Description

TECHNICAL FIELD

[0001] The utility model relates to the field of agricultural information technology, concretely relates to a multi -target beef cattle respiratory heart rate monitoring device. BACKGROUND

[0002] Agriculture is an important part of China's national economy, and has always occupied an absolutely stable foundation position. With the rapid development of modern animal husbandry, real-time monitoring of beef cattle health status becomes increasingly important. Timely and accurate monitoring of beef cattle vital signs, such as respiration and heart rate, is of great significance for early detection of diseases, assessment of beef cattle health status, and improvement of breeding efficiency. Traditional beef cattle vital sign monitoring methods mainly rely on contact sensors, such as electrocardiogram (ECG) devices or pulse oximeters. Although these methods can provide accurate data, they require beef cattle to wear or approach the device for a long time, limiting their freedom of movement, and are cumbersome and costly to implement in large-scale breeding environments.

[0003] In recent years, non-contact monitoring technology has attracted attention due to its ease of operation, minimal disturbance to beef cattle, and other advantages. Among them, monitoring devices based on machine vision estimate vital signs by analyzing video images of beef cattle, but this method is susceptible to changes in environmental lighting and visual obstructions, making it difficult to accurately monitor individuals in densely populated or frequently active environments, and the accuracy of monitoring the tiny heartbeat signal is low. On the other hand, radar-based monitoring devices use electromagnetic wave reflection principles to detect the tiny movements of beef cattle, thereby extracting respiration and heart rate information, and have good environmental adaptability and penetration ability. However, traditional radar devices have insufficient resolution and difficulty in signal separation when processing multi-target signals, especially when there are many beef cattle close to each other, it is difficult to accurately distinguish and monitor the vital signs of each individual, and the use of single-target measurement methods is inefficient, therefore we propose a multi-target beef cattle respiratory heart rate monitoring device.
