Description

Technical Field

[0001] The invention relates to the technical field of rainwater storage and regulation, and in particular to a real-time dispatching method for rainwater storage and regulation facilities based on real-time meteorological information. Background Art

[0002] In recent years, stormwater control and rainwater utilization have received more and more attention in the planning and design of municipal drainage facilities and architectural design. In order to achieve the purpose of rainwater utilization while completing stormwater control, natural lakes are often used in engineering construction, or rainwater storage pools, rainwater barrels and other rainwater storage facilities are artificially set up to retain a part of rainwater for later recycling; at the same time, the stored rainwater can reduce the pressure of municipal rainwater drainage and reduce the runoff peak. The real-time scheduling of existing rainwater storage facilities often relies on the experience analysis of engineering designers, and lacks scientific and reliable scheduling and operation methods;

[0003] In the prior art, for example, the authorization announcement number CN 110570126 B discloses "a real-time dispatching method for rainwater storage facilities based on real-time meteorological information", and specifically discloses: establishing a host computer software dispatching and control platform for rainwater storage facilities, obtaining meteorological warning data issued by relevant national departments in real time in the control center, and calling the corresponding plan based on this; or obtaining the upcoming rainfall forecast information in real time, using genetic algorithms to make real-time decisions and optimize, and realizing real-time dispatching and control of rainwater storage facilities based on real-time meteorological information; however, in the above-mentioned technology, the optimization objective function is set to the water level in the rainwater pipe network at the flood-prone point upstream or downstream of the storage pool, or the peak flow rate of the confluence outlet runoff of the regional rainwater trunk pipe. This control dispatching can only alleviate a certain flow rate, but lacks the function of pre-storing rainwater. Once the rainwater exceeds the load of the pipe network, even if there is optimized dispatching, the problem of excess water cannot be solved. Therefore, the present invention proposes a real-time dispatching method for rainwater storage facilities based on real-time meteorological information to solve the problems existing in the prior art. Summary of the invention

[0004] In view of the above problems, the present invention proposes a real-time scheduling method for rainwater storage facilities based on real-time meteorological information. The real-time scheduling method for rainwater storage facilities based on real-time meteorological information uses an auxiliary buffer zone as a temporary rainwater storage area, which solves the problem of excess water. The first step of regulation is to gradually divert water according to the time sequence of the waterlogging points, and the second step of regulation is to radiate temporary storage with the waterlogging points as the center, so that the regulation plan can maximize the advantages of the overall system.

[0005] To achieve the purpose of the present invention, the present invention is implemented by the following technical scheme: a real-time scheduling method for rainwater storage facilities based on real-time meteorological information, comprising the following steps:

[0006] Step 1: Obtain engineering drawing data of urban rainwater pipes and record the geographical coordinates of each area;

[0007] Step 2: Based on BIM 3D integration technology, construct a 3D image model of the urban rainwater pipes to obtain a pipe network visualization model;

[0008] Step 3: Collect local rainfall and rainfall log reports over the years, evaluate the carrying capacity of stormwater pipes, mark waterlogging points in the model, and the time sequence of multiple waterlogging points;

[0009] Step 4: Simulate the construction of a rainwater storage pond in the stratum at the waterlogging point in the model, and simulate the construction of an auxiliary buffer zone around the waterlogging point;

[0010] Step 5: Implement the above method in reality according to the actual coordinates, with the rainwater storage tank located in the ground below the pipe network and the auxiliary buffer zone located on the roofs of buildings around the waterlogging point;

[0011] Step 6: Connect the rainwater storage tank and auxiliary buffer zone to the rainwater pipe network, set up solenoid valves at the connection points, record the carrying capacity of the rainwater storage tank and auxiliary buffer zone, and input them into the model;

[0012] Step 7: Collect real-time meteorological information, extract the estimated rainfall in the forecast, input it into the model to evaluate the carrying capacity of the rainwater pipe network, and when the estimated carrying capacity is insufficient, simulate the opening of the rainwater storage tank;

[0013] Step 8: When the carrying capacity of the rainwater storage tank is still insufficient after opening, close the auxiliary buffer zone outward with the waterlogging point as the center, temporarily store the rainwater, calculate the number of closures, formulate a plan, and implement it.

[0014] A further improvement is that in step one, engineering drawing data of urban rainwater pipes are obtained from the municipal construction system, regional remote sensing image data, and engineering planning and design data, and the detailed geographical location coordinates of the pipe network in each area are recorded.

