Technology - Network Sensors - Guidance [Weikewei]

Network sensorsIt refers to the implementation of network protocols by sensors at the field level, enabling on-site measurement and control data to enter the network for transmission nearby, and to be published and shared in real-time within the network coverage area. Simply put, a network sensor is a sensor that can be connected to a network or connected to a microprocessor, computer, or instrument system through a network.

At present,Network sensors58彩票The application mainly targets two major directions.

58彩票(1) Distributed measurement and control

58彩票Arrange network sensors at the measurement and control site, at the lowest level of the control network. The information collected is transmitted to distributed intelligent nodes in the control network for processing, and then the sensor data is disseminated to the network. Other nodes in the network use information to make appropriate decisions, such as operating actuators and executing algorithms.

(2)Embedded systemnetwork

Although existing embedded systems have been widely used, most of them are still in the stage of standalone application, independent of the Internet. If embedded systems can be connected to the Internet, information can be easily and inexpensively transmitted to any desired location. The main advantages of embedded networks are: no need for dedicated communication lines, fast speed; The protocol is public and applicable to any web browser; The forms of information reflection are diverse, etc.
