Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive sampling equipment technology, and more specifically to a device and method for identifying the location of vehicle bracing. Background Technology
[0002] Vehicle stiffeners specifically refer to the metal reinforcing beams welded or riveted to the side wall panels inside the cargo compartment of commercial vehicles such as freight trucks and trailers to enhance the structural strength of the compartment.
[0003] The truck sampler is mainly used to collect coal samples from inside a truck bed. The sampler primarily consists of a sprocket lifting mechanism, a trolley, a sampling mechanism, etc. It employs an ultrasonic positioning system for truck bed positioning, preventing damage to the truck bed walls and floor. The traveling mechanism is controlled by frequency converters, ensuring smooth start and stop, and can form a three-dimensional X, Y, Z structure with the sampling mechanism, guaranteeing that the sampling mechanism can collect coal samples from any location inside the truck bed.
[0004] Before sampling begins, personnel need to input vehicle information into the system, including license plate number, cargo box length, cargo box width, chassis height, etc. When sampling begins, the ultrasonic sensor moves with the vehicle. When the ultrasonic sensor detects the rear of the vehicle, it marks the current coordinates as the cargo box origin and then moves to the corresponding position based on the input cargo box data. To prevent the sampling head from touching the sides or internal bracing of the cargo box during sampling, the cargo box data must be accurately entered, the traveling mechanism must be accurately positioned, and a safe distance must be maintained.
[0005] Combination Figure 1 and 2 However, the tie rods inside the vehicle are usually obscured by materials, making it impossible for operators to observe their actual position. During sampling, the sampling head avoids contact with the tie rods primarily through pre-entered vehicle model data and the accuracy of the positioning system. If the positioning system malfunctions or the vehicle model measurement is inaccurate, the sampling head may contact the tie rods, leading to damage to the equipment and the vehicle.
[0006] Furthermore, the tie rods inside the carriages vary in width. Since the entered carriage data does not include the width information for each tie rod, the control system can only avoid blind spots based on the widest tie rod during the sampling process. Summary of the Invention
[0007] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a device and method for identifying the position of vehicle tie rods, thereby solving the technical problem of how to avoid the sampling head from touching the tie rod in the prior art.
[0008] To achieve the above-mentioned technical objectives, the present invention provides a device for identifying the position of a vehicle tie rod, comprising: The identification elements are located on the outside of the carriage, and the positions of the identification elements correspond one-to-one with the positions of the tie rods inside the carriage. An industrial camera is installed on the same plane as the sampling head of the sampling mechanism and moves synchronously with the sampling mechanism. It is used to scan the markers in the area where the sampling head descends and to obtain the marker information. The control system is signal-connected to the industrial camera and sampling mechanism, and is used to receive information transmitted by the industrial camera and control the movement of the sampling mechanism according to the information transmitted by the industrial camera. If the control system receives information from the industrial camera that the identification device has been acquired, it controls the sampling mechanism to avoid the area where the tie rod is located and perform sampling.
[0009] In any implementation, the identification element stores the width information of the corresponding tie rod, the control system calculates the distance the sampling mechanism needs to move, and controls the sampling mechanism to avoid the area where the tie rod is located when sampling.
[0010] In any implementation, the identifier is a QR code.
[0011] In any implementation, the QR code is affixed to the vehicle body by means of a sticker.
[0012] In any embodiment, the QR code includes a rear QR code, a front QR code, and several QR codes corresponding to the tie rods. The rear QR code is located on the outer side of the rear of the carriage, the front QR code is located on the outer side of the front of the carriage, and several QR codes corresponding to the tie rods are respectively located on the outer side of the carriage corresponding to each tie rod.
[0013] Furthermore, this invention also proposes a method for identifying the position of vehicle tie rods, comprising: Preparation before sampling: Set up markers on the outside of the carriage to ensure that the setting position of the markers corresponding to the tie rods is consistent with the position of the tie rods inside the carriage. Set up corresponding markers at the rear and front of the carriage respectively. Sampling area scanning: The control system controls the sampling mechanism to move to the sampling point. The industrial camera simultaneously scans the area where the sampling head descends to check for any markers corresponding to the tie rods. If a marker corresponding to a tie rod is found, the corresponding tie rod in that area is avoided.
