Description

Technical Field

[0001] This invention relates to the field of automatic batching and feeding control technology for smelting furnaces, and in particular to an automatic batching and feeding system and method for smelting furnaces. Background Technology

[0002] In the metallurgical, hazardous waste, and solid waste treatment industries, precise control of material conveying and rapid, continuous feeding are crucial for ensuring final product quality, improving production efficiency, and reducing overall operating costs. As a key process connecting material storage and high-temperature smelting, the automation level and rationality of the batching and feeding system design directly determine the stability, accuracy, and continuity of the entire production process.

[0003] Currently, many small and medium-sized hazardous waste and solid waste treatment enterprises face a fundamental constraint in achieving automated batching and feeding: the actual production area of ​​the plant is small, and the operating space around the smelting furnace for equipment layout is extremely limited. Under this reality, traditional and mature automated feeding and batching solutions are often difficult to implement due to high requirements for installation space and linear conveying distance. For example, a one-step long-distance belt conveyor system or a solution with a separate weighing belt conveyor for each discharge port requires a spacious linear layout or a large amount of equipment space, which cannot be achieved in a cramped workshop.

[0004] Therefore, many companies are forced to adopt the inefficient semi-automated mode of "manual assistance forklift transfer" or introduce some automated equipment with simplified structure but fixed function. However, when dealing with production scenarios with multiple smelting furnaces, multiple materials and dynamic demands in a small space, the existing technical solutions have exposed a common systemic defect: their logistics and scheduling strategies lack the necessary flexibility and intelligence, resulting in low utilization of limited automated equipment and failure to achieve efficient collaborative operation.

[0005] Specifically, the existing shortcomings are mainly reflected in the following two interrelated aspects:

[0006] (1) Rigid hardware layout, unable to adapt to compact space and multi-target point requirements: In order to serve multiple smelting furnaces (feeding points) in a limited space, one approach is to use a fixed conveyor line or a single mobile feeding device (such as a walking trolley feeding belt). Although it saves space, its path and the feeding object are fixed or switched sequentially. When multiple furnace openings need to be fed at the same time, the single conveyor resource will cause other furnace openings to wait, resulting in the overall system throughput being limited by the speed of a single device and unable to achieve parallel operation. Another approach is to use multiple fixed high-level silo electronic scales, which not only require a large investment and occupy a lot of space, but also pose operational difficulties and safety risks in installation, calibration and maintenance in a narrow space.

[0007] (2) The control logic is simple and cannot perform dynamic task scheduling and path optimization: The control logic of the existing system is mostly based on fixed sequence or simple triggering conditions (such as low material level alarm), and lacks an intelligent scheduling core that can comprehensively consider the priority of multiple tasks (such as emergency furnace), the status of multiple equipment (idle / busy / position) and global path planning. For example, when multiple furnaces request feeding at the same time, the system cannot perform real-time dynamic task allocation and optimal path planning based on factors such as the current position of the equipment, the material preparation status and the urgency of production. This leads to problems such as idle running and long waiting time of mobile equipment, and path conflicts may occur between different transportation tasks, making it impossible to achieve smooth, unblocked operation of multiple vehicles in a complex track network. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides an automatic batching and feeding system and method for smelting furnaces. It solves the problem that existing automation solutions cannot achieve intelligent scheduling and coordination of multiple devices in confined spaces, resulting in logistics path conflicts, long equipment waiting times, and low overall efficiency.

[0009] According to an embodiment of the present invention, an automatic batching and feeding system for a smelting furnace is provided, the batching and feeding system comprising:

[0010] A batching device is used to store various types of materials and to accurately weigh and batch the stored materials.

[0011] At least two mobile receiving devices, each of which is used to carry and transport materials prepared by the dispensing device;

[0012] A herringbone track network is laid in the work area for all the mobile receiving devices to run along a defined path; the herringbone track network includes a receiving station located below the material discharge end of the batching device, and at least four unloading stations distributed on different smelting furnace sides connected to the receiving station.

[0013] The intelligent scheduling and control device is communicatively connected to the batching device and each of the mobile receiving devices;

[0014] The intelligent scheduling and control device is configured as follows:

[0015] The charging requests from each smelting furnace are acquired in real time, and the status information of each of the mobile receiving devices is monitored in real time. The charging request includes at least the type and weight of the required material and the target smelting furnace number. The status information includes at least the idle / load status and the current position.

