[0055] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0056] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0057] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0058] Reference Figures 1 to 3 , an intelligent loading control system provided by an embodiment of the present disclosure includes:

[0059] A first position detection module 11 and a control module 12; the first position detection module 11 includes a first detection unit 101 and a second detection unit 102;

[0060] The first detection unit 101 and the second detection unit 102 are both connected to the control module 12 and are both arranged in the unloading area in the loading station; the first detection unit 101 is used to detect the first position of the front end of the target vehicle compartment, and the second detection unit 102 is used to detect the second position of the front end of the target vehicle compartment; the station is the space area where the vehicle is loaded with goods;

[0061] The control module 12 is used to adjust the setting parameters of the material discharging mechanism according to the vehicle information of the target vehicle when the first position of the front end of the target vehicle's compartment is detected; and to control the material discharging mechanism to discharge the material when the second position of the front end of the target vehicle's compartment is detected.

[0062] In this embodiment, the first position detection module 11 includes a first detection unit 101 and a second detection unit 102. The first detection unit 101 and the second detection unit 102 are both connected to the control module 12, and the collected position information of the target vehicle can be sent to the control module 12. Figure 2 and Figure 3 , the first detection unit 101 and the second detection unit 102 are both arranged in the unloading area in the loading station. When the target vehicle has not entered the unloading area, the first distance between the first detection unit 101 and the front end of the carriage of the target vehicle is less than the second distance between the second detection unit 102 and the front end of the carriage of the target vehicle. This means that when the target vehicle drives towards the unloading area, the first detection unit 101 detects the front end of the carriage of the target vehicle before the second detection unit 102.

[0063] The first detection unit 101 may be a position sensor, such as a laser position sensor, which can accurately measure the position of the front end of the carriage by emitting a laser beam and receiving the reflected light. Another example is a capacitive position sensor, which has high accuracy and resolution and can achieve very fine position measurement; at the same time, its response speed is usually fast and can reflect the position change in real time.

[0064] The second detection unit 102 may be a material discharge sensor, which has the same function as the position sensor, both of which are used to detect the position of the front end of the compartment of the target vehicle. Therefore, the material discharge sensor may also be a laser position sensor or a capacitive position sensor.

[0065] In this embodiment, after the target vehicle enters the loading station, the driver will park the vehicle and turn off the engine. The movement of the target vehicle inside the loading station is completed by the operation of the ferry flat car below it. When the first detection unit 101 detects the first position of the front end of the carriage of the target vehicle, the first position can be sent to the control module 12, and the control module 12 will adjust the setting parameters of the discharge mechanism according to the vehicle information of the target vehicle (such as the length, width, height of the carriage and the length, width and height of the interior). The setting parameters include the height of the discharge mechanism and the valve opening of the discharge mechanism. For example, the height of the discharge mechanism is adjusted according to the height of the carriage, the capacity of the carriage is calculated according to the length, width and height of the interior of the carriage, and the valve opening of the discharge mechanism is adjusted according to the capacity of the carriage, so that the coke discharged by the discharge mechanism can accurately fall into the carriage, improve the efficiency of loading, and reduce the cost of vehicle operation time.

[0066] It can be concluded from the above that the present disclosure can accurately detect the position of the target vehicle through the collaborative work of the first detection unit 101 and the second detection unit 102, effectively avoiding the error of manual judgment. The control module 12 can adjust the setting of the discharge mechanism in advance according to the vehicle information, which improves the pertinence and adaptability of loading. When the vehicle is detected to arrive at a specific position, the material is discharged to ensure accurate material delivery, reduce material waste and uneven loading problems. This not only improves loading efficiency, but also reduces transportation costs.

