Early warning system for arrival of bus

Abstract

The invention provides an early warning system for the arrival of a bus, comprising an initial station waiting hall, a terminal station waiting hall, a plurality of buses travelling between the initial station waiting hall and the terminal station waiting hall and a plurality of first direction waiting halls and second direction waiting halls which are respectively arranged on two sides of a position between the initial station waiting hall and the terminal station waiting hall; the initial station waiting hall and the terminal station waiting hall are respectively provided with intelligent code converters; a radio frequency identification device (RFID) wireless transmitter is arranged on each bus; first direction wireless receivers and second direction wireless receivers for receiving signals transmitted by the RFID wireless transmitters are respectively arranged in the first direction waiting halls and the second direction waiting halls; and the first direction wireless receivers and the second direction wireless receivers are respectively and electrically connected with an early warning device of a bus stop platform. According to the invention, by adopting the RFID technology to realize the wireless transmission of the signals and using a code identification technology to ensure the accurate mutual identification between the bus and the bus stop platform, the whole system is more humanized and the travel is safer.

Description

technical field [0001] The invention relates to the technical field of public transportation, in particular to a vehicle arrival forecast system in advance. Background technique [0002] Bus transportation plays a very important role in short-distance transportation, especially in urban public transportation. Most urban residents rely on buses to travel in their daily lives, such as students going to school and citizens going to work. The current buses are equipped with station announcement devices, but the disadvantage is that the driver needs to manually control the station announcement, which is very inconvenient to operate, and may miss or report the wrong station, and may even distract the driver's attention and cause traffic accidents. ACCIDENT. In addition, the current bus stops (that is, bus shelters) are quite simple, and there is no vehicle arrival forecast device installed in advance. Waiting passengers often do not know when the bus they want to take will come, ...

AI Technical Summary

Problems solved by technology

However, a careful analysis of the existing proposed schemes shows that they are only in the hypothetical stage, and many key issues have not been solved.

Wherein the most important problems are as follows, the first, most of the existing buses are used for round-trip transportation, and the driving routes are generally the same, but in opposite directions, and the bus stops are usually built obliquely to each other, and the positions are very close. The station name is also usually the same, and the existing technology has not yet solved how the bus automatically recognizes the platform of the departure direction and the platform of the return direction at the same position; Not far away, especially when encountering a turning, the straight-line distance between the bus stops is even closer. The prior art has not solved how to accurately identify the bus when the transmitter signal in the bus covers multiple different bus stops The next bus stop to be reached; third, because the routes of the buses are different, the same bus stop may be in the direction of departure for the bus of a certain line, while the bus of another line may be in the departure direction. It may be in the direction of return, how to make the bus stop accurately identify its own direction, and no effective solution has been proposed in the prior art
