Abstract: Annual flood season is the peak period of geological disasters in China, with a serious threat to the safe operations of pipelines and ancillary equipment. Research has been done on the meteorological and geological disaster warning technology of pipelines. By using information technology, warning categories and response standards are applied in the meteorological and geological disaster warning system to achieve the integration of collection, publishing, sharing, and notification of warning information. Meanwhile, the direct transmission of disaster warning information is realized via a variety of transmission methods to make pipeline operators able to quickly grasp the disaster impacts. Application examples in the meteorological and geological disaster warning system of pipelines verify the effectiveness of this technology's application.
