Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment safety, in particular to a vehicle tailgate safety monitoring device. Background Art

[0002] In the contemporary logistics industry, the hydraulic tailgate of a truck compartment is an indispensable cargo loading and unloading component that not only greatly improves loading and unloading efficiency, but also greatly optimizes the logistics and transportation process. With the rapid development of e-commerce and the increasing sophistication of supply chain management, fast, accurate and safe loading and unloading of cargo has become one of the core competitiveness of logistics companies.

[0003] At present, during the cargo loading and unloading process, the hydraulic tail lift is driven by the hydraulic system to achieve the smooth lifting and lowering of the tail lift, so that the forklift or other handling equipment can directly transfer the cargo between the ground and the carriage, which greatly simplifies the heavy labor of loading and unloading that relied on manpower in the past, significantly reduces the labor intensity, and speeds up the logistics turnover.

[0004] However, as hydraulic tail lifts are widely used, their operational safety issues are becoming increasingly prominent. Due to the lack of effective safety protection measures, common hydraulic tail lifts often cause safety accidents due to illegal operations or operational errors in actual applications. For example, operators place goods on the tail lift in an irregular manner or stand in an improper position, which can easily lead to serious consequences such as goods falling and personal injuries; for example, operators fail to avoid the tail lift operation area in time, especially during the tail lift closing process, resulting in being pinched by the tail lift. Therefore, how to ensure the safety of hydraulic tail lift operation and reduce operational risks during cargo loading and unloading is a problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figure 1-8 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] Reference Figure 1-3 The hydraulic tailgate 1 is usually installed at the rear of a cargo transport van for loading and unloading cargo 11. During the loading and unloading process of cargo 11, the hydraulic tailgate 1 often causes serious safety accidents due to operating errors or illegal operations. Figure 1 , 2 As shown, the operator 12 may illegally place the cargo 11 at the wrong position of the tail lift 1 or the operator 12 may directly stand on the tail lift 1, so that during the operation, the tail lift 1 may flip over or perform a door closing operation due to misoperation, causing the cargo 11 to fall or the operator 12 to be injured, resulting in overloading of the tail lift 1 and safety issues for the operator 12. Figure 3 As shown, the operator 12 may also illegally intrude his body into the running track of the tailgate 1 during the closing process, resulting in being clamped by the tailgate 1, causing serious safety accidents. Most of the hydraulic tailgates 1 on the market currently lack effective safety monitoring devices to warn or prevent these incorrect operations or illegal behaviors, and are basically passive text-based operation manuals and instructions for use to restrict operators, which poses great operational risks and safety hazards.

[0039] The utility model embodiment discloses a vehicle compartment tailgate safety monitoring device.

[0040] Reference Figure 4 , Figure 5 , a tailgate safety monitoring device, comprising an image acquisition module, an image processing module 3, a control processor 4, a tailgate control module 5 and a warning module 7 arranged on the tailgate 1 of the carriage;

[0041] An image acquisition module, used for acquiring image data of the operation area of ​​the tailgate 1;

[0042] In some embodiments, the operation area may include the entire area of ​​the surface of the tail lift 1 and may also include a portion of the area around the tail lift 1 , so as to accurately capture the position of the cargo 11 or the person 12 on the surface of the tail lift 1 and the position of the person 12 in the area around the tail lift 1 ;

[0043] The image processing module 3 is connected to the image acquisition module, and is used to receive and process image data and output image processing results;

[0044] A control processor 4, connected to the image processing module 3, for receiving the image processing result and outputting a tailgate control signal in response to the image processing result;

[0045] The tailgate control module 5 is connected to the control processor 4 and is used to control the opening or locking of the tailgate drive mechanism 6 in response to the tailgate control signal; wherein the tailgate drive mechanism 6 is used to drive the tailgate 1 to be raised, lowered or flipped;

[0046] The warning module 7 is connected to the control processor 4. The control processor 4 is used to respond to the image processing result and output a warning control signal. The warning module 7 is used to send corresponding warning information in response to the warning control signal.

