[0029] Embodiment 1

[0030] Figure 1 A flowchart of a method for testing the air interface protocol consistency of digital wireless train modulation communication provided by an embodiment of the present invention. This embodiment can be applied to the case of testing the air interface protocol consistency of digital wireless train modulation communication. The method can be executed by a device for testing the air interface protocol consistency of digital wireless train modulation communication in an embodiment of the present invention. The device can be implemented in software and / or hardware, such as Figure 1 As shown, the method specifically comprises the following steps:

[0031] S110, obtaining interaction data between the device under test and the station radio station.

[0032] In this embodiment, the interaction data includes: air interface data, and the air interface data includes: multiple air interface signaling and collection time information corresponding to each air interface signaling.

[0033] In this embodiment, the test system includes: a test device and a device under test. The device under test includes: an on-board device, which can be a cab integrated radiocommunication equipment (CIR) or an intercom device. CIR is an on-board wireless communication terminal device installed on a locomotive or EMU, which can meet various communication needs between the train driver and ground traffic control personnel (such as dispatchers, station attendants) and relevant personnel on the train (such as on-board mechanics). As an operating device directly facing the driver on a locomotive or EMU, the CIR device is related to the safe and punctual operation of the train.

[0034] In this embodiment, the air interface data packet is a data packet transmitted through radio waves in the air, and is a key resource for realizing information uploading and downloading.

[0035] In this embodiment, the acquisition time information corresponding to the air interface signaling may be the system time for collecting the air interface signaling. For example, when the air interface signaling A1 is collected at the system time t1, the acquisition time information corresponding to the air interface signaling A1 is the system time t1. In this embodiment, in wireless communication, air interface signaling refers to the signaling information transmitted on the wireless link layer (air interface). These signalings are used to establish, maintain and manage wireless connections, including control channel allocation, measurement reporting, power control, switching, etc. Air interface signaling is essential to ensure the normal operation and performance of wireless communication systems. Air interface signaling can be divided into different types, including but not limited to: Control signaling: used to control the use of wireless resources, such as switching, power control, etc. Management signaling: used to manage the establishment, modification and release of wireless connections. Data signaling: used to transmit data on wireless links. Different wireless communication standards have different air interface signaling protocols. Analysis and debugging of air interface signaling are very important for the optimization and maintenance of wireless communication systems. By analyzing air interface signaling, the operating status of the system can be understood, potential problems can be identified, and corresponding adjustments can be made.

[0036] Optionally, obtaining the interaction data between the device under test and the station radio station includes:

[0037] According to the target function and locomotive identification input by the user, air interface data corresponding to the target function is generated.

[0038] In this embodiment, the locomotive identification includes: a locomotive number and a train number. The target function may be any one of a calling function, a registration function and a deregistration function.

[0039] In this embodiment, based on the target function and locomotive identification input by the user, the method of generating air interface data corresponding to the target function can be: converting the locomotive identification into hexadecimal characters, and then adding a first character (the first character is one bit) in front of the character obtained after the conversion, and adding a second character (the second character is two bits) after the character obtained after the conversion, according to the air interface protocol and the target function, the above characters are packaged, and the packaged data is determined as the air interface data corresponding to the target function.

[0040] The air interface data corresponding to the target function is sent to the device under test.

[0041] In this embodiment, in the absence of a station radio station, the station radio station can be simulated to send the air interface data corresponding to the target function to the device under test.

[0042] Receive air interface data fed back by the device under test.

[0043] In this embodiment, the air interface data fed back by the device under test may be the fed back air interface data generated by the device under test according to the air interface data corresponding to the target function after the device under test receives the air interface data corresponding to the target function sent by the test device.

[0044] The interaction data between the device under test and the station radio station is determined according to the air interface data corresponding to the target function and the air interface data fed back by the device under test.

[0045] In this embodiment, the interaction data between the device under test and the station radio includes the air interface data sent by the device under test, the air interface data received by the device under test, the air interface data sent by the test device simulating the station radio, and the air interface data fed back by the test device simulating the station radio during multiple interactions.

