Detailed Description
So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict. It should also be noted that reference to the terms "first \ second \ third" in the embodiments of the present application is only used for distinguishing similar objects and does not represent a specific ordering for the objects, and it should be understood that "first \ second \ third" may be interchanged with a specific order or sequence where possible so that the embodiments of the present application described herein can be implemented in an order other than that shown or described herein.
It should be understood that Micro-patterned gas detectors (MPGD), which are a new type of position sensitive proportional counter and read out using Micro-electrodes, have become the focus of international gas Detector research. MPGD is generally composed of an ionization transition drift region, an avalanche amplification region, and a micro readout electrode. In addition, it is mature to adopt MICRO-Mesh-gas detector (MICROMEGAS), which is a MICRO-structured parallel plate gas detector operating in the proportional range, and the Structure can be regarded as that the gas detector is divided into two asymmetric parts by a Mesh grid film: the region with larger gap is called drift region, and the region with smaller gap is called avalanche amplification region. Thus, since the gas detector has good spatial and temporal resolutions, it is widely used in various application fields such as high-energy physics, nuclear detection, national economy, and the like as a charged particle detector.
In the case of a microstructure gas detector with position resolution (such as MICROMEGAS), binary encoding can be used for encoding readout, and although this encoding scheme can save a large number of electronic channels, it can only recognize that one readout unit is triggered in one event/case. However, in general, in the event detected by using MICROMEGAS, several readout units near the triggered readout unit often have small signals with certain amplitudes, so that MICROMEGAS with a large area often has a plurality of readout units triggered in one event, while the conventional coding scheme is that only one readout unit can be triggered in one event. Thus, the conventional connection of one readout unit using one electronic channel results in a large number of electronic channels, and the use of a large number of multi-channel integrated electronics results in high detection cost.
Based on this, the embodiments of the present application provide a packet coding method, and the basic idea of the method is: determining the number n of reading units included in the reading electrode; wherein n is an integer greater than zero; dividing the n reading units into K groups, and respectively encoding the reading units in each group of the K groups to obtain respective encoding results of the K groups; k is an integer larger than zero, and the value of K is in an incidence relation with a reading unit threshold value which can be triggered by the reading electrode in a single event; and respectively carrying out position decoding according to the respective encoding results of the K groups, and determining the physical position of each group of the K groups for triggering the reading unit. Therefore, by using a block coding reading mode, the capacity of identifying the triggering of a plurality of reading units can be realized in one event, the number of electronic reading channels can be reduced by matching with a corresponding coding scheme, the detection cost is reduced, and the position resolution capacity of the gas detection equipment can be ensured.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
In an embodiment of the present application, referring to fig. 1, a flowchart of a block coding method provided in an embodiment of the present application is shown. As shown in fig. 1, the method may include:
s101: the number n of read-out elements comprised by the read-out electrode is determined.
It should be noted that the block coding method provided by the embodiment of the present application may be applied to a block coding apparatus, or a gas detection device integrated with the apparatus. In the embodiments of the present application, the gas detection device may also be referred to as a gas detector; in one particular example, the gas detection device may be referred to as MICROMEGAS, but is not particularly limited.
It should also be noted that for the gas detection device, it is first necessary to determine the number n of sensing cells in the sensing electrode. In some embodiments, the determining the number of readout cells n included in the readout electrode may include: acquiring a reading electrode; and analyzing the reading electrode according to a preset reading mode, and determining the number n of the reading units of the reading electrode in the current reading plane.
In the embodiment of the application, n is an integer greater than zero.
Further, in some embodiments, the preset readout mode may include at least one of the following: a one-dimensional strip-like readout mode and a two-dimensional block-like readout mode.
That is, the readout electrode can perform readout in a one-dimensional stripe readout manner, where each anode stripe can be regarded as a readout unit; in addition, the readout electrode can also be read out in a two-dimensional block readout manner, and each square dot or Pixel (Pixel) can be regarded as a readout unit. For example, a one-dimensional stripe readout mode is taken as an example, the typical electrode width of the one-dimensional stripe readout mode is 200-400 um, and the gap between the electrodes is 80-100 um. For example, for a readout electrode with an active area of 10cm × 10cm, in the case of an electrode width of 250um and a gap of 100um, the number n of readout cells that can be determined at this time will be 280.
