Abstract

Güvenlik günümüzde en önemli sorunlardan birisidir. Kişilerin artan iş yükleri ve gündelik programlarının yoğunluğu yaşadıkları kişisel alanların güvenliklerini sağlamalarını zorlaştırmaktadır. Bu nedenle çoğu insan mesken ve ofislerine güvenlik sistemi oluşturma ihtiyacı hissetmektedir. Birçok akıllı ev sistemine dâhil edilmiş güvenlik sistemi bulunmaktadır. Akıllı güvenlik sistemleriyle özel mülke izinsiz girişleri takip edebilmekle birlikte gaz kaçağı, su baskını, yangın, deprem vb. gibi birçok durumdan uzaktan haberdar olunabilmektedir. Bu çalışmada düşük maliyetli GSM tabanlı bir ev güvenlik sistemi tasarımı yapılmıştır. Tasarım modüler bir yapıda ve genel amaçlı kullanıma uygun bir şekilde gerçekleştirilmiştir. Tasarlanan donanımda geniş voltaj aralığında analog ve dijital sinyal okuyabilecek girişler ve kuru kontak röle çıkışları mevcut bırakılmıştır. Böylece birçok sensor ya da aygıtın bu donanım ile birlikte kullanılabilmesi sağlanmıştır. İnsan vücudunun gözle görülemeyen kızılötesi formda bir miktar ısı enerjisi ürettiği olgusundan yola çıkılarak algılama ve alarm ve uyarı sistemi oluşturulması amaçlanmıştır. Tasarımda maliyeti etkileyecek en önemli malzemeler olan işlemci ve GSM modülün modüler olarak ayrı bir kartta toplanması sürekli artarak değişen malzeme fiyatlarına karşı hızlıca değişim yapabilme imkanı sağlaması bu çalışmanın özgün yanını oluşturmaktadır. Tasarımın sade olması ucuz bir işlemci ve GSM modül kullanılabilmesine imkân sağlamıştır. Ayrıca modüler yapı sayesinde fiyat artışlarında ya da 2G’den 4G’ye geçiş gibi teknolojik değişmelerde hızlıca dönüştürülebilir bir tasarım geliştirilmiştir. Bu çalışmanın ana senaryosu güvenlik sisteminin kurulduğu alanda ihlal algılandığında GSM alt yapısı kullanılarak ihlal durumunun belirlenmiş noktalara bildirilmesi şeklinde oluşturulmuştur ve düşük maliyetli bir tasarım olması ön planda tutulmuştur.

Low Cost GSM Based Home Security System

Abstract

Security is one of the most important issues today. Increasing workloads of people and the intensity of their daily schedules make it difficult for them to ensure the security of their personal areas. For this reason, most people feel the need to create a security system for their residences and offices. Many smart home systems have security systems built into them. With its smart security systems, it is able to monitor unauthorized access to private property, as well as gas leakage, flood, fire, earthquake, etc. It is possible to be aware of many situations such as remotely. In this study, a low-cost GSM-based home security system was designed. The design has been carried out in a modular structure and suitable for general purpose use. In the designed hardware, inputs and dry contact relay outputs that can read analog and digital signals in a wide voltage range are available. Thus, it has been ensured that many sensors or devices can be used with this hardware. It is aimed to create a detection and alarm and warning system based on the fact that the human body produces some heat energy in invisible infrared form. The fact that the processor and GSM module, which are the most important materials that will affect the cost in design, are modularly collected on a separate card and that they provide the opportunity for rapid change against the ever-increasing material prices constitute the original side of this study. The simplicity of the design allows the use of an inexpensive processor and GSM module. In addition, thanks to the modular structure, a rapidly transformable design has been developed in case of price increases or technological changes such as the transition from 2G to 4G. The main scenario of this study was created in the form of notifying the violation status to the determined points using the GSM infrastructure when a violation is detected in the area where the security system is installed. The low cost criterion was prioritized in the design.
