Embodiments of the present disclosure disclose a model training method and device and electronic equipment. The method comprises: obtaining a target road section set corresponding to a sample route and route additional information corresponding to the sample route; the target road section set comprises at least one target road section on the sample route, the length of the target road section, and the road characteristics of the target road section; clustering the target road sections in the target road section set based on the road characteristics; and training a machine self-learning model based on the clustering results corresponding to the sample route and the route additional information to determine the class additional information corresponding to the target road section category. This technical solution can accurately predict the route additional information of a new route when a new road section that has not appeared in the sample route appears in the new route.

The invention discloses a familial defect identification method for an industrial control system of a hydropower station, which belongs to the technical field of automatic control of hydropower stations and comprises the following steps of: dividing each functional unit according to functions and coding; constructing a dual-identification feature vector set containing multiple feature vectors, and carrying out sorting and normalization processing; determining the weight of each feature vector by adopting a subjective and objective combination weighting method; based on the healthy function unit, calculating and obtaining an identification reference vector; calculating a first relative Euclidean distance d1, a second relative Euclidean distance d'ia and a familial defect difference degree d2; constructing an ROC working curve based on historical data and performing dynamic adjustment to obtain a dynamic distance adjustment threshold value y0; comprehensively judging the familial defect condition of each functional unit; and finally, according to the generality of the clustered family defects, defect root tracing is carried out. According to the invention, identification accuracy and timeliness of familial defects can be improved, early warning can be carried out on the industrial control system, and defect tracing can be carried out on the basis.

This utility model belongs to the field of manhole dredging construction, and particularly relates to an integrated device for manhole dredging and protection in drainage pipe networks. It includes two symmetrical protective frames, with a long rod fixed in the middle of each secondary protective frame. Several short rods are vertically connected between the long rod and the inner long frame. Several inverted U-shaped buckles are welded outwards to the inner side of the secondary protective frame. It also includes a main protective frame, with its two long frames respectively engaged with the inverted U-shaped buckles on both sides. The length of the main protective frame is adjustable, and support rods are fixed on both sides of the main protective frame, with stop bars fixed to the bottom of the support rods. A fixed shaft is fixed on the main protective frame, and a pulley is rotatably connected to the fixed shaft, located between the two stop bars. This invention provides a large coverage area, stable structure, and ensures safety. It avoids the manhole cover location, ensuring the protected area is not affected by the manhole cover. Furthermore, the length of this invention can be adjusted according to the size of the manhole opening, making it suitable for manhole dredging work of different diameters and highly versatile.

The invention provides a vehicle function testing method, a vehicle machine and a storage medium, and relates to the technical field of vehicle testing. The method comprises the following steps: acquiring a multi-screen cooperation event from a preset test event set in a vehicle function test process; based on the multi-screen cooperation event, obtaining a test script associated with the multi-screen cooperation event from a preset database; executing a test script associated with the multi-screen cooperation event to control the multi-screen cooperation event of at least two physical screens in the plurality of physical screens; and detecting whether the multi-screen cooperation event is normally executed, and generating a first test result based on a detection result. Therefore, the multi-screen cooperation function of the vehicle can be tested, the coverage of a test scene is enlarged, the integrity of the test of the vehicle function is improved, and the reliability is high.
