Abstract
Description
Technical Field
[0001] The invention relates to animal training equipment, in particular to a small animal group warning reaction practical equipment for drug detection and bomb search, which is mainly suitable for training animal group reaction. Background Art
[0002] Existing drug-sniffing animals are primarily drug-sniffing dogs, commonly used in large venues like airports and train stations. They can quickly sniff out suspicious items in bags and luggage. However, the popularity of online shopping has driven rapid growth in the logistics industry, but this has also created security risks. Due to the lack of effective oversight mechanisms at some logistics companies, criminals exploit gaps in inspections and send illegal items through express delivery without verification. Identifying problematic packages through a comprehensive screening process among hundreds of millions of packages has become a nearly impossible task. Summary of the Invention
[0003] The purpose of the present invention is to provide a practical equipment for group warning response of small animals for drug detection and explosive search, which fundamentally solves the above problems. It utilizes the sensitive sense of smell of rodents and, after training, makes them produce conditioned reflexes to specific odors and perform specific behaviors, thereby achieving the purpose of quickly screening packages one by one. It has the advantages of simple and compact structure, low maintenance cost, easy transportation, fast recognition speed, and high recognition accuracy.
[0004] To achieve the above objectives, the present invention provides the following technical solutions: The small animal drug and bomb search group warning response practical equipment includes a mobile workstation, a vehicle-mounted control center, a cage assembly located in the mobile workstation, and a conveyor belt assembly. The technical key points are:
[0005] The onboard control center includes a human-computer interaction screen and a control chassis;
[0006] The conveyor belt assembly includes a conveyor belt body, a steering device arranged at intervals on the conveyor belt body, and a loading platform respectively arranged at the inlet end and the outlet end of the conveyor belt;
[0007] The squirrel cage assembly includes a working area and a living area connected by a connecting passage;
[0008] The working area includes a side working area arranged outside the book conveyor belt body and a middle working area located on the conveyor belt body, and the middle working area is provided with a rest platform;
[0009] The side working area is divided into four length-adjustable detection areas by a movable partition. Reward devices are provided on both sides of the movable partitions. The reward devices include a trigger, a driver and a reward tank.
[0010] The middle working area includes two detection areas separated in the middle, support rods respectively limited in the two detection areas, and a pull ring with a retractable traction rope slidably limited on the support rod. The end of the support rod is provided with a pressure sensor for receiving the tension of the pull ring;
[0011] The living area is located directly above the working area. It includes the squirrel cage body, a fresh air device, a feeding device, and a drawer-type feces collection trough arranged at the bottom of the squirrel cage body. The fresh air device is located on the side of the squirrel cage body, and its air inlet is located on the side wall of the mobile workstation box. A heating device is provided on its exhaust outlet.
[0012] Furthermore, the feeding device in the living area includes a water storage tank, a food storage tank, and a feeding trough.
[0013] The feeding trough adopts a double-layer structure; the upper layer is connected to the discharge port of the food storage tank, and a turntable structure driven by a motor is set at the outlet of the food storage tank. The signal input end of the motor is provided with a control circuit that sends a driving signal according to the set time. One end of the turntable is connected to the food storage tank, and the other end of the turntable is connected to the upper layer of the feeding trough; the lower layer is connected to the water storage tank through a conduit, and an electromagnetic valve is set on the conduit.
[0014] The beneficial effects of this invention include: The overall technical solution integrates the animal living area and work area within a mobile workstation on a mobile vehicle. The entire sorting process is monitored and controlled in real time via a human-machine interactive screen and control center located within the cab. Furthermore, when using a small vehicle for convenient transportation, without compromising overall functionality, a deployable cargo box flap and a stretchable cage structure are employed. The cage retracts inward during transport and fully expands upon arrival, maximizing space utilization. This not only makes the overall structure more compact but also reduces operational and maintenance costs.
[0015] To facilitate the survival and transportation of small animals, a living area has been set up inside the vehicle. When not in operation, the animals are kept in this area, equipped with a fresh air system, heating system, and feeding device, allowing the animals to survive unsupervised. Furthermore, to ensure a comfortable living environment, a skylight with an adjustable sunshade has been added to the existing structure.
[0016] The work area is connected to the living area by a pipe. It includes a side work area for sniffing packages from the sides and a top work area for sniffing packages from the top. The side work area is divided into four or more inspection zones by movable partitions. The four sides of each package are sniffed one by one in conjunction with the steering device on the conveyor body.
[0017] In order to determine whether the small animal has exhibited the specific behavior required after training, the image of the small animal is obtained in real time through the camera, and the image is sent to the on-board control center, and compared with the recognition data in the database that has been trained in advance through machine learning to obtain the final judgment result.
