[0002] Dogs' excellent sense of smell has long been used by humans. In a dog's nose, there are 300 million odor receptors, which allows some dogs to be trained to detect bombs, drugs, guns, gas and people. Sniffer dogs are now widely used in police dogs, such as drug detection dogs, but they are less used in the detection and rescue of gas leaks and fire. Authorization announcement number CN110024709B discloses a method for using a gas sniffer dog training facility. The device is mainly used for training gas sniffer dogs, filling the gap in gas sniffer dog training at home and abroad; it provides a complete set of facilities for gas sniffer dog training, with thoughtful details and good training effects.

[0003] The above patent mainly uses a complete set of facilities to enable sniffer dogs to sniff gas. However, when sniffer dogs are actually used in gas detection, multiple gases need to be identified.

[0014] The training method of the gas sniffer dog natural gas and biogas identification training equipment, the training steps are as follows: Step 1: First of all, choose the Beagle, Basset Hound, German Shepherd, and Black and Tan Coonhound. These four breeds have a calm temperament, a keen sense of smell, and strong trainability. Step 2: When the puppies of the selected breed are in the nursing period, they need to be carefully cared for. During the 3-4 months period, it is the best learning period for puppies. In the early stage, a larger setting is selected to separate the natural gas training ground and the biogas training ground, so that the puppies can get familiar with the smell and make preliminary identification, and let the puppies do preliminary running and movement exercises, so as to achieve the movement coordination training and basic obedience of the puppies. Step 3: When the puppy reaches 5 months old, the obedience of the puppy can be further strengthened, and the puppy can be trained to sit, stand and lie down according to the action memory. When the basic training meets the requirements, the instructor will interact with the designated smell through the action of the instructor to form a memory pattern of smell and action, and conduct training work on two fixed gases; Step 4: When the puppies are 5-9 months old, the action training and smell training are mainly targeted at the puppies, and gradually reinforced so that the puppies' sensitivity to smells reaches the specified requirements. Gas leakage points are simulated in separate training grounds. According to the training progress, single or multiple gas leakage points are opened to let the puppies find them independently, so as to conduct point exploration of the two gases and multi-point pursuit training in a 4-month cycle. When the accuracy rate reaches 90%, the puppies can complete the familiarization mode of natural gas and biogas respectively, and proceed to the next step of training; Step 5: When the puppies are between 9 and 12 months old, set up a mixed training room of natural gas and biogas, and set up obstacles to allow the puppies to sniff and identify the gas points.

Step 6: Set up a training room with adjustable gas leakage position to train the location and concentration of gas leakage. In actual training, adjust the location of natural gas or biogas leakage and let the sniffer dog search for it within a specified time. The concentration of gas discharge is adjusted from high to low. The sniffer dog is gradually made to identify and search for odors more sensitively. This training mode is a long-term training mode, which allows the sniffer dog to conduct in-depth training operations. Step seven: During the orientation training, using the action memory mode, while training the sniffer dogs to perform orientation sniffing, the sniffer dogs can demonstrate actions according to the concentration displacement after finding the designated points, so as to cooperate with the interaction of the staff, and let the sniffer dogs identify the concentration while identifying and searching for the odor, and feedback to the training staff, so as to achieve the identification of natural gas and biogas and point search, and finally carry out the concentration sniffing training mode. After passing the training in these modes, they can graduate to become sniffer dogs that can actually work.

In the setting environment of the directional training mechanism, it is convenient to carry out effective training on the directional location of gas leakage, thereby enhancing the sensitivity and reaction rate of sniffer dogs to gas sniffing, so that sniffer dogs can be used freely even in more harsh environments.

[0016] 2. The present invention utilizes the orientation training structure of the orientation training mechanism, which is not only convenient for assisting the sniffer dog to move and positionally sniff the orientation of the gas leakage, but also can adjust the gas leakage concentration, so that the sniffer dog can use body movements to give feedback according to the gas orientation and concentration, so as to cooperate with the instructions of the trainer, conduct more in-depth training for the sniffer dog, improve the orientation recognition and concentration identification efficacy of the sniffer dog training, and improve the application value of the sniffer dog in the field of gas detection.

