It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
Fig. 1 is a schematic structural diagram of a wireless block center host according to an embodiment of the present invention. As shown in fig. 1, the wireless occlusion center host includes an unsafe service processing unit 110, a switching unit 120, and a network board 130.
The wireless block center host includes at least two non-secure service processing units 110, a switching unit 120 and at least two network boards 130, and in fig. 1, only the structures of a single non-secure service processing unit 110, switching unit 120 and a single network board 130 are shown for simplicity and clarity of illustration of the wireless block center host structure of the present invention.
Each unsafe service processing unit 110 is connected to each network board 130 through the switching unit, and at least one external device is connected to each network board 130.
The switching unit 120 is configured to provide each non-secure service processing unit 110 with a plurality of communication links for accessing the same network board.
The non-secure service processing unit 110 is configured to exchange data with each of the network boards through each of the communication links, and to process data sent by the network boards.
The switching unit 120 generally does not have a data processing function, and the switching unit 120 is generally only used for providing data exchange conditions for the non-secure service processing unit 110 and the network board 130, implementing a data transmission function of a secure computer platform, and providing an external ethernet communication interface. The network board 130 has a data transceiving function, the network board 130 is capable of receiving a data packet transmitted from an external device and transmitting the data packet transmitted from the external device to the non-secure service processing unit 110 via the switching unit 120, and the network board 130 is also capable of receiving a data packet transmitted from the non-secure service processing unit 110 via the switching unit 120 and transmitting the data packet transmitted from the non-secure service processing unit 110 to the external device.
Further, after the non-security service processing unit 110 receives the data packet sent by the network board 130 through the switching unit 120, the non-security service processing unit 110 also needs to maintain and manage the data packet. Specifically, the non-security service processing unit 110 may extract and parse data from the data packet, and forward the data packet to the fail-safe processing unit in the wireless block center host after the data packet is packaged according to a certain protocol; the non-secure service processing unit 110 may also send the data packet issued by the fail-safe processing unit to the network board 130 via the switching unit 120.
In the wireless block center system, the devices connected with the wireless center host can be generally computer interlocking (CBI), temporary speed limiting server (TSRS), GSM-R (GSM for Railways) interface unit, adjacent wireless block center (NRBC), CTC (Centralized Traffic Control, scheduling center) interface unit and other devices, and the wireless block center host sends corresponding control instructions to the external devices through the wireless block center host, so that the safe operation of all trains in the jurisdiction of the wireless block center host can be ensured.
The inventor considers that in the prior art, the data received or transmitted by two non-security service processing units in the wireless block center host are isolated, that is, each non-security service center can only maintain and manage the data transmitted by a communication channel directly connected with the non-security service processing unit, and cannot maintain or manage the data transmitted by a communication channel directly connected with another non-security service processing unit in the wireless block center host, however, the wireless block center host provided by the invention can enable each non-security service processing unit to maintain and manage all data transmitted between the wireless block center host and external equipment.
Fig. 2 is a schematic structural diagram of another wireless block center host according to an embodiment of the present invention. As shown in fig. 2, the wireless occlusion center host specifically includes a first fail-safe processing unit 141, a second fail-safe processing unit 142, a first non-secure service processing unit 111, a second non-secure service processing unit 112, a first network board 131, and a second network board 132; the switching unit 120 specifically includes a first switching board 121 and a second switching board 122.
The first switch board 121 is respectively connected to the first unsafe service processing unit 111, the second unsafe service processing unit 112 and the first network board 131, the second switch board 122 is respectively connected to the first unsafe service processing unit 111, the second unsafe service processing unit 112 and the second network board 132, the first fail-safe processing unit 141 is connected to the first unsafe service processing unit 111 through a communication channel, and the second fail-safe processing unit 142 is connected to the second unsafe service processing unit 112 through a communication channel.
In an alternative embodiment, the RBC functions of the first fail-safe processing unit 141, the second fail-safe processing unit 142, the first non-secure service processing unit 111, and the second non-secure service processing unit 112 may be performed by RBC application software, and the application software of each processing unit performs data interaction with hardware through an API (Application Programming Interface ).
