The energy meter management module is the core of the meter, and testing its functional integrity, real-time performance, and robustness is crucial.

[0003] In existing technology, testing typically involves combining a real metering module with host computer software. However, because the metering module in the test environment is a real hardware circuit, including information collection and metering modules, the response time is relatively long. Furthermore, the test time for each test item in the meter management module must be set according to the meter's actual operating cycle. Furthermore, when the meter management module handles multiple tasks simultaneously, it can cause timing errors due to multiple simultaneous instructions sent and received from the metering module. This ultimately leads to longer test cycles and higher testing costs for the meter management module. Summary of the Invention

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0027] Currently, manufacturers design new smart energy meters based on technical specifications, featuring hardware platformization and software application. The energy meter management module is the core of the energy meter, and testing its functional integrity, real-time performance, and robustness is crucial. Existing testing technologies typically employ a real metering module coupled with host computer software for testing. However, because the metering module in the test environment is a real hardware circuit, including information collection and metering modules, the response time is relatively long. Furthermore, the test time for each test item in the energy meter management module needs to be set according to the actual operating cycle of the energy meter. Furthermore, when the energy meter management module handles multiple tasks simultaneously, it will issue and receive metering module instructions multiple times, causing timing errors. This ultimately results in a longer test cycle for the energy meter management module and higher testing costs.

[0028] In order to solve the above problems, in one embodiment, a method for testing an electric energy meter management module is provided. Figure 1 The test setup shown is Figure 1 As shown, the test device is used to test the electric energy meter management module with an operating system, and the test device includes: a host computer 1, an analog metering module 2, and a management module interface 3 for connecting to the electric energy meter management module 4, wherein the electric energy meter management module is an electric energy meter management module with an operating system. Figure 2 A flow chart of a method for testing an energy meter management module is given, as shown in Figure 2 As shown, the method is applied to the above-mentioned test device as an example for description, and includes the following steps:

[0029] 101. The host computer determines a test case in response to a test case selection request, and sends an analog measurement value corresponding to the test case to the analog measurement module.

[0030] Wherein, at least one test case is pre-stored in the host computer, and each of the test cases corresponds to a simulated measurement value, which is a simulated test electrical signal required for testing the electric energy meter management module.

[0031] Specifically, the electric energy meter management module to be tested is connected to the management module interface, and when the device is powered on, the test case is selected based on the host computer. The test case refers to the description of the test task for a specific product, reflecting the test plan, method, technology and strategy, and corresponds to the configuration parameters required for the test, such as the meter address, communication baud rate, serial port and other information for executing the test plan. Each test case corresponds to the pre-set analog measurement value required for the test case, and the analog measurement value and the corresponding test case are stored in the host computer. At the same time, the communication parameters required for the test, including the meter address, baud rate, time, data identifier, data format, etc., can be input based on the host computer to realize data interaction between devices. Subsequently, the host computer can send the test case for the test and the analog measurement value corresponding to the test case to the analog metering module for identification and storage by the analog metering module.

[0032] 102. The analog metering module receives and stores the analog metering value, and sends a confirmation message to the host computer.

[0033] Specifically, after receiving the simulated metering value from the host computer, the analog metering module will store the simulated metering value locally and set test-related data such as real-time metering data or minute-freeze data based on the simulated metering value. It will then send a confirmation message to the host computer, where the confirmation message is the storage result of the simulated metering value in the analog metering module. Furthermore, during the test, the analog metering module can generate the test electrical signal required for the test based on the simulated metering value. This test electrical signal simulates the test electrical signal generated by the real metering module during operation as metering data, which is then read by the energy meter management module.

[0034] 103. The host computer sends a test execution command to the electric energy meter management module based on the confirmation information.

[0035] Specifically, the host computer can receive confirmation information from the analog metering module and, based on the confirmation information regarding the storage of the analog metering values in the analog metering module, determine whether each analog metering value deviates from the original analog metering value in the host computer. If a deviation is detected, a warning message can be issued to prompt the tester to take action or the analog metering value can be sent to the analog metering module again. If no deviation is detected, a test execution command is sent to the energy meter management module to instruct the energy meter management module to start operation.

