Description

[Technical Field]

[0001] The present invention relates to the technical field of railway freight transportation, and in particular to an automatic loading method for a loading building and the loading building. [Background technology]

[0002] The loading building is a type of mechanical equipment for the rapid and quantitative loading of bulk cargo, with the advantages of accurate weighing, balanced loading, high speed, and high efficiency. Because it uses a static weighing method, its theoretical weighing error can be controlled to approximately 1 part in 1000, which is significantly higher than the accuracy of dynamic measurement methods such as railway track balances used in the past.

[0003] A loading building generally consists of a steel tower, a top belt layer, a buffer bin layer, a weighing bin layer, and a ground equipment layer. The steel tower straddles the railway. Cargo transported through the top belt layer is temporarily stored in the buffer bin. When it needs to be loaded onto a train, it is lowered into the weighing bin through a gate plate below the buffer bin. Load cells are installed below each of the four support points of the weighing bin to measure the weight of the cargo lowered into the weighing bin. After the loading weight is reached, the buffer bin gate plate is closed and the weighed cargo is lowered onto the train car, completing the loading operation. At the same time, the weight of the cargo weighed each time for loading is stored in the loading building database to generate a final loading data list.

[0004] In the conventional loading process, an operator in the loading building presses a cycle load button to weigh the cargo to be loaded onto the train car. As the car begins to pass under the chute on the ground equipment level, the operator presses the cycle load button to open the gate plate below the metering bin and place the weighed cargo into the chute. The flow gate plate of the chute then opens, and the cargo is loaded onto the car. During the loading process, the operator constantly adjusts the opening degree of the flow gate plate based on loading experience, while simultaneously monitoring the weight of the cargo remaining in the metering bin to ensure uniformity of the cargo loaded onto the car. To ensure that all cargo is loaded into the car when it completely passes under the chute, the flow gate plate must be opened to its maximum opening degree. Before the next car enters the lower chute, the flow gate plate is closed to the appropriate position. For this reason, operators must maintain a high level of concentration while loading the entire train. When loading each car, they must constantly monitor the uniformity of the load within the car. At the same time, they must monitor the weight of the load in the weighing bin and adjust the opening and closing of the flow gate plate according to their operating experience to ensure the load is evenly distributed across the cars. While constantly adjusting the flow gate plate, they must also press the cyclic load support button to weigh the load to be loaded onto the next train before loading each car. Therefore, loading building operators are required not only to have high levels of operability and operating experience, but also to be highly tolerant of failures, operate for long periods of time, and operate with heavy loads. Summary of the Invention [Problem to be solved by the invention]

[Brief explanation of the drawings]

[0019] [Figure 1] 1 is a control flowchart of an embodiment of an automatic loading method for a loading building proposed by the present invention. [Figure 2] 1 is a control flowchart of an embodiment of an automatic loading method for a loading building proposed by the present invention. [Figure 3]1 is a control flowchart of an embodiment of an automatic loading method for a loading building proposed by the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0020] Preferred Embodiments of the Invention Hereinafter, embodiments of the present invention will be described in detail. Examples of the embodiments are shown in the drawings, and identical or similar elements, or elements having identical or similar functions, are designated by identical or similar reference numerals. The embodiments described below with reference to the drawings are merely examples and are intended to explain the present invention, but are not intended to limit the present invention.

[0021] The loading building comprises a steel tower, a top belt, a buffer bin, a metering bin, and a ground equipment layer, and the steel tower spans the railway. The buffer bin, metering bin, and ground equipment are all installed on the steel tower. The top belt is connected to the buffer bin to transport the cargo to be loaded to the buffer bin for temporary storage. The metering bin measures the weight of the cargo to be loaded onto the train car to ensure that the weight of the cargo loaded onto the train car meets the rated load requirements of the train car.

[0022] When a train car needs to be loaded, the load is discharged into the metering bin through a buffer bin gate plate below the buffer bin. A load cell is installed below the support point of the metering bin to measure the weight of the load discharged into the metering bin. When the weight of the load in the metering bin reaches the loading weight, the buffer bin gate plate is closed. The ground equipment is located below the metering bin, with one end connected to the metering bin and the other end equipped with a flow gate plate, and is located above the train car and equipped with a load discharge chute for discharging the load into the train car.

[0023] When the train car moves below the metering bin, the flow gate plate and the metering bin gate plate are opened, and the weighed load in the metering bin is discharged into the train car, completing the loading operation.