[0067] In one embodiment of the present disclosure, reference Figure 1 and Figure 4 , intelligent loading control system, also includes:

[0068] A second position detection module 13;

[0069] The second position detection module 13 is connected to the control module 12 and is disposed at the entrance of the loading station, and is used to detect the third position of the target vehicle and send the third position of the target vehicle to the control module 12;

[0070] The control module 12 is further configured to calculate a first difference between the third position of the target vehicle and the preset position, and control the servo motor to adjust the target vehicle to the preset position according to the first difference.

[0071] In this embodiment, after the driver drives the target vehicle into the loading station, the control module 12 determines that the parking position is correct and then stops the engine. The specific detection process is as follows:

[0072] The second position detection module 13 includes a fourth detection unit and a fifth detection unit;

[0073] The fourth detection unit is used to detect whether there are any obstacles at the entrance of the loading station. If there are any obstacles at the entrance of the loading station, it will affect the closing of the entrance door; only when the fourth detection unit detects that there are no obstacles, the control module 12 can determine that all target vehicles have entered the designated position of the ferry flat car, and then control the closing of the entrance door. The ferry flat car can also be replaced by a cable traction platform / flat car, an electric mobile platform, a rack mobile flat car, a hydraulic mobile flat car, etc.

[0074] The fifth detection unit is arranged on the ferry flat car, and is used to detect the third position of the target vehicle, and send the data of the third position to the control module 12. The control module 12 determines the preset position according to the vehicle information of the target vehicle stored internally, calculates the first difference between the third position of the target vehicle and the preset position, and determines whether the current position is centered according to the first difference.

[0075] When the absolute value of the first difference is less than or equal to the second preset threshold, it is determined that the current position of the target vehicle is centered; when the absolute value of the first difference is greater than the second preset threshold, it is determined that the current position of the target vehicle is not centered;

[0076] For example, the second preset threshold value can be 10 cm. When the absolute value of the first difference is less than or equal to 10 cm, it indicates that the current position is in the center and there is no need to adjust the position of the target vehicle; when the absolute value of the first difference is greater than 10 cm, it indicates that the current position deviates from the center and the position of the target vehicle needs to be adjusted. Servo motors are provided on both sides of the ferry flat car, and the control module 12 sends instructions to the servo motors according to the first difference between the third position of the target vehicle and the preset position, and adjusts the position of the target vehicle to make it centered.

[0077] From the above, it can be concluded that the second position detection module 13, the control module 12, and the servo motor in this embodiment coordinate with each other so that the target vehicle on the ferry flat car can be parked at a preset position to ensure that the subsequent unloading device can accurately dock with the target vehicle, reducing the repeated adjustment time caused by position deviation, thereby improving the efficiency of the entire loading process.

[0078] In addition to this, during the loading process, if the vehicle position is not accurate, it may cause the goods to be scattered outside the load, resulting in damage to the goods. By adjusting the vehicle position, this risk can be minimized.

[0079] In one embodiment of the present disclosure, the vehicle information of the target vehicle includes cabin size information of the target vehicle;

[0080] Adjust the setting parameters of the unloading mechanism according to the vehicle information of the target vehicle, including:

[0081] The adjustment height of the discharge mechanism and the valve opening of the discharge mechanism are determined according to the compartment size information of the target vehicle.

[0082] In this embodiment, the vehicle information of the target vehicle includes the vehicle compartment size information of the target vehicle, including but not limited to the distance between the front of the vehicle and the compartment, the length, width, height of the compartment, and the length, width, height of the interior of the compartment. The unloading mechanism is initially at an initial height, and after receiving the instruction from the control module 12, it adjusts itself to the height when unloading according to the adjustment height. The adjustment height can be calculated according to the second formula, and the second formula includes:

[0083]

[0084] in, Indicates the adjustment height of the unloading mechanism; Indicates the initial height of the unloading mechanism; Indicates the height of the interior of the car; V rIndicates the volume of materials that need to be put into the carriage; Indicates the length of the interior of the carriage; Indicates the width of the interior of the carriage; a indicates the correction factor, which is determined based on material properties and actual experience and is used to take into account the irregularity of the material stacking shape; Indicates the buffer height reserved to prevent material overflow and ensure the discharge effect.

