10. an elevator energy-saving energy storage control method based on device described in any one of claim 1-9, it is characterised in that institute
The method of stating comprises the steps:
The first step, acquisition step
By weight-measuring device collection from the analogue signal of representative boarding personage's weight of each floor, it is converted into digital signal；
Gather each floor boarding personage place floor position and the analogue signal in lifting direction by hall buttons, be converted into numeral letter
Number；The raw digital signal of gained is filtered, eliminates interference, it is thus achieved that available digital signal；
Second step, analytical procedure
Calculate the digital signal that obtains of the first step and the balance weight information of call number form, produce the lift car that compares with
The gross weight of boarding personage and balance weight information；
3rd step, judge step
