The document describes an eMetro emergency medical services dispatch system that utilizes a drag-and-drop user interface, MQTT message broker, and MySQL database. The 911 dispatcher interface allows dragging a patient icon to a hospital icon, which updates the database and publishes a message via MQTT. The system demonstrates technologies including PHP, jQuery, MQTT, and performing SQL joins on the database tables.

Abstract
The eMetro Medical Services dispatch system provides 911 operators a graphical drag-n-drop interface
to dispatch patients to a set of hospitals and provides automated publish-subscribe messaging to ER
hospitals using the Mosquitto MQTT message broker. All dispatch events are recorded in a MySQL
database.

5. Introduction
The eMetro Medical services dispatch screen displays the patient icon representing the patient to be
transported. The 911 dispatcher drags the patient icon to one of the hospital emergency room drop icon
spaces. When the drag patient icon is dragged and dropped on the hospital icon the database is updated
with the dispatch event date, time, patient ID and hospital ID.

System Model
eMetro Block Definition Diagram
The eMetro block definition diagram (bdd) below captures the major system components and
stakeholders.
Dispatcher User Interface
The eMetro Medical services dispatch screen displays the patient icon representing the patient to be
transported. The 911 dispatcher drags the patient icon to one of the hospital emergency room drop icon
spaces. When the drag patient icon is dragged and dropped on the hospital icon the database is updated
with the dispatch event date, time, patient ID and hospital ID.
6

7. When the patient icon is dragged to the hospital icon rectangle the database is updated with dispatch
information and a MQTT command is executed triggering the MQTT message broker to send a message
that the patient has been dispatched, see subscriber window below.
7

8. Dispatch Report
Pressing “Dispatch Report” button generates a report that is the result of a join between ‘hospital’ and
‘dispatch’ tables to produce a report of 911 operator patient date-time stamped dispatches to which
hospitals.
8

9. Mosquitto MQTT Message Broker
When the 911 dispatcher drags the patient icon to one of the available ER rooms a message is created
and published to the subscribing ER room. This is depicted in the terminal window for the subscriber
below.
9

10. Installing Mosquitto MQTT
Mosquitto MQTT is a message broker that supports version 3.1 and 3.1.1 of the MQTT protocol.
http://mosquitto.org
MQTT provides a method of carrying out messaging using a publish/subscribe model. It is lightweight,
both in terms of bandwidth usage and ease of implementation. This makes it particularly useful at the
edge of the network where a sensor or other simple device may be implemented using an arduino for
example.
Install commands:
sudo apt-get install mosquitto
sudo apt-get install mosquito-clients
One recommended install instructions from stackoverflow.
http://stackoverflow.com/questions/27534953/how-do-i-set-up-my-own-mqtt-server-with-mosquitto
sudo apt-get update
sudo apt-get install mosquitto
sudo update-rc.d mosquitto defaults
10

11. sudo /etc/init.d/mosquitto start
Getting Mosquitto Status & Stopping
sudo /etc/init.d/mosquitto status
sudo /etc/init.d/mosquitto stop
11

12. Mosquitto-Clients
This is two MQTT version 3.1 command line clients. mosquitto_pub can be used to publish messages to
a broker and mosquitto_sub can be used to subscribe to a topic to receive messages.
JQuery User Interface
The jquery user interface library (jquery-ui.js and other components) is used to support drag and drop
user interface functionality. You can download from jqueryui.com.
http://jqueryui.com/draggable/
12

13. 911 Dispatcher Command Center, PHP
File: testdrag6.php
Functions are to create a 911 drag-n-drop user interface displaying a patient icon and available hospital
emergency rooms. The 911 operator can then drag a patient icon onto a hospital icon and create a
dispatch order and message informing the hospital ER that a patient is being dispatched to their
hospital.

Windows Share Folder
Instructions
On the Ubuntu server open a terminal window and execute mount command with the root account:
mount -t cifs -o username=ioneil,password=cool //10.103.20.21/share /var/www/html/
17

18. Must have IP address of Windows machine. You open a command window within Windows.
Execute ‘cmd’ command in Start Window.
18

19. 19

20. Execute ‘ipconfig’ command.
20

21. Current IP address for Windows machine is 10.103.26.119.
21

22. Mosquitto MQTT Setup
Mosquitto MQTT has to be running.
Start Mosquitto by using the ‘mosquitto’ command. This terminal window will show mosquito events
such as when you create a subscriber and publish messages to the broker.
22

23. 23

24. Mosquitto Subscriber
Open another terminal window with another account besides root.
Execute the ‘mosquitto_sub –h localhost –t emetro’ command. This will subscribe to the topic ‘emetro’
and this terminal window will display messages published to the topic.
Mosquitto Publish
Now execute the publish command: mosquito_pub –h localhost –t emetro –m “hello jeff”
24

25. As you can see in the prior screen capture the subscriber window has received the “hello jeff” message.
These terminal windows are for subscriber hospitals what will receive MQTT messages when the patient
icon is dropped on the hospital icon.
MQTT Utility (Java)
http://www.eclipse.org/paho/
https://repo.eclipse.org/content/repositories/paho-releases/org/eclipse/paho/mqtt-utility/0.4.0/
mqtt-utility-0.4.0.jar is a Java utility for testing MQTT.
Alternatively the Paho Java library jars can be downloaded directly from the following URLs;
https://repo.eclipse.org/content/repositories/paho-releases/ - Official Releases
Execute the Jar file by double clicking on the file.
This executable Java file was stored in the c:/mtn/share/nodejs folder.
25

26. The 192.168.145.129 address for the Ubuntu server and port 1883 was used to connect to the MQTT
server, see below.
You can create/subscribe to a topic and test sending/publishing messages to the topic with this Java
MQTT utility.
26

27. Example subject of “emetro” with test message of “hi kevin”

28. Database Tools: phpMyAdmin
MySQL is the database. Log into phpMyAdmin to administrate the database.
