Application of functional analysis and supervision of a weighing system of a grain silo

After a presentation of the part of the automation and the supervision in the upgrading of the process systems, we present the issues involved in the application of a Functional Analysis (FA) technique on a supervisory system of a weighing system of cereals. Our contribution consists on applying a FA technique SADT (Structured Analysis Design Technique). This technique allows a functional description of the weighing system of cereals. The paper briefly discusses the functionality of the weighing system and some advantages of the application of the FA for the design of a supervisory system. Then the basic principles of the application of the supervision of the weighing system are presented. Finally, the different results obtained from the application of supervision are discussed.
