Abstract
The utility model provides a semi-automatic sextant. The semi-automatic sextant comprises a rocking handle, a drum wheel and the like and further comprises an intelligent device, wherein the input end of the intelligent device is connected with the rocking handle and the drum wheel; and the output end of the intelligent device is connected with a display device and a communication interface. The sextant can be used for automatically calculating an included angle of a current measured object in real time while the object is manually aimed and measured, and a measurement result is directly displayed through the electronic display screen and can be also transmitted to other electronic equipment, such as a PC (Personal Computer), through the communication interface so as to be provided for other data operations.
Description
Technical field
The utility model relates to a kind of sextant, belongs to the technical field of surveying instrument.
Background technology
Sextant is a kind of optical instrument that is used for measuring the corner dimension that forms between two targets in a distant place and the survey person.Sextant have fixed pan mirror that fan-shaped Wai Xing ﹐ comprises a translucent half reflection of a Xiao Wang Yuan Jing ﹐ namely flexible mirror that links with index of Ping Jing ﹐ be index mirror.The graduated arc of sextant is 1/6 of circumference.The hand-held Liu Fen Yi ﹐ of Shi Yong Shi ﹐ observer rotates index Jing ﹐ makes the measurement thing that occurs simultaneously in the visual field overlap with the measurement thing.Can measure two according to the corner of index mirror and measure the Jia Jiao ﹐ between the thing because therefore its use Qing Bian ﹐, uses more.But because sextant of the prior art in use, all be to check that by the operator scale on the instrument comes reading out data, so automaticity is not high, and the result who reads is not electronic data, can't directly send into computing machine and participate in other related operations.
The utility model content
Technical problem to be solved in the utility model provides a kind of semi-automatic sextant, this sextant can manually taken aim at survey thing target simultaneously, automatically, calculate in real time the current thing target angle of surveying, and by the direct display measurement result of electronic display, this result can also be transferred to other electronic equipments (such as PC) by communication interface, for other data operations.
In order to solve the problems of the technologies described above, a kind of semi-automatic sextant of the utility model, except the parts (comprising rocking handle, drum etc.) that existing sextant has, also comprise a cover intelligent apparatus, the input end of described intelligent apparatus links to each other with described rocking handle, described drum, and output terminal is connected to display device and communication interface.
Above-mentioned semi-automatic sextant, wherein, described intelligent apparatus comprises first signal collecting unit, secondary signal collecting unit, signal processing unit, the input end of described first, second signal gathering unit links to each other with rotating shaft and the described drum of rocking handle respectively, and first, second signal gathering unit output terminal links to each other with the input end of described signal processing unit;
The first signal collecting unit: the angular displacement information to the rocking handle rotating shaft gathers;
The secondary signal collecting unit: the angular displacement information to drum gathers;
Signal processing unit: angular displacement information processed converting corresponding data to, and these data are sent to display device show, be sent to communication interface and carry out data transmission.
Above-mentioned semi-automatic sextant, wherein, described first, second signal gathering unit is rotary encoder.
The beneficial effects of the utility model:
1, owing to be connected to intelligent apparatus on the semi-automatic sextant, by intelligent apparatus the data that show on the sextant are read automatically, avoided the error in operating personnel's operating process, thereby, degree of accuracy and automaticity that the utility model is measured greatly improved; In addition, make the use of sextant convenient; And the utility model is simple in structure.
2, the intelligent apparatus in the utility model comprises first signal collecting unit, secondary signal collecting unit, signal processing unit, gather the angular displacement information of sextant by first, second signal gathering unit, again information is delivered to signal processing unit, the intelligent apparatus of this structure is simple in structure.
3, because described signal processing unit output terminal is connected to communication interface, realized the output of remote signal, used convenient.
4, because first, second signal gathering unit is rotary encoder, can in time safeguard, make things convenient for maintenance of the present utility model, and be convenient for carrying.