[0016] Based on the charging requests of each smelting furnace, the status information of each of the mobile receiving devices, and the real-time occupancy of the herringbone track network, a target mobile receiving device is selected and a unloading task is dynamically assigned to it.

[0017] After assigning tasks, a running path is planned for each of the mobile receiving devices on the herringbone track network, and conflict detection and coordination are performed on the running paths to generate conflict-free path instructions to control multiple mobile receiving devices to work together.

[0018] According to another embodiment of the present invention, an automatic batching and feeding method for a smelting furnace is also provided, the batching and feeding method comprising the following steps:

[0019] The charging requests from each smelting furnace are acquired in real time, and the status information of each mobile receiving device is monitored in real time. The charging request includes at least the type and weight of the required material and the target smelting furnace number. The status information includes at least the idle / load status and the current location.

[0020] Based on the charging requests of each smelting furnace, the status information of each mobile receiving device, and the real-time occupancy of the herringbone track network, a target mobile receiving device is selected and a unloading task is dynamically assigned to it.

[0021] After assigning tasks, a running path is planned for each of the target mobile receiving devices, and conflict detection and coordination are performed on the running paths to generate conflict-free path instructions.

[0022] Control each of the target mobile receiving devices to run along the planned running path to the receiving station, and control the dispensing device to drop the dispensed material into the corresponding target mobile receiving device;

[0023] Control each of the target moving receiving devices to move the material it carries to the corresponding target unloading station and unload it.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] By adopting the deterministic path layout of the herringbone track network and setting up one receiving station and at least four unloading stations in the herringbone track network, a preset, structured running track can be provided for all the mobile receiving devices. The complex two-dimensional planar path planning problem is simplified into a path finding problem between nodes on a fixed topology network. This solves the problems of complex path planning, congestion and conflict in confined spaces of traditional trackless AGVs, and greatly reduces the possibility of path conflict.

[0026] By adopting the intelligent scheduling and control device that integrates real-time status monitoring and dynamic task allocation, it is ensured that unloading tasks can be promptly allocated to idle or nearby mobile receiving devices. This solves the problems of equipment idling or queuing and low overall efficiency caused by uneven task allocation and opaque equipment status, shortens equipment waiting time, and significantly improves system efficiency.

[0027] By employing a path planning method that performs conflict detection and coordination on the herringbone track network with a deterministic path, multiple mobile material receiving devices can operate safely, efficiently, and collaboratively on a shared track network, just like a precisely choreographed train. This solves the problem of track intersection conflicts when multiple devices operate in parallel and achieves conflict-free collaborative operation of multiple devices. Attached Figure Description

[0034] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] like Figure 1 As shown in the figure, an embodiment of the present invention proposes an automatic batching and feeding system for a smelting furnace, the batching and feeding system comprising:

[0037] A batching device is used to store various types of materials and to accurately weigh and batch the stored materials.

[0038] At least two mobile receiving devices 4, each of the mobile receiving devices 4 being used to carry and transport materials prepared by the dispensing device;

[0039] A herringbone track network is laid in the work area for all the mobile receiving devices 4 to run along a defined path; the herringbone track network includes a receiving station 71 located below the material feeding end of the batching device, and at least four unloading stations 72 distributed on different smelting furnace sides connected to the receiving station 71.

[0040] The intelligent scheduling and control device 5 is communicatively connected to the batching device and each of the mobile receiving devices 4;

[0041] The intelligent scheduling and control device 5 is configured as follows:

[0042] The charging requests of each smelting furnace are acquired in real time, and the status information of each of the mobile receiving devices 4 is monitored in real time. The charging request includes at least the required material type, weight and target smelting furnace number, and the status information includes at least the idle / load status and current position.

[0043] Based on the charging requests of each smelting furnace, the status information of each of the mobile receiving devices 4, and the real-time occupancy status of the herringbone track network, a target mobile receiving device 4 is selected and a unloading task is dynamically assigned to it.

[0044] After assigning tasks, a running path is planned for each of the mobile receiving devices 4 on the herringbone track network, and conflict detection and coordination are performed on the running paths to generate conflict-free path instructions to control multiple mobile receiving devices 4 to work together.

