Description

Technical Field

[0001] This application relates to the field of fabric technology for fabric handling vehicles, and in particular to a fabric control method, system, and computer-readable storage medium. Background Technology

[0002] In industries such as metallurgy, mining, and building materials, material conveying systems are a crucial part of the production process. Belt-driven concrete placing booms, as key equipment, are responsible for evenly distributing materials to multiple silos. Traditional material distribution methods rely primarily on manual operation or semi-automatic control systems. Operators need to observe the real-time position of the placing boom and the material level in each silo to manually control its trajectory and start / stop. This crude positioning method makes it difficult to ensure the placing boom stops precisely at the preset discharge port. Due to the lack of a precise positioning feedback mechanism, material often spills outside the silo or accumulates unevenly inside, resulting in material waste and impacting subsequent production processes. Furthermore, controlling the silo stacking height relies entirely on the operator's visual observation and experience. This highly subjective control method makes it difficult to achieve stable stacking height control, potentially leading to reduced silo utilization efficiency or material spillage safety hazards. Summary of the Invention

[0003] In view of this, the present application provides a fabric control method, system and computer-readable storage medium, which can effectively solve the problems in the prior art where operators need to observe on-site to judge the real-time position of the fabric carrier and the material level of each hopper, which makes it difficult to ensure that the fabric carrier can accurately stop at the preset unloading port position and may lead to reduced hopper utilization efficiency or material overflow safety hazards.

[0004] In a first aspect, embodiments of this application provide a material control method, which uses a detection device to obtain the current material height of each hopper and the current position of the material distribution vehicle in real time; Based on the height of each material, select one or more target candidate silos with the lowest current material height. When there are multiple target candidate silos, the silo with the shortest running distance is selected as the target silo based on the current position of the material delivery vehicle and the running distance between each target candidate silo. Drive the fabric carrier to the unloading position corresponding to the target hopper; The fabric placing vehicle is controlled to start the fabric placing operation, and the material level height of the target silo is continuously monitored by the detection device; If the material level reaches a preset height threshold, the next target silo is selected again based on the current material level of each silo, until the material level of each silo reaches the preset height threshold.

[0005] In some embodiments, before acquiring the current material height of each hopper and the current position of the material distribution vehicle in real time via the detection device, the material distribution control method further includes: In response to the mode selection input command, it enters automatic operation mode or manual operation mode; In the manual operation mode, the fabric is laid according to the received fabric control instructions. In some embodiments, in the manual operation mode, the fabric spreading according to the received fabric control command includes: The fabric control commands are received via the touchscreen of the human-computer interaction module; The touchscreen is also used to display in real time the material height of each of the hoppers, the current position of the material distribution vehicle, and the current operating mode. In some embodiments, the fabric control method further includes: When the fabric trolley is in operation, the current operating mode is locked, and switching between modes is prohibited through the human-machine interaction module. In some embodiments, the fabric control method further includes: In response to a maintenance status marking command, one or more of the silos are marked as being under maintenance; In the automatic operation mode, silos marked as under maintenance are not included in the screening of the target silos. In some embodiments, after marking one or more of the hoppers as being under maintenance, the fabric control method further includes: Obtain the total storage capacity of the remaining available silos and the current material inflow rate; Calculate the sustainable material receiving time based on the total storage capacity and the material inflow rate; If the continuous material receiving time is less than the preset duration, an alarm signal will be generated.

[0006] In some embodiments, the fabric control method further includes: Real-time acquisition of the operating parameters of the fabric transport vehicle; When any of the operating parameters exceeds the corresponding preset range, the type of operating fault corresponding to the operating parameter that exceeds the preset range is identified, and corresponding alarm information is generated.

[0007] In some embodiments, the detection device includes an infrared beam sensor array and a level gauge.

[0008] Secondly, embodiments of this application provide a fabric control system, including: The acquisition module uses a detection device to obtain the current material height of each hopper and the current position of the material delivery vehicle in real time. The filtering module filters out one or more target candidate silos with the lowest current material height based on the height of each material. The selection module, when there are multiple target candidate hoppers, selects the hopper with the shortest running distance as the target hopper based on the current position of the material distribution vehicle and the running distance between each target candidate hopper; The drive module drives the fabric carrier to the unloading position corresponding to the target hopper; The control module controls the fabric laying vehicle to start the fabric laying operation; The monitoring module continuously monitors the material level in the target silo through the detection device; If the material level reaches a preset height threshold, the judgment module will re-select the next target silo based on the current material height of each silo until the material height of each silo reaches the preset height threshold.

