Description

Technical Field

[0001] The present invention relates to the technical field of cargo detection, and in particular to a cargo identification and detection system for a highway green channel. Background Art

[0002] Green Pass cargo inspection refers to the process of rapid inspection and quarantine of vehicles transporting fresh agricultural products (such as vegetables, fruits, meat, aquatic products, etc.) under the green channel policy. The green channel policy aims to promote the rapid circulation of fresh agricultural products, reduce logistics costs, and ensure food safety. The main inspection item of the existing green pass cargo inspection is the freshness of the goods, that is, the goods that have not been deeply processed. For example, freshly produced wet garlic belongs to green pass goods, while processed dry garlic does not belong to green pass goods. The existing green pass cargo inspection is judged by scanning the goods and the staff's observation of the external goods. It is impossible to detect the freshness of the internal goods. However, when vehicles are transporting goods such as vegetables and fruits for long distances, due to long-term exposure to sunlight and the action of external wind, the goods outside the vehicle will show signs of drying, resulting in the staff being unable to accurately judge the goods. The driver needs to unload the external goods to facilitate the inspection of the internal goods. This inspection method will waste a lot of time and reduce the inspection efficiency of green pass goods. Summary of the invention

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] Existing Green Pass cargo inspection usually relies on scanning the cargo and staff's observation of the external cargo to make judgments. However, this method cannot detect the freshness of the internal cargo. When transporting goods such as vegetables and fruits over long distances, the cargo outside the vehicle may be dried due to long-term exposure to the sun and external wind, which makes it difficult for staff to accurately judge the overall condition of the cargo. Therefore, the driver is often required to unload the external cargo in order to inspect the internal cargo. This inspection method wastes a lot of time and reduces the inspection efficiency of Green Pass cargo.

[0045] A highway green channel cargo identification and detection system, such as Figure 1 and Figure 2 As shown, it includes: a cargo identification platform 1, which is provided with a management center; a scanning device 2, which is arranged on the cargo identification platform 1 and is used to scan whether there are interlayer cargoes inside the vehicle, a cargo identification device 3 is arranged on the top of the scanning device 2, and the cargo identification device 3 is used to detect whether the cargo is green pass cargo, a weighing device 4 is arranged on the cargo identification platform 1, and the weighing device 4 is used to detect the cargo weight of the vehicle, a license plate recognition device 5 is arranged on the cargo identification platform 1, and the license plate recognition device 5 is used to recognize the license plate of the vehicle, and a blocking fence 6 is arranged on the cargo identification platform 1, and the blocking fence 6 is used to remind the vehicle to stop or start, and the scanning device 2, the cargo identification device 3, the weighing device 4, the license plate recognition device 5 and the blocking fence 6 are all connected to the management center through a transmission module; a manual detection platform 7, which is arranged on the cargo identification platform 1, and the manual detection platform 7 is spline-connected with a thorn sampling tube 8; a labor-saving component, which is arranged on the manual detection platform 7, and the labor-saving component is used to assist manual sampling.

[0046] In the above scheme, the management center can realize license plate recognition, vehicle information collection, fee calculation and data analysis. The scanning device 2 can adopt X-ray scanning equipment. X-rays can penetrate metal and non-metal materials, display the internal structure of the vehicle, and generate detailed images to facilitate the identification of internal interlayers and goods. The cargo identification device 3 is a high-definition camera device, which is used to take pictures and identify green pass goods, and transmit them to the management center for comparison with the green pass cargo database to determine whether they are green pass goods. The license plate recognition device 5 is used to take pictures of the vehicle's license plate information and transmit it to the management center to ensure that the green pass information is the same as the vehicle charging information, and calculate the charging amount. The manual detection platform 7 is a multi-axis adjustment device and can slide along the cargo identification platform 1 to facilitate the adjustment of the height and deflection angle of the piercing sampling tube 8 thereon, that is, to change the sampling position of the piercing sampling tube 8.

