Fig. 1A is a flowchart of a testing method of a wireless communication protocol stack according to an embodiment of the present invention, where the embodiment may be adapted to deploy RCC software on actually running hardware of a CFM protocol stack and connect the hardware with a testing workstation through a corresponding interface, so that a tester writes a test case in the testing workstation to perform an abnormal model test on the CFM protocol stack. As shown in fig. 1A, the method includes:
s110, building a special test environment which comprises a train automatic protection system interface, a radio station interface, a simulation train control system and a simulation radio station.
S120, communication connection between the train automatic protection system interface and the wireless communication protocol stack test hardware and communication connection between the radio station interface and the wireless communication protocol stack test hardware are respectively established.
The wireless communication protocol stack test hardware is provided with wireless communication control (Radio Communication Control, RCC) software which is obtained by combining a CFM (communication function module Communication Functional Module) wireless communication protocol stack and an adaptation layer, and the RCC software is used for bearing the function of the CFM wireless communication protocol stack in the subset-037 protocol. There are two total types of interfaces between CFM communication protocol stack software and the outside: one type of interface is an interface with a radio station (MT), which is connected through an RS422 serial port. The information interacted on the interface comprises serial port pin signals, AT instructions and data information, and as the vehicle-mounted radio stations generally have two, the CFM communication protocol stack needs to be respectively connected with the two radio stations through two serial ports of the type; another type of interface is an interface with the SFM module in the ATP program, which connects via an SBP (Serial Bus Protocol ) bus, and transfers data as T primitives specified in SubSet-037. Correspondingly, the main functions of the RCC software are to assist the ATP in establishing a wireless communication connection with the wireless occlusion center (Radio Block Center, RBC), to process the data of the ATP and send it to the station, to be forwarded to the RBC by the station via the network, and to collect information from the station from the RBC, and to forward it to the ATP after processing. Another main function of RCC software is to control and monitor station status via AT commands. The RCC has three interfaces with the outside, one is an interface with the ATP host, and the other two are interfaces respectively connected with two radio stations. In the test environment of the invention, all interfaces of the RCC software and the outside are connected with the test workstation, and the test workstation can realize the simulation of the radio station and the ATP at the same time so as to test the RCC software.
Specifically, the CFM wireless communication protocol stack to be tested is combined with an adaptation layer (realizing the function of adapting with hardware) to form RCC software, and the RCC software is deployed on the hardware actually used by the RCC software to be tested together, so that the wireless communication protocol stack test hardware is obtained. The test workstation simultaneously realizes the simulation of the radio station and the ATP, and is connected with the wireless communication protocol stack test hardware through an ATP interface and a radio station (MT) interface.
Fig. 1B is a schematic diagram illustrating a testing principle of a testing workstation according to an embodiment of the present invention. The wireless communication protocol stack test hardware is provided with a protocol stack consisting of a CFM and an adaptation layer, and the test workstation is provided with an ATP interface and an MT interface for respectively simulating a radio station and ATP and connecting with RCC software on the wireless communication protocol stack test hardware.
S130, performing communication simulation test on the wireless communication protocol stack test hardware through the train automatic protection system interface and the radio station interface, and determining a communication test result of the CFM wireless communication protocol stack in the wireless communication protocol stack test hardware.
Specifically, corresponding test scripts are deployed on the ATP interface and the MT interface, the test environment accurately controls the data input of the interface to the RCC software by executing the test scripts to carry out communication simulation test, and the actual data output of the RCC software received by the test script checking interface is used for determining the communication test result of the CFM protocol stack. The input data to the RCC software can be the normal communication data which exists actually, so as to carry out normal communication simulation test on the RCC software; the abnormal communication data can be intentionally distorted to perform abnormal communication simulation test on the RCC software. Compared with the prior art that only three real radio stations in different states can be manufactured and ATP can not be controlled, the test environment simulates the radio stations and ATP, so that the tested CFM protocol stack does not depend on other real physical environments except the necessary wireless communication protocol stack test hardware, the test environment can simulate any protocol stack communication scene, the working conditions of the test protocol stack under different scenes can be conveniently simulated, and the difficulty of fault scene reproduction is greatly reduced.
