On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
Fig. 1 is a schematic flowchart of a method for configuring a reconnection gateway according to an embodiment of the present invention, where the method for configuring a reconnection gateway includes the following steps:
s101, the reconnection gateway receives a hard wire signal sent by a corresponding dialer.
In this embodiment, in order to enable reconnection of a plurality of train cars, a dialer and a reconnection gateway are preset for each train car. After the train cars are reconnected, the state of each dial switch in the dialer is set by the train driver or the train crew. Different states issue different hard-wired signals. When the dial switch is in an on state, a '1' is sent out, and when the dial switch is in an off state, a '0' is sent out. After the state setting of each dial switch in the dial-up device is finished, a hard-line signal consisting of 0 and 1 can be sent out after the dial-up device is powered on. In order to realize communication among a plurality of train cars, the reconnection gateway arranged on the train car can receive the hard wire signal sent by the corresponding code dialing device, and the address of the reconnection gateway is configured through the hard wire signal.
Specifically, the train selects to communicate based on a Controller Area Network (CAN) bus. The reconnection gateway CAN convert the hard wire signal into a network signal conforming to the CAN bus standard, and the network signal is carried in a message and sent to the main controller.
The dialer may encode a hard-wired signal, for example, a three-bit dialer, which includes 3 dial switches. The addresses of 8 reconnection gateways can be shown as shown in table 1, by analogy, four-bit dialers can show the addresses of 16 reconnection gateways, five bits can show the address of a 32-bit reconnection gateway, and the like, and the selection of the dialer is determined according to the number of train cars needing reconnection. Where address 0 is not used because the default state of unpowered is 0, avoiding interference confusion. Table 1 herein is merely an example and is not intended as a limitation of the present invention.

S102, the reconnection gateway sends a configuration message carrying a hard wire signal to a main controller on the train so that the main controller can identify the hard wire signal from the received configuration message and configure the address of the reconnection gateway by using the hard wire signal.
Generally, a controller is arranged in each train carriage on the train, and one of the controllers can be used as a main controller. After acquiring the hard-wire signal, the reconnection gateway can carry the hard-wire information in a configuration message and send the configuration message to the main controller. The hard-wired signal is identified by the master controller from the received configuration message. All the reconnection gateways on the train carriages send configuration messages to the main controller, in order to avoid conflict of gateway addresses of the reconnection gateways, the main controller needs to judge whether all the hard line signals conflict or not after receiving all the configuration messages, and when judging that no conflict exists, the hard line signals are used for configuring the addresses of the reconnection gateways. And when the conflict is judged to exist, the feedback is given to the staff of the train, so that the staff of the train reconfigures the dialer to avoid the conflict.
Further, after the reconnection gateway sends a configuration message carrying a hard-wired signal to the main controller on the train, so that the main controller identifies the hard-wired signal from the received configuration message, and configures an address of the reconnection gateway by using the hard-wired signal, the method further includes:
the reconnection gateway can receive the message sent by the carriage intranet and forwards the message sent by the carriage intranet to the main controller, and the main controller can process the received message. Before forwarding the message to the main controller, in order to distinguish the message from messages sent by other train carriages, the reconnection gateway needs to add the gateway address of the reconnection gateway into the message sent by the carriage intranet, and then forwards the message to the backbone network so as to send the message to the main controller for processing.
Furthermore, the reconnection gateway can also receive the message sent by the main controller from the backbone network and forward the message sent by the main controller to the carriage intranet where the reconnection gateway is located. In order to send the message to the reconnection gateway, the master controller needs to add the gateway address of the reconnection gateway to the message, so that the message can be sent to the reconnection gateway according to the gateway address. After receiving the message sent from the backbone network, the reconnection gateway needs to forward the message to a controller on the train carriage where the reconnection gateway is located for processing. Because the network formed between the controller on the train carriage and the reconnection gateway is the internal network of the train carriage, when the reconnection gateway forwards the message to the controller on the train carriage, the gateway address does not need to be added on the message. In this embodiment, when forwarding a packet, the reconnection gateway needs to forward the packet according to a preset packet forwarding rule.
In the configuration method for the reconnection gateway provided by this embodiment, the reconnection gateway receives a hard-line signal sent by a corresponding dialer, and sends a configuration message carrying the hard-line signal to a main controller on the train, so that the main controller identifies the hard-line signal from the received configuration message, and configures an address of the reconnection gateway by using the hard-line signal. In the embodiment, the hard-line signal is generated by the code dialing device to configure the address of the reconnection gateway, namely, the address of the reconnection gateway is configured by the hard line, so that the method is safer and more reliable compared with network configuration, is not easy to make mistakes, and does not occupy network load rate. And the method is relatively simple in technology, is easier to realize, and is particularly suitable for newly developed test lines. And the configuration is carried out through hard wire signals, so that the network identification is suitable for all network identifications, and the compatibility is strong. The states of the dial switches of the dialers can be adjusted at any time, so that the sequence of the carriages can be flexibly configured. And it is easier to increase the dial switch in the dial-up device, so that the number of the train carriages reconnected on the train is not limited.