[0009] Thirdly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed on a processor, implements the steps of the above-described fabric control method.

[0010] The embodiments of this application have the following beneficial effects: The material placement control method of this application includes: acquiring the current material height of each hopper and the current position of the material placement vehicle in real time through a detection device; selecting one or more target hoppers with the lowest current material height based on the material height of each hopper; when there are multiple target candidate hoppers, selecting the hopper with the shortest running distance as the target hopper based on the running distance between the current position of the material placement vehicle and each target candidate hopper; driving the material placement vehicle to the unloading position corresponding to the target hopper; controlling the material placement vehicle to start the material placement operation and continuously monitoring the material level height of the target hopper through the detection device; if the material level height reaches a preset height threshold, re-selecting the next target hopper based on the current material height of each hopper, until the material height of each hopper reaches the preset height threshold. The material placement control method of this application dynamically selects the target silo or candidate silo with the lowest current material height by acquiring the material height of each silo and the position of the material placement vehicle in real time. When multiple candidates exist, the method prioritizes the silo with the shortest path as the target silo by combining the running distance between the material placement vehicle and each candidate silo. This effectively shortens the travel distance of the material placement vehicle and reduces idle travel time while meeting the requirements of balanced material placement. By continuously monitoring changes in material level and dynamically updating the target silo after reaching a preset threshold, intelligent sequential material placement among multiple silos is achieved, which significantly improves the automation level, response speed and overall efficiency of the material placement operation.

[0013] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0014] The components of the embodiments of this application described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0017] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0018] Considering that in existing fabric placement operations, the placement of the fabric placing trolley 30 relies on manual visual inspection, making it difficult to accurately align with the unloading port. This easily leads to material spillage or uneven accumulation within the hopper. Furthermore, positioning deviations often require operators to frequently start and stop the motor for adjustment, increasing mechanical impact, accelerating equipment wear, and significantly shortening motor lifespan. Simultaneously, the stacking height relies on visual judgment, lacking precise control, which easily results in low utilization of the hopper 40 or material overflow accidents. In addition, equipment maintenance requires a complete shutdown, and there is a lack of real-time monitoring and intelligent scheduling capabilities for material levels and equipment operating status. Overall, the system suffers from problems such as inaccurate positioning, high equipment wear, inaccurate stacking height control, and low production efficiency. Therefore, this application provides a fabric placement control method. The material distribution control method of this application, which includes a system and a computer-readable storage medium, acquires the material height of each silo 40 and the position of the material distribution vehicle 30 in real time, dynamically filters the target silo 40 or candidate silo 40 with the lowest current material height, and, when multiple candidates exist, combines the running distance between the material distribution vehicle 30 and each candidate silo 40 to prioritize the silo 40 with the shortest path as the target, thereby effectively shortening the travel distance of the material distribution vehicle 30 and reducing idle travel time while meeting the requirements of balanced material distribution; by continuously monitoring material level changes and dynamically updating the target silo 40 after reaching a preset threshold, intelligent sequential material distribution among multiple silos 40 is achieved, significantly improving the automation level, response speed and overall efficiency of the material distribution operation. The following examples illustrate the fabric control method.

[0019] Figure 1 A schematic flowchart of a fabric control method according to an embodiment of this application is shown. It is understood that the fabric control method of this application can be implemented using any type of controller. A programmable logic controller (PLC) can be configured to execute the fabric control method of this application, or a processor can be configured to execute the fabric control method of this application. Exemplarily, a PLC is configured to execute the method. The fabric control method includes steps S101-S106: S101, the current material height of each hopper 40 and the current position of the material distribution vehicle 30 are obtained in real time through the detection device.

[0020] The detection device can be configured according to the actual application. For example, the detection device includes an infrared through-beam sensor array and a level gauge 10. Further, the infrared through-beam sensor array consists of paired infrared through-beam transmitters 20, and the level gauge 10 is a radar-type level gauge. For example... Figure 2 As shown, multiple level gauges 10 are installed inside each silo 40 to continuously monitor the material accumulation height in the corresponding silo 40, collect and upload real-time material level data, thereby forming a globally unified material level status information, providing an accurate basis for the intelligent screening of the target silo 40. At the same time, infrared beam sensor arrays are symmetrically installed on both sides of the top of each silo 40 to form a position recognition network. When the concrete placing vehicle 30 moves along the track, its body blocks infrared beams at different positions. The system can accurately determine the relative position of the vehicle by judging the number of the blocked sensor, realizing real-time monitoring and precise positioning of the concrete placing vehicle 30's running position, ensuring that it can accurately stop at the designated unloading port of the target silo 40, effectively solving the positioning deviation problem caused by traditional manual visual inspection, and improving the automation and precision of the concrete placing operation.