Wherein, the first fail-safe processing unit 141 may be configured to receive and process the first data sent by the first non-secure service processing unit 111, and generate the second data and return the second data to the first non-secure service processing unit 111;
the second fail-safe processing unit 142 may be configured to receive and process the first data sent by the second non-secure service processing unit 112, and generate and return the second data to the second non-secure service processing unit 112.
In a wireless blocking center, one of the first fail-safe processing unit 141 and the second fail-safe processing unit 142 is a primary fail-safe processing unit, the other is a backup fail-safe processing unit, and similarly, one of the first non-safe service processing unit 111 and the second non-safe service processing unit 112 is a primary non-safe service processing unit, and the other is a backup non-safe service processing unit, but the primary and backup data should be the same, so that the security of the data is ensured.
Taking fig. 2 as an example, the first non-secure service processing unit 111 may be connected to the first switch board 121 and the second switch board 122 at the same time, where the first switch board 121 is connected to the first network board 131 and the second switch board 122 is connected to the second network board 132, the first non-secure service processing unit 111 may be capable of receiving and processing data transmitted by the first network board 131 and the second network board 132, and similarly, the second non-secure service processing unit 112 may also receive and process data transmitted by the first network board 131 and the second network board 132. Specifically, when two communication channels exist between each network board and each external device, as shown by reference numbers 1-8 in fig. 2, the above 8 channels exist between the wireless block center host and the external device, and in the prior art, for the first non-secure service processing unit 111, only the data of the channel 1-4 can be received, but the data of the channel 5-8 can not be received, and in the technical scheme provided by the present invention, both the first non-secure service processing unit 111 and the second non-secure service processing unit 112 can receive the data of the channel 1-8.
The advantages of this arrangement are that: when the connection between the first network board 131 and the external device is completely disconnected, or when the first network board 131 and the first switch board 121 fail, the first non-secure service processing unit 111 may still communicate data with the second network board 132 through the second switch board 122, and the second non-secure service processing unit 112 is also applicable.
It can be understood that the fail-safe processing unit bears the safe logic operation function of the instruction in the wireless blocking center host, the fail-safe processing unit is used for guaranteeing the control safety of the vehicle, the non-safe service processing unit can be generally used for executing the maintenance, management and other functions of the data packet, when the fail-safe processing unit generates the instruction, the fail-safe processing unit can package and issue the instruction, when the external device uploads the data, the non-safe service processing unit also manages the data uploaded by the external device and waits for the invoking of the fail-safe processing unit.
Further, each of the network boards 130 may include a plurality of sub-network boards;
the sub-network boards with different models are used for connecting external equipment with different models; the same type of sub-network board is used for connecting a plurality of external devices with different types, and the same sub-network board is connected with the same external device through a plurality of communication links.
Fig. 3 is a schematic structural diagram of an alternative wireless blocking center host, as shown in fig. 3, the AB machine is a fail-safe processing unit in the embodiment of the present invention, the C machine is a non-secure service processing unit in the embodiment of the present invention, and the I-system network board 1 and the I-system network board 0 are two sub-network boards of the I-system network board. Alternatively, the network board 0 may implement connection with the interface unit of the railway integrated digital mobile communication system and the dispatch centralized interface unit, and the network board 1 may implement connection with the computer interlock, the temporary speed limit server, and the adjacent wireless block center, but is not limited to the above connection device.
Further, each sub-network board may specifically include a plurality of network ports;
the same sub-network board is connected with the same external equipment through a plurality of channels constructed by a plurality of network ports.
In the previous example, taking the I-system network board 1 in fig. 3 as an example, the I-system network board 1 includes two network ports, for example, a network port 0 and a network port 1, where the I-system network board 1 is connected to two external devices through the network port 0 respectively, and is further connected to two external devices through the network port 1, so as to implement redundant channel setting for the wireless block central host.
