An embedded digital duty recording device for infantry helmets

Abstract

The invention relates to an embedded digital on-duty recording device for an infantry helmet. The embedded digital on-duty recording device comprises an arc-shaped casing matched with an inner wall of the front end of a helmet body and a circuit device fixed in the casing. A miniature camera and a miniature microphone of the circuit device acquire scene audio / video data and transmit the data to a circuit control main board, the data are memorized in a temporary memory management module and output to a secure digital (SD) memory card to be memorized through denoising and exposure compensation treatment of a noise inhibition module and an exposure compensation module, and data on the SD memory card are led out from a universal serial bus (USB) data interface. The casing is formed by closing a front cover and a back cover, wherein two sides and the top end of the front cover are provided with installing holes in matched connection with hanging system positioning parts inside the helmet body. A system power supply switch, the USB data interface and the miniature microphone are fixed on the vertical edge of the lower end of the back cover, a support rod is further arranged on one side of the vertical edge, and a camera installing groove is fixed at the tail end of the support rod. The embedded digital on-duty recording device for the infantry helmet can be used for campaign-style law enforcement of on-duty persons and synchronous acquisition and memory of the scene audio / video data.

Description

technical field [0001] The invention relates to a digital on-duty recording device, in particular to an embedded digital on-duty recording device for infantry helmets. Background technique [0002] The digital on-duty recording device can collect and store live audio and video data in real time through the integrated audio and video device, and provide effective technical support for on-duty personnel to analyze and deal with emergencies. Compared with the traditional on-duty recording device, it has the characteristics of convenient use and concealed recording information. At present, most of the on-duty personnel are equipped with wearable or handheld digital on-duty recording devices when performing tasks. During operation, the shooting direction and shooting angle need to be adjusted frequently, which is not convenient.

Problems solved by technology

At present, most of the on-duty personnel are equipped with wearable or handheld digital on-duty recording devices when performing tasks. During operation, the shooting direction and shooting angle need to be adjusted frequently, which is not convenient.

Although there are also examples in the prior art that the digital on-duty recording device is combined with the helmet of the on-duty personnel, such as by punching holes on the helmet or using the badge on the helmet to install the camera of the recording device concealedly, but due to the material characteristics of the helmet, such as the infantry helmet Due to the bulletproof feature, the installation of the digital duty recording device is not firm enough, and the stability of the entire system cannot fully meet the needs of the law enforcement personnel on duty.
