Ratio between the average value of the load in the N number of region received.
6. the detection device that lift car as claimed in claim 5 multiplies load, which is characterized in that described to multiply load condition judgment module
Include:
Load judging unit, for judging that the load total value whether less than the first load threshold value, and judges that the load is total
Whether value is greater than the second load threshold value；Wherein, the first load threshold value is full and logical when maintaining the carriage to multiply manned number
The manned member of multiplying for crossing the N number of region for adjusting the carriage is distributed the load so that when the summation minimum of the load in N number of region
Summation；The second load threshold value is that manned number is full and N number of area by adjusting the carriage when maintaining the carriage to multiply
The manned member of multiplying in domain is distributed the summation so that the load when summation maximum of the load in N number of region；
Load assignment judging unit, for when the load total value is greater than the first load threshold value but is less than second load
When threshold value, judge whether the load assignment of the load in received N number of region meets load assignment condition；If so, determining
The carriage, which is in, normally multiplies load state；If it is not, then determining that the carriage is in abnormal and multiplies load state；
Normally multiply load judging unit, for determining at the carriage when the load total value is less than the first load threshold value
Multiply load state in normal；
Exception multiplies load judging unit, for determining at the carriage when the load total value is greater than the second load threshold value
Multiply load state in exception.
7. the detection device that lift car as claimed in claim 6 multiplies load, which is characterized in that the load assignment condition is specific
Are as follows: it is very poor less than very poor threshold value between the maxima and minima in the load in received N number of region, and received
The mean value of the load in the N number of region arrived is less than average load threshold value；The average load threshold value is when the maintenance carriage multiplies load
Number is full and the manned member that multiplies in N number of region by adjusting the carriage is distributed so that when the load in each region is all the same
Load mean value.
8. the detection device that lift car as claimed in claim 7 multiplies load, which is characterized in that it further include the second notification module,
For:
Multiply load state when the judgement carriage is in abnormal, and the carriage cannot be generated and be in the prompt for multiplying and carrying imbalance
When information, the information warning that the carriage is in overload condition is generated, and notify in such a way that voice reminder or optics are shown
Passenger in the carriage.