[0045] In this embodiment, the herringbone track network provides all the mobile receiving devices 4 with predetermined paths, offering them pre-set, structured running tracks. This simplifies the complex two-dimensional planar path planning problem into a pathfinding problem between nodes on a fixed topology network, greatly reducing the possibility of path conflicts. The intelligent scheduling and control device 5 integrates real-time status monitoring and dynamic task allocation, enabling timely allocation of unloading tasks to idle or nearby mobile receiving devices 4, shortening equipment waiting time and significantly improving system response speed and work efficiency. Furthermore, the intelligent scheduling and control device 5 plans conflict-free running paths for the mobile receiving devices 4 on the herringbone track network, allowing multiple mobile receiving devices 4 to operate safely, efficiently, and collaboratively on the herringbone track network, achieving conflict-free collaborative operation among multiple devices.

[0046] Example 2

[0047] like Figure 2 As shown, based on Embodiment 1, the dispensing device proposed in this embodiment of the invention includes:

[0048] At least two batching bins 1 are used to store different types of materials, and each bin has a discharge port at the bottom;

[0049] Vibrating feeder 2 is disposed below the discharge port of each of the batching bins 1, and is used to receive materials from the corresponding batching bins 1 and feed them evenly in a vibrating manner;

[0050] The weighing belt conveyor 3 has its tail pulley end located below the discharge port of the vibrating feeder 2, and is used to receive materials from the vibrating feeder 2 and meter and convey them to its discharge end.

[0051] More preferably, a flow guide 6 is provided between the vibrating feeder 2 and the weighing belt conveyor 3. The upper end of the flow guide 6 covers the discharge port of the vibrating feeder 2, and the lower end of the flow guide 6 extends above the bearing surface of the weighing belt conveyor 3 to prevent material from spilling.

[0052] More preferably, each of the batching bins 1 is provided with a weighing sensor 11 on its support leg or suspension structure. The weighing sensor 11 is used to monitor the weight change of the material in the corresponding batching bin 1 in real time, so as to perform inventory management of the material in each batching bin 1.

[0053] In this embodiment, at least two batching bins 1 are arranged horizontally in parallel on a high platform in the production workshop, for storing different types of materials to be batched (such as hazardous waste, solid waste, auxiliary materials, etc.), and each batching bin 1 is provided with a discharge port at its bottom. Preferably, a pneumatic gate valve is provided at the discharge port to control the opening and closing of material discharge.

[0054] The vibrating feeder 2 is correspondingly disposed below the discharge port of each of the batching bins 1, with its inlet end softly connected to the discharge port, for receiving materials from the corresponding batching bin 1 and feeding them uniformly in a vibrating manner. Preferably, the vibrating feeder 2 is an electromagnetic vibrating feeder or a motor vibrating feeder, and its vibration frequency and amplitude can be controlled by a frequency converter or a stepless adjustment device to achieve precise adjustment of the feeding speed.

[0055] The tail pulley of the weighing belt conveyor 3 is located below the discharge port of the vibrating feeder 2, and its head pulley extends above the mobile receiving device 4. The weighing belt conveyor 3 is equipped with a weighing module and a speed control unit (such as a variable frequency motor) to meter and convey the received material according to the system set parameters, thereby realizing dynamic weighing function. Preferably, the conveyor belt of the weighing belt conveyor 3 adopts a skirted baffle belt to prevent the material from rolling off during the lifting and conveying process.

[0056] A guide shroud 6 is provided between the vibrating feeder 2 and the weighing belt conveyor 3. The upper end of the guide shroud 6 covers the discharge port of the vibrating feeder 2, and the lower end extends above the bearing surface of the weighing belt conveyor 3, forming a closed material conveying channel to prevent material from spilling during transfer, while reducing dust escape and improving the working environment. Preferably, the inner wall of the guide shroud 6 can be lined with a wear-resistant material, such as a high-molecular-weight polyethylene plate or a manganese steel plate, to extend the service life of the guide shroud 6.

[0057] The specific method for feeding materials in the batching device is as follows:

[0058] (1) Loading and storage: Different types of materials are transported to the corresponding batching bins 1 by a forklift. The intelligent scheduling and control device 5 records the initial inventory of each batching bin 1 through the weighing sensor 11.

