The microstructure gas detector MPGD is a hot spot for the research of international gas detectors at present, is applied to high-energy physical experiments, and is widely applied to the aspects of high-energy physics, nuclear detection and the like.
MPGD is typically composed of an ionization transition drift region, an avalanche amplification region, and a micro-readout electrode. In order to be able to have a good position resolution in a microstructured gas detector, it is often necessary to integrate electronics for the number of corresponding channels for reading out the signal. However, not all electronic channels can be utilized in one event. In order to make maximum use of the free electronic channels, methods such as stripe reading and code reading have been developed in addition to dot matrix reading in the MPGD reading method. It is common to make the electrodes in one-dimensional or two-dimensional stripes for pixel readout.
The code readout enables the corresponding electronics to be omitted depending on the particular coding method. For example, for a total of n small areas on a plane, pad readout requires n readout electronics, stripe readout requires 2sqrt (n) electronics channels, and existing asymmetric code readout methods require sqrt (n) electronics channels.
At present, in order to improve the performance of the detector to the greatest extent on the basis of ensuring the position resolution capability of the detector, how to reasonably reduce the number of read-out electronic channels is a problem to be solved.
In order to solve the above-mentioned problem, in an embodiment of the present application, after detecting a trigger signal, a trigger channel corresponding to the trigger signal is determined; determining a triggering unit corresponding to the triggering channel based on a mapping relation between a preset reading unit and the channel; wherein the trigger unit is at least one of all the read-out units in the read-out plane; the mapping relation between the preset reading unit and the channel is established based on a binary coding strategy; and determining a trigger position corresponding to the trigger signal according to the mapping relation between the preset reading unit and the position and the trigger unit. Therefore, in the embodiment of the application, the detection equipment can complete the construction of the mapping relation between the preset reading unit and the channel in advance based on the binary coding strategy, so that after the trigger signal is detected, the corresponding trigger position can be accurately positioned by using a small number of electronic channels through the mapping relation between the preset reading unit and the channel, the number of the read electronic channels can be reduced on the basis of ensuring the position resolution capability of the detector, and the performance of the detector is improved.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

Further, in an embodiment of the application, the detection device may be integrated with at least one electronic channel. Wherein at least one electronic channel may be used for reading out the signal.
It will be appreciated that in embodiments of the application, the trigger channel may be one or more of the at least one electronic channels of the detection device integration.
It should be noted that, in the embodiment of the present application, after detecting the trigger signal, the detecting device may determine the electronic channel corresponding to the trigger signal, that is, determine the corresponding trigger channel.
Further, in an embodiment of the application, the detection device may also be integrated with a readout plane, wherein the readout plane may comprise a plurality of readout units.

Further, in the embodiment of the present application, after detecting the trigger signal, the detecting device may determine the signal intensity parameter of the signal included in each electronic channel, and then may determine the electronic channel with the signal intensity parameter greater than the preset intensity threshold as the trigger channel that receives the trigger signal.
In an exemplary embodiment of the present application, fig. 3 is a second schematic implementation flow chart of a positioning method according to an embodiment of the present application, and as shown in fig. 3, after a trigger signal is detected, a method for a detection device to determine a trigger channel corresponding to the trigger signal may include the following steps:
Step 101a, after detecting the trigger signal, determining a signal strength parameter corresponding to each channel.
And step 101b, determining a channel with the signal strength parameter larger than a preset strength threshold as a trigger channel.
In the embodiment of the application, after the trigger signal is detected, when the detection device determines the trigger channel corresponding to the trigger signal, the signal intensity parameter corresponding to each channel can be determined first. And then comparing the signal intensity parameter corresponding to each channel with a preset intensity threshold value to obtain a comparison result, and finally determining the triggering channel corresponding to the triggering signal by using the comparison result.
Further, in an embodiment of the present application, after comparing the signal intensity parameter corresponding to each channel with the preset intensity threshold, if the comparison result of one or more channels is that the signal intensity parameter is greater than the preset intensity threshold, the detection device may determine the one or more channels as triggering channels.
It should be noted that, in the embodiment of the present application, the preset intensity threshold is used to determine whether the electronic channel includes a signal. Correspondingly, if the signal intensity parameter corresponding to one channel is larger than the preset intensity threshold value, the detection equipment can be considered to detect the trigger signal through the channel; if the signal strength parameter corresponding to a channel is less than or equal to the preset strength threshold, then the channel may be considered to have not received the trigger signal.
