Description

Technical Field

[0001] This invention relates to the field of industrial safety protection technology, specifically to an intrinsically safe smart bracelet that works in conjunction with a safety management platform and a method for comprehensive personnel protection. Background Technology

[0002] Smart bracelets, as wearable smart devices, typically integrate sensors, processors, and communication modules, and are widely used in the civilian sector for health monitoring, exercise recording, and information reminders. However, ordinary civilian smart bracelets have inherent limitations in terms of positioning accuracy, explosion-proof safety, environmental adaptability, and integration of professional functions, and cannot meet the stringent requirements of high-risk industrial scenarios for precise personnel positioning, real-time monitoring of vital signs, proactive early warning of environmental risks, and efficient emergency rescue.

[0003] In existing technologies, personnel safety management in high-risk industries faces several prominent challenges: First, in underground mines or large factory buildings where GPS signals are unavailable, existing RFID or Wi-Fi positioning technologies suffer from low accuracy and insufficient reliability, making it difficult to achieve rapid and accurate personnel location in emergencies. Second, the lack of real-time, non-intrusive monitoring of key vital signs such as heart rate and body movement among frontline employees makes it difficult to effectively prevent safety accidents caused by overwork or sudden illness, and it is also difficult to quickly locate trapped personnel after an accident. Third, safety early warning methods are singular and passive, mainly relying on fixed sensors or proactive reporting by personnel, lacking effective proactive intervention methods for the dynamic risks faced by mobile employees. In addition, fully functional dedicated intelligent protective terminals are often expensive, have poor wearing experience, and require different equipment for different industries, resulting in low adoption rates, complex management, and difficulty in achieving full, 24 / 7 safety coverage.

[0004] To address the aforementioned issues, we designed a low-cost, widely adopted smart bracelet and method that can deeply integrate with a central safety management platform. This approach focuses on solving systemic technical challenges in high-risk industries, such as unknowable personnel status, delayed risk warnings, poor adaptability to different work scenarios, and low emergency rescue efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intrinsically safe smart bracelet that works in conjunction with a security management platform and a method for comprehensive personnel protection, thus solving the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intrinsically safe smart bracelet method that collaborates with a security management platform, comprising: Intrinsically safe housing and wrist strap, meeting explosion-proof standards for hazardous environments; The core processing and communication unit, integrated within the intrinsically safe housing, includes a main control chip, a positioning module, and a communication module. The positioning module includes an ultra-wideband (UWB) chip and / or a Bluetooth angle of arrival (AOA) chip, used to achieve high-precision positioning indoors and underground. The communication module supports Bluetooth communication for data interaction with field aggregation nodes, thereby establishing a communication connection with the central safety management platform. A multi-parameter sensing unit, integrated within the intrinsically safe housing, is electrically connected to the core processing and communication unit, including a vital signs sensor for monitoring the user's vital signs and a proximity sensor for sensing the power frequency electric field. The interaction and alarm unit, integrated within the intrinsically safe housing, is electrically connected to the core processing and communication unit and includes a vibration motor, an SOS physical button, and a low-power display screen.

[0007] Preferably, the vital signs sensor includes an optical heart rate sensor and an accelerometer, used to monitor the user's heart rate data, body movement status, and determine whether a fall has occurred.

[0008] Preferably, the communication module is a Bluetooth 5.2 communication module.

[0009] Preferably, the method is executed collaboratively by the wristband and the central security management platform, and includes the following steps: The wristband continuously acquires the wearer's real-time location information through the positioning module and reports it to the central security management platform through the communication module, thereby achieving precise location and dynamic management of personnel across the entire area. The wristband continuously monitors the wearer's vital signs and the surrounding environmental electric field information through the multi-parameter sensing unit, and reports the information to the central safety management platform through the communication module. The central safety management platform comprehensively analyzes the received vital signs parameters, environmental electric field information and location information according to preset alarm thresholds or rules. When it determines that there is an abnormality, it sends an early warning command to the corresponding wristband. The wristband receives the warning command and sends a warning reminder to the wearer through the interaction and alarm unit.

