A digital bus system based on private SMS communication and its working method

Abstract

The present invention a digital public transportation system based on the dedicated short-range communication and a working method. The system comprises at least one on-board information device mounted on a bus, at least one electronic bus station and an information management system. The electronic bus station exchanges information with the on-board information device via a dedicated short-range communication network to record bus arrival information, which is then sent to the information management system for processing via a wireless communication network; and the information management system comprising at least one data processing unit collects and stores the realtime information of the bus, processes the received arrival information sent by the electronic bus station, calculates the estimated time when the bus arrives every electronic bus station ahead and generates arrival forecast information, which is then sent to every electronic bus station ahead for display via the wireless communication network. The present invention uses the mature and stable DSRC wireless short-range communication technology and accurately forecasts the arrival of the bus, the stability of the system is good, and the cost of construction is low.

Description

technical field [0001] The present invention relates to a digital public transport system, in particular to a system using dedicated short-range communication (DSRC: Dedicated Short Range Communication) technology, communication network technology, multimedia display interaction technology, GIS (Geography Information System; geographic information system) geographic information technology and computer network technology A digital public transport system based on dedicated short-range communication and its working method that integrates various elements of urban public transport, namely passengers, buses, platforms, lanes, signals, capacity, and scheduling, into a unified intelligent monitoring and management platform. Background technique [0002] At present, public transport has become an indispensable part of people's lives, and the traffic situation has attracted more and more attention. As the main tool for urban residents to travel, buses have always been expected for t...

Problems solved by technology

[0006] Although the GPS system solves some problems in the prior art, the GPS system also has the following defects: especially when used in a high-rise environment, the signal is unstable, and it is impossible to make accurate measurements due to the influence of transmission delay and canyon effect. Forecast, the error is large; due to the canyon effect is often interrupted, it will take a certain period of time to synchronize after the interruption, resulting in system instability; the positioning accuracy is low, about tens of meters; the construction cost and maintenance cost are high; the vehicle equipment needs to communicate with the background management center frequently, cause high operating costs

[0007] In addition, the system is even more difficult for some special passengers, such as non-local passengers who are not familiar with the local geographical location, disabled people such as the blind, etc., to grasp bus information, which makes it very inconvenient for such special groups of people to travel by bus