102, Determining a trigger unit corresponding to the trigger channel based on a mapping relation between a preset read-out unit and the channel; the trigger unit is at least one of all read-out units in the read-out plane, and the mapping relation between the preset read-out units and the channel is established based on a binary coding strategy.
In the embodiment of the application, after detecting the trigger signal and determining the trigger channel corresponding to the trigger signal, the detecting device can determine the trigger unit corresponding to the trigger channel in the read-out plane based on the mapping relation between the preset read-out unit and the channel.
It should be noted that, in an embodiment of the present application, the triggering unit may be at least one of all the readout units in the readout plane in which the detection device is integrated.
It will be appreciated that in embodiments of the present application, the mapping relationship between the preset readout units and the channels may characterize the corresponding connection relationship between each readout unit in the readout plane and the electronic channels. Wherein, a readout unit can be correspondingly connected with at least one electronic channel, and different readout units can be simultaneously connected with the same electronic channel.
It should be noted that, in the embodiment of the present application, the mapping relationship between the preset readout unit and the channel may be a corresponding relationship between the readout unit and the electronic channel, which is established based on a binary code readout policy.
Further, in the embodiment of the present application, before determining the trigger unit corresponding to the trigger channel, the detection device may complete the establishment of the mapping relationship between the preset readout unit and the channel in advance.
It should be noted that, in the embodiment of the present application, in order to reduce the setting of the electronic channels as much as possible, the correspondence between the readout unit and the electronic channels may be determined based on a binary coding manner, so as to obtain the mapping relationship between the preset readout unit and the channels.
It can be understood that, in the embodiment of the present application, fig. 4 is a schematic diagram of a third implementation flow chart of the positioning method according to the embodiment of the present application, as shown in fig. 4, before determining the trigger unit corresponding to the trigger channel based on the mapping relationship between the preset read-out unit and the channel, that is, before step 102, the method for positioning the detection device may further include the following steps:
Step 104, binary encoding is performed based on all the reading units on the reading plane, and the binary number corresponding to each reading unit on the reading plane is determined.
In the embodiment of the application, the detection device can perform binary coding based on all the read-out units on the integrated read-out plane, so that the binary number corresponding to each read-out unit on the read-out plane can be determined.
It will be appreciated that in embodiments of the present application, for each of the read-out elements in the read-out plane, the detection device may first determine the corresponding decimal number for that read-out element and then convert the decimal number to a corresponding binary number. Wherein, the decimal number corresponding to any reading unit is larger than 0.
In the present application, it is assumed that the sensing plane of the probe apparatus includes 6 sensing units, and decimal numbers corresponding to the 6 sensing units are sequentially 1, 2, 3, 4, 5, and 6, and after the decimal numbers are converted into corresponding binary numbers, binary numbers corresponding to the 6 sensing units are sequentially 001, 010, 011, 100, 101, and 110.
Step 105, according to the binary number corresponding to each reading unit, a mapping relation between the preset reading unit and the channel is established.
In the embodiment of the present application, after binary encoding is performed by the detection device based on all the readout units on the readout plane, and the binary number corresponding to each readout unit on the readout plane is determined, the mapping relationship between the preset readout unit and the channel may be established according to the binary number corresponding to each readout unit.
Further, in the embodiment of the present application, the detection device may establish the mapping relationship between the preset readout unit and the channel based on the binary encoding policy. Specifically, the detection device may establish the mapping relationship between the preset readout unit and the channel based on the numerical value of each bit in the binary number of each readout unit.
Alternatively, in the present application, when establishing a mapping relationship between a preset readout unit and a channel, the detection device may correspond a readout unit with a value of 1 in a certain bit in the binary number to one channel; and (3) corresponding the reading unit with the value of 1 in the other bit in the binary number to the other channel, and so on, so that the corresponding relation between the reading unit and the channel can be determined, and the establishment of the mapping relation between the preset reading unit and the channel is completed.
