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
The information obtaining second step carries out size of data and compares, and i.e. compares the gross weight of lift car and boarding personage and calls The size of the balance weight information of digital form, show that this personage's boarding is the numeral letter of zero load, underloading, semi-load or heavy duty Breath;
4th step, output step
The effectiveness of the digital information that the 3rd step obtains is estimated, exports control instruction, by controlling the outfan of device Mouth, respectively to each execution device, determines that starting which set performs device, thus realizes energy-conservation effect.
