1. for the first mode, when the elevator fails, elevator maintenance personnel can not remotely obtain detailed information of the elevator failure
The fault can only be checked on site, and the fault type is judged after the data is consulted, so that the fault processing time is prolonged, and the influence is caused
The passengers normally take the elevator.
2. For the second mode, the data interfaces of the elevator manufacturers are different and are not opened to the outside, so that the second mode is used as the first mode
Three-party elevator maintenance personnel can not obtain elevator fault information through an elevator communication interface, and still need to go to present
Further inspection and analysis of the field cannot quickly handle the fault.
2. For the third mode, whether the elevator fails or not is judged by additionally arranging the sensor according to the state of the elevator, although a small amount of elevator failure alarm information can be obtained, maintenance personnel are required to go to the site for further checking and analyzing most failures, and the failure processing efficiency is improved to a limited extent.
