[0051] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

It should also be understood that the terms "include," "comprising," "having," and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains.

[0056] The GSM-R system, a railway wireless network, differs from other wireless network systems in that it is specifically designed for railway communications. The current GSM-R system has been in operation for many years, and its supporting equipment has generally experienced a high rate of failures. Railway operations such as train dispatching and control rely on the GSM-R network. To ensure train safety, it is necessary to monitor the quality of the GSM-R network along the railway.

[0057] Currently, wireless signal quality monitoring products on the market are mainly implemented in the following two ways: one is to install monitoring terminals along the railway for remote monitoring; the other is to use a special signal vehicle to run along the railway tracks once a month for monitoring.

[0058] However, the applicant discovered that both of these approaches have shortcomings. While the first approach allows for remote monitoring by installing monitoring equipment along the railway line, the monitoring terminals can only obtain data from the network system at those locations. Excessive installations lead to high construction costs and difficult maintenance, while too few lead to severe monitoring reliability issues. Furthermore, the data volume is too small for reliable monitoring of the entire railway section. The second approach involves using dedicated signal vehicles to operate along the route for monitoring. While this approach can provide visibility into the system status of the entire section, it only monitors once a month, failing to provide real-time visibility into the operational status of the railway wireless network. This poses risks and leads to deficiencies in monitoring reliability.

[0059] Therefore, in order to improve the reliability of railway signal detection, the applicant has conceived the technical solution of the present application. In one embodiment, Figure 1As shown, the present application provides a railway signal detection system, including two or more signal detection devices 120 and a control platform 140. Each signal detection device 120 is respectively installed in a different train and is communicatively connected to the train's control equipment. The control platform 140 is communicatively connected to each signal detection device 120. Among them, the signal detection device 120 is used to obtain train operation parameters and railway signal parameters, and transmit them to the control platform 140. The control platform 140 is used to detect and analyze railway signals based on each train operation parameter and each railway signal parameter.

[0060] Railways consist of multiple tracks for trains. Trains operate or adjust their routes based on railway dispatch requirements, communicating with each other and with the control center via the GSM-R network. Train control equipment, which provides overall control of the train, including speed and route, requires connectivity to the GSM-R network to ensure timely dispatch. Train control equipment can include CIR (Cellular Integrated Radio Communication) equipment, which is compatible with the GSM-R network system and can access the GSM-R network to enable communication between the train and the control center, other trains, and personnel, ensuring safe and efficient train operation.

[0061] The signal detection device is set on the train. A signal detection device can be set on each train, a signal detection device can be set on the train participating in signal detection, or a signal detection device can be configured on each carriage of the train. In this embodiment, there is no specific limitation on the setting of the signal detection device, and multiple signal detection devices can be set on different trains.

[0062] The signal detection equipment communicates with the train's control equipment, particularly the CIR equipment, and can obtain the train's operating parameters, such as the train's current position, current speed, and route, as well as train signal parameters obtained through interaction between the CIR equipment and the GSM-R network system. Furthermore, the signal detection equipment can also communicate directly with the GSM-R network system, interacting with it to obtain railway signal parameters, such as the current wireless network signal strength. The signal detection equipment can continuously obtain train operating parameters and railway signal parameters during train operation and transmit these parameters to the control platform.

[0063] The control and management platform is a computing platform built to manage railway operations. It can be either terminal-based or server-based. It communicates with various signal detection devices and receives train operating parameters and railway signal parameters from them. Relying on its operational capabilities, the control and management platform analyzes these parameters, completing railway signal detection and analysis, and obtaining railway signal detection results, such as the quality of the GSM-R network signal at various locations along the railway route and the presence of dangerous GSM-R network disconnections.

[0064] Exemplarily, the management and control platform can be a terminal or a server. The terminal can be, but is not limited to, various personal computers, laptops, smartphones, tablet computers, etc. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The communication connection method in this application can be a wired connection or a wireless connection, and is not limited to them unless otherwise specified. The methods of wired communication connection and wireless communication connection are also not limited.

[0065] In this embodiment, the railway signal detection system includes two or more signal detection devices and a control and management platform. Each signal detection device is installed on a different train and is in communication with the train's control equipment. The control and management platform is in communication with each signal detection device. The signal detection device is used to obtain train operating parameters and railway signal parameters and transmit them to the control and management platform. The control and management platform is used to detect and analyze railway signals based on these parameters. By installing signal detection devices on each train and uploading these parameters to the control and management platform in real time, real-time network signal detection is performed at all railway locations, enabling timely detection of network signal failures and improving the reliability of railway signal detection.

