Description

Technical Field

[0001] This invention belongs to the field of radiation dose monitoring technology, specifically relating to a method and system for data transmission, location tracing, and power consumption management of a personal dosimeter. Background Technology

[0002] Traditional dosimeters lack dose traceability capabilities, making it impossible to synchronize real-time personnel location with real-time dose information. If a dosimeter triggers an over-threshold alarm within the controlled area, radiation protection personnel will use the original dose traceability method, employing a more sensitive dose rate instrument to check the movement path of the worker wearing the dosimeter point by point. This method is inefficient and results in delayed emergency response, as it cannot quickly correlate dose mutations with the location of the radiation source, leading to a delay in leak response.

[0003] Currently, personal dosimeters generally rely on WiFi / 5G to directly transmit data. However, in complex environments such as nuclear power plants (e.g., metal shielding, underground facilities), wireless signal coverage may be incomplete, and the packet loss rate of wireless measurement data transmission can be as high as 30%. Since there is no mechanism for resuming transmission after disconnection at the dosimeter end, if the WiFi / 5G signal is interrupted, the server cannot obtain the complete dose history, affecting the real-time performance and traceability of dose monitoring.

[0004] In addition, most wireless smart dosimeters use a fixed strategy to upload dose data and location information at fixed intervals, which cannot adapt to dose change scenarios, resulting in redundancy or omission of key data. At the same time, the timed upload strategy requires high-frequency communication, which will increase the power consumption of the device. Summary of the Invention

[0005] In order to solve at least one of the above-mentioned technical problems in the prior art, the present invention provides a method and system for data transmission, location tracking and power consumption management of a personal dosimeter.

[0006] This invention employs the following technical solution: a method for data transmission, location tracing, and power consumption management of a personal dosimeter, comprising the following steps: S1: Matching the reader at the entrance of the nuclear power plant control area, activating and loading a preset data upload strategy; the data upload strategy includes a timed upload strategy and a dynamic upload strategy; S2: Obtaining radiation information along the path during activity in the control area and encapsulating it to obtain a radiation data packet; the radiation data packet includes a timestamp, incrementing sequence number, dose rate, cumulative dose, and location tag; S3: Based on the data upload strategy, sending the radiation data packet to the server; the radiation data packet is used to trigger the server to generate a two-level ACK response; S4: Receiving the two-level ACK response and, based on the two-level ACK response and dose... The signal strength of the instrument is used to determine whether the dosimeter is disconnected. If it is determined to be connected, return to step S3; if it is determined to be disconnected, proceed to step S5. S5: Based on the data upload strategy corresponding to the previous radiation data packet, continue to store the new radiation data packet in the local cache of the dosimeter and mark it with an incrementing sequence number until the signal is restored and the latest data-level ACK is received from the server. S6: Compare the sequence number in the latest data-level ACK with the sequence number in the local cache of the dosimeter to filter out the missing radiation data packets. S7: Re-upload the missing radiation data packets to the server in chronological order, clear the uploaded cached data, and return to step S3. S8: After the nuclear power plant control area operation is completed, match the reader at the exit of the nuclear power plant control area and leave the control area.

[0007] Preferably, the timed upload strategy transmits radiation data packets based on a fixed upload period; the dynamic upload strategy dynamically adjusts the upload period based on the dose change rate to transmit radiation data packets; the dose change rate is based on the real-time dose detected by the dosimeter and is obtained through a sliding window algorithm.

[0008] Preferably, the dynamic upload strategy includes a stable mode, an early warning mode, and an emergency mode. When the dose change rate is less than 5%, the corresponding dynamic upload strategy is the stable mode, in which a radiation data packet is uploaded every 60 seconds, consistent with the upload cycle in the timed upload strategy. When the dose change rate is greater than or equal to 5% and less than 20%, the corresponding dynamic upload strategy is the early warning mode, in which a radiation data packet is uploaded every 30 seconds. When the dose change rate is greater than or equal to 20%, the corresponding dynamic upload strategy is the emergency mode, in which a radiation data packet is uploaded every 1 second.