[0036] 104. The electric energy meter management module receives a test electrical signal corresponding to the analog metering value from the analog metering module through the management module interface based on the test execution command, generates test data based on the test electrical signal, and sends the test data to the host computer through the management module interface.

[0037] The test electrical signal is an electrical signal emitted by the analog metering module during operation under a real hardware environment, simulated by the analog metering module based on the simulated metering value. The energy meter management module receives the electrical signal and generates relevant reading information and control information. Furthermore, the analog metering module can simulate the electrical signals emitted by the metering module under different operating conditions in a single test process based on the simulated metering value, thereby obtaining test results for the energy meter management module under different simulated environments in a single test process.

[0038] Specifically, the electricity meter management module receives a test execution command, confirms the start of the test, receives a test electrical signal corresponding to the analog metering value from the analog metering module through the management module interface, simulates the management of the real metering module, generates reading information and control information, generates test data, and sends the test data to the host computer.

[0039] 105. The host computer generates a test result of the electric energy meter management module based on the received test data. The test data may include parameter types and functions as shown in Table 1:

[0040]

[0041]

[0042] Table 1

[0043] Specifically, the host computer can make judgments on the parameter values in the test data, such as phase voltage, total reactive power and other parameters, and compare the parameter values with the standard parameter values corresponding to the test case to obtain the test results of the electricity meter management module.

[0044] As an example, when performing a serial peripheral interface (SPI) read / write test and a communication response efficiency test between the management module and the analog metering module, the corresponding test case is selected in the host computer, and the analog metering module is written with analog metering values corresponding to the SPI interface read / write test and the communication response efficiency test, including (current) forward active total energy, (current) reverse active total energy, and minute frozen data. The management module reads the metering real-time data and minute frozen data, so that the analog metering module generates the corresponding test environment. After confirming that the information is correct, the host computer sends a trial execution command to instruct the energy meter management module to start executing the test. The energy meter management module reads the test data based on the analog metering module and sends the test data to the host computer. The host computer records the data read by the energy meter management module and compares it with the data corresponding to the analog metering value written to the analog metering module to test the energy meter management module software processing capability, including the start and completion time of each reading, the time taken and response time of each operation of the SPI interface, etc. The test can be repeated multiple times and the test results can be recorded respectively.

[0045] In addition, invalid data can be written to the analog metering module, including data with correct content but incorrect format, data with incorrect frame format, real-time data with incorrect frame content, minute-frozen data, and other data. At the beginning of the test, the host computer records the data read by the energy meter management module to test whether the energy meter management module responds to the negative frame according to the specification. Subsequently, normal data is written to the analog metering module to determine whether the data read by the energy meter management module is normal, thereby testing the energy meter management module software processing capabilities.

[0046] The electric energy meter management module testing method provided in this embodiment can generate a corresponding simulated test environment for the simulated metering module based on the user's test selection, so that the user does not have to be restricted by the actual operation cycle of the electric energy meter under the real metering module when performing the test items of the electric energy meter management module, and can shorten the response time. At the same time, by optimizing the test process of the electric energy meter management module, the problem of timing disorder can also be avoided, thereby effectively reducing the test cycle and reducing the test cost.

[0047] In one embodiment, the structure of the analog metering module is given, such as Figure 3 As shown, the analog metrology module includes a central processing unit (CPU) 31 and a random access memory (RAM) 32. The CPU 31 has a performance no less than that of a Cortex-M4 architecture and a main frequency no less than 60 MHz. The RAM 32 has a capacity greater than or equal to 1 megabyte. The large-capacity RAM within the analog metrology module allows for rapid reading and writing of test information, while the high-performance CPU enables rapid scheduling of information.