[0018] In summary, it has the advantages of simple and compact structure, high accuracy, and convenient and quick use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following combination Figures 1 to 5 , the contents of the present invention are described in detail through specific embodiments.
[0025] Example 1
[0026] The small animal drug control and bomb search group warning response practical equipment mainly includes a mobile workstation 4, a vehicle-mounted control center 3, a squirrel cage component 1 located in the mobile workstation 4, and a conveyor belt component 2.
[0027] The vehicle control center 3 includes a human-computer interaction screen and a control chassis. A touch screen can be used as the human-computer interaction interface, or an external keyboard or mouse can be connected to the control chassis to achieve human-computer interaction; the control chassis is used to store image recognition data, output control instructions to each component, and receive feedback signals from each component.
[0028] The conveyor belt assembly 2 includes a conveyor belt body 24, steering devices 23 arranged at intervals on the conveyor belt body 24, an inlet end loading platform 21 and a screening section loading platform 22 respectively arranged at the inlet and outlet ends of the conveyor belt; through the several steering devices 23 arranged on the conveyor belt, when the inspected package reaches a specific position, it rotates 90°, thereby realizing a comprehensive inspection of the side of the logistics package.
[0029] By modifying the rear storage area of the mobile workstation 4, the cage assembly 1 can be completely stored within the rear cargo box of the mobile workstation 4. The cage assembly 1 includes a work area 11 and a living area 12 connected by a connecting passage 13. The living area 12 is located directly behind the cab, and the work area 11 is located below the living area 12. When not in operation, animals are guided into the living area 12; when in operation, they are guided into the work area 11.
[0030] The work area 11 consists of a side work area 111 located outside the main body of the conveyor belt 24 and a central work area 112 located above the main body of the conveyor belt. The central work area 112 is equipped with a resting platform 112b, which is located outside the rat cages in the living area for ease of installation. Three movable partitions are installed within the side work area 111, dividing it into four sections. These partitions, combined with the steering device 23, are used to inspect the four sides of packages and ultimately convey clear packages to the diversion conveyor 7. The movable partitions can be used to guide rodents from the living area 12 to their desired work locations and to adjust the length of the work area 11 to match the steering device 23 on the conveyor belt and the sniffing habits of different rodents. The side work area 111 is divided into four adjustable detection zones by the movable partitions 111b. Reward devices 113 are located on both sides of the movable partitions 111b to provide positive motivation for animal training. The reward device 113 may include a reward storage tank 113a for storing food, a trigger 113b (such as an infrared sensor) set at a specific position, a driver (such as a driving motor), and a food drop trough 113c.
[0031] In order to detect the specific behaviors of rodents in an unmanned state, a camera 114 is set at the end of each detection section. During pre-training, a certain animal behavior is used as a judgment indicator. For example, taking squirrels as an example, when they find a suspicious package, they are trained to quickly change from a standing position to a prone position and maintain it for a long period of time, and the prone position is used as a specific behavior. The specific behaviors of the side working area 111 mainly include lying down and sticking to the cage after smelling a specific odor. For the above-mentioned specific behaviors, the outlines corresponding to the main viewing angles should be recorded, such as the main view, rear view, left view, and right view. A certain number of squirrel pictures of different body sizes should be used as training data, and the recognition accuracy is gradually corrected in a machine learning manner. In order to further improve the accuracy, pictures from other angles other than the above-mentioned viewing angles can also be added.
[0032] The main functions of the cameras in the side areas include the following: directly monitoring the activities of rodents through the display screen in the cab, and when encountering a slacking squirrel, it should be replaced in time; automatically identifying the specific movements of squirrels, and cooperating with the reward device and rotating mechanism to screen out problem packages; identifying the distance of the squirrel relative to the standard point. When it is at the end of the cage, that is, the origin, the camera records the size of its outline at this time. When it moves away from the camera toward the reward device, its outline size is positively correlated with the movement distance, from which the position of the squirrel in the work area can be inferred.
[0033] After the camera recognizes the mouse's specific behavior, the mouse reaches the trigger 113b in a short time. The trigger is set according to a similar trigger method used in pre-training. When the trigger 113b receives the mouse signal, it drives the motor to drop the food in the reward tank 113a into the food trough 113c, thereby completing the feedback process.
