An alternating current/direct current input device includes an appliance input socket and an information and communications technology (ICT) device. The ICT device is powered by the appliance input socket. The appliance input socket includes a ground contact, a positive electrode contact, a negative electrode contact, and a signal switch. A contact depth of the signal switch in the appliance input socket is less than a contact depth of the positive electrode contact or the negative electrode contact in the appliance input socket. The signal switch is configured to generate a control signal when a direct current connector is separated from the appliance input socket. The control signal can be used to enable the ICT device to disconnect the appliance input socket from a conductive electrode of the direct current connector after the ICT device enters a no load state.

A moon-based in-situ condition-preserved coring multi-stage large-depth drilling system and method therefor. The system includes a rotary plate provided inside a lander, an in-situ condition-preserved coring tool provided on a surface of the rotary plate, a space frame provided on a surface of the rotary plate, a working platform provided on a top of the space frame, a mechanical arm provided on a bottom surface of the working platform, and a camera provided on the bottom surface of the working platform, the mechanical arm is fixedly connected to the working platform, and the camera is fixedly connected to the working platform. By controlling the mechanical arm to place the in-situ condition-preserved coring tool on the moon surface, and using the in-situ condition-preserved coring tool to sample the lunar soil on the moon surface, the coring operation problem of the lunar soil is solved.
