DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0030] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0031] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0032] In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0033] It should be noted that due to space limitations, this application specification does not list all optional implementation methods. After reading this application specification, those skilled in the art should be able to think that as long as the technical features do not contradict each other, any combination of technical features can constitute an optional implementation method. Each embodiment is described in detail below.

[0034] At present, the test benches for PCBA (Printed Circuit Board Assembly) circuit boards and inverter levels are separate, and the test equipment is bulky and occupies a large area. For the test bench for circuit boards, all test requirements cannot be integrated. When testing PCBA, it is often necessary to expand the sub-control module. The reusability of the board-level test bench is low and the flexibility is poor. For the test bench at the inverter level, all test requirements cannot be integrated. When testing the inverter, a new project needs to expand the sub-control module. The reusability of the inverter-level test bench is low and the flexibility is poor.

[0035] In other words, the board-level test bench and the inverter-level test bench are separated, the test equipment is not unified, the test software has low adaptability, and the underlying test scripts need to be repeatedly developed. The current test bench is a customized device made only for automated testing, and it is impossible to flexibly switch between automated testing and manual verification testing, which makes troubleshooting inconvenient and the test efficiency low.

[0036] The present application provides a testing method, device, electronic device and storage medium for electric power equipment, aiming to solve the above technical problems in the prior art.

[0037] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0038] Figure 1 1 is a flow chart of a method for testing an electric device according to an embodiment of the present application, and the method can be performed by a testing device for an electric device. Figure 1 As shown, the method comprises the following steps:

[0039] S101. In response to a test instruction for an electric power device, obtain identification information of the electric power device.

[0040] Exemplarily, the power equipment may be a PCBA circuit board or an inverter or other equipment, that is, different types of power equipment may be tested. A host computer may be used for testing, and the host computer includes a code program for controlling the steps in the test method. The user may connect the host computer to the power equipment, for example, the host computer may be connected to the power equipment through a hardware controller, and the controller includes multiple interfaces that may be used to connect circuit boards, inverters, host computers, low-voltage power supplies, high-voltage power supplies, multimeters, signal simulators, and the like. The user may issue a test instruction to the host computer, instructing the host computer to test the power equipment.

[0041] Different power equipment may correspond to different identification information, which may be unique identification information corresponding to each power equipment or unique identification information corresponding to each equipment type. The user may upload the identification information of the power equipment in the host computer, and directly obtain the identification information of the power equipment after responding to the test instruction of the power equipment. Each power equipment may also store its own identification information, and after responding to the test instruction of the power equipment, the host computer may read the identification information of the power equipment from the power equipment.

[0042] In this embodiment, in response to a test instruction for the power equipment, identification information of the power equipment is obtained, including: in response to a test instruction for the power equipment, test configuration information of the power equipment is obtained; wherein the test configuration information represents electrical properties of the power equipment; and characters located at a preset position are obtained from the test configuration information as identification information of the power equipment.

[0043] Specifically, each power device has its own test configuration information, which may include various electrical properties of the power device, such as resistance value, voltage value, current value, etc. The user may upload the test configuration information to the host computer, and the test configuration information may also be pre-stored in each power device.

[0044] After responding to the test instruction for the power device, the host computer can obtain the test configuration information of the power device. For example, the test configuration information can be obtained from the power device through the connected controller. The configuration information contains a character string, and the identification information is located in the character string. The position of the identification information in the test configuration information can be preset, and the characters at the position can be obtained as the identification information of the power device. For example, the last two characters can be obtained from the test configuration information as the identification information.

[0045] The beneficial effect of such a setting is that the characters at the preset position are obtained as identification information of the object under test, the object under test is confirmed, different power equipment can be tested, and the accuracy and flexibility of the test are improved.

[0046] S102. Call test parameters of the power equipment according to identification information of the power equipment; wherein the test parameters represent electrical performance of the power equipment.

[0047] Exemplarily, the identification information can be used to characterize the device type of the power device. For example, if the identification information is 0, the power device is a circuit board; if the identification information is 1, the power device is an inverter. Different test parameters can be called for power devices with different identification information. That is, different test parameters can correspond to different device types, and the test parameters are power-related parameters used for testing.