[0085] In this embodiment, the correction coefficient a, when the cargo is coke, can be 0.8.

[0086] For example, assuming that the interior of the carriage is 5 meters long, 3 meters wide, and 2 meters high, the volume of material to be placed is 20 cubic meters, the initial height of the discharge mechanism is 3 meters, the correction coefficient a is 0.8, and the buffer height is reserved. is 0.2 m, then the adjustment height of the unloading mechanism is =2.46 meters, that is, the unloading mechanism needs to move vertically downward by 0.54 meters.

[0087] In this embodiment, the discharge valve of the discharge mechanism is fan-shaped, and the valve can also be implemented by a gate valve, a common fan-shaped valve, a discharger, etc. The valve opening of the discharge mechanism can be determined according to the compartment size information of the target vehicle and the third formula, and the third formula includes:

[0088]

[0089] in, Indicates the valve opening of the discharge mechanism; It indicates the volume of materials put into the carriage per unit time; T indicates the set discharge time; S is the flow coefficient of the material, which is related to the properties of the material (such as viscosity, particle size, etc.); Indicates the height of the interior of the carriage; Indicates the height of the material currently in the carriage; P represents the pressure coefficient.

[0090] If the material is coke, then in the third formula, S can be 0.8. P is the pressure coefficient, which is related to the pressure setting of the discharge mechanism and can be 2. For example, assuming that the interior height of the carriage is 2 meters, the current material height in the carriage is 0, and it is expected that 20 cubic meters of material will be put in within 30 minutes, the material flow coefficient is 0.8, and the pressure coefficient is 2, then the valve opening is 83.3%. When the volume of material put into the carriage remains unchanged, the shorter the expected time, the larger the valve opening, and the maximum valve opening is 100%.

[0091] The pressure coefficient mainly reflects the degree of influence of pressure on material flow during the discharge process. A higher pressure coefficient value means that under the same other conditions (such as compartment height difference, expected discharge volume, discharge time and material flow coefficient, etc.), a larger valve opening is required to achieve the same discharge effect. This is because a higher pressure coefficient value indicates that there is greater resistance or pressure restriction during the discharge process, and a more open valve is required to ensure that the material can flow at the desired speed and volume. On the contrary, a lower pressure coefficient value indicates that the influence of pressure during the discharge process is relatively small, and a smaller valve opening may achieve the desired discharge effect.

[0092] In actual application, the P value can be obtained through experimental measurement. For example, different pressure sources can be set, and multiple discharge experiments can be carried out under the same other conditions. The pressure, flow rate and other data in each experiment can be recorded, and the P value can be determined by regression analysis and other methods.

[0093] It can be concluded from the above that the present embodiment can accurately adjust the height and valve opening of the discharge mechanism according to the size of the compartment of the target vehicle, which effectively avoids material overflow or insufficient filling, improves discharge efficiency and accuracy, reduces material waste, and ensures the safety and stability of the discharge process.

[0094] In one embodiment of the present disclosure, the vehicle information of the target vehicle includes the driving speed and vehicle compartment size information of the target vehicle;

[0095] Adjust the setting parameters of the unloading mechanism according to the vehicle information of the target vehicle, including:

[0096] The adjustment height of the unloading mechanism, the valve opening of the unloading mechanism and the unloading speed of the unloading mechanism are determined according to the compartment size information and the driving speed of the target vehicle.

