[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Figure 1 The diagram shown illustrates a scenario applicable to an embodiment of this application. Figure 1 As shown, the scenario applicable to this application embodiment is a rainfall measurement scenario. Specifically, this scenario includes a rainwater measuring device 2 equipped with a weighing module 20 and a rainwater collection tank 21, and a server 23 connected to the weighing module 20.

[0035] The weighing module 20 is used to weigh the rainwater collection bucket, and the server 23 is used to acquire the weight data measured by the weighing module for the first time period; extract the weight change information corresponding to the weight data; determine the time period corresponding to the rainfall event in the first time period based on the weight change information; and determine the rainfall amount corresponding to the first time period based on the weight data of the time period corresponding to the rainfall event. In other words, this scenario implements a rainfall measurement method. Multiple rainwater measuring devices can share a single server, which can receive data uploaded by different rainwater measuring devices, thus saving resources.

[0036] It should be noted that this application also applies to another scenario. Figure 2 The diagram shows another scenario applicable to the embodiments of this application. Specifically, this scenario includes a rainwater measuring device 2, which includes a rainwater collection tank 21, a weighing module 20, and a calculation module 22 connected to the weighing module 20. Furthermore, there is a communication connection between the weighing module 20 and the calculation module 22.

[0037] Specifically, the weighing module 20 is used to weigh the rainwater collection bucket, and the calculation module 22 is used to acquire the weight data measured by the weighing module for the first time period; extract the weight change information corresponding to the weight data; determine the time period corresponding to the rainfall event in the first time period based on the weight change information; and determine the rainfall amount corresponding to the first time period based on the weight data of the time period corresponding to the rainfall event. That is, this scenario implements a rainfall measurement method. Figure 1 Compared to the scenario shown, this scenario does not require data transmission with servers or other related devices. Therefore, this scenario can ensure the real-time performance of the rainfall measurement method.

[0038] Exemplary methods

[0039] Figure 3The diagram shown is a schematic flowchart of a rainfall measurement method provided in an exemplary embodiment of this application. Figure 3 As shown in the embodiment of this application, the rainfall measurement method is applied to a rainwater measurement device including a rainwater collection bucket and a weighing module. The rainwater collection bucket includes a siphon tube, and the weighing module is used to weigh the rainwater collection bucket, including the following steps.

[0040] Step 100: Obtain the weight data for the first time period measured by the weighing module.

[0041] For example, the weighing module mentioned in step 100 can be a load cell. The load cell is used to calculate the weight increase due to rainfall.

[0042] Specifically, the rainwater collection bucket is used to collect rainwater. The top of the rainwater collection bucket is a rain inlet, which prevents rainwater from falling onto the outside of the bucket over a certain area. As rainwater flows through the rain inlet into the rainwater collection bucket, the weight of the bucket increases accordingly. A weighing sensor is installed at the bottom of the rainwater collection bucket to measure the increase in weight due to rainfall.

[0043] Step 200: Extract the weight change information corresponding to the weight data.

[0044] For example, the weight change information mentioned in step 200 is used to represent the change in the weight data of the rainwater collection bucket measured by the weighing module within a finite time range. It should be understood that the weight change information can be a positive or negative change in value.

[0045] Step 300: Based on the weight change information, determine the time period corresponding to the rainfall event in the first time period.

[0046] For example, in a rainfall event, rainwater accumulates continuously, thus increasing in weight. Based on the weight change information, the time period that matches the rainfall characteristics can be identified, thus determining the time period corresponding to the rainfall event in the first time period.

[0047] Step 400: Determine the rainfall amount corresponding to the first time period based on the weight data of the time period corresponding to the rainfall event.

[0048] For example, the rainfall mentioned in step 400 can be understood as the depth of the water layer that accumulates on the water surface without evaporation, infiltration and loss. The rainfall can intuitively represent the amount of rainfall in a certain area.

[0049] Specifically, there are many events that affect the weight of the rainwater collection tank, mainly including rainfall, debris falling in, evaporation, and siphoning. Different events will cause the weight data of the rainwater collection tank to change with different characteristics. Therefore, the cause of the weight change can be identified based on the weight change information, thereby determining the rainfall amount in the first period.

[0050] The rainfall measurement method provided in this application acquires weight data from a first time period measured by a weighing module; extracts weight change information corresponding to the weight data; determines the time period corresponding to the rainfall event within the first time period based on the weight change information; and then achieves the purpose of statistical rainfall based on the weight data of the time period corresponding to the rainfall event. The principle is simple and reliable, effectively reducing the complexity and cost of installing rainfall measurement devices. Furthermore, the method in this application can reduce the impact of the outdoor environment on rainfall measurement, avoiding the problem of large rainfall errors caused by environmental factors such as wind, sand, and fallen leaves, thereby effectively improving the accuracy and effectiveness of the measurement. In addition, this application has the advantage of wide applicability.

