[0026] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0028] In the actual operation of the train control system CTCS2, in order to ensure the safe operation of the train, it is necessary to ensure that the on-board equipment accurately executes the track circuit information of the driver locking the carrier frequency or the transponder locking the carrier frequency, and there is no method in the prior art to test the on-board equipment's processing of the track circuit information. In view of this, the applicant in this case aims to accurately determine whether the on-board equipment accurately executes the selected track circuit information by testing the on-board equipment under different test environments. Specifically, this solution effectively fills the gap in the prior art that it is impossible to test whether the on-board equipment accurately executes the track circuit information, and accurately determines the processing of the track circuit information by the on-board equipment through carrier frequency comparison, providing a reliable test method and technical support to ensure the safe operation of the train.

[0029] To this end, the inventor of the present application has proposed a method for testing the processing of track circuit information by an on-board device. The method can be automatically executed according to predetermined steps, that is, after determining the monitoring mode of the on-board device, the carrier frequency information in the track circuit information of the test on-board device and the carrier frequency information after the on-board device responds to the track circuit information are obtained, and based on the carrier frequency information in the track circuit information and the carrier frequency information after responding to the track circuit information, it is determined whether the on-board device correctly executes the track circuit information, so as to accurately determine whether the on-board device accurately processes the track circuit information. A method for testing the processing of track circuit information by an on-board device in an embodiment of the present invention, the specific steps of which are as follows: Figure 1 As shown, including:

[0030] Step 101: Determine a vehicle-mounted device monitoring mode based on test environment information.

[0031] In the above steps, the test environment refers to the sum of various conditions and factors in which the train is tested. The test environment may include the physical environment, signal environment, and operating environment, wherein the physical environment includes line conditions, external climate conditions, and topography, etc. Line conditions may include track type (ballasted track, ballastless track), slope, curve radius, curve superelevation, turnout type, etc.; external climate conditions include temperature, humidity, air pressure, wind speed, rain and snow and other weather conditions; topography includes plains, mountainous areas, tunnels, bridges, etc. The signal environment may be track circuit signals, wireless communication signals GSM-R, and satellite positioning signals such as GPS, Beidou, etc. The operating environment may be the passenger capacity and cargo capacity of the train, etc. The on-board equipment monitoring mode is a specific working state adopted by the on-board equipment of the train under different operating scenarios and requirements. These monitoring modes are designed to ensure the safety, efficiency, and reliability of train operation, and to adapt to different operating conditions and mission requirements by real-time monitoring and control of key parameters of the train. The on-board equipment monitoring modes include full monitoring mode, partial monitoring mode, standby mode, shunting mode, visual mode, and guidance mode, etc.

[0032] In the above steps, the vehicle-mounted equipment monitoring mode is determined according to the test environment information. It can be determined according to the actual probability of the data corresponding to the test environment parameters in the test environment information, or it can be determined according to different environmental factors in the test environment information, such as evaluating the visibility and signal reception conditions under different weather conditions to determine the impact degree index. When confirming the impact degree index, it is based on a preset weighting coefficient, such as impact degree index = A*X+B*Y, where A and B are weighting coefficients, the sum of A and B is 1, X is visibility, and Y is signal reception. The impact degree index is divided into 0-10 levels, where 0-1 is standby mode, 2-3 is shunting mode, 3-4 is visual mode, 5-6 is guidance mode, 6-8 is partial monitoring mode, and 9-10 is full monitoring mode.

[0033] It is worth noting that the above steps can be to immediately enter the determination of the on-board equipment monitoring mode after the test personnel start the test system, or to dynamically adjust the on-board equipment monitoring mode according to the real-time changing test environment information during the test. For example, when the test environment changes significantly, the on-board equipment monitoring mode changes and the on-board equipment mode is determined, so as to ensure that the train can be in the test state at different test stages, and maximize the effectiveness of the test.

[0034] Step 102: Receive the track circuit information of the on-board equipment for testing, and the track circuit information is used to determine the first carrier frequency information. The track circuit information of the on-board equipment for testing may be received after step 101 or before step 101. If it is received before step 101, the on-board equipment receives the track circuit information when the tester turns on the test system; if it is received after step 101, the system enters step 102 after recognizing that the on-board equipment monitoring mode has been determined.

[0035] In this step, the on-board equipment is used to receive, process and respond to track circuit information and other signals related to train operation. The on-board equipment usually includes components such as receivers, processors, displays, etc., and its function is to ensure the safe operation and efficient control of the train. The track circuit information of the on-board equipment under test refers to various signals and data related to train operation transmitted through the track circuit system. The specific components of the track circuit information may be carrier frequency signals, modulation signals, and track voltage and current. After the on-board equipment under test receives the track circuit information, the driver or transponder selects its carrier frequency, and locks it to determine it as the first carrier frequency information, that is, the first carrier frequency information is the carrier frequency information when the driver and / or the transponder locks the carrier frequency.

[0036] Step 103: Acquire the second carrier frequency information after the on-board device responds to the track circuit information in the on-board device monitoring mode.

[0037] After the on-board device mode is determined in step 101 and the first carrier frequency information is determined in step 102, the on-board device responds to the track circuit information in step 102, that is, the on-board device processes and executes the first carrier frequency in the track circuit information to obtain the second carrier frequency information, which is the carrier frequency information currently executed by the on-board device after the on-board device responds to the first carrier frequency information.

[0038] Step 104: Based on the comparison result between the first carrier frequency information and the second carrier frequency information, determine whether the on-board equipment correctly processes the track circuit information.

[0039] After determining the first carrier frequency information in step 102 and the second carrier frequency information in step 103, it is determined whether the two are consistent. If they are consistent, it is determined that the onboard equipment correctly processes the track circuit information. The first carrier frequency information includes the width and low frequency code of the carrier frequency, and the second carrier frequency information includes the width and low frequency code of the carrier frequency.

