Telescope control system and method

Abstract

The invention discloses a telescope control system and method. The system comprises a short-range control terminal and a remote controlled terminal. An Ethercat master station is arranged in the short-range control terminal, and an Ethercat slave station is arranged in the remote controlled terminal. The Ethercat master station is used to send a telescope control command to the Ethercat slave station. The Ethercat slave station is used to receive the telescope control command, so that a motor used for adjusting the pose of the telescope in the remote controlled terminal carries out the telescope control command. According to the telescope control system provided by the invention, the Ethercat master station is arranged in the short-range control terminal, and the Ethercat slave station isarranged in the remote controlled terminal; the telescope control instruction is transmitted by the Ethercat system; and compared with the method of using serial port communication in the prior art, the system has farther control distance, and the Ethercat system has the advantages of simple wiring, high system reliability and better real-time performance.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a telescope control system and method. Background technique [0002] The large-aperture photoelectric telescope is a long-distance comprehensive observation system integrating optics, mechanics, and electronics. It is an important observation equipment used to observe space targets and explore the mysteries of the universe. It has a history of hundreds of years of development. With the increasing demand for observation of astronomical targets, large aperture telescopes emerged as the times require. Typical large-aperture telescopes include 8.2-meter-caliber VLT, 10-meter-caliber Keck, 10.4-meter-caliber GTC, and China’s LAMOST; ultra-large-caliber telescopes, such as the 22-meter-caliber GMT and 30-meter-caliber TMT etc. China is also planning to build a super-large-aperture telescope of the order of 30 meters. These telescopes use leading high-tech technologies such ...

Problems solved by technology

Although the serial communication method, the theoretical communication length can reach more than 100 meters, but as the communication distance increases, the bit error rate of communication also increases.

[0004] Therefore, the serial port communication method cannot meet the data control requirements at a longer distance, and the serial port communication method will greatly increase the number of wiring in the system and reduce the reliability of the system
