IoT Disaster Contact Routing for Smart City Notification Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In post-disaster scenarios, especially in smart cities, there is a challenge in efficiently confirming the identity and contact information of disaster-stricken individuals and sending timely notifications to their contacts, leading to communication occupation issues due to inadequate contact notifications.
Innovation Solution
A method and system for post-disaster contact in a smart city based on Internet of Things (IoT), which involves obtaining event-related information through a sensor network platform, determining the status and information of related objects, identifying appropriate contact persons, and sending notification messages to them via a user platform and service platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact notifications are sent to all possible contacts of disaster-stricken persons, then the probability of successful contact is improved, but communication occupation increases
Solution Approach 1:
The patent applies local quality by differentiating contact notification strategies based on disaster severity levels. For general disasters, only immediate family members are notified, while for severe disasters, the notification scope expands to include friends and colleagues. This differentiated approach optimizes communication resource usage while maintaining adequate contact success rates for each disaster scenario.
Solution Approach 2:
The system dynamically adjusts the contact person determination based on real-time disaster status information. The management platform receives disaster information, evaluates the severity level, and automatically modifies the notification scope accordingly. This dynamic adjustment ensures communication resources are allocated efficiently without compromising contact reliability.
2Measurement precision
If manual confirmation of disaster-stricken person identity and contact information is performed, then accuracy is improved, but time consumption increases
Solution Approach 1:
The system implements self-service by automatically determining contact persons using IoT sensor data and pre-established relationship databases. The management platform autonomously identifies disaster-stricken persons, retrieves their contact information, and determines appropriate contact persons without requiring manual intervention. This automation maintains high accuracy through structured data while dramatically reducing time consumption.
Solution Approach 2:
The patent applies preliminary action by pre-establishing relationship databases that store contact information and relationship types before disasters occur. When a disaster happens, the system quickly queries these pre-prepared databases to determine contact persons, eliminating the need for time-consuming manual information gathering while maintaining accuracy through validated pre-stored data.
3Adaptability or versatility
If the scope of contact persons is expanded to include friends and colleagues, then communication coverage is improved, but communication occupation increases
Solution Approach 1:
The patent implements local quality by tailoring the contact notification scope to the specific disaster scenario and individual case. The system evaluates disaster severity and individual circumstances to determine whether to include friends and colleagues in notifications, rather than applying a uniform expansion policy. This targeted approach improves adaptability to different situations while controlling overall communication occupation.

AI summary
The embodiments of the present disclosure provide a method for post-disaster contact in a smart city based on Internet of Things, which is applied to a management platform. The method comprises: in response to the occurrence of a disaster event, obtaining event-related information from an object platform through a sensor network platform; determining information and status of one or more related objects based on the event-related information; determining one or more contact persons who need to be notified based on the information of the one or more related objects; and sending notification information to the one or more contact persons by sending the notification information to a user platform through a service platform.
