[0021] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0022] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.
[0023] In addition, in the present application, directional terms such as "up", "down", "left" and "right" may be defined including but not limited to the orientation relative to the schematic placement of the components in the drawings. It should be understood that these directional terms may be relative concepts, which are used for relative description and clarification, and may change accordingly according to the change in the orientation of the components in the drawings.
[0024] In this application, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, the term "coupling" can be a way of achieving electrical connection for signal transmission.
[0025] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of variation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).
[0026] The existing Chinese invention patent (CN117452528A) is a fully automatic rainfall calibrator: the device uses a dual peristaltic pump and dual standard bottle configuration, with a 1000 ml large-capacity water tank. The actual product has an operating voltage of 20V. If it needs to achieve the national requirement of 8 hours of continuous working time, the overall weight and volume of the device need to be increased.
[0027] There is also a Chinese invention patent (CN102928892B) for a fully automatic rain gauge calibrator. The current device does not have the intelligent function of monitoring the water level in the standard bottle, and can only fill water according to the preset time. The level of intelligence needs to be improved. If there is a sudden power outage and restart when the standard bottle is full of water, the user will have to face the long waiting cycle again, which affects the convenience and efficiency of the operation. Due to the interference of environmental factors, the water level in the standard bottle cannot be maintained constantly on the 0 scale line. This fluctuation may cause a certain degree of deviation in the final measurement data.
[0028] In order to solve the above problems, a rainfall calibration device is provided in this embodiment, which will be described in detail below.
[0029] Reference Figures 1 to 6 The rainfall calibration device includes a box body 10, a metering component 20, a control component and a display component, wherein the box body 10 has a accommodating cavity, the metering component 20 and the control component are installed in the accommodating cavity of the box body 10, the control component is electrically connected to the metering component 20 and the display component respectively, and the display component is electrically connected to the control component; the control component controls the water output and water inflow of the metering component 20 to detect the accuracy of the rainfall calibration device, and displays data through the display component at the same time, wherein the display component includes a display screen 41, and the user can control the control component through the display screen 41.
[0030] Specifically, the metering component 20 includes a standard bottle 21, which is installed in the accommodating chamber of the box body 10; the control component includes a three-way solenoid valve 33, a motor 32 and a liquid level sensor, both of which are installed in the accommodating chamber of the box body 10, and the motor 32 is respectively connected to the standard bottle 21 and the three-way solenoid valve 33, and the liquid level sensor is used to detect the liquid level in the standard bottle 21, and the opening and closing of the three-way solenoid valve 33 enables the standard bottle 21 to take in water, stop taking in water or discharge water, and the motor 32 is used to pump water or inject water into the standard bottle 21; in this embodiment, two liquid level sensors can be provided, namely a first liquid level sensor 34 and a second liquid level sensor 35, the first liquid level sensor 34 is used to detect whether the water level in the standard bottle 21 reaches a first position (for example, whether it is full or overflowing), and the second liquid level sensor 35 is used to detect whether the water level in the standard bottle 21 reaches a second position (for example, whether it reaches the lowest standard line).
[0031] When testing is required, the motor 32 rotates forward, and at the same time, the first water inlet 331 and the first water outlet 332 of the three-way solenoid valve 33 are opened to perform the water supply operation, so that the external water (including rainwater or pure water for testing) enters the standard bottle 21 through the first water inlet 331, the first water outlet 332 and the motor 32 of the three-way solenoid valve 33 in sequence. At this time, the liquid level in the standard bottle 21 gradually rises. When the first liquid level sensor 34 detects that the water level in the standard bottle 21 rises to the first position, the motor 32 stops pumping water, thereby stopping water supply to the standard bottle 21. The control component realizes precise control of the water level by detecting the liquid level in the standard bottle 21.
[0032] In order to achieve accurate measurement of rainfall intensity, the metering component also includes a water tank 22, and the control component also includes a peristaltic pump 31 and a peristaltic control board 310 for controlling the operation of the peristaltic pump 31. The peristaltic pump 31 and the water tank 22 are also installed in the accommodating cavity of the box body 10, and the peristaltic pump 31 is connected to the water tank 22, and the water tank 22 is connected to the standard bottle 21 through a three-way solenoid valve 33 and a motor 32.