[0010] Preferably, the "continuous monitoring of the wearer's vital signs and the surrounding environmental electric field information through the multi-parameter sensing unit" specifically includes: The vital signs sensor monitors the wearer's heart rate and acceleration data. Based on the acceleration data, determine whether the person is in a state of falling or in a state of prolonged stillness; The proximity sensor monitors the power frequency electric field strength of the environment in which the person is located.

[0011] Preferably, the method further includes an intelligent emergency rescue step: In response to the wearer's triggering operation of the SOS physical button, the wristband generates an SOS alarm signal containing the person's identity information, real-time precise location and real-time vital signs data, and uploads it to the central security management platform through the communication module; In response to the SOS alarm signal, the central safety management platform calculates the optimal evacuation route for personnel in the risk area based on the real-time location information of all online personnel and the platform's known risk source distribution information. The central safety management platform converts the optimal evacuation route into tactile navigation instructions and sends them to the wristbands of the corresponding personnel. The wristband receives the tactile navigation command and controls the vibration motor to perform sequential vibrations to guide the wearer to evacuate along the optimal evacuation path.

[0012] Preferably, the "controlling the vibration motor to perform sequential vibration" specifically means: using vibration sequences of different modes to represent different directions of travel, including a first vibration mode for indicating a left turn, a second vibration mode for indicating a right turn, and a third vibration mode for indicating a straight-ahead direction.

[0013] Preferably, the method further includes a cross-industry adaptive configuration step: The central safety management platform remotely configures different working modes and alarm thresholds for the corresponding wristbands according to the safety needs of different industries or different work areas. The wristband receives and applies configuration information issued by the central security management platform to adjust its monitoring, early warning, or interactive behavior. Beneficial effects

[0014] This invention provides an intrinsically safe smart bracelet and a comprehensive personnel protection method that works in conjunction with a safety management platform. By integrating UWB / Bluetooth AOA high-precision positioning with vital sign monitoring, this invention achieves, for the first time, comprehensive, all-personnel, and all-weather knowledge and control over the "location and status" of frontline workers in high-risk industries, elevating safety management from passive response to proactive early warning. Its unique three-level emergency response mechanism of "SOS one-click alarm - platform intelligent judgment - tactile sequence navigation" constructs an efficient internal and external linkage rescue lifeline in extreme environments with limited communication or poor visibility, greatly improving the efficiency of group evacuation and the chances of individual survival. At the same time, this invention creatively adopts the flexible design concept of "platform-defined functions," enabling a low-cost, intrinsically safe, standardized bracelet to flexibly adapt to the common and personalized safety needs of multiple industries such as mining, chemical, and power through software configuration. It successfully solves the problem of popularization caused by the cost and specialization of high-end intelligent equipment, achieving the ultimate goal of "hardware standardization, functional softwareization, and universal safety" with extremely high cost performance, providing enterprises with an unprecedented cross-industry integrated personnel safety solution.

[0019] In this embodiment, the vital signs sensor includes an optical heart rate sensor and an accelerometer, used to monitor the user's heart rate data, body movement status, and determine whether a fall has occurred.

[0020] In this embodiment, the communication module is further configured as a Bluetooth 5.2 communication module.

[0021] This embodiment is further configured such that the method is executed collaboratively by the wristband and the central security management platform, and includes the following steps: The wristband continuously acquires the wearer's real-time location information through the positioning module and reports it to the central security management platform through the communication module, thereby achieving precise location and dynamic management of personnel across the entire area. The wristband continuously monitors the wearer's vital signs and the surrounding environmental electric field information through the multi-parameter sensing unit, and reports the information to the central safety management platform through the communication module. The central safety management platform comprehensively analyzes the received vital signs parameters, environmental electric field information and location information according to preset alarm thresholds or rules. When it determines that there is an abnormality, it sends an early warning command to the corresponding wristband. The wristband receives the warning command and sends a warning reminder to the wearer through the interaction and alarm unit.

[0022] This embodiment is further configured such that "continuously monitoring the wearer's vital signs and the surrounding environmental electric field information through the multi-parameter sensing unit" specifically includes: The vital signs sensor monitors the wearer's heart rate and acceleration data. Based on the acceleration data, determine whether the person is in a state of falling or in a state of prolonged stillness; The proximity sensor monitors the power frequency electric field strength of the environment in which the person is located.

