Description

Technical Field

[0001] This invention relates to the field of engineering safety monitoring technology, and more specifically, to a high-altitude operation safety monitoring system and method. Background Technology

[0002] Working at heights is a core operational scenario in industries such as construction, power, and municipal engineering, characterized by complex working environments, numerous risk factors, and serious consequences of accidents. Currently, safety monitoring for working at heights faces the following key technological challenges: 1. The contradiction between portability and full-dimensional monitoring: Existing solutions fall into two categories. One is a monitoring system based on a fixed multi-sensor platform, which has comprehensive monitoring dimensions but is complex to deploy and cannot be adapted to outdoor mobile high-altitude operation scenarios. The other is a single-function smart bracelet or safety helmet, which is highly portable but has seriously insufficient monitoring dimensions and cannot cover all risk elements of "human-machine-environment-management".

[0003] 2. The contradiction between post-event alarm and pre-event prevention: More than 90% of the existing technologies are passive modes of "alarm after an anomaly occurs", without full-chain pre-event access control, and cannot eliminate the most common core violations in the industry such as working under the influence of alcohol, working without a license, and falsely attaching safety belts from the source.

[0004] 3. The contradiction between uniform standards and individual differences: Existing solutions all adopt industry-standard safety thresholds, completely ignoring individual differences in the physical condition, work experience, and environmental tolerance of different workers. This results in warnings that are either too lenient to provide protection or too strict to interfere with normal operations.

[0005] Among existing publicly available technologies, patent document CN120472642B discloses a high-altitude operation fall prevention monitoring system, which only provides cloud-based early warnings based on physiological, posture, and environmental data, lacking a portable wearable structure, effective safety belt suspension detection, and pre-job access control. Patent document CN115766761A discloses a smart bracelet with a safety rope lock, which can only monitor heart rate and buckle status, lacking multi-dimensional linkage and closed-loop control. Therefore, existing high-altitude operation safety monitoring devices cannot effectively monitor workers and the working environment, thus failing to provide timely risk warnings and effectively prevent high-altitude operation safety accidents. Summary of the Invention

[0006] In view of this, the present invention proposes a high-altitude operation safety monitoring system, aiming to solve the problem that existing high-altitude operation safety monitoring devices cannot effectively prevent high-altitude operation safety accidents. The present invention also proposes a high-altitude operation safety monitoring method.

[0007] In one aspect, the present invention proposes a high-altitude operation safety monitoring system, which includes: a wearing device and a control platform; wherein, the wearing device is worn by the operator to detect the operator's physical parameter data and the operation parameter data of the operation; the control platform is electrically connected to the wearing device and is used to assess the operation risk based on the physical parameter data and the operation parameter data, determine the risk level, and send an alarm signal to the wearing device according to the risk level, while simultaneously triggering its own alarm; the wearing device is also used to trigger an alarm based on the alarm signal.

[0008] Furthermore, in the aforementioned high-altitude operation safety monitoring system, the wearable device includes: a wearable main body, a parameter monitoring unit, and a control unit, an alarm unit, and a communication unit disposed within the wearable main body; wherein, the wearable main body is worn by the operator; the parameter monitoring unit is used to monitor body parameter data and operation parameter data; the control unit is electrically connected to both the parameter monitoring unit and the alarm unit, and the control unit is also electrically connected to the control platform via the communication unit, used to send the body parameter data and operation parameter data sent by the parameter monitoring unit to the control platform, receive alarm signals sent by the control platform, and control the alarm unit to sound an alarm based on the alarm signals.

[0009] Furthermore, in the aforementioned high-altitude operation safety monitoring system, the parameter monitoring unit includes: a safety belt monitoring module installed in the safety belt, a physiological parameter monitoring module installed in the wearable body, an alcohol monitoring module, a positioning and height monitoring module, a visual monitoring module, an environmental monitoring module, a wearing monitoring module, and a communication status monitoring module; wherein, the safety belt monitoring module is used to monitor the condition of the safety belt; the physiological parameter monitoring module is used to monitor the worker's heart rate, blood oxygen, blood pressure, and mental stress level; the alcohol monitoring module is used to monitor the worker's blood alcohol concentration; the positioning and height monitoring module is used to monitor the worker's position and working height; the visual monitoring module is used to monitor the worker's working condition image; the environmental monitoring module is used to monitor the temperature, humidity, air pressure, and vibration data of the working environment; the wearing monitoring module is used to monitor whether the worker is wearing the wearable body correctly; and the communication status monitoring module is used to monitor the signal quality of the communication unit.

