Description

Technical Field

[0001] This invention relates to the technical field of transport straps, and more specifically, to a control method and control device for an intelligent strapping device for transporting commercial vehicles. Background Technology

[0002] During the transportation of commercial vehicles, securing with straps is a crucial step in ensuring logistical safety. Current technology primarily employs passive mechanical strapping systems, relying mainly on the driver to manually operate the straps, including unwinding, pre-tensioning, and locking. This manual operation method lacks standardized tension control, and is susceptible to variations in individual experience, resulting in tension fluctuations of up to ±40%. Excessive tightness can damage the vehicle's suspension, while insufficient looseness fails to effectively secure the cargo.

[0003] There is currently no good solution to the technical problem that manual adjustment of strap tension in existing technologies relies on personal experience and can easily lead to vehicle damage or fixation failure. Summary of the Invention

[0004] The main objective of this invention is to provide a control method and control device for an intelligent strapping device used in the transportation of commercial vehicles, so as to solve the technical problem that manual adjustment of strap tension in the prior art relies on personal experience, which can easily lead to vehicle damage or fixation failure.

[0005] To achieve the above objectives, according to one aspect of the present invention, a control method for an intelligent strapping device for transporting commercial vehicles is provided. The control method includes the following steps: fixing the intelligent strapping device at a target location on a transport vehicle, wherein the transport vehicle is used to transport a target vehicle; in response to a release command, the straps of the intelligent strapping device extend from the intelligent strapping device under the traction of the target object and hook the tow hook or wheel hub of the target vehicle; upon confirming that the straps have hooked the tow hook or wheel hub of the target vehicle, controlling the intelligent strapping device to enter a pre-tensioning mode, wherein the pre-tensioning mode is used to control the straps to automatically tighten in order to lock the target vehicle.

[0006] Furthermore, controlling the intelligent strapping device to enter the pre-tensioning mode includes: acquiring the output torque of the motor when the motor drives the drum to rotate and tighten the strapping; when it is determined that the output torque reaches a first preset condition, controlling the motor speed to decrease to a slow speed mode; during the process of the motor driving the drum to rotate and tighten the strapping in slow speed mode, detecting the output torque of the motor in real time, and when it is determined that the output torque of the motor reaches a second preset condition, controlling the motor to stop driving the drum.

[0007] Furthermore, when the output torque reaches the first preset condition, the speed of the motor is controlled to be reduced to a slow speed mode, including: when the output torque reaches 90% of the preset target tension, the speed of the motor is controlled to be reduced to 0.05m / s.

[0008] Furthermore, when it is determined that the output torque of the motor reaches the second preset condition, the motor is controlled to stop driving the drum, including: when it is determined that the output torque reaches 97% to 103% of the preset target tension, and after the motor continues to work for a first preset time, the motor is controlled to stop driving the drum.

[0009] Furthermore, the control method also includes: when it is determined that the motor stops driving the drum, controlling the intelligent strapping device to enter the holding mode, in the holding mode, acquiring the tension of the strap in real time, and when it is detected that the tension of the strap drops and exceeds 10% of the preset target tension within a second preset time period, controlling the intelligent strapping device to enter the fine-tuning mode to further tighten the strap.

[0010] Furthermore, the control method also includes: responding to an automatic winding control command, the automatic winding control command being used to control the strap to automatically wind into the intelligent strapping device; acquiring image information of the strap surface, and judging the damage information of the strap based on the image information, wherein the damage information includes damage area information, damage location information, wear information, and crack information; generating early warning information in response to the damage information, the early warning information being used to remind the target object of the damage to the strap.

[0011] Furthermore, in response to damage information, an early warning message is generated, including: comparing the damage information with a preset standard; and if it is determined that the damage information exceeds the preset standard, generating display information and audible and visual alarm information in the early warning message. The display information is used to show the damage to the strap, and the audible and visual alarm information is used to remind the target object that there is damage exceeding the preset standard.

