The Design of Intelligent Sensor Interface Circuit based on 1451.2

At present, there are many complex and diverse bus interface standards in the field of sensor measurement and control, which leads that different sensors unable to be compatible with different field networks, thus increasing the difficulty of data acquisition and processing. In order to improve the compatibility and the intelligent level of sensors, in this work, a novel intelligent sensor interface model defined by IEEE1451.2 standard is proposed. Finally, the self-recognition, plug and play (PNP) functions are verified on FPGA platform.
