[0048] Figure 3 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0050] Specifically, the vehicle-to-ground transmission process in this embodiment of the application is as follows:

[0051] LTE sets up an indoor baseband unit (BBU) in the station to receive information transmitted from the remote radio unit (RRU) of the trackside equipment, and then transmits it to the central core network (Evolved Packet Core, EPC) through the safety network for processing.

[0052] The vehicle-mounted unit (TAU) transmits information to the RRU via an antenna and a leaky cable. Information can be transmitted bidirectionally, enabling vehicle-to-ground wireless communication.

[0053] Figure 1 This is a schematic flowchart of the train communication quality analysis method provided in the embodiments of this application, such as... Figure 1 As shown, it includes:

[0054] Step 110: When the first train passes through the first station, obtain the communication field strength information of the first train;

[0055] In this embodiment of the application, when analyzing the communication quality of the train, the specific analysis is of the communication quality between the train and the station.

[0056] More specifically, since there are significant differences in the environment between each station, the data of each station can be analyzed in this embodiment of the application. The first station can refer to any station on the train route, and this embodiment of the application does not limit this.

[0057] The first train described in this application embodiment may refer to a train that passes through a first station, and the first train has the function of communicating with the station.

[0058] In this embodiment of the application, the communication field strength information of the first train can specifically refer to the field strength value when the first train passes through the first station. The communication field strength information can effectively reflect the coverage strength of the LTE wireless field strength, thereby helping to determine whether the communication system is operating normally.

[0059] More specifically, the communication field strength information of the first train can be obtained by summarizing the information transmitted by the trackside receiving RRU set up at the first station and transmitting it to the central EPC for processing through the safety network.

[0060] Step 120: If the communication field strength information is lower than the first preset field strength threshold, generate a prompt message based on the difference between the communication field strength information and the first preset field strength threshold.

[0061] The first preset field strength threshold is determined based on the historical measurement value of the communication field strength of the target train model, where the target train model is the train model of the first train.

[0062] Specifically, since there are many different train models, their field strength values ​​may vary greatly, and the corresponding preset field strength thresholds are also different. The first preset field strength threshold described in this application embodiment is the preset field strength threshold corresponding to the target train model of the first train.

[0063] More specifically, in this embodiment of the application, the historical measurement value of the communication field strength is specifically the field strength information when a vehicle of the target model passes through the first station.

[0064] In this embodiment of the application, the historical measurement value of the communication field strength can be obtained by statistically analyzing the field information detected when the target model vehicle passes through the first station in the up (down) direction. Then, by accumulating a large amount of historical measurement value data of the communication field strength, the relatively normal and stable field strength value range corresponding to the first station can be obtained, thereby obtaining the first preset field strength threshold.

[0065] If the communication field strength information is lower than the first preset field strength threshold, it indicates that the communication field strength information of the first train may be low, the train communication quality is poor, and the communication equipment may need to be repaired or tested.

[0066] More specifically, the difference between the communication field strength information and the preset field strength threshold represents the quality of train communication. The larger the difference, the worse the communication quality, and the smaller the difference, the better the communication quality. Therefore, the embodiments of this application can generate different prompt messages according to the size of the difference.

[0067] In this embodiment of the application, the historical measurement value of the communication field strength of the first train is further obtained by the train model corresponding to the first train. The first preset field strength threshold of the first train is determined based on the historical measurement value of the communication field strength. Then, the communication field strength information of the first train is compared and analyzed based on the first preset field strength threshold. If the communication field strength information is lower than the first preset field strength threshold, a prompt message is generated, which effectively realizes a more accurate analysis of train communication quality.

[0068] Optionally, if the communication field strength information is lower than a first preset field strength threshold, a prompt message is generated based on the difference between the communication field strength information and the first preset field strength threshold, including:

[0069] When the communication field strength information is lower than a first preset field strength threshold but greater than a second preset field strength threshold, a fault detection prompt message is generated. The fault detection prompt message is used to instruct the first train to perform communication fault detection. The second preset field strength threshold is less than the first preset field strength threshold.

[0070] If the communication field strength information is lower than the second preset field strength threshold, a maintenance prompt message is generated.

[0071] Specifically, the second preset field strength threshold described in the embodiments of this application can be a standard for further analyzing whether the communication quality is too poor or even unable to achieve normal communication function. Therefore, the second preset field strength threshold is usually less than the first preset field strength threshold.

[0072] In this embodiment, if the communication field strength is lower than the first preset field strength threshold but higher than the second preset field strength threshold, it indicates that the communication quality of the first train is abnormal. Although maintenance personnel do not need to perform repairs immediately, further testing and analysis are required, and therefore a fault detection prompt message will be generated.

