Description

A safety management system based on smart helmets Technical Field

[0001] This invention relates to the field of smart helmet technology, and more specifically, to a safety management system based on smart helmets. Background Technology

[0002] Existing on-site safety management systems mostly employ a combination of manual attendance tracking, fixed monitoring equipment, and independent safety protective gear. Typically, workers must complete attendance records before entering the construction or work area via card swiping, fingerprint recognition, or manual sign-in. On-site safety supervision primarily relies on fixed cameras, access control systems, or manual patrols to determine whether personnel have entered designated areas. Safety helmets and other protective equipment are used only as passive protection, and their correct wearing is usually confirmed through visual inspection by on-site management personnel or subsequent spot checks. While some systems incorporate positioning terminals or wearable devices, they are mostly single-function, such as simply uploading location data or providing basic alarms; related data must be viewed and managed through a separate platform.

[0003] However, the aforementioned existing technologies still have many shortcomings in practical applications. On the one hand, manual attendance and inspection methods rely on human operation, which is inefficient and prone to problems such as missed inspections and misjudgments, making it difficult to achieve real-time and continuous safety supervision. On the other hand, there is a lack of effective linkage between protective equipment and the safety management system, making it impossible to promptly detect and proactively warn of behaviors such as removing hats or leaving posts without permission, posing significant safety hazards. In addition, location data, attendance data, and environmental data in existing systems are often stored separately on different platforms, resulting in severe data isolation, which is not conducive to unified management and comprehensive analysis, and makes it difficult to provide effective data support for safety management decisions. The overall level of intelligence and management precision needs to be further improved. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a safety management system based on a smart safety helmet, which solves the problems mentioned in the background art through the following solutions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety management system based on an intelligent safety helmet, comprising:

[0006] The smart safety helmet terminal, electronic fence module, cloud data center, and mobile management terminal interact and work collaboratively through Internet of Things (IoT) communication.

The GPS / BeiDou dual-mode positioning unit is used for positioning in outdoor work scenarios, and the UWB indoor positioning unit is used for high-precision indoor positioning.

[0014] Preferably, the IoT communication module uses 4G, 5G or NB-IoT wireless communication technology to upload location data, wearing status data and alarm information to the cloud data center, and to receive configuration parameters sent from the cloud.

[0015] Preferably, the human body sensor is disposed in the inner lining of the safety helmet to detect the wearing status of the safety helmet, and the human body sensor is any one or more combinations of a thin-film pressure sensor, an infrared sensor, or a capacitive sensor.

[0016] Preferably, the local alarm includes a buzzer and / or a vibration motor, used to provide audible or vibration alerts to the wearer when hat removal or abnormal conditions beyond the electronic fence are detected.

[0017] Preferably, the environmental sensor includes a temperature and humidity sensor, used to collect safety parameters of the working environment and upload them to a cloud data center.

[0018] Preferably, the electronic fence module is a virtual electronic fence or a physical fence set based on location data, and its boundary information is drawn and configured by the administrator on the electronic map of the cloud data center.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. This invention achieves automatic sensing and real-time uploading of the location and wearing status of workers by coordinating the design of smart safety helmet terminals with electronic fences and cloud data centers. This avoids reliance on manual operations such as manual check-in and manual inspection. The system can automatically complete attendance determination when personnel enter or leave the designated work area and trigger reminders in time when abnormal status occurs, thereby achieving continuous and real-time safety management and effectively improving the timeliness and reliability of on-site management.

[0022] 2. This invention upgrades the safety helmet from a traditional passive protective device to an intelligent terminal with sensing, judgment and execution capabilities. Through the cooperation of human body sensing sensors and positioning modules, it can actively identify the behavior of removing the helmet and leaving the post without permission, and process it through a combination of local alarm and cloud alarm, so as to form a linkage mechanism between the safety protection and management system, enhance the early warning capability of non-standard operation behavior, and reduce potential safety risks.

[0023] 3. In addition, this invention uses a cloud data center to uniformly store and analyze personnel location data, attendance information, alarm events and environmental parameters, avoiding the data isolation problem caused by the decentralized management of multiple systems, realizing centralized management and visualization of data, and providing managers with more intuitive and comprehensive safety management information support through the statistical analysis of historical data, which helps to improve the overall level of intelligence and scientific decision-making in safety management.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Referring to Figures 1-4, a safety management system based on a smart safety helmet includes: a smart safety helmet terminal 100, an electronic fence module 200, a cloud data center 300, and a mobile management terminal 400.