[0021] S102, based on the height of each material, select one or more target silos 40 with the lowest current material height.

[0022] The programmable logic controller (PLC) periodically reads the real-time material level data collected by all level gauges 10 deployed in each silo 40, obtains a complete set of silo 40 height information, analyzes and sorts all material level values, and identifies one or more silos 40 with the lowest current material level. If only one silo 40 has the lowest material level, it is directly identified as the target silo 40.

[0023] If multiple silos 40 have the same material height and are all at the lowest value, these silos 40 are collectively selected as target candidate silos 40 and proceed to the next stage of optimization. This achieves dynamic priority judgment based on the actual material level, ensuring that the material distribution operation always prioritizes replenishing the most urgently needed silos 40, effectively improving the balance of material allocation and the intelligence level of system response.

[0024] S103, when there are multiple target candidate silos 40, the silo 40 with the shortest running distance is selected as the target silo 40 based on the current position of the material distribution vehicle 30 and the running distance between each target candidate silo 40.

[0025] After identifying multiple hoppers 40 with the same or similar material heights and all at the lowest level, a nearest-first optimization strategy is initiated. That is, taking into account spatial location factors, the running distance between the current position of the material delivery vehicle 30 and each target candidate hopper 40 is calculated. Specifically, this distance can be obtained through a preset track position code or by mapping the position signal fed back by the infrared beam sensor array.

[0026] Then, the distance values ​​of each candidate hopper 40 are compared, and the one with the shortest path and least travel time is selected as the actual operation target. This effectively reduces the idle travel distance and ineffective movement time of the placing vehicle 30, reduces equipment energy consumption and mechanical wear, improves overall operation efficiency and response speed, and achieves coordinated optimization of material scheduling in both spatial and demand dimensions.

[0027] S104, drive the material carrier 30 to the unloading position corresponding to the target hopper 40. After identifying the target hopper 40, a running command is sent to the drive motor of the placing trolley 30, initiating the trolley to move along the track towards the target hopper 40. During the movement, a multi-source fusion positioning method combining the level gauge 10 and an infrared beam sensor can be used to acquire the position information of the placing trolley 30 in real time, achieving high-precision collaborative control. When the placing trolley 30 gradually approaches the target hopper 40 based on the positioning signal and reaches the preset unloading start position, the placing trolley 30 is stopped, preparing to enter the material placing operation stage. This dual positioning mechanism significantly improves the accuracy and stability of equipment operation, avoiding positioning deviations caused by errors from a single signal, and ensuring precise, safe, and orderly execution of the material placing operation.

[0028] S105 controls the placing trolley 30 to start the placing operation and continuously monitors the material level height of the target hopper 40 through the detection device.

[0029] Once the material carrier 30 is accurately positioned above the target silo 40 at the unloading location, a start command is sent to the material discharging mechanism of the material carrier 30, such as a belt conveyor or rotary feeder, to initiate the material distribution operation, and the material begins to be evenly distributed into the target silo 40.

[0030] Meanwhile, the level gauge 10 installed inside the target silo 40 collects the material level change data in real time and feeds the signal back to the controller in a continuous or periodic manner; the infrared beam sensor continues to monitor the position of the material carrier 30 to ensure that it remains stable during the material distribution process and prevents uneven unloading or spillage due to deviation.

[0031] By dynamically analyzing the data uploaded by the level gauge 10, the increasing trend of material height within the silo 40 is determined in real time, forming a closed-loop monitoring mechanism. This provides a basis for decision-making regarding whether to terminate the current material placement task and proceed to the next cycle. Synchronous coordination between material placement operations and material level monitoring is achieved, ensuring the controllability, safety, and accuracy of the material feeding process.

[0032] S106, if the material level reaches the preset height threshold, the next target silo 40 is selected again based on the current material height of each silo 40, until the material height of each silo 40 reaches the preset height threshold.

[0033] A preset height threshold can be set according to the actual application. The controller continuously polls the level gauges 10 of all silos 40 at high speed to obtain the global material level status in real time. When it is detected that the material level of the target silo 40 that is currently being fed has risen to the preset height threshold, the task switching mechanism is immediately triggered to stop feeding material to the silo 40 and automatically re-execute the comparison and identification process in step S102. Based on the latest collected material height data of each silo 40, one or more candidate silos 40 with the lowest current material height are dynamically determined.

