In this embodiment, each time a signal of the proximity switch for the deceleration position of the moving rack is received in each cycle of the moving rack operation, a shift process is performed for the data state of each slot until the current cycle of the moving rack operation is completed. The rotating shaft below the movable rack drives the rack to do periodic reciprocating motion, and each reciprocating motion of the movable rack enables the steel in each groove on the rack to move forwards by one groove; when the movable rack reciprocates each time, the movable rack makes a circular motion, starts to move from the lowest position to the highest position and then lowers from the highest position to the lowest position. And the two sides of the rotating shaft of the movable rack are respectively provided with a proximity switch, one is a deceleration position proximity switch signal for sensing that the movable rack moves from the lowest position to the highest position, and the other is a stop position proximity switch for sensing that the movable rack moves from the highest position to the lowest position. When the moving rack reciprocates for a plurality of times in each period of the moving rack action, the data state of each groove is shifted once each time the moving rack deceleration position approach switch signal is received, so that the data state of each groove is shifted for a plurality of times in each period of the moving rack action.
In this embodiment, the time T at which the rack deceleration position approach switch signal is received at each cycle of rack motion is determined; in each period of the action of the movable rack, when a rack deceleration position approach switch signal is not received in the time T, after a certain time T1 of the time T, the data state of each groove is subjected to shift processing, and the data state of the current groove is taken as the data state of the next groove; the state of the first groove of the rack is marked as a steel-free state. In this embodiment, time T1 may be set to 500ms, i.e., T +500ms is used as the time pattern substitute signal instead of the deceleration bit proximity switch signal.
In this embodiment, in the billet transport direction, when the data state of the last slot on the cooling bed rack is a steel state, the count value of the steel chain in the row is increased by 1.
In this embodiment, in step 2, in each period of the skirt plate action, a specific process of identifying whether the skirt plate has steel to be pulled down to the cooling bed when the skirt plate is currently in action is as follows:
firstly, determining whether a rolling area on a continuous rolling production line is subjected to simulation test; wherein the rolling area simulation test refers to a steel rolling simulation test in the rolling area;
detecting a steel signal of a rolling area on a continuous rolling production line under the condition that the rolling area on the continuous rolling production line is not subjected to a simulation test;
under the condition that a steel signal is detected in a rolling area on a continuous rolling production line, judging whether a heat detection signal before the first flying shear disappears or whether a shearing signal of the first flying shear is detected before the skirt board moves currently; if yes, the apron board is judged to have lower steel shifting to the cooling bed when in current action.
In the method of the embodiment, in each period of the apron board action, data state marks are made for the first grooves on the racks of the cooling bed by identifying whether steel is pushed down to the cooling bed or not; in each period of the action of the movable rack, all steel of the cooling bed rack can be accurately positioned and tracked through the displacement processing of the data state in each groove, so that whether steel exists in each groove on the rack can be accurately judged, the accuracy rate reaches 100%, the situation that post personnel mistakenly judge the cooling bed through video monitoring due to the video precision, the angle and the like is avoided, and great convenience is brought to the post personnel.
