high liquid level water pump, and one is a low liquid level water pump. When the liquid level reaches the start-up liquid level of the corresponding water pump, the corresponding water pump starts. Specifically, which one of the two water pumps is the high liquid level water pump and which one is the low liquid level water pump is not fixed. For example, when the liquid level in the sump pit reaches the low start-up liquid level, the water pump that starts is the low liquid level water pump. After the low liquid level water pump starts, if the drainage capacity is insufficient, the liquid level continues to rise. When the liquid level reaches the high start-up liquid level, the water pump that starts is the high liquid level water pump.

[0097] It should be noted that in the embodiment, the low liquid level water pump is referred to as the first water pump, and the high liquid level water pump is referred to as the second water pump. The first water pump and the second water pump only represent the start-up order of the water pumps, and do not represent the number of the water pumps.

[0098] In addition to the foregoing water pump operation data, the rain receiving cross-sectional area of the air shafts also needs to be obtained. Figure 2 is a schematic diagram of an air shaft provided in the embodiment. Referring to Figure 2The wind shaft 10 in the present example is an open wind shaft. When it rains, rainwater can flow into the wind shaft 10. A water collecting pit 20 is arranged at the bottom of the wind shaft 10 to collect the rainwater. At least one water pump (not shown in the figure) is arranged in the water collecting pit 20. Usually, two water pumps are arranged, one is a high liquid level water pump (i.e. a second water pump), and the other is a low liquid level water pump (i.e. a first water pump). When the liquid level reaches the starting liquid level of the corresponding water pump, the corresponding water pump starts to discharge the rainwater in the water collecting pit 20. As shown in Figure 2 The rain-receiving cross-sectional area of the wind shaft 10 can be obtained according to the length and width of the inside of the wind shaft 10, i.e. S = L x D, wherein S represents the rain-receiving cross-sectional area of the wind shaft 10, L represents the length of the wind shaft 10, and D represents the width of the wind shaft 10. It should be noted that the rain-receiving cross-sectional area of the wind shaft 10 represents the catchment area of the wind shaft.

[0099] It should be noted that the shape of the water collecting pit can be irregular. The accumulated water amount obtained by measuring the change in liquid level by the liquid level meter is not accurate when the shape of the water collecting pit is irregular, i.e. the water collecting pit can be wide at the top and narrow at the bottom or narrow at the top and wide at the bottom, etc. The accumulated water amount obtained by the water pump operation data in the present embodiment is more accurate than the accumulated water amount obtained by the liquid level meter.

[0100] As described above, the water pump operation data corresponding to each group of wind shafts can be obtained according to the operation process data of the existing water pump equipment. The rain-receiving cross-sectional area of each group of wind shafts can be obtained according to the length and width of the corresponding wind shaft. The water pump operation data of the existing water pump equipment and the rain-receiving cross-sectional area of the corresponding wind shaft are used to predict the rainfall intensity, which saves the cost input and improves the accuracy.

[0101] S102, calculate the first rainfall intensity value in the corresponding calculation period according to the water pump operation data, wherein the first rainfall intensity value is the total amount of rain in the wind shaft per unit time.

[0102] The water pump operation state of each group of air shafts in a corresponding calculation period is determined according to the water pump operation data, and the water pump operation state includes a single-pump start-stop state, a double-pump start-stop state or a double-pump continuous operation state. The single-pump start-stop state can be understood as that when the liquid level in the sump reaches the low start-up liquid level, drainage is performed by the first water pump, and the drainage capacity of the first water pump is sufficient to reduce the liquid level in the sump. When the liquid level in the sump is reduced to zero, i.e., the water in the sump is drained, the first water pump stops operating. The double-pump start-stop state can be understood as that when the liquid level in the sump reaches the low start-up liquid level, drainage is performed by the first water pump, and the drainage capacity of the first water pump is insufficient to reduce the liquid level in the sump. As the liquid level in the sump rises, until the liquid level reaches the high start-up liquid level, the second water pump starts to work. At this time, the second water pump and the first water pump jointly perform drainage. Due to the addition of the second water pump, the drainage capacity is increased, so that the liquid level in the sump is reduced. When the liquid level is reduced to the low start-up liquid level, the second water pump is turned off, i.e., the second water pump stops operating. When the liquid level is reduced to zero, i.e., the water in the sump is drained, the first water pump is turned off, i.e., the first water pump stops working. The double-pump continuous operation state can be understood as that when the liquid level in the sump reaches the low start-up liquid level, drainage is performed by the first water pump, and the drainage capacity of the first water pump is insufficient to reduce the liquid level in the sump. As the liquid level in the sump rises, until the liquid level reaches the high start-up liquid level, the second water pump starts to work. At the same time, the liquid level in the sump continues to be above the low start-up liquid level, so that the second water pump and the first water pump continue to work.

