specific Embodiment approach

[0035] Assuming the floor height is five floors, figure 1 It is a schematic diagram of the elevator running action points. There are seven main action points: limit point (1), limit point (2), leveling point (3), speed change point (up) (4), forced speed change point (5) ), layer change point (6), speed change point (down) (7).

[0036] figure 2 It is the structural diagram of the over-rated elevator speed controller according to the present invention, the speed mode selection module (8) receives the car weight information, the leveling signal receiving module (9) receives the leveling signal, and the speed change point signal receiving module (10) Receiving the speed change point signal, the accident signal receiving module (11) receives the forced speed change point signal, the limit point signal and the limit point signal, and the signals received by the modules (8), (9), (10), and (11) It is sent to the signal processing module (12), and after event judgment and process...

Embodiment 1

[0039] Such as figure 1 , figure 2 As shown, taking the elevator going up from the first floor to the fifth floor (destination floor N=5) as an example, the details are as follows:

[0040] The speed mode selection module (8) outputs speed mode information according to the weight information detected by the car weighing unit; when it is detected that the elevator loading weight is between 30%-70% of the rated loading weight, the elevator selects the over-rated speed mode to run , in other cases, select the rated speed mode to run.

[0041] 1. If it is an over-rated operation mode, the signal processing module (12) outputs a speed control signal, and the elevator accelerates from the first floor to the over-rated speed (1.2 times the rated speed) to run at a constant speed. The elevator does not make any response at the action point, and keeps running at a constant speed exceeding the rated speed; when running to the fourth floor (up to N-1=4) leveling point (3), the signal ...

Embodiment 2

[0044] Such as figure 1 , figure 2 As shown, taking the elevator going down from the fifth floor to the first floor (destination floor N=1) as an example, the detailed description is as follows:

[0045] Limit point (1), limit point (2), leveling point (3), speed change point (up) (4), forced speed change point (5), layer change point (6), speed change point (down ) (7).

[0046] The speed mode selection module (8) selects an output speed mode according to the weight information detected by the car weighing unit;

[0047] 1. If it is in the over-rated operation mode, the signal processing module (12) outputs the speed control signal, and the elevator accelerates from the fifth floor to the over-rated speed (1.2 times the rated speed) and runs at a constant speed. The elevator at the action point does not make any response, and keeps running at an over-rated speed at a constant speed; when running to the leveling point (3) on the second floor, the leveling point signal rece...

Abstract

The invention discloses an elevator speed controller for rated-speed-exceeding running and a control method of the controller. The elevator speed controller comprises a speed mode selecting module (which is used for selecting whether an elevator runs at a speed exceeding a rated speed according to weight information of an elevator car), a flat floor signal receiving module (which is used for providing reference signals for speed change for the first time while the elevator runs at the speed exceeding the rated speed), a speed change point signal receiving module, an accident signal receiving module and a signal processing module (which is used for receiving output signals of the modules, carrying out accident response and processing in combination of an objective floor and running direction of the elevator and transmitting speed control signals). The elevator speed controller does not need to be additionally provided with other hardware devices or change original hardware structure facilities, and the height of a top hoistway floor and the depth of a bottom pit do not need to be enhanced, but only by designing software and carrying out auxiliary speed change on the rated-speed-exceeding running of the elevator by virtue of flat floor points of the elevator, the running of the elevator at the speed exceeding the rated speed can be realized, and the elevator can run at an efficient, energy-saving and safe manner. Meanwhile, the elevator speed controller can meet the requirements on new elevator installation and old elevation transformation, and is beneficial to technique popularization.

Description

technical field [0001] The invention belongs to the technical field of elevator driving and energy saving, and in particular relates to a speed controller of an elevator with an overrated speed. Background technique [0002] According to the recent statistics and predictions of the national special equipment competent department, as of 2010, the number of elevators in my country has reached more than 2 million units, which is the country with the most elevators. In 2011, the country produced more than 400,000 elevators, ranking first in the world; in recent years, the average annual growth rate of elevators in my country has exceeded 22%, and my country has become the world's largest elevator market, the world's largest elevator manufacturing base, and the world's largest elevator export country. With the rapid growth of the number of newly installed elevators, the huge energy consumption of elevators has attracted the attention of governments and relevant organizations of v...
