國內於2017年由部分電信商及科技公司正式推出NB-IoT服務,並逐步被各界市場接受,其長距離、低功耗與蜂巢式設計亦適於農業的應用。NB-IoT應用在被各界市場接受,但作為授權頻段的傳輸技術,需向電信公司申請月費方案使用,而LoRa傳輸技術雖不需要向電信公司申請使用,但由於其系統架構下,需搭配其他傳輸技術藉由閘道將資料傳出,通常是搭配Wi-Fi傳輸技術。 本論文於建置農地監控中,針對沒有Wi-Fi環境的場域建立一套結合NB-IoT及LoRa傳輸技術,將探測端點所收集到的資料由NB-IoT傳輸出去,與閘道取得時間戳記,針對封包掉落以及硬體出問題的情況提出重傳機制、故障通知。
In 2017, NB-IoT services were officially launched by some telecom operators and technology companies in Taiwan, and gradually accepted by various markets. Their long-distance, low-power and cellular design are also suitable for agricultural applications. The NB-IoT applications are accepted by various markets, but as a transmission technology of the licensed frequency band, it is required to apply to the telecommunications company for the monthly fee scheme. However, the LoRa transmission technology does not need to apply to the telecommunications company, under the system architecture, it is necessary to use other transmission technologies to transmit data through the gateway, usually with Wi-Fi transmission technology. In this thesis, the construction of agricultural land monitoring, a set of NB-IoT and LoRa transmission technologies are established for the field without Wi-Fi environment, and the data collected by the detection endpoints is transmitted by NB-IoT and obtained with the gateway.
