Problems solved by technology
[0005] The purpose of the present invention is to solve the problem that the current position limit and speed limit measures of the turntable are not reliable, and once the control system fails, the position limit and speed limit sensors will also fail, and propose a position limit and speed limit protection system based on multi-sensor fusion , its core lies in the multi-angle and multi-level compounding of protection measures to prevent the impact of failure of a single protection measure and improve the reliability of the entire protection system

The present invention belongs to the field of the high-precision servo control, and concretely relates to a rotary table spacing and speed limitation protection system based on fusion of multiple sensors. The objective of the invention is to solve the problems that the rotary table spacing and speed limitation measure is low in reliability and the spacing and speed limitation sensor is failed once a control system is failed. The system comprise a positive first-order spacing sensor, a positive second-order spacing sensor, a spacing driving lever, a positive machinery spacing, a negative machinery spacing, a negative second-order spacing sensor, a negative first-order spacing sensor, a speed measurement sensor, a visual sensor, a rotary table middle-frame visual sign, a rotary table inner frame visual sign and a rotary table outer frame visual sign. The failure risk of a protective system is shared to the protective module of each sensor, and multi-angle monitoring of the corner position and the speed rate of the rotary table is performed through different sensors and different levels so as to ensure that the position speed limitation and the overspeed of the rotary table can be discovered in time.
Description
technical field [0001] The invention belongs to the field of high-precision servo control, and in particular relates to a turntable position limiting and speed limiting protection system based on multi-sensor fusion. Background technique [0002] The present invention relates to a position-limiting and speed-limiting protection system for a turntable, where the turntable mainly refers to precision instruments and equipment used to provide position and speed references for inertial devices, seekers, star sensors, etc., also known as Test equipment for inertial devices, not similar equipment that can achieve rotation in the field of industrial equipment. The reason why the turntable limit and speed limit protection system is specially proposed is that the objects to be tested using the turntable such as inertial devices, seekers, and star sensors are very expensive, and the general price ranges from tens of thousands to millions, so the limit of the turntable In fact, the pos...
