It is located at traction host when sustained height according to carriage and counterweight in the carriage downlink operational process that load is the first weight
Export electric current I1' and load be traction when carriage and counterweight are located at sustained height in the carriage downlink operational process of the second weight
Host exports electric current I2' draw the second load current curve；
According to the intersection point calculation balance coefficient of elevator K of first curve of load and second curve of load.
10. balance coefficient of elevator detection method according to claim 6, which is characterized in that the detection method further include:
S7 calculates balance coefficient of elevator according to rated load Q and current balance coefficient of elevator K and adjusts to K0When increase or decrease
Counterweight mass；
And/or in step s 5, " screening valid data according to judging result " includes:
When the judgment result is yes, carriage runs from bottom to top layer uplink or is adopted from top layer into bottom downlink operational process
It is effective to collect data；When the judgment result is no, carriage runs from bottom to top layer uplink or ran from top layer to bottom downlink
Acquired data invalid in journey.
