PLC control of elevator operation experiment platform:
A, preface:
Human beings use lifting tools transport goods, personnel's history is very long. In early 2600 BC, the ancient egyptians built the pyramids when used in the most original lift platform, the basic principle of this system, there has been no changes: namely a balance things declining, load platform to rise.
With the development of science and technology and city senior with small high-rise building increases unceasingly, a motor powered vertical lifts, equipped with the box shape for multistory buildings, pod by people or shipped the goods, commonly known as automatic elevator. It has an elevator car, run in at least two columns of vertical or gradient < 15 ° rigid guide rail between. Elevator car size and structure form facilitate passengers discrepancy or loading and unloading goods. According to the
different requirements of elevator, elevator driver can adopt hydraulic drive (the mid 19th century began using
powder-spraying, still in the application), rack-and pinion, screw driven (1852, American host Otis developed wire rope ascending safety lift), drum driver (eighties, device drivers have further improved, such as motor driven by worm transmission wraping drum, adopting the balance weight), traction and drive (19 century, using a friction wheel drive, greatly increases the elevator of hoisting height). Now the elevator industry wide application of ways to upgrade - tractive type hoisting mechanism.
Second, the working principle of the elevator:
In traction type hoisting mechanism, steel wire hanging on tractive sheave and its end with elevator car connection, another end with heavy devices connected. Traction motor speed reducer drive through after tractive sheave rotation, rely on tractive rope and tractive sheave friction, thus facilitating the traction elevator elevator car up or down. Realization of elevator car and heavy lifting movement, achieve transportation purpose. Due to suspension gb7588 safety norms and heavy tractive wire rope and tractive sheave slot between have enough friction to overcome any position of elevator car side and for heavy side on
tractive wire rope tension of the poor, therefore ensuring gb7588 safety norms and for heavy as tractive sheave positive transfer and reversed and constantly rising and falling. Normally closed of drum brake on motors at work, make the elevator running loose sluice, lose electric braking, make the elevator car stop lifting, and in designated layer website maintain its stationary, for people and goods discrepancy. Elevator car is passengers or other body parts, load for reuse to balance the elevator car load, reduce the motor power. Compensation device designed to compensate for tractive rope in the movement of tension and weight change, make the traction motor load stability, elevator car to accurately docked. Electrical system realization of elevator motion control, finish at the same time selected layer, smooth layer, guns, lighting work. Directives calling system at any time display gb7588 safety norms movement direction and location floor position. Safety device ensure elevator safety of operation. Third, the elevator components:
(1) hardware parts
1 external: 1 - traction machine (winch/motor)
2 - tractive rope (wire rope, compensation ropes)
3 - elevator car (car door, elevator car bottom)
4 - for heavy device (for heavy, for heavy guide)
5 - guide (guide boots and guide rail clips, elevator car guide)
6 - safety device (speed device, safety clamp, buffer)
7 - well the wall 8-9 - tensioning devise termination devices 10 - door interlock
11 - signal manoeuvring system 12 - the hall
2 internal: 1 - axle box instructions circuit 2 -- vestibular calling circuit
3 - Lord drag motor circuits
4 - switch gate 5-6 - file layer display circuit button memory lamp circuit
7 - floor inspection 8 - smooth layer detection transmitter 9 - PLC circuit etc.

S7-200 PLC series small size
Elevator work environment in S7-200 PLC series small size, PLC working principle is the collection signal acquisition, signal output
and logic control at an organic whole, with elevator electric drive system to realize the elevator control all functions. PLC from receiving plate and manipulation of each layer of call summoning signal, the ladder box gb7588 safety norms and door system function signal and Wells road and frequency converter state signals, the process of judgment and computation realization of elevator integrating selected control. PLC in the output shown and monitoring signal while running direction to inverter issued, start-up, add/deceleration operation and braking elevator signal. Software flowchart figure:
Four, elevator main parameters:
Main parameters refers to the rated load and rated speed
Rated load Q (kg) is a leading manufacturer of elevator which is the basis of the load or the seller guarantee that the normal running of the load.
The rated speed v (m/s) is a leading manufacturer of elevator which is the basis of the by the seller guarantee that the normal movement and the elevator car speed.

Six, elevator control system principle diagram
Mainly by the axle box instructions circuit, vestibular calling circuit, main drag motor circuit, switch a gate, archives layer
display circuit, button memory lamp circuit, floor detection and smooth layer detection preach traps and PLC circuit and other members.
Seven, elevator working condition
1. Normal working condition:
(1) the elevator was detected hallway or axle box of call signal after this floor signal and axle box where floor signal comparison, through elected to choose to run modules.
(2) elevator by dragging the speed module-driven dc motor sports car box drag. Axle box movement speed to after
low-speed into medium-speed again, and to change for
high-speed high-speed operation to decelerate points.
(3) when elevator detect target storeys testing https://www.doczj.com/doc/0110267777.html,bined produce of the deceleration point signal, enter the deceleration state, from medium-speed into low-speed, and with low speed running to smooth layer is point to stop.
(4) smooth layer, after a certain delay opening after until encounter switch in place and the switch, Again after a certain delay to close in until they reach closed in place travel switch.
The elevator control system for real-time display of axle box is always floor.
2. Compulsory working condition:
As the initial position need to adjust or elevator need maintenance, shall set up a state in the state that the elevator does not respond to the normal calls, and can move to guide rail, down the breaking point between arbitrary position. Console
fire/repair button, allow the elevator to immediately stop original operation, and then press force upward (downlink) button, elevator uplink (downlink); Once let this button, the elevator to immediately stop when processing when ending usable resume normal work button to jump out of the elevator compulsory working state.
