Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 2, a kind of laser image real-time monitoring device measuring relative displacement, optical reference module 8 is arranged in monitored structure, laser image acquisition module 7 is arranged on reference field, the generating laser 1 that described optical reference module 8 comprises 2-d rotating platform 2 and is fixedly mounted with thereon, described 2-d rotating platform 2 adopts driver and reductor Component driver; Described laser image acquisition module 7 comprises optical filtering transmission screen 3 and CCD camera 4, and the visual field of described CCD camera 4 is parallel with described optical filtering transmission screen 3, and described optical filtering transmission screen 3 is positioned at the focal position place of described CCD camera 4; The laser that described generating laser 1 is launched is beaten on described optical filtering transmission screen 3; Described CCD camera 1 carries out image data acquiring to the laser facula on described optical filtering transmission screen 3, and gives monitoring host computer 6 by view data real-time Transmission; Described monitoring host computer 6 is connected with alarm 9, described driver is controlled by described monitoring host computer 6, and driver drives 2-d rotating platform 2 carries out horizontal deflection or pitching up and down, and then adjusts the sensing of generating laser 1, after adjusting to the right place in direction, 2-d rotating platform can be automatically locked.
In the present embodiment, described CCD camera 4 carries out communication with described monitoring host computer 6 by wireless data transfer module 5, adopts the mode of wireless telecommunications to carry out data transmission.Described alarm 9 adopts audible-visual annunciator.
In order to meet requirements for high precision of the present invention, require that the adjustment resolution of laser beam is mated with the accuracy of detection of image capture module 7.As shown in Figure 2, when generating laser 1 send laser beam rotate to B direction from A direction time, turn over a low-angle α, the distance that correspond to laser facula movement is Δ d.Because the distance L between generating laser 1 and optical filtering transmission screen 3 is far, can be similar to and think that the conversion relational expression of α and Δ d is:
Δd＝L×α
Suppose that the accuracy of detection of image capture module 7 is 1mm, so the adjustment resolution of laser beam also should be 1mm, and the adjustment resolution of laser beam depends on the rotation Adjustment precision of 2-d rotating platform.When detecting distance is 50m, as shown from the above formula: the rotation Adjustment precision of 2-d rotating platform is approximately 4 ".In order to meet laser beam adjustment resolution requirement, the present invention uses the reductor of 60:1 reduction gear ratio, and then arranging driver is 6400 segmentations, can realize 3.375 " rotation Adjustment precision, meet laser beam adjustment resolution requirement.
In sum, under the condition that the reduction gear ratio of the reductor of the utility model in described driver and reductor assembly is determined, the adjustment resolution of the laser beam that described generating laser sends is controlled by the segmentation arranging driver.
The utility model, in order to improve the responding range of monitoring, is not use CCD camera 4 directly to take laser beam, but is projected by laser beam on one piece of optical filtering transmission screen 3 before CCD camera 4, then use the hot spot that in camera 4 photographed screen, laser is formed.
An above-mentioned monitoring host computer can carry out communication with multiple wireless data transfer module, monitors the data message of multi-path laser image capture module simultaneously, and carries out data processing to it.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
