All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, there is provided a flow chart of a gas detector encoding processing method according to embodiment 1 of the present application, which may include, but is not limited to, the following steps:
and S11, determining the number of electronic reading channels according to the number of detector channels of the gas detector.
The electronic readout channel can be understood as: and the channel is connected with the detector channel of the gas detector and is used for reading the signal in the detector channel of the gas detector.
Since the electronics readout channel is a channel for reading signals in the detector channel of the gas detector, the number of electronics readout channels needs to be set according to the detector channel data of the gas detector.
In this embodiment, the determining the number of electronic readout channels according to the number of detector channels of the gas detector may include:
substituting the number of detector channels of the gas detector into a relation I

Of course, the determining the number of electronic readout channels based on the number of detector channels of the gas detector may also include:
substituting the number of detector channels of the gas detector into a relation I
Is calculated to satisfy
Or the said
And one of the values greater than the minimum value is taken as the number of electronic readout channels, dcn representing the number of detector channels of the gas detector.
And S12, constructing at least one Hamiltonian path by taking a plurality of electronic reading channels of the electronic reading channels as vertexes, wherein the edges between every two vertexes in the Hamiltonian path respectively correspond to one detection channel.
The hamiltonian path can be understood as: if a path passes through each vertex only once, then the path is a Hamiltonian path.
In this embodiment, each electronic reading channel is used as a point, and two electronic reading channels are used for electronic readingThe combination of the outgoing channels is taken as a path, and each path corresponds to a detector channel. It can be easily demonstrated that n electronic read channels correspond to
Two of them are combined in disorder. The constraints of gas detector encoding require that the disordered combination of the electronic readout channels corresponding to every two adjacent readout strips is not repeated and occurs at most once. Then, if passing a specific coding mode, it will
The detector channels are uniquely mapped to the n electronic reading channels, so that the maximum code reading of the n electronic reading channels can be realized
A detector channel. Specifically, the encoding problem can be converted into the euler path problem, that is, whether all paths can be drawn in one stroke or not.
Specifically, under the condition of converting the coding problem into the Euler path problem, at least one Hamiltonian path is constructed by taking a plurality of electronic reading channels as vertexes, and one path is ensured to pass through and only pass through each vertex once.
In this embodiment, the process of constructing at least one hamiltonian path by using the plurality of electronic reading channels as vertices may include, but is not limited to:
s121, using the relation II H (k): n-1 → v 0 (k)→v 1 (k)→…→v n-2 (k) And the relation of three
Constructing at least one Hamiltonian path;
n denotes the number of electronic read channels, v i (k) The number of the electronic reading channel is represented, i belongs to (0, 1, \8230; n-2), k belongs to (0, 1, \8230; n-2), and k represents a line number.
Now, the step S121 is illustrated by way of example, for example, n =7, and the constructed hamiltonian path can be referred to in table 1.
TABLE 1
And S13, determining an Euler loop based on at least one Hamiltonian path, wherein the Euler loop passes through each edge only once and passes through each vertex.
In this embodiment, an euler loop is determined based on at least one of the hamiltonian paths, where the euler loop passes through each edge only once, and passes through each vertex, so as to implement deduplication of repeated paths in the hamiltonian paths, and each edge corresponds to only one vertex (i.e., each detector channel corresponds to only one electronics readout channel), and each vertex corresponds to multiple edges (i.e., each electronics readout channel corresponds to multiple detector channels).
In this embodiment, by way of example in step S121, a process of determining an euler loop based on at least one of the hamiltonian paths is described, where as shown in table 1, repeated paths exist in the hamiltonian paths, and after determining the euler loop based on a plurality of hamiltonian paths, the repeated paths are removed from the 21 paths in table 1. The path in the euler loop includes: 6 → 0 → 1 → 5 → 2 → 4 → 3 → 6 → 1 → 2 → 0 → 3 → 5 → 4 → 6 → 2 → 3 → 4 → 0 → 5 → 6.
The Euler circuit, which includes 6 → 0 → 1 → 5 → 2 → 4 → 3 → 6 → 1 → 2 → 0 → 3 → 5 → 4 → 6 → 2 → 3 → 4 → 0 → 5 → 6, can be seen in FIG. 2, where A-G denotes an electronic read channel, A corresponds to 0, B corresponds to 1, C corresponds to 2, D corresponds to 3, E corresponds to 4, F corresponds to 5, G corresponds to 6. Wherein, in the euler loop, 6 → 0 corresponds to the probe channel 1,0 → 1 corresponds to the probe channel 2,1 → 5 corresponds to the probe channel 3,5 → 2 corresponds to the probe channel 4,2 → 4 corresponds to the probe channel 5,4 → 3 corresponds to the probe channel 6,3 → 6 corresponds to the probe channel 7,6 → 1 corresponds to the probe channel 8,1 → 2 corresponds to the probe channel 9,2 → 0 corresponds to the probe channel 10,0 → 3 corresponds to the probe channel 11,3 → 5 corresponds to the probe channel 12,5 → 4 corresponds to the probe channel 13,4 → 6 corresponds to the probe channel 14,6 → 2 corresponds to the probe channel 15,2 → 3 corresponds to the probe channel 16,3 → 1 corresponds to the probe channel 17,1 → 4 corresponds to the probe channel 18,4 → 0 corresponds to the probe channel 19,0 → 5 corresponds to the probe channel 20,5 → 6 corresponds to the probe channel 21.
