When it comes to the Internet of Things, its own technology has three layers of research from the perspective of research, collectively known as DCM. The first is the equipment, which must first have an electronic tag chip, followed by an accepted terminal device, including a mobile phone, a telephone, a television, a mobile device, and the like. The second is the connection, the data transmission channel, which now has a wireless, wired connection, mainly through the Internet. Third, it is the management that needs to be connected after the object is interconnected, that is, the management of the Internet of Things application. In the three-layer technology of equipment, connection and management, the connection layer is the most closely related part of the Internet of Things and the Internet. At present, due to industrial barriers between different industries, there are information islands in different fields, which block the interconnection of information, making the “universal interconnection†required by the Internet of Things difficult to achieve. The cloud connection platform is the key technology to break through the bottleneck of the Internet of Things connection layer. Cloud ConnecTIon refers to interconnecting networks in the safest and fastest way to deliver applications securely, reliably, and quickly to those who need them in an on-demand, scalable manner. Cloud connectivity is a comprehensive representation of network connectivity in the era of cloud computing. It combines multiple modes and technologies such as SaaS, application delivery, and P2P. Each user is equivalent to a node, and a large number of client-side "super-node pool" applications are implemented. By establishing a connection channel, you can securely and quickly obtain the required resources from anywhere through any node. After the cloud connection is realized, the connection speed is no longer dependent on the local bandwidth resources, but on the huge network service. The more users, the more stable and fast the application is. The entire Internet is transformed into a huge “data transfer stationâ€. The more participants, the better the connection performance of each participant. There are two main characteristics of cloud connection: First, the required resources can be obtained anytime and anywhere: as long as the connection channel is established, the user can obtain resources on demand in any device and in any network environment through a unique passport; second, connection Performance: With SuperNode technology, users get the security and speed of the required applications more secure. Cloud connection schematic As can be seen from the above figure, the bus facilities, traffic command system, weather forecast system, road condition monitoring equipment, and mobile terminal are all cloud nodes. The application of cloud connection in the Internet of Things is essentially integrating the sensing layer, the connection layer and the application layer. The platform will distribute cloud connection nodes in a converged network formed by various communication networks and the Internet, thereby realizing various information between Interaction and sharing, breaking through the connection layer technology bottleneck of the development of the Internet of Things. Although the Internet of Things is a new thing, as early as the 1990s, the domestic sensor network has already proposed, and began to study applications, and the sensor network is what we now call the Internet of Things, the sensor network has experienced ten In the course of several years of development, both the technology and the environment have already met the conditions, and the Internet of Things has begun to be applied first in some enterprises. The realization process of the Internet of Things: labeling, sensing, transmission, management, and the transmission part is the concentrated expression of the value of cloud connection!
Android is an open source mobile operating system based on Linux platform released by Google at the end of 2007, and then improved for use in netbooks and MIDs. The platform consists of operating system, user interface and application software, and is claimed to be the first truly open and complete mobile software for mobile terminals.
To put it simply, the Android system is actually a very open system. It can not only realize the functions of the most commonly used notebook computers, but also realize various directional operations like mobile phones. Moreover, it is specially designed for mobile phones. The operating system developed for equipment has advantages in system resource consumption and human-computer interaction design. It is an operating system that combines traditional and advanced advantages.
