Abstract: A method, system and device for controlling a door of a railway vehicle are provided. The method comprises: a door control instruction sent by a transponder is received when a railway vehicle draws into the station, wherein the door control instruction is used for determining a door of the railway vehicle at a platform side; and the railway vehicle is controlled to open the door of the railway vehicle at the platform side according to the door control instruction, thereby solving the technical problem that the door of a railway vehicle at the non-platform side may be opened by mistake by a driver due to human factors because the door of the railway vehicle at the platform side is manually opened when the railway vehicle stops.

Abstract: Disclosed is an alarming and unlocking device. The alarming and unlocking device is installed in a passenger carriage and includes a control switch (10), a communication device, and a locking device, wherein the control switch (10) is provided with an alarming position (11) and an unlocking position (12); the control switch (10) is in signal connection with the communication device; when the control switch (10) is located at the alarming position (11), the communication device is started to receive and send a voice signal; the locking device is installed on a door so as to control the door to lock or unlock; the control switch (10) is in signal connection with the locking device; and when the control switch (10) is located at the unlocking position (12), the locking device performs an unlocking operation. According to the alarming and unlocking device, the problem that a structure for an alarming and unlocking device on a vehicle is relatively complex in the conventional art is solved.

Abstract: A method, device and system for controlling a fuel cell and a rail vehicle are provided. The method includes: an operating power of a target object is detected, wherein the target object is powered by at least two fuel cells (S102); when it is detected that the operating power of the target object is lower than a predetermined power, at least one fuel cell is turned off or a cell component in any one or more fuel cells is turned off according to a gas conversion range corresponding to the fuel cell (S104), wherein the gas conversion range is an output power range value, of the fuel cell, corresponding to a preset range value of a hydrogen conversion rate of the fuel cell.

Abstract: A method and a device for transmitting signals among compartments of a train are provided. The method comprises: receiving a first signal transmitted via a jumper cable, and extracting first data carried in the first signal; receiving a second signal transmitted wirelessly corresponding to the first signal, and extracting second data carried in the second signal; and determining whether the first data is identical with the second data, and outputting the first signal in a case that it is determined that the first data is identical with the second data, or outputting the second signal in a case that it is determined that the first data is not identical with the second data. The method and the device improve the reliability of transmission of signals among compartments of a train.
