无人机系统是复杂的  UAV system is complex

再讲结构问题. 上次看京东的刘强东做演讲，说起用无人机配备去乡村农舍取豆腐，甚至贷款让乡村农舍买驴买磨手工磨豆腐. 我觉得他的构想最上层有创意的，但是整个结构有问题. 手工制造豆腐成本很高效率低. 无人机是高科技，要建立一个无人机网，操作，控制，系统，起降安排，起飞着陆地点，成本也不低，只为了豆腐一个产品来做，我觉得有点得不偿失. 如果为了制造手工豆腐，也可以把豆腐坊建在牧场边上，让一部分马和牛，或再养些驴，在吃草之余，可以来帮着推磨！这样交叉利用资源，又大规模生产，效益好多了.

Let's talk about structural issues. Last time I watched Liu Qiangdong of Jingdong gave a speech. He was talking about using drones to go to rural farmhouses to take tofu, even providing loan to allow farmhouses to buy mules, buy mills, and manually grind tofu. I think his concept is the most creative, but the whole structure has problems. The cost of hand-made tofu is very high and low efficiency. The drone is high-tech, to build a drone network, do operation, control, system, take-off and landing arrangements, take-off and landing location, the total cost is not low. Just for a product of tofu, I feel a little bit not worthwhile. If you want to make handmade tofu, you can also build the tofu shop on the edge of the pasture, let some horses and cattle, or raise some mule, in addition to grazing, they can help Pushing! This cross-utilization of resources, and mass production will bring much better benefits.

我觉得有必要在世界范围内建立一个无人机控制系统，为紧急事件，医疗事件，遥远递送，暂时寄送，服务. 记得在新疆旅行时，因为地域广茅，道路颠簸，开车要开好多小时. 筑路修路的费用不菲，维修的费用更不菲. 如果所传递的东西和修路的费用比，微不足道，那就可以考虑用无人机. 上次去柬埔寨，因为从吴哥窟到金边坐车要6小时，就放弃了去金边游玩.设立无人机系统需要严密的规划，要空中轨道的全球化标准设计，有控制中心，跟踪定位，各种型号的飞机，应用管控，紧急事故的救助等等. 如果能把飞行代价降下来，这将是一个很好的，地面物流网的补充，也是一个快速便捷的交通通道. 一带一路应该有广大应用的市场.

I feel that it is necessary to establish a drone control system around the world for emergency, medical events, remote delivery, temporary delivery, service. Remember when traveling in Xinjiang, because of the wild area, the road is bumpy, driving longer hours. Road construction is very expensive, and the cost of repair is even more expensive. If the cost of the things transferred comparing to road repairing costs is negligible, then you can consider using drones. Last time I went to Cambodia. Because from Angkor to the Phnom Penh, it took 6 hours to get  by car, I gave up. The establishment of the drone system requires strict planning, the global standard design of the air track, the control center, tracking and positioning, various types of aircraft, application control, emergency rescue, etc. If you can reduce the cost of flight, it will be a good complementary to the ground logistics network,  also a fast and convenient transportation channel. The Belt and Road should have a wide range of applications.
