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。

Abstract:

In order to solve the problem of poor communication conditions in the sowing machine operation in mountainous area, aiming at the shortcomings of inefficient algorithm in the selection of relaying nodes for multi-hop wireless sensor network data collection protocol, a multi-hop Multi-channel communication network and efficient relay node algorithm, effectively improve the work of the seeder monitoring system efficiency and accuracy. In order to realize multi-hop multi-channel communication, a 4 × 4 receiving and transmitting antenna is taken as an example. Based on the self-organizing network model, a multi-channel communication model is established. In order to implement efficient relay nodes and contrast flooding algorithm, Relay node layout algorithm, thereby enhancing the node's transmission efficiency. Finally, the no-till planter was taken as the research object to test the quality monitoring system of seeder operation. The results showed that the seeds were sown in the center of ditch directly by the way of feedback regulation. The sowing effect was better than that of the traditional seeder Significant improvement. At the same time, the parameters of seeding plant and the leakage coefficient were tested. The results showed that the various performances of seeding machine conformed to the national precision seeding machine design standards.
