Description
Technical field
The utility model relates to fields of measurement, specifically relates to a kind of band vernier, and can free extracting ratio, free preset proportion, show the electronics engineer's scale of related data automatically.
Background technology
Engineer's scale is engineering staff's an indispensable instrument, and it can be measured on drawing and draw, for engineering mapping is provided convenience with actual size in the ratio of setting.
Engineer's scale of the prior art is made of the chi body that has scale, and this scale comprises two parts, and a part is actual scale, promptly with the scale of centimetre, millimeter demonstration; Another part is the scale after the conversion ratio, according to the proportionate relationship that this engineer's scale is set, and the scale after the demonstration conversion ratio.For example, a kind of 1: 200 engineer's scale, actual scale shows 1 centimetre, 2 centimetres, 3 centimetres ... show 200 centimetres, 400 centimetres, 600 centimetres in scale after 1: 200 corresponding conversion ratio ... like this, the user measures one section actual scale on drawing be 2.5 centimetres line segment, and the scale after the transformation of scale then will be shown as 500 centimetres.
Engineer's scale of the prior art, proportionate relationship is fixed, and the engineer's scale of a proportionate relationship can only could use under the demand of this proportionate relationship, if need the conversion proportionate relationship when using, needs is changed the engineer's scale of other proportionate relationships.Even the engineer's scale of Three Diamond also can only utilize its three hexagons, six kinds of proportionate relationships are provided at most, therefore, the proportionate relationship that engineer's scale of the prior art is limited can not satisfy the instructions for use of actual engineering mapping far away.
Engineer's scale of the prior art can only use under by the situation of mapping object scale relation known, and in the actual mapping operations, usually is not know to survey and draw under the background of object scale relation to launch, and at this moment, finishes the mapping operations very difficulty that will become.For example; in the real work; we usually can be in the face of a drawing of not printing by fixed proportion; the drawing enclose pattern is drawn by the actual ratio relation; as a residential area general layout; we know that wherein the actual range that certain section line is represented is 30 meters; but go to measure with gage; display scale is 13 centimetres; if we wonder that display scale is that how many rice one section space actual range of 31 centimetres is; then will need complicated computational process, engineer's scale of the prior art just can't have been offered help at all.
Engineer's scale of the prior art need be selected when reality is used, reading, calculating, and it is not too convenient to use, especially for many drawings of multiple proportionate relationship, and for failing the personnel of skilled usage ratio chi, application difficult; Simultaneously, the range estimation reading mode of engineer's scale of the prior art also cannot say for sure to demonstrate,prove mapping precision.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of electronics engineer's scale, this electronics engineer's scale is preset proportion relation arbitrarily not only, and can set multiple proportionate relationship, more can freely grasp proportionate relationship, applied widely, easy to use, promoted the convenience of mapping operations greatly, again and simple in structure, easy to implement.

Also be provided with supply unit to described electronics engineer's scale power supply.
Electronics engineer's scale with present embodiment is an example below, illustrates the multiple application of electronics engineer's scale of the present utility model under various mode of operations, and following at least several usages can be arranged:
Usage one: use as the standard rule body, this is a known technology, does not elaborate at this;
Usage two, set by certain fixed proportion after, use.As need use the time as 1: 600 engineer's scale, at first in setup unit, set, by mode key MODE, press letter key A key again, enter the ratio setting, press numerical key 6 and 00, set by setting key SET key again.This engineer's scale has just become an engineer's scale of 1: 600 like this, and at this moment, the ratio viewing area SCALE in the display unit shows 1: 600.Starting point is aimed at the end that requirement is surveyed target, and moving cursor is to the other end that measures target, at this moment, and the data after the data readings viewing area DATA in the display unit converts displaying ratio.Such as, measure 1 section 20 millimeters line segment, data readings viewing area DATA will show 12000.Setup unit can easily, very freely be set the needed various proportionate relationships of user, such as 1: 12, and 1: 40,1: 125 ... Deng, can satisfy the needs under any ratio, this is that engineer's scale of the prior art can't provide fully, promotes user's convenience greatly.
Usage three, use simultaneously as a plurality of engineer's scales.As in use, need under multiple proportionate relationship, to use, use the engineer's scale of 1: 500 and 1: 800 simultaneously as need, at first in setup unit, set, by mode key MODE, press letter key B key again, enter the multi-scale application model.Described in above-mentioned usage two, after pressing numerical key and setting 1: 500 proportionate relationship, press setting key SET and letter key A key again, this proportionate relationship of 1: 500 is set in the A key.Press setting key SET and B key again, this proportionate relationship of 1: 800 is set in the B key.At this moment, just had A key 1: 500 simultaneously, the engineer's scale of 1: 800 these two kinds of proportionate relationship of B key.Carry out the application under the ratio in 1: 500 in the A key during use, carry out the application under the ratio in 1: 800 in the B key.All application processes are identical with usage two, by moving of vernier, obtain accurate data readings in display unit.This application model will allow the user finish the complexity mapping operation under the multiple proportionate relationship with this one engineer's scale.
Usage four, use as the engineer's scale of free extracting ratio.This application is that engineer's scale of the prior art can't be accomplished fully, and usually allows the user be in the predicament of having no way of doing it in real work.For example: printed a plant area general layout, this drawing interior architectural applications relation is drawn in proportion, but often can't print by certain fixed proportion when printing, but it is very random, possible its proportionate relationship is 1: 725, and at this moment, engineer's scale of the prior art can't be used at all.The actual range of our known wherein any segment distance is 180 meters such as the length of knowing certain factory building, at this moment, presses the mode key MODE in the setup unit, presses letter key C key again, and freedom of entry grasps ratio mode.Starting point is aimed at an angle point of this factory building, moving cursor is to another angle point of this factory building, press the setting key SET key in the setup unit, at this moment, this engineer's scale has just become with the on all four engineer's scale of this drawing print scale, its ratio becomes 1: 725, like this, just can carry out various mapping operations under the proportionate relationship in this drawing accurately at this.This mode capabilities is the once innovation in the engineer's scale technological system, will promote the facility and the accuracy of mapping operation greatly.
The application of electronics engineer's scale of the present utility model is not limited only to above-mentioned several usage, and its expanded application is also very extensive, no longer sets forth in the present embodiment.
Above-mentioned specification and embodiment are for author content of the present utility model better is described; be not to be to restriction of the present utility model; those skilled in the art; in essential scope of the present utility model; the variation of making, remodeling, interpolation or replacement also belong to protection domain of the present utility model.
