[0002] The power data acquisition terminal is an intelligent data acquisition and control terminal device installed in a dedicated or public transformer substation, with a series of functions such as power metering, data acquisition, distribution transformer monitoring, and power management.

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] Example 1

[0039] Figure 1 A terminal testing device is shown, including a testing device and a detection tool, the detection tool includes N virtual modules and a transfer control module, and the testing device includes a virtual terminal. The terminal testing device is used to perform a whole machine test and a terminal interface test on the whole machine to be tested. The whole machine to be tested usually includes a body and multiple functional modules. The number of virtual modules is the same as the number of functional modules, and N is a positive integer. For example, when the number of functional modules is 3, the value of N can be 3.

[0040] Virtual modules are used to simulate functional modules in the whole machine under test, such as remote communication modules, local communication modules, etc., so as to replace the real modules under test during the test process. Virtual modules can simulate various possible input and output situations, helping testers to more comprehensively evaluate the performance and stability of the whole machine under test. Moreover, the same virtual module can detect terminals of different specifications and interfaces, which not only improves the flexibility of the test, but also reduces the dependence on the actual hardware, thereby reducing the test cost and improving the integrated detection capability and automation level.

[0041] The virtual terminal is used to simulate the main body of the whole machine under test and communicate with the module under test. The virtual terminal can send test instructions, receive test results, and monitor the test progress in real time during the test. In addition, the virtual terminal can also simulate a variety of communication protocols and interface standards to meet the test requirements of different modules under test.

[0042] Specifically, when the terminal interface test is performed on the whole machine to be tested, the terminal interface to be tested can be connected to the first end of the transfer control module through the first transfer line, the first end of each virtual module is connected to the second end of the transfer control module, and the second end of each virtual module is connected to the test equipment. During the formal test, the test equipment switches the virtual module to the terminal interface to be tested, and waits for the terminal interface to be tested to identify each virtual module one by one. The test equipment switches the virtual module to the terminal interface to be tested, that is, the test equipment controls the communication between the transfer control module and the terminal interface to be tested through its built-in control logic, and disconnects the communication with the module interface to be tested, so as to realize the connection between the virtual module and the terminal interface to be tested. The "switching" here can be understood as a configuration change inside the test equipment, which enables the terminal interface to be tested to recognize and communicate with the virtual module, rather than the actual module to be tested. In this way, the test equipment can simulate different test scenarios and verify the recognition ability and compatibility of the terminal interface to be tested for different virtual modules. After successful identification, the virtual module tells the test device that it has been successfully identified by the terminal interface under test. After that, the test device will establish a virtual module module mapping, which records the types of all successfully identified virtual modules, thereby realizing the connection between the virtual module and the test device. Subsequently, the test device loads the test case and distributes it to each virtual module for execution through the virtual module mapping. During the test, the test device will receive and summarize the test progress and results in real time.

[0043] In addition, when the number of the whole machines to be tested is at least one, the virtual module can be reused to perform a one-to-many serial test. Exemplarily, when performing a terminal interface test on M whole machines to be tested, the test equipment first controls the first end of the switching control module to connect to the terminal interface to be tested in the whole machine 1 to be tested, and the second end to connect to the virtual module, and the virtual module to connect to the test equipment. After the whole machine 1 to be tested completes the terminal interface test, the test equipment controls the first end of the switching control module to connect to the terminal interface to be tested in the whole machine 2 to be tested, and performs a terminal interface test on the whole machine 2 to be tested. Similarly, after the whole machine M-1 to be tested completes the terminal interface test, the test equipment controls the first end of the switching control module to connect to the terminal interface to be tested in the whole machine M to be tested, and performs a terminal interface test on the whole machine M to be tested.

[0044] When performing the terminal whole machine test, that is, checking whether the entire terminal device is working properly, the virtual module and the virtual terminal will be disabled, and the module to be tested will be directly plugged into the interface of the whole machine to be tested. At this time, the first end of the transfer control module is connected to the terminal interface to be tested in the whole machine to be tested, and the second end is connected to the module to be tested. During the formal test, first, the test equipment switches the interface of the module to be tested to the terminal to be tested. The switching here also refers to a configuration change inside the test equipment, which enables the interface of the module to be tested to communicate directly with the terminal to be tested in order to perform whole machine testing. Secondly, the test equipment sends the whole machine test plan to the whole machine to be tested, the whole machine to be tested executes the whole machine test plan, and feeds back the whole machine test results to the test equipment.

[0045] When executing the module interface test, that is, checking whether the module interface is working properly, the first end of the transfer control module is connected to the interface of the module to be tested in the whole machine to be tested through the second transfer line, and the second end is connected to the virtual terminal. During the formal test, the test equipment switches the interface of the module to be tested to the virtual terminal, that is, controls the communication between the transfer control module and the interface of the module to be tested and the virtual terminal, and disconnects the communication between the terminal interface to be tested and the virtual module. The virtual terminal can simulate the actual communication protocol and interface standard to interact with the interface of the module to be tested. The test equipment controls the virtual terminal to identify the type of the module to be tested, and the test equipment sends the test case to the virtual terminal. The virtual terminal sends the test case to the module to be tested for testing, and sends the test progress and results to the test equipment. The test equipment summarizes the test results.

