The invention provides a smell training device. The smell training device comprises a storage device, an emitting device and a connecting part, wherein the storage device is used for storing OLFM; the emitting device is used for emitting OLFM; the connecting part is arranged between the storage device and the emitting device, each of two ends of the connecting part is provided with an opening, and the openings communicate with the storage device and the emitting device; a control valve is fixed in the connecting part in a sealed manner, and the control valve is a one-way valve, is opened when OLFM flows to the emitting device from the storage device through the connecting part, and is closed when OLFM flows to the storage device from the emitting device through the connecting part. The smell training device is suitable for smell training, and the invention aims at providing the smell training device which is reasonable in structure, easy and convenient to operate, and convenient to carry.

Images of farm animal products taken by CCD camera through image acquisition card are transferred to computer. Under certain condition (temperature, humidity and flow rate), smells emitted from farm animal products through mini pump with no oil are sucked into reaction chamber, where signals are generated by array of gas sensor. The said signals through conditioning circuit, A / D acquisition card are transferred to computer. Computer for simulating human brain to treat vision data and smell data carries out syncretizing and pattern recognition processing. Combining with experts' knowledge in knowledge base as well as experiences, computer makes judgment for qualities of garden spgarden stuff, meat and corns etc. synthetically.

The invention discloses a system and a method for testing acuity of sense of smell of animals. The system comprises a fixed cage device, a smell generating device, and a data acquiring and analyzing module; a size and volume adjustable space is arranged in the fixed cage device; the smell generating device comprises a smell generating box, an air chamber and a first air pipe; the data acquiring and analyzing module comprises a sensing electrode, a pre-posed amplifying circuit, a data acquiring module, and an analyzing module which are electrically connected in sequence; the analyzing module is further connected with a database module; cranial nerve electric information data of dogs is pre-stored in the database module; the sensing electrode is used for sensing the cranial nerve electric information of the dogs, wherein the cranial nerve electric information is amplified by the pre-posed amplifying circuit and then acquired by the data acquiring module; the analyzing module compares the collected cranial nerve electric information data of the dogs with the pre-stored data, so as to test the acuity of sense of smell of the dogs. The invention provides the system and the method capable of testing acuity of sense of smell of animals objectively and efficiently.
