Semafor7+123Triangles BT

This is my first work on it, and I coded the indicators a bit. .
SEMAFOR increased from 5 to 7.
I personally feel that 5 may not be enough. So the number of experimental ones increased to seven


Thanks to Mr. andrei-1 for his help. I have successfully solved the problem. Thank you very much
Grateful