[0040] In this step, the first carrier frequency information in the track circuit information represents the original signal characteristics of the track circuit transmitting end. In a specific on-board equipment monitoring mode, the on-board equipment processes the received track circuit information, generates the second carrier frequency information, compares the first carrier frequency information with the second carrier frequency information, and compares whether the carrier frequency information is consistent. If the comparison result shows that the two are consistent, it can be considered that the on-board equipment has correctly processed the track circuit information. On the contrary, if the comparison result shows that the carrier frequency information is inconsistent, it can be judged that the on-board equipment has not correctly processed the track circuit information, and there may be a fault or error. When it is determined that the on-board equipment has not correctly processed the track circuit information, the abnormality is recorded and an alarm message is issued. It is worth noting that the alarm message can be a direct reminder on the human-computer interaction interface, or when it is determined that the on-board equipment has not correctly processed the track circuit information, the system sends an alarm message to the alarm device, and the alarm device issues an alarm message. The alarm message can be a sound alarm or a light alarm, wherein the sound alarm can be a direct prompt that the on-board equipment has not correctly processed the track circuit information, or it can be a direct prompt result. It can be seen that the above comparison and determination process can help testers evaluate the performance and reliability of on-board equipment, discover problems in a timely manner and make adjustments and repairs to ensure the safe operation of the train.

[0041] Based on the above Figure 1It can be seen from the implementation method that the present application provides a test method for the processing of track circuit information by on-board equipment. The scheme is automatically executed according to the established steps, that is, the on-board equipment monitoring mode is determined based on the test environment information, which can make the test method adapt to different practical application scenarios and improve the flexibility and pertinence of the test; by receiving the track circuit information of the on-board equipment to determine the first carrier frequency information, and comparing it with the second carrier frequency information after the on-board equipment responds, it can accurately determine whether the on-board equipment processes the track circuit information correctly. This comparison method can effectively detect the processing capability of the on-board equipment for track circuit information under different circumstances, and ensure that the on-board equipment can accurately receive, process and respond to the track circuit information, thereby improving the safety and reliability of train operation. It can be seen that under different on-board equipment monitoring modes, the first carrier frequency information and the second carrier frequency information are automatically obtained and compared, which can accurately determine whether the on-board equipment processes the track circuit information correctly, thereby ensuring the normal operation of the train.

[0042] Furthermore, according to the above Figure 1 In the embodiment of the present invention shown in FIG. 1 , after determining the on-board device monitoring mode based on the test environment information, how to determine whether the on-board device correctly processes the track circuit information when the on-board device monitoring mode is the partial monitoring mode. The embodiment of the present invention will be described in more detail. The specific steps are as follows Figure 2 As shown, including:

[0043] Before formally introducing how to determine whether the on-board device correctly processes the track circuit information when the on-board device monitoring mode is the partial monitoring mode, this embodiment also introduces how to determine the on-board device monitoring mode based on the test environment information, as follows:

[0044] The on-board equipment monitoring mode is a specific working state adopted by the on-board equipment in different operating scenarios and requirements, including full monitoring mode, partial monitoring mode, standby mode, shunting mode, visual mode and guidance mode, etc. In order to ensure that the on-board equipment can be accurately tested in different modes, the on-board equipment monitoring mode is determined according to the working state of the on-board equipment. The corresponding data of the test environment parameters in the test environment information of the on-board equipment are obtained, and the probability of missing the parameter value of the corresponding data of the test environment parameters is calculated. If the missing probability is greater than or equal to the first preset probability, the on-board equipment mode of the current on-board equipment is determined to be a partial monitoring mode, wherein the first preset probability is the probability of allowing the missing of the corresponding data of the test environment parameters. When the corresponding data of the test environment parameters in the test environment information of the on-board equipment are not missing, the on-board equipment mode of the current on-board equipment is determined to be a full monitoring mode. In the event of a station signal equipment failure or other special circumstances, if the test environment information contains guidance information from the bottom guidance equipment, the on-board equipment monitoring mode is determined to be the guidance mode; when the ground signal equipment cannot work normally and the train speed is low, and the road condition information ahead obtained in the test environment information requires manual observation, the on-board equipment monitoring mode is determined to be the visual mode; when the test environment information identifies that the train is in a station or a special shunting area, the on-board equipment monitoring mode is determined to be the shunting mode; when the test environment information identifies that the train can unconditionally output maximum common braking and can maintain this maximum common braking, the on-board equipment monitoring mode is determined to be the standby mode.

[0045] It is worth noting that when the on-board device monitoring mode is standby mode, the on-board device only processes the driver's locked carrier frequency information. When the on-board device monitoring mode is partial monitoring mode, the on-board device not only processes the driver's locked carrier frequency information, but also processes the transponder locked carrier frequency information, but when the transponder locked carrier frequency information and the driver locked carrier frequency information exist at the same time, only the transponder locked carrier frequency information is processed. When the on-board device monitoring mode is visual mode, the on-board device not only processes the driver's locked carrier frequency information, but also processes the transponder locked carrier frequency information, but when the transponder locked carrier frequency information and the driver locked carrier frequency information exist at the same time, only the transponder locked carrier frequency information is processed. When the on-board device monitoring mode is guidance mode, the on-board device not only processes the driver's locked carrier frequency information, but also processes the transponder locked carrier frequency information, but when the transponder locked carrier frequency information and the driver locked carrier frequency information exist at the same time, only the transponder locked carrier frequency information is processed. When the on-board device monitoring mode is shunting mode, the on-board device only processes the driver's locked carrier frequency information. When the on-board device monitoring mode is the full monitoring mode, the on-board device only processes the transponder locked carrier frequency information.

