In the present embodiment, the present invention carries out real-time monitoring by the actual parameter to smoke exhaust ventilator, and counts
The average value of actual parameter is calculated, is compared with default characteristic by by average value, can learnt pre-
Whether in normal range (NR), whether the operation exception that can interpolate that now has lampblack absorber constitutes event to alert difference
Barrier, influences the realization of smoke exhaust ventilator various functions, and accurate offer failure is pre- before smoke exhaust ventilator breaks down
Alert prompting, the risk that smoke exhaust ventilator failure brings is reduced in the dining room business stage to greatest extent.
It is real relative to upper one the embodiment of the invention discloses a kind of specific smoke exhaust ventilator fault early warning method
Example is applied, the present embodiment is further illustrated and optimizes to technical scheme.Specifically：
Further, the data for being produced when smoke exhaust ventilator stable operation within a period of time are canonical parameter,
In order to obtain default characteristic, compared when being easy to smoke exhaust ventilator actual motion afterwards, it is described default
The acquisition process of characteristic is：
Step S131：Obtain the canonical parameter when smoke exhaust ventilator normally runs；
Step S132：The average value and standard deviation of the canonical parameter are calculated, when the standard deviation is less than
During preset standard difference, using the average value of the canonical parameter as default characteristic.
Further, in order that fault pre-alarming prompting in above-mentioned smoke exhaust ventilator fault early warning method according to
The order of severity of failure is divided into several grades, more facilitates and accurately predicts failure, and according to pre-
The failure of survey proposes corresponding specific solution, described to send fault pre-alarming according to the early warning difference and carry
Show, specifically include：
Step S141：The maximum early warning difference of setting；
Step S142：If the early warning difference sends needs more than the 30% of the maximum early warning difference
The fault pre-alarming prompting of maintenance；
If the early warning difference is more than the 60% of the maximum early warning difference, sending needs the failure changed pre-
Alert prompting.
Further, in above-mentioned steps S131, the canonical parameter is standard general power, calibration power
Factor or standard active power, the actual parameter are actual general power, actual power factor or reality
Border active power.
When being run due to smoke exhaust ventilator, fluctuation of its different parameters in the range of certain numerical value indicates oil pumping
Cigarette machine itself there occurs different abnormal conditions, in order to more accurately predict the event that smoke exhaust ventilator breaks down
Barrier content, is easy to select different maintenance programs for different defect contents.
Further, in above-mentioned steps S14, when the canonical parameter is standard general power, and the reality
It is described to send fault pre-alarming prompting, specific bag according to the early warning difference when border parameter is actual general power
Include：The failure that there is external or inherent mechanical resistance on smoke exhaust ventilator is sent according to the early warning difference
Early warning content.
Specifically, general power is that the overall failure of smoke exhaust ventilator is judged, when the parameter for obtaining is total
Power, and the early warning difference for obtaining more than the maximum early warning difference 30% when, then show that smoke exhaust ventilator is deposited
It is external or it is interior mechanical resistance, it is necessary to overhauled to the inside and outside of smoke exhaust ventilator, go
Except mechanical resistance so that smoke exhaust ventilator recovers normal operation.When the parameter for obtaining is general power, and obtain
Early warning difference more than the maximum early warning difference 60% when, then show smoke exhaust ventilator by either internally or externally
Mechanical resistance destroy, it is necessary to the smoke exhaust ventilator for more renewing.
Further, in above-mentioned steps S14, when the canonical parameter is calibration power factor, and institute
It is described to send fault pre-alarming prompting according to the early warning difference when stating actual parameter for actual power factor,
Specifically include：Sent on smoke exhaust ventilator internal mechanical structural wear and size according to the early warning difference
The fault pre-alarming suggestion content of precise decreasing.
Specifically, power factor is the failure local to smoke exhaust ventilator judge, when the parameter for obtaining is
Power factor, and the early warning difference for obtaining more than the maximum early warning difference 30% when, then show oil pumping
The mechanical structure abrasion of some parts easy to wear of cigarette machine and dimensional accuracy decline, it is necessary to smoke pumping
The inside of machine is overhauled, and repairs wearing terrain, improves dimensional accuracy so that smoke exhaust ventilator recovers normal
Operation.When the parameter for obtaining is power factor, and the early warning difference for obtaining is more than the maximum early warning difference
60% when, then show smoke exhaust ventilator because the local part that is worn causes failure, it is necessary to change in time
The part that is worn of smoke exhaust ventilator.
Further, in above-mentioned steps S14, when the canonical parameter is standard active power, and institute
It is described to send fault pre-alarming prompting according to the early warning difference when stating actual parameter for actual active power,
Specifically include：The circuit sent inside on smoke exhaust ventilator according to the early warning difference exist it is aging short circuit or
The fault pre-alarming suggestion content of open circuit.
Specifically, active power is the failure local to smoke exhaust ventilator judge, when the parameter for obtaining is
Active power, and the early warning difference for obtaining more than the maximum early warning difference 30% when, then show oil pumping
There is aging short circuit or open circuit, it is necessary to be overhauled to the internal wiring of smoke exhaust ventilator in the circuit inside cigarette machine,
So that smoke exhaust ventilator recovers normal operation.When the parameter for obtaining is active power, and the early warning difference for obtaining
More than the maximum early warning difference 60% when, then show that smoke exhaust ventilator is aging because internal circuit is present
Short circuit or open circuit and fail, it is necessary in time change smoke exhaust ventilator circuit.
It is pointed out that in the present embodiment, the active power parameter of acquisition is three phases active power parameter,
If a wherein phase, two-phase or three-phase prediction occurring, judge that the circuit inside smoke exhaust ventilator is present old
Change short circuit or open circuit.
Concrete operation process, for example, the A phase active power data of every 10 minutes acquisition smoke exhaust ventilators,
Continuous operation about 10 hours, will have 600 time point datas, by 30000 times daily daily
The data of point are analyzed, and obtain the average value of A phase active power for 3690W, and standard deviation is 48.2,
Poor less than preset standard 60, assert that A phases active power is default characteristic, characteristic value is 3690W,
It is 200 to set maximum early warning difference, and the later stage continues Monitoring Data, is carried out by window of 3000 time points
Digital filtering is slided, if detecting the filtered data of A phase active power and default characteristic
Up to being more than 60, then send needs the fault pre-alarming for carrying out ad hoc inspection and repair to point out to the difference of 3690W, if inspection
Data are measured with the difference of 3690W more than 120, then warning needs to carry out major tune-up and considers to change.
