[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] It should be noted that the following embodiments and features therein may be combined with each other unless they conflict. Furthermore, all other embodiments derived by persons of ordinary skill in the art based on the embodiments in this disclosure without inventive effort are also within the scope of protection of this disclosure.

[0043] It should be noted that various aspects of the embodiments within the scope of the appended claims are described below. It should be apparent that the aspects described herein can be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on this disclosure, it should be understood by those skilled in the art that an aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number of aspects described herein can be used to implement an apparatus and / or practice a method. In addition, other structures and / or functionalities other than one or more of the aspects described herein can be used to implement this apparatus and / or practice this method.

[0044] As an embodiment of the present invention, Figure 1 As shown, a railway vehicle number recognition system is provided, comprising: a radio frequency component, a radio frequency module, a wheel detection module and a main processing module, wherein the radio frequency component is connected to the radio frequency module, and the radio frequency module and the wheel detection module are respectively connected to the main processing module.

[0045] The radio frequency component is used to generate a microwave radiation energy field, receive the signal reflected by the railway freight car tag entering the microwave radiation energy field, and demodulate the reflected signal to form a radio frequency signal.

[0046] The radio frequency module is used to decode the radio frequency signal to obtain a decoded signal carrying the railway freight car tag information, and send the decoded signal to the main processing module.

[0047] In this embodiment, the railway freight car tag information refers to the identity information of each car in the entire train. In actual use, each train car is equipped with an electronic tag on the bottom. This electronic tag stores the car number information of that car, which is the inherent identity information of each car. To obtain the car number information, which includes the vehicle identity information and wheel information, the car number recognition system provided in this embodiment processes the decoded signal of the electronic tag and the trigger signal of the train wheel to identify and obtain the vehicle number information.

[0048] Specifically, the RF component includes an RFID antenna and an RF feeder. The RF feeder is connected to the RFID antenna and the RF module respectively. The RFID antenna generates a microwave radiation energy field. After the train enters the microwave radiation energy field, the electronic tag at the bottom of the car reflects the microwave signal, which is received by the RFID antenna to form an RF signal. The RF feeder receives the RF signal sent by the RFID antenna and sends it to the RF module for processing.

[0049] Among them, the RFID antenna is set between the two sleepers of the railway track and can generate a microwave radiation energy field. After the train enters the microwave radiation energy field, the electronic tag at the bottom of the car reflects the signal. The RFID antenna receives the signal reflected by the electronic tag to form an RF signal and sends the RF signal to the RF feeder. The RF feeder sends the RF signal to the RF module for processing.

[0050] When selecting an RFID antenna, consideration must be given to its size and area. It must be able to be installed in the designated location, ensuring that the range and intensity of the microwave radiation energy field generated are suitable for determining the train's tag information. The RFID antenna must be directional, directing the majority of the radiated energy toward the area where the electronic tag is located, thereby providing the maximum possible radiation signal to the tag chip. The vehicle's direction of travel must also be considered to maximize the success rate of obtaining the train's identity information as the train passes.

[0051] Specifically, after receiving the radio frequency signal sent by the radio frequency feeder, the radio frequency module decodes the radio frequency signal to obtain a decoded signal of the carriage tag information, and sends the decoded signal to the main processing module.

[0052] Specifically, the wheel detection module is used to collect wheel triggering signals when the vehicle wheels trigger wheel sensors installed on the railway tracks, and send the wheel triggering signals to the main processing module.

[0053] In this embodiment, the wheel detection module includes at least a plurality of magnetic steel wheel sensors and a sensor data acquisition module. The specific arrangement of the wheel sensors can be referred to Figure 2 As an embodiment, four magnetic steel wheel sensors can be set along the extension direction of the railway track. Among them, the two magnetic steel wheel sensors located at the two ends of the railway track (such as 1# and 4# in the figure) are vehicle identification sensors, which are used to determine whether there are vehicles passing in two different driving directions. The two magnetic steel wheel sensors in the middle (such as 2# and 3# in the figure) belong to the same axle identification sensor group, which is used to identify the number of wheels and the wheelbase between the wheels in the same carriage.

[0054] The magnetic wheel sensor is a proximity switch (magnetic steel) secured to the rail using a mounting plate. It contains two magnets with opposite polarity. When a train wheel passes over the magnet, the magnetic field generated by the magnet is disrupted, as the wheel is typically made of ferromagnetic material. This interference causes a change in the magnetic field. The magnetic sensor contains components that detect changes in the magnetic field (such as Hall effect elements or magnetoresistive elements). These components generate an electrical signal when the magnetic field changes due to the wheel's passage.

