Blind guiding method and system for public transport means

Abstract

The invention provides a blind guiding method and a system for a public transport means. The system comprises a passenger side App, a vehicle-mounted intelligent terminal, a vehicle-mounted intelligent scheduling system and a cloud service platform, wherein the passenger side App is used for receiving an instruction inputted by the passenger to reserve a shuttle bus, automatically retrieving and recognizing information of a stop and a vehicle through Bluetooth beacon, communicating with the vehicle-mounted intelligent terminal and the vehicle-mounted intelligent scheduling system and giving a prompt through a voice device. through adopting GPRS positioning and Bluetooth technologies, functions of passenger traveling destination navigation, vehicle reservation and vehicle arrival prompting are integrated in a targeted mode, extra setting of a large amount of blind guiding devices is not needed, noise pollution caused by untargeted arrival voice broadcasting by the vehicle is also avoided, humanized blind guiding prompting is carried out completely according to requirements of special passengers, the accuracy is high, the passenger experience is good, and the method and the system of the invention are suitable for being used in the field of modern urban traffic.

Description

technical field [0001] The invention relates to the field of public transportation, in particular to a method and system for guiding the blind of public transportation tools designed for special passengers. Background technique [0002] Today, with increasingly developed traffic, travel is extremely difficult for the visually impaired, and vehicles are too dangerous for them. In addition, waiting for a bus at a bus stop without knowing which bus is coming is also a problem often encountered by the visually impaired. The emergence of public transport guides has undoubtedly provided great convenience for tens of thousands of visually impaired people to travel and ride. It also improves the image of the whole city and becomes a symbol of urban civilization development. [0003] According to the survey and statistics of the Qingdao Disabled Persons' Federation, the most urgent need of the visually impaired is barrier-free travel, such as barrier-free bus rides and barrier-free...

AI Technical Summary

Problems solved by technology

[0009] Disadvantages: The production cycle of Braille signs is long, the content of the instructions cannot be changed, it is difficult to identify the touch points after long-term use, the number of installation and layout points is too large, and it cannot effectively guide the visually impaired to reach the Braille signs, and the guidance method is mere formality

[0013] Disadvantages: Every bus will sign up regardless of whether there are blind friends who need to take it, which is prone to noise pollution. This method was used in Qingdao before, but it was stopped due to the problem of noise pollution in the later period. When multiple buses come into the station, the blind cannot accurately hear the progress of the bus route and know the exact location of the bus stop

[0018] 1. The signal interference and overlap are serious. The multiple Bluetooth signals on the arriving bus and the Bluetooth signal on the platform interfere with each other, resulting in problems such as simultaneous broadcasting by two vehicles and incorrect information broadcasting.

[0019] 2. Each vehicle needs to add additional system terminals, which increases the cost of installation and maintenance

[0020] 3. It is necessary to pay additional fees for the running traffic of the on-board equipment of the blind guide system

[0021] 4. The ID number of the on-board equipment of the blind guide system is bound to the license plate number, and the modification of vehicle information requires on-site confirmation, which is inefficient

[0022] 5. Bus information cannot be synchronized in real time, and there will be hidden dangers of wrong guide information

For example, if the route of the bus is changed, or the bus is scrapped or new vehicle information is added, there are hidden dangers of false positives and missed negatives.
