Abstract:Aiming at the problems existing in chemical engineering storage enterprises,e.g.,various categories of equipment,information isolation among each production unit,and the production data are unable to be properly measured in real time,thus the real-time of data acquisition system is designed and developed.By adopting different data communication specification,the production data are obtained from various heterogeneous system,and transported and stored through network protocol,the real-time and accurate measurement of the tank yard is implemented.Since the system has been putting into operation,the operational effect is good,and the problems existing in data acquisition of enterprises is efficiently solved;the system is significant to improve the level of information to enterprises.
Keywords:Data acquisition Data communication Real-time database Modbus Programmable logic controller(PLC)
