Thermal comfort monitoring in aviaries by a real-time data acquisition system

ABSTRACT Thermal comfort inside broiler husbandry facilities is essential in obtaining good results in the production activity. Assessment of adequate thermodynamic conditions requires measurement and control, usually implying costs and specialized maintenance. The objective of this research was to monitor the temperature, relative humidity and air speed distributions by a developed low-cost, open-source and easy-to-use measurement system, using Arduino (hardware) and Scilab (software) for real-time data acquisition. Sensors were installed in a real facility (Cianorte, PR), with measurements for internal ambient (20 sensors for temperature/relative humidity, and two sensors for differential pressure, respectively 0.5 and 1.5 m high) and external ambient (pressure and wind speed, 1.5 m high). Data acquisition system has enabled communication with sensors which are easily read by the computer and stored in a data file. The developed data acquisition system proved to be efficient when applied in a commercial broiler husbandry facility, enabling real-time monitoring for thermal comfort parameters.

摘要：肉鸡养殖舍内的热舒适环境对保障养殖生产的良好成效至关重要。对适宜热力学环境的评估需要开展测量与调控，而这通常会产生相关成本并需要专业运维。本研究旨在通过一套自研的低成本、开源且易用的测量系统，结合Arduino（硬件）与Scilab（软件）开展实时数据采集，以监测舍内温度、相对湿度与空气流速的分布情况。传感器部署于实际养殖场（巴西巴拉那州锡安诺特市），分别针对舍内与舍外环境布设设备：舍内布设20套温湿度传感器，以及2套分别安装于0.5m和1.5m高度的差压传感器；舍外布设1套安装于1.5m高度的气压与风速传感器。该数据采集系统可实现与传感器的通信，采集的数据可通过计算机便捷读取并存储至数据文件中。经商用肉鸡养殖场实地应用验证，本自研数据采集系统表现出良好的运行效能，可实现热舒适相关参数的实时监测。
