Description

Manual control method for program uploading

Technical Field

The invention relates to the technical field of meteorological satellites, in particular to a manual program annotation control method.

Background

At present, the FPGA carried in the satellite-borne instrument in the world mainly has two types, namely an antifuse and an SRAM. The former is more widely applied, and is mainly applied to satellite control systems in aspects of attitude and control and the like and satellite-borne electronic products. The SARM type FPGA adopted by the FY4A lightning imager is applied to on-satellite preprocessing of lightning data, and only the lightning data is subjected to on-satellite preprocessing, and the on-satellite preprocessing is mainly used for processing lightning time data, lightning background evaluation value and threshold value data, lightning event partitions, position and intensity data, lightning position verification, landmark observation data and the like. The lightning imager data is divided into 4 paths and processed in 4 FPGA chips respectively, and defined by the subzones of the lightning imager data in each path and the positions of the lightning imager data in a data stream, wherein 6700 defined positions are formed on each chip, and 6700 defined positions are formed on each chip one by one.

The lightning imager respectively adopts a lightning detection mode, a landmark observation mode and a program uploading mode, and each working mode is switched by sending a remote control instruction through a wind cloud four-number ground application system. During the program uploading period, the processing of the lightning detection data or the landmark observation data is stopped by the FPGA chip of the lightning imager, and the program uploading working mode is switched. In the construction of an FY-4A ground application system, high-level maintenance personnel carry out the program annotation control of a lightning imager lightning detection algorithm and the identification of a program annotation result through a task management and control subsystem.

The existing satellite-borne lightning detection algorithm in China is only verified on the ground. After the on-orbit operation, the requirement of long-term satellite-borne lightning detection cannot be met in the face of a complex space environment. The satellite-borne lightning imager cannot autonomously complete the updating of a lightning detection algorithm in an on-orbit running state.

In a specific embodiment of the invention, during the process of program annotation, when the program annotation is stopped in advance, the lightning imager FPGA chip lightning detection algorithm must be reset to the original version; when the program is annotated, if an unplanned event occurs, the FPGA chip is configured to the initial lightning event detection algorithm version.

In order to facilitate understanding of the above-described aspects of the present invention, the above-described aspects of the present invention will be described in detail below.

In a satellite load lightning imager, a lightning event detection algorithm program is written into an FPGA chip data memory which is respectively provided with solidified PROM type and on-orbit modification E PROM type 2 program memories. Before the satellite operates in orbit, a PROM type memory is adopted to write a solidified lightning event detection algorithm 1.0 version program for storage; after the satellite operates in orbit, the E PROM type memory is adopted to store the injected new lightning event detection algorithm 2.0 version program. The lightning event detection algorithm 2.0 version program annotated on the rail only updates the lightning event detection algorithm in the E PROM memory, and the solidified lightning event detection algorithm 1.0 version program is always reserved without updating during emission and is used for resetting and recovering when the annotated new version program fails.

The lightning imager sets a program uploading working mode and respectively sets instructions of 'program uploading start' and 'program uploading end' to switch the working modes. The lightning imager is provided with an FPGA chip to suspend processing lightning detection data and landmark observation data in a program uploading working mode, and only receives and processes the sub-package data of the lightning event detection new algorithm program uploaded on the ground. Setting a program sub-packet data transmission command, and realizing the function of transmitting the new algorithm data packet to the satellite by the ground application system by sending a related command. Setting an FPGA configuration instruction to realize the starting of the new algorithm data packet after the new algorithm data packet is solidified in an FPGA chip; and a version control command is set in the FPGA configuration instruction, so that the system can be recovered to a state during transmission when the upper note part fails.

By setting 4 instructions such as 'program annotating mode starting', 'program annotating mode ending', 'program subpackaging data transmission' and 'FPGA configuration', the starting, data transmission and ending of program annotating and the effective control of the FPGA configuration are realized, and the safe and reliable operation of the lightning imager in the orbit program annotating is ensured.

