Description
Technical field
the present invention relates to a kind of measuring instrument, especially relates to a kind of improvement of CCD plumb instrument.
Background technology
plumb instrument measures the traditional instrument of different elevation horizontal direction displacement deformation, is widely used in horizontal shift and the dam deflection monitoring of the different elevation of dam.Vertical line measurement mechanism is divided into positive plumb line according to the fixed form of vertical line stiff end and falls plumb line two kinds of forms.Vertical line measurement mechanism freely draws the metal wire opened and sets up vertical reference, and plumb instrument is by the horizontal shift deformation measuring vertical line benchmark and near it, mark is understood in spacing trace change in time of mark.Although existing plumb instrument can play the effect of measurement still, measurement range is narrow, and precision is not high.
Summary of the invention
the present invention is exactly for the problems referred to above, provides a kind of measurement range wide, a kind of CCD plumb instrument that precision is high.
to achieve these goals, the present invention adopts following technical scheme, the present invention includes base plate, its structural feature: base plate is provided with guide rail, guide rail is provided with pole, pole is provided with pointolite, the other end corresponding with pointolite on base plate is provided with baffle plate, and the middle part of baffle plate is provided with lens, and what the rear side of baffle plate was corresponding with baffle plate is provided with dash receiver, dash receiver is provided with circuit board, circuit board is provided with CCD device; Mark is provided with between baffle plate and dash receiver.
as a kind of preferred version, described CCD device adopts CZ type CCD plumb line coordinator.
beneficial effect of the present invention.
1, measurement range is wide, and precision is high.
the optoelectronic integration displacement transducer that the present invention adopts liner CCD image sensor to be developed to detects microdisplacement, adopts the functions such as the program control driving of chip microcontroller CCD device, signal transacting and identification, data acquisition, calculating and communication.Simultaneously in apparatus structure design, adopt modular design, by CCD device and peripheral circuit integrated, and design specialized Making mold cabinet, the globality of instrument and good seal performance, be convenient to install.This plumb line coordinator has that measurement range is wide, resolution is high, measuring accuracy is high, without features such as electricity drift, automatic fault diagnosis, the non-contact measurements achieving real meaning.
2, structure is simple.
the present invention includes base plate, base plate is provided with guide rail, guide rail is provided with pole, pole is provided with pointolite, the other end corresponding with pointolite on base plate is provided with baffle plate, and the middle part of baffle plate is provided with lens, and what the rear side of baffle plate was corresponding with baffle plate is provided with dash receiver, dash receiver is provided with circuit board, circuit board is provided with CCD device; Mark is provided with between baffle plate and dash receiver.Component is few, therefore says that structure of the present invention is simple.
Accompanying drawing explanation
for technical matters solved by the invention, technical scheme and beneficial effect are clearly understood, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
fig. 1 is structural representation of the present invention.
1 be dash receiver, 2 be CCD device in figure, 3 be mark, 4 be baffle plate, 5 be lens, 6 be guide rail, 7 be pole, 8 be pointolite, 9 for base plate.
Embodiment
as shown in the figure, the present invention includes base plate 9, base plate 9 is provided with guide rail 6, guide rail 6 is provided with pole 7, pole 7 is provided with pointolite 8, the other end corresponding with pointolite 8 on base plate 9 is provided with baffle plate 4, the middle part of baffle plate 4 is provided with lens 5, what the rear side of baffle plate 4 was corresponding with baffle plate 4 is provided with dash receiver 1, dash receiver 1 is provided with circuit board, circuit board is provided with CCD device 2; Mark 3 is provided with between baffle plate 4 and dash receiver 1.
described CCD device 2 adopts CZ type CCD plumb line coordinator.
the core technology of CZ type CCD plumb line coordinator is the optoelectronic integration displacement transducer adopting liner CCD image sensor to be developed to.This sensor transmits flag-rod by source of parallel light, displacement and is made up of liner CCD image sensor and integrated photelectric receiver three part of peripheral circuit.Wherein, the resolution of sensor is determined by the width of the pixel of liner CCD image sensor, has the different class such as 14 μm, 7 μm, 4 μm.Once after have selected the model of liner CCD image sensor, the measuring accuracy of sensor then depends primarily on the quality of source of parallel light.Generally speaking, the quality of source of parallel light depends primarily on Lens Design and the processing technology of source of parallel light.By the optical design calculation and test of source of parallel light, have employed the design proposal of Large visual angle compound lens, while making the directional light visual field of compound lens meet sensor measurement scope needs, also meet the needs of sensor to nonlinear measurement error criterion.
above content is the further description done the present invention in conjunction with concrete preferred implementation; can not assert that specific embodiment of the invention is confined to these explanations; for general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; some simple deduction or replace can also be made, all should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
