An intelligent control system for traction bed is developed according to the traditional massage method and the needs of patients and doctors. This traction bed imitating artificial traction by using both a hydraulic system and a linear push rod motor can help the patients in bed to complete the intelligent traction, e.g. before and after stretching, left and right swing angle, axial rotation and Longitudinal rotation. In addition, this intelligent traction bed provides different traction modes for patients in bed with rapid traction and slow traction. The STM32 series chips are chosen and the intelligent traction bed combines with motor drive module and hydraulic drive module, as are used in the intelligent control system of the traction bed. The different width duty cycle output from the control system is to realize the control of hydraulic valve and a linear push rod motor. The traction bed's movement status is detected or corrected by angular speed sensors and pressure sensors, and the performance of the system will become better. An upper-computer software designed based on the platform of labView can control the underlying processor through the choice of the parameters the intelligent traction bed achieve the effect of human-computer interaction.

Abstract
An intelligent control system for traction bed is developed according to the traditional massage method and the needs of patients and doctors. This traction bed imitating artificial traction by using both a hydraulic system and a linear push rod motor can help the patients in bed to complete the intelligent traction, e.g. before and after stretching, left and right swing angle, axial rotation and Longitudinal rotation. In addition, this intelligent traction bed provides different traction modes for patients in bed with rapid traction and slow traction. The STM32 series chips are chosen and the intelligent traction bed combines with motor drive module and hydraulic drive module, as are used in the intelligent control system of the traction bed. The different width duty cycle output from the control system is to realize the control of hydraulic valve and a linear push rod motor. The traction bed's movement status is detected or corrected by angular speed sensors and pressure sensors, and the performance of the system will become better. An upper-computer software designed based on the platform of labView can control the underlying processor through the choice of the parameters the intelligent traction bed achieve the effect of human-computer interaction.
