Description

Technical Field

[0001] The present application relates to the technical field of underground building waterproofing and flood discharge, and in particular to an underground building waterproofing and flood discharge method and system. Background Art

[0002] Flood discharge is simply "flood discharge". Due to continuous heavy rainfall in the upper reaches, the reservoir exceeds a certain water level (flood limit water level). In order to avoid flooding or the collapse of reservoir dams and dikes and cause serious disasters, the floodgates are opened to discharge floodwaters to the downstream river to ensure the safety of the reservoir dam. The flood discharge we often talk about is generally ground flood discharge, but due to the expansion of construction in recent years, there are more and more underground buildings. According to the water flow trend of "water flows to lower places", underground buildings are more likely to accumulate water, leading to disasters such as floods, which bring inconvenience to people.

[0003] In the related art, underground buildings are only equipped with drainage outlets and use an integrated drainage system. However, the degree of water accumulation in underground buildings is affected by the environment and the degree of danger is also different. Using one flood discharge plan in all situations will not only lead to unsatisfactory flood discharge, but also waste resources. There is room for improvement.

[0004] To this end, we propose an underground building waterproof flood discharge method and system to solve the above problems. Summary of the invention

[0017] According to the regional data, the number of drainage outlets and the drainage outlet speed in the region are obtained to obtain drainage speed data;

[0018] According to the area data and the drainage speed data, the water levels of different areas are detected, and the water level information of different areas is recorded to obtain the water level data.

[0031] Based on the obstacle data, a negative correlation curve between the number of obstacles and the drainage speed of the drain outlet is obtained, the drainage speed of the drain outlet is obtained according to the curve analysis, and the water level height is calculated according to the drainage speed to obtain the obstacle data;

[0032] The water level height data is obtained by superimposing the water level height change caused by the water flow velocity according to the blocking data and the high-level water level height data.

[0033] Through the above technical solution, the garbage content in the accumulated water can be analyzed to determine whether the drain outlet is blocked, thereby analyzing the drainage speed of the drain outlet. At the same time, according to the size of the water flow, the situation where the building is destroyed by the accumulated water and the drain outlet is blocked for drainage can be analyzed to obtain an accurate drainage speed, which is conducive to confirming the water level and improving the practicality of underground building waterproofing and flood discharge.

[0034] Preferably, the step of obtaining the crowd situation in the underground building according to the water level data, analyzing the personal injuries caused, and obtaining the personal danger degree data specifically includes the following steps:

The damage caused by accumulated water to people is analyzed, which improves the safety of waterproof flood discharge in underground buildings.

[0040] Preferably, the step of analyzing the time and degree of casualties caused by the water level to the crowd, analyzing the degree of danger, and obtaining the data on the degree of personal danger according to the casualty probability data further includes the following steps:

[0041] Based on the casualty probability data, a positive correlation curve between casualty time and danger level is obtained, and the danger level corresponding to the casualty time is analyzed to obtain first danger data;

[0042] According to the first danger data and the water level data, the water pressure is calculated according to the water level, a positive correlation curve between the water pressure pressure and the danger level is obtained, and the danger level corresponding to the water pressure is analyzed to obtain the second danger data;

[0043] Based on the second danger data and the garbage data, the bacteria content in the garbage is calculated, a positive correlation curve between the bacteria content and the danger level is obtained, and the danger level corresponding to the bacteria content is analyzed to obtain the third danger data;

[0044] According to the third hazard data, the material properties of the underground building are obtained, the toxicity of the substances emitted by the building when it comes into contact with water is analyzed, a proportional coefficient between the toxicity of the substance and the degree of hazard is established, the degree of hazard corresponding to the toxicity of the substance is obtained, and the personal hazard degree data is obtained.

[0045] By adopting the above technical scheme, combined with the pressure of water level, the bacterial content caused by garbage and the toxic substances emitted by buildings, a more accurate degree of harm to the human body can be obtained through multi-faceted analysis of the damage caused by accumulated water to the human body, thereby improving the accuracy of waterproofing and flood discharge of underground buildings.

