【摘要】：目前无人机行业发展如火如荼,其在农业植保方面的应用备受关注,地面站作为无人机的大脑也越来越受重视。纵观整个行业,缺少了一款能够真正地为农业植保无人机量身定制的地面站软件系统。本设计基于企业的需求,针对当前开源地面站存在的种种不足,力求设计出一款能够适用于农业植保行业的地面站软件系统。由于大部分地面站中采用的开源通信协议一般以明文进行数据传输,这样使得数据链路传输存在较大的安全隐患,对此,本文研究了相关的开源协议与加密校验算法,提出了一种农业植保无人机控制链路数据传输安全加密的方法,保证了控制链路数据传输的安全性。针对当前地面站航线规划功能的复杂性和我国农田区域的不规则性,在完成基本航线规划功能的基础上,本设计实现了一种智能化农田作业的自动航线生成算法,较大程度地降低了农田作业规划的难度。对于当前流行的开源地面站显示数据模块较为繁琐、农田作业数据针对性不强及地图订制不适用等问题,本设计在研究电子地图技术的基础上,针对农业植保无人机的作业数据进行详细定制,完成了植保机作业数据汇总显示功能。最后对整个系统的稳定性及正确性进行了覆盖测试。多次测试的结果表明,本植保机地面站能够有针对性地显示出植保机的作业数据和飞行姿态,实现的控制链路数据加密校验的方法安全可靠,使用智能化农田作业规划功能,大大降低了航线规划的难度。此外,还对植保机的作业效果进行了雾滴测试,并对测试结果进行了仔细分析。
[Abstract]:At present, the UAV industry is developing in full swing, and its application in agricultural plant protection has attracted much attention, and more attention has been paid to ground station as the brain of UAV. Throughout the industry, there is a lack of ground station software that can really be customized for agricultural plant protection drones. This design is based on the needs of the enterprise, aiming at the shortcomings of the current open source ground station, and makes every effort to design a ground station software system that can be applied to the agricultural plant protection industry. Because the open source communication protocols used in most earth stations generally transmit data in clear text, there is a great security hazard for data link transmission. In this paper, the open source protocols and encryption verification algorithms are studied. A secure encryption method for the control link data transmission of agricultural plant protection UAV is proposed to ensure the security of the control link data transmission. In view of the complexity of the current ground station route planning function and the irregularity of the farmland area in our country, on the basis of completing the basic route planning function, this paper designs and implements an automatic route generation algorithm for intelligent farmland operation. To a large extent, the difficulty of farmland operation planning is reduced. To the current popular open source ground station display data module is more cumbersome, farmland operation data pertinence is not strong and map customization is not applicable, this design is based on the research of electronic map technology. The operation data of agricultural plant protection UAV is customized in detail, and the function of collecting and displaying the data of plant protection UAV is completed. Finally, the stability and correctness of the whole system are tested. The results of many tests show that the ground station of the plant protection machine can display the operation data and flight attitude of the plant protection machine pertinently, realize the method of encrypting verification of control link data, and use the function of intelligent farmland operation planning. Greatly reduced the difficulty of route planning. In addition, the effect of plant protection machine was tested, and the test results were analyzed carefully.
