Technical Field
[0001] This invention relates to the field of police dog equipment technology, specifically to a visual reinforcement training device for sniffing behavior suitable for local dog breeds. Background Technology
[0002] Sniffing is one of the most important working abilities of police dogs. Currently, the police working dog breeds widely used in China are mainly imported breeds, including German Shepherds, Springer Spaniels, Labrador Retrievers, Belgian Malinois, and Rottweilers. Among my country's native dog breeds, some breeds such as the Xiasi Dog, Kunming Dog, and Linzhi Dog have been proven in practice to have the potential and ability to serve as police dogs. Long-term observation and systematic research have revealed significant differences in snipping behavior between native dog breeds with police dog potential and the aforementioned common police working dog breeds. These differences manifest in two aspects: First, influenced by their adaptation to their original living environment, native breeds exhibit a stronger tendency for independent exploration and relatively weaker obedience to commands. When exposed to traditional closed identification containers, they are prone to distraction or alternative exploration behaviors, affecting their snipping focus. Second, the snipping rhythm of native breeds exhibits a "high-frequency, short-duration" characteristic, with a single sniff lasting approximately 1.2 seconds, while the snipping rhythm of common police working dog breeds is mostly a "low-frequency, long-duration" pattern, with a single sniff lasting 1.5 seconds or more. This difference makes it more difficult to capture effective sniffing moments in native breeds. These differences in snipping behavior characteristics make it difficult to implement precise and intensive training for native breeds using traditional police dog snipping training methods. This can easily lead to the solidification of incorrect snipping patterns, thereby restricting the standardized training and widespread application of native breeds in snipping-related police work. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned technology and provide a training device that can enhance the sniffing duration of native dog breeds.
[0004] To address the aforementioned technical problems, the present invention proposes the following technical solution: a visual reinforcement training device for sniffing behavior suitable for native dog breeds, comprising: a sniffing box and a reward box; the sniffing box has a perforated partition in the middle dividing it into an upper and lower part, the upper part of the sniffing box is open and the side walls are made of transparent material, and the side walls have size scales drawn from top to bottom; the lower part of the sniffing box can accommodate a scent source and is provided with an air inlet, and an airflow detection device is arranged at the air inlet; the reward box is arranged next to the sniffing box; the reward box can hold food or toys and has an openable cover on the top.
[0005] A further improvement to the above solution is that: the airflow detection device is a flip cover covering the air inlet; the flip cover contacts a tactile switch; when there is an airflow into the sniffing box at the air inlet, the flip cover is deflected by the airflow, thereby changing the state of the tactile switch; the tactile switch is connected to a timer.
[0006] A further improvement to the above scheme is that the airflow detection device is an impeller arranged at the air inlet. When the airflow direction of the air inlet is towards the sniffing box, the impeller rotates clockwise. When the airflow direction of the air inlet is towards the sniffing box, the impeller does not rotate or rotates counterclockwise. The output of the impeller is connected to a timer.
[0007] A further improvement to the above solution is that an interference box is arranged on the outside of the sniffing box; the interference box can contain the interfering odor source and has several breathable openings on its surface.
[0008] A further improvement to the above solution is that the timer is connected to a processor, and the cover plate on top of the reward box is opened and closed by the processor via an electromagnetic switch.
[0009] A further improvement to the above solution is that at least two cameras facing the sniffing box are arranged on the upper outer side of the sniffing box.
[0010] A further improvement to the above solution is that: several through-beam sensors are arranged from top to bottom on the upper inner side of the sniffing box; each through-beam sensor is evenly arranged at a 1cm interval along the height direction, and each through-beam sensor is connected to the processor.
[0011] A further improvement to the above solution is that the upper inner side of the sniffing box is coated with an anti-fog coating.