[0046] After the on-board device monitoring mode of the on-board device is clarified, this embodiment gives a more detailed judgment on whether the on-board device correctly processes the track circuit information. Now, the on-board device monitoring mode is a partial monitoring mode as an example for explanation, as follows:

[0047] Step 201: Determine that the vehicle-mounted equipment monitoring mode is a partial monitoring mode.

[0048] Step 202: The first carrier frequency information is the driver locked carrier frequency information or the transponder locked carrier frequency information.

[0049] Step 203: Determine whether the first carrier frequency information is the driver-locked carrier frequency information.

[0050] After the on-board device receives the first carrier frequency information of step 202 in the track circuit information, it determines whether the first carrier frequency information is transponder locked carrier frequency information or driver locked carrier frequency information according to the carrier frequency signal source identifier, wherein the carrier frequency signal source identifier is a driver locked signal source and a transponder locked signal source. If the carrier frequency signal source identifier is a driver locked signal source, the first carrier frequency information is the driver locked carrier frequency information. If the carrier frequency signal source identifier is a transponder locked signal source, it is the transponder locked carrier frequency information.

[0051] Step 204: Determine whether the first carrier frequency information is consistent with the second carrier frequency information.

[0052] If step 203 determines that the on-board equipment determines that the first carrier frequency information is the driver-locked carrier frequency information, then the first carrier frequency type and the first low-frequency code in the driver-locked carrier frequency information and the second carrier frequency type and the second low-frequency code in the second carrier frequency information are obtained, wherein the first carrier frequency type can be an uplink carrier frequency or a downlink carrier frequency, the second carrier frequency type can be an uplink carrier frequency or a downlink carrier frequency, the first low-frequency code and the second low-frequency code are a signal used to transmit control information to the train, such as a certain low-frequency code may indicate that the train is allowed to run at a certain speed or that the front route is open, etc., which are not limited here. The first low-frequency code and the second low-frequency code can be different frequencies such as 10.3Hz, 11.4Hz, 12.5Hz, 13.6Hz...26.8Hz, 27.9Hz, 29Hz, etc. After determining the first carrier frequency type, the first low-frequency code, the second carrier type and the second low-frequency code, respectively compare whether the first carrier frequency type and the second carrier type, the first low-frequency code and the second low-frequency code are consistent.

[0053] Step 207: Determine whether the on-board equipment correctly executes the track circuit information.

[0054] If step 204 determines that the first carrier frequency type is consistent with the second carrier frequency type and the first low frequency code is consistent with the second low frequency code, it is determined that the onboard device correctly processes the track circuit information.

[0055] Step 208: Determine that the onboard equipment does not correctly execute the track circuit information.

[0056] If step 204 determines that the first carrier frequency type is inconsistent with the second carrier frequency type or the first low frequency code is inconsistent with the second low frequency code, it is determined that the on-board device has not correctly processed the track circuit information. Specifically, it is determined whether the carrier frequency types of the first carrier frequency information and the second carrier frequency information are the same. If they are the same, it is determined that the on-board device correctly processes the track circuit information. At this time, the first low frequency code and the second low frequency code are further compared. When the second low frequency code exists, if the first low frequency code is consistent with the second low frequency code, it is determined that the on-board device correctly processes the track circuit information, which is a valid judgment. If the first low frequency code and the second low frequency code are inconsistent, it is determined that the on-board device correctly processes the track circuit information, which is an invalid judgment. If when determining the carrier frequency type of the carrier frequency information, it is determined that the first carrier frequency type and the second carrier frequency type are inconsistent, the state of the second low frequency code is determined. If the second low frequency code is in a codeless state, it is determined that the on-board device correctly processes the track circuit information, which is a valid judgment. If the second low-frequency code is in a coded state, it is determined that the on-board device has not correctly processed the track circuit information. At this time, the recording module records the abnormality and determines that the on-board device has not correctly processed the track circuit information as a valid judgment.

[0057] Step 205: Determine whether the vehicle-mounted device discards the transponder locked carrier frequency information.

[0058] If step 203 determines that the vehicle-mounted device determines that the first carrier frequency information is the transponder locked carrier frequency information, it is determined whether the vehicle-mounted device discards the transponder locked carrier frequency information according to the record information of the test record module.

[0059] Step 208: Determine that the onboard equipment does not correctly execute the track circuit information.

[0060] If the on-board device discards the transponder locked carrier frequency information, it is determined that the on-board device has not correctly processed the track circuit information, and an alarm message is issued at this time, and the test recording module records the test abnormality.

[0061] Step 206: Determine whether the first carrier frequency information is consistent with the second carrier frequency information.

[0062] If it is determined based on the recorded information of the test recording module that the on-board device has not discarded the transponder locked carrier frequency information, the first carrier frequency information and the second carrier frequency information are compared. Specifically, the width of the carrier frequency information or the low-frequency code in the carrier frequency information can be compared. For example, it is determined whether the widths of the first carrier frequency information and the second carrier frequency information are the same. If they are the same, it is determined that the on-board device correctly processes the track circuit information. At this time, the first low-frequency code and the second low-frequency code are further compared.

[0063] Step 208: Determine that the onboard equipment does not correctly execute the track circuit information.

[0064] If the first low frequency code is consistent with the second low frequency code, it is determined that the on-board device correctly processes the track circuit information, which is a valid judgment. If the first low frequency code is inconsistent with the second low frequency code, it is determined that the on-board device correctly processes the track circuit information, which is an invalid judgment.

[0065] Step 207: Determine whether the on-board equipment correctly executes the track circuit information.

