[0034] In order to make the above-mentioned purposes, features and beneficial effects of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] It should be noted that the terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit this specification. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. In addition, the "plurality" appearing in the embodiments of the present application refers to two or more.

[0036] The use of dual-mode communication modules can achieve high-speed and reliable data transmission in power systems. For example, the HPLC-HRF dual-mode communication module combines carrier and wireless communication technologies. The working principles and processes are as follows:

[0037] (1) Data acquisition: Collect the data to be transmitted from the power system and process the collected data.

[0038] (2) Carrier communication: The processed data is transmitted to each node in the power system through a carrier signal. Carrier communication uses the power lines in the power system as the transmission medium to transmit data in the form of a carrier signal. Carrier communication has a high speed and stability.

[0039] (3) Wireless communication: In some cases where longer distance transmission is required, data is converted into high-frequency wireless signals and transmitted wirelessly through antennas. Wireless communication has a wider coverage range and can achieve long-distance communication.

[0040] (4) Data analysis: Analyze the received data, restore it to the original information, and perform corresponding processing or feedback.

[0041] In order to ensure the quality of communication, it is necessary to perform performance testing on the dual-mode communication module. In view of the problem that the existing test results in a laboratory environment cannot accurately reflect the real data in the actual operating environment, the embodiment of the present application provides a dual-mode communication module testing device and method, which tests the dual-mode communication module to be tested in the actual operating environment to obtain accurate test results that can reflect the actual operating environment.

[0042] like Figure 1 , which is a structural diagram of a dual-mode communication module testing device provided in an embodiment of the present application.

[0043] The dual-mode communication module testing device 100 is used to test the dual-mode communication module in the actual operating environment, for example, it can test the dual-mode communication module 1 and the dual-mode communication module 2 in the communication network, and the communication network can be a power system communication network or other system communication network, which is not limited to this embodiment of the present application.

[0044] In some embodiments, the communication network may include, for example: a carrier communication network, a wireless communication network, etc.

[0045] The test of the dual-mode communication module may include a performance test, and there may be multiple parameters that need to be tested, which are not limited in the embodiments of the present application.

[0046] Reference Figure 1 The dual-mode communication module testing device 100 includes: a control module 101, and a signal sending module 102 and a signal receiving module 103 respectively coupled to the control module 101; the signal sending module 102 and the signal receiving module 103 are also coupled to the communication network where the dual-mode communication module to be tested is located. Wherein:

[0047] The control module 101 is used to send a test command for the dual-mode communication module to be tested;

[0048] The signal sending module 102 is used to convert the test command into a communication signal, and send the communication signal to the dual-mode communication module to be tested through the communication network;

[0049] The signal receiving module 103 is used to receive a response signal from the dual-mode communication module to be tested through the communication network, and convert the response signal into a response command and send it to the control module 101;

[0050] Accordingly, the control module 101 may determine the test result of the dual-mode communication module to be tested according to the response command.

[0051] When testing the dual-mode communication module to be tested, a non-working time period of the application system (such as an electric power meter reading system) may be selected to complete the test of the dual-mode communication module to be tested.

[0052] In specific implementation, corresponding test software can be compiled according to test requirements, and the test software can be uploaded to the control module 101, and the control module 101 runs the test software to complete the test.

[0053] It should be noted that the dual-mode communication module to be tested can complete the reception and response of test data through a corresponding communication method according to the data format defined in the dual-mode technical specification. The communication method may include, but is not limited to, any one or more of the following: carrier communication, wireless communication, etc. Accordingly, the conversion of the test command by the signal sending module 102 can be converted accordingly according to the test needs, such as converting it into a carrier signal, or a wireless signal, etc.

[0054] The test of the dual-mode communication module to be tested can be determined according to the content to be tested, for example, simulating the slave node to send network conflict messages and event reporting messages to the master node; for another example, simulating the master node to read the slave node data, etc.