[0103] When the water pump operation state is the single-pump start-stop state, the water pump operation data is calculated and processed by the first calculation strategy to obtain a first rainfall intensity value in the period of the single-pump start-stop state. The first rainfall intensity value can be understood as the total amount of rainfall in the air shaft per unit time, and the unit is cubic meters per second. The drainage capacity value, the start time and the stop time of the first water pump in the period of the single-pump start-stop state can be determined according to the water pump operation data, and the corresponding rainfall time of the start time is obtained. It should be noted that the first water pump is the water pump working in the period of the single-pump start-stop state. The first time is obtained according to the time difference between the start time and the rainfall time of the first water pump. The second time is obtained according to the time difference between the start time and the stop time of the first water pump. The first rainfall intensity value in the period of the single-pump start-stop state is obtained by calculating and processing according to the first time, the second time and the drainage capacity value of the first water pump by the first calculation strategy.

[0104] It should be noted that the rainfall time can be obtained by weather forecast or rain sensor.

[0105] Exemplarily, Figure 3 is a schematic diagram of the accumulated water amount of the sump in the single-pump start-stop state provided by the embodiment of the present application, referring to Figure 3, height A1 is the low start liquid level, and height A2 is the high start liquid level. From the rain time to the first water pump start time, a first time t1 is obtained according to the time difference between the rain time t0 start and the first water pump start time t1 start, that is, t1 = t1 start-t0 start. According to the first rainfall intensity value Q1 and the first time t1, the water accumulation V1 in the sump in the time period (that is, the first time t1) is calculated and processed, that is, Q1*t1 = V1, wherein Q1 represents the first rainfall intensity value, and the unit is m 3 / s (cubic meters per second), V1 represents the water accumulation in the sump, and the unit is m 3 (cubic meters). It should be noted that, based on the fact that the stage is before the first water pump starts, the water accumulation V1 in the sump should be the water accumulation below the low start liquid level. The first rainfall intensity value Q1 is obtained according to the product of the second rainfall intensity value H1 and the rain-receiving cross-sectional area S of the corresponding air shaft, that is, Q1 = H1*S, wherein the unit of the second rainfall intensity value H1 is m / s (meters per second), and the unit of the rain-receiving cross-sectional area S of the air shaft is m 2 (square meters). From the first water pump start time to the stop time, a second time t2 is obtained according to the time difference between the start time t1 start and the stop time t1 end, that is, t2 = t1 end-t1 start. At this time, based on the fact that the rainwater is still increasing, the first water pump has already started to work, and therefore the newly added water accumulation (Q1*t2) is obtained according to the product of the first rainfall intensity value Q1 and the second time t2. Based on the fact that the first water pump stops working when the water in the sump is drained, the newly added water accumulation (Q1*t2) plus the original water accumulation V1 in the sump is equal to the total drainage amount P b1 *t2 of the first water pump in the second time, that is, Q1*t2+V1 = P b1 *t2, wherein P 3 is the drainage capacity value of the first water pump, and the unit is m b1 / s (cubic meters per second), Q1*t2 is the newly added water accumulation, and P 3 *t2 is the total drainage amount of the first water pump in the second time.