[0048] Furthermore, the analog metering module receives and stores the analog metering value and sends a confirmation message to the host computer, including: the central processing unit stores the analog metering value in the random access memory and sends the storage result of the analog metering value to the host computer as confirmation information. Furthermore, step 103 includes: first, the host computer determines whether the analog metering value satisfies a preset comparison relationship with the test case based on the received analog metering value. The comparison relationship is a correspondence between the test case and the analog metering value required to execute the test case. Each test case has a corresponding analog metering value that satisfies the corresponding relationship. Specifically, each test case corresponds to a corresponding analog metering value, and the two can be stored in the host computer in the form of a comparison table. When the host computer sends the analog metering value corresponding to each test case to the analog metering module, the analog metering module stores the analog metering value and returns the storage result to the host computer as confirmation information. Based on the received confirmation information including the analog metering value stored by the analog metering module, the host computer determines whether the analog metering value in the confirmation information satisfies the comparison relationship with the test case. If the analog metering value and the test case satisfy the aforementioned correlation, the host computer sends a test execution command to the electricity meter management module. Specifically, if the analog metering value and the test case satisfy the aforementioned correlation, the analog metering value stored by the analog metering module is determined to be correct, and the next test step can be performed. In the embodiments of the present application, based on confirming the analog metering value stored by the analog metering module, it is possible to ensure that the analog metering module generates a correct test environment during subsequent tests, improving the accuracy of the test work.

[0049] In one embodiment, the electric energy meter management module receives a test electrical signal corresponding to the analog metering value from the analog metering module through the management module interface based on the test execution command, including: first, the electric energy meter management module issues a read information command in response to the test execution command, and sends the read information command to the analog metering module. The read information command can be a signal for controlling the analog metering module to generate a simulated test environment based on the analog metering value. Specifically, after receiving the test execution command, the electric energy meter management module can determine whether it is in a ready state. If the electric energy meter management module is in a ready state for testing, it can issue a read information command to the analog metering module. If the electric energy meter management module is not in a ready state, it can issue an alarm message to enable the tester to handle it. After issuing the read information command, the electric energy meter management module can enter a standby state and prepare to read the test electrical signal issued by the analog metering module. Then, in response to the read information command, the analog metering module retrieves the analog metering value from the random access memory, generates a test electrical signal corresponding to the analog metering value, and sends the test electrical signal to the electric energy meter management module. Finally, the electric energy meter management module receives the test electrical signal. In an embodiment of the present application, based on the electric energy meter management module in a ready state, an instruction to generate a test electrical signal is sent to the analog metering module to ensure that when the analog metering module is running, the electric energy meter management module can normally receive the test signal, ensure that the electric energy meter management module can fully perform the management work of the analog metering module during the test cycle, and ensure the effectiveness of the test work.

[0050] In one embodiment, the test results include normal results and abnormal results. If the values of various parameters in the test results are within a threshold range set for the parameter values, the test result is determined to be normal. If the values of various parameters in the test results are not within the threshold range set for the parameter values, the test result is determined to be abnormal. Specifically, if the test result is normal, it indicates that the electric energy meter management module is able to perform management functions normally and can be used normally. If the test result is abnormal, it indicates that the electric energy meter management module is not able to perform management functions normally and requires further testing. Furthermore, the testing device also includes an indicator light, wherein the indicator light is connected to the host computer. Furthermore, the method further includes: if the test result is normal, the host computer controlling the indicator light to display in a preset first state. The first state may be that the indicator light is constantly on. If the test result is abnormal, the host computer controlling the indicator light to display in a preset second state. The second state may be that the indicator light flashes at a specific frequency, indicating to the tester that the electric energy meter management module is not able to perform management functions normally and requires further testing. Furthermore, the test status can also be displayed based on the indicator light. Specifically, if the device is in a normal test state, the host computer controls the indicator light to display in a preset third state, such as displaying with a light of a specific color; if the device is in an abnormal test state, the host computer controls the indicator light to display in a preset fourth state, such as displaying with a light of a specific color different from the third state, so as to intuitively display the operating status of the device. In an embodiment of the present application, the test status of this test and whether the test result is normal can be displayed to the tester based on the different states of the indicator light, which can more intuitively display the test process and results.

[0051] The electric energy meter management module testing method provided in this embodiment can generate a corresponding simulated test environment for the simulated metering module based on the user's test selection, so that the user does not have to be restricted by the actual operation cycle of the electric energy meter under the real metering module when performing the test items of the electric energy meter management module, and can shorten the response time. Furthermore, by setting a status indicator light, the test status and test results are displayed to the tester, which can more intuitively display the test process and results. At the same time, by setting an indicator signal for instructing each unit to start executing the relevant steps, the test process and results are intuitively displayed. By optimizing the test process of the electric energy meter management module, the problem of timing disorder can also be avoided, thereby effectively reducing the test cycle and reducing the test cost.

