The types of the rain gauge include various types, for example, a siphon type rain gauge, a dump box type rain gauge, a weighing type rain gauge, a double valve capacity gate type rain gauge, and the like. In order to make the rainfall measured by the rain gauge more accurate, the accuracy of the rainfall needs to be tested before the rain gauge is used.

The calibration process of the peristaltic pump is described in detail below.

Please refer to fig. 3, which is an application scenario of the method for calibrating a peristaltic pump according to the embodiment of the present application. The scenario includes a calibration apparatus 301, a peristaltic pump 102, a calibrated meter 302, and a water reservoir 104.

The peristaltic pump 102 and the reservoir 104 may be connected by a water delivery device, such as a water delivery conduit, such that the peristaltic pump 102 may draw water from the reservoir 104. The meter 302 and the reservoir 104 may be connected by a water delivery device, such as a water delivery valve, so that the meter 302 may discharge water into the reservoir 104.

In the embodiment of the present application, the calibration device 301, the peristaltic pump 102, the measurer 302, and the water reservoir 104 are respectively described as different devices.

As an embodiment, the calibration device 301 and the testing device 101 may be the same device. In the embodiment of the present application, the calibration device 301 and the test device 101 are taken as different devices as an example.

Referring to fig. 4, a schematic flow chart of a method for calibrating a peristaltic pump according to an embodiment of the present application is shown, the method specifically includes the following steps:

s401, controlling the peristaltic pump to sequentially operate according to each group of reference working parameters in at least one group of reference working parameters, and injecting water into the calibrated measurer to obtain reference water injection amount corresponding to each group of reference working parameters;

and S402, fitting a water injection model of the peristaltic pump according to the at least one group of reference working parameters and the reference water injection amount corresponding to the at least one group of reference working parameters.

The general idea of the method for calibrating a peristaltic pump provided in the embodiments of the present application is described below.

The calibration device 301 controls the peristaltic pump 102 to sequentially pump water from the reservoir 104 to the calibrated meter 302 with each of the at least one set of reference operating parameters. The measurer 302 measures the amount of water injected by the peristaltic pump and transmits the amount of water injected to the calibration device 301, and the calibration device 301 can obtain the reference amount of water injected corresponding to each set of reference operating parameters. The calibration device 301 fits a water injection model of the peristaltic pump according to the at least one set of reference operating parameters and the respective corresponding reference water injection quantities. The water injection quantity model is used for representing the corresponding relation between any working parameter and reference water injection quantity within a preset working parameter range.

After describing the general idea of calibrating a peristaltic pump provided in the embodiments of the present application, specific embodiments of the steps are illustrated below.

In step S401, the peristaltic pump is controlled to sequentially operate with each of the at least one set of reference operating parameters, water is injected into the calibrated measurer 302, and before the reference injection amount corresponding to each set of reference operating parameters is obtained, the calibration device 301 may receive at least one set of reference operating parameters.

The reference operating parameter may be a preset operating parameter of the peristaltic pump 102, or may be a randomly generated operating parameter of the peristaltic pump 102, or may be an operating parameter of the peristaltic pump 102 set by an operator in real time, and the like, which is not limited in particular.

For example, the calibration apparatus 301 may be connected to a terminal apparatus, such as a Personal Computer (PC). A tester can set at least one group of reference working parameters of the peristaltic pump 102 through the PC, the PC responds to the at least one group of reference working parameters set by the tester and sends the at least one group of working parameters to the calibration equipment 301, and the calibration equipment 301 receives the at least one group of reference working parameters sent by the PC to obtain the at least one group of reference working parameters.

As another example, a tester may set at least one set of reference operating parameters of the peristaltic pump 102 via the calibration apparatus 301, and the calibration apparatus 301 operates in response to the tester's setting to obtain the at least one set of reference operating parameters.

After the calibration device 301 obtains at least one set of reference operating parameters, the calibration device 301 executes S401 to control the peristaltic pump to sequentially operate with each set of reference operating parameters in the at least one set of reference operating parameters, and inject water into the calibrated measurer 302 to obtain reference water injection amounts corresponding to each set of reference operating parameters.

