Alternatively, before data collecting module collected detection data, data file is first set up, and the data set up are literary
The size of part then need by data acquisition module according to detection time, frequency acquisition and detect data length determines, wherein, examine
Survey data length can with but be not limited to 16bits, 64bits and 128bits etc..
It is determined that after the size for the data file set up, setting up the data corresponding with the size of above-mentioned data file
File.For example, detection time is 5 days, and frequency acquisition is 128Hz, and detects that the length of data for 16bits, is then set up
The size of data file be：16x128x60x60x24x5=36864000bits, it is therefore desirable to set up 36864000bits big
Small data file, namely the data file include 36864000 data bit.
It should be noted that multiple predetermined number of bits that each acquisition time is corresponded respectively in data file, and often
Two adjacent acquisition times are separated by the length of the detection data between corresponding two predetermined number of bits respectively.Such as in number

Explanation is needed, data acquisition module can be judged the detection data of collection.When above-mentioned gathered data mould
During block operation exception (such as electrode delamination or equipment fault), it is invalid that the detection data of collection are then judged as by the data acquisition module
Data, and the detection data gathered when gathered data module is normally run are judged as valid data.
As in previous example, being initialized as by each of data file data bit after predetermined value, data acquisition module
Normally run, and the detection data of the 1st acquisition time are：A3BD, its corresponding binary data is：
1010001110111101, then above-mentioned detection data are write from the 1st acquisition time corresponding predetermined number of bits, namely certainly
1st predetermined number of bits plays write-in A3BD, and the content update of above-mentioned data file is：1010001110111101,
1111111111111111, its corresponding hexadecimal data is：A3BD, FFFF.Complete above-mentioned 1st acquisition time
After the write-in for detecting data, when data acquisition module under normal operation, collecting the 2nd acquisition time
After detection data, due to the 17th data bit in the 2nd acquisition time above-mentioned data file of correspondence, then from above-mentioned 17th
Data bit plays the detection data of the 2nd acquisition time of write-in, so the like, until being written in into data file all
Valid data.
In addition, as in previous example, it is assumed that during the detection data of data collecting module collected to the 2nd acquisition time,
There is the situation of electrode delamination, now the detection data collected are judged as invalid data by data acquisition module, because the 2nd
The 17th data bit in the acquisition time above-mentioned data file of correspondence, then the 17th data bit is opened in above-mentioned data file
Begin, skip 16 data bit being separated by between the 2nd acquisition time and the 3rd acquisition time, reach data file ending,

As an example it is assumed that the size of default data file is 128bits, the content of default data file is：
A3BD, 88F5, F488, D6F3, FFFF, FD88, E9FE, 88FF.And the length for assuming to detect data is 16bits, then when gathering
Between the number put be 8, and 16 data bit that each acquisition time is corresponded respectively in data file, i.e., the 1st collection
Time point corresponding 16 data bit are expressed as hexadecimal and are：A3BD, namely the detection data of the 1st acquisition time are：
A3BD, the detection data of the 2nd collection point are：88F5, by that analogy, the detection data of the 8th acquisition time are：88FF.
Two adjacent acquisition times are separated by 16 between corresponding two predetermined number of bits respectively.
In step 220, from corresponding predetermined number of bits of first acquisition time, the detection of predetermined length is sequentially read

Imitate in data write-in data file, therefore, when the detection data of acquisition time are invalid data, namely not to data file
The detection data of middle write-in current acquisition time, then the detection data of current acquisition time are in the data file then to be multiple
Predetermined value.When predetermined value is 1, then it represents that be after into hexadecimal data：FFFF.
In such as previous example, after data file is opened, first from the 1st acquisition time (i.e. first acquisition time
Point) corresponding 1st data bit, sequentially reads 16 data bit, namely read the length of detection data, the inspection read
Surveying data is：A3BD, because the detection data are not predetermined values, namely is not FFFF, the detection data is not handled；So
Afterwards from the 2nd acquisition time corresponding 17th data bit, 16 data bit, namely the detection read are sequentially read
Data are：88F5, nor the detection data are not handled by FFFF；So the like, until having read 8 samplings
Untill the detection data or end of data file at time point.
When reading the detection data of above-mentioned 8 sampling times point, when the detection data for reading the 5th sampling time point
When, because the detection data are FFFF, the 5th acquisition time is labeled as invalidated acquisitions time point.

The detection data of current acquisition time really are read from the correspondence position in data file.
The reading pointer points to current acquisition time corresponding predetermined number of bits in the data file.Such as in previous example
In, data acquisition module is when reading the detection data of the 2nd acquisition time, and the reading pointer points to the 17th data bit.
Specifically, after the detection data of predetermined length are read, the reading pointer is moved to next acquisition time
The corresponding predetermined number of bits of point.
Such as in previous example, when completing to read the detection data of the 1st acquisition time from data file, it will read
Fetching pin is moved to the 17th data bit.
Further, step S220 can also include：
The detection data are read from the predetermined number of bits that the reading pointer is pointed to.Such as in previous example, complete
Into after the reading of the detection data of the 1st acquisition time, detection is read from the 17th data bit that reading pointer is pointed to
Data.
In step 230, the corresponding detection data of each acquisition time and reading are exported.
In one example, the corresponding detection data of each acquisition time of output and reading are as follows：
| Acquisition time | T1 | T2 | T3 | T4 | T5 | T6 | T7 | T8 |
| Flag bit | 1 | 1 | 1 | 1 | 0 | 1 | 1 | 1 |
| Detect data | A3BD | 88F5 | F488 | D6F3 | FFFF | FD88 | E9FE | 88FF |
Wherein, T1-T8For acquisition time, flag bit 0 represents that the acquisition time is invalidated acquisitions time point.
Alternatively, methods described also includes：Invalidated acquisitions are determined according to the number at the continuous invalidated acquisitions time point
Interval, and it is interval to export the invalidated acquisitions.
Such as upper table, acquisition time T5Flag bit be 0, namely only acquisition time T5For invalidated acquisitions time point, vacation
If acquisition time T4And T6Flag bit when being also 0, then the number at invalidated acquisitions time point is 3, namely invalidated acquisitions are interval
For T4-T6, while exporting invalidated acquisitions interval T4-T6。
The method for reading data that the present invention is provided, can be labeled to the acquisition time of invalid data, therefore can be with
The acquisition time of invalid data is rapidly and accurately recognized, and when the number at invalidated acquisitions time point is multiple, according to even