[0106] According to the above formula, a first formula is obtained. The first formula is calculated and processed to obtain the first rainfall intensity value in the single-pump start-stop state cycle; wherein Q1 represents the first rainfall intensity value in the single-pump start-stop state cycle, and the unit is m 3 / s (cubic meters per second); P b1 represents the drainage capacity value of the first water pump, and the unit is m 3 / s (cubic meters per second); t1 represents the first time, and the unit is s (second); and t2 represents the second time, and the unit is s (second).

[0107] It should be noted that the above is only a derivation process, and in the actual detection process, the first rainfall intensity value Q1 and the second rainfall intensity value H1 are unknown values, and based on the above derivation, the first formula is used for calculation and processing to obtain the first rainfall intensity value Q1 in the cycle of the single-pump start-stop state. That is, the drainage capacity value P b1 of the first water pump, the first time t1 and the second time t2 are used for calculation and processing to obtain the first rainfall intensity value Q1 in the cycle of the single-pump start-stop state.

[0108] When the water pump operating state is the double-pump start-stop state, the water pump operating data is calculated and processed by the second calculation strategy to obtain the first rainfall intensity value in the cycle of the double-pump start-stop state. The drainage capacity value of the first water pump, the start time and the stop time of the first water pump, and the drainage capacity value of the second water pump, the start time and the stop time of the second water pump can be determined according to the water pump operating data. It should be noted that the first water pump is the water pump started first, that is, the low liquid level water pump; the second water pump is the water pump started later, that is, the high liquid level water pump. The third time is obtained according to the time difference between the start time of the first water pump and the start time of the second water pump, and the fourth time is obtained according to the time difference between the start time and the stop time of the second water pump. The third time, the fourth time, the drainage capacity value of the first water pump and the drainage capacity value of the second water pump are calculated and processed by the second calculation strategy to obtain the first rainfall intensity value in the cycle of the double-pump start-stop state.

[0109] Exemplarily, Figure 4 is a schematic diagram of the accumulated water amount of the sump in the double-pump start-stop state provided by the embodiments of the present application, referring to Figure 4 , the height A1 is the low start liquid level, and the height A2 is the high start liquid level. From the first water pump start time to the second water pump start time, the third time t3 is obtained according to the time difference between the start time t2_start of the second water pump and the start time t1_start of the first water pump, that is, t3=t2_start-t1_start. The first rainfall intensity value Q2 of the outdoor and the third time t3 are calculated and processed to obtain the new accumulated water amount (Q2*t3) in the sump in this time period. Based on the fact that only the first water pump performs the drainage work in this time period (that is, the third time t3) and the drainage capacity is insufficient, the liquid level reaches the high start liquid level A2, so the difference between the new accumulated water amount (Q2*t3) and the drainage amount of the first water pump in this time period (that is, the third time t3) is obtained, that is, the accumulated water amount difference V2 between the high start liquid level and the low start liquid level, that is, the volume between the liquid levels A1-A2, that is, Q2*t3-P b1 *t3=V2, wherein P b1*t3 represents the displacement of the first water pump in this time period (i.e. the third time t3), and the unit of V2 is m 3 (cubic meters). It should be noted that the second water pump stops working when the liquid level drops to the low starting liquid level A1. The first rainfall intensity value Q2 is obtained by multiplying the second rainfall intensity value H2 in the cycle of the dual pump start-stop state and the rain-receiving cross-sectional area S of the corresponding wind shaft, that is, Q2=H2*S, where the unit of the second rainfall intensity value H2 is m / s (meters / second), and the unit of the rain-receiving cross-sectional area S of the wind shaft is m 2 (square meters). From the start time of the second water pump to the stop time of the second water pump, the fourth time t4 is obtained according to the difference between the stop time t2_end and the start time t2_start of the second water pump, that is, t4=t2_end-t2-start. The newly accumulated water volume (Q2*t4) in the sump during this time period is obtained by calculation based on the first outdoor rainfall intensity value Q2 and the fourth time t4. Based on the fact that the second water pump stops working when the liquid level drops to the low starting liquid level A1, the newly accumulated water volume (Q2*t4) plus the difference V2 between the high starting liquid level and the low starting liquid level is the same as the total drainage volume of the first water pump and the second water pump during this time period (that is, the fourth time t4), that is, Q2*t4+V2=(P b1 +P b2 )*t4, where P b1 Represents the drainage capacity of the first water pump, P b2 represents the drainage capacity value of the second water pump, t3 represents the third time, t4 represents the fourth time, (P b1 +P b2 )*t4 represents the total weight of water discharged by the first water pump and the second water pump at the fourth time t4.

