    Abstract: The present disclosure provides a method and apparatus for providing an automated interlocking logic for moving-block railway signaling. According to at least one embodiment, the present disclosure provides a method for generating a train route for railway signaling based on moving block principle, including generating a directed graph for a track layout by calling pre-stored track information, generating a path matrix corresponding to the number of movement hops of a train based on the directed graph, and generating a train route from the path matrix, and verifying the train route by obtaining route information of the train from a mission of an automatic train supervision (ATS) system and comparing the route information with the train route.

    Abstract: The present disclosure relates to a contactless charging device and a contactless charging method using the same, and particularly, to a location zone-based contactless charging device and a contactless charging method using the same that enable multiple passengers to be charged simultaneously in a one-by-N format without a need for direct tagging of a vehicle terminal, by utilizing a step sensor built into a passenger terminal. The present disclosure may accurately and automatically perform the charging without the terminal tag even when multiple passengers board and alight at the same time, such as in the tram, thereby reducing a boarding and alighting time and providing convenience and safety to the passengers. In addition, the present disclosure may accurately determine the boarding and the alighting of the passenger even when sensing of some beacons installed at multiple stations is uncertain or some beacons are broken, thereby improving reliability and preventing incorrect charging. The present disclosure has advantages of being economical and easy to manage and maintain because all of multiple terminals for the tag in the vehicle are able to be removed and the multiple beacons are not installed unlike in a gate zone-scheme tagless system. Furthermore, the present disclosure has an advantage of increasing the accuracy of the boarding/alighting determination by offsetting uncertainty of short-range communication without an additional cost by utilizing the built-in sensor (the step sensor) of the passenger's smartphone.

    Abstract: Provided is an energy harvester and an engine monitoring system. An engine monitoring system using an energy harvester includes at least one or more self-power generation wireless sensor nodes for generating electric energy using the energy harvester and monitoring an engine; and a management server that receives and manages sensing information received from the self-power generation wireless sensor nodes. The self-power generation wireless sensor nodes includes sensor modules monitoring the engine; a data processing unit identifying and packaging sensing information; a wireless communication unit wirelessly transmitting the packaged sensing information to the management server; the energy harvester generating electric energy to be supplied to the sensor modules, the data processing unit, and the wireless communication unit by converting vibration energy of the engine into the electric energy; and a power management unit controlling the electric energy to supply the electric energy to the sensor modules, the data processing unit.
