The application scenarios and solutions of GEFFEN smart campus management platform are composed of four parts: perception layer, transmission layer, application layer and platform layer, the underlying equipment is connected to intelligent terminals, sensors, etc. for statistical management and data collection, and the collected data is transmitted back through channels such as network collector gateways, and the returned data is managed and displayed by the platform in a unified manner.
● Perceptual layer
The perceptual layer is the skin and five senses of the entire system, and its main function is to recognize objects and collect information. Perception is composed of various hardware, including but not limited to intelligent terminals, network central controls, control panels, voice intercoms, lighting controllers, fan controllers, curtain controllers, air conditioning controllers, curtain controllers, intelligent circuit breakers, and sensors.
● Transport layer
The function of the network layer is "transmission", that is, information transmission through the communication network. The network layer is a link connecting the perception layer and the application layer, which is composed of various private networks, the Internet, wired and wireless communication networks, etc., which is equivalent to the human nerve center system, which is responsible for transmitting the information obtained by the perception layer to the application layer safely and reliably, and then processing information according to different application requirements. In the Geffen system, the transport layer is mainly TCP IP, Zigbee, RS-232, RS-485 and other networks.
● Application layer
The application layer is a unified encapsulation of various common capabilities, and users can directly use various applications. The application layer can calculate, process, and mine knowledge on the data collected by the perception layer, so as to achieve real-time control, accurate management, and scientific decision-making of the physical world. The specific applications are: management and control of various devices, audio and video broadcasting, intelligent operation and maintenance, data statistics, etc.
● Platform layer
The platform layer is a layer that takes software as the core and provides the development, operation, and management environment for the application layer, that is, middleware. The platform layer needs to solve the problem of how to provide a highly available, scalable, and easy-to-manage cloud middleware platform based on the resource management capabilities of the infrastructure layer.
