[0048] Different embodiments or examples are provided below to realize different structures of the present application. In order to simplify the present application, the parts and settings of specific examples are described below. Of course, they are only used as examples, and the purpose is not to limit the present application. The present application can repeat the figure numerals in different examples, and this repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings described in itself.

[0049] Some preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the following description is for illustrative purposes and is not intended to limit the scope of protection of the present application.

[0050] Figure 1 1 is an exemplary module diagram of a radiation probe according to some embodiments of the present application. The radiation probe 100 is externally mounted on a mobile terminal and is in communication connection with the mobile terminal. The radiation probe is configured to obtain a radiation count value of a target object or an area around the target object, and send the obtained radiation count value to the mobile terminal.

[0051] In some embodiments, the mobile terminal may include mobile phones, tablet computers, laptop computers, robots and other devices, but is not limited thereto.

[0052] In some embodiments, the target object may be a living organism, including but not limited to a human, such as a police dog. The target object may also be a specific intelligent mobile device, such as an intelligent mobile robot, a sweeping robot, a patrol drone, a submarine, etc. Specifically, taking the target object as a human as an example, obtaining the radiation count value of the target object, that is, obtaining the radiation count value of the individual, obtaining the radiation count value of the area around the target object, may include obtaining the radiation count value of the environment around the person, obtaining the radiation count value related to the distance representation between the individual and the radiation source (which can be used to find the radiation source, referred to as source seeking).

[0053] In some specific embodiments, the radiation count value is a radiation count value obtained based on a comparison threshold, as described below.

[0054] like Figure 1 As shown, the radiation probe 100 may include: a detection module 110, configured to obtain a scintillation pulse signal based on a target object or an area surrounding the target object; a counting module 120, configured to obtain a radiation count value of the target object or an area surrounding the target object based on the scintillation pulse signal and a comparison threshold.

[0055] In some embodiments, the scintillation pulse signal should be understood as any pulse signal that can be sampled, and its essence is a physical quantity that undergoes a sudden change in a short period of time and then quickly returns to its initial value.

[0056] In some specific examples, the scintillation pulse signal is usually characterized by having a rising edge and a falling edge, and the rising edge and the falling edge can be represented by a function model. In some embodiments, the scintillation pulse signal corresponding to the gamma photon is usually characterized by having a relatively fast rising edge and a relatively slow falling edge, the rising edge can be represented by a straight line function, and the falling edge can be represented by an exponential function.

[0057] In some embodiments, the flash pulse signal may be expressed in the form of an electrical pulse signal, an acoustic pulse signal, a thermal pulse signal, or a pressure wave signal, etc. For example, when the pulse signal is an electrical pulse signal, its corresponding characteristics may be the voltage and current of the electrical pulse signal; when the pulse signal is an acoustic pulse signal, its corresponding characteristics may be the sound intensity of the acoustic pulse signal, and so on, which will not be repeated here.

[0058] Those skilled in the art should understand that the flickering pulse signal in the present application can be expanded to a continuous signal. Usually, the continuous signal only needs to be regarded as a flickering pulse signal arranged in a certain period. The flickering pulse signal in the present application is not a limitation on the sampled signal.

[0059] In some embodiments, the scintillation pulse signal is acquired based on the detection module 110. The detection module 110 includes a scintillation crystal and a photoelectric converter that are coupled to each other. The scintillation crystal is configured to convert high-energy rays acquired based on receiving the target object or the area around the target object into visible light. For example, the scintillation crystal can be used to convert high-energy rays such as detected gamma photons into visible light signals, and the photoelectric converter is used to convert the visible light signal into a scintillation pulse electrical signal, which is output in the form of a digital signal through a counting module connected to the photoelectric conversion device.

[0060] In some specific examples, the scintillation crystal may be a scintillation crystal array, and the photoelectric converter includes but is not limited to a silicon photomultiplier (SiPM) or a photomultiplier tube (PMT).

[0061] In some embodiments, the counting module is further configured to:

[0062] Obtain corresponding comparison thresholds based on different working modes;

[0063] comparing the scintillation pulse signal with a comparison threshold;

[0064] The scintillation pulses received by the detection module are counted according to the comparison result to obtain a radiation count value.

[0065] Specifically, the radiation count value is based on comparing the amplitude of the scintillation pulse signal output by the detection module in response to the received high-energy rays with the obtained comparison threshold. The radiation count value obtained according to the comparison result can usually be represented as CPS (abbreviation of count per second).