Further, in an embodiment of the present application, fig. 5 is a schematic diagram showing a flow chart for implementing the positioning method according to the embodiment of the present application, as shown in fig. 5, after binary encoding is performed based on all the readout units on the readout plane, and after determining the binary number corresponding to each readout unit on the readout plane, that is, after step 104, the method for positioning the detection device may further include the following steps:
Step 106, determining the number N of channels according to the binary digit number N of the binary number; wherein N is an integer greater than or equal to 1.
In the embodiment of the present application, after the detecting device performs binary encoding based on the all the readout units on the readout plane and determines the binary number corresponding to each readout unit on the readout plane, the detecting device may further determine, according to the binary number N of the binary number, that the number of channels to be used is N, that is, N electronic channels need to be used. Wherein N is an integer greater than or equal to 1.
It can be understood that, in the embodiment of the present application, when the mapping relationship between the preset readout unit and the channels is established based on the binary encoding strategy, one channel is set corresponding to the readout unit with the value of 1 of a certain bit in the binary number, so that the number of bits of the binary number of the readout unit is the same as the number of channels, that is, the number of bits of the binary number can determine the number of electronic channels to be set.
Illustratively, in the present application, assuming that the detecting apparatus is integrated with 16 readout units, the binary numbers corresponding to the 16 readout units may be from 00001 to 10000, that is, the number of bits of the binary numbers of the readout units is 5, so that the number of channels may be determined to be 5.
Accordingly, in the embodiment of the present application, when the detecting device establishes the mapping relationship between the preset readout unit and the channel based on the value of each bit in the binary number, the mapping relationship between the readout unit with the value of the mth bit being 1 in the binary number and the mth channel in the N channels may be determined, so that the mapping relationship between the preset readout unit and the channel may be obtained. Wherein m is an integer greater than 0 and less than or equal to N.
For example, in the embodiment of the present application, assuming that N has a value of 5, that is, the number of bits of the readout unit and the number of channels are both 5, the detection device may correspond to the first channel the readout unit having the value of 1 in the first bit in the binary code, to the second channel the readout unit having the value of 1 in the second bit in the binary code, to the third channel the readout unit having the value of 1 in the third bit in the binary code, to the fourth channel the readout unit having the value of 1 in the fourth bit in the binary code, and to the fifth channel the readout unit having the value of 1 in the fifth bit in the binary code.
It will be appreciated that in embodiments of the present application, the order of the digits in the binary numbers may be from low to high, or from high to low, i.e., the first digit in the binary number may refer to the highest digit or the lowest digit.
It can be seen that, in the embodiment of the present application, in the mapping relationship between the preset readout units and the channels established based on the binary coding strategy, the first path of electronic channel corresponds to the readout unit with the value of 1 of the highest bit in all the binary numbers, the second path of electronic channel corresponds to the readout unit with the value of 1 of the next highest bit in all the binary numbers, and so on, and the last path of electronic channel corresponds to the readout unit with the value of 1 of the lowest bit in all the binary numbers.
Illustratively, in the embodiment of the present application, assuming that the detecting apparatus is integrated with 16 readout units, N has a value of 5, that is, the number of bits of the readout units and the number of channels are both 5, among the 16 readout units, the readout unit with binary number 10000 may correspond to the first channel, the readout unit with binary number 00101 may correspond to the third channel and the fifth channel at the same time, the readout unit with binary number 00111 may correspond to the third channel, the fourth channel, and the fifth channel at the same time, and the readout unit with binary number 00001 may correspond to the fifth channel.
Further, in the embodiment of the present application, fig. 6 is a schematic diagram of a flow chart of implementation of the positioning method according to the embodiment of the present application, as shown in fig. 6, after the mapping relationship between the preset reading units and the channels is established according to the binary numbers corresponding to each reading unit, that is, after step 105, the method for positioning the detection device may further include the following steps:
and 107, respectively connecting the N channels with all the reading units according to the mapping relation between the preset reading units and the channels.
In the embodiment of the present application, after determining the correspondence between all the readout units and the N channels according to the N-bit binary numbers corresponding to each readout unit, that is, after establishing the mapping relationship between the preset readout unit and the channels based on the binary coding strategy, the detection device may connect the N channels with all the readout units according to the mapping relationship between the preset readout unit and the channels.
