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 application.

In the prior art, most train network control systems adopt an MVB communication protocol, and the MVB communication protocol has a small bandwidth of only 1.5Mbps at most and a low transmission speed.

Therefore, the embodiment of the application discloses a data processing method, which improves the data transmission speed, can avoid data loss and ensures the integrity and accuracy of data.

Referring to fig. 1, a data processing method disclosed in an embodiment of the present application includes:

s101: acquiring Ethernet data and MVB data for representing the operating state of a working system of each connection network of a train;

in this step, ethernet data and MVB data are respectively obtained through the ethernet port and the MVB port, and the ethernet data and the MVB data are used for representing the operating states of all the operating systems in the train. Specifically, the work system may include, but is not limited to: a train control system, a monitoring system, a traction system, a braking system, a fire alarm system, a passenger information system, a storage battery control system, a vehicle door control system and other network connection systems.

When the ethernet data and the MVB data are obtained, the ethernet data and the MVB data may be obtained periodically according to a preset duty cycle by using a preset application program, such as a CCU (central control Unit), an HMI (Human Machine Interface), or a preset process. The preset duty cycle may be set according to specific conditions during the implementation process, and this embodiment does not limit this.

It should be noted that, in the embodiment of the present application, the MVB data may specifically be data with a size of 32 bytes, and the first two bytes of the data are life signals for characterizing the MVB data. The size of the ethernet data may be determined according to the actual data size, with the first four bytes being the vital signal used to characterize the ethernet data.

S102: judging whether the Ethernet communication state is normal or not by utilizing the Ethernet data; if yes, go to step S103; if not, the step S104 is entered;

s103: determining the Ethernet data as target data, and entering step S106;

in the embodiment of the application, after the ethernet data and the MVB data are acquired, whether the ethernet communication state is normal at the present time is determined based on the ethernet data. If the Ethernet communication state is normal, the current Ethernet data is represented to be correct, and the current Ethernet data can be directly determined as the target data.

S104: judging whether the MVB communication state is normal or not by using the MVB data; if yes, go to step S105;

s105: determining the MVB data as the target data, and entering step S106;

if the ethernet communication state is abnormal, it represents that there may be an error in the currently acquired ethernet data, and at this time, it is determined whether the MVB communication state is normal at the current time. If the MVB communication state is normal, the corresponding MVB data may be determined as the target data.

S106: and assigning a value to the public array by using the target data so as to control the working system based on the public array.

After the target data is determined, the target data is assigned to the common array. The public array is used for providing data to management workers, so that each working system can be controlled by the data in the public array, and train logic control is achieved. In specific implementation, the public array may take the MVB data format as a basic storage unit, which is beneficial to the subsequent data processing process.

As a preferred implementation manner, in the embodiment of the present application, after determining whether the MVB communication state is normal by using the MVB data, if it is determined that the MVB communication state is abnormal, an emptying operation is performed on the public array. This is because when data interaction is performed through ethernet and MVB communication, there may be errors in data transmitted before an abnormal communication state occurs, and if historical data is not cleared, it is likely that erroneous data is used after communication is recovered to normal.

It can be understood that, in the embodiment of the present application, after the target data is used to assign a value to the public array, the public array may be further displayed, and specifically, the preset visual elements may be used to display the data in the public array, for example, the data of each system may be displayed in a different classification manner, so that the manager may know the operating state of the system in time.

