It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
It in addition, the technical solution between each embodiment can be combined with each other, but must be with ordinary skill
Based on personnel can be realized, this technical side will be understood that when the combination of technical solution appearance is conflicting or cannot achieve
The combination of case is not present, also not within the protection scope of the requires of the utility model.
The utility model proposes a kind of laser-measured height devices.
Referring to Figures 1 and 2, in an embodiment of the utility model, which includes fixed plate 3 and setting
Light source assembly 1, photomoduel 8 and laser sensor 4 in fixed plate 3, the light source assembly 1 are arranged in the fixed plate 3
Lower ora terminalis, the upper end of the fixed plate 3 is arranged in the photomoduel 8, and the photomoduel 8 is located at the light source assembly
Surface, the rear side of the fixed plate 3 is arranged in the laser sensor 4, by the laser sensor 4 to dispensing height
Monitoring is measured, the photomoduel 8 carries out capture to PCB dispensing.
When laser sensor works, laser pulse is first emitted by laser emitting diode alignment target.After target reflects
Laser is scattered to all directions.Some scattered light returns to transducer receivers, is imaged onto avalanche optoelectronic after being received by optical system
On diode.Avalanche photodide is the optical sensor that a kind of inside has enlarging function, thus it can detect it is extremely micro-
Weak optical signal, and it is translated into corresponding electric signal.Its principle is identical as radio radar, and laser alignment target is sent out
After being shot out, its two-way time is measured, obtains round-trip distance multiplied by the light velocity.Since laser has high directivity, Gao Dan
The advantages that color and high power, these are for surveying signal-to-noise ratio that is remote, determining target bearing, improve reception system, guaranteeing to survey
Accuracy of measurement etc. is all very crucial, therefore laser range finder is paid more and more attention.Grow up on the basis of laser range finder
Laser radar can not only ranging, but also target bearing, fortune fortune velocity and acceleration etc. can be surveyed, be successfully used to artificial defend
The ranging and tracking of star, for example, by using the laser radar of ruby laser, ranging range is 500~2000 kilometers, and error is only
Several meters.Not long ago, the LDM series distance measuring sensor that the research and development centre very still having develops, can be in thousands of meters of measurement ranges
Precision can achieve micron level.Frequently with ruby laser, neodymium glass laser, carbon dioxide laser and arsenic
Light source of the gallium laser as laser range finder.
Further, the light source assembly 1 uses annular light source, and the photomoduel 8 includes camera 81, the camera shooting
The central through hole of annular light source described in first 81 face.
It further, further include ranging mounting base 5, the ranging mounting base 5 is fixed on the rear wall of the fixed plate 3