[0052] Further, as Figure 2As a specific implementation of the method shown, this embodiment provides an electric energy meter management module testing device, which includes: the device includes a host computer, an analog metering module, and a management module interface for connecting to the electric energy meter management module.

[0053] The host computer is configured to determine a test case in response to a test case selection request, and send a simulated measurement value corresponding to the test case to the simulated measurement module, wherein at least one test case is pre-stored in the host computer, and each test case corresponds to a simulated measurement value;

[0054] The analog measurement module is used to receive and store the analog measurement value and send a confirmation message to the host computer;

[0055] The host computer is also used to send a test execution command to the electric energy meter management module based on the confirmation information, so that the electric energy meter management module receives a test electrical signal corresponding to the analog metering value from the analog metering module through the management module interface based on the test execution command, generates test data based on the test electrical signal, and sends the test data to the host computer through the management module interface.

[0056] The host computer is further configured to generate a test result of the electric energy meter management module based on the received test data.

[0057] In one embodiment, the first interface of the host computer is connected to the first interface of the management module interface via a first universal asynchronous receiver / transmitter bus, the second interface of the host computer is connected to the first interface of the analog metering module via a second universal asynchronous receiver / transmitter bus, and the second interface of the analog metering module is connected to the second interface of the management module interface via a third universal asynchronous receiver / transmitter bus or a serial peripheral interface bus. Wherein, the host computer and the electric energy meter management module adopt an asynchronous receiver / transmitter bus (UART) interface communication to realize the issuance, execution and return of test tasks, the host computer and the analog metering module adopt a UART interface communication to realize the host computer's setting of data in the random access memory, and the electric energy meter management module and the analog metering module adopt a UART or serial peripheral interface bus communication to realize the execution of the test tasks issued by the host computer software by the electric energy meter management module. Communication based on UART interface communication can realize full-duplex transmission and reception, improve data transmission efficiency, and effectively reduce the occurrence of timing disorder. In addition, when the second interface of the analog metering module is connected to the second interface of the management module interface through a serial peripheral interface bus, the device divides the analog metering module into two communication channels, communicating with the host computer and the electric energy meter management module respectively, solving the timing disorder problem caused by the simultaneous data setting and execution test of the analog metering module during communication between the electric energy meter management module and the analog metering module, and can accurately test whether there is a timing problem in the serial peripheral interface bus of the electric energy meter management module.

[0058] In one embodiment, Figure 4 As shown, the test device includes a device housing 41 having multiple sides, wherein the host computer and the analog metering module are disposed within the device housing 41, and the management module interface 42 is disposed on one of the sides of the device housing 41 for connecting to the electric energy meter management module. The test device also includes an indicator light 43 disposed on one of the sides of the device housing 41, wherein the indicator light 43 is connected to the host computer, and the number of indicator lights 43 can be one or more. Furthermore, a host computer touch screen display 46 can be disposed on one side of the device housing 41 for configuring the host computer and reading host computer-related information to track and control the test work.

[0059] In one embodiment, the device further includes a Universal Serial Bus (USB) interface, wherein the USB interface is connected to the host computer and is used to connect to an external communication terminal. This facilitates importing control software into the host computer without a network. Further, Figure 5As shown, the electric energy meter management module test device also includes a DC power supply module 5 and an AC power supply module 6, wherein the DC power supply module 5 is used to power the analog metering module 2 and the electric energy meter management module 4, and the AC power supply module 6 is used to power the host computer 1. Specifically, the DC power supply module 5 can provide 5V and 15V power supplies to power the analog metering module 2 and the electric energy meter management module 4, respectively. The AC power supply module 6 can provide 220V power supply to power the host computer. Based on the DC power supply module and AC power supply module in the electric energy meter management module test device, the components with different power supply requirements are respectively powered, thereby improving the stability of the power supply of the device.

[0060] In one embodiment, the analog metrology module includes a central processing unit (CPU) and a random access memory (RAM). The CPU's performance is comparable to that of a Cortex-M4 architecture, with a clock speed of at least 60 MHz. The RAM's capacity is greater than or equal to 1 megabyte. The large-capacity RAM within the analog metrology module allows for rapid reading and writing of test information, while the high-performance CPU enables rapid scheduling of this information.

