Abstract: A data conversion method applied to a data conversion device, including: receiving camera control signals transmitted by a remote control device; converting a format of the camera control signals to a protocol format of a camera; and transmitting the converted camera control signals to the camera. The data conversion device is connected to a gimbal and the camera, and the gimbal is controlled by the remote control device.

Abstract: A mounting device for an apparatus having a heat dissipation requirement; the apparatus is housed in a cabinet, and comprises a heat dissipation part; the mounting device comprises a box body (1) housed in the cabinet (4); the box body (1) comprises a peripheral wall (11) on the sides, and a first mounting surface and a second mounting surface respectively located at the ends of the peripheral wall (11) on the sides; the first mounting surface and the second mounting surface are oppositely disposed and form an opening in the rear wall of the cabinet; the first mounting surface is mounted around the opening inside the cabinet, and is provided with an opening corresponding to the opening thereon; the apparatus is mounted on the second mounting surface; the heat dissipation part pushes through the second mounting surface, and extends into the box body (1) but does not go beyond the first mounting surface.

Abstract: A testing finger (1) comprises a finger-shaped rod (2). A sharp end (3) of the finger-shaped rod (2) is connected with a testing part used for measuring a distance. The testing part is a group of testing heads, and the length of each testing head corresponds to minimum safe distances at different voltage levels in intrusion protection. The testing part is connected with the sharp end (3) of the finger-shaped rod (2) in a detachable insertion manner. The testing finger (1) can accurately determine whether the distance between a live part or a live lead which is not insulated in an electrical device and a protective part is greater than or equal to a minimum safety distance, thereby solving the problem in the prior art that the distance between the sharp end (3) of the finger-shaped rod (2) and the live part or the live lead cannot be accurately measured by a clamp in a situation of limited space.