[0047] In the embodiment of the present application, a control box 13 is also installed on the tailgate 1 , and the image processing module 3 , the control processor 4 and the tailgate control module 5 are all integrated in the control box 13 .

[0048] In the above-mentioned implementation manner, the image acquisition module is used to monitor the tail lift 1 operation area in real time, and the image data is analyzed by the image processing module 3 to actively identify the violation of the goods 11 or personnel 12 in the tail lift 1 operation area. The control processor 4 can output an accurate tail lift control signal according to the image processing result, and the tail lift control module 5 controls the tail lift drive mechanism 6 in real time according to the tail lift control signal to open or lock the lifting and flipping operations of the tail lift 1; through the physical control mechanism, active prevention of unsafe operations is achieved, such as preventing the tail lift 1 from rising when the goods 11 are not placed correctly, or preventing the tail lift 1 from closing when the personnel 12 are in a dangerous position, thereby ensuring the safety of the operation of the hydraulic tail lift 1, and effectively reducing the operational risks during the loading and unloading of the goods 11, improving the operational efficiency, and providing strong technical support for the transformation of the logistics industry to intelligence and safety.

[0049] Reference Figure 5 As an implementation of the image acquisition module, the image acquisition module may use a camera 2, which is installed on the side of the vehicle compartment opening close to the tailgate 1, and the shooting angle of the camera 2 faces the operation area of ​​the tailgate 1. Specifically, a high-resolution camera 2 may be used to continuously capture image data of the operation area of ​​the tailgate 1, thereby providing an analysis basis for avoiding misoperation and illegal behavior.

[0050] In the above embodiment, the camera 2 is used to capture the image data of the operating area of ​​the tailgate 1 in real time, thereby ensuring the real-time and comprehensive visual monitoring of the tailgate 1 and providing detailed and accurate basic data for subsequent analysis and processing.

[0051] Reference Figure 5 A loading area positioning line 8 is also provided on the surface of the tailgate 1, and the loading area positioning line 8 is used to mark the safe placement area 9 of the cargo 11; by providing intuitive visual guidance for the operators 12, it helps them to quickly and accurately place the cargo 11 in the designated area, avoiding stability problems caused by overloading or improper placement, which not only improves the loading and unloading efficiency, but also reduces the safety hazards caused by incorrect placement of the cargo 11 from the source.

[0052] Among them, loading area positioning lines 8 are engraved or pasted on the surface of the tail lift 1. These positioning lines are designed according to the size, load distribution and operation safety standards of the tail lift 1 to clearly indicate the safe placement range of the goods 11. Their colors and styles (such as grids, contour lines, etc.) are carefully selected to ensure that they are easy to identify under different lighting conditions.

[0053] like Figure 5 The figure is a schematic diagram of the cargo 11 being correctly placed within the positioning line 8 of the loading area. It can be understood that the data acquisition camera 2 captures images of the tailgate 1 operating area in real time, and the image processing module 3 uses an algorithm to analyze these images to identify whether the cargo 11 is located within the positioning line 8 of the loading area, thereby determining whether the cargo 11 is placed in the wrong position.

[0054] Reference Figure 4 As an implementation of the image processing module 3, the image processing module 3 uses advanced image processing algorithms and pattern recognition technology to conduct in-depth analysis of the collected image data; the module can match the reference image template with the real-time image data to identify whether the placement of the goods 11 on the tailgate 1 is correct and whether the behavior of the personnel 12 is compliant, and can quickly identify illegal behaviors or unsafe conditions, providing the possibility for real-time warning and control.

