[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant regulations.

[0042] The rail damage monitoring method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the rail damage monitoring system 100 includes a monitoring terminal 120, a terminal edge device 140 and a cloud analysis platform 160. The monitoring terminal 120 is connected to the rail 20 by a thread. When the train 10 passes through the rail 20 during driving, a corresponding vibration signal will be generated.

[0043] The monitoring terminal 120 may include but is not limited to sensors, control chips, and battery compartments. The monitoring terminal 120 may use the power provided by the battery compartment to control the operation of the sensors and control chips. The monitoring terminal 120 collects vibration signals of the rails 20 through sensors. The monitoring terminal 120 may compare the vibration signals collected by the sensors and the abnormal signals collected when the rails 20 are damaged through the control chip, and when the vibration signals of the rails 20 match the abnormal signals, the vibration signals are sent to the terminal edge device 140 via Bluetooth transmission.

[0044] The terminal edge device 140 can be deployed within a preset range (e.g., 15 meters) of the monitoring terminal 120. The terminal edge device 140 can communicate with the monitoring terminal 120 via Bluetooth signals. The terminal edge device 140 can be used to receive the vibration signal sent by the monitoring terminal 120 and send the vibration signal to the cloud analysis platform 160. Optionally, in some embodiments, the terminal edge device 140 can be deployed with a lithium battery to supply energy through the lithium battery. Optionally, as Figure 2 As shown, a schematic diagram of a terminal edge device 140 is provided. The terminal edge device 140 can be implemented by using a gateway.

[0045] The cloud analysis platform 160 can communicate with the terminal edge device 140 through a digital communication network (such as a 2G, 4G or 5G transmission network). The cloud analysis platform 160 can be used to receive the vibration signal sent by the terminal edge device 140 and generate a damage monitoring result of the rail 20 according to the vibration signal.

[0046] The above-mentioned rail damage monitoring system, by connecting the monitoring terminal to the rail with threads, can achieve the effect of preventing loosening and rotation, which is more suitable for the use scenario of railway turnouts and greatly reduces the risk of accidents in on-site use. By setting sensors, control chips and battery compartments in the monitoring terminal, using the battery compartment to provide power for the sensors and control chips, and sending the vibration signals detected by the sensors to the terminal edge device through the control chip in the form of Bluetooth signals, wireless passive rail damage monitoring can be achieved, which not only reduces the difficulty of on-site installation of the rail damage monitoring system, but also avoids the risk of on-site electricity use.

[0047] In some exemplary embodiments, Figure 3 As shown, the monitoring terminal 120 may also include a sensor 122 and a sensor base 124. The sensor base 124 and the sensor 122 may be connected by threads, and the sensor base 124 is assembled with the rail 20 by interference fit through the existing electrical jumper hole 202 of the rail 20.

[0048] In this embodiment, the interference fit connection between the sensor base and the rail can help achieve the effect of preventing loosening and rotation.

[0049] Optionally, in some embodiments, the threaded portion between the sensor 122 and the sensor base 124 may be coated with anti-loosening glue. The end of the sensor 122 may be pressed tightly against the waist surface of the rail 20. Optionally, in some embodiments, the end size of the sensor 122 may be designed to protrude only 7 mm from the waist portion of the rail 20, so that the rail 20 after the monitoring terminal 120 is installed will not affect the closed fit between the point rail and the base rail when it is installed at the tip area of ​​the point rail.

[0050] In this embodiment, by pressing the sensor tightly against the waist surface of the rail, the transmission quality of the vibration signal can be guaranteed and the accuracy of the vibration signal monitored by the sensor can be improved.

[0051] In an exemplary embodiment, Figure 4 As shown, a structural schematic diagram of a monitoring terminal 120 is also provided, including a fastening bolt 121, a non-metallic cover plate 123, a waterproof gasket 125, a circuit board 127, a battery compartment 129, and having a mounting thread.

[0052] The fastening bolt 121 may be an M2 bolt.

[0053] Sensors and control chips may be deployed in the circuit board 127 to form a circuit microsystem of the monitoring terminal 120 .

[0054] The monitoring terminal 120 can fasten the non-metallic cover plate 123 by fastening bolts 121 to press the waterproof gasket 125, the circuit microsystem of the circuit board 127 and the battery compartment 129 into a whole.

[0055] In this embodiment, by adopting a monitoring terminal composed of fastening bolts, a non-metallic cover plate, a waterproof gasket, a circuit board and a battery compartment, the connection stability of the monitoring terminal can be improved, and it is also convenient for disassembly and maintenance.

[0056] In an exemplary embodiment, Figure 5A As shown, when the number of monitoring terminals 120 is one, the terminal edge device 140 and the monitoring terminal 120 can perform one-to-one single-point communication via Bluetooth signals. Figure 5B As shown, when there are multiple monitoring terminals 120, the multiple monitoring terminals 120 can form a network. The terminal edge device 140 can perform one-to-many communication with the network formed by the multiple monitoring terminals 120 through Bluetooth signals.

