Problems solved by technology

[0004] If the elevator does not have a zero-speed running stage during the start-stop process, the elevator will have disadvantages such as poor start-stop comfort. However, since the elevator can only be in the power generation state when the It will absorb energy from the emergency power supply. If the UPS capacity is insufficient, the elevator control system will not operate normally, and the car will stop at the position when the power was cut off, and passengers in the elevator parked in the non-leveling area will not be released.
The configuration of large-capacity UPS will increase the cost

Embodiment 1

[0071] see figure 2 , an elevator emergency operation control method provided by an embodiment of the present invention, the method can be run in the elevator control system, and is used to control the elevator emergency operation when the elevator control system activates the emergency power supply when the external power supply of the elevator is cut off. The operation control includes step S10 to step S50, which will be described in detail below.

[0072] Step S10: When it is determined that the emergency power supply is activated, obtain the running direction of the elevator in the emergency running state.

[0073] For one possible implementation, see image 3 , when the elevator control system detects that the emergency power supply is activated, step S101 to step S104 are also included, which will be described in detail below.

[0074] Step S101: When it is detected that the emergency power supply is activated, control the elevator to maintain zero-speed running.

Embodiment 2

[0144] see Figure 13 , an elevator emergency operation control device provided in an embodiment of the present invention, comprising:

[0145] The direction acquiring module 10 is configured to acquire the running direction of the elevator in the emergency running state when the emergency power supply is activated.

[0146] The acceleration module 20 is configured to control the elevator to accelerate to a preset emergency running speed according to the running direction.

[0147] The speed stabilization module 30 is used to control the elevator to run at a steady speed according to the preset emergency running speed.

[0148] The deceleration module 40 is configured to control the elevator to decelerate according to a preset deceleration speed when a leveling switch is detected, so that the elevator stops at a corresponding leveling area.

[0149] The zero-speed running module 50 is used to detect that the elevator decelerates to zero speed, and controls the elevator to ma...

Abstract

The invention discloses an elevator emergency operation control method and device. When it is determined that an emergency power source is started, firstly, the operation direction of an elevator under the emergency operation state is obtained, according to the obtained operation direction, an elevator is controlled to be accelerated to the preset emergency operation speed, then, the elevator is controlled to operate at the stable speed according to the preset emergency operation speed, when a leveling switch is detected, the elevator is controlled to be decelerated according to the preset deceleration, the elevator is stopped on a corresponding leveling area, and when it is detected that the elevator is decelerated to the zero speed, the elevator is controlled to maintain zero-speed running until zero-speed running is finished. Under the condition that the elevator is in power failure, the electric capacity of the emergency power source is reduced to be insufficient, through small emergency power source capacity needed by acceleration, speed stabilizing, deceleration and zero-speed operation modes, the elevator can reasonably use the emergency power source capacity, and the emergency operation control scheme is provided for the elevator emergency state.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to an elevator emergency operation control method and device. Background technique [0002] Elevators comprising a car and possibly a counterweight, a drive motor, a control system and an emergency power supply are known and widely used. Such as figure 1 As shown, the elevator car m1 and the counterweight m2 are connected at both ends of the traction machine. During normal operation, the power supply is supplied by the grid, and the direction is determined by the control system. The direction is to go in the direction of the counterweight. At this time, the gravity of the counterweight is greater than that of the car. The elevator controller (absorbing the potential energy of the counterweight) belongs to the power generation operation. When the light load goes down, the car goes down and the counterweight goes up. When the car moves in the direction, the gravity of the counterweig...
