Embodiment 1

[0141] Embodiment 1 A Multifunctional Intelligent Wheelchair Control System

[0142] Such as Figure 1-Figure 3 As shown, this embodiment includes a UWB indoor positioning subsystem, an intelligent mobile terminal, a walking drive device installed on an intelligent wheelchair, a control unit 8, a data transmission module, a scene information detection device, an operating device 1, an audible and visual alarm device, and a gyro Instrument 15, pressure sensor 4 and obstacle driving mechanism.

[0143] Such as Figure 4 As shown, the UWB indoor positioning subsystem includes several positioning base stations set in the building to be navigated and positioning tags installed on the smart wheelchair.

[0144] The control unit 8 drives the intelligent wheelchair to advance through the walking driving device. The walking driving device includes the hub motor of the driving wheel and the steering stepper motor 6. The control unit 8 is connected with the hub motor of the driving whe...

Embodiment 2

[0153] Embodiment 2 A control method of a multifunctional intelligent wheelchair

[0154] This embodiment adopts embodiment 1 to realize, such as Figure 8 As shown, this embodiment is carried out according to the following steps in sequence:

[0155] 1. Calibrate the coordinates and world coordinates of the UWB indoor positioning subsystem

[0156] The user first calibrates the coordinate system of the UWB indoor positioning subsystem and the world coordinate system through the smart wheelchair client to realize the unification of the coordinate system of the UWB indoor positioning subsystem and the world coordinate system;

[0157] 2. Create an interior floor plan

[0158] The mobile smart client uses the built-in tools to construct the indoor floor plan under the unified coordinate system;

[0159] The floor plan includes the location and size of indoor furniture, doors and windows, and preset coordinate points in the room;

[0160] The preset coordinate point refers to...

Embodiment 3

[0172] Embodiment 3 A collision avoidance processing method for a multifunctional intelligent wheelchair

[0173] In Embodiment 2, in step 4, during the process of traveling to the target location, the 360° laser scanning radar scans the environmental information in real time and feeds it back to the control unit 8. If a "real obstacle" is detected and the obstacle distance is less than the wheelchair alarm value, Then the control unit 8 carries out "collision avoidance processing" and sends an alarm through the alarm device at the same time; Obstacles to be crossed or climbed over.

[0174] Such as Figure 11 As shown, "collision avoidance processing" is carried out in the following order:

[0175] S1, in the process of advancing, the 360 ​​° laser scanning radar scans the surrounding environment in real time and sends the angle and distance value between the measured point distance and itself to the control unit 8;

[0176] S2. After data processing, the control unit 8 pe...

Abstract

The invention discloses a multifunctional intelligent wheelchair control system. The multifunctional intelligent wheelchair control system comprises a UWB indoor positioning subsystem, an intelligentmobile terminal, a traveling driving device mounted on an intelligent wheelchair, a control unit, a data transmission module, a scene information detecting device, an operating device, and a sound andlight alarm device; the UWB indoor positioning subsystem comprises a plurality of positioning base stations arranged in ato-be-navigated building and a positioning tag mounted on the intelligent wheelchair; the control unit drives the intelligent wheelchair to travel through the traveling driving device, and a GPS / Beidou positioning moduleis integrated in the data transmission module. The invention further discloses a control method for a multifunctional intelligent wheelchair. According to the multifunctional intelligent wheelchair control system and the control method for the multifunctional intelligent wheelchair, convenient navigation service can be provided for a user, the advantages of having high integration degree, small volume, light weight, low cost, convenient mounting, and simple operation are obtained, and the multifunctional intelligent wheelchair control system and the control method for the multifunctional intelligent wheelchairare applicable to the technical field ofmedical care devices.

Description

technical field [0001] The invention belongs to the technical field of medical care equipment, and is used to meet the needs of people with disabilities, in particular to a multifunctional intelligent wheelchair control system and a corresponding control method. Background technique [0002] Wheelchairs are divided into electric and manual folding wheelchairs. They are important mobile tools for home rehabilitation, turnover transportation, medical treatment, and outing activities for the wounded, sick, and disabled. It is convenient for family members to move and take care of patients, so that patients can use wheelchairs to exercise and participate in social activities; [0003] With the advancement of science and technology, people have developed smart wheelchairs with multiple functions to adapt to different application scenarios, such as navigation, collision avoidance and other functions. However, existing electric wheelchairs or smart wheelchairs still have deficienc...
