Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, device, monitoring equipment, and storage medium for monitoring train operation information. Background Technology

[0002] During operation, trains need to exchange train operation information with station terminals to ensure accurate train scheduling. For example, when a train is approaching a station, station staff can send the track number to the train terminal in advance through the station terminal. When the train terminal receives the track number, it displays the track number to guide the driver to operate the train to enter the station via the track corresponding to that number.

[0003] In some cases, communication between the train terminal and the station terminal may fail. To investigate the cause of the failure, maintenance personnel need to carry a USB drive to copy train operation information in the first format (such as coded voice data or communication signaling carrying text information) from both the station terminal and the train terminal at different times. This requires maintenance personnel to travel between various stations and trains, resulting in high labor and time costs. Additionally, maintenance personnel need to consult technical manuals to find the corresponding second-format train operation information. Then, based on the second-format train operation information, maintenance personnel can determine the cause of the communication failure between the train terminal and the station terminal. Therefore, determining the cause of the communication failure between the train terminal and the station terminal is complex and incurrs high time and labor costs. Summary of the Invention

[0004] This application provides a method, device, monitoring equipment, and storage medium for monitoring train operation information, which solves the problems of complex causes, high time and labor costs in determining communication failures between train terminals and station terminals in the prior art.

[0005] Firstly, this application provides a method for monitoring train operation information, including:

[0006] When powered on, the monitoring equipment monitors train operation information in a first format exchanged between the train terminal and the station terminal within a specified frequency band.

[0007] The monitoring equipment analyzes the train operation information in the first format to obtain train operation information in the second format.

[0008] The monitoring equipment displays train operation information in the second format.

[0009] In one possible implementation, the monitoring equipment includes a low-end digital radio and a high-end digital radio, the specified frequency band range includes a first sub-band and a second sub-band, the train terminal includes a fixed train terminal and a mobile train terminal, and the station terminal includes a fixed station terminal and a mobile station terminal.

[0010] Then, within the specified frequency band, train operation information in a first format exchanged between the train terminal and the station terminal is monitored, including:

[0011] The monitoring equipment monitors train operation information in a first format exchanged between train mobile terminals and station mobile terminals in the first sub-band via a low-end digital radio.

[0012] The monitoring equipment monitors train operation information in the first format exchanged between train fixed terminals and station fixed terminals in the second sub-band via a high-end digital radio.

[0013] In this way, train operation information in the first format that is exchanged between train mobile terminals and station mobile terminals can be monitored separately from train operation information in the first format that is exchanged between train fixed terminals and station fixed terminals, thus improving the reliability of monitoring.

[0014] In one possible implementation, the method provided in this application further includes:

[0015] When the monitoring equipment is powered on, it monitors the signal strength of the communication signals containing train operation information in the first format that are exchanged between the train terminal and the station terminal at different times.

[0016] The monitoring equipment plots curves showing the change in signal strength of communication signals at different times.

[0017] The monitoring equipment displays the curves showing the change in signal strength of the communication signal at different times.

[0018] In this way, maintenance personnel can view the signal strength variation curves of communication signals at different times on the monitoring equipment, so as to more accurately analyze the reasons for communication failures between the train terminal and the station terminal.

[0019] In one possible implementation, after the monitoring equipment parses and detects train operation information in the first format to obtain train operation information in the second format, the method provided in this application further includes:

[0020] The monitoring equipment transmits the train operation information in the second format to the PC, so that the PC can filter and display the train operation information in the second format.

[0021] In this way, maintenance personnel can view the filtered train operation information in the second format on a PC, enabling them to quickly and accurately analyze the cause of communication failures between the train terminal and the station terminal.

[0022] In one possible implementation, the monitoring device, in response to an input download command, transmits train operation information in a second format to a USB flash drive for storage.

[0023] In this way, maintenance personnel can download the train operation information in the second format from the monitoring equipment to a USB flash drive for future reference.

[0024] In one possible implementation, the method provided in this application further includes:

[0025] The monitoring equipment collects its location information;

[0026] The monitoring equipment displays location information while simultaneously displaying train operation information in the second format.

[0027] This allows maintenance personnel to clearly see their current location and thus determine the station they are at.

[0028] In one possible implementation, the method provided in this application further includes:

[0029] When the battery level exceeds a set threshold, the monitoring device generates an alarm message to indicate low battery.

[0030] When the battery level exceeds a set threshold, the monitoring device displays an alarm message indicating low battery.

[0031] In this way, maintenance personnel can detect alarm messages when the monitoring equipment's battery is low.

[0032] Secondly, this application also provides a monitoring device for train operation information, comprising:

[0033] The information monitoring unit is used to monitor train operation information in a first format that is exchanged between the train terminal and the station terminal within a specified frequency band when the monitoring equipment is powered on.

[0034] The information parsing unit is used to parse the monitored train operation information in the first format to obtain train operation information in the second format.

[0035] The information display unit is used to display train operation information in the second format.