[0097] In this embodiment, the adjustment height of the discharge mechanism can be calculated according to the second formula above. Because the ferry flat car does not run at a constant speed in actual situations, the valve opening of the discharge mechanism and the discharge speed of the discharge mechanism need to be adjusted according to the driving speed of the target vehicle. For example, the valve opening of the discharge mechanism is calculated according to the fourth formula, and the fourth formula includes:

[0098]

[0099] in, Indicates the valve opening of the discharge mechanism; It indicates the volume of materials put into the carriage per unit time; T indicates the set discharge time; S is the flow coefficient of the material, which is related to the properties of the material (such as viscosity, particle size, etc.); Indicates the height of the interior of the carriage; Indicates the height of the material in the current compartment; P indicates the pressure coefficient; , is the coefficient, n is a constant, and The functional relationship between them can be obtained by fitting a series of discharge experimental data through mathematical methods.

[0100] When the target vehicle is traveling at a faster speed, The larger the value, the larger the valve opening, so that more materials can be put in a shorter time; when the travel speed is slow, The value is small, and the valve opening is appropriately reduced to avoid material accumulation or spillage.

[0101] The unloading speed of the unloading mechanism is calculated according to the fifth formula, and the fifth formula includes:

[0102]

[0103] in, Indicates the unloading speed of the unloading mechanism; Indicates a basic discharge rate, which is predetermined by experiment or experience; represents the adjustment factor related to the target vehicle's speed; is the adjustment factor related to the car body size.

[0104] This can be obtained through multiple unloading experiments at preset speeds, for example:

[0105] Set up experimental scenarios with different driving speeds: select a series of representative target vehicle driving speeds. Keep the car size and other conditions unchanged: in each experiment, ensure that other factors such as the car size, material characteristics, and the initial settings of the unloading mechanism remain stable. Conduct unloading experiments: at each set driving speed, start the unloading mechanism and record the actual amount of material put into the car within a certain period of time. Calculate the ideal unloading amount: based on the car size and the set unloading time, calculate the ideal unloading amount at this speed. Compare the actual and ideal unloading amounts: calculate the ratio of the actual unloading amount to the ideal unloading amount. This ratio is Repeat the experiment and average the data: Perform multiple experiments at each speed and take the average value to get a more accurate value. value.

[0106] This can be obtained by experimenting with a variety of different vehicle models, for example:

[0107] Prepare vehicles with compartments of different sizes: Select vehicles with compartments of different lengths, widths, and heights as experimental subjects. Keep the driving speed and other conditions unchanged: In each experiment, fix the driving speed of the target vehicle as well as other factors such as material characteristics and the initial settings of the unloading mechanism. Conduct unloading experiments: Under each compartment size, perform unloading operations and record the actual amount of material placed in the compartment within a certain period of time. Calculate the ideal unloading amount: According to the specific size of the compartment and the set unloading time, calculate the ideal unloading amount under the compartment size. Compare the actual and ideal unloading amounts: Calculate the ratio of the actual unloading amount to the ideal unloading amount. This ratio is Repeat the experiment and average the data: perform multiple experiments for each cabin size and take the average value to get a more accurate value. value.

[0108] It can be concluded from the above that this embodiment adjusts the unloading mechanism parameters in combination with the compartment size and driving speed of the target vehicle, can accurately adapt to different vehicles, and improve the unloading efficiency and quality.

[0109] In one embodiment of the present disclosure, the intelligent loading control system further includes:

[0110] Height detection module 14;

[0111] The height detection module 14 is connected to the control module 12 and is disposed above the loading station to detect the height of the material inside the compartment of the target vehicle;

[0112] The control module 12 is also used to control the discharge mechanism to adjust the valve opening according to the material height when the material height inside the compartment of the target vehicle is less than a first threshold value.

[0113] In this embodiment, the intelligent loading control system further includes a height detection module 14, which is connected to the control module 12 and is disposed on the upper part of the loading station to detect the height of the material inside the compartment of the target vehicle; when the height of the material inside the compartment of the target vehicle is less than the first threshold, the control module 12 adjusts the valve opening according to the first formula. The first formula includes:

[0114]

[0115] in, Indicates the valve opening of the discharge mechanism; Indicates the remaining volume of materials that need to be put into the carriage; T r It indicates the estimated time to complete the remaining discharge; S is the flow coefficient of the material, which is related to the properties of the material (such as viscosity, particle size, etc.); Indicates the preset material height threshold, the first threshold; Indicates the height of the material in the current compartment; P indicates the pressure coefficient; Represents a function about the current material height.

