Abstract:

In view of low automation degree of the silt grab hopper,this paper designs an automatic control system for the Silt grab hopper by using the STM32 Micro-processor as the main controller.Conditioning,acquisition and processing of external signals as well as data transmission are achieved by the rich peripheral hardware of the system.Real-time control of the silt grab hopper and on-line monitoring for its operation condition will be possible with HMI which is connected to the controller through RS485.To enhance the practicability of the system,the remote-control is introduced,which overcomes the disadvantage that the silt grab hopper cannot be operated by a single person.The practical application shows that the work efficiency of the silt grab hopper is greatly improved by the control system with the advantages of good human-computer interaction,high automation,simple operation and good maintainability.
