Project Name: Realtime Vehicle Location Simulating and Monitoring System

Author: Cheng Wei

Overview:

Vehicle Location Simulating and Tracking System is a real-time application which can simulate cars' moving path and monitor all the vehicle's real time info including position, direction and speed on the map.

Features:

  • User can see all vechicle's current positions directly through the Google Map
  • User can see vehicle's detailed information such as current direction, speed, vechicle's Id, owner's info and so on through side bar
  • User can see the Supply location's (eg. Gas Station) detailed info on the Google Map

System UI:

System Architecture:

Microserves:

  1. Netflix Eureka as service registration and discovery

  2. Location Service: to supply the original vehicle's info(vehicle's status, owner's info, etc) to the end user and load into Database(initialization)

  3. Supply Service: to supply the Gas Stations' info to the end user and store it to the database(initialization)

  4. Location Simulator: to simulation the real-time location updates, it provides REST api for user to start and stop simulator

  5. Location Distribution: to disbution the location updates to MessageQueue(RabbitMQ)

  6. Location Updater: to Consume the locations updates in the MessageQueue, and return the updates to browser through Websocket

  7. used Hystrix as circuit breaker

Besides, the system incorporated , used Spring Boot Actuator to monitor application health

Technology Track:

  • Backend: Java, Spring Boot, Spring Data, Spring Cloud, Netflix OSS, SQL, JPA, Maven, Tomcat, WebSocket, RabbitMQ, REST
  • Frontend: HTML/CSS, Javascript, Bootstrap
  • Databases: MongoDB, H2
  • Tools: Git, Docker, Vagrant, IntelliJ IDEA

How to run the system:

  • Service Start Sequence

    1. docker-compose up
    2. sh ./start-eureka.sh
    3. sh ./start-location-simulator.sh
    4. sh ./start-location-ingest.sh
    5. sh ./start-location-updater.sh
    6. sh ./start-fleet-location-service.sh
    7. go to fleet location service folder and run sh ./upload-fleet.sh
    8. sh./start-supply-location-service.sh
    9. sh ./start-dashboard.sh

  • UI

    1. Open Dashboard UI on http://localhost:8080

    2. Open Simulator UI on http://localhost:9005

    3. Click run button to start simulation

    4. Click stop button to stop simulation

    5. Open Eureka UI on

      http://localhost:8761
