[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following describes a detection device and a detection system for a communication module according to an embodiment of the present invention with reference to the accompanying drawings.

[0032] Figure 1 FIG. 1 is a schematic diagram of a detection device for a communication module according to an embodiment of the present invention. Figure 1 As shown, the detection device of the communication module includes: at least two shielding boxes 10 , a signal control unit 20 , a test unit 30 and a control unit 40 .

[0033] Among them, at least two shielding boxes 10 are connected in series, one shielding box 10 is suitable for placing the acquisition terminal 11, and the remaining shielding boxes are suitable for placing the communication modules 200 to be tested, and the acquisition terminal 11 is configured to be networked with each communication module 200 to be tested, and to collect data for each communication module 200 to be tested; the signal control unit 20 is connected to each shielding box 10, and is configured to control the communication signal input to the remaining shielding boxes to adjust the station area topology level and topology path of the communication module 200 to be tested; the test unit 30 is connected to each shielding box 10, and is configured to test the communication performance between the acquisition terminal 11 and each communication module 200 to be tested; the control unit 40 is respectively connected to the acquisition terminal 11, the signal control unit 20 and the communication connection, and is configured to send test cases to the signal control unit 20, so that the signal control unit 20 tests all communication modules 200 to be tested according to the test cases, and generates test results according to the data collected by the acquisition terminal 11 and the performance test results of the test unit 30.

[0034] Specifically, the shielding box 10 is suitable for placing the acquisition terminal tooling, the virtual electric energy meter tooling, and the real terminal and electric energy meter, etc. The shielding box 10 can block external radio wave interference and absorb the leakage of radio frequency signals in the box, thereby providing a controlled test environment. Each of the remaining shielding boxes is suitable for placing a first-level communication module 200 to be tested, thereby realizing a multi-level topology. The signal control unit 20 is connected to the remaining shielding boxes through a radio frequency line to provide a communication signal (such as a carrier signal and a micro-power wireless signal) to the communication module 200 to be tested. By adjusting the amplitude of the communication signal input to the remaining shielding boxes, a tree topology or a star topology is constructed, and the station area topology level and topological path of the communication module 200 to be tested are adjusted. The test unit 30 tests the communication performance, protocol consistency, etc. between the acquisition terminal 11 and the communication module 200 to be tested. The control unit 40 can be a server for running a full-link simulation test system, and includes a simulation master station. Running the full-link simulation test system is used to realize remote control and management of the detection device. By configuring different test cases to control the signal control unit 20, the signal control unit 20 can simulate different communication environments in different stations, and then the control unit 40 generates test results of all communication modules 200 to be tested according to the data collected by the acquisition terminal 11 and the performance test results of the test unit 30. When there is a problem with the communication link between the control unit 40 and the acquisition terminal 11, the collected data cannot be reported to the control unit 40 normally; when there is a problem with the communication link between the acquisition terminal 11 and the communication module 200 to be tested, the acquisition terminal 11 cannot normally collect the data of the communication module 200 to be tested; when there is a problem with the communication link between the communication modules 200 to be tested, the data collected by the acquisition terminal 11 can reflect that there is a problem with the communication module 200 to be tested. Therefore, the control unit 40 can detect the communication of the entire link.

[0035] In an optional embodiment, the control unit 40 also has the function of simulating a metering automation system, including common metering automation system functions such as equipment online, data collection at the collection terminal 11, parameter reading control at the collection terminal 11, file management, scheduled task data collection and display, and data query, so as to simulate the operation scenario of the equipment in the metering automation system.

[0036] In some embodiments, the communication module 200 to be tested includes at least one of a single-phase STA and a three-phase STA.

[0037] It is understandable that the communication module 200 to be tested is composed of a single-phase STA, a three-phase STA, or a single-phase STA and a three-phase STA. Therefore, the detection device of this embodiment has high flexibility and adaptability and can handle different types of communication modules.

[0038] It should be noted that the detection device of this embodiment not only supports full-link communication detection, but also supports limit capability detection, in-depth application detection, interoperability detection, physical layer consistency testing, specific fault scenario testing, standard collection task testing, etc.

