Embodiment Construction

[0031] The present invention will be described in detail below with reference to the drawings and embodiments.

[0032] The invention is used in the automatic docking mode of the bed and chair of the intelligent wheelchair bed system, which can realize a one-key berth, reduces the difficulty of operation for the user, and is convenient for the user. The present invention first installs an artificial road sign directly under the head of the auxiliary bed, and installs a camera under the rear of the smart wheelchair. When the smart wheelchair enters the berth area, the user will issue a docking command for the bed and chair through human-computer interaction. The intelligent wheelchair searches for artificial road signs in the camera's field of view by rotating autonomously in situ. After searching for the artificial road signs, the visual perception system calculates the image coordinates of the artificial road signs and transmits the artificial road signs information to the embed...

Abstract

The invention discloses an automatic bed and wheelchair butt joint method for an intelligent wheelchair and bed system. The automatic bed and wheelchair butt joint method for the intelligent wheelchair and bed system is used for controlling automatic butt joint between an intelligent wheelchair and an auxiliary bed body. The automatic bed and wheelchair butt joint method comprises the steps that a manual guidepost unit is fixed on the auxiliary bed body, and a visual perception system unit is installed behind the intelligent wheelchair; information of a manual guidepost is acquired through the visual perception system unit and transmitted to an embedded upper computer; intelligent wheelchair positioning and motion planning based on the manual guidepost are finished by the embedded upper computer so as to achieve automatic butt joint between the intelligent wheelchair and the auxiliary bed body. According to the automatic bed and wheelchair butt joint method for the intelligent wheelchair and bed system, automatic butt joint between the intelligent wheelchair and the auxiliary bed body is accomplished through automatic identification of the manual guidepost and automatic positioning and motion planning of the intelligent wheelchair, high butt joint accuracy is achieved, use difficulty of a bed and wheelchair integration system is reduced, and a user can conveniently use the bed and wheelchair integration system.

Description

Technical field [0001] The invention relates to the field of visual servoing and motion control, in particular to a bed and chair automatic docking method of an intelligent wheelchair bed control system. Background technique [0002] As the problem of aging society becomes more and more serious, a large number of persons with disabilities and long-term bedridden patients exist and continue to grow, making medical and nursing work face unprecedented pressure. The problem of helping the elderly and the disabled is increasingly becoming a major social problem. The intelligent wheelchair bed system based on the integrated design of bed and chair can provide the elderly and the disabled with a stronger ability to live independently, reduce the work intensity of the nursing staff, and improve the quality of life of the elderly and the disabled, and ensure the sustainable and stable development of the society It has important practical significance. [0003] A key problem in the intellig...