Fig. 2 is a schematic flowchart of another method for configuring a reconnection gateway according to an embodiment of the present invention. The method for configuring the reconnection gateway comprises the following steps:
s201, the main controller receives a configuration message sent by the reconnection gateway.
Wherein, the configuration message carries the hard-line signal sent by the dialer corresponding to the reconnection gateway.
In this embodiment, a train may have a master controller, and the master controller may receive configuration messages sent by reconnection gateways in all train cars from the backbone network. The configuration message carries a hard-line signal sent by a dialer corresponding to the reconnection gateway. For the descriptions of the dialer and the hard-wired signal, reference may be made to the descriptions in the foregoing embodiments and table 1, and further description is omitted here.
In this embodiment, before the main controller receives the configuration message sent by the reconnection gateway, the main controller needs to be determined. Specifically, one is selected from the controllers of all the train cars as a master controller. Specifically, the train driver may insert a key into the key fob of one of the train cars, which may trigger an indicating hardwired signal that instructs the controller in the selected train car to be set as the master controller. Typically, the controller in the first train car is selected as the master controller.
In the embodiment, one controller is arranged for each train carriage to realize redundancy, and when the main controller fails, the controller can be flexibly switched to other controllers to continue controlling the train. And because the controller in every train carriage can realize the same effect for arbitrary train carriage all can regard as main control unit in the train, the order of adjustment train carriage that can be more nimble.
Further, in this embodiment, after the master controller is determined, the other controllers serve as slave controllers. All the input and output modules (RIOM) corresponding to the slave controllers are in a suppression state, the master and slave controllers can receive messages from the backbone network, but the slave controllers cannot output signals because the input and output modules are in suppression devices.
S202, the main controller identifies the hard-line signal from the configuration message.
In this embodiment, the train may communicate based on the CAN bus. After the configuration message is received, the configuration message is analyzed according to the CAN bus standard, and the hard-line signal CAN be identified from the configuration message.
And S203, the main controller configures the address of the reconnection gateway by using the hard wire signal.
After obtaining the hard-wired signal, the address of the reconnection gateway may be configured by using the hard-wired signal. Because all the reconnection gateways on the train carriages send configuration messages to the main controller, in order to avoid conflict of gateway addresses of the reconnection gateways, the main controller needs to judge whether all the hard line signals conflict or not after receiving all the configuration messages, and when judging that no conflict exists, the hard line signals are used for configuring the addresses of the reconnection gateways. And when the conflict is judged to exist, the feedback is given to the staff of the train, so that the staff of the train reconfigures the dialer to avoid the conflict.
Further, when the main controller determines that there is no conflict in the hard-wire signals sent by all the reconnection gateways, after configuring the addresses of the reconnection gateways with the hard-wire signals, the method further includes:
the main controller forwards the message to the train carriage intranet where the reconnection gateway is located through the reconnection gateway, and specifically, in order to send the message to the reconnection gateway, the main controller needs to add a gateway address of the reconnection gateway to the message, so that the message can be sent to the reconnection gateway according to the gateway address. The reconnection gateway can also receive a message sent by the main controller from the backbone network and forward the message sent by the main controller to the carriage intranet where the reconnection gateway is located. After receiving the message sent from the backbone network, the reconnection gateway needs to forward the message to a controller on the train carriage where the reconnection gateway is located for processing. Because the network formed between the controller on the train carriage and the reconnection gateway is the internal network of the train carriage, when the reconnection gateway forwards the message to the controller on the train carriage, the gateway address does not need to be added on the message. In this embodiment, when forwarding a packet, the reconnection gateway needs to forward the packet according to a preset packet forwarding rule.
Further, the main controller receives a message forwarded by the reconnection gateway and sent by an intranet of the train carriage where the reconnection gateway is located. Specifically, the reconnection gateway may receive a message sent from the internal network of the car where the reconnection gateway is located, and before forwarding the message to the main controller, in order to distinguish the message from messages sent from other train cars, the reconnection gateway needs to add a gateway address of the reconnection gateway to the message sent from the internal network of the car where the reconnection gateway is located, and then forward the message to the backbone network so as to send the message to the main controller for processing.
