A method and system for controlling an ear tag reading strategy based on cascaded nakagami
By adopting a cascaded Nakagami-based animal ear tag reading strategy control method, the moment estimation method is used to determine the breeding scenario and trigger three parallel interventions. This solves the problem of ear tag reading failure caused by wireless signal fading in high-density breeding environments, improves the reading success rate and system efficiency, and provides intelligent perception of abnormal events.

AI Technical Summary
Existing technologies cannot effectively address the failure to read animal ear tags due to wireless signal fading in high-density farming scenarios. Especially in high-density farming environments, the channel environment is extremely deteriorated. Existing RFID readers cause frame length to be lengthened due to misjudgment of collisions, which reduces the success rate of ear tag reading.
An animal ear tag reading strategy control method based on cascaded Nakagami is adopted. By acquiring the continuous incoherent radio frequency envelope sequence of animal ear tags, the Nakagami shape parameters are calculated using the moment estimation method to determine the physical scene of the farm. In the super Rayleigh cascaded scene, three parallel interventions are triggered: collision avoidance adaptive, modulation coding enhancement and early warning signal generation.
It significantly improves the success rate of animal ear tag reading in high-density breeding environments, avoids blind retreat, improves system efficiency, and enables intelligent perception and management of abnormal events.