According to the above scheme, the data processing method provided by the application comprises the following steps: acquiring Ethernet data and MVB data for representing the operating state of a working system of each connection network of a train; judging whether the Ethernet communication state is normal or not by utilizing the Ethernet data; if the Ethernet communication state is normal, determining the Ethernet data as target data; if the Ethernet communication state is abnormal, whether the MVB communication state is normal is judged by using the MVB data; if the MVB communication state is normal, determining the MVB data as target data; and assigning the public array by using the target data so as to control the working system based on the public array. As can be seen from the above, the ethernet data and MVB data of each working system are obtained, and whether the ethernet communication state is normal or not is preferentially judged, and if so, the ethernet data can be directly used; if the MVB data is abnormal, further judging whether the MVB communication state is normal, and determining whether to use the MVB data according to the judgment result. That is, preferentially use the ethernet to carry out data transmission, make full use of the advantage that ethernet transmission quantity is big, transmission rate is fast, improved data transmission speed, utilize MVB data as redundant data simultaneously, can avoid data loss, guaranteed the integrality and the accuracy of data.

The following describes and explains the process of determining whether the ethernet communication state is normal in step S102 in the data processing method disclosed in the embodiment of the present application in detail. Referring to fig. 2, specifically:

s1021: determining a first life signal corresponding to Ethernet data in the current working period;

s1022: acquiring a second vital signal corresponding to the Ethernet data in the previous working cycle;

s1023: determining whether the first vital signal is greater than the second vital signal; if yes, go to step S1024; if not, go to step S1025;

s1024: judging that the Ethernet communication state is normal;

s1025: acquiring historical Ethernet life signals corresponding to Ethernet data in a historical working period;

s1026: judging whether the historical Ethernet vital signals are not changed in a first preset number of historical working cycles or not; if so, go to step S1027;

s1027: and judging that the Ethernet communication state is abnormal.

In the embodiment of the application, the Ethernet data is acquired according to the preset work cycle. Wherein the ethernet data comprises a vital signal. After the Ethernet data of the current working period is obtained, the first life signal is determined, the Ethernet data corresponding to the previous working period of the current working period is further obtained, and the second life signal of the Ethernet data of the previous working period is determined. It can be understood that the vital signal value is continuously changed when the communication procedure is normally operated, so that whether the ethernet communication state is normal can be determined by determining whether the first vital signal is greater than the second vital signal.

It should be noted that, if it is determined that the first vital signal is not greater than the second vital signal, in this embodiment, to avoid misjudgment, instead of directly determining that the ethernet communication state is abnormal, the ethernet data in the historical operating period is acquired, and the historical ethernet vital signal corresponding to the ethernet data is determined, and if the historical ethernet vital signal does not change in the continuous historical operating period, and the number of the historical operating periods reaches the first preset number, the ethernet communication state is determined to be abnormal. Specifically, when the ethernet data in the historical operating cycles are obtained, the ethernet data in a plurality of the historical operating cycles corresponding to the first preset number may be directly obtained, and if the historical ethernet vital signals corresponding to the plurality of ethernet data are the same, it is determined that the ethernet communication state is abnormal. The first preset number may be limited according to specific situations in the implementation process, and for example, it may be set to 8, that is, if the vital signal corresponding to the ethernet data of 8 consecutive work cycles does not change, it is determined that the ethernet communication state is abnormal.

The following describes and explains the process of determining whether the MVB communication state is normal in step S104 in the data processing method disclosed in the embodiment of the present application in detail. Referring to fig. 3, specifically:

s1041: determining a third life signal in the MVB data of the current work period;

s1042: acquiring a fourth vital signal in MVB data of the previous work period;

s1043: judging whether the third vital signal and the fourth vital signal are consistent; if yes, go to step S1045; if not, the step S1044 is executed;

s1044: judging that the MVB communication state is normal;

s1045: acquiring historical MVB vital signals corresponding to MVB data in a historical work period;

s1046: judging whether the historical MVB vital signals are not changed in a second preset number of historical working cycles or not; if yes, go to step S1047;

s1047: and judging that the MVB communication state is abnormal.

In the embodiment of the present application, the MVB data includes a vital signal. Firstly, MVB data corresponding to the current working period is obtained, a third vital signal is determined, MVB data corresponding to the previous working period of the current working period is further obtained, and a fourth vital signal is determined. It should be noted that the value of the vital signal is constantly changing during the normal operation of the communication program, the maximum MVB port can only be defined as 32 bytes, which is limited by the number of ports, and the MVB data generally uses two bytes to represent the vital signal, so it is difficult to ensure that the vital signal keeps increasing.

