In modern large-scale, intensive pig farming, environmental management is directly related to pig health, growth rate, feed conversion rate, and overall production efficiency. Traditional pig house environmental control relies on manual experience to set temperature control parameters. This not only results in delayed response but also struggles to adapt to seasonal changes, pig age differences, and external climate fluctuations. To address this challenge, based on Yuhong's patented technology—the automatic setting system for environmental indicators in livestock and poultry house environmental control—the pig house environment management system has achieved a leap from "manual intervention" to "intelligent self-control." It automatically sets target temperatures based on environmental changes and autonomously optimizes operating plans, comprehensively improving the stability and intelligence of the pig house environment.1. Intelligent Temperature Control: Automatic Target Setting Based on Multiple FactorsThe core breakthrough of this system lies in its patented automatic setting function for environmental indicators. The system's built-in intelligent algorithm automatically calculates and sets the optimal target temperature based on real-time data from the pig house's internal and external environments. The system no longer relies on fixed setpoints. Instead, it dynamically generates an optimal daily temperature curve based on the pig's biological characteristics, such as age, weight, and rearing stage, and references standard growth models. For example, since piglets require high temperatures for insulation during the nursing stage, the system automatically sets the temperature to 28–32°C. In the later stages of fattening, the temperature is gradually lowered to 18–22°C, ensuring the pigs remain in the thermoneutral zone and reducing heat and cold stress. More importantly, the system can detect sudden changes in external climate (such as cold snaps or high temperatures) and proactively adjust ventilation and heating strategies, achieving "predictive control" to prevent the impact of drastic temperature fluctuations on the pig herd.2. Multi-factor Collaborative Optimization: Odor Gradient Treatment and Variable Frequency ControlTemperature is not an isolated indicator. Another patented invention of the Yuhong system, the In-House Odor Gradient Treatment technology, achieves coordinated control of multiple environmental factors, including temperature, humidity, and ammonia concentration. The system uses temperature as the primary control factor, while using humidity and ammonia concentration as correction factors to dynamically adjust the operating frequency of equipment such as fans, wet curtains, and heaters. When ammonia concentrations rise, the system doesn't simply turn on the fans at full power. Instead, it uses variable frequency technology to gradually increase ventilation based on current temperature and humidity conditions. This effectively reduces harmful gases while preventing sudden drops in barn temperature caused by over-ventilation. This "gradient treatment" approach significantly improves pig house environmental stability and pig comfort, reduces respiratory illnesses, and promotes healthy growth.3. Autonomous Learning and Optimization: Continuously Improving Control AccuracyThe system boasts autonomous optimization capabilities, recording historical environmental data and equipment operating status, analyzing the environmental responses under different control strategies, and gradually optimizing the control model. For example, after several consecutive days of rainy weather, the system learns the pattern of declining evaporation efficiency of wet curtains in high-humidity environments and automatically adjusts its start-stop strategy to avoid excessive water spraying that could dampen bedding. This "smarter-with-use" feature enables the system to continuously improve control accuracy, reduce energy consumption, and enhance management efficiency over time.4. High-Reliability Design: Ensuring Stable System OperationTo ensure reliable operation in complex farm environments, the system adopts a modular design, with each functional unit operating independently. Failure of a single module will not cause the entire system to fail. Equipped with multiple lightning protection measures and a backup control system, if the main system trips but the utility power is normal, the backup system automatically activates, ensuring the continuous operation of critical equipment (such as fans) and preventing the risk of suffocation caused by power outages.5. IoT and Human-Machine Collaboration: Remote Management and Flexible InterventionThrough IoT functionality, managers can remotely view real-time environmental parameters, equipment status, historical curves, and conduct remote control. The system also features 33 alarm functions and self-diagnostic capabilities. When a fault occurs, it accurately describes the fault location in text form (e.g., "South fan drive module abnormality"), facilitating rapid troubleshooting by field personnel. It also retains dual manual/automatic modes, allowing users to manually intervene in special circumstances, achieving a balance of intelligence and operational flexibility.Utilizing Yuhong's patented technology, the pig house environment management system has achieved a comprehensive upgrade from "passive response" to "active prediction," and from "single temperature control" to "multi-factor collaborative optimization." It is not only an environmental control device, but also the "brain" of smart farming. By automatically setting temperature targets and independently optimizing operating strategies, it creates a stable, comfortable and healthy growth environment for pigs, helping the modern pig farming industry develop in an efficient, intelligent and sustainable direction.