In this way, a demand analysis for the readout electrodes can determine the number n of readout cells in the current readout plane, where n is an integer greater than zero.
S102: dividing the n reading units into K groups, and respectively encoding the reading units in each group in the K groups to obtain respective encoding results of the K groups; and K is an integer larger than zero, and the value of K is associated with the threshold value of the reading unit which can be triggered by the reading electrode in a single event.
It should be noted that, in the related art, only one readout unit can be recognized to be triggered in one event, that is, only one readout unit can be triggered in one event; in order to increase the number of the readout units that can be triggered in one event, the embodiment of the present application provides a block coding method, specifically, n readout units are grouped, and are divided into K groups, and then the readout units in each of the K groups are respectively coded.
It should be noted that, if the upper limit of the number of the sensing units that can be triggered in one encoding method in one event is 1, and the n sensing units are divided into K groups, the number of the sensing units that can be triggered in one event is increased to K. In other words, the value of K is correlated to the threshold value of the sense unit that the sense electrode can trigger in a single event. Thus, in some embodiments, the method may further comprise:
determining a threshold value N of a sensing unit which can be triggered in a single event of a sensing electrode;
setting the value of K to be larger than or equal to a threshold value N of a reading unit; wherein N is an integer greater than zero.
That is, first, the upper limit value of the readout units, that is, the value of N, that the readout electrodes can trigger simultaneously in a single event can be determined, and then the number K of groups into which the N readout units are divided is further determined, and accordingly, the number of readout units in each group can also be determined.
In some embodiments, when the value of K is equal to N, the dividing the N readout units into K groups may further include: the number of read-out units in each of the K groups is determined to be equal to N/N. Thus, if the value of N is equal to 1, the N readout units may be divided into 1 group at this time, that is, the N readout units in the group are encoded; or, if the value of n is equal to 1, only one readout unit exists at this time, and the readout unit threshold value that can be triggered simultaneously in a single event is also 1, then it can be regarded as a case that the one readout unit is divided into 1 group; therefore, the block coding method of the embodiment of the present application can also be applied to an application scenario with only one readout unit.
Further, in some embodiments, the encoding the readout units in each of the K groups to obtain the respective encoding results of the K groups respectively may include:
based on the ith group in the K groups, coding N/N reading units in the ith group by using a preset coding mode to obtain a coding result of the ith group; wherein i is an integer greater than zero and less than or equal to K.
In a specific example, the encoding N/N readout units in the ith group by using a preset encoding method to obtain an encoding result of the ith group may include:
and encoding the N/N reading units in the ith group by using a preset encoding mode, outputting m paths of electronic signals, and determining the m paths of electronic signals as the encoding result of the ith group.
In another specific example, the encoding N/N readout units in the ith group by using a preset encoding method to obtain an encoding result of the ith group may include:
encoding the N/N reading units in the ith group by using a preset encoding mode, and outputting m paths of electronic signals;
amplifying the m paths of electronic signals through an amplifier module to obtain m paths of amplified signals;
and sampling the m paths of amplified signals through an analog-to-digital conversion module to obtain m paths of sampling signals, and determining the m paths of sampling signals as the coding result of the ith group.
The preset encoding method may be a dichotomy encoding method, or may be other encoding methods, and the embodiment of the present application is not particularly limited. In addition, for the K groups of reading units, the encoding modes used by each group may be the same or different, that is, the K groups of reading units after grouping are not limited to one encoding mode, and the encoding mode of each group is optional.
It should be further noted that, in the embodiments of the present application, m is an integer greater than zero and less than N/N. In this way, after grouping the n read-out cells, a preset encoding scheme can be used for the read-out cells within each group. Taking the ith group as an example, and assuming that the preset coding mode of the ith group is a dichotomy coding mode, dichotomy coding is performed on N/N reading units in the ith group, and the output electronic signal is m paths at this time; since m is smaller than N/N, the purpose of reducing the number of electronic read-out channels can be achieved.
Exemplarily, assuming that the number of the readout units in the ith group is 4, the binary code can be output by 2 electronic signals; assuming that the number of the readout units in the ith group is 6, the readout units can be output through 3 paths of electronic signals after binary coding; in the encoding process, each path of electronic signal carries the original physical position information of the reading unit, so that the physical position of the triggering reading unit in the ith group can be derived by reverse estimation according to the electronic signals.
