Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a transponder testing method, device, equipment and storage medium. Background Art

[0002] The transponder is a ground positioning device in China's train control system. It is actually installed in the middle of the rails. When a train passes by, the transponder onboard antenna installed at the bottom of the train head sends a high-energy downlink excitation RF signal to the transponder. After receiving the signal, the transponder converts it into a working power supply to start, and sends an uplink signal in the form of frequency shift keying modulation (FSK) to the transponder onboard antenna at the bottom of the train through the working circuit and the transponder transmitting antenna.

[0003] When the train passes the ground transponder, the on-board antenna and the ground transponder move horizontally relative to each other with a high degree of displacement. The distance between the train and the ground changes greatly during this movement. If you want to maintain sufficient information transmission at a higher vehicle speed and a fixed transmission speed, you need to ensure that the effective communication range of the transponder is large enough. However, an excessively large effective communication range may cause hazards such as adjacent line crosstalk.

[0004] Therefore, there is an urgent need for a transponder testing method to evaluate the effective communication range of the transponder. Summary of the invention

[0059] As described above, when a train passes a ground transponder, the onboard antenna and the ground transponder move horizontally relative to each other with a high degree of misalignment. During this movement, the distance between the train and the ground changes greatly. If you want to maintain sufficient information transmission at a higher vehicle speed and a fixed transmission speed, you need to ensure that the effective communication range of the transponder is large enough. However, an excessively large effective communication range may cause hazards such as adjacent line crosstalk.

[0060] In the related art, the transponder communication range test is based on a test of a fixed-intensity downlink excitation signal strength or a fixed-intensity uplink signal strength, but this test scheme does not comprehensively consider the transponder's receiving capability and sending capability. This scheme that evaluates the receiving capability alone can only provide the power required for the transponder and the transmitting antenna to provide the same output uplink signal power at different relative positions. The scheme that evaluates the sending capability alone can only provide the power collected by the receiving antenna at different relative positions when the transponder receives the downlink excitation signal of the same power. The actual situation is that during the vehicle-to-ground communication process, the relative position of the vehicle-mounted antenna and the ground transponder is time-varying. The evaluation scheme with a fixed single variable does not conform to the actual situation and cannot intuitively characterize its effective communication range.

[0061] The inventor of the present application has invented a transponder testing method, device, equipment and storage medium through research, which can evaluate and test the effective communication range of the transponder.

[0062] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] Device Embodiment

[0064] See also Figure 1 , which is a schematic diagram of the structure of a transponder testing device provided in an embodiment of the present application, including: a transmitting module 101, a transmitting antenna 102, a transponder to be tested 103, a receiving antenna 104 and a receiving module 105. It should be noted that the transmitting antenna 102 and the receiving antenna 104 are fixed together.

[0065] The sending module 101 is used to generate a downlink excitation signal;

[0066] A transmitting antenna 102, used for transmitting the downlink excitation signal generated by the transmitting module to the transponder to be tested;

[0067] The transponder to be tested 103 is used to generate and send an uplink signal when receiving the downlink excitation signal;

[0068] A receiving antenna 104, configured to receive the uplink signal;

[0069] The receiving module 105 is used to process the uplink signal received by the receiving antenna.

[0070] In the embodiment provided in the present application, the transponder testing device may further include a monitoring module connected to the transmitting antenna, which is used to monitor the terminal power of the transmitting antenna. That is, when the transmitting antenna sends a downlink excitation signal, the monitoring module can monitor the power of the downlink excitation signal sent by the transmitting antenna to determine whether the power of the downlink excitation signal meets the current standard. If it does not meet the standard, the transmitting module can adjust the power of the downlink excitation signal generated by it to generate a downlink excitation signal that meets the current standard.

[0071] It should be noted that the standard currently implemented is the railway standard "TB / T 3544-2018 Transponder Transmission System Test Specification", which defines the test antenna, which consists of two parts, a transmitting antenna for sending a 27.095MHz downlink excitation signal and a receiving antenna for receiving a 4.23MHz uplink signal. It is understandable that because the standard may change in the future, this application does not limit the power of the downlink excitation signal and the uplink signal.

