Description

Technical Field

[0001] This invention belongs to the field of police dog training systems, specifically an automated training system for police dogs' ability to search for scents. Background Technology

[0002] Using police dogs' sense of smell for scent searching is one of the two main uses of police dogs: olfaction and attack. In China, over 60% of working dogs perform olfactory tasks. Before undertaking this task, police dogs require extensive training. Effective scent searching training is the core of olfactory training for police dogs. Traditional training methods, primarily led by the handler, involve: 1) manually selecting and placing a target (e.g., drugs, explosives); 2) manually guiding the dog to search for and identify the target; 3) manually compelling the dog to perform an alert action (e.g., sit, lie down, or bark) when it finds the target; and 4) manually releasing or rewarding the dog with food, a small object, or a toy. At least these four steps are required to complete one training session. Police dogs need to undergo 20 sessions daily for eight weeks to develop the ability to search and alert. Each dog requires a dedicated handler for continuous training to meet operational requirements.

[0003] However, this traditional training method has several drawbacks: long training cycle, high human input, passive reactions from the police dog during the alerting phase that affect its operational enthusiasm, and non-standard reward dog techniques. Furthermore, in the traditional training method, only the fourth reward dog phase involves the use of a remote-controlled catapult device to reward the police dog, which is still a method of deep human involvement, and there are problems with non-standard rewards due to differences in the timing and technique of the reward.

[0004] To address the problems raised in the background art, those skilled in the art have proposed an automated training system for police dogs' scent-searching abilities. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an automated training system for police dogs' scent-searching abilities, which solves the problems of long training time, low efficiency, and high cost in existing technologies for police dogs, as well as the lack of standardization in training methods.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 7 As shown:

[0028] This invention provides an automated training system for police dogs' scent-searching abilities, comprising: a cabin 31, and a protective door 32 rotatably mounted on the cabin 31 for use in combination with the training system; a base 9 and a support frame 8, and a functional frame 1 fixedly mounted on the base 9 for overall support; a scent generating mechanism mounted on the functional frame 1 for scent generation and induction during police dog training; a driving mechanism mounted within the functional frame 1 for driving the police dog during training; a connecting mechanism mounted between the functional frame 1 and the support frame 8 for connecting and driving the police dog training device; and a shaping mechanism slidably mounted on the support frame 8 for shaping the police dog during training.

[0029] By providing conditional automatic rewards to police dogs, key elements in scent-searching training for police dogs have been addressed. This enables training of police dogs to search behaviors in near-unattended conditions. The positive reinforcement method employed makes the police dogs more active during operations. At the same time, it enables unattended automatic training, prevents dogs from developing passive reactions, and integrates training with the police dogs' living scenarios. This can significantly improve training efficiency, shorten the training cycle, and save labor costs and expenses.

[0030] Meanwhile, eight latex blocks 7 and support frames 8 are evenly distributed on the floor and walls inside the cabin 31 to train police dogs to detect and alert to the scents of special items (including but not limited to drugs, explosives, etc.). During each training session, special items are placed in any four to five of the functional scent openings 12, and reward dog food 19 is placed in the food scent opening 13. No special items or reward dog food 19 are placed in the remaining functional scent openings 12 and food scent opening 13. When the police dog smells the special item, it presses its jaw against the food bait box 14 to receive a reward. The dog is rewarded with food (19). However, when the police dog does not smell the drug, it cannot get the reward by pressing its jaw against the food bait box (14). Based on the principle of conditioned reflex, after repeated attempts, the police dog will understand that it can only get the reward by pressing its jaw against the food bait box (14) and lying down to warn when it smells the special scent. This gradually enables the police dog to develop the ability to smell special items and warn. Multiple identical latex blocks (7) and support frames (8) and other structural devices, whether they emit the scent of special items, become the basis for the police dog to warn. The conditioned reflex of searching for the scent of special items is thus established.

[0031] refer to Figure 1 , Figure 2 and Figure 6 The odor generating mechanism includes a feeding box 11, a functional odor port 12, a food odor port 13, a transmission rod 10, and a food attractant box 14;

[0032] A feeding box 11 is fixedly connected to the side wall of the functional frame 1, allowing the functional frame 1 to hold dog food 19 for use as a reward for police dog training. A functional scent port 12 is provided on the side of the feeding box 11, allowing simulated scents of drugs and explosives to be placed inside the functional scent port 12 to train the police dog to recognize scents. A food scent port 13 is provided on the side wall of the functional frame 1 above the feeding box 11, and dog food 19 is placed inside the food scent port 13. This allows the dog food 19 inside the food scent port 13 to enhance the police dog's ability to judge the location of the food reward, making it easier to quickly identify the location of the feeding box 11.