[0110] Combining the above formulas, we can get the third formula Through the third formula Calculation is performed to obtain the first rainfall intensity value within the period of dual pump start-stop state; wherein Q2 represents the first rainfall intensity value within the period of dual pump start-stop state, in units of m 3 / s (cubic meter / second); P b1 Represents the drainage capacity of the first water pump, in m 3 / s (cubic meter / second); P b2 Represents the drainage capacity of the second water pump, in m 3 / s (cubic meter / second); t3 represents the third time, the unit is s (second); t4 represents the fourth time, the unit is s (second).

[0111] It should be noted that the above is only a derivation process. In the actual detection process, the first rainfall intensity value Q2 and the second rainfall intensity value H2 are both unknown values. Based on the above derivation, the third formula can be used to calculate the rainfall intensity. The calculation processing is performed to obtain the first rainfall intensity value Q2 in the period corresponding to the double-pump start-stop state. That is, the first rainfall intensity value Q2 in the period corresponding to the double-pump start-stop state can be calculated according to the drainage capacity value P b1 of the first water pump b2 , the drainage capacity value P of the second water pump , the third time t3 and the fourth time t4.

[0112] When the water pump operating state is the double-pump continuous operating state, the third calculation strategy is used to perform the calculation processing on the water pump operating data to obtain the first rainfall intensity value in the period corresponding to the double-pump continuous operating state. The drainage capacity value of the first water pump, the start time of the first water pump and the start time of the second water pump in the period corresponding to the double-pump continuous operating state can be determined according to the water pump operating data. It should be noted that the first water pump is the water pump started first, that is, the low-liquid-level water pump; the second water pump is the water pump started later, that is, the high-liquid-level water pump. The fifth time is obtained according to the difference between the start time of the first water pump and the start time of the second water pump in the period corresponding to the double-pump continuous operating state. The second rainfall intensity value in the period corresponding to the previous double-pump start-stop state, the start time of the first water pump and the start time of the second water pump are obtained. The second rainfall intensity value in the period corresponding to the previous double-pump start-stop state can be obtained by using the calculation strategy in the period corresponding to the double-pump start-stop state, and the start time of the first water pump and the start time of the second water pump in the period corresponding to the previous double-pump start-stop state are obtained according to the water pump operating data. The third time is obtained according to the difference between the start time of the first water pump and the start time of the second water pump in the period corresponding to the previous double-pump start-stop state. The first rainfall intensity value in the period corresponding to the double-pump continuous operating state is obtained according to the second rainfall intensity value in the period corresponding to the previous double-pump start-stop state, the third time, the drainage capacity of the first water pump in the period corresponding to the double-pump continuous operating state and the fifth time.

[0113] It should be noted that the second rainfall intensity value is the rainfall depth per unit area per unit time, and the unit is meter / second.

