Description

Technical Field

[0002] In nuclear power plants, nuclear facilities and radioactive workplaces, gamma dose rate meters are key equipment for real-time monitoring of environmental radiation intensity.

[0003] In existing technologies, wired transmission methods have complex wiring, poor flexibility, and are susceptible to environmental interference. Wireless transmission technologies (such as WiFi or 5G) have unstable signals and are difficult to adapt to complex environments. The battery life is insufficient, making it difficult to meet the needs of long-term continuous monitoring. The measuring range is limited and cannot meet the monitoring needs of low and high dose rates at the same time. The lack of NFC function makes it difficult to achieve rapid configuration and data exchange. Although there are some wireless transmission dose rate meters, they mostly use a single communication mode (only supports WiFi or 4G), and the antenna layout is unreasonable, which cannot take into account both signal strength and device portability. In addition, high and low range detection usually requires switching between different devices, which is inefficient. Summary of the Invention

DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] The following combination Figures 1-4 The present invention describes a gamma dose rate meter with NFC function and wireless data transmission.

[0025] Figure 1 This is a structural schematic diagram of a gamma dose rate meter with NFC function and wireless data transmission provided by an embodiment of the present invention.

[0026] Figure 2 This is a schematic diagram of the overall structure of a gamma dose rate meter device with NFC function and wireless data transmission provided by an embodiment of the present invention.

[0027] Figure 3 The present invention provides a system architecture block diagram of a gamma dose rate meter with NFC function and wireless data transmission.

[0028] like Figure 1-Figure 3As shown, an embodiment of the present invention provides a gamma dose rate meter with NFC function and wireless data transmission, including a shell design module, a detection module, a wireless communication module, an NFC module, a power management module and a user interaction module.

[0029] The shell design module is used to manufacture the shell of a gamma dose rate meter using composite materials and equip it with a display screen.

[0030] The housing design module includes a material forming unit, a display integration unit, and a protective treatment unit. The material forming unit uses a compression molding process to place composite materials into a specific mold and solidify the composite materials under preset conditions to produce a housing shape that meets the design requirements of the gamma dose rate meter. The display integration unit uses welding and wiring connection techniques to electrically connect the display to the control circuitry within the housing and seals the display and housing mounting points with sealant. The protective treatment unit sprays a protective paint on the housing surface after molding.

[0031] Made of high-strength, radiation-resistant, and electromagnetic interference-resistant composite materials, it ensures stable operation in harsh environments. The interior of the device housing is rationally laid out, and each module is connected by high-reliability connectors to ensure a stable structure.

[0032] Select the appropriate composite material based on the operating environment and performance requirements of the gamma dose rate meter. Dry the composite material to remove moisture from it to avoid bubbles caused by evaporation of moisture during the molding process, which will affect the quality of the shell. Accurately design the shape and size of the mold based on the shell design requirements of the gamma dose rate meter. Place the pre-treated composite material into the mold cavity in a certain manner to ensure that the material is evenly distributed. Close the upper and lower molds of the mold, and apply a certain amount of pressure through the press so that the composite material in the mold fills the cavity under the action of pressure. While applying pressure, heat the composite material through the heating system in the mold. When the composite material is completely cured, lower the mold temperature. After the temperature drops to a certain level, open the mold and remove the molded shell from the mold.

[0033] The detection module is used to use a dual-monomer Geiger tube detector to cover low range and high range, obtain detection signals, and adaptively switch the detection range.

[0034] The detection module consists of a detector assembly unit, a signal conversion unit, and a range switching unit. The detector assembly unit is used to mount the low-range and high-range Geiger tube detectors on the detection module's bracket according to a preset physical layout and connect them to the signal processing circuit via wiring. The signal conversion unit uses a preamplifier to amplify the electrical signal output by the detector and then converts the analog signal into a digital signal using an analog-to-digital converter. The range switching unit switches the detector's operating mode via a relay control circuit based on the signal processing circuit's analysis of the digital signal.

[0035] It uses dual-monomer Geiger tube detectors, which are installed in parallel at the top of the shell in staggered phases to improve detection efficiency and accuracy. They cover low range (0.01μSv / h~10mSv / h) and high range (10mSv / h~100mSv / h) respectively. The range is automatically switched by the control unit to avoid manual intervention.

[0036] Based on the measurement range and accuracy requirements of the gamma dose rate meter, appropriate low-range and high-range single-body Geiger tube detectors are carefully selected. The low-range detector must have high sensitivity to accurately measure low-dose-rate gamma rays; the high-range detector must be able to withstand high-dose-rate radiation without saturation.

