[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0043] As can be seen from the background technology, at present, the degree of digitization of outdoor equipment is low, the detection content is single, and most outdoor sensors use modulation or analog signal transmission, resulting in limited transmission distance. In addition, indoor and outdoor infrastructure relies on cable electrical connections, which has high construction costs and is difficult to open in sections, integrate and debug, and upgrade. The level of intelligence and digitization of trackside equipment is low, the monitoring and diagnostic methods are imperfect, and fault location is difficult. At the same time, redundant configuration of outdoor sensors is difficult to achieve, further increasing construction costs.

[0044] Therefore, an embodiment of the present invention provides an axle counting system and method. This axle counting system significantly simplifies the station-level signal equipment by optimizing the existing axle counting architecture, and streamlines the entire system into two main parts: the axle counting center host and the axle counting trackside equipment. The axle counting center host is responsible for receiving the axle counting section information from the trackside axle counting equipment, and performing data processing and status evaluation, and uniformly calculating the occupied or cleared status of the axle counting sections of the entire line. Such a design not only improves the accuracy and reliability of the axle counting equipment, but also promotes the overall intelligence and digitalization of the signal system. By introducing advanced digital technology and algorithms, the system can achieve real-time monitoring and intelligent diagnosis of axle counting equipment, thereby further improving the safety and operational efficiency of the rail transit system.

[0045] See also Figure 1 , showing a first schematic diagram of an axle counting system provided by an embodiment of the present invention.

[0046] It should be noted that the axle counting system is specifically based on the "trackside-center" two-level architecture. The "trackside-center" two-level architecture is a system architecture used in the field of urban rail transit, which usually includes the unified management of the central cloud platform and the station edge cloud. This architecture aims to improve the operational efficiency, safety and reliability of the system while reducing maintenance costs and system complexity.

[0047] The axle counting system includes at least two axle counting central devices 100 and a plurality of axle counting trackside devices 200 .

[0048] It should be noted that the train track is divided into a plurality of axle counting sections in advance, and each axle counting section includes a plurality of axle counting points.

[0049] It can be understood that each axle counting trackside device 200 is used to monitor information of multiple axle counting points in an axle counting section.

[0050] Specifically, each axle counting center device 100 is connected to all axle counting trackside devices 200 via redundant optical fiber channels (such as Figure 1 Fiber A and fiber B are shown connected.

[0051] It should be noted that the axle counting center device 100 is arranged in a control center (such as Figure 1The axle counting trackside equipment 200 is arranged beside the track (such as Figure 1 “Trackside” as shown).

[0052] It can be understood that the axle counting center device 100 is specifically an axle counting center host, which adopts a 2x2-take-2 safety platform design. The axle counting system is provided with two axle counting center hosts, for example Figure 1 As shown, they are the Axle Counter Center Main Unit Series I and the Axle Counter Center Main Unit Series II respectively.

[0053] It should be noted that the axle counting center device 100 adopts a 2x2-out-of-2 safety platform design, which mainly improves the redundancy and reliability of the system through dual host redundant configuration, ensuring that even if one host fails, the other host can continue to work, ensuring the continuity and stability of the system. This design can quickly isolate faults and realize automatic switching, avoiding single point failures from affecting system operation, while supporting flexible expansion and improving the adaptability of the system. In addition, the redundant host configuration eliminates the need for downtime during maintenance, reducing operation and maintenance risks and maintenance costs. Overall, the 2x2-out-of-2 design significantly enhances the reliability, security and fault response capabilities of the system.

[0054] Specifically, the axle counting center device 100 is used to receive the axle counting section information sent by all axle counting trackside devices 200, calculate the occupied state or cleared state of each axle counting section according to the axle counting section information, and output it.

[0055] That is to say, the axle counting center device 100 receives information on all axle counting points on the entire track line sent by multiple axle counting trackside devices 200 through redundant optical fiber channels, performs data processing and status evaluation, and simultaneously calculates the occupancy status or clearance status of multiple axle counting sections on the entire track line, and transmits it to the upper-level device through the Railway Transport Intelligent Scheduling Protocol (RSSP-I protocol).

[0056] Specifically, the axle counting trackside equipment 200 is used to detect wheel signals of train wheels passing through the axle counting section, calculate the number of axles, mark the number of axles and wheel signals as axle counting section information, and transmit them to the axle counting center equipment 100 .

[0057] In combination with the embodiments of the present invention Figure 2 The contents shown here describe the structure of the axle counting trackside equipment 200 in detail.

[0058] First, the axle counting trackside device 200 is set beside the track. Each axle counting trackside device 200 detects information of multiple axle counting points in an axle counting section. It can be understood that the area where an axle counting trackside device 200 is set is called a data collection area.

