Warning message is sent to machine short message way the equipment management personnel specified.SMS notification function includes two parts content, one
It is the appointment of equipment person liable, two is short message filtering and issue, generally, to not being very urgent alarm, if
Standby person liable need not in time obtain alarm and the alarm is processed, accordingly, it would be desirable to warning message is filtered, will
The timely annunciator person liable of emergency alarm.Alarm has dividing for the order of importance and emergency, in order to allow urgent warning message preferentially to obtain
Treatment, it is ensured that system safe and stable operation to alarm signal, it is necessary to be classified, i.e., alert levels are set.System will alarm level
It is not divided into 3 grades, urgent fault alarm, catastrophe failure alarm, generic failure alarm third gear is correspond to respectively, client can basis
It is actually needed selection and part or all of warning message is sent to the equipment person liable that specifies by short message pattern, also can be according to
The rank of failure is by certain grade and the failure of higher level is reported by short message and gives equipment person liable.Alarm additional information refers to work as
The situation for being likely to occur problem that alarm occurs is preset in systems, when alarm occurs, Systematic selection one kind most phase
As reason be displayed in interface, to operating personnel solve the problems, such as alarm provide reference.
