求翻译：按照物联网的产业链大致可以分三个层面：首先是传感网络，以二维码、RFID（射频识别技术）、传感器、芯片及智能卡为主，实现“物”的识别；其次是传输网络，通过现有的互联网、广电网络、通信网络等实现数据的传输与计算；三是应用网络，即输入输出控制终端，可基于现有的手机、PC等终端进行。是什么意思？

According to the chain of things can be roughly divided into three levels: first, sensor networks, two-dimensional codes, RFID (radio frequency identification technology), sensors, and smart card chip-based, and "objects" of the identification; followed by the transmission network through the existi
