Japan's "Asahi Shimbun" January 14 issue published a report entitled "The Government intends to strengthen the domestic drone company's assistance policy", said that small drones are being widely used in cargo transportation and other industries, the government decided to introduce assistance policies accordingly, Help domestic enterprises to develop or introduce drone models that can effectively respond to cyber-attacks.

It is reported that the Japanese government plans to submit a new bill at the general meeting of the parliament that opens on the 20th and strives to formally implement this summer.

At present, due to safety considerations, according to the provisions of the "Aeronautical Law" and other regulations, UAVs are restricted to fly around urban areas, nuclear power stations, and other important facilities and beyond the eyes of the operator. The Japanese government's policy is to relax some restrictions before 2022 to facilitate the use of drones in the logistics and security industries with severe shortages.

According to the report, with the popularization of 5G, mainstream drones may be capable of autonomous flight in the future, but there is also the possibility of being manipulated by third parties through hacking means or maliciously intercepting captured video images.

In order to prevent similar situations, the Japanese government will introduce a new law to provide support for aircraft models that have adopted security measures or for the introduction and development of autonomous flight systems. It is reported that when a venture capital company with a government background makes a capital contribution, it will relax some of the approval conditions and will also facilitate the relevant companies to obtain low-interest Japanese policy financial treasury financing.

Tethered drone Another function of this tether is data fiber optic cable. When natural disasters occur, communication physical facilities such as base stations are often damaged. The complete restoration takes time. The payload of a tethered drone is generally 5kg-15kg, and the flying height can reach 200 meters. Therefore, a micro base station can be placed, and Signals are transmitted through optical fibers. As long as the plane rises to 50 meters, it can grasp the situation within a few kilometers.

Generate multi-spectral images with the help of a multi-spectral imager equipped on the system to intuitively and comprehensively monitor the surface water environment quality status, and provide thematic maps of environmentally-friendly drone water eutrophication, water bloom, water transparency, and pollution status of suspended solids outlet In order to achieve the purpose of monitoring the water quality characteristics of environmental protection drones. The drone can also be equipped with a mobile atmospheric automatic monitoring platform to monitor the atmosphere in the target area. For pollution factors that cannot be monitored by the automatic monitoring platform, a sampler can be used to collect atmospheric samples in the air and send them back to the laboratory for analysis. The UAV remote sensing system has a strong ability to support safe operations, can enter high-risk areas to work, and effectively avoids the safety risks of monitoring and sampling personnel.

With the rapid development of drone technology, the application of drones in power plays an increasingly important role, mainly used for refined inspection of transmission line towers, an inspection of transmission line passages, emergency rescue, and three-dimensional transmission line passages. Modeling, transmission line barriers, and three-span measurements.

Recently, Zhejiang Zhoushan Unicom and State Grid Power Co., Ltd. carried out smart energy--5G drone power inspection flight test experiment with great success. This inspection line is the world's first main 500 kV submarine cable and is one of the reinsurance projects for 5G industry applications in Zhoushan Unicom, Zhejiang.

Affected by the low transmission speed and high latency of the communication network, the existing UAV power inspection data is stored in the TF card of the UAV, and it is exported and processed manually after the inspection, which is time-effective and interactive. There are deficiencies in intelligence. 5G has the characteristics of large bandwidth, low latency, and wide connectivity. 5G + UAV power inspection can effectively solve existing deficiencies and provide targeted solutions, which have great advantages in timeliness, reliability, interaction, and intelligence. Promotion.

The NAHB survey also found that while 20% of all home builders are likely to use drones over the next three years, 38% said it would not be possible to use drones at all. However, when drilling into the details, the builder's size comes into play again. Only 13% of builders started at less than 6 units, and they responded that they would use drones in the near future, while 41% of 100 units started or more said they would.
Across the construction industry, including the commercial and industrial sectors, the number of drones used is even more impressive. In fact, a report from the International Association of Self-Driving Vehicle Systems (AUVS I) in April found that the construction and infrastructure industry is one of the largest commercial users of drones.
AUVSI makes an assertion based on the Federal Aviation Administration's exemption data, which shows that the FAA has granted construction and infrastructure companies nearly 1,800 exemptions, accounting for nearly 60% of all industrial applications, and about 40 of the total 4,600 exemptions approved by the FAA. %. Allows companies to apply for FAA drone exemptions so that they do not have to meet the same airworthiness requirements as manned aircraft. The FAA expects to develop rules for drones this year.
In contrast to home builder drone usage figures, For ConstructionPros.com's analysis of AUVSI data found that almost all FAA exemptions issued to construction and infrastructure companies went to those with less than $ 1 million in revenue and less than 10 employees. Small business.
Drones have become a game-changing technology in the construction industry because they can monitor construction sites, take pictures, collect information, and then send it back to the project manager or design team.

If you want to compare the advantages and disadvantages of China and foreign civilian drones, China can be said to be the only country that has developed drones in a serious direction. There are several major development directions abroad: military, experiment, and entertainment. For large-scale applications, China is the most powerful. And in industrial-grade applications, China will pull other countries further and further in the future.
 
We only talk about industrial drone applications today. Industrial drones, according to their applications, can be divided into five main areas: plant protection, transportation, mapping, inspection (police security, power line inspection, petroleum pipelines, telecommunication cruise, forest fire-prevention ...), relaying.
 
In the industrial-grade market where technology has yet to mature, the market needs to be cultivated, and even users need education, which fields will have bright prospects?
 
There are many nuggets in the field of plant protection, but there are not many real earners, and there are even many companies that pay money to do plant protection. The price war in this area has become increasingly fierce, but the country has realized the importance of this industry and has started actual subsidy actions, which is a very important signal. With state subsidies, the plant protection industry will become China's leading industry in the world.
 
In the field of transportation, SF, JD.com, Youweis, Fanmei, and various...Continue Reading

On January 8, the first snowfall of 2020 fell in Xuzhou, Jiangsu. The State Grid Xuzhou Power Supply Company then organized employees to conduct special post-snow inspections of the 220 kV Fort Sand Line using drones. It is worth mentioning that the line inspector enters the inspection task into the flight control APP, and the drone inspects two of the linear pole towers without any manual intervention. The entire process takes only 12 minutes.
 
In recent years, due to complex transmission line paths, high tower heights, and wide distribution, the refined inspection of transmission towers has been a major problem. However, the previous track inspection of transmission line drones relied on manual collection. Although the technology is simple, quick to get started, and easy to implement, manual track collection has a large workload, slow speed, high cost, inflexible application scenarios, and cannot be fully adapted. Flexible and autonomous inspection requirements in multiple scenarios.
 
"Existing UAV inspection technologies for transmission lines often require manual track collection, which means that a drone needs to manually control the drone to fly once before the drone can achieve automatic flight. The embedded system is relatively closed, and it is impossible to customize the inspection function according to the actual needs of our site. "Zhao Changxin, director of the Transmission and Inspection Office of Xuzhou Company, revealed the shortcomings of the...Continue Reading
