[0051] Furthermore, there is also a communication connection between the execution module 101 and the control module 102, which is generally achieved through a network communication connection such as a network cable. The execution module 101 generally receives relevant parameter information of a preset detection program from the control module 102 based on the above-mentioned communication connection, with the execution program in the execution module 101 serving as the client and the control program in the control module 102 serving as the server, thereby enabling the execution module 101 to be controlled by the control module to execute the above-mentioned preset detection program for the device 100 to be detected.

[0064] Furthermore, the switch power submodule 1033 is generally used to process the filtered external electrical signal and adjust the strength of the external electrical signal to a level that meets the power supply requirements of the execution module 101.

[0069] Based on the storage space and operating system of the above-mentioned server device, the server device is equipped with database software and an access program for accessing the Manufacturing Execution System (MES system). The database is mainly used to store the inspection records and inspection result data of all previous preset inspection programs, so as to facilitate the subsequent retrospective review of the data of all previous preset inspection program runs, and at the same time provide data for confirming the program operation status when an error occurs during the inspection program operation.

[0070] In addition, the database also stores various types of devices 100 to be detected and the detection parameters required for their corresponding detection programs.

[0104] Next, the server device determines the detection parameters and the corresponding preset detection program according to the user's operation, adds the IP address of the card-type computer, and sends the above detection parameters and the corresponding preset detection program to the card-type computer through the communication connection. The card-type computer further forwards the above detection parameters and the corresponding preset detection program to the test baseboard through the communication connection relationship, and burns the above detection parameters and the corresponding preset detection program to the device to be detected 100 through the connection terminal.

[0105] The test baseboard executes the above-mentioned preset test program, tests the test items corresponding to each test parameter according to the preset test program, and uploads the test records and test results to the card-type computer through a communication connection after the test of each test item is completed. The card-type computer displays the above-mentioned test records and test results through a touch screen, and forwards the above-mentioned test records and test results to the server device. The server device saves the above-mentioned test records and test results to a database, thereby completing the entire test process.

[0106] In this way, the present application can support the burning and running of test programs for various types of photovoltaic converters such as single boards, positive electrodes, adapter single boards, adapter positive electrodes, power modules, etc. At the same time, by using a card-type computer connected to the server to communicate with the PC platform, the program burning and testing processes are merged, which greatly reduces the size of the detection device while maintaining the smoothness of data flow and the efficiency of test execution during the test.
