However, in recent years, with the spread of elevators, the management server is required to diagnose and monitor a large number of elevators. Moreover, in recent years, when a failure or tampering occurs in an elevator, remote control or remote recovery of changing the control of the elevator according to a command from the management server is performed. For this reason, the commands transmitted from the management server are spread in various fields, and the number of commands is increasing very much. When all of the elevator response results to these various commands are transmitted to the monitoring center, it is necessary to enlarge the receiving terminal of the monitoring center and increase the number of monitoring personnel.

On the other hand, when the diagnosis operation is executed according to a command from the management server, it is common that there is no abnormality in the diagnosis result. It is sufficient that the diagnosis result without such an abnormality is stored in the management server for the maintenance of the elevator, and the need to receive and confirm it at the monitoring center is low. On the other hand, an elevator failure or abnormal diagnosis result is immediately received and confirmed by the monitoring center, and it is necessary to contact the elevator management company or the like, or dispatch a technician. In this case, if the elevator management company is contacted through the monitoring center, the communication of failure or abnormality may be delayed. In this way, when the only destination of data from the elevator is the monitoring center, unnecessary information may be transmitted to the monitoring center, whereas if necessary information is not transmitted to a necessary place, the transmission and reception of information becomes inefficient and maintenance of the elevator. The quality of the management service may be reduced.

In addition, when the management server diagnoses and monitors multiple elevators, transmission of the diagnosis results from each elevator to the management server may be duplicated. In this case, when the amount of transmission data exceeds the communication capacity of the management server, the data of the diagnosis result cannot be received, and the quality of the maintenance service of the elevator may be deteriorated.

Then, an object of this invention is to improve the quality of the maintenance management service of an elevator.

In the diagnosis of driving performance, the control device 200 moves the car 22 of the elevator 20 shown in FIG. 1 to a predetermined floor, and uses various sensors attached to the elevator 20 for acceleration and abnormal sound. presence or the like is detected. Then, when the acceleration falls within a predetermined range and no abnormal sound is detected, a diagnosis result of OK is input for the driving performance. When the acceleration exceeds a predetermined range or an abnormal sound is confirmed, NG is inputted to the diagnosis result of the driving performance.

In addition, with respect to the brake performance, the control device 200 creates a state where the car 22 of the elevator 20 is full, releases one of the two brakes, and releases the car 22 with the other brake. 22) to diagnose whether it is possible to stop and maintain. And, if the car 22 can be stopped and maintained with only one brake even in a state in which the car 22 is full on both brakes, OK is inputted to the diagnosis result of the brake performance. On the other hand, when one brake alone cannot hold the car 22 stopped, NG is inputted to the diagnosis result of the brake performance. In addition, with respect to door opening and closing, in a state in which the opening and closing driving force of the door 26 is lowered than usual, the doors are opened and closed on each floor, and the door opening and closing time at that time is longer than the door opening and closing time at that time. Diagnose whether or not When opening and closing takes more time than usual, NG is inputted to the diagnosis result of door opening and closing because there is foreign matter. Also, for the emergency power battery, the voltage is checked. If there is no voltage drop, OK is inputted to the diagnosis result of the emergency power battery, and NG is inputted to the diagnosis result when the voltage is falling.

In addition, in each diagnostic item, although there is a fluctuation from the normal numerical value, when the threshold value of abnormal judgment is not reached, A1 is inputted as the presence of modulation in the diagnosis result of each diagnostic item.

When the execution of the diagnostic operation in step S103 of FIG. 6 is finished, the control device 200 proceeds to step S104 of FIG. 6 and outputs the diagnostic operation result data to the monitoring device 250 (refer to FIG. 5). .