[0055] In some tests, sending a test command requires the currently running communication network parameters. Taking the power meter reading system as an example, the communication network parameters may include, but are not limited to: network ID, TEI (Terminal Equipment Identifier) ​​of the target node, network reference clock, etc. Otherwise, the sent test command may be invalid. To this end, in some embodiments, the signal receiving module 103 is also used to listen to the communication network parameters currently running in the communication network, and send the communication network parameters to the control module 101. Accordingly, the control module 101 determines the test command to be sent based on the communication network parameters. For example, to simulate the master node reading the slave node data, the reading command sent needs to use the network ID and the TEI of the target node.

[0056] It should be noted that what kind of test command the control module 101 sends is determined by the specific test content and has nothing to do with the monitored communication network parameters.

[0057] During each test, the control module 101 can initialize the signal sending module 102 and the signal receiving module 103 through the control port, for example, clear the cache, and if necessary, set the CRC check to automatically fill in, set the TEI list for automatic reply ACK, etc. Further, the control port can also be used to set communication parameters for the signal sending module 102 and the signal receiving module 103, such as the communication frequency band of the high-speed carrier, the communication frequency of the high-speed wireless communication, the communication address of the dual-mode communication module to be tested, and other parameters.

[0058] By using the dual-mode communication module testing device provided in the embodiment of the present application, online detection can be performed on the running equipment, and operation and maintenance of the equipment can be performed or problems arising during the operation of the equipment can be checked, which greatly reduces the testing cost, improves the testing efficiency, shortens the product development time, and reduces the maintenance workload.

[0059] Accordingly, the present application also provides a dual-mode communication module testing method, such as Figure 2 The figure shows a flow chart of a dual-mode communication module testing method provided in an embodiment of the present application.

[0060] In step 201, a test command is sent for a dual-mode communication module to be tested, where the dual-mode communication module to be tested is located in a communication network under an actual operating environment.

[0061] For example, the test command is converted into a high-speed carrier signal; or the test command is converted into a high-speed wireless signal, etc., which can be specifically determined according to the communication mode currently running in the dual-mode communication module to be tested.

[0062] In step 202, the test command is converted into a communication signal, and the communication signal is sent to the dual-mode communication module to be tested through the communication network.

[0063] In step 203, a response signal of the dual-mode communication module to be tested is received through the communication network, and the response signal is converted into a response command.

[0064] The response signal and the communication signal are signals of the same type, for example, both are carrier signals, or both are wireless signals.

[0065] In step 204, a test result of the dual-mode communication module to be tested is determined according to the response command.

[0066] In a non-limiting embodiment, the dual-mode communication module testing method may further include the following steps: monitoring the communication network parameters currently running in the communication network. Accordingly, in the above step 201, the test command to be sent may be determined according to the communication network parameters.

[0067] It should be noted that in the specific implementation, the Figure 1 The test process shown is cut, combined or repeated in a loop to complete all test contents. For example, to test the carrier signal strength or wireless signal strength in the actual operating environment, it is only necessary to receive signal data without sending test commands; for another example, to test the meter reading function of the main node in the power meter reading system, it is necessary to repeat the above process multiple times, that is, multiple communication interactions are required.

[0068] The dual-mode communication module testing method provided in the embodiment of the present application can complete the testing of the dual-mode communication module in the actual operating environment during the non-working time period of the application system, thereby realizing the testing of the dual-mode communication unit in the actual operating environment, improving the accuracy of the test, and providing more accurate test results for product testing.

[0069] In the electric power meter reading system, the dual-mode communication module converts the data from the upstream node (such as the concentrator) into HPLC or HRF signals and transmits them to the meter end. After receiving the signal, the communication unit at the meter end converts it into data that the meter can recognize, and transmits the meter's response data back to the upstream node through the dual-mode communication module.

[0070] When testing a specific dual-mode communication module in an electric power meter reading system, the above process can be simulated, and the testing device sends a communication signal containing a test command to the dual-mode communication module, and the dual-mode communication module transmits the corresponding communication signal to the electric meter, and then transmits the response data of the electric meter to the testing device. The testing device determines the test result based on the response data, and the test result can more accurately reflect the performance of the dual-mode communication module in the actual operating environment.
