The invention discloses a multi-access point (AP) coordinated transmission method, device and equipment, and belongs to the technical field of communication. The multi-AP coordination transmission method comprises the following steps: a first AP sends a coordination request frame to one or more second APs in a multi-AP coordination candidate set list; the first AP receives a coordination request reply frame, and forms an AP coordination set with the second AP replying to accept coordination; the first AP divides stations STA associated with each AP in the AP coordination set into different types of candidate sets by initiating channel measurement, and obtains time-frequency resource demand information of each candidate set and power control parameters adopted by each AP in the expected AP coordination set; the first AP generates TWT SP decision information according to the time-frequency resource demand information of each candidate set and power control parameters required to be adopted by each AP in the AP coordination set; and the first AP sends TWT SP decision information to each second AP in the AP coordination set.

The invention discloses a steel plate defect collection method and system based on improved DBSCAN and regional distance, and relates to the field of steel plate defect collection, and the method comprises the following steps: collecting image data of a steel plate with defects; a steel plate defect collection model is constructed, the steel plate defect collection model firstly adopts regional distance to process defects, then utilizes DBSCAN to perform preliminary clustering on data, divides intervals with different densities, and utilizes a K-dist graph to extract distance information in each interval; then, generating Eps for clustering according to distance information in the interval; and finally, distributing the noise points in each interval to corresponding clusters according to a preset rule. And completing defect collection of the steel plate in the image data by using the steel plate defect collection model. The invention provides a steel plate defect collection method based on improved DBSCAN (Density-Based Spatial Clustering of Applications with Noise) and regional distance. The steel plate defect collection method shows excellent clustering performance when processing complex and intensively distributed defects.

This design can not only construct a vehicle energy model and simulate the temperature change process of the vehicle, but also has strong adaptability and can meet the strategy generation needs of different vehicle models.

The present application relates to a kind of vertical rotation step-by-step half-through tied arch bridge main arch ring construction method, and arch ring is divided into two half spans and is laid on two shore approach on the bed, adopts vertical rotation buckle and hangs system and pulls arch ring vertical rotation, while using jacking system and jacks arch ring to move to midspan, repeatedly jacks, vertical rotation, gradually moves two half span arch ring to midspan closure.The present application combines jacking method and vertical rotation method organically, on the one hand, solves the problem that existing jacking method can only jacking whole span and is limited by span, on the other hand, solves the problem that existing vertical rotation method cannot be applied when there are obstacles in arch seat position, successfully realizes large-span main arch ring jacking installation.Whether it is bridge across navigable river or bridge across deep valley, whether river bank is gentle terrain or steep mountain, the present application can be applied, and large equipment is less, and construction risk and cost are low.

This invention discloses a method for continuous preparation of in-mold foamed beads, relating to the field of polymer materials. The method includes: opening a gate to release a suspension polymerization solution, which has undergone high-speed shearing, into a storage tank; injecting the solution into the feed inlet of a spiral coil at a certain rate; and turning on a hot water heating jacket to a certain temperature. After a certain time, the beads reach the discharge sieve at the bottom of the spiral coil. Once a certain quantity is reached, the beads in the sieve are transferred to an oven for heat treatment, where they undergo in-mold foaming and solidification to obtain irregularly shaped parts. By preparing spherical PMI particles using suspension polymerization technology and applying a continuous production line to mass-produce in-mold foamed beads, the problems of poor dispersion, difficult adhesion, environmental pollution, and industrialization are effectively solved.

The application relates to the computer technology field and provides a compiling method, device and system, a plurality of second compiling files are generated through a plurality of second compilers of second versions, and the subsequent inline optimization through different version compilers is facilitated. In the application, the consistency of the compiler versions used globally does not need to be ensured, the target second compiling file is determined from the generated plurality of second compiling files in the compiling process, the subsequent inline optimization of the first compiling file can be performed, the compiling flexibility is improved, and the problems that the inline optimization cannot be performed or the inline optimization exposes the function file source code when the first compiler and the second compiler are of different versions are solved.
