Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of monitoring systems, and particularly relates to a monitoring system for confined space operations. Background Art
[0002] In many industries, confined space operations are a common task, such as in the oil, chemical, and power industries. Confined space operations are characterized by high risks and complex environments, with many potential safety hazards. Due to the limitations of the space in traditional confined space operations, there are many difficulties in environmental monitoring, personnel access, and tool management.
[0003] Currently, most confined space operations mainly rely on manual monitoring. However, manual monitoring has the following disadvantages: 1. Manual monitoring largely depends on the experience and subjective judgment of the operators, which may lead to the neglect or misjudgment of safety risks. 2. Manual monitoring usually can only obtain limited spatial information, and the monitoring results are limited by the knowledge of the monitoring personnel, monitoring devices, and time. 3. Manual monitoring often cannot achieve real-time monitoring, and accidents may occur during the monitoring intervals. 4. The operators entering the confined space for monitoring themselves may be at risk, such as high concentrations of harmful gases or insufficient oxygen in the space, which may cause harm to the operators. 5. The data records of manual monitoring may not be standardized or analyzed in a standardized manner, making subsequent risk assessment and accident analysis difficult. 6. In case of an emergency, manual monitoring may not be able to detect dangerous changes in time, resulting in a delay in the emergency response. 7. Manual monitoring requires specialized operators. 8. Manual monitoring usually cannot achieve long-term or continuous monitoring, which may lead to monitoring blind spots. Summary of the Utility Model