In the configuration method for the reconnection gateway provided by this embodiment, the main controller on the train receives the configuration packet carrying the hard-line signal, identifies the hard-line signal from the received configuration packet, and configures the address of the reconnection gateway by using the hard-line signal. In the embodiment, the address of the reconnection gateway is configured by generating the hard-line signal through the code dialing device, namely, the address of the reconnection gateway is configured through the hard line, so that the method is safer and more reliable compared with network configuration, is not easy to make mistakes, and does not occupy network load rate. And the method is relatively simple in technology, is easier to realize, and is particularly suitable for newly developed test lines. And the configuration is carried out through hard wire signals, so that the network identification is suitable for all network identifications, and the compatibility is strong. The states of the dial switches of the dialers can be adjusted at any time, so that the sequence of the carriages can be flexibly configured. And it is easier to increase the dial switch in the dial-up device, so that the number of the train carriages reconnected on the train is not limited.
Fig. 3 is a schematic flowchart of another method for configuring a reconnection gateway according to an embodiment of the present invention. The method for configuring the reconnection gateway comprises the following steps:
and S301, configuring a dialer.
In this embodiment, a dialer and a reconnection gateway are preset for each train car. After the train cars are reconnected, the state of each dial switch in the dialer is set by the train driver or the train crew. Different states issue different hard-wired signals. When the dial switch is in an on state, a '1' is sent out, and when the dial switch is in an off state, a '0' is sent out. The driver of the train can manually configure the dialer, the dialer of the first train carriage is set to 001, and the first train carriage and the last train carriage are sequentially arranged backwards. The number of dial switches in the dial-up unit is set according to the number of the train carriages required to be reconnected. For example, when it is desired to reconnect 7 train cars, 3-digit dials are required, i.e., 3 dials per dial are required. If 4-digit dials are required when it is desired to reconnect 10 train cars, i.e., 3 dials per dial are required.
And S302, inserting the key into the key end of the train carriage selected as the master control carriage.
Each train carriage is provided with a controller, each controller is provided with a corresponding driver control platform, and the driver control platform is provided with a related key end or a key switch and the like. After the train driver selects the train carriage as the master carriage, the train driver can insert a key into the key end of the train carriage to trigger the generation of an indication hard line signal, and after the selected train carriage, the controller on the train carriage becomes the master controller of the train. Accordingly, the controllers on the other train cars will become slave controllers. All the input and output modules (RIOM) corresponding to the slave controllers are in a suppression state, the master and slave controllers can receive messages from the backbone network, but the slave controllers cannot output signals because the input and output modules are in suppression devices.
And S303, powering on the reconnection gateway and the controller.
And S304, the reconnection gateway receives the hard wire signal sent by the corresponding dialer.

The reconnection gateway converts the hard wire signal into a network signal conforming to the CAN bus standard, and the reconnection gateway carries the network signal in a message and sends the message to the main controller.
S306, the main controller identifies the hard-line signal from the received configuration message.
In this embodiment, the train may communicate based on the CAN bus. After the configuration message is received, the configuration message is analyzed according to the CAN bus standard, and the hard-line signal CAN be identified from the configuration message.
And S307, the main controller configures the address of the reconnection gateway by using the hard wire signal.
After obtaining the hard-wired signal, the address of the reconnection gateway may be configured by using the hard-wired signal. Because all the reconnection gateways on the train carriages send configuration messages to the main controller, in order to avoid conflict of gateway addresses of the reconnection gateways, the main controller needs to judge whether all the hard line signals conflict or not after receiving all the configuration messages, and when judging that no conflict exists, the hard line signals are used for configuring the addresses of the reconnection gateways. And when the conflict is judged to exist, the feedback is given to the staff of the train, so that the staff of the train reconfigures the dialer to avoid the conflict.
And S308, forwarding the message by the reconnection gateway according to a preset forwarding rule.
Specifically, the reconnection gateway receives a message sent by the carriage intranet, and forwards the message sent by the carriage intranet to the main controller. Further, the reconnection gateway receives the message sent by the main controller from the backbone network, and forwards the message sent by the main controller to the carriage intranet where the reconnection gateway is located.
The process of forwarding the packet by the reconnection gateway according to the preset forwarding rule may refer to the record of the related content in the above embodiment, and is not described herein again. In this embodiment, when forwarding a packet, the reconnection gateway needs to forward the packet according to a preset packet forwarding rule.
In the embodiment, the address of the reconnection gateway is configured by generating the hard-line signal through the code dialing device, namely, the address of the reconnection gateway is configured through the hard line, so that the method is safer and more reliable compared with network configuration, is not easy to make mistakes, and does not occupy network load rate. And the method is relatively simple in technology, is easier to realize, and is particularly suitable for newly developed test lines. And the configuration is carried out through hard wire signals, so that the network identification is suitable for all network identifications, and the compatibility is strong. The states of the dial switches of the dialers can be adjusted at any time, so that the sequence of the carriages can be flexibly configured. And it is easier to increase the dial switch in the dial-up device, so that the number of the train carriages reconnected on the train is not limited.
