Further, after elevator enters dormant state, receive calling signal after, can export wake-up signal, be de-energized meeting such as the elevator control cabinet that enters dormant state, sedan-chair top, car, door machine frequency converter, door machine and re-powered, prepare to move.Elevator still can re-power when being called out after entering dormant state, does not influence the passenger and takes.
Further, energy saving system of elevator provided by the invention, circuit pathways switch element are relay, can realize outage and energising effectively, and cost are low.
Further, energy saving system of elevator provided by the invention, circuit pathways switch element are contactless switch, can realize outage and energising in intelligent and high-efficiency ground.
Description of drawings
Fig. 1 is an elevator energy-saving method flow diagram provided by the invention.
Fig. 2 is an energy saving system of elevator scheme drawing provided by the invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, the elevator energy-saving method comprises:
S1, monitoring elevator master control board I/O mouth input/output state;
Elevator master control board monitoring I/O mouth input/output state, if when input/output port does not have input and output in Preset Time, execution in step S2.The default time can be 10～20min, and the present invention does not limit this, and those skilled in the art can set the default time according to actual state.
S2, output sleep signal;
Sleep signal is exported to the circuit pathways switch element before car frequency converter, door machine frequency converter and fan, illumination and the air-conditioning, circuit pathways switch element cut off path, car frequency converter, door machine frequency converter and fan, illumination and air-conditioning, elevator control cabinet and door machine sedan-chair top all can cut off the power supply, and enter dormant state.If elevator in dormant state, has the passenger to take elevator, then execution in step S3.
S3, output wake-up signal.
The output wake-up signal is to receive that the outgoing call button on the elevator outgoing call plate receives passenger's using escalator indication, the floor indication that perhaps car button receives in the car, the elevator master control board is to circuit pathways switch element output wake-up signal, the circuit pathways switch element is opened car frequency converter, door machine frequency converter and fan, illumination and air-conditioning, the circuit pathways on elevator control cabinet and door machine sedan-chair top etc., all parts of elevator are all charged, and elevator prepares to enter into running state.Need to prove, be just to export sleep signal when elevator is in idle condition in Preset Time, and elevator is in dormant state; When elevator was in dormant state, after the elevator master control board was received the calling signal of car button or the transmission of outgoing call button, the elevator master control board just can be exported wake-up signal; The restriction of order before and after step output sleep signal and step output wake-up signal there is no.
