Claim 11:
12. A method for monitoring an elevator operating environment, comprising the following steps:
A. using a local monitoring device to determine heat index based on temperature data and humidity data of an associated elevator installation or maintenance operating area, and output a first warning message corresponding to the determined heat index locally,
the method also comprises the following steps performed independently of step A:
B1. using the local monitoring devices to transmit the temperature data and humidity data to a cloud computing platform regularly or irregularly;
B2. using the cloud computing platform to generate a corresponding second warning message based on the temperature data and humidity data and send the second warning message to an alarm module so that the alarm module presents the second warning message sent by the cloud computing platform, or send the temperature data and humidity data from the cloud computing platform to the alarm module so that the alarm module generates a corresponding third warning message based on the temperature data and humidity data and presents the generated third warning message.
