(4) the sample states information of the piece 5 preservation instruments of SD card, sample states is used for the state of each sampling period institute's corresponding data of record, accounts for 1 byte, and 0xff represents not yet to begin; 0x00 represents to begin but not normal termination on time; 0x01 represent not begin on time or in have no progeny and restart and not normal termination; 0x02 represents to begin normal termination on time; 0x03 represent not begin on time or in have no progeny and restart but normal termination, each sample states repeats five times, remainder keeps in the 500 byte continuous arrangements before this piece, this piece;
(5) from the 6th BOB(beginning of block) store sample information of SD card, the corresponding one group of sample information of the data that each second samples, different according to sampling rate, every group of size multiply by 64 bytes for sampling rate, and the data total length is according to different variation of sampling time.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
Storage when 1, having realized the configuration information of instrument and Information Monitoring;
2, increased the CRC check code of data;
3, in order to ensure the reliability of the data, increased data backup;
4, designed special-purpose data memory format.
Four, embodiment:
The present invention is described in detail below in conjunction with embodiment.
The concrete steps that the present invention adopts are: (1) manages by data block the SD card, and each piece accounts for 512 bytes;
(2) configuration information be kept at the SD card piece 0 to piece 3,4 parts of coexistence storages are in order to still can correctly read configuration information when bad piece occurs;
(3) piece 4 of SD card has been preserved the temporal information that instrument begins to start sampling, and this numerical value is 32 integers, and this numerical value is repeated to preserve 128 times piece 4 is interior altogether, increases reliability;
(4) piece 5 of SD card has been preserved the sample states information of instrument.Sample states is used for the state of each sampling period institute's corresponding data of record, accounts for 1 byte.0xff represents not yet to begin; 0x00 represents to begin but not normal termination on time; 0x01 represent not begin on time or in have no progeny and restart and not normal termination; 0x02 represents to begin normal termination on time; 0x03 represent not begin on time or in have no progeny and restart but normal termination.Each sample states repeats five times, and remainder keeps in the 500 byte continuous arrangements before this piece, this piece.
(5) from the 6th BOB(beginning of block) store sample information of SD card.The corresponding one group of sample information of the data that each second samples.Different according to sampling rate, every group of size multiply by 64 bytes for sampling rate.The data total length is according to different variation of sampling time.
This is mining, and the node type seismograph adopts the SD card to carry out the storage of Large Volume Data.In order to ensure the safety of data, the SD card adopts RAW pattern storage data, does not namely set up file system on the SD card, just the SD card is read and write as a continuous storer, can realize so the rapidly, continuously storage of data.The seismographic data of mining node type comprise the configuration information of instrument and actual sample information two parts, and we are divided into configuration information with the data in the SD card and sample information two parts are stored for this reason.We manage by data block the SD card, and each piece accounts for 512 bytes.
When being sampling parameter, the instrument work of the instrument that arranges, configuration information samples according to these settings.Every group of configuration information is 512 bytes, and concrete form is as shown in table 1.
