Abstract: The present invention discloses an intelligent, automated, and energy-autonomous bird health monitoring system that integrates Internet of Things (IoT), artificial intelligence (AI), and renewable energy technologies. The system comprises two independent microcontroller-based edge devices: a Smart Sensory Numeric Data Collector Device (SSNDCD) and an Edge Vision Data Collector Device (EVDCD). The SSNDCD collects real-time physiological and environmental data using multiple sensors including humidity, gas, temperature, vibration, and weight sensors, along with GPS and timestamping modules. The EVDCD captures visual and auditory data using an HD camera and microphone, and performs lightweight edge AI processing for preliminary image and sound analysis. Both devices transmit data wirelessly to a centralized cloud server, where multimodal data is preprocessed and analyzed using a pre-trained AI model to classify bird health status into healthy, stressed, sick, or critical. Upon detecting abnormalities, the system generates alerts with health condition, location, time, and recommended actions, sent directly to caretakers or farm managers. Powered by solar energy with rechargeable batteries, the system operates continuously and independently, making it suitable for deployment in remote or power-limited environments such as poultry farms, aviaries, breeding centers, and wildlife sanctuaries. The system enables real-time monitoring, early disease detection, reduced mortality, and improved animal welfare through automated and intelligent health assessment.

Specification

Description:FIELD OF THE INVENTION
This invention relates to AI-Powered Sensor-Vision Platform for Remote and Real-Time Bird Health Prediction with GPS-Linked Alerts.
BACKGROUND OF THE INVENTION
The methods of bird health monitoring in aviaries and farms used traditionally are largely manual as well as time-consuming, labour-intensive and human oversight prone. Early signs of illness in birds like changes in posture, vocalization or behaviour often go undetected which results in increased morality rates and delayed diagnosis. The existing systems are not capable of providing automated, real-time and intelligent health assessments. Moreover, there is no system present with combine multimodal sensing like a system which can work on environmental, visual and physiological data at a single time with AI-driven analysis for accurate prediction of bird health conditions. In many of the cases energy is a hurdle in continuous operation of electronic monitoring systems in remote or rural areas. Therefore, there comes a need for a AI-based health monitoring solution which is self-sustained and solar powered that can automatically detect abnormalities and provide timely alerts for early intervention.
Recently, bird farming and poultry industries have grown substantially to meet the increasing global demand for eggs and meet. However, the welfare and health of birds is a critical concern as the diseases can spread in a fast manner in flocks and lead to reduced productivity, significant losses and ethical issues which are related to animal welfare. The bird health monitoring methods used traditionally primarily relies upon manual inspection by veterinarians or farm staff who observes physical symptoms, behavioural changes and morality patterns. These practices are labour-intensive as well as time consuming and also lacks off objectivity and consistency. Most importantly the early signs of illness such as altered vocalization, reduced activity or minor changes in feeding behaviour often go unnoticed which allows the diseases to progress undetected.
Furthermore, existing digital solutions in the market are either overly simplistic or require expensive infrastructure that is not sustainable or scalable, especially in resource-constrained and rural environments. Most of the available systems do not integrate the real-time physiological sensing with environmental and behavioural monitoring nor do they use advanced AI algorithms for providing predictive analytics. The lack of multimodal data fusion leads to poor diagnostic accuracy and delays in timely intervention. In addition, this system depends upon frequent manual maintenance or constant power sources making them unsuitable for continuous deployment in field conditions.
Energy is another major limitation. Farms which are located at remote areas with unstable electricity supply which makes it difficult to run continuous monitoring systems using the conventional power sources. Existing sensor-based systems are not designed for low-power operations and hence can’t function autonomously for extended periods without power replacement or manual recharging. Moreover, many of the systems do not support geolocation capabilities which are essential for tracking and managing bird populations across distributed or large farms.
Due to these challenges, there is a necessary need of an autonomous and comprehensive bird health monitoring system which can identify signs of disease early, operate in real-time and function reliable in field environments. This system should be capable of collecting the multimodal data such as physiological readings and numerical environmental readings as well as audio and visual inputs using dedicated edge devices. It should leverage artificial intelligence for deliver timely alerts and health prediction to caretakers including precise GPS location data. Additionally, the system must be self-sufficient in terms of energy by integrating battery with solar power which enables 24/7 operation without any external power dependency. Addressing these gaps would significantly enhance early detection of disease, improve welfare of bird and support sustainable poultry management practices.
US20230389525A1 The present disclosure relates to a system for measuring changes in the vital signs of poultry and a method for predicting whether poultry is infected with pathogens using the same. The present disclosure can be helpfully used to determine an overall health condition including the outbreak of various poultry diseases by measuring quantitative changes in vital signs of poultry in real time. In particular, the present disclosure provides reliable real-time information about changes in vital signs through comparison of body temperature and noise measurement values of poultry for each time period reflecting circadian changes of the poultry, rather than simple comparison of the body temperature and noise measurement values with simple reference values, and thus can be used for early diagnosis of highly infectious pathogens such as avian influenza virus and early isolation of confirmed cases, and ultimately for effective prevention of the spread of diseases.
RESEARCH GAP: Unlike the referenced system which focuses on vital signs (temperature and noise) and circadian analysis for pathogen prediction, the proposed system integrates multi-sensor IoT and edge-AI vision modules to monitor posture, behavior, GPS, and environmental data for a broader and more intelligent real-time poultry health assessment.
CN116934088A The invention discloses an intelligent pigeon breeding management method and system based on an analysis model, and relates to the technical field of management systems, wherein the pigeon breeding method comprises the following steps: the pigeon house environment analysis result is combined with the disease risk early warning mechanism by periodically acquiring characteristic data related to pigeon house environment, comprehensively analyzing the characteristic data, analyzing whether the pigeon house environment supports pigeon feeding, formulating a pigeon house optimization scheme according to the analysis result, periodically acquiring the characteristic data related to pigeon growth, establishing the disease risk early warning mechanism through the characteristic data, carrying out disease risk early warning on the pigeon through the disease risk early warning mechanism and generating a corresponding management strategy. The pigeon breeding system and the pigeon breeding method can evaluate the pigeon cage environment and early warn the disease risk of the pigeons, so that the breeding management is effectively optimized, the overall growth trend analysis is carried out on the pigeons bred in the same batch, the breeding effect is effectively evaluated, and the effectiveness of the breeding strategy is determined.
RESEARCH GAP: While the referenced system focuses on environmental analysis and disease risk early warning for pigeons using periodic data collection, the proposed system combines real-time multi-sensor data, edge AI-based posture and vocal analysis, and GPS tracking to enable continuous, individualized health monitoring and predictive diagnostics in poultry.
None of the prior art indicate above either alone or in combination with one another disclose what the present invention has disclosed. This invention relates to AI-Powered Sensor-Vision Platform for Remote and Real-Time Bird Health Prediction with GPS-Linked Alerts.

