Frost prevention type wireless transmission night-vision device

Abstract

The invention discloses a frost prevention type wireless transmission night-vision device. The device comprises an objective lens, an electric heating ring, a CCD imaging module, a main control ASIC, a wireless receiving and dispatching module, an infrared illuminator, an illuminance detection head, a temperature sensor, a microphone, a micro liquid crystal display, an eye lens and a power source module. According to the device, the main control ASIC controls the power-on and power-off states of the electric heating ring so that the heating for the objective lens can be maintained, it is avoided that the objective lens is frozen caused by a low temperature in a frosty day or in a snowy day, and the sealing effect of rime frost and the reflection to light are eliminated; by connecting the wireless receiving and dispatching module to the main control ASIC, the wireless communication connection between the main control ASIC and a user terminal can be achieved, a user can conduct on-line control and receive video signals through the wireless receiving and dispatching module, therefore, the human factors are reduced in the shooting process of a photographic device, so that the whole shooting process can be conducted in a unmanned state, the device is extremely suitable for shooting wild animals and plants in the wild, the human factors are reduced, and it is facilitated to obtain high-quality and real video data by shooting.

Description

technical field [0001] The invention relates to an imaging device, in particular to a frost-proof wireless transmission night vision device. Background technique [0002] The night vision device is a nighttime external sight with an image intensifier as the core device, and uses the light reflected by the target under weak light to be enhanced into a visible image that the human eye can perceive on the fluorescent screen through the image intensifier to observe and aim at the target. Infrared night vision device is a military night vision device using photoelectric conversion technology. It is divided into two types: active and passive: the former uses infrared searchlights to irradiate the target, and receives reflected infrared radiation to form an image; the latter does not emit infrared rays, but relies on the target's own infrared radiation to form a "thermal image", so it is also called "thermal image". instrument". [0003] Visible light at night is very weak, but i...