According to the embodiment of the invention, the radio station and the ATP are simulated, so that the tested CFM protocol stack does not depend on other real physical environments except the necessary protocol stack test hardware, the test environment can simulate any protocol stack communication scene, the working conditions of the test protocol stack under different scenes can be conveniently simulated, and the difficulty of fault scene reproduction is greatly reduced.
Fig. 2 is a flowchart of a testing method of a wireless communication protocol stack according to another embodiment of the present invention, where the embodiment is optimized and improved based on the foregoing embodiment. As shown in fig. 2, the method includes:
s210, building a special test environment which comprises a train automatic protection system interface, a radio station interface, a simulation train control system and a simulation radio station.
S220, communication connection between the train automatic protection system interface and the wireless communication protocol stack test hardware and communication connection between the radio station interface and the wireless communication protocol stack test hardware are respectively established.
S230, obtaining the test cases in the table format, and converting the test cases into test scripts through a conversion tool.
The table format may be an excel format.
Specifically, the test cases are written in an excel form of the test workstation, and a tester fills in messages line by line in the excel form to generate the test cases consisting of a plurality of lines of messages in an excel file format. The written test cases can be converted into test scripts through a conversion tool so that a test engine in the test environment can be read and executed.
Optionally, the test script is composed of each row of messages determined by a functional state, where the functional state is data sent to the wireless communication control software, data sent by the wireless communication control software is checked, or a reply of modifying an AT instruction.
Specifically, in a test script consisting of a plurality of lines of messages, each line of messages corresponds to a functional state, and each functional state is executed in turn according to execution logic of the functional state. The functional status may be further differentiated as data sent to the RCC software, verification of data sent by the RCC software, or reply to modify AT instructions.
S240, sending a test T primitive to the wireless communication protocol stack test hardware through the train automatic protection system interface; acquiring a first test processing result of the test T primitive by the wireless communication protocol stack test hardware through the train automatic protection system interface and the radio station interface; and verifying the first test processing result according to the first standard processing result, and determining a communication test result of the CFM wireless communication protocol stack in the wireless communication protocol stack test hardware according to the verification result.
In the communication information structure of the CFM protocol stack, a series of primitive definitions and primitive operation functions are used to perform data linking, and a primitive of a T-CONNECT type is used as one of the primitives, and is used for message delivery, where the primitive of the T-CONNECT type is called a T primitive for short. The test T primitive can be an intentionally made abnormal T primitive or an actually existing normal T primitive, and the former can test whether the RCC software can normally process the abnormal T primitive, thereby completing the communication simulation test of the CFM protocol stack.
Specifically, the test engine interprets and executes the test script, converts the message in the test case into a test T primitive and sends the test T primitive to the RCC software. After receiving the test T primitive, the RCC software processes the test T primitive and returns the corresponding message to the test environment, and the test environment determines the test processing result of the RCC software on the test T primitive. On the ATP interface, messages sent by the RCC software to simulate ATP in the test environment are also T primitives; on the MT interface, messages sent by the RCC software to the simulation stations in the test environment are AT commands or HDLC frames. After determining the test processing result of the RCC software on the test T primitive, the test engine can read and execute the test script again to obtain a standard processing message (result) for checking the test processing result sent by the RCC software in the test case, and compare and check the test processing result with the standard processing message, if the comparison and check result is the same, the test result of the running of the RCC software is considered to be in accordance with the expected, and the communication test result is the normal running of the CFM protocol stack; otherwise, if the comparison and verification results are different, the test result of the running of the RCC software is not expected, and the communication test result is abnormal running of the protocol stack.
Optionally, before the sending the test T primitive to the wireless communication protocol stack test hardware through the automatic train protection system interface, the method further includes:
interpreting and executing a target test script on the train automatic protection system interface to convert a first message in a target test case into a T primitive, and determining the T primitive as a test T primitive; correspondingly, if the first standard processing result is a T primitive, before the verifying the first test processing result according to the first standard processing result, the method further includes: and reading and executing the second message meeting the delay processing requirement in the target test case again, converting the second message into a T primitive, and determining the T primitive as a first standard processing result.
Specifically, the interface between the RCC software and the ATP performs information interaction through a T primitive (the T primitive carries a secure layer message, and different message types have different primitive values), and the test script on the interface sequentially executes a plurality of messages according to the execution sequence in the script, and a delay processing requirement can be set between each message to adjust the execution time of the script. These messages can be divided according to functions into messages that require the test environment to send to the RCC software (i.e., test T primitives) and messages that verify that the RCC software sent to the test environment (i.e., standard processing results).
