Description

Intelligent elevator

Technical field

The utility model relates to a kind of Intelligent elevator.

Background technology

Existing elevator complete machine control principle is that PLC is according to speed reducing switch, flat bed signal, judge decelerate position, level position, service direction, and output frequency signal, actuation signal, direction signal are to frequency converter, frequency converter controls motor according to PLC instruction and runs, driven by motor reductor runs, and reductor again driven gear rotates drive elevator cage operation along track (tooth bar).

As shown in Figure 1, existing elevator is example by four stops, needs 6 speed reducing switch, and the effect of speed reducing switch is the position of location car; Need 1 leveling switch; Speed reducing switch is magnetic induction bistable switch, and after magnetic patch streaks near switch, switch can keep the state be switched on or switched off, and the state connected or disconnected depends on the direction that magnetic patch streaks, and magnetic patch is in the face of the magnetic pole of switch one side.Slow down under switch is arranged on 1 layer respectively, 2 layers upper to slow down, slow down under 2 layers, 3 layers above to slow down, slow down under 3 layers, 4 layers above to slow down, on these 6 deceleration points, and arrange perpendicular row, the magnetic patch of master cock is arranged on car, with cage operation, when car upwards runs or runs, streak each switch successively downwards, the state of switch can change successively.Be respectively 0-1-0-1-0-1 the state of 1 landing position switch is bottom-up; PLC can be judged the position of car according on off state, need the position of direction and the needs deceleration run, and according to these information output corresponding signals to frequency converter, frequency converter controls motor according to the instruction of PLC again and runs; Wherein, leveling switch is magnetic induction switch, and effect is, provides flat bed signal; Leveling switch is arranged on the top of car, and car all can have an induction magnetic patch to be arranged on and leveling switch correspondence position at the level position of each stop.

Existing elevator adopts inductive switch to slow down and level position for controlling, and shortcoming needs many cables (each deceleration inductive switch needs 13 core cable, and general four stop elevators, need about 150 ~ 180 meters of 3 core cables); Secondly debug process complexity (each deceleration, level position need to install magnetic patch, and magnetic patch position needs to install accurately); Moreover langding accuracy relative mistake (after debugging langding accuracy: ± 10mm); And do not have coder, start and stop slightly shaking, comfort is bad; Last each speed reducing switch, leveling switch positioning requirements are higher, and Installation and Debugging are wasted time and energy.

When elevator damages, maintainer can only looking up the fault at the scene, and system does not have failure code to show, and does not have remote-monitoring function yet, once elevator breaks down, service personnel can only arrive spot examination, so,

Require higher to the professional skill of service personnel.
