[0059] The exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, descriptions of well-known functions and structures are omitted in the following description for clarity and conciseness.

[0060] The method, device, and system for electric drive testing according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0061] Figure 1 It is a schematic flowchart of a method for electric drive testing provided by an embodiment of the present disclosure.

[0062] As Figure 1 shown, the method includes the following steps:

[0063] Step 101, in response to a script program instruction for testing a target to be detected configured in advance, call a corresponding device driver according to the identification information of the target test device corresponding to the target to be detected. The script program instruction includes the identification information of the target test device, and the target test device is used to test the target to be detected.

[0064] In the embodiment of the present disclosure, the script program instruction is a custom - edited instruction, and the editing methods include but are not limited to: Json language, c++, c language, etc. After the script program instruction is edited, it is parsed by a custom - set script interpreter, and directly calls the device driver to replace the traditional graphical programming architecture. That is, all test instruments are abstracted into each control object, and the object and the corresponding device remote instruction are wrapped using languages such as Json to form a script. The entire test process is completed by arranging the execution order of remote objects in the script. Since all test execution actions are described in the script, the Central Processing Unit (CPU) only needs to interpret the script to complete the entire test process, without the need for multi - layer calls from graphics to function libraries to communication, greatly improving the test speed and realizing high - speed electric drive offline testing.

[0065] Among them, the identification information of the target test device is a unique representation for indicating the identity of the target test device, that is, the identity document number (Identity document, ID). The target test device is an instrument for testing the target to be detected, such as: low - voltage power supply, oscilloscope, digital multimeter, digital IO card, etc.

[0066] Step 102: Control the device driver to turn on the corresponding target test device, and test the target to be detected to obtain an initial test result.

[0067] In the embodiments of the present disclosure, the connection manner between the device driver and the corresponding target test device includes but is not limited to: wireless connection, wired physical connection, etc. Among them, the device driver exists in the CPU. For example, it is connected to the CPU through the physical connection line of each target test device, and the CPU can remotely access the corresponding test instrument through the corresponding device driver. At the same time, all the target test devices are configured in the test fixture.

[0068] Step 103: Based on the script program instructions, verify the initial test result with the expected test result, and obtain the corresponding electric drive test result based on the verification result. The expected test result is the expected result for the target to be detected custom-configured in the script program instructions.

[0069] In the embodiments of the present disclosure, the verification process includes but is not limited to: comparison process, calculation process, etc. The expected test result is a custom-set result. For example, the script program instructions are:

[0070]

[0071]

[0072] Among them, the content in "Expectation" represents the expected object, "Target" represents the test expectation, "Operator": 4 represents the expected logical processing method (for example: the range is left-closed and right-open), the content in "Value" represents the range (greater than or equal to the minimum value of 1.23 and less than the maximum value of 4.56), the content in "Source" represents the target to be detected, "Analysis": 1 means that the test method for the target to be detected is to collect the maximum value of the target test device's test on the target to be detected, and the content in "RemoteCmd" represents the target test device and the instructions executed on the target test device. Among them, "ClientName": "Multimeter" means that the name of the target test device is a digital multimeter, "Type": "r" means reading the value of the digital multimeter, and "Cmd": "READ?\n" means the instrument reading command.

[0073] For ease of understanding, embodiments of the present disclosure provide an example for illustration: If the voltage of the target to be detected is required, the expected test result is a voltage of 12V - 24V, and the initial test result is a voltage of 20V. At this time, since the initial test result is within the range of the expected test result, the electric drive test result is that the voltage is qualified, the voltage conforms to the specification, etc.; If the voltage of the target to be detected is required, the expected test result is a voltage of 12V - 24V, and the initial test result is a voltage of 28V. At this time, since the initial test result is not within the range of the expected test result, the electric drive test result is that the voltage is unqualified, the voltage does not conform to the specification, etc. Among them, the form and content of the electric drive test result can be determined according to the actual test situation, and the embodiments of the present disclosure do not limit it.

[0074] It should be noted here that in the overall electric drive test process, it includes three major parts: Pre_Cond, Steps, and Expectation. Among them, Pre_Cond represents the preset conditions for the test, initializing the tooling before the test, that is, the corresponding initialization script instructions; Steps represents the specific test steps, that is, the corresponding control instructions, and Expectation describes the test expectation, verifying the test value collected in the test and the expected value of the test, that is, the expected test result. Specifically, as shown in the following script program instructions:

[0075]

[0076] By defining these three parts of "Pre_Cond", "Steps", and "Expectation", the specific test process can be described, and the specific content of each part is described using remote objects or local objects. Taking remote objects as an example: As shown in the following script program instructions:

[0077]

[0078] Among them, "Type": "w" means writing to the digital multimeter, and "Cmd": "*RST\n" means the reset instruction of the digital multimeter.

