and step 3: the first distance sensor and the second distance sensor send detected distance signals to the control room processor through signal lines, and the control room processor controls the control room alarm to be opened and closed through the switch;

and 4, step 4: a first camera is arranged at the bottom of one end of a cross arm of the crane;

and 5: the first camera sends the shot video information to the control room processor, and the control room processor displays the video information on the control room display screen.

As a still further scheme of the invention: the method comprises the following steps:

step 1: installing a first distance sensor at a crane hook;

and 5: a second camera is arranged at the top of one end of the crane cross arm;

step 6: the first camera and the second camera send shot video information to the control room processor, and the control room processor displays the video information on the control room display screen.

The invention has the beneficial effects that:

through setting up first distance sensor, the second distance sensor, first camera and second camera, when the loop wheel machine used, through first distance sensor and second distance sensor respectively real-time supervision loop wheel machine lifting hook department and the distance between loop wheel machine xarm one end and the barrier, play the effect of early warning in advance, the aerial situation of loop wheel machine xarm one end top and bottom is shot in real time to first camera and second camera simultaneously, make things convenient for the staff to judge the adjustment, convenient operation realizes effectively avoiding bumping, it is safer to use.
