Fixed line vehicle track monitoring system and method

Abstract

The invention discloses a fixed line vehicle track monitoring method, which comprises the steps: acquiring a line standard track corresponding to an operation line number; judging whether a vehicle running track returns to a set route in real time, and if yes, entering the next step; if a satellite signal is normal, taking satellite positioning data as a vehicle position, judging whether a vehicledeviates from the set route, if the vehicle deviates from the set route or returns, taking the satellite positioning data as the vehicle position, and if the vehicle does not deviate from the set route and does not return, correcting the vehicle position to a standard track; and if the satellite signal is abnormal, calculating the vehicle position according to the vehicle mileage and the standardtrack information, judging whether the vehicle deviates from the set route, and if the vehicle deviates from the set route, taking the satellite positioning data as the vehicle position. According tothe invention, the problem of inaccurate positioning or incapability of positioning caused by instability or shielding of satellite positioning signals is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle track monitoring and automatic station reporting on fixed lines, in particular to a vehicle track monitoring system and method for fixed lines. Background technique [0002] With the increasing traffic congestion and the advocacy of green travel, public transportation has become the choice of more and more people. In order to improve the modern management of public transportation in order to better serve the people, the monitoring of the operation trajectory of public transportation vehicles is particularly important. At present, there are mainly the following methods for obtaining the location information and driving trajectory of public transport vehicles: [0003] The first method is to use the wireless beacon device installed on the fixed equipment on the road (such as positioning piles, bus stops) for positioning. When the vehicle enters the monitoring range of the positioning pile, the curr...