And S14, taking the corresponding relation between the starting point of the Euler path in the Euler loop and the Euler path as the corresponding relation between the electronic reading channel corresponding to the starting point of the Euler path and the detector channel corresponding to the Euler path, and constructing an encoding table, wherein the encoding table comprises the corresponding relation between a plurality of electronic reading channels and the detector channels corresponding to the electronic reading channels.
In this embodiment, still by way of example in step S13, a description is continued on a correspondence relationship between a starting point of an euler path in the euler loop and the euler path, as a correspondence relationship between an electronic readout channel corresponding to the starting point of the euler path and a detector channel corresponding to the euler path, and based on the euler loop shown in fig. 2, a reference may be made to fig. 3 for an obtained correspondence relationship between the electronic readout channel and the detector channel, as shown in fig. 3, an electronic readout channel G corresponds to detector channels 1, 8, and 15, an electronic readout channel F corresponds to detector channels 4, 13, and 21, an electronic readout channel E corresponds to detector channels 6, 14, and 19, an electronic readout channel D corresponds to detector channels 7, 12, and 17, an electronic readout channel C corresponds to detector channels 5, 10, and 16, an electronic readout channel B corresponds to detector channels 3, 9, and 18, and an electronic readout channel a corresponds to detector channels 2, 11, and 20.
It should be noted that, in a particle detection experiment, a valid signal often hits on several adjacent detector channels and is transmitted to the electronic channel through the detector channel, and we can uniquely determine the hit of the valid signal according to the electronic channel signal. For example, if a particle signal hits on the 7, 8, 9 detector channels, then we will get the corresponding information on the electronic channels D, G, B. It will be appreciated that there are many different travel paths for the same euler loop, and that the coding results obtained for different paths will vary. From a point and back, the path taken forms an Euler loop, the length of which represents the spacing length of the electronic channel on the code. For example, if the circuit returns to point a after passing through points B and C from point a, the length of the circuit is 3, and the corresponding electronic coding interval is 3. When the electronic coding interval is small, it is very easy to generate error decoding, resulting in reduced resolution. As shown in fig. 3, when the particle signal hits at 5, 6, 7 detector channels, the electronic readout is 1,3, 5 channels, and the back-pushed detector hits at 5, 6, 7, 8 channels, a mis-decode occurs, resulting in a reduced detector position resolution. In order to avoid this situation of misinterpretation as much as possible, we should ensure that the length of the smallest loop in the euler path is as large as possible.
In this embodiment, the spacing of successive occurrences of the same electronic readout channel reaches a theoretical maximum.
In the application, at least one Hamiltonian path is constructed by taking a plurality of electronic reading channels of the electronic reading channels as vertexes, edges between every two vertexes in the Hamiltonian path respectively correspond to one detection channel, and an Euler loop is determined from the Hamiltonian path, passes through each edge only once, and passes through each vertex, so that disordered combination of every two adjacent electronic reading channels is not repeated and appears at most once, a group of continuous detector channels is uniquely mapped to one electronic reading channel, multiplexing of the electronic reading channels is realized, and the number of the electronic reading channels is reduced by multiplexing the electronic reading channels.
And the multiplexing rate of each electronics reading channel is the same, the noise is smaller, and the position resolution of the detector is favorably improved.
As another alternative embodiment of the present application, referring to fig. 4, a flowchart of an embodiment 2 of a coding processing method for a gas detector provided in the present application is provided, and this embodiment is mainly an extension of the coding processing method for a gas detector described in the above embodiment 1, as shown in fig. 4, the method may include, but is not limited to, the following steps:
and S21, determining the number of electronic reading channels according to the number of detector channels of the gas detector.
And S22, constructing at least one Hamiltonian path by taking a plurality of electronic reading channels of the electronic reading channels as vertexes, wherein the edges between every two vertexes in the Hamiltonian path respectively correspond to one detection channel.

And S25, reading a signal from a signal reading circuit of the gas detector, searching a detector channel corresponding to an electronic reading channel to which the signal belongs in the coding table, and taking the searched detector channel as a hitting position of the particle detected by the gas detector.

And S26, acquiring the deposition energy information of the particles detected by the gas detector from the signals.
