Description

Bus intelligent arrival station reminding system based on radio frequency technology

Technical field

The invention relates to the field of urban transportation services, in particular to a bus intelligent arrival-to-station reminding system based on radio frequency technology.

Background technique

RFID (Radio Frequency Identification Technology) is a non-contact, latest automatic identification technology matured in the early 21st century and is now being promoted and applied in various industries around the world. Radio Frequency Identification (RFID) is a wireless communication technology that uses radio signals to identify specific targets and read and write related data without the need to identify mechanical or optical contact between the system and a particular target. With the continuous improvement of the national economic level, the pace of urban construction is also getting faster and faster, and the use of urban public transport has largely solved the problem of traffic congestion. In order to facilitate passengers to get off the bus, most buses in the city use the voice station system, but they all use the way to the passengers of the vehicle to make the station reminder, unable to remind each passenger's specific needs, and are vulnerable to The impact of the surrounding environment makes the passengers unable to hear the reminder, and it is easy to cause the phenomenon that the reminder is not in place, which is inconvenient for passengers to travel. In order to facilitate passengers to get off the train, some vehicles also have a get-off button. When the passenger needs to get off the bus, the button is pressed to inform the driver that he needs to get off the bus. However, the button is generally only installed at the armrest of the rear door of the vehicle. When there are more passengers, it is very inconvenient for the passenger to press the button, and it is prone to wrong pressing, and the request cannot be withdrawn after pressing. It is easy for the driver to stop when the vehicle is not parked in time or when no one gets off the vehicle. The phenomenon not only wastes passenger time, but also causes inconvenience to both passengers and drivers.

Summary of the invention

The technical problem to be solved by the present invention is to provide a bus intelligent arrival-to-station reminding system based on radio frequency technology for the deficiencies in the prior art described above, which provides a station reminder according to the specific needs of each passenger and can receive passengers. The answer information, combined with the answer information of each passenger, judges and informs the driver that there is a passenger who needs to get off the train at the station, and at the same time facilitates the passenger to ride and the driver to drive.

In order to solve the above technical problem, the technical solution adopted by the present invention is: a bus intelligent arrival-to-station reminding system based on radio frequency technology, including: radio frequency bus card, first reader, second reader, third reader, processing Device, driver prompt module and station electronic tag;