[0066] In one exemplary embodiment, Figure 2 As shown, the signal detection device includes a signal acquisition unit 122 and a main control unit 124. The main control unit 124 is connected to the train control device, the signal acquisition unit 122 and the management and control platform 140. The signal acquisition unit 122 is used to obtain railway signal parameters, and the main control unit 124 is used to obtain train operation parameters.

[0067] The signal acquisition unit is used to establish a communication connection with a railway wireless network. The railway wireless network can be a GSM-R network, and in this case, the signal acquisition unit is a GSM-R signal acquisition unit. It is understood that if different railway wireless networks are used, the corresponding signal acquisition unit can communicate with different network types. This embodiment and subsequent embodiments are described only using the GSM-R network as an example, and the solution of this application is not limited to the GSM-R network.

[0068] The main control unit (MCU) is the main control chip of the signal detection equipment, responsible for data calculation, data transmission, and unit control during railway signal detection. The MCU, which can be a processor chip or single-chip microcomputer with sufficient computing power, establishes a communication connection with the train's control equipment to obtain train operating parameters from the CIR equipment. The MCU is also connected to the signal acquisition unit, controlling when the unit activates (for example, only when the CIR equipment indicates the train is in motion) to collect GSM-R signals. It also interacts with the signal acquisition unit to obtain railway signal parameters collected by the unit. The MCU obtains railway signal parameters and train operating parameters and, through a communication connection with the control platform, uploads them to the control platform. The control platform analyzes the aggregated parameters to generate railway signal detection results.

[0069] Furthermore, the signal acquisition unit can also be connected to the GSM-R network through the antenna unit. The antenna unit serves as a signal amplifier or an auxiliary communication protocol to facilitate the connection between the signal acquisition unit and the GSM-R network to obtain railway signal parameters.

[0070] In one exemplary embodiment, Figure 2 As shown, the signal detection device 120 further includes an Internet of Things communication unit 126 , and the main control unit 124 is communicatively connected to the management and control platform 140 via the Internet of Things communication unit 126 .

[0071] The IoT communication unit can provide a 4G / 5G communication network. The main control unit can communicate with the management and control platform in the form of the IoT through the IoT communication unit, realizing railway signal detection that integrates public and private networks in the railway system, and making full use of the advantages of IoT deployment and the professionalism of the GSM-R network.

[0072] In one exemplary embodiment, the signal detection device includes a power supply unit configured to supply power to the signal acquisition unit and the main control unit. Furthermore, when the signal detection device includes an IoT communication unit, the power supply unit is also connected to the IoT communication unit to supply power to the IoT communication unit.

[0073] Furthermore, the power supply requirements of the signal acquisition unit and the main control unit may or may not be the same, so the voltage stabilizing circuit can power the signal acquisition unit and the main control unit separately. In one embodiment, the power supply unit includes a first voltage stabilizing circuit and a second voltage stabilizing circuit, the first voltage stabilizing circuit being connected to an external power supply, the second voltage stabilizing circuit, and the main control unit, and the second voltage stabilizing circuit being connected to the signal acquisition unit.

[0074] Specifically, the first voltage stabilizing circuit adjusts the voltage of the external power supply to obtain a first voltage, which is used to power the main control unit. The second voltage stabilizing circuit receives the first voltage, adjusts the first voltage to obtain a second voltage, and uses the second voltage to power the signal acquisition unit.

[0075] Optionally, if the power supply requirement of the Internet of Things communication unit is consistent with that of the signal acquisition unit, the second voltage stabilizing circuit is connected to the Internet of Things communication unit and uses the second voltage to power the Internet of Things communication unit.

[0076] In this embodiment, by supplying different voltages to different units, the power supply requirements of the signal acquisition unit and the main control unit are met respectively, so as to ensure the stable power supply of both, thereby achieving stable operation and improving the reliability of railway signal detection.

[0077] In order to better understand the above solution, a detailed explanation is given below in conjunction with a specific embodiment.

[0078] In one embodiment, Figure 3 As shown, the signal detection equipment in the railway signal detection system includes a main control unit, a GSM-R signal acquisition unit, an Internet of Things communication unit and a power supply unit. The power supply unit includes a first voltage stabilizing circuit and a second voltage stabilizing circuit. The connection relationship between them has been recorded above and will not be repeated here.

[0079] An external power supply input of 110V supplies power to the first voltage-stabilizing circuit. The first voltage-stabilizing circuit outputs a first voltage of 5V, which powers the main control unit and transmits the output to the second voltage-stabilizing circuit. The second voltage-stabilizing circuit regulates the 5V to a second voltage of 3.7V, which is then used to power the GSM-R signal acquisition unit and the IoT communication unit.

