Problems solved by technology
[0003] Inverters that are very sensitive to transient voltage disturbances such as voltage sags are often used in vertical elevator systems. Short-term voltage drops or voltage sags of the power supply often cause vertical elevators to get stuck midway, suddenly fall, and other hazards that endanger personal safety. Fault, there is a disadvantage of low safety in use
Elevator users are often unaware of the danger

Embodiment Construction
[0024] A simulation system for elevators affected by voltage sags, such as figure 1 As shown, it includes a control terminal 110, a power supply device 120, an uninterruptible power supply device 130, an elevator control device 140, an elevator simulation device 150, and a waveform monitoring device 160. The control terminal 110 is connected to the power supply device 120 and the uninterruptible power supply device 130. The elevator control device 140 is connected to power supply device 120 , uninterruptible power supply device 130 and elevator simulation device 150 , and waveform monitoring device 160 is connected to power supply device 120 and elevator control device 140 .
[0025] The control terminal 110 is used to send a voltage sag command to the power supply device 120 , and send a management equipment input command to the uninterruptible power supply device 130 . The control terminal 110 may specifically be a device such as a keyboard, a button, or a touch screen. The...

The invention relates to a simulation system and a simulation method for an elevator affected by a voltage sag, including a control terminal, a power supply device, an uninterruptible power supply device, an elevator control device, an elevator simulation device and a waveform monitoring device. The control terminal is connected to the power supply device and the uninterruptible power supply device The power supply device, the elevator control device is connected to the power supply device, the uninterruptible power supply device and the elevator simulation device, and the waveform monitoring device is connected to the power supply device and the elevator control device. By demonstrating the impact of voltage sags on elevators and the countermeasures, users' awareness of voltage sags can be improved, and users can be guided to recognize the mechanism and coping strategies of voltage sags on elevators, improving the safety of elevators.
Description
technical field [0001] The invention relates to the technical field of elevator control, in particular to a simulation system and a simulation method for elevators affected by voltage sags. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. Elevators have the advantages of low energy consumption, energy saving and high efficiency, and fast lifting speed, and they occupy an increasingly important position in people's daily work and life. [0003] Inverters that are very sensitive to transient voltage disturbances such as voltage sags are often used in vertical elevator systems. Short-term voltage drops or voltage sags of the power supply often cause vertical elevators to get stuck midway, suddenly fall, and other hazards that endanger personal safety. There is a shortcoming of low safety in use. Elevator users are often unaw...
