With reference now to accompanying drawing, describe embodiments of the invention, similar element numbers represents similar element in the accompanying drawing.As mentioned above, the invention provides a kind of transmission double-chain synchronism monitoring method and device, the double-stranded synchronism of its in real time precise monitoring transmission, and then prevent fault, the testing result reliability is high and easy to implement.
Elaborate the technical scheme of the embodiment of the invention below in conjunction with accompanying drawing.As shown in Figure 1, the transmission double-chain synchronism monitoring method of the present embodiment may further comprise the steps.
Step 201: the respectively displacement of the front-end and back-end of every chain of detected transmission two strands.Particularly, this step can realize by position coder, and mode is simple, and survey precision is high.This step also can realize by modes such as coded scales.Alternatively, the also only displacement of the front end of every chain of detected transmission two strands or rear end.
Step 202: judge the double-stranded synchronism of described transmission according to the displacement of the front-end and back-end of the every chain that detects.
Further, this step comprises: calculate the difference of displacement of the rear end of the difference of displacement of front end of double-stranded two chains of transmission and two chains, if described difference all less than the predetermined value of correspondence, then the double-stranded synchronism of described transmission is normal; If at least one in the described difference surpasses corresponding predetermined value, the double-stranded synchronism mistake of described transmission then.
Further, this step also comprises: calculate the difference of displacement of the front-end and back-end of every chain, if described difference all less than the predetermined value of correspondence, then the double-stranded synchronism of described transmission is normal; If at least one in the described difference surpasses corresponding predetermined value, the double-stranded synchronism mistake of described transmission then.Particularly, the difference of the displacement of the front-end and back-end by calculating every chain, judge according to this difference whether stretching is unusual, whether the situations such as chain jamming, chain rupture perhaps appear, if because in case one-sided chain chain jamming or chain rupture, difference moment of this side chain bar front-end and back-end displacement will exceed predetermined value, can at once report to the police.
Fig. 2 has shown that the present invention transmits the structured flowchart of an embodiment of double-chain synchronism monitoring device.As shown in Figure 2, the transmission double-chain synchronism monitoring device of the present embodiment comprises detection module 21 and control module 22.Wherein, described detection module 21 is used for detecting respectively the front end of every double-stranded chain of described transmission and/or the displacement of rear end; Described control module 22 is judged the double-stranded synchronism of described transmission for the front end of the every chain that detects according to described detection module 21 and/or the displacement of rear end.