[0030] Among them, the smart safety helmet terminal 100 serves as the front-end sensing and execution unit, the electronic fence module 200 is used to define the rules of the work area, and the cloud data center 300 serves as the system back-end to realize data management and analysis. All modules work together through Internet of Things communication.

[0031] The smart safety helmet terminal 100 integrates the following functional modules: main controller 101, positioning module 102, Internet of Things communication module 103, human body induction sensor 104, local alarm 105, and environmental sensor 106.

[0032] The main controller 101 uses a low-power microprocessor to collect, process, and make logical judgments on data from various sensors, and to control alarm and communication behaviors. It is the core control unit of the smart safety helmet terminal 100.

[0033] The positioning module 102 is used to acquire the location information of the wearer in real time, specifically including: a GPS / BeiDou dual-mode positioning unit for outdoor operation scenarios; and a UWB indoor positioning unit for high-precision indoor positioning scenarios.

[0034] The IoT communication module 103 uses 4G, 5G or NB-IoT wireless communication technology to upload location data, wearing status data and alarm information to the cloud data center 300, and to receive configuration parameters sent from the cloud.

[0035] The human body sensor 104 is installed inside the helmet liner to detect the wearing status. The sensor can be a thin-film pressure sensor, an infrared sensor or a capacitive sensor, and can determine whether the helmet is worn correctly by detecting head contact or heat source signals.

[0036] The local alarm 105 includes a vibration motor or buzzer. When it detects abnormal conditions such as removing a hat or leaving the post without permission, it is used to immediately remind the wearer by sound or vibration. The acquired location data is used for attendance determination and electronic fence compliance detection.

[0037] The environmental sensor 106 includes a temperature and humidity sensor, used to collect safety parameters of the working environment and upload them to the cloud.

[0038] The electronic fence module 200 is used to define the legal activity area for workers, and it can take the form of a physical fence or a virtual electronic fence set based on positioning data.

[0039] The boundary information of the electronic fence is drawn and configured by the administrator on the electronic map of the cloud data center 300, and can be used to distinguish attendance areas, normal work areas and dangerous restricted areas.

[0040] The cloud data center 300 serves as the system's backend management unit and includes: a data storage unit and a data analysis and visualization unit.

[0041] The data storage unit is used to store personnel location information, attendance records, alarm events, and environmental data; the data analysis and visualization unit is used to perform statistical analysis on the collected data and display it in the form of charts, heat maps, and reports.

[0042] Managers can view personnel distribution, attendance status, and security alarm information in real time via PC or mobile management terminal.

[0043] The specific workflow of this embodiment is as follows:

[0044] Automatic attendance process: When a worker wearing a smart safety helmet terminal 100 enters the preset attendance electronic fence area, the positioning module 102 obtains the location information and transmits it to the main controller 101;

[0045] After the main controller 101 determines the location of a person and enters the attendance fence, it automatically uploads the "working" attendance record to the cloud data center 300 through the IoT communication module 103; when the person leaves the area, it automatically generates the "leaving" attendance record, realizing seamless and automated attendance.

[0046] Mid-term absence alarm process: During normal working hours, when the system detects that the operator's location has exceeded the range of the electronic fence of their assigned work area, the main controller 101 determines it as a suspected absence from the post.

[0047] The system can be set with a delayed confirmation time (e.g., 30 seconds). If the personnel do not return within the delay time, an off-duty alarm will be triggered, and the personnel will be notified through the local alarm 105. At the same time, the alarm information will be uploaded to the cloud data center 300.

[0048] Helmet removal alarm process: The human body sensor 104 continuously monitors the helmet wearing status. When the head pressure or heat source signal disappears, the main controller 101 determines that the helmet has been removed and immediately controls the local alarm 105 to issue an audible and visual or vibration alarm. The helmet removal alarm information is also uploaded to the cloud data center 300 for management personnel to handle.

[0049] Data Management and Analysis: All collected data is uploaded to the cloud data center 300 in real time via the IoT communication module 103;

[0050] The cloud-based data center performs statistical analysis on the data, generating attendance reports, personnel activity heatmaps, and high-frequency violation analysis reports, providing data support for safety management decisions.

[0051] This invention enables automatic and accurate contactless attendance tracking, improving management efficiency; it monitors personnel location and wearing status in real time, achieving proactive safety supervision; it is highly integrated with multiple functions, avoiding data silos; it combines local alarms with cloud notifications to improve the timeliness of safety alerts; and it enhances the overall level of safety management based on data analysis.
