Abstract: There are provided a system and a method for controlling power of a high speed vehicle. The system for controlling power of a vehicle includes: a latch relay configured to supply power to a vehicle load or to block power to the vehicle; a communication part configured to output a driving signal when a wakeup signal is received; a pulse generator configured to output a one shot pulse that turns on the latch relay when the driving signal is applied; and a processor configured to control a driving of the latch relay turned on by the one shot pulse when being initialized.

Abstract: A vehicle communication system includes at least one vehicle controller configured to control functions of a vehicle and configured to output data related to the vehicle. A communication unit is configured to transmit the data output from the vehicle controller to an external data collecting device. A memory is configured to store the data. A network managing unit is configured to control the communication unit to output the data to the data collecting device when the data is different from previous data transmitted to the data collecting device.

Abstract: A method and apparatus for collecting vehicle data is provided. The method for collecting vehicle data in a vehicle data collection server communicating with a vehicle through a wireless network includes receiving vehicle data corresponding to first to Nth data items from a first vehicle. When alternative data collection vehicles are needed, the method searches for the alternative data collection vehicles in a group of vehicles, for each of the first to Nth data items, receives vehicle data corresponding to at least one of the first to Nth data items through the searched alternative data collection vehicles, and stores the vehicle data received from the first vehicle and the vehicle data received from the alternative data collection vehicles.

Abstract: A charging device of a welding fixture of spacer grid comprises a base frame; a conveyor for conveying a welding fixture horizontally over the base frame; and a gripper located over the base frame for gripping a welding fixture conveyed along the conveyor to charge a welding fixture into a welding chamber, wherein the gripper comprises a gripper body; and a gripping part installed horizontal to the end of the gripper body for gripping a welding fixture and capable of tilting in vertical direction to the gripper body in case more than a predetermined load is applied as a vertical load.