[0051] In particular, applying the rainfall measurement method provided in this application to outdoor work scenarios, especially in the agricultural field, is crucial for crops, as rainfall measurement determines crop yield. The rainfall measurement method provided in this application, based on weight data and weight change information, can determine the rainfall in the first time period. Compared to traditional rainfall measurement methods, the measurement accuracy is significantly improved, providing a foundation for subsequent application of rainfall measurement in farmland analysis.

[0052] Figure 4 The diagram shown is a schematic representation of an exemplary embodiment of this application, illustrating the process of determining the time period corresponding to a rainfall event in a first time period based on weight change information. Figure 3 This application extends from the embodiments shown. Figure 4 The illustrated embodiment will be described in detail below. Figure 4 The illustrated embodiments and Figure 3 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0053] like Figure 4 As shown, in the rainfall measurement method provided in this application embodiment, the time period corresponding to the rainfall event in the first time period is determined based on the weight change information, including the following steps.

[0054] Step 401: Based on the weight change information, the first time period is divided into M sub-time periods, where M is a positive integer.

[0055] Step 402: Based on the weight change information corresponding to each of the M sub-time periods, determine the time period corresponding to the rainfall event in the M sub-time periods.

[0056] Specifically, by analyzing the weight change information corresponding to each of the M sub-periods, the rate or frequency of change of rainwater weight can be determined, thereby identifying the time period corresponding to the rainfall event in the M sub-periods.

[0057] The rainfall measurement method provided in this application divides the first time period into multiple sub-time periods. By analyzing the weight change information corresponding to each of the M sub-time periods, the time period corresponding to the rainfall event in the M sub-time periods is determined, providing a prerequisite for subsequent rainfall statistics. Moreover, dividing the first time period into multiple sub-time periods for analysis is more conducive to ensuring the accuracy of the measurement results.

[0058] Figure 5 The diagram shown is a schematic flowchart of an exemplary embodiment of this application, which determines the time period corresponding to a rainfall event among M sub-time periods based on the weight change information corresponding to each of the M sub-time periods. Figure 6 The diagram illustrates the change of weight data over time according to an exemplary embodiment of this application. Figure 4 This application extends from the embodiments shown. Figure 5 The illustrated embodiment will be described in detail below. Figure 5 The illustrated embodiments and Figure 4 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0059] like Figure 5 As shown, in the rainfall measurement method provided in this application embodiment, the time period corresponding to the rainfall event in the M sub-time periods is determined based on the weight change information corresponding to each of the M sub-time periods, including the following steps. It can be understood that the following steps need to be performed for each of the M sub-time periods.

[0060] Step 501: If the weight change information indicates that the weight data in the sub-period is continuously and uniformly increasing, then the sub-period is determined to be the period corresponding to the rainfall event.

[0061] like Figure 6 As shown, the vertical axis G represents the weight data measured by the weighing module, and the horizontal axis T represents time. 0-t1 corresponds to... Figure 6 Sub-time period 1. Within the duration 0-t1, the weight change information indicates that the weight data measured by the weighing module in sub-time period 1 increases continuously and uniformly. Specifically, by analyzing the weight data changes within the duration 0-t1, the computer can determine that this change corresponds to only one slope value, and that the slope value is positive. Simultaneously, it determines whether the 0-t1 duration corresponding to sub-time period 1 meets the preset rainfall time range. If it does, then sub-time period 1 can be determined as the time period corresponding to the rainfall event. The preset rainfall time can be set to 30 minutes, or other values ​​can be set according to actual conditions. Furthermore, Figure 6 Sub-periods 3, 5, 6, 8, 11, and 13 all correspond to the time periods of the rainfall event.

[0062] Figure 7 The diagram shown is a flowchart illustrating a rainfall measurement method provided in another exemplary embodiment of this application. Figure 7 As shown in the embodiments of this application, the rainfall measurement method further includes the following steps.

[0063] Step 701: If the weight change information indicates that the weight data in the sub-period jumps and increases, then the sub-period is determined to be the period corresponding to the event of the object falling in.