It should be noted that, for the gas detection device, it may further include an amplifier (Amplifiers) module and an Analog to Digital Conversion (ADC) module. Therefore, for the electronic signals output after being coded, the electronic signals can be amplified by the amplifier module firstly, and then the sizes of the electronic signals are recorded by sampling of the analog-to-digital conversion module, so that the coding result of each group is obtained.
S103: and respectively carrying out position decoding according to the respective encoding results of the K groups, and determining the physical position of each group of the K groups for triggering the reading unit.
It should be noted that after the coding results of each group are obtained, the physical positions of the trigger readout units in each group can be reversely deduced by performing position decoding according to the coding results. Specifically, in some embodiments, the separately performing position decoding according to the respective encoding results of the K groups to determine the physical position of each group of the K groups triggering the readout unit may include:
determining m paths of sampling signals according to the coding result of the ith group;
and determining a target physical position corresponding to the m paths of sampling signals according to the m paths of sampling signals and the mapping relation between the physical positions and the electronic signals, and determining the target physical position as the physical position of the ith group of trigger reading units.
That is, taking the ith group as an example, according to the encoding result of the ith group, m paths of encoded sampling signals, that is, m paths of encoded electronic signals, may be determined, and then according to the mapping relationship between the physical position and the electronic signals, the corresponding target physical position may be determined, where the target physical position is the physical position where the ith group triggers the readout unit.
For example, as shown in fig. 2, assuming that the number of readout units in the ith group is 4, the dichotomy coding can be performed using 2 electronic signals. The four readout cells are arranged in a2 × 2 array, and have position numbers of 1, 2, 3, and 4, respectively. According to the coding scheme of the dichotomy, a first path of electronics is connected with two reading units with the numbers of 1 and 3, and a second path of electronics is connected with two reading units with the numbers of 1 and 2. If the first path of electronics has signals and the second path of electronics does not have signals, the hitting position is a reading unit with the code of 3; if neither the first nor the second path has a signal, at this point depending on the specifics of the MICROMEGAS gas detector, an over-threshold signal may be present on other structures (e.g. a wire mesh), but since the electronic channel does not detect the over-threshold signal, it may be concluded that the hit location is the read-out unit numbered 4 (which is not connected to any electronic channel).
The embodiment provides a group coding method which is applied to a gas detection device. Determining the number n of reading units included in the reading electrode; wherein n is an integer greater than zero; dividing the n reading units into K groups, and respectively encoding the reading units in each group in the K groups to obtain respective encoding results of the K groups; k is an integer larger than zero, and the value of K is in an incidence relation with a reading unit threshold value which can be triggered by a reading electrode in a single event; and respectively carrying out position decoding according to the respective encoding results of the K groups, and determining the physical position of each group of the K groups for triggering the reading unit. Therefore, by using a block coding reading mode, the capacity of identifying the triggering of a plurality of reading units can be realized in one event, the number of electronic reading channels can be reduced by matching with a corresponding coding scheme, the detection cost is reduced, and the position resolution capacity of the gas detection equipment can be ensured.
In another embodiment of the present application, based on the same inventive concept as the foregoing embodiment, refer to fig. 3, which shows a detailed flowchart of a block coding method provided in an embodiment of the present application. As shown in fig. 3, the detailed flow includes:
s301: the number n of read-out elements comprised by the read-out electrode is determined.
S302: a threshold value N of the sense unit that can be triggered in a single event is determined.
S303: and (3) coding the N/N reading units in each group by using a dichotomy coding mode to obtain a coding result of each group.
S304: and decoding to obtain the physical position of each group of trigger reading units according to the encoding result of each group.
It is understood that the read method using block coding of the embodiments of the present application may be capable of identifying multiple read unit triggers in one event. Specifically, taking a dichotomy coding method as an example, first, an upper limit value (or referred to as "threshold value") N for simultaneously triggering a plurality of readout units in an experiment is estimated; all the read-out units (N total) using the binary coding are then divided into N groups, and the number of read-out units using the binary coding within each group is then N/N. In addition, in the embodiment of the application, the reading units can be properly arranged according to actual requirements, so that a better reading effect is obtained.
