Multifunctional aerial remote sensing triaxial inertially stabilized platform system

Abstract

The invention discloses a multifunctional aerial remote sensing triaxial inertially stabilized platform system, which consists of a main body part and an auxiliary part, wherein the main body part comprises a three-frame system, a driving system, an inertia measurement system, an angular position measurement system and a control system; the auxiliary part comprises a power two-phase knob, a power indicator lamp, a control mode three-phase knob, a control mode indicator, a mechanical locking knob, a manual operation knob, a roll horizontal indicator, a pitch horizontal indicator, a power interface, a point of sales (POS) signal interface, a personal computer (PC) signal interface and four transportation handles. Under the guidance of a POS or the inertia measurement system, the three-frame system tracks a local level and performs real-time compensation and isolation on the angular motion and linear vibration of an airplane to stabilize an optical axis of a camera. The multifunctional aerial remote sensing triaxial inertially stabilized platform system has an automatic working mode, a local leveling working mode, a manual working mode, an electric locking function and a mechanical locking function, can work with the POS or without the POS, and is high in accuracy, flexible in operation and applicable to complicated aerial remote sensing and mapping.

Description

technical field [0001] The invention belongs to the technical field of aerial remote sensing, and relates to a multi-functional aerial remote sensing three-axis inertial stabilization platform system, which can be used for high-precision, large-load aerial remote sensing operations, can meet the multifunctional requirements of aerial remote sensing operations, and is suitable for aviation in complex environments. Remote Sensing and Basic Mapping. Background technique [0002] The high-precision real-time motion imaging in the aerial remote sensing system requires the flight platform to perform ideal motion (uniform linear motion). However, due to the influence of various disturbances, the motion of the flight platform is actually a complex multi-mode high-order random motion, resulting in degradation of imaging quality. . The inertial stabilization platform is responsible for supporting and stabilizing the load, which can effectively isolate the influence of various disturb...

Problems solved by technology

[0004] However, there are many deficiencies in the existing inertial stable platforms, which are generally manifested as systematic deficiencies in volume, load / weight ratio, accuracy, multi-function mode, etc., that is, it is difficult to find a product that integrates the advantages of the above aspects

Due to commercialization and other factors, foreign products with small size and light weight often have low precision and low bearing capacity, while products with high precision often have large volume and weight; in addition, many products lack the actual use requirements of users and the complex flight environment. Due to the consideration of automatic, manual, locking and other operation modes, they are often not available or not available at the same time.
