Satellite-borne measurement and control data transmission all-in-one machine FPGA program on-orbit reconstruction system and method

Abstract

The invention provides a satellite-borne measurement and control data transmission all-in-one machine FPGA program on-orbit reconstruction system which is characterized in that after a processor ARM chip receives a forming reconstruction instruction sent by a satellite service computer, chip selection signal connection between an FPGA and two SPI flash chips is cut off through a control bus buffer gate, meanwhile, the processor ARM chip reads uploading data from the FPGA through a serial port, and the uploading data is sent to the SPI flash chips; using an SPI (Serial Peripheral Interface) bus to realize program writing of an upper injection memory; the SPI memory is used for storing program codes required by operation of the FPGA chip; and the bus buffer gate is used for controlling the FCSB of the FPGA chip selection pin and the chip selection pins of the two SPI memories to be enabled and conducted. According to the satellite-borne measurement and control data transmission all-in-one machine system, a bus buffer gate is additionally arranged on a circuit, and an FPGA code storage SPI chip is additionally arranged, so that a program on-orbit upgrading function can be realized; a special refreshing chip or control chip is not required to be loaded by a complex FPGA, the required extra power consumption is very low, the cost is very low, and the method is suitable for the field of commercial spaceflight.

Description

technical field [0001] The invention belongs to the technical field of FPGA program reconstruction, in particular to an on-orbit reconstruction system and method of an FPGA program of an on-board measurement, control and digital transmission integrated machine. Background technique [0002] At present, most satellite measurement and control, data processing unit of digital flyer, etc. use the flexible architecture of FPGA+ARM. [0003] The measurement and control digital transmission integrated machine and the ground measurement and control digital transmission station jointly establish a satellite-to-ground link to complete the satellite-to-ground remote control / telemetry and ground data transmission tasks. The main functions of the measurement and control digital transmission integrated machine are as follows: [0004] 1) Remote control: satellite-to-ground remote control data reception. Receive the X-band uplink spread spectrum remote control signal sent by the ground m...
