Problems solved by technology

[0004] 1. The construction cost of the system is very high;
[0005] 2. The maintenance cost of the system is very high, and the stop signs are easy to be damaged and stolen
Based on the above situation, it is difficult to promote electronic stop signs, and it is difficult to adapt to the needs of intelligent public transportation

Embodiment Construction

[0037] Such as image 3 Shown, the system workflow of the present invention is as follows:

[0038] 1. For example (3-1), in the early stage when the system is put into use, the bus (2-3) repeatedly collects a large amount of arrival time data through the RFID reader (2-4) within a certain long enough period of time . The arrival time data specifically includes: year, month, day, week, hour, minute, second, and identification number of the bus shelter.

[0039] 2. Such as (3-2), after the server receives the above data in any form, it analyzes it through data mining methods, and calculates the distance between adjacent stations of the bus (2-3) on its route Time statistics delta. data delta is an array. Suppose there is station A on the route 1 , A 2 , A 3 ,...,A n , the arrival time at each station is t 1 , t 2 , t 3 ,...,t n , then there are:

[0040] delta = {d 1 , d 2 , d 3 ,...,d n}

[0041] ={t 1 , t 2 -t 1 , t 3 -t 2 ,...,t n -t n-1}

Abstract

The invention discloses a system for forecasting and inquiring the real time status of a bus. The system comprises a bus destination station information acquisition module, a bus message processing module, a server message processing module, a wireless communication module and an inquiry service module. The bus destination station information acquisition module acquires data through the RFID technique (radio frequency identification technique); the server message processing module forecasts the destination station time of the bus through the data excavating technique, and obtains the original 'Forecasting time table of the bus'; the bus message processing module and the server message processing module communicate through the wireless communication module, and update the 'Forecasting time table of the bus' periodically, so that the forecasting data provided by the system is more accurate and reliable. The invention provides the system for inquiring the real time status of the bus, which has low cost and is easy to popularize, so that citizens can conveniently take buses, thereby further improving the service quality of urban bus operation, and improving the urban image.

Description

technical field [0001] The invention relates to the technical field of intelligent public transportation, in particular to a system for predicting and querying the real-time status of public transportation. Background technique [0002] Radio frequency technology (RFID technology) refers to the use of radio frequency for non-contact communication to achieve the purpose of identifying and exchanging data. RFID technology has the following advantages: no need for contact and manual intervention, it can work in harsh environments, it can identify high-speed moving objects, and it can identify multiple targets at the same time, and the operation is convenient and fast. With the continuous maturity and development of this technology, radio frequency technology has been popularized and promoted rapidly, and has been widely used in logistics, retail, manufacturing, clothing industry, medical treatment, identification, anti-counterfeiting, library and transportation and other fields...