[0012] Furthermore, the damage information is compared with preset standards. If the damage information exceeds the preset standards, display information and audible and visual alarm information are generated in the early warning information. This includes: during the winding process of the strap, edge detection wheels are used to detect flaws on both sides of the strap, and displacement sensors are used to detect the thickness information of the strap. If the thickness information exceeds the preset standards, display information and audible and visual alarm information are generated, and fluorescent markings are sprayed at the damaged location.

[0013] According to another aspect of the present invention, a control device for an intelligent strapping device for transporting commercial vehicles is provided, comprising: a response unit for responding to a release command, wherein the strap of the intelligent strapping device extends out of the intelligent strapping device under the traction of a target object and hooks the tow hook or wheel hub of the target vehicle; and a control unit for controlling the intelligent strapping device to enter a pre-tensioning mode upon confirming that the strap has hooked the tow hook or wheel hub of the target vehicle, wherein the pre-tensioning mode is used to control the strap to automatically tighten to lock the target vehicle.

[0014] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium including a stored executable program, wherein, when the executable program is executed, it controls the device where the storage medium is located to perform the control method described above.

[0015] By applying the technical solution of this invention, the intelligent strapping device is fixed on the carrier. The straps of the intelligent strapping device extend and hook onto the tow hook or wheel hub of the target vehicle, and the intelligent strapping device is controlled to automatically tighten. That is, the tensioning process of the straps is changed from uncontrollable human force to controlled automatic execution by the machine, eliminating uneven force caused by human factors and ensuring precise and stable tension. This not only avoids damage to the vehicle suspension due to excessive tension, but also prevents fixation failure due to insufficient tension. It solves the technical problem in the prior art that manually adjusting the strap tension relies on personal experience, which can easily lead to vehicle damage or fixation failure.

[0023] During the transportation of commercial vehicles, securing the straps is a crucial step in ensuring logistical safety. Currently, most vehicle strapping devices employ passive mechanical structures, relying primarily on the driver to manually perform operations such as strap deployment, pre-tensioning, and locking. This traditional operating method has the following drawbacks:

[0024] 1. Low work efficiency: It takes an average of 8-12 minutes to tie the four wheels of a single vehicle, and manual winding after transportation can easily cause the straps to become tangled and knotted, affecting subsequent use;

[0025] 2. Tension control lacks standardization. Manual operation is greatly affected by differences in individual experience. Tension fluctuation range can reach ±40%. Too tight a tension can damage the vehicle suspension, while too loose a tension can not effectively secure the goods.

[0026] 3. Wear and tear on the straps is difficult to detect in time. When manually rewinding, the driver can only make a rough inspection with the naked eye. Minor internal damage or edge wear is easily overlooked, creating potential safety hazards.

[0027] 4. In low-temperature environments (such as -20°C to -30°C), the strapping material hardens, and the resistance to manual winding increases dramatically, greatly increasing the difficulty of operation and the labor intensity of personnel.

[0028] To address the aforementioned deficiencies, this application provides the following solutions.

[0029] Combination Figure 1 As shown in the specific embodiment of this application, a control method for an intelligent strapping device for transporting commercial vehicles is provided. The control method includes the following steps:

[0030] Step S1: Secure the smart strapping device to the target location on the transport vehicle, which is used to transport the target vehicle.

[0031] For example, the smart strapping device may be equipped with hooks, magnetic bases or buckles, which operators can connect to dedicated anchor points or reinforcing ribs on the side of the carrier.

[0032] Step S2: In response to the release command, the straps of the smart strap device extend from the smart strap device under the traction of the target object and hook the tow hook or wheel hub of the target vehicle.

[0033] For example, the intelligent strapping device includes a drive mechanism for driving the drum to rotate in both directions, with the strap wound onto the drum. The drive mechanism includes a motor and an electromagnetic clutch. The electromagnetic clutch automatically locks the output shaft when the motor is powered off, preventing the strap from retracting. The intelligent strapping device also includes an auxiliary tension sensor and a PID tension closed-loop controller. The auxiliary tension sensor monitors the tension of the strap, and the PID tension closed-loop controller adjusts the motor speed in real time, ensuring the strap tension is precisely and stably maintained within a preset target range, eliminating human error.

