基于射频识别的无线传感网节点设计

　　为了解决无线传感网通常运行在人不能或不便接近的环境，能源无法替代的问题，该设计采用了单片机MSP430F2370芯片和少量外围电路等来构成完整测量系统。由于其充分利用了单片机内部资源，使系统硬、软件设计达到了最小化，具有识别可靠性高、抗干扰能力强、成本低廉和体积小巧等特点。它可以识别ISO15693，ISO14443A，ISO14443B等多种协议标准的电子标签。在今后的门禁系统、生产线检测、自动收费系统、超市物流等方面有很大的应用前景。

　　Abstract:

　　In order to solve the problems that the wireless sensor network often runs in the environment that the person cannot or inconveniently approach and the power is irreplaceable，this design adopts a single-chip microcomputer MSP430F2370 and a small amount of buffer circuit to compose a complete measuring system. It fully utilizes internal resources of the microcontroller，which makes the system?蒺s hardware and software design minimized. It has characteristics of reliable identification，strong anti-jamming capability，low cost and compactsize. It can identify the various protocol standard electronic tags，such as ISO15693，ISO14443A，ISO14443B etc. It will have great application prospect in the entrance guard system，production line detection，automatic charge system，and supermarket logistics aspects.
