Abstract:
The present invention relates to a device and method for controlling a platform crossing gate wherein in the state where a passenger moving passage along which passengers cross the rail road is built on the center of the station or on both sides of a platform of the station for metropolitan subways or light rails and a gate is built to stop the trains and the passenger movement before the crossing section of the passengers, crossing start time point is calculated within the remaining crossing time in consideration of the stop time of the current trains and the arrival time of next trains and the gate is open in accordance with the calculated results to allow the passengers to safely cross the rail road. According to the present invention, the device for controlling a platform crossing gate includes: a gate operating part for operating a gate to open or shut off the gate; a stop sensing part for sensing whether trains enter and stop the rail road of the platform in the station; a controller for controlling the gate operating part after counting 20 seconds as mean stop time if the stop of the trains is sensed and to allow the gate to be open for 14 seconds or more as minimum crossing time within 80 seconds as the remaining crossing time and to allow the gate to be shut off again; a train information storing part for storing the train running information taken from the outside as data to calculate the time on which the trains enter the rail road within the platform of the station; and a communication part for communicating with the outside to take the train running information from the outside.
Abstract:
Provided is an emergency driving mode approval apparatus comprising: a transmit unit which is installed in a train to transmit an approval request signal for emergency driving mode to a central control center; a manage unit which is installed in the central control center to receive the approval request signal transmitted from the transmitter unit, sound an alarm to the central control center, and transmit an emergency driving mode approving signal to the train; a receive unit which is installed in the train to receive the emergency driving mode approving signal; and a control unit which is interlinked with the receive unit and has a function allowing a driver to switch a driving mode into an emergency driving mode if receiving the emergency driving mode approving signal from the receive unit and to release the emergency driving mode during emergency driving. According to the present invention, an approval procedure for an emergency driving mode is carried out systematically for raising attentiveness of a manager and a driver when switching into the emergency driving mode. In addition, an accident prevention effect can be expected since the emergency driving mode is notified to a driver's cab by an alarm.
