In embodiment, predetermined policy can be the corresponding relation between rope speed and target frequency, goes out rope speed the fastest then target frequency
Rate is the highest,
In step 1105, the vibroswitch activated in the control crank of elevator initiates vibration with feedback according to target frequency
Elevator go out rope speed.
The rope speed that goes out of elevator can be fed back to user by operation handle by the method, and user is utilizing operation handle control
Can immediately know while lifting-speed processed and go out rope speed in real time, in order to be adjusted correspondingly, e.g., in the feelings that vibration is strong
Under condition, user learns rope stretching excessive velocities, it is possible to utilizes in time operation handle to slow down lifting-speed, thus avoids sending out of danger
Raw；In the case of vibration is faint, user learns out that rope speed is slow, and handle can be utilized the most in time to improve elevator speed
Degree, thus improve work efficiency.
The flow chart of one embodiment of the lifting-speed control method of the present invention is as shown in figure 12.
In step 1201, by coaxially connected with elevator, and the elevator encoder of rotation counting under the drive of elevator
Obtain count value.
In step 1202, determine the rotating cycle of elevator according to count value.
In step 1203, steel wire rope coiling parameter based on elevator, detect according to the rotating cycle of elevator with last time
Between time interval, determine elevator goes out rope speed.
In step 1204, rope speed is gone out, as utilized display screen to demonstrate rope speed etc. to user feedback elevator.
The method can obtain the rotating cycle of elevator by elevator encoder, so calculate elevator go out rope speed,
Owing to elevator encoder accuracy is higher, therefore, it is possible to accurately gone out rope speed；Improvement for bindiny mechanism is little, has
It is beneficial to practical application；Can adjust in real time according to feedback result to the rope speed that goes out of user feedback elevator, user, anti-
The only generation of security incident.
The flow chart of another embodiment of the lifting-speed control method of the present invention is as shown in figure 13.
In step 1301, determine elevator goes out rope speed.Elevator can be determined by the either method being mentioned above
Go out rope speed.
In step 1302, determine the target frequency of correspondence based on predetermined policy according to the rope speed that goes out of elevator.
In step 1303, activate the vibroswitch being positioned at operation handle and initiate vibration to feed back volume according to target frequency
That raises goes out rope speed.
The rope speed that goes out of elevator can be fed back to user, Yong Hu by operation handle by the way of vibration by the method
Utilize operation handle can immediately know while controlling lifting-speed and go out rope speed in real time, in order to be adjusted correspondingly, e.g.,
In the case of vibration is strong, user learns rope stretching excessive velocities, it is possible to utilize operation handle to slow down lifting-speed in time, thus
Avoid the generation of danger；In the case of vibration is faint, user learns out that rope speed is slow, can utilize hands the most in time
Handle improves lifting-speed, thus improves work efficiency.
Finally should be noted that: above example is only in order to illustrate that technical scheme is not intended to limit；To the greatest extent
The present invention has been described in detail by pipe with reference to preferred embodiment, and those of ordinary skill in the field are it is understood that still
The detailed description of the invention of the present invention can be modified or portion of techniques feature is carried out equivalent；Without deviating from this
The spirit of bright technical scheme, it all should be contained in the middle of the technical scheme scope that the present invention is claimed.
