多播种机作业系统设计——基于无线网络节点协同通信与聚合算法

在多播种机协同自动化作业过程中,由于农田环境的复杂性,其协同通信过程往往会受到干扰,且多播机间的通信效率较低,从而降低了播种机的作业速度和质量。随着节点中继技术的发展,利用协同中继,可以使单天线系统具有多天线的优点,形成一个协同通信系统,从而有效地提高了多终端设备的协同通信功能。为此,将无线传感网络协同通信系统引入到了多播种机协同作业控制系统中,并采用聚类算法对中继节点进行了优化,最后对系统的可行性进行了验证。由4台播种机同时作业时的实时定位测试发现,系统的定位效率较高,定位所需时间较短,且4台播种机在x和y向的定位精度都较高,从而验证了该方案的可行性。

Design of Operation System for Multiple Planter Based on Cooperative Communication and Aggregation Algorithm of Wireless Network Nodes

In the multi seeder cooperative automated operation process,because of the complexity of farmland environment,the cooperative communication process tends to interference,and multicast communication between the lower machine efficiency,thereby reducing the operating speed and quality of sowing machine. With the rapid development of relay technology,the use of cooperative relay,which can make the single antenna system has the advantages of multiple antennas,the formation of a cooperative communication system,which effectively improves the function of cooperative communication terminal equipment. Accordingly,the cooperative communication system of wireless sensor network is introduced into the cooperative operation control system of multi seeder,and the clustering algorithm is used to optimize the relay nodes. Finally,the feasibility of the system is verified. By the four sowing machines and real-time positioning during the operation of the test found that the positioning system efficiency,positioning in a shorter time,and the four sowing machines in X and y to the positioning accuracy is higher,so as to validate the feasibility of the scheme.
