Technology

The classical technology creates the comfortable riding experience
We apply the advanced micro-processing network control technology for LARSSON elevator. High performance CUP and large capacity storage space, CAN-BUS serial communication produce the extremely strong anti-interference capabilities and perfect elevator operation functions. The users can increase special functions according to the specific needs. At present, the modular, intelligent and extensive system, multi-functional serial interface, long-distance monitor technology etc. belong to the advanced control technology in the elevator industry.
The matured and reliable serial communication
The concise and reliable serial communication network is adopted between various control sub-systems in order to fulfill a series of the functions such as calling, command, group supervision signal, floor display etc. It greatly reduces the trouble possibilities out of circuit problem, largely enhances the reliability of the elevator travel. At the same time, it brings more convenient repair and maintenance to the elevator system.
It chooses the rare earth materials to fully merge the coaxial drive technology, the numeric variable frequency technology, the group-computer combined control technology with the efficient energy-saving, minimum travel cost, low heat dissipation, extremely high work efficiency. Com pared with the common traditional techniques, it can save more than 30% of the energy. And the gearless traction machine needs no renewal of the grease without any oil stain pollution. The low noise design produces a peaceful riding space for you.
Smooth start, quiet moving
LARSSON elevator special inverter takes the control theory of the advanced technology as the foundation,
The start, acceleration, brake curves are designed according to the ergonomic theory in order to get the finest coziness. It is a genuine current vector control variable frequency drive system.
Top advanced door operator system

LARSSON elevator applies the advanced VVVF variable voltage and variable frequency control technology to the elevator door operator system so as to ensure the smooth elevator door and quiet switch. What is more, the self-learning door load detector increases the sensitivity of the elevator door switching on/off. It monitors the variation of elevator door load on every floor. Automatically rectifying the most appropriate open/shut speed in every floor so as to guarantee the security and reliability.
