Software and hardware complex of transporter operation control
If all the equipment operates in normal mode, the winding interval of the roll is approximately 1.5 minutes. Then the winder unloads the roll of the cart, which transfers it to the conveyor, and at this time another winder starts winding. Winded rolls are moved from the winder further down the technological circuit by the means of transporters. Thus, transporters are very important unit. Transporter long-lasting operation stop may force operators to stop the operation of the mill because of the impossibility of unloading wounded rolls from the winder.
Transporters of JSC “Zaporizhstal” are conveyor type, which consist of consistent sections. For various reasons during transporter operation may occur a situation when mechanical connection between the engine and the circuit is lost resulting in the stop of this transporter section, as a result the rolls which moved on this transporter stop. At the same time, the previous transporter sections of the circuit continue to work, and the rolls begin to accumulate and damage each other.
If given situation occurs, automatic shut down of transporter emergency sections and previous to them sections is needed. The old systems of motor protection did not allow to detect the transporter section stop and notify the operator about emergency situation.
