在網路通訊基礎設施和雲端服務系統愈趨完備下，全球物聯網市場規模進入高成長的時代，公司行號可藉由物聯網來提升公司營運效率或更佳的了解客戶，以提供更好的服務品質。而微控制器具有體積小、低功耗及低成本的優勢，所以可利用微控制器開發物出電梯物聯網。在施行的計畫上，硬體使用32位元ARM Cortex-M系列微控制器做為嵌入式系統的核心，搭配無線通訊元件;軟體則使用C/C++語言及ARM Mbed OS生態系統做為開發平台，藉由MQTT輕量級的訊息傳遞協議，加上傳輸層安全性協定（TLS）為通訊訊息進行加密，來達成利用物聯網遠端監測電梯的目的，這使得我們能從遠端螢幕即時監控電梯的狀態或得知電梯發出的故障警示，進而能清楚且快速做出決策，這便是電梯物聯網所帶來的價值。;The global Internet of Things (IoT) market size moves to high growth era when the coming infrastructure and cloud service built more completely. Organizations can use the IoT to improve company operating efficiency or better understand customers to provide better service quality. Microcontrollers have the advantages of small size, low power consumption and low cost, so we can use microcontrollers to develop elevator IoT. The implementation plan is that the hardware uses a 32-bit ARM Cortex-M series MCU as the core of the embedded system, with a wireless communication element. The software uses the C/C++ language and the ARM Mbed OS ecosystem as the development platform. By using MQTT lightweight messaging protocol and transport layer security protocol (TLS) to encrypt communication information to achieve the purpose of remote monitoring elevator using the Internet of things. So we can see the elevator status or fault alerts in real time from a remote screen. That helps us make clear and quick decisions about what to do for next step. This is the value brought by the elevator Internet of things.