Illustratively, the user writes in excel: AAA (first row); (second row) 50ms, BBB, a target test case is generated. The conversion tool converts the target test case into a message of a target test script, the test engine reads and executes the test script, converts AAA into a test T primitive and sends the test T primitive to RCC software, and reads and executes the test script again in 50ms, and the BBB is used as a standard processing result. If the test processing result obtained by the test environment from the RCC software is not the BBB, determining that the running state of the RCC is abnormal running.
On the basis of the above embodiment, the performing, by the train automatic protection system interface and the radio station interface, a communication simulation test on the wireless communication protocol stack test hardware, and determining a communication test result of the CFM wireless communication protocol stack in the wireless communication protocol stack test hardware includes:
receiving an original AT instruction from the wireless communication protocol stack test hardware from the radio station interface, and acquiring a replying AT instruction matched with the original AT instruction from a test case or a memory space; feeding back the AT replying instruction to the wireless communication protocol stack test hardware through the radio station interface; determining a communication test result of a CFM wireless communication protocol stack in the wireless communication protocol stack test hardware according to a second test processing result of the wireless communication protocol stack test hardware on the reply AT instruction;
the reply AT instruction is a normal reply AT instruction or an abnormal reply AT instruction. The RCC software and the radio stations interact through AT instructions and HDLC frames, and two test scripts are respectively corresponding to one MT and are respectively and independently operated on the interface because of the two radio stations. The station has two modes of operation, an idle state and an on-line state. In the idle state, the interaction between the RCC and the MT is carried out through the AT instruction, the interaction mode is that the RCC actively transmits the AT instruction to the MT, and the MT transmits an AT instruction to reply the RCC after receiving the AT instruction. The MT actively sends an AT command to the RCC is disabled, i.e., in practice the MT will not actively send an AT command to the RCC. Since the interaction of the RCC software with the station is periodic and the instructions of the interaction are generally unchanged, replies to AT instructions in the test environment may be set in a default configuration file.
Specifically, under normal conditions, after the test environment is started, the content in the default configuration file is read into the memory, after the original AT instruction from the RCC software is received, the data stored in the memory is matched to find a corresponding replying AT instruction, and the replying AT instruction AT this time is generally a normal replying AT instruction; when the test environment receives the original AT instruction, the test script can be interpreted to obtain the reply AT instruction in the test case, and the reply AT instruction replaces the reply AT instruction from the configuration file and is sent to the radio station, wherein the reply AT instruction is generally an abnormal reply AT instruction. And determining a communication test result of the CFM wireless communication protocol stack according to the test processing result of the radio station. For specific subsequent flow, reference may be made to the above embodiments, and redundant description is omitted here.
On the basis of the foregoing embodiment, optionally, the performing, by the automatic train protection system interface and the radio station interface, a communication simulation test on the wireless communication protocol stack test hardware, and determining a communication test result of the CFM wireless communication protocol stack in the wireless communication protocol stack test hardware includes:
transmitting a test advanced data link control frame to the wireless communication protocol stack test hardware through the station interface; acquiring a third test processing result of the test high-level data link control frame by the wireless communication protocol stack test hardware through the train automatic protection system interface and the radio station interface; and verifying the third test processing result according to the third standard processing result, and determining a communication test result of the CFM wireless communication protocol stack in the wireless communication protocol stack test hardware according to the verification result.
Specifically, in the online state of the radio station, the data interacted between the RCC and the MT interface is a High-level data link control (HDLC) frame, and the test environment simulates the radio station to send the HDLC frame to the RCC and verify the HDLC frame sent by the RCC through the MT interface according to the state sequence of the message in the test case, and the specific process may refer to the process flow of the test T primitive in the above embodiment, which is not described too much herein.
In the embodiment of the invention, all input information of the tested RCC software can be set through the test script and the corresponding test cases, so that the simulated scene is richer, more comprehensive and finer; and because the tested RCC software only has a CFM protocol stack and does not have SFM and ATP host computer programs, when the test script is manufactured, the data information forwarded by the required CFM only needs to pay attention to the data length, and the data content can be filled in at will, thereby reducing the writing difficulty of the script.
