First determine the system design goals and functional requirements

Design automatic tank gauge systems, first determine the system design goals and functional requirements, feasibility analysis on the technical and economic point of view, and then select fuel management systems the program and the overall design, consider the lower computer hardware circuit structure is reasonable, cost and other issues, explore the functional framework the host computer, the details of the data structures used, then the detailed design and debugging, the final completion of the design task. In the initial design, the main consideration of the following factors:
(1) reliability. Automatic tank gauge systems is safe and reliable, stable performance, long-term continuous tank level gauge systemoperation in harsh environments.
(2) versatility. At design time, you should take full account of their common application objects, the automatic tank gauge systems has a strong versatility, can promote the use of depot.
(3) compatibility. The fuel monitoring system should be able to carry different types of sensors linked to, a variety of parameters can be measured.
(4) economy. Reasonable economic cost of the automatic tank gauge systems, high cost performance.
(5) ease of operation and maintenance. On the software side, requiring friendly interface, easy to operate; hardware, easy maintenance and overhaul requirements. Tank area parameter settings and modify: the number of storage tanks, label set communication parameters, storage tanks partition management definitions.
