Abstract: A chassis end plate assembly of a railway vehicle is provided, which includes an end plate; a bottom beam arranged at an inner side of a lower edge of the end plate, curved beams arranged at inner sides of two sides of the end plate, a buffer beam located above the end plate; and a reinforcing beam longitudinally arranged between the buffer beam and the bottom beam. The end plate assembly can increase the rigidity of an end portion of the vehicle and improve the vibration mode. The end plate assembly can be combined with an under-vehicle active device compartment so as to form an enclosed space, which may protect pipelines and devices under the vehicle. A railway vehicle provided with the chassis end plate assembly is further provided.

Abstract: A method for waking up wireless device includes the following concrete steps: the master device in the wireless devices contains RF transceiver module, when the RF transceiver module works at operating frequency, they are used for receiving and sending data frame; The wireless device also contains the waking-up device used for continuously sending waking data packet to wake up a slave device; the RF transceiver module of the slave device in the wireless device converts frequency to wake frequency, then go dormant, when it wakes, if it receives waking data packet, it converts to operating frequency and broadcasts the news that the slave device is already awake, when the master device receives the news, it sends data frame to the slave device; the slave device receives the data frame from the master device and executes instruction.