[0010] Furthermore, in the aforementioned high-altitude operation safety monitoring system, the control platform includes: a safety access analysis unit, a dynamic risk assessment unit, and a coupled early warning unit. The safety access analysis unit is electrically connected to the control unit and is used to detect whether a worker is qualified to perform the operation based on physical and operational parameter data. The dynamic risk assessment unit is electrically connected to the safety access analysis unit and is used to assess the operational risks based on physical and operational parameter data during the worker's operation. The coupled early warning unit is electrically connected to both the dynamic risk assessment unit and the control unit, and is used to determine the risk level based on the dynamic risk assessment unit's risk assessment results, and send corresponding alarm signals to the control unit according to the risk level. The coupled early warning unit is also electrically connected to the user terminal to send alarm signals corresponding to the risk level to the user terminal.

[0011] Furthermore, in the aforementioned high-altitude operation safety monitoring system, the safety access analysis unit is used to generate an individual safety baseline for the current operation based on physical parameter data and operation parameter data, combined with historical data. Based on the individual safety baseline for the current operation, the unit sequentially verifies the pre-job safety examination, educational qualifications, physical health, alcohol content, and whether the safety belt is properly worn by the operator. After all verifications are passed, the operator is deemed qualified to work.

[0012] Furthermore, in the aforementioned high-altitude operation safety monitoring system, the control platform also includes: a group interlock management unit and a risk warning unit; wherein, there are at least two wearing devices; the group interlock management unit is electrically connected to the control unit in each wearing device, and is used to receive body parameter data and operation parameter data sent by each control unit, and process the body parameter data and operation parameter data sent by each control unit on the same working surface to determine the hazard level; the risk warning unit is electrically connected to the group interlock management unit and each control unit, and is used to send a warning signal corresponding to the hazard level to the corresponding control unit according to the hazard level determined by the group interlock management unit. In addition, the risk warning unit is also used to be electrically connected to the user terminal to send the warning signal corresponding to the hazard level to the user terminal.

[0013] Furthermore, in the aforementioned high-altitude operation safety monitoring system, the control unit is also used to detect whether the operator can work based on body parameter data and operation parameter data when the communication unit cannot work normally, and to assess the operation risk and determine the risk level based on the body parameter data and operation parameter data during the operator's operation, and to control the alarm unit to sound an alarm based on the risk level; the control unit is also used to resend the data from when the communication unit could not work normally to the management and control platform when the communication unit resumes normal operation.

[0014] In this invention, a wearable device is worn by the worker to detect the worker's physical parameters and operational parameters. The wearable device sends the detected physical and operational parameters to a control platform. The control platform assesses the operational risks, determines the risk level, and sends an alarm signal to the wearable device based on the risk level, while simultaneously triggering its own alarm. This effectively enables comprehensive monitoring of the worker and operational conditions, and timely alarms for operational risks based on the physical and operational parameters, thereby effectively preventing high-altitude work safety accidents and solving the problem that existing high-altitude work safety monitoring devices cannot effectively prevent high-altitude work safety accidents.

[0015] On the other hand, the present invention also proposes a method for monitoring safety during high-altitude operations, which includes the following steps: a self-inspection step, in which the worker wears the device and performs a self-inspection; a detection step, in which, after the self-inspection of the device is qualified, the worker is tested to see if he / she can work, and after confirming that the worker can work, the device is worn to enter the work mode; a risk level determination step, in which the worker's physical parameter data and the work condition parameter data are collected, and the work risk is assessed based on the physical parameter data and the work parameter data to determine the risk level; and an alarm step, in which an alarm is triggered on the worker based on the determined risk level.

[0016] Furthermore, in the above-mentioned high-altitude operation safety monitoring method, the detection step involves collecting the physical parameter data of the operator and the operation parameter data of the working condition. Based on the physical parameter data and operation parameter data combined with historical data, an individual safety baseline for this operation is generated. Based on the individual safety baseline for this operation, the operator is sequentially verified for pre-job safety examination, educational qualifications, physical health, alcohol content, and proper use of safety belts. After all verifications are passed, the operator is confirmed to be able to work.

[0017] Furthermore, in the above-mentioned high-altitude operation safety monitoring method, after the alarm step, the method further includes: when multiple workers wearing devices are placed on the same working surface, collecting the body parameter data of each worker on the same working surface and the operation parameter data of each worker under the working conditions, processing the body parameter data and operation parameter data, determining the danger level, and issuing an early warning to the corresponding worker based on the determined danger level.