[0114] For example, with reference to Figure 4, the third time t3 is obtained according to the time difference between the starting time t2_start of the second water pump and the starting time t1_start of the first water pump, that is, t3 = t2_start-t1_start. The new water accumulation amount (Q2*t3) in the sump in this period is calculated and processed according to the first rainfall intensity value Q2 outdoors and the third time t3. Based on the fact that only the first water pump is working for drainage in this period (that is, the third time t3) and the drainage capacity is insufficient, the liquid level reaches the high starting liquid level A2. Therefore, according to the difference between the new water accumulation amount (Q2*t3) and the drainage amount of the first water pump in this period (that is, the third time t3), the water accumulation amount difference V2 between the high starting liquid level and the low starting liquid level is obtained, that is, the volume between the liquid levels A1-A2, that is, Q2*t3-P b1 *t3=V2, wherein P b1 *t3 represents the drainage amount of the first water pump in this period (that is, the third time t3), and V2 has the unit of m 3 (cubic meters). The first rainfall intensity value Q2 is obtained according to the product of the second rainfall intensity value H2 and the rain-receiving cross-sectional area S of the air shaft, that is, Q2=H2*S, wherein the unit of the second rainfall intensity value H2 is m / s (meters / second), and the unit of the rain-receiving cross-sectional area S of the air shaft is m 2 (square meters). In the period of the dual-pump continuous running state, the fifth time t5 is obtained according to the time difference between the starting time of the second water pump and the starting time of the first water pump, and the new water accumulation amount (Q3*t5) in the sump in this period is calculated and processed according to the first rainfall intensity value Q3 outdoors and the fifth time t5. Based on the fact that only the first water pump is working for drainage in this period (that is, the fifth time t5) and the drainage capacity is insufficient, the liquid level reaches the high starting liquid level A2. Therefore, according to the difference between the new water accumulation amount (Q3*t5) and the drainage amount of the first water pump in this period (that is, the fifth time t5), the water accumulation amount difference V2 between the high starting liquid level and the low starting liquid level is obtained, that is, the volume between the liquid levels A1-A2, that is, Q3*t5-P b1 ’*t5=V2, wherein P b1 ’ represents the drainage capacity value of the first water pump in the period of the dual-pump continuous running state, and P b1 ’*t5 represents the drainage amount of the first water pump in this period (that is, the fifth time t5), and V2 has the unit of m 3(m / s). The first rainfall intensity value Q3 is obtained according to the product of the second rainfall intensity value H3 in the period of the double-pump continuous operation state and the rain-receiving cross-sectional area S of the corresponding air shaft, that is, Q3 = H3 * S, wherein the unit of the second rainfall intensity value H3 is m / s (meter / second), and the unit of the rain-receiving cross-sectional area S of the air shaft is m 2 (m / s).

[0115] According to the above formula, the fifth formula can be obtained The first rainfall intensity value in the period of the double-pump continuous operation state is obtained by performing calculation processing according to the fifth formula ; wherein Q3 represents the first rainfall intensity value in the period of the double-pump continuous operation state, and the unit is m 3 / s (cubic meter / second); P b1 represents the drainage capacity value of the first water pump, and the unit is m 3 / s (cubic meter / second); P b1 ' represents the drainage capacity value of the first water pump in the period of the previous double-pump start-stop state, and the unit is m 3 / s (cubic meter / second); t3 represents the third time, and the unit is s (second); t5 represents the fifth time, and the unit is s (second); H2 represents the second rainfall intensity value in the period of the previous double-pump start-stop state, and the unit is m / s (meter / second); and S represents the rain-receiving cross-sectional area of the air shaft, and the unit is m 2 (m / s).

[0116] It should be noted that the above is only a derivation process, and in the actual detection process, the first rainfall intensity value Q3 and the second rainfall intensity value H3 are unknown values. Based on the above derivation, the corresponding first rainfall intensity value Q3 in the period of the double-pump continuous operation state can be obtained by performing calculation processing according to the fifth formula ; that is, the first rainfall intensity value Q3 in the period of the double-pump continuous operation state can be obtained by performing calculation processing according to the drainage capacity value P b1 of the first water pump, the drainage capacity value P b1 ' of the first water pump in the period of the previous double-pump start-stop state, the third time t3, the fifth time t5, and the rain-receiving cross-sectional area S of the air shaft.

[0117] According to the above, the corresponding first rainfall intensity value in different water pump operation states can be obtained through the water pump operation data, so that the subsequent calculation of the second rainfall intensity value can be performed according to the first rainfall intensity value. The rainfall intensity can be predicted based on the existing water pump equipment, thereby avoiding the increase in cost caused by the need for additional investment in other equipment, thereby reducing the cost investment of rainfall prediction. In addition, the rainfall at each air shaft position point is predicted through the air shaft, thereby improving the fineness of the prediction position point and improving the accuracy of the rainfall intensity statistics.

