Description

Technical Field

[0001] This disclosure relates to the field of electrically controlled valve closing, and in particular to a method, apparatus, electronic device, and storage medium for testing the closing of a solenoid valve. Background Technology

[0002] With rapid economic development, the demand for solenoid valves in various industries is surging. Therefore, how to standardize valve closing conditions has become a key point to ensure the normal operation of electrical control systems.

[0003] In related technologies, since there are currently no specific valve-closing requirements in the field of electrically controlled valve closing, empirical values ​​are often used to design valve-closing circuits to control the closing of solenoid valves. However, these technologies lack systematic test data, the valve-closing conditions are unclear, and relying solely on empirical values ​​carries the risk of the solenoid valve failing to close. Furthermore, the inability to uniformly define valve-closing requirements for different scenarios makes it impossible to accurately determine the minimum valve-closing current. Excessive valve-closing current can lead to abnormal temperature rise, thereby affecting the reliability of the solenoid valve and resulting in low valve-closing success rate and efficiency. Summary of the Invention

[0063] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar different contents and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0064] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for display, data used for analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties.

[0065] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application environment according to an exemplary embodiment, such as... Figure 1 As shown, the application environment may include a first preset power supply 101, a second preset power supply 102, and a valve closing test circuit 103.

[0066] In an optional embodiment, the valve closing test circuit 103 may include a solenoid valve under test and a valve closing control circuit. Specifically, the solenoid valve under test may be a dual-coil solenoid valve, which may include a main coil and a secondary coil, and the valve closing control circuit may include an energy storage capacitor, a switching transistor, a resistor, a control chip, etc.

[0067] In an optional embodiment, the first preset power supply 101 can be used to provide a stable current to the main coil, and the second preset power supply 102 can be used to provide voltage to the secondary coil. Specifically, the first preset power supply and the second preset power supply can be voltage regulators.

[0068] Figure 2 This is a flowchart illustrating a solenoid valve closing test method according to an exemplary embodiment, such as... Figure 2 As shown, the solenoid valve closing test method is used in the valve closing test circuit and includes the following steps.

[0069] In step S201, power is supplied to the main coil of the solenoid valve under test based on the first preset power supply to open the solenoid valve under test.

[0070] In one specific embodiment, the first preset power supply can be a regulated power supply, the solenoid valve to be tested can be at least one solenoid valve, and the main coil can be a coil connected in series with the first preset power supply.

[0071] In step S203, the secondary coil of the solenoid valve under test is powered by the second preset power supply to perform a closing test on the solenoid valve under test. The resistance value of the resistor connected in series with the secondary coil is adjusted so that the current flowing through the secondary coil is located in each of the at least one target current interval. Multiple valve closing current values ​​corresponding to the secondary coil during multiple closing tests in any target current interval are recorded.

[0072] In one specific embodiment, the second preset power supply can be a regulated power source, and the secondary coil can be another coil other than the primary coil.

[0073] In one specific embodiment, the above-mentioned power supply to the secondary coil of the solenoid valve under test based on the second preset power supply for performing a closing test on the solenoid valve under test includes:

[0074] The second preset power supply is controlled to provide a first preset power supply signal to the auxiliary coil. The first preset power supply signal is a square wave voltage signal of preset duration. The voltage value corresponding to the square wave voltage signal is zero or a preset voltage value. The preset voltage value is greater than zero. The preset voltage value is consistent with the voltage provided by the first preset power supply to the main coil.

[0075] In a specific embodiment, the first preset power supply signal can be a square wave voltage signal of preset duration. The preset voltage value can be consistent with the voltage provided by the first preset power supply to the main coil. Specifically, the duration of the square wave voltage signal can be controlled based on the second preset power supply and the configured I / O port. For example, when the first preset power supply signal is a 200ms square wave voltage signal, the voltage provided by the first preset power supply to the main coil is 10mV, and the voltage value corresponding to the square wave voltage signal is zero or 10mV, the second preset voltage is set to 10mV to continuously supply power to the secondary coil. Two high-level signals (10mV) and low-level signals (0V) with a duration difference of 200ms are sent to the valve shut-off circuit through the configured I / O port. Then, through the characteristics of the transistor inside the valve shut-off circuit, the square wave voltage signal provided to the secondary coil is two 200ms square wave signals.

