The Method of Building the Digital Model of the Photoelectric Theodolite and Its Application

The design and detect process of photoelectric theodolite are analyzed,and the insufficiencies of the process are pointed out at first.Based on this,a method is found out by which the whole theodolite system is divided into the associated disciplines models,several modeling software's functions are analyzed,and a final integration digital model from these concurrent tasks is completed in the virtual simulation environment.The development process is guided and the performance index of the theodolite is evaluated by analyzing the digital model.Then the development environment and the concrete method of modeling and simulation of the photoelectric theodolite are preliminarily explained.The method makes performance evaluation,simulation of the process of the theodolite in advance in the design process come true and also realizes the detection of various error index based on the error simulation.The new method will also improve the system performance.
