System and method of helping visually impaired people take urban public buses

Abstract

The invention discloses a system and method of helping visually impaired people take urban public buses. The system includes a smart cloud platform, a vehicle blind guide terminal, a smart cell phone, a vehicle label for only identification of a public bus, and a bus station label for only identification of a public bus station. The vehicle blind guide terminal and the vehicle label are both mounted on a public bus. The bus station label is mounted at a public bus station. The smart cell phone is in wireless connection to the vehicle blind guide terminal, the vehicle label and the bus station label, and is also in wireless connection to the smart cloud platform. The smart cell phone is adopted to read and broadcast information about public buses and bus stations, and information about public buses are broadcast by the vehicle blind guide terminal by combining with public bus real-time data stored in the smart cloud platform, so visually impaired people are guided to take public buses. The system and method are high in intelligentization and low in investment and cost, exhibit good data stability and high reliability, and can be widely applied to bus-taking assistance industries.

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.
