Abstract

[0002] In urban rail transit systems, the stable operation of the onboard Automatic Train Protection (ATP) system is highly dependent on the accuracy of its speed measurement function, which in turn relies entirely on real-time data acquisition from the speed sensor. To ensure that the speed sensor can continuously and stably provide reliable train speed information, regular and necessary inspections are essential. Among these inspections, disconnection inspection is particularly important because it is directly related to the continuity and integrity of sensor data. However, the current industry-wide use of hardware detection methods involves indirectly determining whether a disconnection is present by monitoring the current value of the speed sensor's power supply circuit. While this method can identify some disconnections to a certain extent, it is prone to false alarms in the face of strong external electromagnetic interference and frequent changes in speed sensor models. Furthermore, when a speed sensor disconnects due to an internal physical fault, this method often fails to detect it promptly and accurately, posing a potential risk to the safe operation of the train.

[0031] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.
[0032] The following describes a train sensor fault detection method, a computer-readable storage medium, a train sensor fault detection device, and a train according to embodiments of the present invention with reference to the accompanying drawings.
[0033] Figure 1 4 is a flow chart of a method for detecting a fault of a train sensor according to an embodiment of the present invention.
[0034] Specifically, in some embodiments of the present invention, the train is provided with a plurality of sensors, such as Figure 1 As shown, the train sensor fault detection method includes:
[0035] S101, obtaining the train status information and the collected information of each sensor.
[0036] Specifically, in this embodiment, the status information includes the start-up operation process, the operation process, and / or the parking process. These three status information comprehensively cover the entire cycle of the train from stationary to moving and then to stopping. During the entire cycle of the train's operation, the system will continue to read and collect information from each sensor. The system can obtain the train's status information through on-board monitoring equipment. In addition, the present invention does not require specific limitations on the method of obtaining the train's status information. For example, it is also possible to communicate with the equipment on the train through remote communication technology to obtain the train's operating status information in real time. It should be noted that when the sensor is a speed sensor, the collected information is speed information.
[0037] S102: Determine abnormal information in the collected information according to the status information.
[0038] Specifically, in this embodiment, when the status information is the starting operation process, and the collected information collected by the sensor indicates that the train's travel speed is continuously zero, the collected information is determined to be abnormal information; when the status information is the operation process, and the collected information collected by the sensor indicates that the train's travel speed is zero, the collected information is determined to be abnormal information; when the status information is the parking process, and at least one corresponding collected information collected by at least one sensor among the multiple sensors indicates that the train's travel speed is zero, and other collected information collected by other sensors indicates that the train's travel speed is non-zero, then at least one collected information is determined to be abnormal information.
[0039] S103: Determine a collection state of a sensor for collecting abnormal information according to the collected information and / or the actual running speed of the train.
[0040] Specifically, in this embodiment, when the collected information collected by the sensor indicates that the train's speed is continuously zero, the collected information is determined to be abnormal information. When the collected information indicates that the length of time the train's speed is continuously zero reaches a first preset length of time, it is determined that the sensor that collects the abnormal information has a collection failure. When the status information is the running process, and the collected information collected by the sensor indicates that the train's speed is zero, the collected information is determined to be abnormal information. When the collected information indicates that the train's speed is continuously zero reaches a first preset length of time, it is determined that the sensor that collects the abnormal information has a collection failure. When the status information is the running process, and the collected information collected by the sensor indicates that the train's speed is zero, the collected information is determined to be abnormal information. When the collected information indicates that the train's speed is continuously zero, the collected information is determined to be abnormal information. When the speed drops to zero within the second preset time period, it is determined that the sensor collecting abnormal information has a collection failure; when the status information is a parking process, when at least one corresponding collection information collected by at least one sensor among multiple sensors indicates that the train's speed is zero, and other collection information collected by other sensors all indicate that the train's speed is non-zero, then at least one collection information is determined to be abnormal information; when the actual speed of the train is less than the preset speed, at least one corresponding collection information collected by at least one sensor among multiple sensors indicates that the train's speed continues to be zero for a third preset time period, and other collection information collected by other sensors still indicates that the train's speed is non-zero, it is determined that at least one sensor collecting abnormal information has a collection failure.
[0041] Furthermore, in some embodiments of the present invention, when the status information is about the start-up operation process, abnormal information in the collected information is determined based on the status information, including: when the collected information collected by the sensor indicates that the train's travel speed is continuously zero, determining that the collected information is abnormal information.
[0042] Specifically, in this embodiment, when the sensor is a speed sensor and the status information is the start-up operation process, the speed collected by the speed sensor will be converted from a zero value to a non-zero value as the train starts to run. If the collected information collected by the speed sensor indicates that the train's running speed continues to be zero, the collected information is determined to be abnormal information.
[0043] Furthermore, in some embodiments of the present invention, the collection status of the sensor that collects abnormal information is determined based on the collected information and / or the actual running speed of the train, including: when the collected information indicates that the duration for which the train's running speed has been continuously zero reaches a first preset duration, it is determined that the sensor that collects abnormal information has a collection failure.
[0044] Specifically, in this embodiment, the first preset time length can be two minutes, five minutes or ten minutes. In addition, the present invention may not impose a specific limitation on the value of the first preset time length. When the sensor continuously collects and feeds back the train speed as zero, and the duration reaches the first preset time length, it is determined that the sensor collecting abnormal information has a collection failure.
[0045] Furthermore, in some embodiments of the present invention, when the status information is an operating process, abnormal information in the collected information is determined based on the status information, including: when the collected information collected by the sensor indicates that the train's travel speed is zero, determining that the collected information is abnormal information.
[0046] Specifically, in this embodiment, when the sensor is a speed sensor and the status information is the running process, the train is in operation at this time, and the speed collected by the speed sensor should be a non-zero value. If the collected information collected by the speed sensor indicates that the train's running speed is zero, then the collected information is determined to be abnormal information.
