Design and implementation of automatic monitoring system for layers production parameters

In order to identify and avoid risks during the breeding process of laying hens, it is necessary to acquire real-time and continuous data of laying hens' physiology and production parameters. At present, data acquisition and processing is mainly dependent on the manual mode, which is a very costly and time consuming process. Meanwhile, the data obtained from human observation involves strong subjectivity, which could be disadvantageous for carrying out accurate, stable, and continuous recording. This paper discusses the factors influencing of the polling cycle, and provides a formula to determine its appropriate value. The paper also elaborates on the communication process between server and sensor, and describes the working principles of the sensors for food intake, water intake, excretion volume, egg production time, egg quantity, and egg quality respectively The results indicated that this system operates stably; the average relative error of food intake, water intake, excretion volume, and egg quality is