[0024] Referring to Figures 1, 2 and 3, the automatic loading method for the loading building of the present invention includes the following steps:

[0025] setting a gate closing position, a gate opening position, and a cargo discharge position, which are different positions sequentially set on the chute along the traveling direction; That is, the gate closing position, gate opening position, and cargo discharge position are located near the chute and distributed in order in the direction of travel, and each position is a set virtual or real position that is used to determine whether the train cars are entering or leaving the work area.

[0026] setting a threshold load height within a car of the train; Because the loading process of train cars is a dynamic, single-flow loading process, i.e., the train cars pass through a chute as they travel along their longitudinal direction and are discharged in a single pass, it is necessary to detect the load height at the loading position, which is used as a reference for adjusting subsequent loading operations. The height threshold is a range of load heights that meet the loading conditions of the train cars, and the actual load height is compared to determine whether the loading uniformity meets the loading conditions.

[0027] During the loading process of the train car, the position of the front sideboard of the train car is automatically acquired in real time relative to the gate opening position and the load unloading position; When the front sideboard is located in front of the gate opening position in the traveling direction and behind the cargo discharge position in the traveling direction, controlling the flow gate plate to open to prepare for cargo discharge; When the front sideboard is located in front of the load discharge position in the traveling direction, the metering bin gate plate is controlled to open, thereby discharging the load;

[0028] During the cargo unloading process, the position of the rear sideboard of the train car is automatically acquired in real time relative to the gate closing position and the gate opening position; Controlling the flow gate plate to close when the rear side board is located in front of the gate closed position in the traveling direction and behind the gate open position in the traveling direction;

[0029] In the cargo unloading process, the cargo height in the train car is automatically acquired in real time, and the cargo height is compared with a height threshold; controlling the flow gate plate to reduce its opening when the load height is greater than an upper threshold height; and controlling the flow gate plate to increase its opening degree when the cargo height is less than the lower height threshold.

[0030] Referring to Figures 1, 2 and 3, the loading building of the present invention for loading using the above-described loading building automatic loading method comprises a PLC, a first camera, a second camera, a third camera and a fourth camera.

[0031] The PLC has a gate closing position, a gate opening position, a cargo discharge position, and a height threshold set.

[0032] The first camera is positioned corresponding to a position where the train cars enter the loading building, is communicatively connected to the PLC, and is configured to capture and transmit a first video stream to the PLC. The PLC uses a deep machine learning algorithm to determine the position of the front sideboard in each frame of the first video stream, and determines the relative positional relationship between the position of the front sideboard and the set gate opening position and cargo discharge position. If the front sideboard is between the gate opening position and the cargo discharge position, it controls the flow gate plate to open, preparing for cargo discharge.

[0033] The second camera is positioned corresponding to a position where the train cars enter the loading building, is communicatively connected to the PLC, and is configured to capture and transmit a second video stream to the PLC. The PLC uses a deep machine learning algorithm to determine the position of the front sideboard in each frame of the second video stream, determine the relative positional relationship between the position of the front sideboard and the cargo discharge position, and when the front sideboard is located in front of the cargo discharge position in the direction of travel, control the metering bin gate plate to open and discharge the cargo.

[0034] The third camera is located corresponding to a position where the train cars leave the loading building, is communicatively connected to the PLC, and is configured to capture and transmit a third video stream to the PLC. The PLC uses a deep machine learning algorithm to determine the position of the rear sideboard in each frame of the third video stream, and determines the relative positional relationship between the rear sideboard's position and the gate closed position and the gate open position. When the rear sideboard is located between the gate closed position and the gate open position, the PLC controls the flow gate plate to close, thereby completing cargo unloading.

[0035] The fourth camera is installed at a position corresponding to the position where it captures images of the inside of the train car, is communicatively connected to the PLC, and is configured to capture a fourth video stream and transmit it to the PLC. The PLC uses a deep machine learning algorithm to determine the cargo height in each frame of the fourth video stream, compares the cargo height with a height threshold, and controls the opening of the flow gate plate based on the comparison result.

[0036] The automatic loading method for a loading building and the loading building thereof set a gate open position, a cargo discharge position, a gate closed position, and a height threshold, and obtain the positions of the front sideboard and the rear sideboard of a train car, thereby automatically determining the relative positional relationship between the front sideboard and the gate open position and the cargo discharge position, and the relative positional relationship between the rear sideboard and the gate closed position and the gate open position, and automatically controls the flow gate plate and the metering bin gate plate, including opening and closing the flow gate plate, opening and closing the metering bin gate plate, and controlling the opening degree of the metering bin gate plate, to automatically control loading according to the running position of the train car, and control the opening degree of the flow gate plate according to the cargo height in the car, thereby adjusting the loading quality of the cargo in the car, thereby achieving fully automated loading, freeing up workers, improving loading efficiency and loading quality, and improving loading safety.

