With the development of computer technology, network technology, and communication technology, networked measurement and control systems have become a new trend. Requirements for networked measurement and control technologysensorIt also has networked functions, hence the emergence of network sensors. Network sensors refer to sensors that implement network protocols on site, enabling on-site measurement and control data to be uploaded to the network nearby and published and shared in real-time within the network's reach.

Network sensorsDeveloping from single function single detection to multifunctional and multi-point detection; Developing from passive detection to active information processing; Developing from on-site measurement to remote real-time online measurement and control. Network sensors enable sensors to be connected to the network nearby, eliminating the need for point-to-point connections between sensors and measurement and control equipment. This greatly simplifies the connection lines, saves investment, is easy to maintain, and makes the system easier to expand.Network sensorsIt is generally composed of a signal acquisition unit, a data processing unit, and a network interface unit. These three units can be synthesized using different chips or have a monolithic structure.

网络传感器The core is to enable the sensor itself to implement network communication protocols. With the rapid development of electronics and information technology, sensor networking can be achieved through software or hardware methods. The software approach refers to embedding network protocols into the ROM of the sensor system; The hardware approach refers to using network chips with network protocols directly as network interfaces. It should be pointed out that due to the limited software and hardware resources of on-site network sensors, it is necessary to传感器It is obviously impossible and unnecessary to become a fully functional network node like a PC. Determine the specific functions of the sensor based on its usage requirements, such as whether the data to be collected or transmitted on site needs to be low-speed or high-speed, and whether a field level web server needs to send and receive data via email (SMTP protocol) or file transfer (FTP protocol).