[0048] According to the equipment type represented by the identification information of the electric equipment, the test parameters corresponding to the electric equipment are determined, and the test parameters are retrieved for subsequent testing.

[0049] In this embodiment, the test parameters of the power equipment are called according to the identification information of the power equipment, including: determining the parameter type corresponding to the identification information of the power equipment as the target type according to a preset association relationship; wherein the preset association relationship represents the association relationship between the identification information and the parameter type; and obtaining the parameters corresponding to the target type from the test configuration information as the test parameters of the power equipment.

[0050] Specifically, the association between the identification information and the parameter type is pre-set and stored, and the parameter type related to the identification information of the power equipment is searched as the target type. The specific parameter value corresponding to the target type is obtained from the test configuration information as the test parameter of the power equipment. For example, for the inverter equipment, the corresponding target type has a resistance value and a maximum current value, and the specific resistance value and the maximum current value can be obtained from the test configuration information. The test parameters can also be manually uploaded to the host computer, and the host computer can obtain them.

[0051] The beneficial effect of such a setting is that different types of equipment correspond to different parameters, which enables targeted testing of different types of power equipment and improves the accuracy and flexibility of the test.

[0052] S103: Test the electric power equipment according to the identification information and test parameters of the electric power equipment, and generate and output a test report of the electric power equipment.

[0053] Exemplarily, based on the identification information of the power equipment, the test methods corresponding to different identification information are determined, that is, different equipment types may correspond to different test methods, for example, for circuit board equipment, communication test and circuit test may be performed; for inverter equipment, overcurrent test and overvoltage test may be performed. The test parameters used for different tests may be different, that is, the power equipment may be tested in a targeted manner based on the test parameters and the equipment type represented by the identification information.

[0054] An automated test report can be generated based on the test results, and the host computer can output the test report for the user to view. A power device can perform many different types of tests, and the test report can include the results of each test, or the comprehensive test results of the power device. The test report can be displayed on a visual interface, or stored in a preset storage path.

[0055] In an embodiment of the present application, identification information of the power equipment is determined by responding to a test instruction for the power equipment. According to different identification information, the test parameters of the power equipment are called, that is, different power equipment corresponds to different test parameters, so as to implement targeted testing of different power equipment and improve the compatibility of the test. According to the identification information and test parameters of the power equipment, the power equipment is tested, and a test report of the power equipment is generated and output. By distinguishing different electronic devices and calling different test parameters, there is no need to switch test benches, which saves manpower and time and improves the flexibility and efficiency of the test.

[0056] Figure 2 A flow chart of a method for testing electric equipment provided in an embodiment of the present application is an optional embodiment based on the above-mentioned embodiment.

[0057] In this embodiment, the power equipment is tested according to the identification information and test parameters of the power equipment, and a test report of the power equipment is generated and output, including: performing a low-voltage test on the power equipment according to the test parameters of the power equipment to obtain a low-voltage test result; performing a high-voltage test on the power equipment according to the identification information and test parameters of the power equipment to obtain a high-voltage test result; and generating and outputting a test report of the power equipment based on the low-voltage test result and the high-voltage test result.

[0058] like Figure 2 As shown, the method comprises the following steps:

[0059] S201. In response to a test instruction for an electric power device, obtain identification information of the electric power device.

[0060] Exemplarily, this step may refer to the above-mentioned step S101 and will not be described in detail.

[0061] S202. Call test parameters of the power equipment according to identification information of the power equipment; wherein the test parameters represent electrical performance of the power equipment.

[0062] Exemplarily, this step may refer to the above-mentioned step S102 and will not be described in detail.

[0063] S203. Perform a low voltage test on the electric equipment according to the test parameters of the electric equipment to obtain a low voltage test result.

[0064] Exemplarily, a low voltage test can be performed on the power equipment. The low voltage test generally refers to a test performed on the electrical equipment or system under relatively low voltage conditions. The purpose of this test is to ensure that the equipment or system can still work normally under low voltage conditions, or that no failure occurs under low voltage conditions. In this embodiment, the specific test scheme for the low voltage test is not specifically limited. For example, the minimum voltage that the power equipment can withstand can be determined based on the test parameters, and the voltage can be applied to the power equipment to detect the operating status of the power equipment. For different power equipment, information such as the test scheme or test strategy of the power equipment can be determined based on the test parameters of the power equipment, and the power equipment can be subjected to a low voltage test. The result obtained after the low voltage test is determined as the low voltage test result.