[0034] For example, in response to a release command, the electromagnetic clutch disengages, the motor enters a low-damping free-rotation mode or a negative torque assisted release mode, and the strap extends smoothly under the manual traction of the operator or the traction of the vehicle's own weight. When the operator hooks the hook at the end of the strap onto the tow hook or wheel hub of the vehicle, the strap stops being pulled out.

[0035] Step S3: After confirming that the strap has hooked the tow hook or wheel hub of the target vehicle, control the intelligent strap device to enter the pre-tensioning mode, wherein the pre-tensioning mode is used to control the strap to automatically tighten in order to lock the target vehicle.

[0036] For example, the motor reverses to drive the drum so that the straps tighten automatically.

[0037] In the embodiments of this application, the intelligent strapping device is fixed to the carrier. The straps of the intelligent strapping device extend and hook onto the tow hook or wheel hub of the target vehicle, and the intelligent strapping device is controlled to automatically tighten. That is, the tensioning process of the straps is changed from uncontrollable human force to controlled automatic execution by the machine, eliminating uneven force caused by human factors and ensuring precise and stable tension. This not only avoids damage to the vehicle suspension due to excessive tension, but also prevents fixation failure due to insufficient tension. It solves the technical problem in the prior art that manually adjusting the strap tension depends on personal experience, which can easily lead to vehicle damage or fixation failure.

[0038] In another embodiment of this application, step S3, controlling the smart strapping device to enter the pre-tightening mode, includes the following steps:

[0039] Step S311: Obtain the output torque of the motor when the motor drives the drum to rotate and tighten the strapping.

[0040] For example, the motor current is monitored in real time using a Hall sensor and converted into the motor's output torque.

[0041] Step S312: When it is determined that the output torque has reached the first preset condition, the speed of the motor is reduced to slow speed mode.

[0042] For example, a first torque threshold is set in the system. When the torque reaches this value, it indicates that the strap is initially tightened. The system automatically switches to slow mode to avoid tension overshoot caused by the impact inertia generated by high-speed tightening.

[0043] Step S313: During the process of the motor driving the drum to rotate and tighten the strap in slow mode, the output torque of the motor is detected in real time. When it is determined that the output torque of the motor reaches the second preset condition, the motor is controlled to stop driving the drum.

[0044] For example, a second torque threshold is set within the system. In slow mode, when the torque reaches this value, the system controls the motor to stop.

[0045] In the embodiments of this application, when the output torque reaches the first preset condition, it indicates that the strap has been initially tightened. At this time, the speed is automatically reduced to enter a slow mode to avoid tension overshoot or damage to the vehicle suspension caused by the impact inertia generated by high-speed tightening. Secondly, in slow mode, real-time fine adjustment is performed, and the system stops immediately when the torque precisely reaches the second preset condition, keeping the tension error within a very small range. This staged control not only ensures pre-tightening efficiency but also eliminates the uncertainty of human operation, effectively preventing damage to the vehicle due to excessive tightness or fixation failure due to excessive looseness, and significantly improving the safety and standardization of the strapping process.

[0046] Furthermore, when the output torque reaches the first preset condition, the speed of the motor is controlled to be reduced to a slow speed mode, including: when the output torque reaches 90% of the preset target tension, the speed of the motor is controlled to be reduced to 0.05m / s.

[0047] In the embodiments of this application, when the output torque reaches 90% of the preset target tension, the strap is close to its tensile limit. At this point, reducing the winding speed to an extremely low value of 0.05 m / s effectively eliminates tension overshoot caused by motor inertia, preventing damage to the vehicle suspension or strap breakage due to excessive instantaneous tension. Simultaneously, the motor operates at low speed to fine-tune the strap tension, ensuring that the final tension is precisely locked within the target range.