Optionally, in the embodiment of the present application, based on the mapping relationship between the preset readout units and the channels, the first electronic channel may be connected to the readout unit with the value of 1 of the highest bit in all the binary numbers, the second electronic channel may be connected to the readout unit with the value of 1 of the next highest bit in all the binary numbers, and so on, and the last electronic channel may be connected to the readout unit with the value of 1 of the lowest bit in all the binary numbers.
It can be understood that in the embodiment of the present application, since the N channels are respectively connected to all the readout units according to the mapping relationship between the preset readout units and the channels, when one or more readout units are triggered, the channels correspondingly connected to the one or more readout units can detect the corresponding trigger signals; otherwise, if the trigger signal is detected in the channel, it can be determined that the readout unit corresponding to the channel is triggered based on the mapping relationship between the preset readout unit and the channel.
That is, in the embodiment of the present application, after determining the trigger channel corresponding to the trigger signal, the detection device may further determine one or more readout units corresponding to the trigger channel, that is, determine the trigger unit corresponding to the trigger signal, based on the mapping relationship between the preset readout units and the channel.
In the present application, assuming that the third channel and the fifth channel in the N channels of the trigger channel bit corresponding to the trigger signal are determined, it may be determined that the binary number of the trigger unit corresponding to the trigger channel is 00101, that is, the readout unit with the binary number 00101 is the trigger unit corresponding to the trigger signal.
Step 103, determining a trigger position corresponding to the trigger signal according to the mapping relation between the preset reading unit and the position and the trigger unit.
In the embodiment of the application, after the detection device determines the trigger unit corresponding to the trigger channel based on the mapping relation between the preset read-out unit and the channel, the trigger position corresponding to the trigger signal can be further determined according to the mapping relation between the preset read-out unit and the position and the trigger unit.
It can be appreciated that, in the embodiment of the present application, the mapping relationship between the preset readout unit and the position may be used to determine the physical position corresponding to any one readout unit.
Alternatively, in the embodiment of the present application, in the mapping relationship between the preset readout unit and the position, the mapping relationship may be expressed as a correspondence relationship between the decimal number of the readout unit and the physical position, or may also be expressed as a correspondence relationship between the binary number of the readout unit and the physical position. For example, assuming that the sensing plane of the detection device integration includes 6 sensing units, the following tables 1 and 2 may respectively be the mapping relationship between preset sensing units and positions:
TABLE 1
Reading unit Position of
Reading unit 1 Physical location 1
Reading unit 2 Physical location 2
Reading unit 3 Physical location 3
Reading unit 4 Physical location 4
Reading unit 5 Physical location 5
Reading unit 6 Physical location 6
TABLE 2
The mapping relationship between the preset read-out unit and the position shown in table 1 may be used to determine the corresponding relationship between the decimal number and the physical position of the read-out unit, and the mapping relationship between the preset read-out unit and the position shown in table 2 may be used to determine the corresponding relationship between the binary number and the physical position of the read-out unit.
For example, according to the present application, based on the above table 1 or table 2, if it is determined that the trigger unit corresponding to the trigger signal is the read-out unit 2 (i.e., the read-out unit 010), it may be determined that the corresponding trigger position is the physical position 2 based on the mapping relationship between the preset read-out unit and the position.
Further, in the embodiment of the present application, fig. 7 is a schematic diagram of an implementation flow of the positioning method according to the embodiment of the present application, as shown in fig. 7, before determining, according to the mapping relationship between the preset reading unit and the position and the trigger unit, the trigger position corresponding to the trigger signal, that is, before step 103, the method for positioning the detection device may further include the following steps:
And 108, analyzing and processing the read-out plane to obtain all read-out units in the read-out plane.
In an embodiment of the application, the detection device may perform an analysis process on the integrated readout plane in advance, so as to obtain all the readout units in the readout plane.
It will be understood that in the embodiment of the present application, when the readout plane is analyzed, the detection device may select any analysis mode, for example, one-dimensional analysis, two-dimensional analysis, and the like, and the number of readout units obtained after the analysis may be any, and the sizes and shapes of different readout units may be the same or different, which is not particularly limited to the present application.

In an embodiment of the present application, after the detecting device performs binary encoding based on the all the readout units on the readout plane, and determines the N-bit binary numbers of the readout units, it may further determine that the number of channels to be used is N, that is, N electronic channels need to be used.