[0037] According to some embodiments of the present invention, referring to Figures 1, 2 and 3, the loading building further includes a buffer bin gate plate drive device, a metering bin gate plate drive device, and a flow gate plate drive device, which are connected to the buffer bin gate plate, the metering bin gate plate, and the flow gate plate, respectively, electrically connected to the PCL, and controlled by the PCL to open and close and adjust the opening degree.

[0038] According to some embodiments of the present invention, with reference to Figures 1, 2, and 3, the first camera, the second camera, and the third camera installed in the loading building may share one camera or may share two cameras.

[0039] According to some embodiments of the present invention, with reference to FIGS. 1, 2 and 3, the automatic loading method for the loading building further includes the following steps:

[0040] A cargo discharge assist position is set that is located in front of the cargo discharge position in the traveling direction.

[0041] The relative positional relationship between the position of the front side board and the load discharge position and the load discharge assist position is acquired in real time. When the front side board is located in front of the load discharge position in the traveling direction and behind the load discharge assist position in the traveling direction, the metering bin gate plate is controlled to open in order to discharge the load.

[0042] In a loading building embodiment, the PLC is provided with a cargo unloading assist position, and a second video camera captures and transmits a second video stream to the PLC, which determines the relative position of the front sideboard to the cargo unloading position and the cargo unloading assist position based on the second video stream, and uses the automatic loading method described above.

[0043] The automatic loading method for the loading building and the loading building according to this embodiment set the cargo discharge assist position so that the cargo discharge moment is also judged at two boundaries, improving the judgment accuracy and the reliability of loading.

[0044] According to some embodiments of the present invention, referring to Figures 1, 2, and 3, during the cargo discharge process, the weight of the cargo in the metering bin is detected in real time to obtain the cargo discharge speed. The remaining cargo discharge time is calculated based on the remaining cargo and the cargo discharge speed. The remaining running time is obtained based on the speed, length, and running time of the train cars. The remaining cargo discharge time is compared with the remaining running time. If the remaining cargo discharge time is greater than the remaining running time, the opening of the flow gate plate is controlled to increase. If the cargo discharge time is less than the remaining running time, the opening of the flow gate plate is controlled to decrease.

[0045] Specifically, the weight of the load in the metering bin is detected, and the weight difference between adjacent detection times is calculated. The load discharge speed is calculated based on the weight difference and timing difference. The weight of the load in the metering bin, i.e., the weight of the remaining load in the metering bin, is detected in real time. The remaining load discharge time is calculated by dividing the weight of the remaining load in the metering bin by the load discharge speed. The remaining running time of the train cars is calculated from the train's running speed, the length of the train cars, and the running time. In other words, it is the amount of time required for the length of the remaining train cars to leave the loading operation position. Next, the opening degree of the flow gate plate is adjusted based on the result of comparing the remaining load discharge time with the remaining running time.

[0046] The load cells of the loading building of the present invention are communicatively connected to a PLC that is configured to calculate and compare the remaining load unloading time and remaining travel time to accomplish loading using the automatic loading method described above.

[0047] The automatic loading method of the loading building and the loading building according to the present embodiment adjusts the opening degree of the flow gate plate according to the result of comparing the remaining unloading time with the remaining running time, and completes unloading of the cargo at the same time as using up the remaining running time, thereby further improving the uniformity and reliability of the unloading work and the loading quality.

[0048] According to some embodiments of the present invention, referring to Figures 1, 2 and 3, the automatic loading method for a loading building further includes detecting that the rear sideboard is located between the closed gate position and the open gate position and controlling the flow gate plate to open to a maximum opening degree before controlling the flow gate plate to close.

[0049] The loading building of the present invention is arranged according to the automated loading method described above.

[0050] The automatic loading method for the loading building and the loading building of this embodiment ensure that all the loads in the chute correspond to the loads being discharged into the train cars, ensure that all the weighed loads in the metering bins correspond to the loads being discharged into the train cars, and control the flow gate plate to close and open to the maximum opening degree of the flow gate before completing the load discharge, in order to reduce the error between the weighed weight of the loads in the train cars and the actual weight of the loads in the train cars.

[0051] According to some embodiments of the present invention, referring to Figures 1, 2 and 3, in the automatic loading method for a loading building, the identification of the front sideboard, the rear sideboard and the cargo height are all achieved by learning a machine deep learning algorithm.

