User group
� This application is intended for all those
areas of automation that use computational
devices for controlling or monitoring a
process and that would like to retrieve SMS
alerts without having GSM enabled devices
� Areas
� Home automation
� Surveillance systems
� Factories
� Hobbyists etc.
Traditional GSM
enabled devices
• Devices requires GSM modem and at least serial
communication port
•Communication between the devices and the GSM
should be implemented using the adequate AT
commands
•A dedicated SIM card per each GSM modem is needed
•Programming the necessary logic has to be done in the
devices to avoid an overflow of SMS in case of repetitive
alarms in a short period of time.
•Different communication protocols involved (need for
gateways)
Traditional GSM enabled devices architecture
RS232
link
Filed
busSerial
protocol
Message flow control has to
be programmed in the device
Contact lists and numbers
should be changed in the
device or gateways,
connecting directly to each of
them
Communication protocols have to
be understood by gateway and
device (communication interface
coupling)

With
embeddedmonitor.com
•If a device has Ethernet communication
capabilities then it can be enabled with
GSM communication with the proposed
architecture
•GSM communication capabilities can be
“embedded” virtually in Ethernet devices
Architecture description� Ethernet devices or any device that supports TCP/IP (WiFi, etc.) can be
implemented with HTTP so that it can post messages to a server.
� Posted messages can be sent as SMS by using a mobile operator server
� Messages are sent to users who are subscribed to the messages sent by the devices.
� Messages are not send necessarily immediately when received. A delay can be set so if an alarm is solved before its delay period, then message in the SMS queue is cleared
� When a SMS is going to be sent, it goes to an authorization stage that authorizes or denies the SMS sending according to the SMS flow control policies (Ex, Maximum number of SMS per account, user, etc.)

Benefits of the proposed
architecture
� All the elements speak the same protocol: HTTP
� All the next tasks can be done from an unique
control point (embeddedmonitor.com server)
� Manage contacts lists
� Manage device lists
� Subscriptions from contacts to devices
� SMS flow control (restrictions)
� Messages visualization and storage
� No needs of SIM cards, GSM gateways/modems
� Easy communication by posts to the server
Potential use of the platform
(1/2)
� “By 2010, devices connected to the Internet will reach 35 billion (nearly 6 devices per person on the planet).” -Cerf, Vinton, "Cerf's Up: Social, Economic and Regulatory Issues: Internet in the Next Five to Ten Years." 2000 WorldCom, Inc.
� “By 2020, so many appliances, vehicles, and buildings will be online that it is likely there will be more Internet devices than people online at any given moment.” -Cerf, Vinton "Visions of the 21st Century: What Will Replace the Internet." TIME.com(June 19, 2000).
Potential use of the platform
(2/2)
� Devices with Ethernet capabilities can be found in the market like:� Arduino with ethernet shield (famous hobbyists
gadget)
� S1000 industrial controller unit with ethernetcommunication and web services (from INICO technologies)
� Chips like ENC624J600 give microcontroller ethernet capabilities in an easy way.
� Applications used in industry or laboratories can be connected as any other device to the platform, through a virtual device application installed in a computer.
� Ex. LabView from National Instruments
What is
embeddedmonitor.com ?
It is a website that implements the described proposed architecture.
Its meant to be used as a platform for developing applications that require monitoring, SMS alerts, etc.
The application range depends on the user needs. (Surveillance, factory, home automation, etc.)
Technologies involved in
embeddedmonitor.com
� HTTP communication
� SOAP and URL encoded data transfer
� XML documents (navigation and storage)
� SQL queries
� Publisher/subscriber asynchronous communication schema
� RESTful web services
� Some principles of message brokers
Using your account
Sign in
username: luis
password: demo
Add devicesIn MyDevices add devices to your account
(position of the device can be stored)
Add SMS contacts
� Add SMS contacts
� The format of the mobile phone should be like
358XXXXXXXXX (don’t include +)
� Clicking on the mobile
phone allows user to
call through skype or
send SMS to the
contact
Add subscriptions(1/2)� When a device (publisher) reports a message, a contact (subscriber) will receive the message if is subscribed to that device and group
Add subscriptions(2/2)
� Messages from devices can be targeted to specific groups.
� For example, if a device runs out of material it can send a notification to the supplier group subscribed person(s), or if a operational failure occurs it can notify to the maintenance group subscribed persons.
