Single Spherical Planetarium Electrical Control System Design

Along with technology development and people are more and more interested in astronomy knowledge,in order to enable the astronomy amateur to be more direct-viewing using planetarium, conveniently to understand the starry sky and the astronomy phenomenon, needs to use optical,mechanical and electronic integration technical change planetarium electrically controlled system, further develops planetarium the function.This article to introduce single-globe planetarium electrically controlled system design as well as to some correlation technology experimental studies.In view of single-globe planetarium characteristic, this article studied has applied PLC and the AC servo electromotor value in the planetarium electrically controlled system, the goal lies in analyzes this design proposal the superiority. In the paper text, in detail introduced the planetarium electrically controlled system composition, the principle as well as the run mode way. Through to the planetarium demand analysis, has derived its electrically controlled system design request, then displays the entire electrically controlled system with the schematic diagram the work process. Have chosen PLC and the drive electromotor model and the specification according to the planetarium technology qualification and the characteristic. According to the planetarium mainframe control demand, has designed the planetarium partial controls flow, and list PLC an input output distribution list. Analyzes regarding this system correspondence question between PLC and the PC machine. Proposed the electrically controlled system design plan, has the practical value.
