摘　　要：为了实现养殖过程精细投喂、并实时在线监测蛋鸡行为,在基于影响蛋鸡生长的主要环境参数基础上,提出了基于物联网的蛋鸡环境监控系统总体设计方案;并针对蛋鸡环境特点,选择了适当的传感器和传感器布置位置。然后采用RS-485总线技术,搭建了从信息采集模块、显示模块、通信接口和控制接口的监控终端。对于在鸡舍不利于布线的地方,其环境信息采集采用了无线传感网络。在服务器端则采用基于MySQL数据库的Web鸡舍环境监控系统,在网络接口上通过ENC28J60以太网控制器实现。为了更准确有效地获取所感知的数据,在无线传感网中采用了基于ACK方式的丢失重传检测,实验结果表明该方法能够有效地提高数据的可靠性。In order to achieve the feeding process of precision feeding and real-time monitoring of laying hens' behavior, the designed scheme of the environment monitoring system based on Internet of things was put forward based on the main environmental parameters that affect the growth of laying hens. According to the hens' environment characteristics, the appropriate sensor and sensor placement were chosen. Then the RS-485 bus technology was used to set up monitoring terminal from the information acquisition module, display module, communication interface and control interface. For the place is not conducive to setting up the wiring in the chicken coop, the wireless sensor networks were used for getting its environmental information. On the server side,the web chicken coop environmental monitoring system was built based on the MySQL database. For the network communication interface the ENC28J60 Ethernet controller was used. In order to obtain the perceived data more accurately and effectively, loss-based retransmission detection based on the ACK scheme was adopted in the wireless sensor network. Experimental results show that this method can effectively improve the reliability of the data.
