The embodiment of the present application is not limited to this.
The system provided by the embodiments of the present application will be further described below by way of alternative embodiments.
It should be noted that the rainfall, the river level in the river channel and the reservoir level that can be borne by the device in a certain area are all fixed. That is, when the rainfall in the area exceeds the set value of the rainfall in the area, or the river cannot satisfy the discharge of the rainfall rainwater, or the reservoir cannot accommodate the storage of the rainfall rainwater, a flood disaster may occur. Or when the rainfall in the area is less than the set value, or there is not enough rainwater stored in the river to satisfy the living and production water supply in the area, or there is not enough rainwater in the reservoir to satisfy the living and production water supply in the area, drought may occur. Therefore, the rainfall, the river level, the river flow rate and the reservoir level in the area need to be analyzed to obtain the real-time conditions of the rainfall, the river level, the river flow rate and the reservoir level in the area.
It should be noted that the rainfall setting value, the river level, the river flow rate setting value, and the reservoir level setting value provided in the embodiment of the present application may be determined according to different areas.
As an example, when the drainage and storage facilities in the area are relatively complete, or the drainage system in the area is relatively advanced, so that the excess rainwater can be drained or stored well, the rainfall setting value, the river level, the river flow rate setting value, and the reservoir level setting value can be relatively high, that is, the area can bear relatively large rainfall, and has a river channel with a relatively good circulation effect and a relatively large reservoir.
As another example, when the drainage and storage facilities in the area are not complete, or the drainage system in the area is not advanced and cannot drain or store the excess rainwater well, the rainfall setting value, the river level, the river flow rate setting value, and the reservoir level setting value may be low, that is, the area cannot bear a large rainfall, there is no channel with a good circulation effect, and there is no large reservoir.
When the river water level and the river water flow speed are larger than the set values of the river water level and the river water flow speed, the collection frequency of rainfall is improved; when the rainfall is larger than the rainfall set value, the acquisition frequency of the river water level and the river water flow speed is improved; and when the rising speed of the river water level is greater than the set value of the river water level, the acquisition frequency of the reservoir water level is increased. That is, when the rainfall is greater than the rainfall set value, or the river level and the river flow rate are greater than the river level and the river flow rate set value, or the reservoir level is greater than the reservoir level set value, the collection frequency of the rainfall, the river level and the river flow rate and the collection frequency of the reservoir level are increased to be the first frequency collection section.
When the river level and the river flow rate are higher than the set values of the river level and the river flow rate, it is indicated that the rainfall in the area is large, the river level rises, the river flow rate is high, and the set values of the river flow level and the river flow rate in the area are exceeded, so that the accommodation limit of the rainfall in the area is exceeded. It is therefore necessary to adjust the frequency of collecting rainfall. As an example, the frequency of collecting rainfall in the first time period is once in five minutes or once in ten minutes, and the frequency of collecting rainfall cannot meet the requirement of monitoring the river water level and the river water flow speed in the area, so that the frequency of collecting rainfall in the area needs to be increased. As an example, the increased rainfall collection frequency may be once every two minutes or once every one minute.
And when the rainfall is less than or equal to the rainfall set value and the river level, the river flow speed is less than or equal to the river level, the river flow speed set value and the reservoir level are less than or equal to the reservoir level set value, the collection frequency of the rainfall, the river level, the river flow speed and the reservoir level is a second frequency collection section.
And when the rainstorm warning time, the river warning time and the reservoir warning time are over, the rainfall collection frequency, the river water level, the river water flow speed collection frequency and the reservoir water level collection frequency are in a third frequency collection section.
The frequency of the first frequency acquisition section is greater than the frequency of the second frequency acquisition section.
