Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides an interface fault testing method, which mainly includes:
101. determining an interface which needs to be subjected to fault testing in a train control interlocking integrated product, wherein the train control interlocking integrated product comprises first safety equipment and second safety equipment, and the interface is used for realizing connection between the first safety equipment and the second safety equipment.
The train control interlocking integrated product is a signal safety control product which can simultaneously complete interlocking logic control and train operation control functions by using a set of computer system, integrates the related technology of Train Control Center (TCC) and the related technology of interlocking (CBI), and is a main product for train signal safety control.
The train control interlocking integrated product comprises a first safety device and a second safety device, and the first safety device and the second safety device are mutually standby. In order to implement the active-standby switching of the first security device and the second security device at any time, the first security device and the second security device need to perform data synchronization, and the data synchronization is implemented through the connection between the interface on the first security device and the interface on the second security device. Because the interfaces capable of realizing data synchronization directly influence the train signal safety, the interfaces required to be subjected to fault testing in the train control interlocking integration production are the interfaces capable of realizing data synchronization between the first safety equipment and the second safety equipment, and the interfaces can be a network protocol data interaction interface, a serial port protocol data interaction interface and a synchronous bus interface.
The first safety device and the second safety device have the same structure and comprise the following components: logic processing unit, communication module and power module. Interfaces are arranged in the logic processing unit and the communication module, so that the interfaces are used for realizing the connection of the first safety equipment and the second safety equipment, and the data synchronization between the first safety equipment and the second safety equipment is realized. In addition, the number of the logic processing unit, the communication unit, and the power module may be determined based on the service requirement, and this embodiment is not particularly limited.
Illustratively, as shown in fig. 2, a first safety device a and a second safety device B are included in the train control interlocking integrated product. The first security device a includes: a logic processing unit CPU1, a logic processing unit CPU2, a communication module 1, a communication module 2, a main communication module, a power supply module 1 and a power supply module 2. Likewise, the second security device B includes: a logic processing unit CPU1, a logic processing unit CPU2, a communication module 1, a communication module 2, a main communication module, a power supply module 1 and a power supply module 2. The logic processing unit CPU1, the logic processing unit CPU2, the communication module 1, and the communication module 2 are respectively provided with four network protocol data interaction interfaces N1, N2, N3, and N4, the main communication module is respectively provided with 2 serial port protocol data interaction interfaces N1, N2, and 2 network protocol data interaction interfaces C1 and C2, and the first security device a and the second security device B are respectively provided with a synchronous bus 1 interface B1 and a synchronous bus 2 interface B2. In order to implement data synchronization, the interface on the first secure device a is correspondingly connected to the interface on the second secure device B, for example, the interface N3 on the logic processing unit CPU1 in the first secure device a is connected to the interface N3 on the logic processing unit CPU1 in the second secure device B, and the interface N4 on the logic processing unit CPU1 in the first secure device a is connected to the interface N4 on the logic processing unit CPU1 in the second secure device B.
The first logical processing unit CPU1, the logical processing unit CPU2, the communication module 1, the communication module 2 in the first security device a and the second security device B shown in fig. 2 set interfaces N1, N2, N3, N4, respectively, the master communication module sets interfaces N1, N2, C1, C2, respectively, and a synchronous bus 1 interface B1 and a synchronous bus 2 interface B2. In determining the interface to be tested for faults, the interface may be selected based on specific service requirements. For example, if the failure test is required for all the interfaces for implementing data synchronization between the first safety device a and the second safety device B, all the interfaces are determined as the interfaces requiring the failure test. For example, if the current test requirement is only for a partial interface, it may be determined that the partial interface is an interface that needs to be tested for a fault, for example, the interface on the CPU and the bus interface need to be tested, and the first logical processing unit CPU1 in the first safety device a and the second safety device B, the interfaces N1, N2, N3, and N4 on the logical processing unit CPU2, and the synchronous bus 1 interface B1 and the synchronous bus 2 interface B2 are selected as the interfaces that need to be tested for a fault.
102. And carrying out fault permutation and combination on the determined interfaces to generate a plurality of fault test cases.
The process of performing fault permutation and combination on the determined interfaces is a process of listing all fault conditions that can occur to the interfaces. The process of performing fault permutation and combination on the determined interfaces may include the following three methods:
firstly, determining all master and slave role allocation conditions of a first safety device and a second safety device, respectively performing fault permutation and combination on the determined interfaces to obtain an interface open circuit under different master and slave role allocation conditions, and generating a plurality of fault test cases, wherein the interface open circuit is the interface open circuit condition.