[0064] For example, when debris falls into the rainwater collection bin, such as twigs, fallen leaves, or animal feces, the bin's weight will increase instantly. Figure 6 As shown, t2 corresponds to sub-period 9. Within the duration of t2, the weight change information indicates that the weight measured by the weighing module in sub-period 9 increases instantaneously. Specifically, by analyzing the weight data changes within the duration of t2, the computer can determine that this change corresponds to only one positive slope value. Simultaneously, it determines whether the duration of t2 corresponding to sub-period 9 meets the preset time range for the object falling in. If it does, then sub-period 9 can be determined as the time period corresponding to the object falling in event. The object falling in time can be set to 2 seconds or other values.

[0065] Step 702: If the weight change information indicates that the weight data in the sub-period first jumps to increase and then jumps to decrease, then the sub-period is determined to be the period corresponding to the animal stay event.

[0066] For example, when animals such as birds perch on the rainwater collection bucket, the weight of the bucket will initially increase for a certain period before decreasing. That is... Figure 6 Sub-period 15 corresponds to the animal stay event. Within the duration t3-t4, the weight change information indicates that in sub-period 15, the weight measured by the weighing module first increases a certain amount of time and then instantly decreases. Specifically, by analyzing the weight data changes within the duration t3-t4, the computer can determine that the change corresponds to two slope values: the first is a positive slope, and the second is a negative slope. Simultaneously, it determines whether the duration t3-t4 corresponding to sub-period 15 meets the preset animal stay time range. If it does, then sub-period 15 can be determined as the time period corresponding to the animal stay event. The animal stay time can be set to 10 minutes or other values.

[0067] Step 703: If the weight change information indicates that the weight data in the sub-period continues to decrease uniformly, then the sub-period is determined to be the period corresponding to the evaporation event.

[0068] For example, during an evaporation event, the weighing weight of the rainwater collection bucket will slowly and continuously decrease. That is... Figure 6Sub-period 2 corresponds to the evaporation event. The weight change information indicates that the weight measured by the weighing module continuously and uniformly decreases during sub-period 2. Specifically, by analyzing the weight data changes within sub-period 2, the computer can determine that this change corresponds to a negative slope value. Simultaneously, it determines whether the duration of sub-period 2 meets the preset evaporation time range. If it does, then sub-period 2 can be determined as the period corresponding to the evaporation event. The evaporation time can be set to 15 minutes, or other values. In addition, Figure 6 Sub-time periods 4, 10, 12, and 14 all correspond to evaporation events.

[0069] Step 704: If the weight change information indicates that the weight data in the sub-period decreases rapidly, then the sub-period is determined to be the period corresponding to the siphon event.

[0070] For example, in the event of a siphon event, the weighing weight of the rainwater collection bucket will decrease rapidly. That is... Figure 6 Sub-period 7 corresponds to the siphon event. The weight change information indicates that the weight measured by the weighing module decreases rapidly during sub-period 7. Specifically, by analyzing the changes in weight data within sub-period 7, the computer can determine that this change corresponds to a negative slope value. Simultaneously, it determines whether the duration of sub-period 7 meets the preset siphon time range. If it does, then sub-period 7 can be determined as the period corresponding to the siphon event. The siphon time can be set to 2 minutes, or other values.

[0071] It should be understood that a single siphon can occur within the rainwater collection tank, or multiple siphons can occur. Of course, if the rainfall is short, no siphon may occur at all. When the number of siphons in the rainwater collection tank is 0, the rainfall can be calculated directly based on the weight data measured by the weighing module.

[0072] The rainfall measurement method provided in this application analyzes the weight change information corresponding to each of the M sub-time periods to identify the cause of the weight change based on the weight change information, thereby determining the event corresponding to each sub-time period and providing auxiliary reference for subsequent rainfall statistics, which is beneficial to improving the accuracy of rainfall measurement.

[0073] Figure 8 The diagram shown is a flowchart illustrating a rainfall measurement method provided in another exemplary embodiment of this application. Figure 7 This application extends from the embodiments shown. Figure 8 The illustrated embodiment will be described in detail below. Figure 8 The illustrated embodiments and Figure 7 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0074] like Figure 8As shown, the rainfall measurement method provided in this application embodiment includes the following steps.

[0075] Step 801: If it is determined based on the weight change information that the first time period includes the time period corresponding to the siphon event, and it is determined that the next time period corresponding to the siphon event is the time period corresponding to the rainfall event, then the determined rainfall amount is compensated.

[0076] Specifically, as rainfall continues, the water level in the rainwater collection tank gradually rises. A siphon pipe is installed on the side of the tank. When the water level in the siphon pipe reaches the siphon level, a siphon occurs, and the water level in the collection tank then rapidly drops to a certain value. For prolonged rainfall, if the rainwater reaches the siphon line of the collection tank while rainfall is still ongoing, the rainfall during the period from the start to the end of the siphon will not be measured. Because the siphon time is relatively short, if the weight measured by the weighing sensor immediately and continuously increases after one siphon ends, it can be determined that rain was still falling during the siphon process. This ignored rainfall can be compensated for when calculating the final rainfall.

