Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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.
The train operation diagram is a diagram for representing the operation time of a train in each section of a railway and the arrival or passing time of each station by using a coordinate principle, and is the basis of train operation. In the scenes of troubleshooting, train diagram adjustment and the like, the problem is usually located and analyzed by using historical change data of the train diagram, but the method is based on a large amount of actual operation experience, which not only needs a large amount of time, but also cannot clearly display position information, arrival time, departure time, passing time and the like of the train.
In view of the above situation, the present invention provides a method for searching for a change in a train diagram, and fig. 1 is a schematic flow diagram of the method for searching for a change in a train diagram provided in an embodiment of the present invention, as shown in fig. 1, the method includes:
specifically, before searching for a problem through the historical change data of the train operation diagram, a time range of the historical change data of the train operation diagram to be searched, namely a time range to be searched, needs to be determined, and the historical change data of the train operation diagram, namely an operation diagram change data packet. Here, the time range to be searched may be directly sent by the user, or may be determined according to the occurrence time of the fault sent by the user, which is not specifically limited in the embodiment of the present invention.
in order to solve the problem that the problem of searching for the historical change data through the train operation diagram is time-consuming and labor-consuming in positioning due to the fact that the problem is found based on actual operation experience in the traditional scheme, the received operation diagram change data packets are stored according to the receiving sequence of the operation diagram change data packets, so that the operation diagram change data packets needing to be searched can be directly selected from the prestored operation diagram change data packets according to the time range to be searched when troubleshooting is conducted.
Specifically, after receiving the runtime graph change data packets, storing the runtime graph change data packets to a file according to the receiving sequence of the runtime graph change data packets. The recording start-stop time of each runtime map change data packet is stored in the file header of each file, the recording start-stop time comprises recording start time and recording stop time, the recording start time in the file header of the corresponding file can be determined according to the time of receiving the runtime map change data packet stored in each file firstly, and the recording stop time in the file header of the corresponding file can be determined according to the time of receiving the runtime map change data packet stored in each file latest.
And then, selecting a file matched with the time range to be searched from the files storing the plurality of the operation graph change data packets according to the time range to be searched and the record starting and ending time in the file header of each file stored in advance, and taking the selected file as a target file.
It should be noted that, because the size of the time range to be searched is not fixed, the number of the target files selected according to the time range to be searched is also not fixed, and may be one or multiple, and this is not specifically limited in the embodiment of the present invention.
And step 130, analyzing each operation diagram change data packet in the target file to obtain and display the data content of each operation diagram change data packet in the target file.
When the problem is found in the traditional scheme, the position information, the arrival time, the departure time, the passing time and the like of the train cannot be clearly displayed. Therefore, in the embodiment of the invention, after the target file is determined, the data content of each operation diagram change data packet in the target file can be displayed, so that developers can clearly and intuitively acquire the position information, the arrival time, the departure time, the passing time and the like of the train.
Before displaying the data content of each runtime graph change data packet in the target file, each runtime graph change data packet in the target file needs to be analyzed, for example, the corresponding runtime graph change data packet may be analyzed according to an analysis protocol corresponding to each runtime graph change data packet, and the data content of each runtime graph change data packet is obtained after the analysis is completed.
And then, displaying the data content of each operation graph change data packet in the obtained target file. In consideration of the uncertainty of the number of data packets and the size of the data packets of the runtime graph change data packet contained in the target file, in order to improve the efficiency of problem finding, multiple display modes, such as a single step mode and a double speed mode, may be set during specific display. The display modes and the display speeds under different display modes are different, and the problem searching efficiency is improved by setting different display modes to assist in searching the problems.
According to the train operation diagram change searching method provided by the embodiment of the invention, after the operation diagram change data packets are received, the operation diagram change data packets are stored into the files according to the receiving sequence, and the recording start-stop time in the file header of the corresponding file is determined according to the time of receiving the operation diagram change data packets firstly and lastly in each file; in order to determine a target file from each file according to a predetermined time range to be searched and the record starting and stopping time in the file header of each file stored in advance when troubleshooting is performed; the defects that time and labor are consumed for positioning through historical change data of a train operation diagram in the traditional scheme are overcome; and the data content of each operation diagram change data packet in the analyzed target file is displayed, so that the related information of the train can be clearly and visually acquired, and the efficiency of searching the problems is improved.
