Description
Technical field
The utility model belongs to elevator control and Energy Saving Control field, particularly a kind of energy-saving control system for permanent magnet synchronous escalator.
Background technology
In today of rapid economic development, megastore, subway station, public transport transhipment station get more and more, and in these large scale business public places, the staircase transportation means that is absolutely necessary, as a kind of vehicle that transport passenger, not only successfully dwindle the distance between target, and made the large flow personnel transportation on ultrashort way (as floor, month interstation etc.) become possibility.Therefore, economist says: " appearance of escalator makes the desire of people You Liaoguang megastore ".Traffic scholar say: " be the application of escalator and moving sidewalk make that we can build station, airport large as far as possible ".The application of escalator has changed our life, and has become an important symbol of modern material progress.But meanwhile the high energy consumption of staircase has also greatly increased the operation cost of terminal client, has brought ill effect in today of energy growing tension to entire society.How rationally to utilize staircase, the electric energy of as far as possible saving its consumption just becomes a focus direction of our research.
As the core component of staircase operation---drive main frame, the technology that still generally adopts at present asynchronous dynamo+worm and gear to slow down, its applied motor peak efficiency is 80%, average effiiciency is only 76%, and worm and gear deceleration feature is: simple in structure, operate steadily, noise is moderate, it only carries out big retarding and comes than transmission the torque of lifting motor with one group of worm gear pair, cost is also lower, but this type of technology has following wretched insufficiency: efficiency low (driving efficiency of the domestic two worm gear pair generally adopting is only between 62～68%), energy consumption is high, the flank of tooth is easy to wear (reduces complete machine service life, increase repair and maintenance amount).The driving main frame net effciency that two kinds of technology are composited is only 51% left and right, has both caused the huge waste of the energy, has restricted again the lifting of staircase quality.
Escalator is as one of important transit equipment in city, also there is operation factor high (statistics shows that escalator moves average out to 10～16 hours every day), feature that operational process no-load ratio is higher (drive when unloaded the electric current of main motor and load phase difference little), in order to reduce the energy consumption of staircase, part manufacturer has adopted the technology that installs frequency-converting speed-governing control system additional, this type of application has realized the energy-conservation object of staircase really, but the energy that the overwhelming majority has all utilized braking resistor that potential load feedback is returned consumes with the form of heat energy, energy-saving effect is limited, can not fundamentally solve the energy-conservation problem of staircase.

2) mechanical wear is large, service life is short: owing to turning round more than 10 hour every day with constant speed, make staircase component produce unnecessary wearing and tearing and fatigue damage, and as serious in component wears such as handrail, fishback, step, motor and drop-gear boxs.The general this escalator life-span, about 10 years, exceedes after this time limit major part wearing and tearing quite serious, needs to change and could use.
3) fault rate higher, cause use cost high: because common escalator remains high-speed operation, make a large amount of consumable accessorys change number of times frequent, need a large amount of funds; Wearing and tearing increasing and cal val are high, also cause escalator fault rate to increase, and further cause customer using cost to rise, and the while also increases the maintenance capacity of staircase and affects normal use.
