In view of the aging population and the increasing number of disabled people in China, our team has launched Tianxi series of human-computer interactive wheelchairs. By integrating the latest AI technology, computer-aided technology, positioning and navigation, ergonomics, robot control and other technologies, the transformation and upgrading of traditional wheelchairs have been realized. The products can realize various new functions such as multi-terrain travel, intelligent obstacle crossing, climbing within 50 degrees, intelligent monitoring and early warning, and assisting upstairs and going to bed. The three main innovations of the project products are as follows: (I) path planning system based on GPS technology and security robust design. The travel of the product is linked with the vehicle networking technology, and the GPS and navigator carried by the wheelchair are used to monitor the real-time road conditions leading to the destination by using the huge data and information in the vehicle networking. At the same time, it is equipped with a safety robust system monitoring module to mine the "invisible danger" in road traffic, and then it is processed by the system algorithm and compared with the regular database to finally obtain the optimal path planning, presented to the user (decision maker). (II) use 5G mobile communication network to connect wheelchairs with mobile phones for real-time monitoring. The product is equipped with a health and surrounding environment monitoring module, which transmits data to the communication equipment of the fixed guardian in real time through the on-board Internet of Things technology and 5G network interface. The guardian can monitor the user's physical condition and surrounding environment in real time through the health monitoring system on the wheelchair. It uses the mobile phone cloud as a data transmission and storage site, so that the mobile phone can quickly read the indicators of wheelchair monitoring, and use the mobile phone APP for real-time remote monitoring to avoid accidents. (III) original linkage telescopic arm and center of gravity adjustment mechanism coordination to achieve multi-terrain travel function. The product adopts the linkage telescopic arm and the rack and pinion transmission mechanism to coordinate the travel of the upper and lower roadsides, steps, obstacles and other terrain. Most of the wheelchairs in the market use hydraulic jack mechanism to retractor crawler for obstacle crossing. The linkage telescopic arm mechanism is simpler in obstacle crossing, lower in cost and lower in energy consumption, while the crawler obstacle crossing mechanism is heavy and complex in structure, and the linkage telescopic arm mechanism can fully load the weight of the wheelchair plus the weight of the user. In terms of project operation mode innovation, it is planned to introduce the "terminal direct sales sharing wheelchair" mode to the market, in which the terminal direct sales include "direct sales of the company's e-commerce platform and direct sales of provincial and municipal agency distributors", which can provide complete travel solutions for pension institutions, communities, medical institutions, health care institutions, etc. The team has established Shandong Tianxi Technology Co., Ltd., which is expected to occupy a certain intelligent wheelchair market within three years, drive hundreds of people to find jobs, set off an industrial revolution of "intelligent manufacturing to help the elderly and the disabled", and let technology serve the society. to provide a more intelligent and humanized way of travel for the elderly and the disabled. At the same time, in addition to the user experience advantages of product upgrades, this product also has cost advantages. In the product structure design, the unique mechanical structure independently developed by the team is adopted, which reduces the production consumables of the product. On the basis of this structure, the sensing module of the product is also simplified, thus further reducing the production cost. Compared with the electric wheelchairs ranging from 15000 to 40000 yuan/set in the existing market, the price of this product is about 10000 yuan/set, which is quite advantageous in price and has great advantages in function and user experience compared with the existing products.