[0080] The main control unit receives input signals from the CIR device, acquiring train operating parameters and controlling the GSM-R signal acquisition unit to begin collecting GSM-R signals, representing railway signal parameters. The main control unit then uploads these train operating and railway signal parameters to the control and management platform via the IoT communication unit, completing data collection and transmission. The control and management platform receives these train operating and railway signal parameters from multiple signal detection devices and analyzes them to complete railway signal detection. The resulting railway signal detection results indicate the quality of the GSM-R wireless network signal.

[0086] Based on the same technical concept, the present application also provides a railway signal detection method, which can be applied to Figure 1 In the application environment shown, the railway signal detection system described in the above embodiments is implemented.

[0087] In an exemplary embodiment, Figure 2 As shown, a railway signal detection method is provided, which is applied to Figure 8 The control platform 140 in FIG. 1 is used as an example to illustrate the process, including the following steps 202 to 206. Among them:

[0088] Step 202: Acquire signal detection data uploaded by different signal detection devices.

[0089] Each signal detection device is installed on a different train, and the signal detection data includes train operating parameters and railway signal parameters. The signal detection device communicates with the train's CIR device and can obtain operating parameters such as the train's current location, speed, and route, as well as train signal parameters obtained through interaction between the CIR device on the train and the GSM-R network system. Furthermore, the signal detection device can directly communicate with the GSM-R network system, interacting with it to obtain railway signal parameters, such as the current wireless network signal strength.

[0090] Specifically, the signal detection equipment continuously acquires train operation parameters and railway signal parameters during train operation, and transmits these parameters to the control platform. The control platform is connected to multiple signal detection devices and can obtain signal detection data uploaded by different signal detection devices.

[0091] Step 204: Determine the railway location based on the train location information in the train operation parameters.

[0092] Specifically, train operating parameters include a series of operational data for the train where the signal detection equipment is located, including but not limited to the train's current position, current speed, route, and train signal parameters acquired through interaction between the train's CIR equipment and the GSM-R network system. In this step, the train's current position is used as the train position information in the train operating parameters. The control platform can determine the train's position on the railway route, that is, the railway location corresponding to the corresponding railway signal parameters. The control platform then analyzes the railway signal strength or quality at this railway location.

[0093] Step 206 : Analyze the railway signal parameters and the train signal parameters in the train operation parameters according to different railway locations to confirm the railway signal detection result.

[0094] Specifically, as trains continue to operate, their train locations, as reflected in their operating parameters, change. Therefore, the acquired railway signal parameters can be categorized based on the railway location, allowing for alignment of the railway signal parameters at each train's location. This allows for signal analysis at each railway location. Wireless network signals, such as GSM-R network signals, are analyzed at each railway location, and the analysis results for each location are summarized to yield railway signal detection results.

[0095] Furthermore, in an exemplary embodiment, step 206 includes steps 302 to 304. In which:

[0096] Step 302: Determine the railway signal at the railway location based on the railway signal parameters and train signal parameters at the same railway location.

[0097] The train operation parameters include the current position of the train, the current speed of the train, the running route of the train, and the train signal parameters obtained by the interaction between the CIR equipment on the train and the GSM-R network system.

[0098] Specifically, the corresponding railway signal parameters and train signal parameters are divided according to different railway locations to obtain the railway signal parameters and train signal parameters uploaded by different trains at different times at that railway location. For example, if the train location information in the train operation parameters of a signal detection device indicates that the train passed through the railway location at 9:00, the corresponding railway signal parameters are the railway signal parameters and train signal parameters uploaded by the train at 9:00. If another train passes through the railway location at 10:00, the different times are used as markers, and the signal quality at the railway location at 9:00 and the signal quality at the railway location at 10:00 are recorded respectively. These are analyzed separately to distinguish the fluctuations of the railway signal over time.

[0099] After distinguishing the corresponding time of the railway signal parameters, the railway signal parameters and the train signal parameters will be comprehensively analyzed. For example, the wireless network signal strength in the railway signal parameters and the wireless network signal strength in the train signal parameters will be compared with the preset network signal strength reference value respectively. When one of the two comparison results does not reach the reference value, it is judged that the signal strength is poor. When both comparison results reach the reference value, it is judged that the signal strength meets the standard, and it is determined that the railway signal at the railway location is normal.