[0052] The relative positional relationship between the position of the front sideboard and the gate open position and cargo discharge position, the relative positional relationship between the position of the rear sideboard and the gate closed position and the gate open position, and the cargo height inside the vehicle are all identified and determined in real time by machine deep learning learning on the video stream captured by the video camera.

[0053] Specifically, by defining an image or video stream that sets the positional relationship between the front sideboard captured by the video camera and the gate open position and cargo discharge position, and an image or video stream that sets the positional relationship between the rear sideboard captured by the video camera and the gate open position and gate closed position, the PLC obtains the positional relationship that satisfies the control conditions for each, and identifies and judges the image or video stream captured by the video camera in accordance with the obtained control conditions.

[0054] The loading building of the present invention utilizes the automated loading method described above.

[0055] The automatic loading method for a loading building and the loading building according to this embodiment use a deep machine learning algorithm to reduce the difficulty of implementation and improve the accuracy of judgment.

[0056] According to some embodiments of the present invention, with reference to FIGS. 1, 2 and 3, the automatic loading method for the loading building further includes the following steps:

[0057] A vehicle type database is established that includes each vehicle type and its corresponding load rating. The vehicle types include the vehicle types of existing train carriages.

[0058] The type of vehicle of the train to be loaded is identified by the vehicle type identification device, the rated load of the corresponding vehicle type is searched for in the vehicle type database, and the counterweight of the metering bin is automatically set.

[0059] The loading building of the present invention includes a vehicle type identification device communicatively connected to the PLC for identifying the vehicle type, and the loading building uses the above-described automatic loading method.

[0060] The automatic loading method for the loading building and the loading building according to the present embodiment automatically identify the vehicle type through the device, and automatically arrange the weight of the cargo in the weighing bin according to the vehicle type, thereby improving weighing efficiency and weighing accuracy.

[0061] According to some embodiments of the present invention, with reference to FIGS. 1, 2 and 3, the automatic loading method for the loading building further includes the following steps:

[0062] The invalid vehicle number database is formed by inputting the certified invalid vehicle number.

[0063] The vehicle number of the train car to be loaded is identified by a vehicle number identification device and compared with an invalid vehicle number database. If the vehicle number is an invalid vehicle number, the counterweight of the metering bin corresponding to the vehicle number is automatically set to zero, and the metering bin gate plate and the flow gate plate are controlled to close or release the metering bin gate plate and the flow gate plate.

[0064] The loading station according to the present invention includes a vehicle number recognition device communicatively connected to the PCL for recognizing the vehicle number, and the loading station uses the automatic loading method described above.

[0065] The automatic loading method and loading facility of this embodiment form an invalid vehicle number database by inputting invalid vehicle numbers, and the vehicle number identification device identifies the invalid vehicle numbers of each train car during loading work. This solves the problems of difficulty in identifying invalid vehicle numbers due to the delayed notification of invalid vehicle numbers and the more random distribution of invalid vehicle numbers, as well as the difficulty in resuming work after incorrect operation, thereby reducing the difficulty and intensity of the work and improving work efficiency and reliability.

[0066] 1, 2, and 3, the vehicle type identification device is a camera communicatively connected to the PLC for taking multiple photographs of the vehicle type sign positions of the train cars and transmitting the obtained first photographs to the PLC. The PLC performs image identification on the first photograph to extract a vehicle type code, and allocates the weight of the load that needs to be loaded into the metering bin according to the vehicle type code and the vehicle type database.

[0067] The vehicle number identification device is a camera that is communicatively connected to the PLC, takes multiple photographs of the position of the vehicle number sign of the train car, and transmits the resulting second photograph to the PLC. The PLC then performs image recognition on the second photograph to extract the vehicle number and compares it with the input invalid vehicle number. If the vehicle number is an invalid vehicle number, the PLC controls the counterweight of the metering bin to zero.

[0068] According to some embodiments of the present invention, with reference to Figures 1, 2 and 3, when the buffer bin gate plate is opened and the load is discharged into the metering bin, the weight of the load in the metering bin is measured in real time.

[0069] When the weight of the load in the metering bin approaches the set rated load, the opening of the buffer bin gate plate is controlled to be smaller, and the operation of closing the buffer bin gate plate and the operation of opening the buffer bin gate plate to the above-mentioned small opening are repeated, and it is determined whether the rated load has been reached based on the weight of the load when the buffer bin gate plate is closed.

[0070] The loading building according to the present invention uses the above-mentioned automatic loading method.

[0071] The automatic loading method for the loading building and the loading building according to the present embodiment determine whether the weight of the cargo weighed in the metering bin reaches the rated load based on data obtained by static weighing, which is more accurate and improves the accuracy of the weight of the cargo in the train cars.