[0055] The sensor data acquisition module is used to collect signals from magnetic sensors triggered by wheels. These wheel trigger signals include at least information about whether a wheel has passed, the time the vehicle passed each sensor, the vehicle's direction and speed, the number of wheel axles, the number of vehicles, and the wheelbase of each car. The sensor data acquisition module transmits the collected wheel trigger signals to the main processing module for processing to obtain wheel information.

[0056] In the axle determination sensor group of this embodiment, two magnetic steel wheel sensors with a small spacing are set to identify and determine the wheel axle. This arrangement has the following advantages:

[0057] When two sensors are in close proximity, they are triggered almost simultaneously by the same wheel. By comparing the signals from these two sensors, the exact position of a wheel can be determined more accurately. If only a single sensor is used, various factors such as train speed fluctuations and sensor sensitivity may lead to inaccurate detection.

[0058] In multi-axle trains, especially when the distance between axles is short, two closely spaced sensors can help clearly distinguish the signals from adjacent wheels, allowing accurate determination of the position of each axle. This is because even very close wheels will experience a slight time difference when passing between the two sets of sensors. These time differences can be used to effectively identify each wheel and calculate the distance between the axles.

[0059] When installing the magnetic wheel sensor, ensure that the upper surface of the magnet is between (35 and 40) mm and the rail surface. The specific height depends on the actual situation. In places with higher speeds, the distance between the upper surface of the magnet and the rail surface can be appropriately increased. On the contrary, the distance between the upper surface of the magnet and the rail surface can be reduced, but the minimum distance cannot be less than 30 mm.

[0060] Specifically, the main processing module is used to process the decoding signal and the wheel trigger signal to obtain the vehicle number information. The vehicle number information includes the railway freight car label information obtained by the main processing module based on the decoding signal and the wheel information obtained by the main processing module based on the wheel trigger signal. The railway freight car label information at least includes the vehicle number data and vehicle model data of each carriage, and the wheel information at least includes one or more of the vehicle's driving direction, the time the wheel passes through the sensor, the number of vehicle axles, the number of vehicles, the vehicle speed, and the wheel wheelbase. The main processing module is also used to send the vehicle number information to the upper computer, which is one or more of an automatic track scale, an overload and unbalanced load detection device, and a railway freight car loading status video monitoring system. The vehicle number information is associated with one or more of the weighing information, overload and unbalanced load status information, and railway freight car loading status video monitoring information output by the upper computer and generates a train data networking message. The train data networking message can be generated on the vehicle number recognition system side or on the upper computer side.

[0061] The vehicle number recognition system of the present invention includes a radio frequency component, a radio frequency module, a wheel detection module, and a main processing module. The main processing module can process the decoding signal output by the radio frequency module and the wheel trigger signal output by the wheel detection module to obtain vehicle number information. The vehicle number information includes not only the identity tag information of each carriage of the railway freight car, but also the wheel information of each carriage; the wheel information can also include information such as the vehicle's direction of travel, wheelbase, number of vehicles, and speed. Therefore, the vehicle number recognition system of the present invention can provide real-time vehicle information of traveling trains, especially high-speed trains, and can accurately match the measurement, detection, and monitoring information output by the host computer, providing an accurate and real-time data foundation for intelligent management.

[0062] As another embodiment, Figure 6 As shown, the vehicle number recognition system also includes a data storage module and a clock unit, wherein:

[0063] The data storage module is used to store the vehicle number information obtained by the main processing module and resend the vehicle number information that was not successfully sent after the communication between the railway vehicle number recognition system and the host computer is interrupted and then restored.

[0064] The clock unit is used to configure the corresponding timestamp for the car number information of each car, so as to establish an association with the measurement, detection and monitoring information output by the host computer.

[0065] Specifically, the clock unit provides an accurate timestamp for the car number information of each car. Therefore, after the car number information is sent to the host computer, other information of the car (such as weight information, overload information, video surveillance information) can be accurately matched with the car number information based on the time information, thereby improving the accuracy of the final generated measurement, detection and monitoring data.

[0066] As another embodiment, Figure 6 As shown, the vehicle number recognition system also includes: a communication component, which is connected to the main processing module and is used to provide at least one communication port. The at least one communication port realizes communication between the main processing module and the host computer according to a preset communication protocol and sends the vehicle number information to the host computer.

[0067] Specifically, the communication ports include at least one or more of an RS232 communication port, an RS485 communication port, a CAN bus communication port, and a TCP / IP network communication port, enabling communication with one or more of an automatic track scale, an overload and unbalanced load detection device, and a railway freight car loading status video monitoring system. When the communication ports include a TCP / IP network communication port, the port serves as a separate network interface. The main processing module transmits vehicle number information in real time to a designated host computer, such as a designated server, via the TCP / IP network communication port for statistical purposes by the freight management department.

