Abstract

The invention discloses a telescope rack control system. The signal input end of a motion controller is connected with an azimuth axis encoder and a pitch axis encoder, the signal output end of the motion controller is connected with an azimuth axis actuator and a pitch axis actuator in a controlled mode, and the azimuth axis actuator and the pitch axis actuator are connected with an azimuth axis torque motor and a pitch axis torque motor in a control mode respectively; a single chip microcomputer control system comprises a single chip microcomputer, the signal input end of the single chip microcomputer is connected with a pitch axis speed measuring motor, an azimuth axis speed measuring motor, a pitch axis limit switch, an azimuth axis limit switch and a position sensor, the signal output end of the single chip microcomputer is connected with an azimuth axis actuator power source, a pitch axis actuator power source, an azimuth axis power-off brake, a pitch axis power-off brake and a stepping motor actuator, and the stepping motor actuator is connected with a stepping motor; a computer is connected with the motion controller and the single chip microcomputer in a controlled mode. It can be effectively prevented that an azimuth axis and a pitch axis exceed a motion range to cause faults, and safe operation of a telescope is ensured.

Description

technical field [0001] The invention relates to the fields of control and electronics, in particular to a telescope frame control system. Background technique [0002] It is difficult for existing telescope systems to quickly track random moving targets, and a telescope system with faster speed, higher acceleration, and higher precision is required, and at the same time, it has perfect protection measures and a high degree of automation. Contents of the invention [0003] The invention provides a telescope frame control system, which solves the requirements for the speed, acceleration and precision of the telescope system. At the same time, multiple protections are designed to prevent system failure, and functions such as closed-loop focusing are designed. Specifically, it has the following functions: azimuth axis servo Control, pitch axis servo control, limit protection, stall protection, closed-loop focus control, etc. [0004] The technical scheme adopted in the presen...
