Description

Technical Field

[0001] This invention relates to the field of logistics and transportation, and more particularly to a method for detecting the deformation of a compartment layering device. Background Technology

[0002] With the development of China's economy, the importance of the road freight transport industry has been continuously increasing, and it far surpasses other modes of transport in terms of transport volume and turnover. Box trucks are the mainstream tool for road transport, but they are still mainly single-layered for loading and unloading, with manual loading and unloading, resulting in low efficiency, high cost, and limited capacity and utilization of the cargo box.

[0003] Currently, there are solutions for improving vehicle capacity and utilization using compartment layering technology. Existing main layering technologies include fixed layered racks, scissor lift racks, folding racks, and mobile layering devices. Mobile layering devices involve setting tracks on the walls of the vehicle compartment, with the two ends of support rods sliding along the tracks on both sides of the compartment walls and fixed in preset positions. For example, a Chinese patent document, "A Van Compartment," publication number CN103350724A, includes a panel and an inner panel fixed to the panel. It also includes a long, plate-shaped layered plate. The layered plate has protruding connecting portions on both sides and a layering guide rail in the middle. The inner panel and the panel have positioning recesses that match the connecting portions, and the connecting portions on both sides of the layered plate are located at the corresponding positioning recesses.

[0004] Because the walls of the carriage are not rigid, and the movable layering device is perpendicular to the walls, the vehicle is subject to uncertain forces during transportation, such as acceleration, braking, and bumps, which can easily cause deformation of the walls. In addition, the weight of the transported goods is uncertain, with some being full loads and others half loads. The movable layering device is subjected to uneven forces, which can easily cause deformation and lead to it detaching from the walls. Summary of the Invention

[0005] This invention primarily addresses the problem that the walls and support components of existing vans with movable layering devices are prone to deformation, posing a safety hazard during transportation. It provides a method for detecting the deformation of the van's layering device by installing several sensors between the support components and the van walls. The degree of deformation of the van walls and support components is determined by combining and comparing the detected data, and relevant personnel are promptly notified.

[0006] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: A method for detecting the deformation of a car compartment layering device includes the following steps: S1: Several detection capacitors and infrared laser sensors are installed between the support components of the mobile layering device and the carriage wall to obtain detection signal data in real time; S2: Based on the combination and data comparison of the capacitance value of the detection capacitor and the laser beam signal from the infrared laser sensor, determine in sequence whether the support component has detached from the carriage wall, whether the support component has deformed, and whether the carriage wall has deformed. S3: Based on the judgment result, issue an alarm to the relevant staff or return to continue collecting detection signal data.

[0007] Several sensors are installed between the support components of the mobile layering device and the carriage wall. By combining and comparing the detected data, the degree of deformation of the carriage wall and support components is determined, and relevant personnel are promptly notified. This allows for timely detection of deformation of the mobile layering components, ensuring the safe transportation of goods.

[0008] Preferably, an infrared laser sensor is installed on the support assembly; an infrared generator is set at one end of the support assembly; and several infrared receivers are arrayed along the edge of the support assembly at the other end of the support assembly.

[0009] When the support assembly is normally loaded, the corresponding infrared receivers can receive the laser from the infrared generator; when the support assembly is twisted, the other infrared receivers in the vicinity receive the laser from the infrared generator; accordingly, the degree of twisting of the support assembly is determined by the positional relationship between the infrared receivers that receive infrared signals and the infrared generators that receive infrared signals in the historical records; when the support assembly is bent due to excessive load, the infrared receivers cannot receive infrared signals.

[0010] Preferably, a piezoelectric switch is installed at the connection between the support component and the carriage wall, and the piezoelectric switch is connected to the infrared generator of the infrared laser sensor.

[0011] Under normal circumstances, the piezoelectric switch is energized and closed due to the connection between the support assembly and the carriage wall, and the infrared generator can generate an infrared signal. When the distance between the support assembly and the carriage wall is too far, the pressure of the piezoelectric switch is lower than the threshold, so the piezoelectric switch is opened and the infrared generator cannot generate an infrared signal.

[0012] Preferably, at least two capacitors are provided at the connection between the support component and the carriage wall, with the capacitor plates respectively located at the connection ends between the carriage wall and the support component; the capacitors are arranged along the moving direction of the support component.

[0013] Because the capacitance value of a capacitor is related to the distance between the capacitor plates, a comparison of the capacitance values ​​between the capacitors is used to determine whether the support assembly has a tendency to detach. Under otherwise identical conditions, if the capacitance difference between the capacitors exceeds a certain threshold, it indicates that the distance on one side of the connection between the support assembly and the vehicle wall is significantly greater than the distance on the other side. This means the angle between the connection surface of the support assembly and the vehicle wall is too large, posing a risk of detachment.