[0046] Preferably, the step of calculating the economic loss caused by the water level based on the personal danger degree data, analyzing the flood danger degree according to the economic loss, and obtaining the danger data specifically includes the following steps:

[0047] Based on the water level data, underground building materials submerged by the water level are obtained, and the loss of the building materials due to waterlogging is calculated to obtain first loss data;

[0048] According to the first loss data, obtain the items in the building submerged by the water level, calculate the emergency loss caused according to the loss degree of the items, and obtain the second loss data;

[0049] Based on the second loss data, a positive correlation curve between the loss degree and the risk degree is obtained, and the corresponding risk degree is matched according to the positive correlation curve between the loss degree and the risk degree to obtain economic risk degree data;

[0050] According to the personal danger level data and the economic danger level data, a weight ratio is set, and the overall flood danger level is comprehensively calculated to obtain the danger data.

[0051] By adopting the above technical solution, the economic losses caused by waterlogging are calculated using the losses of buildings and items in underground buildings, and the degree of economic danger is obtained. Combined with the degree of personal danger, the total degree of danger caused by waterlogging is calculated, which is conducive to the subsequent determination of flood discharge plans and improves the practicality of underground building waterproof flood discharge.

[0052] Preferably, the step of setting a weight ratio according to the personal danger degree data and the economic danger degree data, comprehensively calculating the overall flood danger degree, and obtaining the danger data further includes the following steps:

[0053] Based on the personal danger level data, the lowest value and the highest value of the personal danger level are obtained, the lowest value of the personal danger level corresponds to a weight ratio of 0, and the highest value of the personal danger level corresponds to a weight ratio of 100%, and a weight ratio curve is generated;

[0054] Based on the weight ratio curve and the personal danger degree data, matching the weight ratio corresponding to the personal danger degree, calculating the overall danger degree according to the weight ratio, and obtaining the personal danger data;

[0055] Based on the weight ratio curve, the difference between the weight ratio of the personal danger degree and 100% is obtained, and the difference between the weight ratio of the personal danger degree and 100% is the weight ratio of the economic danger degree data, and the economic weight ratio data is obtained;

[0056] Based on the economic weight ratio data and the economic risk degree data, the overall risk degree caused by the economic risk is calculated using the weight ratio to obtain the economic risk data;

[0057] The personal danger data and the economic danger data are combined and superimposed to obtain the danger data.

[0058] By adopting the above technical solution and setting different weight ratios, when the degree of personal danger is serious, economic losses are not considered and personal safety is given priority. Using different weight ratios for calculation in different scenarios is conducive to obtaining a more accurate degree of danger and improving the safety of underground building waterproofing and flood discharge.

[0059] Preferably, the step of calculating the flood discharge speed based on the flood discharge time data, matching the corresponding flood discharge power, starting the flood discharge system to perform flood discharge work, and obtaining the flood discharge data further includes the following steps:

[0060] Based on the flood discharge time data, a safe water level value is set, and according to the change of water level height at different times, the discharge water volume to reach the safe water level is calculated to obtain water volume data;

[0061] Based on the water volume data and the flood discharge time data, the flood discharge speed is calculated using a speed formula to obtain flood discharge speed data;

[0062] According to the flood discharge speed data, a comparison table of flood discharge system power and flood discharge speed is obtained, and the corresponding equipment power is matched according to the comparison table to obtain flood discharge power data;

[0063] Based on the flood discharge power data, the flood discharge system is started to perform flood discharge work according to the corresponding flood discharge power to obtain the flood discharge data.

[0064] By adopting the above technical solution, different flood discharge speeds are set according to different water content, and the corresponding flood discharge power is activated according to the flood discharge speed, which reduces the occurrence of high-power flood discharge when there is a small amount of water accumulation. Different flood discharge powers are more suitable for different scenarios, energy-saving and environmentally friendly, and improve the energy saving of underground building waterproof flood discharge.

[0065] In the second aspect, the present application provides an underground building waterproof flood discharge system, which adopts the following technical solution:

[0066] A waterproof flood discharge system for underground buildings comprises a detection module, an analysis module, a calculation module and an execution module, wherein the detection module is used to detect water level height and flood-related parameters and output water level data; the analysis module is connected to the detection module by signal, and is used to receive the water level data and output danger data after analyzing the danger degree; the calculation module is connected to the analysis module by signal, and is used to receive the danger data and output speed data after calculating the flood discharge speed; the execution module is connected to the calculation module by signal, and is used to receive the speed data and perform flood discharge work according to a preset speed.

[0067] Through the above technical solution, the electronic module is used to achieve waterproof flood discharge, which can reduce the tediousness of manual operation on the one hand, and can carry out different flood discharge plans according to the actual water accumulation scene on the other hand. The use of electronic modules improves the convenience of waterproof flood discharge in underground buildings.

