Fig. 1 is a schematic diagram of the control structure of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, an intelligent navigation wheelchair based on 5G communication comprises a wheelchair, a controller, a driving module, an operating rod, a positioning navigation module, a video acquisition module, an ultrasonic ranging module, a 5G communication module, and a safety prompt module.

The battery is installed in the wheelchair below, and drive module includes the motor, and the control end and the controller of motor are connected, realize the electronic drive of wheelchair. The operating rod is fixed on the armrest at one side of the wheelchair, so that the user can control the wheelchair to move with one hand. The positioning navigation module, the video acquisition module and the ultrasonic ranging module are fixed on the side face or the front of the wheelchair through a bracket, and the video acquisition module and the ultrasonic ranging module are installed at positions which need to avoid the shielding of the limbs of a user; the operating rod, the positioning navigation module, the video acquisition module, the ultrasonic ranging module, the 5G communication module and the safety prompt module are all connected with the controller.

The positioning navigation module is provided with a GPS or Beidou positioning chip and is provided with a display screen. The user can set navigation destinations and other operations through the touch operation of the display screen.

The video acquisition module comprises a wide-angle camera and is used for acquiring video graphic information in front of the wheelchair and transmitting acquired data to the controller in real time. The ultrasonic ranging module is used for acquiring barrier information in front of the wheelchair, and the acquired data are transmitted to the controller in real time. The controller is used for carrying out necessary communication processing on the acquired data and uploading the data acquired by the video acquisition module and the ultrasonic ranging module to the cloud computing force platform in real time through the 5G communication module. The cloud computing platform has strong computing power and a trained deep neural network model, is used for comprehensively processing original video data and ultrasonic sensing data and is used for judging road condition information in front of the wheelchair, such as obstacle information or potential road danger.

After the 5G communication module receives the road condition information in front of the wheelchair, which is fed back after the comprehensive operation of the cloud computing force platform, the controller sends a safety prompting command to the safety prompting module according to the road condition information. The safety prompting module is an operating rod vibration module or a loudspeaker installed on the wheelchair, and can prompt a user of obstacles or dangers existing on a traveling road through the vibration of the operating rod or directly sending an audio signal.