Since the interface failure of the first security device and the second security device may generate different failure effects under different primary and secondary role allocation requests, in order to list all possible interface failures, all primary and secondary role allocation conditions of the first security device and the second security device need to be determined.
The master and standby role allocation conditions of the first safety device and the second safety device comprise the following steps: first, the first safety equipment is the main equipment, the second safety equipment is the standby equipment; in the second type, the first safety device is a standby device, and the second safety device is an active device.
After determining all the master and slave role allocation conditions of the first safety device and the second safety device, performing fault permutation and combination on the interface which is determined to be subjected to the fault test under the condition of different master and slave role allocation conditions. The fault permutation combination is a tree-structured fault permutation combination. The basis of the permutation and combination is the case of disconnection of the interface, which is the case of disconnection of the interface between the two safety devices that needs to be connected together. Illustratively, interface N3 of CPU1 of the first secure device a is connected to interface N3 of CPU1 of the second secure device B, and the disconnection is performed by disconnecting interface N3 of CPU1 of the first secure device a and disconnecting interface N3 of CPU1 of the second secure device B.
Illustratively, as shown in fig. 3, a fault is an example of a fault permutation combination of an interface open circuit, and the specific conditions of the example are as follows: the master and standby role allocation condition is as follows: the first safety device a is a main device, and the second safety device B is a standby device. The interfaces that need to be tested for faults are: interfaces N3, N4 on the first logical processing unit CPU1 and interface N3 on the logical processing unit CPU2 in the first security device a and the second security device B. As can be seen from fig. 3, it covers all cases where interface disconnection may occur, each branch forms a corresponding fault test case, and as can be seen, each fault test case includes a case where an interface is disconnected under the current active/standby allocation condition.
Illustratively, as shown in fig. 4, an example of the interface failure permutation combination is shown, and the specific case of this example is: the first safety device with the master and standby role allocation condition is as follows: the first safety device a is a standby device, and the second safety device B is an active device. The interfaces that need to be tested for faults are: interfaces N3, N4 on the first logical processing unit CPU1 and interface N3 on the logical processing unit CPU2 in the first security device a and the second security device B. As can be seen from fig. 3, it covers all cases where interface disconnection may occur, each branch forms a corresponding fault test case, and as can be seen, each fault test case includes a case where an interface is disconnected under the current active/standby allocation condition.
Secondly, determining all the master and standby role allocation conditions of the first safety equipment and the second safety equipment; and under the condition of different main and standby role distribution, respectively carrying out fault permutation and combination on the determined interfaces, wherein the fault is interface exchange, and a plurality of fault test cases are generated, wherein the interface exchange is the condition that the interface is connected to a wrong interface.
After determining all the master and slave role allocation conditions of the first safety device and the second safety device, performing fault permutation and combination on the interface which is determined to be subjected to the fault test under the condition of different master and slave role allocation conditions. The fault permutation combination is a tree-structured fault permutation combination. The basis of the permutation and combination is the interface exchange case, which is the case of exchanging the interfaces required to be connected between the two security devices. For example, a first interface on the first security device needs to be connected to a first interface on the second security device, a second interface on the first security device needs to be connected to a second interface on the second security device, after the interfaces are exchanged, the first interface on the first security device needs to be connected to the second interface on the second security device, and the second interface on the first security device needs to be connected to the first interface on the second security device. Illustratively, interface N3 on logical processing unit CPU1 in first security device a is connected to interface N3 on logical processing unit CPU1 in second security device B, interface N4 on logical processing unit CPU1 in first security device a is connected to interface N4 on logical processing unit CPU1 in second security device B, interface swapping is such that interface N3 on logical processing unit CPU1 in first security device a is connected to interface N4 on logical processing unit CPU1 in second security device B, and interface N4 on logical processing unit CPU1 in first security device a is connected to interface N3 on logical processing unit CPU1 in second security device B.
Illustratively, as shown in fig. 5, to perform an example of fault permutation and combination in which a fault is an interface exchange, the specific case of this example is: the master and standby role allocation condition is as follows: the first safety device a is a main device, and the second safety device B is a standby device. The interfaces that need to be tested for faults are: interfaces N3, N4 on the first logical processing unit CPU1 in the first secure device a and the second secure device B. As can be seen from fig. 5, it covers all the situations where interface exchange may occur, each branch forms a corresponding fault test case, and as can be seen, each fault test case includes the situation of interface exchange under the current master-slave allocation situation.
