Abstract
The invention discloses a temperature control structure for an infrared high-speed spherical camera. The infrared high-speed spherical camera comprises a spherical shell, a camera shell and a connecting shell, wherein the internal space of the connecting shell and the internal space of the camera shell form integer communicated space through a hollow connecting part; a fan is arranged in the connecting shell; and when the camera works, the fan starts to rotate so that the air in the connecting shell and the camera shell flows circularly. A large amount of heat generated by an infrared lamp in the camera shell is taken away by continuously and circularly flowing air, so that the heat of the infrared lamp is dispersed in the internal space of the connecting shell and the camera shell; and heat exchange is performed between the heat of the infrared lamp and the external through the surfaces of the connecting shell and the camera shell, so that the superficial area, for radiating to the external, of the camera is increased, the radiating efficiency of the camera is improved, the working environmental temperature of the camera is reduced effectively, and the working life of the camera and the infrared lamp is prolonged.
Description
Technical field
The present invention relates to the technical field of video camera, be that a kind of shell that connects forms the inner space that is communicated with the shooting shell by connecting portion specifically, in the connection enclosure fan is set, make the air flows in the above-mentioned inner space, thereby change the structure of controlling temperature of the infrared high-speed dome camera of camera heat distribution state.
Background technology
High-speed dome camera is a kind of intelligent video camera front end, and full name is the high-speed intelligent ball-shaped camera, and perhaps integration high speed ball intelligent sphere perhaps is called for short quick, is called for short clipping the ball.Clipping the ball is the most complicated and best video camera front end of general performance effect of supervisory control system, can adapt to high density, the most complicated monitoring occasion.
High-speed dome camera is the quite high product of a kind of integrated level, integrated The Cloud Terrace system, communication system and camera chain, the The Cloud Terrace system is meant the rotating part of driven by motor, communication system is meant that camera chain is meant the all-in-one movement of employing to the control of motor and to image and Signal Processing part.And between several big systems, what play horizontal connection is a master control core cpu and power unit.Power unit by with each big system between be connected power supply, wherein little electric currents power supply such as diode, triode is adopted in many places, and core cpu realizes that all functions normally move.
Specifically, high-speed dome camera adopts " accurate differential stepping motor " to realize location fast and accurately, the rotation of clipping the ball, and these all are to realize by the instruction that cpu sends.With the image of video camera, the cpu that function is write into clipping the ball, when can be implemented in the control The Cloud Terrace picture transmission is come out, and can realize the multiple function control of video camera, for example functions such as white balance, shutter, aperture, zoom, focusing simultaneously.
Fig. 1 is the structural representation of the high-speed dome camera of prior art.
As shown in Figure 1, in the general high-speed dome camera, spherical shell 1 forms the outward appearance on high-speed dome camera top, and high-speed dome camera is fixed on the installation site, and spherical shell generally all is to adopt aluminium alloy, general two kinds of being divided into casting and punching press again of aluminium alloy.Top Connection Block (not shown) is arranged on the movement that the spherical shell inboard is used to install and fix high-speed dome camera, and the top Connection Block is provided with the upper insert of transmission signals and power supply usefulness.Translucent cover 3 forms the outward appearance of high-speed dome camera bottom, and translucent cover is formed by PC transparent material pressure injection, can guarantee image effect and light transmittance, can also play anti-riot, dustproof effect simultaneously.Movement 4 comprises The Cloud Terrace and is connected camera 2 on the The Cloud Terrace, movement and top Connection Block fix, be arranged in the space of spherical shell and translucent cover formation, lower insert on the movement matches with the upper insert of top Connection Block, interfixes by screw or buckle between movement and the top Connection Block.
Fig. 2 is the structural representation of the infrared high-speed dome camera of prior art.
As shown in Figure 2, be provided with a plurality of infrared lamps 5 that constitute by infrared-emitting diode around the camera 2 of infrared high-speed dome camera, when camera is worked, infrared lamp is forwards launched the sightless high wavelength infrared light of naked eyes, after being reflected by object on every side, infrared light received by camera, and be converted into optical imagery, thereby be implemented in the monitoring camera under night or the low-light (level).
Infrared lamp around the camera setting is divided into closely infrared lamp 5a, middle distance infrared lamp 5b and remote infrared lamp 5c, produces the different infrared ray of irradiation distance successively, because the power difference of three kinds of different infrared lamps, its calorific capacity is also inequality.In, the heating of remote infrared lamp is more.A plurality of infrared lamps are fixed and are arranged on the circuit board, and circuit board is the infrared lamp power supply.
But, there is following not enough point in the aforesaid prior art:
In the infrared high-speed dome camera of prior art, infrared lamp directly is fixed on the circuit board, because circuit board is to cover copper to form on the substrate of insulation, the heat-sinking capability of circuit board itself is very poor, in, the heat that produces of remote infrared lamp can't disperse timely, thereby make infrared lamp be in higher working temperature all the time, can greatly shorten the working life of infrared lamp and camera.For improving the heat-sinking capability available technology adopting metallic circuit carrying infrared lamp of circuit board, but the cost of metallic circuit is too high, promoted the whole cost of product, and owing to have insulating barrier equally in the metallic circuit, the radiating effect of infrared lamp is not significant to be promoted.In addition, under low temperature environment, can cause camera to move, limit to the scope of application of video camera because temperature is crossed to hang down.
Summary of the invention
