Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow chart of a method for transmitting data between trains according to a first embodiment of the present invention. The embodiment can be applied to the condition of effectively transmitting data in the process of train traveling. The method of the embodiment can be executed by a device for transmitting data between trains, and the device can be realized by adopting a hardware/software mode and can be configured in electronic equipment. The inter-train data transmission method can be achieved according to any embodiment of the application. As shown in fig. 1, the method specifically includes the following steps:
and S110, determining the data to be transmitted of the current train.
In this embodiment, the current train is a rail train in progress, such as a heavy load. In the process of running of the train, the train needs to perform communication interaction with the ground in real time to ensure the path allocation of running trains on the track, and when the communication between the running train and the ground is interrupted, the running safety of other trains on the track may be influenced.
In this embodiment, optionally, the data to be transmitted includes at least one of the following: train position, train speed, network information, wind pressure, train number and train number. The train position is coordinate information of the current train in a world map; the train speed is the current running speed of the train or the average speed in a preset time period; the network information is a signal communication resource in a local area network where the train is located at present, and the communication state between the train and the ground can be known in real time according to the network information; specifically, the data to be transmitted may further include a transponder number and an estimation front end.
And S120, taking the candidate communication equipment in the working state in the current train as target communication equipment.
In the prior art, the traveling train mainly depends on the GSM-R network coverage form to transmit communication data in the communication process, namely, each position of the train can receive signals sent by two adjacent base stations in the traveling process, so that seamless coverage is realized; however, in the above data transmission, each train uses only one communication device to receive and transmit data at a time, and when the connection of the communication device is interrupted, the connection of the corresponding backup device is over time, so that the data is difficult to be transmitted effectively.
Therefore, at least two communication devices are installed in the travelling train in the embodiment, so that the problem that data transmission fails due to transmission failure of a single communication device is effectively solved. Communication equipment in the current train may also have faults, so that the communication equipment in a working state needs to be selected firstly to realize effective transmission of data; the communication device in this embodiment may be a communication station.
And S130, transmitting the data to be transmitted to the adjacent trains in parallel through the target communication equipment.
In this embodiment, the target communication device is at least one, and when the target communication device is one, the target communication device is used to transmit the received information to be transmitted to the adjacent trains in a classified manner; when the target communication equipment is a plurality of communication equipment, simultaneously adopting the plurality of communication equipment to carry out data transmission; if two adjacent trains are difficult to directly communicate, the data to be transmitted can be transmitted to the transfer radio station through the target communication equipment, and then the data is transmitted to the adjacent trains through the transfer radio station, so that the information between the two adjacent trains can be effectively transmitted. Specifically, since the train in this embodiment is in a traveling state, the adjacent train can select a traveling or stopped train within a preset range from the traveling train.
Determining data to be transmitted of a current train; taking candidate communication equipment in a working state in the current train as target communication equipment; and transmitting the data to be transmitted to the adjacent trains in parallel through the target communication equipment. According to the embodiment of the invention, the data to be transmitted are transmitted in parallel according to the number of the vehicle-mounted communication devices, so that the transmission efficiency of the data between trains can be effectively improved.
Example two
Fig. 2 is a schematic flow chart of a method for transmitting data between trains according to a second embodiment of the present invention. The embodiment is further expanded and optimized on the basis of the embodiment, and can be combined with any optional alternative in the technical scheme. As shown in fig. 2, the method includes:
and S210, determining data to be transmitted of the current train.
And S220, taking the candidate communication equipment in the working state in the current train as target communication equipment.
In this embodiment, optionally, before taking the candidate communication device in the working state in the current train as the target communication device, the method in this embodiment further includes:
acquiring heartbeat signals of each candidate communication device in the current train;
and if the heartbeat signal of the candidate communication equipment is detected in the preset time period, determining that the candidate communication equipment is in the working state.
Before selecting the target communication device, the embodiment needs to determine whether the candidate communication device normally operates, so as to ensure effective transmission of communication data.
The heartbeat signals of the candidate communication devices can be acquired by the control device in the train, the heartbeat signals can directly reflect whether the communication devices normally operate or not, and the operating state of the communication devices can be directly and quickly detected by the heartbeat signals.
Or, mutually acquiring heartbeat signals by each adjacent communication device, and intensively reflecting the acquisition result to the control device, so that the control device obtains the current heartbeat signal of each communication device according to the reflection result of each communication device.
Specifically, when judging whether each communication device has a heartbeat signal, a certain detection time period can be set, and if the heartbeat signal of the communication device is detected in the time period, it is indicated that the communication device can normally operate and has data operation; if the heartbeat signal of the communication equipment is not detected in the period, the communication equipment is in a fault state, and the data transmission work is difficult to effectively carry out.