[0018] In this invention, the device is worn by the worker for self-check, and then the device checks whether the worker is ready to work. After confirming that the worker is ready to work, the device collects the worker's physical parameters and the work parameters of the work situation. Based on the physical parameters and the work parameters, the device assesses the work risk, determines the risk level, and issues an alarm to the worker based on the determined risk level. In this way, the device can effectively monitor the worker and the work situation comprehensively, and can promptly issue alarms for work risks based on the physical parameters and the work parameters, thereby effectively preventing high-altitude work safety accidents.

Detailed Implementation

[0020] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example of a high-altitude work safety monitoring system: See Figure 1 , Figure 1This is a structural block diagram of a high-altitude work safety monitoring system provided in an embodiment of the present invention. As shown in the figure, the high-altitude work safety monitoring system includes: a wearing device 100 and a control platform 200. The wearing device 100 is worn by the worker and is used to detect the worker's physical parameters and work-related parameters. The physical parameters may include: the worker's heart rate, blood oxygen saturation, blood pressure, mental stress level, and alcohol concentration. The work-related parameters may include: the worker's position, working height, on-site video data, environmental information, safety belt status information, and whether the safety belt is worn correctly.

[0022] The control platform 200 is electrically connected to the wearable device 100. The control platform 200 receives body parameter data and work parameter data sent by the wearable device 100, assesses the work risk based on this data, determines the risk level, and sends an alarm signal to the wearable device 100 according to the risk level. The wearable device 100 also receives the alarm signal and triggers an alarm accordingly. Furthermore, the control platform 200 also triggers its own alarm based on the risk level.

[0023] As can be seen, in this embodiment, the wearable device 100 is worn by the worker to detect the worker's physical parameters and the work parameters of the work situation. The wearable device 100 sends the detected physical parameters and work parameters to the control platform 200. The control platform 200 assesses the work risk, determines the risk level, and sends an alarm signal to the wearable device 100 based on the risk level, while also triggering its own alarm. In this way, the worker and the work situation can be effectively monitored comprehensively, and the work risk can be promptly alarmed based on the physical parameters and work parameters, thereby effectively preventing high-altitude work safety accidents and solving the problem that existing high-altitude work safety monitoring devices cannot effectively prevent high-altitude work safety accidents.

[0024] See Figure 2 In the above embodiments, the wearing device 100 includes: a wearable main body, a parameter monitoring unit 110, a control unit 120, an alarm unit 130, and a communication unit 140. The wearable main body is worn by the worker; specifically, it can be a wristband, safety helmet, etc., and this embodiment does not impose any limitations on this.

[0025] In practical implementation, the wearable main body adopts an industrial-grade sports wristband structure design, the shell meets the IP68 waterproof and dustproof standard, the working temperature range is -35℃~75℃, and it has passed the MIL-STD-810G military standard impact resistance test, making it suitable for complex and harsh working scenarios such as construction, power, and field.

[0026] The parameter monitoring unit 110 is used to monitor the physical parameter data of the operator and the operation parameter data of the working conditions.

[0027] The control unit 120, alarm unit 130, and communication unit 140 are all housed inside the wearable main body. The control unit 120 is electrically connected to both the parameter monitoring unit 110 and the alarm unit 130. Furthermore, the control unit 120 is electrically connected to the management platform 200 via the communication unit 140. The control unit 120 receives body parameter data and work parameter data detected by the parameter monitoring unit 110 and transmits this data to the management platform 200. The control unit 120 also receives alarm signals from the management platform 200 and controls the alarm unit 130 to activate the alarm based on these signals. Specifically, the control unit 120 employs a low-power edge computing main control chip. The control unit 120 sends the alarm signal to the alarm unit 130, which receives the alarm signal and activates the alarm accordingly. The control unit 120 also features local function interlocking and remote access control.

[0028] The communication unit 140 supports multiple communication methods including 4G / 5G mobile communication, Wi-Fi, Bluetooth, and LoRa, and can automatically switch to the optimal communication mode according to the working environment; it also supports LoRa self-organizing network in the absence of a public network, enabling collaborative communication among multiple devices within the work area.

[0029] The alarm unit 130 may include: a vibration motor, an audible and visual alarm, and a real-time voice prompt unit, supporting tiered early warning and voice intervention.

[0030] Preferably, the wearable device 100 further includes a power management unit. The power management unit can be a high-capacity, low-power lithium battery, supporting fast charging and long battery life, to power the wearable device 100, and also supports automatic switching to low-power modes.

