Embedded digital on-duty recording device for picketing helmet

Abstract

The invention relates to an embedded digital on-duty recording device for a picketing helmet. The embedded digital on-duty recording device comprises an arc-shaped casing matched with an inner wall of the front end of a picketing helmet body and a circuit device fixed in the casing. The circuit device consists of an audio / video acquiring device and an intercom system. The casing is opened and is divided into a plurality of cavities, and the periphery of each cavity is provided with a vertical edge abutting against the inner wall of the helmet body. A miniature microphone, a universal serial bus (USB) data interface, a system power switch and an intercom control switch of the intercom system are fixed on the vertical edge located at the lower portion of the casing. A lens mount rightly facing a helmet body insignia gap is fixed in the cavity located at the center of the casing, and a miniature camera is fixed on the lens mount. The outside of the left side of the casing is fixedly connected with earphones and the microphone of the intercom system. In addition, the casing is provided with a plurality of installing holes in matched connection with suspension system positioning parts inside the helmet body. The embedded digital on-duty recording device can be widely used for campaign-style law enforcement of on-duty persons and has functions including synchronous acquisition of audio / video data in a field, collaborative talkback and the like.

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 picket helmets. Background technique [0002] The digital on-duty recording device can collect and store live audio and video data in real time through integrated audio and video equipment, and provide effective technical support for picket personnel to analyze and deal with emergencies. At present, most of the pickets use wearable or handheld digital duty recording devices when performing tasks. Wearable digital duty recording devices are generally worn on the shoulder straps, belts and clothing of pickets. The shooting direction and angle are not accurate, and the wearing is cumbersome. However, the hand-held digital duty recording device is more likely to arouse conflicts because the shooting action is too direct, and the convenience is poor.

AI Technical Summary

Problems solved by technology

Wearable digital duty recording devices are generally worn on the shoulder straps, belts and clothing of pickets. The shooting direction and angle are not accurate, and the wearing is cumbersome, and the position of the equipment is relatively exposed, which can easily cause the other party’s overreaction

However, the hand-held digital duty recording device is more likely to arouse conflicts because the shooting action is too direct, and the convenience is poor.

Although there are also examples of combining digital duty recording devices with helmets in the prior art, these examples often need to consolidate the recording device by changing the appearance of the helmet body or adding some auxiliary fixing parts, which will inevitably cause the helmet to be inconvenient to wear and comfortable to wear. Poor sex

In addition, since there is no integrated communication equipment, the communication between the picket personnel also needs to wear walkie-talkies or other similar communication equipment, resulting in the inability of the picket personnel to achieve coordinated communication while on duty
