Problems solved by technology

For some people with poor self-care ability, ordinary electric wheelchairs are not easy to operate, especially when encountering obstacles, they may not be able to respond in time
In addition, in many cases, even if you have responded in time, you cannot operate the wheelchair in time so that the wheelchair can avoid obstacles

Embodiment 1

[0027] The reference picture is Figure 1-5 . A cloud simulation intelligent obstacle avoidance system for wheelchairs, comprising: a cloud processor 1, an unmanned aerial vehicle 2, a wheelchair 3, the wheelchair 3 includes a processing device 4, a drive motor 5, a first camera 6, and the unmanned Machine 2 comprises CPU chip 7, photographing device 8, and described cloud processor 1 is synchronized with described processing device 4 and described CPU chip 7 data, and described first camera 6 is used for taking real-time image around wheelchair 3, and transmits to Described cloud processor 1, described photographing device 8 four sides are all provided with second camera 9, described photographing device 8 is used for shooting real-time street view, and described real-time street view is synchronized to described cloud processor 1, so The cloud processor 1 includes a three-dimensional real-scene simulation module 10 and a computing module 11, and the three-dimensional real-s...

Embodiment 2

[0038] The reference picture is Figure 6 . When the drive motor 5 drives the wheelchair 3 to change direction, the cloud processor 1 simulates the direction change circuit according to the three-dimensional real scene.

[0039] The cloud processor 1 judges whether there is a dangerous situation within the surrounding range of the wheelchair 3 according to the three-dimensional real scene image, and if so, sends an emergency avoidance instruction to the processing device 4, and the emergency avoidance instruction is the first priority instruction , the processing device 4 sends an emergency avoidance signal to the drive motor 5 according to the emergency avoidance command, and the drive motor 5 controls the wheelchair 3 to perform emergency avoidance according to the emergency avoidance signal.

[0040] Specifically, the cloud processor 1 simulates the reversing route of the wheelchair 3, and judges whether there is an obstacle on the route. A fine-tuning signal is sent to t...

Embodiment 3

[0043] The reference picture is Figure 2-3 . The UAV 2 is a shared UAV, and the UAV 2 has a positioning device, and the positioning device is used for positioning, and the CPU chip 7 sends the positioning device to the cloud processor 1 .

[0044] : The wheelchair 3 is also provided with a user port 12, the cloud processor 1 sends the positioning to the user port 12, and the user selects the drone 2 through the user port 12.

[0045] The drone 2 and the wheelchair 3 are provided with a wireless device 13 , and when the drone 2 arrives at the user's location, the drone 2 and the wheelchair 3 are associated through the wireless device 13 .

[0046] Specifically, the cloud processor marks the position of the drone 2 on the electronic map according to the positioning of the positioning device 12 of the drone 2, and synchronizes it to the processing device 4, and the processing device 4. The electronic map is displayed through the user port 12, and the user can select a drone th...

Abstract

The invention relates to an intelligent cloud simulation obstacle avoidance system for a wheelchair. The system comprises a cloud processor, a drone and the wheelchair, the wheelchair comprises a processing device, a driving motor and a first camera, and the drone comprises a CPU chip and a photography device; the cloud processor, the processing device and the CPU chip are in data synchronization,the cloud processor comprises a three-dimensional real-scene simulation module and a calculation module, the cloud processor judges whether or not reversing is needed according to the size ratio of the obstacle distance in a generated three-dimensional real-scene simulation graph to the preset distance, and if yes, the driving motor is driven to control the wheelchair to reverse. According to theintelligent cloud simulation obstacle avoidance system for the wheelchair, three-dimensional real-scene is processed through the cloud processor, the first visual angle of a user is simulated to a great extent, obstacle judgement and distance calculation are conducted according to the simulated first visual angle, and accordingly obstacle avoidance can be conducted more effectively.

Description

technical field [0001] The invention relates to an obstacle avoidance system, in particular to a cloud simulation intelligent obstacle avoidance system for wheelchairs. Background technique [0002] With the development and progress of social civilization, ensuring and improving the quality of life of vulnerable groups such as the elderly and the disabled has received more and more attention from the society. A large number of studies have shown that effectively enhancing the mobility of the elderly and the disabled not only facilitates their daily life, but also has a profound impact on their mental health, self-evaluation, and mental state. Therefore, a kind of walking-replacing wheelchair that provides convenience for above-mentioned crowd arises at the historic moment. Traditional wheelchairs are manual, and people turn the handwheels to advance, which requires a lot of physical strength and is not suitable for the elderly and disabled people. Nowadays, there are elect...
