a method for estimating the location of urban railway using real-time location information

摘要

The present invention relates to a train location information derivation method using the real-time train location signal data of the urban railway; If the station and history are traveling, estimating where the train is located using the time the train left the station and the average time the train traveled to the next station to solve where the train is located. In order to solve the problem of train movement in case of signal disconnection where the position signal data of some trains are not received, the city train real-time train position signal data is corrected to correct the error value when the delay time due to the data reception time delay occurs. It provides a method for deriving the used train location information. The present invention includes the steps of: (a) receiving train signal data sensed in real time during the movement of the train running the route from the signal detector on the train rail; (b) comparing whether the train signal data received in real time is an arrival signal; (c) when the train signal data is determined to be an arrival signal, accumulating travel time information of a train moving between a station and a station, generating average travel time and average travel time data, and storing the data in a database; (d) comparing whether the train signal data is a departure signal if the arrival signal is not an arrival signal; (e) If it is determined in step (d) that the train signal data is a start signal, it is predicted at which point the current train position is located according to the average time and time it takes to move from the train departure to the next station. Estimating a real time train location; (f) comparing whether a difference in a signal interval between the received real-time train signal data and the preceding train is equal to or less than a setting step; And (g) a real-time train position correction step of predicting a position of a train whose signal is disconnected when the difference between the signal train received in the step (f) and the signal interval between the preceding train is determined to be less than or equal to the setting step. Provided is a method for deriving train location information using real-time train location signal data of an urban railway.
