Photoelectric stable platform

Abstract

The invention relates to a photoelectric stable platform, which has a vibration-isolating inner ring and a plurality of frames. The photoelectric stable platform comprises an outer ring frame, an inner ring frame and an even number of vibration isolators of the same specifications, wherein various sensors are placed on the inner ring frame; and the vibration isolators are symmetrically installed relative to the centre of mass of the integration of the inner ring frame in which the various sensors which are installed. The invention has the advantages that: an isolation effect of the photoelectric stable platform on external interference is good; imaging quality and stabilization precision are high; the photoelectric stable platform is small in size, light in weight, large in bearing capacity, and convenient for assembly and disassembly; the weight of the platform can be reduced effectively; the assembly of the photoelectric stable platform can be adjusted quickly and conveniently according to requirements; and the photoelectric stable platform is characterized by simple structure, wide application range and the like.

Description

technical field [0001] The invention relates to a photoelectric stabilization platform, which is a multi-frame photoelectric stabilization platform with inner ring vibration isolation, in particular to a photoelectric stabilization platform used under vibration and impact conditions, and belongs to the technical field of photoelectric stabilization and balance in aircraft and aviation technology. Background technique [0002] Payloads such as photoelectric sensors need to be stabilized with high precision during work so that they can track or lock high-speed moving targets. Under external vibration and shock conditions, it is difficult to achieve high-precision stability by relying solely on the servo system of the photoelectric stabilization platform. Generally, passive vibration isolation measures are required to ensure the stability accuracy and imaging quality of the photoelectric stabilization platform. At present, under the existing technical conditions, the vibration ...

AI Technical Summary

Problems solved by technology

This vibration isolation method is not only large in size and heavy in weight, but more importantly, its use effect is greatly affected by external disturbances such as vibration, impact and aerodynamics of the carrier.

Under traditional technical conditions, the inner and outer ring frames of the multi-frame stable platform are fixedly connected by screws and other connectors. Interference can still be transmitted to the inner ring sensor system through the inner ring frame, thus affecting the imaging quality and tracking accuracy. More importantly, the inner ring platform where the photoelectric sensor is installed cannot be easily disassembled, so it is very inconvenient to install and debug the photoelectric sensor

At the same time, due to the limitation of suitability, the weight of the stabilized platform and payload should be as light as possible. Usually, the stabilized platform of the ring frame type is heavy in weight, large in size and not compact in structure.
