first" safe" lift the inventor. " Security" this concept not only create lift industry,
but also for those who want to build more tall buildings to add more available
space design are open thoroughfare.
However it can be called the elevator ( electric energy to drive the elevator ) of
the product should be at the beginning of the twentieth Century emerged.
Elevator technology development trend
(1): green environmental protection concept is the development trend of
elevator. Have expert prophecy" who first introduced green products and
market of race to control, who will grasp the market competition initiative".
Development trend to basically have : the continuous improvement of product
design, production of environmental protection type low power consumption,
low noise, no leakage, no water leakage, no electromagnetic interference, no
oil pollution of the elevator hoistway guide. Elevator traction with nylon
synthetic fiber rope, steel belt without lubricating oil pollution traction mode.
Elevator decoration will use no (little ) environmental pollution material.
Elevator no-load rise and full of descending motor power regeneration
recycling technology. The installation of lifts will be installed without
scaffolding. Elevator parts in the production and use of the process has no
effect on the environment ( such as brake pads must not use asbestos ) and
materials can be recycled. (2) the application of Bluetooth technology in
elevator. Installation of elevators knows line, on line is time-consuming,
laborious, easy wrong job. If the control screen and calling system through the
Bluetooth wireless call will be connected to the elevator control another
revolution at the same time bring us enormous benefits. A installation period
will be reduced by more than 30%, the direct benefits of reduced installation
costs, customers from booking to use lift cycle cost reduce the ladder and
improve cash flow rate. B on the elevator using Bluetooth technology will
make the elevator control system using a large amount of the latest and
fastest computer, which will further improve the elevator machine reliability,
fault rate is greatly reduced, the control precision is further increased, the
result is the elevator more comfortable, more accurate flat layer. C is a good
solution to the elevator control and peripherals compatible and contact. In
particular can take the elevator and escalator induction to the building
management system or intelligent management district system.
The definition of PLC
Programmable controller is a digital electronic computers operating system,
specifically designed for applications in industrial environments designed. It
adopts a kind of programmable memory, for its internal storage procedures,
the implementation of logical, sequential control, timing, counting and