[0116]

[0117] Where b and c are coefficients determined by experiment or experience.

[0118] Assume that the internal height of the carriage is 2 meters, the first threshold is 1.4 meters, the current material height is 0.9 meters, the remaining material volume is 3 cubic meters, the estimated time to complete the remaining discharge is 5 minutes, the flow coefficient is 0.8, the pressure coefficient is 2, a is 0.4, b is 0.1, and the valve opening is 80%.

[0119] From the above, it can be concluded that because the first threshold is the threshold with the largest valve opening and the highest loading efficiency, when the material height inside the compartment of the target vehicle is less than the first threshold, the closer the material height is to the first threshold, the larger the valve opening. The first threshold can be a threshold set by the staff based on historical experience, and the first threshold is different for different compartment sizes.

[0120] In one embodiment of the present disclosure, reference Figure 1 and Figure 5 , the first detection unit 101 and the second detection unit 102 are also used to detect the position information of the rear end of the target vehicle compartment;

[0121] The control module 12 is also used to control the valve of the discharge mechanism to close after a first delay time when the position information of the rear end of the target vehicle compartment is detected, and to adjust the height of the discharge mechanism.

[0122] In this embodiment, the first detection unit 101 and the second detection unit 102 are also used to detect the position information of the rear end of the target vehicle. When the first detection unit 101 detects the rear end of the target vehicle, the control module 12 starts the timing function (the timing time is the first duration), and the discharge valve of the discharge mechanism is closed after the timing ends. When the second detection unit 102 detects the rear end of the target vehicle, the control module 12 sends a command to the lifting device of the discharge mechanism to control the discharge mechanism to return to the initial height.

[0123] From the above, it can be concluded that this embodiment realizes intelligent control of the discharge mechanism by adding a position detection function for the rear end of the carriage. It can not only accurately sense the position of the rear end of the carriage, but also accurately control the delayed closing of the valve according to this information, effectively avoiding material overflow. At the same time, the height of the discharge mechanism is adjusted to adapt to different vehicle models, thereby improving loading efficiency and accuracy, reducing manual intervention, and reducing operating difficulty and cost.

[0124] In one embodiment of the present disclosure, the intelligent loading control system, referring to Figure 1 , also includes:

[0125] Weight detection module 15;

[0126] The weight detection module 15 is connected to the control module 12 and is used to detect the weight of the cargo loaded on the target vehicle and send the weight of the cargo loaded on the target vehicle to the control module 12;

[0127] The control module 12 is also used to calculate a second difference between the weight of the cargo loaded on the target vehicle and the preset weight; if the second difference is greater than a preset threshold value, the first preset threshold value is controlled to replenish the cargo.

[0128] In this embodiment, the weight detection module 15 is disposed below the target vehicle, i.e., on the ferry flat car, for detecting the weight of the cargo loaded on the target vehicle in real time, and sending the weight of the cargo loaded on the target vehicle to the control module 12. The control module 12 is also used to calculate the second difference between the weight of the cargo loaded on the target vehicle and the preset weight.

[0129] If the second difference is greater than the preset threshold value, it means that the weight of the cargo loaded on the vehicle does not meet the preset standard. The control module 12 controls the feeding device to start and further accurately feed a small amount of cargo until it reaches the preset weight.

[0130] If the second difference is less than or equal to the first preset threshold, it indicates that the weight of the cargo loaded on the vehicle reaches the preset standard, and there is no need to start the feeding device for feeding. The feeding device can be a rotary quantitative valve, or a gate valve, a discharge valve, a quantitative bucket, etc.

