Abstract: A device and method for detecting an angle of a shearer rocker arm based on optical fiber sensing. The device includes an optical system and a mechanical system. The optical system includes a broadband light source, a polarizer, collimating lenses, a gradient-rotation media plate, a polarization beam splitter, and a data processing module. The mechanical system includes a connecting base, connecting rods, a slider, a bracket, and a sensor housing. When the shearer operates, the rocker arm converts rotation angle information to linear displacement related to a gradient refractive index by using a connecting rod mechanism, and a position on the gradient-rotation media plate through which linearly polarized light produced by the optical system passes also changes. Due to an optical rotation effect, corresponding rotation angles of a plane of polarization that are formed after the light passing through the gradient-rotation media plate also vary.

Abstract: When the heading machine tunnels, a current generated by a current excitation source enters a coal seam through a movable cutting pick to form a stray current. The stray current collected by a backflow net returns to a negative electrode of a power supply through a transition resistor. When information such as the water content of the coal seam changes, the stray current and a potential difference across the transition resistor also accordingly change, and the coal seam water content information is converted into an electric signal. When the potential difference across the transition resistor is applied to two ends of a piezoelectric ceramic, the piezoelectric ceramic extends or compresses, and the electric signal is converted into a strain signal. A sensing optical fiber converts the strain signal into an optical signal detectable by a photoelectric detector. The optical signal is analyzed to obtain the coal seam water content information.

Abstract: In a video quality assessment method, an assessment model is first generated based on a subjective assessment result of a user on each sample in a sample set and based on a parameter set (a parameter type in the parameter set may include at least one of a packet loss rate, a delay, and a jitter) of each sample. Therefore, when video quality is being assessed, a parameter set of a to-be-assessed video is obtained first, where the parameter set of the to-be-assessed video has a same parameter type as the parameter set of each sample that is used to generate the assessment model; and then video quality of the to-be-assessed video is assessed based on the assessment model and the parameter set of the to-be-assessed video, to obtain an assessment result.
