Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The present embodiment provides an automatic detector gain configuration method, which is applied in a data processing unit of a radiation type inspection system, and is used for automatically configuring gain parameters of a detector in the radiation type inspection system, as shown in fig. 2, including the following steps:
s101: acquiring a gain parameter of the detector; as shown in fig. 1, the data processing unit 3 is in communication connection with the detector 2, and is capable of acquiring detection data of each pixel in the detector 2 and acquiring a gain parameter of each pixel. The gain parameter of the detector in this step may be a list or a matrix including the gain parameter of each pixel.
S102: judging whether the gain parameter is in a gain configuration range of the detector, and the difference value between the gain parameter and a user gain configuration parameter is in an allowable range, if so, determining that the gain configuration of the detector has no problem and ending the gain verification, and if not, executing a step S103; accordingly, the user gain configuration parameters of the detector are a list or a matrix including the user gain configuration parameters of each pixel of the detector. And when comparing, comparing the actual gain parameter and the user gain configuration parameter of the same pixel point. The user gain configuration parameters may be pre-stored in the data processing unit 3, and for each pixel, the gain parameter must be within an allowable gain configuration range, and the gain configuration range, whether the gain is discrete or continuous, are stored in the data processing unit 3. The user gain configuration parameters may be the gain configuration parameters correctly set last time. When the detector works for the first time, the gain parameter of each pixel point can adopt a default gain parameter, and the default gain parameter can be any value in the configuration range of the gain parameter of the pixel point. After the detector starts to work, whether the input user gain configuration parameters exist or not can be detected in real time, and once the input user gain configuration parameters are detected, the user gain configuration parameters can be endowed to the detector.
And S103, configuring the gain parameter of the detector according to the difference value, and then returning to S101.
In the above scheme, after the data processing unit 3 is started, the detector gain check is first started, and when the check result is not qualified, the gain parameter of the detector is reconfigured, or before step S101, the method further includes the following steps: and acquiring a user gain configuration parameter, and configuring the gain parameter of the detector according to the user gain configuration parameter. As mentioned above, the user gain configuration parameter may be the gain configuration parameter correctly configured last time, or may be the gain configuration parameter input by the user after startup.
Ideally, the acquired gain parameter of the detector should be the same as the user gain configuration parameter, but in practical application, the parameters may be inconsistent due to factors such as external environment interference, and at this time, the actual gain parameter of the detector output signal may not be the same as the expected gain parameter or the difference value is not within the allowable range. By the scheme, the gain parameters of the detector are reconfigured under the condition until the difference value between the actually detected gain parameters of the detector and the user gain configuration parameters is within the allowable range. When reconfiguration is performed, reconfiguration may be performed according to a difference between a gain parameter of the detector and a user gain configuration parameter, for example, if the gain parameter of the detector is smaller than the user gain configuration parameter, the gain configuration parameter of the current detector needs to be amplified when reconfiguration is performed, or the user gain configuration parameter needs to be used for reconfiguration. By the aid of the scheme, the gain of the detector can be automatically configured in real time in the working process of the detector without manual adjustment of a user, so that the gain parameter of the detector can meet the limitation of the gain configuration range of the detector and the requirement of the user.

In this embodiment, an automatic detector gain configuration method is provided, which is applied to a data processing unit of a radiation type inspection system, and is used for automatically configuring gain parameters of a detector in the radiation type inspection system, as shown in fig. 3, and includes the following steps:
s201: gain parameters of the detector are obtained.
S202: judging whether the gain parameter is in a gain configuration range of the detector, and the difference value between the gain parameter and a user gain configuration parameter is in an allowable range, if so, executing a step S203, otherwise, executing a step S205;
s203: acquiring an air value of the detector, wherein the air value is measured according to the following modes: under the condition that no shielding object exists between the detector to be detected and the radiation source (the shielding object generally refers to other objects except for necessary fixed sealing materials between the radiation source and the detector, such as an object to be inspected), the detector to be detected collects the radiation beam emitted by the radiation source, and detection data obtained by converting the collected radiation beam is used as the air value. Specifically, the method comprises the following steps: air sampling begins → air data is acquired after radiation source radiation dose is stabilized → air sampling ends, and then step S204 is performed.
S204: comparing the ratio of the air value to the upper limit of the air value (i.e. the upper limit of the reading of the detector) with a predetermined ratio range, if the ratio of the air value to the upper limit of the air value is not within the predetermined ratio range, executing step S206, and if the ratio of the air value to the upper limit of the air value is within the predetermined ratio range, ending; in this step, the predetermined proportion range may be selected from 50% to 95%, or different predetermined proportion ranges may be set for the detectors at different positions according to empirical values.
S205: configuring a gain parameter of the detector according to the difference value, and then returning to S201; for example, if the gain parameter of the detector is smaller than the user gain configuration parameter, the gain configuration parameter of the current detector needs to be amplified during reconfiguration, or the user gain configuration parameter needs to be reconfigured.
S206: returning to S201 after the gain parameters of the detector are reconfigured according to the difference between the ratio and the preset ratio range; for example, if the ratio is smaller than the lower limit of the predetermined ratio range, the gain configuration parameter of the current detector needs to be amplified.
The embodiment adds the saturation check detection function on the basis of the embodiment 1, and can automatically reconfigure the gain parameter of the detector when the detector is saturated, so that the gain parameter of the detector can adapt to the requirements of different detection environments, and is more suitable for the requirements of multi-purpose and multi-mode inspection.