[0059] (2) Vibration feeding: The intelligent scheduling and control device 5 starts the corresponding vibrating feeder 2 below the batching bin 1 in sequence according to the current batch formula, so that the material falls onto the weighing belt conveyor 3 after being vibrated evenly by the vibrating feeder 2. During this process, the intelligent scheduling and control device 5 can control the feeding speed by adjusting the vibration parameters of the vibrating feeder 2 to realize the switching between coarse feeding and fine feeding.

[0060] (3) Metering and receiving: The weighing belt conveyor 3 delivers the material to its unloading end according to the running speed set by the intelligent scheduling and control device 5, and the material falls into the receiving hopper 42 that has been moved to the receiving station 71 by the mobile trolley 41 in advance. During this process, the intelligent scheduling and control device 5 receives the weighing signal of the weighing belt conveyor 3 and the signal of the weighing device 43 in real time, and performs double verification to ensure the accuracy of the batching.

[0061] (4) Transfer and unloading: When all the materials in a single batch fall into the receiving hopper 42, the intelligent scheduling and control device 5 controls the mobile trolley 41 to run along the herringbone track network to the designated unloading station 72 (corresponding to the unloading point of the target smelting furnace), and opens the unloading gate at the bottom of the receiving hopper 42 to complete the batching and transfer of the materials. After the unloading is completed, the mobile trolley 41 returns to the unloading station 72 of the first branch group 74 or the second branch group 75 to wait for the next task.

[0062] Preferably, when the mobile trolley 41 receives materials at the receiving station 71, the intelligent scheduling and control device 5 calculates the deviation between the current receiving quantity and the target weight in real time, and dynamically adjusts the running speed of the weighing belt conveyor 3 or the feeding quantity of the vibrating feeder 2 to achieve precise material distribution.

[0063] Example 3

[0064] like Figure 3 As shown, based on Embodiment 2, the mobile receiving device 4 proposed in this embodiment of the invention includes a mobile trolley 41, a receiving hopper 42 supported on the mobile trolley 41, a weighing device 43, and a drive mechanism 44 for driving the mobile trolley 41. The mobile trolley 41 runs on the herringbone track network. The receiving hopper 42 is suspended or supported on the frame of the mobile trolley 41 by the weighing device 43 to monitor the amount of material received by the mobile trolley 41 in real time.

[0065] Furthermore, the herringbone track network includes:

[0066] A main conveying track 73 is arranged along the feeding direction of the weighing belt conveyor 3, and the receiving station 71 is located on the main conveying track 73;

[0067] The first branch group 74 and the second branch group 75 are respectively arranged at both ends of the main conveying track 73. Each branch group includes two branch tracks that are diverged in a herringbone shape. At least two unloading stations 72 are provided at the end of each branch track.

[0068] In this embodiment, the volume of the receiving hopper 42 is configured to accommodate the total volume of a single batch of material. It has an open feed port at the top and a discharge gate (such as a pneumatic butterfly valve or a slide gate valve) at the bottom, which is used to discharge materials into downstream equipment (such as the feed port of a smelting furnace or a transfer silo) at a designated stopping position. The receiving hopper 42 is suspended or supported on the frame of the mobile trolley 41 by the weighing device 43, which is used to monitor the amount of material received in real time and realize closed-loop control.

[0069] Preferably, the herringbone track network is a double-track herringbone track network, which is welded from H-beams or I-beams. The feeding system is equipped with at least four mobile receiving devices 4. The herringbone track network is provided with a first branch group 74 and a second branch group 75. Both the first branch group 74 and the second branch group 75 include a first branch track 761 and a second branch track 762. At least two unloading stations 72 are provided at the end of each branch track. Therefore, the herringbone track network includes one receiving station 71 located below the unloading end of the weighing belt conveyor 3 and at least eight unloading stations 72 located away from the receiving station 71.

[0070] In the initial state, the four unloading stations 72 of the first branch group 74 are used to carry the idle mobile trolley 41 (defined as group A), and the four unloading stations 72 of the second branch group 75 are used to carry the loaded trolley after receiving the material (defined as group B), forming a physical isolation to avoid the empty trolley and the loaded trolley from intersecting in the same area and improve the safety of operation.