Based on the above embodiment, in step 130, obtaining and displaying the data content of each runtime graph change data packet in the target file includes:
if the current display mode is the speed-multiplying mode, determining the display data volume in unit time based on the playback speed in the speed-multiplying mode and the number of the data packets of the operation diagram change data packets contained in the target file;
and sequentially displaying the data content of each operation graph change data packet in the target file based on the display data volume in unit time.
Specifically, in step 130, when the data content of each runtime graph change data packet in the target file obtained by analysis is displayed, different display modes may be selected. Such as a double speed mode and a single step mode. The multiple speed mode corresponds to multiple playback speeds, such as double speed, quadruple speed, double-dot and quintuple speed, and the like. If the currently selected display mode is the double-speed mode, the display data amount to be displayed in unit time can be determined according to the playback speed in the double-speed mode and the number of the data packets of the operation graph change data packets contained in the target file. For example, if the playback speed in the currently selected double speed mode is double speed, the number of packets of the runtime map variation packets included in the target file is 10, the sum of the packet sizes of the 10 runtime map variation packets included in the target file is 10G, and the presentation is required to be completed within 1 hour, the presentation data amount to be presented per second is 2.778 MB/s.
And then sequentially displaying the data content of each operation graph change data packet in the target file according to the determined display data volume in the unit time and the receiving sequence of each operation graph change data packet in the target file.
Based on the above embodiment, in step 130, analyzing each runtime graph change data packet in the target file to obtain and display the data content of each runtime graph change data packet in the target file, including:
if the current display mode is the single-step mode, each time a single-step playback command is received, analyzing a running chart change data packet from the target file to obtain the data content of the running chart change data packet for displaying.
Specifically, when the data content of each runtime diagram change data packet in the target file is displayed in step 130, if the currently selected display mode is the single-step mode, each time a single-step playback instruction is received, one runtime diagram change data packet in each runtime diagram change data packet included in the target file is analyzed to obtain the data content of the analyzed runtime diagram change data packet, and the data content of the parsed runtime diagram change data packet is displayed. The single-step playback instruction may be a click operation of a user, or may also be an analysis instruction sent by the user, which is not specifically limited in this embodiment of the present invention.
It should be noted that, in the single-step playback mode, the runtime map change data packets in the target file are not necessarily analyzed according to the receiving sequence of the runtime map change data packets. For example, the previous single-step playback instruction may instruct the 1 st runtime graph change data packet in the target file to be parsed, and the single-step playback instruction received at the current time may instruct the third runtime graph change data packet in the target file to be parsed.
Based on the above embodiment, in step 130, analyzing each runtime graph change data packet in the target file includes:
analyzing each operation diagram change data packet in the target file based on the analysis protocol corresponding to each operation diagram change data packet in the target file;
the resolution protocol is determined based on the storage mode of the corresponding operation diagram change data packet.
Specifically, after the target file is determined from the pre-stored files through step 120, the runtime graph change data packages in the target file need to be analyzed. Because the data contents contained in different runtime map change data packets are different, when the runtime map change data packets are stored, different storage modes can be adopted for the different runtime map change data packets, and the storage mode of each runtime map change data packet corresponds to the analysis mode thereof. Therefore, before analyzing each runtime graph change data packet in the target file, an analysis protocol corresponding to the runtime graph change data packet needs to be determined according to a storage mode of each runtime graph change data packet in the target file.
Then, the corresponding runtime diagram change data packet can be analyzed according to the analysis protocol of each runtime diagram change data packet in the target file, for example, if the analysis protocol of the 1 st runtime diagram change data packet is the a protocol, the analysis protocol of the 2 nd runtime diagram change data packet is the B protocol, and the analysis protocol of the 3 rd runtime diagram change data packet is the C protocol, the 1 st runtime diagram change data packet can be analyzed according to the a protocol of the 1 st runtime diagram change data packet; analyzing the 2 nd operation chart change data packet according to the protocol B of the 2 nd operation chart change data packet; and analyzing the 3 rd operation chart change data packet according to the protocol C of the 3 rd operation chart change data packet.