[0009] Preferably, the update frequency of the location tag is set based on the data upload strategy; if the data upload strategy is a timed upload strategy or a stable mode in a dynamic upload strategy, the dosimeter's location is updated every 60 seconds; if the data upload strategy is an early warning mode in a dynamic upload strategy, the dosimeter's location is updated every 30 seconds; if the data upload strategy is an emergency mode in a dynamic upload strategy, the dosimeter's location is updated every 1 second; the dosimeter obtains the location tag via WiFi fingerprint.

[0010] Preferably, when the dynamic upload strategy is in emergency mode, the radiation data packet also includes a leak identifier, which is used to mark the current leak location; if the same location tag triggers the emergency mode continuously, the dosimeter will mark the location as a potential leak point as a leak identifier; the server triggers an emergency response at the corresponding location based on the leak identifier in the radiation data packet.

[0011] Preferably, when the dynamic upload strategy is in emergency mode, the dosimeter triggers a local audible and visual vibration alarm and an emergency mode wireless broadcast; the emergency mode wireless broadcast is used to send a high-frequency alarm signal to the server, and the high-frequency alarm signal is used to trigger the server to aggregate the dose rate according to the location tag, generate a regional risk map or automatically push alarm information to the access control system to block the leakage area passage.

[0012] Preferably, the two-level ACK response includes a data-level ACK and a heartbeat-level ACK. The data-level ACK contains the highest sequence number of the radiation data packets received by the server. The heartbeat-level ACK is transmitted by the server to the dosimeter every 30 seconds and is used to maintain long-term connection monitoring.

[0013] Preferably, based on the dual-level ACK response and the signal strength of the dosimeter, the criteria for determining whether the dosimeter is disconnected are: the signal strength of the dosimeter is less than the warning threshold and the dual-level ACK times out at the same time; the criteria for determining the dual-level ACK timeout are: no data-level ACK is received or no heartbeat-level ACK is received for two consecutive times.

[0014] This invention also provides a data continuation, location tracking, and power consumption management system for a personal dosimeter, including a reader matching module, a data acquisition and encapsulation module, a data transmission module, a disconnection detection module, a data caching module, and a data filtering and retransmission module. The reader matching module is used to match the dosimeter with readers at the entrance and exit of the control area. The data acquisition and encapsulation module is used to acquire radiation data in real time and encapsulate it into radiation data packets. The data transmission module is used to transmit the radiation data packets to a server and receive a two-level ACK response from the server. The strategy for uploading the radiation data packets includes a timed upload strategy and a dynamic upload strategy. The disconnection detection module is used to determine whether the dosimeter is disconnected based on the two-level ACK response and the signal strength of the dosimeter. The data caching module is used to cache the radiation data packets generated when the dosimeter is disconnected. The data filtering and retransmission module is used to filter out missing radiation data packets in the server and retransmit the missing radiation data packets to the server.

[0015] Preferably, it also includes an emergency response module, which is used to trigger a local audible and visual vibration alarm and an emergency mode wireless broadcast at the dosimeter end, and to trigger the server to aggregate the dose rate according to the location tag, generate a regional risk map or automatically push alarm information to the access control system to block the passage of the leak area.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention enables the resumption and integrity assurance of dose data transmission after interruptions in the complex environment of nuclear power plants, solving the problem of data discontinuity caused by wireless signal interruptions and the inability of servers to trace the complete dose history within a working cycle. It also enables the correlation between dose data and personnel location information, assisting in the rapid location of radiation sources when dose exceeds the threshold, improving emergency response efficiency, reducing manual intervention, and lowering the operational risks of nuclear power plants. Furthermore, it can dynamically adjust the data upload strategy based on the dose change rate, balancing real-time performance and endurance requirements, adapting to dose change scenarios, ensuring timely and accurate critical data, and extending the equipment's battery life.

