Motor Drive Module Design for Electric Care Bed
Peng Yang, Shujuan Zhu · International journal of intelligent engineering and systems · 2010
The electric care bed control system is divided into three modules, which are physiologic parameter detection module, human-computer interaction module and motor drive module (MDM).Those modules communicate with each other by controller area network (CAN) bus.Under the idea of modular design, a plug and play (PnP) multifunctional motor drive module (MDM) is developed.This MDM has a CAN interface which can make it possible to communicate with human-computer interaction module, and then control the position closed-loop and speed closedloop.The MDM based on CAN bus will be more efficient in communication and system expansion and make the electric care bed function perfectly.