Based on the above embodiment, the process of finding a problem by running a graph to change a data packet is described by taking the line 5 of the subway in city a as an example.
Specifically, each of the runtime map change packets is defined to include a reception time of 4 bytes in length, a packet length of 4 bytes in length, and a data content of m bytes in length. Each file storing a plurality of runtime map change data packets is defined to include a file header of 16 bytes and a file body, and the file body corresponds to each runtime map change data packet stored in the file. The 16-byte header of each file contains a recording start time of 4 bytes, a recording end time of 4 bytes, a file length of 4 bytes, and the number of packets of 4 bytes.
The file format of each file is shown in the following table:
and during the on-line period of the runtime diagram software, storing the received runtime diagram change data packets into files according to the receiving sequence of the runtime diagram change data packets, storing the record start-stop time of each runtime diagram change data packet in the file header of each file, and determining the record start-stop time in the file header of the corresponding file according to the time of receiving the runtime diagram change data packets firstly and latest in each file.
After the software is switched to a playback mode, clicking a button for selecting a playback file, popping up a file selection frame, and selecting a target file from the files according to a time range to be searched and the pre-stored record starting and ending time in a file header of each file; and selecting a target file from the file selection box and importing the target file. And then, analyzing each operation diagram change data packet in the target file, displaying the receiving time of each operation diagram change data packet after the analysis is finished, clicking a playback starting button, and sequentially sending the operation diagram change data packets to the operation diagram module of the software according to the sequence of the receiving time from small to large by using a cycle timer with the time length of 1 second so that the operation diagram module plays back according to the received operation diagram change data packets.
It should be noted that, during playback, the playback speed can be changed by changing the step length of the progress bar advancing within one second, so as to realize double-speed playing. In addition, during playback, single-step playback can be selected, a single-step playback button is clicked, a cycle timer is paused, the single-step button is clicked once, and the running chart change data packet is analyzed and played back once; and clicking a play stop button, emptying the analyzed operation diagram change data packet in the software, and waiting for the next selection of the target file, the analysis and playback of each operation diagram change data packet in the target file and the like.
According to the train operation diagram change searching method provided by the embodiment of the invention, after the operation diagram change data packets are received, the operation diagram change data packets are stored into the files according to the receiving sequence, and the recording start-stop time in the file header of the corresponding file is determined according to the time of receiving the operation diagram change data packets firstly and lastly in each file; in order to determine a target file from each file according to a predetermined time range to be searched and the record starting and stopping time in the file header of each file stored in advance when troubleshooting is performed; the defects that time and labor are consumed for positioning through historical change data of a train operation diagram in the traditional scheme are overcome; and the data content of each operation diagram change data packet in the analyzed target file is displayed, so that the related information of the train can be clearly and visually acquired, and the efficiency of searching the problems is improved.
Based on the above embodiment, the method further comprises:
receiving a running chart change data packet, and determining the data packet length of the received running chart change data packet;
if the sum of the length of the character string of the current character string and the length of the data packet is less than or equal to a preset length threshold value, writing the received operation graph change data packet into the tail part of the current character string;
otherwise, writing the current character string into a newly-built file for storage, writing the received runtime graph change data packet into the newly-built character string, and taking the newly-built character string as the current character string.
Specifically, before searching for a problem through the history change data of the train operation diagram, that is, the operation diagram change data packet, needs to be acquired, and the operation diagram change data packet is stored in a file.
In view of the fact that the data packets of the runtime map change data packets are different in size, in order to make the runtime map change data packets stored in the files relatively uniform, the size of the file can be fixed when the runtime map change data packets are stored.