[0068] In this embodiment, when the main processing module transmits vehicle license plate information to the host computer in real time, this data transmission is typically wireless, so there is a possibility that the communication link may be disturbed and unavailable. When a communication link problem occurs, the vehicle license plate information that the main processing module cannot send can be temporarily stored in the storage unit. After the communication link is restored, the unsuccessful vehicle license plate information can be uploaded again. At the same time, the data storage module can also store the real-time collected vehicle license plate information for long-term storage, facilitating subsequent traceability requirements.

[0069] As another embodiment, the vehicle number recognition system transmits vehicle number recognition information in real time to a host computer. The host computer can be one or more of the following: an automatic track scale, an overload and unbalanced load detection device, and a railway freight car loading status video monitoring system. The vehicle number information is associated with one or more of the weighing information, overload and unbalanced load status information, and railway freight car loading status video monitoring information output by the host computer to generate a train data network message. This allows the vehicle number information to be matched and combined in real time with other types of train information detected by other railway freight car detection and metering equipment to form a complete and accurate data message at the same time as the train passes, effectively avoiding vehicle number misalignment and erroneous data issues, and improving the reliability of railway vehicle detection data.

[0070] Specifically, such as Figure 3As shown, the host computer is an automatic track scale. An automatic track scale is a measuring device used to weigh railway freight cars. It is used for dynamic or static weighing of moving trains or parked vehicles. It can accurately measure the weight of individual cars, the entire train, and axle loads.

[0071] When the host computer is an automatic track scale, the automatic track scale includes a metering module, which includes a weighing unit, a vehicle number label real-time receiving unit, a wheel sensor data real-time receiving unit, a matching unit, and a vehicle data generation unit. The metering module can match and combine the vehicle number information of each car with the car weight and axle weight information to generate a train data network message. Among them, the weighing unit is used to obtain the cargo load measurement information of each car, and the cargo load measurement information at least includes the weight information of each car; the vehicle number label real-time receiving unit is used to receive the label information of each car sent by the main processing module in real time; the wheel sensor data real-time receiving unit is used to receive the wheel information of each car sent by the main processing module in real time; the matching unit is used to match the label information, wheel information, and weight information of each car in real time based on the timestamp generated by the clock unit; the vehicle data generation unit is used to associate the cargo load measurement information, label information, and wheel information of each car based on the timestamp generated by the clock unit and generate a train data network message.

[0072] Specifically, such as Figure 4 As shown, the host computer is an overload and unbalanced load detection device, which is used to detect whether there is a problem of improper cargo loading on the railway freight car, including overload (too heavy), underload (too light), and unbalanced load (uneven weight distribution).

[0073] When the host computer is an overload and unbalanced load detection device, the overload and unbalanced load detection device includes an overload and unbalanced load detection module for detecting the overload and unbalanced load status information of the vehicle. The vehicle data generation unit matches and combines the vehicle number information of each carriage with the carriage overload, underload and unbalanced load information to generate a train data networking message.

[0074] Specifically, such as Figure 5 As shown, the host computer is a railway freight car loading status video monitoring system. This system is designed to ensure the safety and compliance of railway freight car loading through video monitoring and intelligent video analysis. The system can monitor cargo loading conditions in real time, identify potential problems such as overloading, uneven loading, and cargo shifting, and provide timely warnings and more intuitive carriage image information.

[0075] When the host computer is a railway freight car loading status video monitoring system, the railway freight car loading status video monitoring system includes a railway freight car loading status video monitoring module, which is used to capture vehicle images in a preset time period before and after the wheel sensor is triggered. The vehicle data generation unit matches and combines the vehicle number information of each carriage with the image information of the carriage to generate a train data networking message.

[0076] Based on this, the vehicle number information can be associated with one or more of the weighing information, overload and unbalanced load status information, and railway freight car loading status video monitoring information, and then a train data networking message integrating the vehicle number information, weighing information, overload and unbalanced load status information, and railway freight car loading status video monitoring information can be generated to reflect the overall vehicle information of the freight car, so as to improve the accuracy and intelligence of railway freight monitoring work based on vehicle number identification data messages.

[0077] As another embodiment, the vehicle number recognition system also includes a verification module for generating the entire train number data based on the vehicle number information of each carriage, and verifying the vehicle number information output by the vehicle number recognition system and the vehicle train data networking message generated by associating the measurement, detection and monitoring information output by the upper computer, so as to further improve the reliability of the detection data of the truck detection equipment.

[0078] Specifically, the verification module in this embodiment can be set at the vehicle number recognition system end, or at the host computer end. The verification module can be based on the time information carried in the vehicle number information and the relevant identity information of the carriage, and the time information and the relevant identity information of the carriage carried in the carriage information obtained by any form of host computer, to conduct mutual verification, thereby further improving the reliability of the detection data of the truck detection equipment. For example, if the host computer is an overload detection device, the overload detection device can obtain the overload information of each pair of wheels on the carriage, and each pair of wheels corresponds to the same axle, thereby determining the number of axles the carriage has, and even the wheelbase information. This information can be cross-verified with the number of axles and wheelbase information in the vehicle number information.

