Embodiment
Below based on embodiment, present invention is described, but the present invention is not restricted to these embodiments.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for those skilled in the art
For, the present invention can have various changes and change.All any modifications made within spirit and principles of the present invention, it is equal
Replace, improve etc., it should be included in the scope of the protection.
Fig. 1 is the flow chart of the fault monitoring method for equipment of one embodiment of the invention.
As shown in figure 1, in a step 101, obtain the malfunction monitoring parameter of equipment.
In the present embodiment, can be by the computing device fault monitoring method that is arranged in equipment.Processor can be first
First according to certain time interval, the malfunction monitoring parameter of equipment is obtained.Wherein, malfunction monitoring parameter can be that those being capable of table
The parameter of equipment working state is levied, can be set according to the actual functional capability of equipment.For example, for most of electrical equipment,
Current value or magnitude of voltage in its circuit can be used for characterize equipment whether normal operation.For the equipment with heating function,
Whether the temperature of its heater block can be used for characterizing its heating function normal.It should be noted that above-mentioned time interval can be with
Set, if for example, to realize the real-time monitoring to equipment fault, can be use up what time interval was set according to the actual requirements
May be short.
Specifically, processor is obtaining the malfunction monitoring parameter of equipment, can be used according to the property of malfunction monitoring parameter
Different acquisition modes.For example, if malfunction monitoring parameter is current value or magnitude of voltage, processor can be directly from corresponding electricity
Current value or magnitude of voltage are sampled in road.If malfunction monitoring parameter is temperature value, a temperature can be set with sampling location
Sensor is spent, and obtained temperature value is sent to processor by the temperature sensor.
In a step 102, malfunction monitoring parameter is obtained into malfunction monitoring knot compared with the alarm door limit value set
Fruit.
In the present embodiment, processor obtain equipment malfunction monitoring parameter after, can by malfunction monitoring parameter with
The alarm door limit value of setting is compared, to determine whether equipment breaks down.Wherein, the specific value of alarm door limit value can be with
Be equipment production firm according to conventional equipment using empirically determined.When malfunction monitoring parameter exceeds the alarm door limit value
When, equipment is likely to break down.
Alternatively, processor can be by the malfunction monitoring parameter of acquisition compared with the alarm door limit value set.If
The malfunction monitoring parameter falls beyond above-mentioned alarm door limit value, then can determine device fails, and export warning message；It is no
Then, it may be determined that equipment does not break down.Specifically, output warning message can include：Pass through the loudspeaker configured in equipment
An alert audio is played, or the display by being configured in equipment shows an alarm screen.
In step 103, the actual motion state of the equipment of user feedback is obtained.
In the present embodiment, user can pass through the input module (such as keyboard, microphone or touch-screen) of device configuration
Carry out the actual motion status information of input equipment.Or user can on the mobile device of oneself input equipment actual motion
Status information, and the information is sent to by mobile device the processor of equipment by communication network.Processor obtain it is above-mentioned
After actual motion status information, it is possible to which the true running status for determining equipment is normal or abnormal.
At step 104, based on malfunction monitoring result and actual motion state, alarm door limit value is updated.
Processor is obtaining the actual motion state of malfunction monitoring result and equipment respectively from above-mentioned steps 102 and 103
Afterwards, the alarm door limit value set before can be updated according to the concrete condition of the two.Wherein, malfunction monitoring result is anti-
What is reflected is the equipment fault situation judged according to alarm door limit value, and the reflection of the actual motion state of equipment is the true of equipment
Real failure situation, therefore whether the two can unanimously reflect the accuracy of alarm door limit value to a certain extent.
If the actual motion state consistency of malfunction monitoring result and equipment, such as equipment have carried out fault alarm and equipment
Actual motion is abnormal, then it may be said that the setting of contract quotation police's threshold value is more reasonable, can now keep alarm door limit value constant.Such as
The actual motion state of fruit malfunction monitoring result and equipment is inconsistent, then it may be said that the setting of contract quotation police's threshold value is unreasonable, this
When then need to be updated alarm door limit value.Such as equipment has carried out fault alarm but equipment actual motion is normal, then may be used
To think that alarm range that the alarm door limit value is set is too strict, it is necessary to is become loosely a bit, to avoid unnecessary mistake
Alarm；Equipment does not carry out fault alarm but equipment actual motion is abnormal, then it is considered that the alarm that the alarm door limit value is set
Scope it is too loose, it is necessary to is become strictly a bit, to carry out fault alarm in time.
Above-mentioned steps 101 to 104, and the malfunction monitoring that will newly obtain in a step 102 can be performed with repetitive cycling afterwards
Parameter is compared with the alarm door limit value after renewal, to determine whether to carry out fault alarm.
The fault monitoring method for equipment that the present embodiment provides, the event based on malfunction monitoring parameter can be obtained simultaneously
Hinder the actual motion state of monitoring result and equipment, and be based further on alarm threshold of both next state to fault alarm
Value is modified, and to improve the accuracy of equipment fault monitoring, while ensureing that equipment runs well, it is unnecessary to reduce
False alarm.
Fig. 2 is the flow chart of the fault monitoring method for equipment of another embodiment of the present invention.
As shown in Fig. 2 in step 201, obtain the malfunction monitoring parameter of equipment.
In step 202, malfunction monitoring parameter is obtained into malfunction monitoring knot compared with the alarm door limit value set
Fruit.
In step 203, the actual motion state of the equipment of user feedback is obtained.
