Description

Technical Field

[0001] This utility model belongs to the field of hazardous and explosive space monitoring technology, specifically relating to an intelligent monitoring system for hazardous and explosive spaces in the fireworks and firecrackers industry. Background Technology

[0002] Fireworks and firecrackers production is a high-risk industry. During production, handling, loading, and unloading operations, chemicals, equipment, and people can easily generate and accumulate static electricity. When the energy of the accumulated charge exceeds the minimum ignition energy of the chemicals and is released in the form of an electric spark, it can easily cause a combustion or explosion accident, resulting in serious consequences. Therefore, effectively controlling the hazards of static electricity generated during the production process is one of the most critical aspects of ensuring the safe production of fireworks and firecrackers.

[0003] To this end, the national mandatory standard "Technical Specification for Prevention of Static Electricity Hazards in Fireworks and Firecrackers" (AQ4115-2025) puts forward clear technical requirements for workshops and warehouses in Class I and Class II static electricity sensitive areas: conductive (anti-static) work surfaces must be used, and their grounding resistance value must be strictly controlled within a specific range; the static grounding system must be securely connected; when the relative humidity of the ambient air is lower than the safety threshold, humidification measures must be taken; at the same time, it is required to test and record the grounding resistance regularly (with a cycle of no more than 6 months).

[0004] However, most companies in the industry still rely on traditional and outdated manual inspection methods. Safety personnel need to use handheld instruments to periodically measure grounding resistance, check the continuity of grounding lines, and inspect parameters such as ambient temperature and humidity, and fire water tank levels at various work surfaces. This method has many inherent drawbacks: First, it lacks real-time performance, making continuous online monitoring impossible and failing to detect transient faults such as excessive grounding resistance or sudden circuit breaks that occur between two manual inspections. Second, it has low reliability, as manual inspections are easily affected by factors such as operating procedures, instrument accuracy, and personnel responsibility, resulting in a high risk of missed or false inspections. Third, it has low management efficiency, as inspection data must be recorded manually, making it difficult to achieve electronic, systematic, centralized management and historical traceability of data, and even more difficult to link with higher-level emergency management platforms. This passive and intermittent monitoring model has significant safety lag, leaving the production process constantly exposed to unpredictable risks, posing a huge safety hazard.

[0005] Therefore, there is an urgent need for an intelligent monitoring system for hazardous and explosive spaces in the fireworks and firecrackers industry that can detect the grounding resistance and temperature and humidity of the space in real time and upload the detection results.

Therefore, when various working equipment are powered on and operating normally, the system can simultaneously start and stop and monitor the equipment in real time. The workbench, in the context of the fireworks and firecrackers industry, refers to the horizontal surface provided for product manufacturing, testing, and other workflow processes. It is not limited to a tabletop; in some implementation scenarios, the workbench can also be the ground. Correspondingly, the workbench resistance refers to the resistance of the grounding system through the workbench. Real-time monitoring of this resistance is the primary task of this system.
