摘要
基于HART协议的现场总线设备已被广泛应用于工业过程控制中。在石油生产过程中,将HART总线应用于石油井下温度压力的采集,能够改善传统采集设备和方法的不足,避免输油杆断裂、脱扣等事故的发生,并大大提高了实时数据采集的精度。
The Field bus device based on HART protocol has been widely used in industrial control.In the production of petroleum,the method which using the HART bus to transfer the temperature and pressure data collected from the oil well,can improve the traditional collecting method＇s shortage,prevent the failure of the data transfer caused of the rupture of the oil transfer pole,moreover,can enhance the collection accuracy.