[0065] In this embodiment, a low voltage test is performed on the power equipment according to the test parameters of the power equipment to obtain a low voltage test result, including: determining a test version of the power equipment; wherein the test version represents the software version currently used by the power equipment; according to the test parameters and test version of the power equipment, a low voltage test is performed on the power equipment to obtain a low voltage test result; wherein the low voltage test includes at least one of a communication test, a control chip pin reading test, an integrated circuit test, and a circuit safety test.

[0066] Specifically, when conducting a low-voltage test, the software version can be confirmed first, that is, the test version can be determined. Different software versions can correspond to different test schemes. The current software version can be read from the power equipment, or the user can upload the test version to the host computer. After determining the test version, the power equipment can be subjected to targeted low-voltage testing based on the test parameters and the test version. For different types of power equipment, the test version can be determined first, and then the test can be performed. The test parameters required for different test versions can be the same or different. For different test versions, the processing process for the same test parameters can also be different.

[0067] There can be many types of low-voltage tests. For example, low-voltage tests may include communication tests, control chip pin reading tests, IO (Input / Output) circuit tests, Safety (safety) circuit tests, etc. Among them, IO circuit test is integrated circuit test, and Safety circuit test is circuit safety test. In this embodiment, the test order of various low-voltage tests is not specifically limited. For example, a communication test can be performed first, followed by a main control chip ADC (Analog-to-Digital Converter) pin reading test, followed by an IO circuit test, and finally a Safety circuit test. The low-voltage test results may include the test results of all low-voltage tests.

[0068] For different types of electrical equipment, the types of low voltage tests can be the same or different.

[0069] The beneficial effect of such a setting is that, in the low-voltage test, the software version is first confirmed and then tested, thereby achieving flexible switching of tests for different software versions and improving the accuracy and efficiency of the test.

[0070] In this embodiment, determining the test version of the power device includes: determining the power-on time of the power device; if the power-on time reaches a preset time window length, reading the test version of the power device.

[0071] Specifically, in the low voltage test, the software version is first confirmed. The current software version can be automatically obtained through the host computer as the test version. The host computer can also be manually controlled to read the current software version from the power equipment as the test version.

[0072] A time window length is preset, for example, the preset time window length is 30ms. Within 30ms, i.e., the preset time window length, after the power device is powered on, the host computer sends a command to the power device to enter the repair mode. The power device enters the repair mode, and the host computer reads the software version information, i.e., determines the test version. In other words, after the power device is powered on, the power-on maintenance time can be recorded in real time to determine whether the power-on time reaches the preset time window length, so as to avoid reading the test version after the time window length, which may cause reading errors.

[0073] The host computer can also store a standard software version in advance. After determining the test version, the test version can be compared with the standard software version. If it is determined that the test version is the standard software version, the subsequent test can be continued; if it is determined that the test version is not the standard software version, the test can be considered to have failed, and a test report of the test failure can be generated.

[0074] The beneficial effect of such a setting is that by automatically reading the software version information within a period of time after power-on, the controllability of the test can be improved, the problems of uncontrollable time of manual testing and poor test feasibility can be avoided, and the accuracy of the test can be effectively improved.

[0075] S204: Perform a high voltage test on the electric equipment according to the identification information and test parameters of the electric equipment to obtain a high voltage test result.

[0076] Exemplarily, the electrical equipment may be subjected to a low voltage test and a high voltage test. In this embodiment, the order of the low voltage test and the high voltage test is not specifically limited. For example, the low voltage test may be performed first, and then the high voltage test. High voltage testing generally refers to testing of electrical equipment or systems under higher voltage conditions.

[0077] The high voltage tests performed on different types of power equipment may be different. That is, the type of the power equipment may be determined based on the identification information of the power equipment, and then the high voltage test may be performed on the power equipment based on the type of the power equipment and the test parameters to obtain the test results of the high voltage test. In this embodiment, the test scheme and test strategy of the high voltage test are not specifically limited.

