Study On Integrated Application Of Rangefinder And Electronic Theodolite And Key Technologies

This paper describes the technology involved the whole process of integration realization between the new type of narrow pulse laser range finder and electronic theodolite. It includes the integral design of the electronic theodolite, which adopt a single code word absolute coding techniques achieving level2"side Angle precision, and its prototype debugging, trial, etc; It also includes pulse laser ranging technology, which adopts a narrow pulse laser emission and time to digital converter to realize high-precision time interval measurement.At first, this paper depicts the overall engineering project products technical indicators, and then to realize the index requirements and solutions products industrialized production process problems as the principle in all design. Then, in terms of electronic theodolite related technology research, introduces the electronic theodolite core structure parts, high precision of shafting design, the design of the single code word absolute code disc and using linear CCD subdivision technology for implementing image acquisition, decoding coded disc electronic theodolite Angle measurement capacitor compensator design, electronic theodolite liquid mass engineering detailed technical analysis, and is suitable for the production of liquid crystal display (LCD) module of electronic theodolite/operation panel design, electronic theodolite other application of techniques such as functional design; Then, it introduces the design of a new type laser rangefinder, which is small and portable and can be integrated in electronic theodolite. It describes mainly the range finder and the principle of integration of electronic theodolite and light machine system integration mechanism to design. What is more important is to discuss the implementation of the contact ratio relations, assembly debugging of the three axis (laser axis, telescopic aiming optical axis and rotation axis),which is applicable to engineering production, and as well as the function of the software design for the use of measure engineering after the electronic theodolite and rangefinder integration; At last, the omni-directional professional detection is carried on for the whole design system prototype technology index.Finally, the result that related technical design can realize the expected indicators of project generally is carried out.