[0066] In some specific embodiments, different working modes may include a source seeking mode, a target object radiation detection mode, or an environmental radiation detection mode.

[0067] In some specific embodiments, the counting module includes:

[0068] A power supply, configured to supply power to the radiation probe;

[0069] a comparator configured to compare the scintillation pulse signal with a comparison threshold;

[0070] a counter configured to count the flicker pulses according to the comparison result;

[0071] a processor configured to configure the radiation probe according to an instruction of the mobile terminal, obtain a radiation count value, and send the obtained radiation count value to the mobile terminal;

[0072] Among them, the processor is communicatively connected with the comparator, the counter, the power supply, and the mobile terminal.

[0073] In some embodiments, the power supply of the counting module supplies power to the comparator, the photoelectric converter, the counter, and the processor of the detection module. The power supply can be powered by a power module of the mobile terminal, but is not limited thereto.

[0074] In some specific examples, the comparator may include a voltage comparator, but is not limited thereto. The comparison threshold of the comparator may be set by a resistor network. Specifically, the power provided by the power module of the mobile terminal may be input into the resistor network of the comparator of the counting module, and the resistor voltage division on different network nodes may be input into different comparators as the comparison threshold of the comparator. The specific operation may refer to the prior art and will not be described in detail here.

[0075] In some specific examples, after the comparator receives the scintillation pulse signal output by the detection module, the amplitude of the scintillation pulse signal can be compared with the comparison threshold, and the corresponding comparison result can be output. Specifically, when the amplitude of the scintillation pulse signal is greater than or equal to the comparison threshold, the comparator can generate an edge jump (for example, a rising edge jump) and can output a valid level signal, for example, 1; when the amplitude of the scintillation pulse signal is less than the comparison threshold, the comparator maintains the current state and can output an invalid level signal, for example, 0. The valid level signal here can be a high level or a low level, and correspondingly, the invalid level signal can be a low level or a high level.

[0076] In some embodiments, the counter can be a multi-bit synchronous counter or a multi-bit asynchronous counter, or other types of counters. After the counter receives the level signal output by the comparator, it counts the flicker pulses received by the detection module according to the received level signal in a preset counting method. For example, each time a valid level signal is received, it adds 1 to the current count; each time an invalid level signal is received, it maintains the current count unchanged. In addition, the counter can store the recorded counting data while counting, and can also periodically output the recorded radiation count value according to the radiation count value statistical frequency set by the mobile terminal.

[0077] In some embodiments, the processor is further configured to obtain first-category parameter information sent by the mobile terminal, send the first-category parameter information to the comparator and the power supply, and send the obtained radiation count value to the mobile terminal; the first-category parameter information includes the operating voltage value, comparison threshold, and radiation count value statistical frequency of the photoelectric converter of the radiation probe.

[0078] In some specific examples, taking a mobile phone as an example, after the processor of the radiation probe obtains the first type of parameter information sent by the mobile phone, it sets the working voltage value of the photoelectric converter, sets the comparison threshold value in the corresponding specific working mode, sets the radiation count value statistical frequency, etc. based on the corresponding parameter information, so as to facilitate the radiation probe to work in the source search mode, the target object radiation detection mode or the environmental radiation detection mode, and accordingly obtains the location information of the radiation source, the radiation dose of the target object, the radiation dose of the environment around the target object, and other radiation count values ​​according to the obtained count value, mobile phone positioning information, etc. The radiation count value obtained by the radiation probe is sent to the mobile phone for processing.

[0079] The radiation probe provided by the present application is externally mounted on the mobile terminal and is connected to the mobile terminal in communication, so that the radiation probe itself no longer needs to be provided with traditional interactive devices such as a display screen, and the volume is greatly reduced, and the portability is high. At the same time, since the radiation probe only includes a basic detection unit, other power supplies, display screens, processors or alarm units are implemented with the original components of the mobile device, which greatly reduces the cost of the radiation detection equipment and is conducive to its large-scale market application.

[0080] Figure 2 is an exemplary module diagram of a mobile terminal according to some embodiments of the present application, such as Figure 2 As shown, the mobile terminal 200 includes:

[0081] The radiation probe interface 210 is configured to communicate with an external radiation probe to obtain radiation count values; the processing unit 220 is configured to receive and process the radiation count values.

[0084] a power module configured to supply power to the radiation probe;

[0085] A communication module configured to send parameter information to the radiation probe and receive radiation count values ​​sent by the radiation probe;

[0091] In some specific examples, the alarm module may alarm in the form of one or more combinations of sound, light or vibration, but is not limited thereto.

