Design of oil tank monitoring system, first determine the system design objectives and functional requirements, feasibility analysis from technical and economic point of view, then the scheme selection and design, considering the structure of hardware circuit is reasonable, cost-effective, to explore the functional framework PC oil tank monitoring system, the data structure and other details, then the detailed design and debugging, finally completed the design task. In the early stages of design, the main consideration of the following factors:
(1) reliability. Oil tank monitoring system operation is safe and reliable, stable performance, can be long-term continuous fuel dispensing equipment working in harsh environment.
(2) general. In the design, should fully consider the application object in common, the oil tank monitoring system has strong versatility, can be popularized in oil depot.
(3) compatibility. Oil tank monitoring system should be able to carry on different types of sensors, can measure various parameters.
(4) economy. tank level gauge system cost, high performance price ratio.
(5) the operation and maintenance convenience. In the aspect of software requirements, friendly man-machine interface, easy to operate; the hardware requirements, convenient maintenance and repair. Parameters of tank area set and modify: setting tank number, label setting, communication parameters, tank partition management definition.
