Description

Apparatus for controlling elevator
Technical field
Invention relates to a kind of apparatus for controlling elevator of control able to programme.
Background technology
Fig. 2 is the block diagram of existing elevator control gear.
In Fig. 2, the 1st, the source of AC of civil power (calling civil power in the following text), the 2nd, electrical motors such as induction motor (IM), permanent-magnet synchronous electric motor, by driving the method for towing machine 3 rotations, the lift car 5 and the counterweight 6 that are connected in steel rope 4 two ends are moved, the passenger in the lift car 5 is transported to the floor of regulation.
Rectifier 11 is made of diode etc., and the alternating current that mains supply 1 is provided carries out rectification it is transformed to direct current (DC).Inverter 15 is made of transistor or IGBT etc., direct current (DC) is transformed to the alternating current of variable voltage variable frequency.Controller 8 determines the starting of elevators and stops, generating its position, speed command simultaneously.Inverter control circuit 13 utilizes the current feedback and the velocity feedback that is installed on the coder 7 on the towing machine 3 of current probe 12 according to the instruction of controller 8, and electrical motor 2 is rotated driving, realizes position, the speed control of elevator.At this moment, inverter control circuit 13 is controlled by output voltage, the frequency of 14 pairs of inverters 15 of gate driver circuit.
The counterweight 6 of elevator is set at the weight that can realize balance under the situation that lift car 5 has suitable number to take.For example when the state of equilibrium elevator moves, when quickening, want consumed power, otherwise can make the speed energy conversion of savings when slowing down is electric energy with raising speed.But in general elevator, being to utilize regeneration resistance control circuit 17, is that thermal energy consumption is fallen with regeneration resistance 16 with the speed energy conversion.
In so existing elevator control gear, provide electric power to make the elevator operation by civil power 1 usually.
In above-mentioned existing elevator control gear, be transformed to heat exhaustion and fall because the electric power that produces when elevator regenerated is reproduced resistance 16, therefore wish its effective utilization.Again, the afternoon electricity needs of hot summer peaks now, needs to reduce the power consumption of this time period.
Also have, the instantaneous power during the elevator operation is big, and the time that stops is long, so average consumprion power is little.But the electricity charge are to be made of the energy charge that makes that the basic charge as per installed capacity of contract power decision and power consumption determine, though therefore power consumption is few under the situation of elevator, make energy charge less by what power consumption determined, because instantaneous power is big, basic charge as per installed capacity is higher, and the result still needs many electricity charge.
Summary of the invention
The present invention seeks to provides a kind of apparatus for controlling elevator at the defective that prior art exists.
The present invention adopts following technical scheme for achieving the above object:
Apparatus for controlling elevator of the present invention, it is characterized in that comprising driver module and control module, wherein driver module is composed in series successively by rectifier, filter, inverter, elevator drive system and elevator, and the input termination external ac power source of rectifier is provided with on the elevator by coder; Control module is composed in series successively by voltage detecting circuit, Programmable Logic Controller, driving circuit, the mouth of the input termination elevator drive system of voltage detecting circuit, the input end of the output termination inverter of driving circuit, the mouth of the input end coder of Programmable Logic Controller.
Control system of the present invention is monitored elevator operation in real time, has failure monitoring and self-regulating advantage.