Calibration apparatus 301 controls the start-up of peristaltic pump 102 and operates with a set of reference operating parameters. The peristaltic pump 102 may draw water from the reservoir 104 and fill the meter 302. The measurer 302 measures the water injection amount and sends the water injection amount to the calibration device 301, and the calibration device 301 receives the water injection amount sent by the measurer 302 to obtain the reference water injection amount corresponding to the set of reference operating parameters of the peristaltic pump 102.

As an example, after the calibration device 301 receives the water injection amount sent by the measurer 302, the measurer 302 may be controlled to discharge water into the water reservoir 104. Thus, after the measurer 302 is discharged, the calibration device 301 can control the operation of the peristaltic pump 102 with the following set of reference operating parameters. After the calibration device 301 controls the peristaltic pump 102 to operate with each of the at least one set of reference operating parameters, a reference water injection amount corresponding to each set of reference operating parameters can be obtained. Therefore, water in the reservoir can be recycled, dependence on water sources in the environment is reduced, and flexibility of a calibration process is improved.

As an example, in order to improve the accuracy of calibrating the peristaltic pump 102, after the peristaltic pump 102 is started, the peristaltic pump 102 may be controlled to pump water so that the water delivery conduit between the peristaltic pump 102 and the measurer 302 and the water delivery conduit between the peristaltic pump 102 and the water reservoir 104 are filled with water, so that when the calibration device 301 controls the peristaltic pump 102 to stop working, the error between the water injection amount measured by the measurer 302 and the actual water pumping amount of the peristaltic pump 102 is small.

As an example, there are various ways for the measuring device 302 to measure the water injection amount, and the measuring device 302 measures the weight of water and takes the weight as the water injection amount; alternatively, the weight may be converted into the volume of water according to the density of water, and the volume may be set as the water injection amount, specifically, according to the actual usage scenario, which is not limited herein.

For example, the calibration device 301 controls the peristaltic pump 102 to start and start timing. The peristaltic pump 102 draws water from the reservoir 104 at a first speed and fills the meter 302 until the end of the first period of time is reached, at which time the peristaltic pump 102 stops filling. The measurer 302 reads the current water amount to obtain the water injection amount. The measurer 302 sends the water injection amount to the calibration device 301, and the calibration device 301 receives the water injection amount sent by the measurer 302 to obtain a reference water injection amount corresponding to the first rotation speed and the first time length. The calibration device 301 controls the measurer 302 to discharge water into the reservoir 104. After the measurer 302 finishes discharging water, the calibration device 301 controls the peristaltic pump 102 to pump water from the water reservoir 104 at the second rotation speed until the calibration device 301 obtains the reference water injection amount corresponding to all the rotation speeds and the reference working time.

After the calibration device 301 executes S401, the peristaltic pump is controlled to sequentially operate with each set of reference operating parameters in the at least one set of reference operating parameters, water is injected into the calibrated measurer 302, and after the reference water injection amount corresponding to each set of reference operating parameters is obtained, S402 may be executed, and the water injection amount model of the peristaltic pump 102 is fitted according to the at least one set of reference operating parameters and the reference water injection amounts corresponding to each set of reference operating parameters.

The water injection quantity model is used for representing the corresponding relation between any working parameter and the reference water injection quantity within a preset working parameter range. The preset working parameter range may be a range formed by the maximum value and the minimum value in each reference working parameter, or may be a range determined according to a rainmeter precision standard marked when the rainmeter leaves a factory, or may be a range set by a worker, and the like, and is not limited specifically.

If the calibration device 301 obtains a set of reference operating parameters and corresponding reference water injection amount, please refer to fig. 5, which is a schematic diagram of a water injection amount model, then the reference operating parameters and corresponding reference water injection amount can be mapped into the coordinate system to obtain a mapping coordinate point. The abscissa axis of the coordinate system represents the operating parameter and the ordinate axis represents the reference water injection rate. And determining the line segment formed by the mapping coordinate point and the origin of the coordinate system within a preset working parameter range as a water injection model.