[0031] Preferred, see Figure 3The parameter monitoring unit 110 includes: a seat belt monitoring module 111, a physiological parameter monitoring module 112, an alcohol monitoring module 113, a positioning and altitude monitoring module 114, a visual monitoring module 115, an environmental monitoring module 116, a wearing monitoring module 117, and a communication status monitoring module 118. The seat belt monitoring module 111 is mounted on the seat belt and is used to monitor the condition of the seat belt. Specifically, the seat belt monitoring module 111 includes: a magnetic induction sensor, an abutment point tension sensor, and an attitude tilt sensor to verify the effective attachment of the seat belt. The magnetic induction sensor monitors whether the seat belt buckle is engaged, the abutment point tension sensor is installed at the anchor end of the seat belt abutment point to detect the static tension value of the abutment point in real time, and the attitude tilt sensor monitors the tilt angle of the human body. In this way, the condition of the safety belt is monitored by magnetic induction sensor, tension sensor at the attachment point, and attitude tilt sensor, thereby determining whether the safety belt is truly attached or falsely attached. This prevents the phenomenon of "only measuring the buckle engagement but not the effective suspension", effectively eliminating the problem of false attachment of the safety belt, and thus enabling safety monitoring of high-altitude operations.

[0032] In practical implementation, an example is given to illustrate the effective verification of seat belt attachment, as follows: Table 1 is a schematic diagram of the logic for verifying the validity of seat belt attachment. The physiological parameter monitoring module 112, alcohol monitoring module 113, positioning and altitude monitoring module 114, visual monitoring module 115, environmental monitoring module 116, wearable monitoring module 117, and communication status monitoring module 118 are all located inside the wearable main body. The physiological parameter monitoring module 112 is used to monitor the worker's heart rate, blood oxygen, blood pressure, and mental stress level. Specifically, the physiological parameter monitoring module 112 may include: a reflective photoelectric sensor for monitoring the worker's heart rate and blood oxygen, an oscillometric blood pressure monitoring sensor for monitoring the worker's blood pressure, and a skin conductance sensor for monitoring the worker's mental stress level, so as to collect the worker's heart rate, blood oxygen, blood pressure, and mental stress level data in real time.

[0033] The alcohol monitoring module 113 is used to monitor the alcohol concentration of workers. Specifically, the alcohol monitoring module 113 can use an electrochemical alcohol sensor, supporting both contact and non-contact methods, to monitor the alcohol concentration in the workers' exhaled breath. The alcohol monitoring module 113 supports three modes: mandatory pre-job testing, random sampling during work, and retesting triggered by abnormalities.

[0034] The positioning and height monitoring module 114 is used to monitor the position and working height of the operator. Specifically, the positioning and height monitoring module 114 may include a GPS / BeiDou dual-mode positioning module and a barometric altimeter. The GPS / BeiDou dual-mode positioning module is used to monitor the precise position of the operator, and the barometric altimeter is used to monitor the operator's working height, so as to realize the determination of electronic fence boundary crossing.

[0035] The visual monitoring module 115 is used to monitor the working conditions of the workers. Specifically, the visual monitoring module 115 can be a built-in miniature wide-angle camera for on-site video monitoring, remote evidence collection, and visual verification of hazardous behaviors.

[0036] The environmental monitoring module 116 is used to monitor the temperature, humidity, air pressure, and vibration data of the working environment. Specifically, the environmental monitoring module 116 may include a temperature sensor, a humidity sensor, an air pressure sensor, and a vibration sensor to collect real-time data on changes in temperature, humidity, air pressure, and vibration of the working platform, while simultaneously achieving automatic calibration of sensor accuracy.

[0037] The wearability monitoring module 117 is used to monitor whether the operator is wearing the wearable device correctly. In practice, if the device is not worn correctly, the control unit 120 automatically shuts down unnecessary functions to reduce power consumption.

[0038] The communication status monitoring module 118 is used to monitor the signal quality of the communication unit 140. Specifically, the communication status monitoring module 118 monitors the signal quality of 4G / 5G, Wi-Fi, Bluetooth, and LoRa communication in real time and automatically switches to the optimal communication mode.

[0039] See Figure 4 The control platform 200 includes a safety access analysis unit 210, a dynamic risk assessment unit 220, and a coupling early warning unit 230. The safety access analysis unit 210 is electrically connected to the control unit 120 via a communication unit 140 in the wearable device 100. The safety access analysis unit 210 receives body parameter data and work parameter data sent by the control unit 120, and determines whether the worker is qualified to work based on the body parameter data and work parameter data.

