Cloud connection: Really solve the bottleneck of the Internet of Things connection layer

When it comes to the Internet of Things, its own technology has three layers of research from a research perspective, collectively known as DCM. The first is equipment. First, there must be an electronic tag chip. Secondly, there are accepted terminal devices, including mobile phones, telephones, televisions, mobile devices, and so on. The second is the connection, the data transmission channel. Now there is 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 (Cloud Connection) refers to the network in the safest and fastest way to achieve interconnection to demand, and scalable way to apply safe, reliable, and fast delivery to those who need. 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, it is possible to securely and quickly obtain the required resources from anywhere through the nodes.

After the cloud connection is implemented, 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 station”. 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 super node technology, users get more security and speed for the required applications.

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 The 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!

Speakers are one of the most common output devices used with computer systems. Some speakers are designed to work specifically with computers, while others can be hooked up to any type of sound system. Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener.

Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver. This input may be either in analog or digital form. Analog speakers simply amplify the analog electromagnetic waves into sound waves. Since sound waves are produced in analog form, digital speakers must first convert the digital input to an analog signal, then generate the sound waves.

The sound produced by speakers is defined by frequency and amplitude. The frequency determines how high or low the pitch of the sound is. For example, a soprano singer's voice produces high frequency sound waves, while a bass guitar or kick drum generates sounds in the low frequency range. A Speaker System's ability to accurately reproduce sound frequencies is a good indicator of how clear the audio will be. Many speakers include multiple Speaker cones for different frequency ranges, which helps produce more accurate sounds for each range. Two-way speakers typically have a tweeter and a mid-range speaker, while three-way speakers have a tweeter, mid-range speaker, and subwoofer.