[0072] In the embodiments provided in the present application, specific test configurations can be divided into two types, namely “standard test antenna-specific transponder” and “specific BTM-specific transponder”.

[0073] The overall configuration of the "standard test antenna-specific transponder" is substantially the same as that of the previous embodiment, which can be seen in Figure 2 , this figure is a schematic diagram of the structure of a transponder testing device for a standard antenna provided in an embodiment of the present application, including: a sending module 101, a sending antenna 102, a transponder to be tested 103, a receiving antenna 104, a receiving module 105 and a monitoring module 106.

[0074] It should be noted that the sending module and receiving module in the "standard test antenna-specific transponder" both contain multiple submodules, among which the sending module includes: an editable signal source submodule for program-controlled editing of arbitrary waves; a first attenuation submodule for reducing noise to improve the signal-to-noise ratio; a power amplification submodule for increasing signal power; a second attenuation submodule for reducing noise to prevent backflow. The receiving module includes: an inductive coupling submodule for coupling uplink signals; a low-pass filter submodule for filtering downlink excitation signals; and a first receiving acquisition instrument for collecting and storing uplink signals.

[0075] Specifically, the frequency range of the downlink excitation signal generated by the editable signal source submodule in the sending module is 1kHz to 30MHz; the bandwidth of the first attenuation submodule is not less than 30M, and the signal gain is 3dB; the bandwidth of the power amplifier submodule is not less than 30M; the bandwidth of the second attenuation submodule is also not less than 30M, and the signal gain is 3dB. The bandwidth of the inductive coupling submodule in the receiving module is not less than 30M, and the in-band coupling characteristic is linear; the cutoff frequency of the low-pass filter submodule is 10MHz, and the out-of-band attenuation is not less than 100dB; the bandwidth of the first receiving acquisition instrument is not less than 100M.

[0076] In the embodiment provided in the present application, since some BTMs are designed without output monitoring and control functions, the monitoring module 106 can be configured as a "disabled" state in the software function, and the stable output of the sending module is not adjusted by closed-loop detection control.

[0077] It should be noted that signal transmission can be performed between the sending module 101 and the sending antenna 102 via a coaxial line / RF signal; signal transmission can also be performed between the sending antenna 102 and the monitoring module 106 via a coaxial line / RF signal; signal transmission can be performed between the sending antenna 102 and the transponder to be tested 103 via a wireless near-field space / electromagnetic wave; signal transmission can also be performed between the transponder to be tested 103 and the receiving antenna 104 via a wireless near-field space / electromagnetic wave; signal transmission can be performed between the receiving antenna 104 and the receiving module 105 via a coaxial line / RF signal; signal transmission can be performed between the sending module 101 and the receiving module 105 via a coaxial line / synchronous trigger signal.

[0078] The overall configuration of "specific BTM-specific transponder" can be found in Figure 3 , this figure is a schematic diagram of the structure of a transponder testing device for a BTM antenna provided in an embodiment of the present application, including: a BTM transmitting submodule 301, a BTM transmitting antenna 302, a transponder to be tested 303, a BTM receiving sub-antenna 304, a BTM receiving module 305 and a second receiving acquisition instrument 306.

[0079] It should be noted that the configuration of "BTM test antenna-ground transponder" is to build a test environment that is more realistic, and is used to help locate and solve potential faults in the actual interconnection and interoperability of equipment from various manufacturers. Among them, "interconnection" in the railway industry specifically refers to the ability of products that have a communication relationship with each other to adapt to the product combination model of different manufacturers and brands. For example, the vehicle-mounted antenna of Company A can communicate with the ground equipment of Company A in addition to the products of other companies such as Company B and Company C.

