Abstract
Disclosed is an electronic level, relating to a level, which solves the problems that the present level can not be used when the light is deficient or dark and the blind can not use the level either. The level comprises a level body, a laser shooting device on the level body, a power supply, a switch, a signal processing device and a signal indication device, which are all connected by data wires and conductive wires. The signal processing device comprises an illuminating source, a leveling instrument, two light sensors and a signal processing module. The illuminating source and the light sensors are respectively installed at both sides of the leveling instrument. The signal indication device consists of a signal receiver and a switch. The light sensor receives light signal and the light signal is processed by the signal processing module, and then the light signal is transferred to the signal indication device through the data wires. The level has the advantages of convenient use and accurate measurement.
Description
Technical field
The utility model relates to a kind of surveyor's staff, relates in particular to a kind of telltale on the surveyor's staff.
Background technology
The laser level chi is not only time saving and energy saving with respect to traditional surveyor's staff, and the precision of measuring is guaranteed, has improved work efficiency greatly, is used widely at finishing, building field.Judge at present the laser level chi whether level mainly rely on the air level of estimating on the level whether balance judged, but when not seeing Chu's air level, just be difficult to judge, such as just being not suitable for using in the relatively dark place of insufficient light, and present surveyor's staff is not suitable for the blind person and uses.
Summary of the invention
Goal of the invention of the present utility model is can use under the light normal condition in order to overcome the defective of above-mentioned prior art, to provide a kind of, also can use in the relatively darker place of insufficient light, and the surveyor's staff of suitable blind person use.
The novel technical scheme of this use is: a kind of electronic horizontal ruler, comprise the chi body, laser beam emitting device on the chi body, power supply, switch, level, signal processing apparatus, signal indicating device are formed, signal processing apparatus is made up of light source, level, two light sensors and signal processing module, and light source and light sensor are installed in the level both sides respectively; Signal indicating device is made up of signal receiver and switch, and light sensor receives light signal after signal processing module is handled, and is transferred to signal indicating device by data line.
Described two light sensors lay respectively on the light emitted angle.
Bubble on the level is positioned at the light emitted angle.
Described signal receiver is a signal lamp.
Described signal receiver is a hummer.
Described signal receiver is signal lamp and hummer, and described switch is a change-over switch.
Described light source is a light emitting diode.
A kind of electronic horizontal ruler by the technique scheme manufacturing, come the level of judgment rule body in the ordinary course of things by the level on the chi body, also can come whether balance of determined level chi in the relatively dark place of insufficient light by the indicator signal device, and the blind person also can use, have easy to usely, measure advantage accurately.

Embodiment
Below in conjunction with Fig. 1, Fig. 2, Fig. 3 embodiment of the present utility model is described in detail.
A kind of electronic horizontal ruler, comprise chi body 1, the laser beam emitting device 2 of chi intracoelomic cavity, power supply, signal processing apparatus 3 and signal indicating device, the horizontal level 7 of chi surface is formed with vertical level 8, laser beam emitting device 2, power supply, connect by data line between signal processing apparatus 3 and the signal indicating device, signal processing apparatus 3 is by light source 17, level 15, left side light sensor 12, right light sensor 14 and signal processing module 16 are formed, described light source 17 is a light emitting diode, light emitting diode, left side light sensor 12 and right light sensor 14 are installed in level 15 both sides respectively, left and right sides light sensor 12,14 lay respectively on light source 17 emission angle, and light source 17 emission line just in time with level 15 in bubble 13 both sides tangent.Signal indicating device is made up of signal receiver and change-over switch 5.Signal receiver comprises hummer 4 and signal lamp 6, and wherein signal lamp 6 comprises 9,11 and green signal lights of two signal red lights, 10 compositions.Left and right sides light sensor 12,14 receives light signal after signal processing module 16 is handled, and is transferred to signal indicating device by data line.
When level 15 is in horizontality, bubble 13 in the level 15 is in center position, light source 17 is radiated on the bubble 13 of level 15, be installed in level 15 next doors about two light sensors 12,14 receive the identical signal of intensity, and signal is passed to signal processor 3.If change-over switch 5 switches on the signal lamp 6, after then signal processor 3 is handled signal is presented on the signal lamp 6, green light 10 is bright, and two red lights 9,11 do not work.If switch to hummer 4, then hummer 4 does not pipe.
When level 15 is not in horizontality, bubble 13 in the level 15 is not in center position, light source 17 is radiated on the bubble 13 of level 15, light sudden change liquid, the gaseous state critical conditions make be installed in level 15 next doors about two light sensors 12,14 be subjected to the different signal of intensity, and signal is passed to signal processor 3.If change-over switch 5 switches on the signal lamp 6, after then signal processor 3 is handled signal is presented on the signal lamp 6, red light is just bright, and wherein red light 9 is bright, is exactly that bubble 13 is taken back, and chi body 1 left side is higher; Red light 11 is bright, is exactly that bubble 13 takes over, and chi body 1 the right is higher.If switch to hummer 4, then hummer 4 pipes.
Bubble 13 should be positioned at light source 17 emission angle in the above-mentioned level 15, and light source 17 emission line just in time with level 15 in bubble 13 both sides when tangent acknowledge(ment) signal the most accurate.