Illustratively, in the present application, assuming that the detecting apparatus is integrated with 4 readout units, the number N of bits of the binary number corresponding to the 4 readout units is 3, so that the number of channels can be determined to be 3.
Step 204, according to the N-bit binary number of the readout unit, a mapping relationship between the preset readout unit and the channel is constructed.
In the embodiment of the application, after binary coding is performed on the basis of all the reading units on the reading plane and the binary number corresponding to each reading unit on the reading plane is determined, the detection equipment establishes the mapping relation between the preset reading units and the channels according to a binary coding strategy. Specifically, the detection device may establish the mapping relationship between the preset readout unit and the channel based on the value of each bit in the N-bit binary number of each readout unit.

And then comparing the signal intensity parameter corresponding to each channel with a preset intensity threshold value, and if the comparison result of one or more channels in the N channels is that the signal intensity parameter is greater than the preset intensity threshold value, determining the one or more channels as triggering channels by the detection equipment.
Step 207, determining a trigger unit by using a mapping relation between a preset reading unit and a channel.
In the embodiment of the application, after detecting the trigger signal and determining the trigger channel corresponding to the trigger signal, the detecting device can determine at least one reading unit corresponding to the trigger channel in the reading plane, namely determine the trigger unit corresponding to the trigger signal, based on the mapping relation between the preset reading unit and the channel.
In the present application, assuming that the trigger channel corresponding to the trigger signal is determined to be the second channel and the third channel of the N (n=3) channels, it may be determined that the binary number of the trigger unit corresponding to the trigger channel is 011, that is, the readout unit 3 with the binary number of 011 is the trigger unit corresponding to the trigger signal.
Step 208, determining the trigger position by using the mapping relation between the preset reading unit and the position.
In the embodiment of the application, after the detection device determines the trigger unit corresponding to the trigger channel based on the mapping relation between the preset read-out unit and the channel, the trigger position corresponding to the trigger signal can be further determined according to the mapping relation between the preset read-out unit and the position and the trigger unit.
In summary, by the positioning method provided by the application, in a one-time trigger event, if one readout plane includes n readout units, the number of electronic channels required for positioning the trigger signal can be reduced to log 2 n paths, so that the number of electronic channels can be effectively saved.
The embodiment of the application provides a positioning method, which comprises the steps of determining a trigger channel corresponding to a trigger signal after the trigger signal is detected; determining a triggering unit corresponding to the triggering channel based on a mapping relation between a preset reading unit and the channel; wherein the trigger unit is at least one of all the read-out units in the read-out plane; the mapping relation between the preset reading unit and the channel is established based on a binary coding strategy; and determining a trigger position corresponding to the trigger signal according to the mapping relation between the preset reading unit and the position and the trigger unit. Therefore, in the embodiment of the application, the detection equipment can complete the construction of the mapping relation between the preset reading unit and the channel in advance based on the binary coding strategy, so that after the trigger signal is detected, the corresponding trigger position can be accurately positioned by using a small number of electronic channels through the mapping relation between the preset reading unit and the channel, the number of the read electronic channels can be reduced on the basis of ensuring the position resolution capability of the detector, and the performance of the detector is improved.
Based on the above embodiment, a positioning method is provided in a further embodiment of the present application, fig. 11 is a schematic diagram of an implementation framework of the positioning method, and as shown in fig. 11, the positioning method provided in the embodiment of the present application is a positioning method based on a signal coding readout mode, and mainly includes the steps of coding a readout unit and calculating the number of channels required, determining a correspondence between the readout unit and the channels according to the binary number of the coded readout unit (a mapping relationship between a preset readout unit and the channels), determining a trigger unit corresponding to a trigger channel of a detected trigger signal through decoding processing, and determining a physical position of the trigger signal.
Specifically, in the embodiment of the present application, the detecting device may first calculate all the readout units required for the readout plane, and perform binary encoding based on all the readout units, to determine the binary number corresponding to each readout unit.
It will be appreciated that in embodiments of the present application, for an N-bit binary number, the detection device may determine that N electronic channels are used. I.e. the number of bits of the binary number corresponding to the read-out unit is the same as the number of electronic channels.
