Control system and method of intelligent wheelchair

[0059] Example 1

[0060] combine figure 1 The human-computer interaction control subsystem of the intelligent wheelchair control system of the present invention is described.

[0061] like figure 1 As shown, the human-computer interaction control subsystem of the intelligent wheelchair control system of the present invention includes a sensor module, a single-chip microcomputer, a mobile terminal and a data processing cloud terminal. The sensor module is used to collect training data of the user. The voltage signals collected by each sensor are amplified by the amplifier circuit and then transmitted to the A/D conversion module, and then input into the single chip microcomputer. The single-chip microcomputer sends the training data collected by the sensor to the mobile terminal, and the mobile terminal sends the collected training data to the data processing cloud terminal through the wireless network. The data processing cloud terminal performs data processing on the received training data. Specifically, data processing includes: using expert knowledge bases to recommend exercise plans, real-time adjustments to exercise plans, and/or updating personalized exercise plans using machine learning methods. The data processing cloud terminal feeds back the data information it provides to the mobile terminal. Specifically, after data processing, the data processing cloud terminal can provide at least data information including training progress and training suggestions.

[0062] Users can also adjust the plans and/or programs recommended by the system through the mobile terminal, so as to form a training program suitable for them. The mobile terminal also manages whether the daily training plan is executed, and monitors each training situation. Specifically, after a training session is completed, the mobile terminal sends the monitored training data to the data processing cloud terminal. The data processing cloud terminal analyzes the data and gives an overall score for the training, and displays the result on the screen through the mobile terminal. For the convenience of the user, the user can also control the power supply of the wheelchair main body through the mobile terminal, so as to choose a suitable training method for the user.

[0063] Example 2

[0064] combine figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 and Figure 7 The wheelchair motion control subsystem of the intelligent wheelchair control system of the present invention is described.

[0065] The wheelchair motion control subsystem of the intelligent wheelchair control system of the present invention at least includes a wheelchair main body. like figure 2 and image 3 As shown, the wheelchair main body includes the following structures: driving wheel 1, vehicle frame 2, driven wheel 3, pedal 4, elastic connector 6, seat cushion 7, clutch button 9, terminal support frame 10, armrest 11, backrest 13, card Buckle 14, protective shell 16, handle 17, transmission chain 18, driving rod 19, support frame 20, baffle plate 21, servo motor 22, manual wheel 23, handbrake 24, battery 25 and clutch 26.

[0066] When the user uses the wheelchair main body of the present invention to assist in completing the sit-up training, the user needs to fix himself on the backrest 13 through the buckle 14 . At the same time, the user tightens the hand brake 24 to fix the wheelchair, and presses the clutch button 9 to make the clutch slide to the "training" gear. Drive support frame 20, thereby can drive backrest 13 along Figure 4 , Figure 5 , Image 6 and Figure 7 The backrest 13 shown reciprocates from the first position to the fourth position. The trajectory of the reciprocating motion simulates the posture trajectory of the waist when a healthy person stands up, so it can help the user to achieve the same standing action as a healthy person.

[0067] When the wheelchair needs to move, the user can turn on the handbrake 24 and press the clutch button 9, so that the clutch slides to the "moving" gear, and the servo motor 22 drives the driving wheel 1 to rotate, so that other assistants can push the wheelchair forward through the handle 17 , or the user moves forward through the manual wheel 23. When the wheelchair moves, the driven wheel 3 can rotate, and the wheel fork fixed thereon can change direction left and right, so that the wheelchair moves forward according to the designated route. When needing wheelchair to stop, only need handle brake 24 brake tight.