[0100] Furthermore, the variance of the wireless network signal strength obtained in different time periods can be calculated or the dispersion analysis can be performed. When the changes in the strength of all wireless network signals are less than the set fluctuation threshold, the railway signal at the railway location is considered to be stable; when all signal strengths are greater than the network signal strength baseline value, the railway signal at the railway location is considered to meet the standard.

[0101] By analyzing the railway signal parameters and train signal parameters at different times as described above and combining the analysis results of each time period, it is possible to determine whether the railway signal at the railway location is stable and whether the signal strength meets the standard, which is used as the railway signal at the railway location.

[0102] Furthermore, when an abnormality is detected in the railway signal, it is possible to distinguish whether the abnormality is in the base station or in the train. In an exemplary embodiment, step 302 includes steps 402 to 406.

[0103] Step 402 : Determine the railway network quality of the railway location based on the railway signal parameters and the train signal parameters at the same railway location.

[0104] In the aforementioned process of analyzing the railway signal parameters and train signal parameters, the result of determining whether the railway signal at the railway location is stable and whether the signal strength meets the standard will be used as the railway network quality at the railway location.

[0105] If the railway network quality at a railway location is normal, that is, if the wireless network signal strength is greater than or equal to the network signal strength baseline, the railway network quality at that railway location is considered normal. Furthermore, if the wireless network signal strength is greater than a set fluctuation threshold, the railway network quality at that railway location can be additionally marked as unstable. If the wireless network signal strength is less than or equal to the set fluctuation threshold, the railway network quality at that railway location can be additionally marked as stable.

[0106] Step 404 , when there is an abnormality in the railway network quality at the railway location, the railway signal parameters on the same train are compared with the train signal parameters in the train operation parameters to confirm the abnormality category.

[0107] If the railway signal is unstable or the signal strength does not meet the standard, that is, if the wireless network signal strength exceeds the set fluctuation threshold or is less than the network signal strength baseline, it can be considered that the railway network quality at the railway location is abnormal. In this case, the control platform can further analyze whether the anomaly is a network base station anomaly or a train data collection anomaly to determine the anomaly type.

[0108] Specifically, train signal parameters acquired simultaneously on the same train are compared with railway signal parameters, and the train signal parameters are analyzed using the railway signal parameters as a benchmark. Anomalies include train acquisition anomalies and network base station anomalies. When the deviation between the train signal parameters and the railway signal parameters is greater than a set deviation threshold, it is considered that the train has an acquisition anomaly. When the deviation between the train signal parameters and the railway signal parameters is less than or equal to the set deviation threshold, it is considered that the train has no acquisition anomaly and the anomaly is due to a network base station anomaly.

[0109] Step 406 : Determine the railway signal at the railway location based on the railway network quality and the anomaly category.

[0110] After determining the anomaly category, the railway network quality is adjusted. For example, if the anomaly category is determined to be a train data collection anomaly, the train with the anomaly is identified as such and the railway network quality is adjusted to normal. If the anomaly category is determined to be a network base station anomaly, nearby base stations are identified as such and the railway network quality at that railway location is maintained as abnormal. The identification information and the updated railway network quality are used as the final railway signal for that railway location.

[0111] In this embodiment, during the process of detecting railway signals, by comparing train signal parameters and railway signal parameters, the abnormality categories are distinguished and the source of the signal abnormality is accurately located, so that the obtained railway signal is more accurate and reliable, and the staff can quickly locate the cause of the abnormality and accurately maintain the railway network.

[0112] Step 304 , summarizing the railway signals at each railway location to determine a railway signal detection result.

[0113] Specifically, after performing the aforementioned analysis on the data at each railway location, the railway signal at each railway location can be obtained. The control platform can then aggregate the railway signals, for example, by labeling each railway location based on a railway route map and recording the railway signal at each railway location. The resulting aggregated data packet or display content serves as the final railway signal detection result.

[0114] Furthermore, the railway signal detection results can be output on a display interactive device, so that staff can conveniently check the railway signal status, detect network anomalies in a timely manner, and repair base stations or trains in a timely manner.

[0115] The above-mentioned railway signal detection method obtains signal detection data uploaded by different signal detection devices, determines the railway location based on the train location information in the train operation parameters, and analyzes the railway signal parameters and the train signal parameters in the train operation parameters according to the different railway locations to confirm the railway signal detection results. By performing railway signal detection and analysis based on the train signal parameters and the railway signal parameters, real-time detection and analysis are achieved, improving the reliability of railway signal detection.

[0116] Furthermore, by understanding the network status of the GSM-R system in real time, this solution can predict faults in advance or initiate maintenance in a timely manner when a fault occurs, reducing the time of railway operation suspension caused by network failures, improving railway transportation efficiency and enhancing safety.
