Abstract
Description
Technical Field
[0001] This invention belongs to the field of environmental monitoring technology, specifically relating to a method and system for monitoring the livestock production environment based on the Internet of Things. Background Technology
[0002] In livestock production environment monitoring, deployed sensors need to collect key environmental parameters such as temperature, humidity, light intensity, and harmful gas concentrations in real time. These sensors are typically installed in different areas of the farm to ensure the comprehensiveness and representativeness of the data. However, due to the complex environment of farms, sensors face several technical challenges in actual operation. First, sensors need to operate stably and continuously under conditions of high humidity, high dust, and extreme temperatures, placing extremely high demands on their durability and accuracy. Second, the data collected by the sensors needs to be transmitted to the management cloud platform via a wireless network, but within the farm, wireless signals may be interfered with by buildings, equipment, and animal activities, leading to unstable or delayed data transmission. Furthermore, sensors may experience insufficient battery power or equipment aging after prolonged operation, affecting the continuity and reliability of the data. Simultaneously, environmental parameters may vary significantly between different areas of the farm; for example, poorly ventilated areas may accumulate harmful gases, while well-lit areas may experience excessively high temperatures. This necessitates sensors capable of differentiated monitoring for different areas, but existing systems often struggle to achieve this level of refined management. Finally, the management cloud platform needs to process and analyze massive amounts of sensor data in real time. However, given the sheer volume and diverse sources of this data, efficiently integrating and processing it while avoiding redundancy and errors remains a critical technical challenge. These issues collectively constitute the core challenges in livestock production environment monitoring, requiring gradual solutions through technological and system optimization. Summary of the Invention

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0048] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0049] Example 1
[0050] like Figure 1 As shown, this invention provides a method for monitoring the livestock production environment based on the Internet of Things (IoT), the method comprising:
[0051] Sensor modules were deployed in different areas of the farm to collect data on temperature, humidity, light intensity, and concentration of harmful gases, and the data was preprocessed.
[0052] Edge computing technology is used to perform preliminary processing on the pre-processed data, extract key features, and then transmit the data to the cloud platform.
[0053] Establish a regionally differentiated monitoring model in the cloud platform to monitor key characteristic data in real time. If abnormal fluctuations in temperature, humidity or concentration of harmful gases are detected, trigger the early warning mechanism and notify the management personnel to handle the situation in a timely manner.
[0054] Deploy data fusion algorithms in the cloud platform to integrate sensor data from multiple regions and generate a global environmental parameter distribution map.
[0055] In this embodiment, an adaptive filtering algorithm is integrated into the sensor module to preprocess data in high-humidity and high-dust environments, remove noise interference, and improve data accuracy, including:
[0056] The sensor module is deployed in the high-humidity and high-dust area of the farm to collect temperature, humidity, light and gas data;
[0057] An adaptive filtering algorithm is used to preprocess the original data to remove noise interference, resulting in a filtered dataset.
[0058] Based on a preset threshold, determine whether the filtered temperature value exceeds the threshold.
[0059] If the temperature value exceeds the threshold, a temperature anomaly warning is triggered, and the filtered humidity value and gas value are obtained for correlation analysis.
[0060] If neither the humidity nor the gas value exceeds the preset threshold, only the temperature anomaly information will be recorded and the data set will be updated.
[0061] If the humidity or gas value exceeds the preset threshold, a comprehensive early warning will be triggered, and a comprehensive anomaly report will be generated.
[0062] The K-means clustering algorithm was used to classify the comprehensive anomaly reports, determine the anomaly types and frequencies, and generate environmental monitoring results for the aquaculture farm.
[0063] In this embodiment, the method for deploying sensor modules in different areas of the farm includes:
[0064] The preprocessed data is transmitted through low-power wide-area network technology. Specifically, relay nodes are deployed in the farm, and the location and number of nodes are planned in a reasonable manner.
[0065] Establish a data caching mechanism in the cloud platform. If a data packet is detected to be lost or delayed, the missing data will be automatically resent from the cache.
[0066] Based on cached data, multiple types of sensors are deployed to address environmental differences in different regions.
[0067] Specifically, the arrangement of relay nodes within the farm, and the rational planning of node locations and numbers, include:
[0068] Based on the location and number of nodes, the signal coverage and strength are calculated to determine if there are any signal blind spots. If blind spots exist, the node locations and numbers are adjusted. Signal coverage and strength data are acquired, and the relay node layout is optimized in conjunction with the distribution of buildings and equipment to reduce signal interference. Filtered data is transmitted through the optimized relay node layout, and signal transmission quality is monitored to determine if there is any data loss or delay. If data loss or delay is detected, the relay node layout is readjusted, and signal transmission quality is monitored again until the preset transmission standards are met. Clustering algorithms are used to classify the transmission quality data, determine the distribution patterns of signal coverage and interference, and generate signal coverage and interference distribution maps. Based on the signal coverage and interference distribution maps, the relay node layout is updated to continuously optimize data transmission efficiency and signal coverage.
[0069] Specifically, based on the data packet content in the buffer, multiple types of sensors are deployed in the transmission chain to acquire environmental data for each area. For the acquired environmental data, detection points monitor the integrity and timeliness of the data packets, recording the amount of data loss and latency. If a detection point detects data packet loss or latency, a retransmitter extracts the missing values from the buffer and resends them to the transmission chain. Based on the retransmitter's operational data, the environmental monitoring status of each area is updated, clarifying regionally differentiated environmental standards. Clustering algorithms are used to classify the amount of data loss and latency, obtaining the data anomaly distribution patterns for different areas. Based on these data anomaly distribution patterns, the buffer's storage strategy is adjusted, and the regionally differentiated monitoring model is optimized. Through the optimized monitoring model, the sensor deployment strategy is reconfigured to achieve refined environmental management.
[0070] In this embodiment, as Figure 2 As shown, edge computing technology is used to perform preliminary processing on the preprocessed data and extract key features. The methods include: extracting key features by constructing an edge computing network architecture framework, which includes: service layer, platform layer, transmission layer, edge layer, and perception layer.