[0055] Specifically, the image processing module 3 first pre-processes the collected image data, including noise reduction, enhancement and edge detection, to optimize the image quality and highlight key elements; then, a deep learning model, such as a convolutional neural network (CNN), is used for feature extraction and object recognition, which can not only accurately distinguish between the goods 11 and the personnel 12, but also make compliance judgments on the identified objects based on preset compliance standards (such as the safe placement area 9 for goods 11, the safe area for personnel 12, etc.), and judge whether the goods 11 are located in the designated safe placement area 9, and whether the personnel 12 are standing in the safe area for personnel 12 outside the operating area of ​​the tailgate 1.

[0056] Reference Figure 6-Figure 8 As shown, Figure 6 It is used to indicate that the cargo 11 is not properly placed in the designated safe placement area 9, and the cargo 11 may fall when the tail lift 1 is raised, lowered or turned over; Figure 7 It is used to indicate that the person 12 is standing in the operating area of ​​the tail lift 1 in violation of the rules, and the person 12 may fall when the tail lift 1 is raised, lowered or turned over; Figure 8 It is used to indicate that the person 12 is not standing in the safety area of ​​the person 12 outside the operating area of ​​the tail lift 1 when the tail lift 1 is closed, and the person 12 may be clamped by the tail lift 1 due to the intrusion of the body when the tail lift 1 is flipped.

[0057] It can be understood that when the image processing module 3 detects the above non-compliance on the tail board 1, it outputs the abnormal image processing result of the tail board 1 area; when it detects that the above non-compliance does not exist, it outputs the normal image processing result of the tail board 1 area.

[0058] Reference Figure 4 As an implementation of the control processor 4, the control processor 4 may include a microcontroller MCU and a microprocessor MPU. By receiving the image processing results from the image processing module 3, the MCU and the MPU can quickly process the information, decide whether intervention measures need to be taken, and output precise tailgate control signals to control the opening or locking of the tailgate drive mechanism 6.

[0059] In some embodiments, for example, when an abnormal image processing result of the tail lift 1 area is received, the control processor 4 locks the tail lift drive mechanism 6 through a tail lift control signal to prevent the tail lift 1 from accidentally moving and causing the goods 11 to fall or the personnel 12 to be injured; when a normal image processing result of the tail lift 1 area is received, the control processor 4 turns on the tail lift drive mechanism 6 through a tail lift control signal, and the tail lift 1 can be driven normally, thereby accurately executing the safety control strategy and demonstrating the ability of intelligent decision-making.

[0060] In addition, in order to further enhance the active safety of the tailgate safety monitoring device of the present application, various types of environmental perception sensors can be integrated into the safety monitoring system, such as lidar, camera 2, ultrasonic sensor and infrared sensor; these sensors continuously collect data on the surrounding environment, including distance, image, moving objects and other information, and the data is pre-processed by a high-performance microcontroller unit (MCU) to filter out noise and perform preliminary analysis, and then passed to a powerful microprocessor unit (MPU) for deep fusion and advanced algorithm processing; the MPU uses machine learning algorithms to analyze the fused data, identify potential dangers in real time, such as approaching obstacles, abnormal behavior monitoring, etc., and trigger early warnings or automatically execute avoidance measures accordingly, thereby ensuring that the system can respond quickly and accurately in complex environments, effectively improving the overall safety performance.

[0061] Reference Figure 4 , Figure 5 As an implementation of the tail lift driving mechanism 6, the tail lift driving mechanism 6 is arranged at the connection between the carriage and the tail lift 1. The tail lift driving mechanism 6 includes a lifting cylinder 61 and a flipping cylinder 62. The lifting cylinder 61 is used to drive the tail lift 1 to lift, and the flipping cylinder 62 is used to drive the tail lift 1 to flip. As a very critical component in the operation of the hydraulic tail lift 1, the lifting cylinder 61 and the flipping cylinder 62 are responsible for the vertical lifting and flipping of the tail lift 1, respectively, to improve the loading and unloading efficiency of logistics.