Due to the fact that space environment and communication link environment in the universe are complex, in the process of program annotating, in order to prevent error data from being written into an FPGA chip caused by single event upset, error codes and the like, a check code of 1 byte is added into every 4 bytes of data in the annotated data, and the check has the function of error detection. The FPGA chip of the lightning imager checks the data after receiving the new algorithm data, checks whether the new algorithm data are correctly written into the E PROM type memory, and returns error telemetering if the new algorithm data are checked to be wrong, and downloads the wrong byte addresses. And the program sub-packet data transmission adopts a sequential sub-packet transmission scheme, the next packet of data is transmitted after the current packet of data is correctly received, solidified and checked, the FPGA chip of the lightning imager starts a new lightning detection algorithm after all the sub-packet data are correctly solidified and the FPGA configuration is carried out through an instruction.

The lightning imager is provided with 4 FPGAs with the same algorithm, the new program of the upper note is stored in the memories of the respective chips, the on-track upper note can be carried out on all 4 FPGAs according to the actual note requirement, the on-track upper note can also be carried out in stages, and any one or more FPGAs can be configured independently.

During the process of upper injection, the lightning imager is placed in a lightning detection state, but does not perform any lightning detection data processing, and the observation task schedule is suspended. And the ground application system controls the lightning imager to stop the processing of the signal in the lightning detection mode and the landmark observation mode. And after receiving the instruction 'program annotation start', the lightning imager terminates the corresponding program, prepares for receiving the annotation program, and feeds back the 'program annotation start execution state' to the satellite platform and downloads the program.

The lightning imager receives 6700 packet data respectively through a remote control instruction and checks check codes, the data are stored in the FPGA chip E PROM type 2 program memories in sequence after correct check, the telemetering parameters of the receiving state of the data packets annotated on the program are returned, and the telemetering signals of abnormal receiving of the data packets annotated on the program are returned if the check is wrong. And after all the subpackage data are uploaded and all the satellite is correctly received, the lightning imager carries out corresponding FPGA program solidification according to the instructions, FPGA configuration is carried out after the solidification is finished, and the configuration result is returned to the ground application system according to the telemetering parameters of the FPGA configuration instruction execution state. And after all the comments are finished, the lightning imager exits the program comment mode and returns to the telemetry parameter of the program comment finish state.

6700 definition areas are arranged on a chip of a load, so that 6700 instructions are needed for injecting a data packet on each definition area; as the frame telemetering return code of the lightning imager 1 needs 8s, and misjudgment caused by abnormal telemetering information due to frame throwing and the like is avoided, the upper note of each packet of data is designed initially, and the instruction interval is 16 s. Only one FPGA needs to be reconfigured, wherein the number of instructions for starting to inject (1), the number of data packets for injecting (6700), the number of data packets for injecting (1), the number of chip data configuration (1), the number of lightning detection (1), the number of matching instructions (2) are needed, and 6706 are calculated. It took about 30h in the case of regular starting. The flow charts of the single chip programs of the FPGA1, the FPGA2, the FPGA3 and the FPGA4 are shown in the figures 2-5.

If all of the 4 chips FPGA1, FPGA2, FPGA3, and FPGA4 are annotated, the required instructions are: the method is characterized in that the method comprises the steps of starting to annotate (1 x 4 pieces), adding an annotating data packet (6700 x 4), finishing adding (1 x 4) + chip data configuration (1 x 4) + a reservation instruction (2 x 3) + lightning detection (1 piece) + a matching instruction 2 pieces =26821 pieces, and the annotating and controlling task consumes about 120h in the whole process. The whole program injection scheme of 4 FPGA chips is shown in FIG. 1:

the FPGA program of the new lightning event detection algorithm is implemented by technical personnel of a satellite load development unit, advanced maintenance personnel of a satellite user, an FY4 ground application system, an FY4 satellite platform and a lightning imager, wherein the satellite load development unit and the advanced maintenance personnel of the satellite user both adopt double posts, and all operations and identification need 2 times of confirmation. And programming the load development unit according to an algorithm provided by a user to generate FPGA configuration data and complete data subpackaging. The program injection scheme is established by a satellite load development unit and high-grade satellite user maintainers together, and the specific implementation is completed by the high-grade satellite user maintainers.