[0078] In this embodiment, a high-voltage test is performed on the power equipment according to the identification information and test parameters of the power equipment to obtain a high-voltage test result, including: if it is determined that the device type of the power equipment is a single-board device according to the identification information of the power equipment, then a first high-voltage test is performed on the power equipment according to the test parameters of the power equipment to obtain a high-voltage test result; wherein the first high-voltage test includes a high-voltage sampling test and a high-voltage drive test; if it is determined that the device type of the power equipment is an inverter device according to the identification information of the power equipment, then a second high-voltage test is performed on the power equipment according to the test parameters of the power equipment to obtain a high-voltage test result; wherein the second high-voltage test includes at least one of a high-voltage sampling test, a high-voltage drive test, a current calibration test, an over-current test, an over-voltage test, and an output power test.

[0079] Specifically, different types of power equipment correspond to different high-voltage tests. For example, a single-board device corresponds to a first high-voltage test, and an inverter device corresponds to a second high-voltage test. A single-board device is a PCBA circuit board device. The first high-voltage test may include a high-voltage sampling test and a high-voltage drive test, and the second high-voltage test may include a high-voltage sampling test, a high-voltage drive test, a current calibration test, an overcurrent test, an overvoltage test, an output power test, and the like.

[0080] After obtaining the identification information of the power equipment, the device type of the power equipment is first determined according to the identification information, and the high-voltage test corresponding to the power equipment is determined according to the association between the preset device type and the high-voltage test. The high-voltage test corresponding to the power equipment is the first high-voltage test or the second high-voltage test. If the device type of the power equipment is determined to be a single-board device, the first high-voltage test is performed on the power equipment according to the test parameters of the power equipment to obtain the high-voltage test result; if the device type of the power equipment is determined to be an inverter device, the second high-voltage test is performed on the power equipment according to the test parameters of the power equipment to obtain the high-voltage test result.

[0081] Figure 3 Schematic diagram of the high voltage test process. Figure 3 For single-board equipment, there is no specific limitation on the test sequence between the high-voltage sampling test and the high-voltage drive test; for inverter equipment, there is no specific limitation on the test sequence between the high-voltage sampling test, high-voltage drive test, current calibration test, over-current test, over-voltage test, and output power test.

[0082] High-voltage sampling test mainly involves measuring and analyzing the electrical parameters of equipment or systems under high voltage conditions. Its purpose is: 1. Measuring electrical parameters: collecting parameters such as current, voltage, power factor, etc. under high voltage to evaluate the performance of the equipment; 2. Verifying equipment stability: ensuring that the equipment can operate stably under high voltage conditions without abnormal fluctuations or failures; 3. Detecting insulation performance: by testing under high voltage conditions, check whether the insulation materials and structures of the equipment can effectively prevent leakage or breakdown, etc. High-voltage drive testing refers to operating the equipment under high voltage conditions to evaluate its function and reliability under high voltage. Its purpose is: 1. Functional verification: ensuring that the equipment can perform its intended function normally under high voltage conditions; 2. Withstand voltage test: verify the withstand voltage capability of the equipment under high voltage to ensure that electrical breakdown does not occur; 3. Reliability test: evaluate the reliability and durability of the equipment under long-term operation under high voltage, etc. Current calibration testing is a test process used to ensure the accuracy of current measuring devices (such as ammeters, current sensors or current transformers, etc.). The purpose of calibration testing is to verify and adjust the output of the measuring device to meet the expected precision and accuracy requirements by comparing it with a known standard. Overcurrent testing refers to the test conducted when the current value flowing through electrical equipment or cable lines exceeds their rated current when a short circuit, overload or phase loss occurs in the circuit. Overvoltage testing refers to the application of a voltage higher than its normal operating voltage to electrical equipment, electronic components or systems to evaluate their performance and tolerance under abnormal voltage conditions. The purpose of this test is to ensure that the equipment will not fail or be damaged in the event of unexpected voltage spikes or excessive voltage, thereby improving its reliability and safety. Output power testing refers to measuring the power output of a device or system under specific conditions to ensure that it meets design specifications and performance requirements. This test is often used to evaluate the efficiency, performance and stability of the equipment.

[0083] The beneficial effect of such an arrangement is that different types of high voltage tests can be performed on different power equipment, and flexible switching of tests on different equipment can be achieved, thereby improving the efficiency and accuracy of the test.