[0062] Reference Figure 4 As an implementation of the tailgate control module 5, the tailgate control module 5 includes a control circuit 51 and a solenoid valve 52; the control circuit 51 is connected to the solenoid valve 52, and is used to control the on and off of the solenoid valve 52 in response to the tailgate control signal; the solenoid valve 52 is respectively connected to the lifting cylinder 61 and the flip cylinder 62, and is used to control the opening and closing of the lifting cylinder 61 and the flip cylinder 62.

[0063] Among them, the solenoid valve 52 is used as an actuator, which is directly connected to the lifting cylinder 61 and the flip cylinder 62. The change of its on-off state can directly affect the circulation of the oil circuit, and then control the extension and retraction action of the cylinder; for example, when the solenoid valve 52 is energized, the oil circuit is opened, and the cylinder can perform the action; when the solenoid valve 52 is de-energized, the oil circuit is closed, the cylinder action is locked, and the current action cannot be executed or continued.

[0064] In the above embodiment, the control circuit 51 controls the on and off of the solenoid valve 52 according to the control signal, and then opens or locks the lifting cylinder 61 and the flipping cylinder 62 of the tail lift 1, thereby directly intervening in the action of the tail lift 1. Based on the physical control mechanism, active prevention of unsafe operations is achieved; for example, the tail lift 1 is prevented from rising when the cargo 11 is not properly placed, or the tail lift 1 is prevented from closing when the person 12 is in a dangerous position, thereby effectively preventing accidents.

[0065] Reference Figure 4 , Figure 6 As an implementation of the warning module 7, the warning module 7 includes a microphone 71, which can be directly mounted on the tailgate 1. The microphone 71 is used to respond to the warning control signal and send a corresponding voice warning message. By using real-time voice warnings, the operator 12 can be notified of the current safety hazards immediately and intuitively, prompting the operator to take corrective measures immediately to avoid the occurrence of potential accidents.

[0066] Specifically, the microphone 71, as a part of the warning module 7, is directly connected to the control processor 4. When the control processor 4 receives the illegal operation or unsafe state signal recognized by the image processing module 3, it will quickly generate a warning control signal and instruct the microphone 71 to send a preset voice warning message. These voice messages may be standardized safety warning sentences, such as "Please note that the goods 11 are placed incorrectly, please readjust them!" or "Warning, personnel 12 are close to the dangerous area, please evacuate immediately!", etc.

[0067] It is understandable that voice warnings are highly penetrating and immediate, and can more effectively attract the operator's attention, especially in a noisy working environment.

[0068] As another embodiment of the warning module 7, the warning module 7 further includes an indicator light 72, which can be directly mounted on the tailgate 1. The indicator light 72 is used to send corresponding light warning information in response to the warning control signal. The indicator light 72 is used as a visual warning means to supplement the voice warning, and the safety information can be conveyed through visual signals even in a noisy environment or when the operator has limited hearing. Since the light warning is intuitive and visible and can be used both day and night, the universal applicability and effectiveness of the safety alarm are enhanced.

[0069] Specifically, the indicator light 72, as a part of the warning module 7, is directly connected to the control processor 4, and displays safety warning information to the operator 12 through lights of different colors or flashing modes according to the warning control signal sent by the control processor 4. For example, flashing red light may indicate an emergency stop operation, and a continuously lit yellow light may mean that the operation needs to be performed with caution.

[0070] The device can monitor the tail lift 1 operation area in real time, actively detect and prevent misoperation and illegal use, and prevent misoperation and illegal use by actively locking the tail lift drive mechanism 6 and issuing voice and light warnings, thereby truly realizing active safety protection of the tail lift 1 operation and effectively ensuring the safety of goods 11 and personnel 12.

[0071] The implementation principle of a tailgate safety monitoring device of a vehicle compartment in an embodiment of the utility model is as follows:

[0072] 1. When only cargo 11 is placed on the tail lift 1 and the cargo 11 is placed correctly (correctly placed in the safe placement area 9 on the tail lift 1), the image processing module 3 recognizes that the cargo 11 is in a legal position, and the control processor 4 sends a tail lift control signal to open the lifting cylinder 61 and lock the flip cylinder 62. The tail lift control module 5 can control the lifting cylinder 61 to open, allowing the tail lift 1 to be lifted and lowered normally, and control the flip cylinder 62 to lock, so as to prevent the tail lift 1 from tipping over or closing, which may cause a safety accident involving the cargo 11.

