Problems solved by technology
Among the methods to prevent motion sickness, most people will choose physiological methods such as taking motion sickness medicine or smell stimulation, but swallowing medicine to solve it may not be the best choice for most people, because their own pharmacological effects on Some people are not suitable, and odor stimulation does not have universal applicability. Relatively, the method of preventing or alleviating motion sickness through the control of external mechanical motion is more universal and safe. In the patent, there is no device or method to prevent or alleviate the symptoms of motion sickness from the level of controlling mechanical movement

The invention discloses a seat embedded type control system for relieving kinesia. The seat embedded type control system comprises a PC upper computer, a compactRIO embedded controller, a C-series module, sensors and an actuator. The PC upper computer is connected with the compactRIO embedded controller, and the compactRIO embedded controller is connected with the C-series module; a shock absorbervariable-damping proportional valve used for adjusting the damping of a car seat suspension is mounted in a shock absorber, and a spring variable-stiffness proportional valve used for adjusting the stiffness of the car seat suspension is mounted in a spring; and the sensors comprise the acceleration sensor and the resistance strain type sensor, the acceleration sensor is worn on the human head for acquisition of vibration signals, and the resistance strain type sensor is mounted on the surface of a seat cushion for measurement of the static load of a human body. The invention provides a safeand high-comfort seat embedded type control system for relieving kinesia and a method.
Description
technical field [0001] The invention relates to the technical field of seat control, in particular to a seat embedded control system and method for alleviating motion sickness. Background technique [0002] In the process of traveling by traffic, some people will suffer from motion sickness (motion sickness) and experience symptoms of nausea and vomiting. External mechanical movements or objects in the field of vision may cause discomfort to some people, such as repeated bumps of the vehicle , object movement in the eye field of view, etc., and severe motion sickness (motion sickness) is caused. Among the methods to prevent motion sickness, most people will choose physiological methods such as taking motion sickness medicine or smell stimulation, but swallowing medicine to solve it may not be the best choice for most people, because their own pharmacological effects on Some people are not suitable, and odor stimulation does not have universal applicability. Relatively, the ...