[0046] In this embodiment, the method for determining the interaction data between the device under test and the station radio station according to the air interface data corresponding to the target function and the air interface data fed back by the device under test can be: according to each air interface signaling in the air interface data corresponding to the target function, and the collection time information corresponding to each air interface signaling, and each air interface signaling in the air interface data fed back by the device under test, and the collection time information corresponding to each air interface signaling, determine the interaction data between the device under test and the station radio station.

[0047] In this embodiment, the method for obtaining the interaction data between the device under test and the station radio station can also be: in the absence of a station radio station, the test device receives the air interface data sent by the device under test; and simulates the station radio station sending air interface data to the device under test; based on the air interface data sent by the device under test and the air interface data sent by the test device simulating the station radio station to the device under test, the interaction data between the device under test and the station radio station is determined.

[0048] In the prior art, if there is no station radio, the device under test cannot be tested. The technical solution provided by the embodiment of the present invention can simulate the station radio and interact with the device under test to test the device under test and obtain the test result.

[0049] Optionally, the test system further comprises: a station radio station;

[0050] Obtain the interaction data between the device under test and the station radio, including:

[0051] Receive air interface data sent by the station radio station or the device under test, where the air interface data is data transmitted between the station radio station and the device under test.

[0052] In this embodiment, when the station radio station communicates with the device under test, the test device obtains the air interface data sent by the station radio station or the device under test by monitoring the data transmitted between the station radio station and the device under test.

[0053] The air interface data sent by the station radio station and the air interface data sent by the device under test are determined as interaction data between the device under test and the station radio station.

[0054] In this embodiment, the interaction data between the device under test and the station radio station includes air interface data sent by the device under test and air interface data sent by the station radio station during multiple interaction processes.

[0055] In a specific example, Figure 2 As shown, the test equipment collects the interaction data between station radio 1 and station radio 2 and CIR1 / intercom device 1 and CIR2 / intercom device 2 through the air interface.

[0056] S120: If each air interface signaling in the air interface data satisfies a preset condition, a test result is determined according to at least one of the total number of air interface signaling in the air interface data, a field in each air interface signaling, and collection time information corresponding to each air interface signaling.

[0057] In this embodiment, according to the total number of air interface signaling in the air interface data, the fields in each air interface signaling, and at least one of the collection time information corresponding to each air interface signaling, the method for determining the test result may be: determining the test result according to the total number of air interface signaling in the air interface data and the fields in each air interface signaling. According to the total number of air interface signaling in the air interface data, the fields in each air interface signaling, and at least one of the collection time information corresponding to each air interface signaling, the method for determining the test result may also be: determining the test result according to the total number of air interface signaling in the air interface data. According to the total number of air interface signaling in the air interface data, the fields in each air interface signaling, and at least one of the collection time information corresponding to each air interface signaling, the method for determining the test result may also be: determining the test result according to the total number of air interface signaling in the air interface data and the collection time information corresponding to each air interface signaling. Based on the total number of air interface signaling in the air interface data, the fields in each air interface signaling, and at least one of the collection time information corresponding to each air interface signaling, the test result can also be determined by: determining the test result based on the fields in each air interface signaling and the collection time information corresponding to each air interface signaling.

[0058] In a specific example, if the total number of air interface signaling in the air interface data is less than the reference number corresponding to the call function, it is determined that the test result is that the call is not established.

[0059] In this embodiment, the preset condition includes at least one of the following conditions:

[0060] The check code of the air interface signaling is the same as the reference check code;

[0061] The starting character of the air interface signaling is the preset reference character.

[0062] In this embodiment, the reference check code can be calculated based on other fields in the air interface signaling except the check code. The preset reference character is related to the device under test, and the starting character of the air interface signaling corresponding to the same device under test is the same.

[0063] It should be noted that by verifying whether the check code of the air interface signaling is the same as the reference check code, the integrity of the data structure of the received interactive data can be ensured.

[0064] It should be noted that the starting character of the air interface signaling is a preset reference character in order to ensure that the received air interface data is the interaction data between the station radio and the device under test, rather than the interaction data between the station radio and other devices.

