The level state of flat data is exactly low level；If the value of the corresponding Wave data of any one group of level data is in two adjacent thresholds
In the range of level, then the level state that this group of level data is arranged is in intermediate level, such as Fig. 8 according to sampled point 250-
The level state for the level data that Wave data between 300 is formed is exactly high level.
Step S300 pre-processes each group of level data according to preset data compression rule, obtains compression number

Such as Fig. 8, for the one group of level data formed according to the Wave data between sampled point 100-250, Ke Yiyong
32 binary arrays are indicated.Setting binary array is made of " 29 3 high+low ", with the first of high 3 compositions
Being worth (such as 0b000 or [000], " 0b " are binary meanings) indicates low level, the second value (such as 0b101) constituted with high 3
Intermediate level is constituted, the third value (such as 0b011) constituted with high 3 indicates high level.It is possible to set 0b000,
100 } level data that the Wave data in Fig. 8 between sampled point 0-100 is formed is indicated, wherein 0b000 indicates this group of level number
According to being low level, 100 indicate that the level width of this group of level data is 100 data points；Can with set 0b011,
150 } level data that the Wave data in Fig. 8 between sampled point 100-150 is formed is indicated, wherein 0b011 indicates this group of level
Data are high level, and 150 indicate that the level width of this group of level data is 150 data points；Can with set 0b101,
50 } level data that the Wave data in Fig. 8 between sampled point 250-300 is formed is indicated, wherein 0b101 indicates this group of level number
According to being intermediate level, 50 indicate that the level width of this group of level data is 50 data points；Other groups of level data can be with
It is indicated, is not discussed here using similar aggregate form.
Then, binary array is can be obtained into the binary system that the corresponding set of every group of level data is converted to 32.This
In to be illustrated for set { 0b011,150 }, 150 corresponding binary systems are 0b1,001 0110, gather together enough low 29 0b0
0000 0,000 0,000 0,000 0,000 1,001 0110, being combined with high 3 0b011 can be obtained binary array
0b0110 0,000 0,000 0,000 0,000 0,000 1,001 0110, " 0b " here are binary meanings.In order to save number
According to memory space, which can be converted, obtain the compressed data of Hexadecimal form, i.e.,
0x60000096, " 0x " here are the hexadecimal meanings.It is possible to conveniently obtain according to set { 0b000,100 },
The compressed data that { 0b101,50 }, { 0b000,150 } are respectively obtained is 0x00000064,0xA0000032,0x00000096.
It should be noted that other level states can also be set as desired, time low electricity such as is indicated with 0b001
It puts down, time high level is indicated with 0b010, is indicated to maintain level with 0b100, indicate reserved expansion level with 0b110,0b111, so
Enough numerical value can be reserved to meet the extending space of level state.

Step S410, obtain high M in the corresponding binary array of compressed data with it is N low, according to N M high, low
Level state, the level width of compressed data are determined respectively.
For example, binary array is 0b0,110 0,000 0,000 0,000 0000 for compressed data 0x60000096
0000 1001 0110.In decoding process, high 3 for extracting the binary array according to MIL-STD-1553B agreement are
0b011 thereby determines that the level state of the compressed data is high level；Low 29 for extracting the binary array are 0b0 0000
0000 0,000 0,000 0,000 1,001 0110, thereby determine that the level width of the compressed data is 150 data points.
Step S420 forms decoding data using the level state and level width of compressed data.
For example, level state is high level for compressed data 0x60000096, level width is 150 data points,
Decoding data is so formed after decoder in the compressed data.It should be noted that being formed by decoding data and being mainly
Signal transmits the data content of corresponding agreement, and followed by additional information is (such as frame number, frame initial time, a frame data content
Starting and ending position etc.).Such as: signal is IIC data transfer signal, then corresponding threshold level is set, according to this technology
Plan content compresses the Wave data that acquisition is formed to obtain compressed data, and compressed data is assisted by decoder completion according to IIC