[0033] Specifically, when the first liquid level sensor 34 detects that the water level in the standard bottle 21 rises to the first position, the motor 32 stops pumping water, thereby stopping filling the standard bottle 21 with water; then the motor 32 reverses, and at the same time, the first water inlet 331 of the three-way solenoid valve 33 is closed, and the second water outlet 333 is opened, so that the water in the standard bottle 21 enters the water storage tank 22 through the motor 32 and the second water outlet 333. At this time, the water level in the standard bottle 21 continues to drop. When it drops to the second position, the motor 32 stops working, and at the same time, the peristaltic pump 31 starts working under the instruction of the peristaltic control board 310, so that the water in the water storage tank 22 is drained into the external rain gauge; when the sensor in the rain gauge detects that the water level reaches the requirement or the measuring bucket in the rain gauge stops flipping (under normal circumstances, when the water storage tank 22 is drained, the measuring bucket continues to flip), a stop working instruction is fed back to the peristaltic pump 31, thereby instructing the peristaltic pump 31 to stop working.
[0034] In this way, a single standard bottle 21 can be used to calibrate a rain gauge or conduct a rainfall simulation experiment, and by precisely controlling the water inlet and outlet, rainfall conditions of different intensities can be simulated, providing accurate rainfall data for fields such as meteorological monitoring, agricultural irrigation, and urban drainage.
[0035] It is worth mentioning that the three-way solenoid valve 33 and the motor 32 are used to control the forward and reverse rotation of water to the standard bottle 21 and the water tank 22. At the same time, the first liquid level sensor 34 and the second liquid level sensor 35 are combined to accurately detect the water level to achieve accurate control of the water level in the standard bottle 21, so as to eliminate the influence of environmental factors on the change of the water level in the standard bottle 21. Compared with the aforementioned Chinese invention patent (CN117452528A) a fully automatic rainfall calibrator, only one standard bottle 21 and one water tank 22 are needed to achieve the same function, which greatly reduces the size of the equipment, and the voltage required by the motor 32 and the sensor is relatively low, and no special electrical configuration is required, which further reduces the size of the equipment. Compared with the aforementioned Chinese invention patent (CN102928892B) rain gauge automatic calibrator, the liquid level is detected by the first liquid level sensor 34 and the second liquid level sensor 35, and the water inlet and outlet are controlled by combining external instructions and internal timing and other methods, thereby avoiding problems such as sudden power failure and restart caused by a single control method, and effectively improving the intelligence level and measurement accuracy of the equipment; and, in order to facilitate carrying, a handle 13 can be provided on the top of the box; it should be noted that, when the motor 32 can realize forward and reverse pumping, only one motor 32 can be provided, and if the motor 32 cannot realize forward and reverse rotation, at least a forward motor and a reverse motor need to be provided.
[0036] In particular, in order to adapt to different test areas and test environments, the installation height of the standard bottle 21 in the vertical direction can be adjusted according to actual needs, such as moving it up or down. At this time, the second position detected by the corresponding second liquid level sensor 35 also needs to be adjusted. In order to facilitate the observation of the upward or downward adjustment height, identification scale lines can be set on the standard bottle 21. For example, three identification scale lines are set, representing the upper limit of the standard bottle 21, the standard height, and the lower limit of the standard bottle 21, respectively. Of course, they can also be not set.
[0037] In addition, to prevent water in the standard bottle 21 from splashing out, the rainfall calibration equipment also includes a splash-proof device 50, which is installed on the box body 10 and connected to the top of the standard bottle 21 to isolate water splashed out during operation to prevent a short circuit.
[0038] In another embodiment, the splash-proof device 50 includes a splash-proof shell, which is installed in the accommodating cavity of the box body 10, wherein the splash-proof shell includes an integrally formed splash-proof part 51 and a water collecting part, and the water collecting part is provided with a water collecting slope 52; the splash-proof part 51 is connected to the standard bottle 21, and the water collecting part is connected to the water storage tank 22; when the water level in the standard bottle 21 continues to rise, part of the water is sprayed from the standard bottle 21 to the splash-proof part 51, and is collected along the water collecting part. At this time, the first liquid level sensor 34 detects the splash-proof device 50. If water is detected in the splash-proof device 50, it means that the water level in the standard bottle 21 has reached the first position, and the injection of water into the standard bottle 21 is stopped at this time; otherwise, it means that the first position has not been reached, and it is necessary to continue to inject water into the standard bottle 21.
