In practical applications, network-based perception control intelligent front-ends are widely used in smart homes, industrial automation, environmental monitoring and other fields. For example, in smart homes, smart front-ends can sense various parameters of the home environment and automatically adjust the operating status of home appliances according to user needs; in the field of industrial automation, smart front-ends can realize real-time monitoring and remote control of production equipment. Improve production efficiency and quality; in the field of environmental monitoring, intelligent front-ends can monitor environmental parameters such as atmosphere and water quality in real time, providing data support for environmental protection.
With the continuous development of technologies such as the Internet of Things, cloud computing, and big data, the functions and performance of network-based perception control intelligent front-ends will be further improved, and their applications in various fields will become more extensive and in-depth.
