Description

Technical Field

[0001] This invention relates to the field of intelligent management technology for livestock and poultry farming, specifically to a production status assessment system and method for livestock and poultry farms. Background Technology

[0002] With the rapid development of large-scale and intensive livestock and poultry farming, real-time and accurate assessment of the production status of farms has become a key link in improving farming efficiency, ensuring animal health, reducing disease risks, and achieving green and efficient production.

[0003] The existing technology has the following defects or problems: 1. Traditional farming relies heavily on manual inspections, single-point environmental sensors, or simple monitoring. Environmental data (temperature, humidity, ammonia, etc.), individual behavioral and health data (feeding, drinking, weight, thermal imaging), and production management data (feeding amount, veterinary drug use) are fragmented, misaligned in time and space, and inconsistent in format, making it difficult to accurately judge the overall condition. 2. Existing systems mostly use fixed indicators or human experience to make judgments. The environmental sensitivity of different livestock (pigs / cattle / poultry), different growth stages (piglets / fattening / peak egg production), and different seasons varies greatly, which can lead to misjudgments or redundant indicators. 3. Traditional methods rely on veterinary inspections or simple thresholds, which make it difficult to capture early trend changes (such as abnormal HRI slopes in 3–7 days), leading to the spread of diseases, feed waste, or decreased production efficiency. 4. Existing monitoring systems mostly consist of simple reports or lack push notifications, making it difficult for managers to obtain key information in a timely manner, especially at night or in remote areas.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

The feeding curve execution and deviation alarm subunit is used to preset the feeding curve according to the animal's age and weight stage, and to issue an alarm when the actual feed intake deviates from the target curve by more than a set threshold. The animal health and drug management unit is used to update inventory levels in real time, and can also correspond veterinary drug / vaccine usage records with animal electronic ear tags / batch numbers to form a traceability chain.

[0009] In some embodiments, the ecological state indicator system construction module specifically consists of the following sub-modules: The sub-module for selecting adaptation indicators of livestock and poultry species and growth stages has a built-in classification library of livestock and poultry species, which is used to pre-store characteristic parameters of different livestock and poultry such as pigs, cattle and poultry, including manure production coefficient, feed conversion rate benchmark and environmental sensitivity threshold. The growth stage division unit can automatically match the corresponding set of evaluation indicators based on the age, weight stage and physiological period of livestock and poultry.

[0010] In some embodiments, the ecological status indicator system construction module has a built-in dynamic indicator screening logic, which is used to automatically select and activate 10-25 core evaluation indicators from a preset indicator pool based on the livestock and poultry species and current growth stage, avoiding indicator redundancy. The specific algorithm flow is as follows: 1) Obtain the current livestock and poultry species code and current growth stage label; 2) Load the preset livestock-stage-indicator association knowledge base, which includes the recommended indicator set, the required indicator set, the alternative indicator set and the indicator ecological sensitivity coefficient (range 0-1) for each type of livestock and poultry × each growth stage. 3) Complete the first layer of filtering, which specifically involves mandatory matching from category to stage and activation of required indicators, including: The essential core indicator set for the livestock and poultry species and growth stage is directly extracted from the knowledge base.

All candidate metrics are sorted in descending order of Priority Score, and the top N metrics are initially selected, with a target activation number × 1.5-2.0. 5) Complete the third layer of filtering, which specifically involves removing redundant related information, including: For the initially selected index set in the second layer, calculate its pairwise Pearson correlation coefficient matrix between the standards; Hierarchical clustering is used to retain only the item with the highest Priority Score in each highly correlated index cluster, and the rest are marked as redundant and to be removed. 6) Complete the fourth layer of filtering, which specifically involves quantity constraints and coverage verification, including: From the list of redundancies removed, continue to add indicators in descending order of Priority Score until the number of activated indicators reaches the lower limit of the target range. The formula for calculating the multi-dimensional coverage of the current set of activated indicators on the ecological state is as follows: Coverage = (Number of covered dimensions / Total number of dimensions) × 100% + Weighted sum of indicator saturation for each dimension; If the coverage is less than 85% and the number of fecal waste resource utilization indicators is less than 2, the highest priority indicators will be added from the candidate pool until the minimum coverage requirement is met. The final number will be controlled between 10 and 25. If the upper limit is exceeded, the indicators will continue to be removed from the priority score from low to high until the upper limit is reached.

Hide dimensions in the model; The above algorithm is repeated 4-8 times, with each layer including multi-head attention and a feedforward network; The core formula for multi-head self-attention is: ; Its bullish version formula is: ; ; Where h is the number of heads, and d_k = d_model / h (dimension of each head), this part allows the intelligent assessment model to simultaneously focus on cross-time non-local strong correlations such as ammonia exceeding the standard 3 days ago, yesterday's temperature difference, and today's decrease in water intake; The formula for the pre-network is as follows: .

[0012] In some embodiments, the early warning and push module is specifically composed of the following modules: The real-time data receiving and buffering layer can predict results in real time, with the time interval controlled at 5-60 minutes, and can also maintain the sliding time window buffer of each breeding unit.

This system constructs a complete production status assessment system that is data-driven, dynamically intelligent, and closed-loop traceable. It has significant technological advancement, economic practicality, and promotion and application value. It enables multi-dimensional, real-time, and quantitative assessment of the production status of farms, making up for the shortcomings of traditional manual inspections.
