Pulse Ai

The Heartbeat of Disaster Response

🌍 PulseAI — Real-Time AI-Driven Disaster Intelligence & Resource Orchestration

🧠 Inspiration

During disasters, information arrives too late, from too many places, and without coordination. Satellite images sit unused, tweets go unread, sensors raise alerts in isolation, and citizens file reports that take hours to validate.

We asked a simple question:

What if AI could continuously listen, reason, validate, and act — all in real time?

PulseAI was built to answer that question.

Our inspiration was to create a living, streaming intelligence system that:

  • Understands disasters as they unfold
  • Correlates citizen reports, satellite imagery, sensors, and social media
  • Automatically decides when deeper analysis is required
  • Triggers the right response workflows without human delay

💡 What PulseAI Does

PulseAI is an AI-native disaster response platform built on:

  • Flink for real-time streaming intelligence
  • ADK (Agent Development Kit) for multi-agent reasoning
  • MCP (Model Context Protocol) for secure, tool-driven execution
  • Google Cloud (BigQuery, GCS, Cloud Run) for scalable execution

At a high level, PulseAI performs four continuous intelligence loops:

  1. Citizen Case Analysis
  2. Satellite Damage Detection
  3. Sensor Anomaly Detection
  4. Tweet Classification & Verification

All of these flows ensure:

  • Deterministic execution
  • No duplicated actions
  • Fully auditable AI decisions

🔁 System Architecture Overview

Architecture Diagram

PulseAI is event-driven:

  • Every incoming signal (tweet, sensor alert, image upload, citizen case) enters Kafka
  • Flink Compute Pools process these streams
  • AI Agents reason over the data
  • MCP Tools execute real-world actions (queries, jobs, writes)
  • Results are persisted back to Kafka and BigQuery

🔁 Core Intelligence Flows

🧍 Citizen Case Analysis Flow

Citizen Case Analysis Flow

Flow Explanation

  1. Citizen submits a disaster case
  2. Case is summarized and pushed into a Kafka topic
  3. Flink AI Streaming Agent consumes the case
  4. The agent performs the following:
    • Queries tweet alerts via BigQuery MCP
    • Queries sensor alerts via BigQuery MCP
    • Forecasts required emergency resources
    • Fetches available nearby resources
    • Runs a custom resource allocation UDF
  5. The agent produces:
    • A complete disaster assessment
    • A resource allocation plan
  6. Results are:
    • Written to BigQuery
    • Published back to Kafka for dashboards and responders

🛰️ Damage Detection & Analysis Flow

Damage Detection & Analysis Flow

Flow Explanation

  1. A satellite image is uploaded to Google Cloud Storage
  2. A file-creation event is published to Pub/Sub
  3. Kafka ingests the event into Flink
  4. The AI Streaming Agent:
    • Fetches pre-disaster & post-disaster image pairs
    • Queries contextual alerts (tweets + sensors)
  5. The agent evaluates: > Is damage analysis required?
  6. Only if required, the agent:
    • Calls a custom MCP Server
    • Triggers the Satellite Damage Detection ADK Agent
  7. The damage agent:
  • Submits a Cloud Run Job
  • Performs image analysis
  • Summarizes damage severity
    1. Results are persisted into BigQuery

⚠️ Important Design Choice The MCP tool is fire-and-forget, ensuring:

  • No blocking
  • No retries
  • No duplicate job triggers

📡 Sensor Anomaly Detection Flow

Sensor Anomaly Detection Flow

Flow Explanation

  1. Live sensor data enters Kafka
  2. Flink runs ML_DETECT_ANOMALIES
  3. If an anomaly is detected:
    • An emergency alert is generated
  4. If not:
  • The event is ignored

This ensures early warning detection without overwhelming responders.

🐦 Tweet Classification Flow

Tweet Classification Flow

Flow Explanation

  1. Tweets stream into Kafka
  2. Flink AI Agent:
    • Classifies tweet criticality
  3. If critical:
    • Tweets are summarized
    • Added to emergency alerts
  4. Otherwise:
    • Ignored

This prevents misinformation from polluting response decisions.
