Abstract:One of the most important factors for successful agricultural production is the irrigation system in place. In this study, a precision irrigation system, which takes advantage of the various phases of plant growth, was developed and implemented using the sensor network technology integrated with IOS/Android. The amount of water in the soil was measured via sensors that were placed on certain points of the area to be irrigated. These sensors were placed near the root of the product. Data from sensors was transmitted via Wi-Fi in real-time to a mobile phone based on IOS/Android. In the light of obtained data, the seasonal precision irrigation system was created depending on the amount of water required by the plants at each stage of their growth stage. The required energy of the system was provided by solar energy. The system can be controlled by smart phones, which increases the usability of the system. When design performance was analyzed, it was observed that some important advantages such as obtaining high efficiency with water, time and energy saving and reducing the workforce were ensured. Five separate laterals were used for the irrigation system. There were valves on each lateral, which realized the opening and closing process depending on the water need. A total of 16 humidity sensors were used in the irrigation system and the data from these sensors was transferred to the IOS/Android server via the programmable controller (PLC). The basic electrical equipment in the irrigation system was monitored and controlled via mobile devices. Control parameters were obtained by comparing the real values and reference values by a closed-loop system and determine the new working status of the irrigation system.
Özet-Bilgi teknolojileri altyapısının gelişmesi ve geniş coğrafi alanlara yayılması bireylerin, toplumların, kurumların ve devletlerin birbirleri ile olan ilişkilerini iletişim ve bilgisayar ağları üzerinden yürütebilmelerine olanak sağlamıştır. Günümüzde yaklaşık 2 milyar insan internet kullanmaktadır ve Microsoft'un araştırmasına göre bu sayının 2025 yılına kadar hızla artarak 4 milyarı geçmesi beklenmektedir. Kullanıcı sayısı arttıkça genel tanımlama ile -Siber Güvenlik‖ olarak adlandırdığımız problem ortaya çıkmaktadır. Artık ülkeler kendi bilgi sistemlerini ve kritik altyapılarını bilgi teknolojileri altyapısıyla oluşturmaktadır. Ancak, bu sistemlerin korunması için de yine bilgi teknolojileri altyapısı kullanılmakta ve bir kısır döngü oluşmaktadır. Ülkeler siber alana bağımlı olan sistemlerini siber tehditlere karşı korumak için standartlar, politikalar ve stratejiler geliştirmiş ve uygulamıştır. Bu çalışmada teknolojinin gelişmesiyle birlikte küreselleşmeye bağlı güvenlik kaygılarının ortaya çıkışı, ülkemizde uygulanan bilgi toplumu stratejisi, ülkemiz ve dünyada bilgi toplumuna geçiş süreci, bilgi teknolojileriyle oluşturulan kritik altyapı sistemleri, bu sistemlere karşı siber tehditler ve bu sistemlerin risk analizi incelenmiştir. Anahtar Kelimeler-Siber güvenlik, Bilgi toplumu, Kritik altyapılar Transition to Information Society and Cyber SecurityAbstract-Improving of information infrastructure technologies and expanding to broad geographical areas; enable persons, societies, institutions and states communicates with the help of communication and computer networks. Nowadays, approximately 2 billion people use internet and according to Microsoft search, passing to 4 billions is hoped till 2025. With increasing of users quantity, generally of privately -Cyber security‖ problem comes up. Now countries use information technologies while constituting own information system and critical infrastructure. But for the protection of these systems still in use in information technology infrastructure and there occurs a vicious circle. Countries of the system to protect against cyber threats that are dependent on cyber field, standards, policies and strategies developed and implemented. In this study, the emergence of globalization depends on security concerns with the development of technology, information society strategy applied in our country, the knowledge society transition period in our country and around the world, critical infrastructure created by information technology, cyber threats against the system and risk analysis of these systems examined.
