Technical Field
[0001] This invention relates to the field of geographic information management technology, and in particular to a geographic information management system and management method for emergency response. Background Technology
[0002] Oil pipeline leaks are a common occurrence in oil and gas extraction, transportation, and storage. If not handled promptly, they can cause serious environmental pollution and threaten people's lives and property. Fires also pose a serious threat to people's lives and property. Therefore, it is crucial to develop comprehensive emergency response plans to enable rapid response and handling in the event of leaks, fires, or other emergencies, thereby minimizing accident damage and property losses and reducing negative impacts.
[0003] Geographic Information Management Systems (GIS) provide users with the information and insights needed for decision-making through data analysis and simulation, thereby helping users make informed decisions. However, existing GIS systems can only send alarm messages to system users when a crisis occurs, and then send emergency alarms to relevant units (departments) in the local area through manual intervention. Therefore, they cannot react quickly at the first moment when a crisis occurs, delaying the best time for emergency response and causing great harm to people's lives and property.
[0004] Therefore, to address the aforementioned problem of the inability to automatically send emergency alarms to relevant units in the local area, a system and management method that can send emergency alarms to relevant units in the local area can be designed. Summary of the Invention
