[0041] <Hardware Configuration>

[0042] Figure 1 is a block diagram showing a hardware configuration of a test system that can implement an embodiment of the present disclosure.

[0043] like Figure 1 As shown, the test system 1000 may include a master control device 1100 and a plurality of test units 1200 , and each test unit 1200 may include a central control device 1210 and a plurality of measurement and control devices 1220 .

[0044] The master control device 1100 and each test unit 1200 can be connected to each other through a network. In each test unit 1200, the master control device 1200 and the measurement and control device 1220 can be connected to each other through a physical backplane, supporting hot plugging and not limiting the insertion position. Specifically, the backplane has hardware configurations such as a CAN bus and an IO bus, and the master control device 1200 and the measurement and control device 1220 in each test unit 1200 can communicate through a CAN bus, a backplane IO bus, and the like.

[0045] In one example, a test unit 1200 may be implemented by a test chassis.

[0046] In one embodiment, one test unit 1200 may be connected to at least one test fixture, and each test fixture may be provided with a plurality of devices under test.

[0047] In this embodiment, the test unit maps the test contacts and control contacts at the hardware level with the tested contacts derived from the device under test, and connects the corresponding contacts through connectors to form a test path, on which one or more test functions can be executed.

[0048] Furthermore, the devices under test placed in a test fixture may be regarded as a group of devices under test. Then, the devices under test in different groups may be subjected to asynchronous testing, and the devices under test in the same group may be subjected to synchronous testing.

[0049] This embodiment will hereinafter describe a process of testing a group of devices under test.

[0050] <Method Example>

[0051] The present disclosure provides a testing method, which may be implemented by a testing system including a centralized control device and a measurement and control device. Specifically, the testing system may be the testing system 1000 described in the aforementioned embodiment.

[0052] Figure 2 The figure is a flow chart of a testing method according to an embodiment of the present disclosure.

[0053] like Figure 2 As shown, the test method includes steps S2100 to S2300 as shown below:

[0054] Step S2100: The centralized control device obtains target test steps of the device under test, where the target test steps include multiple test steps in the test process tree.

[0055] In this embodiment, before executing step S2100, the method may further include: the master control device sends a test flow tree to the centralized control device and the test and control device in response to a test instruction for the device under test, and sends a target test step to the centralized control device.

[0056] In this embodiment, the tester may configure the test flow tree and the target test steps of the device under test in advance through the master control device before testing the device under test, wherein the target test steps may include a plurality of consecutive test steps in the test flow tree.

[0057] Specifically, the test process tree may include multiple test processes, each test process may include at least one test step, and the target test step may include multiple consecutive test steps in any test process.

[0058] Furthermore, each test flow may have a corresponding unique first identification code, and each test step in the test flow may have a corresponding second identification code and a number indicating the execution order of the test step in the corresponding test flow. For example, the number of the test step that is executed earlier may be smaller than the number of the test step that is executed later.

[0059] The master control device may send the test process tree to the centralized control device and the measurement and control device through the network, and send the target test steps to the centralized control device.

[0060] Step S2200: The centralized control device obtains a target test step from a plurality of test steps, generates a corresponding control instruction according to the target test step, and sends the control instruction to a plurality of measurement and control devices.

[0061] In one embodiment of the present disclosure, the centralized control device obtains a target test step from a plurality of test steps, including: the centralized control device traverses the plurality of test steps in order in a test process tree, and takes the currently traversed test step as the target test step.

[0062] In this embodiment, the centralized control device may traverse multiple test steps in order of numbers from small to large.

[0063] In another embodiment of the present disclosure, the centralized control device may also sequentially select multiple test steps as target test steps in ascending order of numbers.

[0064] In this embodiment, different test steps may be executed simultaneously or in sequence from smallest to largest number.

[0065] In one embodiment of the present disclosure, a control instruction corresponding to the target test step may be generated in the parser of the centralized control device. The control instruction may be an instruction for controlling the measurement and control device to execute the target test step, or may be an instruction for controlling the measurement and control device to stop executing the target test step.

