The present invention relates to automated remote controlling of moving machine through a unified operating platform. In particular, the present invention is directed to provide a centralized wireless connection enabled automated moving machine control system for instantaneous on-line diagnostics and monitoring of multiple moving Stacker cum Reclaimers (SCR) machines. The present system is particularly useful for remote controlling and monitoring of multiple Stacker cum Reclaimer (SCR) machines used for stacking as well as reclaiming of Iron ore and other materials in steel processing plant.
BACKGROUND ART.:
Stacker cum Reclaimers (SCRs) are widely used in steel processing industries for stacking as well as reclaiming of Iron ore and other materials. In the existing SCR control system, communication between Operator Cabin of the SCRs and PLC enabled Control Room is made through hard wired control cables. These control cables are prone to frequent damages, which result delay in stacking & reclaiming operation. Also, in these existing systems there was no communication facility available between SCRs and Central Control Room (CCR) & various Dispatchers of a steel processing plant. The limitation of the existing SCR control system are listed hereunder
• Breakage of signal cables between Operator Cabin & PLC Room of the SCRs results in stoppage of the machine hence delay in stacking & reclaiming
• Multi-core control cables give frequent maintenance problems
• Any breakdown in SCR m/c affects stacking, reclaiming, tippling & blend mix production affecting hot metal production & high demurrage
• Poor annunciation system in Operator Cabin of the SCR machine
• Absence of online diagnostics leads to delays in corrective action
• No centralised interfacing system for SCR machines
• Absence of any feedback system in CCR (Central Control Room) & lack of coordination between SCR & CCR
There has been thus a need in the art to developing an advanced and automated system for remotely controlling multiple moving machines as used in steel processing industries like SCR through a centralized operating platform, for effective controlling of stacking as well as reclaiming of Iron ore and other materials.
