Abstract
The invention relates to the technical field of elevators, in particular to an outage position recognition device and a protection method. The outage position recognition device comprises a speed governor of an elevator, a frequency converter and a main control panel, wherein the speed governor is additionally provided with an A and B phase encoder which can reflect the actual moving position of a lift car. A direct-current busbar of the frequency converter is electrically connected with the A and B phase encoder after conversion. Four super-capacitors are arranged in the side where the main control panel is located, and the four super-capacitors supply electricity to a pulse circuit of the main control panel and a CPU. The outage position recognition device further comprises an absolute value flat bed sensor used for obtaining floor signals of the lift car, wherein the absolute value flat bed sensor is connected with the main control panel. When outage of the elevator occurs, the position of the lift car will not be lost, correcting time of the floor position of the elevator is relatively short, and great convenience is brought to users.
Description
Technical field
The present invention relates to the elevator technology field, relate in particular to a kind of de-energized means of identification and guard method.
Background technology
Elevator be a kind of be the vertical conveyor of power with the electrical motor, case shape gondola is housed, be used for tier building and take advantage of people or carrying goods.Elevator is as the transport facility of vertical direction, become important Architectural Equipment in skyscraper and public place and indispensable.Along with the development of computer technology, automatic technology and Power Electronic Technique, modem elevator has become typical electromechanical integrated product.Raising along with whole national economy strength, the people's personal consumption level rises appreciably, the real estate developer releases medium-to-high grade little high level and high-rise residential building one after another energetically, has driven increasing rapidly of residential lift, becomes the main growth point in whole elevator market.
Traditional elevator, when elevator had a power failure, because inertia or the steel rope of car skid at traction sheave, the elevator master control board can't recognize the actual position of car, thereby cause losing of car position, when powering on again, elevator need be got back to end station (minimum or uppermost storey) and proofread and correct, and the speed of returning flat bed this moment is slow, if elevator floor is than higher, just run into powering-off state frequently, it is long that elevator is proofreaied and correct time of floor position so, brings great inconvenience to the user.
Summary of the invention
The objective of the invention is to provides a kind of de-energized means of identification and recognition methods at the deficiencies in the prior art, when elevator has a power failure, can not cause losing of car position, and the time ratio of elevator correction floor position is shorter, has great convenience for the user.
For achieving the above object, the present invention adopts following technical scheme: a kind of de-energized means of identification, and it comprises velocity limiter, frequency converter and the master control board of elevator, described velocity limiter increase has A, the B phase coder of the actual position that can reflect that car moves; The dc bus of described frequency converter is electrically connected A, B phase coder through after the conversion; Described master control board side is built-in with 4 super capacitors, and 4 super capacitors are powered to pulse circuit and the CPU of master control board, and it also comprises the absolute value flat bed inductor be used to the floor signal that obtains car, and absolute value flat bed inductor connects described master control board.
Described A, B phase coder connect described master control board by electric capacity 2nF.
A kind of de-energized recognition methods, a, increase A, the B phase coder that can reflect the actual position that car moves at the velocity limiter of elevator, in the moment of outage, utilize the voltage of frequency changer direct current bus, the A of voltage DC5V, the B phase coder that are the PG card are powered, and prevent lift car because inertia or steel rope skid and cause losing of car position; B, at built-in 4 super capacitors of master control board side, when when outage, pulse circuit and the CPU to master control board powers by super capacitor, this moment, the software of master control board only calculated the car position pulse, car position is deposited among the EEPROM, and need not proofread and correct the position of car when powering on next time; The floor signal of c, car adopts absolute value flat bed inductor to obtain, when elevator carries out the hoistway position self study, can record the position of each floor, be pulse count, when outage, if not at leveling zone, position according to the CPU record, return flat bed nearby, and compare with the floor of self study, thereby guarantee the actual position of car.
Beneficial effect of the present invention is: a kind of de-energized means of identification of the present invention and recognition methods, when elevator has a power failure, can not cause losing of car position, and the time ratio of elevator correction floor position is shorter, has great convenience for the user.
