The test results can be used to guide manufacturers in the development and iteration of intelligent converged terminals of the substation, providing a good technical guarantee for product quality and the later field trial operation stage. The interchangeability testing method 100 for the communication interface of the intelligent converged terminal module of the present invention begins at step 101.

[0047] In step 102, communication connections are established between the standard functional module and the intelligent converged terminal of the distribution area, the test system, and the virtual table; wherein, the module object establishes a communication connection with the test system through a communication interface.

[0048] Preferably, the method further includes:

[0049] A three-phase programmable power source is connected to the intelligent fusion terminal of the transformer substation to provide operating voltage and current to the test terminal.

[0050] In this invention, standard functional modules (local communication module, remote communication module, and extension module) and virtual tables are compiled from program source code, and the interchangeability of the communication interfaces of the intelligent converged terminal modules in the distribution area is tested using business interaction messages to verify whether the communication interfaces of each module of the intelligent converged terminal in the distribution area meet the business requirements.

[0051] like Figure 2As shown, the system architecture of this invention consists of a three-phase programmable source, a communication interface, a test system, standard functional modules (hardware and software), and a virtual meter.

[0058] In step 103, based on the module object virtualized by the standard functional module, the intelligent converged terminal of the distribution area, the test system, and the virtual table, the interchangeability test of the communication interface of the intelligent converged terminal module is performed to verify whether the communication interface of each module of the intelligent converged terminal of the distribution area meets the business requirements.

[0059] Preferably, when the test requirement is a management channel interchangeability test:

[0060] The test system loads the front-end machine, which calls the platform control protocol library to power on the intelligent fusion terminal in the control area.

[0061] After the standard function module is powered on, the test system sets the module object, IP address, and port number for the standard function module and the software standard function module through the front-end software to establish a connection with the test system; the software standard function module interacts with the intelligent converged terminal of the distribution area through the "front-end computer-serial server-standard function module";

[0062] The smart converged terminal in the distribution area sends the link negotiation request message to the software standard function module, and the standard function module organizes the response message and sends it uplink to the smart converged terminal in the distribution area.

[0063] The smart converged terminal in the distribution area will send the module information message to the software standard function module, and the software standard function module will organize the response message and send it uplink to the smart converged terminal in the distribution area.

[0064] The test system reads the module information of the smart converged terminal in the distribution area and compares it with the information of the set module objects to achieve the interchangeability test of the management channel.

[0065] Preferably, when the test requirement is a data channel interchangeability test:

[0067] The smart converged terminal in the distribution area interacts with the standard functional module of the software through the standard functional module data channel according to the identified module type, so as to realize the data channel interchangeability test.

[0068] This invention utilizes standard functional modules to replace actual modules, which not only reduces hardware costs but also improves testing efficiency. Specific test content is as follows: The interchangeability test of the communication interface of the intelligent converged terminal module in the distribution area can be further divided into management channel interchangeability testing and data channel interchangeability testing.

[0069] The management channel interchangeability test enables functions such as module identification, clock management, and file transfer.

[0070] Data channel interchangeability testing involves implementing different business data interaction functions for different functional modules.

[0071] The standard functional modules of this invention interact with the intelligent converged terminal, front-end machine, and virtual table in the distribution area via TCP / IP. The front-end machine encapsulates the standard functional modules, virtual table, and control protocol functions of the distribution system for use by the test system. Figure 3 As shown, the management channel interchangeability test process includes:

[0072] Step 1: The test system loads the front-end processor, which calls the platform control protocol library to control the terminal power-on.

[0073] Step 2: After the terminal is powered on, the test system sets the module type, IP address and port number of the standard function module through the front-end software, and the software standard function module establishes a connection with the test system.

[0074] Step 3: The software standard function module interacts with the intelligent converged terminal of the distribution area through "front-end machine - serial port server - standard function module (hardware)".

[0075] Step 4: The terminal sends the link negotiation request message to "Standard Functional Module (Hardware) - Serial Port Server - Front-end Machine - Standard Functional Module (Software)", and the Standard Functional Module (Software) organizes the response message and sends it to the terminal via uplink;

[0076] Step 5: The terminal sends the module information reading message to "Standard Functional Module (Hardware) - Serial Port Server - Front-end Machine - Standard Functional Module (Software)", and the Standard Functional Module (Software) organizes the response message and sends it to the terminal via uplink;

[0077] Step 6: Test the system to read the module information of the terminal and compare it with the information of the set module object to realize the interchangeability test of the management channel.

[0078] In this invention, the testing process for the interchangeability of management channels is as follows:

[0079] 1) The test system is set with standard functional module types: Module 1: Local communication module, Module 2: Load identification, Module 3: Remote communication module;

[0080] 2) The standard function module management channel waits for the intelligent converged terminal in the receiving area to initiate a link negotiation request, replies according to the module type set in the scheme, and notifies the test system of the reply data;

[0082] 4) The software standard function module management channel waits for the intelligent converged terminal in the receiving area to set the module clock and reply with an acknowledgment frame, and then notifies the test system of the reply data;

[0083] 5) The test system reads the module information of the smart converged terminal in the distribution area and determines whether the data returned by the smart converged terminal in the distribution area is consistent with the data replied by the standard functional module;

[0084] 6) When the virtual module manages the terminal clock, the terminal should be able to reply with clock information normally.

[0085] 7) Test the file transfer process initiated by the intelligent fusion terminal in the test system's operation area;

[0086] 8) The software standard function modules wait for the intelligent converged terminal in the distribution area to send files, and then notify the test system of the contents of the received files;

[0087] 9) After the file transfer is completed, the test system determines whether the file received by the software standard function module is consistent with the data of the file sent out;

[0088] Test complete.

[0089] In this invention, the data channel interchangeability test process for the remote communication module interface of the intelligent converged terminal in the distribution area is as follows:

[0090] 1) Power the smart converged terminal in the distribution area with 220V AC power;

[0091] 2) Check if there is approximately 4V output voltage at the 4V output port;

[0092] 3) Once 4V output is available, it immediately enters a loop waiting to receive AT commands from the smart converged terminal in the distribution area;

[0093] 4) When the software standard function module receives the first AT command sent by the smart converged terminal of the distribution area and returns a response command to the smart converged terminal of the distribution area, it records the current time T1 and notifies the test system; if the first AT command received is AT$MYPOWEROFF, it ignores this command, waits to receive the next AT command and return a response command to the smart converged terminal of the distribution area, records the current time T1 and notifies the test system.

[0094] 5) After time T1, when the next AT command is received from the intelligent converged terminal of the distribution area, record the current time T2 and notify the test system.

[0095] 6) The test system calculates the response time of the interactive command of the smart fusion terminal in the outer area based on the recorded time points, and determines whether the response time of the direct interactive command meets the technical specifications.

[0096] 7) The test system configures the wireless public network master station address, port, APN and other dialing parameters of the intelligent converged terminal equipment in the substation via the Ethernet port;
