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.

Description

technical field [0001] The invention relates to a voice-controlled wheelchair capable of adjusting motion patterns according to people's physical, psychological and environmental conditions, and belongs to the field of mechatronics. Background technique [0002] As one of the main means of transportation for the elderly and the disabled, wheelchairs are divided into ordinary wheelchairs and smart wheelchairs. [0003] Ordinary wheelchairs are divided into two categories: manual wheelchairs and electric wheelchairs. Manual wheelchairs account for most of the usage rate due to their price advantage, but they have single functions, monotonous shapes and colors, and require guardians, which easily form the dependence of patients on guardians. There is little development, and they cannot meet the deeper needs of patients at all. Complete satisfaction and unsatisfaction of spiritual needs are extremely detrimental to the mental and physical health of patients. Moreover, the rang...
