Abstract

The invention discloses a double digital signal processor(DSP)-based elevator drive, control and energy conservation integrated system and a double digital signal processor(DSP)-based elevator drive, control and energy conservation integrated method. The system comprises a rectifying module, a double DSP control module, an inversion module, a tractor module, a capacitor, a three-phase alternating current power supply and a supercapacitor module, wherein the double DSP control module is connected with the rectifying module, the supercapacitor module, the inversion module, the tractor module and a standard communication port respectively; the double DSP control module communicates with an upper computer or an elevator controller; the rectifying module is connected with the three-phase alternating current power supply; the inversion module is connected with the tractor module; the rectifying module is connected with the inversion module through two direct current buses; and the capacitor and the supercapacitor module are connected with the two direct current buses respectively. Tractor drive, control and energy conservation are integrated, and the safety of an elevator control system is improved.

Description

technical field [0001] The invention belongs to the field of elevator control, in particular to an elevator traction machine drive, control and energy-saving integrated system and method based on double DSP (digital signal processor). Background technique [0002] With the development of science and technology and the improvement of people's living standards, the use of elevators is becoming more and more common. According to the statistics of the China Elevator Association, as of 2011, the number of elevators in my country has reached 1.65 million units, and the production and consumption of elevators are both the first in the world. [0003] Due to many problems in elevator production, installation, operation and maintenance, and supervision and management, elevator accidents occur frequently across the country, and elevator operation has become a new hidden danger to urban public safety. How to improve the safety and reliability of elevators is related to the development...
