My solution for this involves IoT device fixed on the safety jacket which is called Smart safety jacket.The Smart Safety Jacket enables complete safety of the employees working in mining and construction industries by installing a different type of sensors like Temperature sensor, Humidity sensor, Ultrasonic sensor, Motion sensor, Gas sensor, Sound sensor, RFID, Emergency Panel, and Notification Panel. These sensors connected to the network through Wi-Fi makes more relevant and valuable ever than before. In case of emergency, immediate notification will be sent to an admin who is monitoring entire miners in the mining industry and immediate action will be taken to rescue miner from the hazard. The whole process can be stated in two points. 1. The miner has to wear the smart safety jacket (connected with the sensors) which is connected to the control room via a network. 2. A Monitor in the control room who is continuously monitoring the miners and the mining site should check the hazard status and alert and rescue the miners in case of any critical situation. Thus the mining environment and miners will be protected from the hazard.

SMART SAFETY JACKET

2. INTRODUCTION
 The underground mines and construction sites all over the world are
adversely affected by various hazards including gaseous
explosions, landslides, accidents, Chemical leakage, fire hazards,
collapse, electrical hazards etc.
 This leads to the significance of safety for the mine workers.
 A better communication technology has to be employed for an
intelligent sensing and warning system .

4. Solution
Solution
 IOT device is fixed on the safety jacket .This smart jacket is fixed with 9 useful
sensors for monitoring the mining environment.
 These sensors are connected across network through Wi-Fi under IEEE standard
802.11 b/g/n makes more relevant and valuable ever than before .
 By turning sensor information into actions, real time data from mining
environment can be monitored and controlled remotely from anywhere..
 The information can be monitored through an ISO android app and personal
computers remotely.

5. Sensors Used
Temperature sensor
Humidity sensor
Ultrasonic sensor
Motion sensor
Gas sensor
Sound sensor
RFID
Emergency panel
Notification Panel

6. Needs
 Wearing smart safety jacket is
necessary
 He should be remotely monitored
and traced continuously to keep
him safe
 Free from Health Hazards
 Best Communication technology
 Only those who are wearing the
smart safety jacket should be
allowed at the site.
Goals
 By trapping real time data and allow
adjustments to be made before anything
can go wrong.
 Reduce the risk associated with every
step of the mining process.
 Monitor each and every miners in mining
environment by providing Smart Safety
Jacket for each miners
 To alert miners in case of hazards .
 Work in a safety, comfort and efficient
environment.

8. Gas sensor (MQ4,MQ7)
 MQ4
Features:
 High sensitivity to CH4，Natural
gas, smoke
 Fast response, Stable and long life
Sensitivity characteristic:
 Detecting concentration scope
200-10000ppmn CH4 , natural
gas
 MQ7
Features:
 High sensitivity to carbon monoxide
 Fast response, Stable and long life
Sensitivity characteristic:
 Detecting range 20ppm-2000ppm carbon
monoxide

9. Emergency Panel
 In Case of any emergency if miner press the emergency
button on Smart Safety Jacket the logic changes from 0 to
1 and sends notification to control room that the
particular miner is in danger.
Ultrasonic sensor(HC-SR04)
 An OBSTACLE AVOIDING SYSTEM is the one which can avoid
an obstacle by using ultrasound sensor which is necessary
to avoid accidents in mining area due to moving vehicle
and huge rocks.
 Ultrasonic ranging module HC-SR04 provides 2cm - 400cm
non-contact measurement function, the ranging accuracy
can reach to 3mm.

10. Motion sensor(Accelerometer ADXL335)
 The ADXL335 is a small, thin, low power, complete 3-axis
accelerometer with signal conditioned voltage outputs. The product
measures acceleration with a minimum full-scale range of ±𝟑𝐠 . It
can measure the static acceleration of gravity in tilt-sensing
applications, as well as dynamic acceleration resulting from motion,
shock, or vibration.
Notification Panel
 This sensor ensures and provides notification in case of any collapse
or earthquake by fetching data continuously from database of
vibration sensor section. If values in database exists the threshold
level then notification will be provided by means Of LED blink , Loud
Buzzer or Vibrator

11. RFID(radio frequency identification)
 Technology that incorporates the use of
electromagnetic or electrostatic coupling
in the radio frequency (RF) portion of the
electromagnetic spectrum to uniquely
identify an object, animal, or person.
 The unique identification can be done by
providing each miner with RFID tags. When
a worker enters a unsafe zone a buzzer
starts buzzing automatically .The software
is also alerted so management knows the
situation.

12. Sound Sensor
 Prolonged exposure to loud noise can cause permanent damage
to the auditory nerve and/or its sensory components. When
the sensor detects a sound that exists the threshold level, it
processes an output signal voltage which is sent to a
microcontroller then performs necessary processing and
provides notification
Temperature and Humidity sensor (DHT11)
 DHT11 Humidity sensor
Features:
 Measurement Range 20-90% RH
 Humidity Accuracy ±5％RH
 DHT11 Temperature sensor
Features:
 Measurement Range 32-122°F
 Temperature Accuracy ±35.6 °F

13. Microcontroller ESP8266-12
 ESP-12E Wi-Fi module is developed by Ai-thinker Team. core
processor ESP8266 in smaller sizes of the module
encapsulates Tensilica L106 integrates industry-leading ultra
low power 32-bit MCU
Features:
 Supports IEEE 802.11 b/g/n
 Integrated low power 32-bit MCU
 Integrated 10-bit ADC
 Integrated TCP/IP protocol stack
 Wi-Fi 2.4 GHz, support WPA/WPA2
 SDIO 2.0, (H) SPI, UART, I2C, I2S, IRDA, PWM, GPIO
 Operating temperature range -40C ~ 125C

14. Alerting System
 Alerting miners in mines can be a difficult process .The
underground are very dark place and equipment’s used in
underground mines can create lots of noise and vibration.
 So the best way of alerting the miners is flashing the LED
on smart safety jacket .Flashing the light constantly and
simultaneously can show who is experiencing the problem.

15. Servers used
wamp server GlassFish Server
 Apache as Web server
 MySQL database
 Scripting languages PHP
 GlassFish Server for Java
Database Connectivity
 Method : Java Server pages

16. Miners Monitoring Process
 Monitoring process can be carried out in two ways by developing
Web application for monitoring miners from personal computers
and laptops etc.. Similar an android app has been developed for
monitoring miner from smart phones.
 Work allocation can be done according to the requirement and
tracking of each and every miner can be done using developing
WEB and Android apps.
 The person who is monitoring miners in mining area has
responsibilities to take right action in right time for protecting
miners from various hazards.
