UtilizingInternet of Things technology, focusing on facility basedlivestock and poultry breedingproduction and management processes,intelligent sensorsare used to collect environmental data (carbon dioxide, ammonia, hydrogen sulfide,temperature and humidity, etc.) online from the breeding farm, while integrating or retrofitting existing breeding environment control equipment. Real time monitoring and alarm information can be pushed to managers through information terminals such as mobile phones and computers.
Ensure that the environment in the breeding farm is suitable for animal growth, achieve refined management, and enable resource integration, data sharing, and business collaboration inanimal husbandry, which can help transform and upgrade the modern animal husbandry industry.
IoT intelligent breedingcontrol system mainly consists of two core parts:environmental data collectionandintelligent control. Through the close cooperation of the two parts,IoTThe role of technology in animal husbandry is to ensure that the breeding environment is suitable for the growth of livestock and poultry, achieve refined management, create conditions for high yield, ecology, and safety in breeding, and achieve the goals of healthy breeding, energy conservation, and consumption reduction.
System composition and functions
1. Intelligent environment monitoring
Through sensors, audio, video, and remote transmission technology, online collection of environmental information (carbon dioxide, ammonia, hydrogen sulfide, air temperature and humidity, noise, dust, etc.) and the growth behavior of livestock and poultry (feeding, water intake, excretion, etc.) is carried out in the breeding farm. Real time monitoring of the breeding environment information in the facility is carried out to timely warn of abnormal situations and reduce losses.
temperature and humidity
By comparing indoor and outdoor temperature sensors, in hot summer, when the temperature inside the building is higher than the outside temperature, the fan can be started for air exchange to reduce the temperature inside the building. Similarly, when the humidity inside the building is high and the outside humidity is high, ventilation and dehumidification can also be carried out; In the cold winter, especially in the north, it is necessary to carry out insulation treatment for livestock and poultry breeding, and provide heating (such as solar energy, electric stoves, boiler heating) when appropriate.
Gas monitoring
The air in livestock and poultry farms contains ammonia, hydrogen sulfide, carbon dioxide and other gases. If the concentration of these gases is too high and the action time is long, the livestock and poultry will become worse, the resistance will be reduced, and the incidence rate will be higher. Therefore, ventilation and air exchange equipment such as fans should be installed to timely discharge polluted air and continuously introduce fresh air. Deodorization equipment should be installed to regularly scrape and deodorize feces. Real time monitoring of indoor gas concentrations through gas sensors such as ammonia, hydrogen sulfide, and carbon dioxide in livestock and poultry breeding. When the concentration reaches a certain level, ventilation and deodorization should be carried out to protect the air circulation and freshness in the house. Ventilation and air exchange should also consider the impact on the temperature and humidity inside the building. In winter, choose ventilation and air exchange when the temperature is high, and in summer, choose cool nights or mornings for ventilation and air exchange.
illumination
Adequate lighting time is an important factor in ensuring the health, rapid growth, and efficient milk production of cattle. For situations where the light in livestock and poultry farming is dim or the winter sunshine is insufficient on cloudy days, auxiliary lighting should be appropriately increased to compensate for the lack of light intensity caused by weather and seasonal factors. The illumination automatic adjustment function in the automatic control system can achieve free adjustment of the illumination inside livestock and poultry breeding.
Stress
Due to poor ventilation and other reasons at times, there may be differences in pressure between the internal and external environment of livestock and poultry farming, which is not conducive to the circulation of gases inside and outside. This is also a factor contributing to the high concentration of harmful gases in the building. When there is a pressure difference between the inside and outside, relevant equipment should be activated for ventilation and air exchange to ensure air circulation.
2. Intelligent water supply
Monitoring of on-site water pumps
The staff monitors the working status, working voltage, and current data of the water pump in real time through the monitoring platform, and remotely controls the start and stop of the water pump manually;
3. Energy consumption monitoring
Water consumption monitoring
By using flow meters and remote transmission terminals such as 4G/network, the water consumption of individual pig houses/cow houses/chicken houses and the entire breeding farm can be statistically analyzed, forming data curves and reports
4. Unified regulation
Realize centralized, remote, and coordinated control of the environment (including illumination, temperature, humidity, etc.) inside the breeding house. The control layer mainly includes temperature control, humidity control, ventilation control, lighting control, and timed feeding and water feeding.
