A satellite-oriented electronic control system and method

Abstract

The present invention provides a satellite-oriented electronic control system and method. The payload data transmission subsystem transmits the received second payload data and / or first payload data according to the mode switching instruction and the CCSDS address carried by the payload data through The selected radio frequency band is sent to the ground; the payload data processing subsystem compresses and packs the second payload data and / or the first payload data received from the data bus according to the data processing instructions and the CCSDS protocol, Send the CCSDS data packet containing the second payload data to the data bus, and / or send the CCSDS data packet containing the first payload data to the payload data transmission subsystem; the main control computer generates data processing instructions and mode switching instructions, and passes through the control bus Output data processing instructions and mode switching instructions. By adopting the method and system of the present invention, work efficiency and scalability can be improved.

Description

technical field [0001] The invention relates to the field of aircraft design, in particular to a satellite-oriented electronic control system and method. Background technique [0002] figure 1 It is a structural schematic diagram of the existing satellite-oriented electronic control system. Combine now figure 1 , to describe the existing satellite-oriented electronic control system, as follows: [0003] The existing satellite-oriented electronic control system is installed on the satellite, including: attitude and orbit control subsystem, data storage subsystem, payload subsystem, main control computer, measurement and control communication subsystem, thermal control subsystem, propulsion subsystem 1. Power supply and distribution subsystem and satellite platform bus, each subsystem is connected to the main control computer through the satellite platform bus. [0004] Among them, each subsystem includes a bus remote terminal (RTU) for interacting with the main control co...

Problems solved by technology

[0005] In the existing satellite-oriented electronic control system, due to the bandwidth limitation of the satellite platform bus, only low-speed instructions can be transmitted, and it cannot be used to transmit high-speed payload data or ultra-high-speed payload data. Direct connection mode, to complete high-speed payload data or ultra-high-speed payload data through the main control computer and measurement and control communication subsystem, receive or send in the form of wireless radio frequency, which not only increases the burden on the main control computer, but also reduces the work of the entire system Efficiency; Since the transmission band of the existing measurement and control communication subsystem is certain, when receiving or sending data in the form of radio frequency, only a specific band can be selected, and the scalability is poor
