Description

Technical Field

[0001] This invention relates to the field of confined space operation safety management technology, and in particular to a confined space operation safety management system and method. Background Technology

[0002] In the daily operation and equipment maintenance of power plants, chemical plants, municipal facilities, and other industries, confined space operations, such as those involving pressure tanks, return tanks, gas tanks, and water collection wells, are common and high-risk processes. These confined spaces have complex internal environments, posing risks such as the accumulation of toxic and harmful gases, oxygen deficiency, and flammability and explosiveness.

[0003] Traditional confined space operation safety management methods mainly rely on manual inspections and simple gas detection equipment, which have the following shortcomings: 1. Insufficient personnel safety monitoring: Supervisors cannot monitor the physical condition of workers in confined spaces in real time (such as blood oxygen and heart rate), and cannot promptly detect abnormal signs caused by inhalation of toxic gases or excessive fatigue, thus delaying rescue opportunities; 2. Incomplete environmental monitoring: Traditional gas detectors have limited functions and insufficient accuracy, and cannot simultaneously conduct comprehensive, real-time monitoring and trend warnings of multiple key gases, resulting in slow response speeds; 3. Management processes rely on manual labor: Processes such as work approval, tool inventory, and process recording rely on paper documents and manual operations, which are inefficient, prone to errors, and lack full traceability; 4. Delayed emergency response: There is a lack of intelligent early warning and linkage emergency mechanisms, and after a hazard is discovered, decisions and operations often rely on manual intervention, resulting in slow responses.

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] like Figure 1 As shown, a confined space operation safety management system 100 according to an embodiment of the present invention includes a human feature monitoring device 101, a video monitoring terminal 102, a multi-parameter gas detector 103, an integrated operation vehicle 104, an education and training terminal 105, and an industrial control computer subsystem 106. The industrial control computer subsystem 106 is interconnected with the human feature monitoring device 101, the video monitoring terminal 102, the multi-parameter gas detector 103, the integrated operation vehicle 104, and the education and training terminal 105 through a wireless communication module to realize data sharing and remote linkage control. The system includes: a human feature monitoring device 101 for collecting physiological and behavioral characteristic data of workers; a video monitoring terminal 102 for collecting video information from the confined space work site; a multi-parameter gas detector 103 for real-time detection of gas conditions within the confined space; an industrial control computer subsystem 106 for fusing and analyzing the data acquired by the human feature monitoring device 101, the video information acquired by the video monitoring terminal 102, and the data acquired by the multi-parameter gas detector 103, and generating a status judgment result; a work integration vehicle 104 for carrying the human feature monitoring device 101, the video monitoring terminal 102, and the multi-parameter gas detector 103, for real-time autonomous inspection within the confined space; and an education and training terminal 105 for recording the training records and safety education videos of workers, enabling safety training and assessment management for workers operating in confined spaces. In this embodiment, a data storage module 107 is also included for distributed storage of data during the work process. The data storage module 107 is connected to the industrial control computer subsystem 106 via a wireless communication module.

[0020] This confined space operation safety management system adopts a technical architecture that deeply integrates hardware and software. The hardware part is used to collect multimodal data from the work site in real time, while the software part is used for intelligent analysis and safety management. The two are seamlessly connected through standardized communication protocols and data interfaces to form an organic whole. It can achieve multi-dimensional accurate detection, comprehensively ensure operational safety, and provide intelligent management throughout the entire process. This significantly improves the safety and emergency response efficiency of confined space operations, effectively reduces human error and the occurrence of safety accidents, and significantly improves operational efficiency.

