Remote monitoring technology is utilized for improvement of maintenance for elevators quality and rationalization of work. In this article we will introduce examples of its use and the latest technology. Remote monitoring technology is the most important technique for preventive maintenance of elevators. Inspection contents of machine room-less elevator are seven items such as instruments in the major item and 192 items in the segmented inspection contents. Many remote inspection functions corresponding to these inspection items have been developed. This article introduces two examples. One is an example of door diagnosis, and the second is an example of electromagnetic brake diagnosis. Furthermore, operation measurement data is used for setting the optimum parts replacement cycle and maintenance cycle. Optimization of main rope replacement cycle will be explained as an example of utilization of operation measurement data. As a function other than preventive maintenance, there is a remote rescue function that provides early rescue when passengers are trapped inside the elevator car. Also, it is utilized to prevent damage and to improve the efficiency of restoration work at the time of earthquake. Furthermore, in order to improve the convenience of users, it is used for changing some operation control settings. And, it is also used for information setting of a display device in a car.