[0080] Specifically, the BTM sending submodule 301 is used to generate a downlink excitation signal; the BTM sending antenna 302 is used to radiate and send the downlink excitation signal; the transponder to be tested 303 is used to start when receiving the downlink excitation signal, generate and send the uplink signal; the BTM receiving antenna 304 is used to receive and collect the uplink signal; the BTM receiving submodule 305 is used to process the uplink signal; the second receiving and collecting instrument 306 is used to collect and store the uplink signal processed by the BTM receiving submodule.

[0081] The present application provides a transponder test device, comprising: a sending module, a sending antenna, a receiving module, a receiving antenna and a transponder to be tested; the sending module is used to generate a downlink excitation signal; the sending antenna is used to send the downlink excitation signal generated by the sending module to the transponder to be tested; the transponder to be tested is used to generate and send an uplink signal when receiving the downlink excitation signal; the receiving antenna is used to receive the uplink signal; the receiving module is used to process the uplink signal received by the receiving antenna. The downlink excitation signal is generated by the sending module to simulate the downlink excitation radio frequency signal received by the transponder in actual application, so that the transponder can start and generate and send the uplink signal, and the uplink signal is collected by the receiving antenna and the receiving module. The transponder can be tested by analyzing the collected uplink signal, and the same antenna group structure as the actual application is adopted, that is, the sending antenna and the receiving antenna are fixed together, so that the main lobe, side lobe and crosstalk area range tested can reflect the range in the real application scenario.

[0082] Method Embodiment

[0083] See also Figure 4 , which is a schematic diagram of a transponder testing method provided in an embodiment of the present application, comprising the following steps:

[0084] S1: Use a six-axis robot to move the transponder to be tested to its initial position;

[0085] It should be noted that a six-axis robot is a form of articulated robot that can perform a wide range of applications due to its flexibility, reach and strength. A six-axis robot has six axes. Each axis is a joint that allows the robot to move in different ways. Due to its high degree of freedom, the six-axis robot is able to move the transponder to be tested to all positions within the preset range.

[0086] Specifically, the initial position can be set according to the actual test situation. For example, the position closest to the transmitting antenna can be used as the initial position to reduce the test time; or the position farthest from the transmitting antenna can be used as the initial position to obtain the test result of whether the transponder can communicate effectively at the maximum distance as soon as possible.

[0087] S2: Sending a downlink excitation signal through a sending module and a sending antenna;

[0088] Specifically, a downlink excitation signal of a specific power may be generated by a transmitting module, and the downlink excitation signal may be sent to the transponder to be tested through a transmitting antenna.

[0089] S4: collecting and storing, through a receiving module and a receiving antenna, an uplink signal sent by the transponder to be tested after receiving the downlink excitation signal;

[0090] Specifically, after receiving the downlink excitation signal, the transponder under test converts the downlink excitation signal into a working power supply to start, and sends an uplink signal in FSK form through the working circuit and the transponder transmitting antenna. The receiving module can receive the uplink signal through the receiving antenna, thereby being able to collect and store the uplink signal.

[0091] S6: Determine whether the uplink signal sent by the transponder to be tested at all preset positions has been collected, if not, execute step S8, if yes, end the test;

[0092] It should be noted that whether the uplink signals sent by the transponder to be tested at all preset positions have been collected can be determined based on the uplink signal data collected and stored by the receiving module.

[0093] S8: Use a six-axis robot to iterate the position of the transponder to be tested, and continue to execute steps S2-S6 after the position iteration.

[0094] It should be noted that before the test starts, the positions to be tested can be pre-set, for example, ten spatial points can be set. After the uplink signals emitted by the transponders to be tested at the positions of these ten spatial points are collected, the test is ended. Otherwise, a six-axis robot is used to control the transponders to be tested to the corresponding positions for testing in sequence.