During the training work, The natural gas or biogas is opened independently or simultaneously, and the sniffer dog is confused by the multiple installation holes 617 and looks for the gas outlet according to the instruction of the trainer. The servo motor 610 is started to drive the gear set 611 to mesh, forcing the rotating rod 609 to drive the rotating disk 603 to rotate as a whole, so as to change the direction of gas discharge. The sniffer dog is asked to find the gas outlet at a specified time, and the sniffer dog's direction identification function is trained. After sniffing the specified point, the sniffer dog interacts with the trainer by using the remembered body movements according to the concentration of the gas emission, so as to identify the concentration of the gas flowing out of the sniffing point, so as to allow the sniffer dog to carry out more in-depth and difficult training operations, and improve the accuracy and value of the sniffer dog working in different environments.

10. A training method for a gas sniffer dog natural gas and biogas identification training device, comprising the gas sniffer dog natural gas and biogas identification training device according to any one of claims 1 to 9, wherein the training method comprises the following steps: Step 1: First of all, choose the Beagle, Basset Hound, German Shepherd, and Black and Tan Coonhound. These four breeds have a calm temperament, a keen sense of smell, and strong trainability. Step 2: When the puppies of the selected breed are in the nursing period, they need to be carefully cared for. During the 3-4 months period, it is the best learning period for puppies. In the early stage, a larger setting is selected to separate the natural gas training ground and the biogas training ground, so that the puppies can get familiar with the smell and make preliminary identification, and let the puppies do preliminary running and movement exercises, so as to achieve the movement coordination training and basic obedience of the puppies. Step 3: When the puppy reaches 5 months old, the obedience of the puppy can be further strengthened, and the puppy can be trained to sit, stand and lie down according to the action memory. When the basic training meets the requirements, the instructor will interact with the designated smell through the action of the instructor to form a memory pattern of smell and action, and conduct training work on two fixed gases; Step 4: When the puppies are 5-9 months old, the action training and smell training are mainly targeted at the puppies, and gradually reinforced so that the puppies' sensitivity to smells reaches the specified requirements. Gas leakage points are simulated in separate training grounds. According to the training progress, single or multiple gas leakage points are opened to let the puppies find them independently, so as to conduct point exploration of the two gases and multi-point pursuit training in a 4-month cycle. When the accuracy rate reaches 90%, the puppies can complete the familiarization mode of natural gas and biogas respectively, and proceed to the next step of training; Step 5: When the puppies are between 9 and 12 months old, set up a mixed training room of natural gas and biogas, and set up obstacles to allow the puppies to sniff and identify the gas points. Under the guidance of the trainer, the puppies who have undergone memory training will find the designated leaking natural gas or biogas points. When the long-term accuracy rate reaches 90%, the odor identification training of the sniffer dogs can be ended, and when they reach one year old, the puppies will be successfully upgraded to sniffer dogs. Step 6: Set up a training room with adjustable gas leakage position to train the location and concentration of gas leakage. In actual training, adjust the location of natural gas or biogas leakage and let the sniffer dog search for it within a specified time. The concentration of gas discharge is adjusted from high to low. The sniffer dog is gradually made to identify and search for odors more sensitively. This training mode is a long-term training mode, which allows the sniffer dog to conduct in-depth training operations. Step 7; During the orientation training, the action memory mode is used to train the sniffer dogs to perform orientation sniffing. According to the different concentration displacements, the sniffer dogs can demonstrate actions according to the concentration displacement after finding the designated points, so as to cooperate with the interaction of the staff, and let the sniffer dogs identify the concentration while identifying and searching for the odor, and feedback to the training staff, so as to achieve the identification of natural gas and biogas and point search, and finally carry out the concentration sniffing training mode. After passing the training in these modes, they can graduate to become sniffer dogs that can actually work.