[0048] For example, the target tension is set to 1600N. During the initial pre-tensioning phase, the motor operates at high speed. When the Hall sensor detects that the torque corresponding to the current reaches 1440N (90% of 1600N), the system immediately intervenes, reducing the winding speed from 0.2m / s to a slow, fine-tuning mode of 0.05m / s. This stage allows the PID tension closed-loop controller to fine-tune the speed with a 10ms cycle, avoiding tension overshoot caused by inertial impact. Subsequently, the tension steadily approaches 1600N, achieving high-precision pre-tensioning and preventing damage to the vehicle's suspension due to excessive strap tightness caused by high-speed inertia, ensuring stable and precise tension control.

[0049] Furthermore, when it is determined that the output torque of the motor reaches the second preset condition, the motor is controlled to stop driving the drum, including: when it is determined that the output torque reaches 97% to 103% of the preset target tension, and after the motor continues to work for a first preset time, the motor is controlled to stop driving the drum.

[0050] In the embodiments of this application, the output torque is within the range of 97% to 103% of the preset target tension and is maintained for a first preset duration. The system confirms that the strap tension has truly stabilized, rather than fluctuating briefly. This effectively avoids premature shutdown (insufficient tension) or continuous overtightening (damage to the vehicle) caused by instantaneous impact, ensures the accuracy of the final locking force, completely eliminates human error, and ensures the consistency of operation for different drivers. It is particularly suitable for long-distance commercial vehicle transportation scenarios with extremely high requirements for fixed safety.

[0051] For example, the target tension is set to 1800N. When the motor is pre-tensioned, the Hall sensor detects that the torque corresponding to the current reaches 1800N (0% error), which meets the 97%~103% range. The system keeps the motor running continuously for 2 seconds (first preset duration) to eliminate tension relaxation caused by initial material creep. After 2 seconds, the tension stabilizes at 1810N, the system determines that the target has been met and stops the motor drive. This process ensures that the tension is accurately locked within a high-precision range of ±3%, avoiding premature stopping that leads to excessive looseness or premature stopping that leads to excessive tightness that damages the vehicle, and achieving standardized automatic locking.

[0052] In another embodiment of this application, the control method further includes the following steps:

[0053] Step S321: When it is determined that the motor has stopped driving the drum, the intelligent strapping device is controlled to enter the holding mode. In the holding mode, the tension of the strap is acquired in real time. If the tension of the strap decreases and exceeds 10% of the preset target tension within a second preset time period, the intelligent strapping device is controlled to enter the fine-tuning mode to further tighten the strap.

[0054] In the embodiments of this application, if the tension of the strap drops by more than 10% within a set time, it indicates that the hook has slipped or the material has initially loosened. At this time, the fine-tuning mode is automatically triggered to tighten the strap again without manual intervention. This effectively overcomes the unreliability of manual locking and the safety hazards caused by strap creep, ensuring long-term stable tension and significantly improving transportation safety. It is particularly suitable for long-distance transportation or complex road conditions, and realizes a technological leap from single pre-tensioning to full-process adaptive locking.

[0055] For example, the auxiliary tension sensor continuously monitors the tension of the strap, and if it detects that the tension drops by more than 10% within 30 seconds, it automatically activates the fine-tuning mode to tighten it further.

[0056] For example, by combining with a cloud platform, the tension decay curve can be remotely monitored, providing data support for vehicle route planning. Furthermore, in extreme temperature environments (such as large day-night temperature differences), the thermal expansion and contraction of materials can easily cause tension fluctuations. This control mechanism can automatically compensate for these fluctuations, ensuring continuous locking force, reducing the frequency of manual inspections during transit, and improving logistics operation efficiency and safety.

[0057] In another embodiment of this application, the control method further includes the following steps:

[0058] Step S10: In response to the automatic winding control command, the automatic winding control command is used to control the strap to automatically wind up into the intelligent strapping device.

