The method for constructing the differentiated access ICT fusion information transmission platform is described in detail below with reference to FIG. 1.
Fig. 2 is a schematic flowchart of a method for constructing a differentiated access ICT fusion information transmission platform according to an embodiment of the present application.
Referring to fig. 2, the method for constructing the differentiated access ICT fusion information transmission platform is described in detail as follows:
in step 201, the data processing tasks of all trains within the target area at a certain time in the future are acquired.
The target area is an area corresponding to a responsible range of the ICT fusion information transmission platform, and the target area can comprise a plurality of network blocks, the plurality of network blocks cover the whole target area, and the data processing task comprises a data transmission task and/or a data calculation task.
For example, the railway may be divided into a plurality of network blocks that are sequentially linked along the railway, where each network block includes at least one computing node, for example, an edge computing node, and each network block has a local communication network therein, so that data processing tasks such as data collection, storage, data computing, data communication transmission or forwarding may be performed.
For example, in step 201, a data processing task of the train in a future time may be determined according to a data processing history of the train traveling on the same road section and a trend of history monitoring data of the train.
For example, the data required to be transmitted through the network and the data required to be calculated and analyzed by a certain device on the train can be comprehensively judged at a certain future time (for example, after one minute) according to the historical record of the train or the train of the same model as the train running on the same road section (for example, the historical record of the data transmission and the data calculation requirement of the train of the same model through the same road section in the past 1 month), and the trend of the historical monitoring data of the train (for example, the trend that the fault rate of the certain device on the train is gradually improved according to the increase of the working period).
The running states of all trains in the target area can be predicted or estimated in advance. For example, the trajectory of a single train and the corresponding arrival and departure times; how many vehicles are currently in the target area; the number of demands that may need to be communicated or calculated at a time per train and specific parameter information, such as requirements for transmission packet loss rate, bandwidth, amount of data transmitted, transmission delay, etc.
In the step, train control information and on-board monitoring video of the train are updated in real time, and in principle, each network block needs to be configured with resource processing; the information of the rail transit passengers is distributed to the block to which the current position of the train belongs according to real-time requirements (such as the late time of the front vehicle, which possibly affects the schedule of the current train and needs to be informed of the passengers); road condition environment monitoring needs to be distributed to blocks of a special road section (geological disasters are easy to happen). All network blocks are linked through a full-exchange network, so that related data transmission and calculation tasks can be completed cooperatively.
In step 202, a resource allocation scheme for the data processing task of each train is determined according to the data processing task, the network block where each train is currently located, and the task processing capability of each network block.
The resource allocation scheme comprises a network block allocated to the data processing task of the train.
In some embodiments, the method for determining the resource allocation scheme of the data processing task for each train may be: if the task processing capacity of the network block where the train is located can not meet the data processing task of the train, key parameters of the remaining tasks which can not be completed are sent to a decision center, wherein the key parameters comprise one or more of network transmission data types, transmission quantity, transmission bandwidth requirements and communication delay requirements; for the data transmission requirements in the rest tasks, the decision center distributes links of a plurality of other network blocks to be transmitted to the destination in parallel; and for the data calculation requirements in the residual tasks, the decision center distributes the calculation nodes of a plurality of other network blocks for parallel processing, and sends the processing results to the destination.
For example, more computing tasks can be processed in parallel by a plurality of computing nodes and integrated by a full-switching network; tasks with high bandwidth requirements, such as video transmission, can be transmitted simultaneously to a destination via multiple forwarding links.
Referring to fig. 3, when the network block i simulates the task requirement of a future train, it finds that the data processing task of the train cannot be completed, and then the key parameters of the rest task information which cannot be completed are uploaded to a decision center, and task allocation is performed by the decision center according to the resource condition in the whole destination area.
In still other embodiments, in step 202, a resource allocation scheme for the data processing requirements of each train may be determined according to the task requirements, the network block in which each train is currently located, and the task processing capability of each network block, with the goal of minimum cost of data processing.
Wherein, the average value of task execution results in statistics history can obtain that the unavailability rate of the transmitted data is u due to the problems of network jitter, packet loss and the like when certain data is transmitted in a certain communication link i Which is assigned a weight of α and the delay generated by the network transmission at each node is d i Which is assigned a weight of β, the data is c at a computational cost (based on the computational time of the block general purpose computational node, e.g., the data requires the computational node to compute 500 milliseconds) i Which is assigned a weight of γ. The total cost of this data implementation is: cost (test) i ＝αu i+ βd i +γc i Each of the weights α, β, and γ is determined according to the application requirements, and α+β+γ=1.
Based on this, in one scenario, for a data transmission task with a high priority, the data transmission processing Cost of the train i is Cost i ＝αu i+ βd i ，u i D, for the unavailability of the transmitted data caused by the problem of network jitter and packet loss during transmission in a certain communication link i Delay generated at each node for network transmission, alpha is an unavailability weight, beta is a transmission delay weight, alpha + β ＝ 1, the total cost of all train data transmission is
n is the number of trains in the target area. And traversing all the distribution schemes of the trains to the data transmission tasks, calculating the total cost of each distribution scheme, and taking the distribution scheme with the minimum total cost as the final distribution scheme.
Specifically, for applications with small calculation amount requirements, small transmission bandwidth requirements and high reliability requirements, the priority is highest, and resource allocation is needed first, for example, a decision center controls data transmission of train running state monitoring information in the whole target area, and communication transmission can be considered to be mainly performed by adopting V-band millimeter waves. Considering that the requirement of computing resources is small, the computing cost Let γ=0, which is negligible. The unavailability weight α and the transmission delay weight β are determined according to the specific requirements of the train, for example, the α=β=0.5 is specified. With Cost i ＝αu i+ βd i The method comprises the steps of carrying out a first treatment on the surface of the Setting a Cost threshold D, defining a Cost i <D (preventing the transmission cost of monitoring a certain train running state from exceeding a regulation), a data transmission scheme of the information can be planned for all trains for a certain period of time (for example, after 1 minute). It should be noted that the requirement has a hard specified index for jitter, packet loss rate, transmission delay, etc. during transmission, and the planned transmission scheme related parameters should not be lower than the specified index.
