物聯網是指讓許多的物件透過各種方式來進行溝通並應用於各種環境偵測。智慧環境的控制為物聯網主要的應用之一，隨著科技的進步，許多的家電設備被研發出來服務人們，而對於這些高異質性的單項設備來說，要如何建構一套系統，可以讓使用者簡單的串聯設備，使其能自動化並相互溝通是一個重要的議題。
在這個過程中主要的問題是需要先克服各種異質性物件的溝通障礙，本論文中將會提出利用商業流程建模與符號BPMN與Activiti流程管理工具來整合異質性物件方法，讓使用者可以使用Activiti進行編輯與執行流程，使流程與設備能互相溝通。在硬體方面我們使用硬體中央管理器Raspberry Pi進行串聯設備，其將會根據流程需求來賦予各個設備任務與服務。
透過這些方法，系統將能自動化的對應各種室內環境條件，來控制家電或設備，使室內達到舒適且安全的環境，有助於人員的理解與維護，可以更簡單、快速的修改編輯流程，並達到彈性整合異質性物件。

The Internet of Things (IOT) means that many objects are connected in various ways and applied to detect various environmental conditions. The control of the ambient intelligence is one of the main topics of the IOT applications. With the advancement of technology, many home appliances have been developed with communication capability. For these highly heterogeneous devices, how to connect them together to construct a system which can be automated and communicated with each other is an important issue. The main problem of this task is to overcome the communication barriers of various heterogeneous objects. In this study, the Business Process Model and Notation (BPMN) and Activiti process management tool are applied to integrate these heterogeneous objects and allow users to use Activiti for editing and execution processes, so that processes and devices can communicate with each other. To demonstrate that the proposed method is feasible, an indoor environment monitoring system is implemented to monitor the comfortability and safety of indoor environment.
