Description

Technical Field

[0001] The present disclosure relates to the field of automated testing technology, and in particular to a testing method and related devices for a solenoid valve driver. Background Art

[0002] Solenoid valves are often used to control electrical equipment in coal mines. Each solenoid valve usually requires a drive signal to control its opening or closing, and the solenoid valve driver is a device used to provide these control signals. The existing test method of the solenoid valve driver mainly relies on human-computer interaction. The operator manually operates the hydraulic support controller of the frame to control the hydraulic support controllers of the left and right adjacent frames to output control signals to the solenoid valve driver, driving the closing and opening of the solenoid valve group coil, thereby realizing the control of objects such as columns and jacks. The performance of the solenoid valve driver is judged by analyzing the control effect on objects such as columns and jacks. However, this test method has the following shortcomings: 1. To test a solenoid valve driver, at least 2 hydraulic support controllers, multiple groups (for example, 32 groups) of solenoid valves and several connectors are required, and the test system is complex. 2. The operator is required to be extremely skilled in operating the test system, complete the construction and wiring of the test system, and be able to skillfully use the hydraulic support controller to control the solenoid valve driver. 3. Since each solenoid valve needs to be tested, it takes up to 32 repeated operations to detect whether each group of solenoid valves can be driven and perform closing and opening actions. The operator needs to observe whether the solenoid valve is working, which may lead to fatigue and misjudgment. The degree of automated testing is low and the labor intensity of testers is high. 4. The test process is a qualitative test, which only relies on the tester to observe whether the solenoid valve group is working. There is no quantitative test data, which is difficult to store and query. Summary of the invention

[0037] The first embodiment of the present disclosure provides a method for testing a solenoid valve driver. Figure 1 and Figure 2 As shown, the test method includes:

[0038] S100: In response to a control instruction sent by a host computer, a channel to be tested of the solenoid valve driver is determined.

[0039] Each solenoid valve usually requires a drive signal to control its opening or closing, and the solenoid valve driver is a device used to provide these control signals. The number of functions of the solenoid driver reflects the driver's ability and flexibility in controlling the solenoid valve. Different application scenarios may require solenoid valve drivers with different function numbers to meet specific control requirements. The number of functions is a comprehensive indicator that reflects the driver's ability and flexibility in controlling the solenoid valve. The number of functions can specifically include the number of control channels, where the solenoid valve driver has a single-channel solenoid valve driver and a multi-channel solenoid valve driver. The single-channel solenoid valve driver means that each channel can independently control a solenoid valve. For example, an 8-function solenoid valve driver can control 8 solenoid valves at the same time. Multi-channel solenoid valves mean that each channel can control multiple solenoid valves. For example, for a dual-channel solenoid valve driver, an 8-function solenoid valve driver can control 16 solenoid valves at the same time. For different application scenarios, all the channels of the solenoid valve driver may not be fully used, that is, if the control system only needs to control a small number of solenoid valves, then it is not necessary to use all the channels on the solenoid valve driver. In the initial stage of the test, the number of test channels of the solenoid valve driver is determined by the host computer. During the test, only the channels to be tested can be detected and then stopped. Channels that are not put into use do not need to be tested, thus avoiding test errors caused by testing channels that are not put into use.

[0040] S200: When the solenoid valve driver performs a target action, the voltage signals and current signals of all the channels to be tested are acquired.

[0041] The target action here at least includes opening the channels to be tested in sequence, wherein when one of the channels to be tested is in an open state, the other channels to be tested are in a closed state.

[0042] S200 specifically includes:

[0043] S201: Acquire a first voltage value and a first current value of the first channel, where the first channel is in an open state.

[0044] Specifically, if the solenoid valve driver has 5 channels to be tested, one of the 5 channels to be tested is controlled to be opened, and the voltage signal and current signal of the opened channel are measured. Here, the opened channel is the first channel, the value of the voltage signal of the opened channel is the first voltage value, and the value of the current signal of the opened channel is the first current value.

[0045] S202: Acquire a second voltage value and a second current value of the second channel, where the second channel is a channel in a closed state.

[0046] Specifically, if the solenoid valve driver has 5 channels to be tested, one of the channels has been controlled to open in step S201, and the voltage signals and current signals of the other 4 unopened channels are measured in step S202. The unopened channel is the second channel, the value of the voltage signal of the unopened channel is the second voltage value, and the value of the current signal of the unopened channel is the second current value.