[0084] In this embodiment, the second high-voltage test is an overcurrent test, and the test parameters of the power equipment include a current threshold range, a temperature threshold range, and a test number, and the high-voltage test result includes an overcurrent point current; according to the test parameters of the power equipment, a second high-voltage test is performed on the power equipment to obtain a high-voltage test result, including: supplying power to the power equipment within the current threshold range, and recording the current power supply current and the number of power supplies; obtaining the current temperature information of the power equipment, if the current temperature information is within the temperature threshold range, and the number of power supplies is less than or equal to the test number, determining whether the power equipment has an overcurrent fault; if it is determined that the power equipment has an overcurrent fault, determining that the power supply current is the overcurrent point current.

[0085] Specifically, for inverter equipment, the second high-voltage test includes an overcurrent test. Overcurrent refers to the phenomenon that the current value flowing through electrical equipment or cable lines exceeds their rated current when a short circuit, overload or phase failure occurs in the circuit. When performing an overcurrent test, the required test parameters may include a current threshold range, a temperature threshold range, and the number of tests. The current threshold range, the temperature threshold range, and the number of tests are all preset values. The current threshold range refers to the current range allowed to be applied to the power equipment, the temperature threshold range refers to the temperature range of the power equipment under normal conditions, and the number of tests refers to the maximum number of times the power equipment is allowed to be tested for overcurrent.

[0086] A current value is determined within the current threshold range as the power supply current to supply power to the power device. For example, the power supply to the power device can be started from the lower limit of the current threshold range, and the current power supply current and the number of power supply times are recorded. For example, when powering on for the first time, the power supply current is the lower limit value of the current threshold range, and the number of power supply times is 1.

[0087] Monitor the current temperature information of the power equipment in real time, and determine whether the current temperature information is within the temperature threshold range. If not, it is considered that the power equipment is abnormal and the test fails; if so, determine whether the current power supply times are less than or equal to the preset test times. If the current power supply times exceed the preset test times, the test is determined to have failed. If the current temperature information is within the temperature threshold range, and the power supply times are less than or equal to the test times, further monitor to determine whether the power equipment has an overcurrent fault. If it is determined that there is an overcurrent fault, the current supply current is determined as the current of the overcurrent point, and a high-voltage test result is generated. The overcurrent point current needs to be stated in the high-voltage test result; if it is determined that there is no overcurrent fault, adjust the size of the supply current and apply it to the power equipment again. For example, it can start from the lower limit value and increase by 1A each time, and the power supply times are increased by one each time. If the supply current exceeds the preset current threshold range, the current temperature information exceeds the temperature threshold range, or the power supply times exceed the test times, it can be considered that the overcurrent test has failed. Only when the supply current is within the current threshold range, the current temperature information is within the temperature threshold range, and the power supply times do not exceed the test times, the overcurrent point current will be determined when an overcurrent fault occurs.

[0088] In this embodiment, the power supply current for each time can be calculated according to the preset current threshold range and the number of power supply times. The calculation formula of the power supply current can be:

[0089] I c =I c1 +1 / n×(I c2 -I c1 )×m;

[0090] Among them, Ic is the supply current, I c1 is the lower limit of the current threshold range, I c2 is the upper limit of the current threshold range, n is the preset number of tests, and m is the current number of power supplies.

[0091] The beneficial effect of such a setting is that the manual overcurrent test has defects such as large stress impact on the inverter drive module. In this embodiment, the overcurrent test monitors the temperature of all temperature sensors, the given size of the power supply current, and the number of times the power supply current is adjusted. If any of the monitored objects exceeds the standard, the overcurrent test will be stopped, realizing an overcurrent test with protection, while improving the test efficiency and protecting the inverter.

[0092] S205. Generate and output a test report of the power equipment according to the low voltage test results and the high voltage test results.

[0093] Exemplarily, the low voltage test result and the high voltage test result are combined to obtain a test report of the electric power equipment, that is, the test report may include the low voltage test result and the high voltage test result.

[0094] Figure 4 Schematic diagram of the process of testing electrical equipment. Figure 4 In the process, first determine the test object, that is, determine the equipment type of the power equipment. For single-board equipment, call the test parameters, perform low-voltage test and high-voltage test, and finally output the test results.
