According to the classroom content, the state machine System state diagram can be described as follows:

The state machine system is designed according to the state diagram, the C language code is as follows:

1#include <iostream.h>2 using namespacestd;3 4 BOOL inch=false;//Vehicle Entry Brake sensor value5 BOOL  out=false;//Vehicle Exit brake sensor value6 BOOLpos =false;//Landing lever position sensor, false for drop, true for lift7 intENG =0;//motor control signal, 0 for stop, 1 for positive turn lift, 2 for inverted drop8 BOOLLig =false;//traffic light control signal, false for red light, true for green9 intn =0;//represents the current state of the systemTen  One voidStatus_1 () { AENG =0; -Lig =false; -cout <<"The landing lever has fallen.