In the present embodiment, step 201 will not be repeated here to 203 respectively with the step 101 in Fig. 1 to 103 identical.
In the present embodiment, by setting a thresholding to update weights to judge whether current alarm door limit value is reasonable.
The thresholding renewal weights are adjusted according to whether each relatively malfunction monitoring result and actual motion state are consistent, in thresholding more
New weights meet renewal of the triggering for alarm door limit value during predetermined condition.
After malfunction monitoring result and actual motion state is obtained, processor can be based further on the two renewal and carry out event
Hinder the alarm door limit value of alarm.According to malfunction monitoring result and the concrete condition of actual motion state, the present embodiment also includes step
Rapid 204 to 206.
In step 204, do not broken down if malfunction monitoring result is equipment, and actual motion state is operation exception,
Then reduce the thresholding renewal weights.
In the present embodiment, do not broken down if malfunction monitoring result is equipment, and actual motion state is different to run
Often, then physical device is illustrated there occurs failure, but processor does not carry out fault alarm in time.Cause this to fail to report alert original
Because essentially consisting in the excessively loose of the condition setting alarmed, i.e., the alarm range that current alerts threshold value is set is too small, no
The monitoring parameters numerical value under all malfunctions can be included.
In the present embodiment, thresholding renewal weights are preset as 1, and the amplitude adjusted every time can be set according to being actually needed, example
Such as, the amplitude adjusted every time is 0.1.
For example, it is assumed that the alarm door limit value that certain device current is set is 20A, i.e., when device current is more than 20A alarms.Such as
There is exception in the present equipment actual motion of fruit, but monitoring current only has 18A, and malfunction monitoring result is " fault-free ", then illustrates
The alarm range that alarm door limit value is formed when being 20A is too small, and the thresholding renewal weights are reduced in the case of this kind, then will be originally
1 thresholding renewal weighed value adjusting is 0.9.If the monitoring of fault detect next time is identical with this, the thresholding updates weights
It may proceed to adjust, 0.8 be adjusted to by 0.9；By that analogy, repeat no more here.
In step 205, if malfunction monitoring result is device fails, and actual motion state is operation exception, then
Improve thresholding renewal weights.
In the present embodiment, if malfunction monitoring result is device fails, and actual motion state is operation exception,
Then illustrate physical device there occurs failure, and processor has also carried out fault alarm in time.This illustrates current alarm threshold
Value setting is rational.The thresholding renewal weights are improved in the case of this kind.Because equipment is all normal work in most cases
Make, therefore, can be that the thresholding updates weights setting maximum, maximum is adjusted in thresholding renewal weights
Afterwards, thresholding renewal weights are not further added by.
In step 206, if malfunction monitoring result is device fails, and actual motion state is normal operation, then
Reduce the thresholding renewal weights.
In the present embodiment, if malfunction monitoring result is device fails, and actual motion state is normal operation,
Then illustrate that physical device does not break down, but processor has carried out fault alarm.The reason for causing this false alarm master
The condition setting for being to be alarmed it is excessively strict, i.e., the alarm range that current alerts threshold value is set is excessive, includes
Monitoring parameters numerical value under the non-faulting state of part.
In step 207, if malfunction monitoring result is does not break down, and actual motion state is also normal operation, then
Improve the thresholding renewal weights.
In a step 208, judge whether the thresholding renewal weights are less than default thresholding renewal threshold value, if it is,
209 are gone to step, if it is not, then returning to step 201, carries out the judgement of next cycle.
In the present embodiment, thresholding renewal threshold value is arranged to 0.7.
In step 209, alarm door limit value is updated.
Wherein it is possible to new alarm door limit value is calculated according to predetermined more new algorithm, such as be repeatedly averaging etc..Calculating
, can be included by the historical operating parameter of equipment during new alarm door limit value.
After alarm door limit value is updated, its thresholding renewal weights are also reset as initial value.
The present embodiment is described further below by specific example.Assuming that the alarm door limit value of certain device current is
20A, i.e., when device current is more than or equal to 20A alarms.If within some monitoring week, there is exception in equipment actual motion,
Monitoring current is 20A simultaneously, and malfunction monitoring result is " failure ", then the threshold condition before illustrating relatively is adapted to.Thus,
Thresholding renewal weights are brought up to 1.1 by initial value 1.Subsequently, if monitoring current is 18A next time, malfunction monitoring result is " event
Barrier ", but equipment actual motion is normal, then thresholding renewal weights is reduced into 1 by 1.1.If follow-up 4 appearance events in succession again
Hinder monitoring result and actual motion shape is inconsistent, then thresholding renewal weights are reduced by 0.1 every time so that thresholding renewal weights drop
It is low to 0.6.Now, because thresholding renewal weights are less than default thresholding renewal threshold value 0.7, therefore, system assert current report
Alert threshold value needs to update, and starts the renewal to alarm door limit value, and it is initial value to reset thresholding renewal weights.
Thus, update whether weights are rationally evaluated current alerts threshold value by thresholding, according to malfunction monitoring knot
The comparative result of fruit and actual motion state adjustment thresholding renewal weights, alarm door limit value cause malfunction monitoring result repeatedly with
When actual motion state is inconsistent so that when the thresholding renewal weights after adjustment reach default thresholding renewal threshold value, startup pair
In the renewal of alarm door limit value, reduce repeating for unnecessary warning message, allow the alarm of equipment to meet actual condition, keep away
Exempt from insignificant repetition of alarms.
