Illustrative methods
Embodiment one
Referring to Fig. 1, which is a kind of control method of high-speed rotating machine equipment provided in an embodiment of the present invention, this method
Include the following steps：
S101：During mechanical equipment operates, the current rotating speed and current acceleration of the mechanical equipment are monitored.
S102：Current rotating speed threshold value is determined according to the current acceleration monitored.
Wherein, the current rotating speed threshold value is first default if the current acceleration is less than predetermined acceleration threshold value
Rotary speed threshold value, the current rotating speed threshold value works as preacceleration by described if the current acceleration is more than predetermined acceleration threshold value
Degree, which reduces the first preset rotation speed threshold value, to be obtained.
In the present embodiment, when mechanical equipment operation, the current rotating speed and current acceleration of mechanical equipment are monitored, and
Current rotating speed threshold value is determined according to the current acceleration monitored.If current acceleration is more than predetermined acceleration threshold value, start
Acceleration protection mechanism is reduced to obtain current rotating speed threshold value, that is, is dropped according to current acceleration pair the first preset rotation speed threshold value
Low first preset rotation speed threshold value, if monitoring, the current rotating speed of mechanical equipment has been more than current rotating speed threshold value, executes step S103.
If current acceleration is less than predetermined acceleration threshold value, can not starting loop protection mechanism, mechanical equipment
Current rotating speed threshold value be still the first preset rotation speed threshold value, if monitoring that the current rotating speed of mechanical equipment is more than first default turn
Fast threshold value, thens follow the steps S103.
By above-mentioned it is found that when the current acceleration of mechanical equipment is more than default acceleration threshold value, starting loop is protected
Mechanism.And in practical applications, in some embodiments of the present embodiment, it can be provided with the second preset rotation speed on this basis
Threshold value, when the current rotating speed of mechanical equipment is more than the second preset rotation speed threshold value, then starting loop protection mechanism, that is,
S102 can be specially：If the current rotating speed is more than the second preset rotation speed threshold value, determined according to the current acceleration monitored
Current rotating speed threshold value；Wherein, the second preset rotation speed threshold value is less than the first preset rotation speed threshold value.

Inertia and be arranged.The inertia of mechanical equipment is bigger, i.e., acceleration changes slower, then K is bigger, i.e. the first preset rotation speed threshold
The downward ratio of value is bigger；If inertia very little, acceleration changes quickly, and systematic comparison is sensitive, then K can be turned down, then first
The downward ratio of preset rotation speed threshold value is smaller.
It should be noted that in practical application, predetermined acceleration threshold value, the first preset rotation speed threshold value, the second preset rotation speed
The specific value of threshold value can be set according to the performance and/or correlation experience of mechanical equipment.
S103：If the current rotating speed monitored is more than the current rotating speed threshold value, controls the mechanical equipment and shut down.
In the present embodiment, when the current rotating speed of mechanical equipment is more than current rotating speed threshold value, control machinery equipment stops fortune
Turn, avoids rotating speed is too fast from leading to abuse.
Using the control method of high-speed rotating machine equipment provided in an embodiment of the present invention, for the high speed in operation process
For rotating machinery, the current rotating speed threshold value for limiting rotating speed is arranged by the current acceleration monitored, works as institute
State current acceleration it is excessive when can on the basis of preset rotary speed threshold value suitably reduce be used as current rotating speed threshold value, in this way,
On the one hand so that acceleration occur fluctuating but rotating speed also not close to preset rotary speed threshold value when mechanical equipment will not be turned off, from
And the case where avoiding mistakenly stop machine, on the other hand make excessive in acceleration and rotating speed is caused to be increased rapidly to close to preset rotating speed
Mechanical equipment can be turned off when threshold value, to avoid safety accident, hereby be achieved that, in the case where avoiding mistakenly stop machine,
It realizes and shutdown control is carried out to mechanical equipment based on acceleration, to the risk for avoiding rotating speed excessive, exclude the hidden of safety accident
Suffer from.