[0118] S103、According to the first rainfall intensity value and the corresponding rain receiving cross-sectional area, the second rainfall intensity value of each group of air shaft position points in the corresponding calculation period is calculated, and the second rainfall intensity value is the rainfall depth per unit area per unit time.

[0119] When the water pump operating state is a single pump start-stop state, the first rainfall intensity value Q1 in the cycle of the single pump start-stop state can be calculated by the first formula The first rainfall intensity value Q1 is calculated and processed with the rain receiving cross-sectional area S of the air shaft to obtain the second rainfall intensity value H1 of the corresponding air shaft position points in the cycle of the single pump start-stop state. For example, the second formula is used for calculation and processing to obtain the second rainfall intensity value of the corresponding air shaft position points in the cycle of the single pump start-stop state, wherein H1 represents the second rainfall intensity value in the cycle of the single pump start-stop state, and the unit is m / s (meter / second); S represents the rain receiving cross-sectional area of the air shaft, and the unit is m 2 (square meter). In the cycle of the single pump start-stop state, the second rainfall intensity value of each group of air shaft position points in the cycle of the single pump start-stop state is obtained by the above calculation strategy, and the accuracy of rainfall intensity statistics is higher than that of the existing weather forecast method. In addition, the prediction of rainfall intensity can be completed by the existing water pump equipment in each group of air shafts, and the cost investment of the present example is lower than that of the existing method which needs to increase the liquid level device.

[0120] When the water pump operating state is a double pump start-stop state, the first rainfall intensity value Q2 in the cycle of the double pump start-stop state can be calculated by the third formula The first rainfall intensity value Q2 is calculated and processed with the rain receiving cross-sectional area S of the air shaft to obtain the second rainfall intensity value H2 of the corresponding air shaft position points in the cycle of the double pump start-stop state. For example, the fourth formula is used for calculation and processing to obtain the second rainfall intensity value of the corresponding air shaft position points in the cycle of the double pump start-stop state; wherein H2 represents the second rainfall intensity value in the cycle of the double pump start-stop state, and the unit is m / s (meter / second); S represents the rain receiving cross-sectional area of the air shaft, and the unit is m 2 (square meter). In the cycle of the double pump start-stop state, the second rainfall intensity value of each group of air shaft position points in the cycle of the double pump start-stop state is obtained by the above calculation strategy, and the accuracy of rainfall intensity statistics is higher than that of the existing weather forecast method. In addition, the prediction of rainfall intensity can be completed by the existing water pump equipment in each group of air shafts, and the cost investment of the present example is lower than that of the existing method which needs to increase the liquid level device.

[0121] When the water pump operating state is a double pump continuous operation state, the first rainfall intensity value Q3 in the cycle of the double pump continuous operation state can be calculated by the fifth formula The first rainfall intensity value Q3 in the period of the double-pump continuous running state can be calculated. The first rainfall intensity value Q3 is calculated with the rain-receiving cross-sectional area S of the air shaft to obtain the corresponding second rainfall intensity value H3 of the air shaft position point in the period of the double-pump continuous running state. For example, the sixth formula is used to calculate and process to obtain the corresponding second rainfall intensity value of the air shaft position point in the period of the double-pump continuous running state; wherein H3 represents the second rainfall intensity value in the period of the double-pump continuous running state, and the unit is m / s (meter / second); S represents the rain-receiving cross-sectional area of the air shaft, and the unit is m 2 (square meter). In the period of the double-pump continuous running state, the second rainfall intensity value corresponding to each group of air shaft position points in the period of the double-pump continuous running state is obtained through the above calculation strategy. Compared with the existing weather forecasting method, the accuracy of rainfall intensity statistics is higher. In addition, the prediction of rainfall intensity can be completed by the existing water pump equipment in each group of air shafts. Compared with the existing method of increasing the liquid level device, the cost of the present example is lower.

