مقدمة: نستخدم بطاقة RFID شائع جداً الآن, ولكن تعرف تفاصيل هذه التكنولوجيا? الأساس لتقنية RFID لاستخدام الطاقة الكهرومغناطيسية, طاقة موجودة في الطبيعة, لتحقيق أيدك.
الناس ’ s فهم الطاقة الكهرومغناطيسية:
تاريخ يعود إلى اكتشاف واستخدام المغناطيس الطبيعي في قبل الميلاد., الصين. People used magnets to make compass Chariot(عربة مشيراً إلى جنوب). In modern times, more and more people dedicated their life in the study of electricity, المغناطيسية, الضوء, as well as basic mathematics research. بنجامين فرانكلين كان الأكثر شهرة من بينها أمريكا. في 1846, the British scientist Michael Faraday discovered that light waves and electromagnetic waves both belong to electromagnetic energy. في 1864, the Scottish scientist James Clerk Maxwell declared to the world his electromagnetic theory.
في 1887, the German scientists Heinrich Rudolf Hertz proved the electromagnetic theory of James Clerk Maxwell and demonstrated that electromagnetic waves could spread at the speed of light and could be reflected with the polarization characteristic of light. The experiment of Hertz was repeated by the Russian scientist Alexander Pope. في 1986, Guglielmo Marconi sent successfully the transatlantic telegram. It was the first time to use electromagnetic energy to serve humanity. في 1922, Radar appeared. As an effective weapon to identify enemy’s flying objects(aircraft), Radar played an important role in the Second World War. Everyone also knows that radar used by the Royal Air Force played a decisive role in the battle against the German Air Force. ولذلك, radar technology got great development. الآن, the radar technology continues to advance. People are developing high-performance radars for various applications. RFID inherits the concept of radar and this has led to the development of AIDC technology. في 1948, Harry Stockman published his “الاتصالات عن طريق الطاقة المنعكسة” and this article is the basis of RFID technology.
في القرن العشرين, البحوث المتعلقة بنظرية وتطبيق التكنولوجيا اللاسلكية واحدة من أهم الإنجازات التي تحققت في تطوير العلوم والتكنولوجيا. Following are the تطوير تكنولوجيا RFID:
- 1941-1950 وادي تطبيق الرادار إلى اختراع RFID. في 1948 appeared the theory basis of RFID technology.
- 1951-1960 The early exploration of RFID technology, أساسا في التجارب المعملية.
- 1961-1970 The theory of RFID technology achieved great development and scientists began to do some application attempts.
- 1971-1980 فترة من التنمية لتتفاعل. Various RFID tests were accelerated. ظهرت بعض التطبيقات التي تتفاعل أقرب.
- 1981-1990 RFID technology and products enter the stage of commercial application.
- 1991-2000 The standardization of RFID technology has become increasingly important. RFID products are widely used in daily life, and RFID products have gradually become a part of people’s life.
Later we’ll talk about several important progress of RFID technology in modern history. Please look forward to our next article.
