and S4, sending the upgrade file to the vehicle-mounted equipment of each target train based on the communication controller so as to upgrade the vehicle-mounted equipment.
It should be noted that the execution subject of the method may be a computer device.
Optionally, on each train to be upgraded equipped with CBTC equipment, for example, a freight train, a communication connection between the Bootloader upper computer and each train to be upgraded is established, and each target train that can be upgraded is determined according to message data sent by each train to be upgraded and received by the Bootloader upper computer.
And finishing upgrading the vehicle-mounted equipment of each target train according to the communication connection between the starting loading upper computer and each target train.
The communication controller is an indispensable part in each target train ATP subsystem equipped with CBTC equipment, establishes communication connection between a Bootloader upper computer and the communication controller of each target train, and sends the upgrade file to the communication controller of each target train. The upgrade file may specifically include a kernel to be upgraded, data to be updated, and an NVRAM file.
And sending the upgrade file to the vehicle-mounted equipment of each target train based on the communication controller of each target train so as to finish remote upgrade of the vehicle-mounted equipment.
And under the condition that the upper loading computer is determined to be started to send an upgrading starting instruction (for example, a download button is clicked on the upper Bootloader computer), the upper Bootloader computer starts to send the upgrading file to the communication controllers of the target trains.
The Bootloader upper computer can be connected with the Bootloader upper computer and enters a bootstrap program when the Bootloader upper computer is just started, so that the Bootloader upper computer can integrate the remote power-on and power-off functions, when each target train needs to be upgraded, each target train is restarted remotely firstly, and the building of a link with each target train is completed after the target train is powered on; if no remote power-on and power-off function exists, the on-board personnel can restart each target train without other operations, and the on-board personnel can complete power-on and power-off operation by matching with ground personnel.
The remote upgrading method for the vehicle-mounted equipment provided by the invention can realize simultaneous remote upgrading of the vehicle-mounted equipment of a plurality of target trains in a network coverage area on the basis of fully considering the working intensity and the operation difficulty of field workers, thereby reducing the working intensity and the operation complexity of the field workers and lowering the requirements on the field workers.
Further, in an embodiment, the step S1 may specifically include:
s11, establishing communication connection between the starting loading upper computer and the ground LTE server according to the mapping relation between the IP address of the starting loading upper computer and the IP address of each train to be upgraded, which is stored in the preset mapping relation table;
and S12, establishing communication connection between the starting loading upper computer and each train to be upgraded through the ground LTE server and the vehicle-mounted LTE server of each train to be upgraded.
Optionally, the starting loading upper computer and each train to be upgraded are bound according to a mapping relation between an IP address of the starting loading upper computer and an IP address of each train to be upgraded, which is stored in a preset mapping relation table, then the Bootloader upper computer is connected to a network management center through a connection security data network and is accessed to a ground LTE server covering each train to be upgraded, and the Bootloader upper computer can be remotely connected with each train to be upgraded through a communication relation configured in advance, wherein the network connection mode is as shown in fig. 2. The Bootloader upper computer is connected with the ground LTE server through a network cable, the ground LTE server is communicated with the vehicle-mounted LTE server through a wireless local area network, and therefore after each target train which can be upgraded is determined according to message data sent by each train to be upgraded and received by starting the loading upper computer, the Bootloader upper computer can send an upgrade file containing an inner core to be upgraded, data to be updated and an NVRAM file to a communication controller of each target train, and the communication controller sends the upgrade file to vehicle-mounted equipment through an internal network such as a powerlink network deployed on each target train, so that remote upgrade of each target train is achieved.
It should be noted that each target train that needs to be remotely upgraded must stop within the coverage of the ground LTE server, the target train is kept in a powered-on state, the upgrade file is in a downloaded state, and the work point for updating the upgrade file for each target train should be arranged at the skylight point.
When the vehicles are actually updated, the stability of each target train must be guaranteed, and the main line operation is not influenced. The upgrading of each target train strictly meets the safe operation requirement, and the vehicle-mounted equipment cannot be upgraded at will.
