Elevators are a commonly used tool for daily travel, and their usage is constantly increasing. According to data released by the General Administration of Quality Supervision, Inspection and Quarantine, the number of registered elevators in China reached 3.598 million in 2014, and it is expected to add another 600000 to 650000 in 2015. China has become the world's largest country in terms of elevator ownership, annual production, and annual growth, with Shanghai and Beijing ranking among the top two cities in the world in terms of elevator ownership. Although elevator quality and safety issues have become increasingly prominent with the increase in the number of elevators in use, due to unclear responsibility for elevator management, unsuitable selection, configuration, and usage conditions, inadequate maintenance and upkeep, unsmooth channels for the use of residential special maintenance funds, and the gradual increase in old elevators, elevator accidents occur from time to time, and there are still many malfunctions such as elevator entrapment. There is still a significant gap between the level of elevator safety and the increasing safety and convenience needs of the people.

On July 16, 2014, the Guangzhou Quality and Technical Supervision Bureau released data showing that in the first half of 2014, Guangzhou handled a total of 2562 cases of elevator trapped people, 1386 cases of malfunctions, and rescued 6947 trapped people. Among them, 70% of elevator failures in June occurred in residential areas.

In 2015, Premier Li Keqiang proposed for the first time in his government work report to formulate an "Internet" action plan, promote the integration of mobile Internet, cloud computing, big data, Internet of Things, etc. with modern manufacturing, and promote the healthy development of e-commerce, industrial Internet, and Internet finance? This has also become a new issue in the elevator industry.

The application of IoT technology in Chinese elevators can be divided into three stages. In the first stage, some elevator manufacturers in China took the lead in establishing remote monitoring systems for elevators through wired telephone networking, which was the prototype of elevator IoT applications. Due to the limited number of wireless base stations and unstable signals at that time, only telephone lines could be used to physically connect the elevator with the manufacturer's monitoring center or city monitoring platform. Due to the limitations of on-site wiring and the expensive cost of telephone landlines, the advancement of this technology is not easy, and most other manufacturers are in a wait-and-see state.

With the development of mobile communication technology and the continuous construction of digital base stations, as well as the expansion of mobile digital network coverage, elevator manufacturers have quickly upgraded their wired remote monitoring systems to wireless remote monitoring systems. This is the second stage of elevator IoT development, promoting the construction of emergency platforms in cities such as Hangzhou, Nanjing, and Guangzhou. The elevator wireless remote monitoring and alarm system adopts wireless digital signal transmission, which only requires on-site mobile signal coverage. It is easy to install and not limited by building wiring. It has functions such as automatic abnormal warning, automatic alarm for personnel closure, automatic fault reporting, remote two-way communication, and active status inquiry. From the actual operation effect, this system greatly enhances the timeliness of elevator fault alarm, improves the efficiency of elevator maintenance, guarantees the quality of maintenance, significantly reduces the accident rate, and effectively improves the safety level of elevator operation.

The integration and development of the Internet and traditional industries such as elevator manufacturing and maintenance under Innovation 2.0 presents a new form and new business type. As one of the earliest industrial sectors in China to open up to the outside world, the Chinese elevator industry has long rid itself of the outdated image of traditional manufacturing as "crude, stupid, silly, and large". It has jumped to the forefront of the international market in terms of market size and technical standards, and has already entered the stage of "Innovation 2.0". With the development of the new generation of information technology, domestic mainstream elevator enterprises are reshaping the new forms of the new generation of information technology, such as elevator Internet of Things, cloud computing, social computing, big data, which is the "Internet" of the elevator industry - Internet elevator information (cloud media), Internet elevator intelligence (passenger flow intelligent management system), Internet elevator safety (new wireless remote monitoring system). Among them, "Internet elevator safety" is the top priority, and it is also the third stage of the development of the Internet of Things for elevators. Industry 4.0, represented by "Internet elevator safety", is bound to break the traditional thinking in elevator procurement, management, supervision and other fields, and revolutionize the elevator industry from the whole process of elevator design, production, sales, installation, maintenance, transformation, replacement, management and supervision, which will help to accelerate the formation of a long-term mechanism for elevator safety that is "fully responsible for enterprises, unified government leadership, joint supervision by departments, inspection technology checks, and broad social participation".