[0061] Furthermore, the analog metering module can also be configured to receive and store the analog metering value and send a confirmation message to the host computer, including: the central processing unit storing the analog metering value in the random access memory and sending the stored analog metering value result as confirmation message to the host computer. Furthermore, the host computer can also be configured to send a test execution command to the electric energy meter management module based on the confirmation message, including: first, the host computer, based on the received analog metering value, determines whether the analog metering value satisfies a preset comparison relationship with the test case. The comparison relationship is a correspondence between the test case and the analog metering value required to execute the test case. Each test case has a corresponding analog metering value. Specifically, each test case corresponds to a corresponding analog metering value, and the two can be stored in the host computer in the form of a comparison table. When the host computer sends the analog metering value corresponding to each test case to the analog metering module, the analog metering module stores the analog metering value and returns the stored result as confirmation message to the host computer. Based on the received confirmation information including the analog metering value stored by the analog metering module, the host computer determines whether the analog metering value in the confirmation information satisfies the control relationship with the test case. If the analog metering value and the test case satisfy the control relationship, the host computer sends a test execution command to the electric energy meter management module. Specifically, when the analog metering value and the test case satisfy the control relationship, it is determined that the analog metering value stored in the analog metering module is correct, and the next test can be carried out. In an embodiment of the present application, based on the confirmation of the analog metering value stored in the analog metering module, it can be ensured that the analog metering module can generate a correct test environment in subsequent tests to improve the accuracy of the test work.

[0062] In one embodiment, the electric energy meter management module can also be used to receive a test electrical signal corresponding to the analog metering value from the analog metering module via the management module interface based on the test execution command, including: first, the electric energy meter management module issues a read information command in response to the test execution command, and sends the read information command to the analog metering module. The read information command can be a signal that controls the analog metering module to generate a simulated test environment based on the analog metering value. Specifically, after receiving the test execution command, the electric energy meter management module can determine whether it is in a ready state. If the electric energy meter management module is in a ready state for testing, it can issue a read information command to the analog metering module. If the electric energy meter management module is not in a ready state, it can issue an alarm message to enable the tester to handle it. After issuing the read information command, the electric energy meter management module can enter a standby state and prepare to read the test electrical signal issued by the analog metering module. Then, in response to the read information command, the analog metering module retrieves the analog metering value from the random access memory, generates a test electrical signal corresponding to the analog metering value, and sends the test electrical signal to the electric energy meter management module. Finally, the electric energy meter management module receives the test electrical signal. In an embodiment of the present application, based on the electric energy meter management module in a ready state, an instruction to generate a test electrical signal is sent to the analog metering module to ensure that when the analog metering module is running, the electric energy meter management module can normally receive the test signal, ensure that the electric energy meter management module can fully perform the management work of the analog metering module during the test cycle, and ensure the effectiveness of the test work.

[0063] In one embodiment, the test results generated by the host computer include normal results and abnormal results. If the values of various parameters in the test results are within a threshold range set for the parameter values, the test result is determined to be normal. If the values of various parameters in the test results are not within the threshold range set for the parameter values, the test result is determined to be abnormal. Specifically, if the test result is normal, it indicates that the electricity meter management module is able to perform management functions normally and can be used normally. If the test result is abnormal, it indicates that the electricity meter management module is not able to perform management functions normally and requires further testing. Furthermore, the testing device also includes an indicator light, which is connected to the host computer. Furthermore, the host computer is further configured to: if the test result is normal, control the indicator light to display in a preset first state. The first state may be that the indicator light is constantly on. If the test result is abnormal, the host computer controls the indicator light to display in a preset second state. The second state may be that the indicator light flashes at a specific frequency, indicating to the tester that the electricity meter management module is not able to perform management functions normally and requires further testing. Furthermore, the test status can also be displayed based on the indicator light. Specifically, if the device is in a normal test state, the host computer controls the indicator light to display in a preset third state, such as displaying with a light of a specific color; if the device is in an abnormal test state, the host computer controls the indicator light to display in a preset fourth state, such as displaying with a light of a specific color different from the third state, so as to intuitively display the operating status of the device. In an embodiment of the present application, the test status of this test and whether the test result is normal can be displayed to the tester based on the different states of the indicator light, which can more intuitively display the test process and results.
