In this project, it is aimed to put an end to the mine accidents that many people have ended in death, which is happening in Turkey and in the world, to predict and prevent possible accidents. In the study, a wristband was designed for the miners, aiming to measure the gas rates in the mine, to continuously monitor the health status of each miner and to determine the positions of the miners in case of a dent. #SciChallenge2017

Mine-Miner Searching, Detecting and Saving System (M-MATEKS) #SciChallenge2017

  1. 1. Tuluğhan Çivioğlu - Muhammet Yusuf Alkuş Kartal Anatolian Imam Hatip High School 11-IB
  2. 2. Table-I Major mining accidents in the last decade When the report of the Union of Turkish Engineers and Architects in Table 1 on the mining accidents in 2014 is examined, it is seen that about 1000 miners have lost their lives in the last 10 years. There are two major reasons for these mining accidents. One of these reasons is the explosion of the gris, and the other is the fire. It will be overcomed by this project, M-MATEKS.
  3. 3. It is aimed to predict and prevent the ongoing mining accidents despite the fact that many studies have been done in this work which is done by way of the literature study and which is made continuously in our country and in the world.
  4. 4. It has been seen that after the study of M-MATEKS, which was passed on after the increasing mining accidents, the literature was not designed before. With M-MATEKS, it is aimed to close this gap. This work;  Wristband design  The design of the mine that the wristband will provide maximum efficiency to human beings  Interface design will be examined in three main sections.
  5. 5. Wristband design; 1. The area where the carbon monoxide gas sensor is located 2. The region that will allow the methane gas sensor to receive data from the media 3. The zone that will allow the heart rate sensor to receive data from the media 4. Protective cap 5. The area where the Bluetooth module and Arduino-Nano will be found Although many materials are used in the wristband, the weight of the wristband is approximately 125 grams and the miner's normal working tempos is not Figure-I Bracelet design
  6. 6. The heart rate sensor uses four basic technical components to measure heart rate: I. Optical Transmitter Optical transmitters are made using LEDs. These LEDs are responsible for sending light under deep. The blood stream dissipates this incoming light and the instrument measures the distribution of this light. II. Digital Signal Processor (DSP) The digital signal processor collects the light reflected back by distributing the blood flow, and gives the output in the form of 1 and 0 to get meaningful heart rate data. III. Accelerometer Accelerometer is an instrument for measuring motion. In the pulse sensor, it measures blood motion and works in cooperation with the digital signal processor to help achieve more accurate results. IV. Algorithms The algorithms process motion-tolerated heart rate data Figure-II Heart Rate Sensor
  7. 7. The sensors can measure up to 10000 ppm. These sensors output an analog voltage output according to the density of the gas. The measurement of methane gas, one of the biggest causes of the explosion of the glaze that may be experienced in the mine, allows us to prevent these explosions. The use of this sensor will have a vital proposition when it is thought how lethal the carbon monoxide gas produced by the fire is.Figure-III MQ-4 and MQ-7 Sensor
  8. 8. The HC-05 Bluetooth module used is for wireless serial communication applications. It is easy to use with the help of pins on it. Provides communication at 2.4GHz frequency. The indoor area has a communication distance of about 10 meters. Figure-IV Bluetooth Serial Module
  9. 9. In order to be able to study the design and the planned system, a new mine structure was uncovered without much change in the mines. The mine is equipped with a bluetooth serial module in boxes made of stainless steel every five meters. In order to exchange data, Arduino-Nano has installed necessary codes using C and C ++ language.
  10. 10. Figure-V Mine design In mine design, The data from gas sensors and pulse sensors located on the bracelet designed for the miner are transferred from bluetooth in the wrist strap to bluetooths placed every five meters to the mine ceiling. These bluetooth devices transfer the data to distributors located every 30 meters on the mine ceiling. The distributors transfer the received data to the data processing center. Data is transferred instantaneously on the follow-up panel in the data processing center. The data coming from this panel are examined and evaluated by the staff. If the pulse of the madder falls, the gases in the environment are raised above the specified ratios, and the emergency button is pressed, the background of the program in the data processing center turns red and an "Emergency" warning is displayed. Observations of such a situation will result in the implementation of the necessary emergency protocols. At the time of a dent, the location of the miner is determined by determining which floor and where the miner data comes from the Bluetooth, and the search
  11. 11. It is understood that the data coming to the data processing center that the miner's wristband is working on. The transmission of the pulse, carbon monoxide, methane and position data of the miner is provided by the communication between the wristbands and the bluetooths on the pan. When any of the miners that appear in the program are selected, the data of the selected miner will be displayed in graphical form in the program at the data processing center.
  12. 12. Experiment Part of the Project: The school, which is used as an alternative mine environment, consists of of 4 kats. On the 4th floor there is a data data processing center. Ten students selected from school students were distributed to different areas of the school, and each person selected for the the experiment was wearing a wristband. wristband. The data read by the pulse, methane and carbon monoxide sensors sensors on the wrist has been transferred transferred to the data processing center center via the established system. As experienced in the experiment, the data data received from the miners thanks to Madencinin Adı- Soyadı Nabız Verileri Metan Verileri Karbonmonoksit Verileri Konum Verileri Madenci-1 87 bpm 272 ppm 27 ppm 2.

  14. 14. As seen from the experiments, the prototype of the device and the inside of the mine are instantly controlled at the data processing center of the mine's pulse and position information. The transmitted data was evaluated by the staff at the data processing center. In the event of an emergency, the necessary emergency procedures were carried out, the fans were operated automatically and the necessary actions were instantly implemented via personnel via M-MATEKS.
  15. 15. In the literature study, it is seen that there are few projects about this sector. These projects have been understood from the wreckage that some parts are very costly and the other parts are useless. Therefore, M-MATEKS, which is inexpensive, sensitive, programmed and feature-rich with its cost, is going to prevent the continuous mining accidents in the world.
  16. 16. Also;  M-MATEKS can work with other systems at the moment of dent.  In an unlikely event, the fans will work to reduce the dangerous gas concentration in the environment.  The data is processed automatically in the data processing center.  All transactions are made with BlueToths and wireless communication is provided. With the support to be given, it is aimed that the project has a more aesthetic structure, its application and dissemination in the mines.
  17. 17.  Experiments can not be performed due to lack of suitable environment, real environment of the mine can be done if the system is applied in real mine.  Further experimentation can increase the sensitivity level of the system.  The wristband can be made more functional by adding sensors other than carbon monoxide, methane sensor, and a smaller design can be made.  Instead of putting too much bluetooth on the ceiling of the mine, the shooting area could be wider NRF, Bluetooth 4.0, Xbee module, but Bluetooth 2.0 was used in the project because the cost is at least when Bluetooth 2.0 is used.
