Electrical linkage protection system for temperature test box turntable based on multi-information fusion

Abstract

The invention belongs to the technical field of precision instruments and machinery, and specifically relates to an electrical linkage protection system for a temperature test box turntable based on multi-information fusion. The end of a rotating shaft of the temperature test box turntable is provided with a frame lock sensor, a limiting sensor a rotating shaft speed sensor, information collectedby the sensors is processed by a logic control circuit and then transmitted to a computer system, and the collection quantity of each sensor is allocated with a unique binary identification code in the computer system through an I/O board card. Meanwhile, the logic control circuit is further responsible for sending instructions to a sound-light alarm system. The computer system performs differentresponse operations according to different sensor level transformations and the binary identification codes, and drives a follow-up electrical logic control circuit to protect the turntable. The coreof the invention lies in multi-level and multi-aspect protection information collection, fusion and judgment and fast braking responses, and the accuracy and rapidity of the whole protection system can be improved.

Description

technical field [0001] The invention belongs to the technical field of precision instruments and machinery, and in particular relates to an electric linkage protection system for a thermostat turntable based on multi-information fusion. Background technique [0002] The turntable is a high-precision special test equipment, which is mainly used in the fields of inertial device calibration, semi-physical simulation of weapon system, antenna radar control, photoelectric tracking and detection, etc. The thermostat turntable is equipped with a high and low temperature test chamber on the basis of a conventional turntable to provide the high and low temperature environment required for test calibration. On the one hand, the inertial devices and optical instruments to be tested on the turntable are all expensive high-precision instruments and equipment; on the other hand, the temperature control experiment box is large in size and rotates at a specific rate with the turntable, resu...

AI Technical Summary

Problems solved by technology

[0004] To sum up, there are two main problems in the current turntable protection system: one is that the information collected by the sensors is relatively independent, lacking information fusion and logical judgment processing, and it is impossible to eliminate false information; the other is that the load is a large inertia component. Afterwards, it still has a large kinetic energy in the state of free movement, and cannot be braked to stop in a short time.