[0077] Step 802: Determine the compensated rainfall amount as the new rainfall amount corresponding to the first time period.

[0078] The rainfall measurement method provided in this application, when determining that the first time period includes the time period corresponding to the siphon event, and determining that the next time period corresponding to the siphon event is the time period corresponding to the rainfall event, compensates for the determined rainfall and uses the compensated rainfall as the actual rainfall of the first time period. Compared with traditional rainfall measurement methods, the measurement accuracy is significantly improved, providing a prerequisite for subsequent application of rainfall data in meteorological, hydrological, or agricultural fields.

[0079] Figure 9 The diagram shown is a flowchart of a rainfall measurement method provided in another exemplary embodiment of this application. Figure 10 The diagram shown is a schematic representation of the change in weighing weight over time according to another exemplary embodiment of this application. Figure 8 This application extends from the embodiments shown. Figure 9 The illustrated embodiment will be described in detail below. Figure 9 The illustrated embodiments and Figure 8 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0080] like Figure 9 As shown, in the rainfall measurement method provided in this application embodiment, the compensation for the determined rainfall includes the following steps.

[0081] Step 901: Determine the rainfall compensation amount based on the weight change information of the period preceding the siphon event.

[0082] Specifically, the period preceding the siphon event is the period preceding the rainfall event. For example... Figure 10 As shown, the vertical axis G represents the weight data measured by the load cell, and the horizontal axis T represents time. The period before and after the siphon corresponds to a rainfall event. The rainfall compensation amount 16 represents the weight of rainwater not measured during the time from the start to the end of the siphon. The siphon time corresponding to the rainwater collection bucket is determined based on the time period corresponding to the siphon event. The rainfall compensation amount is determined based on the weight change information of the period preceding the time period corresponding to the siphon event (i.e., the slope of the weight change in the period preceding the time period corresponding to the siphon event) and the siphon time corresponding to the rainwater collection bucket.

[0083] Step 902: Compensate the determined rainfall amount based on the rainfall compensation amount.

[0084] For example, the rainfall amount can be added to the rainfall compensation amount to obtain the actual rainfall amount corresponding to the first time period.

[0085] The rainfall measurement method provided in this application can automatically drain water using the siphon principle and automatically compensate for rainfall during siphon drainage, which greatly improves the accuracy of automatic rainfall measurement.

[0086] Figure 11 The diagram shown is a flowchart illustrating a rainfall measurement method provided in another exemplary embodiment of this application. Figure 3 This application extends from the embodiments shown. Figure 11 The illustrated embodiment will be described in detail below. Figure 11 The illustrated embodiments and Figure 3 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0087] like Figure 11 As shown, the rainfall measurement method provided in this application embodiment also includes the following steps.

[0088] Step 1100: Predetermine the weight of the empty rainwater collection bucket.

[0089] Specifically, when no debris falls into the bucket, the weight measured by the sensor after each siphon should be the same and equal to the weight of the empty bucket. However, if debris falls in, since the siphon only removes water, the debris will remain.

[0090] Step 1101: If it is determined based on the weight change information that the first time period includes the time period corresponding to the debris falling event, and it is determined that there is a time period corresponding to the siphon event after the time period corresponding to the debris falling event, then determine the weight of the rain collection bucket after the completion of the first siphon event following the time period corresponding to the debris falling event.

[0091] Specifically, such as Figure 6 As shown, sub-period 9 is the event of debris falling in. After sub-period 9, if the rainfall in the rain collection bucket reaches the siphon line, a siphon event will occur. If the weight of the rain collection bucket after the completion of the first siphon event following sub-period 9 corresponding to the debris falling in is different from the weight of the empty rain collection bucket, it can be determined that impurities have been added to the rain collection bucket.

[0092] Step 1102: Based on the weight of the rain collection bucket after the first siphon event is completed and the weight of the empty rain collection bucket, determine the weight of impurities in the rain collection bucket.

[0093] Specifically, the difference between the weight of the rain collection bucket after the first siphon event is completed and the weight of the empty rain collection bucket is the weight of the debris inside the rain collection bucket. The weight of the debris can be subtracted when calculating the final rainfall.

[0094] Step 1103: Correct the determined rainfall amount based on the weight of impurities in the rain collection bucket, and determine the corrected rainfall amount as the new rainfall amount corresponding to the first time period.