[0079] As another embodiment, the vehicle number recognition system further includes a buzzer connected to the main processing module and configured to emit a beeping signal based on the vehicle number information obtained by the main processing module. When the buzzer is on, the main processing module will emit a beeping signal when it recognizes the vehicle number information. When the buzzer is off, the main processing module will not emit a beeping signal when it recognizes the vehicle number information. The buzzer provided in this embodiment can provide real-time notification of the vehicle number tag data recognition status.

[0080] As another embodiment, Figure 6As shown, the vehicle number identification system further comprises a display module connected to the main processing module, for displaying the vehicle number information and / or the switch state of the radio frequency component, the switch state of the buzzer and the state of the main processing module sending information to the upper computer.

[0081] Specifically, the display module (i.e. the display screen) is mainly used to display various working states of the vehicle number identification system, and the decoded vehicle number data will be displayed on the display screen when the vehicle number identification is successful. The display screen at least displays whether the radio frequency module is turned on or off, whether the system is in a working state or standby state, and whether the current buzzer is in an on state or an off state, whether the vehicle number data is identified to ring, and the operator can judge the vehicle number tag data reading condition through the sound. The display screen at least displays the vehicle number information sent by the vehicle number identification system to the upper computer and the internal state information of the vehicle number identification system.

[0082] As another embodiment, as shown in Figure 6 The vehicle number identification system further comprises a power module, a temperature control module and a heater control module, wherein,

[0083] The power module supplies power to the radio frequency module, the wheel detection module, the main processing module, the temperature control module and the heater control module; the power module also supplies power to the display module, the buzzer, the data storage module, the clock unit, the verification module and the communication component;

[0084] The temperature control module is connected to the main processing module, for collecting the working temperature of the railway vehicle number identification system;

[0085] The heater control module is connected to the main processing module, for starting the heater to work when receiving the working temperature of the railway vehicle number identification system in the preset low temperature state information sent by the main processing module.

[0086] The temperature control module is used to collect the temperature information inside the railway vehicle number identification system, and according to whether the current temperature is within the preset working temperature range, the heater control module is controlled to perform corresponding heating work. Similarly, a humidity sensor and a fan can be set to cooperate to control the humidity inside the railway vehicle number identification system to be within the preset humidity range, so as to improve the service life of the railway vehicle number identification system.

[0087] According to another aspect of the present application, as shown in Figure 7 An integrated device with railway vehicle number identification and metering detection monitoring functions is provided, which comprises a railway vehicle number identification system and a metering module, the metering module comprises a weighing unit, a vehicle number tag real-time receiving unit, a magnetic steel wheel sensor data real-time receiving unit, a matching unit and a vehicle data generating unit, wherein,

[0088] The weighing unit is used to obtain the cargo load measurement information of each carriage, and the cargo load measurement information at least includes the weight information of each carriage.

[0089] The vehicle number label real-time receiving unit is used to receive the label information of each carriage sent by the main processing module in real time.

[0090] The magnetic steel wheel sensor data real-time receiving unit is used to receive the wheel information of each carriage sent by the main processing module in real time.

[0091] The matching unit is used to perform real-time matching of the label information, wheel information and cargo load measurement information of each carriage based on the timestamp generated by the clock unit.

[0092] The vehicle data generation unit is used to associate the cargo load measurement information, label information and wheel information of each carriage based on the timestamp generated by the clock unit and generate a train data networking message.

[0093] In this embodiment, when a train passes through the integrated device, a train data networking message can be generated that integrates the car number information of each car and the car weight and axle weight information.

[0094] As another embodiment, the integrated device also includes an overload and unbalanced load detection unit for detecting the overload and unbalanced load status information of the vehicle. The vehicle data generation unit is also used to associate the cargo load measurement information, label information, wheel information and overload status information of each carriage and generate a train data networking message.

[0095] In this embodiment, when a train passes through the integrated device, the generated train data networking message includes not only the car number information, car weight, axle weight and other information of each car, but also overload, underload and uneven load information.

[0096] As another embodiment, the integrated device also includes a railway freight car loading status video monitoring module for capturing images of the freight car in a preset time period before and after the magnetic steel wheel sensor is triggered, and associating the vehicle number information with the vehicle image.

[0097] In this embodiment, when a train passes through the integrated device, the train data networking message that can be generated includes not only the car number information, car weight, axle weight, overload, underload and uneven load information of each car, but also the image information of the car.