[0040] Specifically, the safety access analysis unit 210 generates an individual safety baseline for the current operation based on physical and operational parameter data, combined with historical data. Based on this baseline, the operator undergoes a pre-job safety examination, verification of educational qualifications, physical health, alcohol levels, and proper use of safety belts. Once all verifications are passed, the operator is deemed fit to work, and the device 100 is activated to enter work mode. More specifically, mandatory verifications are performed in a fixed order: "passing the pre-job safety examination → verifying the third-level educational qualifications → meeting physical health standards → passing the alcohol test → verifying proper use of safety belts." This order cannot be reversed or bypassed. Only after all five verifications are passed is the operator deemed fit to work. In this way, by using the individual safety baseline for the current operation to conduct pre-job testing, the operator's suitability for the operation can be accurately determined, thereby ensuring the safety of workers performing high-altitude work.

[0041] The dynamic risk assessment unit 220 is electrically connected to the safety access analysis unit 210. The dynamic risk assessment unit 220 assesses the operational risk based on physical and operational parameter data during the operator's work process, after determining that the operator is safe to work. Specifically, the dynamic risk assessment unit 220 performs secondary risk verification and dynamic threshold optimization in the cloud based on factors such as work height, environmental parameters, work duration, and fatigue index.

[0042] The coupling early warning unit 230 is electrically connected to both the dynamic risk assessment unit 220 and the control unit 120. The coupling early warning unit 230 receives the operational risk assessment results sent by the dynamic risk assessment unit 220, determines the risk level based on the assessment results, and then sends a corresponding alarm signal to the control unit 120 according to the risk level. The control unit 120 receives the alarm signal and controls the alarm unit 130 to activate the alarm accordingly. Specifically, the coupling early warning unit 230 is electrically connected to the control unit 120 via the communication unit 140.

[0043] The coupled early warning unit 230 performs coupled calculations based on four-dimensional data coupling of physiological state, behavioral posture, equipment status, and working environment to achieve accurate risk early warning and hierarchical push of alarm signals corresponding to risk levels.

[0044] The coupling early warning unit 230 is also electrically connected to a user terminal to send alarm signals corresponding to the risk level to the user terminal. Specifically, the user terminal can be a mobile phone, tablet, etc. The coupling early warning unit 230 sends alarm signals to the user terminal, and managers can learn about operational risks through the user terminal.

[0045] See Figure 4There can be at least two wearing devices 100. The control platform 200 also includes a group interlock management unit 240 and a risk warning unit 250. The group interlock management unit 240 is electrically connected to the control unit 120 in each wearing device 100 via the communication unit 140 in each wearing device 100. The group interlock management unit 240 receives body parameter data and work parameter data sent by each control unit 120, processes the body parameter data and work parameter data sent by each control unit 120 on the same work surface, and determines the hazard level. The group interlock management unit 240 realizes multi-device collaborative control at the work surface level and achieves full-scale early warning for single-person anomalies.

[0046] The risk warning unit 250 is electrically connected to the group interlock management unit 240 and each control unit 120. The risk warning unit 250 is used to send a warning signal corresponding to the danger level determined by the group interlock management unit 240 to the corresponding control unit 120. The corresponding control unit 120 is used to receive the warning signal and control the alarm unit 130 to sound an alarm based on the warning signal.

[0047] The risk warning unit 250 is also used to electrically connect to the user terminal to send a warning signal corresponding to the danger level to the user terminal.

[0048] As can be seen, in this embodiment, the group interlock management unit 240 can monitor and process the work status of multiple workers on the same work surface, thereby determining the hazard level. Based on the hazard level, graded warnings are issued to both workers and managers, so that workers and managers can take corresponding actions according to the graded warnings. In specific implementation, the risk warning unit 250 supports remotely issuing commands to lock the wearing device 100 and disable work permissions.

[0049] Preferably, the control platform 200 further includes a data receiving and storage unit. This data receiving and storage unit receives and stores comprehensive monitoring data, operation records, and abnormal event data uploaded by the control unit 120 in the encrypted wearable device 100, supporting full lifecycle traceability of the data.

[0050] Preferably, the management platform 200 also includes a full lifecycle safety file unit. This unit establishes a unique full lifecycle safety digital file for each worker, including health data, violation records, work hours, skill qualifications, three-level training records, and accident history.

[0051] Preferably, the management platform 200 is also electrically connected to the smart construction site docking unit to seamlessly connect with the smart construction site system, realize the real-name binding of workers, synchronize the three-level education records, automatically archive violation information, and dynamically manage the qualifications of workers.

