Description
Technical field
The present invention relates to engineering survey field, be specifically related to oneDay and night accurate measurement levelling rod。
Background technology
The work measuring ground point elevation is called the measurement of higher degree, it is widely used in engineering survey, commercial measurement and geodesic survey etc. owing to the certainty of measurement of the measurement of the level is of a relatively high at present, the principle of the measurement of the level is the reading that the horizontal line of sight utilizing level gauge to provide reads on the levelling rod being erected at 2, by calculating the discrepancy in elevation measuring point-to-point transmission, further according to known point grid DEM point to be located elevation.Principle asAccompanying drawing 1Shown in.The level gauge applied at present can be divided into optical level and electronic level by principle, wherein electronic level is to add the parts such as spectroscope and Electro-Optical Sensor Set (C (3) array) in instrument telescope light path, adopts bar code graduation levelling rod and image procossing electronic system to constitute light, mechanical, electrical and that information storage is integrated with process leveling systems.The aid that electronic level generally adopts when measuring is levelling rod and foot pin, adopts following 3 kinds of autoelectrinic number reading methods measurement method of correlation, geometric method and phase method simultaneously.Electronic level has that measuring speed is fast, reading is objective, labor intensity is little, homework precision is high, measurement data is easy to input computer and easily realizes measurement of the level inside and outside trade integration feature and be widely used.But simultaneously electronic level also exists the illuminance to levelling rod and requires high shortcoming when reading, relatively low in illuminance, light is uneven or cannot reading in hypographous situation on bar code ruler.In real work, part is measured work and is necessarily required to carry out under night-environment such as the high-acruracy survey of the settlement observation of Urban Underground rail track, overhead railway, and requires, owing to vibrations that daytime, vehicle produced make certainty of measurement reduce, bridge moving static test and the settlement of highway observation etc. that carry out under vehicle at night rareness environment.Owing to illumination condition at night does not often reach requirement, cause that level gauge None-identified goes out the bar code on levelling rod；Simultaneously in actual measurement process, levelling rod must move, and when distance level gauge farther out time, adopt the lighting system of powerful lighting or pocket lamp to be unsuitable for observation.The existing part levelling rod illuminator in market, but use dismounting complex every time, chi face there is is impact, uses inconvenience.
Summary of the invention
For solving the problems referred to above, the invention provides oneDay and night accurate measurement levelling rod, illuminator is built in precise levelling rod, greatly facilitates use.
For achieving the above object, the technical scheme that the present invention takes is:
Day and night accurate measurement levelling rod, including levelling rod body, luminescent lamp strip, spirit level illuminating lamp, on-off circuit and power supply, described levelling rod body is the back side precise levelling rod equipped with bubble type, described luminescent lamp strip is built in the blade of bar code side of levelling rod body, spirit level illuminating lamp is composited by spirit level and illuminating lamp, described illuminating lamp is single LEDs high brightness LED, it is arranged on the surface of the chi spirit level behind of levelling rod body, control switch in on-off circuit is toggle switch, toggle switch is arranged on the behind of levelling rod body, described power supply is connected with luminescent lamp strip and spirit level illuminating lamp by on-off circuit.
Preferably, described power supply adopts lithium battery, is arranged in the battery flat below the spirit level of levelling rod body, can be taken off charging, charging system public with electronic level, makes the illuminator working time reach a day of working at night more than.
Preferably, described luminescent lamp strip is made up of the LED light emitting diode parallel connection of high brightness, replaceable.
Preferably, described spirit level illuminating lamp is upper and lower two.
Preferably, luminescent lamp strip is two, lays respectively at bar code both sides, front.
The method have the advantages that
(1) namely the present invention can be used for electronic leveler measurement on daytime, can be used for again the measuring levelling rod of electronic leveler at night, due to internal illumination device on the basis of levelling rod, overcome levelling rod shortcoming of None-identified bar code under the environment that illuminance is unstable or low so that measure night little with temperature Change, affected little by atmospheric refraction light and by driving, vibration influence is little, the advantage that can farthest improve measurement of the level precision when road is measured night.
(2) present invention can make electronic level work in the environment that light is more weak or mixed and disorderly better, owing to LED illumination lamp is built in levelling rod bar code, the illuminance of Gu Tiaomachu is very strong, and ambient light is substantially inoperative to the illumination zone of illuminating lamp plate.
(3) present invention is easy to use, simple, compares with original levelling rod, weight increase only 0.3 kilogram.
(4) present invention uses the workload that can be greatly reduced survey crew, improve work efficiency, owing to levelling rod adopts active lighting system, so that the sensitivity of electronic level identification bar code increases, largely shorten and measure the adjustment of work, correction time.
(5) power consumption of the present invention is low, longevity of service, and owing to power supply adopts lithium battery used by level gauge, highly versatile, buying is convenient, and it is convenient to change, and makes the illuminator working time can reach to work long hours.