[0066] When the widths of the first carrier frequency information and the second carrier frequency information are different, it is determined whether the second low frequency code exists. If the second low frequency code is without code, it is determined that the on-board device correctly processes the track circuit information as a valid judgment. If the second low frequency code is with code, it is determined that the on-board device does not correctly process the track circuit information. At this time, the recording module records this abnormality and determines that the on-board device does not correctly process the track circuit information as a valid judgment.

[0067] The above embodiments are now described by examples:

[0068] Example 1: It is known that the first carrier frequency information in the track circuit information is the driver locked carrier frequency information, wherein the driver locked carrier frequency is the uplink carrier frequency, the carrier frequency width of the uplink carrier frequency is 1700HZ, the low frequency code of the uplink carrier frequency is 20.1HZ, the carrier frequency type of the current train is the uplink carrier frequency, the carrier frequency width of the current uplink carrier frequency is 1700HZ, and the low frequency code of the uplink carrier frequency is 19.1HZ.

[0069] According to the above known conditions, the carrier frequency information locked by the driver is the first carrier frequency information in the track circuit information received by the on-board equipment, the uplink carrier frequency is the first carrier frequency type, the low frequency code 20.1HZ is the first low frequency code, and the carrier frequency type of the current train is the second carrier frequency type, that is, the information after the on-board equipment responds to the first carrier frequency information, and the low frequency code 19.1HZ is the second low frequency code. Compare the first and second carrier frequency types, and determine that the carrier frequency types are the same and are both uplink carrier frequencies, and determine that the on-board equipment correctly processes the track circuit information. In order to ensure the effectiveness of determining that the on-board equipment correctly processes the track circuit information, it is necessary to further determine whether the first low frequency code and the second low frequency code are the same. If they are the same, it is confirmed that the on-board equipment correctly processes the track circuit information. If they are not the same, the low frequency codes are different at this time, and it is determined that the on-board equipment correctly processes the track circuit information. Before confirming the effectiveness of determining that the on-board equipment correctly processes the track circuit information, the carrier frequency width under the carrier frequency type can also be judged. If the carrier frequency width is the same, at this time, the carrier frequency widths of both are 1700HZ, and it is determined that the on-board equipment correctly processes the track circuit information. If in the above-mentioned known conditions, when the carrier frequency type of the current train is a downlink carrier frequency and the second low-frequency code is no code, it is determined that the on-board equipment correctly processes the track circuit information, and this determination that the on-board equipment correctly processes the track circuit information is valid. If in the above-mentioned known conditions, when the carrier frequency type of the current train is a downlink carrier frequency, it is determined that the first carrier frequency type is inconsistent with the second carrier frequency type, and it is determined that the on-board equipment does not correctly process the track circuit information. In order to ensure the effectiveness of determining whether the on-board equipment correctly processes the track circuit information, it is also necessary to verify the low-frequency code. When the current low-frequency code of the current train is in a no-code state, it is determined that the on-board equipment does not correctly process the track circuit information, and the determination that the on-board equipment does not correctly process the track circuit information is valid. When the current low-frequency code of the current train is in a no-code state, it is determined that the on-board equipment correctly processes the track circuit information, and the determination that the on-board equipment correctly processes the track circuit information is valid.

[0070] Example 2: It is known that the first carrier frequency information in the track circuit information is the driver locked carrier frequency information, wherein the driver locked carrier frequency is the uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low frequency code of the uplink carrier frequency is 20.1HZ. The carrier frequency type of the current train is the uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low frequency code of the uplink carrier frequency is 20.1HZ.

[0071] According to the above known conditions, it can be known that the driver locks the carrier frequency information as the first carrier frequency information in the track circuit information received by the on-board equipment, the uplink carrier frequency is the first carrier frequency type, the low-frequency code 20.1HZ is the first low-frequency code, and the carrier frequency type of the current train is the second carrier frequency type, that is, the information after the on-board equipment responds to the first carrier frequency information, the low-frequency code 20.1HZ is the second low-frequency code, and the first and second carrier frequency types are compared to determine that the carrier frequency types are the same and are both uplink carrier frequencies. Then, the carrier frequency width under the carrier frequency type is judged, and it is found that the carrier frequency width is 1700HZ. Then, the low-frequency codes are compared, and it is found that the first low-frequency code is the same as the second low-frequency code, both of which are 20.1HZ. It is determined that the on-board equipment correctly processes the track circuit information and the determination that the on-board equipment correctly processes the track circuit information is a valid judgment.

[0072] Example 3: It is known that the first carrier frequency information in the track circuit information is the transponder locked carrier frequency information, wherein the transponder locked carrier frequency is the uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low frequency code of the uplink carrier frequency is 20.1HZ. There is a record in the test record module that the on-board equipment has not discarded the transponder locked carrier frequency information. The carrier frequency type of the current train is the uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low frequency code of the uplink carrier frequency is 20.1HZ.