[0057] In this embodiment, through one-to-one or one-to-many signal transmission between the terminal edge device and the monitoring terminal, the scalability and deployment flexibility of the rail damage monitoring system can be improved.

[0058] In an exemplary embodiment, the monitoring terminal 120 may also be used to control the sensor to collect vibration signals at a working frequency when the sensor detects the train load. Alternatively, when the sensor cannot detect the train load, the monitoring terminal 120 may control the sensor to collect vibration signals at a sleep frequency, wherein the working frequency is higher than the sleep frequency.

[0059] For example, when the train 10 passes through the rail area where the monitoring terminal 120 is located, the monitoring terminal 120 can detect a train load greater than zero through a sensor. At this time, the monitoring terminal 120 can control the sensor to collect vibration signals at a higher operating frequency when the sensor detects the train load. In this way, the complete high entropy information flow of the current vibration signal can be captured in time and transmitted.

[0060] When the train 10 does not reach the rail area where the monitoring terminal 120 is located, the train load detected by the monitoring terminal 120 through the sensor is zero. At this time, the monitoring terminal 120 can control the sensor to collect vibration signals at the sleep frequency when the sensor cannot detect the train load, so as to reduce the current power consumption and extend the working time when the vibration signal is a low entropy information flow.

[0061] In this embodiment, by activating the monitoring terminal to collect vibration signals at a working frequency or a sleep frequency based on the train load, the service life of the monitoring terminal can be increased and the utilization rate of the monitoring terminal can be improved.

[0062] In an exemplary embodiment, the cloud analysis platform 160 can also be used to: construct a data model of the rail based on the vibration signal, determine the target location, damage form and damage degree of the rail based on the data model, and generate damage monitoring results based on the target location, damage form and damage degree.

[0063] Exemplarily, the cloud analysis platform 160 can perform data preprocessing operations such as denoising, cleaning, and standardization on the vibration signal to obtain a processed vibration signal value. The vibration signal waveform model is constructed using parameters such as vibration intensity, vibration frequency, and amplitude in the vibration signal value as a data model of the rail 20. The vibration state of each area of ​​the rail 20 is determined using the data model of the rail 20.

[0064] Optionally, in some embodiments, a preset vibration threshold may be used to compare with the vibration state of the current rail 20 in various regions. The region where the vibration state reaches the vibration threshold is determined as the target location where the rail 20 is damaged. The vibration state characteristics corresponding to different damage forms are compared with the vibration state at the target location to determine the damage form and damage degree at the target location.

[0065] Alternatively, in other embodiments, an abnormal data model constructed when different damage forms appear on the rail 20 may be compared with a data model currently constructed using a real-time vibration signal. According to the abnormal data model matching the current data model, the target position, damage form, and damage degree of the current damage on the rail 20 are located.

[0066] The cloud analysis platform 160 can generate the damage monitoring result of the current rail 20 by using the target location, damage form and damage degree of the damage on the rail 20.

[0067] In this embodiment, the abnormal vibration signal is processed and analyzed in detail by using the powerful analysis and storage capabilities of the cloud analysis platform to determine the target location, damage form and damage degree of the rail damage, and the damage monitoring results are generated using the target location, damage form and damage degree, which can improve the data richness of the damage monitoring results.

[0068] In an exemplary embodiment, Figure 6 As shown, the rail damage monitoring system 100 may further include a visualization interface 180 .

[0069] The visualization interface 180 can communicate with the cloud analysis platform 160 , and can be used to receive the damage monitoring results sent by the cloud analysis platform 160 , and display the damage monitoring results.

[0070] Exemplarily, the rail damage monitoring system 100 can collect the vibration signal of the rail 20 through the monitoring terminal 120. When the vibration signal of the rail 20 matches the abnormal signal, the monitoring terminal 120 sends the vibration signal of the rail 20 to the terminal edge device 140 in a Bluetooth communication manner. The rail damage monitoring system 100 can forward the vibration signal of the rail 20 to the cloud analysis platform 160 through the terminal edge device 140. The rail damage monitoring system 100 can generate the damage monitoring result of the rail 20 using the vibration signal of the rail 20 through the cloud analysis platform 160, and send the damage monitoring result to the visualization interface 180. The rail damage monitoring system 100 can display the damage monitoring result of the rail 20 through the visualization interface 180.

[0071] In this embodiment, when a vibration signal matching the abnormal signal is detected, a corresponding damage monitoring result is generated by using a cloud analysis platform and sent to the visualization interface 180 for display. This can improve the timeliness of damage warnings and intuitively provide operators with detailed damage information to facilitate damage repair.

[0072] In an exemplary embodiment, the visualization interface 180 may also communicate with an end-edge device.

[0073] The terminal edge device 140 may be used to receive the attribute information of the sensor sent by the monitoring terminal 120 when the vibration signal does not match the abnormal signal. The attribute information may include the current sensor working time, working voltage, ambient temperature and other information.

[0074] The visualization interface 180 may receive attribute information of the sensor sent by the terminal edge device 140 and display the attribute information.