[0021] See Figure 2The human characteristic monitoring device 101 includes a wearable sensor 1011 and a wireless transmission module 1012, used to realize real-time monitoring and data transmission of the worker's vital signs. Optionally, the human characteristic monitoring device 101 is a human vital sign measuring watch with a built-in high-precision biosensor, used to monitor and transmit data on the worker's pulse, blood oxygen content, body temperature, and activity in real time. The device supports low-power Bluetooth or ZigBee encrypted wireless transmission to ensure stable and secure data transmission. When the human vital sign data, such as blood oxygen content, body temperature, and prolonged inactivity, exceed preset values, an audible and visual alarm is triggered. When the worker's blood oxygen content is below 90%, body temperature exceeds 38°C, or the worker remains motionless for more than 1 minute (it should be noted that parameters such as duration, body temperature threshold, and blood oxygen content threshold can be set as needed), the industrial control computer subsystem 106 will immediately trigger an audible and visual alarm and simultaneously notify the on-site monitoring personnel and the remote management platform via SMS or APP push. In addition, the confined space operation safety management system 100 can also determine whether the operator is in a state of excessive fatigue based on the operator's exercise status and heart rate changes. If an abnormal fatigue signal is detected, or if the time the operator spends in the confined space is calculated, an early warning will be issued in a timely manner to remind the operator to rest and adjust.

[0022] See Figure 3 The video monitoring terminal 102 includes a video acquisition unit 1021, a data analysis unit 1022, and a first data transmission unit 1023. Specifically, the video acquisition unit 1021 is used to acquire real-time video of the work site within a confined space. This video is high-definition video, optionally 1080P or even 4K resolution. The data analysis unit 1022 analyzes the real-time video acquired by the video acquisition unit 1021 based on a deep learning algorithm. The first data transmission unit 1023 transmits the real-time video acquired by the video acquisition unit 1021 and the analysis results acquired by the data analysis unit 1022 to the industrial control computer subsystem 106 via 5G or Wi-Fi.

[0023] See Figure 4The multi-parameter gas detector 103 includes a gas detection unit 1031, a second data transmission unit 1032, and an alarm unit 1033. Specifically, the gas detection unit 1031 is used to collect gas composition data within a confined space; the second data transmission unit 1032 is used to transmit the gas composition data detected by the gas detection unit 1031 to the industrial control computer subsystem 106; and the alarm unit 1033 issues an alarm signal when the gas composition data detected by the gas detection unit 1031 exceeds a preset threshold. The gas detection unit 1031 uses electrochemical and infrared sensing technology to detect the density of gases such as oxygen, nitric oxide, hydrogen sulfide, and combustible gases in real time. Optionally, when the detected oxygen density is below 19.5%, or the density of toxic and harmful gases such as carbon monoxide and hydrogen sulfide exceeds the threshold specified by national standards, and the gas density is judged to be continuously increasing, the alarm unit will not only issue a high-decibel audible and visual alarm, but also automatically control the fan to start ventilation. At the same time, by analyzing historical gas data and using time series prediction algorithms, the gas concentration changes in the future period are predicted to prepare for contingencies in advance. For example, if it is predicted that the concentration of flammable gas in a confined space may reach 20% of the lower explosive limit after 1 hour, the system will issue an early warning, notify the workers to evacuate and take corresponding explosion-proof measures.

[0024] See Figure 5 The integrated work vehicle 104 includes a tool classification and storage unit 1041 and a movement unit 1042. Specifically, the tool classification and storage unit 1041 is used to classify and store work tools and equipment; the movement unit 1042 is used to enable the integrated work vehicle 104 to navigate autonomously within confined spaces. The tool classification and storage unit 1041 of the integrated work vehicle 104 adopts a modular structure, rationally integrating tools and equipment such as gas detectors, explosion-proof equipment, fans, power supply panels, walkie-talkies, positive pressure breathing apparatus, stretchers, oxygen bags, and masks, facilitating movement and one-stop retrieval of work tools. The movement unit 1042 adopts a universal movement mechanism, equipped with universal wheels and a braking device, enabling flexible movement in various confined space working environments such as narrow and complex production sites, improving movement efficiency and operational safety.

[0025] The education and training terminal 105 includes a video playback unit for playing educational content on confined space operations. Optionally, the educational content includes the main risks, precautions, confined space operation procedures, and confined space rescue guidelines for confined space operations, providing training and safety reminders to workers in video format to enhance their safety awareness.

