Solution Overview
Problem
Current public warning systems, including sirens, fail to provide effective communication during disasters, especially for people with hearing impairments and in environments where regular communication is disrupted, and lack dynamic network structures for reliable accessibility.
Innovation Solution
A self-sufficient network system using KatControllers that can connect to various entities and external sources, enabling geographical addressing for precise information transmission through different protocols, including LoRaWAN and mesh networks, to ensure continuous and reliable warning and communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sirens are used for public warning, then acoustic warning can be provided, but people with hearing impairments cannot receive the warning and the system lacks accessibility
Solution Approach 1:
The warning system is segmented into multiple independent signaling channels (acoustic siren, visual strobe light, text-to-speech) that can operate separately or together. This allows the system to provide effective warnings through appropriate channels depending on the user's needs and environmental conditions, resolving the contradiction between reliable warning delivery and accessibility for diverse user groups including hearing-impaired individuals.
Solution Approach 2:
The controller is designed to control multiple types of warning devices (acoustic sirens and visual strobe lights) through a single unified system. This multi-functional approach ensures that the same control infrastructure can serve diverse user needs, making the warning system universally accessible while maintaining reliable warning effectiveness across different scenarios.
2Area of stationary object
If sirens are deployed at fixed central locations, then coverage area is limited, but communication capability during crises is lost
Solution Approach 1:
The system transitions from static, fixed-location sirens to dynamic mobile units equipped with both acoustic and visual warning capabilities. These mobile units can be deployed to various locations during crises, expanding coverage area while maintaining communication reliability through their self-contained power supplies and multiple signaling modalities that work independently of fixed infrastructure.
Solution Approach 2:
The controller acts as an intermediary between the power supply system and the warning devices, enabling mobile units to operate autonomously during power outages. The controller manages power distribution and coordinates the operation of acoustic and visual devices, allowing communication to continue reliably during emergencies even when grid power is unavailable.
3Measurement precision
If siren addressing is made geographical and precise, then information transmission accuracy improves, but system complexity increases
Solution Approach 1:
The system uses GPS coordinates as a standardized parameter system to define warning areas, transforming the addressing complexity into manageable geometric parameters (circles, polygons). This approach maintains high location accuracy for precise information transmission while reducing addressing system complexity by using universal coordinate systems and standard geometric shapes that can be easily processed and communicated.
4Adaptability or versatility
If visual signals are added to sirens, then information can be provided to hearing-impaired people, but energy consumption increases
Solution Approach 1:
The visual strobe light operates in periodic flashing patterns rather than continuous illumination, significantly reducing energy consumption while maintaining effective visual warning capability for hearing-impaired individuals. The controller activates the strobe light only during warning events using periodic flashing sequences, allowing the system to provide enhanced accessibility without sustained high energy demand.

AI summary
The invention belongs to the technological field of emergency management, specifically disaster communication (DCT). The invention relates to a method for warning, communication, and emergency call control in self-contained networks. For this purpose, a network (DCT network) comprising disaster controllers is provided. The disaster controllers are partially connected to entities. Trigger events are processed from the entities, disaster controllers, and/or external sources. Based on a trigger event, control commands are sent from the entities, with the control commands being selected based on the trigger event and assigned to disaster controllers and/or geographical areas. The control commands are retrieved by the disaster controllers and generate a signal. Receiving and/or sending occurs via individual addressing, group addressing, area addressing, and/or remote addressing.Furthermore, the invention relates to a system for carrying out the method and a computer program product.
