Equipment management system that issues a warning when the lifetime of a component has been exceeded and disables the warning when such a warning is to be generated for a different component
First Claim
1. An equipment management system comprising a communications control device that is attached to a managed piece of equipment so as to transmit equipment management data with which the piece of equipment is managed, and a host computer that is connected to said communications control device through a communications network so as to collectively manage data received from the communications control device,wherein said communications control device is provided with a component lifetime management means having a plurality of count fields allocated to a plurality of components of said managed piece of equipment said component lifetime management means storing count values representing how many times the components have been involved in processing in the count fields, respectively, and clearing the count value in a count field when the component to which the count field is allocated is replaced, said component lifetime management means further having transmitting means for transmitting the count values in the count fields to said host computer at predetermined times,and wherein said host computer is provided with a warning means which, for every component, compares a count value received from said communications control device with a threshold value and which, when there exists a component whose threshold value is exceeded recognizes necessity of component replacement and issues a component replacement warning, and said host commuter is further provided with a warning disabling means which disables issuance of a component replacement warning if, during a period after issuance of a component replacement warning for one component and before replacement of the component targeted by the warning, another component becomes a target of a component replacement warning.

Abstract
In a system in which a host computer performs lifetime management for components of a plurality of copiers, components whose lifetimes are to be managed can be freely selected copier by copier and, as a result, warning reports can be transmitted with a reduced number of communication sessions. The copiers are each equipped with a device for management, so that counting can be performed for their individual components and interlock counts for such counting can be freely specified. The host computer compares a count received through communication with a threshold value to issue a report within the host computer. Within one copier, during a period after a component PM call is issued and before a component is replaced, even if another component becomes a target of a component PM call, the component PM call is not issued. When a component replacement report is received, a report of a component PM call is automatically deleted from an urgency report list. A component whose component PM call has been exceeded is indicated with a mark requesting replacement.

7. An equipment management system comprising:
-
a communications control device for transmitting equipment management data corresponding to a managed piece of equipment; and a host computer for collectively managing data received from the communications control device, said host computer communicating with said communications control device via a communications network, wherein said communications control device includes component lifetime managing means for storing count values in a count field representing the number of times a component of said managed piece of equipment has been involved in processing, and transmitting means for transmitting count values stored in said count field to said host computer via said communications network at predetermined times, said host computer includes warning means for issuing a component replacement warning, said warning means comparing a transmitted count value received from said communications control device with a threshold value stored by said host computer and issuing a component replacement warning when said transmitted count value exceeds said threshold value, and said host computer further includes warning disabling means for disabling issuance of a component replacement warning if, during a period after issuance of a component replacement warning for one component and before equipment of said one component, another component becomes a target of a component replacement warning. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. An equipment managing method for managing a piece of equipment with a communications control device and a host computer communicating with said communications control device via a communications network, said method comprising:
-
incrementing a count value stored in a count field of said communications control device corresponding to a component of said piece of equipment when a process interlocked with said component occurs; transmitting said count value to said host computer in accordance with predetermined times; comparing said count value received by said host computer with a threshold value stored in said host computer; and issuing a component replacement warning when said count value received by said host computer exceeds said threshold value, and disabling said warning if, during a period after issuance of a component replacement warning for said component and before replacement of said component, another component becomes a target of a component replacement warning.
