The infrared body temperature detector 15 is used to detect the body temperature of a pig. Specifically, the infrared body temperature detector 15 is connected under the drone body 2 through a rotating connector.

Specifically, the terminal wireless communication device, the UAV wireless communication device 11, and the mobile terminal use a mobile network or a WIFI network for wireless communication.

S1, pig house 2 temperature and humidity detection: the temperature and humidity in pig house 2 are monitored through temperature sensors and humidity sensors, and the results are transmitted to the terminal controller. After the terminal controller analyzes the data, the central air conditioner is turned on or off The temperature and humidity in the pig house 2 are regulated, and the real-time information of the temperature and humidity in the pig house 2 is wirelessly transmitted to the mobile terminal;

Specifically, the temperature of pig house 2 is mainly two types, the temperature of piglet breeding and the temperature of big pig breeding;

The suitable environment temperature for newborn piglets at birth is 34.0℃, and afterwards it will drop by 2℃ every week, and it is advisable to be 22.0～25.0 at weaning. The piglets are in a constant temperature environment (39.0℃) in the mother's body, and the environment changes suddenly after birth. Thin, thin hair, less subcutaneous fat, relatively large body surface area, fast heat dissipation, and poor body temperature regulation ability, so piglets are afraid of cold; in winter, newborn piglets should be cut off the umbilical cord and must be moved into an incubator immediately after eating colostrum. The suitable environment temperature for big pigs is 10.0～20.0℃. If the temperature exceeds 35.0, heat stress will occur. The sweat glands of big pigs degenerate, the subcutaneous fat is thick, and the body heat is not easily dissipated through the body surface, so big pigs are afraid of heat. If the temperature is too high, in addition to ventilation and cooling, you can also spray water on the surface of the pig to cool it down.

Therefore, according to the growth stage of the pigs, it is necessary to adjust the temperature in the pig house 2 through the central air conditioner according to the feedback of the temperature sensor in the pig house 2 to meet different growth requirements.

S2, harmful gas detection in pig house 2: monitor the ammonia gas concentration, hydrogen sulfide concentration, carbon monoxide concentration, and carbon dioxide concentration in pig house 2 through ammonia sensors, hydrogen sulfide sensors, carbon monoxide sensors, and carbon dioxide sensors, and the results After the terminal controller analyzes the data, the terminal controller opens the electric doors and windows for ventilation, and cooperates with the central air conditioner to ventilate the pig house 2 to reduce the concentration of harmful gases, and real-time the concentration of harmful gases in the pig house 2 Information is transmitted wirelessly to the mobile terminal;

Specifically, ammonia gas mainly comes from the decomposition of feces. Ammonia is easily soluble in water. In pig house 2, ammonia is often dissolved or adsorbed on moist floors, walls and pig mucosa. Ammonia can stimulate mucosa and cause mucosal congestion. Laryngeal edema and bronchitis can cause pulmonary edema and pulmonary hemorrhage in severe cases; ammonia can also cause central nervous system paralysis, toxic liver disease, etc. Pigs are under the long-term effect of low concentration of ammonia, their physical fitness becomes weak, and they are sensitive to certain diseases This symptom is called “chronic ammonia poisoning”. If the ammonia concentration is high, it will cause obvious pathological reactions and symptoms to pigs, which is called “ammonia poisoning”. It is reported that the production performance of pigs begins to be affected when the volume concentration of ammonia in the air reaches 0.005% (50 ml/m3). At 0.01%, appetite is reduced and various respiratory diseases are prone to, and it causes shallow breathing and spasms at 0.03%. , The ammonia content of pig house 2 should generally be controlled within 0.003%;

Hydrogen sulfide is a colorless and volatile odorous gas. It is mainly derived from the decomposition of sulfur in pig house 2. Hydrogen sulfide is produced from the ground of pig house 2 and has a larger specific gravity. Therefore, the closer it is to the ground, the greater the concentration. Hydrogen sulfide mainly stimulates the mucous membranes, causing conjunctivitis, rhinitis, tracheitis, and even pulmonary edema. Frequent inhalation of low concentrations of hydrogen sulfide can cause autonomic nervous disorders. The hydrogen sulfide free in the blood can interact with oxidative cytochrome oxidase. The combination of ferric iron in the medium makes the enzymes inactive, which affects the oxidation process of cells, causing tissue hypoxia, long-term exposure to low-concentration hydrogen sulfide environment, pigs become weaker, disease resistance declines, high-concentration hydrogen sulfide It can directly inhibit the respiratory center and cause suffocation and death. When the concentration of hydrogen sulfide reaches 0.002%, it will affect the appetite of pigs. The concentration of ammonia sulfide in pig house 2 should not exceed 0.001%;