If the calibration device 301 obtains a plurality of sets of reference operating parameters and corresponding reference water injection quantities, please refer to fig. 6, which is a schematic diagram of a water injection quantity model, each reference operating parameter and corresponding reference water injection quantity may be mapped to the coordinate system to obtain each mapping coordinate point. The abscissa axis of the coordinate system represents the operating parameter and the ordinate axis represents the reference water injection rate. And determining a line segment within a preset working parameter range according to each mapping coordinate point, so that the distance from each mapping coordinate point to the perpendicular line of the line segment is short, and determining the line segment as a water injection model.

After the calibration device 301 performs S402, the testing device 101 may use the calibrated peristaltic pump 102 to test the rain gauge after fitting the water injection model of the peristaltic pump 102 according to at least one set of reference operating parameters and the corresponding reference water injection quantities respectively.

The test equipment 101 executes S201, receiving at least one set of operating parameters of the peristaltic pump 102. The process of receiving at least one set of working parameters by the testing device 101 is the same as the process of receiving at least one set of reference working parameters by the calibration device 301, and is not described herein again.

After receiving at least one group of working parameters of the peristaltic pump 102, the testing device 101 executes S202, controls the peristaltic pump to sequentially operate according to each group of working parameters in the at least one group of working parameters, and injects water into the rain gauge to be tested to obtain the water injection amount corresponding to each group of working parameters.

The process of controlling the peristaltic pump 104 to sequentially inject water into the rain gauge 103 to be tested according to each of the at least one set of working parameters by the testing device 101 to obtain the water injection amount corresponding to each set of working parameters is the same as the process of controlling the peristaltic pump 104 to sequentially operate according to each of the at least one set of reference working parameters by the calibration device 301 to inject water into the calibrated measurer 302 to obtain the reference water injection amount corresponding to each set of reference working parameters, which is not described herein again.

For example, the operating parameters include the speed and length of time of operation of the peristaltic pump. The test apparatus 101 controls the peristaltic pump 104 to pump water from the reservoir 104 at a first rate of rotation and begins timing. The peristaltic pump 104 injects water into the rain gauge 103 to be tested, and the test device 101 controls the peristaltic pump 104 to stop injecting water until the end time of the first working period is reached. The rain gauge 103 to be tested sends an output value to the testing device 101, the testing device 101 receives the output value sent by the rain gauge 103 to be tested, the output value of the rain gauge 103 to be tested is obtained, the rain gauge 103 to be tested is controlled to discharge water into the reservoir 104, and if the rain gauge 103 to be tested is a tipping-bucket rain gauge, the tipping bucket of the tipping-bucket rain gauge is controlled to discharge the water into the reservoir 104. The testing device 101 may determine the water injection amount corresponding to the first rotation speed and the first operating time period according to the output value of the rain gauge 103 to be tested.

As an example, the manner of obtaining the water filling amount by the rain gauge to be tested 103 includes, in addition to the manner of obtaining the water filling amount by measuring the weight of water after the water filling by the peristaltic pump 104 is completed or calculating the volume of water, for example, if the output of the rain gauge to be tested 103 is in a pulse form, please refer to fig. 7, which is a schematic diagram of a principle of the rain gauge to be tested, and the rain gauge to be tested 103 includes a water containing unit, a resistor R and a control unit. One end of the resistor R is connected with a power supply Vcc, the other end of the resistor R is connected with the water containing unit and the control unit, and the water containing unit and the control unit are connected with each other. The control unit, the resistor R and the power supply Vcc form a control circuit, and the control circuit outputs a pulse signal when the water quantity injected by the water containing unit of the rain gauge 103 to be tested reaches the water injection quantity resolution. The rain gauge to be tested 103 may then output an output pulse to the testing device 101 each time the amount of water injected reaches the injection water rate resolution. When the peristaltic pump 102 stops filling, the testing device 101 determines the number of output pulses of the rain gauge 103 to be tested. Alternatively, the rain gauge 103 to be tested statistically outputs pulses whenever the amount of water injected reaches the water injection amount resolution. When the peristaltic pump 102 stops priming, the number of output pulses, etc. is sent to the test device 101.

After obtaining the number of output pulses of the rain gauge 103 to be tested, the testing device 101 calculates the water injection amount corresponding to the working parameters according to the product of the number of output pulses and the water injection amount resolution, and obtains the water injection amount corresponding to each group of working parameters. The water injection amount resolution represents the minimum value of the water injection amount that can be measured by the rain gauge 103 to be tested, and may be the mass of water, the volume of water, or the like, and is not limited specifically.

