It should be apparent that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a reconnection control system for a train according to the present invention, where the reconnection control system for a train may include: a plurality of reconnection control devices, and all include among each reconnection control device:
a processor 10;

the MVB communication module 30 is used for performing data interaction with vehicle-mounted equipment in the reconnection train unit under the control of the processor 10;
and the ethernet communication module 40 is configured to perform ethernet communication with the ethernet communication module 40 in the adjacent reconnection control apparatus under the control of the processor 10.
Specifically, in the solution of the present application, the wireless communication module 20, the mvb communication module 30, and the ethernet communication module 40 need to be communicatively connected to the processor 10, so as to implement multiple communication technologies into a whole, and therefore, the processor 10 of the present application should be selected as the high performance processor 10.
Specifically, the processor 10 of the present application may be an embedded technology-based processor 10, which can effectively combine multiple communication technologies and has the advantages of small size, low cost, low power consumption, and the like. And it is understood that since the wireless communication module 20, the mvb communication module 30 and the ethernet communication module 40 are all required to be connected to the processor 10 in communication, the processor 10 with rich external interfaces should be selected.
In one particular case, the processor 10 is an embedded processor 10, having a data processing speed of 1GHz, which provides the possibility of real-time processing of large data volumes.
In one embodiment of the present invention, the processor 10, the wireless communication module 20, the mvb communication module 30, and the ethernet communication module 40 in the same reconnection control device are integrated into a single board.
In this embodiment, the processor 10, the wireless communication module 20, the mvb communication module 30, and the ethernet communication module 40 in the same reconnection control device are all integrated in a single board, which effectively improves the integration level of the reconnection control device of the present application, and is beneficial to further reducing the volume.
The wireless communication module 20 of the present application is communicatively connected to the processor 10, and can perform wireless communication with the wireless communication module 20 in an adjacent reconnection control apparatus under the control of the processor 10. It can be understood that, for example, 4 reconnection control devices are arranged from the head to the tail, which are sequentially referred to as reconnection control devices a, B, C, and D, when the reconnection control device a at the head needs to perform wireless communication with the reconnection control device D at the tail, the reconnection control device a at the head can transmit corresponding data to the reconnection control device B through the processor 10 and the wireless communication module 20 of the device, the reconnection control device B and the reconnection control device C serve as an intermediate transmission link, and finally transmit the corresponding data to the wireless communication module 20 of the reconnection control device D at the tail, and then the processor 10 of the reconnection control device D performs data processing.
That is, since any 1 wireless communication module 20 can perform wireless communication with the wireless communication module 20 in the adjacent relay control device, these wireless communication modules 20 can form a wireless communication network of the entire vehicle.
In addition, when the wireless communication module 20 is used for wireless communication, the specific data content to be transmitted can be set and adjusted according to actual needs, and the wireless communication module 20 supports high-speed transmission of a large amount of data, so that transmission of a large amount of data needing interaction in different reconnection vehicle groups, for example, transmission of video stream data including train monitoring data and the like, can be realized by the wireless communication module 20 at high speed.
In practical applications, the processor 10 may be connected to the wireless communication module 20 through a PCIe (Peripheral Component Interconnect Express) interface circuit, the rate of the PCIe interface may be, for example, 2.5Gbps, and the wireless communication module 20 may support the 802.11b/g/n/ac standard or the 802.11b/g/n/ac/ax standard, the radio frequency bandwidth of the wireless communication module 20 can reach 160MHz, and a higher-order 256QAM modulation technique may be provided, and the maximum transmission rate can reach 867Mbps.

The data volume that MVB communication module 30 can transmit is less, but the reliability is higher, and when wireless communication module 20 and ethernet communication module 40 all break down, each reconnection control device can still realize the data interaction between the on-vehicle equipment in the reconnection train group that oneself is located through MVB communication module 30.
In one embodiment of the present invention, referring to fig. 2, the mvb communication module 30 may be connected to the processor 10 through a programmable logic circuit 50 for interface conversion.
This embodiment is to take into account that the processor 10 in some cases usually has no relevant interface to directly connect to the MVB communication module 30, and therefore, the programmable logic circuit 50 is provided to perform interface conversion. For example, in the embodiment of fig. 2, the processor 10 is connected to the programmable logic circuit 50 via an EMI bus, and the programmable logic circuit 50 is connected to the MVB communication module 30 via an MVBC bus.
In an embodiment of the present invention, considering that ESD (Electrical Short Distance) and EMD (Electrical medium Distance) are commonly used 2 communication media, in this embodiment, the transmission bus of the MVB communication module 30 may be selected as an EMD transmission bus or an ESD transmission bus.