[0131] At the same time, because the weight detection module 15 can detect the weight of the cargo loaded on the target vehicle in real time, the control module 12 can control the driving speed of the ferry flat car according to the weight of the cargo loaded on the target vehicle, and can also control the unloading speed of the unloading mechanism according to the weight of the cargo loaded on the target vehicle.

[0132] For example, a cargo weight-driving speed mapping table is established, and the control module 12 receives cargo weight data in real time, calculates the corresponding driving speed by querying the mapping table or using a preset algorithm (such as linear interpolation), and sends instructions to the drive system of the ferry flat car to adjust its speed.

[0133] The proportional coefficient is set, and the control module 12 calculates the discharge speed according to the real-time cargo weight multiplied by the proportional coefficient, and adjusts the control parameters of the discharge mechanism. For example, for every ton of cargo weight increase, the discharge speed increases by 10%. Or the cargo weight is divided into multiple intervals, and each interval corresponds to a fixed discharge speed. For example, when the cargo weight is 0-5 tons, the discharge speed is 5 cubic meters / minute; when the cargo weight is 5-10 tons, the discharge speed is 8 cubic meters / minute.

[0134] It can be concluded from the above that this embodiment realizes real-time monitoring and precise control of the weight of the cargo loaded on the target vehicle by adding the weight detection module 15. When it is detected that there is a significant deviation between the loading weight and the preset value, the system can automatically trigger the replenishment device to accurately replenish the cargo, ensure that the loading volume meets the standard, reduce human errors, and improve loading efficiency and accuracy.

[0135] In one embodiment of the present disclosure, reference Figure 6 - Figure 8 The control module 12 is also used to control the first gate at the workstation exit to open when it is detected that the weight of the cargo loaded on the target vehicle is equal to the preset weight.

[0136] In this embodiment, when the control module 12 detects that the weight of the cargo loaded on the target vehicle is equal to the preset weight, the shuttle bus continues to travel to the exit of the loading station, triggering the limit switch (pit edge sensor) at the exit, and the shuttle bus slows down and stops. At this time, the control module 12 controls the first gate at the exit of the station to open. After the first gate is opened, the driver starts the engine and drives out according to the instructions. When the vehicle drives out and the sensor (exit sensor) detects that the vehicle has completely driven out, the ferry flat car starts and returns to the original station. When the ferry flat car returns, the exit limit switch is restored, and the first gate is closed. It can be concluded from the above that this embodiment realizes the intelligent management of the loading process by automatically controlling the opening and closing of the gate. When the cargo weight meets the standard, the gate opens automatically, which improves the operating efficiency and safety, while reducing manual intervention and ensuring the smoothness and accuracy of the loading process.

[0137] In one embodiment of the present disclosure, the intelligent loading control system, referring to Fig. 9 - Fig.10 , also includes:

[0138] A first recognition module 16 and a third position detection module 17;

[0139] The first identification module 16 and the third position detection module 17 are both connected to the control module 12;

[0140] The control module 12 is also used to determine the workstation corresponding to the target vehicle according to the vehicle information identified by the first identification module 16;

[0141] Whether to allow the target vehicle to enter the workstation is determined based on the matching result between the vehicle information detected by the third position detection module 17 at the workstation entrance and the identity information of the target vehicle.

[0142] In this embodiment, the first identification module 16 is set in the loading area. All vehicles to be loaded enter the loading area through the access card detection port, and multiple access card detection ports can be set according to the traffic flow. The first identification module 16 identifies the license plate, the front of the vehicle, the carriage, and measures the length, width, and height of the carriage and the length, width, and height inside the carriage at the access card detection port. After the first identification module 16 finishes the identification, it packs and sends the vehicle information to the control module 12, and the control module 12 analyzes and then conducts allocation and scheduling. A screen is set at the access card detection port to display prompt information, indicating to the driver which work station the vehicle should enter, such as "Vehicle XXXX enters work station XX". Then, the detection gate raises the rod to release, and the vehicle enters the loading area.