[0039] In the above embodiment, the communication link between the control unit and the acquisition terminal, the communication link between the acquisition terminal and the communication module to be tested, and the communication link between the multi-level communication module topologies to be tested are detected, thereby realizing full-link communication detection and improving the detection effect.

[0040] In some embodiments, Figure 2 As shown, a local communication module 12 is provided on the acquisition terminal 11 , and the local communication module 12 is communicatively connected with each communication module 200 to be tested.

[0041] Specifically, the acquisition terminal 11 is provided with a local communication module 12, and the local communication module 12 can perform power line broadband carrier communication or micro-power wireless communication with the communication modules 200 to be tested in the remaining shielding boxes. Therefore, the acquisition terminal 11 can be networked with each communication module 200 to be tested and collect data for each communication module 200 to be tested.

[0042] Optionally, the local communication module 12 is a CCO.

[0043] It is understandable that, because the communication module 200 to be tested includes at least one of a single-phase STA and a three-phase STA, in order to successfully form a network with the communication module 200 to be tested, the local communication module 12 is a CCO.

[0044] In some embodiments, Figure 2As shown, the acquisition terminal 11 is also provided with a remote communication module 13 , and the remote communication module 13 is communicatively connected with the control unit 40 .

[0045] Specifically, the acquisition terminal 11 is also provided with a remote communication module 13 for communicating with the control unit 40 , and the remote communication module 13 performs wireless communication with the simulation master station through a network.

[0046] Furthermore, in some embodiments, the remote communication module 13 is a 4G (fourth generation mobile communication technology) communication module.

[0047] That is, the acquisition terminal 11 and the control terminal element perform 4G network communication through the 4G communication module. It should be noted that the remote communication module 13 is not limited to the 4G communication module, but can also be other communication modules. The 4G communication module is only exemplary and is not a limitation to this application.

[0048] In some embodiments, the acquisition terminal 11 is connected to the control unit 40 via Ethernet.

[0049] It is understandable that the acquisition terminal 11 may not be provided with the remote communication module 13, but may be directly connected to the control unit 40 via a network cable, thereby communicating with the control terminal element via Ethernet.

[0050] In some embodiments, the control unit 40 is also configured to monitor the reported messages of the acquisition terminal 11, the first communication messages between the acquisition terminal 11 and the remote communication module 13, the second communication messages between the acquisition terminal 11 and the local communication module 12, and the third communication messages between the local communication module 12 and each communication module 200 to be tested, and perform fault location and fault analysis based on the reported messages, the first communication messages, the second communication messages, the third communication messages and the test results.

[0051] Specifically, the control unit 40 can not only perform communication detection on the entire link, but also monitor and analyze different protocol messages of the entire link, and locate the fault according to the messages of each link. The control unit 40 monitors the reported message, the first communication message, the second communication message, the third communication message, and the fourth communication message between the communication module 200 to be tested and the meter node, and parses and displays the monitored various messages (such as Southern Power Grid metering automation, broadband protocol, 645 protocol) according to the preset parsing specification, stores the parsed messages at the first level, and then can use a variety of screening methods to find historical messages. The control unit 40 locates the fault through the test results and the messages of each link on the entire link, and analyzes the cause of the fault based on the result data in the test process, the interactive messages of each link of the entire link, the communication channel parameters of each link, the internal task processing data of the equipment and the fault library, and maintains the fault library using the fault analysis results.

[0052] In the above embodiment, the control unit can monitor and analyze the communication messages of the entire link, and then use the monitored communication messages and the test results obtained to perform fault location and fault analysis. Therefore, the detection device of this embodiment can not only detect the communication module, but also perform fault location and fault analysis, thereby realizing more functions.

