基于射頻識別的無線傳感網(wǎng)節(jié)點設(shè)計

　　為了解決無線傳感網(wǎng)通常運行在人不能或不便接近的環(huán)境，能源無法替代的問題，該設(shè)計采用了單片機MSP430F2370芯片和少量外圍電路等來構(gòu)成完整測量系統(tǒng)。由于其充分利用了單片機內(nèi)部資源，使系統(tǒng)硬、軟件設(shè)計達到了最小化，具有識別可靠性高、抗干擾能力強、成本低廉和體積小巧等特點。它可以識別ISO15693，ISO14443A，ISO14443B等多種協(xié)議標(biāo)準(zhǔn)的電子標(biāo)簽。在今后的門禁系統(tǒng)、生產(chǎn)線檢測、自動收費系統(tǒng)、超市物流等方面有很大的應(yīng)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.
