[0100] 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.

[0101] The BPLC communication module single network networking consistency test method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the device to be tested 102 establishes a connection with the test cabinet 104 through the carrier power line, and the test cabinet includes a protocol test unit, a consistency evaluation module and a memory. The protocol test unit can generate the address information of the device to be tested that the device to be tested wants to communicate with. The device to be tested establishes communication with the test cabinet according to the address information. At the same time, the test cabinet 104 can directly capture the associated message during the communication process, and use the consistency evaluation module in the test cabinet 104 to evaluate the associated message. In response to the test request initiated by the user, the test cabinet 104 uses the carrier power line to establish a connection with the BPLC communication module of the device to be tested 102, and generates the simulated device address information according to the test request through the protocol test unit, and then sends the simulated device address information to the device to be tested 102. The device to be tested 102 establishes communication with the test cabinet 104 based on the simulated device address information to receive the associated message fed back by the device to be tested 102 to the test cabinet 104. When the associated message is received within a preset time, the associated message is evaluated for consistency through the consistency evaluation module to generate the test result of the BPLC communication module of the device to be tested. The device to be tested 102 may be a power terminal device, such as a voltmeter, an ammeter, etc., or a central control device, such as a monitoring and data acquisition device, an energy management device, a distributed control device, etc.

[0102] In an exemplary embodiment, Figure 2 As shown, a BPLC communication module single network networking consistency test method is provided, and the method is applied to Figure 1 The test cabinet in FIG. 1 is taken as an example to illustrate, including the following steps S201 to S203.

[0103] in:

[0104] Step S201, in response to a test request initiated by a user, a connection between a test cabinet and a BPLC communication module of a device to be tested is established using a carrier power line, and simulated device address information is generated according to the test request by a protocol test unit.

[0105] Among them, the BPLC (Broadband Power Line Communication) communication module can be understood as a communication device that uses power lines for data transmission and transmits digital signals through power lines.

[0106] For example, in response to a test request initiated by a user, the test cabinet 104 uses a carrier power line to establish a connection between the test cabinet 104 and the BPLC communication module of the device to be tested 102, and generates, through the protocol test unit, simulated device address information of a device with which the device to be tested wants to establish communication according to the test request. Using a carrier power line to connect the device to be tested and the test cabinet lays an environmental foundation for testing the communication between the BPLC communication module of the device to be tested and the test cabinet.

[0107] Step S202, sending simulated device address information to the device under test; the simulated device address information is used for the device under test to establish communication with the test cabinet based on the simulated device address information, so as to receive the associated message fed back by the device under test to the test cabinet.

[0108] The association message can be understood as an association feedback message or an association request message, wherein the association feedback message is generated by the device under test responding to a certain information sent by the test cabinet, and the association request message is a message generated by the device under test initiating an association request to the test cabinet.

[0109] Optionally, the test cabinet 104 sends the simulated device address information to the device under test 102, and the device under test 102 establishes communication with the test cabinet based on the received simulated device address information. After the communication is successfully established, the test cabinet 104 receives the associated message fed back by the device under test 102. The communication mechanism based on the simulated device address information improves the interaction efficiency between the test cabinet and the device under test.

[0110] Step S203: When the associated message is received within a preset time, the consistency evaluation module performs consistency evaluation on the associated message to generate a test result of the BPLC communication module of the device to be tested.

[0111] For example, when the associated message is received within the preset time, the associated message is evaluated for consistency through the consistency evaluation module to generate the test result of the BPLC communication module of the device to be tested. In other words, in fact, the test needs to meet two necessary conditions. One is that the time when the test cabinet receives the associated message cannot exceed the preset time range. Second, the associated message also needs to pass the consistency evaluation of the consistency evaluation module. At this time, the BPLC communication module test of the device to be tested passes; similarly, there are also two situations when the test fails. One is that the associated message is not received or the associated message is not received within the preset time. The second is that the associated message is received within the preset time, but the associated message does not pass the evaluation of the consistency evaluation module. The reliability and accuracy of the test results of the BPLC communication module of the device to be tested are ensured by the dual conditions of receiving the associated message within the preset time and performing the consistency evaluation.

[0112] In the above-mentioned BPLC communication module single network networking consistency test method, by responding to the test request initiated by the user, the connection between the test cabinet and the BPLC communication module of the device to be tested is established by using the carrier power line, and the simulated device address information is generated according to the test request by the protocol test unit, and the simulated device address information is sent to the device to be tested. The simulated device address information is used for the device to be tested to establish communication with the test cabinet based on the simulated device address information, so as to receive the associated message fed back by the device to be tested to the test cabinet, and when the associated message is received within the preset time, the consistency evaluation module performs consistency evaluation on the associated message, and generates the test result of the BPLC communication module of the device to be tested. By setting the test cabinet, the communication between the physical master and slave modules of different models is realized, and the relevant communication messages can be directly obtained and verified, which improves the test accuracy.