[0047] In step S2, the channels to be tested are opened in sequence and the first voltage value and the first current value of the opened channels, as well as the second voltage value and the second current value of the unopened channels are recorded, which provides a basis for subsequent determination of the test results. Specifically, take the example of a solenoid valve driver having 5 channels to be tested. After controlling one of the channels (for example, channel 1) to open, measure the voltage signal and current signal of channel 1, and measure the voltage signal and current signal of the channels (channels 2 to 5) that have not received control instructions and remain closed; continue to control channel 2 to open, measure the voltage signal and current signal of the opened channel 2, and measure the voltage signal and current signal of the unopened channel 1 and channels 3 to 5; further, according to the above-mentioned operating steps, after controlling channel 3 to open, measure the voltage signal and current signal of the opened channel 3, and measure the voltage signal and current signal of the unopened channel 1, channel 2, channel 4 and channel 5; if there are 5 channels to be tested, control all the channels to be tested to open in turn, and detect the corresponding voltage signal and current signal as well as the voltage signal and current signal of the unopened channel.

[0048] S300: Based on the voltage signal and the current signal, determine whether the solenoid valve driver passes the test.

[0049] Furthermore, the channel voltage of the solenoid valve driver has a direct impact on its performance, including the operating voltage range, voltage adaptability, driving capability, protection function, and signal output. Ensuring that the solenoid valve driver works at a suitable voltage is essential to maintaining its performance and extending its service life. The solenoid valve driver needs to work within a certain voltage range to ensure its performance. For example, the rated voltage of the solenoid valve driver is 12VDC, and it should work normally within the range of 90% to 110% of the rated voltage. This means that the solenoid valve driver needs to maintain stable performance within the voltage range of 10.8V to 13.2V. The voltage adaptability of the solenoid valve driver determines its reliability under different power supply conditions. The solenoid valve should work normally within the range of 90% to 110% of the rated voltage, which shows that the solenoid valve driver needs to be able to adapt to voltage fluctuations to ensure stability and reliability under different power supply conditions. The channel voltage of the solenoid valve driver directly affects its ability to drive the solenoid valve. The channel voltage of the solenoid valve driver also affects the stability and reliability of its signal output. For example: the driver has 8 solenoid pilot valve control ports, each port has two high and low level signal outputs, where the low level is ≤0.5V and the high level is ≥9V, which ensures the clarity and accuracy of the signal.

[0050] Furthermore, the channel current of the solenoid valve driver has a direct impact on its performance, including current control accuracy, constant current drive, power consumption and heat dissipation, protection function and response time and duty cycle. The current control accuracy of the solenoid valve driver is crucial to maintaining the precise position of the solenoid valve. Some solenoid valve drivers use constant current drive, such as the LDT-AQ1007P model, with a single-channel constant current source current range of 0 to 1.6A and an accuracy of less than or equal to 2%. This constant current drive method ensures that the solenoid valve can obtain a stable current under different working conditions, thereby ensuring its performance. In the holding mode, reducing the solenoid valve current can reduce power consumption and heat dissipation. The solenoid valve driver usually has an overheating protection function to prevent damage caused by excessive current. The response time and duty cycle of the solenoid valve driver are also related to the channel current. The TLV1805-Q1 can achieve a drive frequency and duty cycle of 1kHz, as well as a larger duty cycle range from 1% to 99%, which helps to achieve faster response time and more precise control. The accuracy of current feedback is crucial to adjusting the PWM signal to maintain the precise position of the solenoid valve. The INA253-Q1 device output is proportional to the change in current through the solenoid valve, which shows that current feedback is very important for controlling the performance of the solenoid valve. Therefore, the qualification of the solenoid valve driver is determined by detecting the channel voltage and channel current.

[0051] Among them, when a channel is opened, the voltage value of the channel should reach the normal working voltage value, and the current value of the channel should reach the normal working current value. The voltage value of other unopened channels is very small (almost 0), and the current value of other unopened channels is very small (almost 0). Therefore, the solenoid valve driver can be tested by detecting the current value and voltage value of each channel.

[0052] Specifically include:

[0053] It is determined in sequence whether the first voltage value and the first current value meet the first predetermined condition, and whether the second voltage value and the second current value meet the second predetermined condition. Among them, the first voltage preset threshold is the voltage value at which the first channel of the solenoid valve driver can work normally, and the first current preset threshold is the current value at which the first channel of the solenoid valve driver can work normally. The first predetermined condition means that the first voltage value is greater than the first voltage preset threshold and the first current value is greater than the first current preset threshold. The second voltage preset threshold is the voltage value of the second channel when the first channel is open (generally almost 0), and the second current preset threshold is the current value of the second channel when the first channel is open (generally almost 0). The second predetermined condition means that the second voltage value is greater than the second voltage preset threshold and the second current value is greater than the second current preset threshold, wherein the first voltage preset threshold is greater than the second voltage preset threshold, and the first current preset threshold is greater than the second current preset threshold.