Specifically, for the binary encoding, refer to fig. 4, which shows a schematic diagram of a one-dimensional block encoding readout technology provided in the embodiment of the present application. As shown in fig. 4, this coding scheme is more suitable for asymmetric binary coding scheme, rather than the binary coding scheme mentioned in the foregoing embodiments, fig. 4 may be used to illustrate a block coding scheme, but not a binary coding scheme, and the coding scheme of each group is arbitrarily selectable, and is not limited to one coding scheme. In fig. 4, the stripe (clip) above the sense electrode is a sense unit, such as sense unit (clip) a1, sense unit (clip) B1, sense unit (clip) C1, sense unit (clip) a2, …, sense unit (clip) An, sense unit (clip) Bn, sense unit (clip) Cn; here it is divided into three groups: the reading unit (Strip) A1, the reading units (Strip) A2, … and the reading unit (Strip) An form a first group (group A) for coding and merging, the reading unit (Strip) B1, the reading units (Strip) B2, … and the reading unit (Strip) Bn form a second group (group B) for coding and merging, the reading unit (Strip) C1, the reading units (Strip) C2, … and the reading unit (Strip) Cn form a third group (group C) for coding and merging, the coded electronic signals enter An amplifier (Amplifiers) module through An electronic channel, and then the size of the signals is recorded through An Analog Digital Conversion (ADC) module. In addition, it is required toIt is noted that the curve above the read-out unit represents electrons (e)-) Under the action of a strong electric field, the physical distribution curve of the signal amplitude when the gas detection device generates electron avalanche is exemplified.
In one possible implementation, assuming that the readout electrode has a total of 12 readout cells, two sensing bars with different widths can be added on the back of each readout cell to divide the signal of each readout cell into two unequally. At this time, the 12 reading units are divided into two groups, namely the odd numbers of the reading units are one group, and the even numbers of the reading units are the other group; the odd-numbered groups can be coded and combined through three electronic signals of x1, x2, x3 and the like, and the even-numbered groups can be coded and combined through three electronic signals of y1, y2, y3 and the like. Thus, in the case of at most two adjacent read-out units being triggered simultaneously, there are only two output signals per set of electrical signals at this time. Specifically, by comparing the magnitude relationship of two paths of signals in x1, x2 and x3, the physical position of the trigger reading unit in the 6 paths of odd-numbered numbers can be determined; by comparing the magnitude relationship of the two signals in y1, y2 and y3, the physical position of the trigger readout unit in the 6 even-numbered channels can be determined.
It should be noted that, in the above implementation, although the packet coding method can also reduce the number of electronic readout channels, a plurality of readout units that are triggered simultaneously need to be consecutive, and the highest triggered readout unit threshold value needs to be greater than 1. In the embodiment of the present application, another possible implementation manner is also provided, and the specific implementation steps are as follows:
(a) determining the number n of read-out units in the current read-out plane of the read-out electrode through demand analysis;
(b) determining the number N of the highest triggerable reading units in a single event in an experiment;
(c) encoding the N/N read-out units in each group by using a dichotomy;
(d) the physical position of each group of trigger readout units is derived from the corresponding physical position map and the electrical signal back-extrapolation.
It is noted that in this implementation a plurality of read-out elements that are triggered simultaneously need not be consecutive, and that only one read-out element may trigger. In addition, the dichotomy coding reading mode of the original N reading units is divided into N groups, so that the number of the reading units which are triggered simultaneously in one event can be increased to N. Thus, for N read units, the dichotomy coding is used and the division into N groups is required (N log)2 n-N log2N) electronic channels.
Illustratively, if the readout electrodes have a total of 12 readout cells, the 12 readout cells can be divided into two groups; then, position bisection is carried out on 6 reading units in each group, and the coded signals are output through 3 paths of electronic signals. Because each path of electronic signal carries the original physical position information of the reading unit, the physical position of the triggering reading unit in the group can be derived by reverse estimation according to the 3 paths of electronic signals and the mapping relation between the physical position and the electronic signal.
The specific implementation of the foregoing embodiment is elaborated through the foregoing embodiment, and it can be seen that through the technical solution of the foregoing embodiment, a block coding read-out manner is used, which not only can have the capability of identifying the trigger of multiple read-out units in one event, but also can reduce the number of electronic read-out channels in cooperation with a corresponding coding scheme, thereby reducing the detection cost, and meanwhile, can ensure the position resolution capability of the gas detection device.
