Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] An embodiment of the present invention is a method for setting the running speed of an elevator, which includes the following steps.

[0021] Step 1: When the elevator gives the running direction, according to the distance S between the current floor and the previous floor 1 automatically calculates a velocity V 1 , however it is generally difficult to directly 1 Calculate V with the above known quantities 1, the unit is m / s. The previous floor in front is the next floor that the elevator will reach. That is to say, it is difficult to directly base on S 1 and known quantities are calculated to obtain an accurate usable V 1 . The target floor is the floor where the elevator will stop next time.

[0022] For example, determine the distance S between the current floor and the first floor the elevator will reach 1 , the distance S...

Abstract

The invention discloses an elevator, and a method and a device for setting operating speed of the elevator. The method includes following steps: A1, when giving an operating direction of the elevator, determining distance Sn between a current floor and each floor when the elevator is about to reach; A21, setting an operating speed Vn of the distance Sn to be an initial speed V0; A22, calculating a reference distance S according to the operating Vn and an S curve; A23, when S<Sn, adjusting the operating speed Vn to be Vn+an adjusting speed Vdelta, continuing to execute A22 until S>Sn, and acquiring an optimal operating speed Vn-best to be Vn-Vdelta; when S>Sn, adjusting the operating speed Vn to be Vn-Vdelta, continuing to execute A22 until S<Sn, and acquiring the optimal operating speed Vn-best to be Vn; and A3, controlling the elevator to adopt Vn-best to travel the distance Sn.

Description

technical field [0001] The present invention relates to an elevator, in particular to an elevator and a method and device for setting its running speed. Background technique [0002] When the elevator is running at the rated speed and rated load, the corresponding output of the traction machine is generally the rated voltage of the traction machine. At present, elevators are basically frequency-controlled. In the past two years, elevator integrated controllers have been widely used. The maximum output voltage of the elevator integrated controller is closely related to the input voltage. When the input voltage is too low, if the elevator is at the rated load and rated speed, the motor current waveform will be distorted, the motor noise will increase, the elevator will shake, and the motor will Disadvantages such as deviation between the actual running speed and the given speed. For this reason, it is necessary to decelerate the actual running speed of the elevator. [0003...
