| Summary: | 碩士 === 明志科技大學 === 電子工程系碩士班 === 106 === Markets & Markets, a renowned international market research company, in the year of 2016 published a study. In the study, it observed that the market of Internet of Things (IoT) is expecting to grow into US$667.14 billion business by the year of 2021, having a Compound Annual Growth Rate (CAGR) of 33.3% from years 2016 to 2021. It indicates that the IoT has immense potential. The IoT can have a wide range of applications implemented in today’s industrial technologies as well as daily lives. Based upon IoT fundamentals and concepts, an intelligent Physical Access Control System (PACS) is designed, deployed and developed in the thesis. According to the traditional PACS experience, it requires tremendous efforts to collect, aggregate and analyze door readers' statuses and events. Therefore, the study has utilized the networking control and management approaches integrated with the IoT fundamentals applying onto the architectures of PACS. The enhanced System can more effectively and efficiently collect and analyze door readers' statuses and events than those of the traditional ones.
In this thesis, the PACS implementation can be categorized into two aspects. First, the PACS has been designed and implemented as two layers of structures, the “manager” and the “readers” layers, respectively. In addition, a set of instructions is designed as the access control rules, which is implemented in a distributed, time series database, Cassandra, and enclosed in the System. It can provide PACS data consistency and availability. Furthermore, the System can conduct resource accessibilities via the access policy list.
Secondly, through fault approaches over networking management, events handling in PACS is explored and implemented based on IoT event management mechanism. Therefore, the door readers' behaviors variables are defined by the Structure of Management Information (SMI) and the Management Information Base (MIB). The variables are collected via Simple Network Management Protocol (SNMP) which can define the rules of events triggering and further record the events.
Finally, the PACS results are exhibited with high operability. In the System, it provides user friendly interfaces in order to achieve convenient operations for door readers. The PACS also includes intuitive accessibilities for monitoring and management.