The ethernet communication between the adjacent ethernet communication modules 40 is wired communication, and a large amount of transmission including video stream data can also be realized.
In practical applications, the ethernet communication module 40 with a communication rate of hundreds of mega and even giga can be selected. When wireless communication fails, communication inside a multi-consist or communication between different multi-consist groups can be completed by the Ethernet communication module.

N is a positive integer not less than 2, and by arranging N paths of Ethernet communication units, the independent work of N paths of Ethernet can be realized, and the reliability and flexibility of data transmission are further improved, namely when a single path of Ethernet fails, the normal work of other paths of Ethernet is not influenced. For example, in one particular scenario, N is set to 3, i.e., 3 Ethernet networks may communicate simultaneously. In the embodiment of fig. 2, the processor 10 is connected to the ethernet communication module 40 through an MII bus.
In an embodiment of the present invention, each of the plurality of overlapping control apparatuses may further include:
a memory 60 coupled to the processor 10 for data storage.
The memory 60 can be used for storing required data, so that the usability of the reconnection control device is improved, and in practical application, a large-capacity memory 60 is usually selected, so that the memory 60 can effectively store train monitoring data requiring a large amount of space. Of course, in other embodiments, other desired data may be stored in the memory 60 in the reconnection control apparatus in addition to the train monitoring data.
In a specific embodiment of the present invention, the power supplies of the multiple connection control devices may each include a first power supply and a second power supply that are redundant to each other, that is, for any 1 multiple connection control device, the first power supply and the second power supply may simultaneously supply power, so that when any power supply fails, the other power supply may also ensure the power supply reliability of the multiple connection control device.
In one embodiment of the present invention, the processor 10 is further configured to:
detects the fault state of the wireless communication module 20, the MVB communication module 30 and the Ethernet communication module 40 which are in communication connection with the self, and outputs the fault detection result.
In the scheme of this application, combine multiple communication technology, realized the redundancy on the communication mode, ensured the communication reliability of reconnection train. The embodiment further considers that the processor 10 can also perform fault state detection of the wireless communication module 20, the mvb communication module 30 and the ethernet communication module 40, and can output a fault detection result, so that a worker can know the fault condition of each module more timely and conveniently.
In addition, when a certain communication mode fails, for example, when 1 or more wireless communication modules 20 fail, the switching may be automatic or manual, and a specific switching rule may be selected according to actual needs. For example, when one or more wireless communication modules 20 fail, the communication mode may be automatically switched to the ethernet mode, and for example, the staff may perform manual setting, so that the communication inside the multi-consist car group is the MVB communication, and the communication between different multi-consist car groups is the ethernet communication.
For example, in an embodiment of the present invention, the processor 10 may display the fault detection result through a display device, so that a worker can more intuitively and conveniently see the fault detection result. In addition, in practical application, the display device may be an additionally arranged display device or an existing display device in a train. For example, in one specific embodiment, the display device may be a display device used by the train central control system, that is, the display device of the train central control system is directly used to display the fault detection result in the above embodiment, thereby effectively reducing the implementation cost of the scheme.

This embodiment considers that, when performing the driving control, a part of the actions needs to be performed cooperatively by the relevant devices of the whole vehicle, such as performing operations of braking, towing, and the like of the train, and a part of the actions may only need to be performed in a part of the cars, such as controlling the doors of the part of the cars to open.
Therefore, the embodiment considers that 1 of the multiple reconnection control devices can be the main reconnection control device, and the rest are the slave reconnection control devices, so that the cooperative control of each slave reconnection control device can be performed under the unified command of the main reconnection control device, the cooperative control of the train is effectively realized, and the driving safety is guaranteed.
The selection of the specific master reconnection control device can be set according to needs, for example, considering that a driver is usually located in a driver control room of the train head, so that the reconnection control device in the driver control room of the train head at present can be used as the master reconnection control device.
In an embodiment of the present invention, the wireless communication module 20 of the master reconnection control apparatus may further be configured to:
under the control of the processor 10, wireless communication is made with a ground control system.
This embodiment considers that the train generally needs to perform train-ground communication, and if the wireless communication module 20 of each reconnection control device is provided with a train-ground communication function, the cost is high. Therefore, in this embodiment, the wireless communication module 20 of the main reconnection control apparatus is provided with a vehicle-ground communication function, so that the wireless communication module 20 of the main reconnection control apparatus can perform wireless communication with the ground control system under the control of the processor 10. It should be understood that when the slave reconnection control apparatus has data to transmit to the ground, the data may be collected in the master reconnection control apparatus and transmitted by the wireless communication module 20 of the master reconnection control apparatus.
