大疆无人机在农业上的运用和讨论

大疆无人机在农业上的运用和讨论 技术的更新日新月异,时代带给我们许多更方便的科技,而无人机便是里面值得一说的产品,因为它不仅仅改善了我们的生活,也让农业生产有进一步的提升。大疆,作为整个无人机领域的佼佼者,我便从他开始说起。2015年,大疆发布了他们公司的第一台产品——MG-1 农业植保机. MG-1给整个农业领域以及无人机领域都带来了巨大的影响,然而用户不只是关心的是MG-1这个产品本身,更多的是怎样与传统农作方式的衔接并且开拓出了一种全新的工作模式进而对未来无人机的改进作出想法。 在传统的农药喷洒方式中,农民大多会使用一些手提式喷洒设备,但是这样的农作方式通常会影响菜苗的发育以及对人体造成伤害. 而大疆无人机设备却能解决这一系列痛点,农民们仅需要一人就可以对整片农田进行作业,而传统的农业需要多人,多机械,长时间. 这无疑会耗费大量的人力物力成本,而无人机毫无疑问可以减少大部分花在农业机器(尤其是喷洒设备)上的成本.这大大提高了工作效率(约40-50倍的人工效率)并且减少了农民的农作压力. 在2018,中国农业无人机保有量突破2万大关,年度作业面积突破1亿亩次,但问题也接踵而至,无人机尚且还算是个新兴领域,尤其是对于初次踏入农业领域的大疆. 如何做到无人机的广泛化使用成为了大疆需要面对的主要问题. 在中国,大部分的农民的受教育程度并不高(高中以上文化程度仅占11.62%),所以学习无人机的成本也会因此变高.其次,无人机的在农业上的涉足领域暂时还过于狭窄,大疆需要拓展无人机的功能,例如运用红外技术实时监测土壤湿度和温度以及特定时间的自动化收割.为了让无人机做到真正的无人农作,大疆可以通过激光脉冲对农场地形进行地理分析,并让电脑进行运算做到误差不大的自动判断系统,或是做出更简单的范围系统。进而使用通讯技术控制技术对更多农业设备进行联动以及操作。只需要使用者告诉无人机需要管理的区域,无人机便可以自动分析出最有效的处理办法,分析以及控制农业设备对这片区域进行播种,施肥,灌溉,除虫甚至收割。 时至今日,大疆在农业领域已经进行了大量的拓展,他们的新型产品也做出了播撒系统以及地形绘制来帮助农民进行更好的农作. 其次他们也尝试和当地政府合作来分配技术人员对农民进行无人机的科普以及教学来使无人机被更广泛的使用. 希望在不久的将来,我们会看见中国农业的全面无人机化 王威棋

Packable device keeps mosquitoes away in the boonies

Beyond heated insoles, Thermacell makes a variety of battery-powered gadgets for outdoor lovers, among them a line of mosquito repellers. The company is preparing to launch a lighter, more compact repeller designed to go deeper into the wilderness. The packable Backpacker Repeller drops Thermacell’s mosquito-fighting technology into your pack so you can easily carry it to even the most faraway backcountry destinations. We’ve used one of Thermacell’s larger repeller lanterns and can say that it’s an absolute pleasure. Thermacell claims 96 percent effectiveness against mosquitoes, black flies and other pesky flying…

The Death of Cubicles: Engineers Create the First Mobile Workstations

Got a smelly weirdo sitting next to you at work? Need a place to stick an intern? Well it looks like cubicle life as we know it is about to change. If some cutting-edge companies have their way, we may all soon be working from mobile workstations. What those spaces will look like all depends on the designer. Here’s a look at the most notable designs: • Michiel van der Kley’s Globus folds up into a globe and unfolds into a desk and a chair. • The ScooterDesk by Utilia may look uncomfortable, but its barstool design with…

New Mobile App Lets Scientists Nab Data Anywhere on Earth

To our graduate student readers: As if constant emails from your boss weren’t enough,  soon you’ll have no excuse to avoid the “got any data?” question—even when you’re out in the field. A new mobile app now lets researchers collect and analyze data from anywhere in the world, using their cell phones. It’s not all bad: The software could help you unload some of your work by allowing citizen scientists to snap pictures from their own backyards, and contribute them to research projects. The software, called EpiCollect, is especially useful for…

Harmless “T-Ray” Vision Sees Through Boxes, Walls and Skin

Call it the “X-ray vision” app: In several years, smartphones could come equipped with a microchip that lets users peer through boxes, walls and other objects. Rather than dangerous X-rays, however, the chip beams out waves in the harmless terahertz frequency, a little-used portion of the electromagnetic spectrum between microwaves and far-infrared. Terahertz generators historically have been bulky, expensive affairs. But now Caltech researchers have succeeded in crafting terahertz-emitting silicon chips that are smaller than a dime using a standard, inexpensive electronics manufacturing technique. The researchers harnessed an array of…

Machine Learning for Text Classification

Machine Learning for Text Classification Machine learning can used to classified different category of texts, by using various classifiers. The common machine learning classifiers are support vector machine, Naive Bayes and even ensemble models, such as stochastic gradient descent. Besides, deep learning neural network is also a choice for the text classification. Those classifiers and neural network enable us to category the text and even to find the author for the specific text. The general idea is that we input the text of specific category or author, and then we…

NEW SOLID OXIDE FUEL CELL TECHNOLOGY

Scientists are tirelessly working on sources of alternative energy so that we can have a better substitute for fossil fuels in near future. We know that sunlight, wind and geothermal sources of energy are better for everyone. But they also need efficient fuel cells for better utilization of power. Solid oxide fuel cells (SOFCs) seem promising enough for both stationary and mobile applications. Stationary use can cover residential applications to power plants. Mobile applications contain energy for ships at sea and in space, as well as for automobiles. Another advantage of the…

3 Implications of Memory-Boosting Devices

In fall, DARPA announced a major success in its Restoring Active Memory (RAM) program. Researchers implanted targeted electrical arrays in the brains of a few dozen volunteers — specifically in brain areas involved in memory. The researchers found a way to read out neural “key codes” associated with specific memories, and then fed those codes back into the volunteers’ brains as they tried to recall lists of items or directions to places. While the results are still preliminary, DARPA claims that the RAM technique has already achieved “promising results” in improving memory…

Miniature fuel cell to keep drones aloft for over an hour and phones charged for a week

Drones are being utilized in everything from parcel delivery to search and rescue, but their limited flight times are restricting their ability to travel great distances or stay for extended periods of time in the field. Simply adding more batteries, however, affects flight characteristics and reduces the load the drone can carry. To help solve this problem, researchers at the Pohang University of Science and Technology (Postech) have created a miniature fuel cell they claim not only provides enough energy to keep a drone in the sky for over an hour, but may…

How Trucks Can Make Delivery Drones a Reality

Delivery drones may still seem a ways off because of new U.S. commercial drone regulations requiring drones to stay within sight of their human operators on the ground. But such rules pose no problem for a U.S. startup that developed a drone capable of launching from delivery trucks and dropping off packages within the driver’s line of sight. The HorseFly drone developed by Workhorse Group, an electric vehicle company in Cincinnati, Ohio, is an octocopter designed to ride aboard a delivery truck. Once it gets a delivery mission, the drone can take off through the truck’s roof with a…
