1. an elevator intelligent power-saving method, is characterized in that, described method specifically comprises the following steps:

  • Step 101 is set and is disconnected work-hours and reset work-hours, in the time arriving the disconnection work-hours of setting, continuously elevator main circuit current or power is detected in sense cycle by main detection module, obtains single-phase detected value and three-phase average;

    Step 102 is by single-phase detected value and three-phase average and the threshold that characterizes readiness for action;

    Step 103 judges that whether elevator is in readiness for action;

    In sense cycle, whether be less than or equal to the threshold value that characterizes readiness for action 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;

    Step 104 judges that whether elevator is in unmanned use state;

    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 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.
