A Mobile App Enabled School Emergency Response Solution
Our Customer Wanted a reliable communication system so that events leading to emergencies can be monitored and responded to at schools or buildings.
Results / Outcomes
Instant communication of events throughout the school buildings of several hundred classrooms is achieved by using multiple communication technologies. A ZigBee based large mesh network propagates events to hubs located throughout the facility to give audio and visual alerts.
Mobile apps help staff members receive instant updates on the situation and have a walkie-talkie-type voice communication facility.
High accurate location identification in the floor plan of the school, enabled the emergency responders to reach the event location quickly.
The entire system can be customized to generate different audio and visual alerts based on the requirement of the school and can be easily integrated with intercom and or other existing communication facilities in schools or building.
The desktop apps provided a view of the alerts in real time with aggregation capability for external emergency teams like police headquarters.
The System Description
The alert management system consisted of multiple components like Mobile Apps, Cloud application, Communication gateway, Hub, and a desktop application
Mobile App was designed, tested and deployed that will alerts staff members on new events as they happen. Staff members can generate, escalate, and close alerts. The features like walkie talkie and integration with schools existing alert management system will help to take quick action during alert events.
Cloud Application - Customized the cloud application to manage provisioning of multiple Gateways and associated Hubs and badges. The application coordinates the communication between Gateways, mobile apps, desktop apps and web applications.
MQTT protocol is used as communication protocol between cloud and gateways. REST API and Web sockets are used to interact with cloud and client applications.
