Elevators are being used throughout human history, but modern elevator history is not older than 150 years. Steam and hydraulic elevators had already been used but they were not safe until the discovery of the clutch in 1852 by Elisha Otis. Following this discovery, the first elevator was installed in 1857, and elevators started to become an important part of daily life. The elevators were using hydraulic systems until the electric power utilization in the 1880s with the result of geared or gearless traction Geared Traction Machine the hydraulic ones. In electric elevators, the mechanisms were used to install above the elevator hoistway in a machine room. After the 1950s, hydraulic and ram elevators in which oil is used instead of steam returned because it was cheaper to put the machine room at the bottom of the building. The first electrical controls were started to be used by relay techniques which are the same as telephones in the 1970s. And in the 1980s, with new developments, microprocessors are introduced to elevator controls. An elevator controller is a system to control the elevators and the elevator control panel is a cabin that holds all of the components to control the elevator. The Elevator Control System holds all the power supply units, orchestrates all the operations, and ensures safety. Other functions like registering or canceling car calls, door control, measurement of the carload, and speed are handled by the elevator control panels.

Over the years, we have been under the shadow of the plague, and many countries and families have been affected. In the past year, the real estate market has been plunged into darkness because of the outbreak of the plague. During this period, some experts suggested restarting the shed reform plan, hoping to re-promote the development of the real estate market. But the current society is changing, and we cannot remain unchanged. Although the policy of rebuilding shantytowns has been welcomed by the people, it is not good news for them now. In this case, we still stick to the housing problem that is dominated by old renovations, however. Throughout the process of old city renovation, there has been a debate on how to install lifts in the old city. The so-called "old reform" is actually very familiar to everyone, because during the period of reform and opening up, many cities used "old reform" to solve residents' housing problems. The "old renovation" refers to the transformation of pipes, walls, environment and other aspects, rather than large-scale demolition. Of all the renovation projects, the installation of elevators was undoubtedly the most controversial. Because in this era, most of the old houses have already been built, so the old houses are not equipped with elevators, and people don't think there is anything wrong with it. But with the passage of time, the residents here are getting older and older, most of them are elderly people, so when they choose their own residence, the most important thing is convenience. Because old houses do not have lifts, it is very difficult to get in and out. Although old houses are generally 6 or 7 floors, it is difficult for the elderly to live in more than 4 floors. Therefore, many people want to install a lift in the old house during renovation. But for those who live on the first and second floors, installing an elevator will not help much. One is because the residents on the ground floor do not need to take the elevator, and the other is because it costs money to install. These people don't want to spend money, and the residents on the first and second floors will also be affected by the addition of elevators. In addition, the housing prices on the first and second floors were originally higher, but now that there are elevators, their advantages are gone. Due to the above reasons, most of the residents living on the 1st and 2nd floors are reluctant to accept the installation of lifts, which is a good example. So how do you please everyone? Now there is a new plan, which has been well received by all. To put it simply, all the storage services are handed over to a third-party company, and residents on each floor can choose a ride package according to their own needs, some for one year or one month. This can provide different solutions for each person according to their specific situation, and save their cost when taking the elevator to the greatest extent. In general, the current "bus elevator" and "custodial service" can better meet the needs of different families. This is the best way at present. People at the top can solve their daily problems through elevators, while people at the bottom don`t have to worry about installing elevators.

The home elevator market has also entered a stage of rapid development with the urbanization process and aging growth rate. According to statistics, during the period from 2011 to 2020, the compound growth rate of elevators in China reached 11.4%. With the development of society and the improvement of living standards, the output of elevators will continue to increase in the future. It is estimated that by 2026, the new increase of elevators in China will reach 2.01 million units. Home elevators, as a market segment of the elevator industry, have also experienced rapid growth driven by the development of the real estate industry. China is also the world's largest home elevator market. In the next year, it is expected that the domestic home elevator market will maintain an annual growth rate of 20%, and the average annual sales will reach 50 billion US dollars. So, what development trends will the home elevator market have in 2023? What should home elevator companies pay attention to? 1. Changes in the competition pattern of elevators The distribution of home elevator companies is relatively concentrated, mainly in Guangdong, Jiangsu, Shandong, Zhejiang, Hebei and other provinces, of which Guangdong and Jiangsu have the largest number of companies. my country's home elevator industry now has a complete industrial cluster, and elevator parts and complete machine manufacturing are also concentrated in the Yangtze River Delta, Pearl River Delta and Beijing-Tianjin-Hebei region, so Jiangsu, Guangdong and other places have become elevator manufacturing bases. 2. Foreign brands compete with domestic brands According to statistics, the domestic home elevator market size is about 150 billion yuan, of which foreign brands account for about 70%, while domestic brand competition is relatively scattered. There are no prominent brands that can monopolize a large market share, and domestic brands have a relatively large substitution space. 3. Complete range and technology improvement At present, the domestic home elevator market mainly includes three categories: screw elevators, traction elevators, and hydraulic elevators. The screw elevator adopts the nut-screw operation principle, has no machine room, zero bottom pit, self-contained shaft, and beautiful design. The traction elevator has mature technology, low noise and wide application range. Hydraulic elevators have low requirements for civil engineering, but there is a risk of oil leakage, and are gradually being eliminated by the market. The mainstream traction elevators on the market are all steel belt traction elevators, which have high space utilization rate, do not need pits like screw elevators, and have low civil construction difficulty. They are more popular types of home elevators on the market. At the same time, technologies such as face recognition, language control, and intelligent systems have also been added to make home elevators look more high-end. 4. Owners pursue aesthetic home quality A home elevator is not just an elevator, but a work of art. In addition to focusing on product quality, owners are also raising their aesthetic requirements. Home elevators are customized products, and each owner has different requirements for elevators. This also tests the design ability and aesthetic ability of home elevator manufacturers, and puts forward higher requirements for the elevator experience and atmosphere. 5. Possess perfect elevator maintenance as a key capability The domestic elevator market has huge potential, and related technical maintenance talents are also beginning to be popular. Enterprises with complete after-sales service teams and technical teams are ushering in excellent opportunities. Especially in the home elevator market as a vertical field, companies with complete quality assurance and self-operated service teams are quite likely to stand out from many competitors.

