In this thesis, the system can control the development of the electric hospital bed to complete the following tasks: design that can be used to control an electric hospital bed hospital ward carrying patients; the electrical wiring system of the bed, control systems and mechanical structure design calculation and three-dimensional simulation analysis to optimize the movement of the main structure, but also on the strength of the key elements of the finite element analysis; through the actual clinical trials to prove the safety of the product of this thesis, validity and applicability.