[0039] It should be noted that if Figure 4 As shown, to ensure the normal operation of the equipment, the bottom of the splash-proof device 50 is connected to the overflow port 101 set on the box body 10, so that the water splashed into the splash-proof device 50 can be discharged; at the same time, to ensure the normal air pressure in the water tank 22 and avoid the air pressure in the water tank 22 being too high so that the water in the standard bottle 21 cannot enter the water tank 22, the water tank 22 can be connected to the exhaust port 102 of the box body 10, so that the gas in the water tank 22 can be discharged through the exhaust port 102; the water tank 22 can be connected to the water outlet 104 of the box body 10 through the peristaltic pump 31, so that the water in the water tank 22 can enter the rain gauge through the water outlet 104; similarly, the motor 32 can be connected to the water inlet 103 of the box body 10, so that external water can enter the standard bottle 21.
[0040] Furthermore, the rainfall calibration equipment includes a leveling device 60, which is installed at the bottom of the box 10. The leveling device 60 includes multiple support columns and multiple support pads. The multiple support columns are installed at the bottom of the box 10, and the multiple support pads are movably installed on the side of the multiple support columns away from the box 10. It is worth mentioning that the area of the support pads is larger than the area of the support columns.
[0041] That is to say, the measurement accuracy of the rainfall calibration device has high requirements on the levelness of the ground. When the designated working ground is uneven, the leveling device 60 can ensure that the rainfall calibration device always remains horizontal during use, thereby ensuring the accuracy and reliability of the calibration result.
[0042] In particular, in order to ensure the normal operation of the equipment, a lower computer 37 is provided which can control the control components to perform rainfall monitoring operations and equipment testing operations. The lower computer 37 is equipped with a built-in Bluetooth module for signal connection with upper computers such as external mobile phones and control devices. The lower computer can perform more detailed classification processing of rainfall of different intensities under the premise of complying with national standards. At the same time, the lower computer also has a built-in pause function module, which can pause the function as needed, thereby enhancing its practicality and enabling it to more effectively meet the diverse needs of users. The Bluetooth module can transmit data to mobile phones and the cloud in real time. At this time, the user can connect the Bluetooth module signal through the mobile phone Bluetooth to conveniently control the rainfall calibrator. In addition, the upper computer represented by external devices such as external mobile phones can also set a code scanning function to transmit control instructions. Or the QR code information / barcode information on other devices such as rain gauges is directly sent to the lower computer, and further transmitted to the cloud by the lower computer or controlled according to the control instructions to the three-way solenoid valve, motor, etc. At this time, the user can conveniently generate a calibration certificate with one click in the cloud, thereby avoiding tedious manual input steps; wherein, the QR code information / barcode information is used to indicate the device information (such as specifications, models, etc.) of other devices such as rain gauges. In particular, in order to ensure safety, the QR code and barcode information can be set to an encrypted QR code or a QR code, barcode or key in a specific encoding format (such as a quantum communication key, etc.), which is not limited here; it should be noted that in order to ensure the normal operation of the lower computer 37 and the peristaltic control board 310, an isolation plate 36 can be set in the accommodating cavity to isolate the water vapor generated by the standard bottle 21 during the water supply or water discharge process.
[0043] Specifically, for rainfall monitoring operations, such as Figure 8 As shown, including: Step S1, the lower computer 37 obtains a work instruction, and instructs the three-way solenoid valve 33 and the motor 32 to perform a water supply operation according to the work instruction, so that external water enters the standard bottle 21; that is, the lower computer 37 controls the motor 32 to rotate forward, and the first water inlet 331 and the first water outlet 332 of the three-way solenoid valve 33 are opened, and the water level in the standard bottle 21 begins to rise; Step S2, collecting the first liquid level information of the standard bottle 21 through the first liquid level sensor 34, and instructing the three-way solenoid valve 33 and the motor 32 to stop the water supply operation when the liquid level information meets the first liquid level condition, and instructing the three-way solenoid valve 33 and the motor 32 to perform the first water discharge operation, so that the water in the standard bottle 21 enters the water storage tank 22; that is, when the first liquid level sensor 34 detects that there is water in the splash-proof device 50, the water supply is stopped and the first water discharge operation is performed at the same time; Step S3, collecting the second liquid level information of the standard bottle 21 through the second liquid level sensor 35, and instructing the three-way solenoid valve 33 and the motor 32 to stop performing the first water discharge operation when the second liquid level information meets the second liquid level condition, and instructing the peristaltic pump 31 to perform the second water discharge operation at a preset first speed, so that the water storage tank 22 discharges water under the action of the peristaltic pump 31; Step S4, performing a rainfall detection operation according to the second water output operation result by using a rain gauge or other equipment.