[0065] Optionally, determining the test result according to the total number of air interface signalings in the air interface data and a field in each air interface signaling includes:

[0066] Determine the function to be tested based on the fields in the air interface signaling;

[0067] If the function to be tested is a call function, and the total number of air interface signaling in the air interface data is less than the reference number of air interface signaling corresponding to the call function, it is determined that the test result is that the call is not established.

[0068] In this embodiment, the call function may be an individual call function or a group call function. The individual call function may be an individual call CIR or an individual call intercom device. The group call function may be a group call CIR or a group call intercom device, or a group call CIR and an intercom device.

[0069] In this embodiment, a correspondence table between each function of the device to be tested and the reference number of air interface signaling is pre-established, and the reference number of air interface signaling corresponding to the call function is obtained by querying the correspondence table. If the function to be tested is a call function, and the total number of air interface signaling in the air interface data is less than the reference number of air interface signaling corresponding to the call function, the test result is determined to be that the call is not established.

[0070] Optionally, the test result is determined according to the collection time information corresponding to each air interface signaling, including:

[0071] The first order is determined according to the collection time information corresponding to each air interface signaling.

[0072] In this embodiment, the manner of determining the first order according to the collection time information corresponding to each air interface signaling may be: sorting the air interface signaling in the air interface data according to the collection time information corresponding to each air interface signaling to obtain the first order.

[0073] If there is a difference between the first sequence and the reference sequence, it is determined that the test result is that the call is not established.

[0074] In this embodiment, the reference sequence is a pre-set sequence of air interface signaling. The reference sequence may be obtained by pre-establishing a correspondence table between each function of the device to be tested and the sequence of air interface signaling, obtaining the function to be tested corresponding to the air interface data, querying the correspondence table, obtaining the sequence of air interface signaling corresponding to the function to be tested, and determining the sequence of air interface signaling corresponding to the function to be tested as the reference sequence.

[0075] In this embodiment, if the first sequence and the reference sequence are different, the test result is determined to be that the call is not established. For example, if the first sequence is: air interface signaling A1, air interface signaling A2, air interface signaling A3, and the reference sequence is air interface signaling A1, air interface signaling A3, air interface signaling A2, the test result is determined to be that the call is not established.

[0076] Optionally, the test result is determined according to the fields in the air interface signaling, including:

[0077] Determine the function to be tested based on the fields in the air interface signaling.

[0078] In this embodiment, the function to be tested may be determined by identifying a field in the air interface signaling used to characterize the function to be tested.

[0079] If the function to be tested is a call function, and there is a field in the air interface signaling that does not match the reference field type, then the test result is determined to be that the call is not established.

[0080] In this embodiment, a correspondence table between the type of air interface signaling and the field type corresponding to each field in the air interface signaling is pre-established. According to the target field in the air interface signaling, the type of the air interface signaling is determined, and the correspondence table is queried according to the type of the air interface signaling to obtain the reference field type corresponding to each field in the air interface signaling. The field type corresponding to each field in the air interface signaling is obtained, and the reference field type corresponding to each field in the air interface signaling is compared with the field type corresponding to each field in the air interface signaling. If there is a field in the air interface signaling that does not match the reference field type, the test result is determined to be that the call is not established. In a specific example, if the function to be tested is a call function, and the reference field type corresponding to field 1 in the air interface signaling is B1, the reference field type corresponding to field 2 is B2, and the reference field type corresponding to field 3 is B3, the field type corresponding to field 1 in the air interface signaling is B2, the field type corresponding to field 2 is B1, and the field type corresponding to field 3 is B3, since the reference field type corresponding to field 1 and field 2 does not match the field type, the test result is determined to be that the call is not established.

[0081] If the function to be tested is a registration function, and the station name corresponding to the field in the air interface signaling is not the target station name, or the station name corresponding to the field in the air interface signaling is the target station name, and the registration status of the locomotive identification corresponding to the field in the air interface signaling is registered, then the test result is determined to be registration failure.

[0082] In this embodiment, the target station name may be obtained in the following manner: when the station radio communicates with the device under test, the target station name is the station name corresponding to the station radio. When there is no station radio, the target station name is a pre-stored station name.