[0047] Furthermore, in some embodiments of the present invention, the collection status of the sensor that collects abnormal information is determined based on the collected information and / or the actual running speed of the train, including: when the collected information indicates that the running speed of the train drops to zero within a second preset time period, it is determined that the sensor that collects abnormal information has a collection failure.
[0048] Specifically, in this embodiment, the second preset time length can preferably be 50 milliseconds. In addition, the present invention may not specifically limit the value of the second preset time length. For example, the second preset time length can also be 40 milliseconds, 55 milliseconds or 60 milliseconds. When the information collected by the sensor indicates that the train's speed drops from a non-zero value to zero within the second preset time, it is determined that the sensor collecting the abnormal information has a collection failure.
[0049] Furthermore, in some embodiments of the present invention, when the status information is a parking process, abnormal information in the collected information is determined based on the status information, including: when at least one corresponding collected information collected by at least one sensor among multiple sensors indicates that the train's travel speed is zero, and other collected information collected by other sensors indicates that the train's travel speed is non-zero, then at least one collected information is determined to be abnormal information.
[0050] Specifically, in this embodiment, when the sensor is a speed sensor and the status information is a stopping process, when the train stops from running, the speeds collected by all speed sensors should be converted from non-zero values to zero values. If at least one corresponding piece of information collected by at least one sensor among the multiple sensors indicates that the train's speed is zero, while the other collected information collected by the other sensors all indicate that the train's speed is non-zero, then at least one piece of collected information is determined to be abnormal information. For example, if there are four speed sensors, and the information collected by one speed sensor indicates that the train's speed is zero, while the information collected by the other three speed sensors all indicate that the train's speed is non-zero, then the collected information indicating that the train's speed is zero is determined to be abnormal information. If the information collected by two of the four speed sensors all indicates that the train's speed is zero, and the information collected by the other two speed sensors all indicates that the train's speed is zero, then the collected information indicating that the train's speed is zero is determined to be abnormal information.
[0051] Furthermore, in some embodiments of the present invention, the collection status of the sensor that collects abnormal information is determined based on the collection information and / or the actual running speed of the train, including: when the actual running speed of the train is less than the preset speed, at least one corresponding collection information collected by at least one sensor among the multiple sensors indicates that the train's running speed has been continuously zero for a third preset time period, and other collection information collected by other sensors still indicates that the train's running speed is non-zero, it is determined that at least one sensor that collects abnormal information has a collection failure.
[0052] Specifically, in this embodiment, when at least one corresponding piece of information collected by at least one sensor among a plurality of sensors indicates that the train's speed is zero, and other pieces of information collected by other sensors indicate that the train's speed is non-zero, then at least one piece of information is determined to be abnormal information. The third preset time period may be two minutes, four minutes, or five minutes, and the preset speed may preferably be 10 km / h. In addition, the present invention may not specifically limit the values of the second preset time period and the preset speed. For example, the preset speed may also be 8 km / h, 15 km / h, or 20 km / h. When the sensors are speed sensors and there are four of them, and the train's speed is less than the preset speed, and the information collected by one of the speed sensors indicates that the duration of the zero speed has reached the third preset duration, and the information collected by the other three speed sensors indicates that the train's speed is non-zero, then it is determined that the speed sensor indicating that the duration of the zero speed has reached the third preset duration has a collection failure. If the information collected by two speed sensors among the four sensors indicates that the duration of the continuous zero speed reaches a third preset duration, and the information collected by the other two speed sensors indicates that the train's speed is non-zero, it is determined that the two speed sensors indicating that the duration of the continuous zero speed reaches the third preset duration have a collection failure.
[0053] Furthermore, in some embodiments of the present invention, the collected information includes fault reporting information, and the method also includes: when the fault reporting information corresponding to multiple sensors all indicates that the sensors have failed, and the collected information corresponding to multiple sensors all indicates that the train's travel speed is zero, the train guidance safety processing is controlled to improve the train's travel safety.
[0054] Furthermore, in some embodiments of the present invention, the multiple sensors include a first speed sensor, a second speed sensor, a third speed sensor and a fourth speed sensor, and the train includes a first ATP system, a first speed measuring board, a second ATP system and a second speed measuring board, wherein the first ATP system is connected to the first speed sensor and the second speed sensor through the first speed measuring board, and the second ATP system is connected to the third speed sensor and the fourth speed sensor through the second speed measuring board.
[0055] Specifically, in this embodiment, Figure 2As shown, multiple sensors include a first speed sensor, a second speed sensor, a third speed sensor and a fourth speed sensor. The first ATP system supplies power, detects faults and collects speed pulses for the first speed sensor and the second speed sensor through the first speed measuring board. The second ATP system supplies power, detects faults and collects speed pulses for the third speed sensor and the fourth speed sensor through the second speed measuring board. The first ATP system can be located at the front part of the train, and the second ATP system can be located at the rear part of the train. The first ATP system and the second ATP system exchange information through the head-to-tail through-line, so that the first ATP system and the second ATP system can both obtain information collected by the first speed sensor, the second speed sensor, the third speed sensor and the fourth speed sensor.
[0056] Furthermore, in some embodiments of the present invention, the acquisition fault includes a line break fault.
[0057] In summary, the train sensor fault detection method according to an embodiment of the present invention obtains train status information and the collected information of each sensor, determines abnormal information in the collected information based on the status information, and then determines that the sensor corresponding to the abnormal information has a collection fault when the sensor meets preset conditions. This improves the accuracy and timeliness of sensor disconnection detection, thereby enhancing train safety.
[0058] Based on the train sensor fault detection method proposed in the aforementioned embodiment of the present invention, the embodiment of the present invention also proposes a computer-readable storage medium, on which a train sensor fault detection program is stored. When the train sensor fault detection program is executed by a processor, the train sensor fault detection method of the aforementioned embodiment of the present invention is implemented.
[0059] According to the computer-readable storage medium of the embodiment of the present invention, the processor executes the fault detection program of the train sensor, which can improve the accuracy and timeliness of sensor disconnection detection, thereby improving the safety of train travel.
[0060] Figure 3 4 is a block diagram of a fault detection device for a train sensor according to an embodiment of the present invention.
[0061] Specifically, in some embodiments of the present invention, the train is provided with a plurality of sensors, such as Figure 3 As shown, the train sensor fault detection device 100 includes an acquisition module 10 , a first determination module 20 and a second determination module 30 .