[0023] This embodiment further specifies that the method includes an intelligent emergency rescue step: In response to the wearer's triggering operation of the SOS physical button, the wristband generates an SOS alarm signal containing the person's identity information, real-time precise location and real-time vital signs data, and uploads it to the central security management platform through the communication module; In response to the SOS alarm signal, the central safety management platform calculates the optimal evacuation route for personnel in the risk area based on the real-time location information of all online personnel and the platform's known risk source distribution information. The central safety management platform converts the optimal evacuation route into tactile navigation instructions and sends them to the wristbands of the corresponding personnel. The wristband receives the tactile navigation command and controls the vibration motor to perform sequential vibrations to guide the wearer to evacuate along the optimal evacuation path.

[0024] In this embodiment, the "controlling the vibration motor to perform serialized vibration" specifically means: using vibration sequences of different modes to represent different directions of travel, including a first vibration mode for indicating left turn, a second vibration mode for indicating right turn, and a third vibration mode for indicating straight travel.

[0025] This embodiment further specifies that the method includes a cross-industry adaptive configuration step: The central safety management platform remotely configures different working modes and alarm thresholds for the corresponding wristbands according to the safety needs of different industries or different work areas. The wristband receives and applies configuration information issued by the central security management platform to adjust its monitoring, early warning, or interactive behavior.

[0026] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0027] Example: The intrinsically safe smart bracelet and all-area personnel protection method described in this invention were fully applied. In the early morning, miner Zhang San received and put on his smart bracelet at the mine entrance. The bracelet automatically connected to the explosion-proof mobile phone aggregation node underground via Bluetooth and received the mine-specific work mode configuration issued by the "Anyu" central safety management platform. This mode primarily utilizes high-precision positioning, heart rate monitoring, fall detection, and proximity sensing functions. After descending into the mine, the bracelet's built-in UWB positioning module continuously worked, uploading Zhang San's real-time location information to the platform with centimeter-level accuracy, allowing safety administrators to clearly track his movement trajectory and work area on an electronic map. At 10:00 AM, while inspecting in the tunnel, Zhang San inadvertently approached a high-voltage distribution box. The bracelet's proximity sensor sensitively detected the enhanced power frequency electric field, immediately triggering a strong vibration as a warning. Simultaneously, the warning information and precise location were reported to the platform. The platform then generated a temporary electronic fence in the area and pushed warnings to the bracelets of other nearby personnel, successfully preventing a potential electric shock accident. In the afternoon, due to continuous work, Zhang San's heart rate became abnormally high. The vital signs sensor on his wristband detected this change and, while providing a slight vibration alert locally, uploaded the data to the platform. The platform system, combining his location information with historical data, determined it to be a health risk caused by fatigue and immediately sent an intervention instruction to the team leader, requiring him to rest. Unfortunately, a partial roof collapse suddenly occurred in the area shortly afterward. Zhang San fell and became trapped during the retreat. He immediately pressed and held the SOS button on his wristband for 3 seconds to trigger the emergency alarm. The wristband instantly packaged and uploaded his identity information, precise location (with a positioning accuracy of up to 0.3 meters), "fall" status determined by the accelerometer, and real-time heart rate data. The platform responded within seconds, notifying the ground rescue team to rush to the scene with Zhang San's precise location information. Simultaneously, based on the real-time location of all personnel underground and the diffusion model of the roof collapse risk source, the platform dynamically calculated the optimal evacuation route for employees in the affected area and converted the route instructions (such as "turn left ahead" or "go straight for 50 meters") into specific vibration sequences and sent them to each employee's wristband. In the extremely low visibility smoke, Zhang San and his colleagues were able to evacuate to a safe area efficiently and orderly, relying solely on the tactile guidance of their wristbands (for example, two short vibrations indicating a left turn and a long vibration indicating going straight) without needing to look at a screen, greatly improving the success rate of emergency rescue. Throughout the process, the intrinsically safe design of the wristband ensured safe use in hazardous environments, while its low power consumption guaranteed continuous operation during prolonged accident handling. This embodiment fully demonstrates the invention's comprehensive, proactive safety protection capabilities, from daily risk warnings and health monitoring to accurate alarms and intelligent evacuation in emergency situations.