[0053] In some embodiments, Figure 3 As shown, the signal control unit 20 includes: a carrier signal control module 21, a radio frequency signal control module 22 and at least one programmable attenuator 23, wherein the carrier signal control module 21 is configured to provide a power line broadband carrier signal; the radio frequency signal control module 22 is configured to provide a micro-power wireless signal; each programmable attenuator 23 is arranged between two adjacent shielding boxes 10, and is respectively connected to the carrier signal control module 21 and the radio frequency signal control module 22, each programmable attenuator 23 is configured to attenuate the power line broadband carrier signal and the micro-power wireless signal according to the test case, and provide the attenuated power line broadband carrier signal and the micro-power wireless signal to the corresponding communication module 200 to be tested, so as to adjust the station area topology of the corresponding communication module 200 to be tested.

[0054] Specifically, the control unit 40 controls the carrier signal control module 21 and the radio frequency signal control module 22 to respectively provide the carrier signal and the micro-power wireless signal to each programmable attenuator 23. The programmable attenuator 23 is arranged between two adjacent shielding boxes 10, and the control unit 40 controls the attenuation value of the carrier signal and the micro-power wireless signal by the programmable attenuator 23, and then outputs the attenuated signal, thereby simulating the multi-level topology in the real application scenario, such as the tree topology and the star topology.

[0055] In the above embodiment, the signal control unit includes a carrier signal control module, a radio frequency signal control module and a programmable attenuator, which realizes precise control of the power line broadband carrier signal and the micro-power wireless signal, so that the test device can simulate the communication conditions in the real environment and conduct comprehensive testing and evaluation of the communication module to be tested. In addition, the substation topology can be adjusted by adjusting the signal attenuation, thereby evaluating the performance of the communication module under different conditions, thereby ensuring its reliability and stability in practical applications.

[0056] In some embodiments, Figure 4 As shown, the test unit 30 includes: a spectrum analyzer 31, which is respectively connected to each shielding box 10 and the control unit 40, and is configured to test the communication performance between the acquisition terminal 11 and each communication module 200 to be tested to generate a performance test result, and send the performance test result to the control unit 40.

[0057] Specifically, the spectrum analyzer 31 can measure and analyze the spectrum characteristics of the communication signal, including the frequency range, power distribution, modulation mode, etc. of the signal. During the test, the spectrum analyzer 31 receives the communication signal from the acquisition terminal 11 and the communication module 200 to be tested, and analyzes it in detail. By analyzing the spectrum characteristics of the signal, the spectrum analyzer 31 can evaluate the integrity, stability and reliability of the communication signal, thereby generating a performance test result, and then sending the performance test result to the control unit 40 so that the control unit 40 performs analysis based on the performance test result.

[0058] In some embodiments, Figure 4 As shown, the test unit 30 also includes a function generator 32, which is connected to the control unit 40 and is configured to inject a noise signal into the corresponding communication module 200 to be tested; the control unit 40 is also connected to the function generator 32, and the control unit 40 is configured to control the function generator 32 according to a pre-constructed simulation environment database to construct a test environment for the communication module 200 to be tested.

[0059] Specifically, the function generator 32 can generate various types of signals, including sine waves, square waves, pulse waves, etc., which can be used as noise signals. During the test, the function generator 32 injects a preset noise signal into the communication module 200 to be tested according to the instruction of the control unit 40. By injecting the noise signal, the interference and noise that may exist in the real communication environment can be simulated, so as to evaluate the anti-interference ability and stability of the communication module 200 to be tested in a complex environment. The simulation environment database can include a variety of typical environmental data such as urban stations, urban-rural combined stations, and rural stations. The control unit 40 can directly use the environmental data in the simulation environment database to construct the test environment of the communication module 200 to be tested.

[0060] In the above embodiment, the test unit further includes a function generator, which can simulate noise signals in a real environment according to the instructions of the control unit, so as to detect the anti-interference ability and stability of the communication module to be tested in a complex environment.

[0061] In some embodiments, the control unit 40 is further configured to generate test cases based on historical test data, the version of the acquisition terminal 11 and the version of the communication module 200 to be tested, generate a test report based on the test results and a preset report template, and store the test report.

