Technical Field

[0001] This application relates to the field of confined space operation safety technology, specifically to a multi-scenario confined space intelligent management method and system based on safety helmets. Background Technology

[0002] A safety helmet is an important piece of personal protective equipment, primarily used to protect the head from accidental injuries. Its core functions include: 1. Impact protection: In construction, mining, and factory work environments, safety helmets can withstand direct impacts from falling tools, gravel, steel bars, and other hard objects, dispersing the impact force and reducing head injury. 2. Protection against falling objects: In high-altitude work or multi-story construction sites, safety helmets effectively cushion the impact of falling objects (such as bricks and tools), preventing skull fractures or concussions. 3. Protection against electric shock: Electrician-specific safety helmets typically use insulating materials (such as fiberglass and modified plastics) to prevent electric shock accidents and reduce damage to the head from current. 4. Anti-static properties: Safety helmets in certain special locations (such as petrochemical plants) have anti-static functions to prevent sparks from igniting explosions.

[0003] Since construction workers are required to wear safety helmets when entering the construction site according to regulations, the safety of the construction site can also be monitored based on the safety helmets, forming a joint prevention and control system.

[0004] Currently, smart safety helmets suffer from insufficient functional adaptability in limited work spaces across various scenarios, and are difficult to integrate with safety supervision and monitoring equipment within those scenarios to form a joint prevention and control system.

It analyzes and summarizes the functional requirements and design principles of smart safety helmets in different scenarios within limited work spaces, and proposes methods for improving and optimizing smart safety helmet products suitable for different scenarios. Based on this, it focuses on the data acquisition and human-computer interaction functions of smart safety helmets to achieve safety in confined space operations and rapid detection and suppression of toxic and harmful substances.

[0012] Furthermore, the multi-scenario unsafe behavior recognition model is constructed by combining machine learning, deep learning, and AI vision.

This database is established by dividing unsafe behaviors in a limited workspace into scenarios.

[0022] Example 1 A multi-scenario, confined workspace intelligent management method based on safety helmets includes: S1, classify unsafe behaviors in a limited workspace according to scenarios and establish a database of unsafe behaviors for multiple scenarios; S2, train a multi-scenario unsafe behavior recognition model based on data from a multi-scenario unsafe behavior database; S3 inputs the data collected by the safety helmet into the unsafe behavior recognition model for multiple scenarios and outputs warning information about unsafe behaviors.

[0023] Furthermore, the limited working space includes: tunnels, sewage pipes, and deep foundation pits. Step S1 specifically includes the following steps: In tunnel scenarios, unsafe behaviors include: not wearing protective equipment or respiratory protective equipment; malfunctioning emergency lighting; entering the warning zone too early after blasting; smoke detection; smoking in violation of regulations; and not using ventilation equipment.

[0024] In the context of sewage pipelines, unsafe behaviors include: going down into the well without detecting gas; not wearing protective equipment; not wearing respiratory protective equipment; not wearing a five-point safety harness; working without supervision; and not using ventilation equipment.

[0025] In deep foundation pit scenarios, unsafe behaviors include: undetected gas entering the pipe jacking area directly; not wearing protective equipment; not wearing respiratory protective equipment; not wearing a five-point safety harness; working without supervision; not wearing a five-point safety harness; smoke and fire detection; and not using ventilation equipment.

[0026] To address the issues of redundant functional design and insufficient application relevance in current smart safety helmets for different scenarios, this paper analyzes the functional requirements of smart safety helmets in confined spaces under conditions of limited working space, such as tunnels, sewage pipelines, and deep foundation pits, and proposes a functional division scheme for smart safety helmets in different scenarios. The characteristics of confined working space scenarios and their corresponding functions are shown in Table 1. Table 1. Characteristics and corresponding functions of confined workspace scenarios

[0027] Furthermore, the data collected by the safety helmet includes vital sign sensing data, image data, and gas data. This data, after feature fusion, is input into a multi-scenario unsafe behavior recognition model. Taking the three functions of the smart safety helmet—gas detection, vital sign recognition, and safety helmet video recognition—as a starting point, sensor technology, machine learning and deep learning technology, multi-feature fusion technology, and AI vision technology are used to optimize these three functions, improving their usefulness and reliability, thereby achieving an overall enhancement of the smart safety helmet's functionality.