[0083] In this embodiment, the method for obtaining the registration status of the locomotive identification corresponding to the field in the air interface signaling can be: query the registered locomotive list according to the locomotive identification corresponding to the field in the air interface signaling; if the locomotive identification corresponding to the field in the air interface signaling does not exist in the registered locomotive list, then determine that the registration status of the locomotive identification corresponding to the field in the air interface signaling is unregistered; if the locomotive identification corresponding to the field in the air interface signaling exists in the registered locomotive list, then determine that the registration status of the locomotive identification corresponding to the field in the air interface signaling is registered.

[0084] In this embodiment, if the function to be tested is a registration function, and the station name corresponding to the field in the air interface signaling is not the target station name, the test result is determined to be a registration failure. If the function to be tested is a registration function, the station name corresponding to the field in the air interface signaling is the target station name, and the registration status of the locomotive identification corresponding to the field in the air interface signaling is registered, the test result is determined to be a registration failure.

[0085] If the function to be tested is a deregistration function, and the station name corresponding to the field in the air interface signaling is not the target station name, or the station name corresponding to the field in the air interface signaling is the target station name, and the locomotive identification corresponding to the field in the air interface signaling does not exist in the registered locomotive list, then the test result is determined to be deregistration failure.

[0086] In this embodiment, it is determined whether there is a locomotive identification corresponding to the field in the air interface signaling in the registered locomotive list. If there is no locomotive identification corresponding to the field in the air interface signaling in the registered locomotive list, the test result is determined to be a deregistration failure.

[0087] In this embodiment, if the function to be tested is a deregistration function, and the station name corresponding to the field in the air interface signaling is not the target station name, the test result is determined to be a deregistration failure. If the function to be tested is a deregistration function, the station name corresponding to the field in the air interface signaling is the target station name, and the locomotive identifier corresponding to the field in the air interface signaling does not exist in the registered locomotive list, the test result is determined to be a deregistration failure.

[0088] Traditional automated test scripts mainly focus on system function testing and cannot verify the interactive timing of air interface signaling during device communication. At the same time, traditional automated test scripts mainly focus on capturing data signaling and often cannot analyze and judge on-site problems based on captured air interface signaling and air interface signaling reception timing. The test method provided by the embodiment of the present invention can analyze the air interface signaling sent between the station radio and the device under test, can quickly analyze the cause when the station radio and the device under test cannot establish communication, and can also perform preliminary access detection on the device under test in the absence of a station radio, thereby improving the compatibility of the test method.

[0089] In this embodiment, the test equipment includes: an information collection module and a control module. When the station radio establishes communication with the device under test, the signaling collection module will monitor all air interface signaling sent between the station radio and the device under test, and add the time field to the collected air interface signaling and send it to the control module in strict accordance with the timing. The control module parses the received air interface signaling and prints the data on the console for the tester to analyze the air interface signaling. Establishing a call between the station radio and the device under test is a standard communication process. The control module can control the signaling collection module to simulate the station radio and the device under test to establish a call. The control module selects a call function and sends the air interface signaling to the signaling collection module. After receiving the air interface signaling, the signaling collection module sends a simulated station radio to send the air interface signaling to the device under test, and then sends the collected air interface data to the control module in accordance with the timing for data analysis.

