Label point data packet (band markers) 201 is split as one or more label points, this process is to split data 211.It is every after fractionation
One label point is the amount of a detection, such as can be a temperature value or a pressure value.Processor 121 is every after splitting
One label point adds the markers in above controller 111.Processor 121 judges that above-mentioned label point is analog quantity label point or opens
Label point is measured in pass, this process is that analog quantity judges 212.Processor 121 to analog quantity label point and switching value label point respectively into
The compression of the row first order.121 pairs of the processor analog quantity label points and switching value label point by first order compression carry out respectively
Second level compression.Processor 121 stores the analog quantity label point and switching value label point compressed by the second level.Of the invention
In some embodiments, the analog quantity label point compressed by the second level and switching value label point are formed data block by processor 121
It is put into internal storage data block 123b, and stores onto hard disk 126.
In one example, by the historical data software in host computer by compressed analog quantity label point and switching value mark
The value of label point forms data block, and stores to hard disc of computer.Other programs can retrieve the history in the historical data software
Data.
In one embodiment of this invention, the processor 121 of above-mentioned historical data compression set 100 is in above-mentioned label point
Analog quantity label point and after switching value label point carries out first order compression respectively, by through overcompression analog quantity label point and
Switching value label point is sent into data queue, and above-mentioned second level compression is waited for.The data queue for example can be positioned at Fig. 3
Two buffer areas in memory RAM123, buffer area can play the role of buffered data, processor avoided to have little time to handle.
In another embodiment of the invention, the processor 121 of above-mentioned historical data compression set 100 is to above-mentioned label point
In analog quantity label point and switching value label point carry out first order compression respectively after, by the analog quantity label point through overcompression
It is sent into same data queue 123a with switching value label point, waits for above-mentioned second level compression, as shown in Figure 4.
In one example, data queue 123a is located in the buffer area in the memory RAM123 in host computer 120,
The length of the buffer area can be with predefined, to store enough 10 seconds or all record values of longer time.Compressed simulation
The record value of amount label point and switching value label point is stored using queue mode in chronological order.
In one embodiment of this invention, above-mentioned historical data compression set 100 to above-mentioned analog quantity label point first
Grade compression is different from the method that the second level is compressed.It can be improved compression ratio using different compression methods.Preferably, with reference to Fig. 4
Shown, processor 121 compresses 213 to the first order boil down to analog quantity distance of swimming of above-mentioned analog quantity label point, to above-mentioned analog quantity
The second level boil down to analog quantity slope compression 215.Processor 121 can also be frequency pressure to the second level compression of the analog quantity
Contracting (not shown).Wherein, to the distance of swimming boil down to lossless compression of analog quantity label point, the error of compression can be with predefined, should
Error minimum can be 0, usually the 0.1%~1% of range, and the time cycle compressed equally can be with predefined.To mould
When analog quantity label point carries out slope compression and is put into internal storage data block 123b, guarantee that time precision is 50 milliseconds.
In one embodiment of this invention, above-mentioned historical data compression set 100 to above-mentioned switching value label point first
Grade compression is different from the compression ratio that the second level is compressed.In some embodiments of the invention, refering to what is shown in Fig. 4, processor 121 is right
The first order boil down to switching value displacement compression 214 of above-mentioned switching value label point, opens the second level boil down to of above-mentioned switching value
Quantitative change position compression 216 is closed, the compression ratio for conjugating compression twice is different.It can be improved whole compression using different compression ratios
Rate.The compression type of the first order and second level compression to switch label point is usually the compression of time dimension.Switch amount mark
When label point carries out displacement compression and is put into internal storage data block 123b, guarantee that time precision is 1 millisecond.
In one example, above-mentioned historical data compression set 100 to the compression of the first order of above-mentioned switching value label point with
The mode of second level compression includes the label point for merging the value of switching value and not changing.In above-mentioned historical data compression set 100
When switch amount label point carries out first order compression, the value of the switching value changed is only recorded, and merge time identical switch
The value of amount.If the value of switching value does not change, one record value of generation in longest 1-5 minutes.Similarly, in above-mentioned history number
When carrying out second level compression according to 100 switch amount label point of compression set, when only recording the value of the switching value changed, and merging
Between identical switching value value.If the value of switching value does not change, the value of the switching value of front is recorded.In the value of switching value
In the case where remaining unchanged for a long period of time, the value of one switching value of every 1 hour or so record.Only the switching value of variation is saved, it can be with
Under the premise of guaranteeing that all switching value changing values are recorded, the memory headroom of its occupancy is saved, and improves the place of processor
Manage efficiency.By carrying out specially treated to unconverted switching value for a long time, compression ratio can be further improved.
In one embodiment of this invention, the processor 121 of above-mentioned historical data compression set 100 is additionally configured in detection
State the mutation of analog quantity label point, and uncompressed and directly record mutation value.It is carried out by the mutation to analog quantity label point
Specially treated, it is ensured that all compression results are in the error range of predefined.
Another aspect of the present invention proposes a kind of historical data compression method.This method helps efficiently and reliably to realize
Acquisition, compression and the storage in later period of data, improve time precision and data compression rate, solve the problems, such as loss of data.
The historical data compression method flow chart of one embodiment of the invention is as shown in Figure 5.Below with reference to Fig. 5 to historical data
Compression method is illustrated.
Step 302, markers is added to the label point data packet of process variable.
Step 304, the label point data packet of process variable is split as one or more label points, and added for each label point
Add the markers.
Step 306, in the label point analog quantity label point and switching value label point carry out first order compression respectively.
Step 308, second level pressure is carried out respectively to the analog quantity label point and switching value label point compressed by the first order
Contracting.