[0068] In summary, the present application includes at least one of the following beneficial technical effects:

[0069] 1. According to the actual danger level of water accumulation, the corresponding flood discharge power is matched, which can be applied to more water accumulation scenarios, reduce casualties and economic losses, and use the least energy for flood discharge, thereby improving the practicality and energy saving of underground building waterproof flood discharge.

[0070] 2. Combining meteorological information and drainage speed, the water level can be analyzed. At the same time, the building area and precipitation can be used to accurately calculate the change in water level.

[0081] Below is a combination of the embodiments and the attached Figure 1-9 The present invention is further described in detail, but the embodiments of the present invention are not limited thereto.

[0082] Example:

[0083] The present invention discloses a method for flood discharge of underground buildings, referring to Figure 1 , specifically including the following steps:

[0084] Step S1, obtaining a 3D model of an underground building, detecting water levels in different areas of the underground building, and obtaining water level data.

[0085] Step S2, based on the water level data, obtain meteorological information, analyze the water level change height according to the meteorological information, and obtain water level height data.

[0086] Step S3, obtaining the crowd situation in the underground building based on the water level data, analyzing the personal injuries caused, and obtaining personal danger degree data.

[0087] Step S4, based on the personal danger degree data, calculate the economic loss caused by the water level, analyze the flood danger degree according to the economic loss, and obtain danger data.

[0088] Step S5, based on the danger data, establish a negative correlation curve between the danger level and the flood discharge time, match the corresponding flood discharge time according to the negative correlation curve between the danger level and the flood discharge time, and obtain the flood discharge time data.

[0089] Step S6, based on the flood discharge time data, calculate the flood discharge speed, match the corresponding flood discharge power, start the flood discharge system to perform flood discharge work, and obtain flood discharge data.

[0090] In actual use, underground buildings are below the water level, so it is easy to accumulate water when it rains. If not handled properly, it will lead to excessive accumulation of water and cause flood disasters. The use of the flood discharge system requires manual activation on the one hand, and the fixed flood discharge power is not suitable for all scenarios on the other hand. Discharging flood water according to actual conditions is more energy-saving and environmentally friendly, and can also adapt to multiple scenarios. For example, the water level of the underground garage is 1 cm. At this time, when the flood discharge system is draining, the power can be smaller, the water is less, and the water can be drained quickly. However, when the water level is 50 cm, there is a lot of water, and it is difficult to drain it in a short time, so the drainage speed needs to be increased.

[0091] Reference Figure 2 , obtaining a 3D model of an underground building, detecting water levels in different areas of the underground building, and obtaining water level data, specifically includes the following steps:

[0092] Step S11, obtaining a 3D model of the underground building, dividing the underground building into regions according to height, and obtaining preliminary regional data.

[0093] Step S12, based on the preliminary regional data, for areas at the same height, the areas are divided according to the number of drainage outlets in the water flow direction in the area, and the areas with the same and continuous number of drainage outlets are divided into the same area to obtain regional data.

[0094] Step S13, according to the regional data, the number of drainage outlets and the drainage outlet speed in the area are obtained to obtain drainage speed data.

[0095] Step S14, detecting the water levels of different areas according to the area data and the drainage speed data, recording the water level information of different areas, and obtaining the water level data.

[0096] In actual use, underground buildings often have multiple drainage outlets to drain multiple areas. Because of the wall blocking between different areas and the inconsistent number of drainage outlets, the drainage speed of different areas will be inconsistent, resulting in inconsistent water levels in different areas. If all underground buildings are connected, the water level of the underground buildings will be consistent. Different drainage plans based on the water level in different areas are conducive to more rational use of resources. For example, the water level in area A is 50 cm, and the drainage speed of the flood discharge system in area A should be faster. The water level in area B is 10 cm, the drainage speed can be slower, and the power of the drainage system can be reduced.

[0097] Reference Figure 3 The step of obtaining meteorological information based on water level data, analyzing the water level change height according to the meteorological information, and obtaining water level height data specifically includes the following steps:

[0098] Step S21, obtain meteorological information, obtain the area of ​​the underground building according to the 3D model diagram of the underground building, calculate the water level change height according to the precipitation and the area, and obtain primary water level height data.