[0073] According to the above conditions, there is a record in the test record module that the on-board device has not discarded the transponder locked carrier frequency information, indicating that the on-board device has executed the transponder locked carrier frequency information. Then, the first carrier frequency information and the second carrier frequency information are compared, such as comparing the width of the carrier frequency information or the low-frequency code in the carrier frequency information. Specifically, the transponder locked carrier frequency information is the first carrier frequency information in the track circuit information received by the on-board device, the uplink carrier frequency is the first carrier frequency type, the low-frequency code 20.1HZ is the first low-frequency code, and the carrier frequency type of the current train is the second carrier frequency type. Type, that is, the information after the on-board equipment responds to the first carrier frequency information, the low-frequency code 20.1HZ is the second low-frequency code, and the first and second carrier frequency types are compared to determine that the carrier frequency types are the same and are both uplink carrier frequencies. Then the carrier frequency width under the carrier frequency type is judged, and it is found that the carrier frequency width is 1700HZ. Then the low-frequency code is compared, and it is found that the first low-frequency code is the same as the second low-frequency code, both are 20.1HZ, and it is determined that the on-board equipment correctly processes the track circuit information and the judgment that the on-board equipment correctly processes the track circuit information is a valid judgment. If, under the above known conditions, the recorded information of the test recording module records that the on-board equipment discards the transponder locked carrier frequency information, it is determined that the on-board equipment did not correctly process the track circuit information. At this time, an alarm message is issued, and the test recording module records the abnormality of this test. If in the above known conditions, the carrier frequency type of the current train is an uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low-frequency code in the uplink carrier frequency is 18.0HZ, then the first low-frequency code and the second low-frequency code are different. At this time, the judgment that the on-board equipment correctly processes the track circuit information is a valid judgment, that is, it is determined that the on-board equipment does not correctly process the track circuit information. If in the above known conditions, the carrier frequency type of the current train is a downlink carrier frequency, and the low-frequency code in the uplink carrier frequency is in an uncoded state, it is determined that the on-board equipment correctly processes the track circuit information and the judgment that the on-board equipment correctly processes the track circuit information is a valid judgment. If in the above known conditions, the carrier frequency type of the current train is a downlink carrier frequency, and the low-frequency code in the uplink carrier frequency is in a coded state, it is determined that the on-board equipment does not correctly process the track circuit information and the judgment that the on-board equipment does not correctly process the track circuit information is a valid judgment.

[0074] Based on the above Figure 2It can be seen from the implementation method that the present application provides a test method for the on-board equipment to process track circuit information. The scheme is automatically executed according to the established steps, that is, when the on-board equipment monitoring mode is the partial monitoring mode, when the first carrier frequency information is the driver locked carrier frequency information or the transponder locked carrier frequency information, the first carrier frequency information is determined by receiving the track circuit information of the on-board equipment, and compared with the second carrier frequency information after the on-board equipment responds, it can accurately determine whether the on-board equipment processes the driver locked carrier frequency information or the transponder locked carrier frequency information correctly. This comparison method can effectively detect the processing capability of the on-board equipment for track circuit information in the partial monitoring mode, ensuring that the on-board equipment can accurately receive, process and respond to the track circuit information, thereby improving the safety and reliability of train operation.

[0075] Furthermore, according to the above Figure 1 In the embodiment of the present invention shown in FIG. 1 , after determining the on-board device monitoring mode based on the test environment information, how to determine whether the on-board device correctly processes the track circuit information when the on-board device monitoring mode is in the partial monitoring mode. Another embodiment of the present invention will be described in more detail. Now, the on-board device monitoring mode is in the partial monitoring mode as an example. The specific steps are as follows: Figure 3 As shown, including:

[0076] Step 301: Determine that the vehicle-mounted device monitoring mode is a partial monitoring mode.

[0077] Step 302: The first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information.

[0078] Step 303 determines whether the first timestamp is earlier than the second timestamp.

[0079] When step 302 determines that the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information, first determine the reception time of the driver locked carrier frequency information and the transponder locked carrier frequency information according to the first timestamp and the second timestamp in the recording module, the first timestamp is the timestamp when the vehicle-mounted device receives the driver locked carrier frequency information, and the second timestamp is the timestamp when the vehicle-mounted device receives the transponder locked carrier frequency information. If the first timestamp is earlier than the second timestamp, it is determined that the vehicle-mounted device first executes the driver locked carrier frequency information and then executes the transponder locked carrier frequency information, and executes the step of determining the first carrier frequency type according to the driver locked carrier frequency information. If the first timestamp is equal to or later than the second timestamp, it is determined that the vehicle-mounted device executes the transponder locked carrier frequency information but does not execute the driver locked carrier frequency information, and executes the step of determining whether the vehicle-mounted device discards the transponder locked carrier frequency information.

[0080] Step 304: Compare the first carrier frequency information and the second carrier frequency information to see if they are consistent.

[0081] When step 303 determines that the first timestamp of the driver's locked carrier frequency information is earlier than the second timestamp, and determines that the transponder locked carrier frequency information is later than the driver locked carrier frequency information, it should first be determined whether the driver locked carrier frequency information is correctly processed, and the judgment method is the same as the method of judging whether the vehicle-mounted device correctly executes the driver locked carrier frequency information in case 1. If it is judged that the vehicle-mounted device correctly executes the driver locked carrier frequency information, the transponder locked carrier frequency information is further executed, wherein the judgment method of determining whether the vehicle-mounted device correctly executes the transponder locked carrier frequency information is the same as the method of judging whether the vehicle-mounted device correctly executes the transponder locked carrier frequency information in case 1. If it is judged that the vehicle-mounted device does not correctly execute the driver locked carrier frequency information, it is determined that the vehicle-mounted device does not correctly execute the track circuit information, and the recording module records this event.

[0082] Step 305 compares the third low frequency code and the fourth low frequency code to see if they are consistent.

[0083] When step 303 determines that the first timestamp is equal to or later than the second timestamp, it is determined that the transponder locked carrier frequency information and the driver locked carrier frequency information exist at the same time or the transponder locked carrier frequency information is earlier than the driver locked carrier frequency information, then it is determined that the vehicle-mounted device executes the transponder locked carrier frequency information but does not execute the driver locked carrier frequency information. At this time, the method of judging whether the vehicle-mounted device correctly executes the transponder locked carrier frequency information is the same as the method of judging whether the transponder locked carrier frequency is correctly executed when the first carrier frequency is the transponder locked carrier frequency information in the partial monitoring mode. After judging that the vehicle-mounted device correctly executes the transponder locked carrier frequency, the third low-frequency code and the fourth low-frequency code are obtained at this time, the third low-frequency code is the low-frequency code after the vehicle-mounted device correctly executes the transponder locked carrier frequency information, and the fourth low-frequency code is the low-frequency code after the vehicle-mounted device correctly executes the transponder locked carrier frequency information; and it is judged and compared whether the third low-frequency code is consistent with the fourth low-frequency code.

