[0067] The embodiment sets a target end device connector, a loading end device connector and an Ethernet port switching module in the software loading device, wherein the target end device connector is used to connect the target end device, so that the software loading device can transmit data with the target end device. The loading end device connector is used to connect the loading end device, and is electrically connected with the target end device connector and the loading end device connector through the Ethernet port switching module, so that the loading end device connector can transmit the software loading data provided by the loading end device to the Ethernet port switching module. The Ethernet port switching module can convert the software loading data into an Ethernet protocol format and transmit it to the target end device through the target end device connector, thereby realizing software loading for the target end device through the software loading device. At the same time, the software loading device is provided with a power supply switching module, an enable signal switching module and a discrete quantity switching module, and the power supply switching module, the enable signal switching module and the discrete quantity switching module are electrically connected with the target end device connector, so that the power supply switching module, the enable signal switching module and the discrete quantity switching module can convert the power supply signal provided by the input power supply into the power supply excitation signal, the enable signal and the discrete quantity signal required by the software loading device for software loading of the target end device, and provide them to the target end device through the target end device connector, so that the software loading device can simulate the working environment required by the target end device for software loading, ensure that the target end device is in a safe and suitable state for software loading, and realize ground software loading of the target end device through the software loading device without installation of the target end device, thereby improving the efficiency and accuracy of software loading.
