Embodiment 1

[0035] see figure 1The schematic diagram of the overall structure of the cooperative control device of the elevator driving motor and the brake of the present invention is shown. The cooperative control device of the elevator driving motor and the brake of the present invention includes: a driving motor that provides driving torque for the elevator car to rise and fall in the hoistway; The car lifts and lowers in the hoistway to provide braking torque and the brake torque can be controlled, and the total torque of the total torque command is generated according to the speed command of the driving motor or the car and the actual speed of the driving motor or car a command generation unit, which distributes the total torque command generated by the total torque command generation unit and generates the total torque command distribution unit of the drive motor torque command and the brake braking torque command, according to the total torque command distribution unit The generate...

Embodiment 2

[0050] see figure 2 Shown is a schematic diagram of the overall structure of an elevator that uses a cooperative control device for an elevator drive motor and a brake in the present invention. It can be seen that the elevator includes a weighing unit for determining the load of the elevator car, and a weighing unit for determining the next stop floor of the elevator car. The next stop determination unit, the speed instruction generation unit for generating the elevator car to run from the current position to the next stop floor of the elevator car determined by the next stop determination unit, and the elevator drive motor and brake in Embodiment 1 cooperative control device. The next stop floor signal of the elevator car output by the next stop determination unit and the elevator car load signal output by the weighing unit are sent to the speed command generation unit as input signals, and the speed command generation unit is based on the input signal of the next stop of th...

Embodiment 3

[0053] see image 3 Shown is a schematic diagram of the overall structure of another elevator that uses the cooperative control device of the elevator drive motor and brake in the present invention. It can be seen that the elevator includes a speed command generation unit for generating the speed command of the elevator car, and the elevator in Embodiment 1 The coordinated control device of the driving motor and the brake and the limit limiting torque determined by comparing the braking torque with the maximum torque that can be generated by the driving motor and the maximum braking torque that can be generated by the brake determine the car Acceleration limiting unit whether the acceleration reaches the limit limiting torque. The speed command signal output by the speed command generating unit and the acceleration limit value output by the acceleration limiting unit are sent to the cooperative control device of the elevator drive motor and brake as input signals, and the coop...

Abstract

The invention discloses an elevator driving motor and brake cooperative control device which comprises a driving motor, a brake, a total torque instruction generation unit, a total torque instruction distribution unit, a driving motor controller and a brake controller. The total torque instruction distribution unit distributes total or partial total torque instructions to the driving motor to serve as torque instructions of the driving motor, and when the total torque instruction distribution unit distributes partial total torque instructions to the driving motor to serve as torque instructions of the driving motor, the other total torque instructions serve as brake torque instructions of the brake. The elevator driving motor and brake cooperative control device can improve the elevator passenger capacity and shorten elevator car moving time by increasing the elevator car load and improving the elevator maximum speed and / or maximum acceleration, and accordingly effectively improves the elevator transporting efficiency, reduces the number of people waiting for the elevator in the passenger flow peak period, shortens the elevator waiting time of passengers and relieves the crowded condition of an elevator hall. The invention further discloses an elevator provided with the elevator driving motor and brake cooperative control device.

Description

technical field [0001] The invention relates to an elevator control device, in particular to a coordinated control device for an elevator driving motor and a brake. The invention also relates to an elevator using the cooperative control device. Background technique [0002] The setting of the electrical capacity of the elevator drive system is usually based on the rated speed and / or acceleration to move the elevator car with the rated load, so the required driving speed of the traction elevator can be used when it is not fully loaded or not empty. The characteristic that the torque is less than the maximum torque that its drive unit (usually the electric capacity of the elevator drive unit) can provide, shorten the running time of the elevator by increasing the speed and / or acceleration of the elevator, so as to realize the improvement of the driving efficiency of the elevator Improve, be referred to as variable-speed elevator technology, as Chinese invention patent applica...
