Beidou continuously operating reference station (CORS) compatible bus precise positioning system and working method thereof

Abstract

The invention relates to a Beidou continuously operating reference station (CORS) compatible bus precise positioning system. The Beidou continuously operating reference station (CORS) compatible bus precise positioning system includes a Beidou CORS compatible bus precise positioning terminal, a CORS positioning system, a communication service center and a bus background management system; the Beidou CORS compatible bus precise positioning terminal includes a CPU module, a power source module, a Beidou / GPS dual-mode positioning module, an inertial navigation positioning module, a 3G / 4G communication module, a touch screen display module and a storage module; and the CORS positioning system includes a base station, a data processing center and a communication gateway 1. According to the Beidou continuously operating reference station (CORS) compatible bus precise positioning system of the invention, the GPS and the CORS are combined together, and therefore, the effectiveness and integrity of the system can be improved; the defect of incapability of performing position when a bus enters a GPS blind area can be eliminated, and vehicle real-time accurate positioning can be realized, and positioning accuracy can reach a centimeter level; accurate positioning data which are obtained in real time are transmitted to a background management center so as to be stored, and therefore, reliable data can be provided for the generation of bus roads.

Description

technical field [0001] The invention relates to a precise positioning system for buses compatible with Beidou CORS and a working method thereof, belonging to the technical fields of intelligent transportation and Beidou / GPS positioning. Background technique [0002] In the development and construction of urban intelligent public transport, especially in the fields of real-time positioning, dynamic monitoring, and dispatch management of buses, GPS has become one of the key technologies for building urban intelligent public transport. However, the current application of GPS positioning technology in the field of intelligent public transport is still There are deficiencies. Due to the influence of various factors in the system and measurement, the current bus GPS positioning accuracy error is generally in the range of several meters or even tens of meters. Therefore, it is impossible to accurately determine whether the bus is driving on the bus lane or whether the bus has arriv...

[0002] In the development and construction of urban intelligent public transport, especially in the fields of real-time positioning, dynamic monitoring, and dispatch management of buses, GPS has become one of the key technologies for building urban intelligent public transport. However, the current application of GPS positioning technology in the field of intelligent public transport is still There are deficiencies

Due to the influence of various factors in the system and measurement, the GPS positioning accuracy error of the current bus is generally in the range of a few meters or even tens of meters. Therefore, it is impossible to accurately determine whether the bus is driving on the bus lane or whether the bus has arrived at the stop.

Due to the large positioning error of the existing device, the analysis of the driving behavior of the bus driver cannot be satisfied, the early warning of the deviation from the bus road, the accurate calculation of the driving time, driving location and mileage of the bus section, and the establishment of an accurate model of the operating mileage and fuel consumption , cannot become an effective basis for the public transport management department to conduct vehicle scheduling and management
