Description

Technical Field

[0001] This application relates to the field of nuclear power plant radiation protection technology, and in particular to an indoor wireless positioning electronic dosimeter. Background Technology

[0002] Electronic dosimeters are personal dose alarm devices worn by workers in nuclear power plants and other environments exposed to radiation. Their function is to measure the radiation dose received by the wearer in real time, ensuring that the radiation dose remains within a reasonable level. When the electronic dosimeter measures that the radiation dose received by the wearer exceeds the safe limit, it will sound an alarm to allow the wearer to leave the radiation environment as soon as possible, thus protecting the user. However, within the radiation control area of ​​a nuclear power plant, the amount of radiation received varies depending on the specific location of the worker.

[0003] Current electronic dosimeters can acquire dose information in real time through various wireless communication methods, but this dose information does not include the location information of the personnel in the radiation control room, and cannot provide wearers with more detailed radiation information. Since the radiation control area of ​​a nuclear power plant is basically located inside a heavy concrete building, satellite signals are not available, so GPS or Beidou technology cannot be used to locate the electronic dosimeter.

[0004] Therefore, there is an urgent need for an indoor wireless positioning electronic dosimeter. Summary of the Invention

[0005] In view of this, this application provides an indoor wireless positioning electronic dosimeter device for use in the radiation control area of ​​a nuclear power plant. It can determine the specific location of the wearer in the radiation control area and further accurately measure the radiation dose received by the wearer, thereby further protecting the wearer.

[0007] In some embodiments of this application, a radiation protection method is provided, applied to a processor in a radiation control area, the processor being communicatively connected to an electronic dosimeter. The method includes: acquiring radiation dose information and the current location information of the device based on the device; the radiation dose information including accumulated radiation dose values ​​and / or radiation dose rates; determining whether the radiation dose information exceeds a preset threshold based on the radiation dose information and the location information; and issuing an alarm message when the radiation dose information exceeds the preset threshold.

[0016] To more clearly illustrate the technical solutions of the embodiments in this specification, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this specification. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0017] It should be understood that the terms “system,” “device,” “unit,” and / or “module” used herein are one way to distinguish different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0018] As indicated in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of expressly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0019] Flowcharts are used in this specification to illustrate the operations performed by the system according to embodiments of this specification. It should be understood that the preceding or following operations are not necessarily performed in exact order. Instead, the steps can be processed in reverse order or simultaneously. Furthermore, other operations can be added to these processes, or one or more steps can be removed from them.

[0020] Figure 1 This is an exemplary structural diagram of an electronic dosing device according to some embodiments of this specification. In some embodiments, the electronic dosing device 100 may include a semiconductor detection module 110, an indoor positioning module 120, a data processing module 130, and an alarm module 140, as described below in detail.

[0021] The semiconductor detection module 110 can be used to acquire radiation dose information. This radiation dose information includes the cumulative radiation dose value and / or radiation dose rate.

[0022] In some embodiments, the cumulative radiation dose value can be the radiation dose value generated by the electronic dosimeter over a continuous period of time while it is in the radiation zone. For example, it can be the current cumulative radiation dose value calculated from the moment a worker wearing the electronic dosimeter enters the indoor radiation zone.

[0023] In some embodiments, the radiation dose rate can be the radiation dose value obtained per unit time. For example, the preset unit time is per minute, and the radiation dose rate is the radiation dose value generated per minute.

[0024] In some embodiments, the semiconductor detection module may include a nuclear radiation detector, also known as a nuclear detection element. Understandably, upon receiving bombardment from nuclear radiation particles, the semiconductor detector generates an electron pulse signal, which is then converted into a current pulse signal. By processing the current pulse information, radiation dose information, i.e., the cumulative radiation dose value and / or radiation dose rate, is obtained.

[0025] In some embodiments, the semiconductor detection module may include a built-in calculation unit, which can process the current pulse information according to a corresponding algorithm to obtain radiation dose information.

[0026] The indoor positioning module 120 can be used to receive positioning information sent by the wireless positioning base station and determine the current location information of the electronic dosing device based on the positioning information.

[0027] In some embodiments, the wireless positioning base station may include an ultra-wideband distance measurement (UWB) positioning base station. The indoor positioning module is used to receive positioning signals emitted by the UWB positioning base station and determine the electronic dosing device based on the positioning information.