[0113] In one embodiment, when the device to be tested is a central control device, and the test request is a test request of the central control device to access the network through a site;

[0114] Generating simulated device address information according to the test request through the protocol test unit includes: generating the site device address information through the protocol test unit according to the site network access test request of the central control device;

[0115] Sending simulated device address information to the device to be tested includes: sending an add slave node command to the central control device; the add slave node command carries the site device address information, and the add slave node command is used to instruct the central control device to establish communication with the test cabinet based on the site device address information, and feed back a central beacon to the test cabinet;

[0116] When an associated message is received within a preset time, the associated message is evaluated for consistency by a consistency evaluation module to generate a test result of the BPLC communication module of the device to be tested, including: when the test cabinet receives a central beacon, an associated request frame is sent to the device to be tested, and an associated feedback message fed back by the device to be tested in response to the associated request frame is received; when an associated feedback message is received within a preset time, the associated feedback message is evaluated for consistency by a consistency evaluation module to generate a test result of the BPLC communication module of the central control device.

[0117] Optionally, when the device to be tested is a central control device, and the test request is a test request for the central control device to access the network through a site, the test cabinet 104 first passes through the protocol test unit, simulates and generates the site device address information according to the test request for the central control device to access the network through the site, and then sends an add slave node command to the central control device, wherein the add slave node command carries the site device address information, and the add slave node command is used to instruct the central control device to establish communication with the test cabinet 104 based on the site device address information, and feedback the central beacon to the test cabinet, and when the test cabinet 104 receives the central beacon, it sends an association request frame to the device to be tested 102, and receives an association feedback message fed back by the device to be tested in response to the association request frame, and when the association feedback message is received within a preset time, the consistency evaluation module performs a consistency evaluation on the association feedback message, and generates a test result of the BPLC communication module of the central control device. The test cabinet can efficiently and comprehensively evaluate the BPLC communication module of the central control device, ensure the performance and reliability of the device, and improve the test efficiency and test accuracy.

[0118] In an exemplary embodiment, when the test request is a central control device network access test request through a level 1 single site;

[0119] The method comprises: simulating and generating, by the protocol test unit, the address information of the site device according to the site network access test request of the central control device through the protocol test unit, including: simulating and generating, by the protocol test unit, the address information of the target site device according to the level 1 single site network access test request of the central control device through the protocol test unit;

[0120] Sending a slave node add command to the central control device includes: sending a first slave node add command to the central control device; the first slave node add command carries target site device address information, and the first slave node add command is used to instruct the central control device to establish communication with the test cabinet based on the target site device address information, and feed back a central beacon to the test cabinet.

[0121] For example, it is applied to Figure 3 In the environment shown, the test cabinet 104 serves as a STA (Station Device), the device to be tested 102 serves as a CCO (Central Control Organizer) to be tested, and the method for CCO to pass the level 1 single-site network access test includes two cases of allowing and rejecting, wherein (the following is a specific example of implementing the above method):

[0122] like Figure 4 As shown, a method for a CCO to pass the Level 1 single-site network access test (permitted) is provided. The test process of the method is as follows:

[0123] Process 1: Connect the device (i.e., test cabinet), and after power-on initialization, the software sets the DUT target carrier operating frequency band through the transparent physical device.

[0124] Process 2: The software (i.e., the test cabinet) sends the "add slave node" command to the CCO, sends the MAC address of the target network site to the CCO, and waits for "confirmation."

[0125] Process 3: After receiving the "central beacon", the software sends an "association request" frame and starts a timer for 15 seconds.

[0126] Process 4: If no "association confirmation" or "association summary" message with a "result" of 0 or 10 is received for the "association request" frame (within the set target frequency band) within the scheduled time, the test fails.

[0127] Process 5: After receiving the message, call the consistency evaluation module. If they are consistent, the test passes and the test ends.

[0128] like Figure 5 As shown, a method for a CCO to pass the Level 1 single-site network access test (rejection) is provided, and the test process of the method is as follows:

[0129] Process 1: Connect the device, power on and initialize it, and then the software sets the DUT target carrier operating frequency band through the transparent physical device.

[0130] Process 2: The software issues the "Add Slave Node" command, sends the MAC address of the random non-target network site to the CCO, and waits for "confirmation".

[0131] Process 3: After receiving the "central beacon", the software sends an "association request" frame and starts a timer for 15 seconds.

[0152] Process 3: After the timing time is up, the software selects the CSMA time slot, sends the forwarded "association request" frame, and starts the timing for 10 seconds.

[0153] Process 4: Within the scheduled time, if the "association confirmation" frame is received, the consistency evaluation module is called, and the test passes if it meets the requirements.
