RFID technology is radio frequency identification technology. It is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various a hostile environment. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient. RFID is divided into low frequency (LF), high frequency (HF), ultra high frequency (UHF), and microwave (MW) according to the frequency of use. The corresponding representative frequencies are: low frequency below 135KHz, high frequency 13.56MHz, ultra High frequency 860M～960MHz, microwave 2.4G, 5.8G. RFID technology is currently widely used in applications such as logistics and supply management, manufacturing and assembly, airline baggage handling, mail, express package handling, document tracking, and library management animal identification.

自动化物流分拣是先进配送中心所必需的设施条件之一，它具有很高的分拣效率，通常每小时可分拣商品6000-12000箱。可以说，自动分拣机是提高物流配送效率的一项关键因素。它是二次大战后在美国、日本等发达国家的物流中心中广泛采用的一种物流分拣系统，目前已经成为发达国家大中型物流中心不可缺少的一部分。自动分拣系统一般由控制装置、分类装置、输送装置及分拣道口组成。控制装置的作用是识别、接收和处理分拣信号，根据分拣信号的要求指示分类装置、按商品品种、按商品送达地点或按货主的类别对商品进行自动分类。这些分拣需求可以通过不同方式，如可通过条形码扫描、键盘输入、重量检测、语音识别、高度检测及形状识别等方式，输入到分拣控制系统中去，根据对这些分拣信号判断，来决定某一种物品该进入哪一个分拣道口。Automated logistics sorting is one of the necessary facilities for advanced distribution centers. It has high sorting efficiency and can usually sort 6000-12000 boxes of goods per hour. It can be said that the automatic sorting machine is a key factor to improve the efficiency of logistics distribution. It is a logistics sorting system widely used in the logistics centers of developed countries such as the United States and Japan after World War II, and has become an indispensable part of large and medium-sized logistics centers in developed countries. The automatic sorting system generally consists of a control device, a sorting device, a conveying device and a sorting crossing. The function of the control device is to identify, receive and process the sorting signal, instruct the sorting device according to the requirements of the sorting signal, and automatically classify the goods according to the type of goods, the delivery location of the goods or the category of the owner. These sorting requirements can be input into the sorting control system in different ways, such as barcode scanning, keyboard input, weight detection, voice recognition, height detection, and shape recognition. Based on the judgment of these sorting signals, the Decide which sorting crossing a certain item should enter.