[0073] 2. When a person 12 stands on the tailgate 1 in violation of the regulations and / or the cargo 11 is placed in violation of the regulations (not properly placed in the safe placement area 9 on the tailgate 1), the image processing module 3 identifies the violation and controls the processor 4 to send a tailgate control signal to lock the tailgate drive mechanism 6. The tailgate control module 5 can control the tailgate drive mechanism 6 to be locked to prevent lifting or flipping operations. At the same time, the microphone 71 and the indicator light 72 make sound and light alarms to prompt the operator 12 to re-place the cargo 11 or to prompt the operator 12 to leave the dangerous area. When all the violations are corrected, a tailgate control signal to open the tailgate drive mechanism 6 can be sent to release the operation restrictions, and the tailgate drive mechanism 6 can resume normal operation.

[0074] 3. When it is necessary to start the flip cylinder 62 to drive the tailgate 1 to perform the door closing action, the image processing module 3 recognizes that the person 12 is not standing in the person 12 safety area outside the tailgate 1 operating area. At this time, the person 12 may be injured during the flipping of the tailgate 1. The control processor 4 sends a tailgate control signal to lock the flip cylinder 62, and the tailgate control module 5 can control the flip cylinder 62 to lock. At the same time, the microphone 71 and the indicator light 72 give an audible and visual alarm to prompt the operator 12 to leave the dangerous area; when the violation is corrected, the tailgate control signal to start the flip cylinder 62 can be sent to release the operation restriction, and the flip cylinder 62 can perform the door closing operation normally.

[0075] In the embodiment of the present application, by real-time monitoring of the tail lift 1 operating area, illegal operations and potential risks are promptly identified, and the tail lift drive mechanism 6 is actively controlled to prevent misoperation and illegal use. At the same time, a warning message is issued by the warning module 7 to prompt the operator to correct the error, ensuring that the correct judgment and control are made at the first time, thereby ensuring the property safety of the user's cargo 11 and the personal safety of the operator 12.

[0076] As other embodiments of the present application, the same active safety monitoring effect as that of the present application can also be achieved through a laser radar system. Specifically, the image acquisition module can be replaced by a laser radar device, and the image processing module 3 can be replaced by a radar data processing module. A high-precision laser radar device can be installed at the corresponding position of the tail board 1. The radar constructs a three-dimensional point cloud map of the tail board 1 operation area in real time by emitting laser pulses and receiving reflected signals. The point cloud data is then transmitted to the radar data processing module, which analyzes the point cloud data based on deep learning and object recognition technology to determine whether the correct placement of the goods 11 and the specific behavior and position of the personnel 12 meet the safety operation specifications. Once a violation is detected, the radar data processing algorithm transmits the result to the control processor 4, which in turn triggers the corresponding control signal, locks the cylinder execution circuit, and issues a warning through the integrated warning module 7 to guide the operator 12 to correct the behavior, thereby maintaining the safety of the tail board 1 operation. This technical solution retains the real-time monitoring, active safety control and warning functions of the original system, while utilizing the all-weather working ability and powerful spatial resolution of the laser radar to enhance the adaptability and reliability under complex lighting conditions or bad weather.

[0077] The vehicle tailgate safety monitoring device proposed in this application can be widely used in logistics, transportation, warehouse management and other fields in practical applications, and is particularly suitable for scenarios where the hydraulic tailgate 1 needs to be frequently used for loading and unloading goods 11. By improving the safety of the tailgate 1 operation, it can effectively reduce safety accidents caused by misoperation and illegal use, ensure the safety of goods 11 and personnel 12, and has broad market application prospects.

[0078] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any feature disclosed in this specification (including abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
