[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Combine the following Figures 1 to 3 The signal system of the coupled trains of the present invention is described.

[0044] It should be noted that the coupled train is an urban rail transit train, including but not limited to urban rail or subway.

[0045] The coupled train includes: a first marshaling train and a second marshaling train.

[0046] The first train set and the second train set are respectively rail trains with a front, a carriage and a rear. For example, the first train set and the second train set can be 4-carriage or 6-carriage trains respectively.

[0047] The first train set and the second train set can be coupled to form the same coupled train, wherein the first train set and the second train set are coupled trains to each other.

[0048] like Figure 1 As shown, the signal system of the coupled train includes: vehicle gateway equipment, signal network equipment, signal control equipment and gateway server.

[0049] In this embodiment, the gateway server may be arranged on the coupled train, or may be a server communicatively connected to the coupled train.

[0050] The gateway server allocates a fixed IP to each device based on the device type on the coupled train, where the device type includes signal network devices and other network devices.

[0051] Different device types have different corresponding IP addresses.

[0052] It should be noted that the IP of each signal network device is fixed, that is, when the rail train is in a single formation or coupled, the IP of its signal network device remains consistent.

[0053] Among them, signal control equipment includes but is not limited to: speed sensors, radars, human-computer interaction units, and automatic train control systems ATC, etc.

[0054] Both the first train set and the second train set are provided with a vehicle gateway device and a signal network device, and the signal network device is electrically connected to the vehicle gateway device.

[0055] In some embodiments, the electrical connection may be in the form of a wired electrical connection via a cable.

[0056] The vehicle gateway device is a train control and management system module. TCMS can connect various control devices of coupled trains through the network for unified control and information sharing. Each vehicle gateway device communicates with each other through the coupled train bus.

[0057] The signaling network device is a transmission control protocol module designed to adapt to the layered protocol hierarchy supporting multiple network applications and can provide reliable end-to-end byte flow over an unreliable internetwork.

[0058] The first train set and the second train set are both equipped with signal control equipment. The signal control equipment on each train set is electrically connected to the vehicle gateway equipment on the train set through the signal network equipment, and the signal network equipment on the first train set and the signal network equipment on the second train set are electrically connected to each other.

[0059] It should be noted that, in this embodiment, the signal control device on the first train set and the signal control device on the second train set are communicatively connected with the signal gateway device via the vehicle network device.

[0060] The signal system of coupled trains provided in an embodiment of the present invention realizes network addressing between coupled trains by connecting the signal control device to the TCMS network, distinguishing the signal network device from other devices by using IP, and transmitting signals between the coupled trains by TCP protocol. Signal transmission between coupled trains can be carried out without specially customized electric couplers, with low construction cost and low communication delay.

[0061] like Figure 2 As shown, in some embodiments, the signal control device includes a first signal control device and a second signal control device, and the signal network device includes a first signal network device 110 and a second signal network device 111 .

[0062] The first signal control device and the first signal network device 110 are respectively arranged at the head ends of the first train set and the second train set, and the first signal control device is electrically connected to the vehicle gateway device through the first signal network device 110 .

[0063] The second signal control device and the second signal network device 111 are respectively arranged at the rear ends of the first train set and the second train set, and the second signal control device is electrically connected to the vehicle gateway device through the second signal network device 111 .

[0064] The second signal network device on the first train set is electrically connected to the first signal network device on the second train set.

[0065] In this embodiment, each train set is provided with a first signal control device, a second signal control device, a first signal network device 110, a second signal network device 111 and a vehicle gateway device.

[0066] The first signal network device and the second signal network device are electrically connected to the vehicle gateway device respectively, and receive the train-level network segment after coupling.

[0067] Among them, the network segment is a physical segment in the network where devices using the same physical layer can communicate directly.

[0068] When the first train set and the second train set are coupled to form the same coupled train, the first train set and the second train set are coupled trains to each other, and the first train set and the second train set can communicate within the train-level network segment.

[0069] For example, if the network segment of the first train set is the AB interval, and the network segment of the second train set is the CD interval, then the second signal network device installed on the first train set is informed that the network segment corresponding to the second train set coupled to it is the CD interval; and the first signal network device installed on the second train set is informed that the network segment corresponding to the first train set coupled to it is the AB interval.

[0070] In the actual implementation process, when the second signal network device 111 electrically connected to the second signal control device on the first train set receives a signal with a network segment of CD, it confirms that the signal is sent by the second train set and performs signal transmission.

[0071] When the first signal network device 110 electrically connected to the first signal control device on the second train set receives the signal with the network segment AB, it confirms that the signal is the signal sent by the first train set and performs signal transmission.

[0072] In some embodiments, the gateway server is electrically connected to the first signal network device and the second signal network device respectively, and the gateway server is used to allocate IP1 to the first signal network device and allocate IP2 to the second signal network device;

[0073] The IP1 corresponding to the first train set and the second train set are the same, and the IP2 corresponding to the first train set and the second train set are the same.

