Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of working dog training equipment, and particularly relates to a working dog high-position search training system and a training method. BACKGROUND

[0002] In the working scenes of criminal investigation, tracking and hunting and public security patrol, it is often necessary to search for hidden evidence, explosives and criminal suspects in high-position areas. Artificial one-by-one checking not only consumes time and effort, but also has certain safety hazards, and through the sensitive olfactory of working dogs, searching and checking the target area with a certain height difference can greatly improve the search range and search efficiency.

[0003] At present, there are various types of working dog training equipment on the market, but few training supplies are specifically designed for high-position search. When conducting high-position search training, a simple platform is often temporarily set up or modified by using existing buildings, mountains and trees, which has the problems of unstable structure and inconvenient height adjustment, and it is difficult to meet the actual training needs, and at the same time, the safety of the training assistants cannot be effectively guaranteed. When rewarding the high-position search training, the reward is artificially assisted by the training instructors or training assistants, which easily interferes with the concentration of the dogs, and at the same time, it is easy to cause the dogs to produce false warning or error warning between the warning behavior and the specific action of the training instructors or training assistants. In order to solve the above problems, it is particularly necessary to design a working dog high-position search training system and a training method. SUMMARY

[0004] In view of the deficiencies in the prior art, the present application aims to provide a working dog high-position search training system and a training method, which realizes non-contact arbitrary change of target position in training, reduces human assistance in warning reward and diversifies the types of reward, and the reward device can be disassembled and combined, suitable for different training scenes.

[0005] In order to achieve the above purpose, the present application is realized by the following technical scheme: a working dog high-position search training system, comprising a cloud track, a mobile platform, a reward device and a remote controller; the cloud track is connected at the head and tail to form a closed loop, the cross section of the cloud track is an open rectangular, the planes on both sides of the opening are used as the support surface of the mobile platform, a plurality of mobile platforms are arranged below the cloud track, the reward device is connected below the mobile platform, and the remote controller is in control connection with the mobile platform and the reward device.

[0006] Preferably, the mobile platform includes a platform main frame, a container, container side panels, a reel support, a reel, a wire rope, a reel drive motor, a first battery, and a drive motor controller. The platform main frame has four wheels and four guide wheels on its sides. The bottom of the platform main frame is fixedly connected to the top of the container. A drive motor controller is located outside the container, and two symmetrical reel supports are located inside. The reel is fixed to the reel supports through shaft holes. The right end of the reel is fixedly connected to the output shaft of the reel drive motor. The reel drive motor is located on the first battery, which is fixed to the bottom of the container. A hole is provided on the bottom of the container, through which the wire rope fixed to the reel extends downwards. A ring is provided at the bottom of the wire rope.

[0007] Preferably, the reward device includes a reward device top cover, an odor box, an odor box cover, a hook, a reward device housing, a feeding stepper motor, a feeding blade, a second battery, a hinge, a reward device bottom cover, a bottom cover stepper motor, and a reward device controller. The top of the reward device top cover has an odor box fixed to it, with numerous small holes on its side. An odor box cover is located on top of the odor box, with a small hole in its center. The hook passes through the small hole and is directly fixed to the reward device top cover. The reward device top cover is threadedly connected to the reward device housing. The reward device housing consists of an upper cylinder and a lower tube. A feeding stepper motor is fixed to the center of the bottom surface of the upper cylinder. The output shaft of the feeding stepper motor is fixedly connected to the feeding blade, which divides the upper cylinder into eight compartments. A fan-shaped material drop hole is located at the bottom of the upper cylinder. A second battery is located at the top of the lower tube, and a reward device bottom cover is located at the bottom. The reward device bottom cover is connected to the lower tube via a hinge. The reward device controller and the bottom cover stepper motor are fixed to the side of the lower tube.

[0008] Preferably, the drive motor controller is equipped with a signal receiving module, which can receive signal commands from the remote control. The reel drive motor, the platform main frame, and the drive motor controller are electrically connected.