[0090] At present, the domestic railway system mainly deploys a 450MHz wireless dispatching system to realize trunking calls and data services in the "big triangle" (between train dispatchers, locomotive drivers and station attendants) and "small triangle" (between drivers, station attendants and train conductors). The railway system needs to gradually replace the current 450MHz analog train wireless dispatching system with a 400MHz digital train modulation wireless communication system. At present, the domestic railway has not yet promulgated and applied mature digital wireless train modulation system standards. The existing TB / T 2894-1998 standard, YD / T 1009-1999 standard, TB / T 1876-2011 standard and TB / T2675-2003 standard are all test standards for the 450MHz frequency band, which are not fully compatible with the digital train modulation system. In order to follow up the transformation of the 400MHz digital train modulation wireless communication system and the access of equipment to the 400MHz system, the embodiment of the present invention provides a set of air interface protocol consistency testing methods applicable to 400MHz digital wireless train modulation communication. Note: TB / T 2894-1998 standard: This standard specifies the technical requirements and test methods for 450MHz frequency band single-duplex compatible railway train wireless dispatching communication equipment. It is applicable to the production and manufacturing of station radio, locomotive radio, portable radio and dispatching switchboard equipment of the four-band single-duplex compatible train wireless dispatching communication system in the 450MHz frequency band, and is also applicable to engineering design, installation, construction and maintenance management. It cites standards such as GB12192-90 Mobile Communication FM Radio Telephone Transmitter Measurement Method and GB12193-90 Mobile Communication FM Radio Telephone Receiver Measurement Method. YD / T 1009-1999 standard: This standard specifies the technical requirements and measurement methods for 450MHz frequency band, frequency division multiple access (FDMA) wireless access system. It is applicable to the development, production and inspection of 450MHz wireless access system, and other FDMA wireless systems can also refer to it. TB / T 1876-2011 standard: This standard specifies the minimum available receiving level value of railway 450MHz train radio communication, the field strength coverage requirements and measurement methods along the railway. It is applicable to the maintenance and management of railway 450MHz train wireless dispatching communication. TB / T 2675-2003 standard: This standard involves the technical requirements and test methods of 450MHz same / different frequency simplex train wireless dispatching equipment. It includes basic requirements, main electrical performance requirements, test methods, etc., covering the specific test methods of transmitter electrical performance, receiver electrical performance, call control signal indicators, dispatching total electromechanical performance, station platform wired switching unit electrical performance, insulation resistance, insulation withstand voltage, environmental test requirements, safety requirements and reliability requirements.

[0091] In a specific example, Figure 3As shown, the test system includes: a test device (the test device includes: a signaling acquisition module and a control module) and a device under test (CIR / intercom device). The signaling acquisition module includes a data monitoring unit, a data transmission unit and a simulated data sending unit. The control module includes: a business logic unit and a display unit. The data monitoring unit of the signaling acquisition module is used to collect the air interface data sent between the station radio and the CIR / intercom device, and the air interface data includes: air interface signaling and voice information. The data monitoring unit adds the acquisition time information to the frame header of the air interface signaling according to the time sequence of the collected air interface data. The data transmission unit is used to package the air interface signaling with the acquisition time information added to the frame header and send it to the control module or receive the air interface signaling sent by the control module; the simulated data sending unit is used to test whether the CIR / intercom device can access the station radio alone without the station radio. The module can simulate the station radio to send the air interface signaling to the CIR / intercom device, and can perform a preliminary access test on the CIR / intercom device. The business logic unit of the control module is used to parse the air interface signaling and package it into a hexadecimal string, which includes multiple information. Make a legal judgment on the air interface data (judge whether each air interface signaling in the air interface data meets the preset conditions): 1. Judge the integrity (no packet loss), 2. Judge whether there is acquisition time information in the frame header. If not, it is illegal. If it exists, judge whether the starting character of the frame header is the preset reference character. If so, it is legal. 3. After the parsing is completed, the parsed field content is displayed on the interface. The interface display unit is divided into two parts, the data display part and the function selection part. The data display part is used to display the air interface signaling received by the communicating parties. After being parsed by the business logic unit, the parsing results are displayed one by one. In the absence of a station radio, select a function to test through the function selection part. The station radio and CIR / intercom equipment can realize single call, group call, registration, deregistration and other functions. After selecting a function on the display interface, the control module will send the air interface signaling to the signaling acquisition module, and the signaling acquisition module will send it to the CIR / intercom equipment.

[0092] In a specific example, the test flow of the entire system is as follows:

[0093] When the station radio station communicates with the CIR / intercom equipment, the signaling acquisition module monitors the air interface signaling sent between the station radio station and the CIR / intercom equipment, adds the acquisition time information to the data header of each air interface signaling, and then forwards the air interface signaling to the control module. After receiving the forwarded air interface signaling, the control module first determines the legality of the air interface signaling. If the air interface signaling does not meet the preset conditions, the air interface signaling is determined to be illegal, and the data is displayed as illegal on the interface, and the reason for the illegality is given. If the air interface signaling meets the preset conditions, the air interface signaling is determined to be legal, and the air interface signaling is displayed on the display interface in a time sequence according to the acquisition time information in the frame header. Maintenance personnel can perform process analysis based on the air interface signaling displayed on the interface.