[0076] In one specific embodiment, the above-mentioned power supply to the secondary coil of the solenoid valve under test based on the second preset power supply for performing a closing test on the solenoid valve under test includes:

[0077] The capacitor in the solenoid valve under test is controlled to provide a second preset power supply signal to the secondary coil. The second preset power supply signal is the voltage signal generated by the discharge of the capacitor in the solenoid valve under test. The initial voltage value of the voltage signal generated by the capacitor discharge is consistent with the voltage provided by the main coil by the first preset power supply.

[0078] In a specific embodiment, the second preset power supply signal can be a voltage signal generated by the discharge of a capacitor in the solenoid valve under test. The initial voltage value of the voltage signal generated by the capacitor discharge is consistent with the voltage provided by the first preset power supply to the main coil. Specifically, when the voltage provided by the first preset power supply to the main coil is 10mV, and the second preset power supply is disconnected, a low-level signal is sent to the valve closing circuit through the configured I / O to control the discharge of the energy storage capacitor in the valve closing circuit, thereby providing the second preset power supply signal to the secondary coil. The initial voltage value of the voltage signal generated by the discharge of the energy storage capacitor is 10mV.

[0079] In the above embodiments, based on the second preset power supply, a first preset power supply signal and a second preset power supply signal are provided to the secondary coil of the solenoid valve under test. The solenoid valve under test is closed under normal power supply and power disconnection conditions, respectively. This takes into account the diversity of actual situations, increases the minimum valve closing current value, and reduces the risk that the solenoid valve cannot close.

[0080] In one specific embodiment, at least one target current range can be at least one current value range flowing through the secondary coil determined based on the valve-closing test data. Any target current range can be one of the at least one target current ranges. Specifically, the lower limit of any target current range can be the maximum second preset current value of the secondary coil corresponding to the first valve-closing test data, and the upper limit of any target current range is the minimum second preset current value of the secondary coil corresponding to the second valve-closing test data.

[0081] In a specific embodiment, the valve closing test data can characterize the valve closing success rate. The first valve closing test data can be the valve closing test data in the corresponding valve closing test data group that is less than a preset threshold, and the second valve closing test data can be the valve closing test data in the corresponding valve closing test data group that is greater than or equal to the preset threshold. The preset threshold can be the minimum value that the valve closing success rate is to be achieved by human intervention. For example, when the preset threshold is 80%, and the valve closing test data in the valve closing test data group is 0%, 0%, 10%, 85%, and 100%, the first valve closing test data is 0%, 0%, and 10%, and the second valve closing test data is 85% and 100%.

[0082] In an optional embodiment, the valve-closing test data is obtained using the following method: specifically, as follows... Figure 3 As shown, the following steps may be included:

[0083] In step S301, based on the first preset power supply and at least one first preset current value, the current value of the main coil in the solenoid valve under test is adjusted so that the solenoid valve under test is opened at least once when the current of the main coil is at least one first preset current value.

[0084] In one specific embodiment, at least one first preset current value can be a preset current value flowing through the main coil. Specifically, based on the first preset power supply, the resistor connected in series with the main coil can be adjusted to make the current of the main coil reach the corresponding preset current value. For example, if the first preset power supply is a 30mV regulated source, and at least one first preset current value is 178.57mA, 357.14mA, 535.71mA, 714.29mA, and 892.86mA, the current of the main coil can be adjusted to 178.57mA, 357.14mA, 535.71mA, 714.29mA, and 892.86mA respectively by adjusting the resistor connected in series with the main coil. At this time, the corresponding main coil voltages are 5mV, 10mV, 15mV, 20mV, and 25mV, simulating the environment of the solenoid valve under different electromotive forces.

