運用無線閘道器實現感測網路

本論文主要是透過無線閘道器、射頻收發模組和感測器節點設計出一套無線感測網路系統，再透過此系統設定微控器的輸入輸出腳位分別跟感測器和網路系統做個整合，達成感測器與雲端上面進行溝通的橋梁。此嵌入式系統之開發與研究最大的目的是為了迎合現代和未來的科技產品走向去考量與設計，由於智慧型手機和平板電腦的普遍與發達，一般都具備上網功能，透過Wi-Fi連接本系統查看感測網路的動態；網路模組與射頻傳輸系統整合最大的目的就是以最低的成本形成一個區域的網路，例如一般的家電用品要達成利用Wi-Fi網路進行無線溝通，只需要安裝低成本的射頻傳輸系統，所以此通訊系統的開發不但可以使用在無線感測網路，其他使用也包含物聯網、智慧家庭、工廠監控、智慧電網和醫療照護等。論文主要分為三大主軸，一是利用8位元微控器和Kaise公司提供MQ-5氣體感測器模組形成一個感測節點；二是使用8位元微控器和Nordic公司提供nRF24L01射頻收發模組實現無線射頻傳輸系統；三是運用32位元的微控器和Microchip公司提供MRF24WB0MA之Wi-Fi晶片達成無線閘道器系統架構，最後再與無線射頻系統、感測器做整合，以實現感測網路。

This thesis provides a design of a wireless sensor network by wireless routers, RF transceivers and sensor nodes. To communicate with the cloud service, the microcontroller of the sensor node needs to attach to network interface as well as sensors. The major purpose of this embedded system research is to follow the current and future trend of the electronic gadgets. Common smartphones and tablets can connect to our sensor network via Wi-Fi. The main reason of integrating TCP/IP network with RF transceivers is to form a local network using minimum cost. For example, we can simply put a low-cost RF transceiver to let home appliances connect to the Internet. Therefore, this interconnection system can apply to not only the sensor network, but also IoT, smart home, factory monitoring, smart grid, medical care, and so on. Paper mainly contain three main part, first using 8-bit Microcontroller and Kaise’s MQ-5 gas sensor module to build Sensor nodes, second using 8-bit Microcontroller and Nordic’s nRF24L01 RF Module to achieve RF transmission system; third using 32-bit Microcontroller and Microchip’s MRF24WB0MA Wi-Fi chip to accomplish Wireless gateway system architecture, finally Integrate RF systems with Sensor nodes to achieve Sensor Networks.