[0099] Step S22, based on the water level data and the primary water level height data, the original water level height and the water level change height are superimposed to obtain the intermediate water level height data.

[0100] Step S23, based on the intermediate water level data and the drainage speed data, the water level height caused by drainage is subtracted from the intermediate water level data to obtain the advanced water level data.

[0101] Step S24, based on the high-level water level data, obtain the correlation curve between precipitation and time, calculate the water level at different times according to the correlation curve between precipitation and time, and obtain the water level data.

[0102] In actual use, the water level will be affected by the weather. The water level will continue to rise as it rains. The rise in water level is related to the amount of rainfall. The greater the rainfall, the faster the water level rises. The speed of flood discharge and drainage is also different under different water level changes. For example, if the water level is 50 cm, the water level can drop by one cm per minute, but the water level will rise by 1 cm per minute due to heavy rain. If the water is drained at this speed, the water level will continue to rise. Set the drainage speed to drop by 2 cm per minute, and after 50 minutes, the water level will drop to 0.

[0103] Reference Figure 4 , based on the high-level water level data, obtaining the correlation curve between precipitation and time, calculating the water level at different times according to the correlation curve between precipitation and time, and obtaining the water level data, further comprising the following steps:

[0104] Step S241, based on the high-level water level data, obtain the correlation curve between precipitation and time, calculate the water level at different times according to the correlation curve between precipitation and time, and obtain the first height data.

[0105] Step S242, according to the first height data, obtain the daily average amount of garbage and the type of garbage in the underground building to obtain garbage data.

[0106] Step S243, obtaining the water flow size according to the drainage speed data, establishing a positive correlation curve between the water flow size and the number of damaged objects, analyzing the number of damaged objects according to the curve, and obtaining damaged object data.

[0107] Step S244, combining the garbage data and the damaged object data, superimposing the garbage quantity and the damaged object quantity, obtaining the obstacle quantity, and obtaining the obstacle data.

[0108] Step S245, based on the obstacle data, obtain the negative correlation curve between the number of obstacles and the drainage speed of the drain outlet, obtain the drainage speed of the drain outlet according to the curve analysis, calculate the water level according to the drainage speed, and obtain the obstacle data.

[0109] Step S246, based on the blocking data and the high-level water level data, the water level change caused by the water flow velocity is superimposed to obtain the water level data.

[0110] In actual use, the height of the water level is not only affected by the weather, but also by the drainage speed. Before starting the flood discharge system, the water is drained through the ordinary drain outlet. Draining through the ordinary drain outlet can reduce the occurrence of unnecessary waste of resources. Some smaller water accumulation situations can also be quickly solved through the drain outlet, and there is no need to start the flood discharge system. However, the drain outlet will be blocked by garbage, causing the water flow to be discharged slowly, thus affecting the change in water level. For example, the water level is 10 cm, the drain outlet can drop 1 cm per minute through drainage, and the water level is 0 in ten minutes. But at five minutes, the drain outlet is blocked by garbage, and the water level drops by 0.5 cm per minute. Therefore, after ten minutes, the water level is 2.5 cm.

[0111] Reference Figure 5 , according to the water level data, the crowd situation of the underground building is obtained, the personal injury caused is analyzed, and the steps of obtaining the personal danger degree data specifically include the following steps:

[0112] Step S31, based on the water level data, detect the number of people in the underground building and the height range of the people to obtain crowd data.

[0113] Step S32, judging whether the water level will pose a threat to the crowd based on the water level data and the crowd data, and if the water level will not pose a threat to the crowd, it is considered that there is no personal danger.

[0114] Step S33, based on the crowd data, if the water level poses a threat to the crowd, a positive correlation curve between the number of people and the probability of casualties is obtained, and the probability of casualties of the crowd is analyzed according to the curve to obtain casualty probability data.

[0115] Step S34, based on the casualty probability data, analyzing the casualty time and degree of casualties caused by the water level to the crowd, analyzing the danger degree, and obtaining personal danger degree data.

[0116] In actual use, different water levels will cause different harm to people. The higher the water level, the more serious the harm to the human body. For example, when the water level is 1 cm, it only submerges the shoes of the crowd and does not affect the movement of the crowd, posing no threat to the crowd. However, when the water level is 1 meter, the water pressure will compress the human internal organs and may cause drowning, resulting in casualties. Therefore, different water levels cause different degrees of danger to the crowd. When it is more dangerous, the drainage speed of the flood discharge system should be faster, and the water should be drained in time to reduce casualties.

