随着现代化农业科学技术的进步,大面积协同作业逐渐开始应用在机械自动化生产过程中,为了提高联合收获机械装置作业的生产效率,提出了一种多机协同控制的多跳无线局域网络,实现了多机大面积协同化作业控制。利用无线多跳网络,基于地形和地质条件,统一多机作业的速度,根据脱粒滚筒的转速和籽粒的损失率,对协同速度进行优化。为了验证设计的多跳无线局域网多速度协同控制的有效性,对多联合收割机的速度优化效果和籽粒的损失率进行了实验测试。由测试结果可以看出:采用多联合收割机前进速度协同控制后,其机械效率和籽粒的损失率都得到了明显的改善,从而验证了速度协同控制方法的可靠性,为大面积农作物收获机械自动化作业通信技术的研究提供了一种新的无线多跳网络优化方法。

Along with the development of modern agricultural science and technology progress,the application in mechanical automation production process appears in large collaboration areas. In order to improve the production efficiency in the operation of combine harvester device,it presents a multi aircraft cooperative control of multi hop wireless local area network,realizes the multi machine cooperative control of work in large areas. It uses wireless multi hop networks based on jointed multi machine operation speed to control topographic and geological conditions. According to the threshing roller speed and the grain loss rate,it optimizes the speed of coordination. In order to verify the validity of multi speed coordination control based on the multi hop wireless LAN design. it tests the loss optimization effect and the grain velocity on combine harvester rate by using multi combined harvester forward speed coordination control. The mechanical efficiency and the grain loss rate have been significantly improved,which verified the reliability of the speed control method of collaborative. The result provides a new kind of multi hop wireless network optimization method for the study of automation communication technology in the large area crop harvesting machinery.