The LTE network is an important carrier for realizing remote upgrade of the vehicle-mounted device, and theoretically, the time for updating all files (kernel to be upgraded, NVRAM file, and data to be updated) of one vehicle is about several minutes. Any vehicle in the whole line range in the skylight point can be updated by the remote control program of ground personnel as long as the vehicle is stopped stably and the normal operation of other vehicles is not influenced, so that the technical requirements on the personnel on the vehicle are reduced.
According to the remote upgrading method for the vehicle-mounted equipment, provided by the invention, an operator does not need to get on the vehicle, and communication connection between the starting loading upper computer and each train to be upgraded is established according to each train to be upgraded bound by the starting loading upper computer in the coverage range of the ground LTE server, so that the remote upgrading of the vehicle is realized, the manpower is greatly liberated, and the train upgrading time is saved.
Further, in an embodiment, the step S2 may specifically include:
s21, analyzing message data sent by each train to be upgraded to the starting loading upper computer to obtain the position information of each train to be upgraded and the IP address of each train to be upgraded;
and S22, determining each target train located at the preset skylight point according to the position information of each train to be upgraded and the IP address of each train to be upgraded.
Optionally, an interface between a communication controller of the train to be upgraded and an LTE network (including a ground LTE server and a vehicle-mounted LTE server) adopts a user datagram protocol UDP as a communication protocol of a transmission layer, and after each train to be upgraded sends message data to the start loading upper computer through the corresponding communication controller, the start loading upper computer analyzes the received message data sent by each train to be upgraded, and obtains position information and an IP address of each train to be upgraded from the analyzed message data.
And determining the train to be upgraded positioned at the preset skylight point according to the position information of each train to be upgraded, and determining each target train according to the IP address of the train to be upgraded positioned at the preset skylight point.
Therefore, after the loading upper computer is started and the IP addresses of the target trains are bound, communication connection can be established with the target trains through the loading upper computer, and remote upgrading of the vehicle-mounted equipment of the target trains is completed.
The remote upgrading method for the vehicle-mounted equipment enables an operator to be connected with the vehicle-mounted equipment on the ground without getting on the train, meanwhile, one vehicle does not need to correspond to one person, but one person can correspond to a plurality of vehicles, and meanwhile, the plurality of vehicles are upgraded, so that manpower is greatly liberated, and the train upgrading efficiency is improved.
Further, in an embodiment, the step S4 may specifically include:
s41, establishing communication connection between the communication controller and a target board card corresponding to the vehicle-mounted equipment based on an intranet deployed on each target train;
s42, sending the upgrade file to a target board card based on the communication controller so as to upgrade the vehicle-mounted equipment;
wherein, a starting loading lower computer is arranged in the target board card;
the starting loading lower computer is used for matching with the starting loading upper computer.
Optionally, referring to fig. 2, the Bootloader upper computer accesses the ground LTE server, and establishes a remote connection with each target train through the ground LTE server and the vehicle-mounted LTE server of each target train. The ground LTE interface server and the vehicle-mounted LTE server are communicated through a wireless local area network, so that the Bootloader upper computer can send the upgrade file to the vehicle-mounted communication controller, the communication controller is connected with corresponding target board cards (such as a signal board card, an input board card and an output board card) of the vehicle-mounted equipment through internal networks such as powerlink networks deployed on target trains, the upgrade file is sent to the target board cards through the powerlink networks through the communication controller, and the remote upgrade function of the vehicle-mounted equipment is achieved.
It should be noted that a Bootloader lower computer is deployed in the target board card.
The lower computer of the Bootloader is a section of bootstrap program which is a first section of code running when the upper computer of the Bootloader is just electrified. Therefore, the premise of remote upgrading is that Bootloader lower computer codes are arranged in each target board card to be upgraded in the ATP subsystem of each target train, and the Bootloader lower computers are matched with the Bootloader upper computers for use.
