Embodiment
Below will combine Figure of description and specific embodiment that the present invention is explained further details.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; Laser sedimentation deflection monitoring appearance of the present invention; Comprise the transmitter unit 15 and receiving element 16 that cooperatively interact; Transmitter unit adopts laser instrument 1, and receiving element comprises dimmer 2, light filter 3, linear array CCD image collecting unit 4, analysis and disposal system and solar cell 10, and linear array CCD image collecting unit 4 adopts ccd image sensor in the present embodiment; This analysis and disposal system comprise Drive and Control Circuit 5, A/D converter 6, singlechip chip 7 (or single-chip microcomputer microcomputer), RS485 EBI 8 and radio receiving transmitting module 9, and this analysis links to each other with host computer through radio receiving transmitting module 9 with disposal system.In the present embodiment, referring to Fig. 4, singlechip chip 7 is U4.Dimmer 2 is a stainless steel circular configuration, adds optical filter, can effectively cross other light beyond the filtering laser.Except dimmer 2, the solar cell 10, other parts all are fixed in the seal casinghousing.By the beam of laser of laser instrument 1 emission, can pass through dimmer 2, light filter 3 filters out the light except that laser.If relative deformation (amount of deflection) has taken place between transmitter unit 15 and the receiving element 16; Then corresponding variation also can take place in the position of laser radiation on linear array CCD image collecting unit 4; Corresponding variation also can take place in the signal of ccd image sensor output, calculates corresponding distortion through corresponding IMAQ, analysis and processing then.
Referring to Fig. 1; In the present embodiment; Transmitter unit 15 in groups is installed in respectively on adjacent two measuring points 12 with receiving element 16, and each measuring point 12 place is equipped with a support 11, and transmitter unit 15 is individually fixed in corresponding position on two supports 11 with 16 of receiving elements.The laser beam 13 that laser instrument 1 sends can arrive on the receiving element 16 on the adjacent stent 11, to monitor in real time.Further, can also on support 11, be equiped with laser angle adjusting knob 14, accommodation carried out in the laser instrument 1 and the position of receiving element 16 with convenient.