As an example, the embodiment of the present application provides a schematic diagram to further illustrate the reciprocating cycle of the rainfall, the river level, the river flow rate and the reservoir level collection frequency in the first frequency collection segment, the second frequency collection segment and the third frequency collection segment. Referring to fig. 2, when the rainfall is greater than the rainfall setting value, or the river level, the river flow rate are greater than the river level, the river flow rate setting value, or the reservoir level is greater than the reservoir level setting value, it is indicated that the rainfall in the area exceeds the maximum bearing capacity that the area can bear, the river level, the river flow rate also exceed the accommodation range of the river channel in the area, and the water level of the reservoir also reaches the warning line of the reservoir in the area. That is to say, the rainfall, the river level, the river flow speed and the frequency of acquiring the reservoir level information are increased, and the natural disasters such as flood and the like caused by untimely information processing and receiving due to too long frequency of acquiring the information, namely too long time interval of acquisition are avoided.
And when the rainfall is less than or equal to the rainfall set value and the river level, the river flow rate is less than or equal to the river level, the river flow rate set value and the reservoir level are less than or equal to the reservoir level set value, the rainfall in the area is indicated to be within the bearing range of the waterproof facilities in the area, the river level and the river flow rate are also within the bearing range of the river channel in the area, and the water holding capacity of the reservoir is also within the bearing range, namely when the rainfall acquisition frequency, the river level, the river flow rate acquisition frequency and the reservoir level acquisition frequency can be set to a second frequency acquisition section. That is, the second frequency acquisition segment may be less frequent than the first frequency acquisition segment. Therefore, the monitoring, prevention and control of the rain condition are achieved, and the monitoring cost is reduced.
And when strong rainfall may occur after keeping the second frequency acquisition for a period of time, at this time, the acquisition frequency of the rainfall, the river level, the acquisition frequency of the river flow rate and the acquisition frequency of the reservoir level may be adjusted to the first frequency acquisition section according to the rainfall, the river level, the river flow rate and the reservoir level. Or after the third frequency acquisition segment is maintained for a period of time, the conditions such as heavy rainfall may occur, and the acquisition frequency of the rainfall, the river level, the river flow rate and the acquisition frequency of the reservoir level can be adjusted to the first frequency acquisition segment according to the rainfall, the river level, the river flow rate and the reservoir level. And after the first frequency acquisition section is kept for a period of time, the rainfall acquisition frequency, the river level, the river flow rate acquisition frequency and the reservoir level acquisition frequency can be adjusted to the second frequency acquisition section according to the rainfall, the river level, the river flow rate and the reservoir level. The embodiment of the present application is not limited to this for the specifically adjusted frequency acquisition segment.
And when the rainfall, the river water level, the river flow speed and the reservoir water level information acquired according to the adjusted acquisition frequency reflect the real situation of the current water rain situation, acquiring the rainfall, the river water level, the river flow speed and the reservoir water level information according to the adjusted acquisition frequency of the rainfall, the river water level, the river flow speed and the reservoir water level information to obtain the target rainfall, the target river water level, the river flow speed and the target reservoir water level information.
It should be noted that, by adjusting the collection frequency of the information, when the information collected by the adjusted collection frequency can accurately reflect the water and rain conditions in the drainage basin, the information collected by the collection frequency can be used to evaluate the water and rain conditions in the drainage basin, and then whether to send out an early warning or not is judged according to the water and rain condition information collected by the collection frequency.
And when the rainfall, the river level, the river flow speed and the reservoir level information acquisition frequency are adjusted, acquiring again according to the adjusted information acquisition frequency. The collected objects are rainfall, river level, river flow speed and reservoir level information in the same area.
And when the target rainfall is larger than the rainfall set value, a rainstorm warning is given out.
When the target rainfall is larger than the rainfall set value, a rainstorm warning needs to be sent out in time, so that people can prepare for responding in advance, and the influence on local production and life is avoided or reduced.