In a specific implementation, if the third vital signal is determined to be consistent with the fourth vital signal, in order to avoid misdetermination, the MVB communication state is not directly determined to be abnormal, but the MVB data in the historical working period is acquired, and the corresponding historical MVB vital signal is determined. And if the historical MVB vital signals are not changed in the continuous second preset number of historical working cycles, judging that the MVB communication state is abnormal. The second predetermined number may be specifically limited according to specific implementation situations, for example, the second predetermined number may be set to 8, that is, if none of the MVB vital signals of 8 consecutive duty cycles has changed, the MVB communication status is determined to be abnormal.

A data processing method provided in the embodiments of the present application is described below with a specific application example. Referring to fig. 4, specifically:

firstly, the embodiment of the application defines the format of the communication protocol of Ethernet and MVB: the size of the MVB communication port is uniformly set to be 32 bytes, as shown in table 1 below, the first two bytes of data are vital signals, and the remaining bytes of data are interactive data of the port. The size of the ethernet communication port may be determined according to the actual data size, as shown in table 2 below, where the first four bytes are vital signals, and the remaining bytes of data write the same data as the MVB communication port in sequence according to the MVB communication port number. In consideration of the everyday running time of the vehicle and the running time of a TCMS (Train Control and Management System) program, the embodiment of the present application defines the size of the ethernet vital signal as 4 bytes, so as to ensure that the vital signal received in each working cycle is greater than the vital signal value in the previous working cycle in a normal communication state, and reduce the interference of other factors of the vehicle to the communication.

TABLE 1

TABLE 2

Further, the embodiment of the application defines and receives an ethernet array and an MVB array of each train system, and after data processing, the data needs to be stored in a public array for data processing. The data definition in the public array is the same as that of the MVB array, namely, the MVB data format is used as a basic storage unit, which is beneficial to the subsequent data processing process.

In specific implementation, the CCU and HMI application programs are used to periodically acquire the ethernet data and MVB data of each subsystem every period, and determine whether the communication states of the ethernet and MVB of the system are normal according to the life signals of the ethernet and MVB ports.

Specifically, the communication status of each ethernet port is determined first. If the life signal value of the Ethernet port in the current period is larger than the life signal value of the Ethernet port in the previous period, judging that the current Ethernet port is normal in communication; and if the vital signal value of the continuous 8 cycles does not change, judging that the current Ethernet port communication is abnormal. And if all the Ethernet ports are in normal communication, judging that the Ethernet communication is normal.

And if the Ethernet communication is judged to be abnormal, further determining the communication state of the MVB port. If the life signal value of the MVB port in the current period is different from the life signal value of the MVB port in the previous period, judging that the current MVB port is normal in communication; and if the vital signal values of the continuous 8 periods are not changed, judging that the communication of the current MVB port is abnormal. And if all the MVB ports are normally communicated, judging that the MVB is normally communicated.

If the Ethernet communication is judged to be normal, assigning the Ethernet data of all the Ethernet ports to the corresponding public arrays; if the Ethernet communication is abnormal and the MVB communication is normal, assigning the MVB data of all the MVB ports to the corresponding public array; and if the Ethernet communication and the MVB communication are abnormal, clearing the data in the corresponding public array.

In the embodiment of the application, by utilizing the advantages of large data transmission amount and high speed of Ethernet, the Ethernet communication mode is preferentially selected for data communication between systems, and MVB data is used as complete redundant backup, so that the data communication efficiency can be ensured, and data redundancy can be realized. In addition, through the scheme, the data processing process can be separated from the subsequent logic control and state display according to the data, so that the program structures of the central controller and the display are simplified.
