碩士 === 國立中央大學 === 資訊工程學系在職專班 === 105 === In order to shorten response time without compromising the confidentiality of private data, fog calculation or marginal computing has become a new research topic, in the post-cloud era, the traditional network of objects with cloud computing being the core will face difficulties in meeting the standard of the real-time terminal services with limited bandwidth. This study designed a network of objects gateway with three MCU cores, structured as a master–slave microcontroller system. The three cores are the communication management engines, and uses a MQTT Client and cloud service layer for bridging transmission. The device management engine uses a blue tooth device to bridge the transmission with the sensing layer. The database management engine is responsible for the management of data sorting to allow database management to be equipped with efficient data searching ability. As a result, the required information communication and data management and analysis can be transferred from the cloud to the gateway end. In this way, the problem of immediacy and privacy of communication using the device can be solved. The experimental results have also shown that our three-MCU cores system has obvious advantages in the transmission efficiency and stability compared with the single core gate.
