Therefore, below the detailed description of the embodiments of the invention for providing in the accompanying drawings is not intended to limit claimed
The scope of the present invention, but be merely representative of the present invention selected embodiment.It is based on embodiments of the invention, people in the art
The every other embodiment obtained on the premise of creative work is not made by member, belongs to the scope of protection of the invention.
It should be noted that：Similar label and letter represent similar terms in following accompanying drawing, therefore, once a certain Xiang Yi
It is defined in individual accompanying drawing, then in subsequent accompanying drawing which further need not be defined and be explained.Meanwhile, the present invention's
In description, term " first ", " second " etc. are only used for distinguishing description, and it is not intended that indicating or hint relative importance.
Fig. 1 is refer to, Fig. 1 is a kind of flow chart of signal base line processing method provided in an embodiment of the present invention.The side
Method specifically includes step S100, obtains the sampled data obtained after pulse signals are sampled；Step S200, adopts to acquisition
Sample data carry out baseline calculating, obtain the first baseline value；First baseline value is carried out baseline drift differentiation by step S300,
Differentiate that result obtains the second baseline value based on the baseline drift；Step S400, adjusts the arteries and veins based on second baseline value
The baseline of signal is rushed, the pulse signal after simultaneously output adjustment is obtained.
Wherein, step S100, obtains the sampled data obtained after pulse signals are sampled, specifically includes：To receiving
To pulse signal carry out multiple repairing weld and obtain sampled data, the sampled data includes the N number of sampling number after sampling every time
According to.
Specifically, when the pulse signal of input is detected, at this moment the pulse signal to being input into carries out multiple repairing weld, samples
Frequency can be 100MHZ, can gather N number of sample point data every time, and N can be 16384 or 32768 sample point datas, here
Sample point data be not limited only to 16384 or 32768, it is also possible to carry out the sampling number for selecting other numbers as needed
According to each sample point data is digital value, repeats multiple repairing weld, and in the present embodiment, pulse signals carry out 1024 samplings
After obtain sampled data.
Step S200, carries out baseline calculating to the sampled data for obtaining, obtains the first baseline value, refer to Fig. 2, and Fig. 2 is
The flow chart of another kind of signal base line processing method provided in an embodiment of the present invention, step S200 (such as Fig. 1) specifically include step
S210 and step S220.
Step S210, obtains the sample point data minimum of a value in the N number of sample point data after each sampling, obtains many
Individual sample point data minimum of a value.
Step S220, carries out mean value process to the plurality of sample point data minimum of a value, obtains the first baseline value.
Specifically, 16384 or 32768 sample point datas to being gathered in step S100 (such as Fig. 1) be compared or
Sequence, finally takes a minimum of a value in the sample point data for being gathered every time, and minimum of a value here is referred in sample point data
Digital value minimum of a value, so every time sampling can use a minimum of a value, carries out 1024 samplings and can obtain 1024 minimum of a values, right
This 1024 minimum of a values carry out mean value process, and mean value process here is understood that：Mean value refers to arithmetic mean of instantaneous value, i.e.,
The summation of 1024 minimum of a values, then by gained and value can obtain mean value divided by 1024, the mean value of gained is used as first
Baseline value is exported.
Fig. 1 is continued referring to, first baseline value is carried out baseline drift differentiation, based on the baseline by step S300
Drift differentiates that result obtains the second baseline value.
Specifically, by the mean value calculated in step S200, that is, the first baseline value and the reference base for pre-setting
Line value is compared, if the first baseline value is bigger than the reference baseline value for pre-setting, then just deduct the first baseline value pre-
The reference baseline value for first arranging, the difference for obtaining is used as the second baseline value；If the first baseline value is than the reference baseline that pre-sets
Value is little, and the reference baseline value for pre-setting is deducted the first baseline value, and the difference for obtaining is used as the second baseline value；If the first baseline
Value is equal with the reference baseline value for pre-setting, then the reference baseline value for pre-setting is deducted the first baseline value, is obtained
Difference is used as the second baseline value；It should be noted that " big ", " little ", " equal " here refers to comparison numerically.
Here the second baseline value for obtaining is the data signal for carrying the second baseline value.
Step S400, based on the baseline that second baseline value adjusts the pulse signal, after obtaining simultaneously output adjustment
Pulse signal.
Because sample frequency is 100MHZ, that is, 12bit precision, the amplitude range of pulse signal input can be 0-
2V, that is to say, that magnitude of voltage 2V is divided into 212, then minimum scale unit is about 0.5mV, and the reference baseline value for pre-setting can
Think 0.5mV-10mV, best effect can be 0.5mV.
Specifically, second baseline value is the analog signal for carrying the second baseline value, and the second baseline value is pulse signal
Need the amplitude of adjustment, it will be understood that, for example, the reference baseline value that pre-sets is 0.5mV, and the first baseline value is
0.3mV, then the second baseline value is just 0.2mV, if one of amplitude of pulse signal is 0.6mV, at this moment 0.6mV is more than
0.5mV, so need to deduct baseline value 0.2mV；If one of amplitude of pulse signal is 0.4mV, 0.4mV is less than
0.5mV, then be accomplished by carrying out lifting signal amplitude plus baseline value 0.2mV, in this approach adjusting the baseline of pulse signal, so
Afterwards again by the signal output after being adjusted to step S100, that is, the amplitude of pulse signal is adjusted by feedback, entirely
The regulating cycle time is about 1S so that the amplitude of pulse signal is in stable state, so as to improve energy resolution.
The second baseline value in step S400 refers in step S300 be come by the data signal conversion for carrying the second baseline value
The second baseline value of carrying analog signal.

Another kind of signal spectrum schematic diagram of offer.Contrast Fig. 3 and Fig. 4, reference standard of the monokaryon element spectrum as double-core element spectral peak position, letter
Number it is double-core element spectrum 1 without the spectral line for removing Baseline Survey, double-core element spectrum 2 is 1 spectrums that go after baseline of double-core element spectrum, can see
To in Fig. 1, do not go the double-core element spectrum 1 of baseline relative to monokaryon element spectrum, its crest is disturbed and drifts about to the left, and removes baseline
What the crest of double-core element spectrum 2 do not affected substantially by, so this programme carries out real-time baseline restorer process to signal, so that
Signal will not receive ectocine larger in transmitting procedure, and the crest of signal signal in transmitting procedure will not be subject to largely
Skew.