[0084] Step 306: Determine whether the onboard equipment does not correctly process the track circuit information.

[0085] When step 305 determines that there is inconsistency between the third low-frequency code and the fourth low-frequency code, it means that the on-board device has processed the driver's locked carrier frequency information. In the partial monitoring mode, when the on-board device receives the transponder locked carrier frequency information earlier than the driver locked carrier frequency information, the on-board device only processes the transponder locked carrier frequency information. Therefore, when there is inconsistency between the third low-frequency code and the fourth low-frequency code, it is determined that the on-board device has invalidly processed the track circuit information correctly, that is, it is determined that the on-board device has not correctly processed the track circuit information, and an alarm message is issued.

[0086] Step 307: Determine whether the onboard equipment processes the track circuit information correctly.

[0087] When step 305 determines that the third low frequency code is consistent with the fourth low frequency code, in the partial monitoring mode, when the on-board device receives the transponder locked carrier frequency information earlier than the driver locked carrier frequency information, the on-board device only processes the transponder locked carrier frequency information. When the third low frequency code is consistent with the fourth low frequency code, it means that the on-board device has not processed the driver locked carrier frequency information. At this time, it is determined that the on-board device correctly processes the track circuit information.

[0088] The above embodiments are now described by examples:

[0089] Example 1: It is known that the first carrier frequency information is the driver-locked carrier frequency information and the transponder-locked carrier frequency information. The test recording module records that the first timestamp of the driver-locked carrier frequency information is earlier than the second timestamp of the transponder-locked carrier frequency information, and the test recording module records that the on-board equipment has correctly executed the driver-locked carrier frequency information. The carrier frequency width of the transponder-locked carrier frequency is 1700HZ, and there is a low-frequency code of 20.1HZ. The carrier frequency width of the current carrier frequency of the train is 1700HZ, and the low-frequency code is 20.1HZ.

[0090] According to the above conditions, it can be known that the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information, and the on-board equipment has correctly executed the driver locked carrier frequency information. At this time, it is judged whether the on-board equipment has correctly executed the transponder locked carrier frequency information. First, the carrier frequency width of the transponder locked carrier frequency is compared with the carrier frequency width of the train's current carrier frequency. At this time, the carrier frequency widths of the two are both 1700HZ, and it is determined that the on-board equipment has correctly executed the transponder locked carrier frequency information. To ensure the validity of the judgment, the low-frequency code is further compared, and it is found that the low-frequency codes of the two are also the same, both 20.1HZ. At this time, it is determined that the on-board equipment has correctly executed the transponder locked carrier frequency information. The judgment is valid, that is, it is determined that the on-board equipment has correctly executed the track circuit information. If under the above conditions, the carrier frequency width of the train's current carrier frequency is 2000HZ, and the low-frequency code of the current carrier frequency is in a no-code state, then it is determined that the on-board equipment correctly executes the transponder to lock the carrier frequency information. If the low-frequency code of the current carrier frequency is in a no-code state, then the judgment that the on-board equipment correctly executes the transponder to lock the carrier frequency information is invalid. At this time, it is determined that the on-board equipment does not correctly execute the transponder to lock the carrier frequency information.

[0091] Example 2: It is known that the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information, wherein the transponder locked carrier frequency is the uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low frequency code of the uplink carrier frequency is 20.1HZ; the driver locked carrier frequency is the uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low frequency code of the uplink carrier frequency is 17.1HZ; and the timestamps of the on-board equipment receiving the transponder locked carrier frequency information and the driver locked carrier frequency information are the same; the test recording module records that the on-board equipment has not discarded the transponder locked carrier frequency, and the carrier frequency type of the current train is the uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low frequency code of the uplink carrier frequency is 19.1HZ.

[0092] According to the above discussion, in the partial monitoring mode, when the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information, if the timestamps of the on-board device receiving the transponder locked carrier frequency information and receiving the driver locked carrier frequency information are the same time or the timestamp of the on-board device receiving the transponder locked carrier frequency information is earlier than the timestamp of the driver locked carrier frequency information, then the on-board device only processes the transponder locked carrier frequency. At this time, first determine whether the on-board device discards the transponder locked carrier frequency according to the test recording module. According to the above known conditions, it can be known that the on-board device has not discarded the transponder locked carrier frequency information, indicating that the vehicle has executed the transponder locked carrier frequency information, and further compare the first carrier frequency information and the second carrier frequency information, such as comparing the width of the carrier frequency information, where the transponder locked carrier frequency information is received by the on-board device. The first carrier frequency information in the track circuit information, the uplink carrier frequency is the first carrier frequency type, the first low-frequency code is 20.1HZ, and the carrier frequency type of the current train is the second carrier frequency type, that is, the second low-frequency code is 20.1HZ after the on-board equipment responds to the transponder locked carrier frequency information in the first carrier frequency information. Compare the first and second carrier frequency types, and determine that the carrier frequency types are the same and are both uplink carrier frequencies. Then, the carrier frequency width under the carrier frequency type is judged, and it is found that the carrier frequency width is 1700HZ, which determines that the on-board equipment correctly processes the track circuit information. To ensure the validity of its judgment, the low-frequency code is compared, and it is found that the first low-frequency code is different from the second low-frequency code. At this time, the judgment that the on-board equipment correctly processes the track circuit information is invalid. At this time, it is determined that the on-board equipment does not correctly process the track circuit information. If, under the above known conditions, the recorded information of the test recording module records that the on-board equipment discards the transponder locked carrier frequency information, it is determined that the on-board equipment does not correctly process the track circuit information. At this time, an alarm message is issued, and the test recording module records the abnormality of this test. If in the above known conditions, the carrier frequency type of the current train is an uplink carrier frequency, and the carrier frequency width of the uplink carrier frequency is 1700HZ, and the low-frequency code in the uplink carrier frequency is 20.1HZ, then the first low-frequency code and the second low-frequency code are the same, and at this time, the judgment that the on-board equipment correctly processes the track circuit information is a valid judgment, that is, it is determined that the on-board equipment correctly processes the track circuit information. If in the above known conditions, the carrier frequency type of the current train is a downlink carrier frequency, and the low-frequency code in the uplink carrier frequency is in an uncoded state, it is determined that the on-board equipment correctly processes the track circuit information and the judgment that the on-board equipment correctly processes the track circuit information is a valid judgment. If in the above known conditions, the carrier frequency type of the current train is a downlink carrier frequency, and the low-frequency code in the uplink carrier frequency is in a coded state, the judgment that the on-board equipment does not correctly process the track circuit information is a valid judgment, that is, it is determined that the on-board equipment does not correctly process the track circuit information.