� Examples:
� Luis receives messages targeted to group B from all devices
� Lalo receives all messages from TempController_1 device
� Marta receives messages targeted to group C from tut14 device
Modify Settings(1/2)� Here it is possible to limit the flow of messages by
setting limits like: maximum number of SMS that
each device can send in one hour
� It is possible to visualize the
current value of those
variables. Very often SMS
are not forwarded to users
because one of those
conditions has reached its
limits
Modify Settings(2/2)
� For this application two conditions were implemented, but more conditions could be set if a more strict SMS flow control is required like:
� Maximum number of SMS to a contact/group per hour/day etc.
� Maximum number of SMS from messages with an specific ID
� Maximum number of SMS per message
� Maximum number of SMS for each device (some devices might have bigger priorities)
� All these conditions can be integrated in the same way to the authorization block that decides if the system is allowed to send the SMS
� Customizing the SMS flow control can be done easily for each device within the same framework
Messages log
� Received messages (no matter if they are
targeted to an SMS contact) are shown in
this section� Reset messages are
highlighted
� Field tag names are
shown if they change
from the previous
message. So the user
can configure the
message field names
and number of them
whenever is required.
� The system is flexible
to display those
changes
Quick start for testing
the system
Real and virtual devices
� The system was tested with a real device:
� The S1000, a controller unit that has ethernet and web
services capabilities http://www.inicotech.com/
� For debugging and testing purposes, a virtual
“device” was used. It is a website that sends the
same *SOAP message that the real unit sends. The
server does not know if the message comes from a
PC, a controller unit or a virtual device
*SOAP protocol was used for this case but
it can be changed to any other protocol
over HTTP
Soon there will be a video on the website
of the system working with a S1000
Emulating the message
� The message emulator or virtual device can
be accessed from:
� http://www.embeddedmonitor.com/test/
� Or from the link emulate message in the
navitagion bar:
Message emulator view
Internet
Industrial controller
embeddedmonitor.com
server
Message
emulator
This message is the one that the ethernet
device requesting the server services sends
Editing message body� Messages should contain the
Msg root element
� The number, name of fileds and
value of fileds are flexible and
they are decisions of the user.
� Recommended 5 fields.
� The message body contains the
information the device needs to
log, or target to SMS contacts
Msg element attributes (1/3)
� The Msg root element can have the next attributes:
� Key: Generated in My devices when adding a new device. 5 length code used to identify the device unit sending messages to the server. Ex. Key=“ViHFh”
� Dly: (integer)Amount of minutes that the system is going to wait before sending an SMS to the subscribed contact if not Reset message is received. Ex.
Dly=“3” (if no reset message received within the next 3 minutes an SMS is sent)
Dly=“0” (an SMS is sent as soon as received)
Msg element attributes (2/3)
� Grp: Group to which the SMS is targeted. Contacts
subscribed to this group and device will receive the
SMS.
� Possible values: A,B,C,*
� If * is chosen the message is targeted to all the groups
Ex. Grp=“A” or Grp=“*”
� Reset: If this attribute is present with the value of
True, the message is a reset message and will
cancel all the messages in queue intended to be
sent as SMS
� Ex. Reset="True"
Msg element attributes (3/3)
� The next shows which parameters are
required for each type of message:
� Message without SMS targets
� Required: Key
� Message with SMS targets
� Required: Key,Dly,Grp
� Reset message
� Required: Key, Reset=“True”
Response from the server
� In the response from the server it is possible to see some useful data for debugging like: � contacts found as subscribed
� Content of message (body)
� If authorization fails it shows the reasons like in the last red box (If messages are sent with Dly>0 the authorization can not be visualized since it is computed when the deadline arrives)
Message storage and SMS
targeting
� Once the Message is received it is saved in
the database and they can be visualized in
the link of: Messages log in the user account
� When the system sends SMS these changes
can be visualized in the link of: Settings .
� If SMS are not being authorized most likely is
because the constrains are met. Recommended
to increase the constrain limits
Using embeddedmonitor.com
from an Excel file
� A simple macro in an Excel file can post data in embeddedmonitor.com
� The data is encoded in the URL of the post (simple)
� The message attributes described in the previous example remains the same
� Since the macro runs in VBA it can run in other Microsoft Office programs like:
� MS Access, Word