[0047] Specifically, Figure 2 and Figure 4As shown, the labor-saving component includes: a handle 201, which is slidably connected to the manual detection platform 7, the manual detection platform 7 is connected to a first gear 202 for limited rotation, the handle 201 is spline-connected to the first gear 202, the manual detection platform 7 is connected to a second gear 203 for limited rotation, the first gear 202 is meshed with the second gear 203, and the second gear 203 is threadedly connected to the puncture sampling tube 8.

[0048] In the above scheme, the first gear 202 and the second gear 203 drive the piercing sampling tube 8 to be inserted into the goods by rotating the handle 201, and the piercing linear motion of the staff's hand is changed to a hand-cranked rotational motion, which reduces the staff's force torque and saves effort. When the external goods are dried and cannot be judged, the piercing sampling tube 8 is used to pierce and sample the internal goods to detect the internal goods, avoid loading and unloading inspection of the goods, greatly shorten the inspection time, and improve the inspection efficiency.

[0049] When the vehicle enters the cargo identification platform 1, the vehicle passes through the scanning device 2. At this time, the scanning device 2 will scan the entire vehicle body and transmit the scanned image to the management center, and the staff will determine whether there are interlayer cargoes inside the vehicle. When the vehicle drives above the weighing device 4, the weighing device 4 will measure the weight of the vehicle body and transmit it to the management center to determine whether the vehicle's load has reached more than 80% of the marked load. At this time, the cargo identification device 3 photographs the type and condition of the cargo placed on the vehicle, so that the staff can further determine whether the green pass has been processed. Then the license plate recognition device 5 recognizes the license plate and transmits it to the management center. Then, the fee is calculated based on the distance between the entry station and the exit station and whether the green pass meets the requirements. After the fee is charged, the blocking fence 6 is opened to release the vehicle.

[0050] When the goods on the outside of the long-distance transportation appear to be air-dried, it is necessary to inspect the goods inside the vehicle. At this time, the staff pulls the manual inspection platform 7 to the inspection position, and then adjusts the direction of the piercing sampling tube 8 through the manual inspection platform 7 so that the piercing sampling tube 8 faces the goods. At this time, the staff turns the handle 201, and the handle 201 drives the first gear 202 to rotate, so that the first gear 202 drives the second gear 203 to rotate, thereby driving the piercing sampling tube 8 to slide along the manual inspection platform 7, so that the piercing sampling tube 8 is gradually inserted into the goods. At this time, the goods gradually enter the interior thereof as the piercing sampling tube 8 is inserted, and this is done until the piercing sampling tube 8 reaches the required depth. Then the staff stops turning the handle 201, and then turns the handle 201 in the opposite direction so that the handle 2 01 The piercing sampling tube 8 is driven to reset through the first gear 202 and the second gear 203 until the piercing sampling tube 8 is separated from the cargo. Then the staff observes whether the cargo near the inlet end of the piercing sampling tube 8 is in normal condition. Then the cargo remaining inside the piercing sampling tube 8 is taken out, the detection position is changed, and the above steps are repeated again. This cycle is repeated three to five times to improve the accuracy of the staff in judging whether the cargo is green-passed (the above-mentioned behavior detection will cause damage to some cargo. When performing the above-mentioned detection, the driver's consent is required. If the driver disagrees, the driver is required to perform unloading inspection in accordance with regulations). By performing piercing sampling on the internal cargo to detect the internal cargo, it is possible to avoid loading and unloading inspection of the cargo, which greatly shortens the inspection time and improves the inspection efficiency.

[0051] In a further embodiment, Figure 2-Figure 4 As shown, it also includes: a cutting component, which is arranged on the piercing sampling tube 8 and is used to cut off the material that has not completely entered the piercing sampling tube 8. The cutting component includes: a swivel 301, the swivel 301 is rotatably connected to the piercing sampling tube 8, the swivel 301 is provided with a circumferentially distributed first slide groove 302, the piercing sampling tube 8 is slidably connected with a circumferentially distributed spring 303, and the circumferentially distributed spring 303 are respectively slidably connected with adjacent first slide grooves 302; a guide ring 304, which is fixedly connected to the inside of the swivel 301, and the guide ring 304 is used to guide and bend all the springs 303; a driving component, which is arranged on the manual detection platform 7, and the driving component is used to drive the guide ring 304 to rotate; the radius of the swivel 301 is greater than the radius of the piercing sampling tube 8, which is used to reduce the contact area between the piercing sampling tube 8 and the goods; the cross-section of the guide ring 304 is L-shaped, which is used to bend the spring 303 by 90°.