[0093] Based on the above Figure 3It can be seen from the implementation method that the present application provides a test method for the on-board equipment to process the track circuit information. The scheme is automatically executed according to the established steps, that is, when the on-board equipment monitoring mode is the partial monitoring mode, when the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information, after determining the first carrier frequency information by receiving the track circuit information of the on-board equipment, first compare the sequence of the first timestamp and the second timestamp, and compare the first carrier frequency information with the second carrier frequency information after the on-board equipment responds according to the established judgment rules, which can accurately determine whether the on-board equipment processes the driver locked carrier frequency information and the transponder locked carrier frequency information correctly. This comparison method can effectively detect the processing capability of the on-board equipment to the track circuit information in the partial monitoring mode, ensure that the on-board equipment can accurately receive, process and respond to the track circuit information, thereby improving the safety and reliability of train operation.

[0094] Furthermore, the present application also provides another embodiment, specifically, when the on-board device monitoring mode is the full monitoring mode, and the first carrier frequency information is the driver locked carrier frequency information and / or the transponder locked carrier frequency information, the specific judgment of whether the on-board device correctly processes the track circuit information is as follows:

[0095] When the on-board device monitoring mode is the full monitoring mode, and the first carrier frequency information is the driver locked carrier frequency information or the transponder locked carrier frequency information, it is determined whether the first carrier frequency information is the driver locked carrier frequency or the transponder locked carrier frequency information according to the carrier frequency signal source identifier. If the first carrier frequency information is the transponder carrier frequency information, the step of judging whether the on-board device correctly executes the transponder carrier frequency information is the same as the step of judging whether the on-board device correctly executes the transponder carrier frequency information when the first carrier frequency information is the transponder carrier frequency information in the partial monitoring mode. If the first carrier frequency information is determined to be the driver locked carrier frequency information according to the carrier frequency signal source identifier, the low frequency code of the current train and the low frequency code of the driver locked carrier frequency information are obtained. If the low frequency code of the current train is consistent with the low frequency code of the driver locked carrier frequency information, it is determined that the on-board device has not processed the driver locked carrier frequency information, and at this time it is determined that the on-board device correctly executes the track circuit information. If there is an inconsistency between the low frequency code of the current train and the low frequency code of the driver locked carrier frequency information, it is invalid to determine that the on-board device correctly executes the track circuit information, and at this time it is determined that the on-board device does not correctly execute the track circuit information.

[0096] When the on-board equipment monitoring mode is a full monitoring mode, and the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information, the method for judging whether the on-board equipment correctly executes the track circuit information is the same as the method for judging whether the on-board equipment correctly executes the track circuit information when the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information in the partial monitoring mode.

[0097] Furthermore, the present application also provides another embodiment, specifically, when the on-board device monitoring mode is the standby mode, and the first carrier frequency information is the driver locked carrier frequency information and / or the transponder locked carrier frequency information, the specific judgment of whether the on-board device correctly processes the track circuit information is as follows:

[0098] When the on-board device monitoring mode is the standby mode, and the first carrier frequency information is the driver locked carrier frequency information or the transponder locked carrier frequency information, it can be known that in the standby mode, the on-board device only processes the driver locked carrier frequency information, so it is necessary to determine whether the first carrier frequency information is the driver locked carrier frequency or the transponder locked carrier frequency information according to the carrier frequency signal source identifier. If the first carrier frequency information is the transponder carrier frequency information, the record of whether the on-board device processes the transponder carrier frequency information is obtained from the test recording module. If it is not processed, it means that in the standby mode, the on-board device does not process the transponder locked carrier frequency information. At this time, it is determined that the on-board device correctly processes the transponder locked carrier frequency information. If the record that the on-board device does not discard the transponder carrier frequency information is obtained from the test recording module, it is determined that the on-board device does not correctly process the transponder locked carrier frequency information. If the first carrier frequency information is determined to be the driver locked carrier frequency information according to the carrier frequency signal source identifier, the judgment method for judging whether the on-board device correctly executes the track circuit information is the same as the judgment method for judging whether the on-board device correctly executes the track circuit information in the partial monitoring mode when the first carrier frequency information is the driver locked carrier frequency.