[0117] Reference Figure 6 The step of analyzing the time and extent of casualties caused by the water level to the crowd according to the casualty probability data, analyzing the danger level, and obtaining the personal danger level data also includes the following steps:

[0118] Step S341, based on the casualty probability data, obtain a positive correlation curve between the casualty time and the danger level, analyze the danger level corresponding to the casualty time, and obtain first danger data.

[0119] Step S342, based on the first danger data and the water level data, the water pressure is calculated according to the water level, a positive correlation curve between the water pressure pressure and the danger level is obtained, the danger level corresponding to the water pressure is analyzed, and the second danger data is obtained.

[0120] Step S343, based on the second danger data and the garbage data, calculate the bacteria content in the garbage, obtain a positive correlation curve between the bacteria content and the danger level, analyze the danger level corresponding to the bacteria content, and obtain the third danger data.

[0121] Step S344, based on the third hazard data, obtain the material properties of the underground building, analyze the toxicity of the substances emitted by the building when it comes into contact with water, establish a proportional coefficient between the toxicity of the substance and the degree of hazard, obtain the degree of hazard corresponding to the toxicity of the substance, and obtain the personal hazard degree data.

[0122] In actual use, the height of the water level, on the one hand, oppresses people through water pressure, causing breathing difficulties and other situations. On the other hand, stagnant water contains a large number of bacteria, causing infection to people and resulting in casualties. Some building materials will precipitate chemical substances when soaked in water for a long time, causing harm to the human body. According to the actual situation of the stagnant water, the danger of the stagnant water can be analyzed to obtain the degree of danger and determine the speed of flood discharge. For example, the stagnant water contains a large number of toxic substances, and people cannot soak for more than 30 minutes. At this time, the flood discharge speed needs to be fast enough to drain the water within 30 minutes. When the stagnant water is relatively clean, in order to reduce the harmful consequences caused by rapid flood discharge, the flood discharge speed can be reduced.

[0123] Reference Figure 7 , based on the personal danger degree data, calculating the economic losses caused by the water level, analyzing the flood danger degree according to the economic losses, and obtaining the danger data, specifically includes the following steps:

[0124] Step S41, based on the water level data, obtain the underground building materials submerged by the water level, calculate the loss of the building materials due to waterlogging, and obtain first loss data.

[0125] Step S42, according to the first loss data, obtain the objects in the building submerged by the water level, calculate the emergency loss caused according to the loss degree of the objects, and obtain the second loss data.

[0126] Step S43, based on the second loss data, obtain a positive correlation curve between the loss degree and the risk degree, match the corresponding risk degree according to the positive correlation curve between the loss degree and the risk degree, and obtain economic risk degree data.

[0127] Step S44, according to the personal danger level data and the economic danger level data, a weight ratio is set, and the overall flood danger level is comprehensively calculated to obtain danger data.

[0128] In actual application, flooding in underground buildings will not only cause personal danger, but also economic losses. Different economic losses can also analyze the degree of danger of flooding, thereby determining the speed of flood discharge. For example, in an underground garage, there are no people at night, and the water level is 10 cm, which only submerges the car tires and does not cause damage to the car. At this time, there is no need to start the flood discharge system because the noise of the flood discharge system will affect residents' sleep. However, when the water level reaches the car window, in order to reduce the water from the car window infiltrating into the car and causing damage to the car, it is necessary to drain water through the flood discharge system to reduce economic losses.

[0129] Reference Figure 8 The step of setting a weight ratio according to the personal danger degree data and the economic danger degree data, comprehensively calculating the overall danger degree of the flood, and obtaining the danger data also includes the following steps:

[0130] Step S441, based on the personal danger level data, obtain the minimum and maximum values ​​of the personal danger level, the minimum value of the personal danger level corresponds to a weight ratio of 0, and the maximum value of the personal danger level corresponds to a weight ratio of 100%, and generate a weight ratio curve.

[0131] Step S442, based on the weight ratio curve and the personal danger level data, match the weight ratio corresponding to the personal danger level, calculate the overall danger level according to the weight ratio, and obtain the personal danger data.

[0132] Step S443, based on the weight ratio curve, obtain the difference between the weight ratio of the personal danger degree and 100%, the difference between the weight ratio of the personal danger degree and 100% is the weight ratio of the economic danger degree data, and obtain the economic weight ratio data.