[0052] In the above scheme, an arc-shaped triangular block is provided on the rotating ring 301 to reduce the resistance of the piercing sampling tube 8 to insert into the goods. The first slide groove 302 is circumferentially evenly distributed on the rotating ring 301. The first slide groove 302 is a spiral groove. The reed 303 is a metal sheet, which is elastic and can be bent. The rotation of the rotating ring 301 drives the reed 303 to squeeze the guide ring 304, so that the reed 303 is deflected 90° along the guide ring 304 by the squeezing force, and the goods are cut off to ensure that the goods inside the piercing sampling tube 8 can be taken out, thereby improving the judgment accuracy of the staff. The radius of the rotating ring 301 is larger than the radius of the piercing sampling tube 8, so that there is a gap between the piercing sampling tube 8 and the goods, reducing the resistance to the insertion and removal of the piercing sampling tube 8.

[0053] Specifically, Figure 3 and Figure 4 As shown, the driving component includes: a gear ring 305, which is connected to the manual detection platform 7 for limiting rotation, a telescopic shaft 306 is fixedly connected between the rotating ring 301 and the gear ring 305, and the telescopic shaft 306 is used to adapt to the change of the distance between the gear ring 305 and the rotating ring 301, and the handle 201 is fixedly connected to the third gear 307, and the third gear 307 is in transmission cooperation with the gear ring 305; a limiting component is arranged on the manual detection platform 7, and is used to prevent the gear ring 305 from rotating.

[0054] In the above scheme, the telescopic shaft 306 is located within the maximum radius of the rotating ring 301. During detection, the telescopic shaft 306 is located in the gap between the piercing sampling tube 8 and the cargo, reducing the detection resistance of the piercing sampling tube 8. At the same time, the telescopic shaft 306 adapts to the position change between the rotating ring 301 and the gear ring 305, so that the gear ring 305 is in a fixed state, which is convenient for the staff to connect the third gear 307 with the gear ring 305, thereby improving the convenience of the staff's operation.

[0055] Specifically, Figure 4 As shown, the limit assembly includes: a first limit shaft 308, which is slidably connected to the manual detection platform 7 through a connecting piece, the first limit shaft 308 and the gear ring 305 are limited and matched, and a first elastic piece 309 is arranged between the first limit shaft 308 and the connecting piece.

[0056] In the above scheme, the first limit shaft 308 locks the toothed ring 305 when the piercing sampling tube 8 is inserted into the cargo and pulled out, so as to prevent the toothed ring 305 from rotating at will and causing the circumferentially distributed reed leaves 303 to extend prematurely. The first elastic member 309 is a spring, and the first elastic member 309 is used to drive the first limit shaft 308 to reset.

