The host computer and the solid-state power controller are communicatively connected via an SCI bus. The host computer is used to generate a corresponding test interface according to a loaded configuration file, send SSPC test commands to the solid-state power controller, and process the SSPC test results reported by the solid-state power controller after executing the SSPC test commands. The solid-state power controller is used to execute the SSPC test commands and report the test results.

[0011] Figure 2 This is a flowchart of a method according to an embodiment of the present invention. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. It should be noted that these descriptions of embodiments are intended to aid in understanding the invention and do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0013] See Figure 1 The diagram shows the overall architecture of the general test software for solid-state power controllers (SSPCs). The architecture includes the test software, the SCI bus, and the SSPC control software.

[0014] See Figure 2 The diagram shows the method flowchart. The method includes the following steps: Determine if the SSPC being tested is a new product. If yes, load the newly created configuration file for the SSPC being tested. If not, use the existing configuration file for the SSPC being tested. A new product refers to an SSPC that has never been used before. The configuration file includes parameters required for SSPC testing, such as the number of channels, external channel status, number of boards, instruction status, board status, product status information, self-test information, voltage sampling coefficient, and current sampling coefficient.

[0015] The test software loads the configuration file.

[0016] The testing software generates a test interface based on the currently loaded configuration file.

[0017] The test software sends test commands to the SSPC control software; The SSPC control software receives test commands and executes test operations. The SSPC control software reports the test results; The testing software receives test results from the SSPC control software. The testing software processes the received test results.

[0018] The solid-state power controller (SSPC) being tested requires a unique configuration file. This file contains parameters necessary for testing, including the number of channels, external channel information, number of boards, command information, board information, product status information, self-test information, voltage sampling coefficient, and current sampling coefficient. The test software can select the configuration file for the currently tested SSPC and automatically generate an interface based on it. The test software sends test commands to the SSPC control software via the SCI bus and receives and processes the test results fed back by the SSPC control software.

[0019] The general testing characteristics of SSPC control software are as follows: SSPC control software receives test commands sent by test software via the SCI bus, executes test operations, and reports test results to the test software. Communication between the SSPC control software and test software includes the sending, receiving, and parsing of the following general commands: channel control command, channel reset command, maintenance self-test command, channel enable command, command sent under channel power-on trip status, channel status query command, software version query command, maintenance self-test status query command, channel parameter query command, channel rated current setting command, channel overcurrent protection parameter setting command, channel current calibration coefficient setting command, channel voltage calibration coefficient setting command, and channel trip data record query command.
