Description
Technical field
What the present invention relates to is a kind of FLASH data programming method that intelligent substation protection supervisory equipment adds verification; what be specifically related to is a kind of based on TCP(Transmission Control Protocol; transmission control protocol) the FLASH data programming method that can verify under mode, belong to power system automatic field.
Background technology
Intelligent substation and intelligent assembly intelligent substation are combined by advanced, reliable, energy-saving and environmental protection, integrated equipment; with high-speed network communication platform for Information Transmission System; automatically complete the basic functions such as information acquisition, measurement, control, protection, metering and monitoring, and the transformer station of the senior application functions such as electrical network control automatically in real time, Intelligent adjustment, on-line analysis decision-making, collaborative interaction can be supported as required.And intelligent substation protection supervisory equipment uses high-performance embedded multi-core CPU to become mainstream configuration, general operation LINUX operating system, in order to the needs of satisfied replacing program, needs to carry out programming to device FLASH.
But the time that the burning of FLASH itself needs at present adds one times, the BMC of main flow adopts the microprocessor of ARM9 kernel mostly now simultaneously, mostly adopt in the process of debug and download bootloader to SPI FLASH by JTAG, first this mode will be written to bootloader in SDRAM by JTAG, then in SDRAM, bootloader is started, then firmware is downloaded by the tftp instrument of bootloader, and then in write SPI FLASH, first the time that this mode needs is long, besides for some ARM chip, also needing to send out some configuration script orders by JTAG could download in sdram bootloader, development difficulty is strengthened, and easily producing protection supervisory equipment FLASH data programming error code problem, writing speed is slow, improper for mass-production stage.
Summary of the invention
For the deficiency that prior art exists; the object of the invention is to provide a kind of FLASH data programming method based on verifying under TCP mode; the quick programming of low-voltage variation measure and control device implementation data to operation LINUX operating system can be completed and checking data; solve protection supervisory equipment FLASH data programming error code problem, the data programming made is reliable.
To achieve these goals, the present invention realizes by the following technical solutions:
Based on the FLASH data programming method that can verify under TCP mode, comprise the following steps:
(1) be connected with target FLASH module creation;
(2) import file calculation document size and CRC check code, then download;
(3) whether judgement and target FLASH module connect successful; If success, enters step (4); If unsuccessful, then return error code, close and connect;
(4) to target FLASH module transfer data, then judge whether transmission data terminate, resolution data after transmission ED also calculates CRC check;
(5) CRC check compares with CRC when importing file, judges whether data check passes through; If pass through, then to FLASH writing in files, write FLASH by CRC check by data; Otherwise return error code, close and connect;
(6) read the FLASH data of write and recalculate CRC check, again comparing with CRC when importing file, again judge whether data check passes through, guaranteeing that whether the data write are correct;
If pass through, then return correct code, close and connect;
If do not pass through, then return error code, close and connect.
The beneficial effect that the present invention has compared with other FLASH programming methods is:
The present invention is by being connected with protection supervisory equipment and FLASH module; will programming data packing and calculation check; data are imported into protection supervisory equipment internal memory, finally data and inspection write FLASH, and will the data reading of FLASH be write and calculation check; the no write de-lay of complete twin installation data solves protection supervisory equipment FLASH data programming error code problem; the data programming made is reliable, and it has and can verify, and speed is fast; reliably, the advantage such as accurate.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is process flow diagram of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
The present invention forms software flow to realize the quick programming of FLASH data that intelligent substation protection supervisory equipment adds verification; it is the FLASH data programming method based on verifying under TCP mode; complete the quick programming of low-voltage variation measure and control device implementation data to operation LINUX operating system and checking data, the overall step of the method is as follows:
(1) be connected with target FLASH module creation;
(2) import file and calculate CRC check code;
(3) file subpackage is sent in object module;
(4) by Data Analysis and calculate CRC check with import file time CRC compare;
(5) the data write FLASH passed through will be verified;
(6) will write FLASH data reading and recalculate CRC check guarantee write data correct.
See Fig. 1, the present embodiment is better elaboration implementation result of the present invention, should be as follows based on the detailed concrete steps of the FLASH data programming method that can verify under TCP mode:
(1) incipient stage, be connected with target FLASH module creation;
(2) import file calculation document size and CRC check code, then download;
(3) whether judgement and target FLASH module connect successful; If success, enters step (4); If unsuccessful, then return error code, close and connect;
(4) to target FLASH module transfer data, then judge whether transmission data terminate, resolution data after transmission ED also calculates CRC check;
(5) CRC check compares with CRC when importing file, judges whether data check passes through; If pass through, then to FLASH writing in files, write FLASH by CRC check by data; Otherwise return error code, close and connect;
(6) read the FLASH data of write and recalculate CRC check, again comparing with CRC when importing file, again judge whether data check passes through, guaranteeing that whether the data write are correct;
If pass through, then return correct code, close and connect;
If do not pass through, then return error code, close and connect.
By above-described embodiment, the present embodiment can complete running the quick programming of low-voltage variation measure and control device implementation data of LINUX operating system and checking data, and solve protection supervisory equipment FLASH data programming error code problem, the data programming made is reliable.
Based on above-mentioned; the present invention by being connected with protection supervisory equipment and FLASH module, will programming data packing and calculation check, data are imported into protection supervisory equipment internal memory; finally data and inspection write FLASH; and will the data reading of FLASH be write and calculation check, the no write de-lay of complete twin installation data solves protection supervisory equipment FLASH data programming error code problem, and the data programming made is reliable; it has and can verify; speed is fast, reliably, and the advantage such as accurate.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