[0066] In one embodiment of the present disclosure, the test process tree may also include an entry list corresponding to each test step, and each entry list may include list attributes and multiple test items, wherein the list attributes may include at least one of the following: attribute information indicating whether synchronization between measurement and control devices is required before executing the test items in the entry list, attribute information indicating how to synchronize between measurement and control devices, attribute information indicating whether a response is given after executing the test items in the entry list, etc.

[0067] In an embodiment in which the list attributes of the item list corresponding to the target test step include attribute information indicating that synchronization between measurement and control devices needs to be performed before executing the test items in the item list and attribute information indicating how to perform synchronization between the measurement and control devices, before the centralized control device generates the corresponding control instruction according to the target test step, the centralized control device can also generate a synchronization control instruction for controlling the synchronization of multiple measurement and control devices based on the attribute information indicating how to perform synchronization between the measurement and control devices, and send the synchronization control instruction to the multiple measurement and control devices. The test devices respond to the synchronization control instruction and perform synchronization based on the attribute information indicating how to perform synchronization between the measurement and control devices.

[0068] After the multiple test devices are synchronized, the centralized control device generates corresponding control instructions according to the target test steps, and sends the control instructions to the multiple measurement and control devices corresponding to the centralized control device. The multiple measurement and control devices corresponding to the centralized control device can be measurement and control devices connected to the centralized control device through a physical backplane.

[0069] Step S2300: The target measurement and control device executes a plurality of target test items corresponding to the target test steps in the test flow tree in response to the control instruction to test the device under test.

[0070] The target measurement and control device is a measurement and control device that matches the target test item among multiple measurement and control devices.

[0071] Through the embodiments of the present disclosure, the centralized control equipment and the measurement and control equipment test the device under test based on the test process tree, abstract the complex test process into fine-grained test items, and map the user test requirements to the control instructions that can be parsed and executed within the test system by constructing an engineering tree. This can reduce the design complexity, difficulty and development cost of the test process of the device under test and improve the reusability of the test system.

[0072] In one embodiment of the present disclosure, a test entry may include at least one of the following: an identifier of a functional channel, a start execution time relative to a previous test entry, an execution timeout, a return information description, an identification code of a corresponding measurement and control device, and a parameter function type.

[0073] In one embodiment, in order to make the field length of each test entry equal, a test entry may include: the identification of the functional channel, the start execution time relative to the previous test entry, the execution timeout time and the test parameter index, wherein the test parameter index can represent the storage address and length of the parameter block header such as the return information description, the identification of the test channel, the parameter function type, etc.

[0074] In this embodiment, each test item in each item list may have a corresponding third identification code and a number indicating the execution order of the test item in the item list, for example, the number of the test item with an earlier execution order may be smaller than the number of the test item with a later execution order.

[0075] In one example, multiple functional channels of the test system may be pre-set, and each functional channel may provide a type of function related to the test process, and the function is used to describe the acquisition or control function on the measurement and control equipment. For example, the functional channel may include voltage acquisition, current acquisition, sound signal acquisition, temperature signal acquisition, serial port acquisition, etc. Each functional channel has a corresponding unique identifier.

[0076] The identification of the functional channel in the test entry indicates that the test entry can be executed through the measurement and control equipment corresponding to the identified functional channel.

[0077] The execution start time relative to the previous test entry in a test entry indicates the time difference between the execution start time of the test entry and the execution start time of the previous test entry, and the execution start time relative to the previous test entry may be a non-negative number.

[0078] The execution timeout in a test entry means that the execution of the test entry is stopped when the execution time of the test entry reaches the execution timeout.

[0079] The return information description in the test entry indicates what kind of information is returned after the test entry is executed.

[0080] The ID of the test channel in the test entry indicates the ID of the test channel that can execute the test entry.