[0009] Preferably, the reward device controller is equipped with a signal receiving module, which can receive signal commands issued by the remote control. The feeding stepper motor and the lower cover stepper motor are electrically connected to the reward device controller.

[0010] Preferably, the output shaft of the stepper motor for the lower cover is bent at a 90° right angle.

[0011] A training method for high-position search dogs includes the following steps: 1. Before training, the reward device is lowered to the appropriate height by controlling the reel drive motor in the corresponding mobile platform with the remote controller, then different reward food is placed in the upper cylindrical compartment, and reward items are placed in the lower cylindrical tube. The target odor source is placed in the odor box. The target odor source, reward food, and reward items can be placed in the same reward device or in different reward devices. Then, the reward device is adjusted to the height of the training plan by the remote controller, and the mobile platform is moved to the appropriate position. 2. During training, after the working dog accurately locates the position of the target odor source and alerts, the trainer controls the feeding step motor in the corresponding reward device to work by using the remote controller, and the reward food in the upper cylindrical compartment will fall from the bottom of the cylinder through the feeding blade. To continuously reinforce the alert behavior of the dog, the reward food can be controlled to fall intermittently. The lower cover step motor can also be controlled to work by the remote controller, and the reward device cover will open under the action of gravity, so that the reward items in the lower cylindrical tube will fall freely. When the dog fails to find the target odor source or falsely alerts, the trainer does not give any reward, and the dog is taken away for a while to calm down before entering again or adjusting the training plan to lower the height of the target odor source. After completing the reward of one training, the trainer can take the dog away from the training area, then move the mobile platform on the rail by the remote controller, and adjust the height of the reward device to achieve non-contact transformation of the position of the target odor source, quickly adjust the training plan, and facilitate multiple training in a short time. 3. After training, the reward device is lowered by the remote controller, the target odor source is removed and placed back in its original position, the remaining reward food and reward items are removed, and then the reward device is cleaned and disinfected. After that, the reward device and the mobile platform are restored to their original positions by the remote controller.

[0012] As a preferred embodiment, step (1) further includes the following conditions when outdoor training is required: the reward device is removed from the bottom ring of the steel wire rope, different reward food is placed in the upper cylindrical compartment of the reward device, reward items are placed in the lower cylindrical tube, and the target odor source is placed in the odor box. The target odor source, reward food, and reward items can be placed in the same reward device or separately. Before training, the hook at the top of the reward device is suspended from a ladder, a clothes hanger, or other objects to a position such as a tree or a high building. When the working dog alerts and is rewarded, the trainer controls the corresponding feeding step motor and lower cover step motor to work by using the remote controller, so that the reward food and reward items fall from it.

[0013] Preferably, the placement of the target odor source, reward food, and reward item in step (1) includes four cases: a) the target odor source, reward food, and reward item are placed in the same reward device; b) the target odor source is placed in a separate reward device, and the reward food and reward item are placed in another reward device; c) the target odor source, reward food, and reward item are placed in three different reward devices; d) based on cases b and c, an interfering odor source is added, which can be one or more, and placed in the odor box of the remaining reward device. Among them, 'a' is used in the early stage of establishing working dogs' high-altitude search ability, where the target scent source is linked to the reward, establishing a connection that finding the target scent source will result in a reward, so that the dog will emotionally love the target scent; 'b' and 'c' are used in the stage of mastering working dogs' high-altitude search ability, strengthening the dog's scent connection with the target scent, reducing the influence of the scent of the reward or other items on the dog's alert behavior, and preventing the dog from alerting to the scent of the reward or other items instead of the target scent source; 'd' is used in the stage of consolidating and improving working dogs' high-altitude search ability, where the dog has already established a strong scent connection with the target scent, but the working environment in actual combat is complex and there are many interfering scents, so scent differentiation training is required to avoid false alerts.