[0033] Meanwhile, a transmission rod 10 is rotatably connected to the outer wall of the functional frame 1, and a food bait box 14 is fixedly connected to the transmission rod 10. When the police dog is conducting scent search training, after smelling the scent of a special item in the functional scent port 12, it can press the food bait box 14 under its chin to rotate the transmission rod 10 to remind and alert the dog, and at the same time make a "lie down" posture to remind the dog that there is a special item. In addition, after the food bait box 14 is pressed, dog food 19 will fall into the feeding box 11, which is a reward for the police dog's "lie down" warning.

[0034] In addition, a feeding compartment 29 is provided inside the food bait box 14, allowing dog food 19 to be loaded inside the food bait box 14. Several scent leakage holes 28 are provided on the top of the food bait box 14, penetrating the interior of the food bait box 14. This allows the dog food 19 loaded inside the food bait box 14 to release its scent through the scent leakage holes 28. A magnetic sealing plate 30 is attached to the side of the food bait box 14, which magnetically seals the feeding compartment 29 to prevent the dog food 19 from leaking out from the side of the food bait box 14 and facilitates the replacement of the dog food 19. In this way, when the police dog smells the scent of a dangerous substance in the functional scent port 12 and needs to press the food bait box 14 to rotate the transmission rod 10 to get the food, the dog food 19 inside the food bait box 14 also emits an inducing scent, prompting the police dog to press the food bait box 14 with its chin to rotate the transmission rod 10, which facilitates training the police dog to perform the "lie down" command as a warning.

[0035] Example 2:

[0036] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The drive mechanism includes a rotating rod 23, a transmission rack 21, a storage bin 18, a limiting sealing plate 22, and a transmission cavity 24;

[0037] By rotatably connecting a rotating rod 23 inside the functional frame 1 and fixing the rotating rod 23 to the transmission rod 10, when the food bait box 14 is pressed down by the police dog, the rotating rod 23 will rotate downward through the transmission rod 10. A transmission gear 21 is rotatably connected to the side wall of the rotating rod 23, so that the transmission gear 21 can also be driven to move downward.

[0038] Meanwhile, a storage bin 18 is fixedly connected inside the functional frame 1, allowing dog food 19 to be loaded into the storage bin 18. A limit sealing plate 22 is rotatably connected to the inner wall of the functional frame 1, enabling the limit sealing plate 22 to rotate and seal the bottom of the storage bin 18. A transmission gear 20 is rotatably connected to the inner wall of the functional frame 1, and the transmission gear 20 is fixedly connected to the limit sealing plate 22, so that when the transmission gear 20 rotates, the limit sealing plate 22 also rotates. In addition, the outer wall of the transmission gear 20... The transmission rod 10 and the rotating rod 23 are engaged with the transmission rack 21, so that when the food reward box 14 is pressed by the police dog, the transmission rod 10 and the rotating rod 23 will rotate and drive the transmission rack 21 to move downward. At this time, the transmission rack 21 will engage and drive the transmission gear 20 to rotate, so that the limiting sealing plate 22 will rotate with the transmission gear 20, loosening the seal on the bottom of the storage bin 18, so that the dog food 19 loaded in the storage bin 18 can be guided through the transmission cavity 24 to the discharge port 16, and finally fall into the feeding box 11, achieving the purpose of rewarding the police dog.

[0039] Secondly, a spring 25 is fixedly connected between the transmission cavity 24 and the rotating rod 23. Since the transmission cavity 24 is a fixed structure, the rotating rod 23 is elastically pulled by the spring 25, keeping it in a similar raised state. This facilitates the downward pressing of the food bait box 14 during police dog training. A second spring 26 is fixedly connected between the transmission gear 21 and the storage bin 18. Since the storage bin 18 is a fixed structure, the transmission gear 21 is elastically pulled by both the second spring 26 and the first spring 25, forming a dynamic equilibrium state. When the food bait box 14 is pressed downwards, it will cause the rotating rod 23 to rotate downwards. The moving rod 23 drives the transmission rack 21 to move downwards. After the food attractant box 14 is pressed, the transmission rack 21 will be pulled back to the predetermined position by the second spring 26 and the first spring 25. In addition, a third spring 27 is fixedly connected between the storage bin 18 and the limiting sealing plate 22, so that the limiting sealing plate 22 is elastically pulled by the third spring 27 to keep the bottom of the storage bin 18 sealed. When the transmission rack 21 does not rotate the limiting sealing plate 22, the limiting sealing plate 22 will resume sealing the bottom of the storage bin 18 under the elastic pull of the third spring 27 to prevent the dog food 19 from leaking out.