Thirdly, the two methods are used for carrying out fault permutation and combination on the interface to be tested.
103. And sorting the plurality of fault test cases based on the fault effect of each fault test case.
Because the fault effects generated by some fault test cases are the same, in order to reduce redundant fault test cases, a plurality of fault test cases need to be sorted based on the fault effects of each fault test case, and the sorting method comprises the following steps from one step to the second step:
step one, combining fault test cases with the same fault effect.
The fault test cases with the same fault effect cause waste of test cost and test time, so in order to simplify the fault test cases, the fault test cases with the same fault effect need to be merged. When the fault test cases with the same fault effect are combined, one fault test case is selected from the fault test cases with the same fault effect, the selected fault test case is reserved, and the unselected fault test cases are removed.
The following explains what is a fault test case with the same fault effect, and if the following two conditions exist, the fault test case is considered as the fault test case with the same fault effect:
first, for any two of the failure test cases: and if the interfaces required to be connected by each interface in one fault test case exist in the other fault test case and other interfaces do not exist in the other fault test case, determining that the fault effects of the two fault test cases are the same.
Illustratively, as shown in fig. 3, there are a-CPU1-N3 and a-CPU1-N4 in one fault test case, and B-CPU1-N3 and B-CPU1-N4 in another fault test case, and since a-CPU1-N3 and B-CPU1-N3 are interfaces that need to be connected correspondingly and a-CPU1-N4 and B-CPU1-N4 are interfaces that need to be connected correspondingly, it is determined that the two fault test cases are fault test cases with the same effect.
For example, as shown in fig. 5, an a-CPU1-N3 is connected to a B-CPU1-N4 in one fault test case, and an a-CPU1-N4 is connected to a B-CPU1-N3 in another fault test case, and since an a-CPU1-N3 and a B-CPU1-N3 are interfaces that need to be connected correspondingly and an a-CPU1-N4 and a B-CPU1-N4 are interfaces that need to be connected correspondingly, it is determined that the two fault test cases are fault test cases with the same effect.
Second, for any two of the failure test cases: and if each interface in one fault test case exists in the other fault test case and other interfaces do not exist in the other fault test case, determining that the fault effects of the two fault test cases are the same.
Illustratively, an A-CPU1-N3 and an A-CPU1-N4 exist in one fault test case, and an A-CPU1-N3 and an A-CPU1-N4 exist in another fault test case, and since interfaces included in the two fault test cases are the same, the two fault test cases are determined to be the fault test cases with the same effect.
And step two, reserving the fault test case with the unique fault effect.
The fault test case with the unique fault effect is a fault test case without the same fault effect in all fault test cases, so that the fault test cases are directly reserved.
Exemplarily, after the processing of the first step to the second step, the fault test case in fig. 3 is sorted, so as to obtain the fault test case shown in fig. 6.
104. And performing interface fault test according to the sorted fault test case.
The sorted fault test cases are simplified fault test cases, and the number of the fault test cases can be minimized. The sorted fault test case is the final fault test case for performing the interface fault test.
When interface fault testing is carried out, a using sequence is distributed for fault test cases, an output result of each fault test case is determined, then the first safety equipment and the second safety equipment are started according to the master-slave distribution condition of the fault test cases, and the fault test cases are sequentially executed according to the using sequence.
For example, when the fault test case corresponding to the first branch shown in fig. 6 is executed, the first safety device a is set as an active device, the second safety device B is set as a standby device, then the N3 interface on the CPU1 of the first safety device a is disconnected, that is, the channel between the interface N3 of the CPU1 of the first safety device and the interface N3 of the CPU1 of the second safety device is disconnected, and then the interface test is performed, so as to obtain the test result for the fault test case.
According to the interface fault testing method provided by the embodiment of the invention, the interface which needs to be subjected to fault testing in the train control interlocking integrated product is determined, and the determined interface can realize the interface connected between the first safety equipment and the second safety equipment in the train control interlocking integrated product. And then carrying out fault permutation and combination on the determined interfaces to generate a plurality of fault test cases, and sorting the plurality of fault test cases based on the fault effect of each fault test case. And finally, performing interface fault test according to the sorted fault test cases. Therefore, the scheme provided by the embodiment of the invention can carry out fault permutation and combination on the interfaces needing fault testing to obtain all fault test cases related to the interfaces, and then carry out sorting optimization on the fault test cases to obtain the simplest fault test case, so that the scheme can carry out comprehensive testing on the interface faults of the train control interlocking integrated product by using the most comprehensive and simplified fault test case.
