Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, this embodiment proposes an intelligent electronic work card with a radiation dose monitoring function, including a shell 1, a card slot 2 for storing the employee's work card is provided on one side of the shell 1, a sling hole 3 for fixing a sling is provided on the shell 1, a small radiation monitoring device is provided in the shell 1, and a buzzer 4 is embedded on one side of the shell 1, and the buzzer 4 is electrically connected to the radiation monitoring device.

[0022] The housing 1 provides structural support and protection for the entire smart electronic ID card, housing the small radiation monitoring device and other electronic components. This housing ensures the card's robustness and durability, while also protecting the delicate instruments within from external impact and damage. The card slot 2 holds the employee's ID card, enabling the smart electronic ID card to not only perform radiation monitoring but also serve as a daily identification tool. Combining the radiation monitoring device with the ID card reduces the need for wear, allowing employees to perform both identification and radiation monitoring with a single device. Stopper protrusions 21 are located on either side of the card slot 2 to prevent the ID card from falling out. The strap hole 3 is used to secure a strap, allowing the smart electronic ID card to be hung around the employee's neck, ensuring portability and ease of use during work. The small radiation sensor, a core component of the ID card, monitors the employee's radiation dose in real time and records the data. Its miniaturized design keeps the ID card lightweight and minimizes the burden on employees. Compared to traditional, larger radiation dosimeters, the miniaturized design enhances portability, making it easier for employees to wear around the clock, improving the timeliness and accuracy of radiation monitoring. The buzzer 4 is electrically connected to the small radiation monitoring device. When it detects excessive radiation, it sounds an audible alarm, reminding the wearer to take protective measures. The built-in buzzer 4 instantly sounds an alarm when radiation exceeds the standard, enhancing the active safety protection function of the work badge, allowing employees to immediately recognize danger and respond. The buzzer 4 can be the PS1240P02BT model, which features an ultra-thin design suitable for ultra-thin work badges and low power consumption.

[0023] In this embodiment, the small radiation monitoring device includes a microcontroller, a digital-to-analog converter, a signal amplifier and filter, a SiPM sensor, a scintillator material, and a power manager. The SiPM sensor faces the scintillator material. The SiPM sensor is electrically connected to the signal amplifier and filter, which is electrically connected to the digital-to-analog converter. The digital-to-analog converter is electrically connected to the microcontroller. The microcontroller, digital-to-analog converter, signal amplifier and filter, and SiPM sensor are all electrically connected to the power manager. The power manager is electrically connected to a power supply, which is detachably connected to the housing 1. A buzzer 4 is electrically connected to the microcontroller and the power manager. A display screen 5 for displaying real-time radiation data is provided on the side of the housing 1 facing away from the card slot 2. The display screen 5 is electrically connected to the power manager and the microcontroller. The microcontroller has an integrated Bluetooth module. The small radiation monitoring device also includes a memory for storing data, which is electrically connected to the power manager and the microcontroller.

[0024] The microcontroller (MCU) is the core control unit of the entire radiation monitoring device. It is responsible for processing signals from the sensor, managing data conversion and storage, controlling the buzzer 4 and display 5, and communicating with external devices such as mobile phones via the Bluetooth module. The microcontroller's high level of integration allows for effective management and coordination of various components, ensuring system efficiency and stability. The built-in Bluetooth module further enhances the device's intelligence, making remote monitoring and management of radiation data more convenient. The MCU can be the Nordic Semiconductor nRF52832, a 32-bit ARM Cortex-M4 microcontroller with Bluetooth Low Energy (BLE) functionality, ideal for portable wireless devices. The signal amplifier and filter (operational amplifier) ​​amplifies the SiPM sensor's output signal while filtering out noise to ensure signal purity and strength. The amplifier and filter module enhances weak radiation signals and eliminates interfering signals, ensuring data accuracy and the system's anti-interference capability. Signal amplification and filtering can be performed using the Texas Instruments OPA657 operational amplifier, a high-speed, low-noise operational amplifier suitable for signal amplification in photodetection circuits. It features high gain bandwidth and low input noise. A digital-to-analog converter (ADC) converts the analog signals from the amplifier and filter into digital signals that can be processed by a microcontroller. This high-precision ADC ensures accurate digitization of the radiation signal, providing a reliable foundation for subsequent data analysis and alarms. The Analog Devices AD7988-5 ADC can be used as the 16-bit, low-power, high-performance SAR ADC with low latency and high accuracy, making it ideal for battery-powered portable applications. SiPM sensors (silicon photomultipliers) are responsible for detecting photon signals emitted by the scintillator material and converting them into electrical signals. SiPM sensors can quickly respond to changes in optical signals, enabling real-time detection of radiation. The compact design of SiPM sensors makes them easy to integrate into small devices, making them suitable for portable radiation monitoring devices. SiPM sensors can detect extremely low photon counts, thereby ensuring sensitive monitoring of low-intensity radiation. SiPM sensors can use the ON Semiconductor MicroFJ-60035-TSV-TR model sensor. This SiPM device has high detection efficiency and a compact package, making it suitable for integration into small devices.When the scintillator material receives radiation, it emits photons, which are detected by the SiPM sensor. The scintillator material's efficient photon emission provides a stable light source signal, providing reliable input for the SiPM sensor and ensuring accurate radiation measurement. The scintillator material can be CsI(Tl) (cesium iodide scintillator), commonly used for gamma-ray and X-ray detection. Its high luminescence efficiency and light output are well matched to the SiPM's detection spectrum. The power manager is responsible for providing a stable power supply to all electronic components and managing the system's overall power distribution. The power manager ensures that each module receives the required power under different operating conditions and optimizes power consumption to extend the device's operating life. The power manager's design for connecting to a removable power supply enhances device maintenance and ease of use. The power manager can be the Texas Instruments TPS61291, a low-input voltage boost converter suitable for battery-powered portable devices, providing a stable voltage output. The power supply is used to power all electronic components. A CR2032 button cell battery can be used, which is compact and has a high capacity, ensuring sufficient operation. A removable battery cover 8 is located within the card slot 2 and is connected to the housing via bolts. The power supply is mounted underneath this cover, facilitating easy replacement. The display 5 displays radiation data in real time, allowing the wearer to directly view their current radiation level. The display 5 can be an SSD1306 model, which features low power consumption, self-luminescence, high contrast, and a wide viewing angle, making it ideal for small portable devices. The memory stores historical radiation dose data for subsequent analysis or report generation. This memory ensures long-term data storage and immediate access, especially during power outages or network disconnections, ensuring data integrity and traceability. The memory can be a Microchip 25LC256 model, a 256Kb serial EEPROM with an SPI interface, suitable for storing small amounts of radiation data and configuration parameters.

[0025] In this embodiment, a power switch 6 and a control button 7 are provided on the side of the housing 1. The power switch 6 is electrically connected to the power manager, and the control button 7 is electrically connected to the microcontroller. The power switch 6 controls the on / off state of the entire radiation monitoring card. It activates or deactivates the device's power supply through the power manager. Through physical switch control, the device can be completely disconnected from the power supply when not in use, preventing unnecessary battery consumption and prolonged standby mode of the circuit. This reduces aging and wear of electronic components and extends the device's battery life. The control button 7 is used to input user commands to the device and can perform various functions, such as switching display information, resetting the device, starting / pausing radiation detection, manually triggering data transmission, and Bluetooth pairing.
