3. ABSTRACT
This describes the use of IoT hardware and protocols.
This gear is a wearable glove device
which can be used in various work spaces where power tools
are being constantly used.
This proposed system is built around a micro-processor
acting as the central server.
At the same time many sensors are interfaced with
microcontrollers.
which act as the link for data transmission and perform
various tasks.
4. ABSTRACT CONTD...
The gloves contain safety features.
So workers are unable to use any dangerous power tools
without wearing proper equipment.
A simple sweep based camera module is used.
To live-stream the captured video whenever any power tool
is switched On.
This system proliferates the value of safety of a worker in a
factory floor.
5. INTRODUCTION
Power tools became a very important part of the factory
floor.
Everyday, millions of people go to work and operate
potentially life threatening machines.
Injuries in power tool related accidents, results a huge loss
of precious work-force and other resources.
The idea of Connected Machines is an appealing one.
It can be applied to the large as well as small scale
machines.
Internet-of-Things provides safety and improves efficiency
with help of the aforementioned ideas .
6. LITERATURE SURVEY
There have been a few attempts at building devices for
factory workers like the Australian SmartCap
Which measures brain activity to detect fatigue.
AIG, reportedly invested in Human Condition Safety(HCS), a
company which makes wearable devices.
monitor the workers in a factory.
There has been no significant product that directly monitors
the physical safety of the factory floor workers.
7. ADVANTAGES & DISADVANTAGES OF
EXISTING SYSTEM
Advantages
help to increases employee
productivity.
Wearables can help keep
employees safe.
Flexibility
Work from anywhere.
Convenience.
Enhanced communication.
Faster information process.
Greater information accuracy.
Automated reminders.
Benefits administration.
No drug level monitoring.
Disadvantages
Some privacy concerns
regarding wearables.
Equipments can be
heavy/Expensive.
Can cause irritation in heat,
side effects such as
headache.
Human error during
information input
Need specialized knowledge.
Fear of loss of confidential
data.
Costly technology to update
the system.
8. METHODOLOGY USED
Wearable can be included in any type of protective gear.
Screen on the wearable and physical button allows which
machine wants to work with.
This data and data from sensors allows Raspberry Pi to make
decisions.
A self-built capacitive sensor monitors if it is worn or not.
Wearable is provided a piece of protective gear.
Any additional gear required to be worn for specific machine will
have just the capacitive sensor.
This is analyzed by microcontroller.
Which act as an MQTT client.
Client send information to be server on the Raspberry Pi (MQTT
broker).
10. MQTT
Message Queue Telemetry Transport
ISO standard (ISO/IEC PRF 20922) Publish-Subscribe-based
“Light Weight” messaging protocol.
For used on the top of TCP/IP protocol.
Designed for connections with remote locations where a “small
code footprint” is required .
Or the network bandwidth is limited.
Publish-Subscribe message pattern requires a message broker.
They are responsible for distributing messages to interested
clients.
MQTT is highly secure IoT protocol.
Used to implement smart devices.
Requires broker/centralized server to act as a communication
link between all the connected device in the system.
11. MQTT CONT...
Raspberry Pi microprocessor broker.
Due to the small footprint of MQTT the data packets size are
smaller.
• Transmission of data takes lower time other IoT protocols.
• Consumer much less power during operations.
In compared with HTTP gigabit network 5100 ms/request,
MQTT’s average Publish-Subscribe latency 120 ms/loopback
request.
It is dependent on the availability of WiFi/plugged internet.
Due to which it has low range.
Can only be used in a local network in one isolated institution.
In which the operations of power tools are not going to be shared
outside the work place.
12. MQTT CONT...
It has several modes of usage.
PUBLISH function to send data to one of the channels.
SUBSCRIBE function to listen to the channel and receive
the transmitted data.
It consumes less power.
As it is being used in QoS 2 mode
The data is received is highly secure and not damaged in
any possible way.
QoS 2 mode increases the overall time of operation, but
increases the safety of the system.
Due to the small size of data
the overall increase in time is very low
and the quality of the system is not hampered.
13. METHODOLOGY USED CONTD...
Machines also have various sensors including temperature,
pressure, humidity etc.
Which regularly send data to the broker.
These data can be used by company for analysis and improve
the efficiency of factory-floor.
Depending on the availability of the required machines, the
broker publishes this information to the wearable.
If all the required conditions are met ,the broker authorizes the
microcontroller inside the machine to turn on the device.
And the system ensures that the person working with the
machine has the proper equipment on.
RFID stickers in additionally placed RFID readers ensure that no
tool is working while unattended.
15. METHODOLOGY CONTD...
Another dimension of safety is that checking the user is injured or
in pain.
For this, system captures sound from surroundings using a
microphone connected to the Rpi.
Sounds are captured in every 5s to reduce the load on Raspberry
Pi .
The sound is then send to Google speech-to-text service using a
simple API call.
API returns the text of the words spoken.
This sentiment of this text is then acquired using another API(IBM
Watson API).
Tone Analyzer which returns various sentiments like sadness,
happiness, anger etc.
And a score associated with each one of them.
This is used by our own logistic regression machine learning
algorithm
To determine if the factory worker is in pain and requires some kind
of immediate assistance.
16. ADVANTAGES & DISADVANTAGES OF
PROPOSED SYSTEM
Advantages
Increases the safety of the
system.
Due to the small size of data,
overall increase in time is
very low.
and quality of the system is
not hampered.
Enhances the quality and

Cost-effective.
Disadvantages
Need of hardware and software
maintenance.
Availability of Wifi/plugged
internet.
High maintenance cost.
17. FUTURE SCOPE
This product is aimed to cut down accidents due to improper
protective gear.
It is revolutionary product for the manufacturing industry.
Using the power of IoT and the standard protocol MQTT, the
product is developed.
That not only ensures safety of personnel working with large
machine, but also the machines themselves.
It is predicted that, by 2020 the power tools market will be at
34 Billion Dollars globally.
S.W.A.G aims to reduce the human error and reducing the
chances of accidents.
