Description

The fixed composite level of high precision
Technical field
The utility model belongs to field of measuring technique, relate in particular to a kind of simple in structure, cost is low and can effectively improve the fixed composite level of high precision of leveling work efficiency and precision.
Background technology
Traditional leveling device is comprised of a spirit-leveling instrument and two levelling staffs.During measurement, first 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, after utilizing leveling, the telescopical horizontal line of sight of spirit-leveling instrument is sighted 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.The deficiency existing is: (1) surveying work efficiency and reliability are low.The reasonable disposition that realizes position between spirit-leveling instrument and levelling staff in complicated terrain environment at 3, often expends a large amount of energy and time of survey crew, and efficiency is measured in impact; (2) measure and be subject to terrain environment restriction.When running into the complex-terrain environment such as abrupt slope, hollow, pool, irrigation canals and ditches, gully, rivers, mountain area, often spirit-leveling instrument can not be erected to the centre position of two levelling staffs, cause measurement of the level to implement.
In order to overcome above-mentioned deficiency, number of patent application is 201210466871.3 Chinese invention patent, a kind of " chi instrument unification composite level for dual formula observation " (hereinafter to be referred as composite level) disclosed, its structure is to be provided with cylindricality chi body and level, on the same cylinder of cylindricality chi body, be fixed with the levelling staff parallel with cylindricality chi body axis and the observing unit that can slide up and down, described observing unit has the other side's altitude signal analyzer and the our altitude signal analyzer being mutually permanently connected, the collimation axis of the other side's altitude signal analyzer is vertical with cylindricality chi body axis.Its measuring method has the following steps: two composite levels are placed in respectively to ground A, B 2 points, synchronously slightly flatten, mutually sight, synchronous finishing is flat, equity observation, two-way checking and data processing, can obtain the height differences by leveling of 2 of ground A, B.Use composite level can really realize point-to-point direct levelling, without the reasonable disposition of considering traditional spirit-leveling instrument and levelling staff positional distance with wasting time and energy, simultaneously also because the reliability of pair observations system checks, no longer need to come and go and measure, improve work efficiency and the reliability of measurement of the level, can under the complex-terrain environment such as abrupt slope, hollow, pool, irrigation canals and ditches, gully, rivers, mountain area, implement measurement of the level easily.
Yet the deficiency that above-mentioned patented claim exists is:
1. to guarantee that observing unit can slide up and down, conventionally slideway, slide block device need to be set, and observing unit slides up and down, not only need the other side's altitude signal analyzer, essential setting in order to determine the our altitude signal analyzer of we's height also, complex structure, cost are high;
2. observing unit slides up and down, need to constantly with our altitude signal analyzer, to the oneself height of observing unit, measure in real time, not only reduce the work efficiency of measurement of the level, and can sight because observing unit is difficult to accurately leveling, reduced measuring accuracy.
Summary of the invention
The utility model is in order to solve the existing above-mentioned technical matters of prior art, provide a kind of simple in structure, cost is low and can effectively improve the fixed composite level of high precision of leveling work efficiency and precision.
Technical solution of the present utility model is: the fixed composite level of a kind of high precision, be provided with cylindricality chi body, levelling staff, level, handle and observing unit, described observing unit is all first the other side altitude signal analyzer and second the other side altitude signal analyzers vertical with cylindricality chi body axis of collimation axis, the upper end of first the other side's altitude signal analyzer and cylindricality chi body is fixedly connected, and the lower end of second the other side's altitude signal analyzer and cylindricality chi body is fixedly connected.
On described cylindricality chi body, be also provided with the digital signal processor joining with first the other side's altitude signal analyzer and second the other side's altitude signal analyzer, output signal and the data transmission unit of digital signal processor join.
The utility model being provided with is separately fixed at first the other side's altitude signal analyzer and second the other side's altitude signal analyzer at the upper and lower two ends of cylindricality chi body, compared with prior art, meet range needs, the devices such as slide construction (slide rail, slide block etc.) and our altitude signal analyzer have been omitted again, and without constantly the oneself height of observing unit being measured in real time with our altitude signal analyzer, have simple in structure, cost is low, can effectively improve the advantages such as leveling work efficiency and precision.
