本論文實現做出一種手機APP與車輛環境狀態監測結合，利用MQTT協定進行資料傳遞與實現手機APP推播功能。系統主要有三個功能，分別為環境監測、車輛意外通知與車輛上鎖監控警示。
在環境監測功能中，系統會透過感測器收集車子內部資訊，收集出車內溫度、濕度、危險氣體含量、行車速度與車子所在位置，經由MCU整合資料後，上傳資料至雲端服務空間儲存，使用者可以透過手機APP查詢雲端服務空間所儲存的車子內部資訊。在車輛意外通知裡，車子在行駛中發生碰撞意外，系統會自動偵測出，並透過MQTT傳遞資料至手機APP，手機APP會產生推播通知告知外界，推播通知中除了告知車子發生意外也會包含了車子所在位置，有效的縮短救援等待時間。在車輛上鎖監控警示中，駕駛下車後，可使用手機APP透過MQTT傳遞資料至系統，開啟車門監控警示，開啟車門監控警示後，如果車門開啟，系統會透過MQTT傳遞資料至手機APP，手機APP會產生推播通知，以用來通知駕駛人與駕駛家人，以防止車子被竊風險。

This thesis realizes a combination of the mobile phone APP and vehicle environmental condition monitoring, uses MQTT protocol to transmit data and implement the mobile phone APP broadcasting function. The system provides three main parts including environmental monitoring, vehicle accident notification, and vehicle locking monitoring.
In the environmental monitoring, the system first collects the internal information of the car through sensors that including the temperature, humidity, dangerous gas, vehicle speed, and the location of the vehicle. Afterward, the system uploads the internal information to the cloud storage.
In the accident notification, the system will automatically detect and send data to the mobile phone APP through the MQTT if the collision of the vehicle occurred. Besides, the mobile phone APP will generate push notifications to inform the outside world. In addition to informing the car about accidents, the push notification also includes the location of the car in order to reduce the waiting time for rescue.
In the vehicle lock monitoring warning, after driving off, you can use the mobile phone APP to transmit data to the system through MQTT to open the door monitoring alert. If the door is opening, the system will transfer data to the mobile phone APP via MQTT. At the same time, the Push notifications will be generated to inform drivers and driver families.
