猪舍内温度、湿度和有害气体浓度等多种环境因子是影响生猪养殖健康和生产水平的重要因素.针对目前集约化生猪养殖形势下复杂猪舍环境监测效率低,信息采集缺乏稳定性和准确性的问题,基于WSN动态协调节点优化的猪舍环境监控系统,提出一种采用动态的协调节点进行实时优化的低能耗无线传感器网络分簇路由算法LDCN.通过仿真实验,结果表明:该算法能够有效降低路由节点能量的消耗速率,延长了无线传感网络中节点的使用寿命,提高了网络的传输效率,保障了猪舍环境监控系统的高效稳定运行.

Various environmental factors such as temperature,humidity and harmful gas concentration in the pig house are important factors that affect the health and production level of pig breeding.In view of the current situation of intensive pig breeding,the monitoring efficiency of the complex pig house environment is low,and the information collection lacks stability and accuracy.This paper studies a pig house environment monitoring system based on WSN dynamic coordination node optimization,and proposes a low-energy wireless sensor network clustering routing algorithm LDCN based on dynamic coordination nodes.Based on the LEACH algorithm,the LDCN routing algorithm optimizes the communication distance between the routing node and the coordination node in real time by coordinating the dynamic changes of the node,thereby solving the problem of excessive energy consumption of the cluster head caused by the poor transmission distance.The author tries to construct an optimized algorithm for data transmission and communication in the process of monitoring the environment of the livestock house which extends the life of the network node in the wireless sensor network.Through simulation experiments,the results show that the algorithm can effectively reduce the energy consumption rate of routing nodes,prolong the service life of nodes in the wireless sensor network,improve the transmission efficiency of the network,and ensure the efficient and stable operation of the pig house environmental monitoring system.
