The invention discloses a manual control method for program injection. The method includes programming the algorithm, generating FPGA configuration data, and subcontracting the data; receiving and parsing the command from the satellite and forwarding it to the lightning imager; returning the verification and curing telemetry Parameters to the data acquisition and measurement and control system of the FY4 ground application system; after judging that all the subcontracted data are transmitted correctly, send FPGA configuration commands and remote control commands to control the on-board FPGA chip for configuration; the results of the program are written by the satellite payload development unit and senior maintenance personnel of satellite users End betting after mutual confirmation. Through the construction of the ground system, it has the ability to control by means of ground intervention; in order to ensure that during the satellite’s in-orbit operation, the program can be completed without affecting the operation of other payloads, and the load requirements, the amount of program injection data, Overall planning of ground application system resources, etc., design of full-process solutions, ordering strategies, and on-board execution plans.
Description
technical field [0001] The invention relates to the technical field of meteorological satellites, in particular to a manual control method for program injection. Background technique [0002] At present, there are two types of FPGAs carried in spaceborne instruments in the world: antifuse and SRAM. Among them, the former is more widely used, mainly used in satellite control systems such as attitude and control, and satellite-borne electronic products. The SARM-type FPGA used in the FY4A lightning imager is used to preprocess lightning data on the star, and only for lightning data on-board preprocessing, which is mainly used to process lightning time data, lightning background evaluation value and threshold data, lightning event partition, Location and intensity data, lightning location verification, landmark observation data, and more. The data of the lightning imager is divided into 4 channels and processed in 4 FPGA chips respectively. It is defined by its sub-area in ea...