[0037] Before installation, the selected detectors are rigorously tested for performance. Tests include detection efficiency, background count rate, energy response, and other indicators to ensure that the detector performance meets design requirements.

[0038] Design the detector module's bracket based on the detector's dimensions, physical layout requirements, and installation space limitations. The bracket must be strong and stable enough to keep the detector in place during use and protect it from vibration and impact.

[0039] Use appropriate materials (such as aluminum alloy, engineering plastics, etc.) and processing technology (such as machining, injection molding, etc.) to manufacture the bracket. Ensure the processing accuracy of the bracket and ensure that the position and size of the detector mounting hole meet the design requirements.

[0040] According to the preset physical layout plan, accurately install the low-range and high-range detectors on the bracket. When laying out, consider the mutual interference between the detectors to avoid counting errors caused by too close distance between the detectors.

[0041] Choose wires or cables with good conductivity, insulation and anti-interference capabilities as the connection line. According to the output signal characteristics and transmission distance of the detector, reasonably select the specifications and models of the line.

[0042] Connect the detector's output pins to the signal processing circuit's input interface through wiring. Pay attention to soldering quality during the connection process to ensure that the solder joints are secure and free of cold solder joints and short circuits. Also, organize and secure the wiring to prevent it from loosening or becoming entangled during use.

[0043] The circuit structure of the preamplifier is designed based on the characteristics of the detector's output signal (such as signal amplitude, frequency range, etc.). The preamplifier is usually composed of a low-noise, high-gain operational amplifier to improve the amplitude and quality of the signal.

[0044] After the preamplifier circuit is assembled, its parameters are debugged. The debugging content includes gain adjustment, bandwidth adjustment, noise suppression, etc., to ensure that the preamplifier can effectively amplify the weak electrical signal output by the detector.

[0045] The weak electrical signal output by the detector is input to the input of the preamplifier through the connecting line. Since the detector output signal is very weak, usually at the millivolt or even microvolt level, it needs to be initially amplified by the preamplifier.

[0046] The preamplifier amplifies the input signal, raising the signal amplitude to a range suitable for processing by the analog-to-digital converter. The amplification factor is adjusted based on the size of the detector output signal and the input requirements of the analog-to-digital converter.

[0047] Select an appropriate analog-to-digital converter (ADC) based on the accuracy and speed requirements for signal processing. Consider parameters such as the ADC's resolution, sampling rate, and input range to ensure it can accurately convert analog signals into digital signals.

[0048] Configure the selected ADC and set parameters such as sampling frequency and reference voltage. Communicate with the ADC through a microcontroller or other control circuit to control the ADC and read data.

[0049] The ADC samples the amplified analog signal according to the set sampling frequency and discretizes the continuous analog signal.

[0050] The ADC quantizes the sampled signal, converting the analog signal's amplitude into a digital code. This quantization process introduces a certain amount of quantization error, so an appropriate resolution is necessary to minimize this error. Finally, the quantized digital code is encoded and output as a digital signal.

[0051] The microcontroller or signal processing chip communicates with the analog-to-digital converter to collect the converted digital signal. The signal processing circuit analyzes and processes the collected digital signal. Based on the preset range threshold, it determines whether the currently detected dose rate is in the low or high range. For example, if the dose rate is below a certain set value, it is judged to be in the low range; if the dose rate is above the set value, it is judged to be in the high range.

[0052] The relay control circuit consists of a relay, a driver chip, and a power supply circuit. The relay acts as a switching element, switching the detector's operating mode. The driver chip controls the relay's closing and opening. The power supply circuit provides power to the relay and driver chip.

[0053] According to the rated voltage, current and other parameters of the relay, the output power of the driver chip and the output voltage of the power supply circuit are designed to ensure that the relay can work normally.

[0054] When the signal processing circuit determines that a range switch is required, the microcontroller or signal processing chip outputs a control signal to the relay driver chip. The level of the control signal determines whether the relay is closed or open.

[0055] The relay driver chip drives the relay according to the level of the control signal. When the low range needs to be switched to the high range, the relay is energized, switching the working circuit of the high range detector to the high range; when the high range needs to be switched to the low range, the relay is energized, reverting to the working circuit of the low range detector.

[0056] The wireless communication module is used to transmit the detection signal using a single signal transmission mode.

[0057] The wireless communication module includes a signal modulation unit, a wireless transmission unit, and a communication protocol management unit. The signal modulation unit modulates digital signals using a preset modulation algorithm. The wireless transmission unit transmits the modulated signal as electromagnetic waves via an antenna. The communication protocol management unit integrates the preset communication protocol stack into the communication chip to manage and control the signal transmission process.

