Abstract An elevator monitor apparatus comprises an elevator control device for controlling the driving of an elevator, an individual control device for controlling the status of elevators building by building, a central monitor device for centrally monitoring the status of the elevator in a plurality of buildings. There is also provided a job start signal generation device for generating a job starting signal when an elevator maintenance and check-up job is started, a job completion signal generation device for generating a job completion signal when an elevator maintenance and check-up job is finished, and a communication control device for communicating with the elevator control device according to an instruction from the individual control device and for outputting an abnormality signal to the central monitor device when a job completion signal from the job completion signal generation device is not detected before a predetermined time has elapsed.
An elevator monitor apparatus, comprising: elevator control means for controlling the driving of an elevator; individual control means for controlling the status of elevators building by building; central monitor means for centrally monitoring the status of the elevators in a plurality of buildings; job start signal generation means for generating a job starting signal when an elevator maintenance and check-up job is started; job completion signal generation means for generating a job completion signal when a elevator maintenance and check-up job is finished; communication control means for communicating with said elevator control means according to an instruction from said individual control means, said communication control means sounding an alarm after a first predetermined time period has elapsed following detection of a job starting signal from said job start signal generating means, said communication control means outputting an abnormality signal to said central monitor means when a job completion signal from said job completion signal generation means is not detected after a second predetermined time period has elapsed following the sounding of the alarm.