[0026] In an embodiment of the present invention, the industrial control computer subsystem 106 includes a confined space management module 1060, which receives the analysis results of the industrial control computer subsystem 106, generates alarm information, safety reports, and risk warning instructions. Developed based on a cloud computing architecture, it supports distributed computing and data storage, and can process large-scale data streams in real time. The confined space management module 1060 uses convolutional neural networks (CNN) and long short-term memory networks (LSTM) deep learning algorithms to extract features and predict risks from data acquired by the human feature detection device 101, the video monitoring terminal 102, and the multi-parameter gas detector 103, ensuring the intelligence and efficiency of the device. Furthermore, the industrial control computer subsystem 106 communicates with each device in the system via an encrypted protocol, ensuring the integrity and tamper-proof nature of transmitted data, making it more secure and stable.

[0027] See Figure 6The confined space management module 1060 includes a work application and approval submodule 1061, a work preparation submodule 1062, a work management submodule 1063, a record generation submodule 1064, a work supervision and evaluation submodule 1065, a data fusion and analysis submodule 1066, an early warning and emergency response submodule 1067, and a system management and interaction submodule 1068. Specifically, the work application and approval submodule 1061 manages work applications, approval processes, and records approval information. This includes allowing workers to initiate work applications online, obtain approval plans and work orders, conduct work approvals according to preset processes, and record the approval process and results. The work preparation submodule 1062 is used to input photos of the task leader, task supervisor, and workers, and to check the ventilation, equipment types, and quantities in the confined space. Work can only begin after confirmation of compliance. The Operation Management submodule 1063 is used to verify the identity of operators via facial recognition only after the confined space has been ventilated and inspected and passed inspection. During the operation, it supports pause and stop operations. After pausing, the status changes to "Paused Operation," and the operator must complete the equipment removal registration before pausing or stopping the operation. To resume the operation, the operator must complete the equipment removal registration, and after the confined space has been ventilated and inspected and passed inspection, the operator must again verify their identity via facial recognition before starting the operation. An operation history record is automatically generated upon completion. Simultaneously, facial recognition authentication is performed on monitoring personnel periodically to ensure that monitoring personnel outside the confined space strictly fulfill their monitoring responsibilities. The Record Generation submodule 1064 automatically generates a record document after the operation, including information such as operation time, location, operators, environmental parameters, warning information, and operation results, and stores it in the system database or cloud storage. The Operation Supervision and Evaluation submodule 1065 monitors the operation process in real time and performs safety and compliance assessments, including handling alarms generated during the operation, supporting querying and analysis of historical operation data, and generating statistical reports on operation safety and compliance. The data fusion and analysis submodule 1066 is used to fuse and intelligently analyze the data acquired by the human feature monitoring device 101, the video information acquired by the video monitoring terminal 102, and the data acquired by the multi-parameter gas detector 103 to identify potential risks. This includes data calibration, feature extraction, and data correlation. Real-time analysis of the fused data is performed based on deep learning algorithms and an expert system. The early warning and emergency response submodule 1067 issues corresponding early warning information and activates emergency plans based on the results obtained from the data fusion and analysis submodule 1066.Optionally, the system analyzes and issues warnings when alarms are triggered by personnel lying down, prolonged inactivity, failure to wear safety helmets, overcrowding, violations, unauthorized entry, overtime work, abnormal gas conditions, low equipment power, or abnormal vital signs. It also automatically activates emergency plans such as turning on ventilation equipment, initiating emergency rescue procedures, and cutting off power to relevant equipment. Simultaneously, it records the time, location, and handling process of each event in detail for post-event analysis and improvement. The system management and interaction submodule 1068 is used to implement user management, equipment management, data interaction, and user interface functions. This includes automatically storing video data based on the status of the work task during operation. The video data includes video segments at the start, middle, and end of the work. Based on the task's identifier or timestamp, relevant video segments can be quickly retrieved and traced back. The system also manages and backs up the stored video data to ensure its security and traceability.

[0028] The working principle of the confined space operation safety management system of this invention is as follows: When a worker enters the confined space, the human characteristic monitoring device 101 begins to collect the worker's vital signs data in real time. The video monitoring terminal 102 and the multi-parameter gas detector 103 operate simultaneously, and the industrial control computer subsystem 106 receives and comprehensively analyzes various data. If abnormal indicators are detected, such as insufficient blood oxygen, excessive gas levels, work exceeding the time limit, or a worker falling to the ground, the system will immediately issue multi-channel alarms and activate the corresponding emergency response procedure. The data and video of the entire operation process are automatically archived for subsequent safety assessment and training analysis. The entire confined space operation safety management system 100, from worker training and assessment to operation execution and data traceability, can achieve full-process, full-element, and intelligent safety management of confined space operations, achieving the effect of closed-loop safety management.