[0058] Adopting WiFi or 5G single signal transmission mode, users can select one of the modes according to environmental conditions to ensure the stability and flexibility of data transmission.

[0059] The antenna adopts a 4-antenna simultaneous networking method, built into both sides of the shell, using high-performance antenna materials, and arranged vertically with the Geiger tube to optimize signal reception, avoid electromagnetic interference of metal detectors on the antenna, and improve transmission reliability.

[0060] Select an appropriate modulation algorithm based on the specific requirements of wireless communication, such as transmission rate, anti-interference capability, and bandwidth utilization. For example, for scenarios with high transmission rate requirements and limited bandwidth resources, an orthogonal frequency division multiplexing modulation algorithm may be selected; whereas for simple short-distance communications, simpler modulation algorithms such as amplitude keying and frequency shift keying may be more appropriate.

[0061] To improve the signal's anti-interference and error-correction capabilities, the input digital signal is encoded. Common encoding methods include convolutional codes, turbo codes, and low-density parity-check codes. The encoding process adds redundant information to the original digital signal, enabling the receiving end to detect and correct errors that occur during transmission.

[0062] Interleaving the coded digital signal disrupts the signal order, which can disperse sudden errors, reduce the impact of continuous errors on decoding, and further improve the system's anti-interference ability.

[0063] Based on the selected modulation algorithm, the preprocessed digital signal is mapped to the corresponding modulation symbols. The mapped modulation symbols are multiplied by the carrier signal to modulate the carrier signal. The modulated signal contains the information of the original digital signal and has spectral characteristics suitable for wireless transmission.

[0064] Select an appropriate power amplifier based on the required transmit power. Power amplifier performance metrics include gain, linearity, and efficiency. Ensure the power amplifier can amplify the modulated signal to a sufficient power level to meet the required distance and coverage for wireless transmission.

[0065] The modulated signal is fed into the input of a power amplifier, where it is amplified and output as a higher-power signal. During the amplification process, it is important to carefully control the power amplifier's operating state to avoid nonlinear distortion that can affect signal quality.

[0066] The amplified signal is filtered through a filter to produce a pure transmit signal. The filtered signal spectrum is more concentrated and meets the spectrum specifications of wireless communications.

[0067] Select an appropriate antenna based on the wireless communication frequency band, radiation pattern, gain, and other requirements. The filtered transmit signal is transmitted to the antenna via a feeder. The antenna converts the electrical signal into electromagnetic waves and radiates them into space. The transmit signal propagates through space and reaches the receiver.

[0068] Figure 4 1 is a schematic diagram of the NFC measurement process in an embodiment of the present invention.

[0069] like Figure 4As shown, the NFC module is used to obtain 5G positioning information and use the near-field communication tag information to correct the 5G positioning information to achieve in-factory positioning.

[0070] The NFC module includes a 5G positioning acquisition unit, a tag information reading unit, and a positioning correction unit. The 5G positioning acquisition unit receives 5G base station signals via a built-in 5G positioning chip and calculates the device's location using a triangulation algorithm. The tag information reading unit uses an NFC reader to communicate with pre-installed near-field communication tags within the factory, reading the location calibration information stored in the tags. The positioning correction unit compares and analyzes the acquired 5G positioning information with the near-field communication tag information and corrects the 5G positioning information using a weighted average algorithm.

[0071] The NFC module is located in the lower right corner of the instrument. This position makes it convenient for users to perform near-field communication operations when holding the device, while avoiding accidental touches on other functional areas.

[0072] Combined with the precise information provided by the NFC tag during use, 5G positioning and the NFC tag verify each other to realize the in-factory positioning function.

[0073] The NFC function supports rapid device configuration and data exchange, improving operational convenience.

[0074] When the device starts up, it first checks whether the hardware connection between the 5G positioning chip and other components is normal. The positioning chip will perform a self-test to ensure that its internal circuits and functional modules are in normal working condition, such as checking whether the clock signal and power supply are stable.

[0075] The 5G positioning chip is configured based on the device's 5G network environment and application requirements. The 5G positioning chip turns on its antenna and searches for surrounding 5G base station signals within a preset frequency band. After receiving the 5G base station signal, the positioning chip demodulates the signal and converts the RF signal into a digital signal. The digital signal is then decoded to extract information such as the base station identifier, timestamp, and signal strength. To achieve triangulated positioning, the positioning chip collects signal information from at least three different 5G base stations. By continuously monitoring and receiving signals from surrounding base stations, it obtains the distance between each base station and the device. Distance information can be estimated based on signal propagation time or signal strength attenuation.

