Abstract
The invention provides an elevator binary coding system which comprises a detection coding unit, a speed detection unit, a binary coding unit and a binary coding changing unit. The binary coding unit comprises a switch, and the detection coding unit detects the binary coding unit. According to the elevator binary coding system, the defects that a mechanical switch is used in an existing elevator and accordingly a system is complicated and prone to being damaged are overcome, a binary coding mode is adopted, the number of switches used in the system is effectively reduced, and accordingly the service life of the elevator system is prolonged.
Description
Technical field
The present invention relates to a kind of elevator, particularly a kind of elevator binary encoding system.
Background technology
Apparatus for controlling elevator hardware is made up of car operation board, Room gate signal, PLC, frequency converter, speed governing system, and frequency converter only completes speed-regulating function, and logic control part is completed by PLC.PLC is responsible for processing the logical relation of various signals, thereby sends start-stop signal to frequency converter, and frequency converter also flows to PLC by the mode of operation of itself simultaneously, forms two-way contact relation.System has also configured with electrical motor and has coaxially been connected rotary encoder and PG card, and the speed that completes detects and feedback, forms speed closed loop and position closed loop.This external system is necessary arrangement brake resistance also, and in the time that deceleration of elevator moves, electrical motor, in regenerative power generation state, to frequency converter feedback electric energy, suppresses vdc and raises.
Along with the continuous progress of elevator technology, the action that elevator need to be carried out is more and more, thereby in elevator, need increasing switch, cause installation and the configuration mode of elevator also to become increasingly complex, and mechanical switch also can often damage, but when mechanical switch damages, usually bring out safety misadventure, thereby mechanical switch will progressively be eliminated.
Summary of the invention
For addressing the above problem, the invention discloses a kind of elevator binary encoding system, this system overcomes existing elevator and adopts mechanical switch to cause complexity and the damageable defect of system, adopt binary encoding mode, effectively reduce the use amount of switch, reduce fault rate and the repair rate of elevator device, effectively reduce the cost that elevator is manufactured.
The invention provides a kind of elevator binary encoding system, comprise that detecting coding unit, speed detection unit, binary encoding unit and binary encoding changes unit, described binary encoding unit comprises switch, and described detection coding unit detects binary encoding unit.Object of the present invention designs a kind of elevator binary encoding system, this system overcomes existing elevator and adopts mechanical switch to cause complexity and the damageable defect of system, adopt binary encoding mode, effectively reduce the use amount of switch, thereby improved the service life of elevator device.
The one of a kind of elevator binary encoding system disclosed by the invention is improved, and described binary encoding changes unit and is arranged in elevator.This improvement changes unit by binary encoding and is arranged in elevator, can arrange according to the speed limit corresponding with it, guarantee that elevator all can being decelerated to of safety stop at each At The Height, thereby actv. extends the service life of elevator, meets user's demand.
The one of a kind of elevator binary encoding system disclosed by the invention is improved, and described switch is bistable magnetic swich.This improvement adopts bistable magnetic swich, and actv. has reduced the quantity that uses switch in elevator device, has simplified the operation control method of apparatus for controlling elevator, thereby actv. reduces the cost that elevator is manufactured.