[0095] The rainfall measurement method provided in this application embodiment can determine the weight of impurities in the rain collection bucket based on the weight of the rain collection bucket after the completion of the first siphon event and the weight of the empty rain collection bucket, thereby correcting the rainfall and reducing the influence of the outdoor environment on rainfall measurement. It avoids the problem of large rainfall errors caused by environmental factors such as wind, sand and fallen leaves, and thus effectively improves the accuracy and effectiveness of the measurement.

[0096] Figure 12 The diagram shown is a flowchart illustrating a rainfall measurement method provided in another exemplary embodiment of this application. Figure 11 This application extends from the embodiments shown. Figure 12 The illustrated embodiment will be described in detail below. Figure 12 The illustrated embodiments and Figure 11 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0097] like Figure 12 As shown, in the rainfall measurement method provided in this application embodiment, after determining the weight of impurities in the rain collection bucket based on the weight of the rain collection bucket after the completion of the first siphon event and the weight of the empty rain collection bucket, the following steps are also included.

[0098] Step 1201: Predetermine the weight threshold corresponding to the impurities in the rain collection bucket.

[0099] It should be understood that a weight threshold can be set according to the actual situation, and the weight threshold should be greater than the weight of the empty rainwater collection bucket.

[0100] Step 1202: If the weight of impurities in the rainwater collection bucket is greater than the weight threshold, then the rainwater measuring device is cleaned of impurities.

[0101] The rainfall measurement method provided in this application sets a weight threshold. If the calculated weight of impurities exceeds this threshold, the user can be notified via an application (APP) or other channels to maintain and clean the rain collection tank. If the rainfall measurement device is equipped with a self-cleaning function, this function can be automatically activated to clean impurities, thus achieving timely removal of impurities and avoiding errors in rainfall measurement due to impurities, significantly improving the measurement accuracy of the rainfall measurement device.

[0102] Figure 13 The diagram shown is a flowchart illustrating a rainfall measurement method provided in another exemplary embodiment of this application. Figure 3 This application extends from the embodiments shown. Figure 13 The illustrated embodiment will be described in detail below. Figure 13 The illustrated embodiments and Figure 3 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0103] like Figure 13 As shown, the rainfall measurement method provided in this application embodiment also includes the following steps.

[0104] Step 1301: If it is determined from the weight change information that the first time period includes the time period corresponding to the evaporation event, then the evaporation compensation amount is determined from the weight change information of the time period corresponding to the evaporation event.

[0105] Specifically, based on the weight change information corresponding to the time period of the evaporation event, the evaporation time and evaporation rate of the evaporation event can be determined. Based on the evaporation time and evaporation rate, the evaporation compensation amount can be determined.

[0106] Step 1302: Compensate the determined rainfall amount based on the evaporation compensation amount, and determine the compensated rainfall amount as the new rainfall amount corresponding to the first time period.

[0107] Specifically, the amount of rainfall can be compensated by adding the amount of evaporation compensation.

[0108] The rainfall measurement method provided in this application can reduce the impact of the outdoor environment on rainfall measurement, and compensate for the determined rainfall based on evaporation compensation, thereby effectively improving the accuracy and effectiveness of the measurement.

[0109] Exemplary device

[0110] The above text combined Figures 1 to 13 The method embodiments of this application are described in detail below, in conjunction with... Figures 14 to 15 The present application provides a detailed description of the apparatus embodiments. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail can be found in the foregoing method embodiments.

[0111] Figure 14 The diagram shown is a schematic representation of a rainfall measurement device provided in an exemplary embodiment of this application. Figure 14 As shown, the rainfall measurement device provided in this application embodiment includes a rain collection bucket 21 with a siphon tube 18; a weighing module 20 for weighing the rain collection bucket; and a calculation module connected to the weighing module 20 for executing the rainfall measurement method mentioned in the above embodiment.

[0112] Specifically, a rainwater collection bucket 21 of a certain area first collects rainwater. The top of the bucket has a rain-collecting opening, which prevents rainwater from falling onto the outside of the bucket, thus reducing errors in rainfall measurement. When rainwater passes through the rain-collecting opening and is collected in the bucket 21, the weight of the bucket increases. To measure rainfall, a weighing sensor is located at the bottom of the bucket 21, which measures the increase in weight. The weighing sensor is mounted on a base 19. Additionally, a siphon 18 is located on the side of the bucket 21. When the rainwater in the bucket continues to rise and reaches the siphon position, it quickly drains the water, causing the water level to drop rapidly to a certain value. The rainwater in the bucket then rises again with the collected rainwater. The weighing sensor transmits the measured weight data of the bucket to a calculation module connected to the weighing module. The calculation module executes the rainfall measurement method mentioned in the above embodiment.
