Abstract
The utility model relates to a kind of elevator variable frequency speed governing system based on patronage, comprise car operation board, Room gate signal, the light shading type opto-electronic pickup being divided into door both sides, the car Room, PLC, frequency converter, towing machine and rotary encoder, car operation board, Room gate signal, light shading type opto-electronic pickup are connected with PLC respectively, PLC and frequency converter interconnected, PG card is inserted with in the expansion slot of frequency converter, rotary encoder and towing machine are coaxially connected and feedback pulse are exported to PG card, and frequency converter is connected to towing machine.The utility model is by arranging light shading type opto-electronic pickup at door place, the car Room, the patronage entering elevator can be judged, be also provided with further and be convenient to further accurately to judge that passenger enters car or walks out car and be also configured with the real-time Weighing module of car.Controller (PLC) calculates the desirable running velocity of car in conjunction with number in car and passenger weight.And when car is idle, the running velocity of car is dropped to minimum.
Description
Technical field
The utility model relates to a kind of jacking equipment, is specifically related to a kind of elevator.
Background technology
Along with modern economy and townie development, elevator becomes the requisite walking-replacing tool of people's daily life, and the impact that the quality of elevator performance is lived on people is more and more significant.
There are some researches show, in various electrically increasingly energy-conservation today, elevator becomes " rich and influential family " of power consumption in building.Elevator is when high-speed cruising, and the energy of consumption is maximum.But again can not in order to energy-conservation and the speed of elevator is reduced because as large in the stream of people in rush hour amount that is on duty time need elevator high-speed cruising the stream of people to be disperseed rapidly.
In addition, except the static state that the requirement of elevator dispatching controls except general industry, dynamic property, its comfort index is also an important content.Ensure that the key of traveling comfort is to make elevator by desirable given speed curve motion.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of elevator variable frequency speed governing system that can regulate elevator speed based on patronage change in car.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of elevator variable frequency speed governing system based on patronage, comprise car operation board, Room gate signal, be divided into the light shading type opto-electronic pickup of door both sides, the car Room, PLC, frequency converter, towing machine and rotary encoder, described car operation board, Room gate signal, light shading type opto-electronic pickup is connected with described PLC respectively, described PLC and described frequency converter interconnected, PG card is inserted with in the expansion slot of described frequency converter, described rotary encoder is coaxially connected with described towing machine and feedback pulse is exported to PG card, described frequency converter is connected to described towing machine.
Further, in order to carry out elevator governor control in conjunction with car actual loading beyond number parameter, also comprise the real-time Weighing module of car, the signal of the real-time Weighing module of described car outputs to PLC.
Further, described frequency converter adopts the digital frequency converter of peace river VS-616G5 type.
The beneficial effects of the utility model are:
The utility model is by arranging light shading type opto-electronic pickup at door place, the car Room, the patronage entering elevator can be judged, be also provided with further and be convenient to further accurately to judge that passenger enters car or walks out car and be also configured with the real-time Weighing module of car.Controller (PLC) calculates the desirable running velocity of car in conjunction with patronage in car.And when car is idle, the running velocity of car is dropped to minimum.
In addition, seem level and smooth not lofty when changing in order to make the speed of elevator, frequency converter and rotary encoder is also comprised in the utility model, rotary encoder is coaxially connected with described towing machine and feedback pulse is exported to the PG card be plugged in frequency converter, frequency converter is more level and smooth according to the delivery curve of actual feedback adjustment voltage or electric current, thus make the passenger in car take advantage of pedestal to test to reach best.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the elevator variable frequency speed governing system based on patronage of the present utility model is described further.
Fig. 1 is the structural representation based on the elevator variable frequency speed governing system of patronage in the utility model.
Detailed description of the invention
Embodiment
According to Fig. 1, the elevator variable frequency speed governing system based on patronage in the utility model, comprises car operation board, Room gate signal, the light shading type opto-electronic pickup being divided into door both sides, the car Room, PLC, frequency converter, towing machine and rotary encoder.
Wherein, car operation board, Room gate signal, light shading type opto-electronic pickup are connected with PLC respectively, PLC and frequency converter interconnected.
PG card is inserted with in the expansion slot of frequency converter.Frequency converter adopts the digital frequency converter of peace river VS-616G5 type.Because the startup of VS-616G5 frequency converter, braking have the feature of the S curve that can regulate arbitrarily and zero-frequency still exportable 150% moment, be equipped with high-precision rotary encoder control accuracy and can reach 0.01-0.02%, make elevator ride comfort good, zero-speed band-type brake, langding accuracy is high.
Certainly proceed from reality, also can select the frequency converter of other type or kind.
Rotary encoder and towing machine are coaxially connected and feedback pulse are exported to PG card, and frequency converter is connected to towing machine.
In order to carry out elevator governor control in conjunction with car actual loading beyond number parameter, also comprise the real-time Weighing module of car, the signal of the real-time Weighing module of car outputs to PLC.
Light shading type opto-electronic pickup in the utility model can record the patronage that enters elevator and be transferred to control PLC, and is controlled the running velocity of elevator further by PLC.
PLC calculates the desirable running velocity of car in conjunction with patronage in car.And when car is idle, the running velocity of car is dropped to minimum.
Of the present utility modelly be not limited to above-described embodiment; the technical scheme of each embodiment above-mentioned of the present utility model combined crosswise can form new technical scheme each other; all employings are equal to the technical scheme of replacing and being formed in addition, all drop in the protection domain of the utility model requirement.
