Embodiment Construction

[0025] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0026] An intelligent control system for an electric wheelchair, such as figure 1 As shown, it includes ARM main control module, joystick, electronic compass, long-distance wireless communication module, ranging module group, DSP motor control module and motor drive module. The control system takes the ARM main control module as the core. On the one hand, the ARM main control module is connected to a touch LCD screen through the I / O interface to realize the human-computer interaction function. On the other hand, the ARM main control module communicates with the electronic compass according to the CAN2.0 protocol. , remote wireless communication module, two distance measuring module groups, and DSP motor control module are connected to form a one-to-many CAN network, and the joystick is connected to the CAN network as a node device independent of th...

Abstract

The invention relates to an intelligent control system of an electric wheel chair, comprising an ARM (Automated Route Management) master control module, an operating handle, an electronic compass, a remote wireless communication module, a distance measuring module group, a DSP (Digital Signal Processing) motor control module and a motor driving module, wherein the ARM master control module is connected with the electronic compass, the distance measuring module group and the DSP motor control module through a CAN (Controller Area Network) bus to form a one-to-many CAN network; as node equipment independent from the ARM master control module, the operating handle is accessed to the one-to-many CAN network; the DSP motor control module is connected with DC driving motors through the motor driving module; and each DC driving motor is provided with a photoelectric encoder and forms motor rotating speed closed-loop control. The invention realizes the intelligentized control function of the electric wheel chair and ensures the instantaneity, the extendibility and the portability of the intelligent control system by adopting an embedded type system and modular design and has rich functions, flexible control, convenient use, and the like.

Description

technical field [0001] The invention belongs to the field of electric wheelchairs, in particular to an intelligent control system for electric wheelchairs. Background technique [0002] The increasingly serious social problems of aging and the increase in the proportion of the disabled in the total population have made the daily self-care of the elderly and the disabled a major social problem that has to be faced at present. With the development of science and technology, the emergence of advanced means of transportation is gradually improving their quality of life, and electric wheelchairs are one of the important ones. Due to the special circumstances of the elderly and the disabled, higher requirements are placed on the intelligent control of electric wheelchairs. Electric wheelchairs usually use a DC motor as the transmission unit, and the movement functions such as forward, backward, radius turning and stop of the electric vehicle are realized by controlling the joysti...
