Definitions

  • the present disclosure relates to the field of passenger information management in rail vehicles, and in particular to a passenger information system and a method for controlling the passenger information system.
  • a passenger information system is configured to issue a vehicle control instruction and display passenger information to passengers.
  • the passenger information system is significant in a rail vehicle including multiple carriages. Therefore, it is crucial to improve redundancy of the passenger information system, so as to avoid that the instruction and the information fail to be transmitted in time, and ensure normal communication of all links in the passenger information system.
  • the redundancy of the passenger information system is implemented by communication between two cab control hosts. That is, two cab control hosts respectively arranged in a front cab and a rear cab of the vehicle and carriage control hosts arranged in carriages of the vehicle are connected in series to each other. In a case that one of the two cab control hosts fails, the other of the two cab control hosts controls these carriage control hosts. However, in a case that one of these carriages control host fails, the passenger information system cannot function normally.
  • a passenger information system and a method for controlling a passenger information system are provided according to the present disclosure, to improve the redundancy of the passenger information system and ensure normal communication of all links of the passenger information system.
  • the passenger information system includes a cab control host arranged in a cab, a carriage control host group arranged in a carriage and having a one-to-one correspondence with the carriage, and a train-level Ethernet bus.
  • the carriage control host group includes multiple carriage control hosts. Each of the multiple carriage control hosts is configured to control display of passenger information. Cab control hosts are connected to each other via the train-level Ethernet bus.
  • the cab control host is connected to each of the multiple carriage control hosts via the train-level Ethernet bus.
  • the cab control host is configured to: send the passenger information to the carriage control host; and switch from a failed carriage control host to a carriage control host operating normally in a carriage control host group including the failed carriage control host.
  • the number of the train-level Ethernet bus is more than one.
  • the cab control host includes a first switch for accessing a train control network, a second switch for accessing a train maintenance network and a third switch for accessing a carriage network.
  • the train control network, the train maintenance network and the carriage network all communicate based on the train-level Ethernet bus.
  • the passenger information system further includes a carriage Ethernet bus.
  • the multiple carriage control hosts in the carriage control host group are connected to each other via the carriage Ethernet bus.
  • the passenger information system further includes a display screen, a camera, a dynamic map, an alarm and a loudspeaker that are arranged in the carriage and connected to each of the multiple carriage control hosts.
  • the display screen is an LCD display screen.
  • each of the multiple carriage control hosts further includes a wireless communicator for communicating with a terminal device.
  • the wireless communicator is a Wi-Fi communicator.
  • a method for controlling a passenger information system includes: transmitting, by a cab control host, passenger information to a carriage control host; transmitting, by the carriage control host in receipt of the passenger information, feedback information to the cab control host, and displaying, by the carriage control host in receipt of the passenger information, the passenger information; and switching, by the cab control host when receiving no feedback information in a preset time period, from a failed carriage control host to a carriage control host operating normally in a carriage control host group including the failed carriage control host.
  • the carriage control host group has a one-to-one correspondence with the carriage, and includes multiple carriage control hosts.
  • the number of the train-level Ethernet bus is more than one.
  • multiple carriage control hosts are arranged in the carriage control host group of each carriage, to implement the redundancy of the carriage control host.

  • the carriage control host group 2 of each carriage includes the carriage control host 21 and the carriage control host 22.
  • the carriage control host 21 and the carriage control host 22 are respectively arranged at a front end and a rear end of the carriage.
  • one train-level Ethernet bus 3 fails, information is transmitted via the other train-level Ethernet bus 3.
  • a failed carriage control host in a carriage cannot result in a failed passenger information system.
  • multiple carriage control hosts are arranged in the carriage control host group of each carriage, to implement the redundancy of the carriage control host.
  • the cab control host switches from the failed carriage control host to the carriage control host operating normally in the carriage control host group including the failed carriage control host, to avoid a failed passenger information system caused by interruption of information transmission to the carriage control host, thereby improving the redundancy of the passenger information system, and ensuring the normal communication of all links of the passenger information system.

  • the train control network, the train maintenance network and the carriage network all communicate based on the train-level Ethernet bus.
  • a train is provided with the train control network, the train maintenance network and the carriage network that are used to transmit different information.
  • a node in each of the above networks is required to be provided with a switch since the networks are based on different protocols.
