Abstract
Description
Technical Field
[0001] This disclosure relates to the field of data monitoring, and more particularly to a radiation dose detection system and a method for planning safe paths in radiation areas. Background Technology
[0002] like Figure 1 As shown, traditional personal dosimeters measure the dose rate and dose received by personnel carrying the device in potential radiation areas in real time. After the personnel carrying the personal dosimeters return to a safe area, the radiation monitoring terminal will summarize the dose rate and dose information recorded by the personal dosimeters, record the dose received by the personnel during a single trip, and calculate the cumulative dose value of the personnel over several trips. The corresponding test results will be uploaded, and the terminal will determine whether an alarm needs to be triggered based on the cumulative dose or dose rate. Alarm methods include text alarms, audible and visual alarms, etc.
[0003] Traditional personal dosimeters can only detect and accumulate doses received by personnel and equipment at fixed points or along travel paths within potential radiation areas. They display dose rate and cumulative dose detection results on an LCD screen and provide text, audible, and visual alarms for exceeding dose limits. Their functionality is limited, offering limited dose protection for individuals and equipment. Furthermore, traditional personal dosimeters cannot constitute a "detection system" and lack the capability to "map dose contour lines in potential radiation areas, delineate static hazard zones, predict dynamic hazard changes, and provide active protection—providing information on safe escape points, identifying, deciding on, and alerting personnel to avoid dose-exceeding hazards, and recommending the optimal path from the starting point to the destination."

[0124] The present disclosure will be further described below by way of examples, but the present disclosure is not limited to the described examples.
[0125] The prefix words such as "first", "second" in the embodiments of the present disclosure are merely used to distinguish different description objects, and have no limiting effect on the position, order, priority, number or content of the described objects. The use of ordinal words such as ordinal words in the embodiments of the present disclosure does not constitute a limitation on the described objects, and the description of the described objects should be referred to the description of the context in the claims or embodiments, and should not constitute an unnecessary limitation because of the use of such prefix words. In addition, in the description of the embodiments, unless otherwise specified, the meaning of "plurality" is two or more.
[0126] The conventional personal dosimeter has the following technical defects:
[0127] The traditional personal dosimeter does not record the path information of the personnel who have entered the "potential radiation area" last time. If the personnel who have entered the "potential radiation area" last time receive an excessive dose during the journey, the dangerous journey information of this time cannot be fed back to the personnel who are about to enter the "potential radiation area" next time, and no warning information of the "potential radiation area" and the path can be provided. If the personnel who need to enter the dangerous area next time still enter according to the last travel route, they may continue to receive an excessive dose.
[0128] After the personnel wearing the traditional personal dosimeter enter the "potential radiation area" dangerous area, if the dose of the dosimeter exceeds the standard, the personnel in the dose-exceeding-dangerous area cannot obtain the location information of the safe escape point, the best path information for leaving the dose-exceeding-dangerous area and returning to the safe area, the dose contour static topology, the clear dose contour distribution information, the dynamic change trend information of the dose contour of the dangerous area, and the information for autonomous judgment and evacuation decision.
[0129] After the personnel wearing the traditional personal dosimeter, the same batch of personnel, and the scattered personnel enter the "potential dangerous area", the traditional personal dosimeter cannot push the dose-exceeding information of the personnel in the "dangerous area" to the personnel in the "safe area" in real time and quickly, so as to avoid the personnel in the "safe area" at the same time from re-entering the "dose-exceeding area", and cannot provide timely and effective information for the subsequent rescue of the personnel in the "dangerous area" and the immediate evacuation of the personnel in the "safe area".
[0130] The traditional personal dosimeter and the radiation monitoring terminal transmit information in one direction, and only the personal dosimeter can transmit information to the "radiation monitoring terminal". The "radiation monitoring terminal" cannot transmit the previous "excessive irradiation dose" and other dangerous information to the personal dosimeter, and cannot realize the iteration and transmission of "useful information".
[0131] The traditional personal dosimeter and the radiation monitoring terminal cannot form an intelligent system and cannot be networked. They do not have the function of three-dimensional dose measurement networking, analysis, and topology.
[0132] Therefore, the planning method of the safe path in the radiation area provided by the present disclosure realizes the static and dynamic analysis, zoning prediction of the potential radiation dangerous area, and provides the optimal travel route planning for the safe escape point of the personnel who enter next time.