[0059] For example, when the operator presses the "automatic winding" button, the system controls the electromagnetic clutch to engage, and the motor rotates forward at a constant speed of 0.2 m / s. The strap is pulled from the hook end into the drum groove, and the encoder provides real-time feedback on the winding length to control the stopping time. The inner wall of the drum is equipped with guide combs to ensure that the straps are neatly stacked and prevent tangling. This process is fully automated and requires no manual intervention, achieving rapid storage.

[0060] Step S20: Obtain image information of the strap surface, and determine the damage information of the strap based on the image information. The damage information includes information on the damaged area, the damaged location, wear information, and crack information.

[0061] For example, a linear array CMOS image sensor is installed next to the winding channel to continuously scan the surface of the strap at a line frequency of 10kHz. The light source uses a ring LED to eliminate shadow interference. The image is transmitted to the image processing algorithm module, which detects damage (area ≥ 5mm²), cracks, and edge wear (depth ≥ 0.3mm) through feature extraction. At the same time, an edge mechanical flaw detection wheel, in conjunction with a displacement sensor, records the thickness change curve of the strap. Dual-modal data fusion accurately identifies surface and internal damage and generates damage coordinates and type data.

[0062] Step S30: In response to the damage information, generate a warning message, which is used to remind the target object of the damage to the strap.

[0063] For example, when excessive damage is detected, the system immediately triggers an audible and visual alarm module (buzzer + flashing red LED) and displays the specific defect location on the LCD screen (e.g., "damage 1.2m from the end"). Simultaneously, the device controls a miniature inkjet head to spray a small amount of fluorescent ink at the damaged area for quick location. Data is synchronized to a mobile app via Bluetooth, generating a detection report and pushing it to the logistics company's backend to remind the driver to replace the straps, preventing the use of damaged straps and ensuring transportation safety.

[0064] In the embodiments of this application, the strapping winding and damage detection are carried out simultaneously. Once excessive damage to the strapping is detected, an early warning is immediately generated to prevent the damaged strapping from being reused, thus eliminating potential transportation safety hazards from the source. This integrated winding and detection method not only increases the damage detection rate to over 98%, but also realizes the digitalization of the entire life cycle management of the strapping, ensuring that good strapping is used in every binding operation, greatly reducing the risk of cargo damage caused by strapping failure, and ensuring the safety of vehicle transportation.

[0065] Furthermore, in response to damage information, an early warning message is generated, including: comparing the damage information with a preset standard; and if it is determined that the damage information exceeds the preset standard, generating display information and audible and visual alarm information in the early warning message. The display information is used to show the damage to the strap, and the audible and visual alarm information is used to remind the target object that there is damage exceeding the preset standard.

[0066] In the embodiments of this application, the audible and visual alarm is triggered only when the damage exceeds the standard, ensuring the effectiveness of the warning. The displayed information intuitively presents the location and type of the defect, assisting the driver in making a quick judgment. The audible and visual alarm strengthens on-site reminders and prevents negligence. This tiered early warning mechanism transforms passive inspection into proactive defense, significantly improving the defect detection rate to over 98%, eliminating the reuse of damaged straps, ensuring the safety of commercial vehicle transportation from the source, and reducing operational interference caused by invalid alarms.

[0067] For example, the linear CMOS sensor detected a 6mm [unclear] at a distance of 1.2m from the end.2 The crack is larger than 5mm. 2 Upon reaching the preset threshold, the system immediately triggers an alarm: the LCD screen brightly displays the location coordinates and a "damaged" icon, a buzzer sounds rapidly, and a red light flashes. The driver can quickly locate the defect without needing to inspect the entire route. The device also marks the strap as "discarded" to prevent misuse.

[0068] Furthermore, the damage information is compared with preset standards. If the damage information exceeds the preset standards, display information and audible and visual alarm information are generated in the early warning information. This includes: during the winding process of the strap, edge detection wheels are used to detect flaws on both sides of the strap, and displacement sensors are used to detect the thickness information of the strap. If the thickness information exceeds the preset standards, display information and audible and visual alarm information are generated, and fluorescent markings are sprayed at the damaged location.