[0059] Specifically, the axle counting trackside equipment 200 includes: an optical-to-electrical hub (i.e., an optical-to-electrical hub), a plurality of axle counting trackside control units, and a plurality of axle counting sensors.

[0060] The optical-to-electrical concentrator is connected to all axle counting trackside control units. It should be noted that the optical-to-electrical concentrator is also used to supply power to the axle counting sensors and the axle counting trackside control unit 202 .

[0061] In some embodiments, Figure 2 As shown in the “power supply access”, the optical-to-electrical hub and all axle-counting trackside control units are also connected to an external power supply device.

[0062] It is understandable that the reason why the optical-to-electrical hub and the axle counting trackside control unit are connected to the external power supply equipment is to ensure stable power supply, achieve redundant design, facilitate maintenance and expansion, and improve system flexibility.

[0063] Specifically, each axle counter trackside control unit is connected to a number of axle counter sensors, such as Figure 2 As shown, each axle counter trackside control unit is connected to two or more axle counter sensors, and the specific number of connections depends on the actual situation and is not specifically limited here.

[0064] It should be noted that the axle counter sensor is configured in a redundant manner, that is, two mutually redundant axle counter sensors can be set at the same axle counter point, for example, Figure 3 As shown (such as J1 to J6), the axle counter sensors are arranged on both sides of two rails in the track, or, are arranged on the same side of the two rails (when specifically arranged, a preset safety distance is maintained between every two axle counter sensors).

[0065] It should be noted that in the axle counting system, when a sensor fails, the system will intelligently switch to another sensor and use its information to make an axle overshoot judgment to ensure the normal operation of the axle counting. This design not only enhances the redundancy and fault tolerance of the system, improves safety and reliability, but also reduces maintenance costs and increases the flexibility and scalability of the system. In addition, the multi-sensor configuration also improves the accuracy of data processing and facilitates fault diagnosis and prediction, thereby optimizing maintenance and operational efficiency while ensuring the safe operation of trains.

[0066] It is understood that the axle counter sensor is used to detect the wheel signal of the train wheel passing through the axle counting point in the axle counting section. Specifically, the axle counter sensor works in an electrical detection mode. When a metal wheel passes over the sensor, the wheel disturbs the magnetic field near the sensor, causing the magnetic field to change. The sensor detects the passage of the wheel by detecting this magnetic field change. This technology can accurately identify the movement of the wheel, providing important safety protection for railway transportation and other occasions.

[0067] Specifically, the axle counting trackside control unit is used to calculate the number of axles of the train wheels passing through the axle counting sensor according to the wheel signals. In other words, the axle counting trackside control unit analyzes and processes these wheel signals to calculate the number of axles of the train wheels passing through the axle counting sensor.

[0068] This design enables the axle counting system to accurately monitor the number of axles on the train, and then determine the integrity of the train and the occupancy status of the track section, which is crucial to ensure the safety of railway transportation. In this way, the axle counting trackside control unit improves the reliability of the system and ensures the safety and efficiency of train operation.

[0069] Specifically, the optical-to-electrical concentrator is used to mark the wheel signal and the number of axles as axle counting section information, and transmit it to the axle counting central device 100. That is, the number of axles calculated by the axle counting trackside control unit of the optical-to-electrical concentrator and the wheel signal detected by the axle counting sensor are marked as axle counting section information, and transmitted to the axle counting central device 100 through a redundant optical fiber channel.

[0070] In combination with the embodiments of the present invention Figure 4 The content shown provides a detailed explanation of the composition of the axle counting trackside control unit.

[0071] Specifically, the axle counter trackside control unit includes: at least two power supply and communication integrated modules (such as Figure 4 The power supply communication integrated module A and the power supply communication integrated module B shown in the figure), two trackside control modules (such as Figure 4 The shown trackside control module I series (main) and trackside control module II series (backup) and multiple signal processing modules.

[0072] It is understandable that the trackside control module also adopts a 2x2-out-of-2 architecture, which significantly enhances the reliability, safety and fault response capabilities of the system. The trackside control module establishes communication with the signal processing module via a bus.

[0073] Specifically, the input end of the integrated power supply and communication module is connected to the optical-to-electrical hub via a power line. The power carrier technology is used to realize co-line transmission of power supply and communication, saving the amount of cables.

[0074] It should be noted that power carrier is a technology used to transmit data. It can use power lines as signal transmission media, load data signals into the power lines, and extract the data signals at the receiving end.

[0075] Specifically, the output end of the power supply and communication integration module is connected to the trackside control module and the signal processing module respectively. The trackside control module is connected to all signal processing modules, and the trackside control module establishes a secure communication connection with the axle counting center device 100 through the power supply and communication integration module and the railway transportation intelligent scheduling protocol (RSSP-I protocol).