Then, judging whether the sum of the data packet length of the running chart variable data packet to be stored and the character string length of the character string of the running chart variable data packet to be stored is greater than a preset length threshold value, wherein the preset length threshold value is a preset length upper limit according to actual requirements, and the character string of the running chart variable data packet to be stored is the current character string; if the sum of the length of the data packet of the operation diagram change data packet and the length of the character string of the current character string is smaller than or equal to the preset length threshold, the sum of the length of the character string of the current character string and the length of the data packet does not exceed the length upper limit, and the operation diagram change data packet can be written into the tail part of the current character string.
Correspondingly, if the sum of the length of the data packet of the running chart change data packet and the length of the character string of the current character string is larger than the preset length threshold, the sum of the length of the character string of the current character string and the length of the data packet exceeds the length upper limit, and the current character string cannot store the running chart change data packet, so that the running chart change data packet is written into a newly-built character string, the current character string is stored into a newly-built file, and the newly-built character string is updated into the current character string.
The train operation diagram change searching method provided by the invention has the advantages that after the operation diagram change data packets are received, when the operation diagram change data packets are stored into the files, a preset length threshold value is set, the operation diagram change data packets are correspondingly stored according to the relation between the sum of the length of the character string of the current character string and the length of the data packet of the operation diagram change data packet and the preset length threshold value, the operation diagram change data packets stored in each file are relatively balanced through fixing the length of the file during data storage, the condition that the single operation diagram change data packet is stored in a split mode is avoided, and the storage process of the operation change data packet is more complete.
Based on the above embodiment, writing the current character string into the newly created file storage includes:
generating a file header based on the record start-stop time, the number of data packets and the length of the character string of the operation diagram change data packets contained in the current character string;
and writing the file header and the current character string into a newly-built file for storage.
Specifically, after the sum of the length of the data packet and the length of the character string of the current character string is determined to be greater than a preset length threshold, a file header needs to be generated before the current character string is written into a newly-built file for storage, and the current character string and the file header are stored into the newly-built file.
The generation process of the file header can be to determine the record start-stop time of the runtime map variable data packet contained in the current character string according to the time of the runtime map variable data packet written first in the current character string and the time of the runtime map variable data packet written latest; determining the length of the character string of the current character string according to the length of the data packet of each operation graph change data packet contained in the current character string; and finally, determining the number of the data packets of the operation diagram change data packets contained in the current character string.
And then, generating a file header comprising the record start-stop time, the number of the data packets and the length of the character string of the current character string according to the record start-stop time, the number of the data packets and the length of the character string of the running chart change data packets contained in the current character string, wherein the length of the character string in the file header is the length of the file, and writing the generated file header and the current character string into a newly-created file for storage.
Based on the above embodiment, step 110 includes:
acquiring the occurrence time of a fault to be checked;
based on the occurrence time, a time range to be searched is determined.
Specifically, before searching for a problem through the historical change data of the train running diagram, the occurrence time of the fault needs to be determined, and since the occurrence time of the fault obtained at this time is not necessarily accurate and needs to be further checked, the occurrence time of the fault obtained at this time is determined as the occurrence time of the fault to be checked, and the occurrence time of the fault to be checked may be sent by a user or preliminarily determined according to the historical change data of the train running diagram, which is not specifically limited in the embodiment of the present invention.
After the occurrence time of the fault to be checked is determined, the time range of the historical change data of the train operation diagram to be searched, namely the time range to be searched, can be determined according to the occurrence time of the fault to be checked.
Based on the above embodiment, fig. 2 is a general flowchart of a train operation diagram change searching method provided by the embodiment of the present invention, and as shown in fig. 2, the method includes:
step 210, receiving a running chart change data packet, and determining the data packet length of the received running chart change data packet;
step 221, writing the received operation diagram change data packet into the tail part of the current character string;
step 222, generating a file header based on the record start-stop time, the number of data packets and the length of the character string of the operation diagram change data packets contained in the current character string;
step 224, writing the received runtime diagram change data packet into the newly created character string, and taking the newly created character string as the current character string;
step 250, determining a target file from each file based on the time range and the record starting and stopping time in the file header of each file stored in advance;
step 260, analyzing each operation diagram change data packet in the target file based on the analysis protocol corresponding to each operation diagram change data packet in the target file; the analysis protocol is determined based on the storage mode of the corresponding operation diagram change data packet;