[0085] In step S303, when the current flowing through the main coil is the first target current value, the current value of the secondary coil in the solenoid valve under test is adjusted based on the second preset power supply and multiple second preset current values, so that the solenoid valve under test is closed multiple times when the current of the secondary coil is multiple second preset current values.

[0086] In one specific embodiment, the first target current value can be any of the first preset current values ​​among at least one first preset current value.

[0087] In one specific embodiment, the multiple second preset current values ​​can be multiple preset current values ​​flowing through the secondary coil. For example, the multiple second preset current values ​​can be 100mA, 150mA, 200mA, 250mA and 300mA.

[0088] In step S305, the valve closing test data corresponding to the solenoid valve to be tested is obtained when the current of the main coil is the first target current value and the current of the secondary coil is the second target current value.

[0089] In one specific embodiment, the second target current value can be any one of a plurality of second preset current values.

[0090] In the above embodiments, based on a first preset power supply and at least one first preset current value, the resistor connected in series with the main coil is adjusted so that the main coil current is at least one first preset current value, and the solenoid valve under test is opened at least once. Furthermore, when the current flowing through the main coil is a first target current value, the current value of the secondary coil in the solenoid valve under test is adjusted based on a second preset power supply and multiple second preset current values, so that the solenoid valve under test is closed multiple times when the current in the secondary coil is multiple second preset current values. This yields valve-closing test data corresponding to the solenoid valve under test. The valve-closing test data characterizes the valve-closing success rate when the main coil current is the first target current value and the secondary coil current is the second target current value. Subsequently, at least one target current interval can be divided based on the valve-closing success rate, thereby refining the current within any target current interval to approximate the minimum valve-closing current, improving the accuracy of the minimum valve-closing current and the efficiency of the valve-closing test.

[0091] In a specific embodiment, any test current pair may include a first preset current value corresponding to at least one first preset current value for the main coil and a second preset current value corresponding to one of multiple second preset current values ​​for the secondary coil. Specifically, when at least one first preset current value is 178.57mA, 357.14mA, 535.71mA, 714.29mA, and 892.86mA, and multiple second preset current values ​​are 100mA, 150mA, 200mA, 250mA, and 300mA, there may be 25 current pairs such as (178.57mA, 100mA), (178.57mA, 150mA), (178.57mA, 200mA), (178.57mA, 250mA), (178.57mA, 100mA), and (178.57mA, 300mA).

[0092] In one specific embodiment, the solenoid valve under test can correspond to at least one valve-closing test data group. The at least one valve-closing test data group can include multiple valve-closing test data sets. Specifically, each valve-closing test data group corresponds to multiple test current pairs, and one valve-closing test data set within each valve-closing test data group corresponds to one of the multiple test current pairs. For example, when the first preset current value is 892.86mA, and multiple second preset current values ​​are 100mA, 150mA, 200mA, 250mA, and 300mA, the current pairs corresponding to the current valve-closing test data group are (892.86mA, 100mA), (892.86mA, 150mA), (892.86mA, 200mA), (892.86mA, 250mA), (892.86mA, 100mA), and (892.86mA, 300mA). There are a total of 5 pairs. The valve closing test data are 0%, 0%, 0%, 100%, and 100%. The above valve closing test data correspond to 5 current pairs, that is, the specific situations are (892.86mA, 100mA, 0%), (892.86mA, 150mA, 0%), (892.86mA, 200mA, 0%), (892.86mA, 250mA, 0%), (892.86mA, 100mA, 100%), and (892.86mA, 300mA, 100%).

[0093] In one specific embodiment, the multiple valve-closing current values ​​can be adjusted by changing the resistance value of the resistor connected in series with the secondary coil so that the current flowing through the secondary coil is located in each of the at least one target current intervals. The multiple current values ​​corresponding to the secondary coil are recorded during multiple closing tests corresponding to any target current interval, when the valve is successfully closed.

[0094] In step S205, the target valve-closing current value corresponding to the solenoid valve to be tested is determined based on the multiple valve-closing current values ​​corresponding to at least one target current range.