[0029] The confined space operation safety management system 100 is built on a deeply integrated hardware and software technical architecture. The hardware components—human feature monitoring device 101, video monitoring terminal 102, multi-parameter gas detector 103, operation integrated vehicle 104, education and training terminal 105, and industrial control computer subsystem 106—act as the system's "senses" and "limbs." The software component, the confined space management module 1060, is the system's "intelligent core," while the industrial control computer subsystem 106, as the "brain center" of the entire safety management system, undertakes the critical tasks of data reception, processing, and command transmission. The confined space management module 1060 is developed based on a cloud computing architecture, supporting distributed computing and data storage, and possesses powerful big data processing capabilities. It employs convolutional neural network (CNN) and long short-term memory network (LSTM) deep learning algorithms to perform deep feature extraction and risk prediction on multimodal data, including data acquired by the human feature detection device 101, video monitoring terminal 102, and multi-parameter gas detector 103. For example, LSTM can be used to perform time-series analysis on the pulse and blood oxygen data of workers over a period of time to predict trends in their health status, and CNN can be used to extract image features from work videos to identify potential safety hazards. Optionally, the confined space operation safety management system 100 of this invention reserves 4G / 5G public network and private network interfaces to facilitate future network upgrades and transformations of the device, enabling remote monitoring and data transmission.

[0030] Based on the same inventive concept, this invention also proposes a method for safety management of confined space operations, see [link to relevant documentation]. Figure 7The process includes the following steps: First, in step S1, before the operation begins, safety training is conducted for the operators through the education and training terminal 105. The education and training terminal 105 presents the main risks, precautions, operating procedures, and rescue guidelines for confined space operations in video format, which the operators watch and learn through the industrial control computer subsystem 106. After the training is completed, the system automatically records the training time, learning progress, and completion status for safety confirmation before the operation. Then, in step S2, the operators put on the human characteristic monitoring device 101, start the multi-parameter gas detector 103 on the operation integration trolley 104, and simultaneously start the human characteristic monitoring device 101 and the video monitoring terminal 102 to collect multi-source data from the operation site in real time. Among them, the human characteristic monitoring device 101 is a human vital sign measurement watch, used to monitor the operator's pulse, blood oxygen content, body temperature, activity status, and other vital signs in real time, and transmits the data to the industrial control computer subsystem 106 through a low-power wireless network (such as Bluetooth or ZigBee). The video monitoring terminal 102 is used to collect video information in the confined space in real time. Its built-in AI analysis unit intelligently identifies and alarms based on factors such as whether personnel are wearing safety helmets, the number of workers, and whether personnel remain stationary for extended periods. The multi-parameter gas detector 103 monitors the concentrations of gases such as oxygen, carbon monoxide, hydrogen sulfide, combustible gas, ammonia, and sulfur dioxide in real time. After all equipment is activated, multi-source data is wirelessly transmitted to the industrial control computer subsystem 106 in real time. Subsequently, in step S3, the industrial control computer subsystem 106 performs fusion analysis on the collected data and generates a status judgment result. Then, in step S4, based on the status judgment result, the confined space management module 1060 executes work operations, including work application, review, preparation, management, recording, supervision, and evaluation, and generates early warnings or initiates emergency responses based on the analysis results. Finally, in step S5, after the work is completed, the wired space management module 1060 automatically generates a comprehensive analysis report containing work time, location, personnel, human characteristic monitoring data, gas detection data, early warning information, video clips, and work results. The report is generated by the record generation submodule 1064 and uploaded to the cloud data storage module 107 for archiving, ensuring data traceability and long-term preservation. Throughout the entire operation, all required equipment is uniformly configured by the operation integration vehicle 104. In this embodiment of the invention, intelligent monitoring and safety management of the entire confined space operation process are achieved through multimodal sensing methods such as human feature monitoring, multi-parameter gas detection, and video monitoring.
