1. A system for monitoring an elevator operating environment, comprising at least one local monitoring device, a cloud computing platform, and at least one alarm module associated with the local monitoring device,
wherein, each of the local monitoring devices is arranged in an associated elevator installation or maintenance operating area and is configured to:
determine heat index based on temperature data and humidity data of the associated elevator installation or maintenance operating area, and output a first warning message corresponding to the determined heat index locally; and
transmit the temperature data and humidity data to the cloud computing platform regularly or irregularly,
wherein, the cloud computing platform is configured to send the temperature data and humidity data to the alarm module regularly or irregularly, and the alarm module is configured to generate a corresponding third warning message based on the temperature data and humidity data and present the generated third warning message; or
the cloud computing platform is configured to generate a corresponding second warning message based on the temperature data and humidity data and send the second warning message to the alarm module, and the alarm module is configured to present the second warning message sent from the cloud computing platform.