[0074] During the actual execution process, the gateway server assigns the same fixed IP1 to the first signal network device corresponding to the first train set and the first signal network device corresponding to the second train set, and assigns the same fixed IP2 to the second signal network device corresponding to the first train set and the second signal network device corresponding to the second train set.

[0075] The first signal network device 110 on the first train set maps IP1 corresponding to the first signal control device to IP11, and the second signal network device 111 maps IP2 corresponding to the second signal control device to IP12.

[0076] Similarly, the first signal network device 110 on the second train set maps IP1 corresponding to the first signal control device to IP21, and the second signal network device 111 maps IP2 corresponding to the second signal control device to IP22.

[0077] Among them, IP11, IP12, IP21 and IP22 are different.

[0078] According to the signal system of coupled trains provided in an embodiment of the present invention, two signal network devices with different IP addresses are arranged on each marshaled train, and the devices are connected to the TCMS network at the same time, and the signal transmission between the marshaled coupled trains is performed through the TCP protocol, thereby realizing signal transmission between the coupled trains without the need for specially customized electric couplers, with low construction cost and low communication delay.

[0079] In some embodiments, the signal system of the coupled train further includes: a router.

[0080] In this embodiment, the router is electrically connected to the signal control device to provide a routing path across workshops for coupled trains, thereby providing a dedicated route for the signal control device to communicate across workshops.

[0081] In some embodiments, the signal system of the coupled train further includes: a gateway.

[0082] In this embodiment, the gateway is electrically connected to the signal control device, thereby achieving communication between the first coupled train and the second coupled train.

[0083] According to the signal system of coupled trains provided by the embodiment of the present invention, routers and gateways are provided, thereby enabling communication of signal control devices across workshops.

[0084] The implementation of the system is described below through specific embodiments.

[0085] In some embodiments, the signal network device is used to set the TOS field in the IP message to a target value, and the target value is used to identify the signal network device;

[0086] The vehicle gateway device is used to parse the TOS field in the IP message and generate a parsed value; and when the parsed value is the target value, network transmission is given priority.

[0087] In this embodiment, if Figure 3 As shown, the TOS field is a field in the IP message.

[0088] It is understandable that various types of equipment are provided on the coupled train, and the TOS field is set to different values ​​to distinguish the types of the equipment.

[0089] The target value is the numerical value corresponding to the signal network device, and the target value can be customized by the user.

[0090] It should be noted that the target values ​​corresponding to the signal network devices in each train set are the same, that is, the values ​​of the TOS fields in the IP messages corresponding to each signal network device are consistent.

[0091] After the signal network device sets the TOS field in the IP message to the target value to generate a target IP message, the target IP message is sent to the vehicle gateway device.

[0092] The vehicle gateway device receives the target IP message and parses the TOS field to obtain the parsed value.

[0093] It can be understood that, in the actual execution process, the vehicle gateway device receives IP messages sent by multiple types of devices, and parses the value of the TOS field in each IP message. When the parsed value is consistent with the target value, it determines that the IP message is the IP message corresponding to the signal network device, thereby giving priority to the network transmission of the signal data sent by the signal network device.

[0094] In some embodiments, the signal network device is used to map the IP and generate a mapped IP before network transmission.

[0095] like Figure 2 As shown, in this embodiment, the first signal network device 110 on the first train set maps IP1 of the first signal control device to generate mapped IP11; the second signal network device 111 maps IP2 of the second signal control device to generate mapped IP12.

[0096] Similarly, the first signal network device 110 on the second train set maps IP1 of the first signal control device to generate mapped IP21; the second signal network device 111 maps IP2 of the second signal control device to generate mapped IP22.

[0097] The first signal network device 110 installed on the first train assembly communicates with the second signal network device 111 via IP11 and IP12, the first signal network device 110 installed on the second train assembly communicates with the second signal network device 111 via IP21 and IP22, and the second signal network device 111 installed on the first train assembly communicates with the first signal network device 110 installed on the second train assembly via IP12 and IP21.

[0098] The signal control device is electrically connected to the vehicle network device, and the vehicle gateway device is electrically connected to the signal network device, thereby achieving electrical connection between the signal control device and the signal network device.

[0099] Based on the target IP message, the vehicle gateway device gives priority to network transmission if it is determined to be a signal network device.

[0100] During the actual transmission process, the first signal control device installed on the first marshaling train communicates with the second signal control device through IP11 and IP12, the first signal control device installed on the second marshaling train communicates with the second signal control device through IP21 and IP22, and the second signal control device installed on the first marshaling train communicates with the first signal control device installed on the second marshaling train through IP12 and IP21.

