Multi-functional Intelligent Traction Bed System Design

Medicine for lumbar disc herniation,lumbar spine disease, which generally take the physical traction of conservative treatment. On the system's main functions and composition of the system software and hardware design. This design completes an intelligent physical therapy system to realize treatment in the neck, the keel, the lumbar vertebra hauling based on the multi-monolithic integrated circuits. This design selects the closed-loop control method, receives the keyboard entry and mechanics sensor inputs under controls of the monolithic integrated circuit, actuates electrical machinery impetus hauling organization realization hauling, simultaneously outputs demonstration of the input of the parameter and the running statu. The traction bed is two-step system for the treatment of bed platform, using ARM embedded processors, such as combining computer on the bed and the freedom of movement to achieve distributed control, implemented by the motor force quickly, and slow traction in bed The arbitrary point of the fast slow rotation, and focus on the use of Delphi6.0 complete PC software application development, is a good solution.The overall system divides into three major parts: the power unit, the hauling function part and the additional function part. The hauling function part composes of the signal gathering and processing module,the data acquisition examination module, the actuation modulethe keyboard entry module, the keyboard entry module, the nixietube demonstration module and the bed body 6 parts . The additional function part composes of the keyboard entry module, AT89C52 monolithic integrated circuit control module, the actuation module and the bed body . The power unit provides the power source for other two parts.The hauling function and the additional function complete separately by the controls of the monolithic integrated circuit.The software proportion is designed by using Distributed Control System Model under DICom protocol. We write this programe in Object Pascal with powerful DELPHI6.0 Windows application development tool so as to make the control of the bed body more flexible, reliable and efficient, and make the interface having friendly, simple, and easy to operate .Some new technologies are adopted in the development process ,and the most important is the Controls and Components.Especially in the serial communication,the use of Controls and Components has greatly enhanced the reliability of serial communication and the system.