[0036] Thirdly, embodiments of this application also provide a computer-readable storage medium storing a computer program, which, when executed by a processor, causes the computer to perform the method provided in the above embodiments.

[0037] Fourthly, embodiments of this application also provide a server, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it causes the server to perform the method provided in the above embodiments.

[0038] Fifthly, embodiments of this application also provide a computer program product, including a computer program that, when run, causes a computer to perform the methods provided in the above embodiments.

[0039] This application provides a method, device, monitoring equipment, and storage medium for monitoring train operation information. When the monitoring equipment is powered on, it can automatically monitor train operation information in a first format exchanged between the train terminal and the station terminal within a specified frequency band. This eliminates the need for maintenance personnel to carry USB drives to copy information separately from the station and train terminals, saving time and manpower costs. The monitoring equipment parses the monitored train operation information in the first format to obtain train operation information in a second format; the monitoring equipment then displays the train operation information in the second format. Thus, maintenance personnel can browse the train operation information in the second format on the monitoring equipment without manually consulting manuals to find the corresponding text information for communication signals, further saving time and manpower costs.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments made by those skilled in the art under the guidance of these embodiments are within the scope of protection of this application.

[0049] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0050] First, let me explain the terms used in this application:

[0051] Train wireless dispatch communication: Train radio communication used for train dispatching and command.

[0052] Fixed radio control equipment: Equipment used to manage fixed radio stations and handle voice and data services in train radio communications.

[0053] Fixed radio: A digital wireless train dispatching system radio installed at locations such as railway stations, track crossings, and flood control points.

[0054] During operation, trains need to exchange train operation information with station terminals to ensure accurate train scheduling. In some cases, communication between the train terminal and the station terminal may fail, requiring maintenance personnel to incur significant time and manpower costs in order to investigate the cause of the failure.

[0055] Based on the above-mentioned technical problems, the inventive concept of this application is: when the monitoring equipment is powered on, it can automatically monitor the train operation information with a first format that is exchanged between the train terminal and the station terminal within a specified frequency band, without requiring maintenance personnel to carry a USB flash drive to copy the information from the station terminal and the train terminal respectively, thus saving time and manpower costs.

[0056] In addition, the monitoring equipment parses the train operation information in the first format to obtain train operation information in the second format; the monitoring equipment then displays the train operation information in the second format. In this way, maintenance personnel can browse the train operation information in the second format on the monitoring equipment without manually searching through manuals to find the corresponding text information for communication signals, further saving time and manpower costs.

[0057] The technical solutions of this application and how they solve the aforementioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0058] Please see Figure 1 This application provides a method for monitoring train operation information, applied to a monitoring device 100. The monitoring device 100 can be communicatively connected to a train terminal 200 and a station terminal 300 for wireless train dispatching communication. The station terminal 300 can be a fixed radio control device, fixed radio, dispatch radio, station operation radio, walkie-talkie, station dispatch terminal, user operation terminal, or digital wireless train fixed terminal located in the station's dispatching room; no limitation is made herein. The train terminal 200 can be an onboard terminal, walkie-talkie, etc.; no limitation is made herein.

[0059] Specifically, such as Figure 2 As shown, the monitoring device 100 includes a monitoring unit 202, a main control unit 201, and a display unit. The main control unit 201 is connected to both the monitoring unit 202 and the display unit.

[0060] like Figure 3 As shown in the embodiments of this application, the method for monitoring train operation information includes:

[0061] S301: When the monitoring device 100 is powered on, it monitors the train operation information with a first format that is exchanged between the train terminal 200 and the station terminal 300 within a specified frequency band.

[0062] It should be noted that the monitoring device 100 may be equipped with a switch, and the monitoring device 100 is powered on when the switch is turned on.

[0063] Typically, train dispatching at a station relies on the exchange of train operation information in a first format between the monitoring train terminal 200 and the station terminal 300 within a specified frequency band. The first format refers to the format that enables the transmission of train operation information within the first frequency band. Train operation information may include business data, communication signaling, work logs, and voice call data between the station terminal 300 and the train terminal 200.

[0064] Understandably, the above-mentioned S301 can be executed by the monitoring unit 202.

[0065] Specifically, such as Figure 3 As shown, the monitoring unit 202 includes a low-end digital radio 204 and a high-end digital radio 205, and the designated frequency band range includes a first sub-band and a second sub-band. The train terminal 200 includes a fixed train terminal (such as an onboard terminal) and a mobile train terminal (such as a walkie-talkie), and the station terminal 300 includes a fixed station terminal (such as radio control equipment, a fixed radio) and a mobile station terminal (such as a walkie-talkie). Thus, as... Figure 4 As shown, the above-mentioned S301 may include:

[0066] S401: Monitoring equipment 100 monitors train operation information in a first format exchanged between train mobile terminals and station mobile terminals in the first sub-band via low-end digital radio 204.

[0067] Both the train mobile terminal and the station mobile terminal can be, but are not limited to, walkie-talkies.

