On the stay cables of the Baishazhou Yangtze River Bridge in Wuhan, a robot is crawling fast. On the sidewalk on the side, a technician clearly recorded the health of the inner wire of the cable through the monitoring terminal. In just 10 minutes, a 300-meter-long cable was tested. This is the first application of the sixth-generation “Explorer” bridge cable intelligent detection robot newly developed by the China Railway Bridge Research Institute on a bridge across the Yangtze River.
Technicians are operating the sixth-generation “Explorer” bridge cable intelligent inspection robot. It is understood that the bridge cable is composed of thousands of steel wires. Whether the steel wires are damaged or not is directly related to the safety of the bridge. Jiang Gan, deputy director of the Bridge Health Monitoring Center of the China Railway Bridge Research Institute, introduced that in the past, manual inspection of the stay cables required a manned gondola to be pulled up the bridge tower along the steel cable, and a 200-meter-long cable inspection required two or three people. It took half a day to complete. Not only is it extremely risky and affects normal traffic, it also cannot detect damage to the cable. Today, with the latest generation of inspection robots, one or two technicians can complete the inspection of a steel cable in just 10 minutes, covering both the surface and internal damage detection of the cable body, greatly improving the speed and accuracy of bridge inspection.
“This robot is only 30 kilograms, which is more than half the weight of the previous generation robot, and the speed is increased by 40%. Each inspection is like doing ‘NMR’ to the cable.” Director of the New Technology Institute of China Railway Bridge Research Institute Wang Xiang said that the robot adopts advanced CCD technology and industrial camera lens, and can also perform high-definition imaging during high-speed movement. The robot also realizes functions such as full-time six-wheel drive, climbing and returning, automatic navigation, and orientation positioning, which ensures the accuracy and safety of high-altitude detection.
The sixth-generation “Explorer” bridge cable intelligent inspection robot is testing the cable. The “Explorer” bridge cable intelligent inspection robot is one of the representative achievements of the new bridge intelligent inspection technology of China Railway Bridge Research Institute. Since the first domestic “Explorer” cable inspection robot came out in 2012 It has been iteratively upgraded in the practice of cross-river and cross-sea bridge engineering, and it has been updated to the sixth generation product. According to reports, its large-scale application will promote the progress of my country’s bridge inspection and evaluation technology and help China’s “bridge business card” to go global.
On March 9, in the power supply control room of Liugang Group’s cold rolling plant, an inspection robot is scanning the control panel.
China News Service, Liuzhou, March 9, in the power supply control room of the Liugang Group’s cold-rolling plant in Liuzhou City, Guangxi, a milky white intelligent inspection robot twisted its robotic arm and used the camera on the top to collect functions such as temperature measurement and data collection. , and check the data of the equipment in the control room one by one. This is the company’s first intelligent inspection robot.
“The use of manual inspections before, not only consumes manpower and material resources, but also has relatively broad criteria for judging whether the data is running normally. With this inspection robot, it can not only achieve real-time inspections 24 hours a day, but also in data collection and operation. The monitoring is also more accurate and efficient, which greatly improves the efficiency of daily inspections.” said Shi Zhiguang, the champion of the National Equipment Inspection Skills Competition and an electrical technician of the cold rolling mill.
The intelligent inspection robot is a new type of service robot. It is mainly used to monitor production equipment and provide timely feedback of equipment status in the system, so that technicians can quickly find problems for maintenance. In recent years, such new inspection robots have been widely used in electric power, tunnel, metallurgy and other fields, and the sales market is also further expanding. Relevant statistics show that from 2018 to 2020, the total demand for China’s inspection robot market is about 47.7 billion yuan, with an average annual demand of about 15.9 billion yuan. It is expected that the future market in the field of intelligent inspection will reach 100 billion yuan.
With the gradual integration of artificial intelligence with traditional industries, the Internet of Things, cloud computing, and 5G technologies have brought considerable economic and social benefits to enterprises, and promoted the restructuring and upgrading of the source end of the industry. The adjustment of China’s industrial structure has brought inspection robots to us. Rapid development. Taking the State Grid of China as an example, the intelligent power grid inspection robot can overcome the shortcomings of traditional manual inspection of substations and distribution stations, and the inspection results cannot be digitized, effectively saving inspection costs and improving the intelligent operation of the power grid system. level.
According to the requirements of the development plan formulated by the State Grid of China, from 2016 to 2020, the intelligent rate of newly built substations should be 100%, and about 8,000 new intelligent substations should be built. According to statistics, in 2019, the overall industry scale of China’s substation inspection robots will reach 40 billion to 55 billion yuan. In the future, such power grid inspection robots may become the “standard configuration” of the smart grid system and integrate with the construction of the entire grid intelligent system.
At present, although the market demand is strong, the market competition of intelligent inspection robots in China is not fierce. Relevant analysis points out that due to the multi-disciplinary knowledge involved in mathematics, mechanics, automation control and computers, and the need to pass strict certification by the state or a third-party authority, there are certain barriers to the manufacture of intelligent inspection robots, so there are few competitors in the industry. . At present, the only manufacturers are Shandong Luneng, Yi Jiahe, Zhejiang Guozi and so on.
