Hydraulic Control System

This paper introduces the hydraulic control system design for the change-wheel garage of Chongqing light rails through analysis of three-stage cylinder synchronization circuit for lifting bodies, and optimizing the design of the slewing mechanism with respect to the hydraulic servo control system of digital cylinder. The results improved the smoothness in the process of changing wheel lifting and the rotary accuracy of the rotary mechanism. Design on the PLC control system of the system is also included as part of this paper.

Plc Control System

This article describes the design of an articulation robot arm with seven joints. The control core of the robot arm is the module-based system built using the Mitsubishi Q series programming logical controller (PLC). The robot arm contains seven AC servomotors, seven driver devices, a vision system and a PLC control system. The PLC-based controller programs the motion trajectory of the gripper to catch or hold the objects and finish the assigned tasks. Kinect system (Asus Xtion Pro-Live, or called RGB-D sensor) acts as the vision system to recognize shape and color of each object. During the experiments, we found that the robot arm recognizes the shape and color of each object, and catches each object moving to the assigned box with the same color.

Transplanting of plug seedling is one of the most important operations during vegetable and flower production. Due to the higher labor intensity and lower efficiency for the operation, it is difficult to enlarge production scale for vegetables and flowers. Although transplanting of plug seedling is now common method, all operations are still manually conducted in China. To enlarge productivity for increasing food supply, it has become an urgent task to achieve automation of plug seedling transplanting for Chinese horticulture industry. This paper deals with the automatic transplanter for plug seedling, which is significant to promote development of production automation of seedling nursing and transplanting in China. Then, the simple, practical automatic transplanter for plug seedling, including manipulator, conveyor system for plug tray and flowerpots, overall structure and PLC control system was designed. Finally, Prototype was manufactured and performance tests were conducted. Results showed that the automatic transplanter had reliable transplanting performance.
