Maintenance monitoring system
First Claim
1. A maintenance monitoring system for a plurality of independent unrelated distinguished installations where each installation may comprise one or more devices requiring maintenance at which individually after expiration of maintenance time intervals different types of maintenance work must be performed, comprising:
- a monitoring maintenance device arranged at every installation, each maintenance device including means responsive to operation of an associated installation to measure the elapsed time the installation is operating, means responsive to said means to measure for registering predetermined maintenance relevant operation time intervals of the associated installation and means responsive to expiration of maintenance time intervals for emitting a respective signal specific to each predetermined maintenance time interval to an associated output, andthe outputs of the maintenance monitoring devices being led through a common link to a central evaluation unit for evaluating the output signals of the maintenance monitoring devices, said unit including means for displaying an overview of the state of the maintenance of all installations.

Abstract
In order to oversee and plan, at overall shop level, the execution of maintenance work on several installations (1), each having monitoring equipment (3) which monitors the intervals at which maintenance should be carried out on the installations, it is proposed that the outputs (A3) from the monitoring equipment (3) be fed to a processing unit (27) which produces maintenance status reports (53) for the whole shop. Registers, which store certain maintenance intervals, are reset only upon recognition of maintenance personnel at the site of the installation by manual input and recognition of the condition at the processing unit by a remote input.

15. A maintenance monitoring system for a plurality of unrelated installations of various different types, individually put into operation independently of one another, comprising:
-
each installation (1) having a monitoring maintenance device (3), each monitoring maintenance device including; means (29) for acknowledging maintenance operations performed at the associated installation, means (9) responsive to operation of an installation for measuring the time span the associated installation has been in operation, means (13) responsive to said means (9) for measuring and to said means for acknowledging (29) and monitoring predetermined maintenance time intervals departing from respective acknowledgements of maintenance operations performed by said means for acknowledging and for emitting signals indicative of said monitored maintenance time intervals, said maintenance monitoring system further comprising; a central evaluation unit (27); means at each installation for coupling said signals of each of said means for monitoring maintenance time intervals to said central evaluation unit; and said central evaluation unit including means (53) for displaying an overview of the state of said monitored maintenance time intervals of all said installations (1). - View Dependent Claims (16, 17)