[0076] Using the collected distance information from multiple base stations and the known coordinates of the base stations, the positioning chip uses a triangulation algorithm to calculate the device's location. This algorithm, based on geometric principles, determines the device's location by finding the intersection of multiple circles. Specifically, a circle is drawn with each base station as the center and the distance between the device and the base station as the radius. The intersection of these circles represents the device's probable location.

[0077] Before using the NFC reader, check its hardware to ensure that components such as the antenna and RF module are working properly.

[0078] The NFC reader / writer transmits a radio frequency signal of a specific frequency through its antenna to search for near-field communication tags within its effective operating range. This signal activates the circuit in the tag, putting it into operation.

[0079] When a near-field communication tag receives a signal from a reader, it responds according to its own protocol and procedures, returning a signal containing its own identification and data. The NFC reader monitors the surrounding signals in real time and detects the tag's response signal.

[0080] Once the NFC reader detects the tag's response signal, it establishes a communication connection with the tag and performs authentication and data encryption according to the communication process specified in the protocol to ensure the security and reliability of communication.

[0081] After establishing a communication connection, the NFC reader sends a read command to the tag, requesting the location calibration information stored in the tag. Upon receiving the command, the tag sends the stored location information to the reader. The reader decodes and verifies the data to ensure that it is accurate.

[0082] The positioning correction unit obtains the 5G positioning information of the device from the 5G positioning acquisition unit, and simultaneously obtains the position calibration information of the near-field communication tag from the tag information reading unit.

[0083] Since 5G positioning information and tag position calibration information may use different data formats and coordinate systems, the positioning correction unit needs to convert the format of this information and unify the coordinate system.

[0084] Compare the 5G positioning information with the NFC tag's position calibration information to calculate the position deviation between the two. Based on the position deviation, analyze the possible causes of the error.

[0085] Different weights are assigned to 5G positioning information and NFC tag information based on their reliability and accuracy. Generally speaking, if the 5G positioning signal is stable and the surrounding environment has minimal interference, the 5G positioning information can be weighted higher; if the NFC tag is accurately installed and in good condition, the tag information can be weighted higher. Weights can be determined based on empirical values ​​or dynamically adjusted through machine learning algorithms.

[0086] A weighted average algorithm is used to calculate the weighted average of 5G positioning information and near-field communication tag information.

[0087] The power management module is used to provide power supply and implement intelligent power consumption management using optimized circuit algorithms.

[0088] The power management module consists of a power supply unit, a power consumption monitoring unit, and an intelligent control unit. The power supply unit uses a rechargeable battery as its power source and controls battery charging through a charge management circuit. A voltage conversion circuit converts the battery voltage to the device's required operating voltage. The power consumption monitoring unit uses current and voltage sensors within the circuit to monitor the device's current and voltage consumption in real time and transmits the data to a microcontroller for analysis. The intelligent control unit uses the microcontroller to intelligently control the device's power consumption using optimized circuit algorithms based on the data provided by the power consumption monitoring unit.

[0089] The device uses a single-row, six-cell 18650 lithium battery pack with a capacity of ≥12,000 mAh. Highly conductive connectors connect the cells to ensure stable current transmission and support hot-swappable replacement. The battery pack is integrally encapsulated on the bottom of the device for easy replacement and maintenance.

[0090] By optimizing circuit design and algorithms, the device is equipped with 5G deep sleep function, realizing intelligent power consumption management and extending battery life.

[0091] Select an appropriate rechargeable battery based on the gamma dose rate meter's power requirements, operating time requirements, and size limitations. Common rechargeable battery types include lithium-ion batteries and nickel-metal hydride batteries.

[0092] When the device is connected to an external power source, the charge management circuit first detects the current status of the battery, including battery voltage, remaining power, etc. Through the built-in battery monitoring chip, it obtains the real-time battery parameters and determines whether the battery needs to be charged and what charging stage it is in.

[0093] The charge management circuit precisely controls the charging current and voltage based on the battery's condition and type. During the trickle charge phase, the battery is pre-charged with a lower current to prevent damage to over-discharged batteries from being directly charged with a high current. During the constant current charge phase, a constant charge current is maintained to quickly replenish the battery. When the battery voltage approaches the full charge voltage, the constant voltage charge phase begins, reducing the charge current to prevent overcharging.

[0094] The charge management circuit has multiple protection functions, such as overcharge protection, overcurrent protection, and overheat protection. When it detects that the battery voltage exceeds the safety threshold, the charging current is too high, or the battery temperature is too high during charging, the charge management circuit will automatically cut off the charging circuit to ensure battery safety.

[0095] The output voltage of the voltage conversion circuit is determined based on the operating voltage requirements of each module of the gamma dose rate meter. Different modules may require different voltages. For example, a microcontroller may require a 3.3V operating voltage, while some sensors may require a 5V operating voltage.

