Can conveniently adjust the leveling device of observed range
The utility model belongs to field of measuring technique, relates in particular to a kind ofly to reduce survey crew labour intensity, increase work efficiency, and can conveniently adjust the leveling device (spirit-leveling instrument and scale) of observed range.
At present, traditional leveling device is comprised of a spirit-leveling instrument and two levelling staffs.During measurement, first by staffman, two levelling staffs are placed in respectively to ground A, B 2 points, again spirit-leveling instrument is arranged on to the centre position of 2 of A, B, surveyor utilizes the horizontal line of sight of the rear spirit-leveling instrument of leveling to sight respectively the absolute altitude numerical value that reads two levelling staffs, the difference of the high numerical value of institute's mark is the height differences by leveling of 2 of ground A, B, if known elevation wherein, can be extrapolated by the discrepancy in elevation elevation of another point.Because factors such as being subject to Instrument Manufacturing Technique, atmospheric environment and surveyor affects, between the telescope collimation axis while making to observe (line of crosshair intersection point and object lens photocentre) and surface level, there is an angle,
ithe size at angle directly has influence on precision and the reliability of measurement of the level.In order to eliminate
ithe impact of angle etc. and distance dependent factor, guarantee measurement of the level precision, in operation, require spirit-leveling instrument to equate apart from the horizontal range of two levelling staffs.The deficiency existing in actual job is: two staffman are walked and roughly kept spirit-leveling instrument to equate apart from the horizontal range of two levelling staffs by artificial amount, then surveyor is again according to the reading of three range findings of spirit-leveling instrument, by propagandaing directed to communicate, gesture, intercom etc. notify staffman to adjust levelling staff apart from the distance of spirit-leveling instrument, inefficiency.Especially in complicated terrain environment or under compared with atrocious weather condition, realize the equidistant configuration between spirit-leveling instrument and levelling staff, often expend a large amount of energy and time of survey crew, affect the work efficiency of measurement of the level.
Summary of the invention
The utility model is in order to solve the existing above-mentioned technical matters of prior art, provides a kind of and reduces survey crew labour intensity, increases work efficiency, and can conveniently adjust the leveling device (spirit-leveling instrument and scale) of observed range.
Technical solution of the present utility model is: a kind of leveling device that can conveniently adjust observed range, there are spirit-leveling instrument and levelling staff, described spirit-leveling instrument is provided with housing, at housing, be provided with level outward, in housing, be provided with successively object lens, focusing component, automatic horizontal sight line compensator, spectroscope, crosshair graticule and eyepiece, be provided with CCD module corresponding to spectroscope, the output of CCD module is joined by data processing module and single-chip microcomputer, is connected to the first communication unit and the first aobvious control terminal with single-chip microcomputer; Described levelling staff is provided with second communication unit, second communication unit and the second display terminal and joins.
The utility model is on traditional spirit-leveling instrument and levelling staff, to be equipped with display terminal and communication unit, realized spirit-leveling instrument automatically reporting in real time to information such as distances between levelling staff, staffman can show and voice message according to aobvious control terminal, accurate adjustment levelling staff is to the distance of spirit-leveling instrument in real time, the communication exchange links such as voice loaded down with trivial details between surveyor and staffman and gesture have been reduced, can reduce survey crew labour intensity, improve the work efficiency of measurement of the level.

Fig. 1, the 2nd, the structural representation of the utility model embodiment 1.
Fig. 3 is the circuit diagram of the utility model embodiment 1.
Fig. 4 is the use constitutional diagram of the utility model embodiment 1.
As shown in Figure 1, 2, 3: be provided with hollow shell 1 that metal, fiberglass etc. make, outside hollow shell 1, be provided with level 2, in hollow shell 1, be provided with successively object lens 3, focusing component 4, automatic horizontal sight line compensator 5, spectroscope 6, graticule crosshair 7 and eyepiece 8, be provided with CCD module 9 corresponding to spectroscope 6, the output of CCD module 9 is joined by data processing module 10 and single-chip microcomputer 11, is connected to the first communication unit 12-1 and the first aobvious control terminal 13-1 with single-chip microcomputer 11; Described levelling staff 20 is provided with second communication unit 12-2, and second communication unit 12-2 and the second display terminal 13-2 join.The first communication unit 12-1 and second communication unit 12-2 all adopt bluetooth communication, or the wireless radio-frequency communication module identical with intercom transceiver module principle, or the GSM identical with mobile phone principle or cdma wireless communication module, or adopt bluetooth communication and GSM or cdma wireless communication module.
The embodiment 1 application course of work:
As shown in Figure 4:
(1) first staffman is positioned over A measurement point by first measurement of the level scale 20, makes it firm;
(2), at B point place, surveyor uses auxiliary stand 30 to settle spirit-leveling instrument, by regulating the relevant spiral on auxiliary stand 30 to make level 2 bubbles placed in the middle, object lens 3 are sighted to first levelling staff 20, then by aobvious control terminal 13-1, control the focusing screw in focusing component 4, make the delineation of first levelling staff 20 reach clear state, utilize CCD module 9 automatically to read three altitude informations of corresponding first levelling staff, by data processing module 10, calculated height and the A of measurement of the level, distance between B, simultaneously by the A calculating, range data between B transfers to first by the transmitting in real time of the first communication unit, second communication unit 12-2 on second measurement of the level scale 20 and the second display terminal 13-2.
(3) second staffman is according to the distance between the A receiving, B, by equidistant principle, select suitable C point to settle second measurement of the level scale 20, now, spirit-leveling instrument surveyor sights second levelling staff 20 by object lens 3 and observes, and real-time the second display terminal 13-2 that range data between the B calculating, C is reached to second measurement of the level scale 20, second staffman contrasts the range difference between B, C and between A, B, further adjust C point position, finally make distance between B, C equal the distance between A, B.
(4) by above-mentioned steps, can draw the height differences by leveling between A, C.Now, if carry out continuous measurement of the level, second staffman settles second measurement of the level scale 20 motionless at C point, and spirit-leveling instrument surveyor will move and settle spirit-leveling instrument according to actual landform, and then repeating step (1) ~ (3).
