In order to avoid the stopping of unnecessary lift appliance caused by vibration excessive caused by this passenger, this embodiment party
One of the function of lift appliance as electric safety control-ler 200 involved by formula and there is low-pass filter processing unit 203.It should
Low-pass filter processing unit 203 can also be frequency caused by the excessive vibration for blocking the speed signal of lifting body 103 to be included
The low-pass filter of rate component.Also, by low-pass filter processing unit 203, the speed signal of lifting body 103 is blocked
Frequency component caused by excessive vibration is filtered, thus, it is possible to avoid passenger caused by need not caused by excessive vibration
The stopping for the lift appliance wanted.
Herein, it may be said that in vibration excessive caused by being applied with passenger, lifting body 103 is to include that main rope 105 etc. is restricted
The eigentone of lifting body 103 including system is rocked.Therefore, low-pass filter (low-pass filter processing unit 203)
Blocking characteristics include that the eigentone of the lifting body 103 including rope system is critically important.But the position of lifting body 103
The length (for example, being the length until hoist engine 106 in the configuration example 1 of Fig. 1) for setting different and main rope 105 changes, therefore
The eigentone of lifting body 103 also changes because of the position of lifting body 103.
Accordingly, with respect to the eigentone of the lifting body 103 of the blocking characteristics suitable for low-pass filter, it is expected that by it
Minimum value is set as the blocking characteristics of low-pass filter.The minimum value of the eigentone of lifting body 103 is the length of main rope 105
Eigentone, lifting body 103 when spending longest are located at intrinsic when travelling bottom (for example, lowest level) in stroke
Vibration frequency.

Here, being connected to the weight of the rope system of lifting body 103, length, rigidity, radical, thimble rod (Thimble rod)
It is the quality for the maximum bearing capacity for including lifting body 103 Deng synthesis spring constant, m.Number of the quality of lifting body 103 because of passenger
Deng and it is different, therefore be set as include maximum bearing capacity quality.
Fig. 6 is the example of the performance plot for the frequency characteristic (blocking characteristics) for indicating low-pass filter.Above-mentioned calculating will be utilized
The eigentone fn of the calculated lifting body of formula (1) 103 is set as the cutoff frequency of the frequency characteristic of low-pass filter, from
And it reliably blocks excessive vibration caused by passenger and includes the frequency of (carrying) in the speed signal of lifting body 103
Component.Thereby, it is possible to reliably avoid the stopping of unnecessary lift appliance caused by vibration excessive caused by passenger.
It is utilized in the function other than switching function of overrunning from speed in addition, electric safety control-ler 200 is used
The structure of the speed signal for the lifting body 103 that information calculating part 202 exports.Specifically, the speed signal of lifting body 103 in addition to
It overruns and is also used in terminating layer forced deceleration function part 206 other than switching function portion 207.Here, low-pass filter (low pass filtered
Wave device processing unit 203) place only is filtered to the speed signal used in switching function of overrunning (overrun switching function portion 207)
It manages critically important.
Specifically, using with lower structure, i.e., only to being input to the switching function portion that overruns from velocity information calculating part 202
207 speed signal is filtered, and is directly believed using the speed exported from velocity information calculating part 202 other function parts
Number waveform.In the case of this example, it is strong that the function part other than the switching function portion 207 that overruns of operating speed signal becomes terminating layer
Deceleration portion 206 processed.The position exported from positional information calculation portion 201 is inputted to terminating layer forced deceleration function part 206 to believe
Number and from velocity information calculating part 202 export speed signal.
If here, being filtered to the speed signal inputted from velocity information calculating part 202, speed signal can produce
Raw delay.As a result, in the position signal and speed signal for needing to be input to terminating layer forced deceleration function part 206 in identical timing
Between, deviation can be generated in incoming timing, therefore the processing of terminating layer forced deceleration function part 206 will appear exception.From this
Any sets out, and is only filtered to the speed signal used in switching function of overrunning (overrun switching function portion 207), is right
Speed signal for other functions is critically important without being filtered.
In addition, the present invention is not limited to above-mentioned embodiment, including various modifications example.For example, above-mentioned embodiment
The detailed description for being to facilitate the understanding of the present invention and carrying out, however it is not limited to have to have all compositions.