[0095] In an optional embodiment, such as Figure 4 As shown, determining the target valve-closing current value corresponding to the solenoid valve under test based on multiple valve-closing current values ​​corresponding to at least one target current range may include the following steps:

[0096] In step S401, the minimum valve-closing current value corresponding to each of the multiple valve-closing current values ​​corresponding to each of the at least one target current intervals is determined.

[0097] In one specific embodiment, the minimum valve-closing current value can be the minimum current value among multiple valve-closing current values ​​corresponding to the target current range. Specifically, when the target current range is (150mA, 200mA), the corresponding multiple valve-closing current values ​​are 171mA, 173mA, 174mA, 177mA and 178mA, respectively, and the minimum valve-closing current is 171mA.

[0098] In step S403, the target valve closing current value is determined based on the minimum valve closing current value.

[0099] In one specific embodiment, the target valve-closing current value can be a current value obtained based on the minimum valve-closing current, used to determine the valve-closing requirement, and can be determined in the following manner.

[0100] In an optional embodiment, such as Figure 5 As shown, when there are multiple target current ranges, determining the target valve-closing current value based on the minimum valve-closing current value may include:

[0101] In step S501, the maximum valve-closing current value is determined from the multiple minimum valve-closing current values ​​corresponding to multiple target current ranges;

[0102] In one specific embodiment, the maximum valve-closing current value can be the maximum current value among a plurality of minimum valve-closing current values.

[0103] In step S503, the target valve closing current value is determined based on the maximum valve closing current value.

[0104] In a specific embodiment, the target valve closing current value can be the maximum valve closing current value or the sum of the maximum valve closing current value and the preset current increment. Specifically, when the maximum valve closing current value is 180mA and the preset current increment is 15%, the target valve closing current value can be 180mA or 207mA, and the preset current increment can be preset to ensure the success rate of valve closing.

[0105] In an optional embodiment, determining the target valve-closing current value based on the minimum valve-closing current value includes:

[0106] Use the minimum valve-closing current value as the target valve-closing current value;

[0107] or,

[0108] The sum of the minimum valve-closing current value and the preset current increment is used as the target valve-closing current value.

[0109] In the above embodiments, for at least one target current range, the minimum current value among the multiple valve-closing current values ​​corresponding to each of the at least one target current range is determined as the at least one minimum valve-closing current value. Then, the maximum current value among the at least one minimum valve-closing current values ​​is determined as the maximum valve-closing current value. By directly using the maximum valve-closing current value as the target valve-closing current value or by using the sum of the maximum valve-closing current value and a preset current increment as the target valve-closing current value, and the preset current increment can be preset, the success rate of valve closure is guaranteed. For the case of one target current range, by directly using the minimum valve-closing current value as the target valve-closing current value or by using the sum of the minimum valve-closing current value and a preset current increment as the target valve-closing current value, the accuracy of the minimum valve-closing current is guaranteed, the upper limit of the valve-closing current is increased, thereby improving the reliability of the solenoid valve and ensuring the success rate and efficiency of valve closure.

[0110] As can be seen from the technical solutions provided in the embodiments of this specification above, this specification uses a second preset power supply to power the secondary coil in the solenoid valve under test to perform a closing test on the solenoid valve under test. By adjusting the resistance value of the resistor connected in series with the secondary coil, the current flowing through the secondary coil is located in each of the at least one target current intervals. This can approximate the minimum valve closing current, improve the accuracy of the valve closing test, and by recording multiple valve closing current values ​​corresponding to the secondary coil during multiple closing tests in any target current interval, and based on the multiple valve closing current values ​​corresponding to each of the at least one target current intervals, determine the target valve closing current value corresponding to the solenoid valve under test. This can increase the upper limit of the minimum valve closing current, achieve the effect of setting valve closing specifications, avoid excessive valve closing current, thereby improving the reliability of the solenoid valve, ensuring the success rate and efficiency of valve closing, and reducing the risk of valve failure.