[0015] Further improvements are as follows: in the step 2, a building model is established through 3Dmax according to the engineering drawing data, and the proportion of the internal dimensions is the same as the proportion of the actual area. Then the model data is input into the Revit software, the parameters are stretched into three-dimensional form, and then based on the BIM three-dimensional integration technology, ContextCapture is used to construct a three-dimensional image model to obtain a dynamic pipe network model. According to the actual urban area division, the pipe network model is divided into multiple nodes of interest, and a highlight display function is provided for each node of interest to obtain a pipe network visualization model.

[0016] Further improvements are as follows: in the step three, local rainfall and rainfall log reports over the years are collected, the time periods with concentrated local rainfall are analyzed as key monitoring time, and the actual maximum carrying capacity of the rainwater pipe is evaluated based on the amount of rainwater caused by waterlogging in the log report. At the same time, based on the location of the waterlogging point in the log report and the time sequence of the occurrence of multiple waterlogging points, the waterlogging points are marked in the model, and the waterlogging points are sorted in time sequence as the key monitoring order.

[0017] Further improvement lies in: in the step four, in the stratum at the waterlogging point in the model, a rainwater storage pool is simulated and constructed, the stock of the rainwater storage pool is sorted from large to small according to the waterlogging points, and an auxiliary buffer zone is simulated and constructed 3-6 kilometers around the waterlogging point, and the number of auxiliary buffer zones is gradually reduced from 6 kilometers around to 3 kilometers around according to the sorting of the waterlogging points.

[0018] Further improvement lies in: in the step five, the above method is implemented in reality according to the actual coordinates, the rainwater storage tank is set in the stratum below the pipe network, the rainwater storage tank is set as a three-in-one tank, clear flow tanks are set on both sides of the storage tank, and the upper overflow port of the storage tank is connected to the clear flow tank, the clear flow tank is connected to the municipal sprinkler storage, a valve is constructed at the interface, the bottom of the storage tank is connected to the sewage pipe network, and a valve is constructed at the interface.

[0019] A further improvement is that in step five, the auxiliary buffer zone is set on the rooftops of buildings around the waterlogging point, the auxiliary buffer zone is constructed by relying on the open space on the rooftops of the buildings, and the diversion outlet of the auxiliary buffer zone is connected to the water pipeline for building greening.

[0020] Further improvement lies in: in the step six, the rainwater storage tank and the auxiliary buffer zone are connected to the rainwater pipe network, and a solenoid valve is set at the connection; the connection between the rainwater storage tank and the rainwater pipe network is closed daily, and the connection between the auxiliary buffer zone and the rainwater pipe network is opened daily; the rainwater storage tank and the auxiliary buffer zone are input into the model as adjustment units, and the carrying capacity is displayed; liquid level gauges are set in the rainwater storage tank and the auxiliary buffer zone; when the liquid level exceeds the standard, a signal is sent to the model, and this adjustment unit is highlighted in the model.

[0021] A further improvement is that in step seven, when the carrying capacity is assessed to be insufficient, the opening of the rainwater storage tank is simulated, and the rainwater storage tanks under the corresponding waterlogging points are opened one by one according to the time sequence of the waterlogging points to carry the excess rainwater.

[0022] A further improvement is that in step eight, when the carrying capacity is still insufficient after all rainwater storage tanks are opened, the excess rainwater will be evenly distributed to multiple waterlogged points. With the multiple waterlogged points as the center, the auxiliary buffer zone will be gradually closed outward to temporarily store the rainwater, share the excess rainwater, calculate the number of closures, and formulate a pre-dispatching plan.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention constructs a pipe network visualization model, a rainwater storage tank and an auxiliary buffer zone, evaluates waterlogging points according to local historical rainfall and rainfall log reports, and sorts them in time series as a targeted scheduling plan. In actual applications, real-time meteorological information and estimated rainfall are collected to evaluate the carrying capacity of the rainwater pipe network. When the estimated carrying capacity is insufficient, the rainwater storage tanks under the corresponding waterlogging points are opened one by one according to the time series of the waterlogging points. When the carrying capacity is still insufficient, the auxiliary buffer zones are gradually closed outward with multiple waterlogging points as the center to temporarily store rainwater, so as to formulate a pre-scheduling plan. In summary, the auxiliary buffer zone is used as a rainwater temporary storage area to solve the problem of excess water. The first step of regulation is to gradually divert water according to the time series of the waterlogging points, and the second step of regulation is to perform radiation temporary storage with the waterlogging points as the center, so that the regulation plan can maximize the advantages of the overall system.

[0025] 2. The present invention constructs rainwater storage pools with different storage capacities in the underground strata under the waterlogging points to adapt to the severity of waterlogging at different waterlogging points, constructs auxiliary buffer zones on the roofs of buildings around the waterlogging points as temporary storage points for excess rainwater, and constructs a radiation range that adapts to the amount of excess rainwater at different waterlogging points. Thus, the empty and idle space on the roofs is utilized, making the overall regulation of rainwater waterlogging more flexible.

