Description

Composite level parametric measurement method
Technical field
The invention belongs to field of measuring technique more particularly to a kind of composite level parametric measurement sides for improving determination efficiency Method.
Background technology
At present, there are two kinds of traditional spirit level and composite level applied to the equipment of the measurement of the level.
The characteristics of traditional spirit level is the separation of ruler instrument, is used cooperatively by a spirit level and two levelling staffs.During measurement 2 points of A, B first two levelling staffs being respectively placed on ground, then spirit level is arranged on to the centre position of 2 points of A, B, profit Sight the absolute altitude numerical value for reading two levelling staffs, the high numerical value of institute's mark respectively with the horizontal line of sight of spirit level telescope after leveling Difference be 2 points of ground A, B height differences by leveling.Deficiency existing for traditional spirit level is:(1)Measure working efficiency and reliable Property is low.The reasonable disposition of position between 3 points of spirit level and levelling staff is realized in complicated terrain environment, often expends and surveys The a large amount of energy and time of amount personnel, influences measurement efficiency.(2)Measurement is limited by terrain environment.When encounter abrupt slope, hollow, Pool, irrigation canals and ditches, gully, rivers, mountain area tend not to spirit level being erected at two levelling staffs when complicated landforms environment Centre position causes the measurement of the level that can not implement.In order to overcome the shortcomings of traditional spirit level, application No. is 201220611636.6 Chinese patent disclose a kind of " ruler combinative/compositwater water level for dual type observation "(Abbreviation composite level).Compound level Instrument structure is provided with cylindricality ruler body and spirit level, is fixed on the same cylinder of cylindricality ruler body parallel with cylindricality ruler body axis Levelling staff and the observing unit that can slide up and down, the observing unit have the other side's height finder and this being mutually permanently connected Square height finder, the collimation axis of other side's height finder are vertical with cylindricality ruler body axis.Other side's height finder is to look in the distance Mirror, and our height finder can be pointer, macro head, laser or infrared distance measuring device and absolute type linear grating etc.. Compared with traditional spirit level, the use of composite level is truly realized point-to-point direct levelling, improves level The working efficiency and reliability of measurement, and the reconnaissance of the measurement of the level, layout is not limited by terrain environment, it can be easily steep Implement the measurement of the level under the complicated landforms environment such as slope, hollow, pool, irrigation canals and ditches, gully, rivers, mountain area.Need two are compound during measurement Spirit level pairing uses and it is necessary to accurate determining instrument parameter:Height of instrumentIt is and remainingiAngle.
In order to coordinate the use of composite level, the Chinese invention patent of Patent No. 201310049994.1 " is suitable for The leveling measuring method of composite level " discloses how and measures the remaining i angles of correction composite level, how to correct and disappear The methods of except influence of the remaining i angles to measured value, however, there is following deficiencies for this method:(1)If it is mark directly with pointer Note measures our height, then on the one hand because being difficult to accurately determine other side's height finder by scale(Telescope)Collimation axle position It puts there are error, another aspect is also influenced by our zero point of scale difference;(2)According to macro head, laser or infrared The vertical electrotape such as ranging, absolute type linear grating obtains we's height, not only of high cost, but also there is with looking in the distance The installation matching error of mirror collimation shaft position, the equally influence there is also our zero point of scale difference.In order to overcome above-mentioned deficiency, Shen Please number be 201410585033.7 Chinese invention patent " composite level we Height Test method ", disclose measure we Altitude information and the improved method at composite level residue i angles, directly enhance determining instrument parameter(That is height of instrumentAnd It is remainingiAngle)Precision.However, it is found in the application practice of composite level:The instrument parameter measure side of above-mentioned patent application Method, which is both needed to switch type measurement twice, could complete to measure, and time-consuming and laborious, determination efficiency is low.
Invention content