[0122] In an embodiment, the above calculation strategy can be integrated into a rainfall intensity statistical model. The corresponding water pump running data and configuration information are input into the rainfall intensity statistical model for data processing. In the rainfall intensity statistical model, the calculation period of the single-pump start-stop state, the double-pump start-stop state, or the double-pump continuous running state corresponding to the water pump running data is processed, and the real-time rainfall intensity threshold is output. The configuration information includes the sump ID, the air shaft ID, the water pump equipment number, and the drainage capacity of the water pump. The information output by the rainfall intensity statistical model includes the second rainfall intensity value and whether to alarm. The second rainfall intensity value obtained by calculation is compared with the preset range corresponding to the preset rainfall intensity level to determine the corresponding rainfall grade. The specific preset rainfall intensity level corresponding to the preset range is as follows:

[0123] H (mm / h) Rainfall classification 0.1-9.9 Light rain 10.0-24.9 Moderate rain 25-49.9 Heavy rain 50-99.9 Violent rain 100-249.9 Very violent rain >＝250 Extra violent rain

[0124] It should be noted that the unit of the second rainfall intensity value (H1, H2, or H3) obtained by the foregoing embodiments is m / s (meter / second). When the rainfall grade is divided, the unit of the second rainfall intensity value (H1, H2, or H3) can be converted to mm / h (millimeter / hour) according to the actual situation.

[0125] According to the division of the rainfall grade, the alarm level is determined. When the second rainfall intensity value reaches the alarm level or above, an alarm is given. For example, assuming that the alarm level is determined to be heavy rain, when the second rainfall intensity value is heavy rain, heavy rain, or torrential rain, an alarm is given.

[0126] In an embodiment, when the water pump running state is the double-pump continuous running state, when the high water level state information is continuously not eliminated, according to the continuous running time length (for example, continuous running for 15 minutes) or the calculated result is then an alarm is given.

[0127] In an embodiment, when the water pump running state is the double-pump start-stop state, the time from single-pump start to double-pump start is calculated according to historical data, and if it is less than a threshold TM, it indicates that the water inflow speed exceeds the water pump drainage speed, and an alarm is given. It should be noted that the threshold TM can be set according to actual conditions. For example, the threshold TM can be set to the historical average value.

[0128] According to the above, by using the water pump running data and combining the information of the sump and the air shaft, the outdoor second rainfall intensity value corresponding to each group of air shaft position points can be calculated. Compared with the second rainfall intensity value obtained by the existing weather forecast method, the second rainfall intensity value predicted by the embodiment can be accurate to each group of air shafts, that is, it can be accurate to the second rainfall intensity value of the surrounding area of the subway station level, and the granularity is smaller, thereby improving the accuracy of rainfall intensity statistics. In addition, compared with the existing prediction method through additional hardware devices such as liquid level meters, the second rainfall intensity value corresponding to the existing water pump running data, air shafts, and sump information can be obtained, thereby avoiding the increase in cost caused by the addition of other devices, thereby reducing the cost investment of rainfall intensity statistics.

[0129] According to the above, by calculating and processing the water pump running data corresponding to each group of air shaft sumps and the rain-receiving cross-sectional area of the corresponding air shaft, the second rainfall intensity value in the calculation period corresponding to each group of air shaft position points is obtained. By using the above technical means, the corresponding second rainfall intensity value can be calculated through the existing water pump equipment, thereby avoiding the problem of high cost caused by the addition of other devices in the process of rainfall intensity statistics of the subway station, thereby reducing the cost investment of rainfall intensity statistics of the subway station. In addition, based on the irregular shape of the sump of the subway air shaft, the first rainfall intensity value in the corresponding calculation period obtained by calculating and processing the water pump running data has higher accuracy than the accumulated water amount measured by the existing liquid level meter, thereby improving the accuracy of rainfall intensity statistical analysis.

[0130] On the basis of the above embodiment, Figure 5 is a structural schematic diagram of a rainfall intensity statistical analysis device provided by the embodiment of the present application.