Based on the embodiments of the present invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should fall within the scope of the technical content disclosed in the present invention. It should be noted that in this specification, relational terms such as "first" and "second" are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0022] This invention provides an embodiment: such as Figure 1 As shown, a method for data transmission continuation, location tracking, and power consumption management of a personal dosimeter includes the following steps:

[0023] S1: Match the infrared / NFC reader at the entrance of the nuclear power plant control area, enter the nuclear power plant control area, automatically activate and load the preset data upload strategy; the data upload strategy includes a timed upload strategy and a dynamic upload strategy.

[0024] The timed upload strategy transmits radiation data packets based on a fixed upload period; the dynamic upload strategy dynamically adjusts the upload period based on the dose change rate to transmit radiation data packets, which is suitable for low dose rate stable scenarios; the dose change rate is based on the real-time dose detected by the dosimeter and is obtained through a sliding window algorithm.

[0025] S2: Obtain radiation information along the path during activity in the controlled area and encapsulate it to obtain a radiation data packet; the radiation data packet includes a timestamp, an incrementing sequence number, a dose rate, a cumulative dose, and a location tag; the dosimeter obtains the location tag via WiFi fingerprint. The timestamp is synchronized with the server time each time the device enters the controlled area; the incrementing sequence number is a 32-bit unique identifier, counted cyclically; the dose rate is in microsieverts per hour (μSv / h) with an accuracy of 0.1 μSv / h; the cumulative dose is in microsieverts (μSv) with an accuracy of 0.1 μSv; the radiation data packet is encrypted and transmitted to the server.

[0026] S3: Based on the data upload strategy, the radiation data packet is sent to the server; the radiation data packet is used to trigger the server to generate a two-level ACK response; each time the dosimeter uploads a data packet, it will be appended with a unique incrementing sequence number and a timestamp, and the server will return an ACK signal carrying the sequence number to confirm the reception status.

[0027] The dynamic upload strategy includes a stable mode, an early warning mode, and an emergency mode. When the dose change rate is less than 5%, the corresponding dynamic upload strategy is the stable mode, in which a radiation data packet is uploaded every 60 seconds, consistent with the upload cycle in the timed upload strategy. When the dose change rate is greater than or equal to 5% and less than 20%, the corresponding dynamic upload strategy is the early warning mode, in which a radiation data packet is uploaded every 30 seconds. When the dose change rate is greater than or equal to 20%, the corresponding dynamic upload strategy is the emergency mode, in which a radiation data packet is uploaded every 1 second.

[0028] The update frequency of the location tag is set based on the data upload strategy. If the data upload strategy is a timed upload strategy or a stable mode in a dynamic upload strategy, the dosimeter's location is updated every 60 seconds. If the data upload strategy is an early warning mode in a dynamic upload strategy, the dosimeter's location is updated every 30 seconds. If the data upload strategy is an emergency mode in a dynamic upload strategy, the dosimeter's location is updated every 1 second.

[0029] S4: Receive the two-level ACK response, and determine whether the dosimeter is disconnected based on the two-level ACK response and the signal strength of the dosimeter; if it is determined to be connected, return to step S3; if it is determined to be disconnected, execute step S5.

[0030] The two-level ACK response includes a data-level ACK and a heartbeat-level ACK. The data-level ACK contains the highest sequence number Nmax of the radiation data packet received by the server, which is used to mark data integrity. The heartbeat-level ACK is transmitted by the server to the dosimeter once every 30 seconds and is used to maintain long-term connection monitoring.

[0031] Based on the dual-level ACK response and the signal strength of the dosimeter, the criteria for determining whether the dosimeter is disconnected are: the signal strength of the dosimeter is less than the warning threshold and the dual-level ACK times out at the same time; the criteria for determining the dual-level ACK timeout are: no data-level ACK is received or no heartbeat-level ACK is received for two consecutive times; the warning threshold is -90dBm (decibels milliwatts).