[0133] The implementation principle of the planning method of the safe path in the radiation area in the present disclosure will be described below:
[0134] Embodiment 1
[0135] As Figure 2As shown, the embodiment provides a method for planning a safe path in a radiation area, and the method includes the following steps:
[0136] S11: Obtain a plurality of sets of radiation dose information corresponding to different acquisition points in the radiation area;
[0137] S12: Establish a radiation dose map corresponding to the radiation area based on the plurality of sets of radiation dose information;
[0138] S13: Obtain safe path information in the radiation area based on the radiation dose map.
[0139] In the embodiment, the radiation dose information corresponding to different locations in the radiation area is obtained based on a plurality of radiation detection devices; the radiation dose information includes actual position information and radiation value information at the corresponding position; and the different radiation detection devices communicate with each other, wherein the radiation detection device is a personal dosimeter.
[0140] The data collected by the personal dosimeter includes but is not limited to the current dose rate (unit: uSv / h), the current dose value (uSv), the dose cumulative value (uSv), and the dose alarm value (mSv).
[0141] Through the time information communication between the plurality of personal dosimeters, real-time transmission of dangerous information can be realized to ensure the safety of the user.
[0142] In an implementation, the user can carry the personal dosimeter to obtain the radiation dose information at different positions in the radiation area, or an unmanned device such as a drone can be used to detect the radiation dose information at different positions.
[0143] By carrying the personal dosimeter on the drone, air space dose rate detection and cumulative dose calculation can be realized, and a three-dimensional "space point dose, dose rate real-time monitoring" is formed in the "radiation monitoring terminal". In the case of ensuring the safety of the user, the accuracy of establishing the radiation dose map is further improved.
[0144] As shown in Figure 3 Step S12 includes the following steps:
[0145] S121: Obtain a target position of a target radioactive source in the radiation area;
[0146] S122: Obtain a radiation dose map based on the target position and the plurality of sets of radiation dose information.
[0147] In the method for planning a safe path in a radiation area provided by the present disclosure, a radiation dose map at different positions in the radiation area is constructed, and based on the radiation dose map, static and dynamic analysis of potential radiation danger areas, zoning prediction, and optimal travel route planning for safe escape points of subsequent entering personnel are provided.
[0148] In one embodiment, as shown in Figure 4 S121 comprises:
[0149] S12111: obtaining the safety point position information outside the radiation area;
[0150] S12112: obtaining the actual position information of any two different collection points and the radiation value information at the corresponding positions;
[0151] S12113: determining the suspected radiation position of the target radiation source in the radiation area based on the safety point position information, the actual position information, and the radiation value information at the corresponding positions;
[0152] S12114: determining the target position based on a plurality of suspected radiation positions;
[0153] In one embodiment, as shown in Figure 5 S12113 comprises:
[0154] Based on the radiation dose information, an initial radiation area corresponding to the two different collection points is determined; wherein the different initial radiation areas intersect and have a first intersection point A and a second intersection point B, and at this time the safety point information is M in the figure;
[0155] Based on the safety point position information M, the first intersection point A, and the second intersection point B, a first distance and a second distance are respectively obtained; wherein the first distance is the distance from the first intersection point A to the safety point position information M, and the second distance is the distance from the second intersection point B to the safety point position information M;
[0156] In response to the first distance being less than the second distance, the second intersection point is the suspected radiation position; in response to the first distance being greater than the second distance, the first intersection point is the suspected radiation position.
[0157] As shown in Figure 5 The distance from A to M is less than the distance from B to M, and at this time B is the suspected radiation position.
[0158] In another embodiment, as shown in Figure 6 S121 further comprises:
[0159] S12121: obtaining the initial placement position information of the dangerous source within the radiation area;
[0160] S12122: obtaining the actual position information of any two different collection points and the radiation value information at the corresponding positions;
[0161] S12123: determining the suspected radiation position of the target radiation source in the radiation area based on the initial placement position information of the dangerous source, the actual position information, and the radiation value information at the corresponding positions;
[0162] S12124: determining the target position based on the plurality of suspected radiation positions.