[0099] When the on-board device monitoring mode is the standby mode, and the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information, if the transponder locked carrier frequency information is received after the driver locked the carrier frequency information, then the record of whether the on-board device processes the transponder carrier frequency information is obtained from the test recording module. If it is not processed, it means that the on-board device does not process the transponder locked carrier frequency information in the standby mode. At this time, it is determined that the on-board device correctly processes the transponder locked carrier frequency information. If the record of the on-board device not discarding the transponder carrier frequency information is obtained from the test recording module, it is determined that the on-board device does not correctly process the transponder locked carrier frequency information. If it is queried from the test recording module that the on-board device first receives the transponder locked carrier frequency information and then receives the driver locked carrier frequency information, it is first determined whether the on-board device discards the transponder locked carrier frequency information. If the transponder locked carrier frequency information is discarded, it is determined that the on-board device correctly processes the transponder locked carrier frequency information. If the on-board device does not discard the transponder locked carrier frequency information, it is determined that the on-board device does not correctly process the transponder locked carrier frequency information. If the on-board device receives the driver's locked carrier frequency information after discarding the transponder locked carrier frequency information, the current train low-frequency code and the driver's locked frequency low-frequency code are obtained. If the current train low-frequency code and the driver's locked frequency low-frequency code are consistent, it means that the on-board device controls the train operation only according to the driver's locked carrier frequency information. At this time, it is determined that the on-board device correctly handles the driver's locked carrier frequency information. If there is an inconsistency between the current train low-frequency code and the driver's locked frequency low-frequency code, it is determined that the on-board device did not correctly handle the driver's locked carrier frequency information.

[0100] Furthermore, the present application also provides another embodiment, specifically: when the on-board device monitoring mode is the shunting mode, and the first carrier frequency information is the driver locked carrier frequency information and / or the transponder locked carrier frequency information, the specific judgment of whether the on-board device correctly processes the track circuit information is as follows:

[0101] When the on-board device monitoring mode is the shunting mode, and the first carrier frequency information is the driver-locked carrier frequency information or the transponder-locked carrier frequency information, it can be known that in the standby mode, the on-board device only processes the driver-locked carrier frequency information, so it is necessary to determine whether the first carrier frequency information is the driver-locked carrier frequency or the transponder-locked carrier frequency information according to the carrier frequency signal source identifier. If the first carrier frequency information is the transponder carrier frequency information, the record of whether the on-board device processes the transponder carrier frequency information is obtained from the test recording module. If it is not processed, it means that in the standby mode, the on-board device does not process the transponder-locked carrier frequency information. At this time, it is determined that the on-board device correctly processes the transponder-locked carrier frequency information. If the record that the on-board device does not discard the transponder carrier frequency information is obtained from the test recording module, it is determined that the on-board device does not correctly process the transponder-locked carrier frequency information. If the first carrier frequency information is determined to be the driver-locked carrier frequency information according to the carrier frequency signal source identifier, the judgment method for judging whether the on-board device correctly executes the track circuit information is the same as the judgment method for judging whether the on-board device correctly executes the track circuit information in the partial monitoring mode when the first carrier frequency information is the driver-locked carrier frequency.

[0102] When the on-board device monitoring mode is the shunting mode, and the first carrier frequency information is the driver locked carrier frequency information and the transponder locked carrier frequency information, if the transponder locked carrier frequency information is received after the driver locked the carrier frequency information, then the record of whether the on-board device processes the transponder carrier frequency information is obtained from the test recording module. If it is not processed, it means that the on-board device does not process the transponder locked carrier frequency information in the standby mode. At this time, it is determined that the on-board device correctly processes the transponder locked carrier frequency information. If the record of the on-board device not discarding the transponder carrier frequency information is obtained from the test recording module, it is determined that the on-board device does not correctly process the transponder locked carrier frequency information. If it is queried from the test recording module that the on-board device first receives the transponder locked carrier frequency information and then receives the driver locked carrier frequency information, it is first determined whether the on-board device discards the transponder locked carrier frequency information. If the transponder locked carrier frequency information is discarded, it is determined that the on-board device correctly processes the transponder locked carrier frequency information. If the on-board device does not discard the transponder locked carrier frequency information, it is determined that the on-board device does not correctly process the transponder locked carrier frequency information. If the on-board device receives the driver's locked carrier frequency information after discarding the transponder locked carrier frequency information, the current train low-frequency code and the driver's locked frequency low-frequency code are obtained. If the current train low-frequency code and the driver's locked frequency low-frequency code are consistent, it means that the on-board device controls the train operation only according to the driver's locked carrier frequency information. At this time, it is determined that the on-board device correctly handles the driver's locked carrier frequency information. If there is an inconsistency between the current train low-frequency code and the driver's locked frequency low-frequency code, it is determined that the on-board device did not correctly handle the driver's locked carrier frequency information.

[0103] Furthermore, the present application also provides another embodiment, specifically: when the monitoring mode of the on-board equipment is a visual mode, and the first carrier frequency information is the driver-locked carrier frequency information and / or the transponder-locked carrier frequency information, the specific method for judging whether the on-board equipment correctly processes the track circuit information is the same as when the monitoring mode of the on-board equipment is a partial monitoring mode, and the first carrier frequency information is the driver-locked carrier frequency information and / or the transponder-locked carrier frequency information, and the judgment method is not repeated here.

[0104] Furthermore, the present application also provides another embodiment, specifically: when the on-board equipment monitoring mode is the guidance mode, and the first carrier frequency information is the driver-locked carrier frequency information and / or the transponder-locked carrier frequency information, the specific method for judging whether the on-board equipment correctly processes the track circuit information is the same as when the on-board equipment monitoring mode is the partial monitoring mode, and the first carrier frequency information is the driver-locked carrier frequency information and / or the transponder-locked carrier frequency information, and the judgment method is not repeated here.

[0105] Furthermore, as a response to the above Figure 1-3 In order to realize the method embodiment shown in the figure, the embodiment of the present invention also provides a test device for the on-board equipment to process the track circuit information, and the device is used to automatically and accurately determine whether the on-board equipment processes the track circuit information correctly.
