The invention belongs to the technical field of electrified rail transit and power electronic converters, and specifically relates to a subway train position detection system, which includes several position detection units. The position detection unit is used to detect the dynamic change of rail pressure drop, compare the magnitude and product of the voltage output by adjacent position detection units, and then judge the real-time position of the train. The invention has the advantages of dynamic and real-time judgment of the train position, simple principle, low cost, small maintenance amount and the like.

The invention discloses a novel mould material in-frame four-point positioner, which relates to a mould material positioner and comprises a stainless steel module (1) and a four-point positioner (2),wherein the four-point positioner (2) is arranged in the stainless steel module (1); the four-point positioner (2) is arranged in the four-point positioning part of the inner frame of the stainless steel module (1) and breaks through traditional two-point positioning. The novel mould material in-frame four-point positioner meets the requirement for positioning material, at least reduces the widthof the material by 30% to 40%, largely reduces the use cost of the material, meets a product pressing requirement, reduces the length of a mould by 10% to 15% simultaneously and reduces the development cost.

The invention relates to an image processing method for positioning eyes. The invention adopts a technical proposal that the method comprises the following steps of: acquiring an image of a face; and detecting the image of the face, establishing probability support vector machine appearance models for three components including eyes and nose respectively, establishing the Gaussian distribution models of the measuring parameters of the spatial structure of the three components respectively, redefining the length of three edges and establishing Gaussian distribution models, establishing an enhanced image model, selecting candidate points of maximum appearance characteristic similarity and maximum structural similarity as the optimal positions of a target, and determining the possibility of human eyes z1 and z2 or nose z3 according to an appearance characteristic ui shown by the probability support vector machine appearance models on the basis of the probability support vector machine appearance models to position the eyes. The method overcomes the drawbacks in the prior art such as high requirements on image resolution ratio, light and definition, and difficulty in the positioning of the human eyes in a complex environment accurately. The method establishes a high robustness space structural model starting from the appearance characteristics of eyes and the characteristics of the spatial distribution structure of the eyes and the nose and improves human eye positioning accuracy.

The invention discloses a pipeline data processing method, a sending device, a receiving device and a storage medium. The method comprises the following steps: extracting a plurality of groups of position information and access information, calculating confidence, under the condition that a confidence coefficient is higher than a preset first threshold value, the position and orientation, acquiring described by the access information, of the network equipment calculating the distance between the position and orientation and the position information, and outputting corresponding position information under the condition that the distance is smaller than a preset second threshold value. Confidence coefficients according to access information are calculated and the position information is screened according to the confidence coefficients, influences of interference factors such as destinations or simulation positions can be eliminated, the screened position information can accurately reflect the current or historical geographic position of the user terminal, and therefore the requirement for positioning the real geographic position of the user terminal is met. The invention is widelyapplied to the technical field of wireless communication.