[0052] Preferably, the control unit 120 is also used to detect whether the worker can work based on body parameter data and work parameter data when the communication unit 140 is not working properly, and to assess the work risk and determine the risk level based on the body parameter data and work parameter data during the worker's work, and to control the alarm unit 130 to sound an alarm based on the risk level. The control unit 120 is also used to resend all data from when the communication unit 140 was not working properly to the management platform 200 when the communication unit 140 resumes normal operation. In this way, when the wearable device 100 cannot connect to the management platform 200, the control unit 120 can continue to operate, thereby assessing the work risk and sounding an alarm, effectively preventing high-altitude work safety accidents. Specifically, the control unit 120 incorporates two core algorithm models: an individual baseline adaptive dynamic threshold model and a risk-progressive multi-sensor linkage decision model. The individual baseline adaptive dynamic threshold model is used to detect whether the worker can work based on body parameter data and work parameter data, and the risk-progressive multi-sensor linkage decision model is used to assess the work risk and determine the risk level based on body parameter data and work parameter data. Through the individual baseline adaptive dynamic threshold model and the risk-progressive multi-sensor linkage decision-making model, the system completes full-dimensional data acquisition, preprocessing, coupled calculation, risk assessment, and command output. All core calculations are completed in the control unit 120, without relying on the management platform 200.

[0053] In summary, in this embodiment, the wearable device 100 sends the detected body parameter data and work parameter data to the control platform 200. The control platform 200 assesses the work risk, determines the risk level, and sends an alarm signal to the wearable device 100 based on the risk level, while also triggering its own alarm. This effectively enables comprehensive monitoring of workers and work conditions, and timely alarms for work risks based on body parameter data and work parameter data, thereby effectively preventing high-altitude work safety accidents.

[0054] In this embodiment, the risk level of the operation is assessed and determined based on real-time collected body parameter data and operation parameter data, eliminating the need for fixed thresholds and reducing false alarm rates. Furthermore, the control platform 200 directly assesses and determines the risk level, sending corresponding alarm information to the control unit 120 to trigger an alarm, shortening alarm time and improving real-time performance. The system achieves a closed-loop control chain from pre-job qualification verification to data archiving at the end of the operation, realizing inherent safety control from the source. Through multi-dimensional data cross-verification, the system reduces the early warning rate and ensures the real-time nature of risk identification. It also enables multi-device collaborative control in the absence of a public network via LoRa self-organizing network, upgrading from individual safety protection to group operation joint prevention. The system does not completely rely on the control platform 200 and the public network; the control unit 120 of the wearable device 100 can also detect pre-job workers and assess and determine risk levels during the operation, achieving full-scene safety coverage. This system achieves a complete closed loop of "monitoring-early warning-control-traceability-management," deeply adapting to the needs of smart construction site construction. Furthermore, the wearable device is ready to use immediately upon wearing, requires no wiring, and has extremely low deployment costs. At the same time, it achieves comprehensive risk monitoring, taking into account both portability and comprehensiveness.

[0055] Example of a method for monitoring safety during high-altitude operations: This embodiment also proposes a method for monitoring the safety of high-altitude operations using any of the above-mentioned high-altitude operation safety monitoring systems. The specific implementation process of the high-altitude operation safety monitoring system is described above and will not be repeated here. See also Figure 5 The method for monitoring the safety of high-altitude operations includes the following steps: Self-inspection step S1: After the device is worn by the operator, a self-inspection is performed.

[0056] Specifically, after the operator puts on the device, the device is turned on and performs a comprehensive self-test of each unit within the device. If the self-test fails, the device is locked and a fault message is displayed.

[0057] In step S2, after the device passes the self-test, the device checks whether the operator is qualified to work. After confirming that the operator is qualified to work, the device is put into operation mode.

[0058] Specifically, after the device passes self-test, it automatically collects the worker's physical parameters and work parameters in real time. The control platform generates an individual safety baseline for the current operation based on the physical parameters and work parameters, combined with historical data. Based on the individual safety baseline, the platform sequentially verifies the worker's pre-job safety examination, educational qualifications, physical health, alcohol level, and whether the safety belt is properly worn. After all verifications are passed, the worker is confirmed to be ready to work.

