The Design of the Control System in the Power Dumbwaiter Based on CAN Bus and DSP

In view of the demand of distribution, real-time property and modularization, the CAN-bus and DSP is used in a power dumbwaiter control system to improve the system performance in real-time response and anti-interference. The main controller could communicate with the cabinet controller by point to point or global broadcasting. The master station could monitor the operation state of slave station in real time. The ac-tual result showed that this kind of designing manner is enable the system to implement its distributed control and raised the reliability of the system.
