Description

Technical Field

[0001] The invention belongs to a dog training device, and in particular relates to a comprehensive training device and a training method for dogs to identify the smell of SF6 gas. Background Art

[0002] Sulfur hexafluoride (SF6) gas is an excellent gas insulating dielectric material and is widely used as an insulating medium for high-voltage / ultra-high-voltage electrical equipment. Gas-insulated metal-enclosed switchgear (GIS) is also called SF6 enclosed combination electrical equipment. Compared with open lines, GIS equipment has many advantages such as safe and reliable operation, less maintenance and small footprint. SF6 gas leakage in GIS equipment is a very common phenomenon. SF6 gas leakage monitoring devices need to be installed in workplaces with GIS equipment.

[0003] In the prior art, due to considerations of cost, simplicity, safety, etc., the SF6 gas leakage monitoring devices put into use on a large scale can only perform fixed-point detection. The pointer meter can only simply reflect the SF6 gas concentration and cannot respond to changes in the monitoring environment. There is no alarm function and it can only rely on manual inspection.

[0004] SF6 gas is a colorless, tasteless, odorless, non-toxic inert gas with a density heavier than air. Commonly used methods for detecting SF6 gas leaks include the soap bubble method, halide detector method, infrared radiation imaging method, and laser photoacoustic spectroscopy. Among them, the soap bubble method and halide detector method are easy to operate but require a lot of manpower and have low accuracy, and are easily affected by factors such as wind on site; infrared radiation imaging, gas infrared absorption, and laser photoacoustic spectroscopy are slightly more sensitive, but the cost is generally high, portable equipment has low accuracy, large errors, and is easily interfered with, and high-precision equipment is bulky and large and is not suitable for on-site detection. SF6 gas is usually presented in the form of "black smoke" in infrared imaging. Years of operating experience have shown that it is still difficult to find a simple, economical, fast and effective method for SF6 gas leakage detection in GIS equipment.

[0005] The utility model with announcement number CN207836480U discloses a combined device for dog odor identification and search training, which includes a search platform, a remote control food reward device, an exhaust device, an odor bottle, and an arc cover plate; the search platform is provided with an odor bottle placement slot; the odor bottle is placed on the odor bottle placement slot; a reward food slot is provided between two adjacent odor bottle placement slots; the arc cover plate is located directly above the search platform; the remote control food reward device is located above the reward food slot; the exhaust device includes an exhaust duct and an exhaust fan; the exhaust duct is provided with multiple exhaust ports; the exhaust port is located directly above the odor bottle; it is easy to disassemble, and the remote control food reward device is used, which not only minimizes the interference to the dog, but also helps to cultivate the dog's search form and work desire; the exhaust device is used, which helps to timely extract the residual odor in the air, avoiding interference with the dog's work. The training combined device adopts a manual method and can only be viewed on site, which cannot meet the current needs of increasingly automated training.

[0006] The influence of the smell identification training of detection dogs on their smell identification ability is almost decisive, but the smell identification training in China still relies on the traditional dog training method, which is inefficient and unstable. There is almost no detection dog smell identification training platform in China, and there is no systematic and platform-based automatic training device or method for detection dogs. Summary of the invention

[0028] The modules of the comprehensive training device for dog odor identification of SF6 gas include a training module for dog identification training, a live recording module for providing training site video, a verification module for infrared imaging of SF6 gas, and a remote conference module.

[0030] The training module includes an identification operation table 1, on which a plurality of identification tanks 2 filled with SF6 gas and air mixed gas of different concentrations are arranged. The gas is identified by smelling in the tank. The trainer can place a cloth adsorbed with SF6 gas or a professional odor tube as an odor source in an aluminum cylindrical odor identification tank, and manually open the tank body to allow the detection dog to identify and recognize. SF6 gas and its concentration can be identified in the form of "black smoke" in the infrared imaging screen. The judge observes the infrared imaging screen to determine whether the dog has identified correctly. The equipment provided by the present invention is mainly used to cultivate the olfactory sensitivity and accuracy of the detection dog to SF6 gas. The size of the identification operation table is set to 6.4m*1.6m*0.2m.

[0032] Example 2

[0033] This embodiment provides a method for training dogs using the comprehensive training device for identifying the smell of SF6 gas, comprising the following steps:

[0034] S1. Invite experts;

[0035] S2. Configure different identification tanks for gases, train personnel and dogs, and turn on cameras and infrared detectors;

[0036] S3. The trainer conducts scent identification training on the dog. The camera transmits the captured images to the local server and cloud server in real time for viewing by mobile terminals. The infrared detector performs infrared real-time imaging and synchronously verifies the training results.

[0037] S4. The remote conference system simultaneously displays live images and infrared images on a large display screen for observation and comparison. Experts conduct discussions, evaluations, interactions, assessments, and comprehensive evaluations of training results.

[0038] During training, the gas configuration scheme for identifying the gas in the tank is to set up multiple groups of mixed gases of SF6 gas and air with different concentrations for odor recognition training: a mixed gas of SF6 gas and air with a higher concentration is used to simulate the situation when SF6 gas leaks seriously (SF6 gas accounts for more than 1% of the volume of the gas in the bottle); a mixed gas of SF6 gas and air with a lower concentration is used to simulate the situation when SF6 gas leaks slightly (SF6 gas accounts for less than 1% and more than 0.5% of the volume of the gas in the bottle); normal air is used to simulate the situation when GIS equipment is operating normally and SF6 gas has not leaked (SF6 gas accounts for less than 0.5% of the volume of the gas in the bottle). The above air is the sampling gas of the actual use place of GIS equipment. A standardized odor collection procedure is carried out in the place where the detection dog is required, such as using an odor collector to sample gas near the flange connection of the GIS equipment in the outdoor substation, strictly controlling the gas sampling method and time, ensuring the balance of odor during the gas collection process, and reducing errors.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