[0068] S402: Monitoring equipment 100 monitors train operation information in a first format exchanged between train fixed terminals and station fixed terminals in the second sub-band via high-end digital radio 205.

[0069] For example, the train fixed terminal can be an onboard terminal, and the station fixed terminal can be, but is not limited to, a fixed radio control device, a fixed radio, a dispatching radio, and a station operation radio installed in the dispatching room of the station.

[0070] In this way, train operation information in the first format that is exchanged between train mobile terminals and station mobile terminals can be monitored separately from train operation information in the first format that is exchanged between train fixed terminals and station fixed terminals, thus improving the reliability of monitoring.

[0071] S302: The monitoring equipment 100 analyzes the monitored train operation information in the first format to obtain train operation information in the second format.

[0072] For example, the second format refers to the format that enables the train operation information to be displayed by the monitoring device 100. For example, when the train operation information is voice call data, the undecoded voice call data can be parsed to obtain decoded voice call data, and then the decoded voice call data can be converted into text information.

[0073] Understandably, the aforementioned S302 can be executed by the main control unit 201. The main control unit 201 can also store train operation information monitored within a preset time period.

[0074] S303: Monitoring equipment 100 displays train operation information in the second format.

[0075] In this way, maintenance personnel can view train operation information from monitoring equipment 100, and analyze the reasons for communication failures between train terminal 200 and station terminal 300 based on the train operation information.

[0076] For example, S303 described above can be performed by a display unit. For example, the display unit can be, but is not limited to, a liquid crystal display screen.

[0077] In summary, the train operation information monitoring method provided in this application embodiment can automatically monitor train operation information in a first format exchanged between the train terminal 200 and the station terminal 300 within a specified frequency band when the monitoring device 100 is powered on. This eliminates the need for maintenance personnel to carry USB drives to copy information from both the station terminal 300 and the train terminal 200, saving time and manpower costs. The monitoring device 100 parses the monitored train operation information in the first format to obtain train operation information in a second format; the monitoring device 100 then displays the train operation information in the second format. Thus, maintenance personnel can browse the train operation information in the second format on the monitoring device 100 without manually searching through manuals to find the corresponding text information for the communication signals, further saving time and manpower costs.

[0078] In addition, Figure 3 Based on the corresponding embodiments, such as Figure 5 As shown, the method provided in this application embodiment may further include:

[0079] S501: When the monitoring device 100 is powered on, it monitors the signal strength of the communication signal with the first format of train operation information exchanged between the train terminal 200 and the station terminal 300 at different times.

[0080] It should be noted that the frequency of monitoring signal strength can be once per second.

[0081] S502: Monitoring device 100 plots the curve of the change in signal strength of the communication signal at different times.

[0082] S503: Monitoring device 100 displays the curve of the change in signal strength of communication signal at different times.

[0083] In this way, maintenance personnel can view the signal strength variation curve of the communication signal at different times on the monitoring equipment 100, so as to more accurately analyze the cause of communication failure between the train terminal 200 and the station terminal 300.

[0084] Understandably, there is no sequential order between S501-S503 and the aforementioned S301-S303.

[0085] In addition, Figure 3 Based on the corresponding embodiment, after S303, the method provided in this application embodiment may further include: the monitoring device 100 transmits the train operation information in the second format to the PC terminal, so that the PC terminal filters and displays the train operation information in the second format.

[0086] This includes the ability to export an Excel spreadsheet containing train operation data to a PC. Additionally, when the monitored data includes voice call data, the exported data can also include a ".wav" format audio file.

[0087] In this way, maintenance personnel can view the filtered train operation information in the second format on a PC, so as to quickly and accurately analyze the cause of communication failure between the train terminal 200 and the station terminal 300.

[0088] In addition, Figure 3 Based on the corresponding embodiment, after S303, the monitoring device 100, in response to the input download command, transmits the train operation information in the second format to a USB flash drive for storage. In this way, maintenance personnel can download the train operation information in the second format from the monitoring device 100 to the USB flash drive for future reference.

[0089] In addition, Figure 3Based on the corresponding embodiments, the method provided in this application may further include: the monitoring device 100 collecting its location information. The monitoring device 100 may include a GPS positioning antenna, which can be used to collect location information. The monitoring device 100 displays location information simultaneously with the train operation information in the second format. This allows maintenance personnel to clearly see their current location and thus determine the station where they are located.

[0090] In one possible implementation, the method provided in this application further includes: the monitoring device 100 generating an alarm message indicating insufficient battery power when the battery power level exceeds a set power threshold; and the monitoring device 100 displaying the alarm message indicating insufficient battery power when the battery power level exceeds the set power threshold. In this way, maintenance personnel can be aware of the alarm message output by the monitoring device 100 indicating insufficient battery power.

[0091] In addition, such as Figure 2 As shown, the monitoring device 100 provided in this embodiment includes a power interface 206, which can be connected to AC-220V mains power to obtain power for the monitoring device 100. Additionally, the monitoring device 100 may also include a battery 207, which can also supply power to the monitoring device 100.
