Electric wheelchair with automatic return function

Abstract

The invention discloses an electric wheelchair with an automatic return function, and further discloses an automatic return method for the electric wheelchair. The electric wheelchair comprises an MCUcontroller, a GPS / BD satellite positioning module, a NB-IoT wireless communication module, an acceleration sensor, a power supply module, an electric wheelchair control module, a memory, a cloud platform and an automatic travelling module. The MCU controller is connected with the GPS / BD satellite positioning module, the NB-IoT wireless communication module, the acceleration sensor, the electric wheelchair control module, the power supply module, the memory and the cloud platform. The MCU controller collects and processes satellite position information obtained by the GPS / BD satellite positioning module, base station auxiliary positioning information obtained by the NB-IoT wireless communication module and acceleration information obtained by the acceleration sensor to obtain current position information of a positioning terminal, and then the current position information is transmitted to the far-end cloud platform through the NB-IoT wireless communication module; and after the cloudplatform receives an automatic return instruction, the instruction is issued to the MCU controller, and the automatic return movement is achieved by issuing instructions to the electric wheelchair control module and the automatic travelling module through the MCU controller. The electric wheelchair with the automatic return function has the advantages that quite comprehensive indoor cellular dataconnection coverage can be provided, the ability of supporting mass connection is achieved, power consumption is lower, the standby time is longer, automatic return, real-time positioning and real-time monitoring of the travelling trajectory and battery electricity-quantity information are achieved.

Description

technical field [0001] The present invention relates to the field of positioning terminal device technology and medical equipment, in particular to an electric wheelchair with automatic return based on GPS / BD satellite navigation and NB-IoT precise positioning technology. Background technique [0002] The positioning device is generally used for the positioning of children and the elderly and the anti-lost of pets. Existing portable positioning devices generally realize the geographic location positioning function by installing GPS modules, GPRS modules and Bluetooth modules. The circuit structure is relatively complicated, the data communication is relatively complicated, the power consumption is relatively large, and the cost is relatively high. Although the Bluetooth module can solve the power consumption problem, it cannot realize long-distance positioning due to the limitation of transmission distance. Generally speaking, the above modules are not well accepted by user...

Problems solved by technology

[0006] Wheelchairs are relatively advanced tools used for the transportation of the disabled. In the past, it was inconvenient for the disabled to travel, and they could only rely on crutches to travel. Because the use was too wasteful, they could not achieve long-distance transportation. With wheelchairs, especially electric wheelchairs, the disabled It is convenient to travel, and the travel distance has become farther

However, the current electric wheelchairs on the market do not support the Internet of Things function, that is, they cannot realize real-time positioning and data monitoring of wheelchairs. Therefore, we need to implement a new type of wheelchair with wireless positioning functions to facilitate the management of disabled people and their families , in case of an emergency, the wheelchair user or his family members can remotely control the electric wheelchair to return home with one key through the cloud platform
