Design and Implementation of Can Bus for Distributed Injection Molding Machine Based on Arm Controller

In this paper, the distributed intelligent control of plastic injection molding machine based on ARM controller through CAN field bus technology is proposed. The basic components of hardware and Software design are also discussed. The intelligent control system enables the procedure self-learning, fault diagnosing and process parameters such as temperature, injection pressure, flow, limit position etc., in the molding process. The ARM controller as a slave computer for this control system not only provides on-site monitoring but also can provide distributed remote control services for the host computer. The closed-loop control system, composed of the ARM controller and sensors, realizes the prompt adjustment of the processing parameters in the plastic injection molding machine