[0062] Specifically, the control unit 40 can manage the supplier and version of each device in the detection device, and the control unit 40 manages the supplier, device version and program life cycle of the acquisition terminal 11, CCO, STA module and other devices, and can be associated with the test case based on the historical test data. Specifically, the historical test data includes problems that occur during the test process of different suppliers and different device versions. Therefore, a test case can be generated based on the historical test data, the version of the acquisition terminal 11 and the version of the communication module 200 to be tested.

[0063] Furthermore, the control unit 40 can not only generate test cases, but also manage test steps, test schemes, and test plans, and can freely combine various test cases to test various terminals, modules, and electric meters in various complex simulation field environments. For the test results, a test report can be generated according to a preset report template, and the historical test results and test reports can be stored.

[0064] In the above embodiment, the control unit can manage the versions of each device to generate test cases according to the versions of each device, generate test reports according to the test results, and store the test reports for subsequent reference.

[0065] In some embodiments, the control unit 40 is further configured to rate the application effect of each communication module 200 to be tested according to the acquisition success rate and event reporting success rate of the acquisition terminal 11 , the communication timeliness and networking compatibility of the test unit 30 .

[0066] It is understandable that when simulating a complex substation environment, the control unit 40 can also rate the application effect of each communication module 200 to be tested based on the reliability of the communication module 200 to be tested, the collection success rate and event reporting success rate of the terminal, the communication timeliness of the test unit 30, and the networking compatibility. The control unit 40 can then use the rating results to provide data support for guiding the on-site substation module assembly plan.

[0067] In some embodiments, Figure 5 As shown, the detection device also includes: a programmable power supply 50 and a switch 60, wherein the programmable power supply 50 is connected to each shielding box 10 to provide an isolated power supply to each shielding box 10; the programmable power supply 50, the signal control unit 20 and the test unit 30 are connected to the control unit 40 via the switch 60.

[0068] Specifically, the program-controlled power supply 50 is used to provide a standard isolated power supply, thereby deepening the functional test. The acquisition terminal 11, the program-controlled power supply 50, the spectrum analyzer 31, the function generator 32, the carrier signal control module 21 and the radio frequency signal control module 22 can all be connected to the switch 60 via a network cable, thereby communicating with the control unit 40 through the network.

[0069] Based on this, the control unit 40 can remotely control various types of tooling equipment in batches, such as controlling the programmable power supply 50, topology switching and noise injection, and can monitor the operating status of various types of tooling.

[0070] In an optional implementation, the control unit 40 can also manage the personnel accounts, role permissions, operation logs, etc. of the system. The control unit 40 provides a complete permission management, and operators of different levels have different functional modules and operation permissions. The control unit 40 also provides a complete log recording function, which records information such as system login, module use, data changes, terminal operations, etc., and can be queried and retrieved.

[0071] In summary, the detection device of the communication module according to the embodiment of the present invention includes at least two shielding boxes, a signal control unit, a test unit and a control unit, wherein at least two shielding boxes are connected in series, one shielding box is suitable for placing the acquisition terminal, and the remaining shielding boxes are suitable for placing the communication module to be tested, the acquisition terminal is configured to be networked with each communication module to be tested, and to collect data for each communication module to be tested, the signal control unit is connected to each shielding box, and is configured to control the communication signal input to the remaining shielding box, so as to adjust the station area topological level and topological path of the communication module to be tested, the test unit is connected to each shielding box, and is configured to test the communication performance between the acquisition terminal and each communication module to be tested, the control unit is respectively connected to the acquisition terminal, the signal control unit and the communication connection, and is configured to send test cases to the signal control unit, so that the signal control unit tests all the communication modules to be tested according to the test cases, and generates test results according to the data collected by the acquisition terminal and the performance test results of the test unit. Thus, the control unit and the acquisition terminal, the acquisition terminal and the communication module to be tested, and the multi-level communication module topology to be tested are detected, and the full-link communication detection is realized, thereby improving the detection effect.

[0072] Corresponding to the above embodiment, the embodiment of the present invention further provides a detection system for a communication module.
