Alternatively, described warning can be at least one during sound alarm and light are reported to the police.
Alternatively, the described scheduled time can be 10 seconds.
Alternatively, described difference can be 5 millimeters.
By hydraulic oil oil level monitoring method of the present invention and equipment, can monitor timely hydraulic oil oil level, effectively avoid the manufacturing mechanism accident causing because leakage of oil amount is excessive.
By part in ensuing description set forth the present invention other aspect and/or advantage, some will be clearly by descriptions, or can pass through enforcement of the present invention and learning.
Brief description of the drawings
By the detailed description of carrying out below in conjunction with accompanying drawing, above and other objects of the present invention, feature and advantage will become apparent, wherein:
Fig. 1 shows the flow chart of hydraulic oil oil level monitoring method according to an exemplary embodiment of the present invention;
Fig. 2 shows the block diagram of hydraulic oil oil level watch-dog according to an exemplary embodiment of the present invention.
Embodiment
Below, describe more fully with reference to the accompanying drawings exemplary embodiment of the present invention, exemplary embodiment is shown in the drawings.But, exemplifying embodiment embodiment in many different forms, and should not be construed as limited to exemplary embodiment set forth herein.On the contrary, thereby provide these embodiment's disclosure will be thoroughly and complete, and will fully the scope of exemplary embodiment be conveyed to those skilled in the art.
Fig. 1 shows the flow chart of hydraulic oil oil level monitoring method.
With reference to Fig. 1, at step S101, detect the oil level of hydraulic oil.
Detect the oil level of hydraulic oil so that current oil level is monitored, for example, can periodically detect oil level.Can detect by technology conventional in prior art the oil level of hydraulic oil, for example, can adopt condenser type oil device level sensor to detect the oil level of hydraulic oil.
At step S102, the difference between the oil level of the hydraulic oil detecting before the oil level of definite hydraulic oil detecting and the scheduled time.
Can detect an oil level or periodically detect oil level at interval of a period of time, in the time of each detection oil level, the oil level detecting before the oil level detecting before detected oil level and described a period of time or one-period is compared, in the time that comparative result is greater than predetermined threshold value, can think that oil level declines too fast, sounding leakage of oil.
As an example, can detect oil level at interval of 10 seconds, the result detecting before testing result and 10 seconds is compared, can calculate oil level that difference between twice testing result determines the hydraulic oil detecting and the scheduled time difference between the oil level of the hydraulic oil of detection before.
Difference between the oil level of described hydraulic oil can be that oil level is poor.
Preferably, the described scheduled time can be 10 seconds.
At step S103, in the time that being greater than predetermined threshold value, described difference reports to the police.Described warning can be at least one during sound alarm and light are reported to the police.
When determined difference in step S102 is greater than predetermined threshold value, can think that oil level rate of descent is too fast, there is leakage of oil, for example, in the time that the difference of described testing result and the testing result before 10 seconds is greater than 5 millimeters, can report to the police.Can report to the police by technology conventional in prior art.For example, adopt loudspeaker to carry out sound alarm or adopt warning light to carry out light warning.
Preferably, described difference can be 5 millimeters.
Fig. 2 shows the block diagram of hydraulic oil watch-dog.
With reference to Fig. 2, hydraulic oil watch-dog comprises: testing module 201, determination module 202 and alarm module 203.