[0063] In some embodiments of the present invention, the status information includes a startup operation process, an operation process and / or a parking process.
[0064] In some embodiments of the present invention, when the status information is about the start-up operation process, the first determining module 20 is specifically configured to determine that the collected information is abnormal information when the collected information collected by the sensor indicates that the train's running speed is continuously zero.

[0066] In some embodiments of the present invention, when the state information is a running process, the first determining module 20 is specifically configured to determine that the collected information is abnormal information when the collected information collected by the sensor indicates that the running speed of the train is zero.
[0067] In some embodiments of the present invention, the first determination module 20 is further configured to determine that a sensor that collects the abnormal information has a collection failure when the collection information collected by the sensor indicates that the train's speed drops to zero within a second preset time period.
[0068] In some embodiments of the present invention, when the status information is a parking process, the first determination module 20 is specifically used to determine that at least one collected information is abnormal information when at least one corresponding collected information collected by at least one sensor among multiple sensors indicates that the train's travel speed is zero, and other collected information collected by other sensors indicates that the train's travel speed is non-zero.
[0069] In some embodiments of the present invention, the first determination module 20 is also used to determine that at least one sensor that collects abnormal information has a collection failure when the actual speed of the train is less than a preset speed, at least one corresponding collection information collected by at least one sensor among the multiple sensors indicates that the train's speed has been continuously zero for a third preset time period, and other collection information collected by other sensors still indicates that the train's speed is non-zero.
[0070] In some embodiments of the present invention, the collected information includes fault reporting information. When the fault reporting information corresponding to multiple sensors all indicates that the sensors have failed, and the collected information corresponding to multiple sensors all indicates that the train's travel speed is zero, the train is controlled to be directed to safe processing.
[0071] In some embodiments of the present invention, the multiple sensors include a first speed sensor, a second speed sensor, a third speed sensor and a fourth speed sensor, and the train includes a first ATP system, a first speed measuring board, a second ATP system and a second speed measuring board, wherein the first ATP system is connected to the first speed sensor and the second speed sensor through the first speed measuring board, and the second ATP system is connected to the third speed sensor and the fourth speed sensor through the second speed measuring board.

To reduce redundancy, they will not be repeated here.
[0074] In summary, the train sensor fault detection device according to an embodiment of the present invention uses an acquisition module to obtain train status information and collected information from each sensor. A first determination module then determines abnormal information in the collected information based on the status information. Furthermore, a second determination module determines the collection status of the sensor that collected the abnormal information based on the collected information and / or the actual speed of the train. This improves the accuracy and timeliness of sensor disconnection detection, thereby enhancing train safety.