[0032] S5: Based on the data upload strategy corresponding to the previous radiation data packet, continue to store the new radiation data packet in the local cache of the dosimeter, and mark it with an incrementing sequence number Nmax+1~Nmax+X, where X is the number of radiation data packets in the local cache during the disconnection period; until the signal is restored and the latest data-level ACK is received from the server;

[0033] S6: Compare the sequence number in the latest data-level ACK with the sequence number in the local cache of the dosimeter to filter out the missing radiation data packets (Nmax+1 to Nmax+X).

[0034] S7: The missing radiation data packets are retransmitted to the server in chronological order, and the server performs conflict detection (based on dual verification of timestamp and sequence number); the dosimeter clears the uploaded cached data; and returns to step S3;

[0035] S8: After the nuclear power plant control area operation is completed, match the reader at the exit of the nuclear power plant control area and leave the control area.

[0036] In addition, when the dynamic upload strategy is in emergency mode, the radiation data packet also includes a leak identifier, which is used to mark the current leak location; the dosimeter has a built-in low-power MCU that performs the following analysis in real time: if the same location tag triggers the emergency mode continuously, the dosimeter will mark the location as a potential leak point as a leak identifier; the server triggers an emergency response at the corresponding location based on the leak identifier in the radiation data packet.

[0037] When the dynamic upload strategy is in emergency mode, the dosimeter triggers a local audible and visual vibration alarm and an emergency mode wireless broadcast. The local audible and visual vibration alarm uses a buzzer, LED, and vibration to alert personnel to evacuate. The emergency mode wireless broadcast is used to send a high-frequency alarm signal to the server. The high-frequency alarm signal is used to trigger the server to aggregate dose rates by location tags, generate a regional risk map, or automatically push alarm information to the access control system to block the passage to the leak area.

[0038] With the support of a location-based tracing and dynamic power consumption management system, when the dose rate changes abruptly, the dosimeter will simultaneously upload dose data and location tags at high frequency to assist the server in building a high-precision leak point model. Furthermore, the dosimeter will independently complete dynamic policy triggering, leak location tag binding, and local alarms, achieving rapid response through localized analysis, reducing reliance on the cloud, and enhancing the dosimeter's autonomous perception, decision-making, and execution capabilities.

[0039] This invention also provides a data transmission, location tracking, and power consumption management system for a personal dosimeter, including a reader matching module, a data acquisition and encapsulation module, a data transmission module, a disconnection detection module, a data caching module, a data filtering and retransmission module, and an emergency response module. The reader matching module is used to match the dosimeter with readers at the entrance and exit of the control area. The data acquisition and encapsulation module is used to acquire radiation data in real time and encapsulate it into radiation data packets. The data transmission module is used to transmit the radiation data packets to the server and receive a two-level ACK response from the server. The strategy for uploading the radiation data packets includes a timed upload strategy and a dynamic upload strategy. The disconnection detection module is used to determine whether the dosimeter is disconnected based on the two-level ACK response and the signal strength of the dosimeter. The data caching module is used to cache the radiation data packets generated when the dosimeter is disconnected. The data filtering and retransmission module is used to filter out missing radiation data packets in the server and retransmit the missing radiation data packets to the server. The emergency response module is used to trigger a local audible and visual vibration alarm and an emergency mode wireless broadcast at the dosimeter, and to trigger the server to aggregate dose rates according to location tags, generate an area risk map, or automatically push alarm information to the access control system to block the leakage area passage.

[0040] This invention uses a unique incremental sequence number and ACK confirmation mechanism, which enables the server to accurately identify missing data segments. Combined with a dynamic caching strategy during disconnection, the data loss rate is reduced from the traditional 30% to below 5%. After communication is restored, the sequence number-based retransmission logic ensures that historical dose data is continuously traceable.