[0054] Specifically, if the first voltage value and the first current value meet the first predetermined condition, it is determined that the first channel has passed the test. That is, if the first voltage value is greater than the first voltage preset threshold and the first current value is greater than the first current preset threshold, it means that the voltage value and current value of the opened channel meet the requirements for normal operation, and it is determined that the first channel has passed the test. If the first voltage value and the first current value do not meet the first predetermined condition, it is determined that the first channel has not passed the test. That is, if the first voltage value is less than or equal to the first voltage preset threshold, or the first current value is less than or equal to the first current preset threshold, it means that the voltage value and current value of the opened channel do not meet the requirements for normal operation, and it is determined that the first channel has not passed the test.

[0055] Further, if the second voltage value is less than or equal to the second voltage preset threshold and the second current value is less than or equal to the second current preset threshold, it means that the voltage value and current value of the closed channel are very small (almost 0), which is consistent with the state of the closed channel. At this time, it cannot be determined whether the closed channel has passed the test, and subsequent tests need to be continued to find out. If the second voltage value and the second current value meet the second predetermined condition, it is determined that the second channel has not passed the test. That is, if the second voltage value is greater than the second voltage preset threshold and the second current value is greater than the second current preset threshold, it means that the voltage value and current value of the closed channel are too large, and it may be in an abnormal open state, and it is determined that the second channel has not passed the test.

[0056] In this embodiment, all channels to be tested are opened in sequence, and the voltage and current data in the open state and the voltage and current data of the corresponding unopened channels are measured. Each channel is subjected to multiple rounds of testing, and it is repeatedly confirmed in the sequential operation which channels have passed the test and which channels have not passed the test, so as to facilitate analysis and determine the location of the faulty channel.

[0057] If it is determined that a channel to be tested or a solenoid valve driver fails the test, a warning message is issued, for example, the information that the test fails is sent to a buzzer, and the buzzer gives an alarm prompt in the form of sound or light.

[0058] If all the channels to be tested pass the test, it is determined that the solenoid valve driver passes the test. If any channel to be tested fails, it is determined that the solenoid valve driver fails the test.

[0059] S400: Upload the voltage signal data and the current signal data to a database and generate a test result list.

[0060] In addition to uploading the voltage signal data and current signal data during the test to the database, it also includes uploading the standby voltage and standby current of the solenoid valve driver to the database, integrating the voltage signal data, current signal data, standby voltage and standby current, and generating a test result list, which is convenient for saving the test results for future reference.

[0061] Here, the solenoid valve driver has channels 1, 2, etc. as an example for explanation. When channel 1 is turned on, if the first voltage value is greater than the first voltage preset threshold value and the first current value is greater than the first current preset threshold value, it means that channel 1 has passed the test. If the first voltage value is less than or equal to the first voltage preset threshold value and the first current value is less than or equal to the first current preset threshold value, it means that channel 1 has failed the test.

[0062] Based on the same inventive concept as the first embodiment, the second embodiment of the present disclosure provides a testing device for a solenoid valve driver, comprising:

[0063] A determination module, used for determining a channel to be tested of the solenoid valve driver in response to a control instruction sent by a host computer;

[0064] An acquisition module, used for acquiring voltage signals and current signals of all the channels to be tested when the solenoid valve driver performs a target action;

[0065] A judgment module is used to judge whether the solenoid valve driver passes the test based on the voltage signal and the current signal.

[0066] Furthermore, the acquisition module includes:

[0067] A first acquisition unit, used for acquiring a first voltage value and a first current value of a first channel when controlling the solenoid valve driver to perform a target action, wherein the first channel is a channel in an open state;

[0068] The second acquisition unit is used to acquire a second voltage value and a second current value of a second channel, where the second channel is a channel in a closed state.

[0069] Furthermore, the judging module includes:

[0070] A first judging unit, configured to judge that the first channel passes the test when the first voltage value and the first current value meet a first predetermined condition;

[0071] a second judging unit, configured to judge that the second channel fails the test when the second voltage value and the second current value meet a second predetermined condition;

[0072] Furthermore, the device also includes:

[0073] a third judging unit, configured to judge that the first channel passes the test when the first voltage value is greater than a first voltage preset threshold value and the first current value is greater than a first current preset threshold value;

[0074] A fourth judgment unit is used to judge that the second channel has failed the test when the second voltage value is greater than a second voltage preset threshold and the second current value is greater than a second current preset threshold, wherein the first voltage preset threshold is greater than the second voltage preset threshold, and the first current preset threshold is greater than the second current preset threshold.

[0075] Furthermore, the device also includes:

[0076] The test result determination module is used to determine that the solenoid valve driver passes the test when all channels to be tested pass the test.

[0077] Furthermore, the device also includes:

[0078] The warning module is used to issue a warning message when it is determined that the solenoid valve driver fails the test.

[0079] Furthermore, the device also includes:

[0080] The result generation module is used to upload the voltage signal data and the current signal data to a database and generate a test result list.