[0034] The central working area 112 includes two detection zones separated by a central portion, a support rod 112c positioned within each detection zone, a pull ring 112d with a retractable traction rope 112f that is slidably positioned on the support rod 112c, and a pressure sensor at the end of the support rod 112c for receiving the tension of the pull ring 112d. The central working area 112 does not contain a rat cage; the range of movement of rats is limited solely by the support rod 112c, the pull ring 112d that is slidably positioned on the support rod 112c, and the retractable traction rope 112f that connects the pull ring 112d to the rats. The retractable traction rope 112f preferably uses a coil spring as the power source for its retraction. Pressure sensors are also installed at the mounting points between the support rod 112c and the inner wall of the cargo box to prevent rats from becoming entangled and suffocating during the package screening process.
[0035] Specific behaviors in the middle area can include pulling on the rope, lying on the package with forelimbs, and staying on top of the package for a long time. For camera recognition in this area, the camera can be fixed on the top of the inner wall of the car box, and the time the squirrel lies on the box can be used as the identification standard for specific behaviors.
[0036] The living area 12 is located directly above the working area 11. It includes a cage body 121, a fresh air device 122, a feeding device 123, and a drawer-type feces collection trough arranged at the bottom of the cage body 121. The fresh air device 122 is located on the side of the cage body 121, and its air inlet is located on the side wall of the box body of the mobile workstation 4. A heating device is provided on its air outlet. In order to ensure that the rats do not feel uncomfortable during the transportation of the entire device in the non-working state and adapt to the environment in which they are located, the top of the living area 12 is set as a glass canopy that communicates with the outside world, and an extendable sunshade is used to adjust the incident light. At the same time, to ensure the stability of its living environment, a fresh air device 122 and a temperature sensor are also provided. The air inlet of the fresh air device 122 is connected to the outside world, and a heating device is provided on the air outlet of the fresh air device 122 to ensure a constant temperature environment in the living area 12.
[0037] The feeding device 123 includes a water tank 123a, a food tank 123b, and a feeding trough 123c. The feeding trough 123c adopts a double-layer structure; the upper layer is connected to the discharge port of the food tank 123b, and a motor-driven turntable structure is set at the outlet of the food tank 123b. One end of the turntable is connected to the food tank 123b for food supply, and the other end of the turntable is connected to the upper layer of the feeding trough 123c for food extraction. By timing the rotation of the motor, the timed quantitative supply of food can be achieved; the lower layer is connected to the water tank 123a via a conduit. By setting a solenoid valve on the conduit and controlling the opening time of the solenoid valve, the timed quantitative supply of drinking water can be achieved. In summary, the feeding device 123 can be used for automatic timed quantitative feeding of food and drinking water. It adopts a structure similar to the prior art, and the figure is omitted.
[0038] Taking the rectangular package as an example, during screening, the squirrels are placed in each work area through food induction or artificial means, that is, a "4+2" structure of four side work areas and two middle work areas, and the conveyor belt is started.
[0039] When a package is screened as problem-free, the sorter places the package on the inlet loading platform 21. The package enters the conveyor belt main body 24, with side I facing side work area I. The squirrels in work area I follow the package and sniff it. Driven by the steering device 23, the package rotates 90°, with side II facing side work area II (for the curved conveyor belt main body 24, due to the friction of the conveyor belt, the package's side II will always face side work area II). The package rotates another 90° under the action of the corresponding steering device 23, then enters side work area III and side work area IV, respectively, with side III and side IV corresponding to their respective sides. As the package travels, squirrels in the two zones of the central work area simultaneously sniff the package from above. When the squirrels in each zone show a specific reaction, the package is directed to the drainage conveyor belt 7 by the terminal steering device 23 and enters the subsequent sorting process.
[0040] When screening problematic packages, a detection threshold can be set through the onboard control center. Specifically, if more than 50% of the six sniffing squirrels show a specific reaction, the package is considered suspicious. When it reaches the end of the conveyor belt 24, it is directly directed to the screening end loading platform 22. If the number of squirrels showing a specific reaction falls below the set threshold, it can be determined as either an error or a suspicious package and diverted to other sorting areas.
[0041] Example 2
[0042] Furthermore, based on the technical solution of Example 1, to reduce manufacturing and maintenance costs, a small truck is preferably used. However, its load capacity and internal cargo space are limited, making it unable to fully accommodate the entire device. Therefore, it needs to be modified. Specifically, the two side walls of the cargo box adopt a flap structure, and the cage is converted to a plug-in structure. This allows the cage on one or both sides to be extended outward after the cargo box flap is opened, thereby expanding the usable space.
[0043] The steering device 23 of the conveyor belt assembly 2 mentioned herein can employ a structural design similar to the technical solution disclosed in application publication number CN110548684A. This solution employs a technical solution with 12 roller motor modules. By adapting this solution to the steering device 23 of the present invention, the number of roller motor modules can be reduced to a certain extent, as long as the package to be inspected on the conveyor belt body 24 is rotated 90° after reaching the designated area.