[0028] Furthermore, the multi-scenario unsafe behavior recognition model is constructed by combining machine learning, deep learning, and AI vision.

[0029] Example 2 Based on the same concept, a multi-scenario confined workspace intelligent management system based on safety helmets was also proposed, including a safety helmet with a data acquisition device, a processor, and a monitoring device; The safety helmet equipped with a data acquisition device is used to collect data and input the collected data into a processor. The processor is used to output early warning information of unsafe behavior based on the unsafe behavior identification model of the collected data; Monitoring devices are used to output warning signals based on early warning information about unsafe behaviors; The unsafe behavior identification model for multiple scenarios is trained based on data from a database of unsafe behaviors in multiple scenarios. This database is established by dividing unsafe behaviors in a limited workspace into scenarios.

[0030] Furthermore, a hardware design framework for an intelligent safety helmet is established. Through the rational design of the data acquisition unit and control unit, the product characteristics of stability, durability, lightweight, and low cost are met. The safety helmet with the data acquisition device collects data including vital sign sensing data, image data, and gas data. A schematic diagram of a specific safety helmet is shown below. Figure 2 , 3 As shown in Figures 4 and 5, taking the three functions of smart safety helmets—gas detection, vital sign recognition, and video recognition—as a starting point, this study employs sensor technology, machine learning and deep learning technology, multi-feature fusion technology, and AI vision technology to optimize these three functions, improving their usefulness and reliability, thereby achieving an overall enhancement of the smart safety helmet's functionality. Figure 1 As shown, the front of the safety helmet is equipped with a light, a camera, and an infrared laser head for collecting image and video information, such as... Figure 2 As shown, the safety helmet has a gas detection device at the back and ventilation holes at the top. Figure 4As shown, there are also warning lights on the rear to alert those in the vicinity who are wearing helmets. Figure 4 As shown, the helmet also contains a USB port, a magnetic charging port, a battery mounting component, an emergency call button, a photo / record button, a vital signs sensor, a voice intercom button, and power on / off and volume control buttons.

[0031] Furthermore, the processor centrally collects, analyzes, and automatically issues instructions for data in various scenarios; multiple safety helmets establish an interconnected safety control network to achieve joint prevention and control.

[0032] To fully leverage the data value of multi-source data collected by smart safety helmets in multi-scenario safety control, an adaptive data collection and management system was developed based on the characteristics of safety control in each scenario. This system was then interconnected with other safety supervision and monitoring equipment (voice broadcasting, video surveillance, disaster monitoring, etc.) within the scenario to establish a joint safety control management system, thereby achieving multi-device joint safety control centered on smart safety helmets.

[0033] The beneficial effects of this invention are: 1. Based on the characteristics of various confined workspace scenarios, this study analyzes the functional requirements of smart safety helmets for confined spaces in multiple scenarios. Building upon this analysis, the functional design of the smart safety helmet is optimized from hardware sensor acquisition and control units to software system implementation. This optimization effectively addresses the current problem of insufficient environmental adaptability of smart safety helmets, reduces their performance burden, and improves the reliability of functional applications. This is the first anticipated innovation of this research. Compared to current commercially available smart safety helmet products, this research demonstrates a certain degree of advancement.

[0034] 2. Unsafe behaviors in confined work spaces are categorized by scenario, and image databases of unsafe behaviors for each scenario are established. Based on these databases, unsafe behavior recognition models for each scenario are built using AI visual recognition technology. This enables intelligent recognition and real-time early warning of unsafe behaviors in confined work spaces across multiple scenarios, effectively improving the efficiency of on-site safety management. This is the second expected innovation of this research. Compared with similar technologies, this research has strong advancements and is expected to reach a leading level in China.

[0035] 3. By establishing a multi-device linkage mechanism in a confined workspace and conducting joint control based on a software system, the goal of achieving joint safety prevention and control can be realized, effectively improving the level of joint safety prevention and control in various confined workspace scenarios. This is the third expected innovation of this research. Compared with similar technologies, this research has good advanced features and is expected to reach the advanced level in China.
