Rotating speed measuring point, C2~C6 are vibration measuring point.Rotating speeds of the rotating speed measuring point C1 under current state is D1, and corresponding rotating speed shuts down thresholding
For E1, vibration signal amplitudes of the vibration measuring point C2~C6 under current state is followed successively by F1, F2, F3, F4 and F5, corresponding vibration
It is G1, G2, G3, G4 and G5 respectively to shut down thresholding.Now, the rotating speed for the rotating speed measuring point pending measuring point concentrated is surveyed with the rotating speed
The rotating speed of point is shut down thresholding and is compared, i.e., is compared D1 and E1 to judge magnitude relationship, and respectively by pending measuring point
Compared with thresholding is shut down in the vibration of vibration signal amplitude and the vibration measuring point of each vibration measuring point concentrated, i.e., respectively by F1 and
G1, F2 and G2, F3 and G3, F4 with G4, F5 compared with G5, to judge respective magnitude relationship.
Next, performing step S250, statistical signal numerical value is less than the quantity for the measuring point for shutting down thresholding as the second quantity.
According to one embodiment of present invention, when sensor is vibrating sensor, statistics vibration signal amplitude is less than vibration and shuts down door
The quantity of the measuring point of limit is as the second quantity.In this embodiment, each measuring point is concentrated to pending measuring point by step S240
Vibration signal amplitude and the measuring point vibration shut down thresholding compared with after, it is small that the comparative result that draws for A1 is less than B1, A2
It is less than B3, A4 in B2, A3 and is less than B6 less than B5, A6 less than B4, A5, i.e., pending measuring point concentrates the vibration signal width of each measuring point
Thresholding is shut down in the vibration that value is respectively less than the measuring point, and in other words pending measuring point concentrates the signal numerical value of each measuring point to be respectively less than the survey
The shutdown thresholding of point, count show that the second quantity is 6 accordingly.
According to still another embodiment of the invention, can be by such as when sensor is speed probe or vibrating sensor
Under type statistical signal numerical value is less than the quantity for the measuring point for shutting down thresholding as the second quantity.First, vibration signal amplitude is counted
Less than the corresponding quantity for vibrating measuring point for shutting down thresholding of vibrating as the 4th quantity, if the rotating speed of rotating speed measuring point is less than the rotating speed
The rotating speed of measuring point shuts down thresholding, then using the 4th quantity and 1 sum as the second quantity, if the rotating speed of rotating speed measuring point is not less than this turn
The rotating speed of fast measuring point shuts down thresholding, and the 4th quantity is equal to the 3rd quantity, then using the 4th quantity and 1 sum as the second quantity,
If the rotating speed of rotating speed measuring point shuts down thresholding not less than the rotating speed of the rotating speed measuring point, and the 4th quantity is less than the 3rd quantity, then directly
Using the 4th quantity as the second quantity.In this embodiment, after step S240 processing, the comparative result drawn is D1
It is less than G5 less than G4, F5 less than G3, F4 less than G2, F3 less than G1, F2 less than E1, F1, i.e., pending measuring point concentrates rotating speed measuring point
Rotating speed be less than the rotating speed of the rotating speed measuring point and shut down thresholding, each vibration signal amplitude for vibrating measuring point is respectively less than the vibration measuring point
Vibration shut down thresholding, statistics show that the 4th quantity is 5 accordingly, and the second quantity is the 4th quantity and 1 sum, and its value is 6.
Finally, step S260 is performed, if the second quantity is equal to the first quantity, judges that equipment is in stopped status.According to
One embodiment of the present of invention, sensor are vibrating sensor, and the first quantity and the second number are understood with reference to step S230 and S250
Amount is 6, i.e. the second quantity is equal to the first quantity, now judges that equipment is in stopped status.And when the second quantity is less than first
During quantity, show that pending measuring point concentration has the measuring point that vibration signal amplitude shuts down thresholding not less than vibration, due to being unsatisfactory for
Pending measuring point concentrates the collected vibration signal amplitude of all measuring points less than the condition of the vibration shutdown thresholding of the measuring point, if
It is standby to be judged in start running status.
According to still another embodiment of the invention, sensor is speed probe or vibrating sensor, with reference to step S230
Understand that the first quantity and the second quantity are 6 with S250, i.e. the second quantity is equal to the first quantity, illustrates pending measuring point collection transfer
The rotating speed of fast measuring point be less than the rotating speed measuring point rotating speed shut down thresholding, and it is all vibration measuring point vibration signal amplitude be respectively less than pair
Thresholding is shut down in the vibration answered, and now judges that equipment is in stopped status.In addition, it was found from step S250, the second quantity and first
Quantity is equal also to have another situation, i.e., pending measuring point concentrates the rotating speed of rotating speed measuring point to be not less than the rotating speed of the rotating speed measuring point
Thresholding is shut down, but the vibration signal amplitude of all vibration measuring points is respectively less than corresponding vibration and shuts down thresholding.In this case
Processing, mainly consider when the vibration signal amplitude of all vibration measuring points is respectively less than corresponding vibration and shuts down thresholding, rotating speed
The possibility that the rotating speed that sensor collects is less than corresponding rotating speed shutdown thresholding is very small, and now speed probe may be run
Normal but data acquisition is wrong, or unexpected operation exception, based on this, in these cases sets the second quantity in step S250
The 4th quantity and 1 sum are set to, that is, judges speed probe error and carries out correction process.When the second quantity is less than the first quantity
When, then it can produce two kinds of situations.The first situation is that pending measuring point concentrates the rotating speed of rotating speed measuring point to be less than the rotating speed measuring point
Rotating speed shuts down thresholding, and the vibration measuring point that vibration signal amplitude shuts down thresholding not less than vibration be present, then tendency thinks that rotating speed passes
The rotating speed that sensor is collected at rotating speed measuring point is unreliable, and definition apparatus is in start running status.Second case is to treat
Handling measuring point concentrates the rotating speed of rotating speed measuring point to shut down thresholding not less than the rotating speed of the rotating speed measuring point, and vibration signal amplitude be present not
Less than the vibration measuring point that thresholding is shut down in vibration, it is evident that now will determine that equipment is in start running status.
Existing equipment downtime determination methods, it is mainly simply single using the vibration values average or selection of all measuring points
The vibration data of individual measuring point, compared with the shutdown thresholding set, sensor states is not taken into account that substantially, are easily missed