[0069] In the embodiments of this application, the edge detection wheel, combined with a displacement sensor, can accurately capture the edge wear depth and thickness reduction that are difficult to detect with the naked eye, compensating for the blind spots of relying solely on image recognition for internal structural damage. When the thickness change exceeds the standard, the system not only provides immediate warnings through audible and visual alarms and screen displays, but more importantly, it automatically sprays fluorescent markings at the damaged area. This marking function transforms the abstract "data alarm" into an intuitive "physical location," enabling drivers to instantly pinpoint the defect location in dimly lit environments or during rapid operations, without the need for repeated checks or reliance on complex readings. This integrated process greatly reduces the risk of human error, ensures that scrapped strapping is accurately isolated, and physically prevents damaged strapping from being reused, comprehensively protecting the safety of vehicle transportation.

[0070] For example, during winding, it was discovered that the edge of the strap was worn, reducing its thickness from 5mm to 3.5mm, below the 4mm threshold. The system determined this to be excessive and immediately triggered an alarm: the LCD screen displayed "Edge Wear" and a buzzer sounded. Simultaneously, a micro-nozzle precisely sprayed fluorescent ink dots 1.5m from the end of the strap. The driver could quickly locate the defect based on the illuminated dots, without needing to stop the machine for detailed inspection. This mechanism transforms hidden internal wear into visible physical markings, combined with audible and visual warnings, ensuring that damaged straps are immediately isolated, preventing misuse, and improving detection efficiency and safety.

[0071] According to another specific embodiment of this application, a control device for an intelligent strapping device for transporting commercial vehicles is provided, such as... Figure 2 As shown, the control device includes a response unit and a control unit.

[0072] Specifically, in response to a release command, the smart strapping device extends under the traction of the target object and hooks the tow hook or wheel hub of the target vehicle. Once the control unit confirms that the strapping has hooked the tow hook or wheel hub of the target vehicle, it controls the smart strapping device to enter a pre-tensioning mode, whereby the pre-tensioning mode controls the strapping to automatically tighten to lock the target vehicle.

[0073] In the embodiments of this application, the aforementioned control device controls the straps of the intelligent strapping device to extend and hook onto the tow hook or wheel hub of the target vehicle, and controls the intelligent strapping device to automatically tighten; that is, the tensioning process of the straps is changed from uncontrollable human force application to controlled automatic machine execution, eliminating uneven force caused by human factors and ensuring precise and stable tension. This not only avoids damage to the vehicle suspension due to excessive tension, but also prevents fixation failure due to insufficient tension, solving the technical problem in the prior art where manually adjusting the strap tension relies on personal experience, which can easily lead to vehicle damage or fixation failure.

[0074] According to another specific embodiment of this application, a computer-readable storage medium is provided, which includes a stored executable program, wherein the executable program controls the device where the storage medium is located to execute the control method described above when it runs.

[0075] In this embodiment, the storage medium may be configured to store a computer program for performing the following steps:

[0076] Step S2: In response to the release command, the straps of the smart strap device extend from the smart strap device under the traction of the target object and hook the tow hook or wheel hub of the target vehicle.

[0077] Step S3: After confirming that the strap has hooked the tow hook or wheel hub of the target vehicle, control the intelligent strap device to enter the pre-tensioning mode, wherein the pre-tensioning mode is used to control the strap to automatically tighten in order to lock the target vehicle.

[0078] In the embodiments of this application, the intelligent strapping device is fixed to the carrier. The straps of the intelligent strapping device extend and hook onto the tow hook or wheel hub of the target vehicle, and the intelligent strapping device is controlled to automatically tighten. That is, the tensioning process of the straps is changed from uncontrollable human force to controlled automatic execution by the machine, eliminating uneven force caused by human factors and ensuring precise and stable tension. This not only avoids damage to the vehicle suspension due to excessive tension, but also prevents fixation failure due to insufficient tension. It solves the technical problem in the prior art that manually adjusting the strap tension depends on personal experience, which can easily lead to vehicle damage or fixation failure.