[0092] In some embodiments, the first type of parameter information includes the operating voltage value, comparison threshold, and statistical frequency of the radiation count value of the photoelectric converter of the radiation probe; the second type of parameter information includes the coefficients of the function model in the calculation unit.

[0093] In some specific examples, the function model can be:

[0094] y=CPS×k……………………Equation (1)

[0095] Among them, y is the radiation dose value, CPS is the radiation count value output by the radiation probe, and k is the corresponding coefficient under different working modes.

[0096] Specifically, for the CPS obtained by the radiation probe in different working modes, for example, the CPS obtained in the source seeking mode, the target object radiation detection mode or the environmental radiation detection mode, the mobile terminal uses the corresponding coefficient k in the corresponding working mode for calculation to obtain the corresponding radiation dose value y.

[0097] In some embodiments, the meanings or descriptions of the same or similar terms or features in the mobile terminal 200 can refer to the above-mentioned radiation probe 100, that is, the steps and features of the radiation probe 100 can be combined with the mobile terminal 200 in a non-contradictory manner.

[0101] In some specific embodiments, the radiation probe 310 can specifically refer to Figure 1 In the embodiment shown, the mobile terminal 320 can refer to Figure 2 The embodiment shown.

[0103] In some embodiments, the radiation probe is connected to the mobile terminal through a USB interface or a conversion tool. Specifically, the radiation probe is connected to the mobile terminal through a USB interface, making the radiation probe highly portable; the radiation probe is connected to the mobile terminal through a conversion tool (such as a rod-shaped member), etc., and the radiation probe can be placed in an area that is inconvenient for people to reach (such as a corner, etc.) for detection, thereby broadening its application range.

[0104] In some other embodiments, the radiation probe is communicatively connected to the mobile terminal via a flexible line.

[0105] In some specific examples, the radiation probe can be attached to the surface of the mobile terminal through a magnetic element. The specific operation can refer to the prior art and will not be described here. The radiation probe is attached to the surface of the mobile terminal through a magnetic element, etc., which improves the portability of the radiation probe.

[0106] In some embodiments, the meanings or descriptions of the same or similar terms or features in the radiation detection system 300 can refer to the above-mentioned radiation probe 100 and mobile terminal 200, that is, the steps and features of the radiation probe 100 and mobile terminal 200 can be combined into the radiation detection system 300 in a non-contradictory manner.

[0107] The mobile terminal provided in the present application can quickly and conveniently combine the radiation probe to obtain the radiation level of the mobile terminal user or the environment in which the mobile terminal is located through the radiation probe interface and the processing unit, and provide fast and accurate alarm prompts when the radiation level exceeds the standard, which is beneficial to maintaining the personal safety of the mobile terminal user.

[0108] Figure 4 is an exemplary flow chart of a radiation detection method according to some embodiments of the present application.

[0109] Continue to see Figure 4 , the radiation detection method 400 may include the following steps:

[0110] Step S410, obtaining a radiation count value of the target object or the area around the target object through a radiation probe;

[0111] Step S420: sending the radiation count value acquired by the external radiation probe to the mobile terminal.

[0112] In some embodiments, step S410 includes:

[0113] Obtain corresponding comparison thresholds based on different working modes;

[0114] Acquire a scintillation pulse signal;

[0115] comparing the scintillation pulse signal with a comparison threshold;

[0116] A radiation count value is obtained according to the comparison result.

[0117] In some embodiments, before step S410, the radiation detection method further includes: receiving, through a radiation probe, first type parameter information sent by a mobile terminal; and obtaining a radiation count value of the target object or an area surrounding the target object based on the first type parameter information.

[0118] In some embodiments, the meanings or descriptions of the same or similar terms or features in the radiation detection method 400 can refer to the above-mentioned radiation probe 100, mobile terminal 200, and radiation detection system 300, that is, the steps and features of the radiation probe 100, mobile terminal 200, and radiation detection system 300 can be combined into the radiation detection method 400 in a non-contradictory manner.

[0119] Figure 5 is an exemplary flow chart of a radiation detection method according to some embodiments of the present application.

[0120] Continue to see Figure 5 , the radiation detection method 500 may include the following steps:

[0121] Step S510, receiving, through a mobile terminal, a radiation count value of a target object or an area around the target object acquired by an external radiation probe;

[0122] Step S520, processing the received radiation count value through the mobile terminal, when the radiation dose value obtained through the radiation count value exceeds the dose threshold, triggering an alarm.

