文摘The Field bus device based on HART field communications protocol has been widely used in industrial control. In the pro-duction of petroleum, the method which using the HART bus to transfer the temperature and pressure data collected from the oilwell, can improve the traditional collecting method's shortage, prevent the failure of the data transfer caused of the rupture of the oiltransfer pole, moreover, can enhance the collection accuracy.
