Smart elevator

In recent years, with the development of economy, the term "smart city" has become more and more popular with the public.So what is the smart city?"Smart city" is an important aspect of the strategy of "smart earth"."Smart earth" requires a more intelligent way, through a new generation of information technology to change the way people interact, improve real-time information processing capacity and induction and response speed,Enhance business flexibility and continuity and promote the development of our modern society.

Smart elevator

Elevator as a special equipment which closely related to the security of  people and enterprise,Its safety performance is one of the focus point of the whole society.Traditional elevator remote monitoring system acquisition signal is limited, the transmission speed is slow, and the signal real-time performance is poor and the tariff is serious.

With the rapid development of modern sensor technology and network technology, one of the key industry of our new generation technology-- Internet of things industry has become one of the most competitive area.With Internet of things technology has becoming more and more popular,Advanced signal acquisition mode can collect more detailed elevator information data, excellent network platform to ensure the real-time and reliable signal transmission.

Since 2009, It begun to use the “Internet of things” to focus on the remote monitoring of the elevator in Beijing. It transfer the running state of elevator ,running floor,running direction, door condition ,power condition ,Temperature and humidity, light ,load and other information to dynamic monitoring station.But these remote monitoring only to solve the elevator running status and the elevator passenger elevator status, which can not meet the overall safety of the elevator monitoring.

After the promulgation of the “special equipment safety law” in 2014,Our country has pay more and more attention to the safety of special equipment.As is known to all, in the inspection of the elevator, including the daily inspection, two times a month maintenance, inspection agencies regularly test (every year).Of course also includes the supervision mechanism on the use of units, maintenance units, supervision and inspection of the inspection agency.But the most import part is the daily inspection which responsible for the building user.The elevator remote monitoring has been implemented is mainly reflected in the elevator running state, equivalent to the replacement of a part of the  daily inspection.

（1）elevator maintenance

In recent years, the elevator maintenance costs and elevator maintenance personnel wages growing.there is a big contradiction between the increasing number of elevators and elevator maintenance personnel number , so the elevator maintenance quality gradually depends on the elevator maintenance personnel responsible.But in recent years due to the accident more and more elevator maintenance personnel maintenance is not in place, a strong sense of responsibility caused by, so improve elevator maintenance quality has become a priority among priorities.

We can set up sensors, video images, etc. in the machine room,car top and bottom pit to strengthen the maintenance of the elevator maintenance.It can be retrieved maintenance personnel maintenance process and maintenance content at any time.It make the maintenance units pay attention to dynamic elevator maintenance personnel timely,strength the charge to maintenance personnel, enhance the maintenance personnel's sense of responsibility and service quality.Further records of elevator maintenance time and content, reduce accidents caused by lack of elevator maintenance.

（2）Elevator emergency rescue

At the present stage of the elevator malfunction, staff car alarm to the monitoring center through the telephone intercom system, maintenance record is also the paper or manual entry storage system.This traditional elevator monitoring system has many shortcomings, such as the inability to take the initiative to the police, the monitoring efficiency is low, the detection of a single fault, high maintenance costs and so on.We can view the various state of the elevator through a variety of data acquisition,effectively get the first-hand information, and according to the fault information in time to arrange for emergency rescue and troubleshooting, in order to solve the response time, the car alarm device failure, etc..

（3）Elevator service smart city

The Internet of things plays a unique role in the elevator safety control .At the same time, the elevator can also become an unparalleled part of smart city.We need to intensify efforts to develop human services function.

The Internet of elevator seems to be far away from our daily life.But with the development and popularization of information technology,it will soon coming into our life.
