Vehicle mounted terminal and public transportation system containing the vehicle-mounted terminal

Abstract

The invention discloses a vehicle-carrying terminal, which comprises the following parts: wireless short-path communicating unit, which transmits data with other wireless short-path communicating equipments within communicating scale; main control unit, which controls wireless short-path communicating unit to transmit data with other mated wireless short-path communicating equipments. The invention can realize entire gathering for vehicle driving information and ensure reliable data for vehicle dispatching working, which promotes station under inferior GPS signal. The terminal provides convenience for passenger, which also contains public transport system with the vehicle-carrying terminal.

Description

technical field [0001] The invention relates to the field of transportation, in particular to the field of public transportation. Background technique [0002] In the prior art, the implementation of the intelligent public transportation system is mostly through the combination of GPS (Global Positioning System, Global Positioning System) and GPRS (General Packet Radio Service, General Packet Radio Service). Among them, the GPS part is used to realize the function of automatic station reporting and positioning, and the GPRS part is used to upload the collected vehicle data and real-time position of the vehicle to the background server for processing, so as to realize the monitoring and dispatching functions of public transport vehicles. [0003] But, a very serious problem in above-mentioned prior art is exactly: because the signal of GPS is not good, can't carry out automatic station reporting and also can't obtain the information of positioning, similarly, problems such as...

AI Technical Summary

Problems solved by technology

[0003] But, a very serious problem in above-mentioned prior art is exactly: because the signal of GPS is not good, can't carry out automatic station reporting and also can't obtain the information of positioning, similarly, problems such as the coverage of GPRS network and dropped line also very easily cause The uploaded information is incomplete, so that effective monitoring cannot be carried out, and it may also cause wrong scheduling

[0004] The reason is that there are many high-rise buildings and viaducts in the city now, and the existence of these high-rise buildings and viaducts can easily lead to extremely weak GPS signals in certain locations, and then cannot perform GPS functions.

Similarly, the above-mentioned reasons will also cause the GPRS network coverage in some places to be affected or the signal strength is very weak, and then the normal transmission of GPRS cannot be realized; on the other hand, due to more and more people using mobile phones, mobile base stations can The number of communication with the mobile terminal is limited, so it is very easy to use GPRS transmission or transmission drop due to the busy network, so that the GPRS part cannot work normally