[0143] After the vehicle enters the loading area, the driver drives the vehicle to wait outside the corresponding loading work station according to the screen indication. The third position detection module 17 outside the loading work station detects whether the vehicle information matches the identity information of the target vehicle. If it matches, it indicates that the vehicle can enter this work station; if it does not match, it indicates that the vehicle cannot enter this work station. The third position detection module 17 can include devices such as ultrasonic sensors and high-definition cameras, which can accurately identify the license plate number of the vehicle and compare this information with the information of the target vehicle. After being accurate and error-free, the vehicle is allowed to enter this work station.

[0144] For example, suppose there is a large coke loading area with multiple intelligent loading work stations set up.

[0145] At the access card detection port, multiple channels are provided to adapt to different traffic flows. A truck with a license plate of "Ji A12345" drives into one of the channels. The first identification module 16 identifies information such as the license plate, the characteristics of the front of the vehicle, the length of the carriage is 6 meters, the width is 2.5 meters, the height is 2 meters, the length inside the carriage is 5.8 meters, the width is 2.3 meters, and the height is 1.8 meters through a high-definition camera and relevant sensors. This information is packed and sent to the control module 12. After analysis, the control module 12 determines that the vehicle should go to work station 5, and displays "Vehicle Ji A12345 enters work station 5" on the screen at the access card detection port. The detection gate raises the rod to release, and the truck enters the loading area.

[0146] The truck driver drives the vehicle to wait outside work station 5 according to the indication. The high-definition camera and ultrasonic sensor in the third position detection module 17 outside the work station detect the vehicle information again. The camera accurately identifies that the license plate number is still "Ji A12345", which matches the identity information of the target vehicle. Immediately, it indicates that the vehicle can enter the work station for loading operations.

[0147] For another vehicle with a license plate of "Ji B67890", which is assigned to work station 3, but the driver mistakenly drives to outside work station 5. The third position detection module 17 detects that the license plate number does not match the target vehicle at work station 5, indicates that the vehicle cannot enter this work station, and prompts the driver to go to the correct work station 3 through voice.

[0148] It can be concluded from the above that this embodiment achieves accurate identification of vehicle information and automatic allocation of workstations by introducing the first identification module 16 and the third position detection module 17, thereby improving the efficiency and accuracy of vehicle scheduling in the loading area, ensuring that the target vehicle can enter the designated workstation accurately, and improving the overall intelligent level of loading.

[0149] In one embodiment of the present disclosure, the interior of the discharge chute of the discharge mechanism is designed with a specific curved surface, so that the material is evenly spread during the falling process, ensuring that the material surface on the top of the compartment of the target vehicle is a flat surface or an upper curved surface. The traveling vehicle in the loading station has a three-layer structure, with the bottom layer for traveling, the middle layer for weighing, and the upper layer for left and right lateral adjustment (used to adjust the position of the target vehicle).

[0150] In one embodiment of the present disclosure, the operation process of the entire intelligent loading control system is as follows:

[0151] ① Vehicle detection and identification → ② Information dispatch guidance → ③ Vehicle information verification and access → ④ Vehicle enters the ferry platform → ⑤ Door closing → ⑥ Vehicle alignment and adjustment → ⑦ Carriage front end positioning → ⑧ Ferry platform automatically starts running → ⑨ Equipment automatically starts loading → ⑩ Spraying → ⑪ Ferry platform moves to the exit and stops → ⑫ Exit door opens → ⑬ Screen displays exit → ⑭ Vehicle drives out → ⑮ Exit door closes after detecting that the vehicle has completely driven out → ⑯ Ferry vehicle quickly returns → ⑰ Process completed

