System and method for assisting the visually impaired in urban public transport

Abstract

A visually impaired people boarding assistance system and method for urban public transport. The system comprises an intelligent cloud platform, a vehicle-mounted blind guiding terminal, an intelligent mobile phone, a vehicle label for uniquely identifying a public transport vehicle and a station label for uniquely identifying a bus station, wherein both the vehicle-mounted blind guiding terminal and the vehicle label are mounted on the public transport vehicle, the station label is mounted at the bus station, the intelligent mobile phone is connected to the vehicle-mounted blind guiding terminal, the vehicle label and the station label in a wireless mode respectively, and the intelligent mobile phone is connected to the intelligent cloud platform in a wireless mode. In the visually impaired people boarding assistance system and method for urban public transport, an intelligent mobile phone may be adopted to read and broadcast information about a public transport vehicle and a station, public transport information is broadcast by means of a vehicle-mounted blind guiding terminal in conjunction with public transport real-time data stored in an intelligent cloud platform, and visually impaired people are led to take the public transport vehicle. The system and method have characteristics of a high degree of intelligence, low investment costs, good data stabilization and high reliability, and may be widely applied to the industry of public transport boarding assistance.

Description

technical field [0001] The invention relates to the field of information navigation technology, in particular to a system and method for assisting the visually impaired in urban public transport. Background technique [0002] At present, the number of visually impaired people in China is more than 7 million, accounting for 18% of the total number of visually impaired people in the world. In addition, there are about 12 million people with low vision in the country, and the sum of the two accounts for about 1.5% of the total population of the country. This group of people is limited by economic conditions, and because the bus lines are relatively dense and bus travel is relatively affordable, most visually impaired people prefer to travel by bus, but due to limited vision, there are many inconveniences for the visually impaired to travel by bus. The visually impaired need to be accompanied by a special person and use auxiliary tools such as guide sticks and guide dogs to trav...

AI Technical Summary

Problems solved by technology

This group of people is limited by economic conditions, and because the bus lines are relatively dense, and bus travel is relatively affordable. Most visually impaired people prefer to travel by bus, but limited by their vision, there are many inconveniences in bus travel for visually impaired people.

The visually impaired need to be accompanied by a special person and use auxiliary tools such as guide sticks and guide dogs to travel. However, affected by economic and policy factors, the utilization rate of guide dogs in China is extremely low.

[0003] In terms of blind-guiding information technology and information systems, the common technologies on the market are the use of ultrasound for distance measurement and obstacle avoidance, the use of microwaves for sensing vehicles or platforms, the use of infrared for short-distance communication, and the use of custom-made handheld terminals to control vehicles to broadcast line voices, etc. , most of the information systems operate independently, unable to realize intelligent passenger assistance

Moreover, these methods have the following disadvantages: 1. Because the bus vehicles and bus lines in actual operation are dynamically changing, and the changes are quite frequent, the method of using ultrasonic distance measurement cannot adapt to the actual situation of dynamic changes, and it is easy to cause wrong guidance due to data inconsistency

2. Microwave sensing device is a special equipment, on the one hand, it has high economic cost, high construction and maintenance costs, and needs mains power supply, on the other hand, its reliability is not high

3. Infrared communication and custom-made dedicated handheld terminals are expensive and difficult to promote and use. With the development and application of smart phone terminals, this method has gradually been eliminated

4. Most of the existing ride-assistance systems are closed systems, which can only provide partial services for visually impaired users, and cannot be expanded to apply to ordinary bus traveler information services, bus industry management, bus enterprise operations and other fields, and the audience is narrow , high operation and maintenance costs

In general, the current ride-assistance solutions have disadvantages such as low intelligence, high cost, poor data stability, low reliability, poor scalability, and poor sustainable operation capability.
