Coder in Action 2021 | First Place Winner “Zelzele1.0”

Sep 14th, 2021 – Written by Idris Ibrahim Erten

I would like to introduce our project called “Post-earthquake audio transmission system ZelZele v1.0”. It has been developed to minimize the damage of earthquake disasters that have been occurred in recent years, which have previously caused severe losses in the Elazig, Malatya, and Aegean Sea regions.

We thought about this project to minimize the damage of the Istanbul earthquake expected in our country. Although we prioritized using the device in our country, its design and software have been developed by following international standards.

Our project contains two separate devices as a receiver and a transmitter. There are also sensors that detect earthquakes and activate the system besides transceiver systems. I believe our product is a serious candidate for creating a solution to an earthquake disaster with its capabilities. 

Installation and use of the device

When the installation of our device is requested in the planned living space, it can be placed on each floor without requiring a specific area in the building. After providing an electrical connection by a power source, it will become compatible with artificial intelligence, based directly on the area without any adjustments.

This system is environmentally friendly with low energy consumption and rechargeable many times. Our product can work without any problems for many years with a 12V adapter integrated with the charge control system located on it until the moment of possible earthquakes. 

It operates with charged battery after activation. It can offer a minimum of 48 hours of use without a limit according to the maximum battery capacity. Our product works with an electrical connection until the moment of a possible earthquake.

 It is proven to be preferred under the conditions of our country today with minimum electricity consumption of 0.80 cents per 7 days and environmental friendliness. Our project is designed on sound transmission with a frequency determined from underground to above ground. Also, with a specific sound transmission system, one on the outside and one on the inside.

The receiver part of our device is activated directly during an earthquake. In the case of debris, it is easy to switch to the communication state. The system activates when it receives a signal with a special frequency or a communication card. It is possible to send sound from here as well as from the inside. 

What data does this device receive and give to us? 

First of all, it can get information about how strong the earthquake occurred in an area, also, how many seconds of destruction occurred after the shake.

It can also get information about the severity of the last tremor before the demolition. It can make it easier to map the location of transmitters sending information using machine learning. We call the black box of the building assembled for the buyer.

The transmitter part

Our transmitter part has a lot of responsibility because it transmits information from the area where it is assembled. This part was also developed with a microphone which is a great fit for electronic parts. This microphone can easily receive even the smallest sounds in the environment. It has a powerful speaker on it that allows us to hear sounds from special frequency, and people trapped under the rubble can easily hear those talking from outside. That makes it decidedly easier for search and rescue teams to intervene while they are feeling safe. 

Earthquake sensor six-axis gyroscope sensor and specially prepared software are available together with this sensor and software. These are both using machine learning to interpret aftershocks and predict large earthquakes in October. It facilitates mapping with height detection within both 6 October and November. Also, with earthquake prediction, a siren can sound in an emergency or during an earthquake, if desired. 

The sensor image detects the moment of shaking. Our device detects during an earthquake and, we are receiving it from outside.

 Project Development Goals

* Make the map of ground movements in the areas where the assembly was performed, with a display connection suitable for daily use, such as recent earthquakes.

* GPS / LOCAL WIFI tests and mapping creation and visualization work as a result of tests.
