The specific embodiment
The present invention includes the other equipment of switchgear house equipment and machine; switchgear house equipment has low-voltage distribution cabinet; isolating switch, breaker, contactor and electrothermal relay are installed in the low-voltage distribution cabinet; the other equipment of machine comprises device signal lamp, start button, stop button, change-over switch, limit switch and conveyor trip switch, realize the sintering machine motor M startup, stop and various protections.The present invention also comprises master-control room equipment, frequency converter cabinet, PLC cabinet and level-sensing device.Master-control room equipment comprises computer, switch and Ethernet card.The frequency converter cabinet has breaker and frequency converter B P.The PLC cabinet has breaker, ethernet module, input module and output module.Described computer is connected with the ethernet module of PLC by Ethernet card, the thickness of sintering machine material set-point SP that real active computer is set inputs to the input module of PLC, and PLC sends thickness of sintering machine material information to computer and shows, as shown in Figure 1.The output module of PLC is connected with described frequency converter B P by the Profibus-DP net, and frequency converter B P is connected in the main circuit of sintering machine motor M, realizes the speed control to the sintering machine motor M.Described level-sensing device RPM is installed on the sintering machine, monitors the material thickness of sintering machine in real time, and level-sensing device RPM is connected on 12,13 pin of PLC, is connected with the input module of described PLC, forms negative-feedback.
The sintering machine frequency converter is controlled automatically: change-over switch pushes automated location, and PLC sends startup command, and auxiliary reclay K1 gets electric, and frequency converter terminal 5,9 is connected, and frequency converter begins to start.PLC passes to frequency converter by the DP net with frequency setting value SP, and frequency converter moves according to velocity amplitude.
Sintered material thickness is controlled automatically: the operator imports the set-point SP of thickness of sintering machine material on computer picture, set-point is sent to PLC by Ethernet from computer.Level-sensing device is measured material thickness on the sintering pallet, and measured value PV enters PLC through the PLC input module.The flow of sintering machine material is certain because disk feeder is given, and under the certain situation of sintering pallet width, thickness of sintering machine material and sintering machine speed are inversely proportional to, and promptly sintering machine speed is fast more, and then material thickness is thin more; Sintering machine speed is slow more, and then material thickness is thick more.PLC then carries out PID calculating according to the measured value PV of material thickness and the deviation of set-point SP, provides the sintering machine velocity amplitude.The sintering machine velocity amplitude is sent to frequency converter B P by the Profibus-DP net by PLC, and the Profibus-DP net is passed the ruuning situation of sintering machine back PLC simultaneously, shows by the computer monitoring picture again.Frequency converter B P controls the sintering machine motor M speed of service to the set-point of the velocity amplitude of receiving as frequency converter B P, thereby reaches the purpose of control material thickness.When the material thickness measured value than set-point hour, the sintering machine velocity amplitude that PLC provides increases; Otherwise when the material thickness measured value was bigger than set-point, the sintering machine velocity amplitude that PLC provides reduced, and realized the stable of material thickness.
