摘要
为了解决播种机山区作业时通信条件差的问题,针对多跳无线传感器网络数据收集协议中继转发节点选择算法效率不高的缺点,在播种机质量监测系统的设计上提出了一种基于多跳多信道的通信网络和高效中继节点算法,有效提高了播种机监测系统的工作效率和精度。为了实现多跳多信道通信,以4×4接收和发射天线为例,以自组织网络模型为依据,建立了多信道通信模型,为了实现高效中继节点,对比洪泛算法,引入了多层中继节点布局算法,从而提高了节点的传输效率。最后,以免耕播种机为研究对象,对播种机作业的质量监测系统进行了测试,结果表明:采用反馈调节的方式,种子正好播在沟穴中央,播种效果比传统播种机的播种效果有了明显的提升。同时,对播种机株距参数和漏播系数进行了测试,结果表明:播种机的各种性能符合国家精密播种机的设计标准。
In order to solve the poor communications operation mountain sowing machine problem in multi hop relay wire- less sensor network data gathering protocol forwarding node selection algorithm to overcome the inefficiency in the quality monitoring system design seeder and proposed a multi hop communication network multi channel and efficient algorithm based on relay nodes, thus effectively the monitoring system improves the work efficiency and precision seeder. In order to realize the multi hop communication channel, with 4 x 4transmitting and receiving antenna as an example, based on self organization network model as the basis, establish the multi channel communication model, in order to achieve effi- cient relay nodes, compared with flooding algorithm, introduces multi relay node placement algorithm, thereby improving the transmission efficiency of nodes. Finally, with no tillage sowing machine as the research object, the quality monitoring system of seeding was tested, the test results show that the use of feedback regulation, seeds can be sown in a ditch hole is central, seeding effect has been significantly improved than the traditional planting effect of spacing sowing machine parameters and leakage coefficient the test, the test results indicate that the various performance of the machine with the design standard of national precision seeder.