[0014] As a preferred embodiment, the process for determining whether the support component is detached from the carriage wall is as follows: A1: Determine whether the infrared laser sensor has generated an infrared laser signal. If yes, determine that the support component has not detached from the carriage wall and proceed to the support component deformation judgment; otherwise, proceed to the next judgment. A2: Obtain the capacitance value of the capacitor at the corresponding position and calculate the capacitance difference; determine whether the capacitance difference is greater than the set tolerance threshold. If yes, determine that the support component is detached from the carriage wall; if no, determine that the support component is not detached from the carriage wall and proceed to the support component deformation judgment.

[0015] Preferably, the deformation judgment of the support component includes the bending judgment of the support component and the torsion judgment of the support component.

[0016] Preferably, the bending determination process of the support component is as follows: Determine whether the infrared receiver of the infrared laser sensor receives an infrared signal. If so, determine if the support component is twisted; otherwise, determine if the support component is bent and issue an alarm to the relevant personnel.

[0017] Preferably, the process for determining the torsion of the support component is as follows: Record the locations of infrared receivers that received infrared signals under normal operating conditions of the supporting components in the receiver set from historical data; The system determines whether the infrared receiver receiving the real-time infrared signal is within the receiving set. If so, the support component is considered normal, and the deformation of the carriage wall is assessed. If not, the support component is considered to be twisted, and an alarm is triggered for the relevant personnel.

[0018] As a preferred method, the determination of deformation of the carriage wall includes the following process: Obtain the capacitance values ​​of all capacitors at the connection points between the support components and the carriage walls on both sides; Determine whether all capacitance values ​​are within the preset capacitance threshold range. If so, determine that the carriage wall has not deformed and continue acquiring detection signal data; otherwise, determine that the carriage wall has deformed and issue an alarm to the relevant personnel.

[0019] The beneficial effects of this invention are: 1. Several sensors are installed between the support components of the mobile layering device and the carriage wall. By combining and comparing the detected data, the degree of deformation of the carriage wall and support components is determined, and relevant personnel are promptly notified. This allows for timely detection of deformation of the mobile layering components, ensuring the safe transportation of goods.

[0020] 2. By combining multiple sensors, it can accurately determine the situation in multiple scenarios, resulting in more detailed and convincing judgments. Attached Figure Description

[0021] Figure 1 This is a flowchart of the deformation detection method for the compartment layering device of the present invention. Detailed Implementation

[0022] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example: This embodiment provides a method for detecting the deformation of a carriage layering device, such as... Figure 1 As shown, it includes the following steps: S1: Several detection capacitors and infrared laser sensors are installed between the support components of the mobile layering device and the carriage wall to obtain detection signal data in real time.

[0024] 1) Install an infrared laser sensor on the support assembly.

[0025] An infrared generator is set at one end of the support component, and several infrared receivers are arrayed along the edge of the support component at the other end.

[0026] When the support assembly is normally loaded, the corresponding infrared receivers can receive the laser from the infrared generator.

[0027] When the support component is twisted, other infrared receivers in the vicinity receive the laser light from the infrared generator. Accordingly, the degree of twisting of the support component is determined by the positional relationship between the infrared receivers that received the infrared signal and the infrared generators that received infrared signals in historical records.

[0028] When the support component bends due to excessive weight, the infrared receiver cannot receive infrared signals.

[0029] 2) A piezoelectric switch is installed at the connection between the support component and the carriage wall.

[0030] The piezoelectric switch is connected to the infrared generator of the infrared laser sensor.

[0031] Under normal circumstances, the piezoelectric switch is energized and closed due to the connection between the support assembly and the carriage wall, and the infrared generator can generate an infrared signal.

[0032] When the support component is too far from the carriage wall, the pressure of the piezoelectric switch is lower than the threshold, so the piezoelectric switch is disconnected and the infrared generator cannot generate an infrared signal.

[0033] 3) At least two capacitors are installed at the connection between the support assembly and the carriage wall.

[0034] The capacitor plates are respectively installed at the connection ends of the carriage wall and the support assembly, and the capacitors are arranged along the moving direction of the support assembly.

[0035] Because the capacitance value of a capacitor is related to the distance between the capacitor plates, a comparison of the capacitance values ​​between capacitors can be used to determine whether the support assembly is prone to detachment.

[0036] Under otherwise identical conditions, if the capacitance difference between capacitors is greater than a certain threshold, it is determined that the distance on one side of the connection between the support component and the carriage wall is much greater than the distance on the other side. In other words, the angle between the connection surface of the support component and the carriage wall is too large, and there is a risk of detachment.

