Problems solved by technology
However, in the above scheme, the signal transmission between the three-level computers is controlled through wired connections, and the scale of this super-large telescope is huge, and it is completely dependent on wired connections and wired control, which will cause great difficulties and problems in use. Observation practice has proved that it is very necessary to realize remote control on such a large astronomical telescope
At the same time, as the number of factors to be controlled increases geometrically, the above-mentioned three-level computer control can no longer improve the control accuracy, and this control mode can no longer become the basis for a new round of technological progress.

The present invention relates to an electric control system for astronomic telescope active optic active support. Its main control computer is respectively connected with several slave computers; every slave computer is respectively connected with several intelligent controllers; every intelligent controller also is repectively connected with several sleeve force actuators. It is characterized by that the higher level of said main control computer is equipped with a total control computer, said total control computer is connected with main control computer to implement four-order control, at the same time the total control computer, main control computer and every slave computer have communication interface respectively, and every intelligent controller is equipped with an independent embedded CPU main board with communication interface. On the total computer, main control computer, slave computer and intelligent controller also optical-fibre communication modules are set at the same time so as to form optical-fibre communication interface board. So that it can utilize optical-fibre communication to implement remote high-speed monitoring and control.
Description
technical field [0001] The invention relates to a control device for an astronomical telescope, in particular to an electronic control system for the active optical active support of the astronomical telescope. Background technique [0002] Active optical telescope is a new technology of modern astronomical observation. The emergence of this technology is to solve the technical difficulties of building a large-scale astronomical telescope with a large aperture, and a large-scale astronomical telescope is formed by splicing multiple sub-mirrors; each sub-mirror in the splicing structure moves simultaneously under the control of the control system to form the entire mirror surface The deformation meets the needs of astronomical observation, which constitutes an active optical astronomical telescope. The technical difficulty of this large-scale active optical astronomical telescope with splicing structure lies in the control system: it needs to meet the technical requirements ...
