Design And Implementation Of Intelligent Sensing Node

In recent years, with the development of the IoT industry, the sensing node can not meet the growing requirements, including data collection capabilities, low power consumption, flexibility and so on.In this dissertation, a set of perceived control system based on an agriculture related IoT application has been designed, which consists of clients, servers and sensory nodes. This system achieves the display of sensors data and the configuration of sensory nodes by web page, which minimizes the human intervention and increase the flexibility of the deployments. In addition, this dissertation designed a universal word to control the nodes and acquire some data from the nodes to the servers, which increase the software portability when the data exchange between the sensing nodes and servers.This paper focuses on the completion of the hardware design of intelligent sensing node based on the modular design concept. Intelligent sensing nodes using a low-power embedded processor platforms Cimsys FC3180 to realize analog-digital conversion and the interactive of sensors control and communication modules. In the sensor data access, the nodes provide serial port, such as standard voltage and current mode analog input and other types of general-purpose interface. In addition, the nodes can reduce the design and manufacturing cost by designing a common sensor interface and a communication module interface. The date exchange between the nodes and the servers program by Ethernet,2G/3G and so on.Ultimately realized the test from the display and control of the web to the server program and to the intelligent sensing nodes, and applied in "Smart Scarecrow" project in the Wuxi Research Institute of Fudan University. The sensing nodes achieve the intelligent monitoring of the comprehensive environment information on crop growth, and remote configuration of each sensor and other functions.