[0059] More specifically, the device collects vital physical parameters of the worker at rest, such as heart rate, blood pressure, and baseline skin conductance, and then sends this data to the control platform. The safety access analysis unit on the control platform generates an individual safety baseline for the current operation based on the vital physical parameters, historical operational data, and the worker's full lifecycle safety record. Based on this individual safety baseline and the collected vital physical and operational parameters, the worker sequentially passes five verification tests. If any test is failed, the device is locked, preventing entry into the operational mode. The five verification tests are as follows: 1. Pre-job safety examination pass verification: Pass the pre-job safety examination on the same day; 2. On-the-job qualification verification: The Level 3 education certificate is valid and the job qualification matches the current job type; 3. Physiological health standard verification: Heart rate, blood pressure, and tension level are within the normal fluctuation range of the individual baseline; 4. Alcohol test pass verification: Breath alcohol concentration ≤ 0.2mg / L; 5. Seatbelt proper attachment verification: The seatbelt buckle is properly engaged, the static tension at the attachment point is stable in the range of 5-50kg, and the body posture angle is <15°, all three conditions must be met simultaneously. After passing all five verification tests, the device is worn and the work mode is entered.

[0060] Step S3 for determining the risk level involves collecting physical parameter data of the workers and operational parameter data of the work conditions, and assessing the operational risks based on the physical parameter data and operational parameter data to determine the risk level.

[0061] Specifically, during the operation, the wearable device collects real-time data on physiological, posture, safety belt, environment, positioning, and vision data. The dynamic risk assessment unit assesses the operational risks in real time based on the individual baseline and the progressive multi-sensor linkage decision-making model, while the coupled early warning unit calculates the comprehensive risk level in real time.

[0062] Alarm step S4: Alarm is triggered on the workers based on the determined risk level.

[0063] Specifically, the coupled early warning unit executes corresponding tiered control measures based on the risk level. An example of tiered alarms based on risk level is as follows: Level 1 (Prompt Level): Mild anomaly in a single dimension, with no risk of linkage in other dimensions. The wearable device will vibrate slightly and give a gentle voice prompt. No notification will be sent to administrators, and no violation will be recorded.

[0064] Level 2 (early warning level): Anomalies occur in two dimensions. Risk is confirmed through cross-verification. An audible and visual alarm is triggered, and the team leader is notified. A voice prompt is given to stop the operation and conduct an inspection. The abnormal event is recorded.

[0065] Level 3 (locked-up level): If three or more dimensions are abnormal, or the core safety item fails, execute local function lock + high-decibel emergency alarm + synchronous push to project manager + activate emergency response, and forcibly prohibit continued operation while wearing the device.

[0066] In practice, when there is no public network signal in the work environment, the wearable device automatically switches to offline operation mode, and all core functions (data acquisition, assessment and analysis, risk judgment, graded early warning, and interlocking control) operate normally. After the public network signal is restored, all data during the offline period is automatically transmitted to the management and control platform to ensure data traceability.

[0067] After the operation is completed, all data is automatically archived to the management platform, and the full lifecycle safety digital profiles of the operators are updated synchronously. The profile data is used for self-learning optimization of individual baseline models, while providing data-driven decision support for enterprise safety management, forming a complete safety management closed loop.

[0068] As can be seen, in this embodiment, the device is worn by the worker for self-check, and then the device checks whether the worker is capable of working. After confirming that the worker is capable of working, the device collects the worker's physical parameters and the work parameters of the work situation, and assesses the work risk based on the physical parameters and the work parameters to determine the risk level. Based on the determined risk level, the device alerts the worker. In this way, the device can effectively monitor the worker and the work situation comprehensively, and can promptly alert the worker to work risks based on the physical parameters and the work parameters, thereby effectively preventing high-altitude work safety accidents.

[0069] See Figure 6 The method for monitoring the safety of high-altitude operations includes the following steps: Self-inspection step S1: After the device is worn by the operator, a self-inspection is performed.

[0070] In step S2, after the device passes the self-test, the device checks whether the operator is qualified to work. After confirming that the operator is qualified to work, the device is put into operation mode.

[0071] Step S3 for determining the risk level involves collecting physical parameter data of the workers and operational parameter data of the work conditions, and assessing the operational risks based on the physical parameter data and operational parameter data to determine the risk level.

[0072] Alarm step S4: Alarm is triggered on the workers based on the determined risk level.

[0073] Step S5: When multiple workers wearing the device are placed on the same work surface, collect the body parameter data of each worker on the same work surface and the work parameter data of each worker under the working conditions, process the body parameter data and work parameter data, determine the hazard level, and issue a warning to the corresponding worker based on the determined hazard level.

