Embodiment Construction
[0029] The technical solutions of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0030] Such as figure 1 As shown, the device is L-shaped, and consists of a handle, a device main body, a switch button, a display screen, an extension rod and a measuring probe. The measurement circuit, high-speed acquisition circuit and power supply circuit are placed inside the main body of the device, and the switch button and display screen are placed on one side of the main body of the device. The measuring probe is connected with the internal measuring circuit of the main body of the device through a cable. The extension rod is a hollow rod, and the cables are placed inside. The battery is placed inside the handle. The surface of the handle is a conductor, which is connected to the device ground. The astronauts share the ground with the measuring device by holding the handle tightly.
[0031] The measuring probe is used for m...

The invention discloses a handheld device for measuring surface potential of lunar base external equipment, which is L-shaped and comprises a handle, a device main body and a measuring probe, wherein the device main body is a cuboid box body, one side of the box body is embedded with a display screen, one side opposite to the display screen is connected with a measuring probe through an extension rod, and a handle is arranged below the box body; a measurement acquisition circuit is arranged in the box body; the measuring probe is used for measuring by contacting with the surface of to-be-measured equipment and transmitting a measuring signal to the device main body through a cable; and the measurement acquisition circuit is used for performing measurement acquisition and conversion processing on the measurement signal and then transmitting the measurement signal to a display screen for displaying a potential amplitude. When an astronaut carries the device, the surface potential of external equipment of a base can be conveniently measured, meanwhile, the surface potential of special terrains such as a lunar pit and a huge stone can be measured, and the device is light in weight, small in power consumption, convenient to carry and use and capable of directly displaying the surface potential.
Description
technical field [0001] The invention relates to the field of aerospace and the technical field of detection loads working in the lunar environment, in particular to a hand-held device for measuring the surface potential of external equipment on a lunar base. Background technique [0002] With the successful implementation of my country's lunar exploration project, manned moon landings will be carried out in the future, and a permanent lunar base will be built on the moon. In the construction of the lunar base, in addition to various equipment inside the base, a variety of detection equipment outside the base will also be arranged. [0003] Since the ground of the earth is a good conductor, as long as the equipment in different locations is connected to the ground, the surface potential of all equipment can be guaranteed to be the ground. People can also maintain the same potential with the earth by contacting devices such as "static discharge piles" connected to the earth. ...