[0081] In this embodiment, one test channel corresponds to one device under test, and one or more functional channels can be mapped. Usually, one test channel includes multiple physical channels, and the multiple physical channels are connected to multiple test contacts of the device under test corresponding to one test channel through multiple lines. For example, one power physical channel can include one power supply function channel, one voltage acquisition function channel, and one current acquisition function channel.

[0082] In one embodiment of the present disclosure, each measurement and control device can, upon receiving a control instruction, obtain a target test entry corresponding to a target test step in a test process tree, and determine whether it is a measurement and control device that matches the target test entry; if so, it determines that it is a target measurement and control device, executes multiple target test entries corresponding to the target test step in the test process tree, and tests the device under test; if not, it determines that it is not a target measurement and control device, and there is no need to execute multiple target test entries corresponding to the target test step in the test process tree.

[0083] In this embodiment, the measurement and control device may determine whether it is a measurement and control device that matches the target test entry according to the identifier of the functional channel and / or the identifier of the test channel in the test entry.

[0084] In one embodiment of the present disclosure, the method also includes: any measurement and control device obtains an identification code of the measurement and control device corresponding to the target test entry as the target identification code based on the identification of the functional channel corresponding to the target test entry, the identification of the test channel, and a pre-set mapping table reflecting the mapping relationship between functional channels, measurement and control devices and measurement and control devices; and determines that it matches the target test entry when its own identification code matches the target identification code.

[0085] In this embodiment, a mapping table corresponding to the group of devices under test may be set in advance according to the settings of the measurement and control equipment, the devices under test, etc. The mapping table may reflect the mapping relationship between the functional channels, the test channels and the measurement and control equipment. In the mapping table of M rows and N columns, a row of elements corresponds to a functional channel, and a column of elements corresponds to a test channel. Then, the element in the i-th row and j-th column (where i is a positive number less than or equal to M, and j is a positive number less than or equal to N) may represent the information of the measurement and control equipment corresponding to the i-th functional channel and the j-th test channel. For example, it may include the type of the corresponding test equipment, the identification code of the corresponding measurement and control equipment, the identification of the i-th functional channel, etc.

[0086] Furthermore, in the mapping table, each row may have an identification of a functional channel, including the type and identification code of the measurement and control equipment, and the type and identification code of the supported functional channels.

[0087] Furthermore, the measurement and control device can obtain the identification code of the measurement and control device corresponding to the target test item according to the identification of the functional channel corresponding to the target test item, the identification of the test channel, and the mapping table. The identification code of the measurement and control device corresponding to the target test item may include the identification codes of one or more measurement and control devices.

[0088] The measurement and control device of this embodiment may determine that its own identification code matches the target identification code and that it matches the target test item when its own identification code is the same as any target identification code.

[0089] This embodiment incorporates the execution logic of the measurement and control equipment functions, test items and test processes into a unified description and management by constructing a mapping table and a test process tree, thereby effectively decoupling the system functions of each measurement and control equipment, effectively and flexibly decomposing test items, and constructing test logic, so that users can define test systems, customize test steps and parameters, etc. according to specific test requirements.

[0090] In one embodiment of the present disclosure, the method also includes: the target measurement and control device obtains the test data of the device under test corresponding to the target test item, and uploads the test data to the centralized control device; the centralized control device aggregates the test data uploaded by multiple target measurement and control devices to obtain aggregated test data, and uploads the aggregated test data to the master control device; the master control device obtains the test result of the device under test based on the aggregated test data.

[0091] In this embodiment, before aggregating the test data uploaded by multiple target measurement and control devices, the centralized control device may mark the test data uploaded by each target measurement and control device. Specifically, it may mark the identification code of the test device that returns the test data, the identification of the test channel corresponding to the test data, etc.

[0092] Furthermore, the master control device obtains the test result of the device under test according to the summarized test data, and may generate a test report according to the summarized test data.

[0093] Furthermore, the master control device may generate a test report in units of test steps or in units of test items, which is not limited here.

[0094] This embodiment can facilitate the user to trace the test results of the test device.