[0040] Example 3:

[0041] refer to Figure 2 and Figure 3 The connecting mechanism includes a receiving frame 2, a fixed pulley 3, a traction rope 4, and a receiving hook 5;

[0042] By fixing a support frame 2 between the functional frame 1 and the support frame 8, the support frame 2 can be used as a support between the functional frame 1 and the support frame 8. A support hook 5 is elastically rotatably connected inside the support frame 8, and a traction rope 4 is fixedly connected between the top of the support hook 5 and the top of the transmission rack 21, so that when the transmission rack 21 moves downward, the support hook 5 can be rotated by the traction rope 4.

[0043] Meanwhile, a fixed pulley 3 is rotatably connected to the receiving frame 2, so that the traction rope 4 can pass through the fixed pulley 3 during the rotation and sliding process. The fixed pulley 3 provides rotational assistance, which makes the sliding transmission of the traction rope 4 smoother and less labor-intensive, and can prevent excessive wear between the traction rope 4 and the receiving frame 2.

[0044] refer to Figure 2 and Figure 3 The shaping mechanism includes a connecting bracket 6, a latex pressing block 7, a limiting slider 17, and a limiting groove 15;

[0045] A latex pressure block 7 is slidably connected to the inner wall of the support frame 8, and two limiting grooves 15 are symmetrically opened on the inner wall of the support frame 8. Two limiting sliders 17 are symmetrically fixedly connected to the side wall of the latex pressure block 7, and the limiting sliders 17 and the limiting grooves 15 are slidably connected, so that the latex pressure block 7 can slide on the inner wall of the support frame 8.

[0046] Meanwhile, a connecting bracket 6 is fixedly connected to the top of the latex block 7, and the top of the connecting bracket 6 is engaged and limited to the bottom of the receiving hook 5. When the police dog is undergoing scent training, after the police dog presses the food bait box 14 with its chin, the transmission of the rotating rod 23 and the transmission gear 21 will cause the leash 4 to pull the receiving hook 5 to rotate, causing the receiving hook 5 to release the engagement and limitation of the connecting bracket 6, thereby allowing the latex block 7 to slide down and press against the back of the police dog. This trains the police dog to complete the "lie down" action, so that the police dog's body is in a "lie down" posture for warning, and no human intervention is required, achieving the purpose of standardized procedure.

[0047] Working principle: A feeding box 11 is fixedly connected to the side wall of the functional frame 1, allowing the functional frame 1 to hold dog food 19 for use in police dog training and rewards. A functional scent port 12 is provided on the side of the feeding box 11, allowing simulated scents of substances such as drugs and explosives to be placed inside, for training police dogs to recognize scents. A food scent port 13 is provided on the side wall of the functional frame 1 above the feeding box 11, and dog food 19 is placed inside the food scent port 13, allowing the dog food 19 inside the food scent port 13 to be... To enhance the ability to pinpoint the location of food rewards for police dogs and facilitate quick identification of the feeding box 11, a storage bin 18 is fixedly connected inside the functional frame 1, allowing dog food 19 to be loaded into the storage bin 18. A limit sealing plate 22 is rotatably connected to the inner wall of the functional frame 1, enabling the limit sealing plate 22 to rotate and seal the bottom of the storage bin 18. A transmission gear 20 is also rotatably connected to the inner wall of the functional frame 1, and the transmission gear 20 is fixedly connected to the limit sealing plate 22, so that when the transmission gear 20 rotates, the limit sealing plate 22 also moves... The transmission gear 20 is rotated, and its outer wall meshes with the transmission rack 21. When the food reward box 14 is pressed by the police dog, the transmission rod 10 and rotating rod 23 rotate, causing the transmission rack 21 to move downwards. At this time, the transmission rack 21 meshes with the transmission gear 20, causing the limiting sealing plate 22 to rotate along with the transmission gear 20, loosening the seal on the bottom of the storage bin 18. This allows the dog food 19 loaded in the storage bin 18 to be guided through the transmission cavity 24 to the discharge port 16, finally falling into the feeding box 11, thus rewarding the police dog. The purpose is twofold: firstly, a connecting bracket 6 is fixedly connected to the top of the latex block 7, and the top of the connecting bracket 6 is engaged and limited to the bottom of the receiving hook 5. This allows the police dog to perform scent training. When the police dog presses the food bait box 14 with its chin, the rotation rod 23 and the transmission gear 21 will cause the leash 4 to pull the receiving hook 5 to rotate, causing the receiving hook 5 to release the engagement and limitation of the connecting bracket 6. This allows the latex block 7 to slide down and press against the back of the police dog, thereby training the police dog to complete the "lie down" action without human intervention, achieving the goal of standardized procedures.
