Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a communication management method for a motor train unit according to an embodiment of the present invention, where the communication management method includes:
step S11: dividing an Ethernet cable penetrating through a target motor train unit into a plurality of virtual local area networks based on a VLAN technology;
step S12: and acquiring communication data in each virtual local area network to obtain target communication data, and performing communication management on the target motor train unit by using the target communication data.
In the invention, firstly, an Ethernet cable penetrating through a target motor train unit is divided into a plurality of Virtual Local Area Networks (VLANs) based on a Virtual Local Area Network (VLAN) technology. Because the Ethernet cable in the target motor train unit can work in different network segments by using the virtual local area network, the virtual local area network can be used for networking equipment and users in different physical positions.
After the Ethernet cable penetrating through the target motor train unit is divided into a plurality of virtual local area networks by using a VLAN technology, communication data in each virtual local area network can be obtained; then, all communication data of the target motor train unit, namely the target communication data, can be obtained by summarizing the communication data in each virtual local area network. It is conceivable that, when the target communication data of the target motor train unit is obtained, the target motor train unit is subjected to communication management by using the target communication data.
It should be noted that, since the focus of the embodiment is to explain how to obtain all the communication data of the target motor train unit by using one set of ethernet cables, and the process of performing communication management on the target motor train unit by using all the communication data of the target motor train unit is common knowledge of those skilled in the art, detailed description thereof is omitted here.
Obviously, in the embodiment, since all communication data of the target motor train unit can be obtained by using one set of ethernet cable, compared with the prior art in which all communication data of the target motor train unit can be obtained by using two sets of mutually independent ethernet cables, the method provided by the embodiment can significantly reduce the number of the ethernet cables required in the process of building the communication network of the target motor train unit, and can also reduce the communication wiring cost of the motor train unit.
As can be seen, in this embodiment, first, the ethernet cable penetrating through the target motor train unit is divided into a plurality of virtual local area networks based on the VLAN technology; and then, communication data in each virtual local area network are obtained to obtain target communication data, and the target communication data are used for carrying out communication management on the target motor train unit. Obviously, in the process of acquiring all communication data in the target motor train unit, the ethernet cable penetrating through the target motor train unit is divided into the plurality of virtual local area networks by using the VLAN technology, so that the communication data corresponding to the virtual local area networks can be acquired from any one of the virtual local area networks, and finally, the communication data in each virtual local area network is summarized, so that all the communication data, that is, the target communication data in the target motor train unit can be acquired. Obviously, in the process of acquiring all the communication data of the target motor train unit, all the communication data of the target motor train unit can be acquired only by using one set of ethernet cables penetrating through the target motor train unit, and compared with the prior art that the communication data of the target motor train unit can be acquired only by using two sets of mutually independent ethernet cables, the method in the embodiment can significantly reduce the wiring quantity of the ethernet cables required in the process of building the communication network of the target motor train unit and can also reduce the communication wiring cost of the motor train unit.
Based on the foregoing embodiments, this embodiment further describes and optimizes the technical solution, specifically, in step S11: based on VLAN technique, after the process of dividing the Ethernet cable penetrating through the target motor train unit into a plurality of virtual local area networks, the method also comprises the following steps:
and setting a data interaction speed limit value for a communication port of the switch in each virtual local area network.
In this embodiment, in order to avoid that the normal network communication process of the virtual local area network is affected by a large data interaction amount when the switch in the virtual local area network performs data interaction, in this embodiment, a data interaction speed limit value is further set at a communication port of the switch in each virtual local area network.
That is, the ingress rate and the egress rate in the switch communication port in each virtual lan are limited, and in the process of setting the data interaction speed limit value of the switch communication port, the data interaction speed limit value of the switch communication port can be limited according to different practical application scenarios. Such as: the data interaction speed limit of the communication port of the switch can be set according to the data flow of the PIS (passenger information System) and the data flow of the equipment maintenance.
It can be understood that when the communication network in the target motor train unit is abnormal, the number of the broadcast packets in the communication network may be increased sharply, so that the normal operation of the virtual local area network is affected, and even impact is caused to the terminal device. That is, when the broadcast packets received by the communication port of the switch are accumulated to reach the preset value, the communication port of the switch can automatically discard the received broadcast packets, so that the influence on the terminal equipment can be relatively avoided.