Further, in the embodiment of the present application, after determining the binary number corresponding to each readout unit, the detection device may complete establishment of the mapping relationship between the preset readout unit and the channel based on the binary coding strategy. Specifically, the detection device may use the first path of electronic channel to connect the readout unit with the value 1 of the highest bit in all binary numbers; a second path of electronic channel is used for connecting the reading units with the numerical value of 1 of the next highest digit in all binary numbers; the above operations are sequentially performed until the last electronic channel is used to connect the readout unit with the value 1 of the lowest digit among all binary numbers.
For example, in the embodiment of the present application, fig. 12 is a schematic diagram of mapping relationship between a readout unit and a channel, and as shown in fig. 12, assuming that a readout plane integrated by a detection device includes 4 readout units, i.e., a readout unit a, a readout unit B, a readout unit C, and a readout unit D, after binary encoding the readout units, it may be determined that the binary number of the readout unit a is 001, the binary number of the readout unit B is 010, the binary number of the readout unit C is 011, and the binary number of the readout unit D is 100. Since N has a value of 3, 3 electronic channels, i.e., channel 1, channel 2, and channel 3, are required. In the mapping relationship between the preset readout unit and the channel, the readout unit a with the binary number of 001 may be correspondingly connected to the channel 3, the readout unit B with the binary number of 010 may be correspondingly connected to the channel 2, the readout unit C with the binary number of 011 may be correspondingly connected to both the channel 2 and the channel 3, and the readout unit D with the binary number of 100 may be correspondingly connected to the channel 1.
It may be understood that in the embodiment of the present application, after the detection device acquires the trigger signal by executing the data acquisition process, the corresponding data channel containing the valid signal, that is, the trigger channel, may be determined first, then, based on the mapping relationship between the preset readout unit and the channel, the trigger unit corresponding to the trigger channel is obtained by decoding, and the physical position of the trigger signal corresponding to the trigger unit is determined by using the mapping relationship between the preset readout unit and the position.
Therefore, according to the positioning method provided by the application, the mapping relation between the preset reading units and the channels is established on the basis of the binary coding strategy in advance, so that one path of electronic channels can be connected to one or more reading units with a certain bit value of 1 in the binary number, and the trigger signals can be transmitted to all the correspondingly connected electronic channels after the one or more reading units are triggered. For example, assuming that the read plane corresponds to 16 read units, if a read unit with a binary number of 00100 is triggered, the corresponding third electronic channel contains a trigger signal, and no other channel has a signal exceeding the preset intensity threshold at this time, i.e. when the trigger signal is detected, the mapping relationship between the preset read unit and the channel may be used to encode and reversely push out the triggered read unit according to whether the electronic channel has a signal, and then the physical position of the triggered read unit may be further determined according to the mapping relationship between the preset read unit and the position.
In an exemplary embodiment of the present application, based on the above-mentioned fig. 12, fig. 13 is a schematic diagram for implementing a positioning method, and as shown in fig. 13, when a trigger signal is detected through a channel 2 and a channel 3, it may be determined that the readout unit C is triggered at this time based on a mapping relationship between a preset readout unit and the channel.
It can be understood that in the embodiment of the present application, if only one readout unit in the entire readout plane is triggered in one trigger event, the positioning method based on the signal coding readout mode provided by the present application only needs log 2 n paths of electronic channels to complete the positioning processing of a triggered area in n small areas on the plane, so that the electronic channels required for positioning the microstructure gas detector are greatly saved.
The embodiment of the application provides a positioning method, which comprises the steps of determining a trigger channel corresponding to a trigger signal after the trigger signal is detected; determining a triggering unit corresponding to the triggering channel based on a mapping relation between a preset reading unit and the channel; wherein the trigger unit is at least one of all the read-out units in the read-out plane; the mapping relation between the preset reading unit and the channel is established based on a binary coding strategy; and determining a trigger position corresponding to the trigger signal according to the mapping relation between the preset reading unit and the position and the trigger unit. Therefore, in the embodiment of the application, the detection equipment can complete the construction of the mapping relation between the preset reading unit and the channel in advance based on the binary coding strategy, so that after the trigger signal is detected, the corresponding trigger position can be accurately positioned by using a small number of electronic channels through the mapping relation between the preset reading unit and the channel, the number of the read electronic channels can be reduced on the basis of ensuring the position resolution capability of the detector, and the performance of the detector is improved.