[0073] This fault detection alert can be used to deduce the correlation between abnormal vehicle-to-ground communication and trainset, station, or other factors through statistical analysis from different dimensions, enabling preliminary fault location, such as whether the roof antenna angle is deviated or whether the communication equipment needs cleaning. This helps prevent communication failures from occurring.

[0074] Optionally, if the communication field strength is lower than the second preset field strength threshold, it indicates that the communication quality of the first train is very poor and may not be able to communicate with the train. In this case, maintenance may be required, and maintenance prompt information can be generated to further prompt relevant personnel to carry out maintenance on the first train.

[0075] In this embodiment, different fault detection prompts are generated by comparing the communication field strength information with the first preset field strength threshold and the second preset field strength threshold, thereby effectively ensuring the normal operation of the communication system without affecting train operation.

[0076] Optionally, before the step of generating a prompt message based on the difference between the communication field strength information and the first preset field strength threshold, the method further includes:

[0077] Obtain historical measurements of the communication field strength of the target train model;

[0078] Based on the distribution of each of the historical measurements of the communication field strength in each consecutive preset field strength interval, a target preset field strength interval is determined, wherein the target preset field strength interval is the interval with the largest number of historical measurements of the communication field strength.

[0079] The first preset field strength threshold is determined based on the minimum field strength value within the target preset field strength range.

[0080] The continuous preset field strength interval described in the embodiments of this application can specifically be a pre-set interval.

[0081] Based on which preset field strength intervals the historical measurement values ​​of the communication field strength fall within, the distribution of the historical measurement values ​​of the communication field strength in each consecutive preset field strength interval can be obtained.

[0082] For example, when the first train passes the first station on the uphill route, most of the historical measurements of the communication field strength fluctuate within the range of a maximum of 55 and a minimum of 62, with a mean of 58.8, a variance of 2.4, and a standard deviation σ = 1.5. Therefore:

[0083] The field strength values ​​with 1 standard deviation σ mean ± standard deviation 93% are within the range of 1 σ, from 57 to -61; the field strength values ​​with 2 standard deviation 2 σ mean ± 2 standard deviation 97% are within the range of 2 σ, from 56 to -62, thus obtaining the preset field strength range.

[0084] More specifically, in this embodiment of the application, after determining the target preset field strength range, the minimum field strength value of the target preset field strength range can be used as the preset field strength threshold, which can effectively set a preset field strength threshold that can ensure communication security.

[0085] In this embodiment of the application, a reasonable first preset field strength threshold is effectively determined by using the historical measurement value of the communication field strength of the target train model, thereby effectively ensuring the communication quality of the train.

[0086] Optionally, determining the first preset field strength threshold based on the minimum field strength value within the target preset field strength range includes:

[0087] Obtain the station environment information of the first train when it passes through the first station;

[0088] The preset field strength threshold is determined based on the field strength influence information corresponding to the site environment information and the minimum field strength value.

[0089] Specifically, the site environment information described in the embodiments of this application may refer to weather information, humidity information, etc. around the site, and may also include the site's architectural environment.

[0090] The station environment in this application embodiment may also affect the train's communication. For example, the field strength value will be significantly attenuated in rainy weather or when the humidity is high. Such scenarios will be taken into account when making statistics.

[0091] Therefore, in this embodiment of the application, the field strength influence information corresponding to the station environment information will be determined based on the station environment information when the first train passes through the first station.

[0092] After obtaining the field strength influence information, the field strength interference coefficient can be determined based on the field strength influence information, and then the preset field strength threshold can be determined by combining the minimum field strength value.

[0093] In this embodiment, the influence of environmental factors on the communication field strength when the first train passes through the first station is fully considered. The minimum field strength value of the target preset field strength range is adjusted according to the field strength influence information corresponding to the station environment information, and the first preset field strength threshold is determined, which effectively ensures the accuracy of the first preset field strength threshold.

[0094] Optionally, after the step of generating a prompt message based on the difference between the communication field strength information and the first preset field strength threshold, the method further includes:

[0095] Obtain the generation time of each of the aforementioned prompt messages;

[0096] Based on the generation times described above, a time distribution analysis is performed to obtain time distribution information;

[0097] Specifically, in this embodiment of the application, the number of abnormal field strength values ​​at different time periods when the first train passes through the first station can be further counted, and the correlation with time can be observed.

[0098] By analyzing whether outliers occur relatively concentrated in a certain time period, we can detect any special characteristics of this time period and whether related operations are causing interference, thereby obtaining information on the time distribution of outlier occurrences.

[0099] In this embodiment, a maintenance guidance signal is generated based on time distribution information. Specifically, the time period for generating high-frequency prompt information can be marked, and maintenance personnel can be guided to perform communication maintenance during that time period, thereby effectively eliminating communication faults.

[0100] In this embodiment of the application, by performing time distribution analysis on the generation time of each prompt message, the time distribution information can be effectively determined, thereby generating maintenance guidance signals for maintenance guidance in a more targeted manner.
