Oil tank area monitoring system is the basic component of petrochemical industry, part, along with the continuous development of petrochemical industry, the requirements of oilcan monitoring system more and more is also high. Traditional methods have can’t satisfy the measurement precision, tank farm for the high security requirements. Therefore design development of a typical and openness, high reliability of the jetty to promote the jetty monitoring system safety, high efficiency production is very meaningful.Based on the actual terminal monitor system renovation project, from the development of fieldbus technology study began, through a variety of comprehensive comparison of the control system, the choice 400H Siemens s7-300 PLC as lower level computer DCS control system, with the remote distributed I/O basis, realize the oilcan section level, temperature, pressure and other parameters of the monitoring; And use programming software Siemens Step7 v5.3 and configuration software WinCC complete software design, realization of the jetty real-time monitoring, remote control, security alarms, and print function.From the system of testing, each index all at the achieved the design requirements and function, oil tank area monitoring system for the control and management provides convenient.