[0057] After the staff drives the piercing sampling tube 8 to insert to the required depth, when pulling out the piercing sampling tube 8, the goods at the entrance end of the piercing sampling tube 8 may still be adhered to the goods in the vehicle and cannot be taken out along with the piercing sampling tube 8, resulting in less goods being taken out by the piercing sampling tube 8, affecting the staff's judgment. When the piercing sampling tube 8 reaches the required depth, the staff pulls the first limiting shaft 308 and the first elastic member 309 is compressed at the same time, so that the first limiting shaft 308 is separated from the gear ring 305, and the limit of the two is released. Then the staff pushes the handle 201, and the handle 201 is separated from the first gear 202. At the same time, the handle 201 drives the third gear 307 to dock with the gear ring 305. Then the staff turns the handle 201, and the handle 201 drives the third gear 307 to rotate. The third gear 307 rotates synchronously through the gear ring 305 and the telescopic shaft 306, so that the telescopic shaft 306 drives the swivel 301 to rotate, and the swivel 301 drives the first slide groove 302 distributed circumferentially thereon to rotate. 02 drives the adjacent spring pieces 303 to slide along the piercing sampling tube 8, and the spring pieces 303 are bent 90° toward the central axis of the piercing sampling tube 8 by the guide ring 304, so that the circumferentially distributed spring pieces 303 contact each other with the central axis of the piercing sampling tube 8, and the adhered goods are cut off at the same time, and then the staff stops pulling the first limiting shaft 308. At this time, the first elastic member 309 resets and drives the first limiting shaft 308 to limit the gear ring 305 again, and then the staff pulls the handle 201 to make The handle 201 drives the first gear 202 to dock, and drives the third gear 307 to separate from the gear ring 305, and then resets and rotates the handle 201 to drive the piercing sampling tube 8 to separate from the goods, and this continues until the piercing sampling tube 8 is completely pulled out, and the circumferentially distributed reed 303 is pushed and bent 90° under the action of the guide ring 304, so that the circumferentially distributed reed 303 can cut off the adhered goods, ensuring that all the goods entering the piercing sampling tube 8 can be taken out, thereby improving the judgment accuracy of the staff.

[0058] After the staff pulls out the piercing sampling tube 8, the staff pulls the first limiting shaft 308 again to release the limiting of the toothed ring 305, and then makes the toothed ring 305 dock with the third gear 307 again, and resets the rotating ring 301, so that the rotating ring 301 is separated from each other through the circumferentially distributed spring leaves 303 and resets to the initial state, and then stops pulling the first limiting shaft 308, restores the limiting of the toothed ring 305 by the first limiting shaft 308, and resets the handle 201 at the same time, so that the toothed ring 305 is separated from the third gear 307. When sampling and testing of the goods is needed again, repeat the above steps.

[0059] In a further embodiment, Figure 4-Figure 8As shown, it also includes: a material guide component, which is arranged in the piercing sampling tube 8 and is used to push the material into the piercing sampling tube 8. The material guide component includes: a rotating ring 401, which is rotatably connected to the piercing sampling tube 8, and the rotating ring 401 is fixedly connected with a material guide plate 402, and the material guide plate 402 is a spiral plate, which is used to push the material in the piercing sampling tube 8; an insertion shaft 403, which is slidably connected to the inside of the piercing sampling tube 8, and a second slide groove 404 is arranged on the rotating ring 401. The insertion shaft 403 is fixedly connected with a clamping shaft 405, and the clamping shaft 405 is slidably connected to the second slide groove 404, and a second elastic member 406 is arranged between the insertion shaft 403 and the piercing sampling tube 8; a pushing component, which is arranged on the manual detection platform 7, and the pushing component is used to make the insertion shaft 403 slide along the piercing sampling tube 8.

[0060] In the above scheme, the rotating ring 401 is located in the middle of the piercing sampling tube 8, and the guide plate 402 is located on the side close to the rotating ring 301. The guide plate 402 is used to guide the material entering the piercing sampling tube 8 inwardly. The second slide groove 404 consists of a spiral groove and a vertical groove. The spiral groove and the vertical groove are close to a docking point of the rotating ring 301. A metal spring sheet for unidirectionally limiting the clamping shaft 405 is provided, which is used to allow the clamping shaft 405 to enter the spiral groove from the vertical groove to avoid returning along the original path of the vertical groove. The second elastic member 406 is a spring. The second elastic member 406 is used to drive the insertion shaft 403 to reset. By making the guide plate 402 rotate periodically, the goods are guided to the inside of the piercing sampling tube 8, leaving space for the goods that enter the piercing sampling tube 8 later, reducing the resistance of the goods entering the piercing sampling tube 8, increasing the sampling content of the piercing sampling tube 8, and improving the judgment accuracy of the staff.

