Aiming at the lower automation, accuracy and efficiency of the domestic band sawing machine, this paper studies the real-time detection technology based on the sawing load, develops the digital control system of the constant power sawing with the micro-feed performance to improve the load imbalance of the band saw blades in the sawing process. The real-time detection technology based on the micro-deviation of the band saws trajectory is studied. The digitized deviation-correction control system of the band saws trajectory is developed with the fine-tuning performance of the saw stiffness to correct automatically the band saws trajectory. The weight-detection technology based on the scan reconstruction of the surface profile size is researched. The digital control system of the fixed weight sawing is developed to meet that the weight error of the sawed workpiece is fewer than 3%. That can improve the accuracy and efficiency of the band sawing machine and provide the foundation for the realization of the digital control of the band sawing machine.

Ship loader is one of the most key equipments for bulk material handing in bulk port. This paper regards the ship loader as the study object, introduces an auto detection technology of cabin position and material distribution, and advances a new control measure for automation loading. The field-bus technology of Profibus, AC800M series PLC, inverter, encoder was adopted to build automatic control system. In the mean time, the control code and the ship loader Management System, which is written in Control Builder for AC800M and Visual Basic independently, are used to actual ship loading process without people.
