Description

Reflective prism with instruction light source
Technical field
The utility model relates to a kind of engineering surveying instrument, especially a kind of reflective prism with instruction light source.
Background technique
In current engineering survey, generallys use total station and is measured with the mutually matched mode of reflective prism, Total station is set up in survey station, reflective prism is set up in tested point, the geometry of reflective prism is sighted by using total station Center determines the position of tested point, to obtain required data.It, often need to be by flashlight when measurement environment is darker Equal external light sources carry out necessary illumination to reflective prism, can just measure.
There is defects for such measurement method, when measuring the environment necessary illumination of shortage, although with external light source to anti- The formula prism of penetrating is illuminated, but due to measuring point at a distance from survey station usually farther out, the illumination zones of the light sources such as common flashlight compared with Small and the apparent feature of shortage, observer are difficult to quickly find the position of reflective prism in the visual field of total station, it is even more impossible to The geometric center of prism is accurately sighted, is made troubles for measurement work.
Summary of the invention
In order to overcome existing engineering measuring technology measure environment it is darker when need to use external light source irradiation prism, be difficult to The defects of finding the position of reflective prism in the visual field and can not accurately sighting the geometric center of reflective prism, this is practical new Type provides a kind of reflective prism with instruction light source, described to indicate light source by the directional light sources of guide observer's observed direction It is formed with the positioned light source of supplementary observation person's alignment prism geometric center.By means of referring to possessed by this reflective prism itself Show light source, observer need not use external light source in the environment of lacking illumination, can also quickly find the position of reflecting prism And its geometric center is accurately sighted, it offers convenience for measurement.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of reflective rib with instruction light source Mirror, including backboard, camera lens, five part of directional light sources, positioned light source and power supply circuit.The backboard is the fillet square of downside hollow out Shape plate, with tow sides, front is for fixed lens and instruction light source, and reverse side is for power supply needed for connecting instruction light source Circuit.The camera lens is fixed on the positive center of backboard, measures for reflecting the laser beam of total station sending.It is described Directional light sources are composed in parallel by the light emitting diode of multiple capable of emitting green lights, are the cyclic annular light source of abutting lens edge, and each Diode is equally spaced embedded in the front of backboard.According to the difference of prism backboard size, the quantity of used diode is with 15 It is advisable to 25.When measurement environment is darker, due to the ring of light that directional light sources are green, there is unique color and form, Readily identified and confirmation in the total station visual field, to realize the purpose for being quickly found out and substantially sighting reflecting prism.The positioning Light source is the ribbon light source composed in parallel by the light emitting diode of multiple capable of emitting yellow lights, is located at the horizontal and vertical of camera lens On axis, each diode is also equally spaced embedded in the front of backboard and the extended line of positioned light source passes through in the geometry of camera lens The heart.According to the difference of prism backboard size, be advisable using the quantity of diode with 5 to 10.In the thin standard of rotation total station When burnt spiral and alidade are to be finely adjusted, can enable horizontal direction in the visual field crosshair first move in the horizontal direction, make its by It walks close to vertically oriented light source, when the crosshair of vertical direction is overlapped with vertically oriented light source, then adjusts horizontal direction cross Silk is overlapped with horizontal location light source, that is, completes the fine sight to prism geometric center.The power supply circuit is sequentially connected by conducting wire It connects directional light sources, positioned light source, battery case, switch enclosure to be formed, route protection set is enclosed in the outside of conducting wire, to avoid electricity Damage of the road by external environment.
The above-mentioned reflective prism with instruction light source, the light emitting diode are traditional chemical type light emitting diode, It should have stable forward drop and positive operating current, and need to first connect flows resistance that a resistance value is 5 Ω again into Row is in parallel, so that the electric current of each diode in parallel be made to obtain an equitable breakdown, avoids damage element.
The above-mentioned reflective prism with instruction light source, the battery case are located at backboard reverse side upper right side, can load One section No.5 cell provides electric energy as power supply, instruction light source positive to backboard.
The above-mentioned reflective prism with instruction light source, the switch enclosure are located at the lower right of battery case, are one It is connected to the push-button switch of current-limiting resistance, it is convenient to the on-off of circuit where controlling light source.Current-limiting resistance needed for calculating When resistance value, the difference of supply voltage Yu light emitting diode forward drop need to be first calculated, then calculate the same light emitting diode of this difference The ratio between positive operating current, thus the minimum resistance value for the circuit safety that is guaranteed, then choose closest to and slightly larger than minimum resistance The resistance of value is as current-limiting resistance.
The above-mentioned reflective prism with instruction light source, the route protection set are thinner silica gel hose, package Conducting wire outside and be fixed on the top of backboard reverse side and avoid it by external environment for protecting the complete of circuit of light sources Damage.
It is indicated as composed by orientation and positioned light source the utility model has the beneficial effects that the utility model prism has Light source, directional light sources have unique color and shape, and are positioned next to camera lens, measure environment it is darker when can make observer by The position transition of traditional searching prism is to find the directional light sources with obvious color and shape, thus being not necessarily to external light source In the case where sight prism camera lens rapidly.After observer substantially alignment prism camera lens, it is accurate that positioned light source can be used as observer Important references when traversing head geometric center, by the positioned light source of horizontal and vertical both direction, observer is at most only needed Adjust total station twice, can fine sight camera lens geometric center, thus measurement when substantially reducing ambient lighting deficiency Error.