[0012] This invention provides a visual reinforcement training device for sniffing behavior in native dog breeds. Through a transparent sniffing box and high-contrast scale markings, trainers can better distinguish between effective sniffing and superficial exploration, reducing erroneous reinforcement due to misjudgment. Placing the reward box close to the sniffing box ensures that reinforcement is highly synchronized with effective sniffing behavior, significantly enhancing positive reinforcement and promoting rapid solidification of the target sniffing pattern. Furthermore, this device can simulate real-world sniffing environments of varying complexity using external interference boxes, achieving a smooth transition from basic training to real-world simulation. Combined with progressive training scenario construction, it conforms to the principles of operant conditioning, effectively improving the stability and anti-interference ability of dog sniffing. Experimental data shows that the interference suppression ability of the experimental group using this device was 52.1% higher than that of the control group (p < 0.01). Attached Figure Description

[0017] Example 1: This example describes a visual reinforcement training device for snipping behavior suitable for native dog breeds, such as... Figure 1 and Figure 2 As shown, it includes: a sniffing box 1 and a reward box 1a. The sniffing box 1 has a perforated partition in the middle dividing it into an upper and lower part. The upper part of the sniffing box 1 is open, with transparent sidewalls. The sidewalls have dimensional markings drawn from top to bottom, and the inner side of the sidewalls is coated with an anti-fog coating. At least two cameras 3 facing the sniffing box 1 are arranged on the outer side of the upper part of the sniffing box 1. Several through-beam sensors are arranged from top to bottom on the inner side of the upper part of the sniffing box 1. Each through-beam sensor is evenly arranged at a 1cm interval along the height direction. The lower part of the sniffing box 1 can accommodate the odor source and has an air inlet 2. Figure 3 As shown, an airflow detection device is arranged at the air inlet 2; the airflow detection device is a flip cover 2a covering the air inlet 2; the flip cover 2a contacts a tactile switch 2b. The outside of the sniffing box 1 also has an interference box 4; the interference box 4 can contain interfering odor sources and has several ventilation openings on its surface.
[0018] like Figure 2 As shown, the reward box 1a is fan-shaped and can be inserted into the gap between the sniffing box 1 and the interference box 4. The lid 1b of the reward box 1a opens inward and is locked by an electric pin. The lid 1b has a handle 1c for pulling up the lid 1b to close it again. The reward box 1a is used to hold rewards such as treats for the police dog.
[0019] Camera 3 is also housed in the gap between sniffing box 1 and jamming box 4, and the gap is protected by a cover plate. The cover plate is also a fan-shaped cover plate to avoid obstructing reward box 1a. Several reward boxes 1a can be arranged at once in the gap as needed.
[0020] The tactile switch 2b and the through-beam sensor are both connected to the processor through necessary circuits; the electric pin of the reward box 1a can be controlled by the processor through necessary circuits, or it can be triggered by the trainee using a remote control, and each reward box is triggered independently.
[0021] A training scent source is placed at the bottom of the sniffing box 1, and a reward is placed in the reward box 1a and installed in the gap. All components are activated. Depending on the size of the police dog, different sniffing depth standards are used. The most basic mode involves the trainer checking the sniffing depth against the scale on the sniffing box 1 and estimating the sniffing time to check if the dog's sniffing duration is up to standard. If it is, the electric pin on the reward box 1a is opened via remote control, and the lid 1b of the reward box 1a opens under gravity, allowing the police dog to obtain the reward. This method relies heavily on the trainer's subjective observation, and its accuracy varies greatly; it is only intended as a basic training method.
[0022] When conditions permit, an automatic mode can be used. The trigger depth of the photosensitive sensor can be set according to the dog's size. That is, if the photosensitive sensor at the standard depth point is triggered, the sniffing depth is considered sufficient. When the dog sniffs, i.e., inhales, air enters the sniffing box through the air inlet. The flip cover 2a deflects due to the airflow, changing the state of the touch switch 2b from triggered to off. When the dog exhales or the airflow disappears, the flip cover 2a presses against the touch switch 2b under gravity, triggering it again. The processor times the off state; when it reaches 1.5 seconds, the sniffing time is considered sufficient. Both the sniffing depth and sniffing time must be achieved simultaneously. The processor then operates the electric pin of the reward box 1a to open it. Trainers replenish the gifts in the reward box 1a promptly.
[0023] Camera 3 is used to film the training process, and combined with the data recorded by the processor, it is used to study the police dog's sniffing depth and sniffing duration.
[0024] Example 2: This example describes a visual reinforcement training device for snipping behavior in native dog breeds. Example 2 is largely the same as Example 1, with differences such as... Figure 4 As shown, the airflow detection device is an impeller 2c arranged at the air inlet. When the airflow direction of the air inlet is towards the sniffing box, the impeller 2c rotates clockwise. When the airflow direction of the air inlet is towards the sniffing box, the impeller does not rotate or rotates counterclockwise. The impeller 2c is connected to the processor through a Hall effect detection circuit. The processor can then obtain the rotation information of the impeller 2c and thus obtain the sniffing time information of the police dog.
[0025] This invention is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this invention may have other implementation methods. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