[0026] 3. The present invention sets the rainwater storage tank as a three-in-one tank. The clean water overflowing from the upper end of the storage tank enters the clear flow tank and is connected to the municipal sprinkler storage for the convenience of clean water utilization. The precipitated sewage in the storage tank is connected to the sewage network for the convenience of flushing the sewage network.

[0041] according to Figure 1As shown, this embodiment proposes a real-time scheduling method for rainwater storage facilities based on real-time meteorological information, including the following steps:

[0042] Obtain engineering drawing data of urban rainwater pipes from municipal construction systems, regional remote sensing image data, and engineering planning and design data, and record the detailed geographical location coordinates of the pipe network in various areas;

[0043] According to the engineering drawing data, a building model is established through 3Dmax, and the proportion of the internal size is the same as that of the actual area. Then the model data is input into the Revit software, the parameters are stretched and three-dimensionalized, and then based on the BIM three-dimensional integration technology, ContextCapture is used to construct a three-dimensional image model to obtain a dynamic pipe network model. According to the actual urban area division, the pipe network model is divided into multiple nodes of interest, and a highlight display function is provided for each node of interest to obtain a pipe network visualization model; the present invention is based on the BIM three-dimensional integration technology to construct a three-dimensional image model of the urban rainwater pipe. In the model, it is convenient to dispatch the pipe network, rainwater storage tank, and auxiliary buffer zone, and formulate a diversion and temporary storage plan for rainwater for intuitive display.

[0044] Collect local rainfall and rainfall log reports over the years, analyze the time periods with concentrated local rainfall as key monitoring time, and evaluate the actual maximum carrying capacity of the rainwater pipe based on the amount of waterlogging in the log report. At the same time, based on the location of waterlogging points in the log report and the time sequence of multiple waterlogging points, mark the waterlogging points in the model and sort them according to the time sequence as the key monitoring order;

[0045] In the model, the stratum at the waterlogging point simulates the construction of a rainwater storage pool. The stock of the rainwater storage pool is ranked from large to small according to the waterlogging point. An auxiliary buffer zone is simulated to be constructed 3-6 kilometers around the waterlogging point. According to the ranking of the waterlogging point, multiple auxiliary buffer zones are constructed from 6 kilometers around to 3 kilometers around. The present invention constructs a rainwater storage pool in the stratum below the waterlogging point. The stock of the rainwater storage pool is ranked from large to small according to the time sequence of the waterlogging point, which is adapted to the severity of waterlogging at different waterlogging points. An auxiliary buffer zone is constructed 3-6 kilometers around the waterlogging point. The auxiliary buffer zone is located on the roof of the building around the waterlogging point, and the open space on the roof is used as a temporary storage point for excess rainwater. The construction of the auxiliary buffer zone is gradually reduced from multiple constructions within 6 kilometers around to multiple constructions within 3 kilometers around according to the time sequence of the waterlogging point, which is adapted to the excess rainwater at different waterlogging points, and some idle space is used, so that the regulation and storage of the overall rainwater waterlogging is more flexible.

[0046] The above method is implemented in reality according to the actual coordinates. The rainwater storage tank is set in the stratum below the pipe network. The rainwater storage tank is set as a trinity tank. Clear flow tanks are set on both sides of the storage tank, and the upper overflow port of the storage tank is connected to the clear flow tank. The clear flow tank is connected to the municipal sprinkler storage. A valve is constructed at the interface. The bottom of the storage tank is connected to the sewage pipe network. A valve is constructed at the interface. The auxiliary buffer zone is set on the roof of the building around the waterlogging point. The auxiliary buffer zone is constructed by relying on the open space on the roof of the building, and the diversion port of the auxiliary buffer zone is connected to the building greening water pipeline. The present invention sets the rainwater storage tank as a trinity tank, the upper overflow port of the storage tank is connected to the clear flow tank, the overflowed clear water is connected to the municipal sprinkler storage, which is convenient for the use of clear water, and the precipitated sewage in the storage tank is connected to the sewage pipe network, which is convenient for flushing the sewage pipe network. The diversion port of the auxiliary buffer zone is connected to the building greening water pipeline, which is convenient for greening water. In summary, it is convenient to recycle excess rainwater in various ways.