Therefore, the technical scheme provided by the embodiment can further ensure the overall stability of the target motor train unit in the data communication process.
As a preferred embodiment, the above steps: the process of setting data interaction speed limit value for the communication port of the switch in each virtual local area network comprises the following steps:
reserving a preset allowance for the communication port of the switch in each virtual local area network, and setting a data interaction speed limit value for the communication port of the switch in each virtual local area network.
In practical application, in order to further ensure the accuracy and reliability of the set value of the data interaction speed limit value of the communication port of the switch in each virtual local area network, a preset margin may be reserved in advance for the communication port of the switch in each virtual local area network before the data interaction speed limit value is set for the communication port of the switch in each virtual local area network, so as to avoid the impact on the communication port of the switch caused by the abnormal emergency.
Specifically, a margin of 20% to 50% may be reserved for the communication port of the switch in each virtual local area network, and then a data interaction speed limit value may be set for the communication port of the switch in each virtual local area network. Of course, the value of the preset margin can also be adaptively adjusted according to different actual situations, and is not described in detail herein.
Based on the above embodiment, the embodiment further describes and optimizes the technical solution, and specifically, the communication management method for a motor train unit further includes:
if the communication data in the target virtual local area network cannot be acquired, prompting early warning information;
the target virtual local area network is any one of a plurality of virtual local area networks.
It can be understood that, in practical application, the virtual local area network in the target motor train unit may be abnormal, so that normal communication of the target motor train unit is affected, and therefore, in this embodiment, if communication data in the target virtual local area network cannot be acquired in the process of acquiring communication data in each virtual local area network, it is indicated that a certain communication device in the target virtual local area network is abnormal. Under the condition, in order to enable the staff to timely learn the current communication state of the target motor train unit, the early warning information can be prompted, so that the staff can timely overhaul and maintain the target virtual local area network, and further more economic losses of the target motor train unit are reduced.
Therefore, the safety and the reliability of the target motor train unit in the communication process can be further ensured through the technical scheme provided by the embodiment.
Based on the foregoing embodiments, this embodiment further describes and optimizes the technical solution, specifically, in step S11: based on VLAN technology, the process of dividing the Ethernet cable penetrating through the target motor train unit into a plurality of virtual local area networks comprises the following steps:
and based on the VLAN technology, dividing the Ethernet cable penetrating through the target motor train unit into a plurality of virtual local area networks according to a preset dividing rule.
In practical application, in the process of dividing the ethernet cable of the target motor train unit into the plurality of virtual local area networks, the ethernet cable of the target motor train unit may be divided into the plurality of virtual local area networks according to a preset division rule.
Specifically, the virtual local area network may be divided according to ports of each communication device in the target motor train unit, or the virtual local area network may be divided according to MAC addresses of each communication device in the target motor train unit, or the virtual local area network may be divided by communication devices with the same working performance in the target motor train unit, and so on. Obviously, by the method, the flexibility in the process of dividing the Ethernet cables of the target motor train unit can be further improved.
Based on the foregoing embodiments, this embodiment further describes and optimizes the technical solution, specifically, in step S11: based on VLAN technology, the process of dividing the Ethernet cable penetrating through the target motor train unit into a plurality of virtual local area networks comprises the following steps:
based on VLAN technology, according to TCMS, PIS, freight information management system and fault diagnosis system in the target motor train unit, the Ethernet cable penetrating through the target motor train unit is divided into a first virtual local area network, a second virtual local area network, a third virtual local area network and a fourth virtual local area network.
It can be understood that, because the TCMS (Train Control and management system), the PIS, the freight information management system and the fault diagnosis system in the target motor Train unit are existing data communication systems with mature technology in the target motor Train unit, if the ethernet cable of the target motor Train unit is divided into the first virtual local area network, the second virtual local area network, the third virtual local area network and the fourth virtual local area network according to the TCMS, the PIS, the freight information management system and the fault diagnosis system in the target motor Train unit, a process that a worker collects data information in an earlier stage to perform networking on each device in the target motor Train unit can be omitted, and the obtained data information in each virtual local area network can be more comprehensive and orderly.
Therefore, by the technical scheme provided by the embodiment, convenience in dividing the Ethernet cable of the target motor train unit can be relatively improved.
