[0003] In the prior art, rainfall is usually predicted based on meteorological data. However, there are often uncertainties in the rainfall process. For example, factors such as meteorological conditions, topography, and urban environment in the rainfall area will affect the rainfall. Therefore, when using meteorological data to predict rainfall, there is usually a defect of inaccurate results. At the same time, the existing real-time monitoring solutions for rainfall intensity are also difficult to monitor rainfall intensity accurately and in real time.

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein.

[0055] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0056] With the increasing scarcity of water resources, making full use of and recycling water resources is one of the ways to alleviate water shortage, among which rainwater is an important component of water resources.

[0057] In the prior art, rainfall is usually predicted based on meteorological data. However, there are often uncertainties in the rainfall process. For example, factors such as meteorological conditions, topography, and urban environment in the rainfall area will affect the rainfall. Therefore, when using meteorological data to predict rainfall, there is usually a defect of inaccurate results. At the same time, the existing real-time monitoring solutions for rainfall intensity are also difficult to monitor rainfall intensity accurately and in real time.

[0058] Therefore, how to accurately determine the rainfall intensity in real time is the problem to be solved at present.

[0059] In order to solve the above problems, the embodiments of the present application provide a rain intensity determination device and a rain intensity determination method. Figure 1 A schematic diagram of a rain intensity determination device provided in an embodiment of the present application Figure 1 .

[0060] like Figure 1 As shown, the rain intensity determination device includes: a collection unit 1, a liquid level sensor 3, and a flow limiting unit 2, wherein the flow limiting unit 2 includes a plurality of flow limiting holes and a baffle.

[0061] Among them, the aperture of each flow limiting hole is different, such as Figure 1 The aperture of the limiting hole 21 shown in the flow limiting hole 22 is less than the aperture of the limiting hole 23 is less than the aperture of the limiting hole 24 is less than the aperture of the limiting hole 25.

[0062] The collection unit 1, for example, can be a collection container such as a collection funnel, which is used to collect rainwater. The diameter of the water inlet of the collection unit 1 is larger than the diameter of the water outlet.

[0063] In a rainfall scenario, rainwater may drip into the collection unit through the water inlet of the collection unit 1 to be collected by the collection unit 1 . The rainwater collected by the collection unit 1 may also flow out through the small-diameter water outlet of the collection unit 1 .

[0064] The liquid level sensor 3 may be, for example, Figure 1 The float type liquid level sensor shown. Take the liquid level sensor 3 as a float type liquid level sensor as an example: the float of the float type liquid level sensor can be set in the guide rail of the inner wall of the collection unit 1, for example. When there is rainwater in the collection unit 1, the float can move up and down along the guide rail based on its own buoyancy. At this time, the liquid level sensor determines the liquid level height of the rainwater collected in the collection unit based on the height of the float.

[0065] The flow limiting unit 2 may, for example, abut against the water outlet of the collection unit 1 .

[0066] Among them, the current limiting unit 2 can be, for example, Figure 1 The throttling orifice plate shown may also be other structures, as long as it can abut against the water outlet of the collection unit (the contact part is sealed) and limit the water outlet rate of the collection unit through the multiple flow limiting holes or baffles included in the flow limiting unit 2.

[0067] When the flow limiting unit 2 is a throttle orifice plate, the multiple flow limiting holes are throttle holes with different apertures arranged on the throttle orifice plate, and the baffle is other areas of the throttle orifice plate except the throttle holes.

[0068] It can be understood that if the baffle area of ​​the current limiting unit 2 abuts against the water outlet of the collection unit, the rainwater collected by the collection unit cannot flow out through the water outlet, and the water outlet rate is 0 at this time;

[0069] If the area where the flow limiting hole of the flow limiting unit is located is in contact with the water outlet of the collection unit, the rainwater collected by the collection unit can only flow out through the corresponding flow limiting hole. At this time, the larger the aperture of the flow limiting hole, the greater the water outlet rate of the collection unit; the smaller the aperture of the flow limiting hole, the smaller the water outlet rate of the collection unit.

[0070] In this embodiment, the water output rate of the collection unit can be limited by replacing the flow limiting holes with different apertures. In a possible implementation, the specific implementation of replacing the flow limiting holes with different apertures is as follows:

[0071] The rain intensity determination device further includes: a storage rack, on which an adjustment unit is provided;

[0072] The storage rack is placed beside the collection unit, and the current limiting unit is pre-installed on the storage rack.