[0075] Exemplarily, the rail damage monitoring system 100 can send the current attribute information of the sensor to the terminal edge device 140 through the monitoring terminal 120 when the collected vibration signal does not match the abnormal signal. The attribute information of the sensor is broadcast to the visualization interface 180 through the terminal edge device 140. The attribute information of the sensor is displayed through the visualization interface 180.

[0076] In this embodiment, by broadcasting and displaying only the attribute information of the sensor when the vibration signal does not match the abnormal signal, the current working status of the sensor can be intuitively displayed.

[0077] In an exemplary embodiment, Figure 7 As shown, a rail damage monitoring method is provided, which is applied to Figure 1 The rail damage monitoring system 100 in FIG. 1 is taken as an example to illustrate the method, which includes the following steps S702 to S706. Among them:

[0078] Step S702, collecting vibration signals of rails.

[0079] Step S704, comparing the vibration signal with the abnormal signal, where the abnormal signal is collected when the rail is damaged.

[0080] Step S706: when the vibration signal and the abnormal signal match, generate a rail damage monitoring result according to the vibration signal.

[0081] For example, the rail damage monitoring system can collect the vibration signal of the rail through the sensor of the monitoring terminal. The control chip of the monitoring terminal compares the current vibration signal and the abnormal signal collected when the rail is damaged. When the vibration signal and the abnormal signal match, the control chip of the monitoring terminal sends the vibration signal to the terminal edge device. The vibration signal is forwarded to the cloud analysis platform through the terminal edge device. The cloud analysis platform generates the rail damage monitoring result according to the vibration signal.

[0082] In the above-mentioned rail damage monitoring method, by comparing the vibration signal of the rail with the abnormal signal collected when the rail is damaged, when the vibration signal and the abnormal signal match, the rail damage monitoring result is generated according to the vibration signal, and the abnormal signal can be used for the initial screening of rail damage, reducing the amount of data that needs to be processed in the process of generating subsequent damage monitoring results, thereby improving the efficiency of rail damage monitoring.

[0083] In one embodiment, the rail damage monitoring method provided in the present application may also include: when the train load is monitored, collecting vibration signals at a working frequency, or, when the train load is not monitored, collecting vibration signals at a sleep frequency, and the working frequency is higher than the sleep frequency.

[0084] For example, the rail damage monitoring system can identify the train load through the sensor of the monitoring terminal. When the sensor detects the train load, the sensor of the monitoring terminal is controlled to collect the high entropy information flow of the vibration signal at a higher working frequency. Alternatively, the rail damage monitoring system can also control the sensor of the monitoring terminal to collect the low entropy information flow of the vibration signal at a lower sleep frequency when the sensor cannot detect the train load.

[0085] In this embodiment, the train load is used to activate the sensor in the dormant state and increase the frequency of the sensor collecting vibration signals. This can not only improve the signal transmission efficiency of the sensor in the case of high entropy information flow of the train load, but also reduce the sensor energy consumption in the case of low entropy information flow without train load, thereby improving the utilization rate and service life of the sensor.

[0086] In one of the embodiments, the rail damage monitoring method provided in the present application also includes: constructing a data model of the rail based on the vibration signal, determining the target position, damage form and damage degree of the rail damage based on the data model, and generating a damage monitoring result based on the target position, damage form and damage degree.

[0087] For example, the rail damage monitoring system can refer to the method for generating damage monitoring results provided in the above embodiment through the cloud analysis platform, build a data model of the rail according to the vibration signal, and determine the target position, damage form and damage degree of the rail damage according to the data model of the rail. The damage monitoring result of the rail is generated according to the target position, damage position and damage degree of the rail damage.

[0088] In this embodiment, a data model of the rail is constructed based on the vibration signal, and the target position, damage form and damage degree of the rail located using the data model are used to generate damage monitoring results, which can improve the generation efficiency and information richness of the damage monitoring results.

[0089] In one of the embodiments, the rail damage monitoring method provided in the present application further includes: displaying damage monitoring results.

[0090] For example, after the rail damage monitoring system generates the damage monitoring result through the cloud analysis platform, the damage monitoring result can be sent to the cloud analysis platform, and the damage monitoring result can be displayed through the cloud analysis platform.

[0091] In this embodiment, by displaying the damage monitoring results, the operator can be promptly prompted to repair the rail damage, which helps the operator to quickly determine the corresponding damage repair plan.

[0092] In one of the embodiments, the rail damage monitoring method provided in the present application further includes: receiving attribute information of a sensor sent when the vibration signal does not match the abnormal signal, and displaying the attribute information.

[0093] For example, the rail damage monitoring system can send the current attribute information of the sensor to the terminal edge device through the monitoring terminal when the vibration signal does not match the abnormal signal. The attribute information of the sensor is broadcast to the visualization interface through the terminal edge device. The attribute information of the sensor is displayed through the visualization interface.

[0094] In this embodiment, by displaying the attribute information of the sensor when no rail damage is detected, it can help the operator to intuitively understand the current working status of the sensor and enrich the amount of information that the operator can obtain.

[0095] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the indications of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of the steps or stages in other steps.
