SELF-MONITORING SYSTEM, ESPECIALLY FOR ELECTRICAL DEVICE, PREFERRED FOR A HIGH VOLTAGE SF6 CIRCUIT BREAKER

摘要

The automatic equipment monitoring system includes a number of transducers for measuring operating parameters supplying data to a multiprocessor system. This system comprises stations linked by a local network and constituting a distributed database, and is able to carry on a dialogue with a higher level system comprising a computer with a bridge linked to the network. The bridge is a microcontroller (S4) which is a terminal communicating with stations (S1,S2,S3,S5,S6). Communication is firstly by messages corresponding to requests emitted by the terminal and received by all the stations in a given memory region, and secondly by further messages corresponding to interrogated station response.