[0152] This system can uniformly allocate incoming vehicles, conduct overall dispatch management, and jointly complete loading operations; realize fully automatic loading of coke without manual intervention; can realize full loading, level loading, and no spilling of materials; the loading process has a weighing function to accurately control the loading weight. This system is an automated intelligent control system that can complete multiple functions such as alarm, historical data storage, storage, display, query of historical curves, and printing reports. During information dispatch, all data is dispatched as a whole through the computer of the control module 12. The control module 12 needs to collect warehouse information, workstation information, vehicle information, etc., and uniformly dispatch to ensure efficient loading. The hardware equipment used by the control module 12 must be able to communicate signals with other PLCs in the factory area and can communicate effectively with each other. The control module 12 also includes information management computers, ticket printers and other related equipment. The information management computer communicates with the background server of the mine coal sales system and can share data.

[0153] The power system of this system is equipped with an energy storage device, and the control module 12 is equipped with an external power supply. When there are sudden power outages, oil pump pressure loss and other emergencies, the oil released by the energy storage device completes the closing of the fan valve, lifting and closing of the flap. When the ferry flat car stops due to a fault in the middle of the journey, the program controls all valve closing devices to be retracted to prevent accidents. The lifting chute of the discharge mechanism can be realized by a cylinder, an electric telescopic rod, a winch rope, etc. The discharge mechanism is composed of a warehouse discharge valve, a material distribution section chute, a lifting section chute, an outlet large and small flap chute, etc., and can also be realized by a discharge valve, a swing chute, a material distribution chute, a scraper chute, etc.

[0154] The curves and guide devices inside the discharge mechanism can achieve the function of uniform discharge surface and reduce the speed of coke flow, thereby achieving the purpose of reducing coke breakage. The discharge mechanism is also equipped with a large flap guide device, which can control the direction of the induced wind and set a dust suction port on the path of the induced wind. The dust can be sucked away with a small air volume, which can greatly reduce the dust concentration in the surrounding environment and save energy by about 60%. The discharge mechanism is made of wear-resistant materials, with high durability, long service life and low daily maintenance.

[0155] The system is also equipped with an explosion-proof video monitoring system (4 explosion-proof cameras in each group, respectively observing the driver's condition, loading condition, running condition, etc.), which can be remotely controlled by connecting to the central control room. In addition, a front and rear anti-collision system is also set up, and the discharge mechanism can automatically retract the discharge port in the event of a power outage or collision due to misoperation.

[0156] Fig.11 A flow chart of an intelligent loading control method provided in an embodiment of the present disclosure. The intelligent loading control method includes:

[0157] S101: When a first position of the front end of the carriage of the target vehicle is detected, setting parameters of the unloading mechanism are adjusted according to vehicle information of the target vehicle;

[0158] S102: When the second position of the front end of the target vehicle's compartment is detected, the discharge mechanism is controlled to discharge the material; the first position is the position where the first detection unit detects the front end of the target vehicle's compartment, and the second position is the position where the second detection unit detects the front end of the target vehicle's compartment; the first detection unit and the second detection unit are both arranged in the discharge area within the loading station, and the station is the space area where the vehicle loads goods.

[0159] In this embodiment, after the target vehicle enters the loading station, the driver will park the vehicle and turn off the engine. The movement of the target vehicle inside the loading station is completed by the operation of the ferry flat car below it. When the first detection unit detects the first position of the front end of the carriage of the target vehicle, the first position can be sent to the control module, and the control module will adjust the setting parameters of the discharge mechanism according to the vehicle information of the target vehicle (such as the length, width, height of the carriage and the length, width, and height of the interior). The setting parameters include the height of the discharge mechanism and the valve opening of the discharge mechanism. For example, the height of the discharge mechanism is adjusted according to the height of the carriage, the capacity of the carriage is calculated according to the length, width, and height of the interior of the carriage, and the valve opening of the discharge mechanism is adjusted according to the capacity of the carriage, so that the coke discharged by the discharge mechanism can accurately fall into the carriage, improve the efficiency of loading, and reduce the cost of vehicle operation time.