[0034] During this process, the controller can complete global data acquisition, analysis, and decision-making within milliseconds, quickly locating the next optimal material distribution target. Then, it controls the material distribution trolley 30 to leave the current hopper 40, and following the logic of steps S103 and S104, combined with the precise positioning information provided by the infrared beam sensor, drives the trolley to the unloading position of the new target hopper 40, starting a new round of material distribution. This cycle repeats, achieving intelligent sequential material replenishment between multiple hoppers 40, ensuring that the material in each hopper gradually becomes balanced. Finally, once all hoppers reach the set material level, the material distribution process automatically terminates, fully realizing continuous, intelligent, and high-precision material distribution control under unattended conditions, significantly improving production efficiency and equipment operational stability.

[0035] Furthermore, in one embodiment, based on the above embodiments, before acquiring the current material height of each hopper 40 and the current position of the material distribution vehicle 30 in real time through the detection device, a mode selection operation can be performed first. The system will not default to any mode, adapting to different working conditions while avoiding accidental start-up in an uncontrolled state. For example, in one embodiment, mode selection includes: in response to a mode selection input command, entering an automatic operation mode or a manual operation mode. In automatic operation mode, the dynamic material distribution process of steps S101-S106 above is executed. In manual operation mode, material distribution is performed according to the received material distribution control command. Exemplarily, the material distribution control command can be received through the touch screen of the human-machine interaction module.

[0036] Specifically, users can input control commands and select operating modes via the touchscreen of the human-machine interface module. When automatic operation mode is selected, the controller will autonomously execute the entire process, including material level monitoring, target hopper 40 screening, path optimization, control of the material placing trolley 30, and cyclic material placement, achieving intelligent closed-loop operation without human intervention. When manual operation mode is selected, users can control the movement and start / stop of the material placing trolley 30 using buttons, joysticks, or the touchscreen interface, facilitating equipment debugging, maintenance, or emergency handling. This mode selection mechanism enhances the system's flexibility and operability, balancing automated and efficient operation with the need for manual intervention, and improving the equipment's adaptability and safety in complex production environments.

[0037] Furthermore, users can also set the target material level height threshold for each 40 hopper via the touchscreen, which serves as a judgment benchmark in the automatic control process.

[0038] Understandably, the touchscreen can also be used to display information such as the material height of each hopper 40, the current position of the material distribution vehicle 30, and the current operating mode in real time.

[0039] Specifically, the controller periodically collects analog or digital signals output by the level gauge 10 to obtain real-time material level data for each hopper 40. Combined with the position encoding information fed back by the infrared beam sensor array, it analyzes the precise position coordinates of the material placing vehicle 30 on the track in real time. It also records key parameters such as the current operating mode, the target hopper 40 being worked on, and the status of each actuator. This data is transmitted in real-time to the touchscreen via a communication interface.

[0040] As an example, various parameters can be dynamically presented graphically: for instance, displaying the material level height of each hopper 40 as a bar chart or percentage, showing the current position of the placing vehicle 30 in the sequence of hoppers 40 as a diagram or numerical label, and clearly indicating the current operating mode with icon colors or text labels. In addition, the touchscreen can provide alarm prompts, historical data queries, and operation logs, facilitating users to fully grasp the system's operating status, promptly detect anomalies, and respond accordingly, providing intuitive and reliable information support for on-site operation and remote management.

[0041] When the concrete placing trolley 30 is in operation, the current operating mode is locked, and switching between modes via the human-machine interface module is prohibited. Once a mode is selected and put into operation, it enters a controlled state. When the concrete placing trolley 30 is in operation, including when it is moving along the track or performing concrete placing operations, the controller monitors the equipment's operating signals in real time and automatically locks the current operating mode, prohibiting switching between modes via the human-machine interface module. The lock is only released after the concrete placing trolley 30 has completely stopped, all actuators have been reset to zero, and the system has confirmed that it has entered standby mode. Therefore, if it is necessary to change the operating mode, the "stop and then select" workflow must be strictly followed, i.e., the current operation must be stopped first, and the target mode must be reselected only after the system has confirmed that it has come to a complete stop. This effectively prevents control conflicts, actuator malfunctions, or positioning deviations caused by misoperation, significantly improving the system's safety, stability, and operational standardization.

[0042] Furthermore, in automatic operation mode, during the execution of the dynamic material placement process, such as Figure 3 As shown, the fabric control method also includes: S201 collects the operating parameters of the fabric carrier 30 in the dynamic fabric laying process in real time.

