A Data Collection Collar for Vital Signs of Cows on the Grassland Based on LoRa

Abstract

In recent years, animal husbandry in China has developed rapidly. However, due to poor network environment in pastoral areas, IoT technology is difficult to apply. Due to the lack of effective supervision, livestock suffer from varying degrees of health problems. This has seriously affected the development of animal husbandry. The emergence of lowpower, long-distance Internet of Things technologies, represented by Lora, has made it possible to establish a realtime monitoring system for the behavior of livestock. This system includes nodes, gateways, and servers, and is based on LoRaWAN. These nodes take the SX1278 as the core and integrate the STM32L151 low-power controller, GPS, and accelerometer. The system is tested and analyzed. The experimental results show that the scheme has the characteristics of long communication distance, low power consumption, convenient networking, and good real-time performance. It has a wide range of application prospects.