[0061] Specifically, Figure 4 , Figure 5 and Figure 8 As shown, the pushing component includes: a second limit shaft 407, which is slidably connected to the manual detection platform 7, a third elastic member 408 is arranged between the second limit shaft 407 and the manual detection platform 7, and the plug-in shaft 403 is fixedly connected with a linear array of sawtooth blocks 409, and the linear array of sawtooth blocks 409 are all squeezed and matched with the second limit shaft 407; the elastic coefficient of the third elastic member 408 is greater than the elastic coefficient of the second elastic member 406.

[0062] In the above scheme, the second limit shaft 407 is provided with symmetrically distributed inclined surfaces, the third elastic member 408 is a tension spring, and the third elastic member 408 is used to push the second limit shaft 407 to reset. The sawtooth block 409 has an inclined surface that matches the inclined surface of the second limit shaft 407. The sawtooth blocks 409 are evenly spaced on the insertion shaft 403 and are used as scales to remind the staff of the insertion depth of the piercing sampling tube 8. Through the mutual extrusion of the sawtooth block 409 and the second limit shaft 407, the insertion shaft 403 slides along the piercing sampling tube 8, and then drives the guide plate 402 to rotate periodically through the clamping shaft 405 and the second slide groove 404.

[0063] When the staff turns the handle 201 to push the piercing sampling tube 8 into the cargo, the piercing sampling tube 8 drives the insertion shaft 403 to move synchronously, and the insertion shaft 403 drives the sawtooth block 409 of the linear array on it to contact the second limiting shaft 407. At this time, the second limiting shaft 407 blocks the insertion shaft 403 from continuing to move synchronously with the piercing sampling tube 8 through the sawtooth block 409, and the insertion shaft 403 starts to slide along the piercing sampling tube 8, and the insertion shaft 403 drives the clamping shaft 405 on it to move along the spiral of the second slide groove 404. The second elastic member 406 is compressed, and the card shaft 405 drives the rotating ring 401 to rotate through the second sliding groove 404, and the rotating ring 401 drives the guide plate 402 to rotate synchronously, so that the rotation of the guide plate 402 guides the goods to the inside of the piercing sampling tube 8, and provides space for the goods that subsequently enter the piercing sampling tube 8 to flow out, so that the card shaft 405 slides along the spiral groove of the second sliding groove 404 to the vertical groove. At this time, the card shaft 405 can no longer move, and the piercing sampling tube 8 passes through the rotating ring The second slide groove 404 on 401 pulls the card shaft 405, so that the card shaft 405 drives the sawtooth block 409 on the plug shaft 403 to squeeze the second limit shaft 407. At this time, the second limit shaft 407 slides along the manual detection platform 7 under the squeezing force of the adjacent sawtooth block 409, and the third elastic member 408 is stretched. Then the second elastic member 406 is reset and drives the plug shaft 403 to reset and slide along the piercing sampling tube 8. At the same time, the plug shaft 403 drives the card shaft 405 thereon to slide along the straight groove of the second slide groove 404. The guide plate 402 is rotated periodically to guide the goods to the inside of the piercing sampling tube 8, leaving space for the subsequent goods entering the piercing sampling tube 8, reducing the resistance of the goods entering the piercing sampling tube 8, increasing the sampling content of the piercing sampling tube 8, and improving the judgment accuracy of the staff, until the piercing sampling tube 8 reaches the required depth.

[0064] When the piercing sampling tube 8 needs to be pulled out, the staff rotates the handle 201 in the opposite direction to pull out the piercing sampling tube 8. At this time, the piercing sampling tube 8 drives the rotating ring 401 and the insertion shaft 403 to move synchronously. At this time, the insertion shaft 403 drives the sawtooth block 409 thereon to reset synchronously. When the sawtooth block 409 contacts the second limit shaft 407, the sawtooth block 409 directly squeezes the second limit shaft 407 to slide along the manual detection platform 7, and the third elastic member 408 is stretched. When the sawtooth block 409 is separated from the second limit shaft 407, the third elastic member 408 is reset and drives the second limit shaft 407 to reset. This cycle is repeated until the piercing sampling tube 8 is separated from the cargo and restored to the initial state. When the cargo needs to be inspected again, the above steps are repeated.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