[0133] Step S444, based on the economic weight ratio data and the economic risk degree data, the overall risk degree caused by the economic risk is calculated using the weight ratio to obtain the economic risk data.

[0134] Step S445, combining the personal danger data and the economic danger data, superimposing the personal danger data and the economic danger data to obtain danger data.

[0135] In actual application, personal safety is more important than anything else. When personal danger is very serious, there is no need to consider economic danger. When there is no personal danger, only economic danger can be considered. For example, when the water level is only 5 cm, it will not cause harm to people. At this time, it is necessary to consider whether there is material loss at the 5 cm building and decide whether to start the flood discharge system. When the water level reaches one meter, the damage to people is very large. Personal safety should be the top priority and flood discharge should be carried out in time. When the water level is 20 cm, personal danger and economic danger can be considered comprehensively.

[0136] Reference Fig. 9 , based on the flood discharge time data, calculating the flood discharge speed, matching the corresponding flood discharge power, starting the flood discharge system to perform flood discharge work, and obtaining the flood discharge data, also includes the following steps:

[0137] Step S61, based on the flood discharge time data, set the safe water level value, calculate the discharge water volume to reach the safe water level according to the change of water level height at different times, and obtain the water volume data.

[0138] Step S62, based on the water volume data and the flood discharge time data, the flood discharge speed is calculated using the speed formula to obtain the flood discharge speed data.

[0139] Step S63, according to the flood discharge speed data, obtain a comparison table of flood discharge system power and flood discharge speed, match the corresponding equipment power according to the comparison table, and obtain the flood discharge power data.

[0140] Step S64, based on the flood discharge power data, start the flood discharge system to perform flood discharge work according to the corresponding flood discharge power to obtain flood discharge data.

[0141] In actual use, the flood discharge system has different flood discharge powers, representing different flood discharge speeds. The faster the flood discharge speed, the greater the impact of the accumulated water at the outlet, the greater the probability of causing harmful consequences, and the greater the noise. Setting different flood discharge speeds according to different situations is conducive to the rational use of the flood discharge system and is more energy-saving and environmentally friendly. For example, when the water level is only 1 cm, it can be drained through the drain without starting the flood discharge system, because the flood discharge system consumes a lot of electricity. When the water level is 20 cm, the human body can withstand it for 5 hours, so it can be drained through a slow flood discharge speed to reduce power consumption and be more energy-saving and environmentally friendly.

[0142] A waterproof flood discharge system for underground buildings, by applying the above-mentioned waterproof flood discharge method for underground buildings, includes a detection module, an analysis module, a calculation module and an execution module. The detection module is used to detect the water level height and flood-related parameters and output water level data. The analysis module is connected to the detection module by signal, and is used to receive water level data and output danger data after analyzing the danger degree. The calculation module is connected to the analysis module by signal, and is used to receive danger data and calculate the flood discharge speed and output speed data. The execution module is connected to the calculation module by signal, and is used to receive speed data and perform flood discharge work according to the preset speed.

[0143] In actual use, the control of the flood discharge system through electronic modules can reduce the waste of human resources on the one hand, and make the power control of the flood discharge system more accurate, energy-saving and environmentally friendly on the other hand. In addition, the flood discharge system will be closer to more scenarios, reducing the occurrence of high-power flood discharge for a small amount of accumulated water and low-power flood discharge for a large amount of accumulated water, making it more practical and convenient.

[0144] The implementation principle of this system is: first, the water level in different areas is detected by the detection module. If all underground buildings are accessible, the water level in all areas is consistent. Then the detection module detects the weather and predicts the precipitation. The analysis module calculates the change of water level over time based on the precipitation. Then the detection module detects the garbage content and building materials in the accumulated water. The analysis module analyzes the blockage of the drain outlet based on the garbage content, further confirms the water level, and the analysis module preliminarily analyzes the degree of danger of accumulated water to people and economic property through the water level. Then, according to the garbage content and building materials, the bacteria content and toxic substances in the accumulated water are analyzed, and the overall danger of accumulated water is analyzed by comprehensive weight ratio. The calculation module analyzes the flood discharge time according to the degree of danger, and analyzes the speed of flood discharge in combination with the water level. Finally, the execution module starts the flood discharge system to discharge flood according to the flood discharge speed.

[0145] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