[0123] In some embodiments, step S510 includes:

[0124] Step S511, obtaining a radiation dose value based on the radiation count value;

[0125] Step S512, comparing the acquired radiation dose value with the set dose threshold, and storing the acquired radiation dose and sending it to the display element; when the radiation dose value exceeds the dose threshold, an alarm is activated.

[0126] In some embodiments, step S512 converts the radiation count value into a radiation dose value by using the function model shown in formula (1). For the specific function model, see Figure 2 Examples are not repeated here.

[0127] In some specific embodiments, the second type of parameter information includes coefficients of the function model shown in equation (1).

[0128] In some embodiments, step S511 includes:

[0130] Radiation dose values ​​are calculated and stored based on the different coefficients.

[0131] In some specific embodiments, the different working modes are a source seeking mode, a target object radiation detection mode, or an environmental radiation detection mode.

[0132] Furthermore, when the specific working mode is the source search mode, the coefficient k of the function model in formula (1) is set to 1. At this time, the radiation dose value is only related to the radiation count value (i.e., CPS), which can easily identify abnormal radiation doses, thereby helping to quickly lock the location of the radiation source. In other embodiments, when the specific working mode is the target object radiation detection mode or the environmental radiation detection mode, the coefficient k of the function model in formula (1) can be set to a suitable value greater than 0 and less than 0.1 to facilitate the detection of radiation doses. In the embodiment of the present application, the corresponding calculation parameters can be set according to different work needs, which expands the application range of the radiation probe and improves its versatility.

[0133] In some embodiments, before step S510, the radiation detection method also includes: sending first-category parameter information to the radiation probe; the radiation count value of the target object or the area around the target object is acquired by the radiation probe based on the first-category parameter information; the first-category parameter information includes the operating voltage value, comparison threshold, and radiation count value statistical frequency of the photoelectric converter of the radiation probe.

[0135] Figure 6 is an exemplary flow chart of a radiation detection method according to some embodiments of the present application.

[0136] Continue to see Figure 6 , the radiation detection method 600 may include the following steps:

[0137] Step S610, obtaining a radiation count value of the target object or the area around the target object through a radiation probe external to the mobile terminal;

[0138] Step S620, receiving and processing the radiation count value sent by the external radiation probe through the mobile terminal.

[0139] In some embodiments, step S610 includes:

[0140] Obtaining a corresponding comparison threshold based on a specific working mode;

[0141] Acquire a scintillation pulse signal;

[0142] comparing the scintillation pulse signal with a comparison threshold;

[0143] A radiation count value is obtained according to the comparison result.

[0144] In some embodiments, step S620 includes:

[0145] Step S621, obtaining a radiation dose value based on the radiation count value;

[0146] Step S622, compare the acquired radiation dose value with the set dose threshold, and store the acquired radiation dose and send it to the display element; when the radiation dose value exceeds the dose threshold, activate an alarm.

[0147] In some embodiments, step S622 converts the radiation count value into a radiation dose value by using the function model shown in formula (1). For the specific function model, see Figure 2 Examples are not repeated here.

[0148] In some specific embodiments, the second type of parameter information includes coefficients of the function model shown in equation (1).

[0153] Specifically, when the specific working mode is the source search mode, the coefficient k of the function model in formula (1) is set to 1.

[0154] In some embodiments, before step S610, the radiation detection method further includes: sending parameter information to the radiation probe via the mobile terminal; and obtaining the radiation count value of the target object or the area around the target object via the radiation probe based on the parameter information.

[0155] In some specific examples, taking a mobile phone as an example, after the processor of the radiation probe obtains the first type of parameter information sent by the mobile phone, it sets the working voltage value of the photoelectric converter, sets the comparison threshold value in the corresponding specific working mode, sets the radiation count value statistical frequency, etc. based on the corresponding parameter information, so as to facilitate the radiation probe to work in the source search mode, the target object radiation detection mode or the environmental radiation detection mode, and obtains the location information of the radiation source, the radiation dose of the target object, the radiation dose of the surrounding environment of the target object and other radiation count values. The radiation count value obtained by the radiation probe is sent to the mobile phone for processing. After the mobile phone receives the radiation count value, i.e., the radiation count value, the coefficient k corresponding to the specific working mode is selected, and the radiation dose value y is calculated using formula (1), and the obtained radiation dose value y is compared with the preset radiation dose threshold, and the obtained radiation dose is stored and sent to the display element (such as the mobile phone radiation dose display applet); when the dose threshold is exceeded, it indicates that the radiation dose is high, and a sound alarm, a vibration alarm, etc. are used.