[0101] According to the signal system of coupled trains provided in an embodiment of the present invention, by connecting the signal control device to the TCMS network through the signal network device and using the TOS field in the IP field to identify the signal network device, the vehicle gateway device can identify the signal network device and give priority to transmitting the signal on the signal network device, so as to achieve high-priority transmission of signal data.

[0102] The following is a description of the coupled train communication method based on network fusion provided by the present invention. The coupled train communication method based on network fusion described below and the coupled train signal system described above can be referenced to each other.

[0103] In some embodiments, the coupled train communication method based on network fusion includes:

[0104] Send IP and train-level network segment after coupling;

[0105] Generate a target IP message based on the IP message, the target IP message is used to identify the signal network device;

[0106] Based on the target IP message, determine whether it is a signal network device;

[0107] If it is determined to be a signal network device, the IP will be mapped and network transmission will be prioritized within the train-level network segment.

[0108] In this embodiment, the IP is the IP corresponding to each device on the train set, and different types of devices correspond to different IPs.

[0109] Equipment can be divided into signal network equipment and other network equipment according to type.

[0110] Among them, signal network equipment includes but is not limited to: speed sensors, radars, human-computer interaction units, and automatic train control systems ATC, etc.

[0111] It should be noted that the IP of each signal network device is fixed, that is, when the rail train is in a single formation or coupled, the IP of its signal network device remains consistent.

[0112] A network segment is a physical segment in a network where devices on the same physical layer can communicate directly. For example, the network segment of the first train set is the physical segment AB, and the network segment of the second train set is the physical segment CD.

[0113] After receiving the IP of the signal network device, a target IP message is generated based on the IP message. The target IP message is used to identify the signal network device.

[0114] The target IP message is the IP message corresponding to the signal network device.

[0115] Based on the target IP message, determine whether it is a signal network device.

[0116] In this step, the received IP messages corresponding to the multiple devices are parsed, and when the parsed IP message obtained is consistent with the target IP message, it is determined that the IP message is the IP message corresponding to the signal network device.

[0117] If it is determined to be a signal network device, the IP will be mapped and network transmission will be prioritized within the train-level network segment.

[0118] Among them, the IP is mapped to generate a mapped IP, and the mapped IPs are different.

[0119] After the mapping is completed, based on the mapped IP, the signal data sent by the signal network device is preferentially transmitted over the network.

[0120] In some embodiments, generating a target IP packet based on the IP packet includes:

[0121] The TOS field in the IP message is set to a target value to generate a target IP message, and the target value is used to identify the signal network device.

[0122] In this step, the target value is a numerical value corresponding to the signal network device, and the target value can be customized based on the user.

[0123] It should be noted that the target values ​​corresponding to the signal network devices in each train set are the same, that is, the values ​​of the TOS fields in the IP messages corresponding to each signal network device are consistent.

[0124] Based on the target IP message, determine whether it is a signal network device, including:

[0125] Parse the TOS field in the target IP message and generate a parsed value;

[0126] When the analyzed value is the target value, it is determined to be a signal network device.

[0127] In this step, the TOS fields in the received IP messages corresponding to the multiple devices are parsed, and when the obtained parsed value is consistent with the target value, it is determined that the IP message is the IP message corresponding to the signal network device.

[0128] After determining that the IP message is the IP message corresponding to the signal network device, the signal data sent by the signal network device is preferentially transmitted over the network to achieve high priority transmission of the signal data.

[0129] According to the network convergence-based coupled train communication method provided by an embodiment of the present invention, two signal network devices with different IPs are set on each marshaled train, and the TCMS network is connected at the same time, and the signal transmission between the marshaled coupled trains is performed through the TCP protocol, thereby realizing the transmission of signals between the coupled trains without the need for specially customized electric couplers, with low construction cost and low communication delay; in addition, the signal network device is identified by the TOS field in the IP field, so that the vehicle gateway device can identify the signal network device and preferentially transmit the signal on the signal network device, so as to realize high-priority transmission of signal data.

[0130] The following is a description of the coupled train communication device based on network fusion provided by the present invention. The coupled train communication device based on network fusion described below and the coupled train communication method based on network fusion described above can be referenced to each other.

[0131] The coupled train communication device based on network fusion includes:

[0132] The first sending module is used to send IP and the train-level network segment after coupling;

[0133] A first processing module, used to generate a target IP message based on the IP message, where the target IP message is used to identify the signal network device;

[0134] A second processing module, used to determine the target IP message as a signal network device;

[0135] The third processing module is used to map the IP when it is determined to be a signal network device, and give priority to network transmission within the train-level network segment.

[0136] In some embodiments, the first processing module is further used to: set the TOS field in the IP message to a target value to generate a target IP message, the target value being used to identify the signal network device;

[0137] The second processing module is further used for:

[0138] Parse the TOS field in the target IP message and generate a parsed value;

[0139] When the analyzed value is the target value, it is determined to be a signal network device.
