An automated crown block anti-collision system. The automated crown block anti-collision system comprises: a traveling track (1); a crown block (2) movably mounted on the traveling track; a photoelectric sensing device (4) provided below the track and used for forming a protection region below the traveling track and for outputting a feedback signal when a foreign body is detected to enter the protection region; and a control system (7) connected to the crown block and the photoelectric sensing device, the control system being used for controlling, when the feedback signal is received, the corresponding crown block that is working to stop moving.