[0044] It should be noted that after the rainfall monitoring operation is performed, in order to ensure the accuracy of rainfall monitoring, it is also necessary to collect rainfall monitoring results (such as the measurement results of the rain gauge and the results displayed on the display screen 41) and status data of the control component and the metering component 20 (such as the transmission of data or the duration of the working state of the control component during this working process, the time interval for the first liquid level sensor 34 / the second liquid level sensor 35 to detect data, the working interval and working duration of the peristaltic pump 31, etc.), and construct corresponding monitoring result matrices and equipment status matrices according to the preset format of these data, and then calculate the correlation between the monitoring result matrix and the equipment status matrix, and then calculate the correlation between the monitoring result matrix and the historical monitoring result matrix, and the correlation between the equipment status matrix and the historical status matrix (or Swap the calculation order of the two correlations), when both correlations meet the requirements, the data is determined to be normal, otherwise it is judged to be abnormal; of course, the device can also be connected to the Internet, the rainfall monitoring results can be compared with the broadcast / forecast results of the meteorological unit, or the rainfall monitoring results can be arranged in chronological order, and then the rainfall monitoring results can be normalized to convert the rainfall monitoring results into pixel points, and then the time-space distribution of the rainfall monitoring results can be determined, and the distribution can be input into the neural network model as a rainfall distribution image, and the confidence value of the image can be calculated by the softmax function of the model. When the confidence value is within the preset range, it is determined that the corresponding rainfall monitoring result meets the requirements, otherwise it is judged to be abnormal; of course, there can be other judgment methods, which are not limited here.
[0045] For test operations, such as Figure 7 As shown, including: Step S5, obtaining a test instruction, and determining a mode to be tested according to the test instruction; the test mode includes (but is not limited to) a drainage mode, a test mode, a manual mode, an automatic mode, etc.; Step S6, performing a test operation according to the test mode, and determining whether to perform a test result judgment and a data preservation judgment, or to perform an adjustment result display according to the test result.
[0046] Specifically, among them, Figure 7 As shown, the test process is as follows: 1. In the drainage mode, the metering component 20 is controlled to drain water. During the process, operations such as pause, continue, end, and exit are performed respectively to observe whether the relevant operations can be performed smoothly, and then the relevant test results are displayed; 2. In the test mode, a watering process is executed, in which operations such as pause, continue, end, and exit are respectively executed (the operation instructions of the relevant operations can be generated by the aforementioned display screen 41 or the aforementioned host computer), and then the relevant test results are displayed, and the results displayed at this time also include the adjustment results of the left and right support pads and the support columns of the leveling device 60; wherein, the watering process refers to continuously injecting water into the standard bottle 21 until the first liquid level sensor 34 can detect that there is water in the splash-proof device 50, and then executing the first water outlet operation, the second water outlet operation, and the rainfall detection operation; 3. In manual mode, first manually set the rainfall intensity data, rainfall, and whether to retest this time, and then enter the watering process, in which operations such as pause, continue, end, and exit are performed respectively, and then the relevant test results are displayed, and the relevant data are judged whether they are qualified, and the relevant data are saved at the same time, and then the manual mode is repeated according to the needs; 4. For the automatic mode, first select the process of the rainfall intensity to be tested, among which, process 1 is to execute 3 tests with a rainfall intensity of 4mm / min and a rainfall of 30mm, and 3 tests with a rainfall intensity of 1mm / min and a rainfall of 10mm; process 2 is 3 tests with a rainfall intensity of 4mm / min and a rainfall of 10mm, and 3 tests with a rainfall intensity of 1mm / min and a rainfall of 30mm; then enter the watering process and the automatic mode process, in which operations such as pause, continue, end, and exit are performed respectively, and then the relevant test results are displayed, and it is determined whether the relevant data is qualified, and the relevant data is saved at the same time, and then the automatic mode is repeated as needed.
[0047] In the above process, the lower computer 37 controls the control component through the following water output logic: 1. If the sensor of the rain gauge detects that the peristaltic pump 31 discharges water within a preset time (i.e., detects a rainfall pulse signal), the water discharge state is maintained; 2. If the sensor of the rain gauge does not detect water discharge from the peristaltic pump 31 within the preset time, it means that the water discharge is finished and the detection process is finished; 3. If it is manual mode or automatic mode, it mainly depends on whether the second liquid level sensor 35 detects the water level and whether the number of executions of the first water supply operation reaches the preset number (for example, whether it has been executed 3 times). If it does not reach the preset number (for example, only 2 times), the water supply operation, the first water outlet operation, and the second water outlet operation are repeated; and so on.
[0048] It is easy to understand that by setting the automatic mode, the testing efficiency can be improved and the errors caused by manual input and manual testing can be reduced.