[0046] Furthermore, in order to adapt to the whole machine to be tested with different structures and interfaces, it is only necessary to configure the corresponding adapter cable to easily achieve compatibility. Specifically, the first adapter cable and the second adapter cable can be selected from a variety of types, including but not limited to USB cables, RS232 communication cables, etc., thereby ensuring the stability and compatibility of data transmission. In addition, the connection between the detection tooling and the test equipment, and between the whole machine to be tested and the test equipment is also extremely flexible, supporting serial ports, networks, Bluetooth, CAN and other communication methods, further improving the flexibility and scope of application of the test, so that it can meet more diverse test needs.

[0047] The terminal testing device in this embodiment realizes whole machine testing and interface testing of the terminal in the same testing device by connecting the first end of the switching control module to the terminal interface to be tested in the whole machine to be tested, and connecting the second end to the module to be tested, and connecting the whole machine to the testing equipment when performing whole machine testing; and by connecting the first end of the switching control module to the terminal interface to be tested, and connecting the second end to the virtual module, and connecting the virtual module to the testing equipment when performing terminal interface testing, thereby realizing seamless switching between whole machine testing and interface testing through the switching control module, improving the automation level of terminal testing, significantly improving testing efficiency, and effectively reducing testing costs.

[0048] Example 2

[0049] like Figure 1 As shown, the present embodiment also provides a terminal testing system, including M whole machines to be tested, M detection fixtures and test equipment. Wherein, M is a positive integer. The M whole machines to be tested each include a terminal interface to be tested and N module interfaces to be tested, the M detection fixtures each include N virtual modules and a switching control module, and the test equipment includes M virtual terminals, and the M virtual terminals correspond to the M whole machines to be tested respectively. Optionally, the M whole machines to be tested can perform terminal whole machine testing, terminal interface testing and module interface testing at the same time, or they can be performed in sequence. In particular, when the terminal interface test is performed on the M whole machines to be tested, the test equipment establishes corresponding virtual module mappings for the N virtual modules in the M detection fixtures to ensure the smooth progress of the test and improve reliability.

[0050] The terminal test system in this embodiment, by separating the body and the module of the whole machine to be tested, not only does the system not need to pay attention to the specific size of the virtual terminal and the virtual module, but also cleverly uses the control module in the adapter and the test equipment to realize the automatic switching of the whole machine body between the actual module and the virtual module. This feature greatly enhances the flexibility of the system. Furthermore, since a single virtual module can adapt to terminals of various specifications and interfaces for detection, this not only greatly reduces the test cost, but also significantly improves the integrated detection capability and automation level of the system. More importantly, the system successfully realizes seamless switching between whole machine testing and interface testing, which not only further improves the degree of automation of the test, but also ensures a significant improvement in test efficiency, while effectively controlling the test cost.

[0064] Specifically, the control module in the test equipment controls the communication between the switching control module and the terminal interface to be tested, and between the switching control module and the module to be tested, while disconnecting the communication between the interface of the module to be tested, thereby realizing the sequential connection of the terminal interface to be tested, the switching control module and the module to be tested (plugged into the whole machine to be tested), so as to facilitate the subsequent test equipment to carry out terminal whole machine testing.

[0065] Step S21: the testing device sends a whole machine testing plan to the whole machine to be tested.

[0066] Among them, the whole machine test plan includes all the test steps and parameters to be executed.

[0068] Furthermore, Figure 4 A test method of a terminal test system is shown, which is used to perform a module interface test on a whole device to be tested, and specifically includes:

[0069] Step S30: The testing device switches the interface of the module to be tested to the virtual terminal.

[0070] Specifically, the control module in the test equipment disconnects the communication between the control transfer module and the terminal interface under test, and the virtual module, while connecting the communication with the interface of the module under test, thereby realizing the connection between the interface of the module under test and the virtual terminal, making it easier for subsequent test equipment to carry out module interface testing.

[0071] Step S31: the test device controls the virtual terminal to identify the type of the module to be tested.

[0072] Step S32: The test device sends the test case to the virtual terminal.

[0073] Specifically, the test device sends a corresponding test case to the virtual terminal according to the identified type of the module to be tested.

[0074] Step S33: the virtual terminal tests the module to be tested according to the test case, and sends the test progress and results to the test device.

[0075] Specifically, the virtual terminal tests the module to be tested through the module to be tested interface according to the received test case, and feeds back the test progress and results to the test device in real time.

[0076] Step S34: the testing device summarizes the test results.
