Maintenance system for an equipment set
First Claim
1. A maintenance system comprising:
- a plurality of equipment units each associated with a monitoring unit, the monitoring unit being configured to monitor the respective equipment unit, the monitoring unit including,a test unit configuredto test proper operation of each equipment unit andto issue fault messages when testing indicates a failure of the respective equipment unit, anda non-volatile memory unit configured to store at least the fault messages;
a central maintenance unit configured to communicate with test units of the plurality of equipment units, the central maintenance unit including a diagnosis unit configuredto check a state of the plurality of equipment units by using the fault messages, andto generate a report on an overall state of operation of the maintenance system; and
a data transmission link configured to provide a data connection between the plurality of equipment units and the central maintenance unit,whereinthe central maintenance unit makes the report available on the data transmission link, andeach of the plurality of equipment units include a detection circuit configuredto detect and capture the report from the data transmission link, andto transfer the report from the data transmission link into a respective non-volatile memory unit after the report is available on the data transmission link.

Abstract
A rapidly installable and rapidly removable set of equipment (1-6, 11) which can be replaced by standard exchanges, furnished with individual electronic circuits for monitoring proper operation (1a-6a, 20a-23a, 30a-32a, 1 1a) assuming, at their level, a BITE function (Build [sic] In Test Equipment) for testing, for fault diagnosis and for issuing fault messages sent by data transmission to a central maintenance computer (7) itself formulating a report regarding the overall state of operation of the set of equipment. It relates more especially to the hardware parts of the electronic circuits for monitoring proper operation which are integral with the equipment (1-6) or with equipment parts (20-23, 30-32) and which are furnished with a nonvolatile memory (405) and by means of detection, selection and capture (403, 413, 423) into their nonvolatile memories (405), of the report formulated by the central maintenance computer (7). Since these hardware parts of circuits for monitoring proper operation track the tribulations of the equipment parts or pieces of equipment with which they are integral, they make it possible for the latest report regarding the overall state of operation of the set of equipment often causing the removal, to be always available, in a repair center, with an item removed for repair, thereby facilitating the drawing up of a repair diagnosis.