[0014] The present invention has the following beneficial effects: The invention features a reasonable structural design, enabling non-contact lateral and longitudinal movement of the target position, thus improving training efficiency. The warning rewards are continuous and diverse, reinforcing warning behaviors. Rewards are dropped remotely, reducing human intervention and preventing undesirable associations. The reward device is detachable and combinable, suitable for various scenarios, highly practical, and easy to promote and use. Attached Figure Description

The drive motor controller 2-9 is installed on the outside of the container 2-2, and two symmetrical reel supports 2-4 are installed inside. The reel 2-5 is fixed to the reel support 2-4 through a shaft hole. The right end of the reel 2-5 is fixedly connected to the output shaft of the reel drive motor 2-7. The reel drive motor 2-7 is located on the first battery 2-8. The first battery 2-8 is fixed to the bottom surface of the container 2-2. A hole is provided on the bottom surface of the container 2-2, and the wire rope 2-6 fixed on the reel 2-5 extends downward through the hole. A ring is provided at the bottom of the wire rope.

[0019] It is worth noting that the reward device 3 includes a reward device upper cover 3-1, an odor box 3-2, an odor box cover 3-3, a hook 3-4, a reward device outer shell 3-5, a feeding stepper motor 3-6, a feeding blade 3-7, a second battery 3-8, a hinge 3-9, a reward device lower cover 3-10, a lower cover stepper motor 3-11, and a reward device controller 3-12; the odor box 3-2 is fixed to the top of the reward device upper cover 3-1, the odor box 3-2 has a large number of small holes on its side, the odor box cover 3-3 is set on the top of the odor box 3-2, the odor box cover 3-3 has a small hole in its center, and the hook 3-4 passes through the small hole and is directly fixed to the reward device upper cover 3-1. The reward device upper cover 3-1 is threadedly connected to the reward device outer shell 3-5; the reward device outer shell 3-5 is composed of an upper cylinder and a lower tube. A feeding stepper motor 3-6 is fixed at the center of the bottom surface of the upper cylinder. The output shaft of the feeding stepper motor 3-6 is fixedly connected to the feeding blade 3-7. The feeding blade 3-7 divides the upper cylinder into eight compartments. A fan-shaped material drop hole is opened at the bottom of the upper cylinder. A second storage battery 3-8 is installed at the top of the lower tube. A reward device lower cover 3-10 is installed at the bottom. The reward device lower cover 3-10 is connected to the lower tube through a hinge 3-9. A reward device controller 3-12 and a lower cover stepper motor 3-11 are fixed on the side of the lower tube.

[0020] It is worth noting that the drive motor controller 2-9 is equipped with a signal receiving module, which can receive signal commands issued by the remote controller 4. The scroll drive motor 2-7, the platform main frame 2-1 and the drive motor controller 2-9 are electrically connected.

[0021] It is worth noting that the reward device controller 3-12 is equipped with a signal receiving module, which can receive signal commands issued by the remote controller 4. The feeding stepper motor 3-6 and the lower cover stepper motor 3-11 are electrically connected to the reward device controller 3-12.

[0022] In addition, the output shaft of the lower cover stepper motor 3-11 is bent at a 90° right angle.

[0023] A training method for high-position search dogs includes the following steps: Before training, the remote controller 4 operates the scroll drive motor 2-7 in the corresponding moving platform 2 to lower the reward device 3 to a suitable height. Different rewards are then placed in the upper cylindrical compartment, and reward items are placed in the lower cylindrical tube. Simultaneously, the target odor source for training is placed in the odor box 3-2. The target odor source, rewards, and reward items can be placed in the same reward device 3 or in separate reward devices 3. Afterward, the remote controller 4 adjusts the reward device 3 to the planned training height, and then the moving platform 2 is moved to the appropriate position.