[0073] The regulating unit may be, for example, an electric clamp or a pneumatic clamp, which is used to fix the flow limiting unit and make the flow limiting unit abut against the water outlet of the flow limiting hole at a certain angle or direction.

[0074] When the flow limiting hole needs to be replaced, the angle or direction of the flow limiting unit is adjusted through the adjustment unit so that the corresponding flow limiting hole abuts against the water outlet.

[0075] The contour area of ​​the limiting hole can be marked with a color or a number for easy identification and positioning. Different limiting holes correspond to different colors or numbers.

[0076] It is understandable that if the amount of rainwater collected in the collection unit is large, so that the liquid level detected by the liquid level sensor is greater than the first preset height, it indicates that the rain intensity (i.e., rainfall rate) is greater than the water discharge rate. In this scenario, the rainwater collected by the collection unit may overflow from the water inlet of the collection unit. Therefore, in order to avoid the overflow of the rainwater collected by the collection unit from the water inlet of the collection unit, when the liquid level sensor detects that the liquid level is greater than the first preset height, a larger aperture flow limiting hole area can be used to abut against the water outlet of the collection unit, so that the collection unit discharges water at a larger water discharge rate than the normal water discharge rate;

[0077] If in a rainfall scenario, the liquid level sensor detects that the liquid level height is less than the second preset height, it indicates that the rain intensity (i.e., the rainfall rate) is less than the water discharge rate. In this scenario, it may happen that all the rainwater collected by the collection unit flows out from the water outlet of the collection unit, so that no rainwater is collected inside the collection unit, and the liquid level sensor cannot monitor the corresponding liquid level height. Therefore, in order to avoid the situation where all the rainwater collected by the collection unit flows out from the water outlet of the collection unit and the liquid level sensor cannot monitor the corresponding liquid level height, when the liquid level sensor detects that the liquid level height is less than the second preset height, a flow limiting hole area with a smaller aperture can be used to abut against the water outlet of the collection unit, so that the collection unit discharges water at a smaller water discharge rate than the normal water discharge rate, thereby ensuring that the liquid level sensor can monitor the current liquid level height.

[0078] The rain intensity determination method provided in the embodiment of the present application determines the change in liquid level height within a preset time period through a liquid level sensor, and determines the rain intensity parameters corresponding to the rainwater collected within the preset time period based on the change in liquid level height and the amount of water output; the method can realize real-time monitoring of rainfall intensity, and because of the use of a flow limiting hole with a specific aperture, the determined rain intensity parameters are more accurate.

[0079] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be implemented independently or in combination with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0080] Figure 2 A schematic diagram of a method for determining rain intensity provided in an embodiment of the present application Figure 1 The execution subject of this embodiment can be, for example, Figure 1 The rain intensity determination device shown in the embodiment. Figure 2 As shown, the method for determining the rainfall intensity provided in this embodiment includes:

[0081] S201. Determine a first liquid level height and a second liquid level height by using a liquid level sensor.

[0082] The first liquid level height is the liquid level height of rainwater contained in the collection unit at the first moment, and the second liquid level height is the liquid level height of rainwater contained in the collection unit at the second moment.

[0083] The first moment may be earlier than the second moment, or may be later than the second moment, and this application does not impose any limitation on this.

[0084] And the first moment or the second moment may be the current moment. In the case where the first moment or the second moment is the current moment, the liquid level sensor monitors the liquid level height of the collection unit in real time so as to obtain real-time data in the first time.

[0085] S202: Determine a first capacity and a second capacity according to the first liquid level height and the second liquid level height.

[0086] The first capacity is the capacity of the collection unit at the first moment, and the second capacity is the capacity of the collection unit at the second moment.

[0087] It is understandable that the shape of the collection unit is certain, and the volume of the internal storage space is also certain. Therefore, after determining the liquid level height, the corresponding rainwater capacity can be obtained based on the height.

[0088] The first capacity may be, for example, greater than or less than the second capacity, or may be the same as the second capacity, depending on the corresponding rainfall rate and water discharge rate.

[0089] S203: Determine a rainfall parameter corresponding to a target period based on the first capacity, the second capacity, and a first flow limiting hole corresponding to the collection unit.

