The Function Design And Reatites Of Data Seconds Auto-Correction Under The Leading States For A Photoelectric Theodolite

With the automation level and the detecting ability of the light and electricalequipment developed higher and higher, the demands on the tracking precision becomesmore and more accurate. A certain kind of the light and electrical theodolite thatmentioned in this thesis, was manufactured by a research center of China in the lastcentury. Since been on active service, it was always fixed on a shooting range ofsomewhere, and for recording the video of them. The ways that this light and electricaltheodolite used to tracking are the video automatic tracking way, the guide tracking wayand the semi-automatic way by jointed arm. Among them, the guide tracking way haslow tracking precision, and the error estimate of this guide tracking way stays still. Thisthesis is aimed at improving the tracking precision of the guide tracking way.This thesis takes use of data secondary revise automatically technology, and do theresearch work from the following two points: hardware and software. On the part ofhardware，we added a monitor and control computer to the light and electric theodolitesystem, which was located in front of the main control computer. By writingcommunication joggle programme, the monitor and control computer can receive theguiding data from command center of outside net, as so as the detecting data fromequipment of inside net. In order to reduce the error estimate of tracking and to improvethe tracking precision, then do the data secondary revise automatically by use of thosedata both received from outside net and inside net. The date that received fromcommand center of outside net was based on the coordinate system of the earth, and thedata that received from detecting equipment of inside net was based on the coordinatesystem of detecting equipment, so that the data revise automatically method can not usethis two kind dates at the same time. Because of that, we researched the transformingmethod between the coordinate system of the earth and of the detecting equipment, itmakes the data revise automatically method possible. On part of software, by analyzingthe function needed to complete, the working environment of the software, data flowdirection, the working mechanism of the software and the inside mechanism of the light and electric theodolite system, this thesis used Visual C++language and TCP/IP netcommunication agreement to write the monitor and control computer’s software. It wasproved that the software written by this thesis can work steady and reliable andaccomplished the purpose at the very beginning of this thesis.The achievement of this thesis replied on our works many times, and they allreceived a good effect. By practicing of the realistic, the achievement of this thesisproved to be work steady and precisely, tracking and capturing aims timely and reliably,the tracing precision got improved greatly and accomplished the purpose at the verybeginning of this thesis.