The total cost of the information transmission of all the trains is
And traversing all possible allocation schemes of the transmission requirements of the train class, wherein the obtained minimum cost is the task allocation mode.
For example, two trains a and B in a certain area need to transmit train control information to a ground monitoring center at the same time, and the transmission indexes required by the train control information of the train a are as follows: packet loss rate < a1%, data jitter percentage < a2%, data availability (measuring reliability of transmitted data) > a3%, and transmission delay < a4 seconds; the transmission indexes required by train control information of the train B are as follows: packet loss rate < b1%, data jitter percentage < b2%, data availability (measure reliability of transmitted data) > b3%, and transmission delay < b4 seconds. When train A and B are screened for train control information transmission paths, indexes such as packet loss rate, data jitter, data availability, transmission delay and the like in history data of all alternative links are ensured to meet requirements of related trains, p1 links are arranged to meet the requirements of A and B, p2 links only meet the requirements of A, and p3 links only meet the requirements of B.
Traversing A, B column control information transmission combinations in links with indexes meeting requirements, wherein the following allocation schemes are adopted: scheme 1, a: p1, B: p3, according to the above formula, the total Cost of transmitting A, B column control information is Cost all1 The method comprises the steps of carrying out a first treatment on the surface of the Scheme 2, a: p2, B: p3, according to the above formula, the total cost of transmitting A, B column control information can be calculatedFor Cost all2 The method comprises the steps of carrying out a first treatment on the surface of the Scheme 3, a: p2, B: p1, according to the above formula, the total Cost of transmitting A, B column control information is Cost all3 . The scheme with the minimum total cost in the three schemes is the final distribution scheme. .
In another scenario, for a video monitoring task with a low priority, after the data transmission task is processed, the video monitoring task is subjected to resource allocation. The Cost of processing the video monitoring task by the train i is Cost i ＝αu i+ βd i +γc i ，u i D, for the unavailability of the transmitted data caused by the problem of network jitter and packet loss during transmission in a certain communication link i Delay generated at each node for network transmission c i The calculation cost required for application completion is alpha is an unavailability weight, beta is a transmission delay weight, gamma is a calculation cost weight, alpha + β+γ ＝ 1, the total cost of all train video monitoring tasks is
n is the number of trains in the target area. And traversing all the distribution schemes of the trains to the video monitoring task, calculating the total cost of each distribution scheme, and taking the distribution scheme with the minimum total cost as the final distribution scheme.
Specifically, for applications with larger bandwidth requirements, such as vehicle video monitoring, and lower reliability requirements, the priority is lower than the list control information, that is, the task allocation is performed after the list control monitoring transmission task allocation is processed, and the task allocation is matched with the E-band millimeter wave according to the characteristics of the task, so that the transmission can be considered to be performed by adopting the mode.
The task can select a plurality of forwarding paths in the full-switching network for simultaneous transmission according to the requirements, and each block is internally provided with a local communication network, so that the tasks such as data collection and storage, data calculation processing, data communication transmission or forwarding can be performed. The data transfer task from the train (e.g., a video file with a large amount of data) may optionally divide it into multiple portions while being forwarded to the destination over links of multiple blocks. The multi-path simultaneous forwarding can be performed through a load balancing strategy on the network, and related data computing services are distributed to computing nodes of each network block through the full-switching network by a decision center for processing.
For example, when the train runs, the collection and local storage of the original data of each vehicle-mounted subsystem are realized through a data acquisition device and a storage device which are deployed on the train. And then, transmitting data to ground analysis for decision by 5G communication equipment, such as vehicle-mounted millimeter wave E-band and V-band private network communication equipment, so as to realize the functions of state monitoring, fault early warning, health assessment and the like of the subsystem and key component states, and provide remote diagnosis and expert technical support for train operation. Because the train is always in running state, in order to ensure driving safety, remote diagnosis and technical support need timeliness, such as video record files of a locomotive running part and video records of bow net monitoring are uploaded, analysis and calculation are needed as soon as possible, and abnormal states are identified.
For the service demands of all trains, the values of alpha, beta and gamma can be defined according to the specific requirements, so that alpha+beta+gamma=1. For example, video monitoring of a locomotive pantograph requires higher reliability of video transmission than transmission of driver behavior monitoring video, and thus the unavailability weight of the pantograph monitoring video is higher than that of the driver behavior monitoring. It should be noted that all requirements have rigidly defined indexes for jitter, packet loss rate, transmission delay, calculation time consumption, etc. during transmission, and the planned transmission scheme related parameters should not be lower than the defined indexes.
According to the formula Cost i ＝αu i+ βd i +γc i The total cost of all train application requirements can be obtained, and the minimum cost obtained by traversing all possible allocation schemes is the task allocation mode.
In step 203, the data processing tasks of all trains within the target area are processed based on the allocation scheme.
After the allocation scheme is obtained, the data transmission tasks and the data calculation tasks of all trains in the target area can be processed according to the allocation scheme.
According to the method for constructing the differentiated access ICT fusion information transmission platform, the data processing tasks of all trains in the target area in a certain time in the future are obtained, the resource allocation scheme of the data processing tasks of all trains is determined according to the data processing tasks, the network blocks where all trains are currently located and the task processing capacity of each network block, the corresponding network blocks are allocated for the data processing tasks of all trains, and the cost optimization of all train data processing in the target area is achieved.
