Description

Electronic theodolite

Technical field

The present invention relates to a kind of electronic theodolites.

Background technology

Electronic theodolite can be widely applied to the three of countries and cities, four etc. triangles control measure, for railway, highway, The engineering survey of bridge, water conservancy, mine etc., it can also be used to build, the installation of large scale equipment, be applied to cadastration, Shape measures and various engineering measures.Because needing special training in some Engineering Majors, to adapt to the needs of industry.

As shown in Fig. 3, what Fig. 3 was indicated is telescope sights in component camera lens on electronic theodolite the visual field, in camera lens Silk be crosshair, read to run-home, in order to measurement angle, the number angle of visibility angle value of reading.

In engineering survey, the crosshair in the camera lens in electronic theodolite is needed to be directed at line rod (by another staff Hold in target location, be line rod red and white), and require the vertical hair mariages (middle and lower parts Fig. 3) of crosshair by line rod It is clipped in the middle.

In teaching either in practical operation student or apprentice often because can not correctly grasp the position of aiming and nothing Method observes correct numerical value.Thus, it is necessary to a kind of realization helping its study is provided for beginner, is imparted knowledge to students so as to improving Accuracy of observation in quality and engineering survey.

Invention content

Therefore, the purpose of the present invention is to provide a kind of electronic theodolites, and beginner is contributed to grasp electronic theodolite It uses, the accuracy of observation in being measured so as to nuclear engineering of improving the quality of teaching.

A kind of electronic theodolite, including pedestal and the alidade that is installed on pedestal, and the prestige on alidade Remote mirror, it is axisymmetric on the basis of installing the position of telescope by telescope axis on alidade to be equipped with a pair of of laser range finder, It matches each laser range finder and is equipped with the driving mechanism of adjustment its axis and telescope axis angle, and drive the driving mechanism Fine motion knob.

From the above as can be seen that configuring a pair of of laser range finder on the electronic theodolite of conventional structure, and two swash Optar is configured about the axis for axis symmetry of telescope, and when two laser range finders are all directed at line rod, institute's ranging is from should one It causes, shows the appropriate location that line rod falls into the telescope visual field with this condition, thus, pass through the readable of laser range finder Property, it can effectively assess whether telescope has observed correct numerical value.It in turn, can be with by the auxiliary of laser range finder It effectively improves the quality of teaching, allows the correct number reading method of the grasp of student or apprentice quickly, and advantageously ensure that observation essence Degree.

Above-mentioned electronic theodolite, two laser range finders output one comparator of connection, and comparator then connects a driver, drives Dynamic device then connects warning device.

Above-mentioned electronic theodolite, the warning device are a loud speaker.

Description of the drawings

Fig. 1 is a kind of structural schematic diagram of electronic theodolite according to the present invention.

Fig. 2 is a kind of functional block diagram of electronic theodolite according to the present invention.

Fig. 3 is that a kind of electronic theodolite telescope sights the cyclogram in component camera lens.

In figure：1. centralizer eyepiece, 2. alidades, 3. laser range finders, 4. fine motion knobs, 5. microscope bases, 6. adjust Focus knob, 7. telescope oculars, 8. control panels, 9. level meters, 10. benchmark foot screws.

Specific implementation mode

About laser range finder 3, the range capability of current small-sized laser range finder 3, which is fully able to meet engineering, to be powered on The use distance of sub- theodolite, and the volume for having the laser range finder of corresponding range capability is very small, on electronic theodolite Configuration occupied by space it is not too large.

About alidade 2, refers to the entire shell and inner body of the rotation of electronic theodolite vertical pivot, be electronic theodolite The middle maximum component of volume, inner space is bigger, disclosure satisfy that the installation such as laser range finder 3 and the configuration of driving structure.

Referring to attached drawing 1, in Fig. 1, electronic theodolite lower substrate is omitted, only embodies benchmark foot screw 10, is furnished with three It is a, it is configured at equilateral triangle, and level meter 9, generally air-bubble are equipped on upper the supported component of benchmark foot screw 10 Level, it is simple in structure.

Laser range finder 3 is further related to, range error is very small, by two configurations of laser range finder 3 in telescope Both sides, there is telescope ocular 7, microscope base 5 to be limited in Fig. 1, axis shaft pair of two laser range finders 3 about telescope Claim arrangement, thus when two laser range finders 3 are all directed at line rod, if the accuracy of reading of telescope, two laser range finders Registration should be consistent, if inconsistent, shows that electronic theodolite is not adjusted, so as to provide intuitive reference to student.

Driving mechanism about fine motion adjustment, it should be understood that in precision instrumentation, fine motion adjustment is a kind of conventional tune It is whole, such as microscope, theodolite, mechanical electronic theodolite must configure the adjustment mechanism of fine motion, to ensure measurement and positioning Accuracy.

Thus, about the aiming of laser range finder 3, first the case where telescope has arrived rough location on alidade 2 Under, so that it may to go for line rod by the fine motion of laser range finder 3 adjustment.

Since ranging distance is different, laser range finder 3 and the angle of telescope axis will be different, certainly this folder Angle is very small, changes also smaller, the just mechanical adjusting mechanism use of suitable fine motion.

Laser range finder 3 is relative to other rangefinders, and for ultrasonic distance measuring apparatus, precision wants much higher, and by joyous Meet factor influence it is smaller, if the variation of ultrasonic distance measuring apparatus, environment temperature will produce larger error, and light then will not be by this shadow It rings.

Digital display module on laser range finder 3 can contribute to directly read, to help student to correct electronic theodolite Use.But observation also can be by large effect, to influence the normal use of student.For this purpose, for two laser range finders 3, the mode for comparing output may be used, directly alarmed by sound, light or other modes, the control plane as shown in Fig. 1 Plate 8 can generally also configure display screen on control panel, can be exported to result.

Laser range finder 3 is generally equipped with serial ports output interface, and output is digital quantity, it should be understood that laser range finder 3 What is itself directly generated is analog quantity, is the digital quantity generated by analog-to-digital conversion module, can be to swashing when configuring comparator Optar 3 is transformed, to which comparator is directly connected to the output of the analog quantity circuit unit of laser range finder 3, directly Comparison result is generated, sound-light alarm is generated.

In some simple applications, loud speaker may be used in warning device, simple in structure, at low cost, and can understand Carry out alarm.