[0096] Use appropriate voltage conversion chips (such as DC-DC converters and LDO regulators) to convert the battery voltage into the operating voltage required by the device's various modules. DC-DC converters are suitable for applications requiring a wide voltage conversion range and high power conversion efficiency; LDO regulators are suitable for applications requiring high output voltage accuracy and low output current.

[0097] Voltage stability control: The voltage conversion circuit monitors the output voltage in real time through a feedback mechanism and automatically adjusts the conversion parameters according to load changes to ensure the stability of the output voltage.

[0098] Install current sensors on the main power supply line of the equipment or on the power supply lines of each module to accurately measure the current consumption.

[0099] Connect the voltage sensor to the power input of the device and the power supply of each module to monitor voltage changes in real time.

[0100] Connect the output signals of the current sensor and voltage sensor to the analog input port of the microcontroller through appropriate lines.

[0101] The current sensor and voltage sensor output analog signals, which are sampled by the microcontroller through the built-in analog-to-digital converter (ADC).

[0102] The microcontroller pre-processes the collected digital signals, including filtering, calibration and other operations.

[0103] The pre-processed data is transmitted to the main processing unit of the microcontroller through the internal bus or communication interface of the microcontroller.

[0104] The microcontroller analyzes the stored current and voltage data to calculate the real-time and average power consumption of the device.

[0105] The microcontroller receives real-time current, voltage, and power consumption data from the power monitoring unit.

[0106] The received data is further processed, such as calculating the rate of change of power consumption, analyzing the relationship between power consumption and device operating status, etc. Through data processing, valuable information for power consumption control is extracted.

[0107] Based on the device's characteristics and power consumption control objectives, select appropriate optimization circuit algorithms, including dynamic voltage scaling (DVS), dynamic frequency scaling (DFS), and sleep mode management. For example, when the device is in a low-load state, the DVS algorithm can be used to reduce the supply voltage and power consumption; when the device is inactive for a period of time, it can enter sleep mode and shut down unnecessary modules.

[0108] The selected circuit optimization algorithm is programmed into the microcontroller. Based on the power consumption monitoring data, the algorithm adjusts the device's operating parameters in real time, such as adjusting the output voltage of the voltage conversion circuit, changing the microcontroller's operating frequency, and controlling the on / off state of the module.

[0109] The microcontroller makes control decisions in real time based on the calculation results of the optimized circuit algorithm and the current power consumption data.

[0110] The microcontroller converts control decisions into specific control signals and sends them to the corresponding circuit modules or device components.

[0111] After the control is executed, the microcontroller continues to monitor the changes in the device's power consumption and evaluate the control effect.

[0112] The user interaction module is used to provide users with an intuitive operation interface, supporting users to set parameters and select modes through the display screen.

[0113] The user interaction module includes an interface display unit, an input operation unit, and a feedback prompt unit. The interface display unit uses a graphics processor to convert the data and settings collected by the device into a visual graphical interface and display it on the display. The input operation unit integrates a touch sensor on the display screen, allowing parameter settings and mode selection to be performed via the touch screen. The touch signal is processed and transmitted to the device control circuit. The feedback prompt unit is used to emit an audible prompt through a buzzer when the user operation is successful or an abnormality occurs in the device, and the corresponding text prompt information is displayed on the display screen.

[0114] Equipped with a large, high-definition display screen, it displays real-time information such as gamma ray dose rate, battery power, communication status, and range mode.

[0115] The simple and clear design of operation buttons allows users to quickly set parameters, reference data and perform equipment maintenance.

[0116] The graphics processing unit (GPU) establishes a communication connection with the device's data acquisition system and obtains data collected by the device, such as gamma dose rate values ​​and device operating status parameters, from the data acquisition module according to a certain frequency and protocol. At the same time, it reads user settings, such as measurement mode and alarm thresholds, from the device's storage module.

[0119] Based on the parsed data and pre-designed interface layout, the GPU uses graphics rendering algorithms to draw various interface elements. For data display, collected data is rendered on the interface in the form of numbers, charts, and other formats; for settings, information is presented in the form of text, option boxes, and other formats. During the drawing process, visual effects such as color, fonts, and icons are considered to improve the readability and aesthetics of the interface.

[0120] Converting the generated graphical interface data into electrical signals that the display can recognize involves encoding and modulating the image data to make it conform to the interface standards and driver requirements of the display.

[0121] The converted signal is transmitted to the display through the display's driver circuit. The display controls the light-emitting state of the pixels based on the received signal, thereby displaying the graphical interface.