[0041] By using signal strength threshold (RSSI < -90dBm) early warning and dual-level ACK detection (data level + heartbeat level), the problem of misjudgment caused by signal fluctuations in the metal shielding area of ​​nuclear power plants is solved. RSSI is the signal strength. During disconnection, data is cached according to a dynamic strategy to adapt to different scenario requirements (such as high-frequency storage in high-radiation areas). A conflict detection algorithm (timestamp + sequence number dual verification) is used to avoid data duplication or omission, thereby improving server processing efficiency.

[0042] Based on a dynamic upload strategy using dose change rate, data is uploaded every second in emergency mode, enabling the server to construct a second-level radiation leak timeline and reducing leak source location time to within 2 minutes. Location tags are bound to dose data in real time, and the server generates regional heat maps to quickly pinpoint leak points, reducing manual investigation workload by 90%. In stable mode, data is uploaded at 60-second intervals, reducing power consumption by 60%. In emergency mode, only the detector and communication module are activated, avoiding redundant energy consumption. After comprehensive optimization, the device's battery life is extended from the traditional 8 hours to over 48 hours, meeting the long-term operation requirements of nuclear power plants. The dosimeter has a built-in low-power MCU performing edge computing. When the same location tag continuously triggers emergency mode, it autonomously marks potential leak points and broadcasts alarms, reducing reliance on cloud servers.

[0043] The following detailed description, in conjunction with specific embodiments, further illustrates the point:

[0044] 1. Signal interruption scenario:

[0045] Scenario: Staff wearing dosimeters enter the underground level of a nuclear power plant to work, and the WiFi signal is interrupted for 10 minutes during the work period.

[0046] Equipment Response: The dosimeter detects a signal strength RSSI < -90dBm, triggering a signal warning. After sending the Nth data item, the dosimeter does not receive a data-level ACK from the server. At this point, the device determines it is in a disconnected state. The dosimeter begins caching data (during this period, the device remains in stable mode using a 60-second timed upload strategy, with cached data sequence numbers from N to N+10). Ten minutes later, the staff returns to the signal coverage area, and the dosimeter receives a data ACK from the server (at this time, the first sequence number in the server's returned data ACK is N-1, and the last sequence number is N+10).

[0047] Results: The radiation data packets with sequence numbers N to N+10 were automatically retransmitted in sequence. The server verified the timestamps and sequence numbers, reconstructed the complete dose curve, and no data was missing.

[0048] 2. Emergency response to dose mutation:

[0049] Scenario: Staff wearing dosimeters enter the leak area from a low-dose zone (0.1 μSv / h), and the dose rate rises to 500 μSv / h within 5 seconds.

[0050] Dosimeter Response: 1. If the dosimeter detects a dose change rate ≥20%, it triggers the emergency mode (uploads data every second); 2. It uploads radiation data packets every second; 3. Local audible, visual, and vibration alarms prompt personnel to evacuate.

[0051] Server response: 1. Receive high-frequency radiation data packets, aggregate dose rates by location tags, and generate a regional risk map; 2. Automatically push alarm information to the access control system, block the passage of the leak area, and prevent radiation spread.

[0052] Edge computing prediction: The dosimeter detects that the label at the same location triggers the emergency mode twice in a row, marking it as a potential leak point.

[0053] This invention moves from "passive response" to "active prediction," achieving autonomous perception of dose mutations and prediction of leaks through dynamic strategies and edge computing, breaking through the lagging mode of traditional manual analysis. It moves from "data fragmentation" to "spatiotemporal fusion," binding location tags to dose data in real time to construct a three-dimensional "time-space-dose" correlation model, overcoming the limitation of traditional dosimeters that only record cumulative doses. It moves from "high power consumption and rigidity" to "intelligent adaptation," dynamically adjusting the upload frequency and module power consumption to balance real-time performance and battery life, resulting in a 6-fold increase in battery life.

[0054] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
