In the era of the Internet of Things, what are the outstanding points of intelligent building system

Characteristics of intelligent building system: (1) The overall architecture of the Internet of Things is fully presented, and the top layer realizes the overall management and control with cloud computing technology. (2) The perception layer will be composed of all kinds of network sensors, including all sensors in the building control system, industry cognitive cameras, infrared radiation sensors, various access control sensors, smart water and electricity meters, fire probes, etc., all of which will form the sensing network of the building "intelligent" large control system in the form of network structure.

3) The network layer will be composed of a transmission medium and an IP function controller, which is to use the integrated wiring system as the transmission medium, and transmit the sensing layer signal to the corresponding IP function controller through the communication protocol of the Internet of Things standard. (4) The application layer will be composed of centralized management and functional software for decentralized applications, which still conforms to the "principle of distributed control". The functional software determines the application scope and control function of the IP function controller, and can realize different functional control requirements at the same management level to achieve a large integrated control mode.

5) Large-capacity on-site storage devices at the building level, including a large number of historical data storage devices (now mainly building energy consumption collection servers, storage servers and analysis servers, etc.), ** storage devices (now mainly hard disk recorders, etc.) will be gradually replaced by network backup systems - "cloud storage" platform. (6) cloud computing as the top of the centralized management and control platform, to achieve the overall control function of the building group, the crane "distributed control" principle will be a single building of the "small distributed control" system extended to the building group of the "large distributed control" system, so that the overall sensing unit of the building complex (the sensor of the perception layer), the control unit (the application layer of the IP function controller and the function control software), the execution unit (the application layer of the IP function controller and the field execution equipment), The feedback unit (the feedback mechanism and sensor of the perception layer) forms a large control loop to realize the large-scale closed-loop control and management of the building complex.

3) The application layer includes application infrastructure, middleware, and various IoT applications. Application infrastructure Middleware provides general basic service facilities, capabilities and resource call interfaces for IoT applications such as information processing and computing, and realizes various applications of IoT in many fields on this basis.

Answer]: The network layer includes the convergence of communication and the Internet, such as the network sail key, the network management center, the information center and the intelligent processing center, etc., which transmit and process the information obtained by the perception layer. In short, the network layer design of the Internet of Things requires software designers to be familiar with the design structure of the sensor network, keep data not lost, and balance the design workload at both ends.

The key to the network layer design of the Internet of Things is to obtain signals from the end state to ensure that the signals are smoothly imported from the sensor side to the web setvice, which is the data fusion of mobile, telecom and Internet.

The three levels that make up the Internet of Things are:

IoT perception layer, IoT network layer, and IoT application layer. The data collection and perception of the perception layer are mainly used to collect physical events and data that occur in the physical world. The network layer realizes a wider range of interconnection functions, and can transmit the perceived information without barriers, high reliability and high security. Application layer: The application layer mainly includes the application support platform sub-layer and the application service sub-layer.

The Internet of Things (Internet of Things) refers to the real-time collection of any object or process that needs to be monitored, connected and interacted with through various information sensors, radio frequency identification technology, global positioning systems, infrared sensors, laser scanners and other devices and technologies, and collects various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, and location.

Through all kinds of possible network access, Gaoqing realizes the ubiquitous connection between things and things, things and people, and realizes the intelligent perception, identification and management of objects and processes. The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc., which allows all ordinary physical objects that can be independently addressed to form an interconnected network.

The Internet of Things (IoT, Internet of Things) is the "Internet of Everything", which is an extension and expansion of the network based on the Internet, which combines various information sensing devices with the network to form a huge network to realize the interconnection of people, machines and things at any time and place.
