摘　　要： 针对规模化兔场易产生的环境恶化快、配种繁殖乱、近交衰退、管理效率低等问题,该文基于无线传感器网络、网络通信等物联网技术,设计了规模化兔场生产监管系统。在实现生产过程管理的同时,重点实现了规模化兔场的远程环境监测与亲缘关系分析功能。设计研制了低功耗兔舍环境监测节点,利用多传感器采集兔舍内氨气浓度、空气温湿度等环境数据,通过节点间自组网的形式构建了兔舍环境监测无线传感器网络,实现了兔舍养殖环境参数的远程传输与在线监测;基于近交系数与亲缘系数的公式模型,对种兔的遗传信息进行存储、计算与分析,实现了种兔亲缘关系的自动分析,最大限度的降低兔体质量受近交影响的风险。该系统已在广东骏威农业有限公司应用,结果表明与人工监管兔舍相比,系统监管兔舍仔兔存活率提高了5.15%,种兔死亡率下降了3.33%,均达到差异显著水平(P<0.05),企业生产效率和经济效益也得到全面改善。 Farm raised rabbit has high yield, low cost, and economic efficiency, etc. However, along with the improvement of production scale, there exit issues of environmental degradation, breeding disorder of baby rabbit, inbreeding depression, low efficiency of management. Currently, livestock breeding production supervision system has been researched widely, but the rabbit as the research object for such system is rare. For rabbit fast pace of breeding habit, environment is easy to be deteriorated, and focusing on the automatic monitoring of the environment and genetic relationship analysis for large scale rabbit farm production supervision is rarely reported. Based on the characteristics and existing problems of rabbit breeding habits, and use of wireless sensor network, Internet technology such as network communication, in this study, we designed a large scale rabbit farm production supervision system. The system realized rabbit farm production management, business management, business analysis and the basic management functions at the same time. These components in the system were the keys for applying the remote environment monitoring and genetic relationship analysis function. Aiming at the problem that the large-scale rabbit breeding is easy to be influenced by environment, such as air temperature, humidity and ammonia, and for the design and development of the low power consumption rabbit's environmental monitoring node, we placed 2~3 sensor nodes in each rabbit house. The use of multiple sensors to collect rabbit inner environmental data of air temperature and humidity, ammonia concentration and other environmental data was constructed by ad-hoc network between the nodes in the form of large-scale rabbit farm environmental monitoring wireless sensor network(WSN). As such, the realization of the rabbit breeding environment parameters can be on-line monitored based on remote transmission and monitoring results via a Web interface for data visualization display, query and trend of early warning indicators.
