In the embodiments of the present disclosure, for avoid in monitoring process various unexpected problems occur (including external disturbance,
Sensor and a certain paths problem of cable line fault or instrument itself etc.), cause the monitoring control at important monitoring position to lose
Accidentally, redundancy of effort mode and early warning, alarm strategy setting function are devised.
No matter Multi-channel Vibration Signals input terminal receives different the first vibration signal of the road n or Multi-channel Vibration Signals input
The same vibrating sensor of two or more connections in end or the vibration signal of two or more connections derive from same monitoring
The different vibrating sensors at position can take following operation that can carry out redundancy monitoring or the partial redundance prison of vibration signal
The mixed mode that control is usually monitored with part.
It can be by early warning channel control unit 61, alarm channel control unit 62 to redundancy of effort mode, prediction policy
It is configured with alarm strategy.One group " redundancy of effort mode passageway group " is formed by any m channel for example, can be set, in advance
As long as alert, alarm strategy may be configured as meeting or exceeding early warning, alarm limits value when the signal in a channel in m monitoring channel
When just export corresponding early warning scene device control signal or alarm scene device control signal.In addition, it is " superfluous to may be alternatively provided as this
X channel signal in m monitoring channel in remaining operating mode channel group " meets or exceeds early warning, alarm limits value simultaneously
When export corresponding early warning scene device control signal or alarm scene device control signal, wherein x is less than or equal to m.
At this point, each module believes the second vibration in the signal output channels for not being incorporated into " redundancy of effort mode passageway group "
Number processing it is identical as normal operating conditions, remaining module is corresponding to m monitoring channel in " redundancy of effort mode passageway group "
M the second vibration signals processing it is also identical as normal operating conditions.
Functionally, the vibration monitor system that the disclosure provides has multi channel signals automatic early-warning, alarm decision and output
It is also independent to have the function of the judgement instruction of multiple signals maximum value channel and maximum value screening and indicate while control, and can make
It is exported for another way early warning, alarm signal, output signal can be used for early warning, warning note or control.In addition, having pre- pithy
Slightly, alarm strategy setting and redundancy of effort mode are, it can be achieved that marshalling monitoring, redundancy monitoring, allow user's flexible setting to each
The monitoring strategies of signal output channels.It, can be in office by the amplitude of maximum second vibration signal of real-time display signal amplitude
Meaning is prompted before the second vibration signal reaches default early warning value, preset alarm value all the way, is mentioned during engine test
Before take counter-measure to be of great significance.
In performance, independent parallel monitoring is carried out to the second vibration signal of the road n respectively, there is reliability in circuit realization
Height, response is fast, precision is high, strong antijamming capability, the advantage that environmental suitability is strong, Operation and Maintenance is simple.
In conclusion the Multi-channel Vibration Signals monitoring device that the embodiment of the present disclosure provides can monitor simultaneously engine and set
The vibration signal variation of multiple vibration monitoring points during received shipment row, judges automatically the maximum value in Multi-channel Vibration Signals, indicates
The corresponding input channel of maximum vibration or monitoring point, and indicate the numerical value of its maximum vibration；According to the vibration of different monitoring object
Monitoring requirement presets early warning value and alarming value, according to preset early warning, alarming value, carries out to per vibration signal all the way
