The design of real-time monitoring system
for remote drug application
ABSTRACT
With the rapid development of modern agroforestry machinery, unmanned aerial vehicles (UAV) are widely used in the field of plant protection and medicine for their advantages, such as safety and efficiency. In order to monitor the quality of the UAV spray, a low cost and convenient unmanned aerial vehicle monitoring system is urgently needed on the market. This paper expounds the purpose and significance of the monitoring system; then reviews the development history of the world of the UAV, demonstrate the vigorous vitality of UAV development; then discusses the status quo of domestic and foreign security of the UAV, UAV show domestic plant protection compared with huge development space; thirdly the current situation ofthedevelopment of UAV surveillance system in our country abroad, expounds the monitoring system performance and characteristics, and also points out the current monitoring system is to flow and liquid cushion research vacancy spray; finally, summarize the design content, emphasizing the UAV remote monitoring system innovation.
Key words:unmanned aerial vehicle;remote monitor;drug application and plant protection;
1、 课题研究目的和意义
近年来，我国农林业现代化技术快速发展，大量先进科学技术应用于农林业生产中，在很大程度上提高了生产效率。植保无人机因其安全高效等众多显著优点正在逐步地取代人工植保。但在使用过程中，也出现了很多问题[1]。
目前无人机喷药作业时，一般由操纵人员目视飞机的飞行状况，根据目测和经验来控制无人机的飞行，带有较大的主观性和随机性，其作业的安全无法得到保证；并且我国的地域覆盖十分辽阔，地貌各异，作物多样，仅仅依靠操纵人员的感觉来控制无人机作业，作业质量和效率很难保证。结果就导致农户和机主常常因为喷药是否均匀、农药是否喷到其他地方造成污染等现象与飞机驾驶员发生争执。因此在农用无人机喷药性能检测市场上，急需一种价格低廉、操作简单又能达到实时监测飞机状态的喷药情况的装置，通过借助监控系统实时对无人机飞行信息和喷药状态进行检测。
