The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail:
Embodiment 1
A kind of elevator intelligent power-saving method of the present invention, the method comprises: according to disconnection work-hours, intelligent decision and the control technology set, and by detecting the variation of elevator main circuit current or power circuit power, judge that whether elevator is in readiness for action; , trigger actuating unit and cut off elevator main circuit current in readiness for action and extend after certain hour at elevator, realize elevator intelligence in the time of readiness for action and cut off the function of power supply.Above-mentioned intelligent decision and control technology are in the time arriving the disconnection work-hours of setting elevator, according to the threshold value of setting, compare with the current value or the magnitude of power that detect, the relatively detected value in sense cycle and the size of threshold value, and automatically judge that whether elevator is in readiness for action, output signal drives actuating unit.
Technique scheme specifically comprises the following steps as shown in Figure 1:
In sense cycle, whether be less than or equal to the threshold value of sign state according to all detected values, if be less than or equal to after this threshold value, for guaranteeing the safe and reliable of elevator work, judge that more whether elevator is in readiness for action, if elevator is in readiness for action, time delay also keeps the continuous detecting some time.
If in time delay and keep the detected value in the continuous detecting some time to be still less than or equal to threshold value, judge that whether elevator is in unmanned use state, if in unmanned use state, perform step step 105.
Step 105 is cut off elevator main circuit current, realizes elevator intelligence in the time of long-term readiness for action and cuts off the function of power supply;
Above-mentionedly send signal by intelligent decision and control module, trigger actuator module and cut off elevator main circuit current.
When step 106 reaches the reset work-hours of setting, recover elevator power circuit closure;
Send signal by intelligent decision and control module, trigger actuator module and recover elevator power circuit closure.
Said method lost efficacy in order to prevent elevator intelligent economize on electricity; first be the accuracy that guarantees timer counter with plesichronous counting machine; next is, in intelligent decision and control module, security protection module is set; in order to detect actuating unit contact on off mode; compare current status simultaneously; if judge that Intelligent electricity-saving device for elevator lost efficacy, cancel the intelligence of intelligent decision and control module and cut off the function of power supply.Meanwhile, for convenient operation, condition selecting module is set in human-computer interaction module, in the time not needing intelligent energy-saving function, can cancels the intelligence of intelligent electric-saving device by this switch and cut off the function of elevator power supply.
