Methods Frequency converter was adopted to control motor operating frequency so as to achieve energy saving, noise reduction and appropriate levitation force setting. Serial port control panel based on RS485 transmission protocol was used to carry out human computer interaction. Results Energy saving and noise reduction were achieved and levitation force could be adjusted according to the clinical treatment 1 1 plan. Conclusion Medical suspension bed based on frequency conversion control can significantly improve ZHANG Ming-xu , JIANG Man-fa , XU Hai-shu1 2 the effect of adjuvant therapy as well as realize energy­savin
