step S130: and operating the slave device by using the working power supply.
In this embodiment, an interface (such as a power supply interface) of the master device is integrated with a plurality of power supply lines and a plurality of operation enabling signal lines corresponding to different voltages, where the interface may be a peripheral interface of the master device, and the slave device has a power receiving interface corresponding to the power supply interface of the master device, where the power receiving interface is integrated with the power supply lines and the operation enabling signal lines corresponding to the master device, that is, the slave device is electrically connected to the power supply lines and the operation enabling signal lines corresponding to the one interface of the master device through the plurality of power supply lines and the operation enabling signal lines in the one interface. It can be understood that the working enabling signal line can be a shielded twisted pair, the multiple power supply lines and the multiple working enabling signal lines of the slave device can be used as a group of lines, the multiple power supply lines and the multiple working enabling signal lines of the master device can be used as a corresponding group of lines, and in practical application, the two groups of lines of the interface are connected in a flexible line connection or plug-in connection mode, so that the interface of the master device is electrically connected with the interface corresponding to the slave device.
As shown in fig. 2, a schematic diagram of a power supply interface of a main device according to an embodiment of the present application is provided, where one interface of the main device is integrated with a 5V start power supply line, a communication line, a 12V operation enabling signal line, a 12V power supply line, a 24V operation enabling signal line, a 24V power supply line, a 110V operation enabling signal line, a 110V power supply line, and a ground line. It is understood that if the normal operation voltage of the slave device is 24V, the 12V operation enable signal line, the 12V power supply line, the 110V operation enable signal line, and the 110V power supply line in the slave device interface may be in an interrupted state.