Example 3
In the scheme of embodiment 1 or embodiment 2, when the gain parameter of the detector is abnormal, the gain parameter of the detector can be automatically reconfigured until the gain parameter of the detector meets the judgment condition. However, in order to eliminate the problem of device failure of the detector itself and improve the inspection efficiency, the gain parameter of the detector cannot be reconfigured endlessly, so the scheme provided in this embodiment further includes the following steps: and if the times of reconfiguring the gain parameters of the detector reach the set times, sending prompt information of failure of gain configuration of the detector.
In a specific implementation, a parameter may be set for characterizing the number of times the detector is reconfigured, the initial value of the parameter being zero, and once the gain parameter of the detector is reconfigured once, the parameter is increased by one. The set times can be set to 10,15 and the like, and once the number of times of reconfiguring the detector reaches the set times, the reconfiguration is abandoned, and the alarm information is directly sent out, so that the influence on the inspection efficiency caused by repeated reconfiguration in the case of detector failure and the like is avoided.

Accordingly, the user gain configuration parameters of the detector are a list or a matrix including the user gain configuration parameters of each pixel of the detector. And when comparing, comparing the actual gain parameter and the user gain configuration parameter of the same pixel point. The user gain configuration parameters may be pre-stored in the data processing unit 2, and for each pixel, the gain parameter must be within an allowable gain configuration range, and the gain configuration range, whether the gain is discrete or continuous, are stored in the data processing unit 2. The user gain configuration parameters may be the gain configuration parameters correctly set last time. When the detector works for the first time, the gain parameter of each pixel point can adopt a default gain parameter, and the default gain parameter can be any value of the pixel point within the configuration range of the gain parameter of the detector. After the detector starts to work, whether the input user gain configuration parameters exist or not can be detected in real time, and once the input user gain configuration parameters are detected, the user gain configuration parameters can be endowed to the detector.
In the above scheme, after the data processing unit 3 is started, the detection gain check is first started, and when the check result is not qualified, the gain parameter of the detector is configured again, or the gain parameter of the detector is set first, that is, the apparatus further includes an initialization module 303, configured to obtain the user gain configuration parameter, and configure the gain parameter of the detector according to the user gain configuration parameter. As mentioned above, the user gain configuration parameter may be the gain configuration parameter correctly set last time, or may be the gain configuration parameter input by the user after startup.
Ideally, the acquired gain parameter of the detector should be the same as the user gain configuration parameter, but in practical application, the parameters may be inconsistent due to factors such as external environment interference, and at this time, the actual gain parameter of the detector output signal may not be the same as the expected gain parameter or the difference value is not within the allowable range. By the scheme, the gain parameters of the detector are reconfigured under the condition until the difference value between the actually detected gain parameters of the detector and the user gain configuration parameters is within the allowable range. When reconfiguration is performed, reconfiguration may be performed according to a difference between a gain parameter of the detector and a user gain configuration parameter, for example, if the gain parameter of the detector is smaller than the user gain configuration parameter, the gain configuration parameter of the current detector needs to be amplified when reconfiguration is performed, or the user gain configuration parameter needs to be used for reconfiguration. By the aid of the scheme, the gain of the detector can be automatically configured in real time in the working process of the detector without manual adjustment of a user, so that the gain parameter of the detector can meet the limitation of the gain configuration range of the detector and the requirement of the user.
Further, the above apparatus further comprises: an air value obtaining module 304, configured to obtain an air value of the detector, where the air value is measured according to the following manner: under the condition that no shielding object exists between the detector to be detected and the radiation source (the shielding object generally refers to other objects except for necessary fixed sealing materials between the radiation source and the detector, such as an object to be inspected), the detector to be detected collects the radiation beam emitted by the radiation source, and detection data obtained by converting the collected radiation beam is used as the air value. Specifically, the method comprises the following steps: air sampling begins → air data is acquired after radiation source radiation dose is stabilized → air sampling ends.
The gain configuration module 302 is configured to reconfigure the gain parameter of the detector according to a difference between the ratio and the predetermined ratio range when the ratio of the air value to the upper limit value of the air value is not within the predetermined ratio range. The predetermined proportion range can be selected from 50% -95%, or different predetermined proportion ranges can be set for detectors at different positions according to empirical values. For example, if the gain parameter of the detector is smaller than the user gain configuration parameter, the gain configuration parameter of the current detector needs to be amplified during reconfiguration.
The scheme is added with the function of saturation check detection, and when the detector is saturated, the gain parameter of the detector can be automatically reconfigured, so that the gain parameter of the detector meets the requirements of different detection environments, and the method is more suitable for the requirements of multi-purpose and multi-mode inspection.
In the above scheme, when the gain parameter of the detector is abnormal, the gain parameter of the detector can be automatically reconfigured until the gain parameter of the detector meets the judgment condition. However, in order to eliminate the problem of device failure of the detector and improve the inspection efficiency, the gain parameter of the detector cannot be reconfigured endlessly, and to solve the problem, the apparatus may further include a prompt module 305 for sending a prompt message indicating that the gain configuration of the detector fails when the number of times of reconfiguring the gain parameter of the detector reaches a set number of times. In a specific implementation, a parameter may be set for characterizing the number of times the detector is reconfigured, the initial value of the parameter being zero, and once the gain parameter of the detector is reconfigured once, the parameter is increased by one. The set times can be set to 10,15 and the like, and once the number of times of reconfiguring the detector reaches the set times, the reconfiguration is abandoned, and the alarm information is directly sent out, so that the influence on the inspection efficiency caused by repeated reconfiguration in the case of detector failure and the like is avoided.