[0090] The target period is the period between the first moment and the second moment, and the rain intensity parameter is used to indicate the magnitude of the rain intensity.

[0091] The first flow limiting hole is the flow limiting hole corresponding to the flow limiting hole area abutted by the water outlet of the collection unit during the target period. That is, during the target period, the water flowing out of the water outlet of the collection unit can only flow out through the first flow limiting hole.

[0092] It is understandable that there is a correlation between the flow limiting hole and the water outlet rate of the collection unit. The flow limiting holes of different apertures correspond to different water outlet rates. The larger the aperture of the flow limiting hole, the greater the water outlet rate of the collection unit; the smaller the aperture of the flow limiting hole, the smaller the water outlet rate of the collection unit.

[0093] In this step, for example, the total water output in the target time period can be calculated through the first flow limiting hole, and then the final water input can be determined by combining the total water output, the first capacity and the second capacity.

[0094] The rain intensity determination method provided in the embodiment of the present application determines a first liquid level height and a second liquid level height through a liquid level sensor, wherein the first liquid level height is the liquid level height of rainwater contained in the collection unit at the first moment, and the second liquid level height is the liquid level height of rainwater contained in the collection unit at the second moment; according to the first liquid level height and the second liquid level height, a first capacity of the collection unit at the first moment and a second capacity of the collection unit at the second moment are determined; and based on the first capacity, the second capacity, and the first flow limiting hole corresponding to the collection unit, the rain intensity parameters corresponding to the target time period are determined; the method can accurately determine the rain intensity of the target time period, and provide real-time and sufficient data for agricultural production management, thereby effectively reducing the disaster losses caused by rainfall and ensuring the safety of agricultural production.

[0095] Figure 3 A schematic diagram of a method for determining rain intensity provided in an embodiment of the present application Figure 2 This embodiment is in Figure 2 Based on the embodiment, a possible implementation method for determining the rain parameter corresponding to the target time period based on the first capacity, the second capacity, and the first flow limiting hole corresponding to the collection unit is described in detail. Figure 3 As shown, the method for determining the rain intensity shown in this embodiment includes:

[0096] S301, determining the water outlet rate corresponding to the first flow limiting hole.

[0097] The water outlet rate may be determined, for example, by looking up a table, or may be calculated based on the aperture of the first flow limiting hole.

[0098] It is understandable that there is a corresponding relationship between the water outflow rate and the aperture. Before determining the rain intensity, the water outflow rates corresponding to the flow limiting holes of different apertures can be determined first, and an aperture-water outflow rate relationship table is generated based on the correlation between the two.

[0099] Alternatively, the area of ​​the corresponding flow-limiting hole is calculated based on the hole diameter, and the area is used as the corresponding water outlet rate.

[0100] S302: Determine the water output in a target period according to the water output rate.

[0101] The water output V can be determined by the following formula: 出 :

[0102] V 出 =R×Δt

[0103] Where R is the water output rate and Δt is the target period.

[0104] In one possible implementation, if the water output rate of the target period changes, the sub-water output of each sub-period can be determined based on the sub-periods corresponding to different water output rates, and then the sum of the multiple sub-water outputs can be used as the water output of the target period.

[0105] S303: Determine the water intake in the target time period according to the first capacity, the second capacity and the water output.

[0106] Among them, the water intake V in the target period can be determined by the following formula: 采 :

[0107] V 采 =V 出 +V 1 -V 2

[0108] Among them, V 出 is the water output during the target period, V 1 is the capacity corresponding to the end time of the target period (if the end time is the first time, then V 1 is the first capacity, V 2 is the second capacity; if the end time is the second time, then V 1 is the second capacity, V 2 is the first capacity).

[0109] S304: taking the ratio of the water collection amount to the target time period as the rain intensity parameter.

[0110] Among them, the following formula can be used to determine the rainfall parameters:

[0111]

[0112] The method for determining the rain intensity provided in this embodiment determines the water output through the water output rate of the current flow limiting hole, determines the total water collection based on the water output and capacity changes, and then determines the rain intensity parameters based on the water collection. The method is simple and effective, and the determination result has a high accuracy rate, providing real-time and sufficient data for subsequent agricultural production management, thereby effectively reducing the disaster losses caused by rainfall and ensuring the safety of agricultural production.

