Abstract
The utility model discloses a watchtower ranging stagger correcting device, and relates to the watchtower ranging improvement technology. A monitoring camera and lens component (1), a cloud deck (2), a dual-shaft high-accuracy angle sensor (3) and an installation platform (4) form an optical ranging mechanism; the monitoring camera and lens component (1) is installed in a protection cover, and the installation platform (4) is fixedly installed on the top of a forest fireproof watchtower; the dual-shaft high-accuracy angle sensor (3) is arranged on the upper surface of the installation platform (4); a base of the cloud deck (2) is fixed on the upper surface of the installation platform (4); and the monitoring camera and lens component (1) is installed on the upper surface of a rotary body of the cloud deck (2). According to the utility model, the problem that the optical ranging system of the exiting fireproof pre-alarming monitoring system positions the alarm place, the stagger is overlarge, thus the positioning accuracy error is overlarge.
Description
Technical field
This utility model She is Ji the sightseeing tower range finding improves technology.
Background technology
Adopt optical range finding unit to accomplish the location of place of alarm in the fire prevention prewarning monitoring system.The design standards of fire tower all is that pedestal is connected with the body of the tower hinge, and body of the tower can be swung by windage, because the bearing accuracy error that stagger is brought has reached 4000 meters-4300 kilometers.
The utility model content
The utility model provides Yi Zhong sightseeing tower range finding stagger correcting device, and the utility model has solved the location that present fire prevention prewarning monitoring system optical range finding unit accomplishes place of alarm, and stagger is excessive, causes the excessive problem of bearing accuracy error.
For addressing the above problem, the utility model adopts following technical scheme: sightseeing tower range finding stagger correcting device, constitutes optical range finding unit by rig camera and lens assembly 1, The Cloud Terrace 2, twin shaft high-precision angle sensor 3 and mounting platform 4; Rig camera and lens assembly 1 are installed in the protective cover, and mounting platform 4 is fixedly installed in Sen woods fire tower top; Twin shaft high-precision angle sensor 3 is arranged at above the mounting platform 4, and the base of The Cloud Terrace 2 is fixed in above the mounting platform 4, and rig camera and lens assembly 1 are installed in above the rotor of The Cloud Terrace 2.
The utility model provides a cover to solve the device of positioning error technically.
The platform deviation angle that the utility model records with passback through the twin shaft high-precision sensor is used in range finder is calculated and is revised the attitude angle, accomplishes range finding.The utility model can be revised the error that swing causes, the measuring accuracy of Ti Gao sightseeing tower range finding.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model optical ranging schematic diagram.
Symbol description among the figure: rig camera and lens assembly 1, The Cloud Terrace 2, twin shaft high-precision angle sensor 3, mounting platform 4.
Embodiment
With illustrated embodiments the utility model is done detailed explanation below.
， sightseeing tower range finding stagger correcting device as shown in Figure 1 constitutes optical range finding unit by rig camera and lens assembly 1, The Cloud Terrace 2, twin shaft high-precision angle sensor 3 and mounting platform 4; Rig camera and lens assembly 1 are installed in the protective cover, and mounting platform 4 is fixedly installed in Sen woods fire tower top; Twin shaft high-precision angle sensor 3 is arranged at above the mounting platform 4, and the base of The Cloud Terrace 2 is fixed in above the mounting platform 4, and rig camera and lens assembly 1 are installed in above the rotor of The Cloud Terrace 2.
Of Fig. 2, optical ranging schematic diagram: F: optical range finding unit's measuring distance of target point; α: position angle (with the direct north drift angle) obtained by digital The Cloud Terrace; β: the angle of pitch (optical range finding unit's optical axis water and plane included angle); δ: the angle of pitch that the The Cloud Terrace records (angle of optical range finding unit's rotation and optical range finding unit's rotation; P: infield; φ: mounting points geographic coordinate longitude; λ: infield geographic coordinate latitude; Hb: mounting points geographic coordinate elevation; H: setting height(from bottom); T: the optical range finding unit installation place (being installed on pylon or other stilts) that is positioned at the top, infield; TO: optical range finding unit's rotation (perpendicular to surface level); OF: the distance that need record; TF: optical range finding unit's optical axis.L=ctan（δ）（H+h）。Through above measurement parameter, in calculating, revise measuring error.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