[0071] The drive mechanism 44 includes a drive motor, a reducer, and a set of wheels mounted on the mobile trolley 41. The set of wheels rolls in cooperation with the herringbone track network. Preferably, the herringbone track network is provided with a rack, and the mobile trolley 41 is provided with a gear drive mechanism 44 that meshes with it to achieve precise positioning.

[0072] Example 4

[0073] like Figure 4 As shown, based on Embodiment 2, the intelligent scheduling and control device 5 proposed in this embodiment of the invention integrates:

[0074] The anti-collision module 51 is used to monitor the position coordinates and running trajectory of each of the mobile receiving devices 4 in real time. When it is detected that there is a risk of trajectory intersection between two or more of the mobile receiving devices 4, it automatically triggers a deceleration or stop command.

[0075] The error-proof bin verification module 52 is used to compare the mapping relationship between the batching bin 1 number corresponding to each of the mobile receiving devices 4, the ID of each of the mobile receiving devices 4 and the type of material to be unloaded. When it is detected that the type of material does not match the target batching bin 1 number, the vibrating feeder 2 is prohibited from starting.

[0076] In this embodiment, the intelligent scheduling and control device 5 is a PLC control system or an industrial computer, which is communicatively connected to the vibrating feeder 2, the weighing belt conveyor 3, the weighing device 43, and the drive mechanism 44 of the mobile trolley 41. The anti-collision module 51 integrated in the intelligent scheduling and control device 5 monitors the position coordinates and running trajectory of each mobile receiving device 4 in real time through encoders or RFID position tags installed on each mobile receiving device 4 (preferably the mobile trolley 41). When it is detected that there is a risk of trajectory intersection between two or more mobile receiving devices 4 (such as the speed of the rear trolley is greater than that of the front trolley and the distance is less than the safety threshold), it automatically triggers a deceleration or stop command to ensure that each mobile receiving device 4 running on the herringbone track network maintains a safe distance of at least one vehicle position.

[0077] The intelligent scheduling and control device 5 integrates an anti-mismatch silo verification module 52, which includes a position identification sensor (such as a QR code reader or color mark sensor, used to read the ID of the mobile receiving device 4) set at each unloading station 72, and a formula association identifier set at the batching silo 1. This allows the anti-mismatch silo verification module 52 to compare the mapping relationship between the current unloading station 72 number, the ID of the mobile receiving device 4, and the type of material to be unloaded. Thus, when a mismatch is detected between the material type and the target batching silo 1 number (such as a mismatch between the downstream smelting furnace corresponding to the trolley parking position and the current batching silo 1 material), the vibrating feeder 2 is prohibited from starting, and an audible and visual alarm is issued on the operation terminal to prevent mismatched materials from entering the furnace.

[0078] Example 5

[0079] On the other hand, such as Figure 5 As shown in the figure, this embodiment of the invention also provides an automatic batching and feeding method for a smelting furnace, the batching and feeding method comprising the following steps:

[0080] S1. Obtain the charging requests of each smelting furnace in real time, and monitor the status information of each mobile receiving device 4 in real time. The charging request includes at least the required material type, weight and target smelting furnace number. The status information includes at least the idle / load status and current position.

[0081] S2. Based on the feeding requests of each smelting furnace, the status information of each mobile receiving device 4, and the real-time occupancy status of the herringbone track network, select the target mobile receiving device 4 and dynamically assign it unloading tasks.

[0082] S3. After assigning tasks, plan running paths for each target mobile receiving device 4, and perform conflict detection and coordination on the running paths to generate conflict-free path instructions.

[0083] S4. Control each of the target moving receiving devices 4 to run along the planned running path to the receiving station 71, and control the dispensing device to drop the dispensed material into the corresponding target moving receiving device 4.

[0084] S5. Control each of the target moving receiving devices 4 to move the material it carries to the corresponding target unloading station 72 and unload it.

[0085] During the unloading of the target mobile receiving device 4, the system status is continuously monitored. In the event of a sudden system failure, dynamic replanning is immediately triggered. Based on the latest system status, the operating path of the affected target mobile receiving device 4 is adjusted locally or globally, and conflict detection and coordination are performed on the adjusted operating path.

[0086] S6. After the target mobile receiving device 4 completes unloading, its status is updated to idle, and a new round of scheduling calculation is triggered.