And after the updating of the upgrading file is finished, remotely restarting the target train, and running the updated upgrading file to finish one-time upgrading of the target train. And no matter where the target train is, the remote upgrading can be realized as long as the target train can be connected to the communication controller of the target train through the LTE network.
The remote upgrading method for the vehicle-mounted equipment can reduce the labor cost and time cost for train upgrading and reduce the work of operators.
Further, in an embodiment, the step S42 may specifically include:
s421, determining the ID of the board card to be upgraded according to address information extracted by starting the loading upper computer from the received upgrade verification request sent by each target train;
s422, determining a target board card according to the ID of the board card to be upgraded;
s423, based on the communication controller, sending the upgrade file corresponding to the version information to the target board card to upgrade the vehicle-mounted equipment;
the upgrading verification request carries the ID of the board card to be upgraded and the version information corresponding to the upgrading file.
Optionally, after determining each target train to be upgraded based on the above process, each target train sends an upgrade verification request carrying an ID of a board to be upgraded and version information corresponding to the upgrade file to the Bootloader upper computer through the communication controller, the Bootloader upper computer is started to extract address information from the received upgrade verification request sent by each target train, the address information is used for determining the ID of the board to be upgraded, and the target board to be upgraded is determined according to the obtained ID of the board to be upgraded.
And then, based on the communication controller, sending the upgrade file corresponding to the version information to the target board card so as to complete the upgrade of the vehicle-mounted equipment. According to the remote upgrading method for the vehicle-mounted equipment, the target board card for upgrading is determined based on the upgrading verification request received by the starting and loading upper computer, remote upgrading of the vehicle-mounted equipment of each target train is achieved, and meanwhile driving safety caused by random upgrading of the vehicle-mounted equipment is avoided.
Further, in an embodiment, step S42 may further specifically include:
s424, judging whether the target board card successfully finishes downloading the upgrade file according to the upgrade finishing condition of the target board card in the target train displayed on the starting and loading upper computer;
s425, if the target board cards in the target trains finish downloading the upgrade files, disconnecting the communication connection between the communication controllers in the target trains and the target board cards;
and S426, if the board card which fails to download the upgrade file exists, sending the upgrade file to the board card which fails to download again according to a Powerlink intranet which is deployed on a target train corresponding to the board card which fails to download.
Optionally, the Bootloader upper computer establishes communication connection of each target train through a network connection method as shown in fig. 2, selects the vehicle-mounted device to be upgraded corresponding to each target train and performs remote communication connection, specifically:
the Bootloader upper computer is connected with a ground LTE server in a wired connection (such as a network cable) mode, the ground LTE server and a vehicle-mounted LTE server are connected in a communication mode through accessing the same wireless local area network, the vehicle-mounted LTE server and a communication controller are connected through network cables arranged on various target trains, and finally the communication controller and target board cards (such as signal board cards, input board cards and output board cards) corresponding to vehicle-mounted equipment are connected through a vehicle intranet such as a Powerlink network.
And under the condition that the download button is clicked on the upper computer of the Bootloader, starting to send the upgrade files to the communication controllers of the target trains through the upper computer of the Bootloader. The communication controller is connected with a target board card corresponding to the vehicle-mounted equipment in a mode of being deployed in an intranet of each target train, and sends the upgrade file to the corresponding target board card.
The method comprises the steps that the upgrading completion condition of a target board card in a target train is displayed in real time on a Bootloader upper computer, including the downloading progress and downloading speed of an upgrading file, whether the target board card finishes downloading the upgrading file or not is judged, and if the target board card in each target train finishes downloading the upgrading file, the communication connection between a communication controller in each target train and the target board card is disconnected;
and if the board card fails to download the upgrade file, sending the upgrade file to the board card failed to download again according to a Powerlink intranet deployed on a target train corresponding to the board card failed to download.
And after the target board card in the target train finishes updating the upgrade file, remotely restarting the communication controller of each target train and operating the updated upgrade file.
