Altazimuth photoelectric theodolite level shaft U-type and T-type structure
but with the expanding field of applications of photoelectric theodolite
the horizontal shaft structure occur great changes. For example
in the marine environment
shipboard conditions
the instrument has a waterproof
corrosion-resistant
easy maintenance and other functions
while carrier-based optoelectronic devices from a single visible television configure the development of integrated infrared system and ranging system as one of the single-station measurement system
due to the spherical structure has sufficient internal space exactly adapted to this need. In this paper
the horizontal axis of a spherical four-way structure. From aspects of the spherical four-way split in the form and shafting design and finite element analysis of the detailed design. A spherical four-way horizontal axis system
diameter 550mm
weight 19kg sphere
in the 40kg load
the maximum deformation of 3.3m
fully meet the requirements. The shaft of the structure of the shaking is less than 2 arc seconds
the vibration test
the re-examination instrument accuracy change is less than 1 arc seconds. Verify that the structure is stable and reliable. 2012 IEEE.

In order to satisfy requirements of real time and parallel control for the space optical remote sensor and implement the high integration of software
a kind of VxWorks-based multitask software architecture was put forward. Firstly
the technological requirements of optical remote sensor were analyzed in detail and functions and performances of the optical remote sensor were fixed. Task that was based on each function of optical remote sensor was compartmentalized. Then
software architecture of optical remote sensor was designed. Finally
experiments were carried out and results verified the accuracy and feasibility of the software architecture. Test results showed that the software architecture satisfied the requirements of real time and parallel control for the space optical remote sensor
its functions and performances met the system design target perfectly
and the software architecture was applicable to the engineering application of space instrument. 2011 IEEE.
