Li Jianguo, general manager of Midea Building Technology Elevator Company, used the human body as a metaphor to introduce the technical points of Digital Elevator: "For example, the application of AI graphic image recognition, voice acquisition technology, new infrared, millimeter wave and other human perception technology sensors, laser ranging technology, etc. is to improve the perception ability of the elevator; The application of CPU chips with higher computing power, big data analysis, artificial intelligence, deep learning, neural network and other technologies improves the calculation and analysis ability of the algorithm, which makes the elevator smarter and smarter. " It is understood that before leaving the factory, every LINVOL elevator has to undergo a total of 513 quality tests of the whole elevator and its components, such as performance, protection, structure and function. The mechanical safety protection system is combined with the electrical safety protection design, and eight safety devices, such as emergency braking system, door interlock and speed limiter, are adopted to prevent elevator accidents to the maximum extent. On the software side, we can monitor the elevator’s operation status in real time through big data and Internet of Things technology, analyze the elevator’s operation status in time through big data logic algorithm, and transmit it to the elevator management platform through the network for intelligent analysis and preventive maintenance. In addition, Midea is equipped with AI, sensors and Internet of Things technologies for every digital elevator. The camera of AI can automatically identify dangerous goods and dangerous ladder riding behaviors, and initiate corresponding measures to prevent problems before they happen. As a part of the building, intelligent elevator can also improve the operation efficiency of the building. Li Jianguo introduced,The digital platform of iBUILDING in UILDING can automatically identify passengers’ identity information through the elevator eye system, and automatically guide people on nearby floors to take a ride by robot dispatch, so that passengers can be sent to the destination floor without button contact. "It turns out that the elevator stops in the middle during the peak period of use, and the single running time is long; Now, through a series of algorithms and digital intelligent applications, the single running time of the elevator can be shortened, running more times, and delivering more people to the destination floor. " At the same time, the intelligent passenger flow analysis system can also realize the priority of dispatching elevators on peak floors, shorten the operation efficiency of elevators by about 2/3, improve the comfort, and at the same time effectively reduce energy consumption, save energy and reduce carbon.codaBorrow a passage from A Tale of Two Cities by Dickens as the conclusion of this article: This is the best time and this is the worst time; This is the age of wisdom, this is the age of stupidity; This is the period of faith, this is the period of doubt; This is a bright season; This is the dark season; This is the spring of hope, and this is the winter of disappointment … Although the rivers and lakes of elevators in China are still under the feast of foreign investment, I believe that with time, domestic elevator brands will surely rise against the trend and flourish in the wind!