[0074] Specifically, multiple wearable devices on the same work surface can achieve group-based joint defense through a LoRa self-organizing network, for example: (1) If any person triggers the third-level alarm in the above alarm step S4, all wearing devices on the same work surface will issue a warning simultaneously to remind the surrounding personnel to take shelter.

[0075] (2) If any person crosses the boundary and enters the danger zone, all wearing devices on the same work surface will trigger a strong alarm first. If there is no response within 10 seconds, the alarm level will be automatically upgraded.

[0076] (3) The overall parameters of the working environment exceed the standard, and all wearable devices are downgraded in working authority and prompted to leave the working area.

[0077] As can be seen, in this embodiment, by processing the physical parameter data of each worker on the same working surface and the operational parameter data of each worker under the working conditions, the danger level is determined, and then the corresponding worker is given an early warning based on the determined danger level, so that the workers and managers can take corresponding actions according to the graded early warning, effectively ensuring the safety of high-altitude operations and thus effectively preventing high-altitude operation safety accidents.

[0078] Taking the scenario of high-altitude operations on the exterior walls of a construction site as an example, this paper introduces the methods for safety monitoring of high-altitude operations: 1. Device distribution and binding: Distribute and bind the device to the workers working on the exterior walls, and complete the real-name binding of the personnel through the management platform, and synchronize their high-altitude operation qualifications, level 3 safety education certificate, and historical safety operation records into the full life cycle safety digital file.

[0079] 2. Device Start-up and Self-Test: After the operator puts on the device, the device will automatically turn on and complete a comprehensive self-test of the parameter monitoring unit, control unit, alarm unit and communication unit. After the self-test is passed, the pre-job calibration process will begin.

[0080] 3. Dynamic calibration of individual baselines: The operator remains at rest on the ground and wears a device to automatically collect his resting heart rate of 75 beats / minute, blood pressure of 120 / 80 mmHg, and skin conductance response of 12 μS. Combined with his historical work data, an individual safety baseline for this operation is generated.

[0081] 4. Mandatory Verification for On-the-Job Entry: Workers must complete five mandatory checks in sequence: ① Pass the daily pre-job safety exam with a perfect score on all five questions; ② Verify that the Level 3 safety training certificate is valid and that the worker's high-altitude work qualifications match the requirements; ③ Ensure physiological data are within the normal fluctuation range of the baseline; ④ Verify that the alcohol concentration is 0 mg / L; ⑤ Verify that the safety belt attachment point tension is stable at 12 kg, the buckle is properly engaged, and the tilt angle is 8°, thus passing the actual attachment verification. After all checks are completed, the worker wearing the safety harness will be unlocked and allowed to enter the work basket.

[0082] 5. Real-time monitoring during operation: When the operator ascends to an operating height of 18m in the suspended platform, the device automatically tightens the warning threshold by 15%, and collects the operator's physiological data, posture data, safety belt status, suspended platform vibration, ambient temperature and humidity, and positioning data in real time to calculate the risk level. When the device communicates normally with the control platform, the control platform calculates the risk level; when the device and the control platform cannot communicate normally, the control unit in the device calculates the risk level.

[0083] 6. Tiered Early Warning and Proactive Intervention: During operation, if the operator continues to lean forward, with a tilt angle reaching 32°, and the suspended platform vibrates to 0.7g due to wind, the device will trigger a Level 2 Orange warning, with an audible and visual alarm and a voice prompt saying "Dangerous posture, please maintain your balance," and will also send a notification to the on-site safety officer. If the operator unfastens their safety belt, and the device detects no anchor point tension and an operating height of 18m, it will directly trigger a Level 3 Red interlock, with a high-decibel emergency alarm and locking of the safety device, and will simultaneously send a notification to the project manager and safety director.

[0084] 7. Offline Operation Guarantee: During operation, if the main building blocks the signal and there is no 4G / 5G signal, the wearable device will automatically switch to offline operation mode, and all monitoring, early warning and locking functions will operate normally. After the suspended platform descends to an area with good ground signal, the wearable device will automatically transmit all operation data during the offline period to the management platform.

[0085] 8. Closed-loop management upon completion of work: After the work is completed for the day, the wearable device automatically uploads all work data to the management platform, updates the safety files of the workers, records the duration of the work and any violations, and optimizes the self-learning parameters of the individual baseline model to complete the closed-loop safety management of the entire work process.

[0086] In summary, this embodiment can effectively monitor the workers and working conditions comprehensively, and can promptly issue alarms for operational risks based on physical and operational parameter data, thereby effectively preventing high-altitude work safety accidents.
