How to translate SAMA diagrams

http://bbs.hcbbs.com/viewthread.php?tid=422137 The Sama diagram is a standard established by organizations such as the American Manufacturing Association; it uses various symbols such as plus, minus, multiply, divide, derivative, integral, OR gate, AND gate, switch, maximum value, minimum value, upper limit, lower limit, etc., to indicate what kind of calculations the control system needs to perform, what kind of control it is subject to, and what constraints it faces. This makes it easy for relevant engineering and technical personnel to understand what processing the control system is carrying out, and it also allows them to determine whether it is reasonable, and what modifications can be made to achieve better results. In short, the Sama diagram is a recognized symbol or engineering language used by engineers and technical personnel for technical communication.