[0095] In the embodiment provided in the present application, after executing step S2 and before executing step S4, the transponder testing method may further include: S3: monitoring the power of the downlink excitation signal, and when the power of the downlink excitation signal is a preset power, executing step S4, and when the power of the downlink excitation signal is not the preset power, adjusting the downlink excitation signal, and continuing to execute step S2. Through step S3, the power of the downlink excitation signal can be adjusted, so that the transponder to be tested can receive the downlink excitation signal of a specific frequency, so that the transponder to be tested can start the downlink excitation signal as a working power supply, thereby generating an uplink signal.

[0096] It should be noted that after the test is completed, the railway-related standards and the technical indicators of the transponder transmission system product design can be used as thresholds to judge whether the position corresponding to each uplink signal can communicate effectively based on the multiple uplink signals collected. The judgment standard for effective communication, that is, the judgment standard for energy large enough to be recognized, uses the judgment thresholds used in railway-related standards and actual product designs, which can be more in line with actual application scenarios and make the test results more reliable.

[0097] The present application also provides a more specific transponder testing method, see Figure 5 , which is a flow chart of another transponder testing method provided in an embodiment of the present application, including:

[0098] S501, software and hardware initialization.

[0099] Specifically, the software and hardware need to be initialized before the test begins, which can make the test results more accurate and avoid the test results being affected by previous tests.

[0100] S502, the six-axis robot controls the transponder to be tested to move to the initial position.

[0101] It should be noted that the six-axis robot has a high degree of freedom and can move the transponder to be tested to all positions within a preset range. Specifically, the initial position can be set according to the actual test situation. For example, the position closest to the transmitting antenna can be used as the initial position to reduce the test time; the position farthest from the transmitting antenna can also be used as the initial position to quickly obtain the test result of whether the transponder can communicate effectively at the maximum distance.

[0102] S503: Send a downlink excitation signal.

[0103] It should be noted that the present application can start the transponder to be tested by simulating an excitation mode when a train passes by, and therefore, a downlink excitation signal can be sent to start the transponder to be tested.

[0104] S504, determining whether the power has been adjusted to the selected power level.

[0105] Specifically, if the power has been adjusted to the selected power level, step S506 is executed; otherwise, step S505 is executed.

[0106] S505, adjusting the CW signal amplitude.

[0107] It should be noted that CW signal is the abbreviation of Continuous Wave, which refers to a continuous sinusoidal signal with a fixed output amplitude.

[0108] S506: Collect uplink signal power.

[0109] When the transponder to be tested receives a downlink excitation signal of the selected power level, it converts it into a working power source for startup, thereby being able to generate and send an uplink excitation signal, so that the uplink signal power can be collected during the test.

[0110] S507, determining whether the position iteration is complete.

[0111] When the position iteration is completed, step S508 is executed; when the position iteration is not completed, the position iteration is performed and the execution is repeated from step S503.

[0112] S508, process the data and end the test.

[0113] By analyzing the uplink signal power corresponding to all the collected positions, the test results can be obtained, and the effective communication range of the transponder can be obtained, thereby completing the evaluation test of the effective communication range of the transponder.

[0114] Specifically, the railway-related standards and technical indicators of the transponder transmission system product design can be used as thresholds, and based on the multiple uplink signals collected, it can be judged whether the position corresponding to each uplink signal can communicate effectively.

[0115] The present application provides a transponder testing method, including: using a six-axis robot to move the transponder to be tested to an initial position; S2: sending a downlink excitation signal through a sending module and a sending antenna; S4: collecting and storing the uplink signal sent by the transponder to be tested after receiving the downlink excitation signal through a receiving module and a receiving antenna; S6: judging whether the uplink signal sent by the transponder to be tested at all preset positions has been collected, if not, executing step S8, if so, ending the test; S8: using a six-axis robot to iterate the position of the transponder to be tested, and continuing to execute steps S2-S6 after the position iteration. By changing the position of the transponder by the six-axis robot, the uplink signal sent by the transponder at different positions can be collected. By collecting and processing the uplink signal sent by the transponder at different positions, it can be known that when the relative distance between the transponder and the receiving antenna is different, the power change of the uplink signal can be obtained, so that the effective communication range of the transponder can be evaluated.
