This invention belongs to the field of shield tail seal monitoring technology for tunnel boring machines (TBMs), and discloses a real-time monitoring and targeted repair system for the shield tail seal cavity. The system includes: several ultrasonic sensors for monitoring the location of grease loss within the grease cavity; a grease pump that delivers grease into two grease cavities via a first pipeline and a second pipeline, with the output ends of the first and second pipelines providing targeted grease replenishment at the locations of grease loss detected by the ultrasonic sensors; water pressure sensors installed on the shield tail brush plates on both sides of the grease cavity; grout and water pressure sensors installed at the grouting pipe inlets on the TBM; and grease pipe pressure sensors installed at the inlets of both the first and second pipelines; a pressure feedback system that controls the amount of grease injected into the grease cavity via the measured pressure. This invention enables real-time monitoring and targeted repair of grease within the grease cavity.

The present application relates to a multi-dimensional value evaluation method and system for scientific and technological information viewpoints based on fuzzy cumulative prospect theory, the method comprising the following steps: S1: constructing a scientific and technological information viewpoint value evaluation index system and calculating the accurate scores of several dimensions; S2: triangular fuzzy processing the accurate scores of several dimensions and calculating the comprehensive prospect value based on cumulative prospect theory; S3: linear normalization of the comprehensive prospect value of several dimensions to obtain the standardized score; S4: generating the star rating of the scientific and technological information and the corresponding decision suggestion. The system comprises an index calculation module, a fuzzy processing and prospect value calculation module, a linear normalization module and a grade evaluation module. The present application can realize comprehensive, objective and intelligent evaluation of the value of scientific and technological information viewpoints, and provides a scientific, intelligent, practical and interpretable value evaluation solution for the field of scientific and technological information analysis and decision support.
