In order to make those skilled in the art person understand technical scheme among the utility model embodiment better, and the above-mentioned purpose of the utility model embodiment, feature and advantage can be become apparent more, below in conjunction with accompanying drawing technical scheme among the utility model embodiment is described in further detail.
Referring to Fig. 2 and Fig. 3, wherein Fig. 2 is the perspective view of the upright position photoelectric detection system of the utility model ball-shaped camera, and Fig. 3 is the partial structurtes enlarged diagram of the upright position photoelectric detection system of the utility model ball-shaped camera.
The upright position photoelectric detection system of this ball-shaped camera comprises: movement erecting frame 301, integrated movement 302, vertical detection axle 303, bolster 304, auxiliary support frame 305, optoelectronic switch 306, switching circuit board 307, vertical support frame 308 and synchronous pulley 309.
Wherein, auxiliary support frame 305 is installed on the vertical support frame 308, be separately installed with bolster 304 on vertical support frame 308 and the auxiliary support frame 305, on the bolster 304 bearing is housed, the Bearing Installation that is positioned at vertical support frame 308 1 sides is on synchronous pulley 309, synchronous pulley 309 is installed on the side of movement erecting frame 301, the Bearing Installation that is positioned at auxiliary support frame 305 1 sides is on vertical detection axle 303, vertical detection axle 303 is installed in an other side of movement erecting frame 301, and integrated movement 302 is installed on the movement erecting frame 301.Optoelectronic switch 306 is housed on the switching circuit board 307, and switching circuit board 307 is installed on the auxiliary support frame 305.
Motor (unmarked among the figure) also is housed on vertical support frame 308, and the kinematic train that this motor and synchronous pulley 309 are formed drives integrated movement 302 rotations.
Below in conjunction with Fig. 2 and Fig. 3, describe the principle of work of the upright position photoelectric detection system of the utility model ball-shaped camera in detail:
The motor that is installed on the vertical support frame 308 rotates, and drives integrated movement 302 vertical direction that are installed on the movement erecting frame 301 by synchronous pulley 309 kinematic trains and rotatablely moves; Simultaneously, be installed on vertical detection axle 303 on the movement erecting frame 301 and also follow integrated movement 302 and rotate, and the outer ring of vertical detection axle 303 alignment light electric switch 306 just in time.Optoelectronic switch 306 installation sites just in time are in the position that integrated movement 302 rotates to 90 degree, when integrated movement 302 rotates to 90 degree positions, the intersection of the outer ring breach of vertical detection axle 303 just in time passes through optoelectronic switch 306, and the signal that triggers optoelectronic switch 306 produces saltus step.
Position as shown in Figure 3, suppose that integrated movement 302 present positions are the position less than 90 degree, then the non-barbed portion of vertical detection axle 303 outer rings is just in time in the centre of optoelectronic switch 306, sheltered from the light that light emitting diode sends in the optoelectronic switch 306, suppose when carrying out circuit design, at this moment corresponding optoelectronic switch 306 output low level signals; The then drive by motor, integrated movement 302 continues to the directions rotation greater than 90 degree, and when through the position of 90 degree, the output signal of optoelectronic switch 306 produces saltus step, become high level from low level, then spherical camera can be made upset processing accurately to image according to this signal; When integrated movement 302 rotate to greater than 90 the degree the position time, the barbed portion of vertical detection axle 303 outer rings just in time is positioned at the centre of optoelectronic switch 306, the light that light emitting diode sends in the optoelectronic switch 306 is not blocked, therefore optoelectronic switch 306 can corresponding output high level signal, as shown in Figure 5.Hence one can see that, and the ball-shaped camera in the embodiment of the present application owing to can access skip signal accurately in 90 degree positions, therefore can in time carry out the image upset when carrying out Flame Image Process.
In addition, in the photoelectric detection system of the upright position of existing ball-shaped camera, be the ball-shaped cameras of 180 degree for vertical rotation angle range, when integrated movement is rotating to 90 when spending, the semaphore of its both sides is not distinguished, and therefore needs to use software that signal is carried out complicated judgement; And use the upright position photoelectric detection system of the ball-shaped camera that above-mentioned the embodiment of the present application provides, because the breach of vertical detection axle outer ring just in time is circumference half, and intersection is in 90 degree positions, therefore integrated movement is opposite fully at the signal of 90 degree both sides, position, provides convenience for by software signal being judged thus.
Referring to Fig. 4, be the structural representation of vertical detection axle in the utility model.This vertical detection axle 303 has the circumferential outer ring, has breach on this circumferential outer ring, and barbed portion 3032 as shown in FIG., removes barbed portion 3032 and is non-barbed portion 3031.
This outer ring with breach is positioned at the centre of optoelectronic switch 306, breach accounts for half of circumferential outer ring, the intersection of non-breach rotates to the position of 90 degree on breach and the described circumferential outer ring corresponding to described integrated movement 302, signal when therefore optoelectronic switch can provide integrated movement 302 to be positioned at 90 degree positions, and, because the signal of integrated movement 302 when the both sides, position of described 90 degree is opposite fully, as shown in Figure 5, therefore ball-shaped camera is when carrying out Flame Image Process, can obtain skip signal accurately in 90 positions, therefore the image upset can be in time carried out, and error can be do not produced.
The embodiment that is provided by above-mentioned the utility model as seen, the upright position photoelectric detection system of the ball-shaped camera among the utility model embodiment, on the movement erecting frame, be connected with the vertical detection axle, this vertical detection axle has the circumferential outer ring that has breach, optoelectronic switch is arranged on the position relative with this circumferential outer ring, the outer ring that promptly has breach is positioned in the middle of the optoelectronic switch, therefore in integrated movement rotary course, when the intersection of outer ring breach passes through optoelectronic switch, can be so that the signal of optoelectronic switch produces saltus step, therefore can be so that integral machine core accurate trigger pip when rotating to 90 degree positions avoids the image upset to produce error.
Above-described the utility model embodiment does not constitute the qualification to the utility model protection domain.Any modification of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
