32040.基于物联网的数控监控系统的设计与实现
[计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2014-09-05]
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.