[0113] In one possible implementation, since the collection unit of the rain determination device provided in the embodiment of the present application may have a rainfall rate and a water outlet rate at the same time, the rain confirmation device may have a situation where the rainwater collected by the collection unit overflows from the water inlet of the collection unit, or the rainwater collected by the collection unit all flows out from the water outlet of the collection unit, and the liquid level sensor is unable to monitor the corresponding liquid level height.

[0114] The above two situations are explained below.

[0115] This is to address the possible situation where rainwater collected by the collection unit overflows from the water inlet of the collection unit.

[0116] First, it is necessary to determine whether the liquid level in the collection unit has reached a first preset height.

[0117] Among them, the first preset height h 1 For example, it can be 0.8h, where h is the total height of the accommodating space of the collection unit.

[0118] If the liquid level reaches the first preset height, it means that the rain intensity (i.e., rainfall rate) is greater than the water discharge rate, and the water discharge rate of the collection unit cannot meet the normal water discharge demand. In this scenario, the rainwater collected by the collection unit may overflow from the water inlet of the collection unit.

[0119] Therefore, in order to prevent the rainwater collected by the collection unit from overflowing from the water inlet of the collection unit, a second flow limiting hole can be determined based on the apertures of multiple flow limiting holes, and the second flow limiting hole can be used to replace the current flow limiting hole for water discharge.

[0120] It is understandable that the aperture of the second flow limiting hole needs to be larger than the aperture of the current flow limiting hole, so as to ensure that the water outlet rate becomes larger, thereby preventing the rainwater collected by the collection unit from overflowing from the water inlet of the collection unit.

[0121] If the liquid level does not reach the first preset height, it indicates that the rainwater collected by the collection unit will not overflow from the water inlet of the collection unit. Therefore, there is no need to increase the water discharge rate.

[0122] At this time, it can be determined whether the liquid level has reached a second preset height to determine whether the water outlet rate needs to be reduced.

[0123] The first preset height is greater than the second preset height, and the second preset height h 2 For example, it can be 0.2h. If the liquid level height does not reach the second preset height, it means that the water collected in the current collection unit is less, or the collected water has flowed out through the water outlet. At this time, the rain intensity (i.e., rainfall rate) may be less than the water outlet rate. In this scenario, all the rainwater collected by the collection unit may flow out from the water outlet of the collection unit, so that there is no rainwater collected inside the collection unit, and the liquid level sensor cannot monitor the corresponding liquid level height.

[0124] Therefore, in order to avoid the situation where all the rainwater collected by the collection unit flows out from the water outlet of the collection unit and the liquid level sensor is unable to monitor the corresponding liquid level height, the third flow limiting hole can be determined based on the apertures of multiple flow limiting holes, and the third flow limiting hole can be used to replace the current flow limiting hole to discharge water.

[0125] It is understandable that the aperture of the third flow limiting hole needs to be smaller than the aperture of the current flow limiting hole, so as to ensure that the water outlet rate becomes smaller, thereby avoiding the situation where all the rainwater collected by the collection unit flows out from the outlet of the collection unit and the liquid level sensor cannot monitor the corresponding liquid level height.

[0126] If the liquid level reaches the second preset height, it indicates that the liquid level sensor is able to monitor the corresponding liquid level. Therefore, there is no need to reduce the water output rate to improve the water accumulation efficiency in the collection unit.

[0127] In a possible implementation, when it is determined that the liquid level of the rainwater contained in the collection unit reaches a third liquid level, the fourth flow limiting hole is used to replace the baffle.

[0128] Among them, when it just starts to rain, there is not much rainwater in the collection device. If a flow-limiting hole is used to discharge water at this time, it may cause the collection unit to not collect rainwater, and the liquid level sensor cannot monitor the corresponding liquid level height. Therefore, when the rain determination device is in the initial state, the baffle in the flow-limiting unit abuts against the water outlet of the collection unit. The purpose of doing this is to collect more rainwater faster when entering a rainfall scene, so as to realize real-time monitoring of the rain earlier.

[0129] The third liquid level height is less than the second liquid level height, and the second preset height h 3 For example, it may be 0.1h. The fourth flow limiting hole is the flow limiting hole with the smallest pore size among the multiple flow limiting holes.
