Embodiment Construction

[0041] Embodiments of the automatically controlled wheelchair of the present invention will be described in detail below with reference to the accompanying drawings.

[0042]The most important consideration when choosing a wheelchair is its size. The main parts where wheelchair users bear weight are around the ischial tuberosity of the buttocks, around the femur, around the fossa and around the scapula. The size of the wheelchair, especially the width of the seat, the height of the backrest and the height of the backrest, and the distance from the pedal to the seat cushion will affect the blood circulation of the occupant's relevant parts of the force, and cause skin abrasions and even pressure sores. In addition, the safety of the patient, the ability to operate, the weight of the wheelchair, the location of use, and the appearance of the wheelchair must also be considered.

[0043] The current level of wheelchair intelligence is not high, and there is still a lack of effect...

Abstract

The present invention relates to an automatic control wheelchair. The wheelchair is equipped with such a control mode switching system. The system includes: an acceleration measuring instrument, which is arranged on the wheelchair, and is used to detect the acceleration value of the wheelchair, and when the acceleration value of the wheelchair When the acceleration threshold is greater than the preset acceleration threshold, an acceleration warning signal is sent; the deflection angle detection device is set on the wheelchair to detect the deflection angle value of the wheelchair, and when the deflection angle value of the wheelchair is greater than the preset deflection angle threshold value, a deflection angle detection device is sent. Angle early warning signal; ARM11 processing equipment, used to send a fall alarm signal when receiving the acceleration early warning signal and receiving the deflection angle early warning signal; image acquisition equipment, used to collect high-definition image data for wheelchair users, to obtain a high-definition target image; wherein, the ARM11 processing device realizes switching of the control mode of the wheelchair based on the output of the image acquisition device.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an automatic control wheelchair. Background technique [0002] When choosing a wheelchair, you should pay attention to the following issues: [0003] (1) Seat width: measure the distance between the buttocks or the two thighs when sitting down, add 5cm, that is, there is a gap of 2.5cm on each side after sitting down. If the seat is too narrow, it will be difficult to get on and off the wheelchair, and the buttocks and thighs will be oppressed; if the seat is too wide, it will be difficult to sit firmly, it will be inconvenient to operate the wheelchair, the limbs will tire easily, and it will be difficult to enter and exit the gate. [0004] (2) Seat length: measure the horizontal distance from the buttocks to the gastrocnemius of the calf when sitting down, and subtract 6.5cm from the measurement result. If the seat is too short, the weight will mainly fall on the ischia, whi...
