Whether the signal related to the suspect device meets the corresponding diagnostic rule, if meeting, it is determined that go out described suspicious set
Standby is faulty equipment, if being unsatisfactory for, first suspect device mark is stored in into caching, new signal is continued waiting for, if subsequently
Signal and current existing signal meet the corresponding diagnostic rule, it is determined that it is faulty equipment to go out the suspect device, such as
Fruit cache-time time-out, then by the object that no longer monitors of being classified as of the suspect device, no longer carry out fault diagnosis.
For each signal for receiving, can trigger carries out fault diagnosis, and triggering mode includes that single device is triggered and many
Equipment is triggered.
Single device is triggered：As shown in figure 3, the triggering mode is to receive the unit trip alarm of each alarm source or judge
Equipment telemetry value starts when occurring quickly to fall, and only the faulty equipment to receiving is triggered, and is classified as suspect device, while
The Failure Diagnostic Code of classification belonging to the equipment is obtained, the signal of the equipment for being received and its Failure Diagnostic Code are carried out
Match somebody with somebody, judge whether to meet Failure Diagnostic Code, if meeting, release the alarm of the equipment, if being unsatisfactory for, be first stored in caching,
New signal is continued waiting for, if follow-up signal and current existing signal meet Failure Diagnostic Code, it is determined that for faulty equipment,
Alarm is released, if cache-time is overtime, by the object that no longer monitors of being classified as of the equipment, fault diagnosis is no longer carried out.Need
It is noted that equipment telemetry value occurs quickly to fall refers to the telemetry value range of decrease more than default value, this value specifically can basis
Different equipment are configured.When the equipment for needing to be monitored to it is determined every time, needs check whether deposited in caching
The mark of the equipment is contained, if the mark of the equipment that has been stored with caching, illustrates that the equipment is monitored, now can basis
The signal of the signal of the equipment for receiving before and the equipment for receiving afterwards carries out breakdown judge to it.Otherwise, if in caching
Be not stored with the mark of the equipment, then illustrate that the equipment is not monitored, and now starts to monitor it, can according to just receive with
And the signal of the equipment for receiving afterwards carries out fault diagnosis to it.
Many equipment triggerings：For the remote signalling displacement, SOE signals, accident resultant signal, the protection signal that receive, letter is first looked for
Associated all devices are all classified as suspect device by number associated all devices, while obtaining classification belonging to these equipment
Failure Diagnostic Code, one by one Failure Diagnostic Code matching, rule matching method and single device are carried out to the signal of suspect device
Triggering pattern is identical, and here is omitted.
In the present embodiment, fault diagnosis is triggered using signal, be divided into single device triggering pattern and many equipment triggering pattern, will
The equipment being triggered all is classified as suspect device and is monitored, it is to avoid leakage occurs and accuses.