After the test equipment 101 executes S202, the peristaltic pump is controlled to sequentially operate according to each set of working parameters in at least one set of working parameters, water is injected into the rain gauge to be tested, and water injection amounts respectively corresponding to each set of working parameters are obtained, the test equipment 101 executes S203, and the accuracy of the rain gauge corresponding to each water injection amount is obtained according to at least one water injection amount and errors between reference water injection amounts respectively corresponding to the at least one water injection amount.

After the test equipment 101 calibrates the peristaltic pump 102 to obtain the water injection model of the peristaltic pump 102, the reference water injection corresponding to the operating parameter associated with the water injection can be determined according to the water injection model. For example, the first water injection amount obtained by the test apparatus 101 is a water injection amount associated with a first speed and a first operating period of the peristaltic pump 102, and then the test apparatus 101 determines a reference water injection amount associated with the first speed and the first operating period in the water injection amount model. The test apparatus 101 determines the accuracy of the rain gauge corresponding to the amount of water injection according to the error between the amount of water injection and the reference amount of water injection, and thus, the accuracy of the rain gauge corresponding to each amount of water injection can be obtained. Please refer to formula (1):

I＝|m_a-m_b| (1)

Alternatively, in order to reduce the influence of the magnitude of the water injection amount on the error, the error between the water injection amount and the reference water injection amount may be normalized to be suitable for determining the accuracy of the rain gauge corresponding to the water injection amount according to the water injection amount in different ranges, please refer to formula (2):

after the testing device 101 performs S203 to obtain the accuracy of the rain gauge corresponding to each water injection amount according to at least one water injection amount and the error between the reference water injection amounts respectively corresponding thereto, S204 may be performed to output the test result of the rain gauge to be tested based on the accuracy of the rain gauge corresponding to each water injection amount.

After obtaining the accuracy of the rain gauge corresponding to each water injection amount, the testing device 101 may determine at least one water injection amount of which the accuracy of the rain gauge is within a preset accuracy range. The method for determining at least one water injection amount by the testing device 101 may be directly determined by numerical comparison, or may map the accuracy of the rain gauges corresponding to each water injection amount into a coordinate system, please refer to fig. 8, which is a mapping diagram of the water injection amount and the accuracy of the rain gauges, and determine at least one water injection amount and the like within a preset accuracy range, and the specific determination manner is not limited.

After determining the at least one water injection amount within the preset accuracy range, the testing device 101 may further determine a maximum value of the at least one water injection amount, determine the water injection amount range of the rain gauge 103 to be tested by using the water injection amount with the largest value as the maximum value of the water injection amount range and using the water injection amount resolution as the minimum value of the water injection amount range.

For example, the preset accuracy range is [ -4%, 4% ], the water injection amount resolution is 0.01mm/min, and if the maximum value of at least one water injection amount is 150ml/min (4.7mm/min), the water injection amount range of the rain gauge 103 to be tested is [0.01, 4.7 ].

The test device 101 compares the water filling amount range of the rain gauge 103 to be tested with the reference water filling amount range in the rain gauge accuracy standard of the rain gauge 103 to be tested after obtaining the water filling amount range of the rain gauge 103 to be tested, for example, the error between the comparison of the water filling amount range and the reference water filling amount range by the test device 101 may be an error between the maximum value of the water filling amount range and the maximum value of the reference water filling amount range, or the like. And if the error between the water injection amount range and the reference water injection amount range is within a preset error range, outputting a test result for indicating that the rain gauge meets the rain gauge precision standard. And if the error between the water injection amount range and the reference water injection amount range is not within the preset error range, outputting a test result for indicating that the rain gauge does not meet the precision standard of the rain gauge.

The preset error range may be a range preset by a tester, or may be a range calculated by the testing device 101 according to historical data of a rain gauge of the same model or the same brand, and the like, and is not limited specifically.

As an example, the type of the rain gauge to be tested may be any, for example, a siphon rain gauge or a dump box rain gauge, and the rain gauge testing method may be used for testing, and has high flexibility.
