The information such as speed and operating range when resistance value, motor efficiency, inverter efficiency when sailing, battery power calculate.Wherein,
The parameter of variation is the load in operating range and lift car.Other specification is fixed, root unrelated with state during power failure
Similarly determined according to the size of car, the species of motor.
For example, in the case of stopping between floor and floor, the distance to nearest floor be present, it is therefore necessary to pass through electricity
Pond driving travels lift car.Therefore, compared with situation about stopping in the state of floor, it is necessary to make motor longer
Period is acted, therefore the consumption of battery is more.Generally, the flat bed operation to nearest floor during power failure is to carry out again
The side of raw operation moves up.
Therefore, in the case that load in lift car is less, car is drawn high by counterweight, and ascent direction turns into regeneration and run
Direction.On the other hand, in the case of being full in lift car, counterweight is drawn high by car, and descent direction turns into regeneration and transported
Capable direction.Run by carrying out above-mentioned regeneration, the electric power required for travelling is less.On the other hand, the load in car
In the case of the degree for reaching car and counterbalancing, pulling force is smaller, therefore power consumption during traveling is more.
In step S505 calculating amount of battery consumption, can based on the load information in above-mentioned car position and car,
Calculate the consumption of correct battery.
Moreover, after computing is carried out using capacity operational part 206, supply determination unit 207 is to all numbers terraced fortune in building
No completion is judged (step S506) at last, in the case where existing without number ladder for completing computing (step S506's is no),
Step S505 is back to, carries out number terraced computing of non-computing.
Moreover, when judging that all numbers terraced computings are completed in step S506 (S506's be), in Battery Diagnostic result OK
Number ladder in, arranged (step S507) according to the less number ladder order of the amount of battery consumption that is calculated in step S505.Moreover,
Determination unit 207 is supplied according to the rank results, determines to provide the battery (step of power supply to Battery Diagnostic result NG number ladder
S508), the instruction for being set to the state after determining is supplied to switching part 208 (step S509).
Specifically, in step S508, send and the minimum number terraced battery of battery consumption is connected to due to Battery Diagnostic knot
Fruit NG and be not carried out nearest floor flat bed operation number terraced instruction, in step S509, by Battery Diagnostic result NG's
Number ladder goes to the flat bed operation of nearest floor.
Thus, when the battery of power failure deteriorates, judge most there is the battery of surplus energy in battery capacity, carry out to other
The supply of number terraced power supply.Thus, the flat bed for nearest floor being gone to using the battery of power failure is run, and can prevent can not
State of the flat bed to nearest floor.In this case, the computing of the amount of battery consumption in step S505 can be after having a power failure
Carry out immediately, each ladder can be immediately performed the flat bed operation of nearest floor, and be accomplished to nearest building without waiting for other number ladder
The flat bed operation of layer.
In addition, for example can also be judged as only with 1 battery it is inadequate in the case of, examined simultaneously to battery from multiple batteries
A disconnected result NG number ladder provides power supply, is used as the battery that power supply is provided in step S508.