[0024] During training, once the working dog accurately locates the target scent source and gives an alert, the trainer uses remote control 4 to operate the feeding stepper motor 3-6 in the corresponding reward device 3. The reward in the upper cylindrical compartment will fall from the drop hole at the bottom of the cylinder, driven by the feeding blades 3-7. To continuously reinforce the dog's alert behavior, the reward can be controlled to fall intermittently. Alternatively, remote control 4 can be used to operate the lower cover stepper motor 3-11, causing the lower cover 3-10 of the reward device to open under gravity, allowing the reward inside the lower cylinder to fall freely. If the dog fails to find the target scent source or gives a false or incorrect alert, the trainer should not give any reward. Instead, the dog should be taken away to calm down and re-enter the training area, or the training plan should be adjusted by lowering the height of the target scent source.

[0025] After completing a training reward, the trainer can take the dog away from the training area and then use the remote control 4 to control the mobile platform 2 to move on the track 1 and adjust the height of the reward device 3 to achieve non-contact change of the target scent source location, quickly adjust the training plan, and facilitate multiple training sessions in a short period of time.

[0026] After training, the reward device 3 is lowered to a certain height using remote control 4, the target odor source is removed and returned to its original position, the remaining food and reward items are removed together, the reward device 3 is then cleaned and disinfected, and then the reward device 3 and the mobile platform 2 are restored to their original positions using remote control 4.

[0027] Step (1) also includes the following situation: when outdoor training is required, the reward device 3 can be removed from the bottom ring of the wire rope 2-6, different treats can be placed in the upper cylindrical compartment of the reward device 3, the reward item can be placed in the lower cylindrical tube, and the target scent source can be placed in the scent box 3-2. The target scent source, treats, and reward items can be placed in the same reward device or placed separately. Before training, the hook 3-4 at the top of the reward device 3 can be hung on a tree, a high place on a building, etc., using a ladder, clothes pole, or other items. When the working dog alerts and rewards, the trainer uses the remote control 4 to control the corresponding feeding stepper motor 3-6 and the lower cover stepper motor 3-11 to work, so that the treats and reward items fall from them.

[0028] In step (1), there are four main scenarios for the placement of the target odor source, reward food, and reward item: ① The target odor source, reward food, and reward item are placed in the same reward device; ② The target odor source is placed in a separate reward device, and the reward food and reward item are placed in another reward device; ③ The target odor source, reward food, and reward item are placed in three different reward devices; ④ Based on scenarios ② and ③, an interfering odor source is added. There can be one or more interfering odor sources, which are placed in the odor boxes of the remaining reward devices. ① is mainly used in the initial stage of establishing working dogs' high-altitude search ability, where the target scent source is linked to the reward, establishing a connection that finding the target scent source will result in a reward, making the dog emotionally fond of the target scent; ② and ③ are mainly used in the stage of mastering working dogs' high-altitude search ability, strengthening the dog's scent connection with the target scent, reducing the influence of the scent of the reward or other items on the dog's alert behavior, and preventing the dog from alerting to the scent of the reward or other items instead of the target scent source; ④ is mainly used in the stage of consolidating and improving working dogs' high-altitude search ability, where the dog has already established a strong scent connection with the target scent, but the working environment in actual combat is complex and there are many interfering scents, so scent differentiation training is required to avoid false alerts.

[0029] This specific embodiment of the working dog high-position search training system and method achieves efficient and flexible dog training through modular design. The system consists of a closed-loop track, a movable platform, an intelligent reward device, and a remote controller. The movable platform integrates a scroll lifting mechanism, and the reward device adopts a compartmentalized design to allow for multiple combinations of scent sources, treats, and reward items for delivery. The training method is divided into four stages: initial stage to establish scent-reward association, intermediate stage to strengthen scent recognition, later stage to reduce interference, and consolidation stage to incorporate interference source differentiation training. The system supports both indoor automatic track adjustment and outdoor manual suspension modes. Correct warning behaviors are reinforced by remotely controlling the intermittent dropping of treats or the free fall of reward items. It also features contactless changes to training scenarios and quick reset of training parameters, significantly improving training efficiency and environmental adaptability.
