Abstract

The invention relates to a voice control wheel chair with movement modes being adjusted according to physical condition, mental state and environmental condition, which belongs to the field of mechanical-electrical integration, and solves the problems that a common wheel chair cannot meet the demands of patients, and an intelligent wheel chair is too expensive to be served for common consumers. A neck pulse transducer is arranged under a bulge of a pillow part on the back of the wheel chair and is used for detecting a pulse signal; a respiration signal detecting circuit is used for detecting a respiration signal; a measuring distance transducer is used for detecting a relative distance signal; an ear-style hemopiezometer is worn on an ear of a patient to detect a blood pressure signal; a voice command control panel and a microphone are arranged for acquiring a sound voice; all the signals are analyzed by a control and analysis processer; the output end of the control and analysis processer is connected with the input end of an execution and alarm module; the execution and alarm module comprises an execution mechanism and an alarm module; and the execution mechanism is used for controlling a driving motor so as to drive a rear driving wheel and a front driven wheel to rotate according to commands.