[0014] In any implementation, if the identification piece corresponding to the tie rod is identified, the system further includes an industrial camera acquiring the tie rod width L1 stored in the identification piece and transmitting it to the control system. The control system calculates the horizontal distance L = L1 / 2 + L3 + L2 that the sampling mechanism needs to move based on the preset horizontal distance L3 of the tie rod outer edge protection and the horizontal distance L2 between the sampling head and the center of the tie rod. After the control system controls the sampling mechanism to move to a safe area in combination with the horizontal distance L, the sampling head descends to complete the sampling.
[0015] In any implementation, before sampling begins, vehicle model information needs to be entered into the control system. This vehicle model information includes license plate number, cargo box length, cargo box width, chassis height, and brace width. The control system controls the movement distance of the sampling mechanism based on the entered information.
[0016] Compared with existing technologies, the beneficial effects of this invention include: the identification device for the location of vehicle tie rods proposed in this invention includes: an identifier disposed on the outside of the vehicle body, the position of the identifier corresponding one-to-one with the position of the tie rod inside the vehicle body; an industrial camera installed on the same plane as the sampling head of the sampling mechanism and moving synchronously with the sampling mechanism, used to scan the identifiers within the area where the sampling head descends and acquire identifier information; and a control system connected to the industrial camera and the sampling mechanism, used to receive information transmitted by the industrial camera, control the movement of the sampling mechanism according to the information transmitted by the industrial camera, and if the control system receives that the industrial camera has acquired identifier information, it controls the sampling mechanism to avoid sampling the area where the tie rod is located. During the sampling process, the location of the tie rod in the vehicle body is identified in real time by identifying the identifier, avoiding the sampling head from touching the tie rod.

[0024] The "range" disclosed in this application is defined by a lower limit and an upper limit. A given range is defined by selecting a lower limit and an upper limit, which define the boundaries of a particular range. Ranges defined in this way can include or exclude endpoints and can be arbitrarily combined; that is, any lower limit can be combined with any upper limit to form a range. For example, if ranges of 60~120 and 80~110 are listed for a specific parameter, it is also expected that ranges of 60~110 and 80~120 are also included. Furthermore, if minimum range values of 1 and 2 are listed, and if maximum range values of 3, 4, and 5 are listed, then the following ranges are all expected: 1~3, 1~4, 1~5, 2~3, 2~4, and 2~5. In this application, unless otherwise stated, the numerical range "a~b" represents a shortened representation of any combination of real numbers between a and b, where a and b are real numbers. For example, the numerical range "0~5" indicates that all real numbers between "0~5" have been listed in this article; "0~5" is simply a shortened representation of these numerical combinations. Furthermore, when a parameter is stated as an integer ≥2, it is equivalent to disclosing that the parameter is, for example, an integer such as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc.

[0026] Unless otherwise specified, the term "or" is inclusive in this application. For example, the phrase "A or B" means "A, B, or both A and B". More specifically, the condition "A or B" is satisfied by any of the following conditions: A is true (or exists) and B is false (or does not exist); A is false (or does not exist) and B is true (or exists); or both A and B are true (or exist).
[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0028] In this invention, the terms "some embodiments," "this embodiment," and examples are used to describe a subset of all possible embodiments. However, it is understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.
[0029] If the application documents contain similar descriptions such as "first / second", the following explanation shall be added: In the following description, the terms "first / second / third" are used only to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.
[0030] In this embodiment, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, object A and / or object B can represent three situations: object A exists alone, object A and object B exist simultaneously, and object B exists alone.
[0031] The following describes embodiments of this application. The embodiments described below are exemplary and are only used to explain this application, and should not be construed as limiting this application. Where specific techniques or conditions are not specified in the embodiments, they are performed according to the techniques or conditions described in the literature in this field or according to the product instructions. Reagents or instruments used, unless otherwise specified, are all conventional products that can be obtained commercially.
[0032] Example 1 Combination Figure 3-5 This embodiment provides a device for identifying the location of a vehicle's bracing, including: Identifier 1 is located on the outside of carriage 0, and the position of the identifier 1 corresponds one-to-one with the position of the tie rod 3 inside carriage 0. The industrial camera 2 is installed on the same plane as the sampling head of the sampling mechanism 4 and moves synchronously with the sampling mechanism 4. It is used to scan the marker 1 in the area where the sampling head descends and to obtain the information of the marker 1. The control system is connected to the industrial camera 2 and the sampling mechanism 4 by signal. It is used to receive the information transmitted by the industrial camera 2 and control the movement of the sampling mechanism 4 according to the information transmitted by the industrial camera 2. If the control system receives that the industrial camera 2 has obtained the information of the marker 1, it controls the sampling mechanism 4 to avoid the area where the tie rod 3 is located and sample.