Several problems related to elevator equipment 1. The relationship between the air in the elevator car and the air in the building or building where the elevator equipment is located: The air flowing into the car from the building space when the machine room, hoistway, pit and car door are opened and closed. Although the air in a building is an overall concept, the air is pervasive, inseparable and unstoppable. The air in a certain area we are talking about refers to a specific time period or a specific occasion. Then if the air in any of the above spaces is not "fresh" or has "viruses including coronavirus", then the car space will become a "source" of infectious viruses. Therefore, the air quality and adjustment of the elevator car should not simply focus on the air in the car, but put the air quality of the above-mentioned spaces under "control". In this way, the above problems should be divided into two parts, one is the air quality and regulation of the car, and the other is the quality and regulation of the "source" air of the car air. The problem mentioned above is a practical problem based on the concept of "building automation", "building intelligence" and the scientific and technological issues involved in the building. The raging coronavirus in the country has brought threats to people's health and even life. Under such circumstances, it is necessary to consider the air circulation conditions inside the building and the possibility of blocking the spread of the virus from the building to the elevator car as much as possible. Of course, the elevator car cannot be used as a place to spread the virus. Therefore, it is necessary to control and adjust the air quality in the car subjectively and actively, so that the device for adjusting the air flow in the car has the function of "killing viruses" in addition to being responsible for the air flow in the car. Due to the pervasive mobility of the air, the quality of the car air is bound to depend on the air quality of other spaces in the building. Therefore, consider the air quality of the car together with the air quality of other spaces in the building, and consider it as a large system requirement and put it into overall consideration on the corresponding equipment to ensure that the air quality of the car is controlled and the air quality is adjusted. Make it possible, that's what we do. 2. How is the concept of building automation defined? Building automation includes air conditioning and ventilation monitoring system, water supply and drainage monitoring system, lighting monitoring system, power supply monitoring system, elevator operation monitoring system, comprehensive security system, fire monitoring system and structured integrated wiring system, etc., building automation system (BAS) ) is the management and control of all public mechanical and electrical equipment in the entire building. From the above concepts, we can know that building automation includes a ventilation monitoring system, including an elevator operation monitoring system. Of course, the air quality assurance system in the elevator car is also unified and integrated management in building automation, and should be included in the electromechanical equipment in the building. Such a definition clarifies the relationship between the large system of the building and the subsystems of each branch. The concept of the large system and the responsibilities of the branches are also clearly defined. It is necessary for each to fulfill its responsibilities. At the same time, we also need to know that building automation is the basic requirement of today's society for buildings and other buildings, including public facilities and public places. The core of this requirement is the basic and eternal theme of safety, energy saving and convenience. 3. Safety is the first priority of elevator equipment From the level of technology and the level of serving the society and the public, safety is the first attribute of elevator equipment, the first priority of the elevator industry, and the lifeline of elevator equipment. There must be no hypocrisy and untruth. So what is the safety situation in the elevator industry? It should be said that although everyone can admit that the importance of safety is also implemented in actual work, there are still safety problems that cause harm to elevator users. Several elevator equipment accidents in 2021 have sounded the alarm for us. Highly aware and take precautions. The safety of elevator equipment is an eternal theme. To understand safety research, it is necessary to analyze the principle, design, structure and manufacturing of the equipment in order to ensure safety. It is necessary to study the installation of the equipment and the maintenance during use. Study the failure of the above links. So what is failure? A piece of equipment such as an elevator's complete machine, components and electrical systems and components in the system lose the functions specified by the original design, which is called failure. Failure includes complete loss of original function, reduced function, serious damage or hidden danger, continued use will lose reliability and safety. It is important to understand the research of failure. The next step in failure analysis and failure performance is to put an end to failure within the service life of the equipment and eliminate the possibility of risk caused by failure. This is the goal we should strive for in our work.