[0163] As shown in Figure 7 S12123 includes:
[0164] The step of determining the suspected radiation position of the target radiation source in the radiation region based on the initial placement information of the dangerous source and the radiation dose information includes:
[0165] Based on the radiation dose information, the initial radiation regions corresponding to the two different acquisition points are determined; wherein the different initial radiation regions intersect and have a third intersection point C and a fourth intersection point D; at this time the dangerous source is N in the figure;
[0166] Based on the initial placement information N of the dangerous source, the third intersection point C and the fourth intersection point D, the third distance and the fourth distance are obtained respectively; wherein the third distance is the distance from the third intersection point C to the initial placement information N of the dangerous source, and the fourth distance is the distance from the fourth intersection point D to the initial placement information N of the dangerous source;
[0167] In response to the third distance being less than the fourth distance, the third intersection point is the suspected radiation position;
[0168] In response to the third distance being greater than the fourth distance, the fourth intersection point is the suspected radiation position.
[0169] As shown in Figure 7 The distance from D to N is less than the distance from C to D, so D is the suspected radiation position at this time.
[0170] Wherein the initial radiation region corresponding to the two different acquisition points is circular, and the radius of the circle is inversely proportional to the square of the value corresponding to the radiation dose information collected at the corresponding acquisition point.
[0171] In this embodiment, the step of determining the target position based on the plurality of suspected radiation positions includes:
[0172] Obtain the number of times of occurrence of a plurality of different suspected radiation positions;
[0173] In response to the number of times information being the maximum, the corresponding suspected radiation position is the target position of the target radiation source in the radiation region.
[0174] In the method for planning a safe path in a radiation region provided by the present disclosure, a radiation dose map at different positions in the radiation region is constructed, and based on the radiation dose map, static and dynamic analysis of potential radiation hazard regions, zoning prediction, and optimal travel route planning for safe escape points of subsequent entering personnel are provided.
[0175] As shown in Figure 8 andFigure 9 As shown, step S122 includes:
[0176] S1221: Obtain the radiation distance from different acquisition points in the radiation region to the target position;
[0177] S1222: Obtain the radiation dose information corresponding to different acquisition points, and draw the radiation distance corresponding to the same radiation dose information as the radiation dose contour to obtain the radiation dose map.
[0178] Wherein, the radiation distance is inversely proportional to the square of the corresponding radiation dose information collected at the acquisition point.
[0179] In a preferred radiation scenario, there is only one radiation source, and the scene is empty without any obstruction, at this time, the radiation dose map is taken as the center of the radiation source, and the radiation data information is collected at different positions, such as the radiation data collected at 1m from the center is a, then the radiation data at 1m from the center is a; the radiation data collected at 2m from the center is b, then the radiation data at 2m from the center is b.
[0180] In the actual scene, there is a radiation source, and there are different obstructions in the scene, that is, the same radiation data will be obtained at different positions, such as the data collected at 1m from the center is a, and the data collected at 2m from the center is also a, at this time, taking the radiation source as the center, first draw a circle with 1m and 2m respectively corresponding to the data, obtain the specific position at 2m, connect the position at 2m with the center to form an intersection at the circle at 1m, and based on the intersection and the position at 2m, stretch the circle corresponding to 1m outward to obtain the contour map of the radiation data a, and the corresponding radiation dose map is realized through specific computer software.
[0181] In an embodiment, step S13 includes:
[0182] Obtain the current position information, and obtain the radiation dose gradient information in different directions at the current position based on the radiation dose map;
[0183] Obtain the minimum value information of the radiation dose gradient information;
[0184] Obtain the preferred evacuation path in the radiation region based on the minimum value information;
[0185] Obtain the evacuation time and cumulative radiation information in the radiation region based on the preferred evacuation path;
[0186] In response to the cumulative radiation information being less than a preset standard value, the preferred evacuation path is the safe path information;
[0187] In response to the accumulated radiation information being greater than or equal to a preset standard value, minimum radiation dose rate information at a distance within a first threshold of the current position information is acquired, and safe path information is determined based on the minimum radiation dose rate information.
[0188] The preset standard value in the embodiment is a personal safety irradiation dose value; the radiation dose rate information in the embodiment is directly measured based on a personal dosimeter; and the accumulated radiation information is a product of the current evacuation time and the radiation dose rate information at the current position.
[0189] After the step of acquiring safe path information in the radiation area based on the radiation dose map, the planning method further comprises:
[0190] Acquiring actual environment information in the radiation area;