ADVANTAGES OF THE INVENTION:
The key advantages that make it a valuable tool for bird health prediction are:
• The proposed system enables automated and continuous monitoring of bird health without requiring any manual observation. By capturing data at regular intervals from both audio/visual analysis and sensor inputs the system detects abnormal patterns in real time. This allows for the early identification of stress or diseases indicators which helps the caretakers or farm managers to respond before conditions get worsen, thereby reduces morality rates and improves flock health outcomes.
• Unlike the old traditional single-mode monitoring this proposed system utilizes multimodal data collections from two devices i.e. EVDCD and SSNDCD. The SSNDCD gathers environmental as well as numerical data such as temperature, humidity, body weight, ammonia levels and GPS location. The EVDCD captures audio and images for analysing distress sounds and behavioural cues. This fusion of environmental, physical and behavioural data results in a more holistic and accurate understanding of each bird’s health condition.
• This whole system works upon rechargeable batteries which is powered by solar panels which allows the system to work 24/7 in remote or rural location whether there is poor or lack of grid electricity. This makes the system energy efficient as well as sustainable.
• At the core of the system there present an artificial intelligence model which is pretrained by the existing data. This model uses machine learning algorithms for recognizing the patterns associated with sick, stressed, healthy or critically ill birds. It evaluates real-time as well as historical data to predict the likelihood of disease progression, enabling preventive action. This reduces the need for constant human oversights and improves decision-making through data-driven insights.
