| Abstract: | Considering that the limited function of current electric care bed(ECB)for the disabled and the elderly is hard to be extended,the design of ECB control system based on CAN bus is presented by using the single chip AT90CAN128 to improve the extensibility of the control system.The operation mechanism of the control node in ECB is introduced.The hardware block diagrams are given,and the problems which should be paid attention to are explained.The software flow charts are provided,and the certainly defined CAN bus protocol is introduced.The experiment conclusions are given,and the key problems during the software development are discussed in details. |
