<p>PROBLEM TO BE SOLVED: To properly calculate a fare by administrating the loading history of passengers on a system side and surely understanding the loading history, even if system errors occur. SOLUTION: A vehicle server 14 is installed in each train, and a station server 12 is installed in each station. A loading history database 26 and a through-station database 28 are installed in a center server 10 connected to the station server 12. The station server 12 samples the data on the entry and exit station, and the vehicle server 14 samples the data on the loading on the train. Based on the data acquired by each server, a loading history transaction is generated and made to communicate between the servers to record in the database for each server. The center server 10 calculates the fee of passenger, based on the loading history data and the through-station databased on the loading history transaction.</p> |