[0094] In the absence of a station radio, select a call function through the control module to perform a function test on the CIR or intercom equipment. Take individual call CIR as an example. The process is as follows Figure 4As shown, after selecting the individual call CIR in the interface, the control module sends the individual call CIR control signaling to the signaling acquisition module. The signaling acquisition module simulates the station radio station initiating a paging request to the CIR according to the locomotive number and train number of the CIR in the individual call CIR control signaling, and receives the receipt data of the CIR (the CIR replies to the paging request response, the call establishment signaling). The signaling acquisition module adds the collection time information to the frame header of the signaling, and sends the signaling with the added collection time information (representing the paging response data) to the control module, and the control module parses the data; the signaling acquisition module receives the receipt data of the CIR (the CIR replies to the paging request response, the call success signaling), and the signaling acquisition module adds the collection time information to the frame header of the signaling. The signaling acquisition module receives the receipt data of CIR (CIR sends the caller number signaling), adds the collection time information to the frame header of the signaling, and sends the signaling with the collection time information (representing the caller number data) to the control module, which parses the data; the signaling acquisition module receives the receipt data of CIR (CIR sends the call status signaling), adds the collection time information to the frame header of the signaling, and sends the signaling with the collection time information (representing the call status) to the control module, which parses the data. Through the above process, the receipt data is sent to the control module in time sequence, the control module parses the data, and displays the data parsing results. The process of the control module parsing data can be: performing CRC check on the received interactive data, after the check passes, deserializing the interactive data according to the standard protocol, and judging the legitimacy of the fields of the deserialized data to judge whether the value of the field meets the expected result. If it does not meet the expected result, the error cause is displayed. If it meets the expected result, it is judged whether there is a problem with the timing of the data sent by the other end, and whether the data is missed. In addition, after parsing the data, the control module will compare the content of the data frames sent by both parties, such as judging whether the locomotive number or call number sent matches, whether the air interface signaling is valid, etc. In the case of a problem with the call, a preliminary judgment is made on the current problem and the judgment result is displayed.

[0095] After the call is established, you can also end the call. There are two ways to end the call: one is to actively end the call, and the other is to hang up the CIR / intercom device. The process of actively ending the call is: the control module sends a call end control signaling to the signaling acquisition module. After receiving the call end control signaling sent by the control module, the signaling acquisition module sends a call end signaling to the CIRR / intercom device. After sending the call end signaling to the CIRR / intercom device, the signaling acquisition module sends a call end signaling with the collection time information added to the control module. The CIR / intercom device hang-up process is as follows: the CIR / intercom device sends a call end request to the signaling acquisition module. After receiving the call end request, the signaling acquisition module adds the acquisition time information to the call end request, and sends the call end request with the added acquisition time information to the control module. After sending the call end request with the added acquisition time information to the control module, the signaling acquisition module sends a call end response to the CIR / intercom device, and after sending the call end response to the CIR / intercom device, the module adds the acquisition time information to the call end response, and sends the call end response with the added acquisition time information to the control module.

[0096] The embodiment of the present invention can quickly test the CIR / intercom equipment, can monitor and analyze the data of the currently required call functions (such as individual calls, group calls, etc.), registration functions, and deregistration functions, and can intuitively see the timing and content of sending air interface signaling, so as to facilitate rapid location of problems.

[0097] In an embodiment of the present invention, when a problem occurs in the communication between the station radio and the CIR / intercom equipment, it is possible to analyze whether there is a problem with the data transmission process based on the data transmission timing, automatically parse the collected air interface data, and provide a preliminary problem analysis result.

[0098] The technical solution of this embodiment obtains the interaction data between the device under test and the station radio station; when each air interface signaling in the air interface data meets the preset conditions, the test result is determined according to the total number of air interface signaling in the air interface data in the interaction data, the fields in each air interface signaling, and at least one of the collection time information corresponding to each air interface signaling, thereby improving the degree of automation of digital wireless train modulation communication air interface protocol consistency testing, and improving the test scope and test compatibility.
