1.Stable and reliable protection device
(1)New generation landing door device
United elevator firstly apply the new generation landing door device in the indurstry.Which prevent safety lock from slippery,landing door bump,landing door unusual opening.The three new safety standards redefine the safety.
(2)Three dimensional infraed protector
Form curtain at the door of elevator,194 infrared beams protection
Make sensible response to any person or thing entering into detection scope with high level of safety performance.
(3)Emergent parking device
When passengers are trapped in elevator due to power off,the device will automatically switch to emergent operation
Make elevator leveling and open automatically through battery and release trapped passengers.
(4)Safety supervision system in elevator
Each maintenance service network station of United Elevator makes real-time supervision over elevator in operation through reserved intelligent system interface(remote supervision interface);exclude malfunction before occurrence to guarantee 24-hour and 365-day safe and reliable operation of elevator.
2.Highly efficient control system
(1)New generation of advanced control system
32-bit industrial ARM controller with high level of performance;precise speed signal with outstanding comfort;Combine all digital vectors inverter,make self-diagnosis and record through feedback to ensure efficiecy and safety of elevator;Perfect safety protection measures,be able to find emergencies and make corresponding protective measures when there is emergency arising to ensure safe and reliable operation;Strong anti-electromagnetic interference ability,strong antistatic electricity ability.
(2)Digital converter technology
Make adjustment over current and phase according to practical load and speed of lift car,Make real-time and precise control over driving force of main machine to ensure safe and stable elevator operation.
Long service Rapid staring speed Precise and stable operation
3.Intelligent passenger experience
(1)Intelligent management system
IC card intelligent identification system;function to set authority management;realize perfect combination between elevator control technology and computer communication technology,reinforcing greatly safety and intelligence of building management.
(2)Group control intelligent dispatching system
Adopt annular netword topology structure,make each system as independent main control cabinet to make signal deployment;make rapid calculation about optimal elevator operation pattern added with gene algorithm,relieving effectively heavy load in peak time of office building.
4.Energy saving environmental protection
(1)Permanent magnetic synchronous gearless machine system
Low heat loss,low operation cost,working efficiency reaches as high as 95%,save 40% energy compared with general traditional technology,at the meantime.solve thoroughly environmental pollution resulted from oil leak of traditional tractor,reaching free of maintenance and environmental protection of electric machine.
(2)Energy feedback device
Collect and store electric energy of no-load operation of elevator and then make feedback to elevator(electric mode)for use,saving more than 60% energy for elevator.
(2)LED automatic illumination system
Adopt LED lamp,saving more than 85% energy compared with traditional incandescent light bulb and flourescent lamp;at the meantime,after certain period with no call and waiting command,the illumination inside lift car will be automatically turned off,reaching the purpose of energy conservation
5.Lightening speed to arrive
(1)The idea of speed
Networks serial communication control system realizes detailed data exchange control,disperse processing with pertinence,improving response speed of elevator,guaranteeing highly-efficiency operation of elevator.
New generation of control system of microcomputer with greatly increasing coputing speed of CPU,ensuring high efficiency and precision of system control.
(2)The idea of stability
New lift car structure;add design of up and down fairing to reduce windage and improve comfort;
Novel cushion technique,floating connection of lift car to reduce vibration of building and improve stability and comfort greatly of operation.
Passenger Elevator Function
1. VVVF Drive
Motor rotating speed can be precisely adjusted to get smooth speed curve in elevator start, travel and stop, and gain the sound comfort
2. VVVF door operator
Motor rotating speed can be precisely adjusted to get more gentle and sensitive door machine start /stop
3. Independent running
The elevator can not respond to hall calling, but only respond to the command inside the car through the action switch
4. Automatic pass without stop
When the car is crowded with the passengers or the load is close to preset value, the car will automatically pass the calling landing in order to keep maximum travel efficiency
5. Automatically adjust door opening time
Door opening time can be automatically adjusted according to the difference between landing calling and car calling
6. Reopen with hall call
In the door shutting process, press reopen with hall call button can restart the door
7. Express door closing
When the elevator stops and opens the door, press door-shut button, the door will be closed immediately
8. Car stops and door open
The elevator decelerates and levels, the door only opens after the elevator comes to a complete stop
9. Car arrival gong
Arrival gong in the car top announces that the passengers arrive
10. Direct parking
It completely accords with distance principle with no crawling in the leveling. It greatly enhances the travel efficiency
11. Command register cancel
If you press the wrong floor command button in the car, twice continuous pressing of
same button can cancel the registered command
