Abstract

The invention discloses a remote sensing satellite image processing load multi-task main control system, which adopts the "CPU+2FPGA" architecture, wherein the embedded real-time operating system is transplanted to the CPU as the main control management module, which is used to complete the remote sensing satellite image processing load state monitoring and task scheduling, with sufficient flexibility, security and stability; FPGA is used for the integration and distribution of communication information, which can make up for the defects of different CPU interrupt priorities and limited interrupt vector table when facing multiple timing interfaces , while being used for image preprocessing to meet the real-time and low-latency requirements of large data volumes. The system structure design of the invention can not only effectively meet the main control management function, but also meet the high parallel processing requirements of the image and the operation requirements of complex floating-point numbers, and at the same time meet the requirements of system safety, reliability and flexibility.

Description

technical field [0001] The invention belongs to the field of interdisciplinary science and technology combining satellite-borne electronic systems and image processing, and more specifically relates to a remote sensing satellite image processing load multi-task master control system. Background technique [0002] Remote sensing satellite image processing has many load tasks. According to the geometric position relationship among the satellite, the earth and the sun, the deep space area of ​​the earth, the change of seasons and the day and night conditions can be determined quickly to determine the monitoring area to achieve different monitoring purposes; at the same time, the sensor will generate a large amount of image data and Remote sensing information needs to be transmitted to the ground, and satellite image processing loads are required to compress and transmit these data in real time; monitoring tasks require remote sensing satellite image processing load sensors to ma...