[0028] Please refer to the following: Figure 2 , Figure 2 This diagram illustrates how an ultra-wideband distance measurement and positioning base station determines the location information of an electronic dosimeter according to some embodiments of this specification. It is understood that multiple UWB positioning base stations are deployed in the radiation-affected workplace. The indoor positioning module in the electronic dosimeter sends repetitive, uninterrupted electromagnetic pulses to these multiple UWB positioning base stations. Each UWB positioning base station uses a highly sensitive short-pulse detector to measure the time difference between the pulses sent by the indoor positioning module and the pulses at different UWB positioning base stations. A UWB positioning calculation server uses triangulation technology and optimization algorithms (wherein the positioning technology and optimization algorithms can be time of arrival algorithms, time difference of arrival algorithms, and angle of arrival algorithms) to calculate the location of the indoor positioning module (i.e., the location of the electronic dosimeter). The UWB positioning calculation server then transmits the location information to the indoor positioning module via a wireless communication base station.

[0029] In some embodiments, the wireless positioning base station may include a Bluetooth positioning base station, and the indoor positioning module is used to receive the positioning signal emitted by the Bluetooth positioning base station and determine the current location information of the electronic dosing device based on the positioning information.

[0030] Please refer to the following: Figure 3 , Figure 3This is an example diagram illustrating the determination of the location information of an electronic dosimeter by Bluetooth positioning base stations according to some embodiments of this specification. It is understood that multiple Bluetooth positioning base stations are deployed in the radiation-affected workplace. These multiple Bluetooth positioning base stations continuously transmit broadcast signals and data packets. The indoor positioning module can sense the broadcast signals emitted by these multiple Bluetooth positioning base stations, and then calculate the Signal Strength Indication (RSSI) under the multiple Bluetooth positioning base stations. It then uses a positioning algorithm built into the calculation unit within the indoor positioning module to calculate the location information of the indoor positioning module, i.e., the location information of the electronic dosimeter.

[0031] The data processing module 130 can be used to process radiation dose information and location information, and determine whether the radiation dose information exceeds a preset threshold based on the radiation dose information and location information; when the preset threshold is exceeded, the alarm module 140 is triggered.

[0032] In some embodiments, the data processing module may be a device with data processing capabilities, such as a central processing unit (CPU).

[0033] In some embodiments, the data processing module can acquire and process radiation dose information and location information from the semiconductor detection module and the indoor positioning module within a preset time interval (e.g., every 0.5 seconds, every second, every 5 seconds, etc.). For example, the preset time interval can be every second, with the data processing module acquiring radiation dose information and location information from the semiconductor detection module and the indoor positioning module every second. In some embodiments, the data processing module acquires the radiation dose information and location information by receiving them from the semiconductor detection module and the indoor positioning module.

[0034] The preset threshold can be the dose value at which the radiation received by workers in the radiation area would cause harm to their bodies.

[0035] In some embodiments, the preset threshold can be determined based on radiation dose information and location information. It is understood that the preset threshold here can include the radiation dose received by the user as they leave the radiation zone, and the preset threshold can be determined based on the user's current location and the location of the non-radiation zone. Furthermore, the preset threshold will be larger when the user's location is far from the non-radiation zone, and smaller when the user's location is close to the non-radiation zone. Therefore, the radiation dose received by the user when they finish their work and walk away from the radiation zone after the alarm is triggered will not cause harm to their health.

[0036] In some embodiments, the data processing module can compare the radiation dose information and location information with a preset threshold for the radiation dose information. When the radiation dose information does not exceed the preset threshold, no alarm information is triggered; when the radiation dose information exceeds the preset threshold, an alarm information is triggered.

[0037] The alarm module 140 can be used to issue an alarm signal when it is triggered.

[0038] In some embodiments, the alarm signal may include sound, light, vibration, text, voice, etc. In some embodiments, the alarm module may include an audible, visual, and vibration alarm, which, when triggered, emits sound, light, and vibration to alert the user that the current radiation dose is close to exceeding the standard and may easily cause harm to the body.

[0039] Figure 4 This is an exemplary structural diagram of another electronic dosing device according to some embodiments of this specification. In some embodiments, the electronic dosing device 400 may further include: a clock module 150, a wireless communication module 160, a power supply module 170, a display module 180, and a wired communication module 190. The following is a detailed description of the above modules.

