Abstract

[0002] During routine maintenance, the capacity of the automatic rescue operation device is confirmed when the car is empty. Since the rated output of the battery cannot be reached, the energy storage capacity of the battery cannot be accurately determined. In particular, after a period of use, the battery ages. Although the rescue operation of the empty car can be completed, when there are passengers in the car, the rescue cannot be completed due to the decline in battery capacity, resulting in passengers being trapped.
[0003] In addition, according to the program setting, according to the load of the car, when automatically rescuing, it runs in the light load direction, that is, when it is empty, the car goes up. Therefore, at this time, the automatic rescue operation device cannot reach the rated output.
[0004] In the prior art, in order to verify the working reliability of the automatic rescue operation device and the energy storage capacity of the battery, the maintenance personnel will confirm the operation of the automatic rescue operation device during maintenance. Usually, the simulation test is carried out under the condition of no-load in the car. However, under no-load conditions, the automatic rescue operation device cannot reach the rated output state, and the energy storage capacity of the battery cannot be accurately judged. In particular, during long-term use, the energy storage capacity of the battery will gradually decrease. The above method cannot accurately check the energy storage capacity of the battery, and there is a certain risk.
[0005] If a power outage occurs when there are many passengers in the elevator, it is easy for the automatic rescue operation to fail to be completed due to the decrease in the battery energy storage capacity, resulting in passengers being trapped. Therefore, we need to propose an energy storage detection system for the elevator automatic rescue operation device. Utility Model Content
