Abstract: The present disclosure discloses a sensing function control node for an Internet of Things (IoT), and relates to technical field of electrical communication. The node includes an accessing module for sensors and actuators, a data format analyzing and integrating module and a transmission accessing and connecting module. Software-defined optical access technologies are utilized to control original sensing data in the IoT to access the accessing module for the sensors and the actuators. Status information of modules in the node is sensed in real time through a software-defined unified control plane, to adjust upload rates of modules and control the connections between sensing function control node and EAN. The original sensing data in IoT are transmitted to the transmission accessing and connecting module after being pre-processed. The pre-processed data are transmitted to EAN through upload channels between the sensing function control node and EAN established.