[0076] For example Figure 4 As shown, the power supply communication integration module A is connected to the trackside control module system I (main) and the trackside control module system II (standby) through the data bus A; the power supply communication integration module B is connected to the trackside control module system I (main) and the trackside control module system II (standby) through the data bus B; the power supply communication integration module A is redundantly connected to all signal processing modules through the monitoring and maintenance bus; the power supply communication integration module B is redundantly connected to all signal processing modules through the monitoring and maintenance bus. The trackside control module system I (main) and the trackside control module system II (standby) communicate with each other and share data.

[0077] It can be understood that each signal processing module is specifically connected to an axle counter sensor (or two axle counter sensors) via a tail cable.

[0078] Specifically, the signal processing module is used to power the axle counting sensor, receive the wheel signal sent by the axle counting sensor, and calculate the number of axles of the train wheels passing through the axle counting sensor according to the wheel signal. The trackside control module is used to collect the wheel signals and axle numbers sent by all signal processing modules, mark them as axle counting section information, and transmit them to the axle counting center device 100.

[0079] In practical applications, the integrated power supply and communication module is used to power the trackside control module and the signal processing module.

[0080] See also Figure 4 As shown, the axle counter trackside control unit also includes an axle counter monitoring module, wherein the axle counter detection module is connected to all signal processing modules.

[0081] It should be noted that the axle counter monitoring module is used to monitor all wheel signals and the number of axles and record them in real time.

[0082] In the embodiment of the present invention, by adopting long-distance reliable power supply and communication technology, the simplification of station-level signal equipment is achieved, and a "trackside-center" two-level safety coordination architecture is constructed. This architecture not only improves the reliability of the system, but also enables the trackside equipment to transmit data to the indoor through communication through the trackside axle counting function, significantly improving the digital level of the axle counting trackside. The dual redundant design of the axle counting sensor further enhances the stability and safety of the system, ensures stable operation in key applications, and improves the scalability of the detection content of the trackside equipment, so that the system can adapt to changing needs and environments.

[0083] The embodiments of the present invention have a number of significant advantages: First, the degree of digitization of outdoor equipment is improved, making the detection content easier to expand and enhancing the flexibility of the system. Secondly, the communication between the axle counting trackside equipment and the axle counting center host adopts a network mode, which is not limited by the transmission distance, and improves the convenience and coverage of communication. In addition, the "trackside-center" two-level architecture of the embodiment of the present invention facilitates centralized opening and integrated debugging, and simplifies the operation process. By reducing the use of cables, the present invention reduces construction costs. In terms of monitoring and diagnosis, the present invention provides a complete means to accurately locate faults and improve the maintenance efficiency of the system. Finally, the dual redundant design of the outdoor sensor significantly improves the reliability of the system and ensures stable operation in critical applications.

[0084] In summary, the embodiments of the present invention not only reduce costs but also improve the efficiency and reliability of the system through intelligent and digital innovations, bringing significant performance improvements to the rail transit system.

[0085] Corresponding to the axle counting system proposed in the above embodiment of the present invention, see Figure 5 , shows a flow chart of an axle counting method proposed in an embodiment of the present invention, which is applicable to the above-mentioned axle counting system. The method comprises:

[0086] Step S501: Utilize multiple axle counting trackside devices to detect wheel signals of train wheels passing through the axle counting section, calculate the number of axles, mark the number of axles and wheel signals as axle counting section information, and transmit them to the axle counting center device.

[0087] It should be noted that each axle counting trackside device corresponds to an axle counting section, and the track includes multiple axle counting sections.

[0088] In the specific implementation of step S501, multiple axle counting trackside devices are used to integrate the collected wheel signals and the calculated axle numbers to form detailed axle counting section information, including but not limited to the axle number of the train, the speed of the train, the direction and other parameters.

[0089] Step S502: using the axle counting center equipment to receive the axle counting section information sent by all axle counting trackside equipment, and calculating the occupied state or cleared state of each axle counting section according to the axle counting section information and outputting it.

[0090] In the specific implementation of step S502, the axle counting center device receives the axle counting section information sent by each axle counting trackside device. By analyzing this information, the axle counting center device can calculate the occupied state or cleared state of each axle counting section and output the corresponding result.

[0091] Understandably, this process ensures the safety and efficiency of railway transportation as it enables real-time monitoring of train operations in various sections, thus providing accurate data support for train scheduling and safety management.

[0092] In the embodiment of the present invention, intelligent monitoring and diagnosis means are adopted in two main parts, namely the axle counting center host and the axle counting trackside equipment, so as to improve the maintenance efficiency, enhance the efficiency and reliability of the rail transit system, and reduce the cost.
