Fig. 1 is a schematic diagram of a vibration noise compensation device of a high-voltage xenon detector, and the system comprises a high-speed analog-to-digital converter, an FPGA-based digital multichannel pulse amplitude analyzer and data communication.
The algorithm flow of the digital multichannel pulse amplitude analyzer based on the FPGA is shown in fig. 2, a high-voltage xenon detector signal acquired by the high-speed analog-to-digital converter enters the FPGA with high logic resources, and the algorithm in the FPGA mainly comprises: estimation of vibration noise relative change, vibration noise component compensation, sharp-corner pulse forming, amplitude extraction, base line deduction, accumulation judgment, histogram statistics and USB control.
As described above, the sampling rate of the high-speed analog-to-digital converter is greater than 100MSPS, the AD9655 high-speed analog-to-digital converter is adopted in this embodiment, in order to ensure the sampling accuracy, the high-speed analog-to-digital converter is input in a single-ended to differential manner, and the communication manner of the high-speed analog-to-digital converter is designed as an LVDS interface with high-speed transmission capability and low noise in the peripheral circuit.
The digital signal of the high-voltage xenon detector after passing through the high-speed analog-to-digital converter enters an FPGA chip with abundant logic resources, the logic unit of the chip reaches more than 50W, and the FPGA chip adopted in the embodiment is EP4CE115 of Cyclone IV series produced by altera company, and can meet the logic resources required by the algorithm.
As described above, the flow chart of estimation of relative variation of vibration noise is shown in fig. 3, and the flow chart of estimation of relative variation of vibration noise includes threshold triggering, feature extraction, self-adjusting parameters, and mathematical morphological erosion operation on signals. Firstly, triggering a threshold value of a signal of a high-voltage xenon detector, enabling the signal f (x) of the high-voltage xenon detector to enter an FPGA (field programmable gate array), wherein x is a sampling point, and the same is carried out later on, namely different processing of sampling is carried out. Firstly, carrying out derivation processing on a high-voltage xenon detector signal, namely delaying a signal f (x) by one unit to obtain f (x-1), and then subtracting the two values to obtain a derivation result d (x) of the signal, wherein the processing formula is as follows:
d(x)＝f(x)-f(x-1)
setting a trigger threshold value c (x), comparing the sizes of d (x) and c (x), if d (x) is larger than c (x), judging that a pulse exists, and recording the time of a trigger point as t (x). After the trigger pulse is positioned, feature extraction needs to be performed on the signal to estimate the vibration noise relative change component of the detector signal, the feature extraction method is to select t (x) m points before the pulse trigger point, 500 points are adopted for the m value in the embodiment, the m points are sequentially subtracted from the first point of the m points to obtain the relative change trend of the signal, and the relative change trend is used as a structural element g (m) of mathematical morphology corrosion operation, wherein m is 0 to m. The component b (x) for estimating the relative change of the vibration noise of the high-pressure xenon detector is obtained by carrying out mathematical morphology corrosion operation on a signal f (x) of the high-pressure xenon detector, wherein the parameter structural element is g (m), and the mathematical morphology corrosion calculation process formula is as follows:
wherein, the arrival of each pulse can carry out the automatically regulated to the constitutional element, realizes that the constitutional element changes along with the change of pulse signal characteristics to guarantee mathematical morphology and corrode the accuracy of structure, obtain accurate vibration noise relative change composition.
The vibration noise component compensation mainly compensates a high-voltage xenon detector signal f (x) obtained by a high-speed analog-to-digital converter and the relative change b (x) of vibration noise to obtain a high-voltage xenon detector signal v (x) after the vibration noise is primarily compensated, and the formula is as follows:
v(x)＝f(x)-b(x)
as shown in fig. 4 and 5, fig. 4 shows four segments of the high-voltage xenon detector signal before the initial compensation of the vibration noise, and fig. 5 shows four segments of the high-voltage xenon detector signal after the initial compensation of the vibration noise, as can be seen from the figures, the baseline of the signal is affected by the vibration noise and fluctuates continuously before the initial compensation, so that the measurement of the pulse amplitude is affected by the change of the baseline, and the signal of the high-voltage xenon detector after the initial compensation compensates the vibration noise in real time, so that the baseline of the signal is kept stable, and only a slight dc offset exists, which can be compensated again in the subsequent subtraction of the sharp-angled baseline.
