The invention relates to an internet-of-things five-primary-color full-spectrum multi-color-temperature LED peak shifting energy storage intelligent street lamp digital platform. The street lamp comprises a power supply interface of a public power grid for supplying power to a lighting module and / or a power storage module in a first time period, and a power supply interface of the power storage module for supplying power to the lighting module in a second time period; monitoring and calculating a first damage rate according to the first time interval; marking the street lamp with the first damage rate higher than a first preset value as a low-efficiency street lamp; and according to the extra electricity price cost and the maintenance operation cost of the low-efficiency street lamps, the cost-benefit index of each planning area is determined, the maintenance time is adjusted based on the maintenance priority between the determined planning areas, and a target maintenance work sheet is obtained for maintenance. When it is judged that the first damage rate is higher than a first preset value, updating to monitor and calculate a second damage rate according to a second time interval, and updating the mark of the first street lamp; and updating the cost-benefit index in each planning area. And the cost is reduced, and the facility safety and utilization rate are ensured.

This invention discloses an adjustable antenna-assisted dynamic beamforming optimization method for vehicular networks, belonging to the field of vehicular network and mobile communication technology. By establishing a comprehensive near-field multipath channel model incorporating scattering cluster distribution and geometric phase shift characteristics, this invention utilizes the position reconfigurability of a fluidic antenna system to achieve dynamic port switching within the limited space of the vehicular network terminal. This transforms multipath interference in near-field rich scattering environments into spatial diversity gain, solving the scientific problem that fixed ports cannot adapt to complex channel characteristics. Simultaneously, this invention proposes a low-complexity joint optimization algorithm based on the maximum transmission ratio and maximum signal-to-noise ratio criteria. Through closed-form solutions, it rapidly achieves the joint design of base station beamforming and terminal ports, significantly improving channel capacity without requiring only a single radio frequency link or increasing hardware costs. This effectively overcomes the stringent economic constraints of large-scale commercialization on hardware costs and computational latency.

The disclosed embodiment discloses a data replication method, a data storage system control method, an apparatus, a device and a medium, wherein the method comprises obtaining a data capture bandwidth and a data access frequency, wherein the data capture bandwidth is the bandwidth occupied when capturing data from a source data storage space to a target data storage space, and the data access frequency is the number of times data is captured from the source data storage space per unit time; in response to the data capture bandwidth being greater than or equal to the target bandwidth and / or the data access frequency being greater than or equal to the target access frequency, the data in the source data storage space is copied to the target data storage space. This solution enables a user to directly read data originally stored in the source data storage space from the target data storage space without the need to capture data from the source data storage space to the target data storage space, thereby saving communication costs and reducing the burden of data processing, while reducing the delay when the user reads data, thereby improving the user experience.

This invention discloses a SOTIF data acquisition method and related equipment. In this invention, the cloud has a large data acquisition scope, thereby reducing reliance on closed sites or professional data collection fleets, and lowering the acquisition cost of multi-source heterogeneous data. Furthermore, First Automobile Works filters its collected multi-source heterogeneous data using first Shannon entropy and residual risk values. The filtered multi-source heterogeneous data corresponds to traffic environments with high levels of disorder. Therefore, by calling First Automobile Works to collect and upload multi-source heterogeneous data, a large amount of multi-source heterogeneous data that meets the application conditions of SOTIF can be easily obtained, providing data support for SOTIF. Moreover, the SOTIF data acquisition method is executed on the vehicle side, and by uploading the filtered multi-source heterogeneous data instead of the original full-volume data, the data processing burden on the cloud is significantly reduced, improving the implementation efficiency of SOTIF. This invention has wide applications in the automotive technology field.