According to the technical scheme provided by the embodiment of the invention, the exchange unit and at least two network boards are arranged in the wireless block center host, and each unsafe service processing unit is connected with each network board through the exchange unit, so that each unsafe service processing unit can maintain and manage all data transmitted between the wireless block center host and external equipment, the redundancy requirement of the wireless block center system is met, and meanwhile, the safety of the wireless block center system is ensured.
Example two
Fig. 4 is a flowchart of a communication data storage method according to a first embodiment of the present invention, where the method may be applied to determining a storage sequence number matching with an external device data packet according to a task number in the extracted external device data packet and a network board identifier of a target network card receiving the external device data packet, and storing the external device data packet according to the storage sequence number, and the method may be performed by a communication data storage device, where the communication data storage device may be implemented in a form of hardware and/or software and may be generally configured in an unsafe service processing unit in a wireless blocking center host. As shown in fig. 4, the method includes:
and S210, when the external equipment data packet is received, extracting a task number in the external equipment data packet and a network board identification of a target sub-network board for receiving the external equipment data packet.
In the example shown in fig. 2, assuming that the task number of the data packet sent by the external device 1 is m and the task number of the data packet sent by the external device 2 is m+1, the task numbers of the data packets transmitted by the channels 1, 2, 7, 8 are all m, and the task number of the data packet transmitted by the channels 3-6 is m+1.
Wherein, the network board identification includes: the target network card receives the sub-board number of the target sub-network board of the external device data packet and the channel number of the target channel of the external device data packet.
In the example shown in fig. 3, both network boards have a sub-network board 0 and a sub-network board 1, and if the I-system C machine receives 8 channels of data at the same time, the structure for storing the data may be as shown in table 1:
TABLE 1
It is easy to see that the external devices are respectively connected with the I-system network board 1 and the ii-system network board 1, so that the board numbers are 1, and the I-system network board 1 and the ii-system network board 1 are respectively provided with the network port 0 and the network port 1, so that the channel number is recorded as 0 or 1, and the task number is generated in the manner shown in the previous example.
When a structure array is used for storing data of two network boards in the I system C machine, the phenomenon of storage conflict can occur, the I system C machine cannot judge which data come from the I system network board and which data come from the II system network board, if a memory is newly opened up, the complexity of a program can be increased, and the maintenance of global variables is not facilitated.
S220, according to the task number and the network board identification, a storage sequence number matched with the external equipment data packet is determined.
In order to solve the above problems, the present invention sets a storage sequence number in advance, where the storage sequence number may be set according to the task number and the network board identifier, for example, the storage sequence number may be a number greater than the maximum value of the task number, or may be a number having a corresponding relationship with the channel number and the task number at the same time, or may use other setting methods, which is not limited specifically.
S230, storing the external device data packet according to the storage sequence number.
In an alternative embodiment, for data from a group II network board, the stored sequence number may be added to its task number, as shown in Table 2:
TABLE 2
At this time, the data packet with the task number between 0 and N is the data packet sent by the I-series network board, and the data packet with the task number greater than N is the data packet sent by the II-series network board.
According to the technical scheme of the embodiment of the invention, the storage sequence number matched with the external equipment data packet is determined according to the task number in the extracted external equipment data packet and the network board identification of the target network card for receiving the external equipment data packet, and the data packets sent by a plurality of network boards are stored in the same memory area according to the storage sequence number, so that the complexity of a program is effectively reduced, the maintenance of global variables is facilitated, and the risk of mistakenly modifying the global variables is reduced.

S330, according to the sequence number construction rule and the task number, the storage sequence number matched with the external device data packet is determined.
S340, storing the external device data packet according to the storage sequence number.
Alternatively, the external device data packets may be stored in the form of a fabric array, each external device data packet being a two-dimensional array of the fabric array.

and sending the analyzed data instructions to the first network board through a first exchange board in the wireless block center host and sending the analyzed data instructions to the second network board through a second exchange board in the wireless block center host.