And (3) carrying out sharp-angle pulse forming on the high-voltage xenon detector signal after initially compensating the vibration noise to obtain sharp-angle pulses s (x), wherein the Z conversion calculation formula of the sharp-angle pulse forming is as follows:
dk(x)＝v(x)-v(x-k)，
d1(x)＝v(x)-v(x-1)，
p(x)＝p(x-1)+dk)x)-kd1(x-l)，
q(x)＝q(x-1)+m2p(x)，
s(x)＝s(x-1)+q(x)+m1p(x)，
the parameters in the formula include k, l, m1，m2Verified by the embodiment, k determines the length of the sharp-corner pulse forming and is an odd number, l is half of the length of the sharp-corner pulse, i.e. half of k minus 1, m1And m2Ratio of parameters Q ═ m1/m2The amplitude magnification factor of the sharp-angle pulse forming is determined, and in the embodiment, k is 501, l is 250, and m is selected1＝75，m2Because the shape after forming is sharp-horn-shaped, the amplitude can be conveniently and accurately extracted, and the signal-to-noise ratio is good.
As described above, amplitude extraction is to extract the highest amplitude value of the sharp-angled pulse forming signal s (x), by setting the trigger threshold J, when N consecutive values of the sharp-angled pulse forming signal s (x) are greater than J, it is determined that the pulse at this time is valid, and the amplitude value of the valid pulse needs to be extracted, the amplitude extraction method mainly compares the peak values of e data after the trigger point, where the e value adopted in this embodiment is 300, and continuously compares the sizes of adjacent points by using a comparator to obtain the maximum value h (x) as the amplitude value of the sharp-angled pulse forming signal, so that the implementation method is simple, erroneous determination is not likely to occur, and measurement is accurate.
As described above, the baseline subtraction process is as shown in fig. 6, the baseline value of the signal is subtracted from the sharp-corner pulse-shaped amplitude value, the baseline value of the conventional baseline subtraction is a fixed statistical value, here, a continuously adjusted baseline value is used, the signal baseline value is the result of averaging a plurality of points before the sharp-corner pulse is shaped, and the plurality of points are m points and are equal to the length of the structural element. If pulse accumulation occurs and the baseline value between two pulses is less than m points, the last baseline value is continuously used until the baseline value is sufficiently acquired, and the baseline value is not replaced, so that the change of the baseline can be captured in real time, the vibration noise and the direct current offset of the detector signal can be eliminated in real time, and the purpose of stable measurement is achieved.
As mentioned above, the histogram statistical process mainly generates the energy spectrum of the high-voltage xenon detector, and here, a double-end RAM is adopted, one end of the RAM is used for the amplitude height statistics of the high-voltage xenon detector, and the other end of the RAM is used as a data communication port of the USB. In the amplitude height statistics end of the high-voltage xenon detector in the double-end RAM adopted in the embodiment, the amplitude value subjected to baseline deduction is used as an address section of the RAM for inputting, then data of the address is added by one to realize histogram statistics of pulse amplitude height, and in the RAM at the other end of the USB, an address line and a data line of the RAM are directly connected to a control module of the USB, so that data in the double-end RAM can be extracted at any time, and the energy spectrum statistics function is realized.

The high-speed FPGA is selected for processing, data can be processed in parallel, and the problems of high signal frequency and insufficient processing speed of the detector are effectively solved. Meanwhile, the algorithm based on the mathematical morphology corrosion operation consumes a large amount of logic resources, so that the FPGA with rich logic resources is adopted to promote the smooth operation of the algorithm. The processing speed of the digital signal processing module based on the FPGA is matched with that of the high-speed analog-to-digital converter, vibration noise compensation is carried out on an input high-voltage xenon detector signal, and then energy spectrum output is carried out.