[0081] Among them, the test device also includes a solenoid valve module, where the solenoid valve driver is electrically connected to the solenoid valve module, and the solenoid valve module is used to simulate a real solenoid valve, serving as a load for the solenoid valve driver to form a loop, thereby providing the test device with the possibility to detect the current value of the channel to be tested.

[0082] Specifically, a dual-channel solenoid valve driver (with a function number of 5) is used as an example for description, wherein the first preset voltage threshold of the solenoid valve driver is 10 V, and the first preset current threshold is 100 mA.

[0083] First, the host computer issues a control instruction, and the determination module analyzes that the channel to be tested of the solenoid valve driver is 5 based on the function number of the solenoid valve driver being 5;

[0084] Next, control channel 1 of the solenoid valve driver to open, the first acquisition unit detects the voltage signal and current signal of channel 1, and the second acquisition unit detects the voltage signal and current signal of channels 2-5. If the judgment module determines that the voltage value of channel 1 is greater than 10v and the current value of channel 1 is greater than 100mA, it means that channel 1 of the solenoid valve driver has passed the test; if the judgment module determines that the voltage value of channel 1 is less than or equal to 0.5v and the current value of channel 1 is almost 0, it means that channel 1 of the solenoid valve driver has not passed the test. If channel 1 has not passed the test, the warning module issues a warning message; the second acquisition unit further detects the voltage signal and current signal of channels 2-5. If the judgment module determines that the voltage values ​​of channels 2-5 are all less than 0.5v and the current is almost 0, continue to control channel 2 to open; if the judgment module determines that the voltage value of a channel among channels 2-5 is greater than 10v and the current reaches 100mA, it means that the channel has not passed the test; the warning module issues a warning message;

[0085] Further, control channel 2 to open, the first acquisition unit detects the voltage signal and current signal of channel 2, and the second acquisition unit detects the voltage signal and current signal of channels 1 and 3-5. If the judgment module determines that the voltage value of channel 2 is greater than 10v and the current value of channel 2 is greater than 100mA, it means that channel 2 of the solenoid valve driver has passed the test; if the judgment module determines that the voltage value of channel 2 is less than or equal to 0.5v and the current value of channel 2 is almost 0, it means that channel 2 of the solenoid valve driver has not passed the test. If channel 2 has not passed the test, the warning module issues a warning message; the second acquisition unit further detects the voltage signal and current signal of channels 1 and 3-5. If the judgment module determines that the voltage values ​​of channels 1 and 3-5 are all less than 0.5v and the current is almost 0, continue to control channel 3 to open; if the judgment module determines that the voltage value of a channel among channels 1 and 3-5 is greater than 10v and the current reaches 100mA, it means that the channel has not passed the test; the warning module issues a warning message;

[0086] Further, channels 3 to 6 are opened in sequence, and the voltage and current of each channel are measured;

[0087] If all channels pass the test, it means that the solenoid valve driver passes the test.

[0088] In this embodiment, the channel to be tested of the solenoid valve driver is first determined, and then each channel to be tested is controlled to be opened in sequence. When each channel is opened in sequence, the voltage signal and current signal of the opened channel and the solenoid valve driver that remains closed are obtained in sequence, and the voltage signal and current signal data are analyzed to determine the test result of the solenoid valve driver. This test method does not require the setting of a companion test product. It only requires the solenoid valve driver to be tested to be connected to the host computer through the acquisition module. The test device corresponding to the test method has a simple structure, does not require the tester to have very professional operating skills and professional knowledge, and has a high degree of automation.

[0089] A third embodiment of the present disclosure provides a storage medium storing a computer program. When the computer program is executed by a processor, the steps of implementing the above method include:

[0090] S11: In response to the control instruction sent by the host computer, determine the channel to be tested of the solenoid valve driver;

[0091] S12: when the solenoid valve driver performs a target action, obtaining voltage signals and current signals of all the channels to be tested;

[0092] S13: Based on the voltage signal and the current signal, determine whether the solenoid valve driver passes the test.

[0093] Of course, other steps of the testing method of the above embodiment can also be used to implement the above embodiment.

[0094] In this embodiment, the channel to be tested of the solenoid valve driver is first determined, and then each channel to be tested is controlled to be opened in sequence. When each channel is opened in sequence, the voltage signal and current signal of the opened channel and the solenoid valve driver that remains closed are obtained in sequence, and the voltage signal and current signal data are analyzed to determine the test result of the solenoid valve driver. This test method does not require the setting of a companion test product. It only requires the solenoid valve driver to be tested to be connected to the host computer through the acquisition module. The test device corresponding to the test method has a simple structure, does not require the tester to have very professional operating skills and professional knowledge, and has a high degree of automation.