[0079] This part describes controlling a remote object: the digital multimeter, and sending a reset command ("Cmd": "*RST\n") to it through its driver. Therefore, if you want to read data from the instrument later, you only need to change Type to r and Cmd to the corresponding read command. The above realizes the sending and collection of data.

[0080] The method for electric drive testing provided by the present disclosure responds to the script program instructions of the target test device corresponding to the target to be detected, calls the corresponding device driver according to the identification information of the target test device, and the script program instructions include the identification information of the target test device, and the target test device is used to test the target to be detected; controls the device driver to turn on the corresponding target test device, and tests the target to be detected to obtain an initial test result; performs a verification process on the initial test result and the expected test result, and obtains a corresponding electric drive test result based on the verification result, and the expected test result is a pre-customized expected result for the target to be detected. Compared with the related art, the embodiment of the present disclosure replaces the traditional graphical programming architecture and function library method by directly programming the target test device and the script program instructions, meets the requirements of the off-line test of the electric drive controller, and has the characteristics of high test efficiency, good scalability, good replicability, and easy use.

[0081] In an implementable manner of the embodiment of the present disclosure, before testing the target to be detected, it is necessary to connect the circuit loop between the target test device and the target to be detected, so as to smoothly complete the test of the target to be detected. Therefore, in order to control the on / off of the circuit loop between the target test device and the target to be detected and accurately test the target to be detected, the embodiment of the present disclosure provides a schematic flow diagram of a control loop, as Figure 2 shown, including:

[0082] Step 201, based on the script program instructions, determine the first port information of the target to be detected and the second port information of the target test device corresponding to the first port information, where the script program instructions include different first port information and corresponding second port information.

[0083] In the embodiment of the present disclosure, the second port information includes but is not limited to: the name of the target test device, the port number of the target test device, the signal corresponding to each port of the target test device, etc., and the first port information includes but is not limited to: the port number of the target to be detected, etc., and can also represent the position to be detected by the probe of the target test device, as shown in Table 1,

[0084] Table 1

[0085]

[0086] Among them, the device for controlling the on / off of the control loop is a digital IO card. Serial number: PCI-7444-DO0 indicates that the name of the target test device of the digital IO card is PCI-7444 (board 7444). The programmer connector and the PCBA test point: The description is which Port (point position) on the PCI-7444. Signal: Which path on the described Port. Test point 1 and test point 2 (target points to be detected) respectively correspond to which probe of which test instrument at the other end. The specific command format is shown in the following script program instructions:

[0087]

[0088] Step 202: Connect the circuit between the port corresponding to the first port information and the port corresponding to the second port information.

[0089] In the embodiment of the present disclosure, the preset relay device is a device selected by custom, such as a relay box, etc. For the hardware loop, the relay box is operated by controlling the digital IO card, so as to control which loop each probe of the instrument is specifically connected to. As shown in Table 1, according to the port definitions of the board and the relay box, one end of the relay box is connected to the test point of each path of the target to be detected, and the other end is connected to the probes of all target test devices. By controlling the opening and closing of the relay box through the digital IO card, the on / off of the circuit loop between the target test device and the target to be detected is realized.

[0090] In an implementable manner of the embodiment of the present disclosure, it is necessary to initialize the target test device to reduce errors during testing. Therefore, in order to improve the accuracy of the electric drive detection, the following methods can also be used but are not limited to: Obtain the initialization script instruction of the target test device corresponding to the target to be detected edited by a preset editing method. The initialization script instruction includes the initialization information customized in advance for the target test device; According to the initialization information, perform an initialization operation on the target test device.

[0091] In the embodiment of the present disclosure, the preset editing method is an editing method selected by custom, such as Json language, c++, c language, etc. The initialization information includes the instruction of the target value to be achieved by the target test device. For example, when the target test device is a digital multimeter, the initialization information includes an instruction to reset the digital multimeter, that is, an instruction to zero the value of the digital multimeter. Specifically, the content of the initialization information and the preset editing method can be determined according to the actual situation, and the embodiment of the present disclosure does not limit them.

[0092] In an implementable manner of the embodiments of the present disclosure, the script program instruction is a custom - edited instruction, and the editing methods include but are not limited to: Json language, c++, c language, etc. Therefore, before performing the electric drive test, it is necessary to first write the corresponding script file. In order to complete the electric drive test, the following methods can also be used but are not limited to: obtaining the script program instruction for detecting the target to be detected edited by the preset editing method.

[0093] In an implementable manner of the embodiments of the present disclosure, it is necessary to establish the corresponding relationship between the target test device and the device driver in advance before the corresponding device driver can be called. Therefore, in order to successfully call the device driver, the following methods can also be used but are not limited to: searching for the device driver corresponding to the target test device according to the corresponding relationship between the identification information of the target test device and the device driver established in advance.
