摘 要：Aiming at the shortcomings of the traditional CNC sensor network such as the difficult cable laying and long-distance communication signal attenuation,this paper designs the CNC monitoring system based on Internet of Things technology.The design reduces the power consumption of wireless sensor nodes and the packet loss rate of the sink node through hardware-software co-design.The Internet of Things protocol presented in this paper achieves the real-time communication between the CNC operating platform and the wireless sensor nodes.The experiment result shows that the CNC monitoring system based on Internet of Things technology can provide the temperature and vibration information for the CNC operating platform in time with the advantages of simple layout and reliable communication.