Carbon monoxide is a colorless and odorless gas. Generally, there is not much carbon monoxide in pig house 2. When a fire is built in the enclosed pig house 2 in winter, if the fuel burns incompletely, a large amount of carbon monoxide will be produced. Carbon monoxide is toxic to the blood and nervous system. It enters the blood circulation through the alveoli and combines with hemoglobin to form a relatively stable carboxyhemoglobin. This hemoglobin is not easy to dissociate. It not only reduces the oxygen-carrying function of blood cells, but also inhibits and slows the dissociation of oxygenated hemoglobin and oxygen. Release, causing acute hypoxia in the body, dysfunction of blood vessels and nerve cells, respiratory, circulatory, and nervous system diseases. The dissociation of carboxyhemoglobin is 3,600 times slower than oxyhemoglobin, so there is a long-lasting poisoning after poisoning. Function, when the concentration of carbon monoxide is 0.05%, acute poisoning can be caused in a short time, and the concentration of carbon monoxide in pig house 2 should be less than 0.0025%;

The main source of carbon dioxide is the breathing of pigs in the house. A fat pig weighing 100 kg can exhale 43 liters of carbon dioxide per hour. Therefore, the carbon dioxide content in pig house 2 is often many times higher than that in the atmosphere. The carbon dioxide itself is non-toxic and its main harm It causes hypoxia and causes chronic poisoning. Pigs who are in an oxygen-deficient environment for a long time will be sluggish, lose appetite, decrease physical fitness, decrease productivity, weaken resistance to diseases, and are particularly susceptible to infections such as tuberculosis. In pig house 2. The volume concentration of carbon dioxide should not exceed 0.15%. Although carbon dioxide itself does not cause pig poisoning, the hygienic significance of carbon dioxide concentration is that it can indicate the degree of pollution of the air in pig house 2 and how much other harmful gases may exist in the air in the house. Therefore, the carbon dioxide concentration can be used as an indirect indicator of the sanitary assessment of pig house 2;

When the concentration of any of the above harmful gases exceeds the standard, the terminal controller can open the electric doors and windows for ventilation, and cooperate with the central air conditioner to ventilate the pig house 2 to reduce the concentration of harmful gases.

S3. Live pig status detection: Set electronic coordinates for each pig pen 21 in pig house 2, and store the electronic coordinates in the storage device of the terminal controller and the UAV controller 12, and monitor the UAV 1 according to each The electronic coordinates of the pigpen 21 plan the flight route, and the terminal controller sends instructions to the surveillance drone 1 every 30 minutes to make the surveillance drone 1 fly along the planned flight route, and hover at each electronic coordinate for 3min-5min, and shoot The information of the pigs in each pigpen 21 is detected by the infrared body temperature detector 15 at the same time, and the measured data is wirelessly transmitted to the terminal controller and the mobile terminal;

Specifically, the value of the electronic coordinates is the coordinate value of the center of each pigpen 21 in the pig house 2. When the drone stays at the center of the pigpen 21, the pigpen 21 can be taken more clearly and completely. .

S4, Pigpen 21 environmental pollution alarm: The terminal controller analyzes the information of the pigpen 21 captured by the surveillance drone 1 in S3, and judges the pollution level in the pigpen 21 through image recognition technology. If it exceeds a predetermined value, it will immediately report The mobile terminal sends alarm information;

Specifically, the pollution of pigpen 21 is mainly caused by pig excrement. These excrement can breed various bacteria and easily make pigs sick. Therefore, the drone can transmit the picture to the On the mobile terminal, the breeder can watch the sanitation status of the pig pen 21 online, make cleaning arrangements, and can also judge the health of the pigs by observing the excrement of the pigs;

S5, Live pig health status alarm: The terminal controller analyzes the body surface conditions of the pigs taken by the surveillance drone 1 in S3 and the infrared body temperature detector 15 to analyze the body temperature conditions of the pigs. The body surface conditions mainly include the eyes and mouth of the pigs. The nose, skin, etc. are compared and identified with pictures. If pathological changes are found, determine the possible diseases involved and immediately send the information to the mobile terminal for alarm;

Specifically, there are tear marks or excrement on the eyes of pigs, and the diseases that may be involved include influenza and swine fever;

The normal body temperature of pigs is 38℃～39.5℃ (rectal temperature), and the body temperature of pigs of different ages is slightly different. For example, the body temperature of newly born pigs is 39.0℃; suckling piglets 39.3°C; middle pig 39.0°C; fat pig 38.8°C; pregnant sow 38.7°C; boar 38.4°C.