[0047] Connect the rainwater storage tank and the auxiliary buffer zone to the rainwater pipe network, and install solenoid valves at the connections. The connections between the rainwater storage tank and the rainwater pipe network are closed on a daily basis, and the rainwater storage tank is not used to store water on a daily basis to reduce internal pollution. The connections between the auxiliary buffer zone and the rainwater pipe network are opened on a daily basis, and the auxiliary buffer zone is not used to temporarily store rainwater on a daily basis to avoid rainwater corrosion on the roof of the building. The rainwater storage tank and the auxiliary buffer zone are input into the model as adjustment units, and the carrying capacity is displayed. Liquid level gauges are installed in the rainwater storage tank and the auxiliary buffer zone. When the liquid level exceeds the standard, a signal is sent to the model, and the adjustment unit is highlighted in the model; this is convenient for operators to know the internal rainwater amount of the rainwater storage tank and the auxiliary buffer zone in time, so as to adjust and control it in time to avoid excessive water level.

[0048] Collect real-time meteorological information, extract the estimated rainfall in the forecast, input it into the model to evaluate the carrying capacity of the rainwater pipe network, and when the estimated carrying capacity is insufficient, simulate the opening of the rainwater storage tank, sort the waterlogging points in time sequence, and open the rainwater storage tanks under the corresponding waterlogging points one by one to carry the excess rainfall;

[0049] When the carrying capacity is still insufficient after all rainwater storage pools are opened, the excess rainwater will be evenly distributed to multiple waterlogged points. With multiple waterlogged points as the center, the auxiliary buffer zones will be gradually closed outward to temporarily store the rainwater, share the excess rainwater, calculate the number of closures, and formulate a pre-dispatching plan for its implementation. When in use, real-time meteorological information and estimated rainfall are collected to evaluate the carrying capacity of the rainwater pipe network. When the carrying capacity is assessed to be insufficient, the rainwater storage tank is opened in simulation, and the rainwater storage tanks under the corresponding waterlogging points are opened one by one according to the time sequence of the waterlogging points to carry the excess rainwater according to actual needs. When the carrying capacity is still insufficient after all the rainwater storage tanks are opened, the excess rainwater is evenly distributed to multiple waterlogging points. With multiple waterlogging points as the center, the auxiliary buffer zones are gradually closed outward to temporarily store the rainwater and share the excess rainwater, so as to formulate a pre-dispatching plan. In summary, the flow of waterlogging points is regulated in a targeted manner according to the waterlogging time sequence, and the waterlogging points are used as radiation centers and the surrounding auxiliary buffer zones are used as rainwater temporary storage areas, which solves the problem of excess water. The first step of regulation is to gradually divert the waterlogging points according to the time sequence, and the second step of regulation is to radiate and temporarily store the waterlogging points as the center, so that the regulation plan can maximize the advantages of the overall system.

[0050] The present invention is based on BIM three-dimensional integration technology to construct a three-dimensional image model of urban rainwater pipes. According to the local rainfall and rainfall log reports over the years, the local precipitation is evaluated, the waterlogging points are obtained, and they are sorted in time sequence as a targeted scheduling plan. In the model, real-time meteorological information and estimated rainfall are collected to evaluate the carrying capacity of the rainwater pipe network. When the estimated carrying capacity is insufficient, the rainwater storage tank is opened in a simulated manner. According to the time sequence of the waterlogging points, the rainwater storage tanks under the corresponding waterlogging points are opened one by one to carry the excess rainfall according to actual needs. When all the rainwater storage tanks are opened, the carrying capacity is When the amount is still insufficient, the excess rainfall will be evenly distributed to multiple waterlogged points. With multiple waterlogged points as the center, the auxiliary buffer zones will be gradually closed outward to temporarily store the rainwater and share the excess rainfall. In this way, a pre-dispatching plan can be formulated. In summary, the flow of waterlogged points is regulated according to the waterlogging sequence, and the waterlogged points are used as radiation centers and the surrounding auxiliary buffer zones as rainwater temporary storage areas, thus solving the problem of excess water. The first step of regulation is to gradually divert the flow according to the waterlogging sequence of the waterlogged points, and the second step of regulation is to perform radiation temporary storage with the waterlogged points as the center, so that the regulation plan can maximize the advantages of the overall system. In addition, the present invention constructs a rainwater storage pool in the underground layer under the waterlogging point. The storage capacity of the rainwater storage pool is adjusted from large to small according to the time sequence of the waterlogging point, adapted to the severity of waterlogging at different waterlogging points, and constructs an auxiliary buffer zone 3-6 kilometers around the waterlogging point. The auxiliary buffer zone is arranged on the roof of the building around the waterlogging point, and the open space on the roof is used as a temporary storage point for excess rainwater. The construction of the auxiliary buffer zone is gradually reduced from constructing multiple areas within 6 kilometers to constructing multiple areas within 3 kilometers according to the time sequence of the waterlogging point, adapted to the excess rainwater at different waterlogging points, and some idle space is used, so that the regulation and storage of the overall rainwater waterlogging is more flexible.