[0040] The clock module 150 can be used to send time information to the data processing module. Further, the data processing module processes the radiation dose information, location information, and time information in parallel to obtain message information, which includes the organized radiation dose information, location information, and time information. Understandably, the radiation dose values ​​received at different locations within the radiation area can be obtained through the message information, allowing for further research on the radiation area.

[0041] In some embodiments, the data processing module can store the acquired message information in a data register. The data recording rule can be based on a fixed time interval trigger (e.g., every 5 seconds, every 10 seconds, etc.) or on triggering a certain cumulative radiation dose. In some embodiments, the data recording rule can be changed via wired or wireless means.

[0042] The wireless communication module 160 is used to send message information. Understandably, the wireless communication module is used to transmit the message information in the data register via radio signals. In some embodiments, the electronic dosing device can obtain time information through the wireless communication module for calibrating the clock module.

[0043] In some embodiments, the wireless communication module may be a wireless communication technology based on WiFi, 4G, or 5G.

[0044] The power module 170 is used to provide power to the electronic dosing device to control the start and stop of the device, and to control the start and stop of the device; it is also used to send battery power information to the data processing module.

[0045] Display module 180 is used to display at least one of the radiation dose information, battery power information, wireless communication signal strength information, and time information of the device.

[0046] In some embodiments, the display module may be an LCD screen, and the display module may be connected to the data processing module via a ribbon cable. In some embodiments, the display module may also display alarm information, allowing staff to obtain their current hazard status through the display module.

[0047] The wired communication module 190 is used for debugging the electronic dosimeter. In some embodiments, the calibration of the radiation dose alarm preset threshold information can be set through the wired communication module. In some embodiments, message information data can also be downloaded via a wired connection through the wired communication module.

[0048] Figure 5 This is an exemplary flowchart illustrating a radiation protection method according to some embodiments of this specification. The method is applied to a processor in a radiation control area, the processor being coupled with... Figure 1 and / or Figure 4 The electronic dosing device communication connection is described in the document. It is understood that the radiation control area includes a radiation area and a non-radiation area. Workers operate within the non-radiation area and enter the radiation area when necessary. The method (process 500) includes steps 502, 504, and 506, which are described in detail below.

[0049] Step 502: Obtain the radiation dose information of the device and the current location information of the device; the radiation dose information includes the cumulative radiation dose value and / or radiation dose rate. In some embodiments, this step may be performed by the acquisition module 610.

[0050] In some embodiments, the processor obtains the current radiation dose information and location information of the staff located within the radiation area, wherein the radiation dose information includes the radiation dose value and / or radiation dose rate of the current misconduct.

[0051] Furthermore, the processor can acquire radiation dose information and location information of the electronic dosimeter at fixed time intervals (every 1 second, every 5 seconds, etc.).

[0052] Step 504: Based on the radiation dose information and location information, determine whether the radiation dose information exceeds a preset threshold. In some embodiments, this step may be performed by the determination module 620.

[0053] In some embodiments, the processor can determine whether the radiation dose exceeds a preset threshold based on the acquired radiation dose information and location information. This determines whether the electronic dosimeter within the radiation area is currently in an alarm state.

[0054] Step 506: When the radiation dose information exceeds a preset threshold, an alarm message is issued. In some embodiments, this step may be performed by the alarm module 640.

[0055] In some embodiments, an alarm is issued when the determined radiation dose exceeds a preset threshold. This alerts staff in non-radiation areas, and if staff in radiation areas carrying electronic dosimeters do not detect the alarm, alerts can be issued by staff in non-radiation areas, further ensuring the safety of staff in radiation areas.

The system includes, as shown in the diagram... Figure 1 and / or Figure 4 The electronic dosing device described in the document.

[0057] like Figure 6 As shown, the radiation protection system may include: an acquisition module 610, a determination module 620, and an alarm module 630.

[0058] The acquisition module 610 can be used to acquire radiation dose information of the device and the current location information of the device; the radiation dose information includes the cumulative radiation dose value and / or radiation dose rate.

[0059] The determination module 620 can be used to determine whether the radiation dose information exceeds a preset threshold based on the radiation dose information and the location information.

[0060] The alarm module 630 issues an alarm message when the radiation dose information exceeds a preset threshold.
