The working principle is that the friction force between the silk and the sensor is utilized, the lever balance principle is applied to reflect the change of the fineness of the raw silk, and the raw silk is sensed when the fineness reaches the fineness limit, namely the fineness limit value of the raw silk which needs to be added when the fineness of the raw silk is thinned to a certain limit.
In the past, the working motion of the sensor in the sensing frame is not monitored. The sensor can have abnormal working state, 1. the sensor is hung in the middle of the frame because of the blockage of the silks in the sensor due to the reasons of silks, nodes and the like, and the diameter of the silks cannot be sensed in exploration, so that the silks are thin. 2. The sensor is mechanically influenced and the sensor is clamped in the frame so that the thread is not controlled. 3. The silk thread does not enter the working surface of the sensor, and the sensing of the silk thread by the sensor is lost, so that the wild stripes are generated.
The conventional sensor works in an atmospheric environment, the working environment changes along with the change of the humidity of ambient air, so that the humidity between the working surface of the sensor and the silk strips changes, the change of the humidity causes the change of the friction coefficient between the working surface and the silk strips, and the changed friction coefficient directly causes the change of the titer of the silk strips to cause the increase of the mean square error of the silk strips.