[0033] Based on the above embodiments, the identification component 1 in this embodiment stores the width information of the corresponding tie rod 3, the control system calculates the distance that the sampling mechanism 4 needs to move, and controls the sampling mechanism 4 to avoid the area where the tie rod 3 is located for sampling.
[0034] Based on the above embodiments, the identification element 1 in this embodiment is a QR code.
[0035] Based on the above embodiments, the QR code described in this embodiment is fixed to the vehicle body by pasting.
[0036] Based on the above embodiments, the QR codes in this embodiment include a QR code at the rear of the carriage 0, a QR code at the front of the carriage 0, and several QR codes corresponding to the tie rods 3. The QR code at the rear of the carriage 0 is located on the outer side of the rear of the carriage 0, and the QR code at the front of the carriage 0 is located on the outer side of the front of the carriage 0. The several QR codes corresponding to the tie rods 3 are respectively located on the outer side of the carriage 0 corresponding to each tie rod 3. QR codes are also provided at the rear and front of the carriage 0 to facilitate the sampling mechanism 4 in conjunction with the control system to determine its location.
[0037] Combination Figure 6 QR codes are affixed to the rear, tie rod, and head of the carriage. During equipment sampling, when the industrial camera scans the QR code information, it records the global coordinates of the current trolley. For example, when the QR code at the rear of the carriage is recognized, the global coordinates of the trolley are S1, the global coordinates of tie rod one are S2, the global coordinates of tie rod two are S3, and the global coordinates of the head of the carriage are S4. Therefore, the carriage length L = S4 - S1; the distance from tie rod one to the rear of the carriage = S2 - S1; and the distance from tie rod two to the rear of the carriage = S3 - S1.
[0038] Furthermore, this embodiment also proposes a method for identifying the location of vehicle tie rods, including: Preparation before sampling: Set up a QR code on the outside of the carriage 0, and ensure that the setting position of the corresponding identification piece 1 of the tie rod 3 is consistent with the position of the tie rod 3 inside the carriage 0. Set up corresponding QR codes at the rear and head of the carriage 0 respectively. Sampling area scanning: The control system controls the sampling mechanism 4 to move to the sampling point. The industrial camera 2 simultaneously scans the area where the sampling head descends to check if there is a QR code corresponding to the tie rod 3. If there is a QR code corresponding to the tie rod 3, the system avoids the tie rod 3 in that area, thus preventing the sampling head from being damaged.
[0039] Based on the above embodiments, if the QR code corresponding to the tie rod 3 is recognized in this embodiment, the industrial camera 2 acquires the width L1 of the tie rod 3 stored in the QR code and transmits it to the control system. The control system calculates the horizontal distance L = L1 / 2 + L3 + L2 that the sampling mechanism 4 needs to move based on the preset horizontal distance L3 of the outer edge protection of the tie rod 3 and the horizontal distance L2 between the sampling head and the center of the tie rod. After the control system controls the sampling mechanism 4 to move to the safe area in combination with the horizontal distance L, the sampling head descends to complete the sampling. In this embodiment, L3 can be 5-10cm, preferably 6cm. It should be noted that the value of L2 can be positive or negative. When the sampling head is between the front of the vehicle and the center of the tie rod, the value of L2 is negative. When the sampling head is between the rear of the vehicle and the center of the tie rod, the value of L2 is positive. The horizontal distance L2 between the sampling head and the center of the tie rod is calculated by the existing visual algorithm.
[0040] Based on the above embodiments, this embodiment requires the vehicle model information to be entered into the control system before sampling begins. This includes the license plate number, vehicle body length, vehicle body width, chassis height, and brace width. The control system controls the moving distance of the sampling mechanism 4 according to the entered information, and can move to the area where the next sampling point is located with relatively accurate accuracy.
[0041] The identification method proposed in this invention can monitor in real time whether there are tendons in the sampling area during the sampling process.
[0042] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