[0043] Specifically, the operating parameters include, but are not limited to: the current and voltage values ​​of the drive motor, the operating status of the frequency converter, the current position signal of the fabric carriage 30, the feedback of the travel limit switch, the communication data of the level gauge 10, the infrared positioning sensor signal, and the status information of the input / output modules.

[0044] S202: When any operating parameter exceeds the corresponding preset range, identify the operating fault type corresponding to the operating parameter that exceeds the preset range and generate the corresponding alarm information.

[0045] It can comprehensively judge multi-variable information through preset thresholds, trend change analysis, input / output signal detection, and logical judgment, and identify fault types such as communication disconnection, abnormal material level exceeding limit, motor overload, trolley overstepping, and signal abnormality, and display alarm information on the touch screen in real time. At the same time, it records the fault occurrence time, type, relevant parameters, and processing results to the local database, providing data support for subsequent equipment maintenance, fault tracing, and process optimization.

[0046] Furthermore, the status of the hopper 40 can be set on the touchscreen. Specifically, a "skip hopper" function interface is provided through the human-machine interface module, allowing users to select one or more hoppers 40 and mark them as under maintenance. For example, when hopper #2 40 needs maintenance, the "skip hopper" function is enabled on the touchscreen and hopper #2 40 is selected. The system responds to this maintenance status marking instruction and marks hopper 40 as under maintenance. When screening the target hopper 40 in automatic operation mode, hoppers 40 marked as under maintenance are automatically excluded. Buddies marked as under maintenance do not participate in the screening of target hoppers 40, thus achieving intelligent skipping of those hoppers 40. As a result, the material carrier 30 only circulates among the remaining normal hoppers 40, completing the maintenance of the hoppers 40 without stopping the machine, achieving uninterrupted maintenance without stopping the machine, and effectively ensuring the continuous operation capability of the production line.

[0047] Furthermore, after marking one or more hoppers 40 as being under maintenance, the controller also has the functions of assessing remaining receiving capacity and providing early warning of production continuity. Specifically, such as... Figure 4 As shown, the fabric control method also includes S301-S303: S301, obtain the total storage capacity of the remaining available silos 40 and the current material inflow rate.

[0048] Specifically, the material inflow rate is the amount of material entering the fabric distribution system per unit time. The sum of the remaining available storage capacity of each 40 silos that are not currently under maintenance, as well as the real-time material inflow rate of the production line, can be obtained by collecting data from upstream belt scales or flow sensors.

[0049] S302, calculate the sustainable material receiving time based on the total storage capacity and material inflow rate.

[0050] Based on the total remaining storage capacity and the current material inflow rate, the duration for which the remaining silo can continuously receive material without overflow is calculated.

[0051] S303 If the continuous material receiving time is less than the preset duration, an alarm signal will be generated.

[0052] The preset duration can be set according to the actual application, such as 30 minutes. If the continuous material receiving time is less than the preset duration, an alarm signal will be generated. The alarm signal can be expressed as a text prompt on the touch screen, an audible and visual warning, or a notification pushed to the operation and maintenance terminal, reminding the operator that the current system's material receiving capacity is insufficient and there is a risk of production interruption or material overflow.

[0053] Building upon this foundation, further auxiliary decision-making suggestions can be generated, such as "Please prioritize restoring the operation of high-capacity silo 40" to optimize maintenance scheduling. This enables intelligent load capacity assessment and risk prediction under multi-silo maintenance conditions, avoiding passive downtime of the entire line due to partial maintenance, and improving the system's operational resilience and management intelligence.

[0054] like Figure 5 As shown, based on the method of the above embodiments, this embodiment provides a fabric control system. Exemplarily, the fabric control system 100 includes: The acquisition module 110 acquires the current material height of each hopper 40 and the current position of the material distribution vehicle 30 in real time through the detection device; The filtering module 120 filters out one or more target candidate silos 40 with the lowest current material height based on the height of each material. Select module 130: When there are multiple target candidate silos 40, select the silo 40 with the shortest running distance as the target silo 40 based on the current position of the material placing vehicle 30 and the running distance between each target candidate silo 40. Drive module 140 drives the material carrier 30 to the unloading position corresponding to the target hopper 40; Control module 150 controls the fabric laying trolley 30 to start the fabric laying operation; The monitoring module 160 continuously monitors the material level height of the target silo 40 through the detection device; If the material level in the judgment module 170 reaches the preset height threshold, the next target material hopper 40 will be selected based on the current material height of each hopper 40 until the material height of each hopper 40 reaches the preset height threshold.
