Research of Networked Intelligent Sensor Based on IEEE1451.2

On the basis of the interface standard IEEE1451.2 of network sensor, the paper put forward a design idea of networked intelligent sensor based on CAN Bus combining with development requirements of coal industry automation and technical features of CAN Bus. For network sensor nodes,the paper put forward a design method of online programming, and introduced hardware structure,digital communication interface of network sensors as well as TEDS design thought and communications data format in details.
