Abstract

The application of unmanned aerial vehicles (UAV) in Malaysia, or best known as a drone, is changing from time to time. Today, drones are used not only in the military, but also in agriculture. The use of drones became common in agriculture due to a reduction in cultivated land, labour shortages and obsolete methods. The spraying of pesticides and herbicides may also be carried out using drones. Furthermore, the time-consumed using drone is faster compared to the conventional method. On the market, there are different kinds and types of drone sprayers. Although the manufacturer has set the Standard Operating Procedure (SOP) for drone usage, the efficacy of spraying should first be examined because of Malaysia's weather and environmental factors which vary from other countries. The purpose of this paper is to investigate the effects of altitude and speed of the drone onto the coverage area during spraying application. In this study, a plot consisting of 0.5 Hectares situated at MARDI Seberang Perai was used. Three different speeds of 2 m/s, 3 m/s, and 4 m/s and three altitudes measured in heights of 1.5 m, 2.0 m, and 2.5 m from the top of the crop were tested. Wind speed and direction were recorded using an anemometer during the study. Water-sensitive paper was used during the experiment to examine the effect on spraying. In order to calculate the coverage area percentage, the spraying effect on water sensitive paper was analysed using ImageJ software. The results are expected to show which speed and altitude may contribute to the largest area of coverage percentage. The appropriate altitude and speed for the spraying operation on the basis of crop requirements can be concluded from the result which is 2 m from above crop at speed of 2.5 m/s.
不同飞行速度和飞行高度下喷淋无人机配水特性研究
无人驾驶飞行器(UAV)在马来西亚的应用,或最广为人知的无人机,不时发生变化。如今,无人机不仅用于军事,还用于农业。由于耕地减少、劳动力短缺和方法过时,无人机在农业中的使用变得普遍。喷洒杀虫剂和除草剂也可以使用无人机进行。此外,与传统方法相比,使用无人机消耗的时间更快。在市场上,有不同种类和类型的无人机喷雾器。虽然制造商已经制定了无人机使用的标准操作程序(SOP),但由于马来西亚的天气和环境因素与其他国家不同,因此首先应该检查喷洒效果。本文的目的是研究无人机在喷洒过程中飞行高度和飞行速度对覆盖区域的影响。在这项研究中,使用了位于MARDI Seberang Perai的一块0.5公顷的地块。测试了2米/秒、3米/秒和4米/秒三种不同的速度和距离作物顶部1.5米、2.0米和2.5米的三个高度。在研究过程中使用风速计记录风速和风向。试验采用水敏纸,考察其对喷雾效果的影响。利用ImageJ软件,对水敏纸的喷涂效果进行了分析,以计算其覆盖面积百分比。预计结果将显示哪种速度和高度可能对最大的覆盖面积百分比做出贡献。以2.5 m/s的喷施速度,在距作物上方2 m处,根据作物的要求得出适宜的喷施高度和速度。
