Description
Technical field：
The present invention relates to elevator technology field, more particularly to a kind of elevator starts the implementation method of compensation.
Technical background：
Comfort when to ensure that elevator starts calculates one generally before elevator startup according to the load condition in compartment
Torque value starts offset, is exported before elevator opens band-type brake to the motor of traction machine, after band-type brake opening, startup compensation
Value can decrease or even eliminate the amount of unbalance of elevator cage and counterweight, and then be reduced or avoided when elevator starts and fly out or invert now
As.
The common computational methods for starting offset are generally：The startup offset of setting one at light load, sets a weight
Start offset when load, that is, starts a reference value of compensation.The load value that elevator claims before starting according to weighing sensor, in proportion
Calculate this startup offset.
But the value of weighing of weighing sensor is understood passage at any time and is changed, and there is a phenomenon where value inaccuracy of weighing, especially
It is mounted in the weighing sensor of cage bottom.It naturally can not accurate balancing vehicle with the startup offset of inaccurate value calculating of weighing
The amount of unbalance in compartment and counterweight causes the startup of elevator over time to fly out often or reversal development, the comfort of startup
It is deteriorated.
On the other hand, starting offset often all needs live setting, and majority is to be manually set, and starts setting for offset
It is fixed nor very precisely, with the inaccurate calculated driving offset of a reference value can not good balanced carriage and counterweight not
Aequum.
In another aspect, some owners are after elevator is delivered for use, voluntarily change the decoration of elevator cage, leads to compartment and right
The amount of unbalance offset of weight, does not often reset because starting compensation at this time, and it is not accurate to also result in startup compensation calculation value.
Industry has using high-precision encoder in recent years, when elevator opens band-type brake according to velocity feedback, quickly adjusts and turns
Square, the amount of unbalance to eliminate compartment and counterweight exempt from Weighing control method, although this method improves the essence for starting offset
Accuracy improves comfort level when startup, but the more traditional volume of cost of the decoding circuit of high-precision encoder and the encoder
High more of code device.
Invention content：
Technical problem to be solved by the present invention lies in for present in the common computational methods of existing startup offset
Insufficient and provide the implementation method that a kind of elevator starts compensation, elevator speed when being started by detecting starts compensation to identify
Effect automatically updated with the compensation torque value that the current load-carrying of system and the load-carrying are actually needed when starting compensating cariation
The a reference value for starting compensation allows subsequent startup compensation calculation value closer to actual demand.
The technical problems to be solved by the invention can be achieved through the following technical solutions：
The implementation method that a kind of elevator starts compensation detects the feedback speed of elevator before elevator starts to elevator traveling,
When feedback speed be more than threshold values and elevator speed be zero and band-type brake open when, record load value at this time and torque value, and
Start standard of compensation value with load value at this time and the torque value update recorded is former, realizes the automatic calibration for starting compensation.
It refers to main contactor actuation that in a preferred embodiment of the invention, the elevator, which starts, starts compensation exports,
A kind of mode or arbitrary two or more mode in band-type brake opening combine.
In a preferred embodiment of the invention, the elevator traveling refers to that elevator starts to move according to non-zero speed instruction
It is dynamic.
In a preferred embodiment of the invention, the state when elevator speed is zero and band-type brake is opened refers to
Start the zero-speed before traveling or obtains zero-speed state and specially start an elevator.
As a result of technical solution as above, when the implementation method that elevator of the invention starts compensation is started by detecting
Elevator speed come identify start compensation effect, when starting compensating cariation, with the current load-carrying of system and the load-carrying reality
The compensation torque value needed automatically updates a reference value for starting compensation, and subsequent startup compensation calculation value is allowed to be needed closer to practical
It asks, has the advantages that compensation effect is good and at low cost.