[0087] In this embodiment, taking a system comprising four batching bins 1 and four mobile receiving devices 4 (corresponding to multiple smelting furnaces) as an example, the specific working process is as follows:

[0088] In the initial state, the system will allocate the mobile receiving device 4 to different areas according to the preset scheduling strategy. For example, some of the mobile trolleys 41 can be parked near the receiving station 71 close to the unloading end of the batching device, while other mobile trolleys 41 can be parked near the unloading station 72 on different smelting furnace sides. All the mobile trolleys 41 report their "idle / load" status and precise location through the intelligent scheduling control device 5 to prepare for dynamic task allocation.

[0089] When a smelting furnace issues a charging request (including material type, weight, and target furnace number, etc.), the intelligent scheduling and control device 5 begins to coordinate the operation:

[0090] (1) Task Analysis and Cart Selection: The intelligent scheduling and control device 5 analyzes the feeding request issued by the smelting furnace and selects the optimal target car 41 based on the global state (the position and load of each mobile car 41, and the occupancy of the herringbone track network). For example, it selects the mobile car 41 that is closest to the receiving station 71 and is idle to perform the task. After selecting the target car 41, it dynamically assigns unloading tasks to it (the unloading tasks include the type, weight, and batching order of the material to be unloaded by the target car 41). Specifically, this includes: minimizing the overall task completion time or maximizing the utilization rate of the track system as the optimization objective; calculating the comprehensive cost of executing each unloading task based on the estimated travel time between the current position and the target position of the target car 41 and its load status; and using a scheduling algorithm to solve the problem and determine the optimal matching and execution sequence between the target car 41 and each unloading task.

[0091] (2) Path planning and conflict avoidance: The intelligent scheduling and control device 5 uses a path planning algorithm to plan the optimal path from the current position to the receiving station 71 for the selected target mobile car 41 on the herringbone track network, and uses a time window-based algorithm to perform real-time conflict detection. Through the coordination of the algorithm, it ensures that multiple target mobile cars 41 can run without conflict at intersections or shared track sections, and generates conflict-free path instructions.

[0092] (3) Precise batching and metering: After the target moving trolley 41 arrives at the receiving station 71, it starts the vibrating feeder 2 of the corresponding batching bin 1, so that the material is metered by the weighing belt conveyor 3. This process often adopts a "fast-slow-point" feeding strategy, that is, first feed the material quickly to close to the target value, then switch to slow precision feeding, and finally reach the set weight by jogging, so as to ensure that the batching accuracy is better than ±0.5%. During the feeding process, the weighing sensor 11 feeds back the weight signal to the intelligent scheduling and control device 5 in real time to form a closed-loop control.

[0093] (4) Material loading and unloading: After receiving the material, the target mobile trolley 41 carries the prepared material and drives along the planned running path to the unloading station 72 corresponding to the target smelting furnace according to the control command. Upon arrival, it performs the unloading operation (such as automatically opening the unloading gate). While the target mobile trolley 41 is unloading, the system status is continuously monitored. If a sudden situation occurs in the system, dynamic replanning is immediately triggered. Based on the latest system status, the running path of the affected target mobile receiving device 4 is locally or globally adjusted, and the running path is re-detected and coordinated for conflict.

[0094] (5) Cyclic scheduling and efficiency optimization: After unloading, the mobile trolley 41 is changed to "idle" and immediately reported to the intelligent scheduling control device 5, so that the intelligent scheduling control device 5 triggers a new round of scheduling calculation, assigns a new material receiving task to it or makes it return to the standby area. Thus, the intelligent scheduling algorithm can realize the balanced allocation of tasks and the cyclical use of paths of the mobile trolley 41, ensure the continuous operation of the system, maximize the utilization rate of equipment, and reduce labor costs and material turnover time in the field.

[0095] In summary, the system's operation deeply integrates precise metering, real-time closed-loop control, multi-agent path planning, and dynamic production scheduling. Through a collaborative process of "demand triggering → intelligent scheduling → path planning → precise batching → unmanned transportation → automatic unloading → data closure," it achieves efficient, precise, safe, and flexible automation of raw material supply for multiple smelting furnaces within a limited space, significantly improving the system's operating efficiency.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
