NETWORK MANAGEMENT SYSTEM

摘要

It is to realize a network management system which can suppress to a minimum a time during which it is impossible to make a communication when a trouble occurs in any of field wireless management stations formed to be redundant.;In a network management system in which field wireless management stations 11, 12 having gateway functions and system management functions incorporated are redundantly connected together, the field wireless management stations 11, 12 include at least switch modules 11b, 12b, and the plurality of field wireless management stations 11, 12 are connected to each other through a synchronizing cable 30 and synchronizing connectors CNa, CNb provided in the synchronizing cable 30, and switches SWm are connected in series to a synchronizing system which connects the switch modules 11b, 12b to each other to turn on and off the system.
