摘要:
An elevator control cabinet used in an elevator system includes a voice communication apparatus having a microphone, an electronic control arrangement, an evaluation unit, and a cabinet housing having at least one cabinet door. The voice communication apparatus is used to execute a service or emergency call or establish a communication between the elevator and a public communication network. The microphone detects a surrounding noise in the control cabinet. The evaluation unit converts the detected noise into a noise pattern and then compares this noise pattern with a reference sound pattern that is predetermined for a surrounding noise in the cabinet housing with the open or closed cabinet door. This reference sound pattern is saved in a storage unit of the control arrangement. In dependence on a result of the comparison, the evaluation unit will recognize whether the cabinet door is open or closed.
