Problems solved by technology
[0002] With the frequent occurrence of hazardous chemical explosion accidents in the petrochemical industry, the application of gas detection and alarm equipment has become more and more extensive, covering all stages of the petrochemical smelting industry, including transportation, storage and transportation, pipelines and routine inspections. It is required to carry certain gas detection and alarm equipment and wear safety helmets at the same time. The current method is that the inspection personnel wear safety helmets on their heads and hold gas detection and alarm devices. However, this will cause the inspection personnel to occupy their hands and cannot flexibly respond to various emergencies. situation
