Abstract

With the wide application of computer technology and the rapid development of modern communication technology and the Internet / Intranet, the Internet has become a wide coverage and is extremely convenient data transmission channel, researchers and corporate staff via the Internet at any time, any place automation equipment for remote real-time control and access to information needed, and through the video to see live real-time scenario. In this thesis, the remote control device for science telescope. The development of astronomical observations in China is relatively backward position, due to the limitations of the observing conditions, can not be large-scale popularization of astronomical observations in the eyes of many people still out of reach. By remote control, video transmission through the terminal, so that more people can understand astronomy, opened up a new type of astronomical research and education mode into the astronomical observations in the field of popular science. Telescope remote control system consists of three parts: the telescope electronic control systems, remote control systems, video image transmission system. The electronic control system of the telescope by the motor, encoder, electronic control box, interface card, computer, drivers, etc.. Electric control box can be controlled independently telescope, the completion of the the basic telescope electrically controlled operation, receiving an operation signal of the hand control box, controls the motor according to a variety of speed and direction of movement, and the position of the telescope from a code wheel mounted on shafting, automatic handle limit and protection, sent to a computer telescope the current position, the receiving computer control signal, automatic shutdown and power-down memory telescope state. Connected to a computer, and have the sidereal time is displayed in real time, automatically find the stars guide star tracking correction can be linked with electronic star map complex functions of the telescope greatly improve operability. Can be calculated by the computer in time to a given the current position of the celestial equator device, hour angle and declination on the the besylate device, the height and orientation. Position feedback means in a position of the spindle or drive chain add the computer according to the difference between the current position and the current position of the telescope of the celestial bodies, can determine the direction and speed of movement of the telescope, the driving movement of the telescope to the location of celestial bodies, which is automatically find star. For the movement of the Earth's rotation, computer-controlled stepper motor coordinates ongoing correction. Through the establishment of the C / S server, computer remote control, remote video signal transmission installation of network cameras. This paper presents the control system, which combines site acquisition and control technology and top network communications management technology, making high-speed LAN at any time can control objects in real-time control operations, and technically can be extended to wide-area Internet online, making a control object can be easily carried out in the worldwide process control operation. This paper first introduces the current situation of remote control technology in modern society, the progress of the telescope at home and abroad in the field of remote control, while the prospect of popular science telescope remote control. Second, from the perspective of system integration, the overall architecture astronomical telescope remote control, and the fundamental role of the various parts of the sub-unit focuses on the electronic control system, including the basic principles of the stepper motor system, step-by-step how to control AT89C51 microcontroller into the operation of the motor and the impact of the Earth's rotation designed servo system. Third describes the network technology used by the remote control, such as socket technology, as well as how to realize the transmission of the video signal. Finally, the instance of the system in actual operation and a brief description. The same time, the paper summarizes the system architecture, and industrial prospects do.