[0037] S2: Based on the combination and data comparison of the capacitance value of the detection capacitor and the laser beam signal from the infrared laser sensor, determine in sequence whether the support component has detached from the carriage wall, whether the support component has deformed, and whether the carriage wall has deformed.

[0038] 1) The process for determining whether the support components have detached from the carriage wall is as follows: A1: Determine whether the infrared laser sensor has generated an infrared laser signal. If yes, determine that the support component has not detached from the carriage wall and proceed to the support component deformation judgment; otherwise, proceed to the next judgment.

[0039] A piezoelectric switch is installed at the connection between the support component and the carriage wall, and the piezoelectric switch is connected to the infrared generator of the infrared laser sensor.

[0040] Under normal circumstances, the piezoelectric switch is energized and closed due to the connection between the support assembly and the carriage wall, and the infrared generator can generate an infrared signal.

[0041] When the support component is too far from the carriage wall, the pressure of the piezoelectric switch is lower than the threshold, so the piezoelectric switch is disconnected and the infrared generator cannot generate an infrared signal.

[0042] A2: Obtain the capacitance value of the capacitor at the corresponding position and calculate the capacitance difference; determine whether the capacitance difference is greater than the set tolerance threshold. If yes, determine that the support component is detached from the carriage wall; if no, determine that the support component is not detached from the carriage wall and proceed to the support component deformation judgment.

[0043] Because the capacitance value of a capacitor is related to the distance between the capacitor plates, a comparison of the capacitance values ​​between capacitors can be used to determine whether the support assembly is prone to detachment.

[0044] Under otherwise identical conditions, if the capacitance difference between capacitors is greater than a certain threshold, it is determined that the distance on one side of the connection between the support component and the carriage wall is much greater than the distance on the other side. In other words, the angle between the connection surface of the support component and the carriage wall is too large, and there is a risk of detachment.

[0045] 2) Deformation judgment of support components includes bending judgment of support components and twisting judgment of support components.

[0046] 2.1 The process for determining the bending of the support component is as follows: B1: Determine whether the infrared receiver of the infrared laser sensor receives an infrared signal. If yes, determine if the support component is twisted; otherwise, determine if the support component is bent and issue an alarm to the relevant personnel.

[0047] 2.2 The process for determining the torsion of the supporting components is as follows: B2: Record the locations of infrared receivers that received infrared signals under normal operating conditions of the supporting components in the receiver set from historical data.

[0048] B3: Determine whether the infrared receiver that receives the infrared signal in real time is within the receiving set. If so, determine that the support component is normal and perform a deformation judgment on the carriage wall; if not, determine that the support component is twisted and issue an alarm to the relevant staff.

[0049] When the support assembly is normally loaded, the corresponding infrared receivers can receive the laser from the infrared generator.

[0050] When the support component is twisted, other infrared receivers in the vicinity receive the laser light from the infrared generator. Accordingly, the degree of twisting of the support component is determined by the positional relationship between the infrared receivers that received the infrared signal and the infrared generators that received infrared signals in historical records.

[0051] When the support component bends due to excessive weight, the infrared receiver cannot receive infrared signals.

[0052] 3) The determination of deformation of the carriage wall includes the following process: C1: Obtain the capacitance values ​​of all capacitors at the connection points between the support components and the carriage walls on both sides.

[0053] C2: Determine whether all capacitance values ​​are within the preset capacitance threshold range. If yes, determine that the carriage wall has not deformed and continue to acquire detection signal data; otherwise, determine that the carriage wall has deformed and issue an alarm to the relevant staff.

[0054] If the carriage wall deforms while ensuring that the support components are not deformed, the distance between the carriage wall and the support components will change, and the capacitance of the capacitor set between the carriage wall and the support components will also change. The deformation of the carriage wall can be determined based on the capacitance value of the capacitor.

[0055] S3: Based on the judgment result, issue an alarm to the relevant staff or return to continue collecting detection signal data.

[0056] If the assessment indicates that the support component has detached from the carriage wall, or that the support component is bent, twisted, or that the carriage wall is deformed, an alarm will be issued to the relevant personnel. Otherwise, the acquisition of detection signal data will continue until the transportation of the goods is completed.

[0057] This embodiment of the solution involves installing several sensors between the support components of the mobile layering device and the carriage wall. By combining and comparing the detected data, the degree of deformation of the carriage wall and support components is determined, and relevant personnel are promptly notified. This allows for timely detection of deformation of the mobile layering components, ensuring the safe transportation of goods. The combined use of multiple sensors enables precise assessment of various scenarios, resulting in more detailed and reliable judgments.
