Abstract
Description
The present invention relates to a train operation device using DGPS and a railway vehicle including the same, and more particularly, to a train operation device using a DGPS that corrects a position error of a signal device, a vehicle propulsion force and a vehicle time using DGPS position information, Vehicle.
In the railway system, the location of the vehicle was tracked to obtain accurate location information, and the driving schedule of the vehicle was established using the location information or the driving force of the vehicle was adjusted.
Conventional railway vehicles track the position of the vehicle by using tag attached to the railway or by using cumulative distance. However, this method can present relative position coordinates, but it can not provide absolute position coordinates that can be verified as universally as GPS.
In addition, using the GPS, the moving path of the railway vehicle can be reproduced in real time in the 3D absolute coordinate system, and the absolute coordinates can be confirmed not only in the railway vehicle but also in the control center.
Therefore, although there are many ways to track the position of railway vehicles using GPS in railway vehicles field, the position accuracy is not excellent due to the use of a single GPS or information corrected by the receiver.
The present invention can provide a train operation device using DGPS and a railway vehicle including the DGPS, which corrects a position error of a signal device, a vehicle propulsion force and a vehicle time using DGPS position information.
The DGPS train navigation apparatus receives the ground information about the vehicle operation and collects the position information on the line, and receives the first GPS position information from the control apparatus that receives the GPS data of the first satellite An on-vehicle signal device for receiving; And receives GPS data of the second satellite and collects second GPS position information, receives the position information on the line and the first GPS position information from the onboard signal device, and receives an error component of the second GPS position information And calculates a DGPS position information of the vehicle by comparing the position information on the line with the DGPS position information and transmitting the calculated distance error component to the onboard signaling device.
Here, the on-vehicle signal device may receive a distance error component from the integrated train control device and correct position information on the line.
Also, the onboard signaling apparatus may correct the position information on the line if the distance error component exceeds a predetermined error range.
In addition, the train comprehensive control device may calculate the speed information and the distance information of the vehicle from the DGPS position information, and output the speed information and the distance information of the vehicle to the driving system of the vehicle so as to correct the driving force of the vehicle .
In addition, the train comprehensive control device may collect GPS time information from the second GPS position information, output the GPS time information to the vehicle, and synchronize the time with the set period.
Also, the train comprehensive control device may further include: a GPS receiving unit for receiving GPS data of the second satellite; A communication unit for performing communication with the onboard signal device; And an arithmetic unit for calculating the DGPS position information by deleting an error component of the second GPS position information.
Also, the calculating unit may calculate the DGPS position information using one error estimation method of a single difference and a double difference.
The railway vehicle according to an embodiment of the present invention may include the above-described train driving apparatus using the DGPS.
The present invention can provide a train operation device using DGPS and a railway vehicle including the DGPS, which corrects a position error of a signal device, a vehicle propulsion force and a vehicle time using DGPS position information.
