Jamming monitoring and controlling system and method for weighing hopper

The invention discloses a jamming monitoring and controlling system and method for a weighing hopper. By collecting the discharging amount of the weighing hopper in the weighing interval time in realtime, the discharging state of the weighing hopper is judged; and if jamming occurs, a PLC is used for controlling a vibration motor to generate vibration, and as the vibration motor is fixedly connected with the weighing hopper, furnace materials in the weighing hopper are loosened and vibrated to be uniformly spread on a belt below a groove. The influence of jamming of the weighing hopper on thedischarging speed of the weighing hopper is eliminated, the continuity of a discharging system is improved, and the production efficiency is improved. Meanwhile, an alarm can be automatically sent out for warning to arouse attention of operators when jamming occurs, and the working efficiency is improved. 本申请公开了一种称量斗卡料监测与控制系统和方法，通过实时采集称量斗在所述称量间隔时间内的放料量，判断称量斗的放料状态，如果发生卡料，通过PLC控制器控制振动电机产生振动，振动电机与称量斗固定连接，称量斗内的炉料发生松动和振散，均匀的铺在