The strong rigid demand and the high entry threshold have made the overall gross profit margin of the intelligent inspection robot industry reach more than 60%, with a high level of profitability. At present, the global intelligent inspection robot has entered industrialization from research. China clearly requires that the intelligent inspection robot industry needs to increase by 30% by 2021. In the future, the industry competition of intelligent inspection robots will become increasingly fierce.
In the past two years, when tourists stay in hotels in Tianjin, most of them will encounter a special “employee”. Although he is reinforced, he is proficient in all kinds of skills, such as being cute, leading the way, delivering meals… “The baby is walking, please don’t block the front area.” “I’m very happy to be able to ride the elevator with you. Please walk inside and give me the middle seat.” “Please give me a good review, I Mom will give me candy.” After 8:00 in the morning, the hotel receptionist received a call from the guest on the 7th floor who needed “two bottles of water”, so the task fell to the self-proclaimed “baby” On the robot waiter. The hotel staff handed the relevant items to the waiting robot waiter. After inputting the instructions, the robot waiter took the elevator and looked for the room by himself.
This guy who is less than 1 meter tall, can act like a spoiled child, and looks “cute” has attracted the attention of many people as soon as he appeared. Some children will always follow the robot, and they like it very much. a small video. In the process of work, the hotel service robot can not only shuttle through the corridors of the hotel without barriers, but also call the elevator to each floor. , while delivering the items to the door of the guest exactly, the one-way time is less than 3 minutes, saving 75% of labor costs.
After the whole process, it realizes the whole process of taking the elevator autonomously, avoiding roadblocks, finding rooms, calling customers, returning to the front desk, and automatically recharging. “I called the front desk this morning to ask for mineral water. I didn’t expect that the phone rang but it was a robot’s voice. I asked me to open the door to get the water. After I closed the cabin door, it went away by itself. It’s so cute!” This is Mr. Li, the tenant. The first time he met a robot waiter, he said that although he did see a robot when he walked into the hotel lobby, he always thought it was just a welcome decoration. He never thought that the current hotel service can be so intelligent.
There are not a few people who have the same experience as Mr. Li. Many residents said, “The most interesting thing is this robot. It can deliver things to the room and play a few times while taking the opportunity to order takeout.” After walking over the bumps on the ground and bumping, it would say ‘Oops, don’t get in my way’, and thought that it had fallen in love with this cute creature.”
“Some guests will even take the initiative to avoid them. Maybe the staff will push the dining car into the elevator and guests will have opinions, but in the face of a cute robot, who would have the heart to get angry? This is also a ‘bonus’ that comes with the hotel service robot.” Hong Jinhua, general manager of Wyndham Hotel Tianjin, said with a smile that the two hotel service robots in the lobby have been hired at the beginning of the hotel’s opening in 2021. They are old employees. During the epidemic prevention and control period, the robots played a great role. Great effect, “It has a 24L interior space, except for delivery of takeaways, slippers, toothbrushes, mineral water, hair dryers, bath towels or clothes hangers and other common items are no problem, staff and customers have reduced contact, more secure, Hygiene.” In addition, robots can give guests a sense of security. “Especially when delivering meals at night, for female guests, robots will feel more at ease.”
Vision sensors, obstacle avoidance sensors, microphones, speakers, PAD operation screens, WIFI, etc… On the hotel service robot, one by one high-tech equipment not only meets the needs of indoor scenes, but also protects the privacy of guests and realizes contactless services. It increases the satisfaction and experience of the guests, and replaces the boring or dangerous things for hotel staff to achieve a stable service level.
“It’s very common to use robots in hotels now!” In Hong Jinhua’s view, hotel service robots are on duty 24 hours a day, do not get sick, do not complain, and the monthly salary is approximately equal to the electricity bill. “We have more than 160 rooms every day. If there is a need to deliver goods at night, and the staff on duty cannot meet the needs of all guests, the robot is particularly useful.” For the guests, while providing convenience for life, they can also feel the black technology brought by the smart city. experience.
At present, more than 300 hotel service robots in Tianjin have started their “part-time work” life. In the face of the hotel application scenario under the normalization of the epidemic, the hotel robot research and development company has further launched an epidemic-proof version of the dual-cabin robot and put it into use. The built-in ultraviolet light can automatically disinfect the takeaway and other items in the cabin, and the first guest can be delivered to the hotel. After you need the items, you can go directly to the second guest’s room without returning to the lobby. The efficiency is nearly 30% higher than that of a single cabin.
It is understood that with the development of artificial intelligence technology, service robots are increasingly appearing in our lives. From factories, logistics to hospitals, to housekeeping and hotels, service robots are constantly breaking through the category of “mechanical arms” to bring people a more convenient life. With the continuous planning and layout of Tianjin, more “black technologies” are about to enter thousands of industries, reducing costs and increasing efficiency and stimulating vitality!
