The Design of Modularized Oil Tank Measurement and Control Intelligent Unit

摘要

In this study, we design a modular intelligent measurement and control unit applied to the on-site oil storage tank to meet acquisition and processing of signals from typical liquid level meters, pressure transmitters, temperature sensors and others with various parameters, multiple protocols and hardware interfaces. We transmit metering parameters of each oil tank to the upper management database through the standard CAN bus. On the basis of the equipment, the distributed measurement and control network for storage tanks of the oil depot is built, which can be adapted to features of storage tanks in the oil depot (scattered and widely distributed) and overcome shortcomings of various instruments in the traditional metering system, such as mutual imcompatibility, different complex structures, great integration difficulty and so forth.