It should be noted that the rainstorm warning can be determined according to the specific situation of the rainstorm. As an example, a rainstorm blue warning signal may be issued when the amount of rainfall will reach more than 50 millimeters in 12 hours, or has reached more than 50 millimeters and rainfall may continue; when the influence of the heat zone cyclone is possible or already generated within 24 hours, the average wind power on the coast or the land reaches more than 6 grades, or the gust reaches more than 8 grades and a typhoon blue early warning signal can be continuously sent out; when the wind is influenced by thunderstorm and strong wind within 6 hours, the average wind power can reach more than 6 grades, or gust is more than 7 grades and accompanied by thunder; or the wind is influenced by thunderstorm strong wind, the average wind power reaches 6-7 grades, or 7-8 grades of gust wind is accompanied by thunder, and a blue early warning signal of the thunderstorm strong wind can be continuously sent out possibly; when the rainfall reaches more than 50 mm within 6 hours, or reaches more than 50 mm and the rainfall may continue, a yellow rainstorm early warning signal can be sent out; when the rainfall reaches more than 50 mm within 3 hours, or reaches more than 50 mm and the rainfall possibly continues, an orange rainstorm early warning signal can be sent out; when the rainfall reaches more than 100 mm within 3 hours, or reaches more than 100 mm and the rainfall may continue, a red rainstorm warning signal can be sent out. The color and the grade of the rainstorm warning are not limited in the embodiments of the present application.
And when the target river water level and the river flow speed are larger than the set values of the river water level and the river flow speed, a river warning is sent out.
When the target river water level and the river water flow speed are larger than the set values of the river water level and the river water flow speed, the fact that the river water level in the area far exceeds the range which can be accommodated by the river channel in the area is shown, the river water flow speed is large, the river water flow speed exceeds the set value of the river water flow speed in the area, and therefore the possibility of flood disasters exists. Therefore, a warning is required to be given to enable the operator to know that the river level in the area is higher than the warning line, and flood control or other measures are required.
And when the target reservoir water level is higher than the set reservoir water level value, a reservoir warning is sent out.
When the target reservoir water level is higher than the reservoir water level set value, the upper limit of the reservoir water capacity in the area is indicated, and therefore more rainwater cannot be accommodated. At this time, a reservoir warning needs to be sent out, so that the operating personnel can know that the water level of the reservoir exceeds a warning line, and water needs to be discharged or other equipment capable of storing water needs to be prepared, so that the flood caused by reservoir water leakage or reservoir damage is avoided.
In an optional implementation manner, the system provided in the embodiment of the present application further includes:
and when the reservoir water level is greater than the reservoir water level set value, starting the valve to discharge the flood.
It can be understood that when the water level of the reservoir is greater than the set water level value, the reservoir cannot contain more rainwater, and water needs to be discharged in time to ensure the safe operation of the reservoir.
It should be noted that the set value of the water level of the reservoir provided in the embodiment of the present application may be determined according to the size of the reservoir, and as an example, when the volume of the reservoir is larger, the set value of the water level of the reservoir may be larger; when the reservoir volume is small, the reservoir water level set value may be small. The embodiment of the application does not limit the set value of the reservoir water level.
In an optional implementation manner, the system provided in the embodiment of the present application further includes: and storing the target rainfall, the target river level, the river flow speed and the target reservoir level information.
Through saving above-mentioned information, the monitoring and prevention and control to the rainy condition of next time of convenience.
In an optional implementation manner, the system provided in the embodiment of the present application further includes: and collecting next-time water and rain condition monitoring information according to the prefabricated prediction model, the rainfall, the river water level, the river water flow speed and the reservoir water level.
It should be noted that the system provided by the embodiment of the present application can store the collected rainfall, river level, river flow rate and reservoir level information, and can predict the next time rainfall monitoring information according to the stored rainfall, river level, river flow rate and reservoir level information in cooperation with the prefabricated prediction model. Further, the system provided by the embodiment of the application can know the state and the trend of the current water and rain condition according to the collected rainfall, river water level, river water flow rate and reservoir water level information, and can predict the next water and rain condition according to the trend.
It should be noted that the prefabricated prediction model provided by the embodiment of the present application may draw a curve through the rainfall, the river level, the river flow speed and the reservoir level information collected in the past, and the probability of the rainstorm that may occur in a certain period of time may be displayed through the curve.