This embodiment is through detecting each communications facilities's heartbeat signal to judge whether this communications facilities is in operating condition, thereby avoid being difficult to carry out effective transmission to this data in real time when the communications facilities who is in the fault state receives the data transmission instruction in data transmission process, thereby make the data of transmission incomplete.
And S230, according to the number of the target communication devices, fragmenting the data to be transmitted to obtain the data fragment packets.
In this embodiment, multiple target communication devices need to be used to implement parallel transmission of data, so as to solve the problem that data transmission fails due to damage of a single communication device. Combining data received from an external network with data of a train to serve as data to be transmitted, and carrying out fragmentation processing on the data to be transmitted according to the number of target communication devices to obtain data fragment packets; in this embodiment, to ensure the secure transmission of data, each data fragment to be transmitted may also be encrypted, so that the data is not stolen in the transmission process.
In this embodiment, optionally, the data to be transmitted is received through at least two transmission networks.
In this embodiment, a plurality of network base stations are used to implement separate transmission of data, so that a communication device receiving data can directly correspond to one network to receive data, thereby improving the data receiving efficiency.
For example, the present embodiment takes two network base stations, two networks (red network and blue network) for data transmission as an example; wherein different types of data are transmitted in the red network and the blue network.
The two communication devices are respectively connected to the red network base station and the blue network base station, and are respectively connected to the ATP, and are designated to receive a network of data independently, for example, a first target communication device receives red network data; the second target communication equipment receives the blue-net data; and the first target communication equipment and the second target communication equipment realize an interactive state through heartbeat information. After receiving the red and blue network data, the first target information device and the second target communication device of the current train send the red and blue network data to the transfer radio station, and the transfer radio station sends the red and blue network data to the third target information device and the fourth target information device in the adjacent train, so that the third target information device and the fourth target information device send the red and blue network data to the ATP of the train, and the data are effectively transmitted in the advancing process of the train.
Specifically, when the heartbeat between the first target information device and the second target information device disappears, the first target information device receives the red-blue two-network information from the ATP.
If the first target information equipment only receives the information of the red network from the ATP, the first target information equipment sends the information of the red network; if the vehicle radio station A only receives the information of the blue net from the ATP, the vehicle radio station A sends the information of the blue net; and if the first target information equipment receives the information of the red and blue networks from the ATP, the first target information equipment sends the information of the red and blue networks.
When the heartbeat between the second target information device and the first target information device disappears, the second target information device receives the red and blue two-network information from the ATP.
If the second target information device only receives the information of the red network from the ATP, the second target information device sends the information of the red network; if the second target information equipment only receives the information of the blue network from the ATP, the second target information equipment sends the blue network information; and if the second target information equipment receives the information of the red and blue networks from the ATP, the second target information equipment sends the information of the red and blue networks.
In this embodiment, optionally, the method of this embodiment further includes: the number of target communication devices is determined based on the number of transport networks. The number of the target communication networks is set to be the same as the data of the transmission network, so that the effect of complete butt joint of one target communication device and one party network can be realized, and the workload of data fragmentation is reduced.
And S240, distributing the data fragment packets to at least two target communication devices.
In the present embodiment, by dispersedly distributing the data packets to a plurality of target communication apparatuses, the transmission pressure of a single transmission of the target communication apparatuses can be reduced.
And S250, transmitting the data fragment packet to an adjacent train through at least two target communication devices.
In this embodiment, since a plurality of target communication devices need to transmit data to be transmitted, in order to reduce resource consumption of a train, the number of target communication devices for single transmission may be set, and each data fragment packet is sequentially transmitted to an adjacent train in batches. The embodiment can effectively improve the transmission rate of the data to be transmitted while transmitting the data in real time.
On the basis of the foregoing embodiment, optionally, the method of this embodiment further includes:
acquiring resource data of target communication equipment in a current train; the resource data at least comprises an operation memory of the target communication equipment;
and determining the number of the target communication equipment in the current train according to the resource data and the preset data number association table.
In this embodiment, the operation carrying capacity of each target communication device has a significant influence on data transmission, and therefore, when determining the number of target communication devices, the resource operation data of each target communication device needs to be considered to reasonably allocate transmission work of each target communication device. The preset data quantity association table stores the corresponding relationship between the resource data and the quantity. The embodiment determines whether the target communication device is used as a carrier for data transmission by combining the resource data of the target communication device, so that each communication device can be reasonably utilized, and the unified maintenance of each communication device is facilitated.
